Drawings
FIG. 1 is a schematic diagram of a detecting device of a urine flow rate meter according to a preferred embodiment of the invention.
Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 1, the detecting device of the urine flow rate meter of the present embodiment includes a water inlet 1, a water outlet 2, a first pipe, a first solenoid valve 6, and a power supply 4. Two ends of a first pipeline are respectively connected with the water inlet 1 and the water outlet 2, a first pump 5 and a first electromagnetic valve 6 are arranged on the first pipeline, and the first electromagnetic valve 6 is electrically connected with the first time relay 3. The power supply 4 is used for supplying power to the first pump 5 to turn on the first pump 5 and for supplying power to the first time relay 3 to turn on the first solenoid valve 6. When the first pump 5 and the first solenoid valve 6 are simultaneously opened, the liquid flowing in from the water inlet 1 flows out from the water outlet 2 through the first pipe and flows into the urine flow rate meter 8. Wherein the water inlet 1 is typically connected to a mains water system 7, so that the liquid is also mains water.
In urology diagnosis, the urometer needs to measure three indexes of time, weight and flow rate of urine flow, and the following illustrates the principle of detecting urometer measurement by using the testing device of the present embodiment: before testing, the uroflow meter is started, the power supply is started, the first pump and the first time relay are powered by the power supply, the timer (usable timer) is started, the power supply is turned off after a period of time (generally 10 s) is continued, and the timer is ended. During the power supply process of the power supply, the first pipeline is conducted, and tap water flows into the measuring cup 81 of the urine flow rate meter 8 from the water outlet. And after the power supply is finished, weighing the liquid in the measuring cup 81 to obtain the weight of 150g, and calculating the flow rate of the liquid to be 15g/s according to the weight of the liquid and the timing time (namely the power supply time of the power supply). If the urine flow time, the urine volume and the urine flow rate digitally printed by the urine flow rate meter are respectively 10s, 150g and 15g/s (a little error is allowed to exist), the unit error for measuring the three indexes in the urine flow rate meter accords with the technical requirements. If the difference between one index and the measured value is larger in digital display printing of the urine flow rate meter, the error of the detection unit is out of limit, and the urine flow rate meter needs to be calibrated. Therefore, the detection device of the embodiment can accurately detect whether the urine flow rate meter is qualified or not, and diagnosis errors caused by deviation of the urine flow rate meter by doctors are avoided, so that medical accidents are reduced. In addition, the detection device of the embodiment can also detect whether the two-second urine flow index measured by the urine flow rate meter is accurate, and the detection method is the same as above, and will not be described here again.

And (5) detecting urine volume indexes. The controller acquires the urine volume measured by the urine flow rate meter and judges whether the difference value between the weight and the urine volume is within a second preset range; if the difference value between the weight and the urine volume meets the technical requirement, generating a detection result which is that the urine volume of the urine flow rate meter is detected to be qualified; if not, namely the difference value of the weight and the urine volume does not meet the technical requirements, the generated detection result is that the urine volume of the urine flow rate meter is unqualified.
And detecting a urine flow rate index. The controller is also used for calculating the flow rate of the liquid according to the weight and the power supply time length, acquiring the urine flow rate measured by the urine flow rate meter and judging whether the difference value between the flow rate and the urine flow rate is within a third preset range; if the difference value between the flow rate and the urine flow rate meets the technical requirement, generating a detection result which is that the urine flow rate of the urine flow rate meter is qualified; if not, namely the difference value of the flow rate and the urine flow rate does not meet the technical requirement, the generated detection result is that the urine flow rate of the urine flow rate meter is unqualified.
