Description

The supporting haemodialysis equipment of a kind of improved haemodialysis control unit

Technical field

This utility model relates to a kind of field of medical, specifically is the supporting haemodialysis equipment of a kind of improved haemodialysis control unit.

Background technology

Hemodialysis is the common method for the treatment of acute and chronic kidney merit depleted (uremia) and acute drugs poisoning and pesticide intoxication.China has up to ten million Chronic Renal Failure Patients to sustain life with conventional hemodialysis (CHD) every year at present, and the trend of increasing year by year is arranged.

The hemodialysis principle: dialysis refers to that the solution of semipermeable membrane both sides is by disperse, infiltration and Ultrafiltration, be that solute is by the high low side flow of a side direction concentration of concentration, and the process of the high side flow of the side direction osmotic pressure that hydrone is forced down by infiltration finally reaches dynamic equilibrium.Hemodialysis reaches therapeutic purposes by solution disperse and the ultrafiltration between blood and the dialysis solution.Therefore dialysis procedure namely solute carry out disperse and filtration process.Hemodialysis comprises the movement of solute and the movement of water, be that blood borrows semipermeable membrane to contact in dialyser (artificial kidney) with dialysis solution and Concentraton gradient carries out mass exchange, metabolic waste in the blood and too much electrolyte are moved to dialysis solution, and the calcium ion in the dialysis solution, base etc. are mobile in the blood.Thereby the metabolic waste in the removing blood samples of patients and poisonous substance; Adjust fluid and electrolyte balance; Adjust acid-base balance.

Haemodialysis control unit roughly can be divided into blood monitoring warning system and dialysis solution feed system two parts.Blood monitoring warning system comprises blood pump, heparin pump, the monitoring of sound pulse pressure and air monitering etc.; The dialysis solution feed system comprises that temperature control system, liquid mixing system, off gas system, monitored conductivity system, ultrafiltration monitoring and the monitoring of leakage blood etc. partly form.Its operation principle is: dialysis is mixed with qualified dialysis solution with concentrated solution and water for dialysis through the dialysis solution feed system, and by hemodialyzer, the patient blood of drawing with blood monitoring warning system carries out solute dispersion, infiltration and Ultrafiltration; Patient blood after the effect returns in the patient body by blood monitoring warning system, and the liquid after dialysis is used is simultaneously discharged by the dialysis solution feed system as waste liquid; Constantly move in circles, thereby reach the purpose for the treatment of, finish whole dialysis procedure.

Dialyser is all being reused in many ground, the world at present, to reduce cost, reduces medical expense, and reduces dialyser and use first syndromic generation.Hemodialysis must be set up extracorporeal circulation with dialyser, blood vessel, and sets up the dialysis solution pipeline with the dialysis solution pipeline, and dialyser is the key equipment of hemodialysis and the consumption equipment of Main Economic expenditure.The haemodialysis equipment complex structure of using in hospital at present and depend on the water source and power supply when cutting off the water or having a power failure suddenly, can bring great impact to ongoing hemodialysis, has increased patient's misery.In addition use at present widely hemodialysis normally to use a dialyser and the outer circulation of artery and vein bloody path pipe constituting body, after dialyser is used several times, because its curative effect descends, the dialyser that namely goes out of use and more renew, but dialyser capacity and the decrease in efficiency about about 20% of this moment, also have quite a few remaining function not to be utilized and to discard, if the residue function sum of two discarded dialysers can be taken full advantage of again, then can improve dialytic efficiency, alleviate its financial burden and hospital economy expenditure.

The utility model content

The purpose of this utility model is to provide a kind of haemodialysis equipment simple in structure at this, improves dialytic efficiency, alleviates its financial burden and economic expenditure.

This utility model is to realize like this, construct the supporting haemodialysis equipment of a kind of improved haemodialysis control unit, it is characterized in that: include ductus arteriosus, new dialyser, discarded dialyser, series connection blood vessel and venous duct, the bloody path pipeline that this haemodialysis equipment is corresponding is by ductus arteriosus, venous duct, the blood chamber 102a of these two dialysers and 103a and series connection blood vessel are composed in series, the blood chamber arterial end that described ductus arteriosus is corresponding with described new dialyser connects, the vein port that described discarded dialyser is corresponding is connected with described venous duct, two dialysate hole 106a of described new its side of dialyser, the upper corresponding dialysis solution conduit A that connects of 106 b, dialysis solution conduit B, dialysis solution conduit A, be respectively arranged with dialyzate bag A on the dialysis solution conduit B, dialyzate bag B, two dialysate hole 109a of described discarded its side of dialyser, be connected with dialysis solution conduit C on the 109b, dialysis solution conduit D, dialysis solution conduit C, be respectively arranged with dialyzate bag C on the dialysis solution conduit D, dialyzate bag D.

The beneficial effects of the utility model are: this utility model provides a kind of haemodialysis equipment at this, improve dialytic efficiency, simple in structure, alleviate its financial burden and economic expenditure.New dialyser described in this utility model, discarded dialyser are provided with two dialyzate bags, and dialysis solution replaces repeatedly, regularly changes fresh dialysis solution, the liquid pump of need not dialysing.Make the dialyser multiplexing number of times increase many times by improvement, because utilizing simultaneously two dough-making powder of preparing in the original plan the residue function of discarded dialyser not lessen the curative effect, both improved hemodialysis efficient, alleviated again patient's financial burden, reduced again the economy expenditure of hospital, can greatly improve the Social benefit and economic benefit of hemodialysis, use is worth promoting.
