APPARATUS FOR ANALYSIS OF ABSORBED GASES

摘要

A device in the form of a flexible intravascular probe for use in analysing absorbed blood gases includes a gas-permeable membrane 10 comprising two layers in intimate contact and supporting each other. The permeability of the second layer6 is significantly less than that of the first 5, and provides the desired permeability of the membrane 10 as a whole. The first layer 5 provides the desired mechanical compatibility and other properties of the membrane 10.
