Description

ileostomy dilator

technical field

The invention relates to the technology of medical equipment, in particular to the technology of an ileostomy dilator.

Background technique

Ileostomy is an artificial opening in the patient's abdominal wall in order to treat certain diseases, and a section of intestinal tube is pulled out of the opening, and is turned over and sewn to the abdominal wall, thereby forming an intestinal stoma, and the patient's stool is excreted through the stoma. . Stoma stenosis is a common complication of ileostomy. There are two reasons for the formation of stoma stenosis: 1) In some patients, due to the strong abdominal wall muscles, the bowel can be clamped during contraction, affecting defecation; 2) due to surgical stimulation of ileal edema.

Patients with stoma stenosis must be treated in time, otherwise it will cause intestinal obstruction or even more serious complications. There are two existing stoma stenosis treatments. The first method is that the doctor inserts his finger into the stoma to perform stoma expansion. The disadvantage of this method is that the stoma cannot be continuously expanded (the doctor cannot expand the stoma around the patient 24 hours); the second method It is to insert the catheter into the stoma for dilation. The disadvantage of this method is that once the catheter is blocked, the catheter needs to be pulled out for treatment.

Further, the mushroom head is a soft cavity.

Further, a cavity wall airbag that can be inflated and deflated is formed on the cavity wall of the mushroom head, and the right part of the main conduit is provided with a mushroom head intake valve for controlling the inflation and deflation of the cavity wall airbag on the cavity wall of the mushroom head.

Further, the main conduit is provided with a flushing channel, the water outlet of the flushing channel is connected to the inner cavity of the mushroom head, and the water inlet of the flushing channel is located at the right part of the main conduit.

Further, a cold light light source is provided on the right part of the main pipe, and a light source channel for guiding the emitted light of the cold light light source to the mushroom head is provided on the main pipe.

In the ileostomy dilator provided by the present invention, through the cooperation of the main catheter and the expansion balloon, the expansion balloon can be guided to the to-be-expanded part of the stoma by the main catheter, and the expansion degree of the expansion balloon can be controlled according to the diameter of the stoma, that is, Stoma expansion can be achieved, and if necessary, the lumen of the fungus head and the main catheter can be flushed with water through the irrigation channel, and the feces in the fungus head can be squeezed by the cavity wall balloon on the cavity wall of the fungus head without pulling out the main tube. The pipe can clear the blockage.

FIG. 1 is a schematic structural diagram of an ileostomy dilator according to an embodiment of the present invention.

Detailed ways

The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention. Any similar structures and similar changes of the present invention shall be included in the protection scope of the present invention. The commas in all indicate the relationship of and.

As shown in FIG. 1 , an ileostomy dilator provided by an embodiment of the present invention is characterized in that: it comprises a main catheter 1 and an expansion balloon 2;

The expansion balloon 2 is annular, the main conduit 1 passes through the annular hole of the expansion balloon 2 in a tight fit manner, and the expansion balloon 2 is provided with an expansion intake valve 4 for controlling inflation and deflation of the expansion balloon;

The left end of the main pipe 1 is fixed with a mushroom head 3, the mushroom head 3 is a hollow cavity, and the cavity wall of the mushroom head 3 is provided with a fecal water outlet and a plurality of fecal water introduction ports 7, wherein the fecal water is The outlet is butted with the left end nozzle of the main conduit 1;

The main pipe 1 is provided with a flushing channel, the water outlet of the flushing channel is connected to the inner cavity of the mushroom head 3, and the water inlet 5 of the flushing channel is located on the right part of the main pipe; and a plurality of bypass ports are arranged on the flushing channel, The lumen of the flushing channel and the lumen of the main conduit are communicated with each other through various bypass ports on the flushing channel;
