Abstract

The invention relates to an instrument which can monitor, record and analyze frequency, strength, and a time ratio of expiration to inspiration of respiratory movement of a human body, and has a function of an MP3 player. An oronasal airflow respiratory sensor (1) and an abdomen-thorax respiratory sensor (2) are adopted to respectively monitor respiratory airflow of an oronasal portion of the human body and respiratory monition change of the abdomen-thorax portion, so that respiratory data of the human body are comprehensively collected. The respiratory data are digitalized through an analog-digital (A/D) converter (3), a central processor (4) is taken as a core, so that functions, such as analyzing, storing, displaying and transmission, of the respiratory data and a respiratory suspended alarming function are achieved. The function of the MP3 player is added to relieve tension mood of a monitored person to a certain extent by playing of music, and objectivity of respiratory monitoring is improved. Wireless technology and internet technology are adopted to broaden use range of the respiratory monitor, and a patient can conduct self monitoring at home, and can be conveniently and rapidly contacted with a hospital and an emergency center.

Description

technical field [0001] The invention relates to a breathing monitor, which belongs to the technical field of medical monitoring. Background technique [0002] With the development of science and technology and the progress of society, the use of monitoring instruments for human respiratory movement is also increasing. At present, most of the instruments with respiratory monitoring function are medical devices similar to sleep monitors, which are more complicated to use and costly. Simple and rough, it is difficult to distinguish the intensity of breathing and the ratio of exhalation to inhalation, but these are the respiratory parameters that respiratory doctors are very concerned about. At the same time, respiratory doctors hope that patients can obtain the patient's respiratory movement data in a relaxed environment, so as to record the patient's respiratory movement more objectively. We are in urgent need of a respiratory monitor that is accurate in measurement, easy to...
