  • Exsanguinating device for displacing blood from a limb by compression
    Patent number: 4228792
    Abstract: An exsanguinating device for displacing blood from a limb by compression comprises a fluid-filled envelope in the form of a double-walled tube of elastomer with the inner and outer walls of the same unstressed dimensions. The device can roll onto the limb with the inner and outer walls exchanging positions. The inner surface of the envelope is preferably lubricated to prevent sticking where the inner wall folds at the ends. When a liquid fill is used this can serve as the lubricant.
