Description
Technical field
The present invention relates to field of medical device, especially a kind of dialysis tube built-in hemodialysis system.
Background technology
Haemodialysis is the principle flowed using solute by the low side of the high lateral concentration of concentration, by blood and dialysis
Both solution of liquid introduce the dialyzer with hollowfibre semi-permeable membrance simultaneously, allow blood to be located at the one of hollowfibre semi-permeable membrance
Side, dialyzate are located at the opposite side of hollowfibre semi-permeable membrance, make the solution of film both sides by disperse and osmosis, to remove people
In in body blood, small molecule toxins, meanwhile, the electrolyte in blood can also reach balance by osmosis, so as to reach
To the purpose for realizing blood purification.
Haemodialysis is also treatment edema disease, acute and chronic Delayed graft function（Uremia）And acute drugs poisoning and agriculture
The common method of medicine poisoning.China has the up to ten million Chronic Renal Failure Patients to need to remain raw with conventional hemodialysis every year at present
Life, and have the trend increased year by year.
Haemodialysis equipment of the prior art, it usually needs the blood of patient is led in vitro, dialysis is utilized in outside
Defeated time patient's body again after device dialysis.Journey of correcting one's mistakes has the problem of following several respects：（1）Blood is in vitro, is likely to result in trouble
Blood volume is drastically reduced or raised in person's body, causes unstable blood pressure to even result in death；（2）Extracorporal dialysis process is typically only capable to hold
Continue several hours, can not continue, carry out haemodialysis for a long time, smoothly for patient；(3) extracorporal dialysis instrument is huge, it is difficult to transports
It is defeated, it is necessary to patient specially is delivered into dialysate chamber, or huge extracorporal dialysis machine transported it is difficult to patient bedside, increase treatment
Degree；(4) instrument price is expensive, up to hundreds thousand of or even millions of.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided one kind dialysis tube built-in haemodialysis
