Abstract

The embodiment of the invention discloses a full-automatic regional citrate anticoagulation (RCA) machine which includes a sampling portion, a sample-injection portion, a test analysis portion, an administration portion, and a program control portion. The sampling portion extracts a blood sample on line and in real time and sends the blood sample to a blood sample storage purifier for storage and purification. The sample-injection portion conveys the blood sample in blood storage purifier through a sample injection tube to a sample-loading slot. The test analysis portion conveys the blood sample through a sample suction tube to an analysis meter for blood sample test and analysis. The sampling portion, the sample-injection portion, the test analysis portion and the administration portion are connected to the program control portion. The program control portion controls the sampling portion, the sample-injection portion and the test analysis portion to work according to an internal set program, and sends an instruction to the administration portion according to the data result obtained from the test analysis portion. The technical problems that manual operation and operation steps are tedious and time-consuming, the time for adjusting the administration dosage is delayed, and the charge is expensive in the RCA method in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fully automatic citric acid partial anticoagulant machine. Background technique [0002] Continuous Renal Replacement Therapy (CRRT), also known as Continuous Blood Purification (CBP), is a new method of blood purification. In 1995, the First International Conference on Continuous Renal Replacement Therapy stipulated that a continuous blood purification therapy for 24 hours a day or close to 24 hours to replace the purification method of damaged kidney function is called continuous renal replacement therapy. Continuous renal replacement therapy includes continuous arteriovenous, venous hemofiltration (CAVH, CVVH), continuous arteriovenous, venous hemodialysis (CAVDH, CVVDH), continuous arteriovenous, venous hemodiafiltration (CAVHDF , CVVHDF) and other modes. [0003] Hemodialysis is to extract the blood out of the body, pass through the osmotic membrane of the hemodi...
