The invention relates to the technical field of intelligent control of medical equipment, in particular to an external counterpulsation self-adaptive regulation and control system and method based on a generative adversarial network and digital twinning. The system acquires data through the acquisition module; the multi-modal signal processing module preprocesses the collected signals, and key hemodynamic features are extracted through multi-modal feature fusion; the digital twinborn modeling module constructs a specific blood vessel digital twinborn model, takes key hemodynamic characteristics, multi-modal physiological signals and patient static parameters as core input, and outputs hemodynamic simulation data in real time; the self-adaptive regulation and control module outputs counterpulsation pressure and a time sequence scheme on the basis of hemodynamics simulation data; an execution verification module drives an air bag to sequentially pressurize, a counterpulsation enhancement index is monitored in real time, parameter re-optimization is triggered through curative effect deviation, and meanwhile model re-training is carried out; according to the invention, the defects of weak signal anti-interference capability, lack of individual dynamic adaptation, disjunction of long-term curative effect prediction and the like of traditional external counterpulsation control are overcome.

This utility model discloses a vertical booster pump, which includes a drive cylinder and a booster cylinder arranged vertically. The drive cylinder includes a drive cylinder barrel, within which a drive cylinder piston is embedded. The booster cylinder includes a booster cylinder barrel, with a lower cover between the booster cylinder barrel and the drive cylinder barrel. The booster cylinder piston is embedded within the booster cylinder barrel, and the booster cylinder piston is fixedly connected to the drive cylinder piston via a piston rod that penetrates the lower cover of the drive cylinder. The lower cover of the drive cylinder has inlet and outlet ports on both sides, communicating with the interior of the booster cylinder barrel. A three-way connector is installed at the bottom of the booster cylinder barrel, communicating with the interior of the booster cylinder barrel. The two ends of the three-way connector are respectively connected to the main inlet pipe and the main outlet pipe. The main inlet pipe is connected to the inlet port via a feed bypass, and the main outlet pipe is connected to the outlet port via a discharge bypass. This vertical booster pump has a reasonable structural design, and its ingenious design allows for pressurization in any direction of drive cylinder movement, resulting in high boosting efficiency and promising application prospects.
