Abstract

The invention belongs to the technical field of medical equipment, in particular to a continuous blood purification device with a replacement fluid purification function, comprising a main body; a blood filter is fixedly connected to one side of the main body; The middle part of the balance bar is hinged with the main machine through a turning pin; the two ends of the balance bar are symmetrically provided with waste liquid bags and counterweight blocks, and a fixed pulley is rotatably connected to the upper part of the counterweight block in the main machine, and a pull rope is wound around the fixed pulley. One end is fixedly connected with the counterweight block, and the other end is fixedly connected with the rehydration bag; the waste liquid circuit pipe connected on the waste liquid bag bypasses the waste liquid pump and communicates with the middle of the blood filter; the present invention cooperates with the counterweight block and the fixed liquid filter through the balance rod. Pulley, quickly adjust the pumping speed of the waste pump, thereby ensuring the balance of water in the blood.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a continuous blood purification device with a replacement fluid purification function. Background technique [0002] Continuous renal replacement therapy (CRRT) is a new blood purification technology that has achieved great development in the past ten years. It refers to a treatment method that removes water and solutes slowly and continuously. As early as 1977, Karmer initially created continuous arteriovenous hemofiltration (CAVH) technology for the treatment of acute renal failure, and achieved good results, and later derived a variety of CRRT modes according to clinical needs, such as arteriovenous slow continuous ultrafiltration. (SCUF), continuous venous hemodiafiltration (CVVHDF), continuous venous hemodialysis (CVVHD), etc. CRRT technology uses a continuous operation method (often 24 hours); increase blood flow in cardiopulmonary bypass, use high-throughput, bi...
