Definitions

  • the present invention is directed to a support system for patients and to a support mem- ber for such a support system.
  • Radiotherapy For various types of medical procedures, patients need to be positioned during extended periods of time. Medical procedures that require such prolonged positioning include some types of medical imaging as well as medical treatment, such as e.g. radiotherapy.
  • prolonged positioning of patients in practice often turns out to be problematic, in particular (but not only) for individuals who suffer from general physical weakness.
  • extended periods of immobilization often cause severe discomfort or even pain. This in particular holds true for some types of radiotherapy, where patients have to be positioned and aligned in a semi-reclined position in order to obtain accurate position- ing and alignment of the part of the body to be treated with respect to the radiotherapy system.
  • US2008/0052829 A1 was published on 06.03.2008 on behalf of Goudriaan Bram De Vries and shows a reclining table comprising a stationary reclining plate and a back rest that is pivotally connected to it.
  • Such types of reclining tables are e.g. used for radiotherapy of organs in the thoracic region, such as of the breast.
  • the reclining table comprises means to fix the back rest in various angular positions.
  • the upper part of the body of a patient arranged on the reclining table can be positioned and aligned in a specified way.
  • the transition region between the stationary reclining plate and the back rest in some cases turns out to be uncomfortable for the patient, depending on his/her anatomy and physical condition. So far, one tries to improve the patient's comfort by cushioning the transition region with foam material. However, in many cases such cushioning does not increase patient comfort sig- nificantly. In addition, using foam material often leads to an increased mobility of the part of the body supported by it, which in many cases interferes with the medical procedure. As well, in order to provide support for multiple patients with various anatomies multiple types of cushions are needed. As well, use of such cushions makes cleaning of the reclining table more time consuming.
  • DE4423755 A1 was published on behalf of GDW Genossenschaft der josen fur Behinderte eG and shows an apparatus for the fixation and positioning of a part of the body.
  • the document discloses an apparatus that can be used as seat rest for a sitting or a reclining furniture, in particular for a wheelchair.
  • This apparatus comprises a bag filled with a filling material which comprises a plurality of bodies that are movable relative to each other.
  • the bag can be evacuated using a vacuum pump, leading to a restriction of said movement leading to a dimensionally stable bag.
  • a cushion layer is arranged between said bag and the body.
  • Said cushion layer is a bag that can be filled with air in order to bring it in a lasting extended state.
  • the bag filled with a filling material has to be manually adjusted in order to fit the shape of the part of the body it has to be applied on.
  • the bag filled with filling material is evacuated, leading to shrinking of the bag and hence also to an improper alignment of the contour of the evacuated bag with respect to the body contour.
  • the evacuated bag becomes relatively hard which - due to the improper alignment and resulting points of contact - typically causes pain to the patients when being positioned on it over extended periods of time.
  • the bag filled with air is arranged between the evacuated bag and the body and is expanded, in order to fill the void space between the evacuated bag and the body caused by the evacuation of the other bag.
  • EP2104477 B1 was published on 30.09.2009 on behalf of ETH Zurich and shows an immobilizing device for a part of the body, in particular for the forearm.
  • the immobilizing device comprises a bag and an outer shell in which the bag is mounted. Between the outer shell and the bag, a hollow space is formed for receiving pressured air in order to produce a force on the bag for immobilizing a part of the body.
  • the bag is filled with granular material and adapted to be put over the part of the body.
  • WO2012/076199 A1 was published on 14.06.201 2 on behalf of Pearltec AG and shows a relatively small cushion with an elongated shape for immobilizing a part of the body.
  • the cushion disclosed comprises an air chamber and a chamber filled with granular material.
  • the two chambers are separated by a membrane.
  • a hand pump pressured air can be pumped in the air chamber, leading to an expansion of the air chamber.
  • the chamber filled with granular material is placed between the part of the body and a medical device - such as a MRI-coil or a CT-holder.
  • the air chamber is filled with pressured air, causing the granular parts in the other chamber to become rigid, as well as a movement of the chamber filled with granular material is caused.
  • the chamber filled with granular material has a plurality of ventilation holes for the flux of air.
  • Such types of cushions are suited for immobilizing some parts of the body with respect to medical devices, such as coils.
  • One object of the present invention is to provide a support system for patients (human and animal) which in particular also allows to obtain an easy and more comforta- ble/ergonomic support of patients in a reclined - or semi-reclined - position during medical procedures.
