Medical Term Help

I had a patient that had an esophageal perforation. As a result, she had this bag attached to her (just below her left clavicle) that collected saliva. The patient's file referred to this bag as a 'neck spit bag', but I was wondering if anyone knew the formal name or proper medical term for the bag. I was interested in learning more about it, but it's difficult to find information without the formal name.

thanks
First time I've ever seen a clear, concise name for anything in the medical field. I can see why it grabbed your attention.

I looked online for it too. I found a lot of information about it but the bag was just referred to as a 'collecting bag' or a 'drainage bag'. Just in case you want to know, I just went to google and typed in 'esophageal perforation clavicle saliva bag'.There was little info about the bag and the documents were mostly about the procedure done.
