{Cardiopulmonary Resuscitation training device}

The present invention relates to a CPR exercise device, and more particularly, to a CPR exercise device provided in a CPR, a school, a workplace, or a home, so that an actual CPR can be easily learned.

In general, cardiopulmonary resuscitation is a treatment that restores cardiopulmonary function when the cardiopulmonary function is severely impaired or stopped. For normal respiratory function or respiratory arrest, first confirm the consciousness, secure airway, perform artificial respiration, To restore function, perform a heart massage.

First, confirm the consciousness by tapping the shoulder, and then secure the airway. Prayer refers to the passage of air through the nose, mouth, pharynx, larynx, bronchus, etc. When the heart stops and stops breathing, the muscles of the tongue are lowered to enter the pharynx, causing airway obstruction. Airway obstruction is more common in patients with congestive heart failure and respiratory arrest, as well as head trauma and strokes.

Cardiopulmonary resuscitation, which is a first aid measure to maintain blood circulation while artificially maintaining breathing for a person who has stopped breathing or heartbeat, is a crucial help in recovering from heart failure while delaying damage to the brain in an emergency.

Such cardiopulmonary resuscitation should be performed at a compression rate of at least 100 times per minute and at most 120 times per minute at a depth of 4 to 6 cm in which the heart is located.

A constant rate should be maintained with adequate pressure to compress the chest to the same depth.

However, if there is no experience to maintain adequate compression rate in the event of a real situation, it may be too late or too fast to cause cardiopulmonary resuscitation or cause physical injury.

Therefore, it is necessary to practice or practice proper compression speed for the application of CPR in advance.

In the present invention, the output unit 160 may be a speaker for generating sound. Meanwhile, the output unit 160 may be connected to the PCB unit 150 by electric wires, and may be operated by receiving power.

Accordingly, in the present invention, for example, when the number of times that the operation unit 153 is sensed by the sensing unit 151 for 10 seconds is 18, the resultant value of the normal speed is sent to the signal unit 155, "The speed is normal so I can tell it is normal speed. If the number of times that the operation unit 153 is detected by the sensing unit 151 for 10 seconds is 18 times, the result of the normal speed is sent to the signal unit 155, (160) to see that the speed is normal "Speed is normal. Etc., and the exercises were completely performed through the output unit 160 at the normal speed for three consecutive times. It is possible to maximize the learning effect.

If the number of times that the operation unit 153 is detected by the sensing unit 151 is less than 18, for example, the operation unit 153 sends a result indicating that the operation unit 153 is slower than the normal speed to the signal unit 155, "It's slow, I'll try again." If the number of times that the operation unit 153 is detected by the sensing unit 151 for 10 seconds exceeds 18 times, a result indicating that the normal speed is fast is outputted to the signal unit 153. [ (155), and the output unit (160) sends the message "Speed is fast. It is possible to maximize the learning effect by making it easier for the human to recognize it.

For reference, the optimal compression rate for CPR is less than 100 times per minute, less than 120 times per minute, and more than 16 times to less than 20 times per 10 seconds.

Therefore, although the best compression rate in CPR is 17, 18, or 19 per 10 seconds, the present invention has set the median value of 18 times as an example, but the present invention can be set to be performed within the range of 17 to 19 have.