  • a support system according to the present invention a patient may be supported in a dorsal position, a ventral position or in a lateral position. However, it is not limited to such positions.
  • Another object of the invention is to provide a support member for such a support system.
  • the invention is inter alia based on the finding that patient discomfort during extended periods of positioning can be caused by fatigue of muscles, tendons or ligaments which leads to critical displacements of certain parts of the body. For example, in case of reclining tables, prolonged positioning in reclined or semi-reclined positions typically leads to lowering movements and a rotation of the pelvis and/or the lumbar spine. This may lead to higher internal postural stress and hence e.g. cause lower-back pain. At the same time the altered posture typically leads to increased contact stress between the body and the support device.
  • a support system typically comprises a support board designed such that a part of the body of the patient can be mounted on said support board.
  • the support system furthermore comprises a support member arranged to mechanically support the part of the body, and which comprises a first cushion.
  • the support member comprises an inflat- able second cushion arranged at least partially between the support board and the first cushion, foreseen to press the first cushion away from the support board against the part of the body to be supported.
  • the first cushion is designed to switch from a more deformable state to a less deformable state and thereby to facilitate (respectively support) the support of the part of the body.
  • the part of the body When the part of the body is mounted on the support system, the part of the body may be pressed on the support board and/or the support member by gravity. Alternatively or in addition the part of the body may be pressed on the support board and/or the support member by means of e.g. a fixation device, such as e.g. a belt.
  • the first cushion is designed to reversibly switch from a more deformable state to a less deformable state. Hence, such a variation allows multiple use of the first cushion.
  • the filling material may be a liquid or gel, such as a non-Newtonian fluid, in particular a dilatant fluid.
  • the filling material comprises an electrorheo- logical fluid, in particular an electrorheological liquid.
  • an electrical field may be applied in order to switch the filling material to a less deformable state.
  • the filling material comprises a magne- torheological fluid, in particular a magnetorheological liquid.
  • a magnetic field may be applied in order to switch the filling material to a less deformable state.
  • the filling material is an interlockable material that when compressed interlocks and thereby achieves a less deformable state.
  • the filling material may be an interlockable material that interlocks and thereby achieves a less deformable state when the first chamber is evacuated.
  • the support system may comprise a pump in order to at least assist evacuating of fluid from the first chamber. Thus, compaction of the first chamber may be supported.
  • the filling material is a granular material whose granules are configured to interlock with each other when being compressed.
  • the granules (granular base material) inside the first chamber are compressed against each other and hence interlock such that the first cushion forms some kind of rigid shell that closely aligns with the contour of the part of the body to be supported.
  • the first cushion forms some kind of rigid shell that closely aligns with the contour of the part of the body to be supported.
  • the granular material may be at least partially made from expanded polypropylene (EPP) .
  • EPP expanded polypropylene
  • the first cushion can adapt easily to the outer contour of the body, while the granules are still able to interlock reliably with each other if compressed by forces of a magnitude typically obtained in patient support.
  • Good interlocking may be obtained if the granular material is made from expanded polystyrene (EPS).
  • EPS expanded polystyrene
  • EPP expanded polypropylene
  • the support board may e.g. be - or may be part of - a stretcher or a surgical table. It may be a plate-like structure or comprise multiple plate-like structures - such as multiple plate-like portions interconnected by a grid.
  • the second cushion may comprise an inner second chamber to which fluid can be added in order to inflate the second cushion e.g. by a pump. Thus, an evenly distributed force can be applied on the first cushion which facilitates a good support of the part of the body.
  • Fluid may e.g. be a gas (such as air) or a liquid (such as water).
  • the second cushion may comprise a fluid connector to which a fluid line (e.g. a tube) can be interconnected in order to add fluid to the second chamber or evacuate fluid from the second chamber.
  • the second chamber is fluidically interconnected an automated pump.
  • the second chamber may be interconnected with a pressure gauge for measuring the fluidic pressure inside of the second chamber.
  • the pressure gauge may be connected to a display that pro- vides information about said pressure.
  • the pressure gauge may also be used in order to control an automated pump - as described above.
  • the support member may also comprise means limit the maximum fluidic pressure inside of the second chamber, as e.g. a pressure relief valve. Such a means may be used in order to restore a pressure setting of a previous supports to prevent injuries due to mechanical overloading of the part of the body, as e.g. caused by suppression of blood flow.

