Vital capacity training equipment for respiratory medicine department

Abstract

The respiratory medicine vital capacity training equipment comprises a rectangular cabinet body, a vertical partition plate is arranged in the cabinet body and divides the cabinet body into a left measuring chamber and a right measuring chamber, the right measuring chamber comprises a built-in power generation motor, the power generation motor is provided with an autorotation gear, the autorotation gear makes contact with a transverse rack, and the transverse rack makes contact with the cabinet body. The rack is connected with a sliding variable resistance block, the sliding variable resistance block comprises a vertical current-conducting plate and a vertical stress plate, a closed current-conducting chamber is formed by the current-conducting plate and a cavity where the power generation motor is located, a constant cavity is defined between the current-conducting plate and the stress plate, and the side, away from the current-conducting chamber, of the stress plate is sequentially connected with an air inlet guide pipe and a blowing nozzle. According to the technical scheme, when the blowing force of a measurer is exhausted, the volume in the conductive chamber is reduced by the sliding variable resistance block, so that the pressure in the conductive chamber is increased, the sliding variable resistance block is returned, and air flows back to the blowing nozzle through the air inlet guide pipe in the returning process, so that saliva or sundries in the air inlet guide pipe are blown out, and the air inlet guide pipe is kept unblocked.

Description

technical field [0001] The invention belongs to the field of lung capacity training, and in particular relates to a lung capacity training device for respiratory medicine. Background technique [0002] Respiration is the process of gas exchange between the body and the external environment. The human respiration process includes three interrelated links: external respiration, including lung ventilation and lung ventilation; gas transportation in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. A normal adult breathes 6.4 seconds at a time when it is quiet, and the amount of gas inhaled and exhaled each time is about 500 ml, which is called tidal volume. According to the survey, the reduction of lung capacity makes people more likely to develop a variety of lung health diseases in old age, such as bronchitis, asthma and other diseases, and the lung capacity may also be reduced due to lung surgery or laryngeal surgery.

Problems solved by technology

[0003] However, the existing breathing equipment cannot clean the breathing return pipeline. After long-term use, the pipeline will accumulate excessive saliva and bacteria, causing measurement errors or cross-infection of respiratory diseases
