The nasogastric feeding tube and feeding pump can be connected, and the feeding pump can be used to inject food into the nasogastric feeding tube for eating. Patients generally eat liquid food. If they want to drink water, they need to clean the liquid food in the feeding pump and inject water into the feeding pump for feeding, or remove the feeding pump for liquid food and replace it with a feeding pump for water. During the nasogastric feeding process, if there is air in the catheter that is not completely removed, the air entering the stomach will cause bloating, and the patient may feel uncomfortable. The accumulation of air in the stomach will increase the pressure in the stomach, causing the patient to have symptoms such as hiccups, bloating, and even reflux.

The front nasogastric box 2 can be used to place liquid food, and the rear nasogastric box 2 can be used to place water. A heating component 3 is provided on the side of the nasogastric boxes 2 that are away from each other. The heating component 3 consists of a heating tube and a protective cover. The heating tubes are respectively arranged on the side walls of the nasogastric boxes 2 that are away from each other, and the protective cover is fixedly connected to the side walls of the nasogastric boxes 2 that are away from each other. The protective cover is used to surround the heating tubes, and the heating tubes can be protected by the protective cover. The heating component 3 can be turned on so that the heating component 3 can heat the food in the nasogastric box 2 to prevent the food from cooling down during eating.

When the piston rod 5 moves in the direction close to the nasogastric tube 9, the piston rod 5 can push the liquid food inside the injection tube 4 toward the nasogastric tube 9. At this time, under the action of the first one-way valve 8, the liquid food inside the injection tube 4 will not flow to the outside through the first one-way valve 8, and under the action of the second one-way valve 81, the liquid food can only enter the nasogastric tube 9 in one direction, thereby flowing into the patient's body through the nasogastric tube 9. A baffle 52 is fixedly connected to the top of the piston rod 5 near the connecting position between the nasogastric box 2 and the piston rod 5. The baffle 52 is used to block the connecting port between the nasogastric box 2 and the piston rod 5.
