摘要： The disclosure herein discloses a levered set of barbs, tangs or jaws for engaging a shoulder of a port from a body fluid device. The port of the body fluid device can have a shoulder or a series of barbs and a shoulder. Interiorly of the connector is a resilient interior member. The interior member is sloped interiorly to match the end region of the port. It receives the end of the port in displaced relationship in a manner whereby the interior member provides a seat that deforms against the end of the port as well as deforming outwardly to provide an angularly sloped member and a resilient seat in combination with each other for an expanded seated seal.

摘要： This invention relates to the electrochemical machining of integrally formed prosthetic heart valve structures in which both the structural integrity of the valve and the blood flow through the valve is improved as a result of the integral formation of the valve structure. In particular, such heart valves comprise a ring and a pendant structure, such as a strut, for supporting the opening and closing of a discoid valve occluder. Integral formation of the strut with the ring permits the cross-sectional shape of the strut to be machined without overheating and distortion to conform to a teardrop shape having favorable fluid-dynamic characteristics thereby improving the flow of blood through the valve across the strut. The integral formation of the strut with the ring further results in the elimination of the weld fillet between the strut and the ring, thereby permitting the height of the ring to be reduced, which further improves the fluid dynamic characteristics of the valve. The overall structural integrity of the heart valve structure is also improved by the shape of the strut which permits the increase in the total cross-sectional area of the strut while retaining the favorable fluid flow characteristics of the valve. Thus, this invention provides for improved structural integrity of the valve and at the same time, improved flow characteristics through the valve.
摘要翻译：本发明涉及整体形成的假体心脏瓣膜结构的电化学加工，其中由于阀结构的整体形成，瓣膜的结构完整性和通过瓣膜的血液流动都得到改善。特别地，这种心脏瓣膜包括环和悬挂结构，例如支柱，用于支撑盘状瓣膜闭塞器的打开和关闭。支柱与环的整体形成允许加工支柱的横截面形状而不会过热和变形，以符合具有有利的流体动力特性的泪滴形状，从而改善穿过支柱的阀通过阀的流动。支柱与环的整体形成进一步导致消除支柱和环之间的焊缝，从而允许减小环的高度，这进一步改善了阀的流体动力特性。通过支柱的形状也可以改善心脏瓣膜结构的整体结构完整性，这样可以在保持阀的有利的流体流动特性的同时增加支柱的总横截面面积。因此，本发明提供了改进的阀的结构完整性，同时提高了通过阀的流动特性。

摘要： A volume sensing system includes electronic circuitry which is electrically connected to an ultrasonic transducer. The transducer is affixed by means of an adaptor to the base of a container having a known configuration. The container holds a liquid and a gas so that a liquid-gas boundary is formed within the container. The transducer generates ultrasonic pulses which propagate through the liquid, are reflected at the liquid-gas boundary, and are received again by the transducer. The received return pulse is converted into an electrical signal which is analyzed by the electronic circuitry to determine the level of the liquid within the container. The level of the liquid within the container is then employed to determine the volume of the liquid within the container in accordance with the configuration of the container. In a preferred embodiment, the adaptor includes an indicator which may be used to identify the configuration of the container.

摘要： A computer terminal keyboard is sealed by a molded elastomeric top cover, shaped to conform to the housing and keys of the keyboard, and a bottom cover shaped to enclose the base of and secure the top cover around its periphery to the keyboard housing. The top cover is shaped to provide a substantially planar surface on the top plate with elevated individual key covers integrally formed in the top cover. Portitons of the top cover extending over the top face and sides of the keyboard housing are formed in a first thickness sufficient to provide a durable covering. Portions of the top cover immediately adjacent and between the individual key covers, and the sides of the key covers, are formed in a reduced, second thickness to allow for flexure as the keys are depressed. The top surface of the top cover is planar so that spilled liquid and debris are easily wiped or brushed away from around and between the key covers. The bottom cover is formed of a rigid material and has edges shaped to mate snugly against wraparound flanges on the periphery of the top cover. The bottom cover secured by screws in existing screw holes in the underside of the keyboard housing.

摘要： The present invention discloses a reversible turbine-driven sprinkler head which includes a vaned turbine motor for rotatably driving a nozzle. The turbine is unresponsive to the norml flow of fluid through the sprinkler head to the nozzle. Switchable deflection means are included for deflecting the flow of fluid through the body against the turbine to cause rotation thereof in either of two directions. By deflecting the fluid flow to cause the turbine to rotate in one direction, the nozzle is rotated in one direction. By switching the direction of fluid deflection to cause the turbine to flow in the opposite direction, the nozzle is rotated in the opposite direction. Adjustable means are provided for setting the positions relative to the rotation of the nozzle whereat the deflection of the fluid flow is reversed, whereby the nozzle is caused to repeatably oscillate between a first and a second position.

摘要： Disclosed is a vacuum regulator apparatus such as for automatically establishing and maintaining a predetermined vacuum for withdrawing fluid from a chest cavity. The apparatus comprises a water manometer or vacuum regulator portion and a water seal portion. Atmospheric air is vented into the vacuum line through the vacuum regulator portion by displacing a predetermined height column of a fluid such as water. A filter is disclosed for preventing the escape of water from the manometer portion of the apparatus into the downstream vacuum source. A second filter is disclosed for permitting two way gas flow at the upstream end of the manometer portion, but for substantially preventing fluid flow in an upstream direction out of the manometer. Fluid fill ports are disclosed on the manometer and water seal portions for permitting infusion of water to precise and repeatable column heights.

摘要： The disclosure herein sets forth a pleural drainage/autotransfusion unit in combination with a cardiotomy reservoir having a vacuum regulating chamber in connected relationship to the pleural drainage/autotransfusion unit. The vacuum regulating chamber is formed of a portion of said cardiotomy reservoir unit and extends along the axial direction of the reservoir of the autotransfusion unit and can be connected to a source of vacuum. A water seal is interposed between the vacuum regulating chamber and the interior of the reservoir in order to provide for water sealed negative pressure within the reservoir. The function of the cardiotomy reservoir and the pleural drainage/autotransfusion unit can be changed by means of connections that have spring loaded tangs that engage a flange of a barbed inlet port. The connection is sealed by means of a resilient plastic material engaging the barbed inlet ports and can be readily removed therefrom and sealed without the requirement of sealing a tube which has been shrunken over the barbs of the inlet port.
