Abstract
A transcutaneous blood gas sensor has a sensor housing with a central projection, a ring-shaped collar to be attached to the skin and a membrane holder having a membrane stretcher hole. The central projection of the sensor housing fits into the stretcher hole for holding and retaining a membrane in position across the membrane stretcher hole whereby a ring zone of the membrane is clamped between the membrane holder and the ring-shaped collar. The central projection of the sensor body has a spherical end surface, whose radius of spherical curvature is at least twice and not more than six times the inner diameter of the membrane stretcher hole. The spherical end surface contacts a central membrane portion.
