Description

Technical Field

[0001] The present invention relates to the technical field of erythrocyte sedimentation rate detection, and in particular to an automatic erythrocyte sedimentation rate instrument capable of providing collection assistance and a collection method thereof. Background Art

[0002] An automatic erythrocyte sedimentation meter is an instrument used to measure the sedimentation rate of red blood cells in human blood. The erythrocyte sedimentation rate is the speed at which red blood cells settle to the bottom of the blood within a certain period of time. It is usually used to evaluate the degree of inflammatory response or infection. The automatic erythrocyte sedimentation meter can provide fast and accurate erythrocyte sedimentation values, and compared with traditional manual erythrocyte sedimentation rate measurement methods, it can save time and human resources. It is widely used in medical institutions, laboratories and clinical diagnosis as one of the important indicators for evaluating the degree of inflammation and infection.

[0003] The existing automatic erythrocyte sedimentation meter may have the following problems during use: because it is not equipped with a collection auxiliary function, the patient places the blood on the table during blood collection without any fixing device. The patient is prone to movement due to pain, which may cause blood collection failure or damage the patient's skin. In addition, the best blood collection position is observed by the human eye. If there is a misjudgment, a second injection is required, which will cause secondary pain to the patient and affect the patient's confidence in the medical institution. Summary of the invention
