摘要： A dual chamber pumping apparatus (10) and method for infusing fluids to a patient includes a disk (12) having a fluid inlet (14) and a fluid outlet (16). Resilient membranes (22, 24) are attached to opposite sides of the disk (12) to establish dual pumping chambers (30, 32), and a network of one-way valves (34, 36) connects the fluid inlet (14) in alternating fluid communication with the pumping chambers (30, 32). A one-way outlet valve (16) connects the pumping chambers (30, 32) alternately in fluid communication with the fluid outlet (16). The one-way valves utilize a hollow, elastomeric tube (44) fixedly disposed in passageways within the disk (12) for covering and uncovering respective ports in response to fluid pressure differentials on the inner and outer surfaces of the walls of the hollow, elastomeric tube (44).
摘要翻译：用于向患者输注流体的双室抽吸装置（10）和方法包括具有流体入口（14）和流体出口（16）的盘（12）。弹性膜（22,24）附接到盘（12）的相对侧，以建立双泵腔（30,32），并且单向阀（34,36）的网络将流体入口（14）与泵送室（30,32）交替流体连通。单向出口阀（16）将泵送室（30,32）交替地与流体出口（16）流体连通地连接。单向阀利用固定地设置在盘（12）内的通道中的中空的弹性管（44），用于响应于中空弹性体的壁的内表面和外表面上的流体压力差而覆盖和露出相应的端口管（44）。

摘要： A disposable infusing device for ambulatory patients comprises a disk-shaped cover plate (18) and a disk-shaped impeller plate (32) which are interconnected by a stretched membrane (38) that joins the edge of the cover plate with the edge of the impeller plate. The effect of the membrane is to urge the plates into juxtaposition. A fluid port is formed on the cover plate for fluid communication through the port (2) with a collapsible fluid chamber (36) established between the plates. Fluid when injected into the chamber between the plates, is subsequently expelled through the port for controlled infusion to a patient as the membrane pulls the plates toward each other to collapse the chamber.

摘要： A cassette (20) for use with an I.V. infusion pump (42) has a housing (30) with a first inlet (24), a second inlet (28), an outlet (36), and a port (64) to the I.V. infusion pump. A valve body (60) is positioned within the housing to selectively establish fluid communication from the first inlet to the port, or from the second inlet to the port, or from the port to the outlet. Movement of the valve body within the housing into yet another position allows for the free flow of fluid directly between the first inlet or the second inlet and the outlet.
摘要翻译：一种与I.V.一起使用的盒（20）输液泵（42）具有壳体（30），其具有第一入口（24），第二入口（28），出口（36）和与所述第一入口（24）的端口（64）。输液泵。阀体（60）定位在壳体内以选择性地建立从第一入口到端口或从第二入口到端口或从端口到出口的流体连通。阀体在壳体内移动到另一位置允许流体在第一入口或第二入口和出口之间直接自由流动。
