[0064] like Figure 5 , Figure 6, Figure 7 as well as Figure 8 As shown, the first fixing mechanism 14 is arranged on the outer side wall of the shell 1, and the first fixing mechanism 14 includes two clamping plates 141. The two clamping plates 141 slide toward or away from each other on the side wall of the shell 1 in the vertical direction. The gastric tube 4 is located between the two clamping plates 141, and the inner walls of the two clamping plates 141 can abut against the side wall of the gastric tube 4; the first fixing mechanism 14 also includes a third driving component 142 for driving the clamping plate 141 to move and a second resetting component 143 for resetting the clamping plate 141. A limiting component 144 for limiting the clamping plate 141 is also provided on the side wall of the shell 1.

[0065] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the second reset assembly 143 includes a reset spring three 1431 and a guide rod two 1432. A fixed block three 1433 is fixedly arranged on the outer wall of the shell 1.

[0066] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, before the gastric tube 4 passes through the perforation 1 6, the two clamping plates 141 are located away from the gastric tube 4. Then, when the cutting mechanism 13 starts to work, the piston rod on the cylinder 1 131 can trigger the third driving assembly 142 when moving, and the third driving assembly 142 can push the clamping plate 141 to move in the direction close to the gastric tube 4, and the reset spring 3 1431 is stretched until the clamping plate 141 is pressed against the side wall of the gastric tube 4. At this time, the gastric tube 4 is fixed under the clamping action of the two clamping plates 141, so that the end of the gastric tube 4 can be easily plugged into the plug-in tube 16, and the clamping plate can be limited by the action of the limiting assembly 144; when the medical staff needs to remove the gastric tube 4, the limiting action of the limiting assembly 144 on the clamping plate 141 can be released first, and then the pulling force of the reset spring 3 1431 can pull the clamping plate 141 to move in the direction away from the gastric tube 4, so that the medical staff can easily remove the gastric tube 4.

[0067] like Figure 5 as well as Figure 6As shown, the third driving assembly 142 includes two connecting rods 1421, and the two connecting rods 1421 are arranged in a one-to-one correspondence with the two cylinders 131 and the two clamping plates 141. A push block 1422 is slidably arranged between the connecting rod 1421 and the clamping plate 141.

The two ends of the connecting rod 1421 are respectively hinged to the piston rod on the cylinder 131 and the push block 1422, and the push block 1422 can abut and cooperate with the clamping plate 141.

[0068] like Figure 5 as well as Figure 6 As shown, the piston rod on the cylinder 131 can drive the connecting rod 1421 to rotate while moving, and the rotation of the connecting rod 1421 can drive the push block 1422 to move. When the push block 1422 moves toward the direction close to the clamping plate 141, the push block 1422 can abut against the clamping plate 141 and push the clamping plate 141 to move toward the direction close to the gastric tube 4, thereby reducing the difficulty of moving the clamping plate 141; when the cutting mechanism 13 is finished working, the cylinder 131 can drive the push block 1422 to move to the initial position.

[0069] like Figure 7 as well as Figure 8 As shown, the limit assembly 144 includes a limit block 1441, a stop block 1442 and a push spring 1443. The limit block 1441 slides on the side wall of the shell 1, and the stop block 1442 is fixedly arranged on the side wall of the clamping plate 141. One end of the limit block 1441 is provided with an inclined surface, and the limit block 1441 can be slidably matched with the stop block 1442 through the inclined surface, and the stop block 1442 can abut against the side of the limit block 1441 away from its inclined surface; the two ends of the push spring 1443 are respectively fixedly arranged on the limit block 1441 and the side wall of the shell 1.

[0070] like Figure 7 as well as Figure 8 As shown, when the clamping plate 141 moves toward the direction approaching the gastric tube 4, the clamping plate 141 can drive the stopper 1442 to move, and the stopper 1442 can push the limit block 1441 to move through the inclined surface on the limit block 1441, and the pushing spring 1443 is compressed. When the inner wall of the clamping plate 141 abuts against the gastric tube 4, the elastic force of the pushing spring 1443 can push the limit block 1441 to move until the side of the limit block 1441 away from its inclined surface abuts against the stopper 1442. At this time, the stopper 1442 is limited, thereby reducing the possibility of the clamping plate 141 moving in the direction away from the gastric tube 4.

