In vitro circulating coagulating classifier for hematodialysis and coagulating classifying method employing same

Abstract

The invention provides an in vitro circulating coagulating classifier for hematodialysis. The classifier comprises a detection box, a flushing device, a fixing device, a detection unit, a controller and an alarm, wherein the detection box is used for closing a dropper of an in vitro circulating pipeline or a dialyzer therein; the flushing device is arranged next to the detection box, a liquid outlet pipe of the flushing device penetrates through the end portion of the detection box and communicates to the dropper of the in vitro circulating pipeline or the dialyzer, and normal saline is stored in the flushing device; the fixing device is connected to the detection box and the flushing device; the detection unit comprises an infrared emitting structure and an infrared receiving structure, both the infrared emitting structure and the infrared receiving structure are arranged on the inner side wall of the detection box, and the infrared emitting structure and the infrared receiving structure are arranged opposite to each other; both the infrared emitting structure and the infrared receiving structure are connected to the controller; and the alarm is connected to the controller. The in vitro circulating coagulating classifier for hematodialysis, provided by the invention, has the beneficial effect that coagulation of blood in the dialyzer and the in vitro circulating pipeline is automatically classified.

Description

technical field [0001] The invention relates to a hemodialysis device, in particular to a hemodialysis extracorporeal circulation coagulation grader and a blood coagulation classification method using the same. Background technique [0002] With the increase in the number of hemodialysis patients, the demand for dialyzers will increase significantly, and there will be higher requirements for the effect of dialysis. Dialyzer blood coagulation is a common emergency during hemodialysis, and urgent treatment is required, otherwise it will lead to more serious consequences. The causes of dialyzer blood coagulation are: insufficient blood flow, insufficient anticoagulant dosage, hypercoagulable state, and heparin-free dialysis pre-treatment. Insufficient flushing cycle, insufficient arterial puncture needle bleeding, blocked venous needle, reflexed pipeline, frequent machine alarms, blood pump stop, air entering the dialyzer, low ambient temperature, etc. Dialyzer blood coagulati...

Problems solved by technology

In the prior art, in order to detect the occurrence of blood coagulation in time to deal with it and prevent the threat to the patient's life, etc., it is generally determined whether the blood coagulation is serious by artificially observing the above-mentioned blood coagulation performance, but the disadvantages are: due to artificial observation Affected by human subjective factors, there will be a phenomenon that the inspection is not timely, which will threaten the life of the patient; in addition, the artificial judgment of blood coagulation is serious, and each person's judgment standard is different, and there will be a judgment that the blood coagulation is not serious Severe coagulation, severe coagulation is judged as non-severe coagulation, etc. The judgment is not accurate, so the reliability is not high
