Abstract
Methods and apparatus for handling a compatible solution relative to a circulatory system of a living organism employ a recipient device having a circular cavity tending to retain gas bubbles. A pocket communicating with an opening for injecting the compatible solution is provided in the circular cavity. A unidirectional jet of the injected solution is formed by blocking flow of the injected solution at a closed end of the pocket, thereby forming a pressure head in the pocket. The injected solution is then ejected through an outlet of the pocket and is swept in a swirling motion along a boundary of the cavity, thereby wiping gas bubbles from such boundary, for bleeding to atmosphere.
