Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
270 words
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 can be connected to a measuring instrument or an electrical power source (via 7) or both, and which holder can be attached with its front side (4) to 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 abuts against said surface in that in the working state a volume connected to the vacuum source is delimited by said surface and the sealing means, whereby 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 strives to remove arrangement (1) and a plane defined by said sealing lip (13) from each other, from a working position (Fig. 3) to an idle position (Fig. 2), which movement is arranged to activate valve means for closing the supply of vacuum to said volume under vacuum, characterized by that said arrangement - (1), in both a working state and an idle state, adopts the same position relative to the backpiece (3), and that the sealing lip (13) is seated on a movable ring (9), which is supported against the backpiece (3) in said working position.
Claim 2
Dependent Claim
270 words
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 can be connected to a measuring instrument or an electrical power source (via 7) or both, and which holder can be attached with its front side (4) to 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 abuts against said surface in that in the working state a volume connected to the vacuum source is delimited by said surface and the sealing means, whereby 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 strives to remove arrangement (1) and a plane defined by said sealing lip (13) from each other, from a working position (Fig. 3) to an idle position (Fig. 2), which movement is arranged to activate valve means for closing the supply of vacuum to said volume under vacuum, characterized by that said arrangement - (1), in both a working state and an idle state, adopts the same position relative to the backpiece (3), and that the sealing lip (13) is seated on a movable ring (9), which is supported against the backpiece (3) in said working position.
Claim 3
Dependent Claim
30 words
A holder according to claim 1, characterized by that both the diagnostic or therapeutic arrangement (1) and the sealing means (2) can be removed from the backpiece (3) and exchanged.
Claim 4
Dependent Claim
86 words
A holder according to claim 2, characterized by that the sealing means (2) comprises an elastomeric element (2) in a single piece, which includes said sealing ring (9) incorporating the sealing lip (13), in that the sealing ring on the part thereof remote from the sealing lip exhibits a diaphragm disk with a central hole (18) through which a stem part of the arrangement (1) is intended to pass, and in that the backpiece (3) is provided with holding means (6) for that stem part (5).
Claim 5
Dependent Claim
132 words
A holder according to claim 3, characterized by that the elastomeric component (2) is provided with- resilient means (17) compressible into resilient abutment with said backpiece, in that the centre part of said elastomeric component co-acts with the backpiece via first sealing means (15) inwardly of which the elastomeric component has at least one through-passing opening (11) for the provision of its front side with vacuum, at which front side outwardly of said opening (11) are arranged second sealing means (14) for sealing against the rear side of the diagnostic or therapeutic arrangement (1) when said sealing means (17) are in an uncompressed state, and the sealing effect of which is arranged to cease when the sealing ring (9) is moved towards the backpiece by the action of the resilient means (17).
Claim 6
Dependent Claim
