Definitions
- This invention relates to syringe safety shields and in particular, but not exclusively, to such arrangements used in a disposable syringe arrangement for use in an autoinjector.
- a disposable syringe arrangement for use in an autoinjector.
- safety requirements demand that, after use, the disposable components are in a safe state to reduce the risk of needle stick injuries.
- a syringe safety shield assembly that can be used either manually where an autoinjector is not available, or in an autoinjector, in each case providing needle stick protection post injection.
- autoinjectors that provide a lock out needle shield for shielding the needle on completion of an injection
- such devices either are designed as single use disposable autoinjectors, with the consequential environmental impact, or multiple use injectors in which the spent syringe is removed, allowing reuse of the autoinjector, but without shielding of the needle.
- this invention provides an autoinjector system comprising an autoinjector device having a housing for receiving a disposable syringe assembly comprising a syringe having a syringe barrel, a needle at the forward end and a plunger, in combination with a safety shield arrangement, comprising: a syringe housing receiving said syringe barrel and restrained against longitudinal movement with respect thereto, a shield portion mounted for generally telescopic movement relative to said syringe housing between a retracted position and an extended position in which in use it shields said syringe needle, and a lock out arrangement effective as said shield moves towards its extended position to prevent retraction therefrom, the autoinjector including a drive mechanism for advancing said syringe to an injection position, for driving said plunger to expel a dose and for moving said shield portion to its locked out extended position, whereby, on completion of an injection operation, said disposable syringe assembly may be removed from said autoinjector
- a safety shield arrangement for use with a syringe having a syringe barrel, a needle at the forward end of the barrel and a plunger, said arrangement comprising: a syringe housing for being coupled to said syringe barrel in use and restrained against longitudinal movement with respect thereto, a shield portion mounted for a generally telescopic movement relative to said syringe housing between a retracted position and an extended shielding position in which in use it shields said syringe needle, and a lock out arrangement effective as said shield moves towards its extended position to prevent retraction therefrom.
- said syringe housing has engagement means resiliently to retain the syringe therein, such as for example surfaces providing a snap-fit for ease of assembly.
- the lock out arrangement may comprise a resiliently deformable latch on one of said syringe housing and said shield portion, with the latch being snap- engageable with a latch surface on the other of said syringe housing and said shield portion.
- the extent of forward extension movement of said shield relative to said syringe housing may be limited by cooperating stop surfaces.
- a latch may be provided for releasably retaining the shield portion in a retracted position prior to forward extension thereof.
- an autoinjector adapted to receive in use a removable syringe assembly, including a syringe having a barrel, a needle at the forward end of the barrel and a plunger for expelling a dose through said needle, and a shield for being moved forwardly to shield the needle after injection, said device comprising: a housing, a drive mechanism including a drive member releasable for forward movement in use to drive said syringe plunger forwardly, a syringe carriage for imparting forward movement of the syringe barrel relative to said housing, a shield carriage for imparting forward movement of the shield relative to said syringe carriage, and a control element associated with said drive member arranged to prevent forward movement of said shield
- the autoinjector preferably includes a syringe carriage bias means urging the syringe carriage forward relative to the housing, with there also being shield carriage bias means for urging said shield carriage forwardly relative to said syringe carriage.
- said control element cooperates with said drive member and at least one of said syringe carriage and said shield carriage when the drive member is in a primed position to retain both the syringe carriage and the shield carriage in retracted positions but when released allows movement of both relative to the drive member and to each other, such that each is independently movable.

- FIGS 18(a) and (b) are detailed views on the trigger assembly of the autoinjector.
- Figures 19 (a) to (f) are views showing the cycle of operation of the autoinjector of Figures 9 to 18.
- a safety syringe shield arrangement will firstly be described. This arrangement is designed to be fitted in the autoinjector that is later described with reference to Figures 8 to 19 but it also may be used to provide shielding for manual use syringes.
- FIG 1 there is shown a syringe 10 having a plunger 12, a barrel 14 (see Figure 2) with an outturned flange 16 with the syringe needle being covered prior to injection by a cap 18.
- the syringe is fitted inside a shroud assembly comprising a syringe carrier 22 of open trough form having a fitting 24 at its rear end for engaging the flange 16 of the syringe barrel and having outwardly directed barbs 26 connected on thin flexible strips defined by slits 28 in the carrier.
- the shield 30 has a lower cylindrical portion of diameter to fit telescopically over the carrier 22 and an upper cylindrical portion of slightly lesser diameter designed telescopically to slide over the barrel of the syringe 14.
- the shield has two slots 32 which, when the syringe carrier 22 is slid inside the shield 30 cooperate with the barbs 26 to limit extension movement of the shield 30.
- the slits 28 on the syringe carrier allow the barbs 26 to deflect inwardly to allow assembly but, once the syringe 10 is inserted inward deflection of the barbs is prevented by the syringe barrel 14.
