Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body model used for learning and training of a human resuscitation method.

[0002]

2. Description of the Related Art A human body model for resuscitation training is used for learning and training of airways, artificial respiration, and heart massage. Some human body models are provided with means for notifying by sound or light whether or not each of these resuscitation methods is properly performed. For example, the operation of tilting the head backward to secure the airway (head backward bending) detects the position and inclination of the head of the human body model with respect to the neck,
There is a human body model that notifies whether or not the operation is correct based on the detected position information and inclination information. In addition, by the operation of inhaling the expiration of artificial respiration, the height of the chest, which changes due to the expansion of the bag caused by the inhalation of the expiration into the bag as a lung model arranged on the chest of the human body model, is detected, and the detected height is detected. There is a human body model that is informed whether an appropriate amount of air is blown based on information. In the case of artificial respiration, there is also a human body model of a type in which whether or not the exhalation is inhaled is notified at an appropriate timing. In addition, in the chest pressing operation of heart massage,
There is a human body model that informs whether the hand is placed at the correct position on the chest, whether the pressing force of the hand is sufficiently large, and whether the pressing timing is appropriate.

[0003]

With the provision of the above-mentioned notifying means, the technology required for the resuscitation
It is possible to learn quasi-empirically while checking whether each treatment operation is performed correctly. However, at the site, even if the head is bent backward, the base of the tongue may fall into the back of the throat and the airway may not be secured, or a rib of the subject may be broken by a heart massage. Whether traditional resuscitation training human models have learned how to deal with or avoid these situations,
I could not confirm.

Accordingly, an object of the present invention is to provide a resuscitation training human body model that can confirm whether the resuscitation operation is correct.

In the output device 90 of the present embodiment, when the switch of the pressure sensor 103 is turned on, a red lamp is lit on the item of airway securing on the display unit 92, and when the switch of the pressure sensor 103 is off, the item of airway securing is The green lamp lights up.

The use of the head 10 of the human body model 1 and the neck 5 of the base 3 enables training of securing the airway by bending the head backward and / or raising the chin. First, the human body model 1 is set to the natural state shown in FIG. 1, and the power is turned on. In the natural state, as shown in FIG. 4, the distance between the tongue base 24 of the lower jaw 20 and the airway back part 36 of the head internal bone 30 is short and less than a predetermined value. This is a model of a state in which the airway is obstructed by the subsidence of the tongue base where the base of the tongue is depressed in an unconscious person. For this reason, FIG.
As shown in FIG. 1, the pressure sensor 103 is sandwiched between the tongue base 24 and the distal end of the airway back part 36 and is crushed and turned on, and the display unit 9 of the output device 90 shown in FIG.
In 2, the red lamp is lit for the item of airway obstruction.

In the case of training for back bending of the head, the jawbone 22 of the lower jaw 20 in the state shown in FIG. 4 is held and held with one hand, and the forehead of the head 10 is pressed with the other hand. While lifting, the lower jaw 20 is lifted upward on the face. By this operation, the head 10 is rotated backward with respect to the neck 5, and the operation of bending the head backward is completed. When the head 10 rotates, the internal bone 30 in the head 10 also slides with respect to the neck 5 while rotating with respect to the head 10, and moves rearward inside the head 10. For this reason, the airway back part 36 moves toward the occipital region, and the airway back part 36 and the tongue base 2 of the lower jaw 20
4 becomes large. Then, as shown in FIG. 5 (b), when the distance between the tip of the airway back part 36 and the tongue base 24 becomes equal to or greater than a predetermined value, the pressing force of the pressure sensor 103 decreases, and the switch of the pressure sensor 103 is turned off. Turn off. At this time, on the display unit 92 of the output device 90 shown in FIG. 1, the red lamp of the item of airway securing is turned off, and the green lamp of the item of airway securing is turned on. For this reason, the user can confirm whether the airway has been secured by performing the work of bending the head backward as described above.

