Holder for medical use fixed by vacuum
First Claim
1. A holder for diagnostic or therapeutic devices, for attachment to the skin by the action of vacuum provided through a hose from a vacuum source, and which comprises a diagnostic or therapeutic arrangement (1), which is adapted to be connected to a measuring instrument or an electrical power source (via 7) or both, and which holder is adapted to be attached with a front side (4) engaging a skin surface, and which comprises a rigid backpiece (3), to which is attached the diagnostic or therapeutic arrangement (1) and a sealing means (2), which surrounds said arrangement (1) and comprises a sealing ring (9), circumferentially arranged around said arrangement (1) and ending in a sealing lip (13), which sealing ring (9) in a working state is adapted to abut against said skin surface such that a volume connected to the vacuum source is delimited by said skin surface and the sealing means, characterized in that said arrangement (1) and the sealing lip (13) are movably arranged with respect to each other under action of a resilient force (via 17), which urges said arrangement (1) and a plane defined by said sealing lip (13) away from each other, from a working state (FIG. 3) to an idle state (FIG. 2), which movement activates valve means for closing the supply vacuum to said volume under vacuum, in that said arrangement (1), in both a working state and an idle state, remains stationary relative to the backpiece (3), and in that the sealing lip (13) is situated on a movable ring (9), which is supported against the backpiece (3) in said working state.

Abstract
The invention relates to a holder for diagnostic and therapeutic devices fixed by vacuum. Vacuum is supplied by a hose or tube (8), in which one or several electrical conductors (7) for electrical power supply or signal transmission are drawn. The holder comprises a rigid backpiece (3), an intermediate elastomeric element (2), and the diagnostic or therapeutic device (1). The intermediate element (2) comprises a comparatively stiff sealing ring (9), which in a working state is supported against the skin by a sealing lip (13) and with its opposite side against the backpiece (3). The device (1) is rigidly connected to the backpiece (3), but the sealing ring of the intermediate element (2) is movable and, outwardly from the backpiece, slightly resilient (via resilient means 17). When the lip-side of the ring is not loaded and the ring thus pressed outwardly, a vacuum valve is closed automatically through the action of the intermediate component, and is re-opened when the holder is pressed against the surface of the skin, whereupon the holder is held firmly by suction.
