[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 and Figure 2 A multifunctional rehabilitation training device for COPD care comprises a longitudinal support rod 2 with a support base 1 installed at the bottom, a component fixing plate 3 fixedly installed on the top of the longitudinal support rod 2, and a No. 1 component mounting port 4 and a No. 2 component mounting port 5 symmetrically arranged in the component fixing plate 3.

When the patient exhales, the gas will generate an upward gas pressure on the bottom of the conical valve plate 68. When the gas pressure is greater than the above-mentioned damping strength, the conical valve plate 68 will move upward, and the exhaled gas will move upward along the gap around the conical valve plate 68, and finally be discharged outwardly through the No. 1 exhaust channel 67, thereby realizing the ability to adjust the flow resistance of the exhaled gas.

[0025] For the specific structure of the elastic buffer type flow control mechanism 6, please refer to Figure 3 and Figure 4, comprising a first cylindrical hollow shell 61 fixedly mounted inside the first component mounting port 4, wherein the first cylindrical hollow shell 61 is provided with a cylindrical component movable cavity 62, wherein the bottom end of the cylindrical component movable cavity 62 is provided with a conical ventilation cavity 63, wherein the bottom end of the conical ventilation cavity 63 is provided with a first gas flow hole 64, wherein the first cylindrical hollow shell 61 is provided with a first air inlet passage 65 connected to the outside space at the bottom end of the first gas flow hole 64, wherein the first cylindrical hollow shell 61 is provided with a first gas inlet passage 65 connected to the outside space ...

[0026] In order to achieve a one-way inhalation function for oxygen and prevent the exhaled gas from flowing back into the oxygen storage area, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up a gas one-way flow control mechanism 7, which is provided with a No. 2 cylindrical hollow shell 71 fixedly installed in the No. 2 component installation port 5 and having a hollow interior, and a ball valve 75 placed inside the No. 2 cylindrical hollow shell 71 and capable of controlling the one-way flow of gas by its own gravity. When the patient inhales, the conical valve plate 68 will be in a closed state under the action of the coil spring 69, and when the inhalation pressure is greater than the gravity of the ball valve 75, the ball valve 75 will move, and oxygen will enter the patient's mouth and nose along the spherical cavity 72. When the patient exhales, the ball valve 75 will block the port of the No. 2 air inlet channel 74 under its own gravity, thereby realizing the one-way inhalation function of oxygen, thereby preventing the exhaled gas from flowing back to the oxygen storage area.

[0027] For the specific structure of the gas one-way flow control mechanism 7, please refer to Figure 5 and Figure 6 , including a No. 2 cylindrical hollow shell 71 fixedly installed in the No. 2 component installation port 5, a spherical cavity 72 is arranged at the center of the No. 2 cylindrical hollow shell 71, a No. 2 exhaust channel 73 connecting its upper surface and the top of the spherical cavity 72 is arranged inside the No. 2 cylindrical hollow shell 71, a No. 2 air intake channel 74 connecting its lower surface and the bottom of the spherical cavity 72 is arranged inside the No. 2 cylindrical hollow shell 71, a ball valve 75 is placed inside the No. 2 cylindrical hollow shell 71 located in the spherical cavity 72, the structural radius of the spherical cavity 72 is larger than the structural radius of the ball valve 75, and the structural radius of the ball valve 75 is larger than the structural radius of the No. 2 exhaust channel 73 and the No. 2 air intake channel 74.

[0028] When in use, the No. 1 air inlet channel 65 is connected to the pipe for exhalation from the patient's mouth, the No. 2 air inlet channel 74 is connected to the exhaust port of the oxygen storage tank, and the No. 2 exhaust channel 73 is connected to the pipe for the patient to inhale, and then the support base 1 is placed on the ground of the working area. When the patient inhales, the conical valve plate 68 will be in a closed state under the action of the coil spring 69, and when the inhalation pressure is greater than the gravity of the ball valve 75, the ball valve 75 will move, and oxygen will enter the patient's mouth and nose along the spherical cavity 72. When the patient exhales, the ball valve 75 will be blocked at the port of the No. 2 air inlet channel 74 under its own gravity, and the gas will generate an upward gas pressure on the bottom of the conical valve plate 68. When the gas pressure is greater than the above-mentioned damping strength, the conical valve plate 68 will move upward, and the exhaled gas will move upward along the gap around the conical valve plate 68, and finally be discharged outward through the No. 1 exhaust channel 67.
