The present invention provides a medical safety device for holding a container. The medical safety device is used to hold the container while extracting liquid by a syringe from the container. The medical safety device is a unitary flexible main body having two opposing ends. On each end is a hand hold for grasping by the user's hands. A longitudinal slit is positioned within a center portion of the main body. When opposing force is applied to both ends toward the center of the main body, the slit widens, allowing positioning of the container within the slit. Release of the force upon the ends narrows the slit and the container is retained within the slit of the medical safety device. The user may then extract the liquid from the container without holding the container.
