Description

Fistulization opening expanding device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a stoma expanding device.

Background

After a clinical patient carries out fistulization operation, the fistulization opening is easy to narrow due to the contraction effect of muscles around the fistulization opening after growth or the local scar formation of the fistulization opening and other reasons. The stoma often needs to be dilated periodically. The conventional stoma expansion is usually performed by manually expanding the stoma in a manner that fingers stretch into the stoma, which brings psychological discomfort to patients. The utility model discloses have special fistulization mouth expander among the prior art, need pull out the fistulization pipe during the use, insert the fistulization mouth with special fistulization mouth expander and carry out the expansion operation, take off the expander after the expansion is accomplished again, insert the fistulization mouth back to the fistulization pipe again, need wash the disinfection to the expander, accomodate the saving. The special expander is added, so that the operation is complicated and the convenience is not high.

Disclosure of Invention

The utility model aims to provide a stoma dilation device which is convenient to operate.

In order to solve the above technical problem, the present invention provides a stoma dilation device 10, which comprises a stoma tube, wherein a tube body 11 of the stoma tube is a flexible hollow round tube, and the stoma dilation device is characterized in that: an inflatable expanded air bag layer 12 which is isolated from the inside of the fistulation tube and is close to the outside of the fistulation tube is integrally arranged on the fistulation tube, and a first air-entrapping side tube 13 communicated with the inside of the expanded air bag layer is arranged on the outer wall of the expanded air bag layer; the stoma dilation device 10 further comprises a first stopper 14 which can be placed over the first gas-filling side tube 13 and a hand-held vacuum bulb 15 which can be connected to the first gas-filling side tube 13.

A hard rod 16 which facilitates the insertion of the fistulization tube into the stoma is detachably arranged in the fistulization tube.

A fixed air bag 17 for preventing the tube body from coming off from the stoma is further arranged on the outer wall of the front end of the tube body 11, a channel 18 for inflating and deflating the fixed air bag is vertically arranged along the outer wall of the tube body, the expanded air bag layer 12 is positioned outside the channel 18, and a second air-adding side tube 19 penetrates through the expanded air bag layer 12 and is communicated with the channel 18; a second plug 20 which can be taken down is arranged at the outer end of the second gas-filling side pipe 19.

According to the stoma expanding device, the inflatable expanding air bag layer is integrally arranged on the outer wall of the stoma, so that when the stoma is required to be expanded, the handheld negative pressure ball is communicated to the air-entrapping side tube, and a person holds the negative pressure ball with hand to inflate the air bag layer to expand, so that the stoma can be expanded. After the expansion is completed, only the negative pressure ball needs to be taken down, the gas in the air bag layer is released, the pipe body recovers to the original state, and then the plug is covered. Need not extra expander, need not extra disinfection and wash operations such as accomodate, it is very convenient to use. The utility model also provides a fixed air bag at the front end of the tube body, the air inflation and deflation channels of the fixed air bag are isolated between the expansion air bag layer and the tube body, and the fixed air bag and the tube body share one hand-held negative pressure ball. After the fistulization tube is inserted into a human body, the fixing air bag is inflated firstly to fix the fistulization tube and prevent the fistulization tube from falling out.

Detailed Description

As shown in figure 1, the utility model relates to a stoma dilation device 10, which is an improvement on the basis of the existing fistulation tube, wherein a tube body 11 of the fistulation tube is a flexible hollow round tube, one end connected with the outside of a body is thicker and is provided with an opening, an inflatable dilation air bag layer 12 isolated from the inside of the tube is arranged on the tube body 11 and attached to the outside of the tube body, and the outer wall of the dilation air bag layer is provided with a first air-adding side tube 13 communicated with an inflation space between the dilation air bag layer and the tube body.

The stoma dilation device 10 further comprises a first stopper 14 which can be placed over the first gas-filling side tube 13 and a hand-held vacuum bulb 15 which can be connected to the first gas-filling side tube 13.

A rigid rod 16 is detachably arranged in the fistulization tube to facilitate insertion of the fistulization tube into the stoma.

The stoma dilation device 10 according to the utility model is further provided with a fixation balloon 17 at the front end entering the body, which can play a role in fixing the device without coming out of the stoma. The fixed air bag is connected to the outer wall of the front end of the tube body 11 and isolated from the space in the tube body. In order to inflate and deflate the fixed air bag 17, a strip-shaped second air bag layer 18 is vertically arranged along the outer wall of the tube body, and an inflation channel of the fixed air bag is formed between the second air bag layer 18 and the tube body. The expanded airbag layer 12 is located outside the second airbag layer 18, and a second gas-filling side tube 19 passes through the expanded airbag layer 12 and the second airbag layer 18 and is communicated with an inflation channel of the fixed airbag for gas filling and gas releasing. A second plug 20 which can be taken down is arranged at the outer end of the second gas-filling side pipe 19.

Before the stoma dilation device 10 is ready to enter the body, the stoma tube is checked first, it is determined that the dilation balloon layer and the fixation balloon are in a deflation state, and the first plug and the second plug are both covered; inserting the hard rod 15 into the fistulization tube, then inserting the fistulization tube into the fistulization opening, and then taking out the hard rod; the second plug 20 is taken down, the handheld negative pressure ball 15 is connected with the second air-entrapping side tube 19 to be inflated, air enters the fixed air bag 17 to be expanded, and the width of the fixed air bag exceeds the width of the fistula, so that the fistulization tube is always fixed in a human body and cannot fall out of the fistula. And (3) removing the handheld negative pressure ball 15, covering the second air-entrapping side pipe 19 with a second plug 20 again, and keeping the fixed air bag 17 in a swelling state.

When the stoma is required to be expanded, the first plug 14 is taken down, the handheld negative pressure ball 15 is communicated to the first air-entrapping side tube 13, and the negative pressure ball 15 is pinched by hands, so that the expansion air bag layer is inflated to expand, and the stoma is expanded. After the expansion is accomplished, only need take off hand-held type negative pressure ball, the intraformational gas of expansion gasbag is fallen in the release, the body reconversion, cover again first end cap 14 can, it is very convenient to use, need not extra operations such as disinfection washing accomodate.
