DEVICE FOR MEASURING BLOOD PRESSURE INFORMATION

摘要

A blood pressure meter is provided with a cuff (20A) having therein an air bag and also with an expanding and contracting mechanism for expanding and contracting the air bag.  The cuff (20A) has a tubular cuff body section (30), and the cuff body section (30) is provided with fastening belts (31, 32) wrapped around the outside of the air bag and also with a fastening length adjusting mechanism (50) for variably adjusting the fastening length of the fastening belts (31, 32) relative to an upper arm.  The blood pressure meter is also provided with an upper arm circumference measuring section for measuring the circumferential length of the upper arm by using the fastening belts (31, 32).  The fastening belts (31, 32) have a barcode (74) for specifying the circumferential length of the upper arm.  The circumference measuring section includes a photoelectric sensor for specifying the circumferential length of the upper arm by reading the marker (74).  Thus, the blood pressure meter has a function capable of accurately and precisely measuring the circumferential length of the upper arm which is a portion to be measured.
