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
The present invention relates to medical first aid technical field, particularly relate to a kind of dual sensor cardio-pulmonary resuscitation according to pressing depth indication mechanism.
Background technology
In medical first aid, cardio-pulmonary resuscitation technology is the most common is also the most effective first-aid method.Experiment shows, in enforcement chest compression process, the degree of depth and the frequency of pressing directly determine first aid success or not, therefore, regulation in " 2010 American Heart Association (AHA) cardio-pulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) guide " of up-to-date revision, compression frequency at least wants 100 beats/min, according to pressing depth at least wants 5 centimetres.
Existing chest compression mode mainly contains two kinds, and one is that apparatus presses automatically, and this pressing apparatus adopts pneumatic or electronic mode to drive, the degree of depth of pressing then by control press head (piston rod end) eject length to control; The second is artificial pressing, according to pressing depth then relieve the factor such as experience, pressing dynamics by the scene of rescuer to determine, require higher in the push action of first aid procedures high frequency, high strength to the body constitution of rescue personnel, once being short of physical strength of rescue personnel, then compression frequency and according to pressing depth very difficult guarantee, and then directly affect success in salvage.
The depression depths be according to pressing depth only human body prosocoel in its above-mentioned two kinds of rescue modes, in fact, because human body back vertebra has certain flexibility, and the position majority that patient lies is for flexible support thing is (as soft bed, cushion etc.), when rescuer presses downwards from patient chest, the whole thoracic cavity of patient (shirtfront and back) can first move downward or be out of shape certain distance (see Fig. 1-2) under the effect of the pressure, after effectively being supported at patient back, the downforce of rescuer just can make shirtfront be out of shape downwards, also namely start to carry out cardio-pulmonary resuscitation action, therefore, sue and labour in process actual, initial one end time of push action does not play the effect in compressing thoracic cavity, although setting is according to pressing depth 5 centimetres, but the push action of the overwhelming majority does not all reach more than 5 centimetres.
In addition, existing cardio-pulmonary resuscitation equipment can not be seen intuitively and being according to pressing depth worth, and can not give rescuer one prompting according to pressing depth, therefore also can affect greatly emergency treatment.
