The charity set up by David Rathband says it plans to broaden the support it offers to members of the emergency services.
The Blue Lamp Foundation was established to help personnel who are injured in the line of duty.
So far, it has concentrated on helping people with physical injuries.
The Foundation's chairman says it now wants to offer practical support to people coping with emotional trauma and mental health issues.
Peter Sweeney said:
"We can't forget the pain and suffering that David suffered personally.
The last thing we want is another member of the emergency services, injured in the line of duty, committing suicide because of the severity of their injuries."
