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-type life resuscitating machine, for the sign mistaken diagnosis belongs to medical instruments field for " dead " patient's treatment because cardiac arrest loses one's life.
Background technology
In today of scientific and technical high speed development, various professional medical instruments have brought Gospel to the patient.But, because the human knowledge's is gradual, making to also have many patients at present, can not execute because there is medicine, lost life in other words because treatment is untimely.
A concrete example is exactly the drowning person because be immersed in for a long time in the cold water, and the body temperature of health usually can be reduced to below 20 degree, and heart also may stop to jump.After these drowning persons were salvaged, traditional medical science viewpoint can mistaken diagnosis not be " dead " because they do not have vital sign.But the report on the recent international is verified, the patient of these " dead ", if in addition suitable treatment may bring back to life fully, and because treatment in time, patient can not damage brain because of cardiac arrest yet.
Modern medicine study finds, when the body temperature of human body drops to when enough low, people's cognition enters a kind of " hibernation " state that is similar to animal.At this moment the energy consumption of human body and oxygen consumption has all dropped to low-down level, is " dead " so tend in default of vital sign by mistaken diagnosis.In this case, if slowly heat for blood, and suitable oxygenate (drowning person has reduced the oxygenate function because of pulmonary's immersion), patient is slowly recovered from " hibernation " come " coming back to life ".
With the akin Medical Instruments of the present invention be " heart-lung machine ", it is will flow into outside the venous blood lead body of heart, carries out oxygen and carbon dioxide exchange, through thermoregulation with after filtering, the device that the life of tremulous pulse is supported in the defeated ex vivo.But hospital's widely used cabinet type heart-lung machine in operation on heart chamber has volume big at present, and weight is big, needs the shortcoming of external power supply.Therefore, this heart-lung machine can have out of doors under the external power supply condition and uses, also can't be on ambulance or with an army use the in wartime.
In addition, the most use traffic meter of these cabinet type heart-lung machines is controlled rotating speed, and its shortcoming is complex structure, is unfavorable for the long steady running of blood pump, operation inconvenience.Experiment showed, that accurately, computer just can calculate flow automatically according to rotating speed so if motor speed is stable when the blood pump that drives blood flow is determined, thereby use traffic meter not.
Summary of the invention
The invention provides a kind of portable-type life resuscitating machine, be a kind of portable life recovery medical assistance instrument, is to be ambulance specially, the dustoff design, have characteristics such as simple in structure, easy to use, that energy consumption is low.
A kind of portable-type life resuscitating machine disclosed by the invention, its technical solution is as follows:
Mainly take into account power supply device and form by 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 cleaning filter and delivery pump are linked in sequence, and blood is drawn from vein blood vessel, import in the Temp variable vessel;
--Temp variable vessel is slowly heated to blood, and blood is carried out importing oxygenator behind the thermoregulation;
--oxygenator is connected with oxygen air mixture control, and exchange realization the foster of blood that Temp variable vessel carries the blood of coming to carry out oxygen and carbon dioxide closed, and the oxygen mass air flow sensor shows oxygen and air flow separately;
--the blood of blood cleaning filter after to oxygenate is made cleaning and filtration treatment;
--delivery pump returns the blood after peroxo, cleaning and is passed in the tremulous pulse;
--warmer produces the water of regulating temperature, offers Temp variable vessel blood is carried out alternating temperature;
--control circuit system (central processing unit) is connected with suction pump, delivery pump, with suitable rotating speed smooth operation, blood is flowed out also from vein blood vessel 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 the 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 is connected in pump chamber and with motor and control circuit by bearing holder device, is distributed with helical blade on the armature spindle.
Impeller pump characteristics of the present invention are: rotor directly drives blood flow, the energy consumption that drives blood flow is less relatively, thereby can select for use small machine to promote flowing of blood, make portable-type life recovery function limited battery-operated down, realize running for a long time as much as possible.
Work process of the present invention is as follows:
Sue and labour patient's blood flow mainly by two impeller pumps--be that the cooperation of suction pump and delivery pump is finished; Suction pump is drawn blood from vein blood vessel; Delivery pump returns the blood after the peroxidating cleaning and is passed to tremulous pulse.Two impeller pumps with steady rotation speed operation, make blood flow out also from vein blood vessel and finally backflow to tremulous pulse under the regulating and controlling of control circuit system (central processing unit); Temp variable vessel carries out thermoregulation to blood, is critical function parts of portable-type life resuscitating machine.It can slowly be heated to blood as required, allows life entity recover.Foster the closing by oxygenator of blood finished, and oxygenator carries out the exchange of oxygen and carbon dioxide to blood.Blood cleaning filter is made cleaning and filtration treatment to blood.
Good effect of the present invention is:
The sue and labour device of blood samples of patients of driving adopts rotor pump structure, make its motor speed accurate by control, take full advantage of principle of hydrodynamics, make blood in the environment of smoothness, obtain power, reduce as far as possible because rotor rotates the influence that brings to blood, reduce the damage to blood, reduced thrombotic probability." L " type design of impeller pump flow export, structure is revolved in resistance, the hydraulic pressure conversion, the layout of hydrodynamics design rotor blade can reduce the disturbance of blood, the formation of anti-tampon.The present invention can be to because cold and the sign patient's that loses one's life blood is slowly heated, and suitable oxygenate (drowning person has reduced the oxygenate function because of pulmonary's immersion), patient slowly recovered from " hibernation " come " coming back to life ".Having saved those because of cardiac arrest is " dead " person's life by mistaken diagnosis.
