To adapt to the working environment of hospital, we use music alarm, power off whenever start, conversion frequency or suddenly, stop
During machine, Melodious musical sound in machine, to remind medical personnel to note in time.
To grasp rescue time, we devise digital timing clock 17.The clock " can be reset " at any time, can be with work
" pause " error<=1 second/day, is single or cumulative timing, and the work such as record, charge offers convenience.
5. pressing, breathing can both be carried out in proportion simultaneously, also can individually it carry out on demand
It is correct to carry out closed cardiac massage and intersection for the patient of a small number of cardiac arrests, breathing stopping or hypoventilation
To exhaust, patient is set to keep the blood circulation and enough oxygenation of certain level, this has ten for saving patient vitals
Divide important meaning.
The utility model collects Worm Wheel System, gear drive and clutch 6 in a transfer gear box 5, presses, exhales
Inhale partable.Often press four times, completion is once forced to breathing, and strictly can synchronously be carried out in this ratio.This is manually to grasp
When making, what unskilled person was unable to reach.
The patient of stopping or hypoventilation is not stoped jumping and breathed for heart, as long as the clutch handle of massage section is dialled
To " stopping " one end, cardio-pulmonary resuscitation machine is just into a lung ventilator, so as to reduce vibrations and noise.
In addition, this machine also has certain curative effect to local pain massage.It can be seen that, CPR can be improved with a tractor serves several purposes
Operating efficiency.
6. mitigate the working strength of medical personnel
At present, still using artificial operation, (both hands are pressed, mouth to mouth many small-middle hospitals (especially in rural area) of China
Breathing) method give emergency treatment to a patient.Though the big-and-middle-sized hospital in part has medicine or apparatus (such as pacemaker, Sirecard, respirator etc.),
But it is still reactionless after above-mentioned measure is taken, it need to carry out still needing to use electronic resuscitating machine during long-time artificial resuscitation.Because people's
Energy is limited, be with the repeated multiple times pressing of tens kilograms of power, and medical personnel are easily tired.It is multiple using the utility model electrodynamic type
Soviet Union's machine, one meets promptly rescue, only needs a people soon can just be worked exactly again with selected frequency, strength, tidal volume stabilization,
