Description

Urethra support tube for continuous urethra flushing Technical Field The utility model relates to the technical field of medical appliances, in particular to a urethra bracket tube for continuous urethra flushing. Background The urethral stent tube is a medical instrument commonly used in urinary surgery and is mainly used for maintaining the patency of the urethra, draining urine or performing postoperative irrigation. In the clinic, particularly after urethral surgery or long-term indwelling catheterization, the urethra is often flushed to prevent blockage of blood clots, secretions or tissue debris and to keep the part clean. However, the existing urethral stent tube can meet the requirement of continuous flushing, but has obvious defects in the aspect of realizing rapid and reliable on-demand flushing control, especially in the scene of needing short-time and repeated pulse flushing or instant flushing, such as instant dredging of postoperative blood clot or tissue fragment blockage, intermittent cleaning of accumulation of secretion of a long-term indwelling catheterized patient, short-time pushing of local administration in the urethra, auxiliary flushing for keeping clear view in cystoscope operation, instant maintenance of the unobstructed state of the urethra after the patient moves, and the like. The normal reliable closing can avoid continuous uncontrolled outflow of flushing liquid, reduce resource waste, reduce irritation and infection risk caused by long-term liquid flow impact of urethral mucosa, and the instant controllable opening can realize quick response as required by medical staff, support pulse flushing to loosen and discharge blockage more effectively, and facilitate short-time drug infusion or local treatment, thereby improving flushing effect and treatment pertinence and simultaneously reducing medical operation burden. Therefore, the integrated flushing control structure which can be closed normally and reliably and can be opened and continuously flushed in a timely and controllable manner on the premise of meeting the continuous flushing requirement is lacking in the prior art, and the integrated flushing control structure is difficult to meet the comprehensive requirements of timeliness, liquid saving and operation convenience in clinic. Disclosure of utility model The utility model aims to provide a urethra bracket tube for continuous urethra flushing, which solves the problems in the background technology.
