The fluid enters the microbubble generating device after passing through the three-stage filtration and generates bubbles with a diameter ≤ 50 μm through the Venturi tube.

[0036] Reverse recovery path: wound area → negative pressure drainage tube → liquid storage tank; the negative pressure value is dynamically controlled in the range of -5 to -15 kPa through the PID algorithm to realize the recycling of the flushing liquid and reduce the risk of cross-infection.

The biological protection module innovatively adopts the pulsating spraying technology to form a chitosan protective film with a thickness uniformity of RSD ≤ 5% and an adhesion of 3.6 N / cm 2 so that the water loss from the wound is reduced by 58% and continuous antibacterial effect lasts for 72 hours. The electrolyzed water generation unit controls the residual chlorine concentration fluctuation within ±0.05 ppm through a pulse width modulation circuit. Cooperating with the platinum-iridium alloy electrode, the current efficiency reaches 85% and the electrode life is extended to 2000 hours. In terms of system coordination, the closed-loop circulation design and machine learning algorithm cooperate to reduce the energy consumption by 35%.
