Septum Patents (Class 604/88)
  • Patent number: 5380281
    Abstract: The device comprises a tubular housing with two jackets and a container filled with the liquid component of a drug. Within the inner jacket of the housing, close to the closed end thereof, is a chamber containing the powdered components of a drug. A needle for piercing the stopper which closes the container enables the interior of the container to be put in communication with the chamber so as to allow the liquid component to flow out and consequently mix with the powdered component. The subsequent advance of the container into the housing, with the consequent penetration of the piston into the container, causes the further flow of the liquid component into the chamber carrying the drug solution to the exterior of the device generally like a syringe. Its use as a supplier of infusions is also foreseen.

  • Patent number: 5370636
    Abstract: In a plug-type connector having two plug parts for producing and interrupting a flow connection, in order to enable sealing of the flow branches of the respective parts when separated from one another when the flow connection is interrupted, each plug part is terminated with a perforable septum with a cannula held so as to be longitudinally displaceable in one septum. The cannula and the septa are fashioned with reference to one another such that the septum holding the cannula offers lower resistance to the cannula upon penetration than does the other septum. This results in the cannula first penetrating the septum that holds it when the plug parts are joined and subsequently penetrating the other septum. When releasing the plug parts from one another, the cannula is first withdrawn from the septum that holds it and is then withdrawn from the other septum.

  • Patent number: 4886495
    Abstract: 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.

  • Patent number: 4861335
    Abstract: A syringe provides for the isolated storage of two components of a medicament until immediately prior to use of the syringe. One liquid component is stored in a collapsible chamber of a sealed capsule within a hollow plunger stem of the syringe, and the other component beneath the head of the plunger. A double headed needle arrangement between the head and stem of the plunger is caused to penetrate the plunger head and the capsule when the syringe is to be used so that the plunger may be drawn back to exhaust the contents of the capsule chamber into admixture with the component stored beneath the head of the plunger. Communication through the double headed needle arrangement is then interrupted before the plunger is used to eject the syringe contents through an external needle fitted to the syringe.

  • Patent number: 4808184
    Abstract: A method of preparing a self-curing two-component cement, which is particularly useful for the preparation of bone cement used in orthopedics, from a powder component and a liquid component. The method includes providing the powder component in a first at least partially evacuated inflexible container, providing the liquid component in a second inflexible container, and adding the liquid component to the evacuated powder component, such that the liquid floods the evacuated interspaces between the powder particles. An apparatus for carrying out this process is a syringe with a slidable piston, the syringe being sealed at its dispensing end by a removable plug. Preferably, the syringe is fitted with an axially collapsible spiral mixing device, one end of which is an elongated shaft which extends through the removable plug at the dispensing end. The elongated shaft can be rotated to homogenize the contents of the syringe, but during dispensing the mixing device collapses as the piston advances.

  • Patent number: 4781679
    Abstract: The invention is an integral container system designed for separately storing a liquid, such as a diluent, and a second substance, such as a medicament, and subsequently adding the second substance to the liquid in a simple and sterile operation. In one embodiment, a flexible I.V. bag is provided with a second substance dispensing cup containing a powdered medicament, which cup fits slidably in a sleeve passing through the walls of the bag. Fitted in the open end of the cup is a pierceable plunger. A hollow needle is held in position to pierce the plunger when the cup is pushed toward the needle. The needle is slidably held so that when it is pushed by the plunger, it will also pierce a diaphragm fitting over the sleeve. When both the plunger and the diaphragm are pierced, fluid access between the cup and the bag is had through the hollow needle. Diluent can then be injected into the cup to dissolve or slurry the powdered medicament.

  • Patent number: 4769026
    Abstract: A syringe purging device comprises a liquid-tight chamber into which air and/or any excessive amount of a hazardous liquid, such as a chemotherapy drug, is ejected from a syringe to overcome the health hazard created by openly purging syringes into the air or into a pad of gauze material. A sharp open end of a hollow needle of a syringe is sealingly inserted into the liquidtight chamber, and the syringe is activated to purge any air and/or excess liquid into the chamber. The liquidtight chamber may be closed, with any liquid ejected thereinto being retained by absorption into a wad of absorbent material contained within the chamber. Alternately, the chamber may be vented to the atmosphere through a hydrophobic filter such that air injected into the chamber passes through the filter, but any liquid is retained within the chamber since it cannot pass through the hydrophobic filter.
