  • Gas diffusion liquid storage bag and method of use for storing blood
    Patent number: 4132594
    Abstract: It has been found that the shelf life of stored whole blood may be doubled by adding a buffer which maintains a desired pH level. However, this buffer causes the generation of CO.sub.2 which, if not removed at a controlled rate, causes the pH value of the blood to decrease, which shortens the useful life of the blood. This invention provides a blood storage bag which permits the CO.sub.2 to be diffused out at a controlled rate into the atmosphere, thereby maintaining the desired pH value while providing a bag strong enough to permit handling thereof.
