The invention aims at providing a device capable of detecting respiratory rate or amplitude according to thoracic and abdominal periodical changes during respiration, namely a respiration detection bellyband which comprises a casing and a bellyband body with elasticity. A Hall sensor array is installed in the casing. The bellyband body penetrates through the casing and is connected with the casing elastically. A permanent magnet is installed on one side of the bellyband body and located in the casing, and a magnetic pole faces the Hall sensor array. Output of the sensor depends on moving position of the permanent magnet and displacement length when the permanent magnet moves to the position, interference of peripheral environment is prevented effectively, and respiratory rate can be measured accurately. Simultaneously, the respiration detection bellyband is small and exquisite in structure, light in weight, convenient to carry and small in power consumption. The Hall displacement sensor is good in linearity, high in accuracy and strong in anti-interference capability. A buckle-type bellyband can also be used, circumference of the bellyband can be adjusted conveniently, and the bellyband is suitable for persons of all ages.

The invention relates to a sensor for measuring thorax-abdomen respiratory movement wave shapes and belongs to the technical field of medical monitoring. The sensor is manufactured by means of the amorphous wire giant stress impedance effect. The sensor is tied to a part of the thorax-abdomen to be measured by a specially equipped thorax-abdomen belt. Due to the respiratory movement, the circumference of the thorax-abdomen is changed, the change of the circumference conducts acting force to a sensor probe through the thorax-abdomen belt, and the respiratory movement wave shapes of a human body are obtained by signal extraction, signal amplification and signal filtering. The sensor for the thorax-abdomen respiratory movement wave shapes has the advantages of being high in sensitivity, small in size, strong in anti-interference performance, low in power consumption and the like. The defects that currently, a breath sensor is large in size and not high in sensitivity are solved. The novel breath sensor is widely applied to respiratory monitoring, sleep respiratory disturbance monitoring, critical patient monitoring and clinic in medicine and home health care.
