Specifically, the present invention is because stomach will be sucked out in paunch flusher under the premise of not damaging stomach wall, during conventional gastric lavage
Liquid of gastric lavage is also injected, therefore monitored object is liquid measure and pressure in stomach.Lead to gastric lavage due to having no silicone tube clinic
The report of journey failure, it is believed that pipeline itself is the high reliability element that can not monitor.It should be inserted into when to avoid first aid gastric lavage
Stomach tube is inserted into liquid measure and hydrostatic sensor again, extends rescue time and increases operation difficulty, sensor is placed in machine by the machine
In interior gas circuit, using circuit supervision gas circuit operating condition, the method for carrying out gastric lavage with air pressure driving fluid path.
Working principle: the 4th solenoid valve is opened in gastric lavage, so that the first pneumatic operated valve and the second pneumatic operated valve is linked, is gone out in negative pressure
During stomach, when detecting that liquid medicine tank is connected to by pneumatic operated valve with liquid medicine barrel, when sewage cylinder is connected to stomach, stomach can be sucked
Sewage cylinder, liquid of gastric lavage are drawn to liquid medicine tank simultaneously, when travel switch movement after, two cylinder can be just filled, and stomach terminates out, be switched into
Stomach.During being just pressed into stomach, when detecting that pneumatic operated valve is connected to liquid medicine tank with stomach, when sewage cylinder is connected to slop pail
Liquid of gastric lavage is injected in stomach, while sewage cylinder is discharged to slop pail, when two cylinder empties, travel switch movement terminates into stomach, completes
Gastric lavage circulation.Above-mentioned stomach and the process into stomach out are repeated, until stomach cleaning is finished.In gastric lavage positive and negative pressure value by
Pressure sensor measurement.
P87LPC767 single-chip microcontroller is Philips company, small in size, and arithmetic speed is 2 times of standard 80C51, instruction with
51 series are compatible, there is the OTP program storage of 4KB, the RAM of 128B, 3 groups of ports I/O, the A/D converter containing 8,4 tunnel, support 4

It is configured to internal RC oscillator, frequency of oscillation 6MHz；It is resetted in piece, mouth line is high level after reset.
Pressure sensor of the present invention uses the silicon piezoresistive transducer ICSensor1220A-015G-3S of MEAS company.The biography
Four arm electrical bridge is used inside sensor, and there is temperature-compensating in 0~50 DEG C, maximum supply current 2mA, measurement range P≤
105kPa, zero-pressure output≤2mV.
Control system of the present invention is realized by the following method: since gastric juice pH is 3 or so, when pH is shown less than 5
It can be determined that Lavage tube has reached in stomach, illustrate Lavage tube not in stomach if pH value is greater than 6, cannot start to wash, it can
It is dangerous that tracheae booting gastric lavage bring is mistakenly inserted to avoid Lavage tube；Double-cavity gastric lavage tube can be while washing by the dirt after washing
Object discharge, the mouth of stomach tube uses elliptical shape in order to avoid dirt blocks nozzle out, if the outlet of stomach tube is blocked by dirt, PC machine can
Solenoid valve is controlled according to flow velocity and pressure change, is generated positive/negative pressure so that constant flow pump be rotated, in a certain range may be used
Independently to be set by doctor according to different patient profiles, be more than setting value will sound-light alarm, and automatically cut off the power；In device
Pressure sensor convert electric signal for actual pressure value, amplification, correction and temperature of the electric signal through oversampling circuit are mended
It will be sent to PC machine after repaying, compared with setting value, then by the revolving speed that PC machine adjusts control constant flow pump be allowed to generate user desired
Pressure value.
Based on above-mentioned, the present invention is at low cost, and parameter is easy adjusting, more easily can improve control by compensation circuit
Precision, and electric control system is relatively independent, and system is versatile, clinical requirement, and the operation is stable works well, while right
