Description

Technical Field

[0001] The present invention relates to the technical field of external counterpulsation high-pressure gas supply, in particular to an external counterpulsation high-pressure gas supply system. Background Art

[0002] Existing EECP airbags are generally placed in an airbag bag, which is then tied to the lower limbs of the human body. This device has a relatively simple structure. During use, the airbag must first be fixed in the airbag bag to ensure that it does not shift during inflation and deflation. At the same time, cloth or other backing materials are required on the contact surface between the airbag and the human body to prevent scratches on the human body caused by the shape change of the airbag during inflation and deflation.

[0003] Currently, most EVCP airbag supply devices on the market for medical rehabilitation use a balanced air supply scheme. This requires a relatively large air tank and a large tracheal diameter to quickly inflate the airbag to the set pressure. This increases the size of the device and reduces its portability. This ultimately increases device costs and reduces user experience, necessitating improvements. Summary of the Invention