On the other hand, when performing chin lift training, the jawbone 22 of the lower chin 20 in the state shown in FIG. 4 is firmly grasped by hand and pulled up. At this time, the jawbone 22
Either a method of pulling up so as to sandwich both side surfaces and a method of inserting a thumb into the oral cavity and putting the thumb inside the jawbone portion 22 and pulling up can be performed. Further, when the airway cannot be secured even when the head is flexed, the procedure can be performed after the head flexion. By raising the lower jaw portion 20, the lower jaw portion 20 moves to the front side of the face so that the lower jaw connecting shaft 14 of the head 10 slides in the connecting groove 28 of the connecting portion 26, and the jaw lift is increased. Complete. In this case, the lower jaw 20 is the airway back 36
, The distance between the tongue base 24 of the lower jaw 20 and the tip of the airway back 36 increases. Then, as shown in FIG. 5A, when the distance exceeds a predetermined interval, the switch of the pressure sensor 103 is turned off, and the red lamp of the item of airway securing on the display unit 92 of the output device 90 shown in FIG. Then the green lamp of the item of airway securing lights up. For this reason, the user can confirm whether the airway was secured by raising the chin.

As described above, in the human body model 1, by merely providing the pressure sensor 103, whether the airway is secured by the head backward bending or the airway securing method by raising the chin is determined whether the airway is secured. It can be done while checking. That is, even if the head is flexed normally, the airway is not secured due to the poor position of the lower jaw, or the head cannot be flexed due to damage to the neck, and the airway can only be lifted by the chin lift. By using the human body model 1, it is possible to surely learn a method of securing an airway that can cope with any situation, such as when it is necessary to secure the airway.

Incidentally, the human body model 1 can be provided with a back bending abnormality notifying means for notifying the head back bending abnormality. Backward bending abnormality notification means includes, for example, an output device 90 shown in FIG.
As shown in FIGS. 2 and 4 to 6, the pressure sensor 123 can be configured as a position detecting unit that detects the position of the slide shaft 9 that moves in the slide ring 39 of the internal bone part 30 of the head. In this case, the slide ring 39 is provided in a longer shape in the front, that is, in the front direction of the head. Further, the pressure sensor 123 is disposed at a front portion of the slide ring 39 so as to contact the slide shaft 9. If the head 10 is tilted backward too much when the head is bent backward, as shown in FIG. 6, the slide shaft 9 moves to the front end side of the slide ring 39, and the pressure sensor 123 is bent. In the folded pressure sensor 123, both sides are in contact and the switch is turned on, and the position information is transmitted to the output device 90 shown in FIG.
A red lamp is turned on for the item of back bending abnormality (not shown) of the display unit 92. By providing the back bending abnormality notification means, it is possible to acquire a more correct operation for securing the airway.

In the pressing pitch notifying means, the detecting means can also be used as the pressing force notifying means or the pressing position notifying means. The pressing pitch notifying means has an appropriate pressing pitch stored in the memory in advance in the processing device 105 as a determining means. Then, the timing at which the switch of the detector 151 or the touch sensor 143 is turned on is compared with the stored pressing pitch to determine whether the switch is turned on at an appropriate pitch.

A method of training a heart massage using the human body model 1 will be described. First, the human body model 1 is set to the natural state shown in FIG. 1 and the power is turned on. In the natural state, as shown in FIG. 7, the distance between the chest plate 50 and the substrate 70, that is, the distance between the mounting table 53 of the movable unit 51 and the receiving table 73 of the fixed unit 71 is kept at a maximum. The detector 151 of the notification means is the most extended, and the switch is off. Next, both hands are put on the chest plate 50 so as to overlap with each other, and the weight is pressed in a direction perpendicular to the chest plate 50. When a pressing force is applied, the mounting table 53 is pressed via the breast plate 50, and the coil spring 60
Move toward the base portion 3 against the elasticity of the substrate. When the pressing force is released, the mounting table 53 and the breast plate 50 quickly return to their original positions due to the elasticity of the coil spring 60, so that the breast plate 50 can be intermittently pressed at a predetermined time interval (pitch). .

