Definitions
- This invention relates to a cushion for immobilizing a part of a body according to the preamble of claim 1.
- CT scanning involves the use of X-rays being passed through a body or through a part of a body to produce cross sectional images of body tissue.
- MRI involves the use of electromagnets and short bursts of powerful magnetic fields and radio waves.
- the document US 5,009,318 [1] discloses an apparatus for cushioning and maintaining an object by a device having a quantity of granular material.
- the apparatus comprises a retaining element defining a plurality of closed chambers, each chamber enclosing a portion of the granular material.
- a sealed housing made of material impermeable to gas encloses the retaining element.
- the paper EP 1 582 187 Bl [2] describes a hybrid immobilisation device comprising two parts, each of them made of thermoplastic material with different melting temperatures.
- the first part is shaped by heating in order to soften it so it becomes mouldable on the patients' body.
- the second part has the function of fixing the position of the first part with respect to the patents' body. The higher melting point of the material of the second part avoids deforming the second part while melting and moulding the first part with the lower melting point.
- the immobilization device for a lower leg according to WO 2006/110028 Al [4] has a pumping chamber and a flexible chamber with a fluid connection between the said chambers. During walking when the foot is lifted a fluid flows partly from the flexible chamber to the pumping chamber in order to apply a varying pressure to the lower leg. Obviously this device is only useable for legs.
- a castable sleeve including a proximal layer and a distal layer, the proximal layer contacting a portion of a patients' limb and
- the immobilizing device for immobilizing a part of a body according to WO 2008/086943 Al [6] surrounds / encases the hole part of said body. This device is not applicable for e.g. an immobilizing a head of a human being inside a MRI- System.
- the immobilization device is not applicable e.g. for a head.
- the object of the present invention is to overcome the problems presented by the above cited devices. There is a need for a device, which fulfils the following quoted
- Figure 2 perspective view of a cushion from the branch side
- FIG. 1 Figure 3 perspective view of a cushion from the rear side.
- the principle of a cushion 1 according to the present invention is depicted in FIG 1.
- the cushion 1 is sometimes also denoted by pad, a multipad or a universally applicable patient support and fixation system.
- the cushion 1 comprises functionally two chambers:
- the cushion 1 is produced with an upper foil 10, the membrane 6 and a lower foil 11 by welding.
- the three main components upper foil 10, membrane 6 and lower foil 11 are welded by a seam 8 along the border of the cushion 1, see FIG 2.
- the cushion 1 comprises preferably in its center part at least one cavity 4 made by welding one foil 10 or 12 with the membrane 6 within an area 12.
- These cavities 4 or holes 4 have advantageously a cylindrical form.
- the walls of said hole have a function of a ligament for the cushion 1.
- pairs of the cavities 4 are arranged opposite the membrane 6.
- the upper foil 10 the upper foil 10
- the cushion may have a recess 5. At this side with the recess 5 - but a recess 5 is not required - there is a notch 9 or branch 9 for connecting a tube. This notch is connected with the air chamber 3.
- an external hand pump (not shown in the figure) connected via a tube the air chamber 2 receives pressured air in order to be expanded by a pressure P.
- This pressure P affects also on the chamber 2 filled with granular material.
- the hand pump allows an appropriate pressure of the cushion. Appropriate in the sense, pressure is still comfortable for the patient and the pressure allows an effective immobilization of a part of a body, e.g. within a MRI-tube.
- the chamber 2 filled with granular material is put on the side of the patient or a part of the body of the patient whereas the air chamber 3 is put on the side of the medical device as e.g. a MRI coil or a CT (e.g. head) holder.
- the chamber 2 with the granular material fits by the pressure of the air chamber 3 is perfectly to the topology of the part of a body. Further by the pressure of the air chamber 3 to the part of a body via the chamber 2 the pearls become rigid.
- the chamber 2 When the air chamber 3 is filled with pressured air or being removed from pressured air, the chamber 2 filled with granular material moves accordingly.
- the chamber 2 has a plurality of ventilation holes 7 for the flux of air. It must be pointed out; there is no connection of air flux between the two chambers 2 and 3, since they are separated by the membrane 6.
- these ventilation holes 7 are arranged along the border of the chamber 2, see FIG 2 and FIG 3.
- the cushion 1 has preferably a cuboid form with rounded edges.
- the granular material in chamber 2 is of hundreds of tiny balls or pearls.
- the materials used for the cushion 1 may be chosen as follows :
- the upper and lower foil as well as the membrane are preferably made by polyurethane .
- the granular material is of EPS.
- EPS as well as the PUR-foils have low X-Ray- coefficients .
- a cushion with the before mentioned components does not impact the quality of the MRI- or CT-images.
- immobilization device for immobilizing a lower leg, pressure device apparently suitable for use in the immobilization device, and method for manufacturing the pressure device
