FIG. 2 is a cross-sectional view of a main part showing the internal structure of the human body model 10, which has a simulated chest structure 20 that can perform both exhalation blowing training and cardiac muscle surge training.

This imitation chest structure 20 includes a lung plate 25, a lung bag 3
0, blowing pipe 31, discharge pipe 37, exhalation slider 4
1, exhalation blowing confirmation switch 43, exhalation blowing confirmation sound signal device 52A, cardiac muscle surge hand position confirmation switch 60, cardiac muscle surge hand position confirmation sound signal device 52B, cardiac muscle surge compression confirmation switch 47,
This includes each component of the cardiac muscle compression confirmation sound signal device 52C. Next, the outline of each part will be briefly explained.

The lung plate 25 is provided between the back plate 14 and the chest plate 15 and urged toward the front of the chest plate by an elastic member 21.

The lung bag 30 is placed between the chest plate 15 and the lung plate 25.

The blowing pipe 31 connects the mouth portion 11a and nose portion 11b of the simulated head 11 to the lung bag 30 via a check valve 35.

The exhaust pipe 37 exhausts the air inside the lung bag 30 to the outside of the human body.

Further, as shown in FIGS. 3, 4, and 5, the exhalation slider 41 includes a lung plate 25 and a lung bag 30 in a slider box 40 fixed to the back side of the lung plate 25. It is provided so as to penetrate and come into contact with the back surface of the chest plate 15 so as to be able to move back and forth integrally with the chest plate (see FIG. 5).

The exhalation blow confirmation switch 43 is activated by advancing the exhalation slider 41 to a predetermined position.

Further, the exhaled air blowing confirmation sound signal device 52A generates a sound when the exhaled air confirmation switch is operated.

In addition, cardiac pine surge hand position confirmation switch 6
0 is provided at a predetermined position on the surface of the chest plate as shown in FIG.

The cardiac muscle hand position confirmation sound signal device 53B generates a sound when the hand position confirmation switch 60 is operated.

The cardiac muscle compression confirmation switch 47 detects the depression of the lung plate 25 to a predetermined position.

The cardiac muscle compression confirmation sound signal device 52C generates a sound when the compression confirmation switch 47 is operated.

Next, the structure of the human body model for resuscitation training according to the present invention will be specifically explained in detail with respect to each training device.

First, the exhalation blowing training device of the present invention will be described. As can be clearly understood from FIG. be done. This blowing pipe 31 is preferably a flexible bellows-shaped pipe. The blow pipe 31 is the check valve 3
5 and a connector 36 to the lung bag 30 placed on the lung plate 25.

On the other hand, a discharge pipe 37 is connected to the check valve 35, so that the air inside the lung bag 30 can be discharged from the discharge port 38 to the outside of the human body. In other words, the air blown from the mouth 11a or the nose 11b is transferred from the blowing pipe 31 to the lung bag 30, and from the lung bag 30 to the lung bag 30.
The air discharged from the exhaust port 3 passes through the exhaust pipe 37.
8 is controlled in one direction by a check valve 35.

As can be better understood from FIGS. 3 and 5, a slider switch box 40 is fixed to the back surface of the lung plate 25.
An exhalation slider 41 is elastically attached therein by a spring 42 so as to pass through the notch 26 of the lung plate 25 and have an elastic force toward the chest plate 15 side. Further, as shown in FIG.
is formed, and the tip of the exhalation slider 41 is configured to pass through the hole 39 of the lung bag 30 and come into direct contact with the back surface of the chest plate 15.

Therefore, when air is blown into the lung bag 30 and it expands, the lung bag 30 pushes up the chest plate 15 and bulges out, as shown in FIG. The exhalation slider 41 is attached to the chest plate 1
5, it moves forward (raises) due to the elastic force of the spring 42 as the chest plate 15 rises.

When the exhalation slider 41 moves forward to a predetermined position, an exhalation confirmation switch 43 consisting of a limit switch installed in the slider switch box 40 is turned on.

When the exhaled air blowing confirmation switch 43 is operated, the exhaled air blowing confirmation sound signal device 52A generates a sound, for example, an electronic sound such as "horo horo horo...". This sound signal is designed to be activated when approximately 1000 c.c. or more of air is blown into the lung bag 30, which is the appropriate amount of expiratory air blown into the lung bag 30.

In addition, in FIG. 3, the reference numeral 27 is a notch for connecting the lung bag 30 and the check valve connector 36, 28 is an air relief groove for the elastic member, and the reference numeral 36a in FIG. 4 is a check valve connector of the lung bag 30. 36 are respectively shown.

