Method and device for automatically detecting sedimentation rate of red blood cells

Abstract

The invention discloses a method for automatically detecting the sedimentation rate of red blood cells. The method comprises the following steps of: setting the sampling time and the sampling times; upon the arrival of the sampling time each time, taking a picture of a blood sample, and accumulating the times for taking photos; obtaining the current liquid level position of the blood sample according to the pictures; comparing the accumulated times for taking pictures with the sampling times; and if the accumulated times for taking pictures is equal to the sampling times, obtaining the sedimentation rate of the red blood cells according to a plurality of the current liquid level positions. According to the method for automatically detecting the sedimentation rate of the red blood cells, which is provided by the embodiment of the invention, a mechanical transmission device is not needed, the mechanical design and software control are simple and feasible, and the computational complexity is low. The invention also discloses a device for automatically detecting the sedimentation rate of the red blood cells.

Description

technical field [0001] The invention relates to the technical field of medical measurement and calculation, in particular to an automatic detection method and device for red blood cell sedimentation rate. Background technique [0002] In medical clinical and medical research, it is often necessary to detect the sedimentation rate of red blood cells in human blood, that is, erythrocyte sedimentation rate. The current national recommended standard for erythrocyte sedimentation measurement is the Weiss method. Add a blood sample with a certain anticoagulant to the Weiss method erythrocyte sedimentation tube, place it on the erythrocyte sedimentation rack, record the initial height scale of the erythrocyte sedimentation, and record the sedimentation after 60 minutes of natural sedimentation The scale can be used to obtain the clinically required erythrocyte sedimentation rate results. [0003] At present, the commonly used automatic erythrocyte sedimentation rate detector basic...

Problems solved by technology

[0003] At present, the commonly used automatic erythrocyte sedimentation rate detector basically adopts infrared light detection method. For example, one method is to install an infrared light sending device and an infrared receiving device that can move up and down on both sides of the blood test tube. During the test, the infrared scanning device moves up and down. , according to the transmission intensity of infrared light to judge the liquid level position of red blood cells, and then calculate the erythrocyte sedimentation rate according to the liquid level position at the beginning and one hour later. This infrared light detection method needs to use a motor and a guide rod to control the up and down movement of the infrared scanning device. , mechanical design and software control are more complex, resulting in higher equipment costs
