Title:
BODY FLUID ANALYZER
Document Type and Number:
Japanese Patent JP3604804
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automatically and continuously perform a series of processes required for measurement by pressurizing a pressure band (cuff) for making body fluid come out from a punctured finger, optically detecting information relating to the body fluid which comes out from the finger, displaying a measured value decided by the result and performing control by a computer.
SOLUTION: After a puncturing blade is projected, a pump is driven (S1-S2) and the cuff is pressurized. The cuff pressurizes the finger and squeezes out the body fluid from the damaged skin. When an apparent blood pressure reaches a prescribed value P by the pressure of the cuff, judgement is turned to YES (S3). When the drive of the pump is stopped corresponding to the judgement (S4), air inside the cuff is promptly exhausted (S5). When the squeezed body fluid reaches a detection part, a light emitting element emits light and the light is reflected in the detection part and received in a light receiving element (S6-S7). Output from the light receiving element is sent to the computer, an arithmetic operation started, and when the arithmetic operation is ended after the lapse of the time (t), the measured value is displayed at a display part (S8-S11).
