摘要：
The invention relates to means intended for biomedical studies on laboratory animals, in particular for measuring the heart rate, breathing rate and locomotor activity of the animals. The stand comprises a cage for laboratory animals, measuring platform with sensors monitoring the animals vital parameters and acquisition module, data processing and transmission. To the inputs of the module connected to the sensor output. The measuring platform and placed under the cage comprises at least two sensors, which are symmetrically arranged along the bottom of the cage. Each sensor comprises a microwave generator oscillation power divider, a signal mixer sensitive element in the form of a coplanar stripline transmission signal forming the working channel, an asymmetric stripline transmission line signal forming the reference channel, and a dielectric substrate. Working and reference channels are connected between the outputs of the power divider and the mixer input signal. On one surface of the substrate coated conductive layer and a grounded circuit path working channel. On the opposite surface of the substrate coated printing path reference channel. The surface of the substrate with an electrically conductive ground plane and the working channel circuit path faces the cell. The attenuator is connected between the output of the power divider and the input of the coplanar line. Module collection, processing and transmitting data comprises serially coupled amplifier signal inputs are connected to which sensor outputs a low-pass filter, an analog-digital signal converter and a microcontroller. The composition of the microcontroller includes a processor, a programmable read only memory and random access memory. The personal computer is connected to the output module via the data transmission line. With the stand is provided a non-contact monitoring of physiological parameters of laboratory animal waste, comprising the simultaneous measurement of heart rate, respiration rate an
