Abstract
Disclosed herein are a method and a retainer arrangement for applying a membrane to a physiological sensing unit for the transcutaneous determination of the magnitude of physiological quantities, particularly for measuring the partial pressure of gases in blood or the like. The invention proposes the preparation of a preassembly thus constituting a spare part which will be ready for application to the sensing unit when needed. The preassembly comprises a membrane, a clamping ring for removably assembling the membrane with the sensing unit, and means, including an auxiliary retainer element, for temporarily and removably securing the membrane to the clamping ring prior to assembly with the sensing unit.
Claims8
A retainer arrangement for applying a membrane to a physiological sensing unit for the transcutaneous determination of the magnitude of physiological quantities, particularly for measuring the partial pressure of gases in blood or the like, comprising a membrane, a clamping ring for removably assembling the membrane with the sensing unit, and means, including an auxiliary retainer element made of self-adhesive foam material, for temporarily and removably securing the membrane to the clamping ring prior to assembly with the sensing unit.
A method for applying a membrane to a physiological sensing unit for the transcutaneous determination of the magnitude of physiological quantities, particularly for measuring the partial pressure of gases in blood or the like, wherein the membrane is removably secured to the sensing unit in its working position by means of a clamping ring, comprising preassembling the membrane with the clamping ring by adhering an auxiliary retainer element in the form of a disc-shaped piece of self-adhesive foam material to the membrane and fitting the disc-shaped piece into a correspondingly shaped opening in the clamping ring, means of an auxiliary retainer element, applying the preassembly thus formed to the sensing unit with each, the clamping ring and the membrane, in its working position, and removing the auxiliary retainer element.
