Abstract
A measuring sensor head for determining the contents of gases in liquids, particularly for transcutaneous determination of oxygen in blood, as well as a method of manufacturing such sensor head are disclosed. In accordance with the invention, the gas-permeable membrane which covers the front face of the sensor head and which, during use, is applied to the human skin, is preshaped to assume a cap-shaped configuration. This eliminates previously occurring measuring errors due to uncontrollable stresses causing thickness variations generated in conventional membranes and, moreover, provides for an improved sealing effect between the housing of the measuring head and the membrane.
