PATIENT FLUID LINE ACCESS VALVE ANTIMICROBIAL CAP/CLEANER

Cap and cleaning devices antiseptically maintain patient fluid line access valves to minimize the risk of infection via catheters. The devices have a cap that may contain a dry pad impregnated with an antimicrobial agent. The cap covers the access portion of the access valve when not in use. The devices have a hood that contains a wet pad impregnated with a cleaning solution and, optionally, an antimicrobial agent. The wet pad cleans the access portion of the access valve prior to and optionally, after the access valve is utilized to access the patient fluid line.

Bidirectional medical valves

A medical valve can include a housing that includes a sidewall and defines a chamber. The medical valve can include a septum coupled to the housing. The septum can include a proximal surface and a selectively openable closure positioned within the chamber. The medical valve can further include a plurality of projections that extend away from the sidewall and are configured to contact the proximal surface of the septum to oppose movement of a restricted portion of the septum in a proximal direction such that an aspiration cracking pressure required to open the closure to permit fluid flow through the septum in the proximal direction exceeds an infusion cracking pressure required to open the closure to permit fluid flow through the septum in the distal direction.

Flanged sealing element and needle guide pin assembly for a fluid infusion device having a needled fluid reservoir

A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.

Neutral pressure split septum luer access device

A neutral pressure split-septum luer access device is described for receiving a luer lock connector. The septum has a plurality of elastomeric columns projecting laterally within a chamber. Each elastomeric column is under sufficient compression so that the columns are bowed and the column strength is reduced by bowing, but the slit sealing force is high. This configuration places the lower portion of the slit in a tightly sealed configuration which is never-the-less receptive to penetration by the male luer which causes the columns to bow further and collapse precipitously with the elastomeric force of the collapsing mass of the columns being carried distally to displace and pop open the central slit distal the tip of the male luer. The septum further provides a transverse separation between the columns and a distal sealing portion so the force of the displacement force to the sealing portion is reduced.
