Blood pressure device part importing Bulgaria

I am looking for the following with a Air Stem attached as you can see on the Picture

this is theek Air Ballon , just a little thinker than the normal with a Connector attached on the top
can you as well check if you can find a manufacturer for this device please

in place of the pressure cuff we will need a balloon to be installed . if you would like I can send you a picture

this product that we are asking its something we have invented
and we have used the same parts as of a Blood Pressure device
now we need to do a mass production
as well we have no need for any medical licences
its for Sportive people,
