The machine can slowly warm the blood of a patient losing vital signs due to coldness and conduct oxygenation properly (as the oxygenation function of drowners is reduced due to the fact that the lung of a drowner is immersed into water) to enable the patient to be resuscitated slowly from 'hibernation', and the effect that the dying is brought back to life can be achieved.
Description
Technical field
The present invention discloses a kind of Portable life resuscitation machine, for sign mistaken diagnosis is the treatment of " dead " patient because cardiac arrest loses one's life, belongs to medical instruments field.
Background technology
In today of scientific and technical high speed development, various professional medical instrument brings Gospel to patient.But, because human knowledge's is gradual, make to also have many patients at present, because can execute without medicine, in other words because treatment loses life not in time.
A concrete example, be exactly drowning person because be immersed in for a long time in cold water, the body temperature of health usually can be reduced to less than 20 degree, and heart also may stop jumping.When these drowning persons are salvaged come up after, traditional medical science viewpoint can mistaken diagnosis be " dead " because they do not have vital sign.But the report in recent international is verified, the patient of these " dead ", if in addition suitable treatment, may bring back to life completely, and because treatment in time, patient also can not because of cardiac arrest damaged brain.
Modern medicine study finds, when the body temperature of human body drops to enough low, people's cognition enters a kind of " hibernation " state being similar to animal.At this moment the energy consumption of human body and oxygen consumption have all dropped to low-down level, so be often misdiagnosed as in default of vital sign " dead ".In this case, if slowly heat to blood, and suitable oxygenate (drowning person reduces Oxygenation function because of pulmonary's immersion), patient just can be made slowly to recover from " hibernation " and to come, " coming back to life ".
Be " heart-lung machine " with the akin Medical Instruments of the present invention, it to flow into outside the venous blood lead body of heart, after carrying out oxygen and carbon dioxide exchange, regulating through temperature and filter, and the device that in defeated ex vivo, the life of tremulous pulse is supported.But the widely used cabinet type heart-lung machine in Hospitals at Present operation on heart room has volume large, and weight is large, needs the shortcoming of external power supply.Therefore, this heart-lung machine can not use without under external power supply condition out of doors, also cannot on ambulance or in use with an army in wartime.
In addition, the most use traffic meter of these cabinet type heart-lung machines controls rotating speed, and its shortcoming is complex structure, is unfavorable for the long steady running of blood pump, operation inconvenience.Experiment proves, when driving the blood pump of blood flow to determine, if motor speed is stable and accurate, so computer just can calculate flow according to rotating speed automatically, thus can not use traffic meter.
Summary of the invention
The invention provides a kind of Portable life resuscitation machine, is one portable life recovery medical assistance instrument, is be ambulance specially, dustoff design, has the features such as structure is simple, easy to use, energy consumption is low.
a kind of Portable life resuscitation machine disclosed by the invention, its technical solution is as follows:
Power supply device composition is taken into account primarily of suction pump, Temp variable vessel, oxygenator, blood cleaning filter, delivery pump, warmer, control circuit system (central processing unit), display and operation keyboard, oxygen air mixture control, oxygen air mass flow; Wherein,
--suction pump and Temp variable vessel, oxygenator, blood clear up filter and delivery pump is linked in sequence, blood is drawn from vein blood vessel, imports in Temp variable vessel;
--Temp variable vessel is slowly heated to blood, inputs oxygenator after carrying out temperature adjustment to blood;
--oxygenator is connected with oxygen air mixture control, and the exchange of carrying the blood of coming to carry out oxygen and carbon dioxide to Temp variable vessel realizes the foster conjunction of blood, oxygen mass air flow sensor display oxygen and air flow separately;
--blood cleaning filter is cleared up and filtration treatment the blood after oxygenate;
--delivery pump returns the blood after peroxo, cleaning and is passed in tremulous pulse;
--warmer produces the water regulating temperature, is supplied to Temp variable vessel and carries out alternating temperature to blood;
--control circuit system (central processing unit) is connected with suction pump, delivery pump, with suitable rotating speed smooth operation, makes blood flow out from vein blood vessel and finally backflow to tremulous pulse.
Described suction pump, delivery pump all adopt rotor pump structure, and the two ends up and down of the pump housing are provided with flow export and inflow entrance; Flow export is horn mouth shape, and its inwall is provided with resistance and revolves muscle; Flow export is communicated with pump chamber by " L " type deceleration tube; Armature spindle to be connected with motor and control circuit in pump chamber by bearing holder device, and armature spindle is distributed with helical blade.
Impeller pump feature of the present invention is: rotor Direct driver blood flow, drive the energy consumption of blood flow relatively little, thus small machine can be selected to promote the flowing of blood, make Portable life resuscitation machine can limited battery-operated under, realize running for a long time as much as possible.
work process of the present invention is as follows:
Sue and labour the blood flow of patient mainly by two impeller pumps--namely suction pump and delivery pump have cooperated; Suction pump is drawn blood from vein blood vessel; Delivery pump returns the blood after peroxidating cleaning and is passed to tremulous pulse.Two impeller pumps, under the regulating and controlling of control circuit system (central processing unit), with steady rotation speed operation, make blood flow out from vein blood vessel and finally backflow to tremulous pulse; Temp variable vessel carries out temperature adjustment to blood, is critical function parts of Portable life resuscitation machine.It can as required, slowly be heated to blood, allows life entity recover.The foster conjunction of blood is completed by oxygenator, and oxygenator carries out the exchange of oxygen and carbon dioxide to blood.Blood cleaning filter is cleared up and filtration treatment blood.
good effect of the present invention is:
The device of blood samples of patients of suing and labouring is driven to adopt rotor pump structure, by controlling to make its motor speed accurate, make full use of principle of hydrodynamics, blood is made to obtain power in the environment of smoothness, reduce the impact brought to blood because of rotor turns as far as possible, reduce the damage to blood, reduce thrombotic probability." L " type design of impeller pump flow export, structure is revolved in resistance, and hydraulic pressure converts, and the layout of fluid-dynamic design rotor blade, can reduce the disturbance of blood, the formation of anti-tampon.The present invention can to because cold and the blood of the sign patient that loses one's life slowly is heated, and suitable oxygenate (drowning person reduces Oxygenation function because of pulmonary's immersion), patient just can be made slowly to recover from " hibernation " and to come, " coming back to life ".Save those are misdiagnosed as " dead " person life because of cardiac arrest.
