Description
Support Devices
The present invention relates to support devices for the medical device components and related systems.
Many medical procedures require a patient to be connected to a catheter in order to allow drainage, or the administration of fluids or gases to a patient. Typically, the catheter comprises a tube or hose which terminates in a connection hub to which a medical practitioner may connect a medical device, such as a syringe, in order to be able to drain or administer fluids or gases. Once a catheter has been inserted into a patient, the tube extending from the patient which terminates at the connection hub is typically left free for fluid flow while a practitioner connects a medical device (such as a syringe) to the connection hub. During a medical procedure, in order to connect a medical device to the connection hub, a practitioner must first grasp the medical device and also grasp the connection hub in order to connect the two together. Due to the relatively small size of a typical connection hub, in grasping it a practitioner will come into contact with a large proportion of the hub and thus the risk of contamination is relatively large. This is further problematic as, during many medical procedures, one of the practitioner’s hands is often occupied on the patient, for example manipulating an ultrasound probe, palpating the patient or applying pressure to a part of the body. At present a practitioner has to use both hands to connect a medical device to the connection hub, which is of course undesirable as this prevents the practitioner’s hands from being able to continue carrying out a procedure on the patient, e.g. applying pressure to a part of the body.. For example, a catheter hub may be used in interventional procedures such as plexus anaesthesia (repeated injections with intermittent refilling of syringe or the use of multiple syringes in the same injection sequence) and rheumatology (aspirations and aseptic re-injections via same hub/needle/catheter).
There remains a need for equipment that facilitates improved and aseptic connections between a medical device (such as a syringe) and a connection hub (such as a catheter hub or hose hub) during medical procedures.
The present invention seeks to address or at least mitigate the problems outline above and thus when viewed from a first aspect there is provided a system comprising a medical device component and a support device for the medical device component;
wherein the medical device component comprises:
-2a connection hub comprising a connection feature arranged at a first end of the connection hub for connecting the connection hub to a medical device; and a fluid transfer hose extending from a second end of the hub, wherein the fluid transfer hose has a fluid flow path extending therethrough; and wherein the support device comprises:
at least one support arrangement, for supporting the medical device component, comprising a receiving portion shaped to receive both the second end of the connection hub and the associated fluid transfer hose extending therefrom such that, when the second end of the connection hub is inserted into the receiving portion in use, the receiving portion is shaped to support the connection hub in a predetermined position and shaped to accommodate the fluid transfer hose extending therefrom in a manner such that the fluid flow path extending through the fluid transfer hose is substantially unimpeded.
The multi-part system according to the present invention provides a kit which may significantly improve the ease of connection to medical device components during a medical procedure. As will be appreciated by those skilled in the art, the support device, within the system, provides a means for supporting a medical device component comprising a connection hub and associated fluid transfer hose without impeding the fluid flow through the fluid transfer hose. Once the medical device component is supported within the support device, a practitioner may more easily connect/disconnect a medical device to/from the medical device component. For example, before carrying out a medical procedure, a practitioner may insert the connection hub of a medical device component, which is not yet connected to a medical device, into the support device. Subsequently, during a medical procedure, a practitioner may more easily connect a medical device to the connection hub of the medical device component because it is supported by the support device. As will be discussed in more detail below, the support device may present the connection hub of the medical device component in a manner which provides for improved ease of connection. The support device may allow a practitioner to connect a medical device to the connection hub without having to physically grip the support device.
Advantageously, the support device in such systems is able to accommodate the fluid transfer hose of the medical device component due to the shape of the receiving portion. As will be appreciated by those skilled in the art, in order to be able to connect a medical device to the connection hub of the medical device component, the first end, i.e. the ‘connection end’ must be accessible and thus this inevitably results in the second end, i.e. the end from which the fluid transfer hose extends, being the end which is inserted into the receiving portion. Without the ability to accommodate the hose, the support device would likely impede the flow of fluid
-3 through the hose and this is likely to interfere with the medical procedure being carried out. In this instance a practitioner would have to remove the medical device component from the support device following connection to resume fluid flow. This is not practical for repeated injections and many medical procedures require an uninterrupted fluid flow. Accordingly, the support device of the present invention allows a medical device component to be continually supported and continue to be functional (e.g. in terms of fluid flow through the fluid transfer hose) even whilst supported by the support device.
As the support device only supports the medical device component which itself is capable of transferring fluid, the support device does not need to be biocompatible with the fluid being transferred. Accordingly, the support device of such systems is advantageously able to support a variety of different medical device components which may be used for the transfer of different fluids.
In such systems the receiving portion is shaped to support the connection hub in a predetermined position. It should be understood that the predetermined position is a position which is pre-defined by the supporting shape of the receiving portion such that if, for example, the same medical device component were to be repeatedly removed and re-inserted into the support device, its connection hub would be supported in the same position each time. At least for stability purposes, the receiving portion may be arranged to support the connection hub in a predetermined position towards a base of the support device.
As will be appreciated by those skilled in the art, prior to insertion into the support device, the fluid transfer hose comprises a fluid flow path extending therethrough which will allow fluid to flow at a pre-defined flow rate for a given flow velocity or pressure drop along the hose. The flow rate is pre-defined by the diameter and cross-sectional area of the hose. If the hose has a varying diameter or cross-sectional area along its length then the pre-defined flow rate may be an average taking into account such variations. It will be understood that the receiving portion being shaped to accommodate the fluid transfer hose in a manner such that the fluid flow path is substantially unimpeded means that, when the medical device component is inserted into the support device, the pre-defined flow rate through the fluid flow path is substantially unchanged. It will be appreciated that the fluid transfer hose may be deformed/bent into a different shape/arrangement while being accommodated by the receiving portion, but the fluid flow path extending therethrough will have substantially the same pre-defined flow rate as that prior to the medical device component being inserted into the support device.
