Suction shell for tissue blood circulation

摘要

The suction shell is placed with its opening edge (9) on the skin of a patient for blood circulation through the skin and tissue. The shell is connected to a suction pump via a suction connection (4) for prodn. of a vacuum. Inside the suction shell is a counter pressure component against which the skin of the patient locates when there is an adequately large vacuum in the shell. The suction shell has a circular opening from which two opposite bearing grooves (14,15) in the inside of the shell extend vertical to the opening edge. A rotatable ball (11) acting as a counter pressure component with extending bearing pins (12,13) engages in the opening edge.
