Description

The device relates to the field of physical education and sports, forensics, medicine and is intended for rapid measurement of the psychophysical data of a person.

It is known "Device for diverting bioelectric potentials from plant organisms" (SU 1738264 A1, A 61 B 5/04, 06/07/1992). This device is applicable only to plants.

It is known "Device for measuring the active and reactive components of the impedance of biological tissues" (SU 1759402 A 1, A 61 B 5/05, 09/07/1992). This device is applicable for express diagnostics, but it is difficult to manufacture and not applicable in the field.

The known "Device for assessing the state of biological objects" (SU 1717102 A1, A 61 B 5/00, 03/07/1992). It is applicable to assess the psychophysiological state of humans and animals, including in the field. But this device uses color indication, which does not provide the desired measurement accuracy.

In addition, the disadvantage of these devices is that they measure only one parameter of psychophysical data, which reduces the reliability of the results and they are not used in the field of physical education and sports, criminalistics.

Closest to the proposed is a device that measures the psychophysical data of a person: skin-galvanic reaction, tremor of the finger, pulse rate, blood pressure, parameters of upper and lower respiration.

It is called a "lie detector" (Ekman P. The Psychology of Lies. St. Petersburg: Peter, 2001. S.134-144). It is manufactured commercially under various

names, for example, a computer polygraph “EPOS-5”, made at the Research Institute of Special Equipment of the Ministry of Internal Affairs of Russia ZPO “EPOS Group”.

The disadvantages of this device are the complexity of the entire structure, large dimensions, the inability to use it in the field, a very high price.

The objective of the proposed technical solution is to create a simple, cheap, small-sized portable device with which you can even carry out rapid measurements of the psychophysical data of a person even in the field during the training of athletes and conduct sporting events, identify false testimonies during polls, establish the difference between the psychophysical human condition before and after the treatment procedure.

To solve this problem, a device is proposed, which consists of a rectangular case 1, on which are fixed: an electronic display 2, a sleeve 3 for a button 4, a switch 5. An electronic unit 6 and a power supply 7 are installed in the case, a pressure force sensor 8 is located under the button, sensing the force of the spring 9, fixed on the end of the button 4. To the same end on the lever 10 is fixed a frequency and amplitude sensor for tremor of the finger 11. Two strips are made on the upper surface of the button: copper 12 and zinc 13, between which two ele ctrode made of metal 14 and 15. The case 1 also has a time relay, designed to record the time of the measurement. See figure 1 is a top view of the proposed device, figure 2 is a side view (the device is shown in section).

The device operates as follows.

Before training the athlete, the device is installed on the table, or on any plane, turn it on with switch 5 and offer the athlete, with his arm extended forward, press the forefinger

finger 4 device button for 2-3 seconds. The measurement time is set using a time relay, which after measurement disables the measurement mode. When pressed, button 4 compresses the spring 9, which in turn transfers pressure to the pressure force sensor 8, while the tremor is transmitted to the frequency and amplitude sensor of the tremor. In this case, under the action of the potogyr substance of the skin of the finger between the copper and zinc strips, a current arises, depending on the content of certain chemical components of the potogy substance. When the finger skin contacts the electrodes 14 and 15, changes occur in the input circuits of the electronic unit 6. The signals from the sensors are sent to the electronic unit 6 for processing and the measurement results are transferred under the serial number to the electronic display 2 in the following order: tremor frequency, tremor amplitude, pressure force, skin resistance, current generated by contact between the skin of a finger and strips of copper and zinc, and the results disappear from the display only after turning off the device.

After a certain physical load, the measurements are repeated and compared with the primary ones. The level of difference between the values allows us to judge the permissibility of the load.

The proposed device is compact, allows for rapid measurement of psychophysical data of a person even in the field, is easily available for production.
