Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a gastroenterology laxative. Background Art

[0002] A laxative is a device that passes liquid from the patient's anus into the patient's rectum, helping patients who are bedridden, have fecal incontinence, constipation, and other difficult defecation procedures to have bowel movements.

[0003] Existing laxatives usually include an introduction tube, a positioning balloon, a drainage tube, and a drainage bag located outside the patient's body. When the patient needs to defecate, first apply lubricant to the outside of the introduction tube, insert the introduction tube into the patient's anus, and then insert the positioning balloon and the drainage tube into the introduction tube until they reach the patient's anus. Use the balloon to flush gas or liquid to position the drainage tube relative to the patient's anus, and then inject liquid into the drainage tube to moisten the dry feces, and then draw it out from the drainage tube until it enters the drainage bag. After the drainage bag is full, the drainage bag is disassembled from the drainage tube and replaced with a new drainage bag, thereby assisting the patient in defecation. However, when the balloon is positioned, the patient's anal sphincter is in an open state for a long time, and the relaxation force of the anal sphincter will be affected, resulting in difficulty in defecation for the patient in the later stage. In addition, the balloon squeezes the inner wall of the rectum for a long time, which may cause edema of the inner wall of the rectum and cause anal infection. To this end, we propose a laxative for gastroenterology. Summary of the invention

[0035] The transmission mechanism 5 is installed on one side of the positioning airbag 3. The transmission mechanism 5 switches the multiple cavities 4 respectively. The transmission mechanism 5 can more conveniently switch the positioning airbag 3, thereby ensuring that the patient's sphincter is in a more comfortable state, reducing the possibility of anal edema of the patient, and facilitating the patient's defecation.

[0036] The transmission mechanism 5 includes an air cylinder 51 that passes through the positioning airbag 3. The air cylinder 51 is fixedly connected to the positioning airbag 3. A plurality of channels 52 that are connected to the single cavity 4 in sequence are provided on the surface of the air cylinder 51. A conductive tube 53 is provided inside the air cylinder 51.

[0041] According to the above embodiment, embodiment 2,

[0042] The outside of the drainage bag 1 is provided with a driving mechanism 8 for pulling or squeezing the drainage bag 1. The driving mechanism 8 includes a base 80, which can be placed on the ground or in a ward. One side of the base 80 is fixedly connected to an electric push rod 81, and the inside of the base 80 is provided with two stickers 82 respectively pasted on the surface of the drainage bag 1. The surface of the sticker 82 is coated with self-adhesive, which can facilitate the adsorption of the surface of the drainage bag 1. One of the stickers 82 is fixedly connected to the base 80, and the outside of the other sticker 82 is fixedly connected to a rotating seat 83, and the rotating seat 83 is rotatably connected to the base 80. The extended end surface of the electric push rod 81 is fixedly connected to a guide rod 84, and the guide rod 84 is inserted into the groove 85 of the rotating seat 83, and the guide rod 84 slides along the groove 85 of the rotating seat 83.

[0043] The end of the electric push rod 81 is fixedly connected to a piston plate 86, and the top of the base 80 is fixedly connected to a piston cylinder 87 that cooperates with the piston plate 86. The piston cylinder 87 is connected to the air cylinder 51 through a hose 88, and the inner wall of the piston cylinder 87 is provided with a spring 89.

[0044] After the patient inserts the drainage tube 2, the timer on one side of the electric push rod 81 can start the electric push rod 81 at a fixed time within 1-2 hours. After starting, the electric push rod 81 first extends and then retracts. When the electric push rod 81 extends, the electric push rod 81 drives the piston plate 86 to move, and the piston plate 86 pushes the gas in the piston cylinder 87 to pressurize. When the piston plate 86 moves in the opposite direction, the spring 89 opens to draw air into the piston cylinder 87 for subsequent use. The gas in the piston cylinder 87 directly pushes the push cylinder 75 to move through the hose 88, so that the positioning airbag 3 can be switched to a different cavity 4. At the same time, the electric push rod 81 will push the guide rod 84 to move. When 84 moves in the groove 85, it will push the rotating seat 83 to rotate, and the rotating seat 83 will push the drainage bag 1 to open or squeeze. When it is opened, negative pressure can be formed, so that the stool blocked in the patient's anus can be attracted to the drainage tube 2. When it is closed, the gas in the drainage bag 1 will be pushed away from the spring piece 3 9 and discharged. On the one hand, the cavity 4 can be switched in a positioned manner, and the stool in the drainage tube 2 can be moved during the switching, thereby reducing the possibility of stool blocking the drainage tube 2 and facilitating the continuous use of the drainage tube 2. Secondly, the excess gas in the drainage bag 1 can be discharged, the amount of stool collected by the drainage bag 1 can be increased, the frequency of replacement of the drainage bag 1 can be reduced, and the operation of medical staff is convenient.

[0046] An exhaust hole 54 is provided on the surface of the drainage bag 1, and a spring piece 3 9 is provided on the outside of the exhaust hole 54. Two symmetrically distributed one-way plates 10 are provided between the drainage bag 1 and the drainage tube 2. The two one-way plates 10 are both rubber plates, and the one-way plates 10 are elastic. A limit block 11 is provided on one side of the two one-way plates 10 close to the drainage tube 2, and the limit block 11 is fixedly connected to the drainage tube 2.

[0047] A guide bar 12 is provided in the drainage tube 2, one end of the guide bar 12 is fixedly connected to the inner wall of the drainage bag 1, and the other end of the guide bar 12 slides on the inner wall of the drainage tube 2. A slider 13 is fixedly connected to the end of the guide bar 12, and the slider 13 is slidably connected to the slide groove 14 in the drainage tube 2. The guide bar 12 is slidably connected to the one-way plate 10.

[0048] When the drainage bag 1 is flattened, the two one-way plates 10 reduce the gas entering the drainage tube 2, and the gas will be discharged from the spring three 9. In addition, during the pulling and flattening process, the guide bar 12 will be pushed to move in the drainage tube 2, thereby loosening the stool blocking the drainage tube 2, thereby facilitating the continuous use of the drainage tube 2 and facilitating the use of medical staff.

[0049] Both ends and the middle of the guide strip 12 are provided with raised patterns, and the patterns of the guide strip 12 can guide the feces.
