Continuous blood cleaning equipment with replacement liquid purifier

Abstract

The invention provides an uninterrupted blood purification device with a substitutive fluid purifier. The lower-end tie-in of a blood purifier is connected with an arterial loop pipe, the arterial loop pipe rounds a blood pump after being serially connected with an artery drip pot; the upper-end tie-in of the blood purifier is connected with a vein loop pipe, the vein loop pipe is provided with a third bubble monitor and an occluding clamp after being serially connected with a vein drip pot. Two electronic balances are arranged on the bottom of a main machine; a waste liquid bag is hung on the first electronic balance, a waste liquid loop pipe connected with the waste liquid bag is connected with a lower tie-in on the side face of the blood purifier after rounding a waste liquid pump. A liquid supplement bag is hung on the second electronic balance; a liquid suppliment loop pipe connected with the liquid supplement bag is connected with a lower-end tie-in of an ultra purifier after rounding a liquid feeding pump. The side-face tie-in of the ultra purifier is connected with a liquid inlet of a heater pipe; the liquid outlet of the heater pipe is connected with the artery drip pot or the vein drip pot. The uninterrupted blood purification device of the invention ensures the absolute safety and reliability during the blood filtering treatment, and eliminates the long-term scruple of the clinician on the blood filtering treatment.

Description

technical field [0001] The invention relates to a medical device, in particular to a continuous blood purification device with a replacement fluid purifier, which is used to remove various toxins in patients with acute and chronic renal failure, multiple organ failure or severe pancreatitis. Background technique [0002] Continuous Renal Replacement Therapy (CRRT) is a new blood purification technology that has been greatly developed in the past ten years, and it refers to the slow and continuous removal of water and solutes. As early as 1977, Karmer initially created the continuous arteriovenous hemofiltration (CAVH) technology for the treatment of acute renal failure, and achieved good results. Later, various CRRT modes were derived according to clinical needs, such as arteriovenous slow continuous ultrafiltration (SCUF), continuous venous hemodiafiltration (CVVHDF), continuous venous hemodialysis (CVVHD), etc. CRRT technology adopts a continuous operation method (often f...

Problems solved by technology

However, the replacement fluid produced by the method in 1) generally uses lactate, which has many disadvantages and is basically not used clinically; the method in 2) is used for emergency rescue because the online dialysis filter needs water treatment and cannot be moved casually. It is often not suitable (the general CBP emphasizes that the machine can be moved beside the bed), so the general continuous blood purification treatment basically does not use this method; the third) method is currently the main method used at home and abroad, but due to concerns about operators During the preparation process, the replacement fluid is polluted because the environment cannot meet the aseptic requirements, so it has been questioned all the time
