Description

Technical Field

[0001] This utility model relates to the technical field of intestinal obstruction catheter devices, specifically to an intestinal obstruction catheter with enteric-coated side holes for postoperative paralytic ileus. Background Technology

[0002] Intestinal obstruction is one of the most common surgical acute abdominal conditions, second only to biliary tract diseases and acute appendicitis in incidence. The causes and types of intestinal obstruction are numerous, and it can cause not only local changes in the intestines but also systemic pathological changes. Therefore, it is essential to promptly decompress and drain the obstructed area to reduce pressure. If the symptoms of intestinal obstruction cannot be relieved in time, emergency surgery is necessary, which carries significant risks for both the patient and the physician, and can lead to numerous postoperative complications.

[0003] Chinese patent CN201821914317.6 describes an intestinal obstruction catheter. This structure can effectively and promptly relieve intestinal obstruction symptoms, especially in the treatment of acute intestinal obstruction. It can rapidly reduce intestinal pressure, improve intestinal wall blood circulation, and alleviate intestinal wall edema. Preoperative drainage using an intestinal obstruction catheter can provide ample preparation time for surgery and reduce the occurrence of emergency surgical complications. However, in the existing structure, the opening is low, making absorption difficult; after prolonged use, the guidewire may protrude from the lateral hole, affecting the surgeon's operation. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides an intestinal obstruction catheter with enteric-coated side holes for postoperative paralytic ileus. This effectively solves the problems of existing technologies where the opening is too low, making absorption difficult and the guidewire protruding from the side hole after prolonged use, thus affecting the doctor's operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an intestinal obstruction catheter with enteric-coated side holes for postoperative paralytic ileus. The catheter includes a side hole, a central hole, a first side hole, a second side hole, a third side hole, and a fourth side hole. Two sets of balloons are provided at the bottom end of the catheter. The bottom end of the catheter is inserted and fixed to a plug. A steel ball is provided at the bottom end of the catheter. A venting tube is provided at the top end of the catheter.

[0009] Furthermore, the central hole is located between the two sets of balloons.

[0010] Furthermore, the side holes, center holes, first side holes, second side holes, third side holes, and fourth side holes are all equidistant arrays, and multiple sets are provided.

[0011] Furthermore, the balloon is filled with liquid or gas, and the two sets of balloons are divided into an anterior balloon and a posterior balloon according to their position, with the diameters of the two sets of balloons being 2-3 cm and 3-4 cm, respectively.

[0012] Furthermore, the plug has a hollow structure, and the plug is fixed to the conduit by an interference fit.

[0013] Beneficial effects

[0014] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0015] This invention features a catheter structure with multiple side holes. The top end is connected and fixed to the ventilator structure, while the bottom end is secured with a hollow plug structure for easy guidewire insertion. It includes an anterior balloon, a ventilation tube, a posterior balloon, and four interfaces for drainage and nutritional support, respectively. The anterior balloon has a diameter of 2-3 cm and is filled with water or gas. The ventilation tube has a large inner diameter to facilitate guidewire passage. The posterior balloon is large, with a diameter of 3-4 cm, to secure the intestinal tract and prevent reflux. Two steel balls facilitate catheter bends, shortening surgical time. The porous absorbent design increases patient recovery speed. Attached Figure Description
