Medical Alarm Pendant I'm In The U.K. And Need A Medical Alarm 24hr Hour Panic Button For My Mother...?

I'm in the U.K. and need a medical alarm 24hr hour panic button for my mother...? - medical alarm pendant

This is the alarm that comes as a pendant or pin and it is a medical emergency that can be pressed and passed through a line of 24 hours care .... I can not find, you need a UK real. The indication to do so, but we have been trying for months and still nothing has happened. So grateful if someone can help out there!
