Definitions

  • the invention relates to a positioning aid for positioning patient body parts, in particular relative to a medical treatment or diagnostic device or device part, such as a measuring coil of an MRI scanner.
  • Magnetic resonance tomographs are increasingly being used today in the context of modern medical diagnostic technology.
  • Measuring coils which are in the form of ring coils, surface flex coils or the like, are used to examine extremities such as arms and legs. on a part of the body to be examined, e.g. an arm or a leg, pushed on or on a part of the body to be examined, e.g. the torso, shoulder or neck.
  • the part of the body to be examined should not move relative to the measuring coil during the measuring process. This is quite difficult since the scanning or measuring time of an MRI scanner is usually in the range of 30 to 45 minutes. During this long period, the body part to be measured must be kept free of blurring so that a sufficiently good and thus diagnosable representation of the body part to be examined is achieved.
  • Such a tripod device works well because it allows the body part to be examined to be kept very calm even over a long period of time.
  • the invention has for its object to make a positioning aid of the type specified available that a long-term enables a calm positioning of a part of the body to be examined in a relatively simple, inexpensive and convenient and comfortable manner for the patient.
  • the solution consists in a positioning aid in the form of a gas-tight shell partially filled with particles, which is coated on the outside with waterproof, water-vapor-permeable material or consists of such material. In the latter case, material is used that is gas-tight despite permeability to water vapor. Microporous polytetrafluoroethylene (PTFE) is a particularly suitable material for this.
  • PTFE polytetrafluoroethylene
  • the waterproof, water vapor-permeable material can be provided on the outside with a knitted textile, which increases the comfort when using the positioning aid and protects the material from the outside.
  • the volume of the shell constructed with gas-tight material and coated with waterproof, water-vapor-permeable material or consisting of such material can be changed by more or less large gas inclusion.
  • the casing is provided with a mouthpiece with a closing valve for supplying or extracting gas into or from the casing.
  • the envelope is filled with small particles to a particle fill volume that is a predetermined fraction of the maximum inflation volume of the envelope. These are of such a small size that they allow the at least partial, form-fitting immersion of the body part to be stored when they are lying loosely against one another. Their surfaces have such a surface friction factor that, when the casing is evacuated to approximately the particle filling volume, they essentially retain their positions which were assumed before the evacuation.
  • the particles preferably consist of small plastic spheres.
  • the patient places the body part to be examined on the outside of the envelope. Since the particles are easily movable relative to one another with this degree of filling of the shell, the body part to be examined sinks at least partially into the cushion, similar to if the body part to be examined were placed in a pile of sand.
  • the shell is then connected to a suction device via the mouthpiece with the closing valve and evacuated down to approximately the particle filling volume. Because of this evacuation, the particles are pressed together by the shell, similar to how they would be pressed together by means of a shrink film.
  • the particles Due to their surface friction and this shell pressure, the particles essentially retain those positions which they have assumed after the body part to be examined has been placed on the shell which has not yet been evacuated. The previous state is frozen by the evacuation.
  • the evacuable sheath thus acts practically like a shrink film, the state of shrinkage of which can be removed by later gas inlet into the sheath.
  • this positioning aid corresponding to the contour of the body part to be examined is also retained.
  • the body part to be examined can therefore remain in this immersion form for a long time, which is optimally adapted to the outer contour of this body part. This means that this part of the body can be held immovably on this positioning aid even for a period of time which is required for measurement by means of an MRI scanner.
  • the invention has thus made available a positioning aid for body parts to be subjected to magnetic resonance imaging, which ensures safe immobilization of the body part to be examined even for a relatively long time, is inexpensive to manufacture, does not need to be arranged firmly on the patient table and does not require any modification during use differently dimensioned measuring coils are required. Because an essential part of the body part to be examined on this positioning aid can rest and since sweat liquid can be drained off due to the covering or construction of the casing of the positioning aid with waterproof, water vapor-permeable material, this represents a particularly convenient positioning aid. Because of this material, this positioning aid can also be washed without problems and thus kept clean.
  • PTFE Microporous stretched polytetrafluoroethylene
  • stretched PTFE provided with hydrophilic impregnating agents and / or layers as described in US Pat. No. 4,194,041
  • breathable polyurethane layers or elastomers such as copolyether esters and their laminates as described in U.S. Patents 4,725,481 and 4,493,870.
  • This positioning aid can be used not only for the temporary storage of parts of the body to be measured in connection with magnetic resonance imaging, but also, for example, in connection with X-ray devices, other diagnostic devices or only as a temporary or permanent positioning aid for patient positioning.
  • a molded part with a shape corresponding to the wound site can be placed on the positioning aid in the non-evacuated, that is to say moldable, state and its shape impression can be saved in the positioning aid by evacuation.
  • the patient can be positioned on the positioning aid in such a way that his wound site is positioned over the position of the shape impression of the positioning aid. This prevents lying on the wound or wound site.
