摘要： A needleless device for introducing or withdrawing a fluid to/from the vascular system of a being. The device includes first and second housing sections movably connected with respect to each other and which define a hollow interior in which a pair of resilient valve elements are located. The first housing section includes a first luer fitting for connection to an input line. The second housing section includes a second luer fitting for connection to an output line. A tubular plunger is located within the device and is arranged, when the housing sections are in a first position, to be automatically extended through a first valve element if the input line is connected to the first luer fitting, so that a liquid can be forced from the input line through the device to the output line. When the housing sections are in the first position and the input line disconnected from the first luer fitting, the tubular plunger is retracted out of both valve elements so that the device is fully occluded. The housing sections are movable to a second position with the input line connected to the first luer fitting, whereupon the tubular plunger is extended through both valve elements to provide free fluid communication between the input and output lines.

摘要： Apparatus for introducing a catheter percutaneously into the body of a living being. The apparatus comprises a tubular member having a distal end portion and a proximal end portion. The proximal end portion is in the form of a hollow housing for a hemostatic valve assembly comprising a lubricant reservoir and a valve element. The reservoir is formed of a foam material impregnated with a lubricant liquid, e.g., silicone. The valve element is a disk-like member formed of resilient material, e.g., silicone impregnated with polydimethylsiloxane, located distally of the reservoir and has a openable passageway extending through it for the catheter to pass. The reservoir applies the lubricating fluid-in a controlled manner onto the catheter as it is passed through it, to thereby facilitate the passage of the catheter through the openable passageway in the valve element. The hollow housing is arranged to produce peripheral pressure on the valve element to facilitate its closure.

摘要： A Y-connector including a hemostatic valve for enabling the introduction of an elongated member, e.g., a balloon catheter, into the body of a living being while precluding blood from flowing out of the valve. The Y-connector includes a housing having an interior in which a pair of resilient valve elements and a plunger mechanism are located. One valve element, e.g., a disk-like member, has a small diameter opening therein. The other valve element, e.g., a duck-bill valve elements, includes a normally closed, but openable, aperture therein. The plunger mechanism includes a tubular member having an outer diameter which is smaller than the diameter of the opening in the one valve element. The tubular member is arranged to be moved into and out of the opening in the one valve member and into and out of the aperture in the other valve element. The tubular member has a central passageway arranged to enable the elongated member to be readily extended therethrough for location at a desired position within the body of the being. The one valve element is arranged for engaging the periphery of the elongated member after the elongated member has been extended through the passageway and after the tubular member is moved out of the opening in the valve member to preclude blood from flowing through the interface between the valve member and the elongated member.
摘要翻译： 一种Y型连接器，其包括止血阀，用于能够将诸如气囊导管的细长构件引入活体的身体，同时防止血液从阀流出。 Y型连接器包括具有内部的壳体，其中定位有一对弹性阀元件和柱塞机构。 一个阀元件，例如圆盘状构件，其中具有小直径的开口。 另一个阀元件，例如鸭嘴阀元件，其中包括常闭，但可打开的孔。 柱塞机构包括具有比一个阀元件中的开口的直径小的外径的管状构件。 管状构件被布置成在一个阀构件中移入和移出开口中并进入和离开另一个阀元件中的孔。 管状构件具有中心通道，该中心通道被布置成使得细长构件能够容易地延伸穿过其中，以便位于所述体内的期望位置。 一个阀元件布置成在细长构件已经延伸通过通道之后并且在管状构件移出阀构件中的开口之后接合细长构件的周边以防止血液流过阀门 构件和细长构件。

摘要： A disposable sheath for use with clinical measurement probes, such as a temperature probe. Two sheaths are provided, each with an open end, and which are attached to each other near their respective distal ends. The first sheath covers the probe, and the second sheath covers the first as measurements are taken. After withdrawal of the probe, the second sheath may be inverted to avoid contamination of the environment and other patients. Further pulling of the disposable cover removes it from the probe, which may then be used again without cleaning or sterilization.
