Sterile Water Generator
Currently, deployed medics are required to transport, maintain and be resupplied with liquid-based medications and materials that are heavy, expensive to transport, perishable and may require refrigeration. Many medications and materials are now or will be available in the future as dehydrated formularies that require Sterile Water for Injection (SWFI) to rehydrate them for immediate use, such as freeze-dried platelets. It would be far better to be able to sterilize locally available potable water, but no hand-held, portable technology exists that will allow medics on the battlefield to generate SWFI.
Unit Specifications:
Can deliver 1 liter of SWFI water in ten minutes and 1 liter in six minutes.
Weighs less than 4 pounds.
It is reusable for 5 - 10 cycles before requiring disposal, depending on water quality.
System size between 0.15 cubic foot and 0.08 cubic feet.
Maintains the sterility of the water during transfer to the IV bag.
Waterproof and durable in rough conditions.
Can run continuously without overheating.
Uses DC/DC converter to maintain constant 12V to motor to avoid performance loss as battery drains.
Cleaned by backwashing - cleaning instructions provided.
In collaboration with Mountain Safety Research (MSR), a division of Cascade Designs, TDA Research Inc has developed a portable, hand-held sterile water generator. This device can make sterile water from any potable water source. It generates small amounts of sterile water to reconstitute dried plasma, dehydrated medications and other freeze dried medicine at or near the point of injury. Our device combines a hollow fiber filter developed by MSR for the US Marine Corps to remove microbiologicals, a carbon column to remove organic carbon species, and a Purolite ion exchange resin to remove soluble ions.
