Description

Technical Field

[0001] The utility model relates to the technical field of fistula tubes, in particular to a combined fistula tube. Background Art

[0002] To put it simply, an ostomy is to cut off the section of the intestine with the mass (including the mass), make a new opening in the belly for the upper section of the intestine, pull it out, and defecation will come out from here. The most common ostomies are: valve tube gastrostomy, suprapubic cystostomy, double-opening ileostomy, single-opening ileostomy, cecostomy, transverse colostomy, pyelostomy and nephrostomy, cholecystostomy, jejunostomy. A fistula refers to a pathological connection between the outside of the body and a cavity organ or between two cavity organs caused by an abscess. Sexual pus drainage ducts usually have two or more openings. The former is called an external fistula, which has an external opening and an internal opening, such as intestinal fistula, anal fistula, etc. The latter is called an internal fistula, which has only an internal opening, such as rectal bladder fistula, gastrocolic fistula, etc. The fistula overflow varies due to the different organs connected to it, which can be digestive juice, feces, urine or other secretions. The traditional fistula tube is an integral type. If dust occurs in the fistula tube, it needs to be replaced, and the specific part cannot be replaced, so the fistula tube needs to be replaced as a whole, which increases the cost of use. Therefore, a combined fistula tube is proposed.

[0003] After searching, the patent announcement number CN217548580U discloses an anti-slip gastrostomy tube, comprising: a fistula tube; an expansion component, the expansion component is installed on the outside of the fistula tube, and is used to adjust the outer diameter of the fistula tube, wherein the expansion component comprises: a sleeve, the sleeve is sleeved on the outside of the fistula tube, and the sleeve is divided into two sections, one section is connected to the outer wall of the fistula tube, and the other section slides on the outer wall of the fistula tube, a coating, the coating is connected between the two sections of the sleeve, when the sleeves at both ends are close to each other, the coating expands outward, and a coil, the coil surrounds the inner wall of the sleeve, and both ends of the coil extend out of the sleeve, the coil is used to connect the sleeve with the inner tube, however, the fistula tube in the prior art document is an integral type, if dust occurs in the fistula tube, it needs to be replaced, and the specific part cannot be replaced, so the fistula tube needs to be replaced as a whole, which increases the use cost, and the guide head of the fistula tube in the prior art document is a cylinder, when used on the patient, it is easy to cause pain to the patient, thereby reducing the comfort of the patient when using it.
