TECHNICAL FIELD
[0001] The utility model belongs to the field of anorectal function training and recovery technology, and particularly relates to a rectal pushing force training device. BACKGROUND
[0002] Constipation is a common digestive system problem, especially in the elderly, sedentary or postoperative rehabilitation patients. Its main symptoms include difficulty in defecation, reduced defecation frequency, and hard stool. Constipation not only affects the quality of life, but also can cause more serious complications, such as anal fissure, hemorrhoids, rectal prolapse, etc. Therefore, the treatment and management of constipation has become an important research direction in the medical field. At present, the treatment methods for constipation mainly include the following categories: drug treatment, diet and lifestyle adjustment, biofeedback training, surgical treatment. The existing technology generally has the problems of drug dependence, limited treatment range, expensive equipment and insufficient rectal pushing force training while relieving the symptoms of constipation. Chinese utility model ZL2015101192041 discloses an anus defecation training therapeutic instrument, although the technology uses a simulated fecal balloon, but its structure is oval, mainly aiming at anus training, if used for rectal training, the oval shape of the simulated fecal balloon cannot uniformly distribute the pressure on the intestinal tract, cannot completely stimulate the rectal receptors, and the simulated fecal material is gas, which has a gap compared with real solid stool.
[0003] Based on this background, it is urgent to develop a simple and effective device that focuses on rectal pushing force training to help patients recover natural defecation function. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims to provide a rectal pushing force training device which helps patients improve rectal pushing force and muscle coordination during defecation, thereby improving the quality of life.

[0006] The flexible bag is in a deflated state when not filled with simulated fecal material, and is inflated when filled with simulated fecal material; the temperature-sensitive hydrogel is a liquid material with temperature-sensitive properties, which is in a liquid state under certain temperature conditions, and changes to a gel state when the temperature changes; the Pluronic F127 temperature-sensitive hydrogel as known to those skilled in the art is composed of polyoxyethylene-polyoxypropylene-polyoxyethylene (PEO-PPO-PEO) triblock copolymer, and has unique temperature-sensitive properties and reversible temperature response properties, and is in a liquid state at room temperature (about 20-25℃) under a certain concentration such as 20-22% w / v, and forms a stable gel at a body temperature range of 36-37℃.
[0007] The support catheter not only serves to deliver the liquid, but also forms support for the flexible bag in the length direction, facilitating the medical staff to send the flexible bag together with the support catheter into the rectum; the liquid holes opened on the support catheter allow the liquid to enter from both ends of the flexible bag at the same time, so that the simulated feces formed are more evenly distributed.

[0012] Preferably, the support catheter is a polyvinyl chloride hose with an inner diameter of 4.0 mm and an outer diameter of 4.17 mm; for example, a Fr12 type balloonless urinary catheter produced by Yangzhou Jikang Medical Instrument Co., Ltd. can be used as the support catheter.

The flexible bag 1 is made of polyvinyl chloride with a thickness of 0.1 mm. The flexible bag 1 has a length of 15 cm and a diameter of 3 cm. The support catheter 4 is a polyvinyl chloride hose with an inner diameter of 4.0 mm and an outer diameter of 4.17 mm. The flexible bag 1 is a long strip-shaped bag with a gradually tapered lower part forming a bag opening. The bag opening is connected to a joint 5. The support catheter 4 passes through the joint 5 and extends into the flexible bag 1. The end of the support catheter 4 located inside the flexible bag 1 is a hemispherical surface. Liquid holes 6 are formed in the upper and lower parts of the support catheter 4. The end of the support catheter 4 located outside the flexible bag 1 is connected to a three-way valve 7. One end of a liquid supply pipe 8 and one end of a return pipe 9 are connected to the three-way valve 7. The other end of the return pipe 9 is connected to a liquid inlet valve 10 at the top of the simulated fecal material storage bag 3. The other end of the liquid supply pipe 8 is connected to a liquid outlet valve 11 at the bottom of the simulated fecal material storage bag 3. The liquid supply pipe 8 and the return pipe 9 are respectively provided with a delivery pump 2. The simulated fecal material stored in the simulated fecal material storage bag 3 is Pluronic F127 temperature-sensitive hydrogel.
[0020] Patient A has been suffering from chronic constipation for a long time and often needs to rely on medication to help defecate. The doctor suggests improving the symptoms by training rectal propulsive force and muscle coordination. The rectal propulsive force training device of the embodiment is used to train patient A. At the same time, the doctor assesses the patient's condition and makes plans for the next training. After multiple training, the patient's defecation ability improves and the constipation symptoms are alleviated.
[0021] The working principle and working process of the utility model:
[0022] Preparation before training:
[0023] 1. Disinfection and lubrication of the anus and rectum: Before placing the soft bag 1, the patient's anus and rectal area must be thoroughly cleaned and disinfected to ensure the safety and hygiene of the operation. Then, evenly apply medical lubricant on the surface of the soft bag 1 to reduce friction and ensure comfort during insertion.
[0024] 2. Placement of the soft bag: The patient is in a supine lithotomy position or a lateral position under the guidance of the doctor or professional nursing staff. Hold the support catheter 4 externally and slowly insert the soft bag 1 along with the support catheter into the patient's anus and into the rectum to the appropriate position.
[0025] 3. The simulated fecal material is a temperature-sensitive hydrogel. The simulated fecal material storage bag 3 containing the simulated fecal material needs to be stored at room temperature in advance. The temperature should be below 25℃ and in liquid form. The temperature should not be too low to avoid discomfort for the patient during subsequent injection.
[0026] Training process:
[0027] 1. Defecation process simulation: Ensure that the drainage valve 11 is open, the three-way valve 7 is open to the supply pipe 8 to the support catheter 4, and the three-way valve 7 is closed to the return pipe 9, and the inlet valve 10 is closed; start the delivery pump 2, slowly deliver the simulated fecal material in the simulated fecal material storage bag through the supply pipe 8, the support catheter 4, the liquid hole 6, and into the soft sac bag 1, gradually shape the soft sac bag 1, and the temperature-sensitive hydrogel changes from a liquid state to a gel state when heated, simulating feces; after the soft sac bag 1 is filled with simulated fecal material, the pressure generated gradually causes the rectum to produce a defecation urge; when the patient has a defecation urge or reaches a predetermined amount of simulated fecal material input, stop inputting simulated fecal material, instruct the patient to try to defecate with appropriate force, and finally expel the flexible sac bag 1; the doctor evaluates the patient's rectal propulsive force and muscle coordination based on the training to suggest that the difficulty of defecation can be appropriately increased or decreased in the next training, and the intensity of propulsive force training can be increased or decreased; as the patient's propulsive force gradually increases, muscle coordination also improves;
[0028] After the soft sac bag 1 is expelled, the simulated fecal material in the soft sac bag 1 can be recycled. The specific operation is as follows: ensure that the drainage valve 11 is closed, the three-way valve 7 is closed to the supply pipe 8 to the support catheter 4, and the three-way valve 7 is open to the return pipe 9, and the inlet valve 10 is open; place the soft sac bag 1 in a normal or low temperature environment, the temperature-sensitive hydrogel returns to a liquid state, start the return pipe 9 corresponding delivery pump 2, and draw the simulated fecal material in the soft sac bag 1 back into the simulated fecal material storage bag 3; the return pipe 9 and the three-way valve 7 can also be removed, the return pipe 9 can be replaced with an external discharge pipe, and the soft sac bag 1 can be directly discharged through the external discharge pipe for disposal.
