TTP Ventus introduces pressure-driven flow system for point-of-care diagnostics

New spin-out from TTP plc has developed 2nd generation Disc Pump tech., with applications in medical devices, healthcare, and scientific research.

TTP Ventus Ltd, a spin-out from TTP plc, created to bring disruptive new products to market, has announced the preview of its proprietary pressure-driven flow system for point of care diagnostics. The new system is built around the second generation of TTP Ventus’ award-winning micropump technology, Disc Pump, and offers precise flow control in a compact form factor, ideally suited for microfluidics products spanning point-of-care diagnostics to Droplet Digital PCR. TTP Ventus will showcase a demonstration of its pressure-driven flow system at the 69th AACC Annual Scientific Meeting & Clinical Lab Expo, at the San Diego Conference Centre, 30th July-3rd August, 2017, at booth #1658.

The TTP Ventus innovation allows the replacement of large, benchtop equipment, such as the pumps, regulators and valves required by existing pressure-driven flow systems, which often weigh several kilograms, with a palm-sized, self-contained module that contains the micropump and electronics, together weighing less than 50g. The TTP Ventus system brings advantages over other miniature pump systems targeting microfluidics, including ultra-smooth liquid flow, rapid response time and a wide dynamic range.

Tom Harrison, Business Development Manager, TTP Ventus, commented: “We developed Disc Pump to meet the demanding requirements of wearable medical technology, where our combination of size, high performance and silent operation is enabling a range of breakthrough medical devices. Whilst Disc Pump is a gas pump, we recognised that in applying our technology to pressure-driven flow of liquids, its unique set of attributes can bring substantial benefits. Owing to its unique operating mechanism, our pump can be controlled with unmatched precision, yet at the same time respond to full-scale set point changes in a matter of a few milliseconds. The compact form factor means it can be tightly integrated into products, reducing dead volume. All of this contributes to unrivalled real-time control performance in microfluidic applications.”
