Try to use function `get-buffer'.
Below is document of function `get-buffer':

,----
| (get-buffer BUFFER-OR-NAME)
| 
| Return the buffer named BUFFER-OR-NAME.
| BUFFER-OR-NAME must be either a string or a buffer.  If BUFFER-OR-NAME
| is a string and there is no buffer with that name, return nil.  If
| BUFFER-OR-NAME is a buffer, return it as given.
