A blue dye housed in a blister is held adjacent to a micro-porous membrane. Upon squeezing the activation button the dye comes out of the blister and into contact with the membrane. The temperature of the chilled blood bag solidifies the liquid, and thus unable to move through the membrane. If the temperature rises to or above the threshold temperature of 10°C/50°F, the dye changes to liquid form, moves through the membrane and indicates a breach when blue dye shows up in the indication window.
If stored under the correct conditions, this is highly unlikely to happen, but if it does, the built-in activation window lets you know it. If this happens, don’t use the indicator and select another. There is no need to contact us, as we ship 1 or 2 extra indicators per pack free of charge anyway.
adminWhat if one of the indicators in the box is showing the indication window already blue before I’ve squeezed it?
Blood Temp 10+ indicators allow you to monitor the temperature of blood in a blood bag when it leaves the blood bank to go to a ward, operating room or other location.
Blood Temp 10+ indicators require no power and can be read easily and instantly by the end user. Indication is irreversible and each indicator has a unique serial number to ensure traceability.
adminWhy use Blood Temp 10+ when all our blood bags are kept in temperature controlled fridges?
