Technical field
This utility model relates to technical field of medical instruments, especially a kind of manual type blood self-service purification portable unit.
Background technology
Hemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy, by by internal blood drainage to the most external,
Through one by the dialyser formed without several hollow fibres, the blood electrolyte solution similar to the concentration containing body is empty one by one
Inside and outside core fiber, carry out mass exchange by disperse/convection current, metabolic waste, maintenance electrolyte and the acid-base balance in purged body;
Concurrently disinfect internal too much moisture, and the whole process of the blood recovery through purifying is referred to as hemodialysis.Hemodialysis,
It it is the one of blood purification technology.Utilize semipermeable membrane principle, given up by harmful and unnecessary metabolism various in diffusion, convection cell
Thing and the removal of too much electrolyte are external, reach to purify blood, correct Water-Electrolyte and the purpose of acid-base balance.
Current haemodialysis equipment is heavy-duty machines, is placed in hospital, after patient discharge, controls if also needing to carry out dialysis
Treating, then can very bother, it addition, haemodialysis equipment is fixed at present, volume is excessive, and patient is during going out
Cannot be carried out dialysis treatment, functionally there are some problems.Notification number is the portable autonomous blood of one of CN204618988U
Liquid purifier, provides power by negative pressure pump, by electric suction apparatus blowdown, solves the problems referred to above, but because have employed
Extra negative pressure pump, electric device, manufacturing cost is high, and use process also has to rely on power supply environment, and portability receives very
Big impact.Actually unless urgent hypervelocity purifies and needs, common dialysis procedure slowly, is not required to continue, continually
Fluid injection, blowdown, this device is possible in theory, does not has using value in practice.

Fresh dialysis fluid processed and the replacing ratio of dirty waste liquid, when the waste liquid velocity of discharge is fast, change ratio big, otherwise otherwise then;
Four, the blood extracted out from the patient body blood vessel that enters through dialysis cartridge upper end injects dialysis cartridge, and fresh blood after purification is through thoroughly
Analysis cylinder lower end go out the most defeated time of blood vessel in the patient, complete a complete decontamination cycle;
Five, dialysis solution injects through the liquid injection pipe of liquid storage cylinder upper end, and block is for preventing the dust of external environment condition, germ contamination.
This utility model had the beneficial effect that this utility model reasonable in design, uses integrated design, shared
It is Tong Bu with negative pressure that piston component realizes pressurization, carries out extracorporeal blood purification by semipermeable membrane, it is not necessary to driving means, pure craft
Operation, compact, easy to carry, it is adaptable to emergency procedures and the self-service use of patient, it is that a kind of preferably portable blood is clean
Gasifying device.
