A valve comprises a first housing including a first lumen extending therethrough and defining a first disk-facing surface and a second housing including a second lumen extending therethrough and defining a second disk-facing surface, the second housing being mated to the first housing so that the second disk-facing surface faces the first disk-facing surface in combination with a flexible disk gripped between gripping portions of the first and second disk-facing surfaces, the disk including a slit extending therethrough which, when acted upon by a fluid pressure of at least a predetermined threshold level opens to permit fluid flow between the first and second lumens and which, when acted upon by a fluid pressure less than the threshold level remains sealed preventing fluid flow between the first and second lumens and a relief well between opposing portions of the first and second housings radially outside the gripping portions, a width of the relief well exceeding a width of a radially outer portion of the flexible disk so that the radially outer portion of the disk is free to move therewithin.

A check valve includes a pot-shaped valve body. The valve body has a lateral wall, a bottom wall, and an opening opposite the bottom wall. The valve body includes an elastic material. The elastic material is cut along a cut. The elastic material includes a material processed by liquid injection molding.

A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) a pumping chamber between the inlet and outlet and configured to be compressed and decompressed to pump fluid, (iv) a first one-way valve positioned on a first side of the pumping chamber, (v) a second one-way valve positioned on a second side of the pumping chamber, and (vi) an adjustable inlet lock configured to selectively prevent fluid movement through the inlet, and wherein the tube is configured to extend from the inlet of the valve assembly to the person's body cavity.

A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) one or more one-way valves positioned between the inlet and outlet that are each configured to open and close based on fluctuations in pressure between the person's body cavity and the one-way valve, and (iv) an adjustable outlet lock configured to selectively prevent fluid movement through the outlet.

A valving device includes a body with an inlet, an outlet and an internal fluid path extending from the inlet to the outlet. Within the internal fluid path, the valving device has a valve mechanism with an open mode that allows fluid flow through the valve mechanism between the inlet and outlet and closed mode that prevents fluid flow through the valve mechanism. The valve mechanism has a first surface facing the inlet and a second surface facing the outlet. The body at least partially defines a flow corral. The flow corral(s) is/are located distal to the valve mechanism and redirect fluid passing through the valving device back toward the second surface of the valve mechanism to flush the underside of the valve mechanism.

A cannula for the circulation of a fluid in an artery, includes a main lumen conveying a volume of fluid towards a first distal end; an accessory lumen including at least one inner portion arranged inside the main lumen, including: a proximal end situated downstream from the proximal end of the main lumen so as to capture a fraction of the flow of fluid entering the main lumen; a bent portion modifying the direction of flow of the fluid flow captured by the accessory lumen with respect to the direction of flow of the fluid emerging from the first end; a second distal end situated upstream from the first distal end of the main lumen, emerging on a side opening of the cannula so as to direct the captured fraction of liquid in the modified direction of flow.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that are configured to be implanted within a patient. The apparatuses, systems, and methods may include a catheter configured to implant within the intraperitoneal space of the patient, an interior flow lumen, and at least one opening connected to the interior flow lumen for therapeutic agent delivery.

A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise a pressure relief valve that opens when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

A medical connector may include a body having an outer surface and an inner surface defining a lumen of the body, an inlet port defined at a proximal end of the body, and an outlet port defined at a distal end of the body. The medical connector may further include a compressible valve member comprising a normally closed slit and disposed in the lumen and extending through the inner and outer surfaces of the body to an exterior of the medical connector. The compressible valve member may be configured to compress radially inward to open the slit upon insertion of the body into a medical access device, and expand radially outward to close the slit upon disconnection of the body from the medical access device.

A breakaway medical tubing connector includes a first side member comprising a first housing having an inner wall, a first channel disposed within the first housing, and a first valve disposed within the first channel, wherein the first valve is an active valve and wherein the first valve comprises a diaphragm forming a first seal with the inner wall. The apparatus includes a second side member comprising a second housing, a second channel disposed within the second housing, a second valve disposed within the second channel, and a cannula extending from the second side member toward the first side member. The apparatus further includes a toric joint between the cannula and the first side member, wherein the toric joint forms a second seal between the first and second side members.
