Definitions

  • This invention concerns a bed of the kind (hereinafter termed of the kind referred to) comprising hingedly connected sections adjustable between a flat configuration and a generally chair-like configuration.
  • the present invention is based on the discovery that quite small adjustments in the configuration of a bed of the kind referred have the effect of significantly moving the positions of maximum pressure between an occupant of the bed and the bed mattress.
  • a bed comprising a plurality of hingedly connected sections, characterised by means automatically to adjust the configuration of the sections of the bed at periodic intervals.
  • the bed may comprise three sections, a back-rest section, a central section and a foot-rest section.
  • the configuration of the bed may be controlled by a microprocessor.
  • the configuration of the bed may adjust in accordance with a selected one of a number of predetermined programmes.
  • the configuration of the bed may adjust in accordance with an operator generated programme.
  • the bed may incorporate pressure sensors at critical parts of the body prone to pressure sores of an occupant of the bed, there being means for comparing sensed pressures and the durations thereof with reference data to determine when the occupant is at risk of developing a pressure sore and means for adjusting the configuration of the bed when such risk is determined to mitigate the risk.
  • Each pressure sensor may comprise an array of strain gauges carried by a mat-like support.
  • the mat-like support may be located on, within or below the mattress.
  • Motors may be provided for adjusting the configuration of the bed.
  • Figure 1 shows a side view of the bed
  • Figures 2-5 show possible different configurations for the sections of the bed.
  • the bed comprises a rectangular base frame 10 which mounts ground engaging castor wheels 1 1, at least two of which can be immobilised by a brake pedal 12 to prevent unwanted movement of the bed over the floor.
  • a sub-frame 14 connected with the base frame 10 by four (two on each side) bell-crank levers 15, whose centre pivots are connected to posts 16 extending upwardly from the base frame 10 and whose upper ends are pivotally connected at 17 to the sub-frame 14.
  • the lower end of the lever 15 at the head of the bed is connected with the lower end of that at the foot of the bed by a link 18 and linear motor 19.
  • a further linear motor 20 drives a link 21 pivotally connected between a post 22 extending upwardly from the base frame 10 and the link 18 to move the lower arms of the bell-crank levers 15 forwardly or backwardly in the direction of the arrows X to raise or lower the sub-frame 14 relative to the base frame 10.
  • the bed itself comprising three hingedly connected sections, a back-rest section 30, a central section 31 and a foot-rest section 32, all of which support a mattress 33 (or mattress sections connected together by slide fasteners).
  • the back-rest section 30 is pivotally connected with the sub-frame 14 at 34.
  • a bell-crank lever 35 has its centre pivotally connected with the sub-frame 14 at 34, and the distal end of its rear limb pivotally connected with the hinge 36 between the sections 30 and 31.
  • a further linear motor 40 is operable to move the forward limb of the lever 35 fore and aft to raise and lower the back-rest section 30. It should be noted that raising the section 30 causes a lowering of the hinge connection 36 between the sections 30 and 31 and vice versa. This has the effect of preventing or minimising sliding movement of an occupant of the bed longitudinally therealong.
  • the footrest section 32 is connected with the sub-frame 14 by a pair of links 50 (one on each side) pivotally connected between the sub-frame 14 and the hinged connection 51 between the sections 31 and 32.
  • a link 52 is pivotally connected to the section 32 at its upper end, and to the distal end of a forward limb of a bell crank lever 53 whose centre is pivotally connected at 17 to the distal end of the rearward limb of the lever 15 adjacent the foot of the bed.
  • a further linear motor 54 is pivotally connected with the lower limb of the bell crank lever 53 to rotate the lever 53 about its centre to raise and lower the section 32 relative to the hinge 51.
  • Operation of the linear motor 19 causes rotation only of the rearward bell crank lever 15 adjacent the foot of the bed to cause the sub-frame 14 to pivot about the connection 17 between the sub-frame 14 and lever 15 adjacent the head of the bed to effect Trendenelberg movements of the bed.
  • Figures 2-5 show a number of possible different configurations for the sections of the bed.
  • the bed is provided with a control panel 60 incorporating a microprocessor capable of performing various functions.
  • one of a number of pre-selected programmes can be selected whereby the configuration of the bed will automatically adjust at pre-determined intervals in accordance with the programme parameters.
  • an operator may enter desired ranges of permitted angular movement for the back rest, the foot rest and Trendenelberg movement and a time interval desired between adjustments.
  • the control will then effect adjustments at the pre-determined intervals within the pre-determined parameters on a random basis.
  • control may automatically adjust the bed to prevent the incidence of pressure levels for periods longer than those which can be tolerated without the risk of pressure sores.
  • a sub-control panel 61 on an extensible lead is provided to enable an operator or indeed the patient to adjust the bed as desired at any time in any of its possible modes of movement.
  • the control panels include means to operate the motor 20 to raise and lower the entire bed structure relative to the base frame to position the bed at the most convenient height for re-making or transferring the patient to or from the bed.
