RIGID DISPOSABLE FLOW PATH

摘要

The present invention provides a disposable rigid flow path which by itself or in conjunction with a clam shell or manifold system provides additional pressure resistance for the disposable device. In a first embodiment, the device is comprised of a first sheet of rigid plastic material and a second sheet of plastic material. Each sheet has a first major surface and a second major surface and a thickness between the first and second major surfaces. At least one and preferably both have flow channels formed in them. The flow channels are formed in the sheet such that they extend away from the first major surface of the sheet and beyond the normal plane of the second major surface of the sheet.. The first and second sheets are liquid tightly sealed to each other at their adjoining first major surfaces.
