Technical field

The invention relates to the field of medical equipment, and in particular to a disposable enema.

Background technique

A commonly used clinical operation is enema, which is to insert a catheter from the anus through the rectum and infuse liquid. It can stimulate intestinal peristalsis, soften and remove gas in feces, and has the effects of cooling, inducing labor, diluting intestinal poisons, reducing absorption, and cooling patients with high fever. In addition, it can also achieve therapeutic purposes such as supplying drugs, nutrition, and moisture. The anal canal of the disposable enema currently used clinically is about 24cm long, about 8mm in diameter, and opens at the end of the anal canal and on both sides of the end. However, this length cannot meet the needs of patients with deep pneumatocele and deep lesions. The end opening cannot meet the requirements of long intestinal lesions and uniform infusion of liquid. Moreover, the anal canal is a flexible tube, which is difficult to insert into a deep position. At the same time, it is difficult to insert into a position where feces accumulates.

The plurality of first liquid outlets 113, the first air bag 131, the plurality of second liquid outlets 114 and the second air bag 132 distributed sequentially from the first section on the enema hose 11 can not only effectively break up feces, but also facilitate the enema operation. That is to say, the enema tube 1 can be prevented from flowing out of the intestinal tract along with the enema liquid, and the action area and length of the enema liquid can also be increased, so that the enema liquid can be fully sprayed on the longer lesions. Preferably, the outer wall 117 of the enema hose 11 is provided with a length measurement mark 115 in centimeters to measure the insertion depth of the enema tube 1 . Preferably, the enema tube 1 is a transparent tube to facilitate observation and measurement of the length of the enema tube 11 inserted into the body. Furthermore, the outer surface of the enema tube is also marked with a scale to facilitate the nurse to check the insertion depth of the anal canal. Preferably, both the first liquid outlet 113 and the second liquid outlet 114 are circular through holes, and the arrangement of multiple first liquid outlets 113 and multiple second liquid outlets 114 is They are all arranged in a matrix type. The circular liquid outlet can ensure the largest water outlet area and improve the efficiency of enema. At the same time, the matrix type arrangement can make the enema liquid spray more evenly.

The spiral tube 12 is located between the inner wall 116 and the outer wall 117 and includes a first end 121 and a second end 122. The first end 121 is sealed and integrally fixed on the head end 111 of the enema hose 11. The spiral tube 12 is coiled around the inner wall 116 and It is coiled from the head end 111 of the enema hose 11 to the tail end 112 of the enema hose 11 . The second end 122 seals through the outer wall 117 and is located on one side of the tail end 112 of the enema hose 11 .

The spiral tube 12 is integrally connected with the inner wall 116 and the outer wall 117, which can fully reduce the overall outer diameter of the enema tube 1 while ensuring the function, ensuring that the enema tube 1 can smoothly penetrate into the intestine. Preferably, the second end 122 of the spiral tube 12 is provided with a second heparin cap 123 to promptly block the second end 122 after gas or liquid is injected into the spiral tube 12 to avoid overflow.

The airbag tube 13 is located between the spiral tube 12 and the inner wall 116 and is integrally fixed on the inner wall 116. One end of the airbag tube 13 is connected to the second airbag 132. The injection end 134 of the airbag tube 13 passes through the outer wall 117 and is located at the end of the enema hose 11. The other side of the tail end 112. Preferably, a first heparin cap 135 is provided on the injection end of the balloon tube 13 to promptly block the injection end 134 after gas or liquid is injected into the balloon tube 13 to avoid overflow.

When not in use, both the first air bag 131 and the second air bag 132 are automatically tightened and bound to the enema hose 11, no liquid is injected into the spiral tube 13, and the entire enema tube 1 is in a soft state.

In normal use, first hang the enema bag 2 on the infusion pole, and then insert the enema tube 1 into the intestine from the patient's anus. Since the enema tube 1 is a flexible tube, it will be difficult to insert it after a certain distance. When the spiral tube 12 is filled with liquid or gas, the effect of straightening the enema tube 1 is achieved, thereby facilitating the insertion of the enema tube 1 . After being inserted into the lesion position, the enema solution cannot fully exert its effect due to the accumulation of feces, resulting in waste and prolonging the treatment time. At this time, a certain amount of gas or liquid is injected into the balloon tube 13 through the injection end 134, so that the first balloon 131 and the second air bag 132 are inflated to achieve the purpose of crushing feces. On the other hand, the first air bag 131 and the second air bag 132 are opened to fix the enema tube 1 in the intestine to prevent the enema tube 1 from moving along with the flow of the enema liquid. Back away. A plurality of first liquid outlets 113 and a plurality of second liquid outlets 114 spray enema liquid to the lesion at the same time, and at the same time, the enema liquid discharges a lot of liquid, has a wide range and a large area, so that the feces in the feces accumulation area is quickly diluted. , and the plurality of first liquid outlets 113 and the plurality of second liquid outlets 114 are evenly distributed on the enema hose 11, and the total action distance is longer, which can meet the requirements of long intestinal lesions and even injection of liquid. .

Preferably, an overflow prevention device 3 is provided on the outside of the enema tube 1, and a pipe 31 for the enema tube 1 to pass through is provided inside the overflow prevention device 3. The overflow prevention device 3 is gourd-shaped and includes an inner end 32 and an outer end. The end 33, the port of the internal end 32 is in the shape of a sharp cone for easy insertion into the body, the external end 33 is tapered, and the outer diameter at the intersection of the internal end 32 and the external end 33 is smaller than the maximum external diameter of the internal end 32 and the maximum external diameter of the external end 33 outer diameter. The anti-overflow device can be inserted into the anus. Through the special design of the shape, the inner end of the body is fixed in the anus and is not easy to protrude, thereby preventing leakage of the enema liquid at the anus. The pipe 31 in the anti-overflow device 3 is more conducive to the insertion of the enema tube 1. Enter without hindrance. The gourd-shaped design of the overflow prevention device 3 not only makes it easier for the internal end 32 to be inserted into the anus, but also utilizes the automatic shrinkage of the anus to make the anus automatically shrink between the internal end 32 and the external end 33 after the internal end 32 enters the anus. The depression between them achieves a perfect anti-overflow effect. Preferably, the port of the internal end 32 is provided with a rubber ring 34 to prevent leakage to prevent enema liquid and feces from overflowing from the pipe 31 .
