Abstract: A gas/liquid separator for a gas analyzer is described. The separator includes a separator chamber made up of two component chambers. The first of these component chambers is relatively shallow in depth and serves to connect an input port with a lower output port. The second of these two component chambers is less shallow in depth and serves to interconnect the lower output port with the upper output port. This second component chamber is bounded by two diverging surfaces which diverge in the direction of the upper output port. A barrier extends into the separator chamber to separate the input port from the upper output port and to prevent the flow of liquid directly from the input port to the output port.

Abstract: A method of assembling a sensor head and permeable membrane with encapsulated electrolyte. A disposable fixation ring is part of a similarly disposable fixation ring assembly, the latter of which serves as a fixture for automatically mounting the membrane on the sensor head body with the electrolyte encapsulated. The ring is then employed to fasten the head to a patient's skin while the remainder of the assembly is discarded, the ring also being disposable after use on a patient.

Abstract: A polarized sensor assembly for a polarographic oxygen sensor. The assembly comprises a sensor head and a shielded cable, with a power unit in the cable. The head electrodes remain polarized at all times, permitting transfer of the sensor assembly from one patient monitoring system amplifier to another without losing its polarization.
