Definitions
- the present invention relates to catheter assemblies.
- the invention concerns packaged urinary catheter assemblies, and most particularly, but not exclusively packaged intermittent male urinary catheter assemblies, especially “closed” catheter assemblies.
- Intermittent catheter assemblies can provide a convenient and portable solution to this problem as a user is able to self-catheterise to relieve themselves as required. This reduces the effect of their urinary condition on their life and allows thm to enjoy a relatively normal lifestyle.
- catheter assemblies It is desirable for catheter assemblies to be compact so that they are easily portable. However, this can cause problems during use of the catheter as the components of the assembly are made smaller or are concealed within the assembly in a way that is difficult to access. This can make use of the catheter in a safe and controlled manner difficult.
- catheter assemblies are discreet such that a layperson may not identify them as a packaged catheter assembly at all. This can make a user feel more comfortable carrying and using them.
- the packaged catheter assembly must remain usable such as by providing visual feedback of the drain of fluid from the body. This can make providing a discreet packaged catheter assembly that is also easy to use difficult and so a user may decide to place the packaged catheter assembly in a dedicated bag to hide it. However, this can cause hygiene issues if the bag is not cleaned/replaced regularly and also increase the weight and bulk of the packaged catheter assembly when carried around.
- the present invention concerns a catheter assembly comprising a catheter.
- the present invention also concerns a packaged catheter assembly comprising a pouch and the catheter assembly, wherein the pouch is configured to contain the catheter assembly within it.
- a catheter assembly comprising a fluid collection bag; a catheter; and a passageway extending from the fluid collection bag.
- the passageway has an extended configuration and a stowed configuration.
- the passageway permits fluid to pass therethrough and in/out of the bag, and preferably in the stowed configuration the passageway is folded or rolled to inhibit flow of fluid therethrough.
- the passageway may extend beyond an edge of the bag.
- a catheter assembly comprising a fluid collection bag; a catheter having a proximal end for insertion into the body and a distal end; and a passageway extending from the fluid collection bag; the passageway having an extended configuration and a stowed configuration, wherein in the extended configuration the passageway extends beyond an edge of the bag and permits fluid to pass therethrough and in/out of the bag, and in the stowed configuration the passageway is folded or rolled to inhibit flow of fluid therethrough.
- the stowed and extended configurations of the passageway ensure that fluid access during use of the catheter assembly can be easily and conveniently controlled while also enabling the catheter assembly to be compact.
- This provides a better user experience.
- this separates the passageway from the bag which makes fluid flow into and out of the bag via the passageway more controllable and also reduces the likelihood of spillage of fluid onto the exterior of the bag or user - improving hygiene whilst using the assembly.
- it allows the provision of hybrid open/closed catheter assemblies that the user can use in either an open mode where fluid passes straight through and out of the catheter assembly or a closed mode where fluid is collected/retained by the catheter assembly in use.
- the stowed configuration of the passageway may be interchangeably referred to as a closed configuration.
- the extended configuration of the passageway may be interchangeably referred to as an open configuration.
- the catheter assembly may comprise more than one passageway, in which case aspects of the passageway outlined below may apply either to one of the passageways, or to more than one, for example to each passageway.

- the passageway may extend at an angle from the left or right lateral edge of the peripheral bond.
- the peripheral bond may correspond to an edge of the fluid collection bag.
- the passageway may extend at an angle of 10 to 40 degrees from an edge of the fluid collection bag.
- the passageway may extend from the fluid collection bag at the angles described above when in the extended configuration.
- fluid flow through the passageway is enhanced through the alignment of the passageway to create direct access to the central regions of the bag via the passageway and furthermore as the passageway extends away from the centre of the bag and optionally beyond two edges of the bag, it is more easily accessible and any spillage of fluid at the end of the passageway is less likely to contact the fluid collection bag/user.
- a catheter assembly comprising a catheter having a proximal end for insertion into the body and a distal end; a fluid collection bag configured to receive fluid from the catheter; and a passageway extending from the fluid collection bag; the passageway having an extended configuration and a stowed configuration, wherein in the extended configuration the passageway extends beyond an edge of the bag at an angle of 10 to 40 degrees from an edge of the bag and permits fluid to pass therethrough and in/out of the bag, and in the stowed configuration the passageway is folded or rolled to inhibit flow of fluid therethrough.

- FIG. 1-8 a first embodiment of a packaged catheter assembly 100 is shown. Those skilled in the art will immediately recognise that it is a “closed” catheter assembly, including a fluid collection bag 110.
- the assembly 100 comprises a pouch 170 with an integral fluid collection bag 110, a catheter 120, and a fluid reservoir 140.
- the catheter 120 has a proximal end 121 for insertion into the body and a distal end 122.
- the catheter 120 is a male urinary catheter made from a hydrophilic thermoplastic elastomer (TPE). Obviously those skilled in the art will be able to select suitable alternative examples.
- the pouch 170 is formed from a single rectangular piece of material.
- the pouch is formed by folding this single piece of material along a pouch fold-line spanning the width of the pouch at a point midway along its length to form a front wall 171 and a rear wall 172 of the pouch 170.
- a peripheral seal exists between the front wall 171 and rear wall 172 around the edges of the front wall 171 and rear wall 172 to form the pouch 170 and contain the contents of the pouch 170.
- the pouch fold-line forms a base edge 173a of the pouch.
- the peripheral seal forms a left lateral edge 173b, right lateral edge 173c and upper edge 173d.
- the left lateral edge 173b and right lateral edge 173c being defined as the right and left sides of the pouch 170 when viewing the pouch 170 with the rear wall 172 behind the front wall 171, the base edge 173a at the bottom of the pouch 170 and the upper edge 173d at the top of the pouch 170.
- the left lateral edge 173b, right lateral edge 173c and upper edge 173d are formed through heat sealing the front wall 171 to the second wall 172, but in other embodiments any suitable bonding may be used such as Velcro (RTM), chemical adhesives, chemical bonding, ultrasonic bonding, or mechanical bonding.
- RTM Velcro
- one or more further folds may be included, in addition to the peripheral seal. It is also conceivable that no folds may be provided.
- none of the edges may comprise a fold, one, and only one, edge may comprise a fold (as in the illustrated example), or two or more of the edges may comprise a fold.
