Back when I was a kid, there was a famous (infamous) commercial in which a grandmotherly type fell, hit a button on her life saving device and was able to call for help.
Ah, but what if that elderly person fell and was hurt so badly she couldn't even reach the button on her life saving device? What if she was so injured she couldn't even press that button?
Fortunately, there are other devices available in the Medical Alarm field that can help the elderly who can't call for help themselves. One of them is the FALL ALERT detector that will automatically alert medical personnel when a person has fallen and can't push a button.
Another is the GPS Tracking Bracelet that is worn on the wrist and features a two-way speakerphone that allows the wearer to call for help. It also has a GPS tracking system that can help authorities track down someone who has gone wandering and can't be located -- very handy for people with ailments such as Alzheimers who have become forgetful.
Those old "push button" devices were handy items that saved more than a few people. Technology, however, has replaced those devices with products that are even more beneficial to the people who rely on them.
