ABSTRACT:
A bandage useful, for instance, in medical applications includes a rupturable sheet or strip having encapsulated fluid (liquid or gas). The sheet or strip is disposed between the body portion to be bandaged and the outer surface of the bandage. The sheet or strip ruptues when a predetermined pressure is exceeded, thereby releasing the fluid for indicating that the bandage is applied too tightly. When the fluid is a liquid, such as a dye, the released liquid will stain the bandage. When the fluid is a gaseous substance, the release of the gas will be sensed. When a plurality of strips are used, one strip may contain a liquid and another one a gaseous substance, the strips rupturing at different predetermined pressures.
