Description
Technical field
The present invention relates to a kind of member of blood cleaning equipment, relate in particular to volume-varied balancer, the realization dialysis solution disposes and dewaters from human body in guarantor unit's time dialysate flow.
Background technology
Hemodialysis (HD) is a kind of most important pattern of blood purification treatment, and it is that treatment uremia, acute and chronic renal failure are combined the main therapeutic modality that latter stage, the patient depended on for existence at present.Because the kidney organ of uremic patient has partially or completely lost urinary function, so need carry out hemodialysis, and two of hemodialysis mainly act as: 1) remove vivotoxin or correction acid-base balance by the fixing a certain amount of dialysis solution and the disperse principle of blood in the unit interval; 2) go out excessive moisture by ultrafiltration system ultrafiltration from blood of human body and tissue fluid.
For uremic patient, one time hemodialysis was generally 4～5 hours, need be 120～150L with the dialysis solution quantity of blood exchange, so a large amount of dialysis solution and blood carries out mass exchange, so the unit interval enters the dialysis liquid measure of dialyser and need guarantee to equate from the waste liquid amount that dialyser comes out, otherwise not only do not reach from the purpose of human body dehydration, and it is unbalance to occur amount of liquid easily, and then patient's life is produced dangerous.
Chinese patent ZL 200610054252.8 announced a kind of blood purification on the 3rd with capacitance balance and ultrafiltration apparatus in December in 2008, and the mode that adopts capacity balancer assembly and ultrafiltrate pump to combine is worked.The flow of dialysis solution and waste liquid turnover capacity balancer assembly equates in capacity balancer assembly guarantor unit's time, each electromagnetic valve on the capacity balancer assembly is electrically connected with control circuit respectively, utilizes single-chip microcomputer to be responsible for coordinating the open and close of eight electromagnetic valves in this control circuit.Eight electromagnetic valve alternately open and close, the pressure that utilizes two gear pumps to produce make that the barrier film in each cavity moves to the left or to the right on the capacity balancer assembly, thereby realize the filling and the emptying of each chamber.More than device utilizes pressure monitor to gather pressure signal, and regulates the rotating speed of pump by control circuit, mainly has following deficiency:
1, to finish from human body dehydration must adopt other high-precision ultrafiltrate pump together co-ordination could realize, system complex, reliability is low.
