[0032] The following are specific implementation cases and appendices. Figure 1-2 The present invention will be further described below, but the present invention is not limited to these embodiments.
[0033] like Figure 1-2 As shown, this utility model discloses a pulmonary function breathing trainer, including: a base 1, a display tube 2, a connecting tube 3, a breathing tube 4, a volume regulating device, an indicator ball 6, an end tube 7, and a heating and humidifying device; the top of the base 1 is connected to an internal threaded connector; the bottom of the display tube 2 is connected to a threaded head; the connecting tube 3 is connected to the bottom of the threaded head; the breathing tube 4 is connected to the base 1, and the top of the breathing tube 4 is connected to a connecting tube; the volume regulating device is connected to one side of the base 1; the indicator ball 6 is located inside the display tube 2; the end tube 7 is connected to one side of the display tube 2; and the heating and humidifying device is connected to one side of the end tube 7.
[0034] In embodiments of this utility model, such as Figure 1-2 As shown, the air volume regulating device includes: a side bracket 9 and a bolt rod 10; the side bracket 9 is connected to one side of the base 1; one end of the bolt rod 10 is connected to a plug, the bolt rod 10 is screwed to the side bracket 9, and the plug slides inside the breathing tube 4.
[0035] In embodiments of this utility model, such as Figure 1-2 As shown, the heating and humidifying device includes: an exhalation pipe 11, an intermediate pipe 12, a heating box 13, and a humidifier 14; the exhalation pipe 11 is connected to one side of the end pipe 7; one-way valves are inserted into both ends of the intermediate pipe 12, and the one-way valve on one side is connected to the exhalation pipe 11; several heating plates are connected inside the heating box 13, and several heating wires are connected to the heating plates; one end of the heating box 13 is connected to the one-way valve on the other side of the intermediate pipe 12, and a side pipe is connected to the other side of the heating box 13; the humidifier 14 is connected to the bottom of the intermediate pipe 12.
[0036] In embodiments of this utility model, such as Figure 1-2 As shown, it also includes: a power supply 5; the power supply 5 is connected to the bottom of the humidifier 14 and is used to supply power to the heating wires on the heating plate inside the humidifier 14 and the heating box 13.
[0037] In embodiments of this utility model, such as Figure 1-2 As shown, it also includes: a flexible tube 8; the flexible tube 8 is inserted into one end of the breathing tube 4.
[0038] Implementation process: During exhalation, place the end air tube 7 on top and the base 1 on the bottom. The user bites one end of the hose 8 and begins to exhale. The gas passes through the connecting air tube 3 and the connecting pipe and enters the display tube 2, blowing up the indicator bulb 6. The exhaled gas then exits from the exhalation outlet tube 11. Due to the one-way valve, the gas will not enter the heating and humidifying device, preventing moisture generated from prolonged exhalation from affecting the lifespan of the internal components of the heating and humidifying device. During inhalation, invert the device and rotate the middle tube 12. Because it is a plug-in connection, and both ends of the middle tube 12 have a snap-fit structure, airtightness is guaranteed. The heating box 13 is designed to meet the needs of the user. At the same time, the other end of the intermediate tube 12 also has a one-way valve, which allows the heating box 13 to only enter dry air from the outside and prevents the backflow of humid gas, thus increasing its service life. The heating wire inside the heating box 13 works to increase the heat inside the heating box 13. Meanwhile, after the humidifier 14 humidifies the air below the intermediate tube 12, the humidity and temperature of the air drawn into the user are appropriately increased, which can make the user feel comfortable. When the patient needs to adjust the airflow resistance according to the training needs or physiological state (such as the disease recovery stage), the rotating bolt rod 10 can be used to enhance the personalized adaptability of the training and gradually improve lung function.
