Abstract: A personal identification system for collating an article requiring personal identification with a person using the article has a personal identification data reader for reading the image of a characteristic portion of a human body capable of identifying a person such as his fingerprint and digitizing the image data. Moreover, the system has a label printer for printing the personal identification data on a label as two-dimensional data codes and the personal identification data printed on the label is read by a label data reader serving as a two-dimensional data code reader. The personal identification data read by the personal identification data reader and acceptance or rejection of the collation result is decided. These operation histories are recorded and preserved in a hard disk.

Abstract: A cell surface antigen determination method for determining an immunocyte having an immune antigen-antibody complex composed of an antigen and an antibody combined therewith in a liquid which contains immunocytes having various antigens and also containing many kinds of antibodies, and an apparatus used in this method. In accordance with the inventive method and apparatus, non-specific reactions are restrained so as to reduce the background without using a complement.

Abstract: This invention is a switch bag type blood-gathering set used for transfusing blood gathered from a blood donor to the same blood donor again, and for newly gathering predetermined amount of blood from the blood donor. This switch bag type blood-gathering set comprises a liquid transferring member for introducing a physiological saline solution into the blood-gathering set, a blood transfusing member for introducing blood from a blood bag into the blood-gathering set, a blood-transfusing and gathering member for supplying blood to or gathering blood from the donor, a washing solution storing member for containing a waste liquor after priming in the blood-gathering set, and a blood storing member for storing blood gathered from the donor, and these constituents are connected by connecting tubes so as to not contact with the air outside.