- the peripheral seal is configured to break to allow the pouch 170 to be unfolded. Consequently, the pouch 170 has a closed configuration in which it is folded and preferably the peripheral seal is sealed, and an open configuration in which it is unfolded.
- the pouch 170 is formed from an opaque material and as such provides a discreet package for the packaged catheter assembly 100 which can make the user more comfortable in carrying the packaged catheter assembly 100 in day- to-day life.
- the exterior of the pouch 170 may have a textured or printed appearance and feel, such as a matte finish to reduce the impression that it is a medical device.
- the front wall 171 comprises a front opening tab 175 and the rear wall 172 comprises a rear opening tab 176. Both the front opening tab 175 and rear opening tab 176 project from the pouch 170 along an edge corresponding to the upper edge 173d of the peripheral seal.
- Each of the tabs 175, 176 of this particular embodiment are rectangular in shape with lateral edges 175b, 176c parallel to and continuing from a respective lateral edge of the pouch 170.
- the front opening tab 175 positioned on a left side of the pouch 170 and extends to a midpoint across the width of the pouch 170
- the rear opening tab 176 is positioned on a right side of the pouch 170 and also extends to a midpoint across the width of the pouch 170.
- each tab 175, 176 reaches the midpoint across the width of the pouch 170, each comprises a slanted edge 175d, 176d extending in overlap with the other respective tab 175, 176.
- the tabs 175, 176 are arranged at either side of the pouch 170 but with a region of overlap at the middle quarter of the width of the pouch 170.
- the tabs 175, 176 are positioned at offset but corresponding positions on the edge of the pouch 170. This helps to make it easier to grasp and separate the tabs 175, 176.
- the tabs 175, 176 may be positioned at overlapping positions with no offset to reduce the form factor of the pouch 170.
- the overlap is a preferred feature they may be arranged in other embodiments so as not to overlap.
- Each tab 175, 176 also comprises an optional gripping hole 177.
- Each gripping hole 177 of this particular example is in the shape of a stadium, that is a rectangle with semicircles replacing two opposite sides. The parallel sides of each gripping hole 177 are parallel to the upper edge 173d of the peripheral seal and form apertures which allow the user to easily grasp each tab 175, 176. Of course, alternative shapes of gripping hole can be readily imagined.
- Each gripping hole 177 is partially in overlap with the slanted edge 175d, 176d of the other respective tab 175, 176. This ensures the user can easily separate the tabs 175, 176 by pushing one tab 175, 176 away from the other through one of the respective gripping holes 177.
- the pouch 170 is initially provided in the closed configuration in which it is folded and the fluid collection bag 110, catheter 120, and fluid reservoir 140 sealed within the pouch 170 by the peripheral seal.
- the user grasps each of the tabs 175, 176 using the gripping holes 177 and pulls the tabs 175, 176 away from one another.
- This pulls the front wall 171 away from the rear wall 172 and breaks the peripheral seal namely breaking a frangible portion of the seal which comprises all of the edges 173b, 173c, 173d of the peripheral seal.
- the pouch fold-line on the other hand is not frangible, and represents a permanent join between the front wall 171 and the rear wall 172.
- the pouch 170 is therefore configured to be moved from the closed configuration to the open configuration in which it is flat and unfolded.
- the fold along the base 173 a of the pouch is no longer present and as such the front and rear walls 171, 172 of the pouch 170 are adjacent to one another and combine to form a single flat rectangular piece of material.
- the locations on the front and rear walls 171, 172 where the left and right lateral edges 173b, 173c of the peripheral seal previously sealed the walls 171, 172 define the left and right lateral edges 173b, 173c of the open pouch 170 respectively.
- the location in which the upper edge 173d previously sealed the rear wall 172 forms the top of the open pouch 170 and the location in which the upper edge 173d previously sealed the front wall 172 forms the bottom of the open pouch 170.
- the front wall 171 further comprises a wetting marker 178 disposed on an external face of the pouch 170 (i.e. on the front wall 171) is in the closed configuration and further at a position corresponding to the fluid reservoir 140 in the pouch 170.
- the wetting marker 178 may be disposed on the rear wall 172 or on both the front and rear walls 171, 172.
- the wetting marker 178 is configured to provide a tactile and/or visual guide to allow the user to activate the fluid reservoir 140 to release wetting fluid into the fluid collection bag 110 as described below.
- the wetting marker 178 comprises a region of the front wall 171 that is a different colour from the rest of the front wall 171.
- the wetting marker 178 may be a pattern or logo, or may provide tactile feedback by comprising a raised area or different texture to the rest of the front wall 171.
- the wetting marker 178 may be positioned on the rear wall 172 or there may be two or more wetting markers 178 placed on the front and/or rear walls 171, 172.
- the fluid collection bag 110 is arranged to receive fluid from the distal end 122 of the catheter 120.
- the fluid collection bag 110 comprises a front panel 111, a rear panel (not shown) of identical shape and size to the front panel 111, and a peripheral bond joining the periphery of the panels to form the bag 110.
- the front and rear panels are sized to fit within the area enclosed by the lateral edges 173b, 173c and upper edge 173d of the peripheral seal of the pouch 170 in its open configuration.
- the front and rear panels may be sized differently according to the needs of the user, for example they may be sized to be larger than the front and/or rear walls 171, 172.
- the rear panel is bonded to the pouch 170 at points corresponding to the front and rear walls 171, 172 such that the fluid collection bag 110 is within the pouch 170 when the pouch 170 is in the closed configuration and fixed to the pouch 170 when the pouch 170 is in the open configuration.
- the fluid collection bag 110 may only be bonded to the front wall 171 or rear wall 172, or may not be bonded to the pouch 170 at all.
- the front and rear walls 171, 172 of the pouch 170 may themselves form the rear panel.
- the peripheral bond defines a base 112, a right lateral edge 113, a left lateral edge 114 and an upper edge 115 of the bag 110.
- the base 112 of the bag 110 corresponding to the end of the bag 110 closest to the position of the upper edge 173d of the peripheral seal of the pouch 170 on its front wall 171.
- the right lateral edge 113 and left lateral edge 114 of the bag 110 corresponding to the left and right lateral edges 173c, 173d of the pouch 170.
