Claim Text:
1. A blood analysis apparatus comprising: a sampling unit configured to sample a blood sample by obtaining a specimen from the blood sample; a preparation unit configured to dilute and prepare the specimen to produce as a measurement sample a first measurement sample for measuring a ratio of a content of glycohemoglobin to a content of hemoglobin in the specimen and a second measurement sample for measuring a concentration of glucose of the specimen; a glycohemoglobin measuring unit configured to measure the ratio of a content of glycohemoglobin to a content of hemoglobin in the specimen from the first measurement sample; and a glucose measuring unit configured to measure the concentration of glucose of the specimen from the second measurement sample, wherein the glucose measuring unit comprises an enzyme electrode for the measurement of the concentration of glucose, the preparation unit comprises a dilution bath, the blood analysis apparatus further comprises a sample injection valve for introducing the first measurement sample prepared in the dilution bath of the preparation unit to the glycohemoglobin measuring unit, a pipe for connecting the sample injection valve and the dilution bath, and a sample introducing pump for introducing the first measurement sample from the dilution bath to the sample injection valve, the enzyme electrode is provided at the dilution bath, and the dilution bath is connected to a drain system via an open/close valve that is provided at an upper part of the dilution bath, wherein the open/close valve, when in an opened state, causes excessively supplied cleaning fluid to be discarded to the drain system when the cleaning fluid is supplied to the dilution bath.
