The fourth and fifth inputs 1.4 and 1.5 are respectively connected to the Poll and Reset switches. Sixth

the input 16 is connected to the sensor 7 by exceeding the required pressing force.

Dummy simulator works as follows.

Before carrying out the revival, the dummy 1 and the electronic unit 8 are prepared for operation by filling with water through the holes in the nasal passages of the tank and pressing the Reset button on the control panel 0 of the electronic unit 8.

The process of practicing resuscitation skills includes the following steps.

1, Pressing the Work button.

2, Drainage position - phantom turn- 5 turn face down and lift

body so that the head was below. At the same time water begins to leave the nasal passages. After complete removal of water immediately proceed to the next step.

0 3. The introduction of air - a phantom on the back, the head is thrown back, the output of the lower jaw. An open S-tube is inserted into the open mouth (head kept upturned) so that the insertion end

5 went down to the trachea,

4, Massage of the heart and artificial respiration — the student to the left of the phantom with the palms of both hands exerts a smooth pressure on the sternum to capture the area

0 hearts (6-7 mezhber). The applied force is adjusted so that the deflection of the sternum does not exceed 2-3 cm. After five rhythmic taps, one breath follows.

The program of work on the simulator provides for the implementation of sixteen cycles (5 taps and 1 breath in each). The correctness of their implementation is recorded on the scoreboard of the electronic unit of the simulator. With each correctly executed tact, the bone of the illumination of the phantom head increases and after the sixteenth cycle the eyes open.

If the required effort is exceeded - the sinking of the sternum exceeds the permissible value - the sensor 7 is activated, which is signaled by the alarm 20 and the next massage is not counted. The animation process is recorded in

0 electronic unit 8 as follows. After removing water from the reservoir, the sensor 4 is triggered and the massage and time counters 23 and the time 30 trigger the R-inputs. The time counter 30 starts counting

5 pulses with a frequency of 10 Hz, arriving at its C-output from the additional output of the generator 27 through the first input of the 2I-2ILE-NOT 28 circuit. The states of the most significant bits of the time counter are 30, starting with a weight of 1 s and ending with units of minutes are indicated by the time indication circuit , allowing the learner to be time oriented. At the same time, the outputs of time counter 30 serve as the address bits of memory block 22. With the massage forces applied by the trainee to the dummy's chest that are within the specified limits, the massage counter 23 counts the number of actuations of the sensor 6, while upon reaching the programmed number of massages, the matching circuit 26 is triggered, allowing the breath counters to change the state of 32 breaths by counting the input through the third circuit 2I — NO 31. When there is no activation of the sensor 5 (no breath or a weak breath), the state of the counter 32 does not change. With each sufficiently strong inhale, a pulse is formed through the first 2I-NOT 24 circuit. Recording of memory block 22 records the states of counters 23 and 32 at counter 30. With an increase in the signal from counter 32, the duration of pulses generated by LUHW 33 increases and Accordingly, the luminance of the illuminating lamp 3 of the face mask, connected via amplifiers 34 and 35 to the PWM output 33. When the unit appears at the additional output of the counter 32 through the amplifier 35, the electromagnet 3 is activated, causing the dummy to open its eyes. The revitalization process is over. If it is necessary to restore its stroke, press the Poll button, releasing the Job button. The pulses from the generator 27 (with a frequency higher than in the case of Work) pass through the third input of the 2I-2OR-NOT circuit, causing a sequential reading of the contents of memory block 22 through register 21 to a state indication circuit is simultaneously indicated an accelerated time by a time indication circuit. The polling process can be repeated many times.

When the student exceeds the required pressure, the alarm 20 triggers an excessive force (audible alarm of sensor 7), and the next massage with the massage counter 23 is not counted due to the first matching circuit 25 .v
