Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a stoma exhaust device and a stoma bag. Background Art

[0002] Stoma bags are medical supplies used to store human excreta, such as urine and feces. During colostomy, a section of the intestine in the abdominal cavity is pulled out for disease treatment and excreted through an opening in the skin of the abdominal wall. This type of patient cannot defecate normally due to intestinal damage, anal resection, etc., and needs to undergo colostomy surgery and use a stoma bag for excretion. During the use of the stoma bag, attention should be paid to strengthening local care and replacing it in time to avoid local infection.

[0003] According to the publication number: CN217793538U, the name: A stoma exhaust device and stoma bag, the technical problem it solves is: when the patient's intestines are exhausted, the stoma bag will swell, and in severe cases, the stoma bag may even leak, causing the patient's stoma to have a strong odor and a poor user experience; in addition, when the stoma bag leaks, a new bag must be replaced. If the stoma bag is replaced frequently, the cost of using the stoma bag will be too high.

[0004] However, there are still certain problems in the process of use. For example, it opens and closes the ostomy bag channel by adjusting the air-sealing mechanism. When exhausting, there is still a problem of slow gas flow rate, and the gas in the ostomy bag cannot be discharged quickly and effectively. In addition, its odor adsorption capacity is poor, causing the odor to flow into the air and affect the patient experience. At the same time, although the ostomy bag can be used many times, it still needs to be replaced after long-term use. When replacing the ostomy bag, the exhaust structure needs to be replaced together with the ostomy bag, and the replacement cost is relatively high. Utility Model Content
