Description

A bedstead

The present invention relates to a bedstead, and more particularly to a bedstead for supporting a patient, optionally for prolonged period of time. The present invention finds utility in, for example, hospitals, rest homes, infirmaries, and similar facilities, by facilitating the care of chronically and/or acutely ill patients.

Background to the Invention Bedsteads, and particularly bedsteads for supporting a patient, are generally designed for significant patient comfort, given the extended and prolonged periods of time spent by the patient on the bedstead. Specifically in the case of chronically ill patients, conventional hospital, and other types of invalid, beds lack desirable features to improve the comfort of the patient. The problems associated with the treatment and movement of patients into and out of beds are well known. Particularly for severely incapacitated patients, the movement of the patients can cause strain and injury to both the patient and to attendants handling the patient. It is well known to those involved in bed patient care that, for acutely or chronically ill patients that are unable to move themselves, considerable time and effort on the part of attending nurses is required. It is an object of patient care to reduce and minimise the formation of, and/or to promote the alleviation of, bedsores for patients unable to move themselves into and out of bed, and/or within the bed itself. This requires that the patient be turned from side to side at least once every two hours, often requiring at least two nurses or attendants, depending on the size of the patient and his ability to cooperate in moving. For the totally incapacitated patient, this is invariably a difficult task under the best of conditions.

These situations require movement of the body of the incapacitated patient, who frequently is incapable of assisting, either in moving himself between positions on a bed, or readying himself to leave the bed.

Referring now to Figure 1 , there is shown a bedstead 10 according to a first aspect of the present invention. In a preferred embodiment, the bedstead 10 comprises a headboard 12; a footboard 14; and a platform 16 for supporting a patient. The platform 16 is arranged to be independently moveable relative to each of the headboard 12 and the footboard 14.

As illustrated in Figures 1 B and 1 C, the platform 16 is independently moveable relative to each of the headboard 12 and the footboard 14, such that, in use, the distance of the platform 16 relative to the ground is adjustable at or adjacent the headboard 12, and is independently adjustable at or adjacent the footboard 14. In a preferred embodiment, the platform 16 is independently slidably moveable relative to each of the headboard 12 and the footboard 14. As can be seen from Figure 1 B, the distance of the platform 16 relative to the ground at or adjacent the headboard 12 is adjustable independently to the distance of the platform 16 relative to the ground at or adjacent the footboard 14. Similarly, as can be seen from Figure 1 C, the distance of the platform 16 relative to the ground at or adjacent the footboard 14 is adjustable independently to the distance of the platform 16 relative to the ground at or adjacent the headboard 12. Figures 2A and 2B are a perspective view of a headboard 12 of the bedstead 10; although it is understood that the headboard 12 and the footboard 14 of the bedstead 10 comprise similar technical features; and, for the sake of convenience, a detailed description of the headboard 12 will be provided herein, which description also applies to the footboard 14. The headboard 12 comprises a generally rectangular frame 18. The frame 18 comprises, in use, upright members 20 and, in use, transverse members 22. In a preferred embodiment, the upright members are rigidly fixed. Optionally or additionally, the transverse members 22 are operable between a retracted position and an extended position. The transverse members 22 may be mounted to one another by a moveable coupling 24, optionally a reciprocally moveable coupling. In a preferred embodiment, the moveable coupling 24 comprises at least two scissor elements, each pair of scissor elements connected by a swivel axis 40 to permit displacement of the transverse members 22 between a retracted position and an extended position. Optionally, the headboard 12 further comprises a mount 26, which is, in use, secured to the moveable coupling 24. The mount 26 is slidably moveable relative to the headboard 12 by way of the moveable coupling 24. The moveable coupling 24 contained within the headboard 12 and the footboard 14 is used to stabilize, raise, lower, and rotate the platform 16. The mount 26 is mounted via a roller system and its rotation is driven by a drive system, such as a motor driven curved rack system, belt system, direct drive system, or other similar drive system, which can be selected by one skilled in the art.

