Abstract
The present invention relates to an autoinjector device (10) for use in combination with a syringe (30), said syringe comprising a movable plunger; a needle; and a tubular needle shield (34). The claimed autoinjector device (10) comprises: an elongated housing having a proximal (11) and a distal end (12); a drive mechanism; a syringe holder (40) in order to support the fragile syringe and to prevent damage to the syringe. The invention furthermore relates to a method for assembly of the autoinjector device according to the invention.
Description
- The present invention relates to an auto injection device for use in combination with a syringe, and a method for assembling said syringe in the autoinjector device.
- Different types of autoinjectors are frequently used in order to facilitate administration of drugs to patients. When the proximal end of the autoinjector is correctly positioned against the intended area of the skin of the patient, an activation means on the autoinjector is pressed in order to activate the autoinjector. When activated, a needle rapidly punctuates the skin and the drug is delivered via the needle automatically.
- There are two different categories of the autoinjectors on the market today. The first one uses custom designed medicament chambers, examples of these are described in WO2003/099358 and WO01/93926, while the second category uses standard pre-filled syringes. There are several advantages directed to the use of standard pre-filled syringes, for example the syringes have already been tested and approved in accordance with present regulations, which saves time and reduces the overall costs for the autoinjector. The present invention is directed to disposable autoinjectors used in combination with standard pre-filled syringes.
- Since the autoinjectors are often used for self-administration of a drug to, the punctuation of the patients skin and the delivery of the drug via the needle are preferably performed rapidly which requires that a significant force is applied to the syringe by the drive mechanism. However, syringes are fragile and when the force of the drive mechanism is applied, there is a significant risk that the fragile syringe breaks.
- In WO2007/083115 an autoinjector comprising a syringe support device intended to be arranged around the syringe and support the syringe at its front is disclosed. The support device reduces the risk of damage to the syringe but there is till a significant risk that the fragile syringe is damaged when a large force from the drive mechanism is applied upon activation of the autoinjector.
- There is consequently still a need for an improved autoinjector device that further reduces the risk of damage to the syringe.
- The present invention, defined in the appended claims, provides an autoinjector device that fulfils the needs defined above.
- The autoinjector device of the present invention is elongated along a longitudinal axis A and has a proximal end and an opposing distal end and comprises
-
- a syringe having a substantially circular cross section having an outer diameter, said syringe having a proximal end comprising a neck and a distal end provided with a from the outer periphery of the container radially extending flange; said syringe further comprising a movable plunger, a needle and a tubular needle shield having a outer diameter which is larger than the outer diameter of the syringe,
- an elongated autoinjector housing comprising a space for said syringe;
- a driving mechanism arranged in the distal end of the housing in order to, when the autoinjector is activated, apply a force on the movable plunger;
- a syringe holder having a syringe holder wall with a substantially tubular shape, said holder wall having:
- an open distal end provided with a distal supporting collar arranged around the outer periphery of said syringe holder wall to support said syringe by the radially extending flange,
- an open proximal end provided with a proximal supporting collar arranged around the inner periphery of said syringe holder wall to support said syringe neck, and
- a slot extending from said open proximal end in the distal direction resulting in a C-shaped cross sectional shape of the syringe holder wall in the proximal end.
- According to one aspect of the invention, the holder wall has a longitudinal length between the proximal supporting collar and the a distal supporting collar corresponding to the length of the syringe such that the a distal supporting collar of said syringe holder wall supports said radially extending flange of said syringe and said proximal supporting collar supports said neck of said syringe simultaneously when a force is applied on the movable plunger.
- According to a further aspect of the invention, the proximal supporting collar has a inner diameter which is lesser than the outer diameter of the syringe and
- According to another aspect of the invention, the proximal supporting collar has a inner diameter which is lesser than the outer diameter of the tubular needle covering shield.
