ABSTRACT:
The invention proposes a liquid heating bag1, in particular, a blood heating bag and a bag heating means30for heating liquids, e.g. cooled blood, which flow through the liquid heating bag1, to a temperature suitable for transfusion. The liquid heating bag1has a flow volume3formed by at least two flexible plastic foils which are connected to each other at four delimiting edges5, 6, 7, 8, wherein the flow volume3has a flat, substantially trapezoidal basic shape which is delimited by the delimiting edges5, 6, 7, 8. An inlet line opening12and an outlet line opening14are disposed on a first delimiting edge5, and an insertion tab15is disposed on a second delimiting edge6opposite to the first delimiting edge5. The liquid heating bag1has a liquid flow guiding seam20which is formed by connecting the plastic foils in the region of the flow volume3. The insertion tab15is formed as part of the plastic foils, which projects past the second delimiting edge6.