  • the positioning aid according to the invention can also be successfully used in the operation area.
  • the location of the patient to be operated on can be fixed by means of the positioning aid as desired and according to changing requirements, without many different pillows, in particular wedge pillows, being required for this.
  • a conventional pillow is produced by sewing two parts of the cover together on their inner sides and then turning them inside out. The edges are thus inside the pillow. The still open side is closed by a zipper or the like. However, this is not possible with a vacuum cushion as used for the positioning aid according to the invention.
  • Conventional vacuum cushions are made by welding two layers of PVC on the outside.
  • the welded edges on the outside are disruptive from an aesthetic point of view.
  • dirt can collect in it, which is undesirable from a hygienic point of view.
  • FIG. 1 shows a positioning aid 11 according to the invention, which has a gas-tight shell 13 coated with micro-porous PTFE, within which there are a large number of small parts, in particular plastic balls 15. these plastic beads 15 are only filled up to a fraction of the maximum inflation volume of the envelope 13.
  • the casing 13 is provided with a mouthpiece 17, by means of which gas can be sucked out of the casing or gas can be let into the casing.
  • a closing valve which prevents gas flow through the mouthpiece 17 at least in the evacuated state of the positioning aid, as long as the closing valve is closed.
  • An arm and a hand 19 of a patient to be examined are shown placed on the positioning aid 11 and partially immersed.
  • the positioning aid is shown in the figure in the state in which it has been evacuated after placing the arm and hand 19 on it.
  • the plastic spheres 15 fill the casing 13 roughly, which in the state shown has been evacuated to approximately the particle filling volume and, in this evacuation state, acts like a shrink casing.
  • the plastic beads 15 are therefore "frozen” in the envelope 13 with respect to their assumed position during the evacuation state and retain this position until gas can flow into the envelope 13 again through the mouthpiece 17 and the freeze or shrink envelope state is canceled again.
  • a measuring coil (not shown) of an MRI scanner can be placed around the associated upper arm, for example, in order to carry out a nuclear sprint tomographic measurement on the upper arm.
  • FIGS. 2 and 3 show an inner valve part 21 and an outer valve part 23 of a valve system, as is preferably used for the positioning aid 11 according to the invention.
  • the inner valve part 21 comprises a cylinder 25 open at both ends, at the lower end of which a cylinder flange 27 is provided in FIG.
  • the casing 13, which is only indicated in FIG. 2, has a perforating hole (not shown) with a diameter which is approximately as large as the inside diameter of the cylinder 25. By means of the cylinder flange 27, the inner valve part 21 is welded gas-tight onto the inside edge of this hole.
  • a hose passage opening 31 is introduced, into which a hose can be inserted, through which air or another gas can be let into the casing 13, for example pumped into it, or can be suctioned out of the casing 13.
  • the entire casing 13 can be turned inside out through the cylinder opening 29 in such a way that the outside of the casing 13 is then outside at all points and all the welding edges of the casing 13 are now on the inside of the casing.
  • the cylinder 25 and the cylinder flange 27 are also on the inside of the sleeve 13.
  • the outer valve part 23 has the shape of a cylinder, on the lower end of which in FIG. 3 an outer valve part flange 35 is provided.
  • the outer valve part flange 35 By means of the outer valve part flange 35, after turning the cushion inside out, the outer valve part 23 is welded in a gas-tight manner onto the outer edge of the hole perforating the casing 13 in such a way that an inner opening 37 of a passage passage 39 passing through the outer valve part 23 is aligned with the through opening 33 of the inner valve part 21.
  • the passage passage 39 preferably has approximately the same diameter as the cylinder 25 of the inner valve part 21.
  • the passage passage 39 of the outer valve part 35 is angled and an outer opening 41 of the passage passage 39 opens into the open on the cylinder circumference of the outer valve part 23 .
  • the small parts, preferably plastic balls 15, which are arranged inside the casing 13 of the positioning aid 11, can be introduced through the through opening 33 of the inner valve part 21. After the cover 13 has been turned inside out, they are filled in through the passage opening 33.
  • the outer valve part 35 is welded onto the outside of the cover 13. Via the passage passage 39 of the outer valve part 35 and the passage opening 33 of the inner valve part 21, there is a ventilation duct from the outside into the interior of the casing 13.
  • a hose 43 is passed through the passage passage 39 and the passage opening 33 and has an inner end 45 opening into the interior of the casing 13 and an outer end 47 protruding from the outer opening 41 of the outer valve part 35.
  • the outer end can be permanently or temporarily connected to a pump / suction device (not shown) in order to bring the positioning aid 11 into the formable state or the state with a fixed shape, as desired.
  • the positioning aid 11 In applications in which the positioning aid 11 is used in a constant place of use, it can be advantageous to permanently connect the hose 43 to a pump / suction device. In this way, the ventilation processes and the evacuation processes can each be carried out very quickly, which is advantageous in the case of a rapid change of patients. In addition, the permanent connection of the hose 43 to the pump / suction device can compensate for a vacuum loss which can arise due to imperfect sealing of the casing 13.
