Hiya, i have this self-inflated mattress that have a hard time inflating itself. So i still want to blow it up with a pump of some sort. The problem is, the mattress has this butterfly valve that cannot be taken off.

So im thinking to create an adapter from the valve to an opening that can actually be blown by a pump?

Looking at the photos (there are 2 of them) do you have any ideas? it has this bumps that makes it a bit difficult. Im thinking to use a hose and probably shoot it with a heat gun so it will follow the shape the valve. But im open to other suggestions.

Thanks in advance.
