- At least or exactly a first material is made or has at least a first material.
- the wall of the pressure vessel limits its interior. Under the interior of the pressure vessel according to the invention that space or that volume understood, which / s by the
- Specified geometry of the pressure vessel or comprises or circumscribed by an outer wall of the pressure vessel.
- the pressure vessel is cylindrical, the interior of the pressure vessel is that of the cylindrical one
- the space of the interior is defined by the result of the multiplication of height, width and depth of the rectangle. It does not matter in determining the interior whether or not the space corresponding to the interior is fluid-tightly confined.
- the interior does not describe a fluid-tight closed space, but a volume circumscribed by the wall. That space which does not belong to the interior of the pressure vessel is referred to herein as its exterior.
- the pressure vessel has an insertion opening, through which the limb stump (in this context, the distal end of the stump can always be meant
- the insertion opening can be, for example, an open end face or end plane, a passage opening in the wall or an opening which breaks through or interrupts the wall. In the area the insertion opening, the interior is thus not separated by a portion of the wall of the exterior of the pressure vessel.
- the insertion opening may lie in an inlet opening or in an introduction plane through which the
- the pressure vessel has at least one or exactly one fluid-tight membrane.
- the membrane is made of a second material or has such.
- the first and second materials are different.
- the wall is one-piece or optionally multi-piece
- a multi-part wall can have several
- the medical device with the multi-part wall according to the invention can be used as a mobile medical
- the device according to the invention optionally has at least one adhesive sock or one
- the adhesive stocking thus connected to the body stump or the sensor assembly resting on the body stump optionally has sensors for Preparation of a data model.
- the device according to the invention has no adhesive stocking, or it has a Haftstrumpf, but does not have sensors.
- the set according to the invention has at least one
- the medical device also has at least one transmitting device and / or one
- Receiving device for transmitting and / or receiving
- Signals of the sensors which are arranged in the adhesive stocking or in the sensor arrangement.
- the method according to the invention serves to produce a data model of a limb stump.
- a medical device according to the invention is provided.
- the method comprises the step of detecting signals of the adhesive sock or the sensor arrangement.
- the adhesive stocking or the sensor arrangement according to the invention is provided and / or prepared for coating over a limb stump (KS) during the preparation of a data model of the limb stump (KS).
- the pressure chamber is filled with a liquid, a balloon-like closed
- Membrane provided inside the pressure vessel or the liquid level within the pressure chamber so
- the membrane is covered by liquid at least in sections thereof around the entire circumference of these sections, or over the
- Embodiments of each of the aforementioned subject matters may include one or more of the following have characteristics mentioned in any combination, unless a specific combination for the skilled person as obviously technically impossible to recognize. Also the
- An adhesive sock may in some of the invention,
- Body stump both to cover the circumference of the Haftstrumpfs as well as along its length continuously or completely.
- the pressure vessel and / or the fluid-tight membrane may be connected to the pressure vessel and / or the fluid-tight membrane as described by the present applicant under DE 10 2016 101 257.2 entitled "Device, Adapter, System and Method for
- the pressure chamber is a closed and / or lockable space in which the fluid can be exposed to a pressure above atmospheric pressure (in short: atmosphere) without being able to escape from this space.
- atmospheric pressure in short: atmosphere
- the membrane is arranged around the
- Pressure chamber is.
- the membrane serves to, on its own (eg in the form of a balloon) or alternatively together with portions of the wall, at least partially or completely in the interior of the pressure vessel,
- this fluid chamber is referred to herein as a pressure chamber.
- fluid chamber and "pressure chamber” are interchangeable in certain exemplary embodiments according to the invention and / or in those embodiments in which there is no technical objection to those skilled in the art. What is referred to herein as the "pressure chamber” may also apply to a "fluid chamber.”
- the pressure chamber is then within the interior of the pressure vessel when the pressure prevailing in the pressure chamber does not exceed a certain pressure.
- the pressure chamber differs from this in certain exemplary embodiments according to the invention also to the exterior of the pressure vessel when the pressure prevailing in the pressure chamber acts on the membrane in such a way that the latter bulges forwards through the introduction opening, ie into the exterior of the pressure vessel ,
- the pressure chamber may thus have a variable volume, which depends on the pressure prevailing in the pressure chamber. The latter does not apply to the constant interior of the pressure vessel.