As shown in Figure 7, in a preferred embodiment, the mount 26 is slidably mounted to the platform 16, such that the platform 16 can move reciprocally relative to the mount 26. Optionally, the mount 26 comprises at least one projection 68, which extends substantially perpendicular from the mount 26. In a given embodiment, the mount 26 comprises two projections 68, which of each extends substantially perpendicular from the mount 26. The platform 16 is arranged to receive each of the projections, which extend substantially perpendicular from the mount 26. Optionally, the platform 16 comprises an aperture 70 for receiving each projection 68. In a preferred embodiment, the platform 16 comprises two apertures 70, each aperture 70 for receiving a projection 68. Each aperture 70 is shaped and dimensioned to receive each projection 68 and to allow each projection 68 to move reciprocally therein. Accordingly, the platform 16 can freely move independently relative to each of the headboard 12 and the footboard 14.

In a given embodiment, each aperture 70 is shaped and dimensioned to receive each projection 68 and to allow each projection 68 to move reciprocally therein, and the reciprocal movement of each projection 68 can be actuated using actuating means. Optionally, the actuating means comprises a guide for guiding the reciprocal movement of each projection 68. Optionally, the actuating means comprises a moveable guide for guiding the reciprocal movement of each projection 68. Optionally, the moveable guide comprises a moveable aperture, shaped and dimensioned to receive each projection 68, optionally to co-operate with each projection 68. Optionally, the moveable guide, for example the moveable aperture, comprises a first elongate slot and a second elongate slot, wherein the first and second elongate slot together form a moveable guide, optionally a movable aperture. Further optionally, the moveable guide, for example the moveable aperture, comprises a first plate defining a first elongate slot and a second plate defining a second elongate slot, wherein the first and second plate are arranged such that the first and second elongate slots together form a moveable guide, optionally a movable aperture. Optionally, the first and second plates are moveable relative to one another. Further optionally, the first and second plates are slidably moveable relative to one another.

Optionally, the moveable guide, for example the moveable aperture, comprises a first plate defining a first elongate slot having a first orientation and a second plate defining a second elongate slot having a second orientation, wherein the first and second orientations are different orientations.

The first and second plates are arranged to be slidably moveable relative to one another, and such that at least a portion of the first elongate slot and at least a portion of the second elongate slot together form a moveable aperture. Optionally, the first elongate slot is oriented transversely relative to the second elongate slot, such that movement of the first plate relative to the second plate causes the at least a portion of the first elongate slot to move relative to the at least a portion of the second elongate slot, thereby forming a moveable aperture, which is shaped and dimensioned to receive each projection 68, optionally to co-operate with each projection 68. For example, each projection 68 can comprise a pin, which extends toward and passes through the moveable aperture. Accordingly, actuation of the movement of the first plate relative to the second plate causes the reciprocal movement of each projection 68. Alternatively, cessation of the movement of the first plate relative to the second plate can limit the reciprocal movement of each projection 68, thereby securing the headboard 12 and the footboard 14 to the platform 16, and providing a stable structure.

The headboard 12 may be arranged, for example telescopically arranged, to be extendable.

Accordingly, the extendable headboard 12 can be adjusted to any desirable height. In a preferred embodiment, the extendable headboard 12 can be adjusted such that, when the platform (optionally the bed base or mattress mounted to the platform) is moved above the, in use, top terminal edge of the headboard 12, the headboard 12 extends, such that the top terminal edge of the headboard 12 is in line with the platform (optionally the bed base or mattress mounted to the platform); thereby providing unrestricted access to the patient.

In a preferred embodiment, the platform 16 is mountable to the headboard 12. Optionally, the platform 16 is mountable to the mount 26 of the headboard 12. Further optionally, the platform 16 is hingedly mountable to the mount 26 of the headboard 12. Accordingly, the platform 16 can be slidably mountable to the headboard 12.

The linear motor drive to operate the variable height of the transverse members 22 of each of the headboard 12 and the footboard 14 can be spring assisted.

