  • Patent number: 4823833
    Abstract: The present invention provides a sterile, unitized, economical device furnishing a fluid path between a plurality of solutions to be compounded and a receiving container. The device includes a plurality of fluid connectors and fluid lines sealingly connected to respective pump fittings which provide individual paths to a common junction block.The common junction block includes a portion for receiving fluid lines and preventing them from crimping thereby maintaining fluid flow. The block also includes an exit port for providing a sealingly sterile connection to the receiving container. Further, a closure is provided to protect the exit port from contamination when the port is not providing fluid communication to the receiving container.

  • Patent number: 4639019
    Abstract: A luer connection device in which a male luer connector includes an outer sleeve that is slideable up a tapered wall so that compression between the outer sleeve and the tapered wall increases as the outer sleeve moves forwardly. An outwardly extending flange is carried by the body of the male luer connector for cooperation with the outer sleeve, to enable the outer sleeve to be unscrewed from a female luer connector without relative rotation of both the main portion of the male luer connector and the outer sleeve.

  • Patent number: 4581020
    Abstract: An implantable medical device and system for percutaneous (e.g., peritoneal as well as subcutaneous) administration of a medication from an external source is disclosed. Continuous, variable rate, or intermittent administration of medication can be effected without the need for repeated puncturing of the patient's skin. The present device includes an implant that is transcutaneously anchored to the patient, an insert releasably mounted on the implant, and a seal means on the implant which seals an implant cavity that receives the insert upon removal of the insert so that the patient is protected from infection while the insert is replaced.

  • Patent number: 4538918
    Abstract: The present invention teaches a medical device which mixes a primary medication with a secondary medication before administration to a patient. The device is also capable of automatically sequentially administering the primary medication alone to the patient. The device includes a medication chamber which is reduced in volume to deliver the secondary medication for mixing with the primary medication.

  • Patent number: 4534764
    Abstract: A sequential medication delivery device for intravenous administration of plural medications is disclosed. A secondary medication can be administered to a patient followed by an automatic resumption of the delivery of the primary medication at a predetermined flow rate. The disclosed medication delivery device includes an internal valving system and an associated medication chamber that contains the secondary medication to be delivered. While the medication chamber contains such secondary medication, the flow of primary medication to the patient is interrupted. However, once the medication chamber has been substantially emptied the flow of primary medication to the patient is resumed automatically.

  • Patent number: 4432760
    Abstract: An administration set including a burette with an air valve communicating with the burette chamber. The air valve comprises a stationary port extending from a top portion of the burette chamber with a fitting closing the port except for a small passageway defined by a top portion of the fitting. A pivotable closure overlies the port and is pivotally connected therewith. The pivotable closure defines an opening for communication with the small passageway when the closure is pivoted to a predetermined open position. The closure opening and the passageway are segregated when the closure is not in the predetermined open position. A filter member is received within the port and directly underlies the small passageway.

  • Patent number: 4430077
    Abstract: A tamper indicating device (24) is connected to the inlet (14) of an injection site (10) which inlet (14) includes a pierceable, self-sealing member (16). The tamper indicating device (24) comprises a cap (26, 28) which covers the inlet (14) rendering the pierceable, self-sealing member (16) inaccessible. A first portion (26) of the cap is connected to the inlet (14) and a second portion (28) of the cap is separated from the first portion (26) by a frangible section (30). A handle (32) extends from the second portion (28) and is operable when actuated to break the second portion (28) away from the first portion (26) at the frangible section (30), rendering the pierceable, self-sealing member (16) accessible. The first portion (26) remains connected to the inlet (14) to indicate that tampering has occurred.

  • Patent number: 4175558
    Abstract: A parenteral liquid administering device includes an enlarged, liquid-holding burette-type chamber for receiving measured aliquots of liquid from a source. The burette has a bottom flow aperture with a valve controlling flow through the aperture. The valve includes a buoyant float ball and a valve seat positioned about the bottom flow aperture to receive the ball, in the absence of sufficient liquid to float it, in air-tight, sealing relation. Apertured retention means are provided surrounding the ball which are proportioned to permit it to float in spaced relation from the valve seat in the presence of liquid passing through the apertured retention means.

  • Patent number: 4133441
    Abstract: An injection site is provided which is molded inside out with inwardly extending rings. The rings have a smaller internal diameter than the external diameter of the tubular member to which the injection site is to be connected. The injection site has a central portion for receiving a needle therethrough, and a first, cylindrical portion which is extended into the tubular member. After such insertion, the portion with the attached rings is folded back onto the tubular member. The rings become positioned on the outside of the assembly and are in the compressed state squeezing tightly against the tubular member.

  • Patent number: 4084606
    Abstract: A fluid transfer device is provided for administration of medicament to a patient. The device includes a plastic housing having a first inlet, a second inlet and an outlet, and an umbrella check valve coupling the inlets and outlets. The umbrella check valve is positioned so as to permit flow from the first inlet to the second inlet and from the second inlet to the outlet, but to block flow from the second inlet to the first inlet and from the outlet to both the first inlet and the second inlet.

  • Patent number: 4048995
    Abstract: An injection site is provided in the illustrative embodiment, in which a first inlet (to which a parenteral fluid conduit is connected) and a second inlet (adapted to receive injected medication) are parallelly located on one end of a main body portion. An outlet is located on the opposite end of the main body portion, with the second inlet and the outlet being substantially coaxial. The main body portion defines a single chamber that communicates with the inlets and outlets and is constructed to provide unobstructed flow of the parenteral liquid and medication to the outlet. The chamber is of a length that aids in preventing the medication that is injected from dropping through air.

  • Patent number: 4038983
    Abstract: A flow system for infusing a fluid such as blood from a storage reservoir into the human body includes a hand-operated pump for increasing the flow rate of the fluid through the system when required. The pump includes a duckbill-type valve assembly user-conditionable to an open position wherein fluid can pass freely through the valve and air trapped in the housing of the pump can be purged upline to the reservoir, and to a closed position wherein reverse flow of fluid in the system is prevented during operation of the pump.

  • Patent number: 4027842
    Abstract: A flexible plastic hanger member for drainage bags and the like is provided comprising a body disposed in a plane; a hook for suspending the bag from one end of the body, means for engaging a hanger support extending from the body, and a holding part for supporting a portion of a length of tubing in transverse relation to the hanger support engaging means, the holding part including a flange member which is wider than said body for grasping the tubing, thus reducing the amount of kinking of the tubing, when compared with prior art structures. The hanger support engaging means is in acute angle relation to the hanger body for improved, resilient gripping of a hanger support.
