Biological fluid analyzing device

Abstract

The biological fluid analyzing device for analyzing biological fluid by measuring optical characteristics of a sample has a sample receiving port 1 and a pump connection port 5. Between the sample receiving port 1 and the pump connection port 5, the analyzing device has either a combination of at least one sample-treating chamber 2a, 2b, 2c and at least one optical-measuring chamber 3a, 3b, or a combination of at least one sample-treating chamber, at least one optical-measuring chamber and at least one waste liquid reservoir 4. The sample receiving port 1 is connected with one sample-treating chamber; the pump connection port 5 is connected with a pathway 6 or waste liquid reservoir 4; and the sample-treating chamber and optical-measuring chamber are interconnected with the pathway, or the sample-treating chamber, optical-measuring chamber and waste liquid reservoir are interconnected with the pathway. This construction allows a series of reaction steps to be performed without being affected by physical properties of a liquid sample and thereby assures high level of precision in analyzing the liquid sample. This construction also enables measurements to be made easily.