- the upper edge 115 of the bag 110 corresponding to the end of the bag 110 closest to the position of the upper edge 173d of the peripheral seal of the pouch 170 on its rear wall 171.
- the peripheral bond thus defines a bag 110 that is generally rectangular and suitably has a width between the lateral edges of between 10 and 20 cm, and most preferably between 12 and 15 cm between 60-110 mm, for example about 100mm, e.g. 95 mm, and a height from the base 112 to the upper edge 115 of between 25 and 40 cm, 30 and 35 cm, or most preferably 33 and 35 cm.100 to 250 mm, for example about 200 mm, e.g. 197 mm.
- the bag is thus configured to hold at least 700 ml of fluid released from the user through the catheter safely.
- the base 112 defines the bottom of the bag 110 in use, and the upper edge 115 the top.
- alternative shapes and sizes could be conceived, such as elliptical or circular panels forming correspondingly shaped bags, or even a tubular bag or bag with more than two panels, e.g. a prism or other polygon.
- the panels comprise a flexible plastics material, for example polypropylene (PP), polyethylene terephthalate (PET), low density polyethylene (LDPE), metalized polyester (MET PET), orientated polypropylene (OPP) or polyvinyl chloride (PVC).
- PP polypropylene
- PET polyethylene terephthalate
- LDPE low density polyethylene
- MET PET metalized polyester
- OPP orientated polypropylene
- PVC polyvinyl chloride
- the panels are preferably transparent, but may be translucent. In other embodiments the panels may be opaque. In particular, the front panel 111 may be transparent/translucent, but the rear panel opaque.
- the fluid collection bag 110 as described above overlies a majority of the pouch 170 when the pouch 170 is in the open configuration.
- the pouch 170 may therefore be held in its open configuration with the front/rear walls 171, 172 forming a single bottom layer, then the rear panel of the fluid collection bag 110 and finally the front panel 111 of the fluid collection bag 110 forming a top layer.
- the fluid collection bag 110 is similarly folded along a fold-line corresponding to the pouch fold-line and base 173a of the pouch 170.
- the base 112 of peripheral bond of the fluid collection bag 110 and upper edge 115 of the peripheral bond of the fluid collection bag 110 are consequently adjacent to one another as well as the upper edge 173d of the peripheral seal of the pouch 170.
- the fluid collection bag 110 comprises two passageways: a neck 150 and a drain 160. Both the neck 150 and drain 160 are formed internally with the fluid collection bag and extend from the fluid collection bag 110. They are each movable between a stowed (closed) configuration and an extended (open) configuration as described below.
- the fluid collection bag may only comprise one passageway or more than two passageways, and each passageway may have a function as required by the bag 110.
- a fluid collection bag may have only comprise one passageway that fulfils the role of the neck and drain described in the illustrated embodiment.
- the upper edge 115 of the bag 110 comprises the neck 150 which spans approximately 25% of the length of the upper edge 115 from the left lateral edge 114. In other embodiments, it may be located a different point on the upper edge 115 or peripheral bond, such as on the left or right lateral edges 114, 113, or base 112, and may have a different size in relation to the rest of the bag 110 or edge in which it is situated.
- the neck 150 is elongate and tubular having a length approximately equal to a third of the height of the pouch 170 in the open configuration. The height of the pouch 170 in the open configuration being defined as the distance between the upper edge 173d adjacent the front opening tab 175 and the upper edge 173d adjacent the rear opening tab 176 taken parallel to the left lateral edge 173b of the pouch 170.
- the neck 150 comprises a proximal end 151 distal from the bag 110 configured to allow the proximal end 121 of the catheter 120 to pass through it and out of the bag 110.
- the proximal end 151 of the neck 150 comprises a cylindrical plug 152 that is push-fit into a socket at the proximal end 151 of the neck 150 to prevent the catheter 120 leaving the bag 110 unintentionally.
- the plug 152 also seals the proximal end 151 of the neck 150 to prevent unintentional passage of fluids into/out of the bag 110.
- the plug 152 has a domed end and also comprises a pull-ring 153 integral with the dome of the plug 152. The plug 152 may therefore be easily removed from the neck 150 by pulling the pull-ring 153 away from the bag 110.
- the neck 150 also comprises a guide tube 154 extending from the proximal end 151 towards the fluid collection bag 110 and within the neck 150.
- the guide tube 154 is cylindrical with a smaller radius than the neck 150.
- the guide tube 154 comprises an aperture therethrough sized to allow the catheter 120 to pass through the tube 154 and proximal end 151 of the neck 150.
- the proximal end 151 of the neck 150 comprises an optional catheter locater tip configured to allow the proximal end 121 of the catheter 120 to be easily located by the user prior to use. This allows the user to more easily use the catheter 120 as the tip can be more easily located and inserted into the body through use of the neck 150.
- the neck 150 extends away from a central region of the bag 110 at an angle of 20 to 30 degrees from an angle parallel to the left lateral edge 114 of the bag 110, preferably at an angle of 23 degrees. As such, the neck 150 is angled towards the centre of the bag 110 to allow the catheter 120 and/or fluids more easy access to the bag 110 without sharp turns/folds of the bag 110 or neck 150 obstructing fluid flow.
- the base 112 of the bag 110 comprises the drain 160 which spans 25% of the length of the base 112 of the bag 110 from the right lateral edge 113 of the bag 110.
- the drain 160 may be located a different point on the base 112 or peripheral bond, such as on the left or right lateral edges 114, 113, or upper edge 115, and may have a different size in relation to the rest of the bag 110 or edge in which it is situated.
- the drain 160 is a similar shape and size to the neck 150 and is elongate and tubular, however, it has a length approximately half that of the neck 150.
- the drain 160 also extends away from the bag 110 in a direction parallel to the angle the neck 150 extends but in the opposite direction and as such also extends away from a central region of the bag.
- the drain 160 comprises a distal end 161 distal from the bag 110.
- the distal end 161 is open-ended and as such can provide a conduit for fluids to pass out of the bag 110.
- the drain 160 may be closed, for example having a tear-off end to open it.
- the base 112 of the bag 110 is sloped between the left lateral edge 114 of the bag 110 and drain 160 such that fluid more easily flows from the bag 110 to the drain 160 if required.
