Cuff for blood pressure monitor, blood pressure monitor, living body pressing apparatus, and living body information measuring apparatus

A blood pressure monitor, comprising:

• a cuff for a blood pressure monitor including a fluid bag inflated and deflated as a fluid comes in and out, and an elastic member wound annularly around an outer side of said fluid bag and changeable in size in a radial direction;
• an inflating/deflating portion for inflating and deflating said fluid bag;
• a pressure detecting portion for detecting a pressure in said fluid bag;
• and
• a blood pressure value calculating portion for calculating a blood pressure value based on pressure information detected by said pressure detecting portion;
• wherein
• said fluid bag has an inner wall portion located on an inner side when wound around a living body, an outer wall portion located on an outer side than said inner wall portion, and an engagement portion extending from a side end portion in a width direction of said fluid bag, and
• said engagement portion is folded at said side end portion toward said elastic member, and secured in an immovable manner to a position on the side of said elastic member with respect to an outer surface of said outer wall portion.

A living body pressing apparatus, comprising:

• a fluid bag including a working face pressing a surface of a living body;
• and
• a base portion arranged along a main surface of said fluid bag located opposite to said working face;
• wherein
• said fluid bag has an engagement portion extending from a side end portion of said fluid bag, and
• said engagement portion is folded at the side end portion of said fluid bag toward said base portion, and secured in an immovable manner to a position on the side of said base portion with respect to the main surface of said fluid bag located opposite to said working face.

A living body information measuring apparatus, comprising:

• a living body pressing apparatus including a fluid bag having a working face pressing a surface of a living body, and a base portion arranged along a main surface of said fluid bag located opposite to said working face;
• an inflating/deflating portion for inflating and deflating said fluid bag;
• a pressure detecting portion for detecting a pressure in said fluid bag;
• and
• a blood pressure value calculating portion for calculating a blood pressure value based on pressure information detected by said pressure detecting portion;
• wherein
• said fluid bag has an engagement portion extending from a side end portion of said fluid bag, and
• said engagement portion is folded at the side end portion of said fluid bag toward said base portion, and secured in an immovable manner to a position on the side of said base portion with respect to the main surface of said fluid bag located opposite to said working face.

A living body information measuring apparatus, comprising:

• a living body pressing apparatus including a fluid bag having a working face pressing a surface of a living body, and a base portion arranged along a main surface of said fluid bag located opposite to said working face;
• a pressure-sensitive portion provided on said working face of said fluid bag;
• an inflating/deflating portion for inflating and deflating said fluid bag;
• and
• a pulse wave measuring portion for measuring a pulse wave based on pressure information detected by said pressure-sensitive portion;
• wherein
• said fluid bag has an engagement portion extending from a side end portion of said fluid bag, and
• said engagement portion is folded at the side end portion of said fluid bag toward said base portion, and secured in an immovable manner to a position on the side of said base portion with respect to the main surface of said fluid bag located opposite to said working face.