-4The connection feature at the first end of the connection hub may be any suitable connection feature which facilitates the connection of the hub to a medical device in use. For example, the connection feature may be in the form of an external thread provided on an outside surface of the connection hub and/or an internal thread provided on an inside surface of the hub. Alternatively, or in addition, the connection feature may comprise a female tapered socket formed in the first end of the hub or a male tapered tip formed at the first end of the hub. In at least some embodiments, the connection feature may comprise a male or female Luer connector in accordance with ISO 80369-7. In at least some other embodiments, the connection feature may comprise an ENFit connector in accordance with ISO 80369-3. In at least some other embodiments, the connection feature may comprise an NRFit connector in accordance with ISO 80369-6. As a further alternative, in some other embodiments the connection feature may simply comprise a rim or lugs extending from an outside surface at the first end of the hub, e.g. to provide a positive fit or bayonet connection. As will be appreciated, the connection feature may comprise a combination of different features, for example a combination of one or more of the examples given above.
According to a further aspect of the present invention there is provided a support device for a medical device component of the type comprising a connection hub comprising a connection feature, arranged at a first end of the connection hub for connecting the connection hub to a medical device, and a fluid transfer hose extending from a second end of the hub, wherein the fluid transfer hose has a fluid flow path extending therethrough, the support device comprising: at least one support arrangement, for supporting the medical device component, comprising a receiving portion shaped to receive both the second end of the connection hub and the associated fluid transfer hose extending therefrom such that, when the second end of the connection hub is inserted into the receiving portion in use, the receiving portion is shaped to support the connection hub in a predetermined position and shaped to accommodate the fluid transfer hose extending therefrom in a manner such that the fluid flow path extending through the fluid transfer hose is substantially unimpeded.
There will now be described some embodiments, which may be taken alone or in combination, that relate to the first and second aspects of the invention.
As is mentioned above, the receiving portion is shaped to support the connection hub in a predetermined position. The receiving portion may take any suitable form that provides such support. However, in a set of embodiments the receiving portion comprises a cavity with at least one side wall which at least partially defines a shape that is complementary to the shape of the
- 5 connection hub. By having a complementary shape it ensures that the hub is supported in the predetermined position. In some examples the side wall(s) may define a shape that is complementary by substantially matching the shape of the connection hub. However, the exact profile of the at least one side wall need not necessarily match that of the hub and instead the at least one side wall may define a more general profile which complements the shape of the hub. For example, the at least one side wall may comprise a plurality of lugs, extending into the cavity, at least the tips of which define a complementary shape to that of the hub.
The at least one side wall of the cavity must be shaped in such a manner that it is capable of supporting the connection hub but also such that is capable of accommodating the fluid transfer hose. Therefore, in a set of embodiments, the at least one side wall extends at least 180° around the hub so as to support the hub and less than 360° so as to accommodate the fluid transfer hose. The at least one side wall may extend continuously or be split into separate supporting wall segments. For example, the at least one side wall may extend up to 270° around the hub, leaving at least a 90° gap in the at least one side wall for the fluid transfer hose to pass through and thus be accommodated. More generally, the at least one side wall may comprise a gap arranged to allow the fluid transfer hose to pass out through the side wall. Such a set of embodiments may only allow for the medical device component to be inserted in a specific angular orientation. Alternatively, in another set of embodiments, the at least one side wall may comprise multiple supporting wall segments that are separated by an angular extent, for example each supporting wall segment extending up to 30° around the hub and being separated by an angular extent of up 30°. The supporting wall segments may be positioned around the hub at multiple different angular locations so as to provide an overall supporting function. It will be appreciated that the total angular extent of the multiple supporting wall segments may be less than 180°. As will be appreciated, such an arrangement may allow the medical device component to be inserted into the support device in multiple different angular positions, which may make insertion easier.
The receiving portion may take any shape such that it supports the hub and accommodates the fluid transfer hose, i.e. the fluid transfer hose is able to leave the receiving portion in a manner such that the fluid flow therethrough is substantially unimpeded. In a set of embodiments, the receiving portion comprises a cavity with a base portion having an aperture arranged to allow 5 the fluid transfer hose to pass out through the base portion. The cavity may optionally be complementarily shaped as described above. In such embodiments, the aperture may be surrounded by a rim arranged to engage with the second end of the hub. Such a set of
-6embodiments is advantageous as there is provided a clear aperture for the fluid transfer hose to pass out through, thus reducing the likelihood of the flow through the fluid transfer hose being impeded. Additionally, the rim around the aperture provides a stop to engage with the second end of the hub, giving a clear indication during insertion of the medical device component into 5 the receiving portion that the component has been fully inserted, i.e. feedback to a user when the second end of the hub comes into contact with the rim of the aperture.
The receiving portion is shaped to receive both the second end of the connection hub and the associated fluid transfer hose extending therefrom. In various embodiments, the cavity of the receiving portion may be formed as two distinct receiving portions. In a set of embodiments, the 10 receiving portion comprises a cavity with an opening comprising a hub receiving portion, for receiving the connection hub, and the opening further comprising a hose receiving portion, for receiving and accommodating the fluid transfer hose. As will be appreciated, at the opening the hub receiving portion need not necessarily be capable of supporting the hub, it merely needs to be capable of allowing the hub to pass into the cavity where it may be supported. In addition, 15 the hose receiving portion simply needs to allow a user to insert the second end of the hub into the cavity and to accommodate the fluid transfer hose. The provision of the hose receiving portion helps to ensure that the fluid flow through the hose remains unimpeded following insertion of the medical device component into the support device. The hose receiving portion may take any suitable shape and/or form.
