  • the present invention relates to a device for lifting and rising as well as for transport of persons or hospital patients completely or partly incapable of moving.
  • the present invention provides a lifting device of the character once described, comprising a rack preferably movable on wheels, at least four arms arranged essentially in a row and at some distance from each other, holding elements, in the form of slightly bent elongated plates with suitable rounded cross-sections, turnably journalled at one end of said arms and aimed to be able to be pushed in under the patient with the flat side against the patient and during a possible simultaneous turning movement, means provided at least at the outer arms for moving their respective holding elements further from and nearer to the adjacent holding elements.
  • the lifting device aims at imitating the natural grasp which one or several nurses may apply to a patient by pushing hands or arms under the patient into the free space formed between the patients body and the base at the neck part, under the sway in the back, under the seat and under the extremities.
  • the intention is to be able to lift and move a patient in laying position, to lift the patient into sitting position and to grasp and lift the patient in and out of e. g. a bathtube.
  • the aim is that the lifting equipment shall not hinder the access to the patients anal orifice.
  • FIG. 1 shows an endview of a device according to the present invention
  • FIG. 2 shows a side view of the same device
  • FIG. 3 shows a horizontal view of this device
  • FIG. 4 shows use of the device when lifting a patient out of a bathtub
  • F IG. 5 shows the patient in a laying position
  • FIGS. 6, 7 and 8 show the patient in different sitting positions
  • FIG. 9 shows a scheme over a hydraulic system for accomplishing the different movements.
  • FIGS. 10a and 10b shows schematically a joint embodied as a hydraulic rotator.
  • the device For the lifting of the patient the device has four convexly bent plates 1, 2, 3 and 4 formed so that, at a simultaneous turning from below upwards, they can be pushed under the patient (track a, b).
  • Two, the middle ones 1, 2 of them are meant to be placed under the patients seat part (0, FIG. 5) while one of the outer plates 4 is placed under the neck or shoulder part (d, FIG. 5) and the other of the outer plates 3 is placed under e.g. the patients hollow of the knee (e, FIG. 5).
  • the turning movement of the plates is brought about by rotators 5 affected by oilpressure and of a construction (FIG. 10) known as such.
  • Even other joint knots such as ones driven by electric motors or pneumatic ones can, of course, be thought of.
  • the middle plates 1, 2 are joined by means of fixed arms 6 to a beam 7 onto which also the other, outer plates 3, 4 are joined by means of flexible arms 8, 9, l0, 11.
  • the said beam 7 can be lifted and lowered under the effect of one or several pistons 12 (FIG. 9) in hydraulic cylinders 13.
  • the arm 8 is tumable (track h) in relation to arm 9 by means of a rotator 14 and arm 9 in its turn is turnable (track f) in relation to beam 7 by means of a rotator 15.
  • Arm 10 is pivoted (track k) in relation to arm 11 by means of a rotator 16 and arm 11 is in its turn tumable (track 3) in relation to beam 7 by means of a rotator 17.
  • the arm system 8, 9 and 10, 11 is tumable in one plane placed almost parallel with the vertical plane in the patients longitudinal direction so that the arms, when the rotator 15 is turned clockwise and the rotator l7 turned counter-clockwise (seen from the patients place) are able to take a position behind arms 6. I-Iereat the arm 9 is turned along track f and arm 11 moves along track g.
  • the arm 10 can also be displaceable sideways in a casing on beam 7, as shown in FIG. 3. Likewise, it can be thought an outer arm to be telescopic and provided with joints at its upper end.
  • the plates 1, 2, 3, 4 are fastened to interlinked rotators 5 on a pin 18 so that they may easily be set in a position comfortable for the patient by turning this pin around when the weight of the patients body affects the plates.
  • a plate 19 may be applied between the arms 6las support for the back of the patient at certain sitting positions (FIG. 2, 6).
  • control valves 20-27 FIG. 9, in a hydraulic system, in which the pressure is obtained e.g. from a hydraulic accumulator 28 charged by means of a hand or foot pump 29.
  • a hydraulic system in which the pressure is obtained e.g. from a hydraulic accumulator 28 charged by means of a hand or foot pump 29.
  • the pump 29 is driven by an electric motor and or the control valves 20-27 are controlled electro-magnetically. In the latter case controlling by the patient himself shall also be possible by using a system known as such with finger switches, blowing switches or suction and blowing switches.
  • the hydraulic system, the cylinders and the supporting beam 7 are suitably enclosed in casing 30 provided with wheels 31 in its lower part and further provided with wheelsupporting bars 33 directed outwards under the lifting plates 1-4. These bars may be turned, when required, in the horizontal plane inwards towards the centre (track 2) of the rack casing 30.
  • FIG. 10a shows in principle a cross section of a hydraulic rotator known in itself, which rotator can well be used in joint sections
  • FIG. 10b shows another section of the rotator when this has been fastened into two arms thus pivotally connected in relation to each others.
  • the invention provides a lifting device which is useful for handling patients but which can be applied to other objects inanimate as well as animate.
  • the lifting device of the invention has a portable base means (elements 30, 31, 32, 33, and beam 7) and a plurality of adjustable arm units supported by the base means and disposed to engage and thereby support the object to be lifted.
  • a portable base means (elements 30, 31, 32, 33, and beam 7)
  • a plurality of adjustable arm units supported by the base means and disposed to engage and thereby support the object to be lifted.
  • At least one, and in this particular embodiment two of the arm units are double-section arm units each having an inner arm section 9, 11, supported at one end from beam 7 of the base means for pivotal movement relative thereto about a first axis, as shown by the paths g and f.
  • To the inner arm sections 9, 11 are pivotally connected respective outer arm sections 8 and 10 and these each are moveable about a second axis as exemplified by the paths h and k.
  • the holding elements 1, 2, 3, and 4 extend in cantilevered relationship from their respective arm units and are pivotally connected thereto by the hydraulically powered rotator device 5.
  • At least one of the arm units in this case the two double-section arm units, have pivot connection means 14, 16 and 17 accommodating adjustment of the position of the holding element 3, 4, of that arm unit by independent horizontal and vertical movements.
  • fluid powered means including valves 20-27 and fluid operated rotary connectors 5, 14, 15, 16, and 17 that are operable to adjust the positions of the holding elements 1, 2, 3 and 4 as can be seen from FIG 9.
  • fluid powered means including the piston and cylinder combinations 12 and 13 associated with the base means and operable to adjust the position of the beam 7.
  • a lifting device which comprises a portable base means and a plurality of motorized adjustable arm units supported by said base means and disposed to engage and thereby support the object to be lifted, said arm units each having a holding element disposed for supportive contact with said object, at least one of said arm units having motorized pivot connection means moveable with the arm unit and accommodating adjustment of the position of the holding element of that arm unit by independent horizontal and vertical movements.
  • a lifting device according to claim 1 wherein said base means includes a moveable beam and said, arm.
