ABSTRACT:
A container is provided that is disposable, for first collecting blood delivered from a patient, preferably by means of a vacuum draw of blood into a container, and then the blood in the container is treated. The treatment is provided by an at least partial a back-and-forth or reciprocating motion of blood along membranes, such that filtrate components of the blood pass through the membrane walls and are collected, whereby retentate components of the blood are retained, with the back-and-forth motion being provided by means of a substantially constant vacuum draw, that provides a pumping action by means of a diaphragm pump. A replenishment liquid is automatically added, substantially proportional to the amount of filtrate components of the blood that are withdrawn. The membranes are protected by a means for removing body fats or other potentially harmful materials. Various automatic techniques are also supplied to control the amount of replenishment liquid being added, and the amount of retentate components of the blood that are retained. Various safety features are also provided.