In a set of embodiments, the hose receiving portion of the opening is in the form of an elongate slot extending away from the hub receiving portion of the opening. In a preferred set of embodiments, the elongate slot has a width which is at least equal to the outermost diameter of the fluid transfer hose. Such a width may help to ensure that the fluid flow rate through the hose is substantially unimpeded. In a set of embodiments, the elongate slot extends away from the hub receiving portion of the opening in a direction (e.g. downwards direction) towards the base portion of the cavity. In a set of potentially overlapping embodiments, the elongate slot extends away from the hub receiving portion of the opening in a direction away from the connection hub.
In a set of embodiments, the receiving portion is arranged to provide a friction fit with the connection hub. For example, the receiving portion is shaped to provide the friction fit, i.e. the receiving portion has slightly smaller internal dimensions than the external dimensions of the hub such that a friction fit is established. In another potentially overlapping set of embodiments the friction fit is provided by a resilient, flexible tab extending into the receiving portion arranged such that insertion of the connection hub into the receiving portion deforms the tab creating a
-7 friction fit with the hub. As will be appreciated, the friction fit may be created by a combination of the receiving portion being shaped to provide a friction fit and the provision of the above described tab.
In a set of embodiments, the support device comprises a space, arranged below the at least one support arrangement, for the hose to extend into/through. As discussed previously, in order to ensure that the medical device component remains functional, the flow through the fluid transfer hose must remain substantially unimpeded. The provision of a space below the at least one support arrangement may provide for a greater space for the fluid transfer hose to extend into and bend without causing any obstruction to the flow of fluid therethrough. Ideally the hose has space to extend away from the connection hub, below the support arrangement, without coming into contact with a work surface on which the support device is resting, so that the hose is not compressed.
The support device may only be suitable for supporting one type of medical device component, i.e. a component with a connection hub of specific dimensions and/or with a fluid transfer hose of specific size. However, the Applicant has recognised that it may be advantageous for the support device to be capable of supporting a variety of different medical devices components comprising connection hubs and/or hoses that each potentially have different dimensions. Accordingly, in a set of embodiments, the receiving portion is shaped and/or sized to receive a variety of different sized medical device components. For example, the receiving portion may comprise a tapered cavity that can support connection hubs which have different external dimensions, for example those with difference maximum widths/diameters. For example, the receiving portion may comprise an opening sized to accommodate fluid transfer hoses which have different external diameters.
The support device advantageously allows a practitioner to more easily connect a medical device to the medical device component being supported by the support device. In a set of embodiments, the predetermined position is a substantially vertical position wherein the first end of the connection hub is substantially above the second end of the connection hub. Supporting the connection hub in a substantially vertical position, and thus presenting the connection feature at the first end of the hub, may make it even easier for a practitioner to connect a medical device to the connection hub. Further, by supporting the connection hub in a substantially vertical position, when a practitioner decides to connect a medical device to the hub, any force applied may largely be in the vertical direction. By applying the force in this vertical direction, it may substantially apply force through the support device in a vertical
- 8 direction and thus may reduce the likelihood of the support device sliding along a surface it is placed on. This may help to ensure that the practitioner obtains the desired level of connection with the hub, which may be important e.g. where high pressure fluid connections are used.
The medical device component may be inserted into the support device and the connection hub supported by the receiving portion without any medical device being connected to the hub of the medical device component. For example, a practitioner may insert the medical device component into the support device such that they can easily connect a medical device to the hub later during a medical procedure, thus making the medical procedure easier at a later stage. Alternatively, or in addition, a practitioner may insert a medical device component into the support device whilst it remains connected to a medical device. For example, the medical device component may be connected to a syringe which a practitioner manipulates to insert the medical device component into the support device. Once the connection hub is supported by the receiving portion, depending on the specific procedure being carried out, the practitioner may wish to disconnect the medical device from the medical device component. This may be achieved via various means. It may be possible for a practitioner to separate the medical device from the medical device component without needing to manually grip the medical device component in any way. For example, using one of the Applicant’s disconnection systems as described in WO2013/164358, W02015/014914 or WO2016/162571, the contents of each of which are hereby incorporated by reference. Using the type of medical devices (e.g. syringes) seen in these documents, a practitioner may simply insert the medical device component into the support device and then operate the disconnection mechanism on the medical device leaving the supported medical device component separate from the medical device.
However, it may not be possible to disconnect the medical device component using the medical device alone. If no disconnection mechanism is provided, then the support device may instead be capable of facilitating disconnection. For example, if the connection feature comprises a threaded connection, the medical device component may be supported within the support 5 device in such a manner that it cannot rotate. In one or more embodiments, the receiving portion supports the connection hub so as to prevent rotation of the connection hub relative to the support arrangement. In this instance a practitioner may, if necessary, grip the support device and proceed to unscrew the medical device from the connection hub. As will be appreciated, this avoids the practitioner from coming into direct contact with the connection hub, 10 promoting aseptic techniques. Supporting the medical device component in a manner such that it does not rotate may be achieved solely via a friction fit between the receiving portion and the connection hub. However, in a set of embodiments, the connection hub comprises at least one
-9protrusion extending therefrom, and the at least one support arrangement comprises a protrusion receiving portion shaped to receive the protrusion on the hub. This means that, when the medical device component is inserted into the at least one support arrangement, receipt of a protrusion within a protrusion receiving portion inhibits rotation of the connection hub relative to the at least one support arrangement.
