摘要： Hypodermic syringe or medical sampler has a hollow needle (115) that is automatically retractable after use. A one-piece body (101) moulding has a main chamber for a plunger (105) or sampler container or drug cartridge, a forward chamber (111) to house a spring (133) to bias a needle holder (117), and internal latching formations (141) to retain the needle holder (117) with the spring (133) compressed in the forward chamber until automatic retraction when the latching formations (141) are released by end of plunger movement. Direct plunger-to-body sealing involves an over-size plunger head (105 H) forcing head and wall deformation. Both ends of the spring (133) have seals (119, 160) for the forward chamber (111). The needle, its holder, spring and seals can be installed using a sliding guide. Pressure testing can be combined with needle lubrication, and retraction prevention with sterilising tell-tale. The plunger (105) has top and grip formations (105 F) for the needle holder (117), and the needle can be double ended for taking samples or emptying drug cartridges.

摘要： To eliminate needle-stick risk by encapsulating the needle of a syringe immediately after discharge of syringe contents (43), the entire syringe, such as a pre-filled miniature glass syringe (40), is housed in a device comprising a hollow body (10), a spring (20) and a plunger (30). The barrel (41) of the syringe (40) is held in the body interior against the force of the spring (20) by latching formations (IS) internal to the body (10). The plunger (30) itself is hollow so as to provide a chamber (36) to receive the syringe piston means (45, 46) and at least part of the barrel (41) upon retraction of the syringe. The plunger (30) has deflectable engagement elements (33) at its forward end so that as it is pushed in to the body (10), it reliably displaces the syringe piston/rod (45, 46) to discharge the syringe contents (43) via a hollow needle (42), the elements (33) ultimately being deflected outwards as the contents are fully discharged so as not to impede syringe retraction into the hollow plunger (30). The plunger (30) also has latch opening projections (34) at its forward end which, as the plunger (30) is pushed home, serve to disengage, e.g. by deflection, the latch formations (18). The syringe barrel (41), together with the needle (42) and piston means (45, 46) are then immediately retracted into the device by force of the spring (20).

摘要： A fluid filled cartridge (110) having a fixed needle (107) and a piston assembly (111, 131, 133) for expression of its contents (112) is mounted inside an applicator (101). In order to extend the needle (107) from the body (101) prior to cartridge contents expression and without premature leakage of fluid therefrom, an actuator (120), which may be operated by spring (125) or manually, is mounted in the body to drive the cartridge forwards. This is accomplished by co-operating driving (126) and driven (110E) parts of the actuator and the cartridge (or any carrier it may have) which are decoupled by release formations, e.g. triggering extensions (128), in the applicator body (101) after the cartridge (110) has been moved sufficiently to extend the needle (107). Specifically, the driving part (126E) may be deflected outwardly by the triggering extension (128). The applicator (100) may also include provision, including, for example, forwardly mounted spring (113), for automatic needle retraction after cartridge contents expression. This may be accomplished by further driving extensions (132) on the actuator (120) being released, e.g. by the action of trigger rod (133), from their drive coupling with parts (131E) of the piston rod, e.g. by outward deflection of the latter, after the piston (111) has been depressed a sufficient distance to express the contents (112). A separate inventive feature is the deformability of the piston (111) so that force transmission to the trigger means (133) to initiate needle retraction only occurs upon full content expression when the piston has “bottomed out” within the cartridge (110).

摘要： Hollow-needle device (100) comprises a hollow plunger (105), a body part affording a cylindrical chamber (101) within which the plunger (105) is sealingly slidable, a needle-carrying hub (120) for automatic retraction into the plunger (105), and a closure (130) for the plunger (105). The closure (130) comprises a member (131) normally in sealing relation with end-adjacent internal provision (133) of the hollow plunger (105) but disengageable therefrom and bodily movable into the hollow plunger (105) by localised first engagement (135) of the member (131) at or near end of contents expression stroke of the plunger (105).

摘要： A syringe device for cartridged drugs has automatic needle retraction after cartridge contents expression. Drug cartridge (50, 125) is at least partially accommodated within a hollow piston actuator or carrier (30, 145, 245) and is released for further retraction under bias (22, 121) thereinto by way of a piston rod (40, 132, 232). Piston rod (40, 132, 232) serves to operate piston (52, 130) contained in the drug cartridge and has deflectable locking arms (42, 137, 237) that extend sideways into latching engagement with holding formation (38, 147, 247) of the piston actuator. Release of the arms by engagement with the open rear end of the cartridge (50, 125) permits retraction of needle and cartridge. Automatic needle insertion and cartridge contents discharge is also foreseen.

摘要： A needle retraction medical device including a hollow body (10) and a plunger (20). The hollow body (10) has a first end (11) provided with a needle mounting hub (13) and a plurality of releasable latches (15) holding the needle mounting hub (13) against spring (14) bias. The latches (15) are formed integrally with the hollow body (10) and project longitudinally inside the hollow body (10) from a proximal end at or adjacent the first end (11) of the hollow body (10) to a free end. A respective opening (35) is provided in the body (10) radially inwards of each of the latches (15). The plunger (20) has a forward end insertable into the body (10) from a second end thereof, a hollow interior and a closed rear end. The plunger front end is operable, upon insertion of the plunger (20) into the body (10), to deflect the latches (15) radially outwards and thereby release the needle mounting hub (13) from the latches (15) so that the hub (13) together with the needle mounted thereby retract under spring action into the hollow interior of the plunger (20). A respective opening (30) is also provided in the hollow body (10) radially outwards of at least some of the latches (15) so that each such latch (15) connects to the material of the body (10) only at each side of its proximal end.

摘要： First and second hollow needles (101, 102) extend from opposing sides of a common hub (107). Proximal ends (202, 204) of the respective needles (101, 102) are in communication with each other by a narrow passageway (103, 113) through the hub (107) which is formed in one piece and of transparent material. The hub (107) preferably includes a magnifying formation overlying the passageway portion (113) between the proximal ends of the needles (101, 102). As shown, the device (10) may be mounted in a front end of a tubular holder, such as a syringe body (30). In other versions the needles (101, 102) may be offset but parallel to one another (Fig. 2) or the principal ayes of the needles may intersect at an angle of between 1 ° and 45° (Fig. 4 and 5).

摘要： A fluid filled cartridge (110) having a fixed needle (107) and a piston assembly (111, 131, 133) for expression of its contents (112) is mounted inside an applicator (101). In order to extend the needle (107) from the body (101) prior to cartridge contents expression and without premature leakage of fluid therefrom, an actuator (120), which may be operated by spring (125) or manually, is mounted in the body to drive the cartridge forwards.

A separate inventive feature is the deformability of the piston (111) so that force transmission to the trigger means (133) to initiate needle retraction only occurs upon full content expression when the piston has “bottomed out” within the cartridge (110).
