Embodiment 1

[0018] A breathing detection abdominal belt, comprising a housing 2 and an abdominal belt 1, a Hall sensor array 3 is installed inside the housing 2, the abdominal belt 1 passes through the housing 2, one side of the abdominal belt 1 A permanent magnet 4 is installed. The permanent magnet 4 is located inside the casing 2 , and the magnetic poles of the permanent magnet 4 face the Hall sensor array 3 . By stretching the abdominal belt 1 , relative motion occurs between the permanent magnet 4 and the Hall sensor array 3 .

[0019] When in use, the breathing detection abdominal belt of this embodiment is fastened on the user's abdomen. The tightness of the abdominal belt 1 is adjusted so that the casing 2 can be attached to the abdomen of the user no matter whether the user exhales or inhales. When the user inhales, the abdominal cavity expands, which is equivalent to stretching the abdominal belt 1; when the user inhales, the abdominal cavity contracts, and the previously stre...

Embodiment 2

[0022] For the purpose of improving the sensitivity of the device, the unit elongation of the left and right ends of the permanent magnet 4 should be different when the abdominal belt 1 is stretched by the same external force.

[0023] The basic structure of this embodiment is the same as that of Embodiment 1, except that two implementation modes are provided for the above purpose.

[0024] One is: see Image 6 A section of the abdominal belt 1 located inside the housing 2 and between the fixed connection point 9 and the permanent magnet 4 has elasticity, and the rest of the abdominal belt 1 has no elasticity or less elasticity. In this case, when the user's abdomen rises and falls with breathing, the permanent magnet 4 will reciprocate right and left due to the resultant force. As shown in the figure, the fixed connection point 9 is on the left side of the permanent magnet 4, that is, a section of the abdominal belt 1 on the left side of the permanent magnet 4 is elastic, wh...

Abstract

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.

Description

technical field [0001] The invention relates to the field of respiratory frequency detection devices. Background technique [0002] Respiration is an important physiological process of the human body and an essential process of gas exchange between the internal and external environment of the human body. The human body inhales oxygen and exhales carbon dioxide through the respiratory system to maintain normal physiological functions. In modern monitoring technology, respiratory rate detection is an important part of it. The respiratory rate varies with age, gender and physiological state: the respiratory rate of adults is about 16-18 times per minute when they are calm; children are about 20 times per minute; Women 1-2 times faster than men. In clinical diagnosis, doctors can use respiratory frequency to preliminarily detect whether the human body is suffering from diseases. Since the respiratory signal is taken from the human body, the signal source impedance is high, and ...