[0071] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, a second fixing mechanism 19 is also provided on the outer wall of the shell 1, and the second fixing mechanism 19 includes a ring 191, which is sleeved on the gastric tube 4, and the side wall of the ring 191 is fixedly provided with two connecting plates 192, and elastic bands 193 are fixedly provided on the two connecting plates 192, one end of one elastic band 193 is fixedly provided with a Velcro hook surface 194, and one end of the other elastic band 193 is fixedly provided with a Velcro fur surface 195, and the Velcro hook surface 194 can be bonded with the Velcro fur surface 195; a positioning component 197 for positioning the ring 191 is provided on the outer wall of the shell 1; the second fixing mechanism 19 also includes a fourth driving component 198 for driving the limit block 1441 to move.

[0072] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the positioning assembly 196 includes two magnet one 1961 and two magnet two 1962. The two magnet one 1961 are respectively installed on the two connecting plates 192, and the two magnet two 1962 are both installed on the side wall of the shell 1. The two magnet two 1962 can be magnetically attracted to the two magnet one 1961.

[0073] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the fourth driving assembly 198 includes an abutment block 1981 and an abutment block 1982. The abutment block 1981 is fixedly disposed on the connecting plate 192, and the abutment block 1982 is fixedly disposed on the limiting block 1441. A slope is provided on the side of the abutment block 1981 close to the abutment block 1982, and the abutment block 1981 can be slidably matched with the abutment block 1982 through the slope.

[0074] After the medical staff inserts the gastric tube 4 into the patient's nasal cavity or oral cavity, the ring 191 can be moved toward the patient. When the ring 191 is moved to a position close to the patient, the two elastic bands 193 are pulled to bind the gastric tube 4 to the patient or the bed, and the Velcro hook surface 194 is adhered to the Velcro fur surface 195, so that the gastric tube 4 can be fixed, reducing the impact of the gastric tube 4 shaking on the patient; when the medical staff needs to remove the gastric tube 4, they can first move it toward the direction close to the shell 1. Move the ring 191, and then the two magnets 1961 can be respectively attracted to the two magnets 1962, and the ring 191 is positioned on the shell 1, thereby reducing the possibility of losing the ring 191, and at the same time, the abutment block 1981 can gradually push the abutment block 1982 and the limit block 1441 to a position away from the stop block 1442 through the inclined surface, so as to facilitate the release of the limiting effect of the limit block 1441 on the clamping plate 2 141, and then facilitate the clamping plate 2 141 to move in the direction away from the gastric tube 4.

[0075] The implementation principle of the embodiment of the present application is as follows: the medical staff first winds the gastric tube 4 around the roller 3, and then clamps and fixes the beginning of the gastric tube 4 through the clamping mechanism 12; when the medical staff needs to perform gastrointestinal decompression on the patient, the clamping mechanism 12 is first driven to move toward the direction close to the through hole 16 on the side wall of the shell 1, and the clamping mechanism 12 can simultaneously drive the gastric tube 4 to move and pass the beginning of the gastric tube 4 through the through hole 16, so that it is convenient for the medical staff to pull the gastric tube 4, and the medical staff can pull the gastric tube 4 to a suitable length.

[0076] Then, the air pump 5 is turned on, and the medical staff can check whether the gastric tube 4 is inserted in place according to whether there is a sound of bubbles in the patient's abdominal cavity; thereafter, the gastric tube 4 is cut by the cutting mechanism 13. While the gastric tube 4 is being cut, the first fixing mechanism 14 can be triggered to fix the end of the cut gastric tube 4. After the gastric tube 4 is cut, the control component can be triggered to drive the driving plate 7 to move away from the perforation 6. At this time, the clamping mechanism 12 can move the starting end of the gastric tube 4 wound on the roller 3 away from the perforation 6 on the side wall and move it to the initial position. During the movement, the driving plate 7 can trigger the first driving component 17 to drive the slide to move in the direction close to the cut gastric tube 4. It can drive the plug-in tube 16 to move. When the driving plate 7 stops moving, the end of the gastric tube 4 cut off corresponds to the inner cavity of the plug-in tube 16, and then the pushing cylinder 18 is turned on to drive the plug-in tube 16 to move in the direction close to the gastric tube 4 until the end of the gastric tube 4 is plugged into the plug-in tube 16, and then the negative pressure pump is turned on to perform gastrointestinal decompression on the patient; when the treatment is over, the medical staff can remove the gastric tube 4 from the patient's oral or nasal cavity, and then release the fixing effect of the first fixing mechanism 14 on the gastric tube 4, so that the used gastric tube 4 can be removed, so as to facilitate the repeated use of the device; the whole process can facilitate the medical staff to replace the new gastric tube 4, thereby reducing the workload of the medical staff.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
