  • Publication number: 20190078714
    Abstract: The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. In embodiments, a coupling device may be configured according to lookup table that defines compatible configurations of connectors. The configurations may be based on the presence and absence of interference members at standardized locations on the respective connectors. The interference members may include posts that mechanically interfere with other posts, but can be inserted into holes when two connectors have a compatible configuration.

  • Patent number: 10221975
    Abstract: The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. In embodiments, a coupling device may have multiple male connectors, female connectors, open ports, butt connectors, and plugs that close off various ports and connectors. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are properly joined and/or sealed by plugs. If any of the connectors is not properly mated to a corresponding one or not sealed by a plug on the opposite connector, the coupling will leak, since the connectors are joined to a furcating channel.

  • Publication number: 20180318491
    Abstract: A tubular medical fluid flow set comprises a pressure sensing chamber connected in flow-through relation to fluid flow tubing of the set. The pressure sensing chamber defines a movable, flexible, impermeable diaphragm dividing the chamber into two separate compartments. The fluid flow tubing communicates with one of the compartments and is isolated from the other of the compartments. A port is carried on the chamber, the port having a seal therein, and communicating with the other of the compartments. Thus, the other of the compartments is hermetically sealed until the port is opened for connection with a pressure measuring device, to keep the flexible diaphragm in a desired, initial position prior to opening of the seal.

  • Patent number: 9879807
    Abstract: The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. A coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are property joined. If any of the connectors is not property mated to a corresponding one, the coupling will leak. The coupling devices are made unique by providing an arrangement the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating of one or more of the connectors and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.

  • Patent number: 8674165
    Abstract: A pad of elastomeric material having a softness of no more than about durometer 30 Shore 00. The pad may carry adhesive for adhering the pad to a surface, either directly or indirectly through an envelope which surrounds the pad and carries the adhesive. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.

  • Patent number: 8664465
    Abstract: A pad of elastomeric material having a softness of no more than about durometer 50 Shore 00. The pad may carry adhesive and/or a housing for adhering the pad to a surface, either directly or indirectly through an envelope which surrounds the pad and carries the adhesive. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin.

  • Patent number: 8647312
    Abstract: A medical device has an interior for containment of fluids; an opening into the interior, an elastomeric wall comprising a fixedly placed, flexible barrier across the opening; and a retention wall positioned adjacent to a peripheral portion of the elastomeric wall. The retention wall defines a central opening and has a generally rigid retention zone surrounding the central opening, to engage and retain a connector tube which is advanced into the central opening to open a flow aperture through the elastomeric wall, for flow through the wall and connector tube. One of the retention zone and connector tube may be made of a material of sufficient hardness that material of the other engaging member is deformed by engagement therewith, which increases the strength of retention between the retention wall and the connector tube.

  • Patent number: 8641684
    Abstract: A closure for a tubular access port in a medical fluid flow line or other container comprises a removable cap for enclosing and sealing the tubular access port. The cap has a closed end wall. The end wall carries an extending poker to facilitate the pushing of an antiseptic-carrying material into a lumen of the access port. The poker has an outer diameter that is less than the inner diameter of the access port. A method of using the poker is also described.

  • Patent number: 8592639
    Abstract: A pad of elastomeric material having a softness of typically no more than about durometer 50 Shore 00. The pad may carry adhesive and/or a housing for adhering the pad to a surface, either manually, or by adhesive tape, or another strap. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.
