Description

The utility model relates to medical equipment and is intended to test a simple sensorimotor reaction.

It is known to measure the reaction rate using a falling line. During testing, the researcher releases without warning in an upright position a ruler 50 cm long with a zero mark at the level of the index finger and thumb of the leading hand, spaced 3-5 cm apart. The place of capture of the falling ruler (in cm) is a quantitative result of evaluating the reaction rate. The more centimeters in the place of capture of the line, the lower the reaction rate [Kuznetsova MN, Polyakov SD, Podgornova NS, Sobolev AM Testing the level of physical health of preschool children in order to correct physical fitness work // Pediatric Pharmacology. 2011. No5. S. 66-69.].

The diagnostic gravity chronoreflexometer relates to medical equipment and is intended to measure the time of a simple sensory-motor reaction of a person [Patent 2199950 RF, IPC A61B 5/16. Diagnostic gravitational chronoreflexometer / Zimin A.G., Nikiforov V.G. - No. 2001101132/14, declared 01/16/2001; publ. 03/10/2003; Bull. No. 7.].

Shaper 7 is designed to generate pulses of random duration and can be performed, for example, according to the patent [Patent 2261527 of the Russian Federation, IPC H03K 5/156, H03K / 84. Pulse generator of random duration / Chulkov V.A. - No. 2004107717/09; declared 03/15/2004; publ. 09/27/2005.]

Single vibrators can be performed, for example, using the K155AG1 chip, which can be triggered both on the leading and trailing edges of the incoming pulses, according to the diagram in Fig. 4.20, S. 216 [Calculation of the elements of digital devices: Textbook. allowance / L.N. Presnukhin, N.V. Vorobiev, A.A. Shishkevich; Ed. L.N. Presnukhina. 2nd ed., Revised. and add. M.: Higher School, 1991.526 p.].

The amplifier 9 is designed to generate the current required for the source 23 of the light signals.

The 15-color switch “Color” in one direction with three positions (“Red”, “Green” and “Blue”) is intended for switching power to one of the three terminals of the light signal source 23.

The source of 23 light signals is designed to create light signals of red, green or blue and can be performed, for example, on a full-color LED BL-L515RGBW-CA.

The remaining functional units of the structural diagram of the claimed device are well known.

The device operates as follows. The switch 15 "Color" is set to one of the positions depending on the desired color of the light signals. When the power is turned on, the triggers 4, 11 and 16, the counters 10 and 20 and the divider 19 are reset to zero, the voltage corresponding to the average value of the duration of the output pulses equal to 2 seconds is set at the input of the first reference voltage of the driver 7, and the voltage corresponding to the deviation is at the input of the second reference voltage output pulse duration of 1 second (circuits not shown). At the output of element 2 OR NOT 5, the level of the logical unit is set, gate 6 opens with a signal from the output of the second 11 RS-trigger, the level of the logical unit is set at the output of gate 6, the generator 14 generates pulses with a frequency of 1 kHz.

The test subject briefly presses the ready button 1, the binary code 1010 (circuits not shown) corresponding to the number 5 in the decimal code is recorded in counter 10, a short pulse is generated at the output of trigger 4 (Fig. 2a), which is inverted by element 5 and through the first 6 open valve arrives at the shaper 7 (Fig. 2B). At the beginning of the pulse of negative polarity, the driver 7 generates an output pulse of random duration in the range from 1 to 3 seconds (Fig. 2B).

According to the decay of the pulse from the output of the shaper 7, the one-shot 8 generates a pulse lasting 20 ms (Fig. 2d), which through the amplifier 9 and switch 15 is supplied to the source 22, which generates a light signal of a given color.

At the same time, the pulse from the output of the one-shot 8 is fed to the S-input of the trigger 16 and sets it to unity (Fig. 2e). The signal from the output of the trigger 16 opens the valve 18, pulses with a frequency of 1 kHz from the output of the generator 14 through the open valve 18 are fed to the divider 19 (Fig. 2E). The pulses from the output of the divider 19 are supplied to the counter 20, the counting result by the converter 21 is converted to a decimal code and displayed on the digital indicators 22. At the same time, the pulse from the output of the one-shot 8 is fed to the counting input of the counter 10 and increases its content by one.

The test person, when the light signal source 23 is turned on, after some latent time presses the “Reaction” button 3 (Fig. 2g), the logic unit level is sent to the R-input of trigger 16, the trigger 16 is reset (Fig. 2d), valve 18 is closed, the input pulses the divider 19 is terminated (Fig. 2E).

At the same time, the logic zero level from the output of the trigger 16 is fed to the input of a single-shot 17, which at the beginning of a pulse of negative polarity produces a short pulse (Fig. 2h). The pulse from the output of the one-shot 17 is inverted by the element 2 OR NOT 5 and through the open first 6 valve is supplied to the former 7, which generates the next pulse of random duration at the output (Fig. 2c).

Further, the testing process continues in a similar way until the tenth light signal of a given color is presented to the test person, at which the pulse from the output of the single-vibrator 8 enters the counting input of the counter 10 and sets the logical zero level at the inverse S input of the second 11 RS-flip-flop. At the output of the second 11 RS-flip-flop, the level of the logical unit is set, which closes the first 6 gate. At the same time, the level of logical zero from the transfer output when adding the counter 10 goes to the input of the second 12 gate and opens it.

The test subject, when the tenth light signal is turned on, after some latent time presses the “Reaction” button 3, the logic unit level is sent to the R-input of trigger 16, the RS-trigger 16 is reset, the valve 18 is closed, the pulses to the input of the divider 19 are stopped. Digital indicators 22 display the arithmetic mean value of ten sensorimotor reactions to light signals of a given color presented at random in the range from 1 to 3 seconds.

At the same time, the logic zero level from the output of the RS flip-flop 16 enters through the open second 12 valve to the end indicator 13 of the test and turns it on.

After recording the test results, the reset button 2 is pressed, the second 11 RS-trigger is reset, the first 6 valve closes, the device is set to its initial state (circuits not shown).
