1. The product has passed CFDA and national standards. 2. 2. taking cardiac R wave as the trigger signal and QRS wave as the discriminating basis, synchronizing the filling and exhausting with the cardiac cycle. 3. 3. with oxygen saturation detection function, real-time display of finger pulse wave, counterpulsation wave and its ratio (D/S ratio) to reflect the therapeutic effect during treatment. 4. adopts liquid crystal computer display, and easy to operate. 5. cardiology, blood oxygen collection and system control integrated circuit, avoiding the data transmission problem of multiple boards and cards, and enhancing system reliability. 6. adopting special integrated block with gas solenoid valve for extracorporeal counterpulsation, the response time is ≤40ms. 7. adopting imported air compressor, reducing consumption and noise. 8. adopts advanced technology of negative pressure forced exhaust, which makes the exhaust rapid and thorough, and significantly reduces the afterload of the patient's heart. 9. The display interface shows real-time heart rate, oxygen saturation, filling and exhausting graphics, set pressure value, real-time treatment pressure value, current time, remaining time of treatment, etc. 10. counterpulsation ratio: 1:1 or 1:2; common mode rejection ratio ≥80dB; QRS wave detection threshold 0.20mV. 11. If the heart rate is irregular or less than 125 beats/minute, the normal counterpulsation can still be continued at a ratio of 1:1 in a three-stage sequence. 12. 12. The treatment time is adjustable from 1-60 minutes, and at the end of the treatment, the pump is automatically turned off and rapidly deflated. 13. Adjustable ECG and pulse wave gain. 14. 14. with automatic pressure stabilization function, the error between the treatment pressure and the set pressure is less than 0.002MPa. 15. 15. automatic stopping of counterpulsation when the heart rate exceeds the counterpulsation limit, and automatic resumption of counterpulsation when the heart rate is normal. 16. It will not inflate when there is no patient's ECG signal on the screen, so as to avoid chaotic pacing caused by simulated ECG in the machine. 17. can display counterpulsation and cardiac synchronization time. 18. the thigh capsule and the hip capsule are more comfortable than the one-piece capsule. 19. The database can record the patient's information. It has the ability to freeze the display image during treatment, and can print the waveforms and data shown on the display. 20. There are multiple safety protection measures to fully guarantee the safety treatment. 21. 21. The whole machine is a one-piece movable. 22. 22. According to the ergonomic design of the bed and capsule cover, bed backrest height 0-45º adjustable. 23. 23. Power supply: single-phase 220V, 2500W. 24. 24. Net weight: 325 kG, gross weight: 390 kG, volume (L×W×H): 210×88×106 CM.
