A needle end and a safety syringe are provided, belonging to technical field of medical instruments. The safety syringe includes an injection end, a liquid storage device, and a base. The injection end includes a needle base, an injection needle, and a needle guard assembly. The injection needle is fixed to the needle base. The needle guard assembly is connected to the needle base. The needle guard assembly includes a protective casing and a spring, wherein a first terminal of the spring is connected to the needle base and a second terminal of the spring is connected to the protective casing. The liquid storage device includes a liquid storage container and a liquid storage sleeve. The liquid storage is sleeved on an outer surface the liquid storage container, wherein the liquid storage container is detachably connected to the injection end. The base is detachably connected to the liquid storage device.

The present invention relates to a medicament delivery device comprising a housing (10, 20, 24, 30), a biased medicament delivery member guard (64) arranged movable in relation to the housing from a proximally extended position to a retracted position, a power pack (87) comprising a plunger rod (88) and a force element (118) arranged to act on said plunger rod (88), which power pack (87) is actuated by a release clip (96) movable in relation to the housing and arranged to said plunger rod (88) for releasibly holding said plunger rod (88) with the force element (118) in a tensioned state; a rotator (82) rotatably arranged inside said housing, which rotator (82) is arranged with a guide element (80) and a medicament delivery member guard lock element (84, 86) on its outer surface, wherein said medicament delivery member guard (64) is arranged with release clip activation elements (112) operably arranged to act on said release clip (96) for releasing said plunger rod, and wherein said medicament delivery member guard (64) is further arranged with a rotator activator element (78) arranged to cooperate with said guide element (80) for turning said rotator (82), upon movement of said medicament delivery member guard (64) to the retracted position, and wherein, upon movement of said medicament delivery member guard (64) back to the extended position, said rotator activator element (78) will engage said medicament delivery member guard lock element (84, 86) and lock said medicament delivery member guard (64) in a shielding position after removal of said medicament delivery device from a medicament delivery site.

Devices and methods for a compact injector are provided with a compact configuration for ease of carrying or storage, and an activated configuration ready for injection. In the compact configuration, a plunger and a needle are both retracted into the injector housing, and upon actuation to the activated configuration, the plunger extends proximally and the needle extends distally, ready for injection. An extendable needle shield is also provided to block visibility of the needle during injection, and to reduce the risk of inadvertent needle stick at other times, including disposal.

A needle assembly for a hypodermic syringe is disclosed herein. In various aspects, the needle assembly includes a hub and a needle. A bond secures the needle to the hub, and the bond is configured to break allowing the needle to be withdrawn entirely from the hub upon application of a selected axial force to the needle, in various aspects. The axial force may be less than the tensile strength of the needle. Related methods of use of the needle assembly apparatus are disclosed herein. This Abstract is presented to meet requirements of 37 C.F.R. 1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and the related methods disclosed herein or to delineate the scope thereof.

Stabbing accidents are prone to occur to people handling needles, for example when recapping a needle or when trying to remove a needle from a syringe. A device is provided for safe and automatic removal of a needle from a syringe aimed to prevent stabbing accidents. The device is arranged to grab hold of and rotate the needle of a syringe. The needle, after being rotate off the syringe is discarded into the device by releasing the grip on the needle. The device rotates two rotating gears relative to each other to move grippers towards the needle, and rotates the two gears together to rotate the needle relative to the syringe which may be held by the user.

An injection system includes a molded body member having a body connection member at a distal end of the molded body member. The system also includes a needle hub assembly coupled to the distal end of the molded body member. The needle hub assembly includes a needle hub coupled to the body connection member of the molded body member, a needle coupled to the needle hub, and a barbed band disposed around a proximal end of the needle hub and having a barb. The barbed band allows rotation of the needle hub assembly relative to the body connection member in a first direction, while preventing rotation of the needle hub assembly relative to the body connection member in a second direction.
