Online peritoneal dialysis unit and preparation method

Abstract

The invention discloses an online peritoneal dialysis unit and preparation method which integrates computer automation control technique, antiosmosis water processing technology and peritoneal dialysis solution concentrating technology. The unit can online prepare peritoneal dialysis solution equal to or more than 30L in 10-20 hour curing process with a peritoneal dialysis solution preparing speed which is equal to or more than 200ml / min, which meets the requirement that the clinic care exchange capacity reaches 50ml / min; automatically completes exchange operating process more than 15-18 times, solves the defects that using the current CAPD technology to realize large-volume exchange is difficult to operate frequently and the APD equipment does not have the function of 30L-36L large-volume exchange function, and provides technical supports for realizing the KT / V value of most patients to be equal to or more than 2.1, realizing the Ccr of more than 70 percent of patients to be equal to or more than 60ml / 1.73 square meters, realizing the elimination rate of carbamide to be more than 12ml / min, and improves the survive rate of the patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an on-line peritoneal dialysis device and a preparation method. Background technique [0002] Peritoneal dialysis is one of the effective methods of renal function replacement therapy for patients with "renal failure (uremia)" confirmed by the medical community. The current peritoneal dialysis treatment basically adopts the treatment method of patients at home: CAPD method; or the method of replacing manual operation treatment by machine: APD method. [0003] No matter which method is CAPD / APD, peritoneal dialysis is used in a 2000ml plastic bag configured by the pharmaceutical factory according to a fixed formula. The treatment method is: first, 2000ml / bag of peritoneal dialysis fluid is infused into the peritoneal cavity through the catheter channel left in the peritoneal cavity, the peritoneal dialysis fluid stays in the peritoneal cavity for 3-4 hours to exchange with the huma...

Problems solved by technology

[0010] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide the fusion of computer automatic control technology, reverse osmosis water treatment technology and concentrated peritoneal dialysis solution technology. During the 10-12 hour treatment process, the device can prepare ≥30L peritoneal dialysate online. Dialysate, the dialysate preparation rate is ≥200ml / min, which meets the requirement of 50ml / min for clinical treatment; automatically completes more than 15-18 times of exchange operations, and solves the problem of frequent large-capacity exchange using the current CAPD technology Difficult to operate and APD equipment does not have the shortcomings of 30L-36L large-capacity exchange function, in order to achieve KT / V value ≥ 2.1 for most patients, Ccr ≥ 60ml / 1.73m for more than 70% of patients 2 , the clearance rate of urea>12ml / min, improving the survival rate of patients provides a technical guarantee
