Can't say I've heard of or seen those but on Jorge Sprave's slingshot channel on YouTube he designed battery drill operated ventilator using it to depress and release what would be a manual ventilator. That was back when there was a shortage of ventilators and they were believed to be the answer as treatment for covid19.
Good to hear some companies are trying the same automation idea on high pressure air pumps that'll make life easier for those who for some reason don't just use an air cylinder.
