Description

 The invention relates to sports, medicine, as well as to any other related to the registration of temperature.

 Known electronic thermometers, which have a high complexity of circuitry, small temperature recording limits, low measurement accuracy, industrial reflectometers IPP-01, EMR, have large dimensions, high cost, high power consumption.

 The simplest and closest analogue adopted for the prototype is an IC reflectometer, which contains two pulse generators, a trigger, two keys, a coincidence element, a pulse counter, an indication unit, a Reset element, two switches, a third key. The device registers the test subject's response to stimuli: sound, light, which is a test of the reaction's BP-time. The reflexometer has several disadvantages: the frequency of the first generator is not standard, there is no stabilizer, which reduces the accuracy of the readings, there is no possibility of registering temperature.

 The objective of the invention is to eliminate these disadvantages and expand the scope of its application.

 The drawing shows a structural diagram of a reflexometer with temperature recording.

 The reflexometer contains two pulse generators 1 and 2, trigger 3, five keys 4, 5, 12, 15, 19, a coincidence element 6, a pulse counter 7, an indication unit 8, a reset element 9, five switches 10, 11, 16, 17, 18, time relay 13 indicator 14, sensor 20, calibration element 21, frequency controller 22, voltage stabilizer 23, converter 24, temperature sensor 25, sixth switch 26.

 The reflexometer works as follows: with the switch 26 turned on, the output of the first generator 1 is turned off from the input of the coincidence element 6, and the output of the converter 24 is connected to its input.

 The key 19 is started, through its closed contact from the output of the voltage stabilizer 23, the voltage is supplied to the input of the time relay 13, and a low potential appears on its output, which is fed through the normally-closed contact of the key 12 to the first input of trigger 3, translating its output into a single position, goes to the first input of element 6, coincidence, opening its second input. From the first output of the generator 1 through a normally closed contact of the switch 26, through the second input of the coincidence element 6, the pulses begin to arrive at the input of the pulse counter 7 and the digital indication unit 8. After 1 second, a high-level potential appears at the output of the time relay 13, which is fed through the normally closed contact of the key 12 to the first input of trigger 3, translating its output to the zero state and goes to the first input of coincidence element 6 closes its input 2. generator 1 will stop the flow of pulses to the counter 7 pulses and digital display. For a period of time equal to 1 s from the generator 1, 1000 pulses will arrive at the digital display, which will correspond to the value of the calibration element 21 100 kOhm.

 Thus, the “Reflexometer” is calibrated if the indicator differs from the calibration value by more than 1% and is easily calibrated by the value of the voltage stabilizer 23, to record the temperature indicator, turn on the switch 26, its contacts connect the output of the converter 24 to the input 2 of the coincidence element 6. The switches 18, 16 are in the initial position. The temperature sensor 25 is located on the object, after 3-4 seconds, the key 19 is started (everything else according to the description of the reflexometer for calibration).

 To register the BP reaction time index, the switches 26, 16 are in the initial position. We turn on the switch 18, which with its contacts turns on the generator 2, then the second output of the switch 11 is connected to the input of the voltage stabilizer 23. In the initial position, from the output of the time relay 13, a high level potential is supplied through the closed contact of the key 12 to the first input of trigger 3, pressing the key of the key 12 opens its contact, a low potential appears at the first input of trigger 3, but the logic state remains at its output zero, only when the first pulse arrives from the output of generator 2, trigger 3 fires, logic 1 appears on its output, the second input of coincidence element 6 opens, pulses from the first output of generator 1 through the second input coincidence point 6 is sent to the first input of the pulse counter 7, to the output of the key 4 and the indicating unit 8, when a sound appears, the subject opens his finger from the key of the key 12, at the first output of trigger 3, a high potential from the time relay 13 appears through the closed contact of the key 12, the trigger 3 closes the second input of the coincidence element 6 with its output, the counting and the sound stimulus are stopped, information on the reaction duration appears from the display unit 8, from the appearance of the signal to the action of detaching the finger from the key key 12.
