Portable Blood Detection System on the Basis of Dry-Type Chemical Method

Abstract:

This paper presents a portable blood detection system on the basis of dry-type chemical method. Controlled by TM320VC5509A, a high-precision Digital Signal Processor, provided light source by line spot semiconductor laser (LD), converted between light and electricity by photocoupler, the system can fulfill the conventional detection and measurement of blood cells parameters. As for the stability of the system, the test results showed that the relative standard deviation of the parameters of the blood cells were all below 1.7%. The contrast experiment on Sysmex XT-1800i showed that with hematocrit (HCT), hemoglobin (HGB), lymphocytes and moncytes (LM), granulocytes (GRAN), platelets (PLT) and white blood cell (WBC) as contrast items, the correlation coefficients of the system were 0.9910.9720.9520.9860.979 and 0.985 respectively. The volume and time measurements of the system were designed as (25×20×10) cm³ and 60s. The system can fulfill some functions such as indicating records, seeking information and deleting. The system will have a wide application prospect in rapid test of blood in field and emergency examination.
