AIRBAG FOR BLOOD PRESSURE MEASURING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

An airbag for a blood pressure measuring device for fixing a cuff, including: a main sheet member which spreads in two layers forming a bag body, wherein a constricted portion is formed on the bag body, the constricted portion narrowing the air chamber with respect to the width direction, a pair of sub sheet members are disposed so as to correspond to the respective layers of the main sheet member, the sub sheet member occupying a region including at least a portion corresponding to the constricted portion, and the pair are respectively welded to the layers of the main sheet member at the constricted portion, the pair being welded to the corresponding layers of the main sheet member at a center near portion away from the constricted portion toward a center side with respect to the width direction.

1. An airbag for a blood pressure measuring device for fixing a blood pressure measuring cuff to an upper arm portion of a person to be measured, the airbag comprising:
a main sheet member which spreads in two layers in a longitudinal direction and in a width direction perpendicular to the longitudinal direction so as to form a bag body which defines an air chamber therein, wherein at least one constricted portion is formed locally on the bag body with respect to the longitudinal direction of the bag body, the constricted portion being formed by welding the two layers of the main sheet member so as to narrow a size of the air chamber with respect to the width direction, a pair of sub sheet members are disposed so as to correspond to an inside or an outside of the respective layers of the main sheet member, the sub sheet member occupying a wider region than the constricted portion including at least a portion corresponding to the constricted portion, and the pair of sub sheet members are respectively welded to the corresponding layers of the main sheet member at a portion corresponding to the constricted portion, the pair of sub sheet members being welded to the corresponding layers of the main sheet member at a center near portion away from the constricted portion toward a center side with respect to the width direction.