In the natural state shown in FIG. 7, the inclination notifying means is provided with the pressure sensor 133 as shown in FIG.
7 is not pressed. For this reason, the switch is turned off, and the green lamp is turned on in the item of the pressing direction of the display unit 92 of the output device 90 shown in FIG. When the user presses the chest plate 50 in the above manner, the fixing portion 71 is inclined with respect to the substrate 70 in accordance with the inclination in the pressing direction.
When the pressing direction is substantially perpendicular to the chest plate section 50, as shown in FIG. 9, the fixing section 71 moves downward while maintaining the balance with respect to the substrate 70. At this time, the pressing element 137
As shown in FIG. 9, the switch does not turn on because the pressure sensor 133 is only lightly pressed. For this reason,
The green lamp continues to light in the item of the pressing direction of the display unit 92 of the output device 90.

On the other hand, when the pressing direction is inclined by a predetermined angle or more from the direction perpendicular to the chest plate 50, as shown in FIG.
The presser 137 on the side where the fixing portion 71 is inclined and has largely moved downward is strongly pressed against the pressure sensor 133. For this reason, the pressure sensor 133 is crushed and the both sides come into contact, and the switch is turned on. The inclination information is transmitted from the pressure sensor 133 to the output device 90 of FIG. 1 via the processing device 105 shown in FIG. A warning sound is emitted. Since the switch of the pressure sensor 133 is turned off as soon as the pressing is released, the pressing direction is detected and notified every time the pressing is performed.

Therefore, the user always exercises the heart massage while confirming by sound or light whether the pressing direction applied to the chest 50 is perpendicular to the chest 50 (whether or not pressing in the direction of the spine). Can be.
Further, since the human body model 1 is also provided with a pressing position notifying unit, a pressing force notifying unit, and a pressing pitch notifying unit, it is determined whether the pressing position of the chest plate 50 is correct, whether the pressing force is appropriate, whether the pressing pitch is correct. Can be trained in heart massage while simultaneously checking that it is appropriate.

The human body model 1 includes an airway model 40,
The provision of the check valve 48 and the lung model 46 enables training of artificial respiration. In the training of artificial respiration, the airway is secured by any of the methods described above, and after confirming by the display unit 92 of the output device 90 whether the airway is secured, the nose 161 illustrated in FIG. After closing the mouth, the mouth is placed on the oral cavity 163, and exhaled air is blown from the opening 42 of the airway model 40. The exhaled breath is sent into the lung model 46 through the tube 44 and the check valve 48 as shown in FIG. The lung model 46 inflates when exhalation is delivered, and pushes up the chest plate 50. The user can confirm the lifting of the chest plate 50. Further, since the human body model 1 is provided with the air supply amount notifying means, the output device determines whether or not the necessary amount of air has been blown in by turning off the switch of the detector 153 which is in contact with the chest plate. 90. Therefore, in the human body model 1, the three types of resuscitation methods of securing the airway, artificial respiration, and heart massage can be combined or systematically trained.

In the present embodiment, the human body model 1 is used for training various resuscitation methods. However, the present invention is not limited to this. The human body model of the present invention can also be configured as a human body model that can train any of the treatment methods described above, or any combination thereof. For example, a human body model having only a head and a neck portion provided with interval notification means and capable of performing only training of airway securing may be used, or a human body model having a structure capable of performing training of airway securing and artificial respiration may be employed. Further, it may be a human body model for cardiac massage training provided with means for informing the inclination of the chest.
In particular, a human body model for heart massage training may have a configuration of only the torso of the human body, or may have a shape that is not considered to model the human body at first glance. Further, in these exemplary human body models, a human body model that can be further trained by combining any of the above-described treatment methods can be used. Furthermore, the configuration of the human body model of the present invention can also be achieved by incorporating the interval notifying means and the tilt notifying means according to the present invention into a conventionally known human body model.
