Summary

This study tests a new device called VenAir that squeezes the legs to improve blood flow and prevent blood clots. About 105 healthy adults aged 20-64 will lie down while wearing different leg garments, and ultrasound will measure their blood flow. The goal is to see if VenAir works as well as a standard device already on the market.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
VenAir intermittent pneumatic compression device
What this could lead to
If it works, this could provide a new option for preventing dangerous blood clots in the legs and lungs.
What could go wrong
This is an early study in healthy people, not patients. It only measures blood flow, not actual clot prevention, so success here doesn't guarantee it prevents clots in real-world use.
