Title:
DRIVE SYSTEM FOR MEDICAL VACUUM NEGATIVE-PRESSURE MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/105697
Kind Code:
A1
Abstract:
A drive system for a medical vacuum negative-pressure machine, comprising: an input power supply (1), an MCU controller (9), a power amplifier circuit (5), a negative-pressure pump assembly (6), and an air pressure acquisition circuit (7). The input power supply (1) is electrically connected to the MCU controller (9), and is used to supply power to the drive system for the medical vacuum negative-pressure machine. The power amplifier circuit (5) receives a control signal from the MCU controller (9), and controls the negative-pressure pump assembly (6) to start, close, or stop. The negative-pressure pump assembly (6) receives a signal sent by the power amplifier circuit (5) and used to control the negative-pressure pump assembly to start, close, or stop. The air pressure acquisition circuit (7) is provided on a gas inlet of the negative-pressure pump assembly (6), and is used to acquire changes in air pressure in an negative-pressure environment, convert same into voltage changes, and transmit data of the voltage changes to the MCU controller (9). The drive system simplifies the overall device layout, and facilitates use of the whole machine.