Furthermore, the Applicant has recognised that, particularly where there is no disconnection mechanism provided on the medical device, it is advantageous to have a means for positively gripping the medical device component in order to assist with the disconnection of the component from a medical device. In a set of embodiments, the at least one support arrangement comprises at least one latch arranged to latch onto the hub and prevent movement of the supported connection hub in at least one direction. The Applicant has recognised that such a latch is advantageous as it may allow a user, for example, to separate a component and medical device which are connected by a friction fitting of the connection hub. In a set of embodiments, the latch prevents upward/vertical movement. However, it may not necessarily be exclusively used for this purpose and may also be used to assist in gripping the component when detaching a threaded connection. In a set of embodiments, the latch only prevents movement in one direction, for example the vertical direction. Such a set of embodiments may be advantageous as it may allow a practitioner to insert the medical device component into the at least one support arrangement, disconnect a medical device aided by the gripping of the connection hub by the latch, and then subsequently re-connect the medical device. Even without a medical device connected to the hub, in such embodiments it may be possible to selectively remove the medical device component by moving the medical device component out of the at least one support arrangement in a direction which is not prevented by the at least one latch, e.g. by sideways movement.
The support device may comprise any number of support arrangements and the exact number may be tailored towards use in a specific type of procedure where a pre-determined number of medical device components will require support. However, in a preferred set of embodiments the support device comprises at least three support arrangements, for example arranged equiangularly around the support device.
The Applicant has recognised that the support device may advantageously support further medical device components, in particular one or more medical device components that do not include a connection hub or fluid transfer hose. Therefore, in a set of embodiments, the support device comprises at least one further support arrangement, for supporting a further medical
- 10device component. The further medical device component may be any relevant medical device component, for example a needle assembly, a connector, a clamp, however in a preferred set of embodiments the further medical device component comprises an ampoule and/or vial. It will be appreciated that such a set of embodiments is particularly advantageous as the support device provides a solution which is capable of supporting multiple different components which ideally are not held by a practitioner and which are typically used together in a single procedure. For example, prior to carrying out a procedure, a practitioner may first arrange a medical device component within the support device such that the connection hub is supported by the receiving portion. They may then open an ampoule and arrange it within the further support arrangement. A practitioner may then proceed to carry out a procedure on a patient without having to physically hold the ampoule or medical device component at any stage, thus leaving at least one hand free to carry out any necessary procedure on the patient.
In addition to the use of a medical device component as claimed, along with the optional further medical device components described above, many medical procedures also require the use of a needle assembly. Such a needle assembly may be used for various purposes, for example to administer/extract a fluid to/from a patient, or alternatively to extract a fluid from, for example, an 5 ampoule prior to administration to a patient via the supported medical device component. In this instance, following extraction of the fluid from an ampoule, which may also be supported by the support device as described above, into a medical device via a needle assembly, the needle assembly must be safely discarded prior to connection of the medical device to the medical device component. Such needle assemblies are typically ultimately disposed of in a sharps 10 container, however such a container is not always easily and immediately accessible during a medical procedure and such devices may often be temporarily unsafely discarded, for example onto a tray. The Applicant has recognised that the support device may also advantageously be used as a means for housing new and/or used needles. Accordingly, in a set of embodiments, the system further comprises a pierceable block of material supported by the support device. In 15 such a set of embodiments the system may further comprise at least one needle assembly. As will be appreciated, following use of a needle assembly a practitioner may safely discard the needle assembly by pushing it into the pierceable block of material.
Following the end of a medical procedure, the support device, along with the pierceable block of material now containing one or more used needles, may be discarded in its entirety. However, it may be more efficient to dispose of the used needle assemblies separately to the support device itself, which may not necessarily need to be disposed of and may be reused following sterilisation. Accordingly, in a set of embodiments, the support device supports the pierceable
- 11 block in a releasable manner. For example, the pierceable block of material may be engaged within a deformable cavity of the support device which may be deformed to release engagement of the block. In such a set of embodiments, when it is desired to remove the pierceable block of material from the support device, a practitioner may simply deform the deformable cavity in order to release engagement of the pierceable block.
When a practitioner connects a medical device to the medical device component supported by the support device, due to the fact that the connection hub is often relatively small, a practitioner may easily misplace, for example, the tip of the medical device and miss the connection hub. Therefore, in a set of embodiments, the support device further comprises at least one upstanding wall, separated from, and extending at least partially around the at least one support arrangement. Advantageously, when the support device comprises at least one upstanding wall, when a misconnection occurs and the medical device comes into contact with the support device in a region between the at least one support device and the at least one upstanding wall, further movement of the medical device may be stopped by the at least one upstanding wall. This may help to prevent the medical device from coming into contact with a potentially nonaseptic work surface on which the support device may rest, which may even be a patient, depending on where the support device rests.
In a further set of embodiments, the at least one upstanding wall comprises a perimeter wall which extends around substantially all of the at least one support arrangement so as to define a well between the at least one support arrangement and the perimeter wall. Such a perimeter wall will also help to prevent a misconnected medical device from coming into contact with a non-aseptic surface. Additionally, as will be appreciated by those skilled in the art, the medical device component comprising the connection hub and fluid transfer hose may be used to transfer fluids to and/or from a patient. In a situation where the medical device component is used to transfer fluid to a patient, this will typically require a practitioner to connect a medical device, e.g. a syringe, which contains a supply of fluid. As will be appreciated, the connection hub may be presented in a vertical manner, thus typically requiring the medical device to be presented in a downward manner. As will be appreciated by those skilled in the art, presenting a medical device filled with a fluid, e.g. a syringe, towards the hub of the medical device component may result in at least a small amount of liquid escaping from the medical device before being fully connected to the medical device component. Advantageously, the well defined by the perimeter wall may act to retain any fluid dripped from a medical component or leaked from the medical device component while it is being supported. The perimeter wall
- 12extending around the support device may also improve stiffness of the support device, which may be advantageous e.g. if the support device is made from plastic.
In a further set of embodiments, the support device further comprises at least one drain hole arranged to permit the outflow of fluid from the well. This may allow for the draining of any fluid collected, for example prior to moving the support device to a work area.
