A cannula is retractably mounted with a needle holder (9) in a housing (5). A switching device (7, 8) allows the hollow needle (10) to be retracted after use into the housing (5). The needle holder (9) secures against rotation the hollow needle (10) in the housing (5) in a predetermined orientation. The housing (5) is preferably provided on its outer side with markings (13) which indicate the orientation of the hollow needle (10). The hollow needle (9) cannot twist when it is retracted. Another ...

A method and an machine for the manufacturing of syringes by vertically feeding long glass tubes to an intermittently rotary forming machine, having two horizontally rotary machine sections each intermittently rotating on a central vertical axis of a stationary machine frame, to a plurality of forming stations, each machine section having a plurality of continuously rotary gripping chucks mounted on the stationary machine frame, a plurality of burner nozzles and a plurality of forming tools, for...

Measurements of insulin quantities in a syringe are performed optically in an integrated insulin dose recorder/blood glucose meter. The syringe is placed in a holder before and after the administration of the dose. Liquid quantities in the syringe are determined by comparing optical response patterns of the syringe with calibration data stored in the device. Dose histories are downloaded to a patient computer for transfer to a clinician's computer. Standard or customized syringes (e.g. with mark...

This invention relates to a process for manufacturing prefilled syringes where at least one of the syringe components is manufactured in at least a class 100 environment. The process includes the steps of manufacturing syringe components, such as the barrel and plunger substrate, within at least a class 100 and MCB-3 environment; manufacturing syringe components, such as the plunger cover and tip seal in an environment less clean than a class 100 environment; decontaminating the plunger cover an...

A passive needle guard includes a body having a cavity therein for receiving a syringe, and a shield. The body is slidable with respect to the shield between retracted and extended positions covering and exposing, respectively, a needle extending from the syringe, the body being biased towards the retracted position. Latch members extend from the shield that include catches for engaging mating catches on the body for holding the body in the extended position. During use, the needle extending fro...

A disposable syringe divided into two units to be packed separately under sterile conditions. The first unit contains a filled cylindrical ampoule with a plug serving as piston and a pierceable seal. The other unit contains a needle, a needle cover which serves as piston rod and a holder for the needle and the ampoule. The second unit contains also a finger rest having a sleeve slidable along the ampoule to a stop on its rear end.

A safety container for storing and transporting a hypodermic syringe with attached needle, wherein the container is comprised of an elongated transparent plastic tube having a closed end and an oppositely disposed open end. The open end is fitted with a removable lid. The closed end of tube contains a rubbery pad into which the needle point of the syringe is embedded. The resilient, self-sealing rubbery pad frictionally holds the needle and syringe secure, and seals the lumen of the needle to pr...

The present invention is an improved needle cover assembly for a syringe. The needle cover assembly includes a first half and an opposite unequal second half with an arc shaped inner shell such that the first half encloses the arc shaped inner shell of the second half of the needle cover assembly. The arc shaped inner shell of the second half extends over the tip of the needle and the first half of the elongated cover member extends over both the arc shaped inner shell and the tip of the needle ...

A medical injection device including a shield system and a syringe coupled to the shield system. The shield system includes a syringe holder, a shield telescopically received in the holder and slidably coupled to the holder and an end fitting which isolates the syringe flange from the holder, preventing damage to the flange. A spring resiliently urges the shield from a retracted position to an extended position. Stop members are provided adjacent the distal end of the holder and the proximal end...
