[0002] EECP is a method of non-invasively pressing the lower body externally to relieve and eliminate angina symptoms and improve the hypoxic-ischemic state of important organs. It is also a medical device used to prevent and treat cardiovascular and cerebrovascular diseases. It uses air bags wrapped around the limbs and buttocks to inflate and pressurize the air bags during the diastole of the heart, so that the blood in the limb arteries is driven back to the aorta, which significantly increases the diastolic pressure, increases blood flow to the heart, and reduces the afterload of the heart. During the systole of the heart, the air bags are quickly deflated, the pressure is released, and the systolic pressure in the aorta is reduced, which minimizes the resistance of the heart during the ejection phase and accelerates the blood flow to the distal end, thereby achieving the counterpulsation effect.

The exhaust speed and exhaust volume can be controlled by the setting of the air inlet solenoid valve 308. The exhaust pipe 307 discharges the gas used for counterpulsation when exhausting after counterpulsation. The connected silencer box 305 can effectively reduce the noise during exhaust, and improve the quietness and comfort during counterpulsation. At the same time, the gas passing through the silencer box 305 will return to the structural frame 2 through the compressor 301.

[0054] 2. About the heat dissipation of this solution:

[0055] 1. Regarding the heat dissipation of the compressor 301: When the compressor 301 is running, the cooling fan of the compressor 301 itself creates a pressure difference between the outside and the compressor 301, and the cooling air enters through the air holes of the grid connecting plate and the shell, and is guided to the compressor through the opening structure inside the shell, and then is discharged out of the device through the hot air outlet of the compressor 301 on the lower shell by the cooling fan 110, so as to cool the compressor 301.

[0056] 2. After the air is compressed by the compressor 301, the pressure increases, and the temperature of the gas also increases. The compressed gas enters the structural frame 2. The material of the structural frame 2 is preferably stainless steel, which can make the compressed gas inside exchange heat with the outside world. Because it is composed of multiple horizontal gas tanks and vertical gas tanks, compared with the method of separately set gas storage tanks, its surface area is larger and the heat dissipation effect is better. In addition, because the higher temperature part of the compressed air rises under the action of buoyancy, and the lower temperature part of the air falls, the heat dissipation fan 110 is set on the top of the second mounting plate 107. The hot air can be well discharged to the outside of the shell 1 through the exhaust holes on the shell 1. It is more in line with physical principles, making the heat dissipation effect better, and it is also more energy-saving and environmentally friendly. The structural frame also serves as a gas storage tank, which can also improve the heat dissipation effect, save space, and reduce the use of supporting structures while ensuring the supporting strength, and can also achieve lightweight.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims.