Next, the cardiac muscle surge training device will be explained. The important points in cardiopulmonary surge training are checking the pressure position, that is, the hand position, the compression force,
There are three points regarding rhythm. In this invention, a hand position confirmation switch is activated by compression on a predetermined position of the chest and generates a first sound signal, and a compression confirmation switch is activated by a predetermined compression force and generates a second sound signal. including, and optionally alone,
Alternatively, a pace sound such as a metronome sound can be generated as the first sound signal.

That is, as shown in FIG. 2 and described above, the simulated chest structure 20 of the human body model 10 includes the back plate part 1.
The chest plate 15 is supported by the elastic support member 21 so as to be elastically movable up and down with a predetermined pressure. This resilient support member 21 is shown in FIG. 3 or 6.
As is clear from the figure, the base 22 on the back plate 14 side
The outer cylinder 23a fixedly attached to the lung plate 25 on the chest plate 15 side
It is composed of an inner cylinder 23b and a spring 24, which are fixed to the inner cylinder 23b and a spring 24, and is applied to a predetermined depth (about 1/4 of the chest thickness, about 4.5 cm) by a predetermined pressure (about 45 kg), which is almost the same as that applied to the human body. Its repulsion force is set so that it sinks.

In addition, in order to confirm the hand position of Matusage, a hand position confirmation switch 60 consisting of a thin plate-shaped micro two-point switch as shown in FIG. be done. This hand position confirmation switch 60 cannot be turned on unless two switch buttons 61 and 62 are pressed at the same time, and it is designed around the outer periphery of the button so that it will not be activated unless a pressure of more than a predetermined level is applied to the chest. A protrusion 63 is provided in a protruding manner.

By the operation of this hand position confirmation switch 60, the hand position confirmation sound signal device 5 of the sound signal device 50 in FIG.
2B pronounces. In this case, the sound signal is preferably a pace sound at constant intervals (for example, 60 times per minute), such as a metronome sound, in order to learn the pine surge pace. In addition, if this sound signal is a pace sound, the hand position confirmation switch 6 should be set so that the pace sound can be heard prior to pine surge training.
It is desirable to incorporate a circuit that operates separately from the 0.

Furthermore, the vertical movement of the chest plate 15 during the pine surge is sensed by the compression confirmation switch 47, which is a limit switch in the slider box 40, as shown in FIG.

Then, by operating the compression confirmation switch 47, a second sound signal different from the first sound signal produced by the hand position confirmation switch 60 is generated.
That is, as shown in FIG. 6, the compression slider 45 is attached to the slider box 40 with elastic force applied to the back plate portion 14 side by a spring 46, and the spring 2 of the elastic support member is attached to the slider box 40.
When the chest plate 15 is pressed with a predetermined compression force against the elastic force of 4, the slider box 40 fixed to the lung plate 25 at the lower part of the chest plate is pushed down, and the box 40
The compression confirmation switch 47 provided therein comes into contact with the compression slider 45, causing the compression confirmation sound signal device 52c of the sound signal device 50 to generate an electronic sound such as "Pooh, Pooh...".

Next, to briefly explain the cardiac muscle surge training, first, prior to the training, the patient listens to a pace sound such as the metronome sound mentioned above, and memorizes the rhythm of the heart muscle surge. Next, the pace sound for listening is turned off, and the mode of the sound signal device 50 is switched to the cardiac muscle surge training mode. Then, place your hand on the chest position taught and begin the pine surge.
If the hand position is correct, a first sound signal sounds;
When the chest plate is pressed with a predetermined compression force, a second sound signal is generated. In the embodiment, the first sound signal is a pace sound that sounds intermittently as "Pitsu, Pitsu,...", and the second sound signal is a buzzer sound that sounds "Boo, boo,..." for the duration of the press. has been done. Therefore, the trainee repeats chest compressions while listening to the pace sound. However, if the hand position is incorrect, the first sound signal will not sound and only the second sound signal will sound.
Indicates that the compression force is sufficient, but the compression position, that is, the position of the hand, is incorrect. Of course, if the compression force is too small, that is, if the chest plate is not pushed in too much, the second sound signal will not sound.

FIG. 8 is a wiring circuit diagram of the sound signal device of the above-described embodiment. Although the figure shows a relay system, it is also possible to use a short IC system or a transistor system.

(Effects) As illustrated and explained above, in the human body model for resuscitation training according to the present invention, expiratory insufflation or cardiac surge training can be confirmed by sound signals and together with the training motions, so It has a relatively simple structure, is trouble-free, and can be used safely and hygienically, and is especially useful as a human body model for beginners or for school education. Highly sexual.
