Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a human body model for training resuscitation in respiratory arrest and cardiac arrest.

When a person suddenly goes into a state of respiratory arrest or cardiac arrest due to trauma such as a traffic accident or sudden illness, the first three to four minutes can be the difference between life and death. In such cases, it is necessary to perform emergency resuscitation and take life-saving measures as soon as possible.

In recent years, it has become widely recognized in Japan that it is important for the general public to learn this emergency resuscitation technique, and it is being incorporated into junior high and high school education. Emergency resuscitation methods include artificial respiration using exhaled air and cardiac surges, but when practicing these methods, it is extremely dangerous to practice on a living body, such as a friend, and in this case, especially the above-mentioned exhaled air injection. And a human model for training of cardiac pine surge is required.

This invention was developed under these circumstances.
To provide a human body model that can produce practical and excellent training effects, such as confirming the correctness of emergency actions during training, or controlling the correct pace of cardiac muscle surge, using a sound signal device such as an electronic sound. With the goal.

Jin's inventions include an expiratory blow training device with simulated respiratory organs and a cardiac muscle surge training device with a simulated chest structure, but these two training devices can be incorporated into a single human body model. , and practical.

The exhalation blowing device of the present invention uses a human body model having a simulated head and chest, and includes an insufflation tube that communicates with the mouth and nose of the head and reaches the inside of the chest, and an insufflation tube that is placed on an original plate and connected to the insufflation tube. a pavement connected via a check valve, an exhaust pipe for discharging the air in the instrumentation to the outside of the human body, and an exhalation slider that passes through a notch in the joint plate and moves forward with the chest plate that bulges as the pavement expands; and a sound signal device activated by sliding the exhalation slider to a predetermined position. The cardiopulmonary surge training device consists of a chest plate that is elastically supported to move up and down under a predetermined pressure in a human body model with a simulated chest, and a chest plate that is installed on the surface of the chest plate and generates sound by compressing a predetermined position of the chest plate. It is characterized by comprising a hand position confirmation switch that activates a signal device and generates a first sound signal, and a compression slider that activates the sound signal device and generates a second sound signal by vertical movement of the chest plate.

A detailed description of the invention will be given below with reference to the accompanying drawings.

First, the exhalation blowing training device of the present invention will be described. The blowing tube 31 is connected so as to communicate with the mouth portion 11a of the simulated head 11 and the airway portions of the nose portion 1b], 1c. This blowing pipe 31 is preferably a flexible bellows-shaped pipe.

The blow pipe 31 communicates with the pavement 3o placed on the decorative plate 25 via a check valve 35 and a connector 36. On the other hand, a discharge pipe 37 is connected to the check valve 35, so that the air within the pavement 3o can be discharged from the discharge port 3 to the outside of the human body. The air blown from the blowing pipe 31 and the mouth part], 1a or the installation part 111)
The flow of air discharged from the pavement 30 through the discharge pipe 37 to the discharge port 38 is controlled in one direction by the check valve 35.

As can be better understood from Figures 3 and 5,
A slider switch box 4o is fixed on the back side of the joint plate 25, and an exhalation slider 4 is installed in the box 40.
1 penetrates the notch 26 of the joint plate 25 and is elastically attached by a spring 42 so as to have an elastic force toward the chest plate 15 side. As shown in Figure 4, the pavement 30
A hole 39 is formed at a position corresponding to the notch 26 in the original plate 25, and the tip of the exhalation slider 4 is connected to the chest plate 15.
It is configured to come into direct contact with the back surface. Therefore, lung bag 3
When air is blown into the interior of the pavement 30 and it expands, the pavement 30 pushes up the chest plate 15 and makes it bulge, as shown in FIG. Since the exhalation slider 4 is in elastic contact with the chest plate 15, it moves forward (raises) by the elastic force of the spring 42 as the chest plate 15 rises. and the exhalation slider 4
1 is the predetermined position e! , when moving forward, the limit switch 43 installed in the slider switch box 40 is turned on and the sound signal generating section 52A is activated.
It generates an electronic sound that goes, "Horo ho ho ho ho...". This sound signal d1 is designed to be activated when more than approximately 1.0 OOcc of air, which is the appropriate amount of exhaled air blown into the pavement 30, is blown into the pavement 30.

