Design Of Auto Hematology Analyzer Of 5-part Based On PC

With the rapid development of fundamental medicine and extensive application of advance science and technology and laboratorial instrument, laboratory medicine become more and more importance in the clinical making diagnosis and giving treatment. In China, thanks to the deepening of reform and open door to the outside world, meanwhile intercommunicating technology and information with foreign countries and the development of computer technique improved course of research of laboratory medicine. The development of hematology analyzer is promoted as well.In this paper a design of auto hematology analyzer of 5-part based on PC is presented, which realized testing of white blood cell, red blood cell, platelet and hemoglobin. The analyzer can carry out essential parameters of testing such as WBC, RBC, PLT, HCT, MCV, MCH, MCHC, RDW, MPV, PCT and PDW etc. and draw histogram of testing of white blood cell, red blood cell and platelet simultaneously. Its software possesses querying results of testing that can be reported to print.Firstly principle of blood cell testing with related technique application, such as Coulter and Light Scatter, is presented in the paper. And then the paper introduce in detail about hardware be selected and PCI broad for controlling and they characteristic and function. Summarizing hematology testing full process is the next. In addition, the paper introduced the capability of software, VB 6.0 version and Matlab's ActiveX protocol and database toolbox, that is used by hematology testing program.
