Description
Technical field
This utility model relates to technical field of medical equipment, particularly relates to a kind of haemodialysis equipment.
Background technology
The mainstream therapies releasing edema at present mainly includes two kinds: 1. drug diuresis: uses medicine to make patient's hydrouria, thus is excreted by the approach of " blood-kidney-urine " by internal excessive moisture；2. extracorporeal blood dialysis: extracted out by the blood in patient body, through the filtration of extracorporal dialysis instrument, filtered by the excessive moisture in blood, the remaining blood through " concentration " feeds back internal again, thus reaches to release the purpose of edema.
Hemodialysis is also to treat acute and chronic Delayed graft function (uremia) and acute drugs poisoning and the common method of pesticide intoxication.China has up to ten million Chronic Renal Failure Patients to need to sustain life with conventional hemodialysis (CHD) every year at present, and has the trend increased year by year.Hemodialysis principle: dialysis refers to that the solution of semipermeable membrane both sides is by disperse, infiltration and Ultrafiltration, i.e. solute is flowed to the side that concentration is low by the side that concentration is high, and the process flowed to the side that osmotic pressure is high in the side that hydrone is forced down by infiltration, it is finally reached dynamic equilibrium.Hemodialysis reaches therapeutic purposes by the solution disperse between blood and dialysis solution and ultrafiltration.
The therapy of prior art is primarily present following shortcoming: 1. drug diuresis method: shortcoming be use medicine in a large number after toxic and side effects and drug resistance phenomenon easily occur, or be often associated with renal failure because of critical patient, blocked the diuresis approach of appeal, caused diuretic effect the best；2. extracorporeal blood dialysis process: (1) is external owing to be extracted out by blood, then feeds back in patient body, period can cause patient body in blood volume drastically reduce or raise, cause unstable blood pressure to even result in death；(2) extracorporal dialysis process is typically only capable to the most several hours, it is impossible to lasting, give excessive moisture for a long time, smoothly for patient；(3) extracorporal dialysis instrument is huge, it is difficult to transport, needs the special dialysate chamber that patient is delivered to, or by huge extracorporal dialysis machine transport to patient bedside, increases treatment difficulty；(4) instrument price is expensive, reaches hundreds thousand of the most millions of.
Utility model content
The purpose of this utility model is: for the problem of above-mentioned existence, it is provided that a kind of haemodialysis equipment.Dialysis tubing in this haemodialysis equipment is placed in human body in tremulous pulse when dialysis, the most in vivo blood vessel completes hemodialysis, and external carry out hemodialysis through machine again without blood is extracted out, thus on human blood-pressure without impact, safety more more economical than external hemodialysis and wound are little.
