ABSTRACT:
Blood is stored under refrigeration at a temperature of about 4.degree. C. When it is utilized on a relatively rapid basis within a surgical theater it is transported by tubing through a blood warming apparatus which, while warming the blood, causes an outgasing of entrained air. This air is trapped in an air trap receptacle having a drip chamber within which a gas-blood interface is developed. To assure that the capacity of the trap is not exceeded, an improved technique of gas removal and interface level setting is provided wherein access is achieved essentially through the entrance region of the gas trap receptacle.
