| Abstract: | For the function of vacuum functioning intermittently and perfusing intermittently and combination of them, the device of vacuum suction and perfusion is designed in wound recovery, which is controlled by STC 12C5A60S2 microcomputer. Vacuum pump and peristaltic pump are used in generating vacuum and perfusing respectively drived by DC motor. The suction pressure is controlled with PID method, and the adjustment of the perfusing flow is using look-up table method, the suction pressure is measured with pressure sensor of MPS20N0100D-D and amplification circuit of AD620, which is supplied power by three terminal voltage regulator module of TCL431, and the lcd 12864 is used to show work status. |
