Further, referring to fig. 5, in order to prevent the urine collection bag 3 from being accidentally touched or dropped from the hook body 212 in case of accidental collision, the hook body 212 of the present invention is provided as an inner hook type hook body which facilitates sliding of the urine collection bag 3. Specifically, the hook body 212 has a urine collection bag hanging portion 2121 fixedly connected to the hook base 211 and extending in the horizontal direction, a urine collection bag slide-in portion 2122 formed to extend obliquely upward along the distal end of the urine collection bag hanging portion 2121, and a urine collection bag blocking portion 2123 formed at the distal end of the urine collection bag slide-in portion 2122 and extending upward in the vertical direction. Through the design of the structure of the hook body 212, the urine collecting bag 3 is convenient to hang, and under the condition of mistaken collision, the urine collecting bag is firmly hung and is not easy to fall off.

Referring to fig. 3 and 5, the elastic piece of the microswitch 41 extends from the side of the hook base 211 to the side of the urine collection bag hanging part 2121 in the direction in which the urine collection bag 3 is hung. When the urine collection bag 3 is hung, the hook of the urine collection bag 3 is hung on the urine collection bag slide-in portion 2122 of the hook body 212, and the hook of the urine collection bag 3 slides down to the urine collection bag hanging portion 2121 along the urine collection bag slide-in portion 2122, and at this time, the hook of the urine collection bag 3 touches the elastic piece of the microswitch, and the microswitch 41 is operated. The microswitch 41 is communicated with a prompt circuit of the main control unit 5, the prompt circuit sends out a prompt signal that the urine collection bag 3 is hung in place, and information that the urine collection bag 3 is hung is displayed on the display element 6. The weighing sensor 22 acquires the weight data of the urine collection bag 3 in real time and transmits the weight data to the main control unit 5, and the main control unit 5 processes and stores the weight data and then displays the related data on the display element 6 in a digital form. The data displayed may be urine volume or urine weight. The urine collection bag suspension portion 2121 is horizontally arranged, the urine collection bag 3 can be ensured to be stably suspended and not easily shake, so that the external interference of the weighing sensor 22 is reduced, the measurement accuracy of the weighing sensor 22 is improved, the urine collection bag sliding portion 2122 is inclined to facilitate the suspension of the urine collection bag 3, meanwhile, when the urine collection bag 3 is suspended along an inclined angle, under the action of gravity, the urine collection bag 3 slides into the urine collection bag suspension portion 2121 at a certain acceleration, the microswitch 41 can be more easily triggered, the reliability of the urine collection bag 3 identification by the urine volume monitoring device is improved, and the urine collection bag blocking portion 2123 can further prevent the phenomenon that the urine collection bag 3 falls off from the hook body 212 due to misoperation. The whole hook body 212 has a simple and small structure, is convenient to use and has low manufacturing cost.

Further, referring to fig. 1 and 5, in order to improve the reliability of the action of the micro switch 41, the weighing assembly 2 further includes a baffle 24, the upper end of the baffle 24 is installed on the upper portion of the front end face of the hook base 211 through a horizontal rotating shaft 25, a hook body avoiding opening 241 is provided at the lower end of the baffle 24, the baffle 24 can rotate in a vertical plane around the horizontal rotating shaft 25, and the lower side face of the baffle 24 is in contact with the elastic sheet of the micro switch 41. When the urine collection bag 3 is hooked to the hook body 212, the hook of the urine collection bag 3 touches the stopper 24, and the stopper 24 pushes the spring of the microswitch 41 to operate. Therefore, the situation that the identification information is inaccurate due to the fact that the hook of the urine collection bag 3 deflects and does not touch the elastic sheet of the microswitch 41 when being hung can be avoided.

The weighing sensor 22 in the invention adopts a low-temperature drift coefficient sensor, so that the influence of the ambient temperature on the urine volume monitoring result can be reduced. The weighing sensor 22 is made of stainless steel or aluminum alloy, and the deformation is small, so that the weighing sensor 22 is prevented from being deformed due to stress impact when the urine collection bag 3 is hung. Further, in order to reduce the influence of the monitoring result of the ambient humidity symmetrical sensor 22, the measuring circuit of the urine volume monitoring device of the present invention performs a three-proofing process, or seals a humidity-sensitive device to isolate the moisture in the environment.

Referring to fig. 2 and 3, the urine volume monitoring device of the present invention further comprises a urine drainage control unit 9, wherein one end of the urine drainage control unit 9 is connected to the urine inlet of the urine collection bag 3 through a first conduit 31, and the other end of the urine monitoring unit 9 is connected to the urinary catheter through a second conduit 32. The urine drainage control unit 9 is a cuboid structure which is small in structure and convenient for a human hand to hold.

A radio frequency card (not shown in the figure) is arranged in the urine drainage control unit 9, and the radio frequency card is commonly called an electronic tag. The radio frequency card records important information such as the name, age, contact information, medical history and the like of the patient. When the urine drainage control unit 9 is close to the main control unit 5 in the housing 1, the main control unit 5 can read the information on the radio frequency card and can display the information on the display 516. Optionally, the radio frequency card further records the service life and the starting time of the urine collection bag 3, when the urine drainage control unit 9 is close to the main control unit 5, the main control unit 5 can read the relevant data of the service life and the starting time of the urine collection bag 3 on the radio frequency card and display the data on the display 516, and when the urine collection bag 3 reaches the service life, the main control unit 5 will prompt to change the consumable.

Specifically, urine drainage control unit 9 includes main casing body 91, and this main casing body 91 is the cuboid shape, is moulded plastics by medical grade plastics material and is made, and its inside monitoring control chamber that has the confession urine and pass through, and 9 one end of urine drainage control unit is equipped with the liquid inlet 92 that can communicate with second pipe 32, and the other end of urine drainage control unit 9 is equipped with the liquid outlet 93 with first pipe 31 intercommunication. A control valve (not shown) and a pressure sensing part (not shown) are arranged in the control cavity of the urine drainage control unit 9. The control valve is used for controlling the on-off of urine, and the pressure sensing component is used for monitoring the pressure of the urine in real time. The control valve is located downstream of the pressure sensing component. By setting the control valve, the urination operation with timing or constant pressure can be realized through artificial operation. For some patients with urination disorder, the urinary bladder expansion and contraction function is slowly degraded due to the continuous conduction of urine in the urinary bladder of the patient through the catheter for a long time, so that a device for changing the urinary bladder pressure to guide urine is needed to help the patient to train the urination function. Therefore, by providing the pressure sensing part and the control valve, it is possible to continuously monitor the pressure of urine by the pressure sensing part with the control valve closed, and open the control valve after the monitored pressure of urine reaches a predetermined value, thereby achieving constant pressure urination, or achieve regular urination by setting the control valve to open and close at predetermined time intervals. The specific structure and principle of the inside of the urine drainage control unit 9, the specific structure of the pressure sensing component and the control valve can be referred to the published chinese patent with publication number CN 106139264a, and are not described herein again.
