Abstract: A fluid delivery Y-site is described that is configured to receive and control delivery of two or more fluid flows. Fluid flow is controlled within a chamber by a valve and float. Flow of a primary fluid into the chamber is reduced or halted by the movement of a valve. The valve may occlude a first flow port into the chamber in response fluid flowing from a second flow port into the chamber. A float is moveably disposed within the chamber and configured to engage the valve in response a fluid flow into the chamber from the second flow port. As fluid flow from the second flow port into the chamber is reduced or ceases, the valve and float allow the flow from the primary flow port to once again enter the chamber and exit from an outlet port.

Abstract: A drip chamber is described that is used in medical infusion therapy, wherein the drip chamber utilizes valving to control flow of one or more fluids to a patient. The drip chamber includes a body forming a chamber, wherein fluid may enter via two or more flow ports, and an output port, where fluid may exit the chamber. A float controls fluid flow through one or more flow ports into the chamber such that the flow exiting the chamber may be limited to a single fluid or a combination of the fluids entering the chamber. The float is configured to be retained within the chamber, and the float moves within the chamber based on a level of fluid within the chamber. The control characteristics of the float are determinable by attributing specific buoyancy and dimensions to the float.

Abstract translation: 描述了用于医用输液治疗的滴注室，其中滴注室利用阀来控制一种或多种流体流向患者的流动。 滴水室包括形成室的主体，其中流体可以经由两个或更多个流动端口进入，以及输出端口，其中流体可以离开室。 浮子控制流体通过进入腔室的一个或多个流动端口的流体，使得离开室的流可以被限制到单个流体或者进入腔室的流体的组合。 浮子被构造成保持在腔室内，并且浮子基于腔室内的液体水平在腔室内移动。 浮标的控制特征可以通过将特定浮力和尺寸归因于浮动来确定。

Abstract: A needleless connector may include a housing having a proximal end, a distal end, and an inner surface defining an internal cavity extending between the proximal and distal ends. A compressible valve may be disposed within the internal cavity. The compressible valve may include a head portion, a flange portion for securing the compressible valve in the housing, and a body portion extending between the head portion and the flange portion. The body portion may include a cylindrical outer surface having an external notch extending along a portion of a circumference of the cylindrical outer surface and recessed radially-inward from the cylindrical outer surface. The body portion may further include a planar face extending distally from the external notch and disposed between the external notch and the flange portion. The planar face may be recessed radially inward relative to at least a portion of the cylindrical outer surface.

Abstract: Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

Abstract: Drip chambers are described herein. A drip chamber comprises an inlet, an outlet, and a chamber body. The chamber body defines a chamber volume in fluid communication with the inlet and the outlet. The chamber body is movable between a collapsed configuration having a first volume and an expanded configuration having a second volume. The second volume is larger than the first volume, and the chamber body is configured to be moved from the collapsed configuration to the expanded configuration to draw in a medical fluid from the inlet into the chamber volume to prime the drip chamber.
