Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of contactless Westergren method blood sedimentation detection device. BACKGROUND

[0002] Blood sedimentation refers to the sedimentation rate of red blood cells under certain conditions within a unit of time, usually expressed by the distance of red blood cells sinking at the end of the first hour. The determination method of blood sedimentation is various, among which the Westergren blood sedimentation detection method is widely used due to its simple operation and stable results, and the normal value range is generally 0-15mm / h for men and 0-20mm / h for women. Blood sedimentation is a frequently detected index in clinical practice, and the main reasons for its physiological increase include physiological anemia, gradual increase of fibrinogen, etc. The pathological increase includes various acute and chronic inflammation, tissue damage and necrosis, malignant tumor, hyperglobulinemia caused by various reasons, anemia, etc.

[0003] The operation steps of the Westergren blood sedimentation detection method are as follows: (1) blood collection: venous blood is used for blood sedimentation test, and under ideal conditions, the patient should be in a fasting state or the time interval between diet and detection should be far enough; (2) anticoagulation treatment: 3.8% sodium citrate is usually used as an anticoagulant, and the collected blood is mixed with the anticoagulant for anticoagulation treatment to avoid blood clotting; (3) inverted mixing: the blood with anticoagulant is inverted and mixed, usually by twisting the blood vessel several times after sealing the closed end to disperse the blood fully; (4) vertical filling of blood sedimentation tube: a clean and oil-free micropipette is used to suck the anticoagulated blood, and then the blood is slowly added to the blood sedimentation tube, ensuring that the blood forms a blood column with a standard height in the blood sedimentation tube; (5) placing on a vertical sedimentation rack: the blood sedimentation tube is placed on a vertical sedimentation rack, the temperature is controlled at 18-25℃, and the vertical sedimentation rack is kept horizontal and is prevented from being shaken or impacted, so as to ensure that the blood can freely sink within a certain time; (6) counting time: the counting time is started, usually set as 60 minutes, during which the red blood cells in the blood will gradually sink to form a layered structure; (7) observing and calculating the blood sedimentation value: after the counting time ends, the height of the red blood cell layer in the blood sedimentation tube is observed, usually recorded in millimeters, which is the blood sedimentation value.

[0004] Currently, there is no special detection device for the Westergren blood sedimentation detection method, and usually a ear ball is connected to a pipette to suck 2ml of blood into the pipette, the upper and lower ends of the pipette are blocked, and then the pipette is vertically placed on a rack, the initial height of the blood page is recorded, and after 1 hour, the height of the red blood cell liquid surface is recorded again.
