Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a gastrostomy catheter fixing and anti-pulling structure. Background Art

[0002] As we all know, gastrostomy catheter is a medical device widely used in the medical field. It is mainly used for patients who cannot eat normally orally due to various reasons but still have gastrointestinal function. It is directly inserted into the stomach through surgery or endoscopy, thereby establishing a nutrient delivery channel, allowing nutrient solution, medicine, etc. to directly enter the stomach and be absorbed and utilized by the human body.

[0003] Existing gastrostomy catheters are all fixed with balloons. The balloons are usually made of silicone and have thin walls. They are easily broken by the influence of gastric acid for a long time, causing the gastrostomy catheter to fall off. Moreover, after the balloon is inflated, the balloon will leak over time, causing the volume to decrease, resulting in unstable fixation and easy to cause problems such as stoma infection.

[0004] The existing patent (publication number: CN221932826U) discloses a percutaneous gastrostomy catheter fixer, which belongs to the field of medical device technology, and comprises: an outer tube, which is arranged at the center position of a plurality of sutures arranged in a circular array, and a support flap is arranged at the lower end of the outer tube, and the support flap is used to fix the outer tube on the stomach wall; an inner tube, which is arranged in the outer tube, and a gastrostomy catheter is arranged in the inner tube, and the lower end of the inner tube is connected to the support flap; an outer tube fixing unit, and the outer tube fixing unit is used to fix the outer tube to the outside of the abdominal wall. The percutaneous gastrostomy catheter fixer of this utility model is easy to disassemble, and is fixed by a support flap, so it has good fixation, is not easy to fall off and move, and is easy to replace the gastrostomy catheter, which saves the patient's treatment costs, has good anti-seepage effect, and shortens the operation time.

[0005] In view of the above problems, the existing patents provide solutions. However, when the gastrostomy catheter is fixed, due to the lack of a traction protection and fixing structure for the catheter, the catheter will be displaced when it is pulled, reducing the stability of the catheter when it is limited. In addition, there is a lack of an auxiliary preheating structure, and the nutrition cannot be preheated when the catheter delivers nutrition, reducing the efficiency of patient treatment.

[0006] To this end, a gastrostomy catheter fixing and anti-traction structure is proposed. Utility Model Content

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A gastrostomy catheter fixing and anti-pulling structure comprises a gastrostomy catheter body 1, a preheating mechanism 2 and a protection mechanism 3, wherein the preheating mechanism 2 is sleeved on the top of the surface of the gastrostomy catheter body 1, and the protection mechanism 3 is clamped on the surface of the gastrostomy catheter body 1;

[0029] The preheating mechanism 2 includes a positioning tube 21, a limiting base 22, a heating ring 23, a connecting head 24 and a connecting tube 25.

[0030] In this embodiment: by setting a gastrostomy catheter body 1 and a preheating mechanism 2, the gastrostomy catheter body 1 is an existing gastrostomy catheter structure, the positioning tube 21 can connect the gastrostomy catheter body 1 with the limiting base 22, and an external nutrition delivery device is connected through the connecting tube 25 to deliver nutrition to the gastrostomy catheter body 1 through the limiting base 22, and the connector 24 can be connected to an external power supply to provide power support for the heating ring 23, so that the heating ring 23 can preheat the nutrition in the limiting base 22, increase the temperature when delivering nutrition to the patient, and improve the efficiency of patient treatment.

[0031] Specifically, Figure 3As shown, the protection mechanism 3 includes a support component 31 and a limit component 32 . The support component 31 is clamped on the surface of the gastrostomy catheter body 1 , and the limit component 32 is fixedly connected to the surface of the support component 31 .

After the connecting block 313 is connected to the positioning ring 321, the gastrostomy catheter body 1 at the anti-slip tube 311 can be supported and limited. When the gastrostomy catheter body 1 is pulled, the anti-slip tube 311 can transfer the force to the support plate 312, and the support plate 312 transfers the force to the positioning ring 321 through the connecting block 313, so that the positioning ring 321 transfers the force to the abdominal patch 323 and the positioning patch 322 for sharing.

[0040] In this embodiment: by providing a heat-insulating tube 324 and a heating plate 325, the heat-insulating tube 324 can perform heat-insulating treatment on the connection between the heating plate 325 and the gastrostomy catheter body 1, so as to prevent the heating plate 325 from transferring heat to the gastrostomy catheter body 1; the heating plate 325 is an existing warming patch, which can heat the abdominal patch 323 to increase the comfort of the user when using it; by providing a heat-conducting plate 326 and a heat-insulating ring 327, the heat-conducting plate 326 can evenly transfer the heat of the heating plate 325 to various parts of the abdominal patch 323, thereby further increasing the stability when keeping the user warm; the heat-insulating ring 327 can perform heat-insulating treatment on the connection between the heat-conducting plate 326 and the positioning ring 321.

[0041] Working principle: First, place the gastrostomy catheter body 1 on the affected part of the patient, then stick the abdominal patch 323 and the positioning patch 322 on the surface of the affected part, and then connect the connecting head 24 to an external power supply. When it is necessary to deliver nutrient solution, the connecting tube 25 can be connected to the nutrient solution delivery equipment. When the nutrient solution flows through the limiting base 22, the heating ring 23 will heat the nutrient solution in the limiting base 22 by heating the limiting base 22. After heating, the nutrient solution will be delivered to the positioning tube 21 through the positioning tube 21, and finally flow into the patient's stomach. When the gastrostomy catheter body 1 is affected by traction, the anti-detachment tube 311 will transfer the traction force to the support plate 312, the support plate 312 will transfer the force to the connecting block 313, the connecting block 313 will transfer the force to the positioning ring 321, and the positioning ring 321 will transfer the force to the positioning patch 322 and the abdominal patch 323 respectively.
