There are already non-venting systems that use a reasonable amount of helium (7L) to manufacture and don't require refilling. It just was not a design consideration previously. https://www.philips.com.au/healthcare/resources/landing/the-...

While 7 liters is less than 1,500, why would they call this a helium-free system?

They say helium free operation, as they say you never need to deal with the helium (e.g. no refilling)