- According to a further aspect of the invention the proximal supporting collar is capable of flexing radially outward for allowing the the tubular needle shield to pass through when the syringe is longitudinally mounted in relation to the longitudinal axis (A) within the syringe holder.
- The claimed invention fulfils the needs defined above since the syringe holder according to the invention provides support for the syringe along the entire length of the syringe. Furthermore the distal end of the syringe holder, due to the corresponding length of the syringe holder, will be in contact with the radially extending flange at the distal end of the syringe and support the flange when the force from the drive mechanism is applied. Since the syringe is supported both at the proximal end by the collar in contact with the neck and at the distal end by the flat surface in contact with the flange of the syringe, the risk that the syringe is damaged when a drive force is applied by the drive mechanism is reduced considerably.
- A further advantage with the claimed injector device is that the C-shaped proximal end of the syringe holder facilitates the fitting of the syringe in the holder since the C-shaped cross section makes it possible for the proximal end of the syringe holder to flex and thereby allow the tubular needle shield, even though it has a diameter exceeding the inner diameter of the collar, to be moved past the collar. Once the syringe is fitted in the syringe holder the C-shaped collar will provide the desired support around almost the entire syringe neck which is favourable since the load on the syringe neck will be distributed over a larger area and the risk of damage to the syringe is reduced considerably.
- In one embodiment of the invention, the autoinjector device comprises guiding means to control the movement of the syringe holder within the autoinjector housing when the syringe holder is longitudinally mounted in relation to the longitudinal axis (A) within the autoinjector housing. This is a favourable embodiment of the autoinjector device since the guiding means will assist during the preparation of the autoinjector device. The syringe is first fitted in the syringe holder by introduction of the proximal end of the syringe into the syringe holder via the distal end of the syringe holder and then moved in the proximal direction of the autoinjector device to the intended position within the proximal housing section during assistance by the guiding means that facilitates the mounting of the syringe and the syringe holder in the housing.
- In one embodiment of the invention, the guiding means comprises protrusions arranged along the outer periphery of the syringe holder wall and corresponding grooves arranged along the inner periphery of the autoinjector housing. This embodiment of the guiding means provides satisfying guiding during the preparation of the autoinjector device.
- One embodiment of the invention comprises corresponding openings or windows in the autoinjector housing and the syringe holder which make it possible to easily verify that the syringe is correctly fitted in relation to the syringe holder and the antoinjector housing.
- In one embodiment of the invention, the syringe holder comprises locking means that secures the syringe holder in relation to the autoinjector housing when the syringe holder is longitudinally mounted in relation to the longitudinal axis (A) within the autoinjector housing.
- In one embodiment of the invention, the outer periphery of the proximal end of the syringe holder is radially supported by a contact surface on the inside surface of the autoinjector housing when the syringe holder is in a proximal position within the autoinjector housing. This embodiment is favourable since the contact surface of the autoinjector housing will prevent the proximal end of the syringe holder wall from flexing radially outwards, which ensures that the syringe remains in the intended position in the syringe holder when the drive force is applied by the drive mechanism.
- The different embodiments described above could of course be combined and modified in different ways without departing from the scope of the invention that is defined by the claims. Further details of the invention will be described in the detailed description.

FIGS. 3 a to 3 c , selected components of anautoinjector device 10 according to the invention are illustrated. Theautoinjector device 10, elongated along a longitudinal axis A, is intended for self-administration of drugs and has aproximal end 11 and an opposingdistal end 12. - The autoinjector device comprises an autoinjector housing divided into a
proximal housing section 13 anddistal housing section 14 in order to make the space defined inside the housing accessible for assembly of the different components of the autoinjector. - The autoinjector housing has the shape of a tube. The autoinjector housing is intended to house a
pre-filled syringe 30 within asyringe holder 40. A drive mechanism (not shown) is also arranged within the housing. The drive mechanism is arranged to apply a proximally directed drive force to a movable plunger in the syringe in order to expel the drug through a needle (not shown). - The drive mechanism is not illustrated in detail in the drawings but different types of drive mechanisms are available. The drive mechanism may comprise a pre-tensioned spring which upon activation applies a pre-determined pressure via plunger rod (not shown) to the movable plunger arranged in a distal end of the syringe.