As can be seen in Figure 2A, in use, the headboard 12 defines a vertical axis 28. In a preferred embodiment, the platform 16 is mountable to the headboard and moveable along the vertical axis 28. The platform 16 can be slidably mountable to the headboard 12 and reciprocally moveable along the vertical axis 28. Accordingly, in use, the headboard 12 and the footboard 14 each define a vertical axis 28, and the platform 16 is slidably mountable to the headboard 12 and to the footboard 14, and is independently moveable along the vertical axis 28 each thereof.

Advantageously, an extended range of orientations can be achieved by the platform 16 being independently moveable along the vertical axis 28 defined by each of the headboard 12 and the footboard 14. The head or the feet of the patient can be elevated to increase circulation. The height of the platform 16 is achieved by the synchronous or independent raising and lowering of the headboard 12 and the footboard 14.

As can be seen in Figure 2B, in use, the platform can also be pivotably moveable relative to each of the headboard 12 and the footboard 14. In a preferred embodiment, the mount 26 of the headboard 12 is pivotable relative to the headboard 12. Accordingly, the mount 26 is arranged to be simultaneously slidably moveable relative to the headboard 12, and pivotably moveable relative to the headboard 12, by way of the moveable coupling 24. The platform 16 can then be pivotably mountable relative to the headboard 12. In a preferred embodiment, the platform 16 is pivotably moveable relative to each of the headboard 12 and the footboard 14 about a longitudinal axis of the platform 16. In such an embodiment, the headboard 12 and the footboard 14 define a longitudinal axis therebetween, about which the platform 16 is pivotably moveable. The platform 16 can be rotated up to 85° either way. The maximum angle of rotation can be determined by the weight of the patient.

Advantageously, the pivotable mounting of the platform 16 to each of the headboard 12 and the footboard 14 permits pivoting of the platform (and a patient thereon) about a longitudinal axis of the platform 16. Resultantly, the patient can be pivoted about the longitudinal axis without subjecting the patient to a pendulous or swinging motion, which can cause nausea in the patient. The pivot point for the rotation of the platform 16 is advantageously located approximately centre with the head of the patient as he is lying supine on the bed base 32 mattress, thereby allowing the patient to be pivoted through the centre line of the body and head, and thus preventing the patient from becoming disorientated or 'seasick'.

Resultantly, the platform 16 is independently slidably moveable, and is pivotably moveable, relative to each of the headboard 12 and the footboard 14. As can be seen in Figure 2C, the platform comprises a frame 30, which is generally rectangular in shape. The frame 30 is arranged to receive a bed base 32.

In a preferred embodiment, the bed base 32 is moveable relative to the platform 16, optionally slidably moveable relative to the platform 16. The bed base 32 can be slidably mountable to the platform 16.

In an alternative embodiment, the bedstead 10 comprises a headboard 12; a footboard 14; and a platform 16 for supporting a patient; wherein the platform 16 comprises at least two sections 34, each section 34 being arranged to be independently moveable relative to the platform 16.

The bed base 32 can comprise at least two sections 34, wherein each of the sections 34 is independently moveable relative to the platform 16. Each of the sections 34 can be independently slidably moveable relative to the platform 16, for example, each of the sections 34 can be independently slidably mountable to the platform 16. In a preferred embodiment, the frame 30 of the platform 16 comprises at least one rail 36 onto which the bed base 32 is slidably mountable, such that each of the sections 34 is independently reciprocally moveable relative to another section 34.

As shown in Figure 8, in a preferred embodiment, the bed base 32 can comprise two sections 34, wherein each of the sections 34 is independently moveable relative to the platform 16. Each of the sections 34 can be independently slidably moveable relative to the platform 16, for example, each of the sections 34 can be independently slidably mountable to the platform 16. In this preferred embodiment, each section 34 may be mounted to the platform 16 by a moveable coupling 38, optionally a reciprocally moveable coupling 38. In a preferred embodiment, the moveable coupling 38 comprises at least two scissor elements arranged to permit each of the sections 34 to be independently slidably moveable relative to the platform 16.

In a preferred embodiment, the bed base 32, optionally the mattress 32, is operable between a compressed state and an expanded state, as shown for example in Figure 5. Optionally, the mattress 32 is formed from a compressible material, such as polyurethane, optionally comprising additional chemicals to increase the viscosity and/or density of the compressible material.

