My health care facility is looking for a new kind of bracelet to put on our confused (or combative) residents to let us know if they try to get outside. We need something strong that cannot be removed by the patient, only staff with appropriate tools. Currently we use a 1/2 inch copper bracelet where we drill a hole in the device that activates the alarm (a square plastic thing) and attach the copper chain to it and put in on the resident's wrist or ankle. Our current supplier is no longer making these chains and the boss is looking for something new. Another downside to the copper is it discolors itself and the patient's skin. Anyone have any ideas? Do you happen to know what they use on inmates to keep them from taking ID bracelets off? Thank you!
