hand drawn diagrams stored in a medical record app?

[Heitzso]

I saw the current domestic violence forms that would need to be entered 
into some form of a database and there are two simple pictures on the 
form of a man and a woman.  On these pictures the reporter is supposed 
to hand draw in the various injuries.

?? Is there any software (open source or otherwise) that can be easily 
setup to handle this?

Thanks,