- the base 112 of the bag 110 is sloped at an angle of 70 to 80 degrees with respect to the left lateral edge 114 of the bag 110 and most preferably 74 degrees.
- this funnels liquid in the bag 110 towards the drain and balances the needs of allowing fluid to easily flow from the bag 110 whilst maintaining the internal volume of the bag 110.
- the neck 150 and drain 160 are movable between respective extended (open) and stowed (closed) configurations.
- the neck 150 is configured to be folded at the point it meets the bag 110 along a neck fold-line 155 that is perpendicular to the direction the neck 150 extends away from the bag 110.
- the neck fold-line 155 therefore truncates the corner of the bag 110 between the left lateral edge 114 and upper edge 115 of the bag 110.
- the drain 160 is configured to be folded along a drain fold-line 162.
- the drain fold-line 162 is at the same angle as the neck fold-line 155 and truncates the comer of the bag 110 between the right lateral edge 114 and base 112.
- the neck 150 and drain 160 have open configurations in which they are unfolded and extend away from the bag 110 as described above. As they extend at an angle, the proximal end 151 of the neck 150 is positioned to the left of the left lateral edge 114 and above the upper edge 115 of the bag 110 in the open configuration. Similarly, the distal end 161 of the drain 160 is positioned to the right of the right lateral edge 113 and below the base 112 of the bag 110 in the open configuration. This helps to ensure that the ends of the neck/drain are more easily accessible and that any leakage of fluid from them is less likely to spill onto the pouch 170 or fluid collection bag 110. Of course, in other embodiments where the neck 150 and drain 160 may extend at different angles or from different edges of the bag 110, they may extend to be in different positions while still realising the benefits of the invention.
- the neck 150 and drain 160 are folded about the neck fold-line 155 and drain fold-line 162 respectively such that they lie on the front panel 111 of the bag 110.
- the neck 150 and drain 160 extend into a central region of the bag 110 from their respective corners of the bag 160.
- the bag 110 further comprises a closure flap 116 disposed on, and attached to, the front panel 111.
- the closure flap 116 is rectangular with rounded comers and an aspect ratio (width: length) of approximately 1:2.
- the width of the closure 116 is aligned with and parallel to the drain fold-line 162 and the closure 116 spaced from the drain fold-line 162 in a direction perpendicular to the drain foldline 162 and by a distance approximately equal to a third of the length of the drain 160. As such, approximately two-thirds of the drain 160 in its folded configuration overlaps with the closure 116.
- one side of the closure flap 116 is adhesive.
- An upper quarter of the flap 116 that is the quarter furthest from the drain fold-line 162, is permanently adhered to the front panel 111.
- the remaining three quarters of the flap 116 comprises a re- sealable adhesive that is configured to seal to the drain 160 between the flap 116 and front panel 111 of the bag 110 and retain the drain 160 in its closed configuration.
- permanent adherence of the flap 116 to the front panel 111 of the bag 110 is achieved through welding but in other embodiments any suitable sealing method may be used as described elsewhere in this disclosure.
- any suitable re-sealable or temporary adhesive means may be used such as hook-and-hook or hook-and-loop, chemical adhesives, magnetism, etc.
- the closure flap 116 firmly holds the drain 160 in its initial stowed/closed position, maintaining a tight fold that is intended to prevent liquid entering the drain in its stowed/closed position. Moreover, the adhesive flap covers the entire open end of the drain, sticking it to the panel and closing it off, thus further inhibiting leakage in the unlikely event that fluid passes the fold into the drain 160.
- a lower half of the flap 116 that is the half closest to the drain fold-line 162, comprises a finger hole 117.
- the finger hole 117 is rectangular and is configured to allow the user to better grip the flap 116 to remove the flap 116 from the drain 160 allowing the drain 160 to be moved from its closed configuration to its open configuration.
- the flap 116 may comprise an alternative to the finger hole 117 such as ridges or another easily gripped element to facilitate removal of the flap 116 from the drain 160.
- the flap 116 may be replaced with any suitable means for retaining the drain 160 in the closed configuration.
- the drain 160 itself may adhere to the front panel 111 through a flap or other similar feature permanently attached to the drain 160.
- the front panel 111 may comprise a retaining slot which the drain 160 can be fed within to retain it in the closed configuration.
- the fluid reservoir 140 is a rectangular sachet which contains wetting fluid.
- the fluid reservoir 140 has a length equivalent to approximately three quarters the separation distance between the left and right lateral edges 114, 113 of the bag 110 and a width approximately one third its length. In other embodiments, different sizes or shapes of fluid reservoir 140 may be used as required.
- the fluid reservoir 140 comprises an activation marker 144 on its surface.
- the activation marker 144 comprises a region of the fluid reservoir 140 that is identifiable to the user for example through visual and/or tactile feedback in an equivalent manner to the wetting marker 178 described above.
- the activation marker 144 is at least visually recognisable and a different colour, or pattern, to the fluid reservoir 140.
- the fluid reservoir 140 is positioned inside the fluid collection bag 110 at the corner where the upper edge 115 and right lateral edge 113 meet. The length of the fluid reservoir 140 is aligned parallel to the upper edge 115 and as such, the neck 150 is at one end of the fluid reservoir 140 and the right lateral edge 113 at the other.
- the fluid reservoir 140 may be positioned at different points within the bag 110 or pouch 170, or may be external from the bag 110 and/or pouch 170 as required.
- the fluid reservoir 140 is retained in this position by a join
- the join 142 between the front and rear panels of the bag 110.
- the join 142 is separated from the upper edge 115 of the bag 110 by a distance approximately equal to the width of the fluid reservoir.
- the join 142 is further positioned approximately one third of the way from the left lateral edge 114 to the right lateral edge 113 of the bag.
- the join 142 is generally elliptical in shape with a major axis aligned with the length of the fluid reservoir 140 and an aspect ratio (width: length) of 1:3.
- the join 142 may be different shapes for example circular or rectangular, and may be positioned in different places within the bag 110.
- the fluid reservoir 140 is further retained by a protrusion
- the protrusion 143 in the peripheral bond of the bag 110.
- the protrusion 143 extends from the right lateral edge 113 of the bag 110 at a point separated from the upper edge 115 of the bag 110 by a distance equal to the width of the fluid reservoir 140.
