Problems solved by technology

However, in the actual blood collection process, the hematocrit of most patients is not known to the blood collector, and will only be discovered after the blood collection tube is sent to the laboratory; Too much or too little blood collection, resulting in inaccurate ratio of anticoagulant to blood
At this time, if it is returned and re-collected, it will increase the pain of the patient, the workload of blood collection and the blood collection consumables; if it is directly tested, it will cause obvious errors in the results, which will affect the patient's diagnosis and treatment.
In particular, commercialized disposable vacuum blood collection tubes are now used. 109mmol / L sodium citrate 0.2ml has been added to the tube and the blood collection volume of 1.8ml is stipulated, which brings great inconvenience and difficulty to the blood collection personnel and the laboratory.
In order to solve these problems, many people have proposed many methods, but none of them have achieved obvious results.

Abstract

The invention discloses a disposable blood-coagulating vacuum blood collection tube and belongs to the technical field of medical instruments. The disposable blood-coagulating vacuum blood collectiontube comprises a tube body, wherein a label with scales is arranged on the tube body, a sodium citrate anticoagulant is arranged in the tube body, the concentration of the sodium citrate anticoagulantis 436 mmol / L, and the volume of the sodium citrate anticoagulant is 0.05 ml. By using the tube, the blood sampling amount does not need to be limited, the sample volume and the red blood cell amountcan be quantified, and blood sampling does not need to be conducted again on a sample with obviously abnormal hematocrit. It is verified by use results of 280 patients that detection results are accurate and reliable. Moreover, the tube is easy to produce and simple and convenient to use, can completely replace an original blood collection tube, and has obvious use value and economic benefit.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable coagulation vacuum blood collection tube. Background technique [0002] Coagulation tests require anticoagulated blood samples. According to regulations, the anticoagulant blood sample is composed of 109mmol / L sodium citrate and blood at a ratio of 1:9, and it is required that the anticoagulant and The ratio of blood should be adjusted. However, in the actual blood collection process, the hematocrit of most patients is not known to the blood collector, and will only be discovered after the blood collection tube is sent to the laboratory; Too much or too little blood collection results in an inaccurate ratio of anticoagulant to blood. At this time, if it is returned and re-collected, it will increase the patient's pain, blood collection workload and blood collection consumables; if it is directly tested, it will cause obvious errors in the results, which wi...
