Description

Technical Field

[0001] The utility model belongs to the field of medical catheter fixation, and particularly relates to an intestinal obstruction catheter fixation device. Background Art

[0002] Intestinal obstruction refers to a disease in which the contents in the intestine cannot be normally transported and pass through the intestine due to various reasons. It is a common surgical disease, and the main causes of onset include postoperative intestinal adhesion, colorectal tumors, intussusception, hernia, intestinal volvulus, etc. The most common symptoms of intestinal obstruction include paroxysmal abdominal pain, vomiting, inability to defecate and exhaust, abdominal distension, etc.

[0003] An intestinal obstruction catheter is a catheter used for decompression and reduction of small intestinal obstruction below the duodenum. By inserting the catheter into the gastrointestinal tract, functions such as providing nutritional support, drug infusion, or emptying can be achieved. An intestinal obstruction catheter fixation device is used to fix the intestinal obstruction catheter on the patient's body surface, ensuring that the intestinal obstruction catheter remains stable on the patient's body surface, can be in the correct position and perform the functions of the catheter, and will not accidentally move or fall off.

[0004] The existing intestinal obstruction catheter fixation devices are not fixed firmly enough and cannot provide sufficient stability, resulting in the catheter slipping or shifting, which may affect the treatment effect and even cause additional harm to the patient. Moreover, due to individual differences in the patient's body shape, condition, etc., the existing intestinal obstruction catheter fixation devices cannot meet the needs of all patients, which leads to poor fixation effect and even inability to fix the catheter. And due to the different sizes of the catheters, the existing intestinal obstruction catheter fixation devices cannot adapt to all catheters, which may cause the catheter to be compressed or folded, resulting in poor patency of the catheter. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an intestinal obstruction catheter fixation device, which can stably fix different types of intestinal obstruction catheters on the body surfaces of patients with different body shapes.
