In a syringe or syringe capsule, particularly for micro-administration of highly viscous liquids, there are provided a zero or negative allowance between the barrel and the plunger and a low friction, resilient interface between the barrel and the plunger. There is thus provided a high pressure-resistant seal which, nevertheless, permits manual operation of the syringe with a reasonable amount of force.

A tip assembly for a syringe wherein the assembly includes a cylindrical main body having an open forward end and a partially closed back end. The inner surface of the main body adjacent the back end has an annular seal. An inner cylindrical body is positioned within and coaxial with the main body forwardly of the annular seal. A flange-like member connects the inner body to the main body to retain the inner body in spaced relation within the main body. A cap is provided for closing the open end...

The container of the present invention for storing and shipping syringes comprises a base with a plurality of ports, each adapted to receive a syringe, and a cover which fits over the syringes and locks onto the base. The base is made of insulative material so as to protect the medicinal fluid within the syringes from temperature extremes. The cover is transparent for easy identification of the contents. The sidewalls of the cover are corrugated to provide strength to the cover. The top of the c...

A cartridge for a prefilled hypodermic syringe of the type sealed at its forward end with a destructible diaphragm is provided with a piston-piston rod assembly in which the piston of resilient material is molded in the form of a hollow cylinder and has an auxiliary short, cup-shaped member of reduced diameter coaxially enclosed within its forward end, and sealed in yieldable engagement with the inner walls of said hollow cylinder by a transverse, annularly-shaped elastic membrane. The piston ro...

A receptacle includes a first recess for receiving the anterior end of the barrel of a conventional double ended needle blood collection tube holder to stabilize the holder during threaded disengagement of the needle. A post disposed within the recess includes a slot for receiving a rib of the double ended needle hub to prevent rotation of the hub while the holder is rotated to unthread the hub. Upon threaded disengagement, the needle drops into the receptacle, which drop may be augmented by a l...

An assembly (20) of syringes (22) includes a first layer (32) enclosing the syringes. The first layer maintains the syringes in an orientation where some of the syringes have a first, larger end aligned with the second, smaller end of the remainder of the syringes. The first layer also protects the syringes from outside contaminants. A second layer (34) encloses the first layer and protects it from outside contaminants. The syringes and the first layer preferably are sterilized within the second...

A needle-hub assembly on a hypodermic syringe sealed at its open end by a sealing disc, the improvement wherein the needle and hub are displaced from a normally relaxed position to a tensioned position in response to movement to remove a needle cover from the assembly and wherein the needle and hub are thrust in the direction toward the sealing disc to pierce the sealing disc upon continued movement for removal of the cover.

A medical syringe comprises a cylindrical barrel 1 having therein a plunger 4 which can be axially driven by a plunger rod 3. The plunger rod 3 passes through an aperture in the centre of a finger grip 2 having two finger grip projections 2b at opposite sides thereof. A data carrier means in the form of an electrically or magnetically operable device 2c is mounted near the end of one of the two finger grip projections 2b, with preferably a device 2c mounted near the end of each finger grip proje...

A device for encapsulating plastic waste such as plastic syringes with attached needles, lancets or blood test strips, having a melt chamber to receive the waste, means to elevate the temperature within the melt chamber, a reciprocating compaction head to compact the melted waste to form a plastic slug with the needles encapsulated within the slug, where the compaction head has a shoulder whereby the slug becomes attached to the compaction head when hardened. The hardened slug is then removed fr...

A device for the sterilization and encapsulation of bio-hazardous materials, especially including needles and syringes, which provides a sealable container to receive the materials and a rotating carousel to successively position the container for processing, a heat device to raise the temperature within the container to sterilize the contents and melt any plastic material, a compactor to crush the container into a smaller volume, and an ejector to remove the compacted container from the carouse...
