As a modified specific embodiment, the flow rate detector 221 includes a pressure sensing crystal 2211 and a transmission crystal 2212, the transmission crystal 2212 is fixed on the inner wall of the tube 21, the pressure sensing crystal 2211 is fixed on the side of the transmission crystal 2212 opposite to the inner wall of the tube 21, the pressure sensing crystal 2211 has a pressure sensing surface, the pressure sensing surface is arranged on the side of the pressure sensing crystal 2211 opposite to the transmission crystal 2212, the pressure sensing crystal 2211 is coupled with the transmission crystal 2212 to sense the pressure and output a pressure signal to the transmission crystal 2212, the transmission crystal 2212 is connected with a wireless transmission board 223 to transmit the pressure signal to the analysis server 12 for analysis and calculation by the analysis server 12, and the flow rate value is obtained because if the urine is provided with an obstruction in the flow path during the flow, the pressure exerted on the obstruction by the urine is proportional to the flow rate, therefore, feel the mode that the urine applied to the pressure on the response face through pressure sensing crystal 2211, so just can be fine the realization detect the effect of urine velocity of flow, simultaneously through pressure sensing crystal 2211 and transmission crystal 2212's setting, alright effectual increase body 21's density, and then realized that the development that two J pipes can be better has imaged.
As an improved specific embodiment, the concentration detector 222 includes a light emitting lamp 4 and a light sensor 5 disposed on the pressure sensing surface of the pressure sensing crystal 2211, and the light sensor 5 is coupled to the transmission crystal 2212 and is configured to output a light sensing signal to the transmission crystal 2212 and further to be transmitted to the analysis server 12 through the transmission crystal 2212, since urine is in a liquid state, the urine has a certain light transmittance for light, especially when the urine concentration is higher, the light transmittance of urine is lower, and the corresponding reflectivity is higher, so that in this embodiment, the light emitting lamp 4 is adopted to emit light with a certain brightness, and then the urine concentration is detected by how much urine is reflected, the whole structure is simple and easy to implement, wherein the light sensor 5 of this embodiment may adopt a photoresistor, and the change of the output resistance is utilized to reflect the light of urine, further reflecting the concentration of urine.
In summary, the renal urine drainage system of the present embodiment detects three parameters, namely, the flow rate, the concentration and the composition of urine, by means of the cooperation between the detection device 22 and the urine composition analysis device 11 in the double J-tube 2 and the external analysis server 12, so as to monitor the ureter and the kidney of the patient.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
