thirdly, flow detection: the gastric lavage liquid passes through the flow sensor, the flow sensor outputs pulse signals to the signal collector, the signal collector starts a counting mode of the timer to directly obtain pulse result numbers, meanwhile, the signal collector starts another timer for timing treatment to obtain the pulse value in the corresponding time, thereby calculating corresponding accumulated flow and instantaneous flow, when the accumulated flow reaches a certain value during the absorption of gastric lavage fluid, the signal collector sends a signal to the controller, the controller controls the reversing valve to reverse, thereby communicating the first containing bottle with the first silicone tube, sucking the gastric lavage fluid in the first containing bottle into the first silicone tube by the pipeline, and enters a waste liquid bottle of the gastric lavage machine through a flow sensor, a pressure sensor and a second silicone tube, thereby avoiding that part of gastric lavage fluid sucked from the stomach remains in the circulating pipeline of the gastric lavage machine when the next time of filling the stomach with liquid;

fourthly, temperature detection: the temperature sensor detects the temperature of the gastric lavage fluid passing through the detection device and transmits a temperature signal to the signal collector, the signal collector compares the signal with a set value, and when the temperature of the gastric lavage fluid is lower than the set value, the signal collector controls the electric heating rod to work through the controller to rapidly heat the input gastric lavage fluid, so that the temperature of the gastric lavage fluid meets the requirement;

fifthly, data calculation and analysis: and (4) processing the signals transmitted in the second step, the third step and the fourth step by a signal collector, displaying the processed signals on a display by a controller, and displaying the forward and reverse values of the pressure on the display to judge that the gastric lavage machine is in a liquid flushing state or a liquid absorbing state.