In a set of embodiments, the support device comprises a base structure arranged, in use, to rest on a work surface. In use, a practitioner may connect a medical device, e.g. a syringe, to the connection hub of the medical device component. The practitioner may then grasp and lift the medical device, which may result in the support device being lifted away from a work surface, and remain attached to the medical device component. The practitioner may then proceed to operate the medical device, e.g. by applying a force to the plunger of a syringe, and then subsequently proceed to place the support device with the supported medical device component and attached medical device, back down on the work surface. However, the Applicant has recognised that a practitioner may not always choose to lift the medical device during operation and may instead choose to operate the medical device whilst it is connected to the medical device component and thus effectively supported by the support device resting on a work surface. As will be appreciated, typical medical devices which may be used may be elongate, e.g. such as syringes, and may be relatively heavy, e.g. due to being filled with a fluid. Preferably, therefore the base structure provides a stable support for the support device. In a set of embodiments, the base structure is arranged in a tripod. As will be appreciated, a tripod structure may provide the necessary stability to ensure that the medical device is supported by the support device, when attached to the medical device component supported therein. Such a base structure may also be advantageous in ensuring that the support device is kept stable when a medical device is connected to the medical device component supported within the support device.
When a practitioner wishes, for example, to engage a syringe with a connection hub held in the support device, they may simply insert, for example the male tip of the syringe into the female end of the connection hub, as it is supported by the support device. A practitioner may hold the syringe in one hand and their other hand may be occupied, for example carrying out a procedure on the patient. Accordingly, it may be beneficial for the practitioner to be able to engage a medical device such as a syringe with the connection hub without having to manually grip the support device. As will be appreciated, the force required to positively engage the
- 13 connection hub and the medical device may be significant. Depending on the particular arrangement of the receiving portion within the support device, the support device may tend to move across a surface during connection. Therefore, in a further set of embodiments, the support device comprises at least one anti-slip pad arranged on the base structure for preventing movement of the support device relative to a surface it is placed on in use. The provision of at least one anti-slip pad may reduce the tendency for the support device to move across a surface and thus may facilitate one-handed connection of a medical device to the hub held within the support device. This also has a further advantage in that it minimises the practitioner's contact with the support device, and hence the components supported therein, and thus reduces the risk of contamination of the support device and supported components. In a set of embodiments, the anti-slip pad comprises at least one of: an adhesive pad, a rubber pad, a foam pad, or a Velcro pad. Alternatively, the base structure may comprise a gripping arrangement which is arranged to grip onto a work surface, or a part attached thereto. The gripping arrangement may take any suitable form, for example a clamp member. In other examples, the base structure may comprise a plug or socket that is compatible with a corresponding socket or plug on a work surface.
In a set of embodiments the support device comprises at least one stacking feature arranged to co-operate with a complementary feature on another support device, such that at least two support devices can be stacked on top of one another. The ability to stack multiple support devices on top of one another may reduce the storage space required to store large number of the support devices. As will be appreciated, in a medical environment a large number of the support devices may be used and thus this feature may be advantageous. The stacking feature may take any suitable form, for example a cylindrical tube extending upwards from the support device. A corresponding receptacle may be arranged on the base of the support device for receipt of the cylindrical tube of a further support device.
In a set of embodiments, the support device further comprises a holding arrangement for engaging the fluid transfer hose of the medical device component and holding it in a fixed position in which the fluid flow path therethrough is substantially unimpeded. This may, for example, comprise a partially circular, e.g. horseshoe shaped, channel within the support device, into which the fluid transfer hose may rest. This channel may have a diameter, or widest extent which is substantially the same as the diameter or widest extent of the fluid transfer hose. As will be appreciated, initial insertion of the fluid transfer hose into the channel through its narrowest point may cause the fluid flow path to be impeded, however once fully inserted into the flow path would then be substantially unimpeded. As another example, a forked section
- 14capable of gripping onto the fluid transfer hose in a manner in which its fluid flow path is unimpeded, may be provided.

Figure 1 shows a perspective view of a support device 2 according to a first embodiment. The support device 2 comprises three support arrangements 4 arranged equiangularly around the support device 2. However, this particular arrangement is not essential and the support arrangements 4 may be arranged in any suitable manner. In this embodiment each of the three support arrangements 4 is identical, however this is also not essential, and each may be shaped and/or proportioned differently so as to be capable of each supporting different medical device components. Each support arrangement 4 comprises an opening comprising a connection hub receiving portion 6 and a hose receiving portion 8 each of which extend into a cavity 10 which is capable of supporting a connection hub of a medical device component (seen
- 15 in Figures 6a-f). Each of the cavities 10 are defined by a side wall 12 which further defines protrusion receiving portions 14a-f arranged on opposite sides of each cavity 10. Each cavity 10 further comprises a resilient, flexible tab 16 which extends along an axial direction of each cavity 10. The support device 2 further comprises a stacking feature, in the form of cylindrical protrusion 18, which extends upwardly from an upper surface 20 of the support device 2. This cylindrical protrusion 18 may also be used to receive and support a medical device.
The support device 2 further comprises three upstanding walls 17 extending from the upper surface 20 of the support device 2. These upstanding walls 17 may help to avoid a medical device from coming into contact with an aseptic surface when a misconnection between the medical device and the medical device component. The purpose of these upstanding walls will become more apparent later with reference to Figure 5e.
In this embodiment, the cavity 10 of each support arrangement 4 is arranged in a vertical manner so as to be capable of supporting a medical device component in a vertical arrangement.
Figure 2 shows an underside perspective view of the support device 2 seen in Figure 1. This view more clearly shows the presence of a base portion 22 of each cavity 10. The base portion 22 of each cavity 10 comprises an aperture 24 which is defined by a rim 26. The purpose of the aperture 24 and rim 26 is explained in more detail later with reference to Figures 6 and 7. The underside of the support device 2 is generally hollow, as can be seen in this Figure, and this helps to facilitate the stacking of one support device 2 onto another, as can be seen in Figure
18.
