Cardio-pulmonary resuscitation pressing depth indicating system with double sensors

Abstract

The invention discloses a cardio-pulmonary resuscitation pressing depth indicating system with double sensors. The system comprises the first acceleration sensor arranged at the front chest pressing position of a human body, and the second acceleration sensor arranged at the position, directly facing the front chest pressing point, of the back of the human body. The first acceleration sensor transfers numerical values induced by the first acceleration sensor to a first microprocessor to calculate a first pressing displacement value. The second acceleration sensor transfers numerical values induced by the second acceleration sensor to a second microprocessor to calculate a second pressing displacement value. The first pressing displacement value and the second pressing displacement value are transferred to a third microprocessor on a display device in a wireless or wired mode. The third microprocessor enables a difference value of the first pressing displacement value and the second pressing displacement value to be displayed on a display screen. The cardio-pulmonary resuscitation pressing depth indicating system can detect the true chest pressing depth accurately, improve the first-aid quality and display the pressing depth to a rescuer in real time for reference.

Description

technical field [0001] The invention relates to the technical field of medical first aid, in particular to a dual-sensor cardiopulmonary resuscitation compression depth indicating system. Background technique [0002] In medical emergencies, cardiopulmonary resuscitation is the most common and effective first aid method. Experiments have shown that during chest compressions, the depth and frequency of compressions directly determine the success of first aid. Therefore, the latest revised "2010 American Heart Association (AHA) Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC) Guidelines" According to the regulations, the frequency of compressions should be at least 100 times per minute, and the compression depth should be at least 5 cm. [0003] Existing chest compression methods mainly contain two types, one is automatic equipment compression, the compression equipment is driven by pneumatic or electric means, and the depth of compression is contro...

AI Technical Summary

Problems solved by technology

[0003] Existing chest compression methods mainly contain two types, one is automatic equipment compression, the compression equipment is driven by pneumatic or electric means, and the depth of compression is controlled by controlling the ejection length of the compression head (piston rod end); The second is manual compression, and the depth of compression is determined by the on-site rescue experience of the rescuer, the degree of pressure and other factors. In the process of first aid, high-frequency and high-intensity compressions have higher physical requirements for the rescuer. , it is difficult to guarantee the compression frequency and compression depth, which directly affects the rescue effect

[0004] The pressing depth in the above two rescue methods is only the depth of pressing down on the front chest cavity of the human body. In fact, since the back spine of the human body has a certain degree of curvature, and most of the positions where the patient lies are soft supports (such as soft beds, soft supports, etc.) pads, etc.), when the rescuer presses down from the patient's chest, the patient's entire chest cavity (front chest and back) will first move or deform for a certain distance under the pressure (see Figure 1-2 ), after the patient’s back is effectively supported, the rescuer’s downward pressure can deform the front chest downward, that is, start the cardiopulmonary resuscitation action. To achieve the effect of compressing the chest cavity, although the set compression depth is 5 cm, most of the compression movements cannot reach more than 5 cm

[0005] In addition, the existing cardiopulmonary resuscitation equipment cannot intuitively see the compression depth value, and cannot give the rescuer a reminder of the compression depth, so it will also have a great impact on emergency treatment