  • the inner end 45 of the hose 43 is inserted into the hose passage opening 31 and is held by the side walls. This ensures a relatively firm hold of the inner end 45 of the hose 43.
  • FIG. 5 shows an embodiment in which a closing valve 49 is arranged in the passage 39. This can be opened by inserting a hose (not shown in FIG. 5) through the outer opening 41 into the passage 39 through the closing valve 49 constructed with closing lamellae, so that the positioning aid 11 can be vented or evacuated.
  • a closing valve 49 is arranged in the passage 39. This can be opened by inserting a hose (not shown in FIG. 5) through the outer opening 41 into the passage 39 through the closing valve 49 constructed with closing lamellae, so that the positioning aid 11 can be vented or evacuated.
  • the passage opening 33 of the inner valve part 21 and / or the passage passage 39 of the outer valve part 23 can be provided with a sieve-like grille (not shown). This can be arranged, for example, at the location of the closing valve 49 or, if this is not required, in its place.
  • the outer opening 41 of the outer valve part 35 can also be provided with an extension piece which can be connected to a conventional pump, such as is used for example for inflating bicycle tires, air mattresses or the like.
  • a conventional pump such as is used for example for inflating bicycle tires, air mattresses or the like.
  • the positioning aid 11 can be ventilated or evacuated by means of such a pump.
  • the outer opening 41 can also be closed with a closure element (not shown in FIG. 5), for example in the form of a plug which fits into the outer opening 41.
  • FIG. 6 shows an embodiment in which a closure element in the form of a cap part 51 is used.
  • This has the shape of a cylinder which has an inner blind hole 53, the inner dimensions of which correspond to the outer dimensions of the outer valve part 23.
  • the cylinder height of the cap part 51 is chosen so high that it completely engages over the outer opening 41 when it is completely fitted onto the outer valve part 35.
  • the inner blind hole 53 is preferably dimensioned such that the cap part 51 sits in a gas-tight press fit on the outside of the outer valve part 35.
  • the cap part 51 can either be used instead of the closing valve 49 or in addition to it. In the latter case, a particularly good valve closing effect is obtained.
  • an (essentially) gas-tight gluing can also be carried out.
  • the cylinder parts of the two valve parts 21 and 23 extend to opposite sides of the envelope region located between their cylinder flanges 27 and 35.
  • the cylinder flange 27 of the inner valve part 21 has been fastened to the inside of the sleeve 13 which is turned outwards, not only the sleeve 13 is turned back through the through opening 33 of the inner valve part 21 but also the cylinder 25 of the inner valve part 21 is thereby Cylinder flange 27 slipped through, after which the cylinder is on the other side of the cylinder flange 27 than before.
  • FIG. 2 shows the outside of the turned-back sleeve 13, the cylinder flange 27 located after the turning back on the inside of the sleeve 13 and the cylinder 25 of the inner valve part 21 protruding from the outside of the turned-back sleeve 13 and thus from the outside of the positioning aid
  • the outer valve part 23 is then plugged onto this cylinder 25 of the inner valve part 21, which protrudes from the outside of the sleeve 13, in the exact orientation as shown in FIG. 3 with reference to FIG. That is, for the plugging of the outer valve part 23 onto the cylinder 25 of the inner valve part 21, the two figures 2 and 3 can be imagined as a single figure.
  • the cylinder area of the outer valve part 23 can consist of solid material into which the passage 39 is incorporated, e.g. in the course of an injection molding process.
  • the cylinder area of the outer valve part 23 can be made hollow like a cylinder hat and the passage 39 can be formed in the interior thereof with the aid of a tube or hose.
  • the outer diameter of the cylinder 25 of the inner valve part 21 and the inner diameter of the passage passage 39 of the outer valve part 23 are preferably matched to one another in such a way that the passage passage 39 receives the cylinder 25 in a snug fit or even in a press fit.
  • passage opening 33 receives the passage passage 39, it is possible to provide a correspondingly opposite reciprocal dimensioning of the passage opening inner diameter and the passage passage outer diameter.
  • the hose passage opening 31 in the cylinder wall of the inner valve part 21 can be used to receive a part of the outer circumference of the part of the passage 39 which is horizontal in FIG. This makes the overall height the inner valve part 21 and outer valve part 23 having valve arrangement is reduced.
  • the casing 13 of the positioning aid 11 can additionally be provided with a foam covering on its outside. This results in a better pressure distribution, for example when the head of a patient is lying on the positioning aid 11. In this way, an optimal head adaptation can be achieved in comparison with a foam cushion made entirely of foam material and there is uncomfortable pressure on one side of the head, as can occur with a foam cushion. avoided.
  • the positioning aid according to the invention can therefore also be used advantageously as an (orthopedic) pillow, not only for sick people but also for healthy people who want to achieve optimal support for their head and cervical vertebrae while lying down.
