An airtrap for a medical or physiological fluid in one embodiment includes a conical housing having a radius that increases from its top to its bottom when the housing is positioned for operation; a medical or physiological fluid inlet located at an upper portion of the conical housing; a medical or physiological fluid outlet located at a lower portion of the conical housing, the inlet and the outlet positioned and arranged so that medical or physiological fluid spirals in an increasing arc around an inside of the conical housing downwardly from the inlet to the outlet; and a gas collection area located at an upper portion of the conical housing. In another embodiment, the airtrap is shaped like a seahorse having a head section and a tail section. Any of the airtraps herein may be used for example in blood sets, peritoneal dialysis cassette tubing, and drug delivery sets.

Airtrap, system and method for removing microbubbles from a fluid stream

A peritoneal dialysis catheter includes: a catheter tube defining a lumen for carrying peritoneal dialysis fluid to at least one aperture located at or near a distal end of the lumen; at least one cuff located along the outside of the catheter tube; an access site proximally spaced from the at least one cuff, the access site allowing an antimicrobial agent to be introduced into the catheter tube; a reservoir operable with the catheter tube and in fluid communication with the access site, the reservoir storing an amount of the antimicrobial agent received from the access site after an antimicrobial agent introducer is removed from the access site; and a delivery area of the catheter tube in fluid communication with the reservoir, the delivery area positioned so as to target delivery of the antimicrobial agent to the at least one cuff or other desired location along the catheter tube.

Drug diffusing peritoneal dialysis catheter

A dialysis system instrument includes a dialysis instrument, a disposable pumping and valving cassette apparatus operable with pumping and valving actuators of the dialysis instrument, the disposable cassette including an electronic cell and electronics associated with the electronic cell, the electronics configured to determine an electrical property of a solution flowing through the electronic cell of the disposable apparatus.

Dialysis fluid measurement systems using conductive contacts

A port assembly includes a valve housing with an inlet opening, a valve disposed in the valve housing to control access through the inlet opening, and a base joined to the valve housing and having a bore therethrough. The bore has a closed end defined by a frangible barrier, and a pushrod is disposed in the bore between the valve and the frangible barrier, axial movement of the pushrod causing rupture of the frangible barrier. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit is defined, at least in part, by a port assembly.

Port assembly for use with needleless connector

A port assembly includes a housing with an opening and a bore therethrough, a slit septum disposed in the bore to control access through the opening, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum and a second end aligned with the membrane, and a resilient member disposed between the perforator and the base. The port assembly may be used in a fluid container that includes a receptacle for retaining a fluid, and at least one conduit in communication with the receptacle. The at least one conduit may be defined, at least in part, by the port assembly.

A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.
