ABSTRACT:
A device for extracting pus, blood and other materials from beneath the skin. The device is made of a clear plastic tube open at both ends (10). One end is placed over the skin which has material to be extracted. The other end contains a plunger device (16) which creates a vacuum in the tube when it is withdrawn from the tube. As the vacuum pressure increases, the skin and underlying material are drawn into the tube until it is penetrated by a recessed piercing device (14) which is attached to an extrusion (12) approximately in the center of the tube (10). After being pierced, the underlying material is drawn from beneath the skin to the surface.
