[0004] In the above scheme, the bottom of the liquid food tube is connected to a lower cover, one side of the lower cover is connected to a fixed tube, a fixed plate is connected between the fixed tube and the lower cover, and an extrusion plate is provided inside the liquid food tube. The above scheme still has the following disadvantages: although this device can push the liquid food into the stomach to a certain extent, due to the close contact between the extrusion plate and the inner wall of the liquid food tube, after long-term use, it may become more difficult for the device to push the liquid food into the stomach. Utility Model Content

[0005] The purpose of the utility model is to provide a gastric tube perfusion device to solve the problem that due to the close contact between the extrusion plate and the inner wall of the liquid food tube, it may become difficult for the device to push the liquid food into the stomach after long-term use.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solution: a gastric tube infusion device, including an upper cover, which is arranged at the upper end of a needle tube, an external thread is provided on the outer wall of the upper end of the needle tube, an internal thread is provided on the inner wall of the upper cover, the internal thread is threadedly connected to the external thread, a first axial hole is provided on the upper cover, a long shaft is rotatably connected to the interior of the first axial hole, one end of the long shaft is fixedly connected to a mounting ring, a first rubber sleeve is connected to the upper outer wall of the mounting ring, and a second rubber sleeve is connected to the lower outer wall of the mounting ring.

[0007] Preferably, a second axial hole is opened on the lower end of the needle tube, and the interior of the second axial hole is connected to a liquid outlet tube.

[0008] Preferably, one side of the needle tube is connected with scale lines, and the scale lines are equidistantly distributed on the outer wall of the needle tube.

[0009] Preferably, rectangular blocks are connected to the left and right sides of the upper cover, and a pushing block is connected to one end of the long axis.

[0010] Preferably, two anti-slip rings are connected to the outer surface of the liquid outlet pipe, and the two anti-slip rings are fixedly sleeved on the liquid outlet pipe.

[0011] Preferably, a scraper is connected to the inner wall of the lower end of the needle tube, and the upper cover is detachable from the needle tube.

[0012] Compared with the prior art, a gastric tube perfusion device using the above technical solution has the following beneficial effects:

[0013] During use, the operator first moves the long shaft by dragging the push block. This movement of the long shaft drives the mounting ring, which in turn moves the first and second rubber sleeves, gradually approaching the upper cover. Next, the operator rotates the upper cover to introduce the prepared fluid into the syringe. The operator rotates the upper cover again to securely engage the syringe, ensuring a tight seal. The outlet tube at the lower end of the syringe is then connected to the catheter. As the fluid is introduced, the second rubber sleeve on the mounting ring pushes it into the catheter. Once the fluid is fully introduced, the operator rotates the push block. This rotation drives the long shaft, which in turn drives the mounting ring. This rotation of the mounting ring rotates the second rubber sleeve, which, with the help of a scraper, removes any residual fluid from the second rubber sleeve, preparing for the next operation. The operator then moves the push block again to move the long shaft. As the long shaft moves, the mounting ring also moves, gradually bringing the first and second rubber sleeves closer to the upper cover. At this time, the first rubber sleeve will clean the inner wall of the needle tube again, making it clean and reducing the amount of liquid food remaining on the inner wall of the needle tube. In this way, when the liquid food is pushed into the catheter, the process will be more labor-saving;

[0014] 2. During use, the scale lines on the syringe provide clear guidance for staff, allowing them to accurately understand the amount of liquid poured into the syringe and the remaining amount. Through these scale lines, staff can easily grasp the intake of liquid food, so as to better manage the diet. The design of the scale lines makes the feeding process more convenient and safe. For patients who need precise control of their diet, these scale lines can help them ensure the accuracy of each feeding amount and avoid discomfort caused by overfeeding or too little. In addition, these scale lines can also help staff better record and manage the amount of feeding each time, so as to better grasp the total intake;

[0015] 3. During use, the design of the anti-slip ring can increase the friction between the connecting pipe and the catheter, which not only effectively prevents the catheter from accidentally falling off from the device due to external force or long-term use, but also improves the safety and reliability of the overall structure.

