Description

Cardiopulmonary resuscitation (CPR) delivery aid

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 CPR being performed When the sternum 8 is strongly pressed downward, the ribs 9 connected to the left and right are also pressed and lead to a state of downward pressing. 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 depth of compression must be controlled. At the same time, the operator should also pay attention to avoid leaning too much on the chest of the rescued patient, so that the chest (and 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.

In view of this, the inventor of the present invention has made further research and improvement, hoping to provide a cardiopulmonary resuscitation assistant device that can limit the pressure channel and depth. After many efforts, the present invention was born.

Please refer to FIGS. 3 to 6 , an embodiment of the present invention is an application aid 10 , that is, an aid used in performing cardiopulmonary resuscitation. The application aid 10 is mainly composed of a base 1 and a stopper 2. It consists of an elastic member 3 and a pressing plate 4, wherein the base 1 is made of flexible materials (such as composite materials containing silicone, rubber, plastic, etc.), forming an oval shape with smooth top and bottom surfaces The surface is suitable; the stopper 2 is a columnar body, the top surface is slightly arc-shaped, and there are many protrusions 21 protruding on the arc-shaped top surface, and the stopper 2 is fixed to the The center of the top surface of the base 1; the elastic member 3 can be highly compressed due to pressure, and can be restored when the pressure disappears, such as: the elastic member of the scroll spring, the elastic member of the straight spring or the accordion shape Any elastic member of the wall body can be used. One end of the elastic member 3 is fixed on the top surface of the base 1; , to form an ellipse corresponding to the base 1, the bottom surface of the pressing plate 4 is a smooth surface for the top of the elastic member 3 to be fixed, and the top surface is smooth at the outer edge, and then slightly concave inward and downward to form a concave arc surface 44, the center of the concave arc surface 44 is provided with a through hole 45 extending downward, the position of the through hole 45 corresponds to the stopper 2, and the inner diameter of the through hole 45 is slightly larger than the stopper 2 , and the inner edge of the top end of the elastic member 3 is slightly larger than the inner diameter of the through hole 45 .

When performing cardiopulmonary resuscitation, the operator (rescuer) places the application aid 10 at the application site, generally aiming at the intersection of the patient's sternum 8 and ribs 9, and must make the application aid 10 . The base 1 is attached to the skin of the patient's chest (that is, the restraint such as clothes has been released), and then the palm root part where the palms are stacked is placed in the concave arc surface 44 of the pressing plate 4 (as shown in the small picture of Fig. 6 (a) ) (shown), and start to press down to perform CPR (shown in (b) in Figure 6). The rate of pressing is 100~120 times per minute. The pressing plate 4 compresses the elastic member 3 downward, and the base 1 is also pushed by the elastic member 3, and further pushes the patient’s ribs 9 to compress downward (inwardly) (as shown in FIG. 5). It must be mentioned that The thing is, when the base of the hand of the practitioner pushes the pressing plate 4 down, although the base 1 is also pushed down by the elastic member 3, but the base 1 is the active side because of the force of the base of the hand of the practitioner. The push down is the passive side, so when the force of the active side is greater than the passive side, the descending speed of the pressing plate 4 will be higher than the descending speed of the base 1, so at the moment of pressing, the root of the operator's palm will The through hole 45 touches the protrusions 21 (shown in FIG. 5 ) on the arc-shaped top surface of the stopper 2 . At this time, the base of the palm may be slightly stabbed or the stopper 2 may be affected by the pressing action. stop, so the operator knows not to press hard any more, and then at the moment when the force is released (released), the rib 9, the base 1, the elastic member 3 and the pressing plate 4 all return to the original position and shape upward. .

Then, the operator presses the pressing plate 4 again to compress the elastic member 3 and the base 1 to press down on the rib, and the base of the palm is stopped by the stop member 2 in an instant to stop applying force, so that the rib 9, The base 1 , the elastic member 3 and the pressing plate 4 are all restored upwards, so that the continuous pressing of the palm root, releasing the pressing, fast pressing, releasing the pressing, and ---- is fast. The action of pressing the patient's chest through the application aid 10 can also achieve the action of "pressing" in CPR. However, the present invention has the following excellent effects:

(1) During the process of pressing force by the operator, the base of the palm will be stopped by the stopper 2 and stop, so it can avoid the situation that the rib is broken due to excessive force, so as to reduce the risk of other patients suffering from other diseases. harm.

(2) During the process of pressing force by the operator, the base of the palm will be stopped by the stopper 2, so the pressure channel and depth can be limited, so that the application of CPR can be kept stable.