Alternatively, the bed base 32, optionally the mattress 32, comprises corrugations (or recesses) 56, optionally repeating corrugations (or recesses) 56, oriented substantially perpendicular to the longitudinal axis of the mattress 32. Accordingly, the mattress 32 can be displaced between a compressed state and an expanded state, thereby following the position of the back of the patient, optionally when the section 34 is displaced between the reclined and inclined position. The displacement between the compressed state and an expanded state thereby preventing shearing and tearing of the skin of the patient in contact with the mattress 32. Moreover, the expansion of the mattress 32 when the sections 34 independently slidably move relative to on another prevents the patient from being forced toward the footboard 14 as the section is displaced between the reclined and inclined position. Optionally, the mattress 32 is secured to a first section 34 and to a second section 34, wherein each of the sections 34 is independently reciprocally moveable relative to the other section 34, as shown for example in Figure 8. Accordingly, the mattress 32, is operable between a compressed state and an expanded state as the sections 34 move independently reciprocally relative to one another. Optionally, the mattress 32 is longitudinally compressed and expanded, as shown for example in Figure 5. The operation between a compressed state and an expanded state as the sections 34 move independently reciprocally relative to one another prevents shear and adds to the overall comfort of the patient and the attendant.

It is understood that the bed base 32, optionally the mattress 32, is operable between a compressed state and an expanded state thereby reducing the shearing and tearing forces applied to the skin of the patient in contact with the bed base 32, optionally the mattress 32, and so finds utility in a number of applications not solely limited to a bedstead 10. Alternative embodiments of the present invention include, but are not limited to supports, seats, chairs, and bases; optionally reclining supports, reclining seats, reclining chairs, and reclining bases. As can be seen in Figure 3B, at least one of the sections 34 is adapted to reciprocally extend from the plane of the bed base 32. In a preferred embodiment, at least one of the sections 34 is operable between a retracted position and an extended position. The at least one section 34 may be mounted to the platform 16 by a moveable coupling 38, optionally a reciprocally moveable coupling 38. In a preferred embodiment, the moveable coupling 38 comprises at least two scissor elements, each pair of scissor elements connected by a swivel axis 40 to permit displacement of the section 34 between a retracted position and an extended position. In the retracted position, the at least one section is co- planar with an adjacent section 34. In the extended position, the at least one section 34 is in a different plane to an adjacent section 34.

Optionally or additionally, at least one of the sections 34 is operable between a reclined position and an inclined position. The at least one section 34 has a first end 42 and a second end 44. In the reclined position, the first end 42 and the second end 44 are in the same plane. In the inclined position, the first end 42 and the second end 44 are in different planes. Preferably, in the inclined position, the second end 44 and the adjacent sections are in the same plane; and the first end 42 is in different plane, optionally such that the section is angularly oriented relative to an adjacent section.

In a preferred embodiment, illustrated in Figures 3A and 3B, the bed base comprises four sections 34, wherein each of the sections 34 is independently slidably mountable to the platform 16, such that each of the sections 34 is independently reciprocally moveable relative to another section 34. As seen in Figure 3A, one of the sections 34 is adapted to pivot from the plane of the bed base 32, such that the section 34 is operable between a reclined position and an inclined position. It can be seen that, in the inclined position, the section 34 is angularly oriented relative to an adjacent section 34. In an embodiment, the section 34, which is operable between a reclined position and an inclined position, can comprise a section 34 for supporting the lumbar region of the patient. The section 34 for supporting the lumbar region of the patient can be recessed, or moveable to form a recess, such that the bed base 32 forms a recess to accommodate the lumbar region of the patient. Accordingly, in this specific embodiment, the five sections 34 of the bed base 32 respectively support each of the upper back, lower back, buttocks, thighs, and lower limbs of the patient.

