Abstract
A disposable assembly for use with a sensor assembly, and method for making the same, the disposable comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned along the fluid flow passage between the inlet and the outlet. The fluid pressure membrane is at a location in the fluid flow passage between the inlet and the outlet. The fluid pressure membrane defines an opening for receiving the flow restricting element. The fluid pressure membrane is located between the lid portion and the base portion of the body.
