Measurement device

Abstract

An insulin infusion device includes a cannula for infusing insulin under the skin and an insulin infusion section for storing therein insulin to be delivered to the cannula. The insulin infusion device also includes a motion measurement section that measures the tilt angle or rotation angle of a center axis of the insulin infusion section from a neutral position thereof, or vibration applied to the insulin infusion section, to output a measured value as motion information of living activity. The insulin infusion device also includes a controlling section that controls, based on the motion information, a process of notifying a user of the timing or recommended direction of priming of the insulin infusion section.

What is claimed is: 
     
         1 . An insulin infusion device comprising:
 a cannula for infusing insulin under the skin;   an insulin infusion section for storing therein insulin to be delivered to the cannula;   a motion measurement section that measures the tilt angle or rotation angle of a center axis of the insulin infusion section from a neutral position thereof, or vibration applied to the insulin infusion section, to output a measured value as motion information of living activity; and   a controlling section that controls, based on the motion information, a process of notifying a user of the timing or recommended direction of priming of the insulin infusion section.   
     
     
         2 . The insulin infusion device according to  claim 1 , further comprising a recording section that records therein the motion information. 
     
     
         3 . The insulin infusion device according to  claim 2 , further comprising a communication section that transmits the motion information recorded in the recording section. 
     
     
         4 . The insulin infusion device according to  claim 2 , further comprising a display section that displays thereon the motion information recorded in the recording section. 
     
     
         5 . The insulin infusion device according to  claim 1 , further comprising:
 a biosensor which selectively responds to a specific analyte in a biological fluid for detecting the presence or concentration of the analyte in the biological fluid;   an analyte measurement section that measures a characteristic amount of the analyte with the biosensor; and   a recording section that records therein the motion information and the characteristic amount with the motion information and the characteristic amount associated with each other.   
     
     
         6 . The insulin infusion device according to  claim 5 , wherein the biosensor is a continuous glucose monitoring sensor to be inserted under the skin. 
     
     
         7 . The insulin infusion device according to  claim 5 , wherein the biosensor is a blood glucose sensor for measuring blood glucose level. 
     
     
         8 . The insulin infusion device according to  claim 1 , further comprising a pump section for delivering insulin stored in the insulin infusion section to the cannula, 
 wherein the controlling section estimates, based the operation time of the pump section, the quantity of insulin being delivered by continuous subcutaneous insulin infusion or the quantity of the last bolus that is still active in the body (insulin on board), and records the estimated quantity in the recording section.   
     
     
         9 . The insulin infusion device according to  claim 1 , further comprising a living activity calculation section that calculates, based on the motion information, living activity level in terms of METs.