- Figures 4(a), (b) and (c) are detailed views on the end showing how the flange of the syringe can be snapped into engagement with the fitting 24. Also visible in Figure 4(c) is a retention latch 34 which lightly clips the shield 30 in a retracted position relative to the syringe carrier 22. This can be seen in more detail in Figures 5 and 6. It will be seen that the retention latch 34 is at the end of a flexible finger 36 which allows the latch to disengage when sufficient pull is applied to the shield 30. The retention latch engages in a recess 36 forming part of the end fitting of the syringe carrier 22.
- the radially inner surface of the finger 36 is provided with a lock out latch 38 that runs in a slot 40 on the syringe carrier. At its forward end, the slot 40 terminates in a ramp surface, forwardly of which is a lock out recess 43. Forward of the flexible finger 36, and on a relatively inflexible portion of the shield 30, is a drive lug 42 for use in the autoinjector to drive the shield forward on completion of an injection.
- the above syringe safety shield arrangement therefore allows the syringe to be snap-fitted into the syringe carrier 22 and, after injection, the shield 30 to be pulled forwardly until locked out by engagement of the lock out latch 38 in the lock out recess 43.
- this includes an outer casing 52 closed at the rear end but providing an open access forward end into which a module comprising a syringe fitted into the safety shield described above can be fitted for injection.
- the autoinjector is primed by sliding a cover portion 54 rearwardly to cock a plunger 56, the arrangement is then fired by pushing a button 58 on the rear end of the device sub-flush.
- a syringe carriage 60 which is biased forwardly by twin syringe carriage springs 62.
- the plunger 56 is urged forward by a constant force spring 64, the front end of which is anchored on the inside of the housing 52.
- a slotted reset arm 66 is secured to the plunger and moves longitudinally with it, to control movement of the syringe and various components to be described below.
- a shield carriage 68 is slideably disposed on the underside of the syringe carriage and has a drive interface 70 designed to receive in use the drive lug 42 of the shield 30 in a releasable snap- fit.
- the shield carriage has twin side ribs 72 which cooperate with a T-shaped formation 74 on the forward end of the reset arm 66.
- the shield carriage 68 is biased forwardly by twin shield carriage springs 76.
- the inner surface of the syringe carriage 60 has an arcuate recess 78 designed to receive the end fitting 24 on the syringe carrier 22. Extending rearwardly from the arcuate recess 78 are twin flexible arms 80 which engage within the housing.
- On the underside of the syringe carriage are provided laterally extending anchorage lugs 82 on which the forward ends of the shield carriage springs 76 are anchored.
- lateral anchorage lugs 82 To the rear of the lateral anchorage lugs 82 are two downwardly extending anchorage lugs 84 on which the rear ends of the syringe carriage springs are anchored.
- a peg 86 On the underside of the formation defining the annular recess 78 is a peg 86 which slides in a slot 88 in the slotted reset arm 66.
- the reset arm 66 provides a sequencing function, restraining the syringe carriage 60 and the shield carriage 68 against forward movement until the plunger 56 has been released to move forwardly under the influence of the constant force spring 64.
- the plunger in its rearward position and engagement of the peg 86 on the syringe carriage in the forward end of the slot 62 restrains movement of the syringe carriage under the influence of the carriage springs 62.
- engagement of the T-formation 74 with the rib 72 on the shield carriage means that the shield carriage is prevented from forward movement with respect to the syringe carriage.
- the reset arm in this position therefore retains both the syringe carriage and the shield carriage in fully retracted positions.
- FIGS 18 (a) to (c) show the trigger arrangement in this embodiment.
- the drive plunger 56 has two flexible barbs 90 that can slide past and be captured by complementary barbs 92 on the inner wall of the housing, to retain the plunger in an energised position when pulled back against the spring bias of the constant force spring 64.
- the firing button 58 is connected to an inner sleeve 94 which, when the firing button 58 is pressed against the bias of a leaf spring 96 squeezes the barbs 90 inwardly so they disengage from the barbs 92 on the housing, thus allowing the plunger to move forward under the influence of the constant force spring 64.
- FIG. 19(a) a syringe with a safety shield arrangement as described above is fitted into an autoinjector which has been previously primed by sliding back the cover 54.
- the syringe is located by inserting it into the syringe carriage with the fitting 24 being received in the recess 78 and the drive lug 42 on the shield being received in the drive interface 70.
- the device is offered up to the injection site ( Figure 19(b)) and the trigger depressed.
- the plunger 56 shoots forward allowing the syringe carriage and the shield carriage to move the syringe and shield assembly forward.
- the syringe carriage On reaching its forwardmost position, the syringe carriage is arrested and the plunger 56 then expels a dose from the syringe (Figure 19(c)).
- the needle shield is moved forwardly by the shield carriage moving forwardly relative to the syringe carriage ( Figure 19(d)) until the needle shield is fully extended and locked out by the lock out latch 38 latching into the lock out recess 43.
- the syringe with the safety shield extended and locked out may then be removed ( Figure 19(d)) and disposed of safely.
- the autoinjector may then be re-primed by sliding the cover 54 rearwardly ( Figure 19(e)).
