Abstract

A pulse sensing patch and methods of forming and using the same are provided. The patch preferably includes a main body having an upper surface, a lower adhesive surface and an opening positioned in a medial portion of the main body. The pulse sensing patch also includes a housing having upper and lower portions positioned to surround the opening in the medial portion of the main body. The patch further includes a pulse sensor positioned within the housing for sensing a pulse, and a visual indicator positioned to overlie the pulse sensor within the housing for displaying a visually recognizable pattern of the pulse. The method of forming the medical pulse sensing patch includes forming an opening in the medial portion of the main body, positioning pulse sensor for sensing a pulse within the opening of the main body, and positioning a housing having upper and lower portions to surround the pulse sensor. The method of using the pulse sensing patch preferably includes removing the pulse sensing patch from a sterile package, positioning the pulse sensing patch to overlie a user'"'"'s skin, activating the pulse sensing patch by removing a lubricant cover positioned adjacent a lower surface of the medical pulse sensing patch, and visualizing a predetermined indication pattern representing the pulse.