  • parts of the body that have a curved outer contour can be supported in an easy and ad- vantageous and reliable manner, as will be explained in more detail below.
  • relatively large supportive contact interfaces between the support member and the body can be established. This allows to distribute contact forces and hence reduce contact stress concentration in the body.
  • parts of the body that cannot be supported by conventional systems due to e.g. a concave con- tour of the body - such as the lordosis - can be supported by the support system according to the present invention if desired.
  • the second cushion may be configured such that it can be inflated to a thickness that is sufficient in order to displace the first cushion until it presses against the part of the body.
  • the first cushion when pressed against the body, forms a rigid cast-like shell which helps to maintain the shape of the anatomical region over time.
  • it may form some type of positive locking interaction between the support member and the part of the body.
  • the support system comprises a third cushion arranged at least par- tially between the first cushion and the part of the body to be supported.

  • the first and the second fluid connectors 32, 32' can be fluidically interconnected with each other, while the third fluid connector 32" may be connected to an air pump in order to provide fluid to the two second chambers 31 , 31 ' and consequently inflate the second cushions 30, 30'.
  • the first support member 1 0 comprises passages 14 that are arranged as described above with respect to Figs.
  • the second support member 1 0' comprises passages 14' that are arranged at the base face of the triangular prism, which ensures good exchange of air.
  • the passages 14, 1 4' fluidically interconnect the first chambers 21 , 21 ' with the atmosphere.
  • the first support member 1 0 has an essentially planar shape, while the second support member 1 0' is essentially formed like a triangular prism, which allows them to provide good support of the pelvic and lumbar region, as illustrated in Fig. 9.
  • the first and the second cushions 20, 30 of the first support member 1 0 are arranged similar to parallel layers.
  • the first and the second cushion 20', 30' of the second support member 1 0' are arranged in a different way, the second cushion 30' extending along two lateral faces of the triangular prism geometry, whereas the first cushion 20' extends along the other lateral face.
  • Such a variation turned out to provide a very reliable support to the pelvis when the second cushion 30' is being inflated.
  • the second cushion 30' may also extend along one lateral face only.

  • the parts of the support members 1 0, 1 0' that come into direct contact with the patient 2 can be easily cleaned - respectively disinfected - without the risk of cleaning agent (respectively disinfectant) entering inside of the support member 1 0, 1 0' through the passages 1 4, 1 4'.
  • the carrier means 1 3 is made from a flexible material, a good alignment of the carrier means 1 3 - respectively the support members 1 0, 1 0' - to the support board 3 as well as to the patient 2 becomes possible, as schematically indicated in Fig. 9.
  • Figs. 10 to 13 schematically explain in consecutive steps how a part of the body 2 is supported using a support system 1 according to the present invention.
  • the second cushion 30 is typically still relatively flat, respectively the second chamber 3 1 is not inflated yet.
  • the first chamber 21 of this embodiment of the invention is partially filled with a granular material 22 comprising spherical particles of expanded polystyrene.
  • the first and the second chamber 21 , 3 1 are separated by a single membrane which forms the front wall of the second cushion 30 and at the same time the rear wall of the first cushion 20.
  • the first cushion 20 starts to deform and align with the outer contour of the part of the body 2 as soon as the part of the body 2 gets in contact with the support member 1 0 and starts to press against the first cushion 20. Consequently, the shape of the first cushion 20, respectively the first chamber 21 is changed, leading to moving and compaction of the granular material 22, as shown in Fig. 12. At the same time, the first cushion 20 starts to exert a distributed force (indicated by the small arrows) on the part of the body 2. All walls of the first and of the second cushion 20, 30 are made from a fluid-tight material.
  • the second cushion 30 is inflated by adding fluid (e.g. air) to the second chamber 31 in the second cushion 30, as shown in Fig. 13. This causes an increase of the mean thickness of the second cushion 30 and thus the first cushion 20 being pressed against regions of the the part of the body 2 which before were not in contact with the support member 1 0.

Abstract

L'invention concerne un système de support (1) pour un patient (2) comprenant une planche de support (3) conçue de sorte qu'une partie du corps du patient (2) puisse être montée sur ladite planche de support (3). Le système de support (1) comprend en outre un élément de support (10, 10') disposé pour supporter mécaniquement la partie du corps (2) et qui comprend un premier coussin (20, 20'). L'élément de support (10, 10') comprend un second coussin gonflable (30, 30') disposé au moins partiellement entre la planche de support (3) et le premier coussin (20, 20'), prévu pour presser contre le premier coussin (20, 20') et l'éloigner de la planche de support (3) contre la partie du corps (2) à supporter. Le premier coussin (20, 20') est conçu pour passer d'un état plus déformable à un état moins déformable et, ainsi, faciliter le support de la partie du corps.
