Insertion type electrode arrangement for continuous pO.sub.2 measurement in living skin tissue
First Claim
1. A system for continuous pO2 measurements in living, restlessly moving tissue, comprising an outer spiral metal tube electrode having a longitudinal wall, a spiral tubular plastic body arranged in the outer metal tube and an electrically insulated platinum wire electrode arranged in the spiral plastic body, and a cylindrical plastics body, wherein both metal electrodes (2, 14) are fit with one terminal end (6) in the cylindrical plastics body (26), the electrodes having a free end extending from the plastics body and having a ground-off front end face, the front end face and the longitudinal wall including an angle of about 20°
- , an insertion assistance means for inserting the electrodes into the tissue, the cylindrical plastics body being fastened in the insertion assistance means, the electrodes extending from the cylindrical plastics body, the system further comprising a pO2 measuring apparatus, the platinum wire electrode being connected to the pO2 measuring apparatus, and a second measuring apparatus, the metal tube electrode being connected to the second measuring apparatus, the two measuring apparatus having reference electrodes (54) independent of each other.

Abstract
It is possible by means of a new spiral electrode arrangement to measure the pO2 partial pressure of restless moving tissue, for example on a child during labor. At the same time the electrode arrangement allows measurement of the child'"'"'s heartbeat frequency pattern during labor. By graphically representing both measurement patterns a doctor can determine when he must, for example, accelerate the birth or initiate other clinical measures.
