Description

Technical Field

[0001] The utility model relates to the technical field of lung function rehabilitation training, in particular to a damping adjustable lung function training cylinder and a lung function training device. Background Art

[0002] Vital capacity refers to the amount of air that can be exhaled after maximum inhalation. It includes tidal volume, supplementary inspiratory volume and supplementary expiratory volume. Tidal volume refers to the amount of air inhaled or exhaled by the lungs in one breathing cycle. The maximum amount of air inhaled beyond the tidal volume is the supplementary inspiratory volume, the maximum amount of air exhaled beyond the tidal volume is the supplementary expiratory volume, and the amount of air remaining in the lungs after maximum exhalation is the residual volume. There are large individual differences. It is affected by factors such as age, gender, body shape, respiratory muscle strength, and lung and thorax elasticity. Vital capacity is closely related to human breathing. Physiological studies have shown that the organs, systems, tissues, and cells of the human body consume oxygen every moment, and the body can only work normally when there is sufficient oxygen supply. The oxygen supply inside the human body is obtained entirely by the breathing of the lungs. During the breathing process, the lungs not only take in oxygen, but also expel carbon dioxide metabolized in the body. We can think of it this way: the lungs are the transit station for the body's gas exchange. The volume of this transit station directly determines the amount of gas exchange during each breath. This is the most intuitive and objective indicator for testing lung function.

[0003] Chinese utility model patent CN209221447U discloses a respiratory medicine vital capacity training device, including a shell body, a blowpipe is fixedly connected to one side of the shell body, a mouthpiece is threadedly connected to one end of the blowpipe, a first through-tube is fixedly connected to the other end of the blowpipe, and a second through-tube is fixedly connected to one end of the first through-tube. When the first screw cap is opened, the patient blows up, and the first floating ball will rise accordingly, and the height of the first floating ball will change with the size of the blowing force. When the second screw cap is opened, the patient blows up, and the second floating ball will rise accordingly, and the height of the second floating ball will change with the size of the blowing force. Since the mass of the first floating ball is larger than that of the second floating ball, for different patients, the size of the patient's vital capacity can be observed through the first transparent tube and the second transparent tube.

[0004] However, the above-mentioned lung capacity training device has the following defects:

[0005] 1. Since vital capacity training adopts the principle of impedance training, and the exhalation impedance of the above training device is only determined by the mass of individual floats, considering that the vital capacity training intensity of different patients is different, it may be difficult to meet the training needs of some patients by simply increasing the blowing height of the float without changing the mass of the float. Therefore, the versatility of the above training device is poor;

[0006] 2. After frequent lung capacity impedance training, a large amount of saliva will remain inside the device. Since the above-mentioned lung capacity training device adopts an integral structure, it is difficult for medical staff to thoroughly disinfect the inside. In the long run, it will not only produce odor, but also easily breed bacteria, posing a risk of cross infection. Utility Model Content