- the protrusion 143 is rectangular with a length and width in directions parallel to the length and width of the fluid reservoir 140.
- the protrusion 13 has a width approximately the same as the minor axis of the join 143, and an aspect ratio (width: length) of 1:2.
- the join 142 and protrusion 143 together retain the fluid reservoir 140 in position adjacent to the upper edge 115 and right lateral edge 113 of the bag 110.
- the protrusion 143 may have a different size and shape to suit the configuration and features of the catheter assembly such as the size/shape of the fluid reservoir 140 or fluid collection bag 110.
- the wetting fluid is water and interacts with the hydrophilic surface of the catheter 120 to render it lubricious.
- other wetting fluids may be used and they may be polar (e.g. water-based) or non-polar (e.g. oilbased) depending on the catheter’s surface properties.
- the catheter 120 is positioned in the bag 110 with the proximal end 121 of the catheter 120 retained within the guide tube 154 of the neck 150.
- the catheter 120 then extends along the neck 150 and adjacent to the upper edge 115 of the bag 110 before passing over the fluid reservoir 140 and between the join 142 and protrusion 143.
- the catheter 120 then curves towards the drain 160 and the distal end 122 of the catheter 120 is positioned adjacent the drain fold-line 162 and beneath the closure flap 116.
- the catheter 120 is therefore free to move within the fluid collection bag 110 except for the portion of the catheter 120 positioned between the join 142 and upper edge 115 of the bag 110 and the portion of the catheter 120 retained within the tube 154 of the neck 150.
- the catheter 120 may be positioned differently, for example it may be partially or completely outside the bag 110 and even partially outside the pouch 170.
- the catheter 120 comprises a funnel 123 at its distal end
- the catheter 120 may not comprise a funnel 123 and/or may comprise a different type of handling element at its distal end 122.
- the catheter 120 is configured to pass through the guide tube 154 and out of the distal end 151 of the neck 150.
- the funnel 123 is not configured to pass through the guide tube 154, but rather, when the catheter 120 is pulled out, the proximal end of the funnel is a tight fit in the guide tube and as such prevents separation of the catheter 120 from the bag 110 and ensures that fluid within the catheter 120 always passes into the bag 110 and does not escape through the guide tube 154.
- the catheter 120 may be completely removable from the bag 110, for example the catheter 120 may not comprise a funnel
- the proximal end 121 of the catheter 120 is retained in the tube 154 which prevents the proximal end 121 from falling into the inside of the bag 110. This ensures the catheter 120 is easy to feed through the neck 150 and out of the bag 110 as the proximal end 121 of the catheter 120 need not be lined up with the guide tube 154 which may be difficult especially for a user with reduced mobility.
- the proximal end 121 may not be retained in a guide tube 154 and may be removable from the guide tube 154 or positioned in a different point in the bag.
- the curvature and position of the catheter 120 as described above is engineered to reduce the risk of damage and kinks to the catheter 120 when stored within the pouch 170.
- the neck 150 is folded against the front panel 111 of the bag 110 at the neck fold-line 155.
- the catheter 120 is curved so that the tangent angle of the catheter 120 at the neck fold-line 155 is parallel to the neck fold-line 155.
- the curvature of the catheter 120 between the join 142 and drain 160 ensures that the tangent angle of the catheter 120 at a position in the bag 110 corresponding to the pouch fold-line/base 173a of the pouch is parallel to the pouch fold-line/base 173a.
- the degree of curvature of the catheter 120 is reduced as it passes out of the folded neck 150 and through the bag 110 when the neck 150 and/or pouch 170 are in the closed configuration.
- the packaged catheter assembly 100 is initially provided with the pouch 170 in its closed configuration and the peripheral seal containing the fluid collection bag 110, catheter 120, and fluid reservoir 140 within the pouch 170.
- the peripheral seal need not provide a sterile seal as the fluid collection bag 110 can provide a sterile environment for the catheter 120. This can make the packaged catheter assembly 100 cheaper and easier to manufacture especially where the peripheral seal is configured to be breakable.
- the peripheral bond of the fluid collection bag 110 may not provide a sterile seal and the peripheral seal of the pouch 170 may provide a sterile seal.
- both the peripheral bond and peripheral seal may provide a sterile seal which can provide extra assurance that the catheter 120 remains sterile prior to use.
- the catheter 120 may be withdrawn from the packaged catheter assembly 100 for use by first opening the pouch 170.
- the user grasps the tabs 175, 176 and pulls them apart to separate the front and rear walls 171, 172 of the pouch 170 and create an opening in the peripheral seal.
- the user continues to separate the tabs 175, 176 and front and rear walls 171, 172 until the pouch 170 is completely unfolded and the front panel 111 of the fluid collection bag 110 is exposed.
- the base 173a of the peripheral seal is configured to deform plastically which ensures the pouch 170 remains in the flat and opened configuration.
- the front panel 111 of the fluid collection bag 110 was previously contained within the sealed pouch 170, it can now present a flat and clean surface for the user. This makes use of the catheter 120 easier as parts of the assembly 100 may be placed on the opened pouch 170 as required without them being potentially contaminated with dirt.
- the neck 150 is initially provided in its closed configuration and folded against the front panel 111 of the fluid collection bag 110. The user may therefore unfold the neck 150 and move it into its open configuration. This may allow the catheter 120, which is retained by the tube 154 of the neck 150 at the proximal end 121 of the catheter 120, to be more effectively wetted by the wetting fluid released by the fluid reservoir 140 as described below.
- the fluid reservoir 140 is configured to release the wetting fluid contained within it.
- the user can release the wetting fluid by applying pressure to the fluid reservoir 140, such as between the activation marker 144 and wetting marker 178, to create a tear 141 in the fluid reservoir 140 allowing the wetting fluid to pass out of the reservoir 140 and into the fluid collection bag 110.
- the wetting fluid may be released from the fluid reservoir 140 in a different way such as by activating an opening mechanism of the fluid reservoir 140.
- the wetting fluid passes out the tear 141 in the fluid reservoir 140 and into the fluid collection bag 110 where it comes into contact with the catheter 120 and activates the surface of the catheter 120.
