发明名称 Device and methods for perfusing peritoneal dialysing fluid
摘要 <p>The present invention relates to an instrument for continuous recirculation of peritoneal dialysate to infuse and drain out the dialysate automatically through catheter(s) implanted in peritoneal cavity of human body, comprising (a) prefilter, (b) primary filter comprising semipermeable membrane having maximum permeable molecule of 30,000 dalton, (c) pump for lowering the outside pressure of the primary filter (b) relative to the inside pressure, (d) secondary filter comprising semipermeable membrane having maximum permeable molecule of 5,000 dalton, (e) pump for raising the pressure of supplemental liquor line relative to the inside of the secondary filter line, and a recirculation method of dialysate using the above-mentioned instrument. The present invention aims at providing a recirculation instrument for reusing protein which is permeated out from patient's body, as an osmotic agent in peritoneal dialysate, for maintaining recirculating line disinfect, and for improving ultrafiltration rate and clearance of uremic toxin. By using above-mentioned technology, the present invention enables (1) to minimize the contact with atmosphere and foreign matters, for preventing protein's denaturing, (II) to minimize plugging the semipermeable membrane on the recirculation line and (III) to prevent perfectly the invasion of bacteria and endotoxin from outside. <IMAGE></p>
