Technical Field

The invention belongs to the technical field of stoma, and particularly relates to a stoma support expander.

Background

The colon is not emptied smoothly after the stoma is narrowed, which is easy to cause the frequent defecation or the thin excrement, and the clinical manifestation of low-level incomplete obstruction can also appear. The causes of stoma stenosis are mainly as follows: (1) colostomy stenosis is mostly due to ischemia. (2) Topical infections and skin openings too small. (3) The exposed serosa of colon is stimulated by feces, etc. to cause serositis, resulting in granulation tissue hyperplasia, followed by scar contraction, forming a ring-shaped stenosis.

The current treatment based on stoma stenosis is as follows: (1) patients with less stenotic stomas can be irrigated with a funnel or catheter. (2) When the narrow ring can pass through all the little fingers or the tips of the index fingers, the stoma is dilated by the fingers 1-2 times every day, and the degree of passing through all the index fingers is determined. Sufficient dilation often causes severe pain, easily producing bleeding and more scar tissue. (3) For symptomatic patients who are not effective in non-surgical treatment, or when the narrow ring cannot pass through the little finger, a ring of scar tissue on the periphery of the ostomy intestinal segment is removed circularly, the intestinal wall and the skin edge are sutured back intermittently by a thin intestinal thread, or the incisal edge is sutured back by a radial incision and a Z-shaped incision. (4) When examining the narrow end of the intestine, the physician needs to pay attention to whether there is any lump or hernia around the intestine, and if so, the physician needs to perform surgical treatment according to the specific situation.

However, the above treatment method cannot solve the problem, and the patient needs to dilate the stoma by fingers at intervals, so that the patient feels uncomfortable and is easy to infect, and secondary injury of the patient is aggravated by treating subsequent diseases through an operation.

Disclosure of Invention

The invention provides a stoma support expander, aiming at solving the problem caused by stoma stenosis.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the stoma support expander comprises a middle body, a ring body is arranged outside the middle body, an upper expansion ring is arranged at the upper end of the middle body, an air inlet is formed in the upper expansion ring and connected with an air inflation bag, a lower expansion ring is arranged at the lower end of the middle body, air enters the middle body and the lower expansion ring in sequence to realize expansion, and through channels are formed in the upper expansion ring, the middle body and the lower expansion ring.

Preferably, the upper expansion ring and the intermediate body adopt a balloon type ring body.

Preferably, the intermediate body adopts three layers of air bag type ring bodies, each layer of air bag type ring body is correspondingly connected with an air pipe, and each air pipe is inflated through an inflation bag.

Preferably, the expansion loop has a larger diameter than the intermediate body.

Preferably, the upper expansion ring adopts a ring body with expanded diameter.

Preferably, the lower expansion loop takes the shape of an inverted cone.

Preferably, a switch is arranged at the front end of the inflatable bag and used for adjusting the air injection amount.

The invention has the following beneficial effects:

the invention has simple structure, the dilator in an inflated state is placed in the stoma, gas is injected through the inflatable bag to expand the dilator, the upper and lower expansion rings can effectively prop against the periphery of the stoma to prevent the dilator from being extruded, a channel is arranged in the middle of the dilator to facilitate the retention of dirt at the stoma and solve the complications caused by the narrow stoma.

The invention adopts three layers of intermediates, thus meeting the requirements of the stoma with different sizes, and the outer layer is smeared with a lubricant and is conveniently placed in the stoma.
