Technical Field
[0001] The utility model relates to the technical field of disposable medical appliances, in particular to a double-hole opening urinary catheter which is convenient for draining urine from a bladder diverticulum. Background Art
[0002] Bladder diverticulum is a pouch-like structure formed by the bladder mucosa bulging outward through the weak bladder muscle layer. It can be congenital or secondary. The main type of urinary incontinence in children is congenital, mainly caused by congenital dysplasia of the local bladder muscle layer. The secondary type is more common in adults, with obstruction of the urethra and bladder neck, resulting in long-term increased pressure in the bladder, and bulging of the detrusor muscle after decompensation to form a diverticulum. After the formation of the bladder diverticulum, it can lead to increased residual urine volume, secondary infection, stone formation and upper urinary tract damage. Some patients need to squat and press the lower abdomen with their hands to urinate. Occasionally, there will be a second urination phenomenon. The first clear urine is discharged, and the turbid urine in the diverticulum is discharged later. The existing ones are divided into single-lumen and double-lumen, with different materials, but both are single-hole designs. Under cystoscopy, a catheter is placed in the bladder diverticulum to drain the urine in the bladder diverticulum, but the urine in the bladder cannot be drained out. The bladder diverticulum is a cystic structure, and the bladder is empty, and the diverticulum mouth is easy to close; a catheter is placed in the bladder, the catheter is in the bladder, and the urine in the diverticulum cannot be drained out. Therefore, it is necessary to design a double-hole open catheter that is convenient for bladder diverticulum drainage to solve the above problems. Utility Model Content