- The autoinjector is intended for use in combination with a standard pre-filled
syringe 30. Thesyringe 30, assembled in thesyringe holder 40 illustrated in perspective inFIG. 2 , has a substantially circular cross section having an outer diameter. The syringe is normally made of glass in order to ensure a reliable and hygenic storing of the drug in thesyringe 30. At a proximal end of thesyringe 30, the outer diameter is reduced and shaped like aneck 32 at which a needle (not shown) andneedle shield 34 are attached before delivery of the syringe. In order to ensure that the needle remains sterilized before use, the needle is protected by theneedle shield 34 having a substantially circular cross section and having an outer diameter which is larger than the outer diameter of the elongated syringe. Thetubular needle shield 34 may be a so-called Rigid Needle Shield (RNS). Further, thetubular needle shield 34 encloses the needle and is removably fastened to thesyringe 30 at theneck 32. The distal end of the tube-shapedsyringe 30 is arranged with aradially extending flange 35. Thesyringe 30 furthermore comprises a movable plunger arranged in the distal end of thesyringe 30 to seal thesyringe 30 and ensure that the pre-filled drug of the syringe remains in thesyringe 30. The movable plunger is preferably made of a rubber material in order to achieve a seal between the inner periphery of thesyringe 30 and the plunger. - The
syringe 30 is secured in the autoinjector housing by asyringe holder 40 that is described in more detail below. Thesyringe holder 40 is arranged in the proximal housing section in order to support and maintain thesyringe 30 in a pre-determined position in relation to the syringe holder and the autoinjector housing. During assembly of the autoinjector, thesyringe 30 is first inserted in thesyringe holder 40, which is then moved in the proximal direction of theautoinjector device 10 to a forward position where thesyringe holder 40 is secured in the proximal housing section. The movement of the syringe holder in the proximal housing section is facilitated by guidingmeans 41 consisting of corresponding longitudinal protrutions 42 along the outer periphery of thesyringe holder 40 and longitudinal recesses along the inner periphery of the proximal housing section. Furthermore corresponding snap-fitting fastening means 43 are arranged on thesyringe holder 40 and the proximal housing section in order to permanently secure the syringe holder in the desired proximal position within the proximal housing section. - The
syringe holder 40 provides a reliable and effective support for thefragile syringe 30 and reduces the risk of damage to thesyringe 30. One embodiment of thesyringe holder 40 is illustrated inFIG. 2 in a perspective view, where it is separated from the other components of the autoinjector device. Thesyringe holder 40 has a tubularly shapedholder wall 44 with aproximal end 45 and adistal end 46. Theproximal end 45 of the syringe holder is open but provided with a proximal supportingcollar 47 arranged around the inner periphery of said syringe holder wall in order to support saidsyringe neck 32 in the proximal longitudinal direction. Further, the proximal supportingcollar 47 has a inner diameter which is lesser than the outer diameter of the elongated syringe and thus also lesser than the outer diameter of the tubular needle shield. Aslot 48 extends from said open proximal end in the distal direction resulting in a C-shaped cross sectional shape of the syringe holder wall in the proximal end. The C-shaped holder wall in theproximal end 45 is able to flex radially outward which is essential in order to fit thesyringe 30 in thesyringe holder 40 since thetubular needle shield 34 has an outer diameter exceeding the inner diameter of the opening in the proximal supportingcollar 47. This means that thesyringe 30 may be fitted in thesyringe holder 40 from thedistal end 46 of the syringe holder. Thesyringe 30 is then moved in the proximal direction within thesyringe holder 40. When the tubularneedle covering shield 34 reaches the proximal supportingcollar 47, the C-shaped holder wall will flex radially outward and thereby make it possible to move thesyringe 30 further until theneck 32 of thesyringe 30 is in contact with thecollar 47, i.e the desired position of thesyringe 30 within thesyringe holder 40. In this position theneedle shield 34 has completely passed the supportingcollar 47, allowing the C-shaped holder wall to flex back, radially inward, behind the needle shield, such that the collar supports the syringe at theneck 32. - The
