  • Publication number: 20240325707
    Abstract: Medical tube can have a continuous inner layer having a continuous outer layer thereon, in which the inner layer includes a polyolefin such as a polyethylene or polypropylene or a functionalized polyolefin. The outer layer can include a thermoplastic polymer such as one or more of, or a blend including, a thermoplastic polyurethane (TPU), a thermoplastic olefin (TPO), a thermoplastic elastomer (TPE), a styrene-containing thermoplastic elastomer (S-TPE), a polyolefin elastomer (POE), a styrenic blocking copolymer (SBC). Advantageously, the outer layer and/or the inner layer do not include polyvinyl chloride. Such tubing can be readily solvent bonded to medical connectors and used with infusion sets.

  • Publication number: 20220160970
    Abstract: Hydrophilic infusion tubes and infusion components are provided. A fluid pathway connects a first fluid port and a second fluid port, the fluid pathway formed of a base material suitable for fluid infusion and a hydrophilic fluid interfacing surface disposed on an inner surface of the fluid pathway. The hydrophilic fluid interfacing surface provides a water wetting contact angle that is less than a water wetting contact angle provided by the base material. Infusion sets are also provided.

  • Publication number: 20210187250
    Abstract: A needle tip shield may include a needle passageway that may receive a needle, a tip shield interior space that may receive a needle block, and a fluid restriction member. The fluid restriction member may be configured to restrict fluid leakage into and/or out of the needle tip shield. The fluid restriction member may be selected from the group consisting of: (1) a fluid impedance member located adjacent the needle passageway that may impede fluid from entering into the needle tip shield through the needle passageway; (2) a fluid retention member that may retain fluid within the tip shield interior space; and (3) an anti-splatter member that may inhibit fluid splatter when the needle block moves from an open position to a closed position within the tip shield interior space.

  • Patent number: 10695551
    Abstract: A catheter assembly (10) comprising a catheter (18), a needle (12) having a sharp distal tip (13), and a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (19) having a preformed opening (22) that selectively permits or blocks a flow of fluid through the catheter (18), a first inner diameter (32) that closes the valve (19), and a second inner diameter (30) larger than the first inner diameter (32), the second inner diameter (30) opening the valve (19), wherein the valve (19) is in an open position upon axially compressing the valve (19) into engagement with the second inner diameter (30) of the catheter hub (14), and the valve (19) is in a closed position upon releasing the valve (19) to engage the first inner diameter (32) of the catheter hub (14).

  • Patent number: 10105899
    Abstract: An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.
