摘要： The invention is a relatively thin wall extruded tubing that in different forms can provide flow regulation for peristaltic pumps, reduce spallation, extend pumping life, provide means to measure inlet and outlet pressure of the peristaltic pump and limits the inlet and outlet pressure generated by peristaltic pumps. A special peristaltic pump designed to take advantage of the unique characteristics of the thin walled tubing forms the new pumping system. The invention has particular usefulness in the medical industry for pumping physiological or nutritional liquids.

摘要： In the treatment of obstructive sleep apnea, a CPAP flow generator (22) is employed to direct air to a nasal mask (20) fitted to a patient. The airflow from the generator is monitored, and the flow and/or pressure is increased through signal processor (24) when the waveform of the air flow exhibits characteristics corresponding to flow limitation. The generator may be controlled to repetitively test for waveform variations, in order to adjust the CPAP flow to the minimum level that does not produce flow limitation.

摘要： A self-sealing catheter valve (1,19) includes a flexible tubular part (2) having a distal opening (6) and an opposite proximal opening (12), and a proximal valve part (5). The proximal valve part (5) has a curved self-sealing flexible diaphragm (7) disposed inside the flexible tubular part (2) and has a base perimeter (8) united with a circumferential wall (9) of the flexible tubular part (2).

摘要： A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.

摘要： A sphincter valve (11) for controlling the flow of fluid through a fluid delivery line has a body (12) molded of a unitary piece of substantially flexible silicone material. The body is formed with an outer shell (17), and interior tube (18) disposed within said outer shell, an end portion (14), a pressure chamber (21) defined between the outer shell and the interior tube. A separate end cap (13) is secured to, and closes the end (24) of the body opposite the end portion thereof. A central passageway (27) extends through the interior tube, and through the ends of the valve. In use, the valve is spliced in a fluid delivery line, and the pressure chamber is coupled to a source of selectively deliverable pressurized air. When pressurized air is forced into the pressure chamber, the inward force created by the pressure collapses the interior tube onto itself shutting off flow through the valve.

摘要： The specification describes a thin-walled pressure sensitive section (53A) that may be incorporated into a blood tubing (53) and sealed in a housing (232) to provide: an adjustable resistance to flow, adjustable positive or negative pressure relief, positive or negative pressure isolation of pressure sensitive devices (e.g. pressure monitors) from the pumped fluid, controlled recirculation between the inlet and outlet of pumps, pressure regulation, and pressure sensitive reservoirs. It also allows for a simple and accurate method to set the occlusion of roller pumps. The thin wall section (53A) enables actuation of the various devices by balancing the flow or pressure of the blood in the extracorporeal circuit against a known or determinable pressure in the housing to open, close or modulate the valve. When the device is made from one continuous length of tubing, it has special advantages for extracorporeal circuits. Also described is an electromechanical control unit that utilizes said pressure signals to limit the blood flow within preset acceptable inlet and/or outlet pump pressure. A simple, compact and disposable system to adjust, regulate, and indicate negative or positive pressure applied to the valve is also disclosed. For compactness and clarity, the description is provided in the context of a roller pump for circuits used during cardiopulmonary bypass. The invention is also useful in other applications, such as dialysis, ultrafiltration, enteral feeding and organ preservation.

摘要： An endoscope overtube includes a flexible tubular member and a hub assembly provided at the proximal end of the tubular member. The hub assembly includes an elastic sleeve seal cuff extending about the inner surface of a body member of the hub. The ends of seal cuff are coupled to the body member. An inflation line extends into the body member in communication with the outer surface of the seal cuff. When fluid is pressurized through the inflation line, the cuff is distended inward to reduce the size of the opening through the port such that the cuff forms a seal about an endoscope received through the hub. The body member is preferably coupled to each of the flexible tubular member and to the elastic seal cuff using a snap-fit engagement of parts such that no fasteners, welds, glues, etc. are necessary for securing the hub assembly together.
