Any ideas on how to provide vacuum to an aspirator? Looking into some sort of small pump, that could be thrown together from like Lowes, or a home improvement store. The lead acid battery in my portable suction unit, leaked out, maybe from leaving it plugged in. I tossed it, so I got an idea of just making a Rico RS Hand Pump Aspirator into a powered unit. It would be for actual EMS use. Haven't been able to find any usable replacements on ebay, just looking for ideas from the idea experts, hence why it's in the off topic category.
