Blood state analysis device, blood state analysis system, blood state analysis method, and program

A blood state analysis system comprising:

• an electrical characteristic measurement device including
• an electrical characteristic measurement device that chronologically measures an electrical characteristic of blood of a patient, which is an analysis target, in a particular frequency or frequency band;
• and
• a blood state analysis device including
• a processing device and a memory device containing instructions that, when executed by the processing device, are configured to:
• extract a feature from chronological change data of the measured electrical characteristic of the blood of the patient, in two or more frequency bands,
• evaluate the blood of the patient on the basis of the extracted feature,
• classify the blood of the patient according to thrombosis risk on the basis of a result of the evaluation, wherein the blood is classified by use of a numerical value representing the at least one extracted feature and wherein the numerical value is a change amount δA (=A (fx,ty)/A (fx,ta)) of an electrical characteristic value A of the blood at a given frequency fx from a reference time to to a given time ty, and
• output an indication of thrombosis risk of the patient based on the classification of the blood of the patient and, upon indication of thrombosis risk, instruct administration of an anti-platelet aggregation agent or an anti-coagulant agent to the patient.

A non-transitory computer-readable medium containing instructions that, when executed by a processing device, cause the processing device to execute a blood state analysis method comprising:

• extracting a feature from chronological change data of an electrical characteristic of blood of a patient in two or more frequency bands;
• evaluating the blood of the patient on the basis of the extracted feature;
• classifying the blood of the patient according to thrombosis risk on the basis of a result of the evaluation, wherein the blood is classified by use of a numerical value representing the extracted feature and wherein the numerical value is a change amount δA (=A (fx,ty)/A (fx,ta)) of an electrical characteristic value A of the blood at a given frequency fx from a reference time ta to a given time ty;
• and
• outputting an indication of thrombosis risk of the patient based on the classification of the blood of the patient and, upon indication of thrombosis risk, instructing administration of an anti-platelet aggregation agent or an anti-coagulant agent to the patient.
