And the end of the gastric tube also needs to be carefully fixed with a safety pin on the edge of the pillow towel or the inner side of the collar and other places that are not easily affected, to maintain its stability. However, there is a certain distance between the fixing sticker and the end of the gastric tube. The gastric tube on this section of the path is prone to entanglement due to the patient's activities, affecting the treatment effect. Content of the Utility Model

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Please refer to Figures 1 to 5 , an anti-twisting device for a gastric tube catheter, including a gastric tube 1 and a mounting plate 2. By installing the part between the nasal body fixing part and the tail end of the gastric tube 1 on the mounting plate 2, winding can be avoided and normal use can be ensured.

[0029] A pipe-passing column 3 and a pipe-winding column 4 are fixedly installed at one end of the mounting plate 2. The pipe-passing column 3 allows the gastric tube 1 to pass through; a groove adapted to the gastric tube 1 is provided on the edge of the pipe-winding column 4, which can prevent the pipe body from falling off and shifting;

[0030] A slider 10 is slidably installed at the other end of the mounting plate 2. A pipe-passing column 3 and a pipe-winding column 4 are respectively fixedly installed on the slider 10, and the pipe-passing column 3 and the pipe-winding column 4 on the slider 10 are connected by a connecting block 11;

[0031] By pushing the connecting block 11 with a finger, the pipe-passing column 3 and the pipe-winding column 4 on the slider 10 can be moved. Furthermore, the distance between the pipe-passing column 3 and the pipe-winding column 4 on the slider 10 and the pipe-passing column 3 and the pipe-winding column 4 fixed on the mounting plate 2 changes, so that the length of the pipe body that can be laid on the mounting plate 2 changes, and the redundant part of the gastric tube 1 can be smoothly drawn out, so that the end of the gastric tube 1 is smoothly exposed and reaches the corresponding length for extraction or injection activities.

[0032] The mounting plate 2 is provided with a sliding groove 6 for the slider 10 to slide.

[0033] Both of the two pipe-passing columns 3 are provided with perforations 9 for the gastric tube 1 to pass through.

[0034] Both of the two pipe-passing columns 3 are provided with a limiting mechanism 5. The existence of the limiting mechanism 5 can exert a certain pressure on the gastric tube 1 inside the perforation 9 to ensure its stability and prevent it from moving, thus ensuring that the equipment will not get entangled.

[0035] The slider 10 has magnetism, and the sliding groove 6 has magnetism, and the slider 10 and the sliding groove 6 are magnetically matched.

[0036] Through the magnetic cooperation between the slider 10 and the sliding groove 6, the connecting block 11 can smoothly stay at the designated position when not subjected to external force, thus ensuring the continuity and stability of the laying activity of the gastric tube 1.

[0037] The limiting mechanism 5 includes a connecting rod 12. The connecting rod 12 is slidably installed inside the pipe-passing column 3. One end of the connecting rod 12 exposed outside the pipe-passing column 3 is fixedly installed with a lever 13. The other end of the connecting rod 12 is fixedly installed with a pressing block 14. A spring 15 is fixedly installed on the pressing block 14, and the other end of the spring 15 is fixedly installed inside the pipe-passing column 3.

[0038] When not subjected to external force, the spring 15 presses the pressing block 14, so that the pressing block 14 is inside the perforation 9. Furthermore, the pressing block 14 can smoothly press the gastric tube 1 inside the perforation 9, thereby limiting it and preventing accidental movement.

[0039] An accommodation cavity 16 for accommodating the pressing block 14 is provided inside the pipe-passing column 3.

[0040] When a force is applied to move the lever 13 upward, the movement of the lever 13 is smoothly transmitted to the pressing block 14 through the connecting rod 12, and then the pressing block 14 moves upward. At this time, the pressing block 14 enters the accommodation cavity 16, that is, the pressing block 14 is not inside the perforation 9, and the movement and insertion / extraction activities of the gastric tube 1 can be carried out smoothly.

[0041] Mounting pieces 7 are fixedly installed on both sides of the mounting plate 2. A safety pin 8 is movably installed on the mounting piece 7. By fixing the whole mounting plate 2 on the collar, it is convenient for installation and disassembly and does not interfere with the normal movement of the patient.

[0042] A pasting part 17 is inlaid and installed at the bottom of the mounting plate 2. The mounting plate 2 can also be pasted on the flat part of the patient's chest through the pasting part 17, so that the whole mounting plate 2 can move with the movement of the patient without affecting the patient's daily life.

[0043] The working process of the present utility model; first, an installation activity is carried out. The gastric tube 1 is passed through the perforation 9 on the tube-passing column 3 and laid as shown in Figure 1 . Then, according to actual needs, the whole device is installed at the corresponding position on the patient's body through the safety pin 8 or the pasting part 17.

[0044] When it is necessary to make a longer part of the end exposed for extraction or injection activities, by pushing the connecting block 11 with fingers, the tube-passing column 3 and the tube-winding column 4 on the slider 10 can be moved. Furthermore, the distance between the tube-passing column 3 and the tube-winding column 4 on the slider 10 and the tube-passing column 3 and the tube-winding column 4 fixed on the mounting plate 2 changes, so that the length of the tube body that can be laid on the mounting plate 2 changes.

[0045] After applying a force to move the lever 13 upwards, the movement of the lever 13 is smoothly transmitted to the pressing block 14 through the connecting rod 12, and then the pressing block 14 moves upwards. At this time, the pressing block 14 enters the accommodating cavity 16, that is, the pressing block 14 is not inside the perforation 9, and the redundant part of the gastric tube 1 can be smoothly drawn out, so that the end of the gastric tube 1 is smoothly exposed and reaches the corresponding length for extraction or injection activities.

[0046] Then, a reverse operation is performed to make the exposed part of the gastric tube 1 shorter.

[0047] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
