Description
Technical field
The present invention relates to cardio-pulmonary resuscitation guidance device external on a kind of defibrillator, belong to the Medical Instruments technical field.
Background technology
According to statistics, the annual million people of China loses one's life because of sudden cardiac arrest, wants save lives, in time defibrillation.And the process of defibrillation must be accomplished in 10 minutes, defibrillation more early, the probability of bringing back to life is just big more.Maybe any at any time place and sudden cardiac arrest takes place, the professional health care personnel arrive in and have missed best therapeutic time basically by the time, so people have invented automated external defibrillator (AED).
Automated external defibrillator is to have increased automatic arbitration functions on the basis of traditional defibrillator; Can measure the physiological situation of human body automatically; Comprise electrocardio and human body impedance, judge that automatically whether human body needs defibrillation, calculates the size of required discharge energy automatically; Automatically accomplish the process of defibrillation, simplified the difficulty of operation greatly.Because its high simplified, the non-medical professional can operate according to the voice suggestion of machine through general training, and this just shortens patient by falling ill to the time of accepting electric defibrillation, for the sudden cardiac arrest patient can be given treatment to timely possibility is provided.
Recently people's research shows, in timely defibrillation, carries out effective cardio-pulmonary resuscitation (CPR), can improve the success rate of rescue greatly.The importance of in " cardio-pulmonary resuscitation and the cardiovascular first aid international guidelines 2010 " of new edition, having stressed in defibrillation, to carry out the cardio-pulmonary resuscitation of correct and effective; A correct cardio-pulmonary resuscitation is: each cardio-pulmonary resuscitation time is two minutes; Whenever push and do the artificial respiration for 30 times 2 times; In two minutes, accomplish 3 circulations, compression frequency at least 100 times/minutes according to pressing depth is at least 50 millimeters.
In existing automated external defibrillator; Much all have simple cardio-pulmonary resuscitation guiding function; Generally be to instruct through voice on the automated external defibrillator main frame and figure; But can not measure compression frequency and according to pressing depth, actual compression frequency and according to pressing depth depend on rescuer's experience.In application process, because the personnel that participate in to rescue are non-professional health care personnel, only limit to simply instruct mode, be difficult to accomplish correct compression frequency with according to pressing depth, this has just stayed hidden danger for the success rate of raising rescue.
Summary of the invention
In order to address the above problem, the invention provides a kind of can be on defibrillator external cardio-pulmonary resuscitation guidance device.Automated external defibrillator and cardio-pulmonary resuscitation guidance device are combined into one, and for the rescuer provides accurately and the cardio-pulmonary resuscitation of easy operating guidance, improve salvage success rate.
Cardio-pulmonary resuscitation guidance device among the present invention, its content comprises:
1. external cardio-pulmonary resuscitation guidance device on the defibrillator is characterized in that comprising: have and push box body (6), LCDs (1), acceleration of gravity pick off, main control chip, external interface (4) are housed in the box body; Wherein LCDs, acceleration of gravity pick off, external interface are connected with the main control chip respectively; Wherein external interface is used for being connected with the defibrillation main frame, and power supply and communication each other are provided.
2. external cardio-pulmonary resuscitation guidance device on the defibrillator is characterized in that pushing the groove (2) that the surface of box body has a suitable manual work to push.
3. external cardio-pulmonary resuscitation guidance device on the defibrillator, it is characterized in that pushing box body below have meet human body breastbone characteristic be close to presternal tongue (5).
4. external cardio-pulmonary resuscitation guidance device on the defibrillator is characterized in that pushing the sketch map (3) that individual guidance device riding position is arranged on the groove of box surface.
5. external cardio-pulmonary resuscitation guidance device on the defibrillator is characterized in that showing respectively on the LCDs that one does not touch sketch map (7), one and begins to push sketch map (8), one according to pressing depth sketch map (9), a compression frequency sketch map (10), open airway and artificial respiration's sketch map (11).
External cardio-pulmonary resuscitation guidance device on the defibrillator can correctly be measured the compression frequency and according to pressing depth of rescuer's reality, instructs through the figure that has on the guidance device, and the guiding rescuer makes correct compression frequency with according to pressing depth, the raising salvage success rate.

The specific embodiment
Shown in Fig. 1～7, the cardio-pulmonary resuscitation guidance device among the present invention mainly is made up of six parts, pushes box body (6); LCDs (1); The acceleration of gravity pick off; The main control chip; External interface (4); Control software.
Push box body:
Push box body and form, satisfy the above dustproof and waterproof requirement of IP55 by high voltage bearing plastic cement; Push the groove (2) that the surface of box body has a suitable manual work to push, groove can be close to people's the hands palm when pushing in that manual work is free-hand; Push box body below have meet human body breastbone characteristic be close to presternal tongue (5); Push the sketch map (3) that individual guidance device riding position is arranged on the groove of box surface.
LCDs:
LCDs is selected the LCD screen of the low-power consumption of customization for use, can show respectively do not touch sketch map (7), begin to push sketch map (8), according to pressing depth sketch map (9), compression frequency sketch map (10), open airway and artificial respiration's sketch map (11).Not touching sketch map representes to point out the rescuer not touch patient bright the time; Beginning to push sketch map representes to point out when bright the rescuer to begin patient done to push; Represent through the lattice number that according to pressing depth indicate when not expiring lattice to continue firmly to push, full lattice are to represent that the dynamics of pushing is much of that; Compression frequency is represented through numeral, as when numeral shows 100, representing that compression frequency is 100 times/minute; Represent to point out the rescuer to patient's open airway and do the artificial respiration twice when open airway and artificial respiration's sketch map are bright.
