Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] like figure 1 As shown, in the method for detecting changes in urine parameters provided by the embodiment of the present invention, after the urine parameter change detection system starts to work, the urine parameter change detection is performed according to the following steps:

[0035] Collection: After the human body starts to urinate, the urine passes through the urinary tube 6, passes through the pipe between the two driving coils 5 and 7, and forms a urine drop 9 on th...

Abstract

The invention discloses a method and system for detecting the parameter change of urine. The detection method comprises the following steps: signal acquisition, preprocessing, classification, calculation of the urinary flow rate and the urine volume of a first class (no urine drop falling) signal, urine drop counting and urine density calculation of a second class (urine drop falling) signal, and result output. The detection system includes a urine funnel arranged on a urinary catheter, two driving coils arranged outside the urinary catheter and an induction electromotive force electrode, urine flows and cuts the driving coils to generate induction electromotive force which drives a solenoid arranged outside the urine funnel, the magnetic field intensity of the solenoid is detected and amplified by a magnetic tunnel junction, the amplified magnetic field intensity is acquired and is input to a computer, and the change of the urine flow amount, the urine volume, the urine density and other urine parameters is detected, output and displayed. A set of the integrated detection system is adopted, output of a magnetic tunnel junction sensor is used, and the changes of multiple urine parameters are simultaneously detected, so the method and the system have the advantages of simple structure, low cost and reliable measurement result.

Description

technical field [0001] The invention belongs to the field of medical monitoring, in particular to a method and system for detecting changes in urine parameters. Background technique [0002] Urine in the human body contains important information on human health. Monitoring urine parameters can play an important role in clinical diagnosis, judgment of curative effect and prognosis. [0003] General urine routine analysis can analyze the physical parameters and chemical components in the urine by collecting urine samples. These analyzes can obtain the urine parameters at the time of sampling, but cannot continuously analyze the parameters of urine in a long period of time. In clinical medicine, especially during surgery, it is necessary to monitor the urine parameters of the human body. Urine flow rate reflects the volume of urine excreted by the human body per unit time, urine output is the total volume of urine excreted by the human body within a monitoring period, and urin...