- the wetting fluid is contained within the fluid collection bag 110 as the plug 152 prevents it from leaving via the neck 150, and the drain 160 is in the closed configuration which prevents fluids from leaving the bag 110 therethrough.
- the fluid reservoir 140 is located close to the neck 150 and proximal end 121 of the catheter 120 and as such, wetting fluid may preferentially wet the catheter adjacent to and at its proximal end before the rest of the catheter 120. This ensures that the part of the catheter 120 that enters the body first is adequately wetted which reduces the risk of injury and discomfort during use of the catheter 120.
- the wetting fluid may flow towards the entrance of the drain 160 and collect in a pool of wetting fluid 1. If this occurs, it can be necessary to vary the orientation of the packaged catheter assembly 100, for example by rotating it such that the neck 150 is below the drain 160, such that the wetting fluid forms a pool 1 at the neck 150.
- the close fit between the catheter 120 and the tube 154 prevents inadvertent passage of fluid between the catheter 120 and tube 154 and out of the bag 110. This ensures that the proximal end 121 of the catheter 120 is adequately wetted prior to use.
- the steps of opening the pouch 170 and releasing wetting fluid from the fluid reservoir 140 may of course be performed in any order as desired by the user.
- the wetting marker 178 described above may be used to locate and activate the fluid reservoir 140 when the pouch 170 is in the closed configuration. Release of the wetting fluid into the fluid collection bag 110 prior to opening of the pouch 170 may be desirable as the fold in the pouch 170 can reduce the likelihood that the wetting fluid passes towards the drain 160 and distal end 122 of the catheter 120 before the proximal end 121 of the catheter 120 has been adequately wetted.
- the drain 160 may be moved to its open configuration by using the finger hole 117 to peel the flap 116 off the drain 160.
- the drain 160 may then be unfolded into its open configuration and fluid may then exit the fluid collection bag 110 through the drain 160. This may be done after urine has been released into the pouch, or, in the event that it is desired to immediately pass urine into a lavatory or the like, it may be done prior to releasing urine.
- the catheter 120 may be withdrawn from the pouch 170 by user grasping the neck 150 of the pouch 170 in one hand and the plug 152/pull-ring 153 in the other and then pulling the plug 152 out of the end of the neck 151.
- the catheter 120 may then be passed out of the neck 150 by feeding it through the neck 150 and tube 154.
- the proximal end 121 of the catheter 120 is retained in the tube 154 through a push-fit fitting, this removes the need for the user to carefully align the proximal end 121 of the catheter 120 with the tube 154. It also ensures that excess wetting fluid does not pass out of the fluid collection bag 110 where it could cause discomfort and inconvenience for the user.
- the user can then progressively pass more of the catheter 120 out of bag 110 and insert the proximal end 121 of the catheter 120 into the body. Once the catheter 120 has been sufficiently inserted into the body, fluid may pass out of the body through the catheter 120 and into the fluid collection bag 110 via the funnel 123.
- the packaged catheter assembly 100 is configured as an open system in which fluid entering the fluid collection bag 110 from the body and catheter 120 passes straight out of the bag 110 via the drain 160.
- the packaged catheter assembly is a closed system and can be used as such, simply by omitting the step of opening the drain 160 mentioned above prior to inserting the catheter into the body. Fluid is then prevented from leaving the bag 110 via the drain 160 and collects within the fluid collection bag 110. This can be useful where immediate disposal of the fluid from the body is not possible.
- the user may wish to empty the contents of the fluid collection bag 110 to reduce the size and weight of the used bag 110 and/or to dispose of the bag 110.
- the drain 160 may be opened to allow fluid to leave the bag 110 as described above.
- the packaged catheter assembly 100 may be used as either an open or closed system as required by the user.
- the catheter 120 and fluid collection bag 110 may be repackaged within the pouch 170. This may be possible in embodiments where the peripheral seal is configured to be re-sealable. The process for this is generally reverse of the opening procedure described above.
- the catheter 120 can be drawn back within the fluid collection bag 110 by manipulating the funnel 123 and without the need to touch the surface of the catheter 120 which may be unhygienic after use.
- the neck 150 may be resealed by re-inserting the plug 152 into the proximal end 151 of the neck 150. The neck 150 can then be re-folded such that it no longer extends out from the pouch 170.
- the drain 160 can be re-folded and sealed using the flap 116 in embodiments where the flap 116 is configured to provide a re-sealable seal.
- the flap has been opened, handling and re-folding of it may not be considered hygienic and so this step may be avoided at user-discretion.
- the pouch 170 may be closed by bringing, the tabs 175, 176 towards each other, resulting in folding of the pouch 170 about the pouch fold-line and base 173a and the bringing together of the front wall 171 and rear wall 172.
- the peripheral seal may then be re-sealed closed, for example by pressing the front wall 171 and rear wall 172 together.
- the pouch 170 may be closed without the user needing to touch the interior surfaces of the pouch 170 which may have become dirty or soiled during use of the catheter 120.
- FIG. 9 to 14 a second embodiment of a packaged catheter assembly 200 is shown.
- the second embodiment shares many of the features of the first embodiment described above, and so only differences in the features are described below, and like numerals are used to denote like features unless described differently below.
- the closed pouch 270 comprises a width between the left lateral edge 273b and right lateral edge 273c of 120-170 mm, preferably 140-150 mm, for example 146 mm.
- the closed pouch 270 comprises a height between the base edge 273a and upper edge 273d of 50-110 mm, preferably 80-90 mm, for example 86 mm.
- These sizes make the packaged catheter assembly 200 more discreet for the user and also easier to fit in a bag or pocket.
- Each of the front wall 271 and rear wall 272 of the pouch 270 have the same dimensions as the closed pouch. Consequently, when unfolded and opened, the pouch 270 has a width as described above and a height that is double the height of the folded configuration, i.e. 100-220 mm, or preferably 160- 180 mm and most preferably 172 mm.
- the features of the invention apply equally to embodiments of other sizes and shapes.
- the pouch 270 comprises a single opening tab 275 arranged on the front wall 271 of the pouch 270 (rather than the two opening tabs of the first embodiment).
- the tab 275 folds down to overlie the rear wall 272 and seal against it.
- the tab 275 and/or rear wall 272 may comprise any suitable bonding to seal the tab 275 to the rear wall 272 in a releasable manner such as Velcro (RTM), chemical adhesives, chemical bonding, ultrasonic bonding, or mechanical bonding.
