A woman has been charged with attempted murder after allegedly stabbing her partner while he was being treated at a mental hospital in Brisbane.

Police say the 28-year-old took a knife to the Toowong Private Hospital and repeatedly stabbed her partner, 38, in the neck and upper body on Sunday evening.

Staff made numerous triple 0 calls for help, and there are reports some of the workers restrained the woman until police arrived.