In addition, in FIG. 3, reference numeral 27 indicates a notch for connecting the pavement 30 and the check valve connector 36, 2B indicates an air relief groove, and reference numeral 36a in FIG. 4 indicates a connection portion between the pavement 30 and the check valve connector 36. .

Next, the cardiac massage training device will be explained. The three important points in cardiac massage training are confirmation of the compression position, that is, confirmation of the hand position, compression force, and rhythm.

This invention includes a hand position confirmation switch that is activated by compression on a predetermined position of the chest and generates a first sound signal, and a compression slider that is activated by a predetermined compression force and generates a second sound signal. alone, depending on
The present invention still relates to a structure capable of generating a base sound such as a metronome sound as a 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 elastic support member 21 erected on the back plate portion 14. 21
15 chest plates are supported so that they can elastically move up and down with a predetermined pressure. As is clear from FIG. 3 or FIG.
2, an inner cylinder 23b fixed to the original plate 25 on the chest plate 15 side, and a spring 2175.
) to a predetermined depth of about 1/4 of the chest, about 4.5
cm) Its elastic force is set so that it sinks.

In order to confirm the position of the matsuzage, the chest plate] -5 side,
In this embodiment, a hand position confirmation switch 6o consisting of a thin plate-shaped micro two-point switch as shown in FIG. 7 is installed at a predetermined position on the lower surface of the chest plate. This hand position confirmation switch 6
o cannot be turned on unless two switch buttons 61 and 62 are pressed at the same time, and a protrusion 63 is provided on the outer periphery of the button to prevent it from being activated easily unless a predetermined amount of pressure or force is applied to the chest plate. It is installed protrudingly. This hand position confirmation switch 60 is the sound signal generator 5 of the sound signal device 50 in FIG.
Activate 2B.

In this case, it is preferable that the current sound signal is a bass sound at regular intervals (for example, 60 times per minute) such as a metronome sound, in order to help the student learn the rhythmic pace. In addition, if this sound signal is a bass sound, Pine Surge! It is desirable to incorporate a circuit that operates separately from the hand position confirmation switch 6° so that the bass sound can be heard prior to II m.

Furthermore, the vertical movement of chest plate] 5 during pine surge (d,
It is sensed by the limit switch 47 of the slider switch box 40 and generates a second sound signal different from the first sound signal produced by the hand position confirmation switch 60.

That is, as shown in FIG.
is attached to the slider switch box 40 with an elastic force applied to the back plate part] 4 side by a spring 46, and is applied to the chest plate with a predetermined compression force against the elastic force of the elastic support member 21], 5 When pressed, the slider switch box 4o fixed to the original plate 25 at the lower part of the chest is pushed down, and the limit switch 47 provided inside the box 4o is pressed down.
and the compression slider 45 come into contact, activating the sound signal generating section 52c of the sound signal device 5o, e.g.
An electronic sound "..." is generated.

Next, to briefly explain the 111 training of the heart pine, first, before training, for example, the player listens to the pace sound of the metronome candle as mentioned above, and memorizes the rhythm of the heart pine 1-ji. Next, the pace sound for listening is turned off, and the mode of the sound signal device 50 is switched to cardiac muscle mass training. Then, place your hand on the chest area you were taught and begin the pine massage. If the hand position is correct, a first sound signal will sound, and if the chest plate is pressed with a predetermined compression force, a second sound signal will sound. In the embodiment, the first sound signal is a pace sound "beep".
The second sound signal is configured to sound intermittently as "Beep, Boo,..." and the second sound signal is a buzzer sound that sounds as long as the button is pressed. Therefore, the Ill practitioner must repeat chest compressions after hearing 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, indicating that although the compression force is sufficient, the compression position and the position of the hand are 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. The figure shows one type of relay, but there are also
It is also possible to use a C type or a transistor type.

As illustrated and explained above, in the human body model for resuscitation training according to the present invention, exhalation insufflation or cardiac massage training can be confirmed with sound signals and training movements, so that practical and excellent training can be carried out. It is effective, has a relatively simple structure, is trouble-free, and can be used safely and hygienically, and is particularly useful as a human body model for beginners or for school education.
