ABSTRACT
Procedure of a bioelectric signal collection system for vivo critter is introduced in this paper. It is easy to measure the bioimpedance in the tip of appliance, when puncture into the tissue, especially puncture into the bone tissue. We can get a judgment on the position of appliance, thereby achieve assistance on the clinic operation.

This paper introduces an impedance pneumograph monitor based on the single chip computer 80C552. It shares the same pair electrodes with ECG, and not only be applied to a multi-parameter physiological monitor as a subfunction model, but also can be operated as an independent instrument. This impedance pneumograph monitor can retrain the external interference such as ECG and myoelectricity with high efficiency, and has the advantages of smooth tespiratory waveform, good stability and high clinical application value.
