A stopper retainer comprises a base having an upper surface, a lower surface, and a perimeter; a sidewall joined to the base around the perimeter, the sidewall having a raised height to define an interior cavity with the base; and a plurality of projections extending from the lower surface of the base, each of the plurality of projections being sized to at least partially fit within a lumen of a syringe barrel.

A syringe for injecting liquid medicine into a body, having its needle inside said syringe liquid holding barrel, pointed at one end of the syringe barrel which rests on user's skin when injecting, which end is sealed to hold the liquid inside the barrel of said syringe by a rubber like seal, through which seal said needle's sharp tip can exit when the needle is pressed towards the body via the other end of the barrel, which needle has conduit(s) near the other end of the needle to let said liquid into the inner tube of the needle to exit via said tip when the liquid is pressured as the needle is pushed into the user's body, which syringe can be prefilled during manufacturing, so that the syringe acts as a vial too, enabling self administration upon unpacking.

A multi-cartridge injector includes a plunger having a main brace and a pair of stems, each of the pair of stems having a coupler, a pair of stoppers coupled to each coupler of the pair of stems, a containment unit having a pair of barrels, and a Y-shaped conduit having a pair of branches and a common shaft, and a passageway that extends through the common shaft and the pair of branches, each of the pair of branches being in communication with an interior of one of the pair of barrels.

An object of the present invention is to provide a medical rubber composition having excellent non-elution characteristic and gas permeability. The present invention provides a medical rubber composition containing: (a) a butyl rubber, (b) a diene-based rubber containing polybutadiene, (c) a peroxide-based crosslinking agent, and (d) a co-crosslinking agent, wherein an amount of (b) the diene-based rubber in 100 parts by mass of the rubber component composed of (a) the butyl rubber and (b) the diene-based rubber is 15 parts by mass or more and 90 parts by mass or less, and a mass ratio ((d)/(c)) of (d) the co-crosslinking agent to (c) the peroxide-based crosslinking agent is 1.2 or more and 25 or less.

An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the SCS. The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap. Methods of flushing a vascular access device (VAD) while providing a flush syringe assembly described herein are also disclosed.

Provided is a fluid wicking tip. The fluid wicking tip includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a modular syringe system that includes a syringe and a sleeve configured to be slidably disposed over the syringe.

A syringe type ejection device capable of reducing an amount of residual liquid is provided. A syringe type ejection device includes: a barrel; a nozzle disposed to face the barrel; and a core inserted in the nozzle, the barrel having a large-diameter portion provided with a discharge space for discharging liquid, the nozzle being provided with a holding space for holding the core, the holding space being in communication with the discharge space, and the core being inserted in the discharge space.

A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.
