Suction pump with optical status indicator

Abstract

The invention relates in one variant to a suction pump (1) for sucking body fluid, comprising an optical status indicator (5) for displaying a light signal as a function of the operating state of the suction pump (1), the optical status indicator (5) is arranged on at least two points of the outer surface of the suction pump (1), the surface normals of which are at an angle of at least 5° to one another. In a second variant, the invention relates to a suction pump (1) for sucking body fluid, including an optical status indicator (5) for displaying a light signal as a function of the operating state of the suction pump (1), wherein the suction pump (1) has on its underside at least one stand (13) for support on a support surface, the status indicator (5) is arranged on the underside of the suction pump (1) so that the light signal is emitted in the direction of the support surface. In a third variant, the invention relates to a suction pump (1) for sucking body fluid, including an optical status indicator (5) for displaying a light signal as a function of the operating state of the suction pump (1), the status indicator (5) occupying at least 5% of the surface of the suction pump (1).
