Abstract: An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

Abstract translation: 独立的血液过滤装置取决于流动几何形状，以输送不含血红蛋白有害水平的血清或血浆。 它严重依赖于限制过滤元件上的压差变化率的上游流量或压差限制控制元件或装置。 可以使用预抽真空的方式同时从生活中吸取血液，并在抽真空的收集器和向大气开放的供应端之间跨过滤元件提供压力差。 通过手动加压的单元采用部分填充的采血管的外部形状作为活塞，以在控制元件或装置之前产生压力，以产生跨越过滤元件的压力差到通向大气的收集器。 控制元件或装置以多种形式公开，包括特别尺寸的流动收缩和顺应装置。
