Our Mission

Help save lives across the entire continuum of emergency care

Our Vision

In an environment where every second counts, our vision is to completely eliminate the challenge of warming blood and IV fluids from the entire continuum of emergency care (i.e. from the most challenging points of injury, through the various transport platforms, and eventually within the most demanding hospital settings) in order to allow emergency care professionals to focus on what they do best – saving lives.

Advanced Technology That Transforms Emergency Care

Since 2009 QinFlow (short for Quality in Flow) has worked to develop and perfect a proprietary fluid warming technology (patented) that delivers unparalleled levels of warming efficiency. The company’s flagship line of products – the Warrior – provides front end rescue teams, first response teams, critical care transport teams, and emergency care professionals within various hospital settings with a high performance, reliable, simple to operate, and completely portable blood and IV fluid warming device that operates flawlessly in all environmental conditions in order to fight hypothermia and save lives. The Thermal Rescue product is applying the same technology in the animal care realm.

We are having amazing success and save cases this past year [2020]. Just last week we infused a unit of WARMED LTOWB in 2 min [250ml/min]. The patient received 3 on-the-ground and 2 in flight and survived a non-survivable GSW [gunshot wound] to the chest!
