Abstract
A compression therapy apparatus and a method for manufacturing and applying compression with the same may include a bandage and a tension indicator coupled to the bandage. A tension indicator may include a film having layers of liquid crystal droplets deposited on a polymer matrix. The tension indicator can be adapted to color shift under tension between the first end and the second end of the bandage.

A compression therapy apparatus, comprising:
- a bandage;
- and
- a tension indicator comprising layers of liquid crystal droplets deposited on a polymer matrix, the tension indicator coupled to the bandage and adapted to color shift under tension.
A method of manufacturing a bandage comprising:
- providing a bandage;
- and
- coupling a tension indicator to the bandage, the tension indicator adapted to color shift under tension, the tension indicator comprising layers of liquid crystal droplets deposited on a polymer matrix.
A method for providing compression therapy to a tissue site, the method comprising:
- providing a compression therapy apparatus, comprising:
- a bandage, and
- a tension indicator comprising layers of liquid crystal droplets deposited on a polymer matrix, the tension indicator coupled to the bandage and adapted to color shift under tension;
- securing the first end of the bandage to the tissue site;
- applying tension to the bandage;
- monitoring the tension indicator for the color shift;
- and
- if the tension indicator color shifts, wrapping the bandage around the tissue site.
