The present invention relates to a syringe-coupled safety assembly and a safety syringe including the same. According to one aspect of the present invention, provided is the syringe-coupled safety assembly comprising: a cover having a space part for allowing a syringe to enter therein, and a first through-hole through which a syringe needle passes; and a fixing unit having a second through-hole into which a syringe hub, in which the needle is mounted, is inserted, disposed inside the cover so as to be capable of proceeding in the direction becoming closer to the first through-hole and of retracting in the direction becoming farther from the first through-hole, fixed to the cover in a proceeded state, and provided so as to allow the syringe inserted into the second through-hole to retract when the fixed state thereof of the cover is released from the proceeded state.

Embodiments provided herein include a resettable injection training device having a body, a plunger slidable relative thereto, an injection simulation member and retractable and extendable shield, wherein the shield releasably locks in a retracted position prior to use. After use of the training device, the shield extends over the injection simulation member to prevent contact with the injection simulation member. Resetting of the slidable shield occurs by applying a force onto a distal end of the shield to retract the shield until a shield locking surface interacts with a locking surface on the body to maintain the shield in a retracted position. Release of the shield from a retracted position to an extended position may occur by moving the plunger toward a distal end of the body until a contact region at a proximal end of the plunger releases the shield locking surface from the body locking surface to release the shield.

The invention relates to a syringe with a retractable needle comprising a barrel (2) having a nozzle (19) integrated in a male Luer adapter element (26); a piston (3) slidably arranged in the barrel (2) and coupled to a sealing element (16), said sealing element (16) having a central channel (20); a needle assembly comprising a needle (4), a needle holder (6) and a female Luer adapter element (7); a spring assembly arranged in the piston (3) comprising a spring sleeve (12), a spring (13) mounted on the spring sleeve (12), a spring tensioning element (14) located on the spring sleeve (12) and held in position by the piston wall, and a plunger (15) mounted within the spring sleeve; and a piston cap (10); said piston (3) being coupled to the sealing element (16) by means of the spring tensioning element (14); said spring sleeve (12) being held in position within the piston (3) by a ring element (18) protruding from the inner wall of the piston (3) and supporting the proximal end of the spring sleeve (12), the spring sleeve extending into the channel (20) of the sealing element (16) to the distal end thereof; said spring sleeve (12) comprising at its distal end a circular protrusion (21) on the inside designed to engage a circular recess (22) at the proximal end of the needle holder (6); wherein the piston (3) comprises a holding ring (11) on its inner surface designed to engage with an outer flange (17) of the spring sleeve (12) after actuation of the spring (13).

A needle module for a drive-controlled handheld unit for repeatedly piercing human or animal skin, comprising a housing; a needle holder, which can be moved back and forth in the housing in a longitudinal direction of the housing; a piercing device on the needle holder, which can be moved, on account of the movement of the needle holder, between a proximal and a distal position, in which a piercing tip of the piercing device is arranged outside the housing; a coupling component, which is coupled to the needle holder in such a way that a driving movement provided with a repetition frequency by a drive device that can be coupled to the coupling component can be introduced onto the needle holder; and a damping component, which is arranged between the needle holder and the coupling component and is configured to damp a transfer of force therebetween.

In an embodiment, a resettable injection training device and a method embodiment for resetting the device is provided herein. The device may include a housing having a proximal end and a distal end, the housing defining a cavity there within. A plunger may be slidable relative to the housing between the proximal end and the distal end. A releasably locking shield having a proximal end and a distal end, and being slidably engaged with the housing is also provided. The shield may be slidable between a retracted, pre-use position an extended, locked, post-use position. The device may further include a flat biasing member for locking the shield in the extended position, and a compressing component slidable relative to the housing, wherein pressure on the flat biasing member from the compressing component deforms the flat biasing member, and unlocks the shield, and wherein a release of pressure by the compressing component on the flat biasing member locks the shield in an extended, post-use position.

A container for delivering a medicament to a target location includes a housing having a proximal end and a distal end, the housing including a cap locking tab at the distal end, and a vial containing the medicament. The container includes a plunger slidable within the vial from a proximal end to a distal end of the vial to dispel the medicament, an injection member associated with the distal end of the vial, such that the medicament dispelled from the vial passes through the injection member to the target location, and a slidable interaction member associated with the distal end of the vial configured to slide with the vial. An interaction between the slidable interaction member and the cap locking tab causes the cap locking tab to bias outward, and placement of a safety cap on the container after use locks the safety cap onto the container via an interaction with the cap locking tab. The container may further include a resistance feature to control movement of a plunger rod relative to the vial.

A safety needle is disclosed having a puncture needle with a needle lumen and a ground tip; a holding device that, during use, bears on the skin of a patient and holds the puncture needle; and a safety mechanism with a protection element that has a first, opened state and a second, closed state. When the holding device is taken away from the skin and/or when the holding device is moved with respect to the defined position, the safety mechanism automatically moves the protection element from a first position, in which the tip of the needle is exposed, to a second position, in which the tip of the needle is covered as the protection element at the same time transfers automatically from the first, opened state to the second, closed state.

A safety housing based implant/medicament injecting system. The system includes a needle assembly prefilled with an implant/medicament for injection and an injecting needle/cannula, a housing for accommodating the needle assembly under usual bias inside said housing, a plunger means having a plunger rod configured for stage-wise forward motion including an initial-injecting plunger forward motion with the needle assembly within the housing to first engage the needle assembly with the housing and a subsequent continuing-injecting plunger forward motion independent of the needle assembly for injecting the implant/medicament. The needle assembly configured to return post-injecting to be secured inside said housing blocking any subsequent use thereof.

A fluid extraction device is provided for extracting fluid from a syringe assembly including a syringe port and a sleeve. The device includes a body with first and second ends, the first end defining a fluid entry port, and the second end defining a fluid exit port. A channel through the body connects the fluid entry and fluid exit ports. At least one push member extends radially from the body and is configured to contact the sleeve of the syringe assembly in use such to push it from a first position in which the sleeve closes the syringe port to a second position in which the sleeve exposes the syringe port.
