Lung capacity training device for respiratory medicine departments and method for operating lung capacity training device

Abstract

The invention discloses a lung capacity training device for respiratory medicine departments and a method for operating the lung capacity training device. The lung capacity training device comprises an inflator, an adjusting piston, a nut and a main piston. A first metal plate is fixedly connected with the inner wall of a left side plate of the inflator, a first air tube is fixedly connected withthe left side of the top of the inflator and is fixedly connected with a first blowing nozzle, an electric bell is further fixedly connected with the top of the inflator, a training cavity is formed by the adjusting piston and an inner cavity on the left side of the inflator, a fourth metal plate is fixedly connected with the left side of the adjusting piston, a threaded rod is fixedly connected with the right side of the adjusting piston, a second air pipe is further fixedly connected onto the adjusting piston and is fixedly connected with a second blowing nozzle, the main piston is slidablyconnected into the training cavity, and a second metal plate and a third metal plate are fixedly connected with the left center and the right center of the main piston. The lung capacity training device and the method have the advantages that the size of the training cavity can be adjusted by the aid of the nut, and accordingly the air blowing quantities can be set; air can be blown via the firstblowing nozzle and the second blowing nozzle, and accordingly the lung capacity can be trained; the electric bell can ring after the air reaches the set air blowing quantities, and accordingly trainees can be reminded that the air already reaches the set air blowing quantities.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lung capacity training device for respiratory medicine and a method for using the same. Background technique [0002] Respiration refers to 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 transport in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. It is best for a normal adult to breathe once at a time of 6.4 seconds, and the volume of gas inhaled and exhaled each time is about 500 milliliters, which is called tidal volume. [0003] According to the survey, the reduction of lung capacity makes people more prone to a variety of lung health diseases after old age, such as bronchitis, asthma and other diseases, and lung surgery or throat surgery may also cau...

Problems solved by technology

[0003] According to the survey, the reduction of lung capacity makes people more prone to a variety of lung health diseases after old age, such as bronchitis, asthma and other diseases, and lung surgery or throat surgery may also cause lung capacity reduction. The existing Medical equipment There is no medical equipment specifically for training the patient's lungs. Swimming can exercise the patient's lung capacity, but this method is limited by venue factors
