Abstract: A remote cannula removal cartridge syringe comprising a first barrel, a second barrel, an expandable needle hub, and a modified needle hub receiver. The second barrel is concentric with the first barrel and has a retaining pin which slides within a series of grooves of the first barrel. After use of the syringe the second barrel may be protracted causing the engagement and safe separation of the needle hub from the syringe without requiring the operator to recap the syringe or place fingers near the contaminated needle.

Abstract: A syringe device has a vial for medicaments having a first open end at a sealed second end. The first end having a plunger tip for sealing the end and has a finger grip means mounted adjacent the first. The needle and hub is slidably mounted on a needle on the second end in axial alignment with the sealed end to position said needle for access to the vial. The plunger rod has a first engagement on one end for engagement with the plunger tip and mounting means for detachably mounting the plunger between the finger grip and the hub to prevent access to the vial when the plunger is mounted thereon.

Abstract: A vial of liquid removably attachable to a syringe. In one embodiment, a luer-loc-tip is integrally mounted to the vial which is removably mountable to a syringe for withdrawing liquid from the vial without the presence of a needle. In an alternate embodiment, the luer-loc flange is mountable to a conventional vial by means of clamps and enclosed by means of a sealing cap.

Abstract: An inner elongated tubular member, a plurality of arms which extend through openings in the elongated tubular member and a concentric outer sleeve moveable relative to the inner tubular member for urging each of the arms into engagement with the hub of a needle attached to one end of a cartridge to lock the cartridge and its needle relative to the tubular member and form a hypodermic needle.

Abstract: An apparatus for dispensing a controlled dose of a liquid fluid such as a liquid medication includes a dispenser head which is snugly fitted over the needle-shaped end of a syringe filled with the liquid pharmaceutical and including a piston in fully retracted or drawn position. The syringe with its fully drawn piston is completely encased and protected by a tube which is connected to the dispenser head.

Abstract: A reusable dental syringe including a conventional medication filled carpule and a conventional double ended needle cannula which is to be retracted into a compact enclosure to permit the safe handling and disposal of the cannula while avoiding an accidental needle stick and the possible spread of disease. The carpule is inserted into a hollow carpule adapter to engage a movable needle carrier at the distal end of the adapter. The combination carpule and adapter are loaded into the cylinder of the syringe, and the needle cannula is attached to the needle carrier to penetrate the carpule. At the conclusion of an injection, the combination carpule and carpule adapter are rotated outwardly from the syringe cylinder, and the carpule is then pulled rearwardly through the adapter, whereby to correspondingly relocate and anchor the movable needle carrier at the proximal end of the adapter.

Abstract: The device for collecting blood specimens by venipuncture for laboratory tests consists of a hollow support fitted with a double-ended needle at one end and a vial with a plunger that can be fitted into and removed from the cavity in the support, the vial being sealed at one end by a pierceable membrane. In a preferred embodiment a mechanical system for automatic operation of the plunger is also envisaged. The double-ended needle consists of an active needle that enters the vein, positioned eccentrically to the axis of the support, and a passive needle that punctures the vial membrane eccentrically.

Abstract: A syringe mechanism includes a pair of sub-assemblies one of which contains a pair of threaded connector elements. One such connector element slidably surrounds a plunger rod while the other is adapted to surround a tubular barrel of the other sub-assembly. Upon engagement and tightening of the threaded elements, a resilient sleeve disposed intermediate the barrel and its surrounding connector element, is axially fore-shortened or compressed and inwardly displaced to firmly interlock the two sub-assemblies with the forward end of the plunger rod disposed within the barrel.

Abstract: Hypodermic syringe holders for use in combination with disposable medicament-containing ampoules are adapted to immobilize the ampoules within the syringe holder so as to provide manual aspirating capability.

Abstract: A one-time-use, disposable hypodermic syringe assembly in pre-packaged, pre-injection arrangement is provided and comprises: a plastic syringe barrel with a hypodermic needle mounted in its forward injection delivery end, the injection point of such needle projecting outwardly and forwardly of the barrel and the butt end of such needle projecting rearwardly within the barrel; a medicament-filled ampule positioned within the syringe barrel and having a pierceable diaphragm closure at its forward end and a piston-type stopper at its rearward end; and a plunger removably mounted on the outside of the syringe barrel and providing means while so mounted for locking the ampule, at its diaphragm closure end, out of piercing contact with the rearwardly extending butt end of the hypodermic needle, the plunger having means for connecting with the piston-type stopper of the ampule for use in moving the ampule, after removal of the plunger from its ampule-locking position on the syringe barrel, forwardly to effect pierci

Abstract: The invention relates to a hypodermic syringe comprising a cartridge having connected thereto an injection needle, a medicament holder closed by means of a piercible stopper, and a telescopic assembly which detachably connects the cartridge and the holder. The part of the injection needle extending within the telescopic assembly is surrounded entirely by a sheath of a flexible material the closed end of which bears against or is present at a short distance from the stopper of the medicament holder.

Abstract: This invention relates to an injector with a cartridge for a liquid medicine, which is suitable as a throwaway type or a re-use type, and especially displays remarkable effects at urgent occasions. This injector substantially comprises an injector tube housing a cartridge into a body thereof and a cylinder slidably supporting a piston such that it is not removed therefrom at its end portion and in the injector tube by its front half part. Further, the cartridge is equipped with a concave on its bottom and the piston is equipped with a convex on its head for engaging means. The needle portion comprises an injecting needle and a hollow needle inwardly extending from the needle. If the needle portion is urged while it is fitted to the injector tube, the hollow needle pierces the cartridge and reaches the liquid medicine in the cartridge. The cylinder is defined with a stopper at its circumferential edge to restrain the piston with respect to the cylinder.
