Description
The present invention relates to a kind of armarium, particularly a kind of multifunctional easily-transportable artificial kidney.The present invention is fit to medical institutions at different levels and is used to give treatment to acute renal failure, chronic renal failure, each phase uremia, multiple organ dysfunction syndrome companion renal failure, severe pancreatitis, be fit to continue the various diseases of kidney alternative medicine (CRRT) treatment, poisonous substance, drug intoxication etc.
The conventional artificial kidney machine (haemodialysis control unit) of existing background technology is used to give treatment to acute renal failure at large, chronic renal failure, each phase uremia, and design is fairly perfect, large-scale haemodialysis control unit designs general computerization, capacity monitor, basic functions such as hydrocarbonate dialysis all possess.But, the ubiquitous shortcoming of conventional artificial kidney machine is: [1] relies on the water source, conventional hemodialysis (CHD) machine or hemodialysis filter must be by reverse osmosis water treatment machines in treatment, continuously reverse osmosis water is delivered to haemodialysis control unit by high-pressure water pipe, automatic mixing system by haemodialysis control unit, A, B concentrated solution are mixed with and can carry out the treatment of hemodialysis or hemodiafiltration through the dialysis solution of blood dialyser or transfusion filters with reverse osmosis water pari passu.[2] can not move temporarily, conventional artificial kidney machine is large-scale haemodialysis control unit or hemodialysis filter, owing to rely on the water source, be unable to do without the reverse osmosis water blood processor, so be unable to do without Blood Purification Center or Laminar Airflow Room in the treatment, can not move that patient's bed is other to carry out hemodialysis or hemodiafiltration treatment according to patient's the state of an illness.[3] can not carry out the other CRRT treatment of bed, the other CRRT content of bed comprises: continuous arterio venous hemofiltration (CAVH), continuously silently-venous hemofiltration (CVVH), continuous arterio venous hemofiltration dialysis (CAVHD), vein-venous hemofiltration dialysis (CVVHD) continuously, continuously slow hemofiltration (CSHF), continuously slow blood ultrafiltration (CSHU).These contents of CRRT treatment are because the inconvenience of conventional hemodialysis (CHD) machine is moved and all is difficult to carry out.[4] can not carry the rescue of paying a home visit, because the conventional hemodialysis (CHD) machine relies on the water source, can not carry the treatment patient that pays a home visit according to emergency arbitrarily, the section office that can not be in hospital as required haemodialysis control unit be moved the patient place carry out emergency aid and treatment.[5] can not carry out plasmapheresis, no matter which kind of type of conventional hemodialysis (CHD) machine has only one or two blood pump, present design all can not be carried out the membrane type blood plasma replacement therapy.[6] manufacturing cost height, the conventional hemodialysis (CHD) machine is an automatic mixing pump formula owing to the dialysis solution dosing, the capacity monitor balance cavity type, its electronics, Machine Design are all very complicated, cause the manufacturing cost height, and selling price is difficult to drop to lower level.[7] waste water resource, the water source that first conventional hemodialysis (CHD) machine is used after all being handled by the reverse osmosis water blood processor, when the reverse osmosis water blood processor is used tap water in the processing city, will have the tap water of a great deal of to be dumped simultaneously; It two is the used dialysis solution of conventional hemodialysis (CHD) machine, promptly drained into sewer by dialyser or filter once to drain, to use the water source when before treating, preparing, per minute is 500 milliliters behind every haemodialysis control unit begin treatment, per hour 30,000 milliliters, treatment time was generally 4～5 hours, that is to say that each treatment wants water 12～150,000 milliliter dialysis solution; Add that the water that equal quantities dumps from water treatment facilities promptly reaches 24～300,000 ml waters.For the per capita like this water resources quantity of China is very disadvantageous for world occupancy volume per person's 1/6 national state only.[8] capacity ultrafiltration error higher, the current import conventional hemodialysis (CHD) machine of probability that is out of order more greatly adopts the two chamber system of capacitance balance mostly.Because two chamber balance sysmtes are controlled with the form of electric mechanical automatically by 8 electronics valves, as long as there is an electronics machine valve to be out of order, automatically capacity control system just can accurately not controlled capacitance balance, so volume control just can not be very accurate, and out of order chance is higher.Following table compares a kind of medical multifunctional portable artificial kidney and conventional hemodialysis (CHD) machine and existing C RRT machine work one.
