[0018] See also Figures 1 to 3 The utility model provides a technical solution: a conveniently connected nasogastric syringe, comprising a main body 1, a fixing seat 2 arranged at the end of the main body 1, and a food storage cylinder 3 arranged at the end of the fixing seat 2. A sealing mechanism is arranged at the connection between the food storage cylinder 3 and the fixing seat 2. The sealing mechanism consists of a card slot 31, a silicone seat 32, and a limiting groove 33. The card slot 31 is opened at the end of the food storage cylinder 3, the limiting groove 33 is opened on the inner side of the fixing seat 2, and the silicone seat 32 is arranged on the inner sides of the card slot 31 and the limiting groove 33. Through the designed sealing mechanism, the original nasogastric syringe is improved in use because the food storage cylinder 3 is installed, and the food storage cylinder 3 and the fixing seat 2 are connected by a threaded connection. The installation is carried out. This connection method is easy to operate, but there is a problem of insufficient sealing. By setting a sealing mechanism at the connection between the food storage cylinder 3 and the fixed seat 2, the sealing of the connection between the two is increased, and the sealing of the nasogastric syringe when in use is increased. The silicone seat 32 is a hollow cylindrical structure, and the surface of the silicone seat 32 is in a fit state with the inner wall of the card slot 31 and the inner wall of the limit groove 33. A pushing component 4 is provided on the inner side of the food storage cylinder 3. The pushing component 4 consists of a rod body 41 and a piston 42. The rod body 41 is arranged on the inner side of the food storage cylinder 3, and the piston 42 is arranged inside the food storage cylinder 3. The end of the rod body 41 is fixed to the inner side of the piston 42, and a switch 6 is provided on the surface of the main body 1.

[0019] In this embodiment, preferably, a push grip 5 is provided on the side of the main body 1, and a support mechanism is provided on the inner side of the push grip 5, and the support mechanism is composed of a support rod A51, a support rod B52, a storage groove 53, a telescopic component 54, a fixing groove 55, and a connecting rod 56. The support mechanism is used to improve the problem that the push grip 5 is accidentally pressed during use of the original nasogastric feeding syringe, causing the food inside the food storage tube 3 to overflow and cause food waste. By setting up the support mechanism, when the push grip 5 is not needed, the support rods A51 and B52 of the support mechanism are unfolded to support the push grip 5 and the main body 1, thereby limiting the range of movement of the push grip 5. The storage groove 53 is arranged on the inner side of the pushing handle 5, the support rod A51 is arranged on one side of the inner part of the storage groove 53, the support rod B52 is arranged on the other side of the inner part of the storage groove 53, the telescopic component 54 is arranged at the connection between one end of the support rod A51 and one end of the support rod B52, the fixing groove 55 is arranged on the side of the main body 1, the connecting rod 56 runs through the inner side of the other end of the support rod A51, the two ends of the connecting rod 56 are fixed to the two sides of the inner wall of the storage groove 53, and the telescopic component 54 is composed of a groove 541, a spring 542, and a block 543. The telescopic component 54 is used to make the distance between the support rod A51 and the support rod B52 telescopic. During the telescopic process, the support rod B52 is pushed by an external force, so that the block 543 moves inside the groove 541, and the spring 542 is compressed to achieve the contraction of the distance between the support rod B52 and the support rod A51. The block 543 is fixed to the other end of the support rod A51, and the groove 541 is opened at the other end of the support rod B52.

During the installation of the food storage cylinder 3, the installation end of the food storage cylinder 3 is inserted into the inner side of the fixed seat 2, and the food storage cylinder 3 is rotated to make the food storage cylinder 3 and the fixed seat 2 threadedly connected. During the threaded connection between the two, the silicone seat 32 is inserted into the inner side of the card groove 31 to increase the sealing of the connection between the food storage cylinder 3 and the fixed seat 2. Then, the external nasogastric tube is connected to the output end of the food storage cylinder 3, and the end of the external nasogastric tube is inserted into the patient's oral cavity. Then, the bottom end of the main body 1 is held, and the pushing grip 5 is pressed. The food is pushed by the pushing component 4, so that the food is delivered to the patient's oral cavity through the external nasogastric tube.
