Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, and particularly relates to a urinary dynamic urine automatic drainage device. Background Technique

[0002] Urodynamic examination is a means to study the physiological processes of urine storage and urination in the lower urinary tract and their functional disorders by detecting the pressures, flow rates, and bioelectric activities of various parts of the lower urinary tract according to the principles of fluid mechanics, using electrophysiological methods and sensor technologies, and is an important method for evaluating the types and degrees of lower urinary tract dysfunction. The urethral manometry catheter generally includes a manometry catheter and an infusion catheter, such as the urodynamic manometry catheter disclosed in Patent CN215841138U; before the existing technology manometry, the catheter body connected with the manometry catheter and the infusion catheter is inserted into the patient's urethra until the urethral orifice, and then further pushed into the bladder, and then the manometry catheter is connected with the manometry system; during the manometry, normal saline is perfused from the infusion catheter to fill the bladder to the maximum capacity of about 500 mL, and the patient needs to excrete urine when the bladder manometry tube is indwelling. Once the patient cannot urinate by himself, the medical staff needs to use a syringe to aspirate urine, otherwise the urethral manometry cannot continue; due to the relatively thin manometry tube body, the method of aspirating urine with an injector is time-consuming, laborious and inefficient.
