Description

  The present invention relates to an infrared respiration detection processing device, and more particularly, an infrared respiration detection process that can collect respiration data of a living body from a region near the skull of a living body and can be used for medical diagnosis, and is suitable for use in an inquiry or the like. It relates to the device.

The respiration data of the living body is generated based on the output signal.

  In the case of such a means, although the respiration data of the living body can be obtained with certainty, a respiration sensor is arranged in the mouth or nose, and therefore there is a problem that stress is given particularly during sleep of the living body. .

Patent Document 1 proposes a respiratory data collection system configured to attach a respiratory sound sensor that collects respiratory data of the nose and mouth to the palate. Also in this patent document 1, since a respiratory sound sensor is attached to the palate, stress is also applied during sleep of the living body.
