Disposable Blood Centrifuge Liner

Nondisposable centrifuge bowls presently in use must be cleaned and sterilized after every use. These bowls are expensive and easily damaged.

The disposable liner shown can be constructed of thin plastic and, with a permanent supporting structure, will provide a cavity geometry similar to present reusable centrifuge bowls.

The subject liner has three, or possibly two, pieces permanently sealed or assembled with twelve tubes also sealed in position, to provide ports for the blood and its component parts. There is a formed clear plastic top piece 3, an inside filler 5, and an outer shell piece 7. The filler and shell may be constructed from one molded piece. Appropriate tubes are provided, such as the "whole blood" input tube 9 shown.

The liner unit is presterilized and disposed of after one use.
