摘要:
A system is provided for providing syringes filled with pharmaceuticals whose components must be stored separately, using an active ingredient in a pharmaceutical vial, a diluent in a protosyringe such as a bottomless vial or a cartridge, and a combiner assembly which enables the content of the pharmaceutical vial to be transferred into the protosyringe and converts it into a ready-to-use syringe on activation. The combined assembly included a tubular body having recesses at opposite ends for receiving capped ends of the vial and the protosyringe, and a hub and needle assembly between penetrable sheaths or shields which acts on activation of the assembly to enable the transfer and conversion referred to above. Components of the system may also be used to convert protosyringes and pharmaceutical vials containing pharmaceuticals into delivery systems.

The internal tubular surface of a collector can for a battery cell is processed by planing or ploughing an array of discrete portions of material out of the thickness of the can wall without penetrating the can so as to lift these portions inwardly of the surfaces, while leaving them attached to the can, to positions where they present surfaces facing both towards and away from the can. The lifted portions extend the internal surface of the can and provide couples into the active material of the cell which both physically and electrically bond the material to the extended surface. The process makes use of a segmental array of cutting elements advanced axially into the can, then moved radially to penetrate the can surface and axially or circumferentially through a cutting stroke to raise non-detached shavings on a segment of the internal surface of the can, and then withdrawn using reverse motions. Multiple segmental arrays may be used simultaneously, or the same array may be used sequentially on different segments of the surface.

A prefilled syringe for one or two component medicaments is based upon the use of a vial containing a medicament or one component of a medicament, the vial having an open bottom closed by a piston. When a flexible extension of the piston is coupled with a tubular plunger, and an adaptor cap having an internal needle and an external connection for a needle is placed over a cap of the vial, the latter is converted into a prefilled syringe. The open bottom of the vial is configured so as not to interfere with handling of the vials by conventional vial sterilizing, filling and capping machinery, and may be formed so as to provide an internal shoulder which will secure a piston retention member.

A transfer assembly for transfering a fluid to a vial, admixing the same and then returning the fluid to a cartridge, the transfer assembly having a vial gripper located at a first end and a cartridge holder at the second end of an elongated outer housing, a fluid passageway extending between the vial gripper and the cartridge holder with piercing elements being located at respective ends of the fluid passageway. In a preferred embodiment, an adaptor is mounted on the end of the outer housing where the cartridge holder is situated. The adaptor may move from a retracted to an extended position wherein it will surround the needle.

A system for the intravenous infusion of pharmaceuticals uses a syringe assembly, and a flexible tube for connection to a Y-connector in an intravenous drip assembly through which tube diluent fluid may flow from the drip assembly through the connector assembly to the syringe body, and through which diluted, dissolved or suspended pharmaceutical may pass from the syringe body to the Y-connector. The syringe assembly has an elongated body, a piston movable longitudinally within and in sealing engagement with the body, a plunger for insertion into one end of the body to move the piston, a penetrable closure at the other end of the body, and a connector assembly for establishing a passage for liquid between the interior of the body and the tube, the connector assembly comprising first and second cannulas projectable through said penetrable closure, a coupling for establishing connection between the first cannula and the tube, an air valve establishing a controlled connection to the exterior of the connector assembly, and a connection between the second cannula and the air valve.

A prefilled syringe for one or two component medicaments is based upon the use of a vial containing a medicament or one component of a medicament, the vial having an open bottom closed by a piston. When the piston is coupled with a plunger, and an adapter cap having an internal needle and an external connection for a needle is placed over a cap of the vial, the latter is converted into a prefilled syringe. The piston has an axial passage closed by a resealable septum, so that a separate diluent stored in a flexible capsule may be introduced into the vial through the piston by a double ended needle mounted on a further cap applied to the capsule, the further cap being coupled within the tubular interior of the plunger so that the double ended needle penetrates the septum in the piston. The capsule is pushed forward onto the double ended needle when its contents are to be expelled into the vial. The capsule and its cap are then removed and discarded.
摘要:
A transfer device (10) which comprises an outer housing (24), an inner body (26) formed within the housing (24), the inner body (26) having a conduit (66) extending therethrough to provide fluid communication between upper and lower chambers, the conduit (66) having a piercing tip (68) at a lower end, a cap (54)having a top wall and a downwardly extending wall (58), the cap being retained in position such that access cannot be had to the inner body (26), and a pushing member (44) which has at least one leg (48) extending upwardly, the pushing member having an activated position where the leg (48) will extend upwardly to the upper chamber and move the cap (54) such that access may be had to the inner body (26).
摘要:
A transfer device for pharmaceuticals comprising a housing which has an open bottom permitting insertion of a vial within the housing, a piercing member mounted within the housing and having an interior passageway formed therein, a connector for a syringe located on top of the housing, and a moveable member mounted within the housing, the moveable member being moveable from a first position preventing access to the piercing member and a second position permitting access to the piercing member when the vial is inserted in the housing.
摘要:
A transfer and mixing device which utilizes a by-pass cartridge and a syringe. After mixing the dry component and the diluent in the by-pass cartridge, the mixture can be passed to a syringe which includes a syringe plunger having a fluid passageway therein with a hydrophobic membrane covering the passageway. The mixture can be transferred back and forth between the by-pass cartridge and the syringe through a small bore to achieve mixing, particularly in the case of microspheres held in suspension.
