摘要： An umbilical cord cutting and clamping device includes first and second clamps held in a side-by-side abutting relation. Each clamp includes first and second arms hingeably connected at a first end, and gripping surfaces arranged on the interior of the arms. A blade is attached to the first arm of the first clamp and project into a space between the arms thereof. A pair of side splash guards are attached to abutting first arms on either side of the blade. A pair of front splash guards are attached to the second ends of the second arms and extend toward the first arms. When the clamps are closed around an umbilical cord, the cord is simultaneously clamped by the gripping surfaces and severed by the blade. The splash guards prevent blood from splashing onto surrounding persons when the umbilical cord is severed. The clamps are separable after clamping onto and severing the umbilical cord, so that the baby and the placenta can be separated.

摘要： An improved segmented peristaltic cartridge comprising a housing and a cover for assembly in snap-fit relation, said housing and cover defining a pumping chamber having an open segment therein wherein the pumping chamber holds a rotor, a rotor sleeve and a section of flexible tubing looped around the rotor and connected to respective inlet and outlet ports of the cartridge. Mounted on an exterior face of the housing is a safety shield which protects the tubing exposed in the open segment of the cartridge when the cartridge is inserted into a motor pump frame. The cartridge includes free standing walls on the cartridge housing engaging registration surfaces on the cartridge cover, an improved dowel pin structure and peripheral ribs on the rear cover and engaging a rear face of the rotor to minimize friction therebetween.

摘要： An umbilical cord cutting and clamping device includes two clamps abutted in a side-by-side relation and a blade connected to an arm of one of the clamps and positioned between the two clamps. Both clamps have an upper arm and a lower arm, and a hinge coupling the proximal ends of the upper and lower arms. The clamps are held in relative position by frictional engagement and by a latch means which is automatically disengaged when the clamps are moved into a closed position. Both the upper and lower arms include clamping surfaces for clamping the umbilical cord. The proximal end of one of the clamping surfaces is provide with a retention tab which retains the umbilical cord between the clamping surfaces; i.e., the tab prevents the cord from migrating proximally off the clamping surfaces and into the hinge area. The distal portions of the lower arms of the clamps include substantially vertical portions having ratchet surfaces having a plurality of proximally directed teeth which are engaged by a ratchet engagement means at the distal ends of the upper arms. The blade includes a cutting edge which is preferably angled distally downward relative to the upper arms. As the clamps are closed around a section of umbilical cord and clamp the cord, the blade extends between the clamping surfaces and cuts the cord, and the latch means is disengaged. The two clamps are separated from their friction fit while clamping the severed ends of the cord.
摘要翻译：脐带切割和夹紧装置包括以并排关系邻接的两个夹具和连接到一个夹具的臂的刀片并且位于两个夹具之间。两个夹具具有上臂和下臂，以及联接上臂和下臂的近端的铰链。夹具通过摩擦接合保持在相对位置，并通过闩锁装置保持，当夹具移动到关闭位置时，闩锁装置自动脱开。上臂和下臂都包括夹紧脐带的夹紧表面。一个夹紧表面的近端提供有将脐带保持在夹紧表面之间的保持突片; 即，突片防止绳索向近侧迁移离开夹紧表面并进入铰链区域。夹具的下臂的远端部分包括具有棘轮表面的大致垂直部分，棘轮表面具有多个向近侧指向的齿，其在上臂的远端处由棘轮接合装置接合。叶片包括切割边缘，该切割边缘优选地相对于上臂向远端向下倾斜。当夹具围绕脐带的一部分闭合并夹住绳索时，刀片在夹紧表面之间延伸并切割绳索，并且闩锁装置脱离。两个夹具与其摩擦配合分离，同时夹紧电源线的断开端。
