The flushing bag 2 is provided with a flushing liquid, which can be physiological saline. The flushing bag 2 is movably connected to the flushing tube 3, and the flushing tube 3 can use an infusion set, and the flushing tube 3 can also use a blood transfusion set. The end of the flushing tube 3 away from the flushing bag 2 is connected to the first interface of the three-way switch 4 through interference fit. 3 can also be fixedly connected to the first interface of the three-way switch 4 by a binding method, the second interface of the three-way switch 4 is connected to the gastric tube 5 by an interference fit method, the gastric tube 5 is far away from the end of the three-way switch 4 by the medical staff through the nasal cavity of the child to the stomach, the third interface of the three-way switch 4 is connected to the liquid storage tank 6 through the connecting pipe, the third interface of the three-way switch 4 can be connected to the connecting pipe by an interference fit method, the connecting pipe can also be fixedly connected to the three-way switch 4 by a binding method, the connecting pipe can be connected to the liquid storage tank 6 by an interference fit method, the connecting pipe can also be fixedly connected to the liquid storage tank 6 by a binding method, the liquid storage tank 6 is a glass tank, the liquid storage tank 6 is a transparent tank, the transparent tank is convenient for observing the liquid amount in the liquid storage tank 6, and can be replaced in time The liquid storage tank 6 has a scale value on its surface (the scale value is not drawn in the figure), and the scale value is set along the height direction of the liquid storage tank 6. The scale value is convenient for recording the amount of liquid in the liquid storage tank 6, and is convenient for comparing the amount of liquid in and out of the gastric lavage. When the first interface and the second interface of the three-way switch 4 are connected, the third interface is closed, and the flushing liquid in the flushing bag 2 enters the child's stomach through the flushing tube 3 and the gastric tube 5. The liquid storage tank 6 is connected to the negative pressure machine 7 through the connecting tube. The negative pressure machine 7 can use an existing strong hair dryer. The strong hair dryer is connected to an external switch and a power supply through electric wires. The negative pressure machine 7 can also use an existing negative pressure device. The negative pressure machine 7 forms a negative pressure in the liquid storage tank 6. When the second interface of the three-way switch 4 and When the third interface is connected, the first interface is closed, and the negative pressure machine 7 forms a negative pressure in the liquid storage tank 6. The flushing liquid and gastric contents in the child's stomach enter the liquid storage tank 6 through the gastric tube 5. The gastric tube 5 is conveniently exchanged between the flushing tube 3 and the liquid storage tank 6 through the three-way switch 4, which solves the problem that the traditional gastric lavage for children is mostly manual gastric lavage, which requires the gastric tube 5 to be repeatedly disassembled and assembled between the irrigation tube and the suction tube, resulting in a cumbersome operation process. The flushing bag 2 is movably connected to the pressurizing component 8, and the pressurizing component 8 can be a syringe. The syringe can be connected to the air inlet pipe of the infusion set through interference fit, and the syringe injects air into the flushing bag 2 through the air inlet pipe to increase the pressure in the flushing bag 2;The pressurizing component 8 can also be pressurized by an air bag. Air is injected into the flushing bag 2 through the compression and relaxation of the air bag to increase the pressure in the flushing bag 2. The increased pressure in the flushing bag 2 increases the flow rate of the flushing liquid in the flushing bag 2 and reduces the flushing liquid infusion time, thereby solving the problem pointed out in the background technology that the flushing liquid pressure decreases as the amount of liquid decreases, thereby extending the flushing liquid infusion time. In addition, the above structure is simple and easy to use. When in use, first, the medical staff inserts the gastric tube 5 through the child's nasal cavity into the stomach. At the same time, another medical staff hangs the flushing bag 2 on the support frame 1 and connects one end of the flushing tube 3 to the flushing bag 2. , then, connect the end of the flushing tube 3 away from the flushing bag 2 to the first interface of the three-way switch 4, then connect the third interface of the three-way switch 4 to the liquid storage tank 6 through the connecting pipe, then connect the liquid storage tank 6 to the negative pressure machine 7, and connect the negative pressure machine 7 to the power supply through the switch, then connect the second interface of the three-way switch 4 to the gastric tube 5, then connect the pressurizing component 8 to the flushing bag 2, and finally, perform gastric lavage on the child by adjusting the three-way switch 4, the pressurizing component 8 and the negative pressure machine 7; therefore, the advantage of this embodiment is that the above-mentioned setting is adopted to facilitate the exchange of the gastric tube 5 between the flushing tube 3 and the liquid storage tank 6, and reduce the time of flushing liquid infusion. ;
[0027] like Figure 1 As shown, the flushing tube 3 is a plastic tube, which is a medical plastic tube. The flushing tube 3 is connected to a regulating valve 9, which can be a flow valve of an infusion set or other existing plastic valves. The regulating valve 9 is used to adjust the flow rate of the flushing liquid in the flushing tube 3.

The tip of the hollow puncture needle 801 can be inserted into the flushing bag 2. The one-way valve (the one-way valve is not shown in the figure) can be connected to the tail of the hollow puncture needle 801 by a threaded manner. The one-way valve is close to the hollow puncture needle 801. The one-way valve can prevent the flushing liquid in the flushing bag 2 from entering the pipeline 802. The tail of the hollow puncture needle 801 is connected to one end of the pipeline 802 by an interference fit. The one-way valve is located in the pipeline 802. The other end of the pipeline 802 is connected to the pressurizing ball 803 by an interference fit. The pressurizing ball 803 can be a balloon of a sphygmomanometer.
