Title:
FLOW STOPPER PREVENTING BACKFLOW OF URINE
Document Type and Number:
WIPO Patent Application WO/2020/082321
Kind Code:
A1
Abstract:
A flow stopper preventing the backflow of urine, comprising a urinary tube connector (10), a flow stopping valve (20), and a urinary bag connector (30). The flow stopping valve (20) is a membrane material. A flow channel (201) runs through the front and rear ends of the flow stopping valve (20). The flow channel (201) is provided with a front-end inlet (202) and a rear-end outlet (203). The front-end inlet (202) is in communication with a valve port (13) of the urinary tube connector (10). The rear-end outlet (203) is a flat slit. A channel (301) of the front and rear end surfaces of the urinary bag connector (30) is provided with a front-end port (302) and a rear-end port (303) connected to a urinary bag tube. The flow stopping valve (20) is arranged within the channel (301). Moreover, the rear-end outlet (203) of the flow channel (201) is directly opposite to the rear-end port (303) of the channel (301). With the employment of the membrane material serving as the flow stopping valve (20), and the rear-end outlet (203) of the flow channel (201) being a flat slit, when urine flows through the rear-end outlet (203), due to the extendibility of the membrane, the urine is drained when the urine opens up the rear-end outlet (203); and when the urine is fully drained from the rear-end outlet (203), the rear-end outlet (203) closes due to the extendibility of the membrane, thus preventing the backflow of the urine, and preventing a patient from being infected. Moreover, this is structurally simple, convenient, and practical and, compared with a conventional flow stopper, automatically prevents the backflow of urine.
