Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ostomy bag cleaning technology, specifically relating to a one-piece ostomy bag cleaner. Background Technology
[0002] One-piece ostomy bags are suitable for postoperative patients who need to collect excrement and protect the skin around the stoma. Their indications are mainly related to the type of intestinal or urinary tract stoma, the patient's physical condition, and nursing needs, and should be selected based on a physician's assessment. I. Main Indications: Postoperative patients with enterostomies: including colostomies (such as after rectal cancer or colon cancer surgery), ileostomies (after Crohn's disease or ulcerative colitis surgery), etc., for collecting intestinal excrement. Both temporary and permanent stomas can be used; the appropriate size should be selected according to the stoma location (single-lumen or double-lumen). Postoperative patients with urinary tract stomas: suitable for patients after cystectomy or urinary diversion (such as bladder cancer or neurogenic bladder), for collecting urine. An ostomy bag with an anti-reflux design should be selected to reduce the risk of infection. One-piece ostomy bags cannot be replaced and generally require flushing.
[0003] A portable ostomy bag rinsing bottle, as disclosed in utility model publication CN208243676U, includes a bottle body with an externally threaded spout, a bottle cap with an internally threaded spout matching the external thread, and a rinsing tube. The spout also has an internal thread. One end of the rinsing tube is a connecting end with an externally threaded spout matching the internal thread, and the other end is a water outlet for rinsing the ostomy bag. The height of the bottle body is less than the length of the rinsing tube, and the sum of the heights of the bottle body and the bottle cap is greater than the length of the rinsing tube. The water outlet has multiple water outlet holes. The height of the bottle body is 15-20 cm. The bottle body is made of soft plastic. This design has a simple overall structure, is easy to carry, simple to manufacture, and simple to operate. Soft plastic is also relatively common, resulting in low overall cost. The height of the bottle body is less than the length of the rinsing tube, and when the rinsing end is placed inside the bottle body, a section of the rinsing tube is outside the bottle body for easy leverage.
[0004] In the above-mentioned technical solutions, the rinsing wastewater in the ostomy bag is prone to flow back into the bottle during rinsing, causing water pollution in the bottle and affecting the subsequent rinsing effect. At the same time, the rinsing pressure is not easy to control, making it difficult to quickly rinse the dirt in the ostomy bag. Furthermore, there is no auxiliary fixing structure for the ostomy bag at the connection between the ostomy bag and the bottle, which can easily cause the ostomy bag to slip off or wastewater to overflow. Therefore, we propose a one-piece ostomy bag cleaner. Utility Model Content
