Detailed Description

As shown in fig. 2, 7 and 11, the urine dynamic monitoring system with the valve automatically reset comprises a monitoring unit 1, a controller 2, a power source 3, a shell 4 and a locking mechanism 5, wherein the monitoring unit 1 comprises a main tube 1100, a pressure sensor 1200, a control valve 1300, an electronic tag 1400 and a shell 1500.

The main tube 1100 is a hollow tube, which can be made of plastic material by injection molding, and has a monitoring cavity inside for liquid to pass through, one end of the monitoring cavity is provided with a liquid inlet 1110 for communicating with a catheter inserted into a human body, and the other end is provided with a liquid outlet 1120 for connecting with a liquid collecting bag for storing liquid.

The main tube 1100 may be a single hollow tube or a plurality of hollow tubes connected together.
