Abstract
A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide. The color change may be visible from both sides of the detector. In some examples, the respiratory detector may be a biocompatible and conformable sticker for mounting on a person's face or an oxygen delivery device.
Claims20
A universal respiratory detector for detecting a respiratory gas and displaying a respiratory status based on the gas, the respiratory detector comprising:
- a first side and a second side opposite the first side;
- a cover layer, wherein the cover layer covers at least part of a backing;
- a respiratory sensor layer comprising the backing and a visual indicator on the backing, the visual indicator configured to reversibly change color when a respiratory gas parameter changes and to display the color change, wherein the color change is visible from both the first side and the second side;
- and
- a biocompatible adhesive on the cover layer and a release liner on top of the biocompatible adhesive,
- wherein the universal respiratory detector is a sticker, and further wherein the detector is configured to conform to a curved or variable surface contour of an oxygen delivery device or a face of a user and configured to flex and move together with movement of the oxygen delivery device or the face of the user.
