Description
Technical field
The present invention relates to a kind of portable cardio-pulmonary resuscitation equipment, being specifically related to one is fused in cardio-pulmonary resuscitation equipment by human body physical sign measuring ability, determined the physiologic information state of patient by the specialist system that control system is embedded, ensure the portable cardio-pulmonary resuscitation equipment merged based on sign information of best therapeutic effect.
Background technology
People in life, based on inevitably arrhythmia occurring, and serious arrhythmia even causes sudden cardiac arrest, and often occur suddenly, treatment success rate is low.In the U.S., sudden cardiac arrest is the first cause of death, seizes the life of 250,000 people every year, and considerably beyond the summation dying from acquired immune deficiency syndrome (AIDS) after breast carcinoma, pulmonary carcinoma, apoplexy every year, and in China, this numeral is also in continuous rising.Expert points out, the sudden cardiac arrest of more than 80% is all quivered caused by room.Its fatality rate is very high.After heart stops suddenly beating, effective blood-pumping function disappears, and causes whole body severe depletion of oxygen, ischemia.Clinical manifestation is beaten and hear sounds disappearance less than large artery trunks for laying one's hand on; Then loss of consciousness, respiratory arrest, platycoria, can cause death if rescue not in time.The overwhelming majority patient's heart all standing after can cause body tissue's cell severe ischemic, anoxia and dysbolismus due to the termination of cardiac pump function and Efficient Cycle.It is generally acknowledged, asystole 5 ~ 10s can occur dizzy or faint, and can occur fainting and twitching more than 15s, can occur stupor more than 20s; Late one minute of sudden cardiac arrest patient conversion, survival rate reduces at least 10%.If asystole often causes the irreversible lesion of brain in patients and organs in adult more than 5min, cause death, even if rebeating also often leaves over sequela in various degree.Therefore, sudden cardiac arrest is emergency case the most critical clinically, must race against time and actively rescue.
After sudden cardiac arrest occurs, topmost emergency measures correctly carries out cardio-pulmonary resuscitation in time.Cardio-pulmonary resuscitation is for sudden cardiac arrest, is intended to set up Efficient Cycle as early as possible, improves cardiac output and the series of measures taked.Research shows, the asystole time is longer, body tissue particularly cerebral tissue to stand the infringement of anoxia more serious, the probability sustained life is less.Therefore, the key of sudden cardiac arrest successful rescue is the morning and evening starting rescue time.According to statistics, case 64% first aid in 4min after asystole of success of cardiopulmonary resuscitation, therefore proposing to rescue best opportunity of sudden cardiac arrest is after asystole in 0 ~ 4min.And asystole great majority occur in outside institute, both without medicine, again without crash equipment, therefore organize the rescue work immediately on the spot, nearby, must guard against wait-and-see or pass at a distance, just seem particularly important.
Closed cardiac massage method: be the most basic prefered method of salvage at scene, must carry out immediately, be one of cardiac resuccitation key measure.First or patient should be allowed to lie on the back sleep on hard place at patients back pad one piece of plank, to strengthen pressing effect.To the patient that sudden cardiac arrest may occur in hospital, as acute myocardial infarction, severe arrhythmia patient all should routine to sleep hardboard bed, once generation sudden cardiac arrest, closed cardiac massage can be implemented immediately.Thought that the action principle pressed was the result directly extruding heart, make heart arrange blood when pressing breastbone, when loosening, then diastole makes the blood backflow chambers of the heart in the past.Think that pressing mainly causes intrathoracic pressure universality to increase at present, promoting blood flow, makes intrathoracic pressure generally reduce when loosening, and promotes that venous blood flows to the right heart, to reach the object maintaining effective blood circulation.
Human body cardio-pulmonary resuscitation technology used mostly at present is manual chest compression (circulation; C); concrete operation method is as follows: guarantee that patient lies supine is on level land or under being padded on its shoulder back of the body with external chest compression plate; first aid person can adopt the different position such as the formula of kneeling or foot-stool; the palm root of a hands is placed on the central authorities of patient chest; in breastbone Lower Half, the palm root of another hands is placed in first on hand, finger does not contact thoracic wall.
During pressing, duplex must stretch, vertically downward firmly pressing, and adult compressions's frequency is at least 100 times/min, and depression depths is at least 125px, thorax should be allowed to reply completely after each pressing.Compressing time and relaxation time respectively account for about 50%, slap root and can not leave thoracic wall when loosening, in order to avoid press points displacement.For child patient, with singlehanded or both hands in nipple line horizontal pressing breastbone, for baby, point with two and transfer horizontal pressing breastbone in being close to nipple line.Interrupt external chest compression in order to reduce as far as possible because of ventilation, for the adult not setting up artificial airway, the pressing-Ventilation Ratio of international cardiopulmonary resuscitation Guidelines recommend in 2010 is 30:2.For immunoenzyme technics, the ratio of 15:2 during double CPR, can be adopted.As double or many people sue and labour, every 2 minutes or 5 cycle CPR (each cycle comprises 30 pressings and 2 artificial respirations) pressing person should be changed, and conversion is completed within 5 seconds, because research shows, in pressing beginning after 1 ~ 2 minute, the quality of operator presses just starts to decline (showing as frequency and amplitude and thoracic wall reset case all undesirable).Can find, there is some problem following in manual cardiopulmonary resuscitation's technology:
1, operator consumes a large amount of muscle power at the rescue operations initial stage, cannot ensure to press quality, can not continue, standard presses;
2, in without professional's situation, do not have standard intraocular's cardio-pulmonary resuscitation condition, substantially correctly cannot save patient vitals;
3, rescue personnel needs mouth-to-mouth insufflation, is subject to courses of infection, cannot ensure that rescue personnel's is healthy;
4, the change of the sign state of patient cannot be understood while rescue, information cannot be provided for next step treatment.
In order to solve artificial first-aid Problems existing, medical skill workers devise mechanical cardio-pulmonary resuscitation equipment, the pressing process manually completing cardio-pulmonary resuscitation is replaced by machinery, but, current cardio-pulmonary resuscitation equipment on the market only has the function of simple pressing, cannot meet changeable environment and the demand of patient, mainly there is following two problems in this kind equipment:
1, function is simple, completes push action merely, cannot know that patient sign converts;
2, intelligent deficiency, untrained personnel cannot go up hand operated easily, and practicality is not strong.