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, a gastric tube infusion device includes an upper cover 1, which is mounted on the upper end of a needle tube 2. An external thread 3 is formed on the outer wall of the upper end of the needle tube 2, and an internal thread 4 is formed on the inner wall of the upper cover 1, which is threadedly connected to the external thread 3. The upper cover 1 has a first axial hole 5, within which a long shaft 6 is rotatably connected. One end of the long shaft 6 is fixedly connected to a mounting ring 7. A first rubber sleeve 8 is connected to the upper outer wall of the mounting ring 7, and a second rubber sleeve 9 is connected to the lower outer wall of the mounting ring 7. A second axial hole 10 is formed at the lower end of the needle tube 2, and a liquid outlet tube 11 is connected to the interior of the second axial hole 10. Rectangular blocks 13 are connected to the left and right sides of the upper cover 1, and a push block 14 is connected to one end of the long shaft 6. A scraper 16 is connected to the inner wall of the lower end of the needle tube 2. The upper cover 1 is detachable from the needle tube 2.

[0024] During use, the operator first needs to drag the push block 14, which will cause the long shaft 6 to move. This movement of the long shaft 6 will also drive the movement of the mounting ring 7. When the mounting ring 7 moves, the first rubber sleeve 8 and the second rubber sleeve 9 will also move with it, gradually approaching the position of the upper cover 1. Next, the operator needs to rotate the upper cover 1 and place the pre-prepared fluid into the syringe 2 through the upper cover 1. The upper cover 1 is rotated again to tightly fit the syringe 2 and ensure that the syringe 2 is sealed. Then, the liquid outlet tube 11 at the lower end of the syringe 2 is connected to the catheter. During the process of pushing the fluid, the second rubber sleeve 9 on the mounting ring 7 will push the fluid into the catheter. When the fluid is fully pushed in, the operator needs to rotate the push block 14. The rotation of the push block 14 will drive the long shaft 6, which in turn drives the rotation of the mounting ring 7. The rotation of the mounting ring 7 will cause the second rubber sleeve 9 to rotate. Under the action of the scraper 16, the residual fluid on the second rubber sleeve 9 is cleaned, preparing for the next operation. Next, the staff member once again moves the push block 14, driving the long shaft 6. As the long shaft 6 moves, the mounting ring 7 also moves, gradually bringing the first and second rubber sleeves 8 and 9 closer to the upper cover 1. At this point, the first rubber sleeve 8 once again cleans the inner wall of the needle tube 2, reducing any residual fluid on the inner wall. This makes the process of pushing the fluid into the catheter much more labor-efficient.

[0025] like Figure 1-Figure 5 As shown, one side of the needle tube 2 is connected with scale lines 12 , and the scale lines 12 are evenly distributed on the outer wall of the needle tube 2 .

[0026] During use, the graduated lines 12 on the syringe 2 provide clear guidance for staff, allowing them to accurately understand the amount of liquid poured into and the remaining amount in the syringe 2. These graduated lines 12 allow staff to easily monitor liquid food intake, thereby better managing the diet. The design of the graduated lines 12 makes the feeding process more convenient and safer. For patients who require precise dietary control, these graduated lines 12 can help them ensure the accuracy of each feeding amount, avoiding discomfort caused by overfeeding or underfeeding. Furthermore, these graduated lines 12 help staff better record and manage each feeding amount, thereby better understanding the total intake.

[0027] like Figure 1-Figure 5 As shown, two anti-slip rings 15 are connected to the outer surface of the liquid outlet pipe 11 , and the two anti-slip rings 15 are fixedly sleeved on the liquid outlet pipe 11 .

[0028] During use, the design of the anti-slip ring 15 can increase the friction between the connecting tube and the catheter, which not only effectively prevents the catheter from accidentally falling off the device due to external force or long-term use, but also improves the safety and reliability of the overall structure.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
