Automatic gastric lavage device under intelligent control

Abstract

The invention discloses an automatic gastric lavage device under intelligent control. The device comprises a gastric lavage device body and a control system, the gastric lavage device body comprises a micro pump, the micro pump is provided with a positive pressure opening and a negative pressure opening, the positive pressure opening and the negative pressure opening are connected with a third electromagnetic valve through a first electromagnetic valve and a second electromagnetic valve respectively, the third electromagnetic valve is connected with a pressure sensor, the pressure sensor is connected with a waste water vat and a liquid medicine vat, a fourth electromagnetic valve is arranged between the pressure sensor and the liquid medicine vat, gas-liquid separation plates are arranged in the waste water vat and the liquid medicine vat respectively, each gas-liquid separation plate is provided with a travel switch, the waste water vat is connected with a waste water bucket through a first pneumatic valve, and the liquid medicine vat is connected with a liquid medicine bucket through a second pneumatic valve. The automatic gastric lavage device is low in cost, parameters are easy to adjust and set, control precision can be improved conveniently through a compensating circuit, the electrical control part is relatively independent, system universality is great, and the functions of gastric lavage, independent attraction, digital display, backflushing, alarm giving and the like are achieved.

Description

technical field [0001] The invention relates to the field of emergency medical equipment, in particular to an intelligently controlled automatic gastric lavage device. Background technique [0002] Gastric lavage machine is the most commonly used medical equipment in hospitals to rescue food poisoning patients. It is widely used in rescuing poisoned patients, food poisoning patients and gastric lavage before surgery. It uses electromagnetic pump as the power source and controls the automatic control circuit to make the electromagnetic valve Change action, first inject flushing liquid into the stomach, and then suck out the gastric lavage process from the stomach. Gastric lavage with an automatic gastric lavage machine can quickly and thoroughly remove poison in the stomach. [0003] At present, the gastric lavage machines used in domestic hospitals are basically designed and produced based on the working principle of suction-type negative pressure self-priming. In the pipe...

AI Technical Summary

Problems solved by technology

[0004] From the operation and use of the gastric lavage machine, it can be seen that this type of gastric lavage machine is non-intelligent, with a low degree of automation and not completely reliable.

The insertion position of the gastric tube depends entirely on the experience of the operator; the operator should always observe the readings of the positive pressure gauge and the negative pressure gauge; Gastric valve; there is no clear instruction on the extent to which gastric lavage is performed and whether it is completed. This kind of gastric lavage machine has a low degree of automation and reliability, and accidents are prone to occur
