An injector for delivering a medicament includes an outer sleeve, an inner sleeve, and a syringe. The inner sleeve is disposed partially within the outer sleeve. A plunger rod of the syringe is engaged with the outer sleeve in a fixed spatial relationship such that the plunger rod and the outer sleeve translate as a unit. The outer sleeve is configured for axial translation relative to the inner sleeve from a first configuration wherein the inner sleeve extends from the outer sleeve a first distance to a second configuration in which the inner sleeve extends from the outer sleeve a second distance that is less than the first distance. Further, in a third configuration the inner sleeve extends from the outer sleeve a third distance that is greater than the second distance and the inner sleeve is restricted from axially translating with respect to the outer sleeve.

The invention pertains to a kit for assembling a disposable applicator for inserting an implant, in particular a rod-like implant containing an active substance, under the skin of a human or animal, the kit comprising a first component, in turn comprising a main housing part providing a handle for grasping and maneuvering the applicator, a cannula, and a cannula holder mounted in the main housing part, the main housing part having an opening which allows introduction of an implant into the proximal end of the cannula or the cannula holder, and, a second component for closing said opening, in turn comprising a second housing part and a rod attached to or forming an integral whole with the second housing part and mountable inside the cannula or the cannula holder.

An injector for delivering a liquid medicament is provided. The injector comprises: a housing having an opening at a first end and a cartridge contained within the housing, wherein the cartridge comprises a first fitting mechanism which is directed outwards from the opening of the housing; a removable cap; and a needle assembly supported on the removable cap, wherein the needle assembly has a second fitting mechanism which is directed outwards from a distal end of the removable cap, the removable cap being further configured such that each of the distal end and the proximal end of the removable cap are engageable with the opening of the housing, wherein the first fitting mechanism is complementary with the second fitting mechanism such that the needle assembly is connectable to the cartridge by joining the first and second fitting mechanisms.

The present invention relates to drug delivery systems that cannot be reloaded or reused and further include a passive safety shield system. The drug delivery devices described herein include a drug container comprising at least one bellow, a needle, wherein the needle is in liquid communication with the drug container; a plunger extending between a proximal end and a distal end, wherein the plunger is in communication with the drug container and where upon axial movement of the plunger, the drug container is compressed.

A multi-use needle assembly (200) for an injection device (50), wherein the injection device (50) comprises: a housing (52) and a cartridge (54) for storing a liquid drug for multiple injections, the multi-use needle assembly comprises: a support structure (201), needle cannula (210), a movable shield assembly comprising a movable shield (220) and an actuation member (222) fixed to the shield (220), and a cleaning assembly (230) adapted to change configuration by deformation. The shield (220) is adapted to be in a locked distal position, an unlocked distal position and an unlocked proximal position, and the cleaning assembly (230) is adapted to be configured in (i) an open configuration, wherein a gap is provided between an outer surface of the cannula (210) and the cleaning assembly (230) to allow adjustment of the relative axial position between the cleaning assembly and the cannula, (ii) a closed configuration, wherein the cleaning assembly (230) is configured to provide contact with the outer surface of the cannula to enable cleaning of the cannula. The actuation member (222) is adapted to deform and thereby operate the cleaning assembly (230) between the open and the closed configuration, in response to turning the shield between the unlocked and the locked configuration. The needle assembly (200) is adapted to enable cleaning of the cannula (210), when the shield (220) is in the locked distal position, and to allow exposure of the cannula (210), when the shield (220) is in the unlocked distal position.

The present application discloses a safety injection device including a needle, a needle hub, an elastic member, a slider, a needle shield, a protective sleeve, and an outer cover. The needle hub, the elastic member, the slider, the needle shield and the protective sleeve are sleeved in sequence with the needle as a shaft. The slider is configured to rotate irreversibly after a single use. The safety injection device according to the present application has a simple and reasonable structure, and is safe, stretchable, and easy to use. In addition, it avoids fear of the needle tip during injection when use. After use, the injection device utilizes the eccentric principle to prevent from being fully depressed again, and the needle tip will not be exposed again, thereby more effectively avoiding the risk of cross infection caused by accidental contact with the needle tip after use.

A safety needle device is disclosed comprising a hub, needle cannula, housing, tether, retractable sleeve, locking member and spring element. The tether is slidably disposed in the housing, the tether having a slot with an enlarged first guide path and a narrowed second guide path extending distally from the enlarged first guide path. The retractable sleeve is configured to move between an initial position, retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula.

Contemplated herein is a medication mixing device which can include a housing having therein a first chamber containing a first medicament component and a second chamber provided containing a second medicament component provided with a sealing structure selectively isolating the first chamber from the second chamber. The sealing structure can include a first sealing component having a first sealing interface and a second sealing component having a second sealing interface wherein a first compression force can be applied to the first and second sealing components causes the sealing interfaces to form a seal. The first compression force can then be configured to allow the first sealing component and the second sealing component to maintain at least one degree of freedom with respect to one another.

A needle guard device mountable to a pre-filled syringe in its ready-to-fill state. The device includes a device shield interconnected to a lock collar with flexible member and biased to move relative to the lock collar. The lock collar interfaces with the syringe neck to attach the device to the syringe. As the device shield moves proximally, rotation arms of the lock collar interact with angled cutouts in the device shield, causing the device shield to rotate relative to the lock collar and disengaging one or more keys on the device shield from one or more keyways in the lock collar triggering the device shield to move from a first configuration in which the device shield is retractable to expose a syringe sharp to a second configuration in which the device shield is fixedly positioned to cover the syringe sharp.

The invention relates to an injection device for injecting a liquid drug. The injection device comprises a housing assembly supporting a non-removable cartridge having an interior chamber containing the liquid drug to be injected and a reusable needle cannula connected to the cartridge. A needle shield assembly provided with a cleaning chamber containing a volume of a cleaning agent for cleaning at least the distal tip of the needle cannula between subsequent injections is further provided. The needle shield assembly is axially movable in a proximal direction in relation to the housing assembly from a first position to a second position upon rotation of at least a part of the needle shield assembly, wherein the first position is a position in which the distal tip of the needle cannula is located inside the cleaning chamber thereby cleansing the distal tip of the needle cannula, and the second position is a position in which the distal tip of the needle cannula is located outside and distal to the cleaning chamber for equalizing the pressure in the cartridge.
