Abstract

A blood sugar analyzer has a reaction cell which houses a fixed enzyme membrane and measuring electrode and which receives a blood specimen, to cause a chemical reaction between the specimen and membrane for measuring the blood sugar concentration in the specimen on the basis of the reaction current generated in the electrode by the reaction. The analyzer also monitors the temperature in the cell and the sensitivity of the electrode, and a printer prints out data on the temperature and sensitivity. A digital control device controls overall operation of the analyzer.

Claims

1. A blood sugar analyzer having a reaction cell which houses a fixed enzyme membrane and a measuring electrode and which receives a blood specimen, to cause a chemical reaction between the blood specimen and the fixed enzyme membrane, for measuring the blood sugar concentration in the blood specimen on the basis of a reaction current generated in the measuring electrode by the chemical reaction, and including means for monitoring the temperature in the reaction cell, means for displaying informational data on the temperature to an operator in response to said monitoring means, and manually actuable input means for providing a test display signal, and wherein said display means displays a predetermined character pattern in response to said test display signal.

2. The blood sugar analyzer according to claim 1, wherein the means for displaying comprises a printer, and including a digital control device for executing automatic control operation of the analyzer in response to a predetermined sequence program and for enabling the printer to print measurement results in response to a printer controlling program, said digital control device being transferred from a sequence program operational mode to a printer controlling program operational mode in response to interrupt signals supplied at periodic time intervals as restart signals from the printer.

3. The blood sugar analyzer according to claim 1, wherein the monitoring means includes means for monitoring the sensitivity of the measuring electrode, and wherein the display means includes means for displaying informational data on the sensitivity to an operator in response to said monitoring means.

4. the blood sugar analyzer according to claim 1, wherein the display means comprises a printer.
