How can you use a healing surge during battle?

In the PHB it says:

Even in a heated battle, you can heal. You can heal yourself by using your second wind (see page 291), an ally can use the Heal skill (see page 185) on you, and an ally can use a healing power on you.

But I want to know if there is a way to just use a healing surge as a standard action.(by the book)
Can you just use a healing surge without it being triggered by any of the above stated actions?

Thanks in advance!
