On the basis of the above structure, the front outer walls of the waste liquid tank 4 and the liquid storage tank 5 are both inlaid with a transparent observation plate 6, which is made of organic glass. The upper right top of the liquid storage tank 5 is inlaid with a water inlet pipe 7;

The transparent observation panels 6 provided on the front outer walls of the waste liquid tank 4 and the liquid storage tank 5 facilitate observation of the liquid content inside the waste liquid tank 4 and facilitate timely processing and addition.

On the basis of the above structure, the cover assembly 8 includes a top cover 81, a rubber ring 82, a connecting hose 83 and a suction pipe 84. The rubber ring 82 is bonded to the bottom end surface of the top cover 81, the connecting hose 83 is fixedly penetrated inside the left end of the top cover 81, and the suction pipe 84 is fixedly penetrated inside the right end of the top cover 81. The other end of the suction pipe 84 is fixedly connected to the input end of the vacuum pump 10.

By starting the vacuum pump 10, negative pressure is generated inside the waste liquid tank 4 through the suction pipe 84, thereby facilitating the suction of the waste liquid.

On the basis of the above structure, the top cover 81 is in contact and sealed with the top of the waste liquid tank 4, and the interface between the top cover 81 and the waste liquid tank 4 is inclined;

The inclined structure of the interface between the top cover 81 and the waste liquid tank 4 facilitates full extrusion and fit with the rubber ring 82, so that the waste liquid tank 4 and the top cover 81 are in a completely sealed state, which facilitates negative pressure liquid suction.

On the basis of the above structure, the flushing hose assembly 9 includes a soft sleeve 91, a recovery chamber 92, a flushing chamber 93, a recessed hole 94, a rubber ball 95 and a bolt 96. The recovery chamber 92 and the flushing chamber 93 are provided inside the soft sleeve 91. A plurality of recessed holes 94 are provided at equal distances along the length direction on the upper and lower symmetrical outer walls of the soft sleeve 91. A rubber ball 95 is provided on the outer side of the soft sleeve 91 for sliding. The inner side of the rubber ball 95 is symmetrically threaded with a bolt 96.

By opening the recovery cavity 92 and the flushing cavity 93 inside the soft sleeve 91, the separate infusion hose and extraction hose in the comparative document can be replaced. During the washing process, it is not only easier to extract the waste liquid for circulating gastric lavage, but also can alleviate the pain of children and prevent children from feeling uncomfortable and having strong resistance. It is more suitable for pediatric gastric lavage and has a good effect.

On the basis of the above structure, one end of the connecting hose 83 away from the top cover 81 is fixedly connected to the drainage port of the recovery chamber 92 of the soft sleeve 91, and one end of the water delivery hose 12 away from the water pump 11 is fixedly connected to the water inlet of the flushing chamber 93 of the soft sleeve 91. The soft sleeve 91 is made of rubber.

The water supply hose 12 can be used to supply liquid to the flushing cavity 93 to facilitate gastric lavage, and the water pump 11 and the vacuum pump 10 can be turned on alternately. After the gastric lavage liquid flushes the stomach, the vacuum pump 10 is turned on to extract the waste liquid to facilitate sufficient flushing of the stomach.

The working principle of the utility model is as follows:

When in use, firstly, the gastric lavage liquid is filled into the liquid storage tank 5 through the water inlet pipe 7, and then the rubber ball 95 can be pushed to slide and adjust on the outside of the soft sleeve 91. The distance between the rubber ball 95 and the tube end of the soft sleeve 91 can be adjusted according to the body shape of the child. Then, the bolt 96 can be tightened to insert one end of the bolt 96 into the concave hole 94, so that the rubber ball 95 can be positioned on the outside of the soft sleeve 91. Then, the soft sleeve 91 is inserted into the patient's mouth and reaches the stomach. At this time, the rubber ball 95 is just stuck in the child's mouth. The rubber ball 95 can firstly prevent the child from struggling and causing the pipeline to slide back and fall off, and secondly, it can prevent the child from biting the pipeline and causing the pipeline to be blocked, so as to ensure the stable progress of gastric lavage.

The rubber soft sleeve 91 is provided with a recovery chamber 92 and a flushing chamber 93, which can replace the separate infusion hose and extraction hose in the reference document. In the process of washing, it is not only more convenient to extract the waste liquid for circulating gastric lavage, but also does not need to repeatedly plug and unplug the replacement pipe. It can also relieve the pain of children and prevent children from feeling uncomfortable and having strong resistance. It is more suitable for pediatric gastric lavage and has a good effect.

After the preparation work is completed, the water pump 11 can be turned on, the gastric lavage liquid in the liquid storage tank 5 can be extracted through the water suction pipe 13, and transported to the flushing cavity 93 inside the soft sleeve 91 through the water delivery hose 12, and gastric lavage can be started. Then the water pump 11 can be turned off, and the vacuum pump 10 can be turned on to generate negative pressure inside the waste liquid tank 4 through the suction pipe 84, and the waste liquid can be extracted and collected in the waste liquid tank 4 through the connecting hose 83 and the internal recovery cavity 92 of the soft sleeve 91. Gastric lavage is performed repeatedly in sequence, and gastric lavage is more sufficient, and there is no need to repeatedly plug and unplug and replace the pipeline, which not only relieves the patient's pain, but also reduces the workload of medical staff, and gastric lavage is faster. Finally, the electric telescopic rod 3 can be started to control the support platform 2 to drive the waste liquid tank 4 to move downward, so that the waste liquid inside the waste liquid tank 4 can be harmlessly treated, and when the waste liquid tank 4 and the top cover 81 are docked and conflicted, the connection between the two can be sealed by the rubber ring 82 to ensure the stability of negative pressure suction.