Figure 3 shows a view of the support device 2, when viewed substantially from above the support device 2. This view more clearly shows how each cavity 10 terminates at the base portion 22 of each cavity 10. The aperture 24, in each base portion 22, is defined by a rim 26 which is generally in the form of a C-shape. Accordingly, the aperture 24 is not fully surrounded by the rim 26 and thus there is a cut-out portion 28. The aperture 24, including the cut-out portion 28, facilitates the passing of a fluid transfer hose through the cavity 10. Furthermore, the side wall 12 of each cavity 10 does not extend completely each cavity, and in this particular embodiment extends approximately 300°. This leaves an opening in the form of a slot 30 extending along the length of the cavity and into the aperture 24. This slot 30 accommodates the fluid transfer hose of the medical device component as it is inserted into the cavity 10.
- 16Figure 4 shows a close-up view of one of the support arrangements 4 when viewed from above. This view more clearly shows the presence of the protrusion receiving portions 14a-f. In this particular embodiment the protrusion receiving portions 14a-f are in the form of slots, however this is not essential, and they make take any form that is suitable for receiving any protrusions on the medical device component. The protrusion receiving portions 14a-14f are defined by the side wall 12 of the cavity, specifically by lugs 12a-d which form part of the side wall 12 and extend towards the centre of the cavity 10.
Figures 5a-5f illustrate the insertion of a medical device component 32, hereinafter referred to as a component, into a support device 2. In this particular example, the component 32 is attached to a medical device in the form of a syringe 2. Figure 5a illustrates the stage just as the component 32 is initially inserted into the support arrangement 4. As seen in in this Figure, the component 32 comprises a connection hub 36, hereinafter a hub 36, comprising a first end 38 to which the tip 40 of the syringe 34 is connected to. This connection is achieved by the interaction of the tip and a connection feature on the first end which cannot be seen in this particular Figure. In this particular example the connection feature is in the form of a tapered socket provide on the hub 36, e.g. a Luer-type hub. The hub 36 further comprises a second end 42 from which a fluid transfer hose 44 extends.
In order to insert the component 32 into the support arrangement 4, the fluid transfer hose 44 is first aligned with, and inserted into, the hose receiving portion 8. Once the fluid transfer hose 44 is within the hose receiving portion 8, the component 32 can be further advanced into the support arrangement 4. A further advanced position can be seen in Figure 5b whereby the component 32 has been fully inserted into, and supported by the support arrangement 4, on the support device 2. It can be seen that when the component 32 is supported by the support arrangement 4 the fluid transfer hose 44 of the component 32 passes freely out of the support device 2 and is free to allow the transmission of a fluid therethrough.
Once in the fully supported position, the syringe 34 may be disconnected from the component 32. In this particular embodiment, the syringe 34 comprises a disconnection member 46 in the form of a lever member. Operation of the disconnection member46 can be seen in Figure 5c. When a practitioner wishes to disconnect the syringe 34 from the component 32, they simply apply a force to the disconnection member 46, causing it to pivot and push the component 32 away from the tip 40 of the syringe 34. The use of a disconnection member on the syringe 34 is not essential, and the support device 2 may support the component 32 and grip onto the hub 36 in a sufficient manner that it is possible to disconnect the syringe 34 from the component 32 by
- 17pulling and/or twisting the syringe 34 relative to the supported component 32. As will be appreciated, this may require a practitioner to physically grip the support device 2.
Figure 5d shows the stage at which the syringe 34 has been fully separated from the component 32. At this point the component 32 is fully supported in the support device 2. As is apparent, the support device 2 supports the component 32 in a vertical position such that the first end 38 of the hub 36, i.e. the end to which the syringe 34 was previously connected, is presented upwards. Presenting the first end of the hub 36 in this manner helps to facilitate the simple connection of further devices to the component 32.
After separation of the syringe 34 and the component 32, the syringe 34 may, for example, be refilled with another fluid for administration to a patient. In this instance, following refilling the syringe may simply be reattached to the component 32. When connecting the syringe 34 to the component 32, a practitioner may achieve a successful connection first time. However, due to the fact that the component 32 is relatively small, and the practitioner may be operating the syringe 34 using a single hand, on at least the first attempt at connection to the component 32 they may miss. In this instance, the support device 2 advantageously helps to avoid the syringe 34 from coming into contact with an aseptic surface. As seen in Figure 5e, the tip 40 of the syringe 34 may come into contact with the upper surface 20 of the support device 2, and any further movement may be stopped by the tip 40 coming into contact with one of the upstanding walls. This may help to prevent the syringe 34 from coming into contact with a work surface on which the support device 2 rests, or alternatively a practitioner’s hand if they are holding the support device 2.
The remaining support arrangements 4 may be utilised by further medical device components. Once the component 32 is supported in the device in the claimed manner in which the fluid flow through the fluid transfer hose 44 is substantially unimpeded, a variety of different medical devices may be connected to the component 32, potentially multiple times. As discussed previously, this may involve a practitioner grabbing the support device 2 in one hand whilst manipulating a medical device in another to connect it to the component 32 supported within the support device 2. Alternatively, and advantageously, the support device 2 may be allowed to rest on a work surface, and a practitioner may simply use one hand to guide a medical device into connection with the component 32 supported by the support device 2. The particular arrangement shown promotes such operation as the component 32 is supported in a vertical manner, this means that when a practitioner comes to connect a medical device which is connected through the application of a vertical force, e.g. where the connection requires a
- 18 friction fit, any vertical force is applied through the support device 2 in a vertical manner. This helps to avoid any lateral forces on the support device 2 and thus reduces the likelihood of the support device 2 slipping across a work surface. The support device may be provided with at least one anti-slip pad (not shown) on its underside which may further help to prevent the support device 2 from slipping on a work surface.