syringe holder 40 furthermore comprises a distal supportingcollar 49 arranged around the outer periphery of saidsyringe holder wall 44 and has a longitudinal length between the proximal supportingcollar 47 and a distal supportingcollar 49 that corresponds to the length of thesyringe 30 so that the distal supportingcollar 49 of said syringe holder wall, when thesyringe 30 is fitted in the desired position within thesyringe holder 40, is in contact with the proximal side of theradially extending flange 35 of thesyringe 30 and provides further support for thefragile syringe 30 within thesyringe holder 40 at the same time as the proximal supportingcollar 47 supports theneck 32 of saidsyringe 30. Thereby the risk of damage to thesyringe 30 is reduced significantly. Thesyringe holder 40 furthermore comprises guiding means that facilitates its movement in the longitudinal direction of the autoinjector device and locking means for securing the syringe holder in the proximal housing section before assembly of the syringe in thesyringe holder 40. - The proximal housing section is furthermore provided with a
window 15, or opening, corresponding to theslot 48 in thesyringe holder 40 when thesyringe holder 40 is fitted in the intended position in the proximal housing section in order to make thesyringe 30, and the drug in the syringe, visible from the outside of the autoinjector housing and possible for the patient to verify that the autoinjector device is correctly assembled and ready for use. - Three different assembly steps of the autoinjector device are schematically illustrated in
FIGS. 3 a-3 c . InFIG. 3 a , the proximal housing section and thesyringe holder 40 are illustrated without thesyringe 30 fitted in thesyringe holder 40. Thesyringe holder 40 is movably arranged in the proximal housing section between a distal position and a proximal position. Prior to fitting the syringe in the syringe holder the syringe holder is arranged in the distal position ready for assembly. - The assembly of the
autoinjector device 10 is initiated by fitting thesyringe 30 in thesyringe holder 40 by inserting the proximal end of the syringe in the distal end of thesyringe holder 40 and pushing the syringe in the proximal direction until theneck 32 of thesyringe 30 is in contact with thecollar 47 in the proximal end of thesyringe holder 40, illustrated inFIG. 3 b . Thesyringe 30 and thesyringe holder 40 are then moved simultaneously in the proximal direction to the proximal position in the proximal housing section. In the proximal position, the outer periphery of the proximal end of thesyringe holder 40 will be surrounded by support surfaces 16 on the inside surface of the proximal housing section. The cross sectional shape of the support surfaces correspond to the outer periphery of the syringe holder in order to provided a rigid support and prevent the C-shaped wall of the proximal end from flexing radially outwards in order to secure thesyringe 30 in thesyringe holder 40 and theautoinjector device 10, illustrated inFIG. 3 c . Finally, the autoinjector housing is closed around thesyringe 30 by fitting the distal housing section to the proximal housing section. - The assembly method of the present invention accordingly comprises the steps:
-
- a). Inserting the proximal end of the
syringe 30 in the distal end of thesyringe holder 40; - b). Moving the
syringe 30 towards the proximal end of the syringe holder until theneck 32 of thesyringe 30 is in contact with the proximal supportingcollar 47 and theradially extending flange 35 of thesyringe 30 in contact with the distal supportingcollar 49 of thesyringe holder 40; - c). Moving the
syringe holder 40 and thesyringe 30 simultaneously towards the proximal end of theautoinjector device 10.
- a). Inserting the proximal end of the
- The different embodiments described above could be combined in different ways and modified further without departing from the scope of the invention that is defined by the claims.
