Cuff for Blood Pressure Monitor and Blood Pressure Monitor Having the Same
First Claim
1. A cuff for a blood pressure monitor, comprising:
- a fluid bag inflated and deflated as a fluid comes in and out;
an elastic member located on an outer side of said fluid bag when said fluid bag is wound around a living body, and wound annularly and elastically deformable in a radial direction; and
a bag-shaped cover body containing said fluid bag and said elastic member therein and applied to the living body such that a width direction thereof is substantially parallel to an axial direction of the living body, whereinsaid bag-shaped cover body includes an inner wall portion located on a living body side when the bag-shaped cover body is wound around the living body, and an outer wall portion located on a side opposite to the living body side when the bag-shaped cover body is wound around the living body,said elastic member includes a large curvature region and a small curvature region in a winding direction thereof to cause the cuff for a blood pressure monitor to fit the living body, andin a state where said fluid bag is deflated, said inner wall portion at a portion corresponding to the large curvature region of said elastic member is stretched in said width direction.

Abstract
A cuff for a blood pressure monitor includes a bag-shaped cover body containing an air bag and a curled elastic member as a curved elastic plate. The bag-shaped cover body is formed by stacking an inner cover member located on a living body side when applied and an outer cover member located on a side opposite to the living body side when applied, one on the other, and sewing their rims. The curled elastic member contained in the bag-shaped cover body includes a large curvature region and a small curvature region in a winding direction thereof to fit a measurement site. In a state where the air bag is not inflated, the inner cover member at a portion corresponding to the large curvature region of the curled elastic member is stretched in a width direction thereof. With this configuration, a cuff for a blood pressure monitor which is less likely to have wrinkles in a bag-shaped cover body can be provided.
