Description
Technical field
The present invention relates to a kind of cardio-pulmonary resuscitation guidance device of using when rescuing the cardiac arrest patient.Belong to the medical apparatus technical field.
Background technology
It is unique when sudden cardiac death takes place that to make its rescue of surviving be cardio-pulmonary resuscitation.
Substantially (free-hand) cardio-pulmonary resuscitation comprises two contents: timely, effective closed cardiac massage and life-kiss.
Closed cardiac massage will reach effective effect, must guarantee in the operation accurately compression frequency (100 times/minute) and push dynamics (breastbone sink 40～50 millimeters).Otherwise will cause invalid or poor efficiency is pushed, perhaps bring danger, finally all may make the cardio-pulmonary resuscitation failure.Again revised " international cardio-pulmonary resuscitation guide " rose to unprecedented height to the significance of continual effective external chest compression especially in 2005.But, " international cardio-pulmonary resuscitation guide 2005 " pointed out again, implement studies show that of cardio-pulmonary resuscitation at the medical worker, 50% closed cardiac massage amplitude too shallow (less than 40 millimeters), and push in time of 24%～49% in the implementation process, on average only be 56 times/minute to such an extent as to make its compression frequency.Tracing it to its cause, this mainly reaches set standard with inspection equipment in order to guarantee operation because of lack monitoring in the cardio-pulmonary resuscitation implementation process.For example the dynamics of the closed cardiac massage pressure of " international cardio-pulmonary resuscitation guide " regulation is that patient's breastbone is sunk 40～50 millimeters.But " dynamics " and " degree of depth " can't convert, so the operator can't know the degree that patient's breastbone sink when pushing at all, and the grasp of compression frequency does not also have " object of reference ", thereby make " operability " of guide restricted greatly.For addressing this problem, some artificial cardio-pulmonary resuscitation depressors have appearred in recent years.As Chinese invention patent ZL200420097782.7 disclosed " cardiac compression recovery indicating device ".This device by Pressure gauge, by pipeline connect air bag, air bag is arranged on handbag, the pointer on the Pressure gauge connects battery cathode by electric wire, an end connecting terminal of buzzer, the other end connects anode, indicator is corresponding with the contact to be formed.Medical personnel put glove and are positioned over patient's chest and push during use, demonstrate the numerical value that manometric indicator is indicated by the air bag effect, when this numerical value reached the desired strength of heart, the contact contacts with indicator connected circuit, buzzer call, it is effective that heart is pushed in expression.The shortcoming of this device is that the contact position of contact and indicator is fixed, and the pressing force that promptly applies is fixed, can not adapt to the patient of various ages and build, can not strictly realize each requirement according to pressing depth.In addition, this device does not have beat indication, can not strictly realize pushing 100 times/minute frequency requirement.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, provide a kind of can pilot operationp person with the amplitude that the frequency requirement of pushing 100 times/minute is exerted pressure and breastbone sink when directly showing the chest compression each time that patient accepts, thereby can reach the cardio-pulmonary resuscitation guidance device by pressure request of up-to-date international cardio-pulmonary resuscitation guide fully to cardiopulmonary resuscitation.
These cardiopulmonary recovery guidance device has the box body of exerting pressure, displacement sensing element, central processing unit, beat generator and battery are installed in box body, wherein, battery joins with central processing unit and beat generator electricity respectively, displacement sensing element and central processing unit A/D input join, the acousto-optic display element that on and off switch is installed on the box body of exerting pressure and is electrically connected with central processing unit D/A outfan.
Operation principle of the present invention is as follows:
These cardiopulmonary recovery guidance device is placed on patient's the breastbone, turn on the power switch, beat generator and central processing unit are started working, and send sound/optical signal by 100 times/minute frequency, and the operator can apply 100 times/minute push action exactly to the patient under the guiding of this signal; The box body of exerting pressure when exerting pressure is the amplitude of pushing in patient's servo-actuated amplitude on one's body, this amplitude then by being installed in the displacement sensing element institute's perception in the box body and passing to central processing unit, shows on the acousto-optic display element on the box body after central processing unit is handled.The operator can apply 40～50 millimeters the amplitude of pushing exactly to the patient under the guidance of this signal.Thereby realize the quantification requirement of the multiple guide of up-to-date international cardiopulmonary.In addition, these cardiopulmonary recovery guidance device adopts microelectronic element to constitute, thereby volume is little, is convenient for carrying.
Can offer the recess that a palm with the people matches at the upper surface of the box body of exerting pressure, with the convenient correct position of exerting pressure of slipping away when fixedly palm prevents to exert pressure.In this case, all acousto-optic display elements should be seated in the next door of recess with convenient observation.
Compared with the aforementioned existing similar products, advantage of the present invention is to use very simple and convenient, and user only needs simple training just can use and can reach fully the quantification requirement of up-to-date international cardio-pulmonary resuscitation guide, can greatly improve the cardiopulmonary resuscitation success rate.And volume is little, is convenient for carrying.Can be widely used in the public and family's occasions such as hospitals at different levels, rural health institute, public transport, big bus, steamer, aircraft, school.Can both reach the patient of all ages and classes, build and to quantize to exert pressure.
Content of the present invention further illustrates with the following Examples, but content of the present invention is not limited only to content related among the embodiment.
