Definitions

  • the present invention relates to a support device according to the preamble of claim 1 .
  • a support device is disclosed in SE-C-512 063.
  • a plurality of such support devices are known, these particularly being arranged to permit the insertion of a bowl or the like below a person resting on the support device in order to permit said person to relieve himself or herself by means of said bowl while being supported by the inflatable portion on which the person may lay or sit.
  • such devices are provided to be used in the medical service where the persons being treated often have substantial difficulties in moving themselves in order to relieve themselves, and where, accordingly, it is up to the personnel to move and position such patients, which are often bound to their beds, in order to make them able to relieve themselves in a bowl, a so called basin, which in its turn is positioned on the bed.
  • Known support devices such as those disclosed in US-A-3 935 604 and US-A-4977 629, comprises a recess in the inflatable portion, into which recess the bowl, i.e. the basin, may be brought into a position below a person resting on the inflatable portion and lifted by the latter as it is in its inflated state.
  • the inflatable portion gives a comfortable support to the patient as the latter is lying or sitting on the basin and is to relieve himself or herself. This aspect is also important in order to provide for the physical and psychological health of the patient.
  • the support device When the inflatable portion is in its evacuated inactive state, it is desired that the support device is positioned as plane and flat as possible along the surface of the base member, in order to avoid the person or the patient from experiencing any discomfort due to the presence of the support device.
  • Support devices according to prior art take this into consideration by being formed by relatively thin layers of a material that enables them to better follow the outer shape presented by the base member as the patient takes different positions thereon, se for instance the above-mentioned SE-C-512 063.
  • FR-A-2656795 discloses a support device, which includes an inflatable portion with a first lower flexible material layer and an upper material layer. These two layers are connected to each other along an edge extending around the material layers and form a central recess. The material layers form two separated inflatable spaces, an upper space and a lower, substantially U-shaped space.
  • the object of the present invention is to remedy the problems mentioned above and to provide a support device which forms an even and comfortable support for the person resting on the support device when it is inflated.
  • the support device initially defined which includes the features defined in the characterising part of claim 1.
  • the first support portion in the active state has a width which is substantially equally large along the whole extension of the first portion along the recess. In such a manner a fairly even support surface is ensured over the whole inflatable portion.
  • the second support portion may have a smallest width which is approximately equal to the width of the first support portion. Consequently, the two support portions will have the same height. It may however be advantageous to let the first inner support portion have a width and thus a height that is somewhat higher the height of the second outer support portion.
  • first support portion encloses a first part space of said space and that the second support portion encloses a second part space of said space, wherein the first part space communicates with the second part space.
  • the two support portions are the inflatable via a common opening in the inflatable portion. Because of that, a uniform distribution of the pressure and the lifting force form the two support portions is ensured.
  • the inflatable portion is divided into two part portions along a dividing line which substantially coincides with said axis.
  • Said material layers may also be connected to each other by means of a joint along at least a part of said dividing line.
  • the two part portions of the inflatable portion are separately inflatable independently from each other. In such a manner it is possible to lift a person resting on the inflatable portion more at one side than at the other side. The position of the person may thus be varied in an easy manner, which is essential in order to avoid so called bedsores.
  • the two part portions of the inflatable portion are substantially equally large.
  • said joint is formed by melting the material of the two material layers together.
  • the inflatable portion comprises at least one lateral projection, which is arranged to project beyond a lateral edge of the base member.
  • the lateral projection will thus extend outwardly from an outer lateral edge of the inflatable portion at the same time as the lateral projection forms a part of the inflatable portion.
  • the inflatable portion comprises two such lateral projections, which are provided at a respective one of said part portions.
  • said lateral projection may comprise at least one opening for the supply and evacuation of a gas for inflating the inflatable portion. The whole space of the inflatable portion is thus available via the opening, i.e. the first part space, the second part space and the part of the space located between the two material layers of the lateral projection.
  • each lateral projection may advantageously include such an opening, which permits the separate inflation of the two part portions.
  • the support device comprises two rods, which extend substantially in parallel with the longitudinal axis in the proximity of a respective outer lateral edge of the inflatable portion.
  • said rods extend beneath a respective lateral projection along said outer lateral edge.
  • the support device comprises a cover layer, which is arranged to extend between the inflatable portion and the base member, and to which the inflatable portion is connected.
  • a cover layer may for instance extend laterally outwardly so far that it may be arranged around the base member for attaching the support device to the base member.
  • the cover layer thus extends beneath the inflatable portion and the two lateral projections.
  • the cover layer is not connected to the lateral projections, which thus may project substantially straight outwardly whereas the cover layer extends downwardly around the base member.
  • the cover layer comprises two pockets for receiving a respective one of said rods. In such a way it is ensured that the inflatable portion obtains a favourable extension along the length of the base member.
  • said rods extend along substantially the whole length of the inflatable portion.
  • Fig 1 is a perspective view of the support device arranged on a bed
  • Fig 2 is a perspective view corresponding to Fig 1 , but with the support device in an inflated state.
  • Fig 3 is a view from above of the support device in Figs 1 and
  • Fig 4 is a cross-sectional view of the support device along the line IV-IV in Fig 3.