- the opening tab 275 comprises a rectangular protrusion in the central quarter of the upper edge 273d on the front wall 271.
- the end of the opening tab 275 distal from the upper edge 273d is semi-circular.
- the length of the opening tab 275 from where it meets the front wall 271 to the tip of its semi-circular end is equal to its width, that is a quarter the width of the pouch 270.
- the opening tab 275 could be any suitable size or shape, for example the size/shape of the tabs of the first embodiment.
- the opening tab 275 may comprise a triangular tab spanning the entire width of the pouch 270, thus the closed pouch 270 may have the appearance of a closed envelope.
- the tab 275 comprises an tab marker 277 comprising an arrow printed onto the tab 275. The tab marker 277 points in the direction which the user should open the tab 275 in order to open the pouch 270.
- the fluid collection bag 210 is configured to be opened into an upside-down configuration wherein the neck 250 is arranged at a bottom of the fluid collection bag 210 - for example as shown in Figures 9-13. Consequently, numerals denoting the left and right lateral edges of the pouch 270 and fluid collection bag 210 are shown on the right and left sides respectively in Figures 9-13, and in these Figures the base 212 and upper edge 215 of the fluid collection bag 210 are shown at the top and bottom respectively.
- the opening of the fluid collection bag 210 in this way removes the need for the user to rotate the fluid collection bag 210 to ensure wetting fluid can access the neck 250, as required in the first embodiment above.
- the fluid collection bag 210 may then be rotated to a configuration in which the neck 250 is arranged at the top of the fluid collection bag 210 for use, as described below in more detail below.
- the fluid collection bag 210 has a width between the left lateral edge 213 and right lateral edge 214 of the fluid collection bag 210 that is approximately 3-10 mm smaller than the width of the pouch 270, for example between 100-170 mm, preferably 120-150 mm, for example 140 mm.
- the fluid collection bag 210 has a height between the base 212 and upper edge 215 of the fluid collection bag 210 of 150-350 mm, preferably 200-300 mm, for example 280 mm.
- the fluid collection bag 210 therefore has a height that is greater than the height of the unfolded pouch 270.
- the fluid collection bag 210 is split into three equally sized sections along its length.
- a first section is defined between the base 212 and a bag fold line 218.
- the bag fold line 218 spanning the width of the fluid collection bag 210 at a point approximately one third of the way from the base 212 to the upper edge 215 of the fluid collection bag 210.
- a second section is defined between the bag fold line 218 and the position of the pouch fold line which corresponds to the position of the base 273a of the closed pouch 270 when the pouch is unfolded and open.
- a third section is defined between the pouch fold line or base 273a of the pouch 270 and the upper edge 215 of the fluid collection bag 210.
- the fluid collection bag 210 may be split into 4 or more sections, or 2 sections, as required.
- each of the sections may have different sizes as required by the circumstances.
- the second and third sections of the fluid collection bag 210 are attached to the front wall 271 and rear wall 272 of the pouch 270 respectively, for example as described above in relation to the first embodiment.
- the second and third sections therefore lie completely within the peripheral seal of the pouch 270.
- the first section of the fluid collection bag 210 is not attached to the pouch 270 and is therefore free to pivot about the bag fold line 218 between a stowed configuration in which the fluid collection bag 210 is folded at the bag fold line 218 and the first section overlies the second section, and an open or unfolded configuration in which the fluid collection bag 210 is not folded at the bag fold line 218.
- the first section therefore extends beyond the edge of the pouch 270 and over the opening tab 275.
- only one section may be joined to the pouch 270 and the other two (or more) may be free to pivot/fold as required.
- all sections of the fluid collection bag 210 may be attached to the pouch 270.
- the position of the neck 250 and drain 260 are the same as in the first embodiment and further, both the drain 260 and neck 250 extend away from the fluid collection bag 210 at the same angle as described in relation to the first embodiment.
- the neck 250 has a width of between 10-30% the width of the fluid collection bag 210, for example 20%.
- the drain 260 has a width of between 15-35% of the fluid collection bag 210, for example 25%.
- the neck 250 has a length of 30-60% of the height of the fluid collection bag 210, for example 45%, or most preferably a length equal to the width of the fluid collection bag 210.
- the drain 260 has a length of approximately half the neck 250, as with the first embodiment.
- the neck-fold line 255 is angled with respect to the base 212 of the fluid collection bag 210 by an angle of 50-80 degrees, preferably 60-70 degrees, for example 63 degrees.
- the neck 250 is angled with respect to the left lateral edge 214 such that when folded about the neck-fold line 255, the neck 250 lies parallel to the upper edge 215. Consequently, the neck 250 in the stowed configuration spans across the width of the fluid collection bag 250 along its upper edge 215.
- the neck 250 does not comprise the plug or guide tube of the first embodiment.
- the neck 250 comprises a distal end 151 which comprises a small aperture 254 which is configured to allow the catheter 220 to pass out of the fluid collection bag 210.
- the fluid collection bag 220 comprises a closure 216 that replaces the closure flap of the first embodiment.
- the closure 216 is configured to retain the drain 260 in the stowed configuration.
- the closure 216 is a layer of material permanently adhered to the fluid collection bag 210 on one side, the other side comprising a resealable adhesive, for example Velcro (RTM), that can be temporarily sealed to a corresponding closure (not shown) on the drain 260, for example positioned on a side of the drain 260 corresponding to the rear panel 211a of the fluid collection bag 210.
- a resealable adhesive for example Velcro (RTM)
- the closure 216 is stadium shaped (rectangular with semi-circular ends), with a length equal to a third of the width of the drain 260 and aligned parallel to the width of the drain and an aspect ratio (length: width) of 3 : 1.
- the closure 216 may have a different size or shape as required.
- the drain 260 further comprises a pair of pursing strips, one pursing strip 266 arranged on the front panel 21 lb of the fluid collection bag 210 and a second pursing strip (not shown) arranged in a corresponding position on the rear panel 211a of the fluid collection bag 210.
- Each pursing strip in the pair is identical and comprises a more rigid material than the drain 260, for example high density polyethylene (HDPE).
