Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a preoperative simulation stoma simulation device. Background Art

[0002] Improving self-care ability during hospitalization is an important issue for stoma patients. At present, the main nursing model in clinical practice is that nurses provide health education and psychological communication to patients. There are few opportunities for patients to learn stoma care by themselves before surgery. After surgery, patients are weak, have no endurance for activities, and have tube traction, etc., which leads to poor learning ability of stoma care and strong dependence. Therefore, many patients still have low self-care level for stoma when they are discharged from hospital, or even for a long time after discharge.

[0003] Due to the inability to master stoma-related nursing methods, postoperative stoma complications bring great distress to patients' lives, and common ones include exfoliative dermatitis and allergic dermatitis. These late psychological and physiological stresses can seriously affect physical, psychological and social functions. Therefore, postoperative stoma self-care is a nursing ability that stoma patients must have. Since patients are more likely to accept preoperative stoma-related information, providing stoma positioning and related knowledge education to patients who are about to have a stoma before surgery can reduce the occurrence of stoma-related complications and improve their quality of life. Therefore, it is necessary to design a device that allows patients to truly feel the existence of a stoma before surgery, facilitate the explanation of stoma-related knowledge, and provide stoma care guidance.

An annular air chamber 30 is coaxially arranged inside the silicone stoma body 20, and an inflation port 21 and a sealing head 22 for sealing the inflation port 21 are arranged on the silicone stoma body 20. The sealing head 22 is generally made of silicone or rubber. When inflation is required, the annular air chamber 30 can be inflated by piercing the sealing head 22 with an inflation needle. In actual operation, for safety reasons, to prevent accidental stabbing of the patient or puncturing of the silicone stoma body, a special safety inflation needle is generally used, such as a common needle such as a flat-head needle or a plastic needle. The front and rear side walls of the silicone stoma body 20 are provided with a telescopic portion 23 for radial expansion or contraction of the silicone stoma body 20, so that it can expand and become larger when inflated, and contract and become smaller when deflated, so as to simulate stomas of different sizes. Among them, the telescopic portion 23 is specifically an annular wrinkled portion or folded portion or a deformation portion with a smaller thickness, which can achieve the purpose of expansion by inflation and contraction by deflation.

[0023] The device also includes a pocket assembly 40 disposed outside the silicone stoma body 20, and a micro water pump 50 disposed inside the pocket assembly 40. The water outlet of the micro water pump 50 is connected to the inner hole 24 of the silicone stoma body 20 through a pipe 60. The overall structure is simple and easy to use. When in use, the silicone stoma body 20 and the pocket assembly 40 are directly pasted and fixed on the abdomen of the patient, and then a certain amount of liquid is added to the inside of the pocket assembly 40. The liquid inside the pocket assembly 40 is transported to the inner hole 24 of the silicone stoma body 20 through the micro water pump 50, and then flows downward and flows back into the pocket assembly 40, thereby simulating the situation of a real stoma, allowing patients to truly familiarize themselves with the daily operation of the stoma before surgery, and can adapt to the use and care of the stoma more quickly, which is convenient for improving the patient's postoperative nursing ability and psychological adaptation to the intestinal stoma, and can greatly shorten the patient's hospitalization time.

When assembled in place, the rear end face of the tubular joint is in close contact with the annular bottom plate 10 to play a sealing role. Through the cooperation of the positioning groove 1011 and the positioning protrusion 421, the purpose of easy rotation fixation or disassembly can be achieved, which is convenient for the daily use and care of the patient.