  • Fig 5 is an end view of the support device in Fig 2.
  • the support device is arranged on a base member 1 , which might be a mattress, a bunk, a bed or the like.
  • the support device disclosed is arranged on a base member in the form of a bed 1.
  • the support device comprises an inflatable portion 2, arranged to take an inflated, active state, see Fig 2, in order to lift a person (not disclosed) resting on the inflatable portion 2.
  • the inflatable portion 2 comprises a first edge portion 2a, which extends transversely across the bed 1 , and a second edge portion 2b, which also extends transversely across the bed 1 and is located at a distance from the first edge portion 2a. Furthermore, the inflatable portion 2 comprises a third outer edge portion 2c, which extends between a first end of the first edge portion 2a and a first end of the second edge portion 2b, and a forth outer edge portion 2d, which extends between a second end of the first edge portion 2a and a second end of the second edge portion 2b.
  • the two outer edge portions 2c, 2d extend substantially in parallel with a longitudinal axis x of the inflatable portion 2, see Fig 3.
  • the longitudinal axis x is intended to extend substantially in parallel with the longitudinal direction of the bed 1 .
  • the two outer edge portions 2c, 2d are also arranged to extend substantially in parallel with a respective lateral edge 3 of the bed 1. Furthermore, the two outer edge portions 2c, 2d are arranged to be located in the proximity of the respective lateral edge 3.
  • the inflatable portion 2 comprises two lateral projections 4, which are arranged to project outwardly over a respective lateral edge 3 and extend outwardly from the respective edge portion 2c, 2d.
  • Each lateral projection 4 comprises an inlet opening 5 and an outlet opening 6 for the supply of the inflating gas and for the evacuation thereof, respectively.
  • the two lateral projections 4 extend along a part of the respective edge portion 2c, 2d and are in the embodiment disclosed arranged substantially at the centre of the inflatable portion. Of course it is possible to arrange the lateral projections 4 any where along the respective edge portion 2c, 2d.
  • the lateral projections 4 form parts of the inflatable portion 2 and are thus also inflatable.
  • the inactive, substantially flat state which is disclosed in Fig 1
  • the lateral projections 4 will hang down over the lateral edges 3 of the bed 1. Because of that it is avoided that a person resting on the support device risks to lie on the unevenness formed in the area of the inlet opening 5 and the outlet opening 6.
  • the active, inflated state which is disclosed in Fig 2, the lateral projections 4 will extend substantially horizontally or straight outwardly from the inflatable portion 2.
  • the inflatable portion 2 comprises a recess 7 and support portions 8a, 8b, which are arranged around the recess 7 and to support a person resting on the support device.
  • the recess 7 extends inwardly from the second edge portion 2b along the longitudinal axis x and thus forms an end edge recess of the inflatable portion 2, wherein the inflatable portion 2 receives a U- like shape with two inflatable legs and one inflatable transverse portion.
  • the recess 7 is defined of a wall portion 9 of the inflatable portion 2.
  • a first of said support portions 8a substantially continuously continues in the wall portion 9.
  • the recess 7 is arranged to permit insertion of a bowl-shaped element 10 below the person resting on the inflatable portion 7 in the active, inflated state.
  • the bowl-shaped element 10 may be a bowl or a so-called basin of the type used within the medical service.
  • a so-called pull sheet (not disclosed) may be used, which extends over the support device and are tightened around the bed 1 .
  • the pull sheet In connection with the inflation of the inflatable portion 2 the pull sheet is released so that it permits the inflation of the portion 2 and is pressed down into the recess 7 for permitting the insertion and the positioning of the bowl 10 in the recess 7.
  • the bowl 10 comprises an upper edge portion forming a flange 11 which extends outwardly from the bowl 10.
  • the inflatable portion 2 may also comprise a support strip (not disclosed), which extends around the recess 7 and against which the flange 1 1 of the bowl 10 may be supported.
  • the support strip may be a part of the inflatable portion 2 and thus be inflatable. It is also possible to use a support strip in the form of a plastic strip, for instance.
  • the inflatable portion is formed of a first lower flexible material layer 14 and a second upper flexible material layer 15, which are connected to each other along a peripheral edge extending around the inflatable portion 2, wherein the two layers 14, 15 enclose a space 16', 16". Furthermore, the inflatable portion 2 is divided in two part portions 2' and 2" along a dividing line 17, which extends substantially centrally through the inflatable portion 2.

  • the two part portions 2', 2" which thus are substantially equally large, are separated from each other by means of a joint, extending along the dividing line 17 and dividing said space into two spaces 16' and 16".
  • the two spaces are completely separated from each other, but it is also possible to let these spaces communicate with each other via any passage.
  • the two part portions 2' 2" are in the embodiment disclosed inflatable via a respective inlet opening 5 and evacuable via a respective outlet opening 6 of a respective lateral projection 4.
  • the inflatable portion 2 is via a conduit 18 connected to a source for an inflating medium (not disclosed).
  • the conduit 18 is via a respective part conduit 18', 18" connected to the two inlet openings 5 and thus permits the inflating medium to flow from the source into the two spaces 16' and 16" of the inflatable portion 2.
