Embodiment Construction

[0021] Such as Figure 1-Figure 4 As shown, the urine conductivity dynamic monitoring device of the present invention includes a computer, an excitation module, a drive module, a measurement module, a signal acquisition and conditioning module, and several electrodes. Among them, the excitation module mainly produces a constant current sine wave output signal, the frequency is in the range of 10-100kHz, the amplitude is 1-5mA, and the frequency and amplitude are adjustable. The drive module and the measurement module are mainly composed of multiple switches, which control the selection of a pair of excitation electrodes and a pair of measurement electrodes through computer instructions. After the signal conditioning module in the signal acquisition and conditioning module receives the signal output by the measurement module, it amplifies the signal and performs DC conversion on the signal, and the obtained DC signal is sent to the acquisition module in the signal acquisition an...

Abstract

The invention provides a urine electrical conductivity dynamic monitoring device and method. The urine electrical conductivity dynamic monitoring device comprises a computer, an exciting module, a drive module, a measurement module, a signal acquisition and conditioning module and a plurality of electrodes. The exciting module mainly generates constant-current sine-wave output signals, the drive module and the measurement module are mainly formed by multi-way switches which control selection of exciting electrode couples and measurement electrode couples through commands of the computer, the signal acquisition and conditioning module amplifies signals output by the measurement module and carries out direct-current conversion on the signals to obtain direct-current signals which are sent to a collection module, and the collection module carries out analog and digital conversion on the input signals and outputs digital signals to the computer. The urine electrical conductivity dynamic monitoring device displays the change of urine electrical conductivity in a two-dimensional image mode, and achieves continuous dynamic monitoring of the urine electrical conductivity.

Description

Technical field [0001] The invention relates to a device for dynamically monitoring the conductivity of urine and a method for dynamically monitoring the conductivity of urine by using the device. Background technique [0002] According to clinical observations and experiments, the conductivity of urine can reflect the concentration and dilution function of the kidney. Some kidney diseases (such as kidney failure, kidney stones, etc.) will cause changes in the function of kidney concentration and dilution; for certain kidney diseases (such as water and sodium retention caused by elderly heart failure) during the treatment process, doctors need to continuously monitor urine conductivity In order to control the dosage to achieve a better therapeutic effect. In addition, patients with urinary incontinence, spinal cord injury and other causes of lack of urination need various auxiliary methods to help urinate. Under the above background, it is necessary to monitor the conductivity ...
