Description

CPR delivery aids (2)

The present invention relates to a cardiopulmonary resuscitation assistant, especially a device that can limit the pressure channel and depth, so as to keep the cardiopulmonary resuscitation stable, so as to avoid the occurrence of excessive force and break the ribs, so as to reduce the A CPR-administered aid for patients suffering other injuries.

Press, Cardiopulmonary Resuscitation (Cardiopulmonary Resuscitation, CPR) is a kind of emergency measures to rescue patients with cardiac arrest, artificially maintain brain function until natural breathing and blood circulation are restored. Once cardiac arrest occurs, if the patient is not rescued and resuscitated in time, it will cause irreversible damage to the human brain and other important organs and tissues in 4 to 6 minutes. Therefore, CPR after cardiac arrest must be performed immediately at the scene. The key to CPR lies in the three movements of "pressing", "lifting" and "blowing", "pressing" is chest compression, mainly Use chest compression to form a temporary artificial circulation, so that various tissues and organs can be perfused with blood; "lift" is to lift the chin to keep the airway open; "blow" is artificial respiration instead of spontaneous breathing. 30 times and then "blow" 2 times, this cycle to ensure blood circulation and oxygen exchange. For example, drowning, heart disease, high blood pressure, car accident, electric shock, drug poisoning, gas poisoning, foreign body blocking the airway, etc. Those who stop can use cardiopulmonary resuscitation to protect brain cells and organs from necrosis.

1 is a schematic diagram of a conventional human rib structure, wherein, the sternum 8 is located inside the human chest, and the ribs 9 are in multiple groups, and the left and right sides extend forward to surround and connect with the sternum 8 to form a thorax. Figure 2 shows a schematic diagram of the pressure change of the rib 9 before and after performing CPR on the human body while lying on his back, wherein, (a) the small picture shows the area surrounded by the rib 9 before performing CPR, (b) The small picture shows the state in which the sternum 8 is strongly pressed downward during CPR, and the ribs 9 that link the left and right are also pressed and pressed downward. When performing CPR, the above-mentioned "pressing" action is actually "external chest compression method". align the midline of the junction of the middle and lower 1/3 of the sternum 8 (usually the junction of the sternum 8 and the rib 9) with the palms of the palms, and press down from the outside of the patient's chest. The rate is 100~120 times per minute, and the compression depth is about 5~6 cm for adults (about 1/3 of the pressure in Figure 2), and about 4-5 cm for children and infants, mainly to press the heart to make the blood flow. The output is sufficient, so the compression depth must be controlled. At the same time, the operator should also pay attention to avoid leaning on the chest of the rescued patient excessively, so that the chest (and the heart) formed by the rib 9 can be used in the gap between the second compressions. Full rebound allows the heart to contract and dilate artificially to maintain blood flow.

At present, it is known that when performing the "pressing" action in CPR, because it is a tug-of-war with the god of death to save a life, the rescuers are often anxious and act in a hurry and quickly, eager to save the life from the god of death. It proves that saving lives is a sacred work. However, it is often very urgent, coupled with the use of bare hands and the anxiety of the rescuer, which leads to too much pressure and depth. Therefore, in the case of emergency rescue, the rib 9 is crushed and caused various injuries. It is a common thing. This is a serious defect caused by the use of bare hands during emergency rescue.
