Erythrocyte sedimentation rate analyzer

The erythrocyte sedimentation rate analyzer is a medical detection instrument based on the Wei's method. The instrument uses infrared detection technology or other photoelectric technology to scan the interface position between red blood cells and plasma at regular intervals according to the changes in plasma turbidity during the sinking process of red blood cells. It dynamically records the entire erythrocyte sedimentation rate process, and the data is processed by a computer to obtain the detection results.

Erythrocyte sedimentation rate analyzerIntroduction:

1. Test conformity rate: Compared with the results of the Weibull method, the conformity rate is not less than 90.0%;

2. Testing repeatability: (0-10) mm/h The standard deviation of the results from the sample testing is not greater than 1.5mm/h;

The coefficient of variation for samples larger than 10mm/h shall not exceed 15%;

Consistency of 4-channel detection: (0-10) mm/h The standard deviation of the results obtained from sample testing is not greater than 1.5mm/h;

The coefficient of variation for samples with a speed greater than 10mm/h shall not exceed 15%;

6. Accuracy of chassis temperature measurement: within the range of 10 ℃ -30 ℃, the deviation does not exceed ± 2.5 ℃;

7. Instrument reading resolution: ± 0.1mm (Wei's method result ± 1mm);

Erythrocyte sedimentation rate analyzerFunctional requirements:

1. Sample loading method: Randomly insert sample grade and conduct testing at any time;

2. Result output: Display and print the sample number (serial number), Weibull's method test results and the entire process erythrocyte sedimentation rate curve, detection time and temperature; When the detection time is 60 minutes, the Katz index can be automatically calculated, displayed, and printed;

The instrument has the function of selecting environmental temperature compensation. When selecting this function, the detection results at room temperature of 15 ℃ -30 ℃ can be corrected to the value at 18 ℃ according to the erythrocyte sedimentation rate correction table;

4SHS-2000 can store test results for no less than 150 samples, including sample number (serial number), erythrocyte sedimentation rate value, and dynamics; Curve;

SHS-3000 can store test results for no less than 260 samples, including sample number (serial number), erythrocyte sedimentation rate value, and dynamic curve;

5. It has a power-off protection function, which automatically saves the completed detection results when there is a sudden power outage;

The instrument is equipped with a built-in thermal printer, which has automatic and manual printing selection functions;

7 Communication interface: USB serial interface and optional RS232 serial interface (can be connected to a barcode scanner to input the patient's medical record number).
