[0002] External counterpulsation (EECP) is a non-invasive treatment that uses an external device to improve cardiac blood flow. It is primarily used for patients with coronary artery disease, angina pectoris, and chronic heart failure. It works by applying pressure to the lower limbs and buttocks during diastole using a balloon, increasing blood return and cardiac blood flow, thereby improving myocardial ischemia and systemic circulation.
[0003] The existing external counterpulsation system's gas supply and transmission system is an independent setting. Due to the excessive bends in the pipeline, the resistance along the gas transmission is increased, and gas leakage occurs during the gas transmission process.

[0006] In order to solve the technical problem, the technical solution provided by the present invention is: an integrated extracorporeal counterpulsation gas storage tank solenoid valve, including a gas storage tank, the gas storage tank is provided with three DN15 internal thread interfaces, the three DN15 internal thread interfaces are provided with interconnected solenoid valves, the gas storage tank is provided with a DN15 short section pipe connected to the air compressor interface, the length is 50 mm, the air compressor works to store compressed gas in the gas storage tank, and a mounting seat is provided at the bottom of the gas storage tank.
[0007] Furthermore, the gas storage tank is provided with an air hole connected to the DN15 internal thread interface, and the DN15 internal thread interface is seamlessly welded to the outer wall of the gas storage tank and connected to the air hole.
[0008] Furthermore, the diameter of the air hole is 20 mm, and the specification size of the DN15 internal thread interface is DN15.
[0009] Furthermore, the height of the gas tank is 400-600mm, the length is 600MM, the gas tank 1 is installed horizontally, the tank diameter of the gas tank is 300-400mm, the height is 400mm, and the gas tank 1 is installed vertically.
[0010] Furthermore, the gas tank is installed horizontally, and the three DN15 internal thread interfaces are distributed in a straight line as a whole; the gas tank is installed vertically, and the three DN15 internal thread interfaces are distributed in a triangular shape as a whole.
[0011] Furthermore, the mounting base is provided with a mounting hole for mounting the gas storage tank in a suitable position by means of bolts.
[0012] The beneficial effects of the present invention are as follows: the present invention opens a hole on the gas tank and welds a DN15 internal thread pipe fitting, and directly installs the solenoid valve on the gas tank. On the basis of the original separation of the gas tank and the solenoid valve, the gas tank and the solenoid valve can be designed to be integrated, and the connecting pipe between the traditional solenoid valve and the gas tank is removed, thereby solving the problems of gas leakage caused by excessively long pipelines and increased resistance along the gas transmission process, and preventing gas leakage between gas transmission pipelines.

[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] According to the attached Figure 1-4As shown: The present invention provides an integrated extracorporeal counterpulsation gas storage tank solenoid valve, including a gas storage tank 1, three DN15 internal thread interfaces 2 are provided on the gas storage tank 1, and a connected solenoid valve 3 is provided on the DN15 internal thread interface 2. The gas storage tank 1 is provided with an air hole connected to the DN15 internal thread interface 2, and the air hole diameter is 20 mm. The specification size of the DN15 internal thread interface 2 is DN15, and the DN15 internal thread interface 2 is seamlessly welded to the outer wall of the gas storage tank 1 and connected to the air hole. Specifically, a hole is opened and welded on the gas storage tank 1 with a DN15 internal thread pipe fitting, and the solenoid valve 3 is directly installed on the gas storage tank, which are respectively an arm airbag charging and exhaust solenoid valve group, a thigh airbag charging and exhaust solenoid valve group, and a calf airbag charging and exhaust solenoid valve group, thereby being able to remove the connecting pipe between the traditional solenoid valve 3 and the gas storage tank 1, thereby solving the problems of gas leakage due to excessive length of the pipeline and increased resistance along the gas transmission process.
[0021] As an optional embodiment, the gas tank 1 is provided with a DN15 short section pipe 4 connected to the air compressor interface, with a length of 50mm. The air compressor works to store compressed gas in the gas tank 1. The height of the gas tank 1 is 400-600mm and the length is 600MM. The gas tank 1 is installed horizontally. The tank diameter of the gas tank 1 is 300-400mm and the height is 400mm. The gas tank 1 is installed vertically; the gas tank 1 is installed horizontally, and the three DN15 internal thread interfaces 2 are distributed in a straight line as a whole; the gas tank 1 is installed vertically, and the three DN15 internal thread interfaces 2 are distributed in a triangular shape as a whole; a gas tank 1 of appropriate size is selected so that the air compressor and the gas tank 1 mounting base 5 are assembled into one to save space.
[0022] The air compressor adopts the existing technology. The air compressor is abbreviated as air compressor. It is a device that converts mechanical energy into gas pressure energy. Its core function is to increase the pressure or transport the gas by compressing the gas. It is widely used in many fields such as industry, manufacturing, and scientific research. The air compressor works to store the compressed gas in the gas tank 1. The bottom of the gas tank 1 is provided with a mounting base 5, and the mounting base 5 is provided with a mounting hole for mounting the gas tank 1 on a suitable position or equipment by bolts.
[0023] Working principle:
[0024] The air compressor interface pipe 4 is connected to the output end of the air compressor to store the compressed gas in the gas tank 1. A hole is opened on the gas tank 1 and a DN15 internal thread pipe fitting is welded. The solenoid valve 3 is directly installed on the gas tank, which includes an arm airbag charging and exhaust solenoid valve group, a thigh airbag charging and exhaust solenoid valve group, and a calf airbag charging and exhaust solenoid valve group. Therefore, on the basis of the original separation of the gas tank and the solenoid valve, the gas tank 1 and the solenoid valve 3 can be designed to be integrated, and the connecting pipe between the traditional solenoid valve 3 and the gas tank 1 is removed, which solves the problems of gas leakage due to excessive length of the pipeline and increased resistance along the gas transmission process, eliminates gas leakage between the gas transmission pipelines, and facilitates the inspection, maintenance and replacement of the solenoid valve. Compared with the traditional method, the installation occupies less space and reduces gas loss.