In this particular example the component 32 is inserted into the support device 2 whilst being attached to the end of a syringe 34. However, this is not essential and the component 32 may be inserted into, and supported by, the support device 2 without any medical device being attached to it. For example, a practitioner may insert a component 32 into the support device 2 prior to carrying out a procedure such that it is already supported and presented by the support device 2 ready for a medical device to be attached as is necessary during the procedure. Figure 6 shows a close-up view from above of a representation of the hub 36, of a component 32, within the support arrangement 4. In this example the hub 36 comprises two protrusions 48 extending from opposing sides of the hub 36. In this particular example the protrusions 48 are wing-shaped. When inserted into the support arrangement 4, the hub 36 is supported and gripped in various places. Firstly, during insertion, the main body of the hub 36 displaces the tab 16. Due to the resilient nature of the tab 16, the tab provides an opposing force on the hub 36 which acts to provide a friction fit and secure the hub 36 within the support arrangement 4. Additionally, as the hub 36 is inserted, the protrusions 48 extend into the protrusion receiving portions 14b, 14e. The space provided by each of the receiving portions 14b, 14e, prior to insertion of the hub 36, is physically smaller than the width of the protrusions 48. However, the lugs 12a-d, which define the receiving portions 14a-f, are flexible and as such insertion of the hub 36 causes the lugs 12a-d12 to deform and apply a resistive force back upon the protrusions 48. This acts to provide a further frictional force gripping the hub 36.
The hub 36 has a diameter which is wider than that of the opening 24 at the base portion of the cavity 10. During insertion, this results in a portion of the hub 36, for example a rim, coming into with the rim 26. This acts as a stop which prevents the hub 36 from being advanced into the support arrangement 4 any further and also acts to help support the hub 36.
Figure 7 shows a close-up view from above of a representation of a hub 136, of another component, within the support arrangement 4. In this example the hub 136 is held in the support arrangement by a friction fit provided by the flexible tab 16 and also against the tips 50 of the lugs 12a-d which define the protrusion receiving portions 14a-f. Similarly to the example seen in Figure 6, the hub 136 comes into contact with the rim 26 at the base portion of the cavity 10.
- 19Figure 8 shows a perspective view of a support device 102 in accordance with a further embodiment of the present invention. Similarly to the first embodiment, the support device 102 comprises three support arrangements 104, spaced equiangularly around the support device 102. The support arrangements 104 are identical to the support arrangements 4 seen in the first embodiment. The support device 102 comprises three further support arrangements, a first further support arrangement 152, a second further support arrangement 154 and a third further support arrangement 156. Each of the further support arrangements 152, 154, 156 has a different dimension such that each is suitable for supporting a different device/component. Similarly to the support arrangements 104, each of the three further support arrangements 152, 154, 156 comprises its own further resilient, flexible tab 158 arranged to assist in providing a friction fit when a device/component is inserted therein.
The support device 102 further comprises indicia 160 in the form of numbers, located proximal to each support arrangement 104. These numbers may be used, for example, to guide a practitioner to which order components supported within the support arrangement 104 should be used.
In addition, the support device 102 differs from the support device 2 seen in previous Figures in that it further comprises a perimeter wall 162 which extends all the way around the support device 102. The perimeter wall 162 acts to define a well 164. As discussed previously, the well 164 may act to retain any fluid which leaks from a medical device or associated component during use. Similarly to earlier embodiments, the perimeter wall 162 may also prevent a medical device from inadvertently coming into contact with a non-aseptic surface in the instance where misconnection occurs, as discussed previously with respect to Figure 5e.
Figure 9 shows a perspective view of the underside of the support device 102. The base portion of each support arrangement 104 is essentially the same as the base portion of the support arrangement 4 seen in earlier Figures. It is apparent from this view how the further support arrangements 152, 154, 156 are in the form of open ended cylindrical holes within the support device 102 and thus do not comprise a base portion like the support arrangements 104. It is also apparent from this view how the further resilient flexible tab 158 extends axially along each further support arrangement 152, 154, 156 and how there is a space 166 provided behind each further resilient flexible tab 158. This space 166 allows the further resilient flexible tab 166 to be flexed inwards as a further device or component is inserted therein.
-20Figure 10 shows a side view of the support device 102 seen in Figures 8 and 9. The perimeter wall 162 not only defines the well 164 as seen in Figure 8, but also defines a base portion 168 which is arranged, in use, to rest on a work surface. In this particular embodiment, whilst it can only partially be seen in this Figure, the base portion comprises three legs 170 which are arranged to form a tripod. These three legs 170 may rest on a work surface and act to support the support device 102 in a stable manner.
Figure 11 shows a close-up view of a third embodiment of a support device 202. Similarly to the second embodiment, the support device 202 comprises a perimeter wall 262 that extends around the support device 202 which acts to define a well 264. The support device 202 differs from the second embodiment in that the support device 202 further comprises a plurality of drain holes 272. As will be appreciated, any liquid which is spilled onto the support device 202 will collect in the well and then will leave the support device 202 via at least one of the plurality of drain holes 272. This may be advantageous as it may allow for any spilled liquid to be removed from the support device 202, for example prior to the support device 202 being moved to a work area.
The exact number and arrangement of drain holes 272 may depend on the particular shape and configuration of the support device 202 along with its intended use. Figure 12 shows a view from above of the support device 202 seen in Figure 11.lt can be seen that the support device 202 has a generally triangular shape. In this particular embodiment three drain holes 272 are arranged at each apex 274, 276, 278 of the support device 202 and proximal to each support arrangement 204 on the support device 202.