- the pursing strips are configured such that in the absence of user-input they are both flat and therefore urge the two opposing panels of the drain towards one another, keeping it closed, but also allow the user to more easily separate the respective sides of the drain 260 to ensure that fluid can flow more easily out of the fluid collection bag 210 through the drain 260.
- Each pursing strip 266 is positioned half way down the length of the drain 260. Along a proximal edge of each pursing strip 266 proximal to the drain fold line 262, each pursing strip 266 spans the entire width of the drain 260 between the peripheral seal that defines the drain 260. The central half of the width of each pursing strip 266 is approximately double the thickness of its edges. Between its edges and the central half of the width, each pursing strip 266 comprises a tapered region with a convex quarter circle shape. Each pursing strip 266 spans 10 to 20% of the length of the drain 260.
- the two pursing strips flex along their length and across the width of the drain 260 and separate the front and rear panels which make up the drain 260.
- the pursing strips may have a different shape or size.
- the section of the drain 260 adjacent to the drain fold line 262 comprises an opening marker 267 on its surface corresponding to the rear panel 211a of the fluid collection bag 210.
- the opening marker 267 comprises an arrow pointing in a direction towards the drain fold line 262.
- the opening marker 267 is visible to the user when the drain 260 is in the stowed configuration and guides them in opening the drain 260.
- the opening marker 267 may of course have a different shape or be positioned differently, for example on the front panel 211b of the fluid collection bag 210 adjacent to the stowed drain 260.
- the fluid reservoir 240 is similarly shaped and sized compared to the first embodiment, however, it comprises rounded ends and is thus stadium shaped.
- the fluid reservoir 240 comprises two circular activation markers 244: one positioned at each end of the fluid reservoir 240 and each comprising the word “PRESS” on it.
- the fluid reservoir 240 is configured to rupture when activated and a tear 241 is created in the fluid reservoir 240 allowing wetting fluid to be released into the fluid collection bag 210.
- the fluid reservoir 240 is configured to rupture when activated by either of the activation markers 244 individually or when both are pressed simultaneously. This provides greater flexibility to the user. In other embodiments, the fluid reservoir 240 may only rupture when both are activated, this could help prevent premature release of wetting fluid.
- the fluid reservoir 240 is positioned equidistant between the left lateral edge 214 and right lateral edge 213 of the fluid collection bag 210 and also equidistant between the base 212 of the fluid collection bag 210 and the pouch fold line/base 273a of the pouch 270.
- the fluid reservoir 240 is positioned centrally in the third section of the fluid collection bag 240 described above.
- the fluid collection bag 210 comprises a fold line 242 between the front and rear panels 21 lb, 21 la of the fluid collection bag 210 configured to partially block fluid flow between the third and second sections of the fluid collection bag 210 when folded.
- the fold line 242 is positioned along the pouch fold line/base 273a of the pouch 270 and on the side of it closest to the upper edge 215 of the fluid collection bag 210.
- the catheter 220 is arranged with its proximal end 221 inside the neck 250 at the distal end 251 of the neck 250.
- the catheter 220 extends through the neck 250 and then into a curved and coiled around the fluid reservoir 240.
- the catheter 220 curves in an anti-clockwise direction (when viewed through the front panel 211b of the fluid collection bag 210), exiting the neck 250 and passing adjacent the left lateral edge 214 of the fluid collection bag 210. It then turns left and passes between the fluid reservoir 240 and the fold line 242 before turning left again and passing down adjacent to the right lateral edge 213 of the fluid collection bag 210.
- the catheter 220 then turns to pass between the fluid reservoir 240 and the upper edge 215 of the fluid collection bag 210 before finally turning left round the end of the fluid reservoir 240 again on the inside of itself.
- the distal end 222 of the catheter 220 resting at a position just right of centre across the width of the fluid collection bag 210 and between the fluid reservoir 240 and the catheter (tube) 220.
- the catheter 220 is positioned only within the third section of the fluid collection bag 210 and is prevented from moving out of this section by the fold line 242 (when the fluid collection bag is folded).
- the catheter may of course coil in the other direction as required.
- the distal end 222 of the catheter 220 does not comprise a funnel and instead comprises a cuff 223.
- the cuff 223 is configured to prevent movement of the distal end 222 of the catheter 220 through the aperture 254 of the neck 250.
- the cuff 223 comprises a protrusion extending parallel to the diameter of the catheter 220 and configured to contact the distal end 251 of the neck 250 preventing the catheter 220 from being completely withdrawn from the fluid collection bag 220.
- the packaged catheter assembly 200 of the second embodiment is used in a similar manner to the first embodiment.
- the neck 250, fluid reservoir 240 and catheter 220 are arranged below the drain 260 when the fluid collection bag 210 is opened.
- the fluid collection bag 210 must then be rotated through 180 degrees so that the neck 250 is positioned above the rest of the fluid collection bag 210 and the upper edge 215 and base 212 are at the corresponding top and bottom of the fluid collection bag 210.
- all three sections of the fluid collection bag 210 of the second embodiment needs to be unfolded.
- Drainage of the fluid collection bag 220 is achieved in this embodiment by unfolding the drain into the open extended configuration, for example by pulling the folded stowed drain up/away from the closure 216 as indicated by the opening marker 267.
- the pursing strips 266 are used to assist opening of the drain 260 by pinching them together as described above.

Abstract
Un ensemble cathéter comprend un cathéter, une poche de collecte de fluide conçue pour recevoir un fluide provenant du cathéter et un passage s'étendant à partir de la poche de collecte de fluide. Le passage a des configurations étendue et rangée où, dans la configuration étendue, il s'étend au-delà d'un bord de la poche et permet au fluide de passer à l'intérieur/à l'extérieur de la poche, et dans la configuration rangée, il est plié ou enroulé pour empêcher l'écoulement de fluide à travers celui-ci. Le passage peut être disposé dans la configuration rangée. Le cathéter peut être retenu dans le passage. La poche de collecte de fluide peut comprendre deux sections ou plus. L'ensemble cathéter peut comprendre un réservoir de fluide. Le cathéter et le réservoir de fluide peuvent être disposés dans la même section de la poche. L'ensemble cathéter peut comprendre une fermeture conçue pour sceller le passage dans la configuration rangée. Le passage peut être un col ou un drain.
