Researchers in Australia have invented a new device to warm blood without the need for a power source in emergency in-the-field transfusions, reports the Adelaide Advertiser.
Medics simply need to pull a cord and the blood heats up through a chemical reaction.
Researchers from Flinders Biomedical Enterprises designed the portable and disposable device Intraheat. As blood is stored between two and six degrees it must be warmed up before being put into a patient or they can get dangerously cold.
The company has received a grant and is now in the process of developing the product to go on the market.
