摘要： The disclosure relates to a safety system for a medical injection device including a barrel, a needle, and a stopper. Said safety system includes a body, the medical injection device being movable relative to the body between an initial distal position and a final safety position. The body includes at least one first locking member configured to releasably lock the medical injection device in the initial position, and a plunger rod configured to drive the stopper in distal direction. Said plunger rod being axially collapsible between an initial extended configuration and a final retracted configuration. The plunger rod and the locking member being configured so that when the stopper abuts at the distal end of the barrel, a safety activation force exerted onto the plunger rod in distal direction collapses the plunger rod, causing the body to move to the final safety position.

摘要： A needle guard assembly includes a needle cannula defining a lumen having a proximal end, a distal end with a sharpened tip, and a tubular body extending between the proximal end and the distal end. The needle guard assembly also includes a needle hub connected to the proximal end of the needle cannula configured to be mounted to a fluid delivery device to provide fluid communication between the fluid delivery device and the lumen of the needle cannula and a liquid-permeable cover member extending over at least the distal end of the needle cannula having a proximal end engaged to the needle hub and a closed distal end enclosing the distal tip of the needle cannula.

摘要： A medical syringe having a forwardly projecting needle that is selectively retractable following use and also having a specially configured plunger handle and thumb cap that cooperate to form a concave pressure application surface (“CPAS”). The concave pressure application surface at the rear of the plunger handle enables the subject medical syringe to achieve functional advantages, each with an associated therapeutic benefit, that are not achieved with use of the prior art devices.

摘要： Some embodiments are directed toward a safety needle assembly including a hub having a proximal end for connecting with a syringe extending in a proximal area of the hub; a needle longitudinally extending from a distal end of the hub in a distal area of the hub; and a sheath pivotally connected to the hub. The sheath can have two side walls connected by a back wall defining a receiving space therebetween for receiving the needle; wherein the sheath is adjustable between a starting position in which the sheath is substantially positioned in the distal area of the hub, between a use position in which the sheath is substantially positioned in the proximal area of the hub, and between a locked position in which the sheath is locked to secure the needle into the receiving space.

摘要： A system for mixing drug products and injecting includes a syringe body, proximal and distal stopper members disposed in the syringe body, a plunger member, and a needle hub assembly coupled to the distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber between there between and a distal drug chamber between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention feature, an energy-storage member, and an energy-storage member latching member all disposed in disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body. The needle is at least partially retractable into plunger interior upon manipulation of the plunger member relative to the syringe body.

摘要： A therapeutic agent delivery system includes a therapeutic agent delivery assembly carried by a housing. The therapeutic agent delivery assembly includes a chamber including a first passageway, a therapeutic agent carried in the first passageway, and a needle in communication with the first passageway. The therapeutic agent delivery assembly is translatable relative to the housing from a stowed configuration to a deployed configuration. In the deployed configuration the needle at least partially extends distally from the distal end portion of the housing. The therapeutic agent delivery assembly is translatable relative to the housing from the deployed configuration to a retracted configuration. In the retracted configuration the needle is disposed proximally relative to the distal end portion of the housing. A drive mechanism translates the therapeutic agent delivery assembly from the stowed configuration to the deployed configuration and from the deployed configuration to the retracted configuration.

摘要： A microneedle injection and infusion apparatus, and a method of using same. The apparatus can include a housing, a microneedle array holder for holding a microneedle array, and a shuttle that holds a cartridge (e.g., that contains an active agent). The microneedle array holder can be movable between a retracted position and an extended position. The shuttle can be movable between a first position in which the cartridge is not in fluid communication with a fluid path and a second position in which the cartridge is in fluid communication with the fluid path. The apparatus can further include an actuator movable between a first position and a second position. The method can include moving the actuator to its second position to allow the shuttle to move toward its second position, wherein movement of the shuttle toward its second position allows the microneedle array holder to move to its extended position.

摘要： A safety syringe structure includes a combined structure of a syringe barrel, a needle retreater, a needle, and a plunger. The needle retreater and the plunger are slidably received in the syringe barrel. The needle retreater is arranged adjacent to the front end of the syringe barrel. The needle is coupled to the needle retreater. The plunger has an end extended to form a sharp tip and is provided with a plug facing the needle retreater. The sharp tip extends outside the plug in a direction toward the needle retreater. The sharp tip is movable with the plunger toward the front end of the syringe barrel to pierce into and couple with the through hole of the needle retreater; and the sharp tip is movable with the plunger toward the rear end of the syringe barrel to drive, through the needle retreater, the needle into the channel.

摘要： A connector mountable to a syringe barrel has a proximal barrel-engaging portion, a distal luer fitment portion, and a fluid aperture therethrough. The barrel-engaging portion of the connector includes an axial ledge configured to abut the axial distal edge of a glass syringe barrel. The connector facilitates mounting a luer assembly to the barrel. The luer assembly may be a tip cap, a luer needle assembly, or a luer needle-less assembly, having a complementary luer fitment for connection to the luer fitment portion of the connector. The connector and syringe may further include an immobile, compressible needle seal. The needle seal is adjacent to or engageable with the barrel-engaging portion of the connector.

摘要： A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.
