Abstract: A clamp is provided. The clamp includes a flexible uniform body. The flexible uniform body includes an aperture configured to allow a tubing to pass through the flexible uniform body. The aperture is configured to allow unrestricted flow of a fluid within the tubing when the tubing is at a first position of the aperture and restrict the flow of the fluid within the tubing when the tubing is at a second position of the aperture. The flexible uniform body includes an engageable coupling mechanism disposed at a first portion of the flexible uniform body. The coupling mechanism is configured to, when engaged, cover at least a portion of the release point of the aperture such that the tubing is locked in place within the pinch point of the aperture.

Abstract: A needleless connector may include a housing having an inlet port, an outlet port, and an inner surface defining an internal cavity extending between the inlet and outlet ports, and a compressible valve reciprocally disposed within the internal cavity. In a closed state, a top section of a head portion of the compressible valve may have a planar shape configured to contact and seal against the inner surface of the housing. In an open state, where the compressible valve is subject to an axial force, the top section of the head portion may be lodged between two pinch points between opposing walls of an inwardly angled portion of the internal surface. Additionally, in the open state, the top section of the head portion may have a non-planar shape defining a fluid path extending at least partially between opposing walls on an outwardly angled portion of the internal surface.

Abstract: A medical device includes a body configured to receive and secure an IV tube that is configured to allow for the transportation of a fluid. The medical device includes a pump mechanism including a first element positioned along a first axis and configured to move in a first direction along the first axis to compress the IV tube. The pump mechanism includes a second element positioned along a second axis perpendicular to the first axis and configured to move in a second direction along the second axis and perpendicular to the first direction to provide a force against a side of the IV tube. The pump mechanism includes a third element positioned along the second axis opposite the second element and configured to move in a third direction along the second axis opposite the second direction to provide a force against another side of the IV tube.

Abstract: A self-flushing connector includes a housing having a cavity, a first inlet port, a second inlet port, and an outlet port. A collapsible valve is disposed within the cavity. A first flow path extends from the first inlet port to the outlet port. The first inlet port and the second inlet port are fluidly connected through a gap defined between the body of the collapsible valve and an inner wall of the housing defining the cavity. A second flow path extends from the second inlet port to the first flow path. When the collapsible valve is in a closed state, the collapsible valve fluidly disconnects the second flow path from the first flow path while allowing fluid to flow through the first flow path. When the collapsible valve is in an open state, the second flow path is fluidly connected to the first flow path.

Abstract: A connector is disclosed that includes comprising a body having a tubing portion, a luer portion axially opposite the tubing portion and connected thereto, and an inner circumferential surface defining an internal bore of the connector. The inner circumferential surface extends axially between the tubing portion and the luer portion, and the internal bore being is in fluid communication with the tubing portion and the luer portion. The inner circumferential surface includes a plurality of splines extending axially along a length of the inner circumferential surface in the tubing portion of the connector. The inner circumferential surface is configured to engage an external surface of a tubing in a coupled configuration. In the coupled configuration edges of the splines grip and engage the external surface of the tubing to retain the tubing in the body.

Abstract: A coupler may include a coupler body including a first end, a second end, an outer surface, an inner surface defining a cavity, and a wall defined between the inner and outer surfaces, a plurality of first retaining fingers disposed adjacent to the first end and extending radially inward into the cavity, and a mounting aperture defined between a free end of each first retaining finger and the wall. The cavity may be configured to receive a first connector and a second connector. The plurality of first retaining fingers may be radially biased inward toward the cavity and configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The mounting aperture may be configured to receive a pivot shaft of the collar to pivotally couple the first connector relative to a central axis of the coupler body.

Abstract: A method of manufacturing a check valve may include forming an upper housing as cylindrical body with (i) an internal surface including an upstream internal surface and a downstream internal surface having a projection and (ii) an external surface, forming a T-shaped filter member and mounting the T-shaped filter member in the internal surface of the upper housing. The method may further include forming a lower housing with a support portion at a central portion thereof, mounting a flexible valve member on the support portion, and coupling the upper housing with T-shaped filter member mounted therein onto the lower housing with flexible valve member mounted therein such that the T-shaped filter member is disposed upstream of the flexible valve member.
