Gas pressure value reduce in gradient, by the collaborative work of above continuous multiple feedback control loops, gas can be reached in system
Inside successively, unidirectionally, constant flow.
8. constant temperature pneumoperitoneum system according to claim 1, it is characterised in that the controller (6) includes microcontroller and hardware electricity
Road, one-chip machine port are connected with hardware circuit, and hardware circuit will be conveyed to microcontroller, monolithic after the transmission signal processing of sensor
Command signal is conveyed first, second, third, fourth controlled valve and double storehouse heaters (16) by machine.
