Definitions

  • This invention relates to a disabled persons aid and in particular to a means and method for effecting a turning of a person whilst supported in a vertical or inclined position.
  • the problem to which this invention is directed relates to difficulties associated with turning disabled persons who may be confined to a bed.
  • Turning a patient can be achieved manually and conventionally requires more than one person. This may be either too expensive or extremely inconvenient as two or more people have to be employed or available on a regular basis to provide turning assistance. Furthermore, this may cause injury or strain to a person's back who assists in turning the patient.
  • an apparatus for turning a patient including: a first base having a first cushioning means adapted to support a patient; a second base having a second cushioning means adapted to support a patient; a locking means having a mechanical relationship with the first and second bases, the locking means being adapted to lock one of the cushioning means above the other cushioning means to sandwich the patient therebetween; and a rotation means adapted to provide a rotation of both bases such that support of a patient is transferred from one of the cushioning means to the other cushioning means.
  • both of the cushioning means are adapted to support the patient in a prone position.
  • the edges of the cushioning means protrude above the rest of the cushioning means so as to provide an enclosing effect when the patient is sandwiched between both cushioning means.
  • part of the cushioning means is adapted to be inflated.
  • At least one of the cushioning means has an aperture adapted to allow the patient to breath whilst sandwiched between both cushioning means.
  • an arrangement for effecting a turning of a patient confined to a bed which includes a first frame and a second frame, each of the frames being adapted to support a cushioning means, means to hold respective frames with supported cushioning means so that one is located above the other with a patient engageable space therebetween, and means at each end of the respective frames to interengage with a support means so as to allow the respective frames to rotate as a composite body with a patient encaptured therebetween.
  • a method of turning a patient including the steps of: supporting the patient upon a first cushioning means; sandwiching the patient between the first cushioning means and a second cushioning means; rotating the cushioning means so the support of the patient is transferred from the first cushioning means to the second cushioning means; and removing the first cushioning means so that the patient is no longer sandwiched between both cushioning means.
  • a method of turning a patient confined to a bed including the steps of: encapturing the patient between two cushioning means supported by respective frames one above the other, supporting from respective ends, the said frames so that the said frames are lifted together, rotating the frames as a composite body so that a first of the frames together with its attached cushioning means changes position from being below the patient to being above the patient, and the second frame with attached cushioning means changes its position from being above the patient to below the patient, and then lifting the uppermost frame together with its cushioning means away from the patient.
  • the frames are adapted to be lifted by lifting means to allow for the turning action.
  • the two cushioning means which can be appropriately shaped in difficult cases to conform to the body shape of a patient, have the purpose of providing safe rotation for weak patients or those with difficult limb distortions, body distortions or tender skin conditions.

These are pivotal I y secured to each other at 8 so as to allow relative positioning of the frames 2 and 4 from a position as shown in FIG. 1 to typicall a position as shown in Figure 4. Other position are available ( as shown in fo example in FIG. 2) noting that the lever arms 6 and 7 are located a first set at one end of the frames 2 and 4 and a second set at the other end.
  • the lever arms in each case are rigidly secured relative to the respective frames 2 or 4 so that they are not pivotally attached to their respective frames 2 or 4.
  • plate 11 which has a further spigot 12.
  • the plate 11 can have a number of hoies (not shown) so that the spigots 9 and 10 can be located in the plate so as to sandwich patients of differing physical sizes. Note other mechanisms are possible such as providing a slot in the plate 11 and replacing the spigot with a nut and bolt means.
  • a hoist with a lift frame What is not shown in the drawings is a hoist with a lift frame.
  • a hoist of a type that is generally standard within hospitals is used and the lift frame having two outermost supported loops are respectively engaged about the spigots 1 at one end and the other spigot at the opposite end. the whole of the assembly can be lifted relative to the bed base 1 such that a patient will be appropriately captured or sandwiched between the cushioning means faces.
  • the lifting by the hoist is then achieved through appropriate lifting mechanisms such as hydraulic lifting action and the turning of the patient is manually achieved by the nurse or other attendant simply manually pulling the composite assembly of the frames 2 and 4 and the other pieces around so that as shown in Figures 3 and 4.
  • the frame that was uppermost then becomes lowermost with its attached cushioning means and finally then as in Figure 4, the straps 15, the plate 11 can be disengaged and allow the frame to be swung away around the pivot 8.
  • Any appropriate support technique can be used which can include the arrangement of a permanently affixed support frame located at the respective ends of the frames .
  • a first frame can be swung across and joined with a removable pin, which replaces spigot 9. The uppermost frame is then released from capture and swung away leaving the patient in the turned condition on the lowermost frame.
  • the bed 16 includes two cushioning means 17 and 18 secured to two frames 19 and 20 respectively.
  • a patient would for example lie on cushioning means 17, the other cushioning means 18 is normally located underneath the cushioning means 17.
  • the patient is transferred from cushioning means 17 to cushioning means 18 with the cushioning means 17 and 18 swapping locations.
  • Two stands support the bed 16 in a stable upright manner with respect to the floor 22.
  • the stand 21 has a foot 23 upon the floor 22.
  • a box beam 24 provides structural rigidity to the bed 16.
  • a drive shaft 25 which is used to transfer drive from one stand to the other.
  • the gearbox 26 will be described further later.

  • Arm 30 supports frame 19 and arm 31 supports frame 20.
  • the arms 31 and 30 each have an extension 32 or 33 which are used to prevent rotation, by acting against plate 34, of the frames 19 and 20 through more than a ninety degree arc from the horizontal.
  • Locking means are provided to secure the arms 30 and 31 in a downward location, as illustrated, when not turning a patient.
  • Each arm has a rack one being shown at 35 which in conjunction with a pinion, one shown as 36, allows for linear movement of the frame 19 up the arm 30.
  • a sliding attachment is formed by the frame 19 to the arm 30 at 37.
  • the other frame 20 has a similar arrangement with arm 31 and the arrangement is also used at the other stand, not shown.

At each end of these drive shafts, one being 39, are the pinions which engage the racks of the arm, one being pinion 36. By rotation of a crank inserted at 40 into the worn drive gearbox 38 the frame 19 can be linearly moved along the arm 30.
  • the worm drive gearbox of frame 20 is connected to the other side of frame 20, when referring to FIG. 5, so that when the frame 20 is rotated to a vertical position both worm drive gearboxes are accessible from the same side of the bed. When in this position, the frame 20 can be lowered to the patient and so form a secure holding of the patient during the process of rotating the patient. If desired, the position of the frames 19 and 20 can be adjusted so that the axis of rotation is along the body of the patient. Note both frames can be operated in such a fashion so that in one configuration frame 19 is above frame 20 and in the other configuration frame 20 is above frame 19.

Abstract

Appareil permettant de retourner un invalide et comprenant une première base (49) possédant un premier matelas (50) destiné à supporter l'invalide, et une deuxième base (51) possédant un deuxième matelas (52) destiné à supporter l'invalide. Un moyen permettant d'intercaler l'invalide entre le premier et le deuxième matelas est prévu pour effectuer le retournement de l'invalide pris ainsi en sandwich de telle sorte que le transfert de l'invalide s'effectue d'un matelas sur l'autre. Selon un autre mode de réalisation, on décrit une méthode permettant de retourner un invalide et consistant à le soutenir sur un premier matelas puis à l'intercaler entre le premier (50) et le deuxième matelas (52). L'ensemble matelas-invalide est alors retourné de telle sorte que le transfert de l'invalide s'effectue du premier vers le deuxième matelas. Le premier matelas est alors retiré, libérant ainsi l'invalide.
