Description
Technical field
The invention belongs to continuous blood purification device, specifically the continuous way CRRT machine capability bascule of a kind of two trippers.
Background technology
The english abbreviation of CRRT (i.e. continuousrenalreplacementtherapy) continuous renal replacement therapy.Have another name called CBP (continuousbloodpurification)；Bedside hemo-filtration.Being adopt 24 hours every days or long-time close to the one of 24 hours, continuous print extracorporeal blood purifies therapy to substitute impaired renal function.
Nineteen ninety-five, in the international CRRT academic conference of the first that San Diego, USA is held, CRRT by formal definition is: all seriality can remove solute, and organ function plays the blood purification technology of supporting function.During World War II, Canadian Murray and Delmore succeeds in developing First artificial kidney machine, and in l946 for clinical treatment renal failure, later blood purification technology is rapidly developed.Blood purification is blood samples of patients to be caused external and passes through a kind of purifier, removes some of which morbid substance purification blood and reaches the purpose for the treatment of disease.It mainly includes hemodialysis, hemofiltration, hemodiafiltration, hemoperfusion, plasmapheresis, immunoadsorption etc..Current blood purification therapy has not been provided purely for treating acute and chronic patients with renal failure, is also widely applied in the rescue of Severe acute disease patient.
CRRT clinical practice target is excess moisture in purged body, purged body intracellular metabolite refuse, poisonous substance, corrects Electrolyte imbalance, it is ensured that nutritional support, promotes graft function and removes various cytokine, inflammatory mediator.Can be used for: various cardiovascular functioies instability, Metabolism or companion's cerebral edema acute and chronic renal failure, and Multiple Organ Dysfunction Syndrome, adult respiratory distress syndrome, crush syndrome, acute necrotizing pancreatitis, chronic heart failure, hepatic encephalopathy, the treatment of medicine and toxic poisoning etc..
At present, it is used mostly the CRRT machine that Bei Lang company of Germany produces or the CRRT machine that Fresenius group of Germany produces clinically, or the CRRT machine of some other brand carries out Continuous Renal Replace Threapy.
CRRT machine is in the course of the work, it is necessary to accurately controlling speed and the amount of turnover cardiopulmonary bypass in patients liquid, the difference of the liquid in-out scale of construction is net ultrafiltration, namely from the moisture content of internal removing.Usual CRRT machine controls to enter the liquid velocity of extracorporeal circulation by displacement liquid/dialysis liquid pump, control the speed of extracorporeal circulation liquid by waste drains pump, carry out the amount of accurate kinetic measurement turnover liquid simultaneously also by the scale within CRRT machine, and feedback regulates displacement liquid/dialysis solution, waste drains pump speed reaches to control the purpose of turnover extracorporeal circulation amount of liquid.
Obviously, turnover fluid balance existing defects is controlled: one is that scale need to often be calibrated by the mode of scale kinetic measurement liquid weight, in use procedure, precision also can be gradually reduced, two is that scale is measured and can only be carried out in resting state, in therapeutic process, the collision of machine being caused, scale cannot work, therefore existing CRRT machine cannot work in mobile environment.
For overcoming use scale to weigh, the defect of CRRT machine cannot be used in mobile environment, someone studies the method adopting flow monitoring to realize the volume control of CRRT machine, and namely dynamic measurement flows into, flows out extracorporeal circulation flow rate of liquid and calculate flow according to sectional area.The method of kinetic measurement flow velocity includes magnetic current method and ultrasonic method.Although this method is it can be avoided that the defect that cannot work under mobile condition of scale, but it is inadequate still to there is precision, the defect that error is big.Instant flow measurement needs the several seconds to measure a flow, namely needs to measure tens times in one minute, then the amount of liquid obtaining in the unit interval that each measurement result added up.Even if therefore single measurement error is only small, but the additive effect of measuring result error necessarily causes that total error is very big many times.For instant flow measurement, although the also kinetic measurement of scale system, but be directly measure to obtain total liquid turnover amount in certain time period, but not pass through the cumulative of repetitive measurement result, therefore it is absent from additive effect. every time.Additionally, micro-bubble and the long-pending change in use of pipe section in liquid all can affect flow measurement precision.
Treating for CRRT, every day, fluid exchange amount was typically in more than 20L, reached as high as more than 100L, and if error is within 1%, the liquid margin of error is 200ml-1000ml, if the treatment absolute error amount of a few days is bigger continuously.And effusion meter control capability balance error is difficult to reach less than 1%.
Existing CRRT machine cannot be useful in the Moveable type vehicles such as aircraft, automobile, train, steamer and carry out CRRT treatment, this just gives and is badly in need of CRRT treatment, and due to the restriction in distance and the vehicles, cannot be carried out CRRT treatment and bring challenge, the injured soldier in such as battlefield can only transport medical treatment base back and rescue and treatment, and patient with severe symptoms cannot rescue enterprising the robbing of ambulance and treat.
Therefore the more convenient use of CRRT machinery requirement, more accurate capacity control device and system.
