Abstract

A support for a medication cartridge provided with one or more electronically readable items of information carrying areas is disclosed. The support disclosed has a number of closely spaced mutually electrically insulated conductors embedded in an electrically insulating material. The support is useful in assisting reading the item of information stored on the outside of the medication containing cartridge.

Claims

1. A support for a cartridge with one or more electronically readable items of information carrying areas, wherein the support for the cartridge is at least partially constituted by one or more electrically connecting supports, each comprising a number of closely spaced mutually electrically insulated conductors embedding in an electrically insulating material that stretches from one supporting surfaces of the cartridge to a contact area for receiving and transferring the information, when the cartridge is position in the support and wherein each of the electrically connecting supports is constituted by alternating layers of electrically conducting material of maximum thickness T_cl and electrically insulating material of maximum thickness T_il, respectively.

2. A support for a cartridge provided with one or more electronically readable items of information carrying area, wherein the support is at least partially constituted by one or more electrically connecting supports, each comprising a number of closely spaced mutually electrically insulated conductors embedded in an electrically insulating material that stretches from one of the supporting surfaces of the cartridge to a contact area for receiving and transferring the information, when the cartridge is positioned in the support and wherein he cartridge has an axis of symmetry and the contact area comprises a group of identical and regularly spaced electrically conducting pad of width Wcp in the direction of adjacent pads, the adjacent pads being separated by an electrically insulating area of width Diacp and the following relations between said distances are fulfilled:

Diacp>

2*Til+Tcl.

3. A support for a cartridge provided with one or more electronically readable items of information carrying area, wherein the support is at least partially constituted by one or more electrically connecting supports, each comprising a number of closely spaced mutually electrically insulated conductors embedded in an electrically insulating material that stretches from one of the supporting surfaces of the cartridge to a contact area for receiving and transferring the information, when the cartridge is positioned in the support, wherein the cartridge has an axial direction of symmetry and the cartridge is provided with a plurality of rectangular, essentially parallel, identically sized information carrying areas of height Hica in the direction of the circumference of the axis of symmetry, the information carrying areas being spaced with equal mutual distance Dica along the periphery of the cartridge in the direction of a circumference of the axis of symmetry and the supporting means comprising two rectangular, essentially parallel, identical electrically connecting supports of height Hctm in the direction perpendicular to the axis of symmetry of the cartridge, separated by an electrically insulating volume of width Dctm between the two electrically connecting supports and satisfying the following relationship between the distances:

Hica<

Dctm<

2*Hica+Dica, and Hctm<

Dica<

2*Hctm+Dctm.
