Description

The invention relates to an arrangement having a tablet computer unit with a tablet computer and a housing part of a medical imaging device.

A medical imaging device can in particular be operated by means of a tablet computer. In a medical examination that is carried out with the medical imaging device, it can be advantageous if the tablet computer can be attached to a housing part of the medical imaging device for certain examination steps and can be used detached from the housing part for other examination steps. In addition, it is advantageous if the tablet computer can be charged with electrical energy in a contactless manner while it is attached to the housing part.

The invention relates to an arrangement comprising

• - a tablet computer unit with a tablet computer and a first connection unit, which has a set of ferromagnetic areas,
• a housing part of a medical imaging device, the housing part of the medical imaging device having a casing and a second connection unit,
• - wherein the cladding has a recess in which the tablet computer unit can be positively received,
• - wherein the second connection unit is arranged in a region of the recess such that a magnetic connection can be formed by means of the first connection unit and the second connection unit, which counteracts the removal of the tablet computer unit from the recess.

• - dass die zweite Verbindungseinheit einen ersten Satz von magnetischen Bereichen aufweist, die voneinander beabstandet und der Vertiefung jeweils mit ihrem Nordpol zugewandt sind und die zusammen einen ersten magnetischen Fluss erzeugen,
• - dass die zweite Verbindungseinheit einen zweiten Satz von magnetischen Bereichen aufweist, die voneinander beabstandet und der Vertiefung jeweils mit ihrem Südpol zugewandt sind und die zusammen einen zweiten magnetischen Fluss erzeugen, und
• - dass ein absoluter Betrag des ersten magnetischen Flusses durch die Verkleidung in dem Bereich der Vertiefung im Wesentlichen gleich einem absoluten Betrag des zweiten magnetischen Flusses durch die Verkleidung in dem Bereich der Vertiefung ist.

It is intended

• - That the second connection unit has a first set of magnetic regions which are spaced apart from one another and each face the depression with their north pole and which together generate a first magnetic flux,
• - That the second connection unit has a second set of magnetic regions which are spaced apart from one another and each face the depression with their south pole and which together generate a second magnetic flux, and
• - that an absolute amount of the first magnetic flux through the casing in the region of the recess is substantially equal to an absolute amount of the second magnetic flux through the casing in the region of the recess.

In the context of this disclosure, the absolute amount of the first magnetic flux through the lining in the area of the recess is then in particular considered to be essentially equal to the absolute amount of the second magnetic flux through the lining in the area of the recess if the absolute amount of the first magnetic flux through the cladding in the area of the recess greater than 80 percent, for example greater than 90 percent, preferably greater than 95 percent, and less than 120 percent, for example less than 110 percent, preferably less than 105 percent, of the absolute amount of the second magnetic flux through the lining in the area of the recess.

In particular, the absolute amount of the first magnetic flux through the lining in the area of the recess is then essentially equal to the absolute amount of the second magnetic flux through the lining in the area of the recess, if the absolute amount of the first magnetic flux through the lining in the Area of the recess is equal to the absolute amount of the second magnetic flux through the lining in the area of the recess.

In particular, it can be provided that the first magnetic flux and the second magnetic flux together exert an adhesive force on the first connection unit when the tablet computer unit is received in the recess in a form-fitting manner. The amount of adhesive force can be greater than 100 grams, in particular greater than one kilogram, in particular greater than 10 kilograms, for example.

The second connection unit can, in addition to the magnetic areas of the first Set have further magnetic areas, each of which faces the depression with its north pole. In addition to the magnetic areas of the second set, the second connection unit can have further magnetic areas, each of which faces the depression with its south pole. In particular, an absolute amount of a magnetic flux through the cladding in the area of the depression, which all magnetic areas of the second connection unit, each facing the depression with their north pole, together generate, can be significantly greater or significantly smaller than an absolute amount of a magnetic Flux through the lining in the region of the recess, which all magnetic areas of the second connection unit, which face the recess with their south pole, together generate.

The fact that the absolute amount of the first magnetic flux through the lining in the area of the recess is substantially equal to an absolute amount of the second magnetic flux through the lining in the area of the recess causes the first magnetic flux and the second to be magnetic flux in the long-range effect essentially compensate each other and that the resulting effect of the first magnetic flux and the second magnetic flux on the first connection unit decreases very quickly with increasing distance between the first connection unit and the second connection unit.

The magnetic frictional connection therefore only takes place when the distance between the ferromagnetic areas of the first connection unit and the magnetic areas of the second connection unit is very small. As a result, until this very small distance is reached, the form fit between the tablet computer unit and the recess comes to the fore compared to the magnetic force fit. The tablet computer unit can thus be brought quickly and easily in the direction of the recess, optimally received in the recess and then fixed by the magnetic connection. The arrangement thus enables an improved combination of form fit and magnetic force fit for the holder of the tablet computer unit.
