Abstract: Peristaltic pumps are described herein. In certain embodiments, a peristaltic pump includes a plunger and a feeler pin. The plunger is movable to selectively engage a pumping volume of a tubing segment to expand the pumping volume to draw fluid flow into the pumping volume and to contract the pumping volume to conduct fluid flow from the pumping volume. The feeler pin extends through the plunger and movable to maintain contact with the tubing segment, wherein the feeler pin is movable in response to a height of the pumping volume.

Abstract: A device for coupling to a fluid connector of an IV administration set to resist contamination of the fluid connector and IV administration set and permit priming of the IV administration set. The device including a cover body having a cavity for receiving the fluid connector, a priming passage for priming fluid from the IV administration set through the fluid connector, and a coupling tab extending from the cover body, the coupling tab permitting the cover body to be coupled to a length of an IV line or other portion of the IV administration set to resist contamination and permit priming of the IV administration set.

IPC: A61M39/22
Abstract: A needleless connector may include a housing comprising a central longitudinal axis, a body portion, and a base portion. The body portion may include an inner surface forming an internal cavity, and a first port forming a first fluid passage to the internal cavity. The base portion may include a top section including a valve seal support, and a bottom section including a second port forming a second fluid passage to the internal cavity. The needleless connector may further include an asymmetrically-shaped valve disposed in the internal cavity. The asymmetrically-shaped valve may include a head portion, a valve body portion extending distally from the head portion, and a wall having an inner surface forming a valve cavity. The valve may be coupled with the housing such that the inner surface of the valve at the valve body portion is seated and radially supported on the valve seal support.

Abstract: Medical fluid extension set systems are disclosed that can include a tubing anchor coupled to tubing and a fluid coupling device, and can be anchored to a patient to resist unintended separation of the tubing anchor or a catheter coupled to the tubing, from a patient, and to permit separation or disconnection of a fluid pathway between the tubing and another device coupled to thereto upon exceeding a pulling force on the fluid coupling device, and where disconnection includes separation of first and second valve assemblies such that a fluid pathway of the first and second valve assemblies is obstructed upon disconnection of the fluid coupling device.

Abstract: A tubing junction assembly may include a body, and a collar coupled to the body. The body may include a head portion, a base portion, and an intermediate portion. At least a portion of an outer surface of the body at the intermediate portion may define a cross-sectional width that tapers from the head portion to the base portion. The collar may have an inner surface defining a passage. A tubing may be stretched over the outer surface of the body with a proximal end portion of the tubing stretched over at least a portion of the outer surface of the body at the intermediate portion. The inner surface of the collar may be sleeved over a portion of the outer surface of the tubing and coupled to the collar such that the proximal end portion of the tubing is sandwiched and compressed between the body and the collar.
