This disclosure includes syringes, kits containing the same, and related methods. Some syringes are pre-loaded with paste and have a syringe body defining a reservoir having an internal first transverse dimension, a paste disposed within the reservoir, the paste having a solids concentration of greater than 50 mg/mL, a needle defining a lumen having an internal second transverse dimension that is smaller than the first transverse dimension, the needle configured to be in fluid communication with the reservoir to allow intracutaneous delivery of the paste, and a plunger and/or piston disposed within the reservoir and configured to be moved to dispense paste from the reservoir through the lumen. Some syringes include a fitting (e.g. Luer fitting) disposed on the syringe body and in fluid communication with the reservoir and a sealing cap disposed on the Luer fitting to seal the reservoir.

An attachment for a syringe, carpule, or the like, includes a distal end and a terminal extension with an outer surface, a free end, and a depression introduced at a spacing into the outer surface. The attachment includes an annular base body and is placeable onto the extension. The base body encloses a free space into which the extension is introducible. The base body contains two materials a first material which is dimensionally stable and a second material which is softer than the first material and deformable. The base body has an engagement region, which engages into the depression. The extension is thus characterized in that the base body has, along an imaginary circumferential line, a first region with the first material and a second region containing the second material. The second material deforms into the depression in a placed-onto-the-extension state. The second material is embedded into the first material.

A drug administration instrument including a syringe including: a tubular surrounding periphery portion forming a drug chamber configured to store a drug; a discharge part disposed at a first axial end of the surrounding periphery portion; and a flange portion disposed at a second axial end of the surrounding periphery portion; and a sheath member having a tubular shape, surrounding an outer circumference of the surrounding periphery portion of the syringe, and holding the syringe. The sheath member includes a fitting part configured to support at least one of the surrounding periphery portion and the discharge part of the syringe.

The present invention relates to a displacement device, DD, for providing a displacement of a syringe closure system for a syringe relative to the syringe, a testing device, TD, and a method for leakage testing of a connection of a syringe closure system for a syringe with the syringe.

A stab-resistant syringe needle with an elastic protective cap and a stab-resistant syringe are provided, which include the elastic protective cap. After the syringe is used to complete injection, the protective cap can be automatically ejected through simple operations to shield a steel needle, so as to achieve a purpose of preventing stab wounds.

A syringe assembly includes a syringe body, needle assembly, retaining clip, gasket, needle latch, and needle hub. The syringe body has a syringe interior, longitudinal axis, proximal and distal ends, and needle attachment interface disposed at the distal end thereof. The gasket is configured to be compressed to provide a liquid-tight seal around an outer diameter of the needle assembly and the distal end of the syringe body. The needle latch assembly includes first and second latching tabs configured to retain the needle assembly in a close state and to be plastically deformed to an open state to release the needle assembly, and a gasket backstop configured to provide a flat surface for compression of the gasket, where the first and second latching tabs are spaced apart from the gasket such that neither of the first and second latching tabs contact the gasket during compression of the gasket.

Disclosed is a cover for an injector having a needle, a needle cap, and a needle cap remover, the cap remover being a coupler for a needle cap and a user handle, the user handle having a protruding element opposite the coupler, the protruding element having a short dimension and a long dimension, the cover comprising: at least one adhesive layer covering a surface of an outside of the injector; at least one liner layer, covering the adhesive layer, an extension extending beyond the surface; a first aperture through the adhesive layer and the liner layer aligned to an opening in the surface, the first aperture sized and shaped for passage of the coupler therethrough; and a second elongated aperture, through the extension, having a length being shorter than the short dimension and shorter than the long dimension of the protruding element.

This medical container forms a reservoir for containing a medical product and has a longitudinal distal tip extending along a longitudinal axis. The distal tip defines a passageway in fluid communication with said reservoir. The distal tip includes a fitting portion configured to fit with a connector, and a mounting portion proximally located relative to said fitting portion and configured to slidably connect an adaptor to said distal tip. The mounting portion is configured to allow a free longitudinal movement of the adaptor relative to the distal tip when the adaptor is connected to the distal tip.

A closed system transfer device (CSTD) includes a barrel, a plunger, and a connecting port fixed to the barrel. The barrel includes a first cavity and a second cavity, which are separated. A piston of the plunger is operably moved within the first cavity and divides the first cavity into a first region and a second region that communicates with the second cavity. The connecting port includes a first channel communicating with the first cavity and a second channel communicating with the second cavity. When the CSTD is connected to a drug-liquid container to draw liquid, the first region is enlarged to draw the liquid into the first region from the container through the first channel. Simultaneously, the second region is reduced to discharge air in the second region to the container through the second cavity and the second channel. Thus, the CSTD and the container form a closed environment.

A needle-equipped outer tube includes a needle; a joint member that supports the needle, the needle being insert molded or thermally welded to the joint member; and an outer tube including a connection section, wherein the joint member is thermally welded to the connection section of the outer tube.
