Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bladder flushing training models, and in particular to a model and a model assembly for flushing training of blood clots or mucous secretions in the bladder. Background Art
[0002] Hematuria can cause blood clots to form in the bladder, resulting in difficulty in urination or catheter obstruction. For patients with bladder cancer undergoing bladder tumor transurethrocyte resection or in situ neobladder (intestinal bladder replacement) surgery, blood clots or mucus secretions in the bladder may cause poor urine drainage and bladder filling. In severe cases, it may even lead to complications such as shock and bladder rupture, posing a serious threat to the patient's health.
[0003] At present, there is a lack of standardized bladder flushing training models for medical staff; and the existing bladder catheterization teaching models cannot simulate the flushing of blood clots and mucus secretions in the bladder, which brings difficulties to the learning of medical staff. In addition, patients who undergo in situ neobladder surgery for bladder cancer have their neobladders made using the ileum, and the neobladders will regularly secrete intestinal mucus. If they are not flushed regularly and in a timely manner, there may be a risk of urethral obstruction and neobladder rupture. Therefore, family members also need to undergo effective simulation of flushing of blood clots or mucus secretions in the bladder, and receive training to facilitate timely and correct flushing of bladder secretions after the ileum replaces the bladder.
[0004] Therefore, developing a training model that can accurately and effectively simulate the flushing of blood clots or mucus secretions in the bladder is of great significance for improving the relevant business capabilities of medical staff and improving the self-maintenance ability of enteral bladder patients or their families for the new bladder.
