Experimental research on optical card system in the field of blood transfusion.

我们采用光卡系统保存献血者的记录，以确保他们的健康。作为试点项目，选取10名埼玉血液中心工作人员，在征得知情同意后，将其个人信息、献血情况、血液生化实验室数据记录在该卡片系统中。奥林巴斯公司的光卡读卡器通过SCSI电缆与NEC公司的PC9801RX连接。当将光卡插入读卡器时，监视器屏幕上就会显示个人信息，包括姓名、性别、出生日期、献血ID、地址、电话号码、血型等。我们可以选择两种显示个人健康信息的类型。一种是根据每次捐献时的体重、血压、肝功能、营养、红细胞计数等状况，用三级符号显示；订单是以表的形式显示实际数据。这些实际数据可以在捐赠的时间过程中（4个月，1年，3年）同时转换成包含三项的图形。最后输入当天的捐献资料：捐献类型、体积、身高、体重、血压、血液比重、心电图等。所有这些展示只需要几分钟。这张卡片系统将向献血者承诺保持和促进身体健康。

We adopted an optical card system to maintain the records of blood component donors to ensure their good health. As a pilot project, 10 working staffs in the Saitama blood center were selected, and their personal informations, donations, and hemato-biochemical laboratory data were documented in this card system after obtaining the informed consent. The optical card reader-writer from Olympus Co.were connected with PC9801RX from NEC Co.by a SCSI cable. When an optical card is inserted into the reader-writer, a display of individual information including name, sex, birth day, blood donation ID, adress, telephone number, blood type, etc.appears in the monitor screen. The we can select two types of displays of individual health information. One is displayd by three ranks of symbols according to the status of body weight, blood pressure, liver function test, nutrition, and red cell count, etc.at each donation ; the order is a display of the actual data in the form of tables. These actual data can be converted to graphics containing three items simultanously in the time course of donations (4 monthes, 1 year, 3 years). Finally we input the document of donation on that day : type of donation, volume, height, body weight, BP, blood specific gravity, ECG, etc.It only takes a few minutes for all these presentations. This card system will promise the blood component donors for keeping and promoting good health.