Figure 13 shows a perspective view of a fourth embodiment of a support device 302. The support device 302 is substantially the same as the support device 202 of the third embodiment, except that each support arrangement 304 further comprises a first latch 380 and a second latch 382 arranged above the hub receiving portion 306. The latches 380, 382 may be used to positively latch onto a connection hub of a medical device component, as will be described in more detail later with respect to Figures 16a-16d. Figure 14 shows a close-up side view of the support device 302 seen in Figure 13, focussing on the support arrangement 304. In this view, only the second latch 382 can be seen, however it should be appreciated that first latch 380 is identical to the second latch 382 and is simply arranged on the opposite side of the support arrangement 304. The second latch 382 comprise an elongate arm 384 which extends into a hook portion 386 which is arranged to latch onto and engage with a hub (not shown). It is also apparent from both Figures 14 and 15 how each latch 382, 384, is aligned with a protrusion
-21 receiving portion 314e, 314b, respectively. This alignment ensures that when a hub comprising at least one protrusion is inserted into the support device 302, the protrusion is received by the protrusion receiving portions 314e, 314b, and aligned within the support device 302 such that the first and second latches 380, 382 also engage and latch onto the protrusion. Of course, the ability for the latches 380, 382 to engage with the protrusion will depend on the shape and extent of the at least one protrusion.
Figures 16a-d illustrate the insertion of a medical device component 332, hereinafter the component 332, into the support device 302. In this particular example component 332 is connected to a medical device in the form of a syringe 334. The component 332 comprises a hub 336 which comprises a first end 338 and a second end 342. Extending from the second end 340 is a fluid transfer hose 344. Similarly to earlier embodiments, the syringe 334 is connected, via its male tip 340, to the first end 338 of the hub. The component 332 is inserted into the support arrangement 304, leading with the second end 342 first, i.e. the end with the fluid transfer hose 344 extending therefrom. This can be seen in Figure 16a.
Figure 16b shows an enlarged view as the component 332 is further advanced into the support arrangement 304. It can be seen in this view how the hub 336 of the component 332 comprises a protrusion 388 in the form of a wing. The hub 336 comprises a further, identical protrusion, which cannot be seen in this Figure, arranged on the opposite side ofthe hub 336. This further protrusion can be seen in Figure 16c. The component 332 is inserted at a slight angle into the support arrangement 304 so as to avoid the latches 380, 382 and thereby allow full insertion.
Once the component 332, specifically the hub 336, has been fully inserted into the support arrangement 304, the component may be angled back towards vertical such that the hub 336 is engaged by the first and second latches 380, 382. This position can be seen in Figures 16c and 16d. Figure 16c shows a perspective view of the component 332 once fully inserted into the support device and Figure 16d shows a side view of the support device 302 with the component 332 fully inserted therein. Once fully inserted and tilted back towards vertical, the hub 336 ofthe component is further engaged by the first latch 380 and second latch 382. Specifically, the hook portion 386 of each latch engages with the protrusions 388, 390. In this particular embodiment the first and second latches 380, 382 act to engage the hub 336 and prevent upward, i.e. vertical, movement ofthe component 332. Once the hub 336, has been engaged by the support device, a practitioner may disconnect the syringe 334 by first gripping the support device 302 and subsequently applying a pulling force to the syringe 334 to separate it from the second end 338 of the hub 336. The practitioner may also apply a counter force, e.g. with a thumb or finger
-22on the hand holding the syringe 334, to push the support device 302 together with the component 332 supported therein away from the syringe 334, i.e. the disconnection may be achieved in a one-handed manner. Once disconnected, a practitioner may connect and disconnect any number of different medical devices to the component 332 throughout a medical procedure. Alternative, or in addition, the practitioner may disconnect the syringe 334 from the component 332 by turning the syringe 334 relative to the component 332. Rotation of the component 332 will be prevented at least due to the engagement of the protrusions 388, 390 in the protrusion receiving portions and also their engagement with the latches 380, 382.
In order to remove the component 332 from the support device 302, the hub 336 may be tilted away from vertical in order to bring it out of engagement with the first and second latches 380, 382, thereby allowing the component 332 to be removed from the support device 302.
Figure 17 shows a further embodiment of a support device 402. The support device 402 is essentially the same as the support device of the fourth embodiment, except that the support device 402 further holds a pierceable block 492 arranged in the centre of the support device 402. As discussed previously, the pierceable block 492 may be used as a means for storing used needle assemblies. For example, during a medical procedure, once a practitioner has finished with a needle assembly, e.g. after drawing a fluid from an ampoule, they may proceed to safely discard the used needle assembly into the pierceable block 492. This will avoid the need for the practitioner to have a sharps bin in close proximity or alternatively avoid the practitioner unsafely discarding the used needle assembly, for example onto a tray. The pierceable block 492 may be positively engaged by the support device 402 such that it cannot fall out of the support device 402, e.g. if the support device 402 is picked up by a practitioner. In this instance, it may be possible to release the pierceable block 492 from the support device, e.g. by deforming the wall of the support device 402 on the underside of the pierceable block 492. Alternatively, the pierceable block 492 may simply rest within the support device 402 and may be free to fall away from the support device 402 if the support device 402 is tilted about a sufficient angle.
Figure 18 shows a plurality of support devices 2, 2’, 2”, which are identical to those seen in Figure 1, stacked on top of one another. The cylindrical protrusion 18 of each support device 2 engages with the underside of a support device stacked thereon and assists in retaining the support devices in the stacked arrangement.
-23 In each of the embodiments discussed above, a medical device component may be inserted into, and supported by, the support device without the component being attached to a medical device. For example, a practitioner may arrange multiple medical device components within the support device prior to carrying out a procedure, such that they can easily connect medical devices whilst carrying out a procedure. Additionally, or alternatively, a practitioner may insert a medical device component into the support device whilst it is connected to a medical device, and subsequently use the support device to assist with the disconnection of the medical device from the medical device component.