The Trendelenburg position can be achieved by decreasing the distance of the platform 16 relative to the ground at or adjacent the headboard 12. The reverse-Trendelenburg position can be achieved by decreasing the distance of the platform 16 relative to the ground at or adjacent the footboard 14. In a preferred embodiment, in the inclined position, the section 34 is angularly oriented relative to an adjacent section 34, and, the distance of the platform 16 relative to the ground at or adjacent the headboard 12 is less than the distance of the platform 16 relative to the ground at or adjacent the footboard 14. Advantageously, the difference in the distance of the platform 16 relative to the ground causes the patient to be seated on the platform 16 in an economically beneficial position, wherein the head and torso of the patient are in-line, the back of the patient is supported fully with firm hold on the lumbosacral area, and the hips and thighs of the patient are supported. Accordingly, the centre of gravity of the patient is maintained in the correct position and prevents the patient from sliding down towards the footboard 14 of the bedstead 10.

The bed base 32 can be operable between a lying state and a resting state. In the lying state, each of the sections 34 of the bed base 32 is positioned in-side-by-side relationship with an adjacent section, optionally in the same plane. In the lying position, the bed base 32, for example a mattress, is level with the transverse sections 22, allowing unimpeded access to the patient. In the resting state, at least one of the sections 34, optionally an opposing terminal section, is extended from the plane of the bed base 32. Optionally, in the resting state, when the at least one section 34, optionally the opposing terminal section, is extended from the plane of the bed base 32, the at least one section 34, optionally the opposing terminal section, moves or is moved reciprocally toward the inclined opposing terminal section, such that the sections provide support to each of the hips, thighs and calves of the patient.

The bed base 32 can be a mattress.

The bedstead 10 is operable between the resting state and a patient-moving state. In the patient- moving state, at least two of the sections 34 are spaced apart, defining a space therebetween. Further optionally, in the patient-moving state, at least one of the sections 34 is extended from the plane of the bed base 32; and at least two of the sections 34 are spaced apart, defining a space therebetween. In a preferred embodiment, the bedstead 10 further comprises a support 46 for moving a patient between a recumbent position and an upright position. The support 46 can comprise a seat, and can be moveable relative to the bedstead 10. Further optionally, the support 46 is moveable relative to the platform 16 of the bedstead 10. In use, the support 46 is reciprocally moveable relative to the dorsal side of the patient, optionally, when the patient is in a lateral recumbent (lying on his side) position. In a preferred embodiment, the support 46 is angularly moveable toward the dorsal side of the patient, when the patient is in a lateral recumbent (lying on his side) position, such that the patient does not experience shearing of the support 46 against the skin.

In use, the support 46 is located adjacent, optionally in side-by-side relationship with, the dorsal side of the patient, optionally, when the patient is in a lateral recumbent (lying on his side) position. In the upright position, the support 46 is, in use, located adjacent, optionally in side-by-side relationship with, the dorsal side of the patient, the patient being in an upright position.

In a preferred embodiment, the bedstead 10 comprises a platform 16 for supporting a patient; a support 46; and an actuator 75 operable to move the support 46 between a recumbent position and an upright position. The actuator comprises a coupling 82 connecting the support 46 and the platform 16. The coupling 82 is arranged to move the support 46 such that the support 46 and the platform 16 are in a side-by-side relationship in the recumbent position, and the support 46 and the platform 16 are spaced apart in the upright position. In a preferred embodiment, the coupling 82 is arranged to effect and/or enable translational and pivotal movement of the support 46 relative to the platform 16. The translational movement and pivotal movement can be simultaneous or sequential translational and pivotal movement. The support 46 can be pivotably connected to the coupling 82 to enable the pivotal movement. Optionally, the coupling 82 comprises a restraining member 84 adapted to limit the pivotal movement of the support 46. In a preferred embodiment, the support 46, optionally the seat 46, is reversibly engagable with a seat base 48.

In a given embodiment, the bedstead 10 comprises a platform 16 for supporting a patient, the 5 platform 16 pivotable about at least one pivot axis 72, 74, such that the support 46 and the platform 16 are in a side-by-side relationship in the recumbent position, and the support and the platform are spaced apart in the upright position. In such an embodiment, it is appreciated that the platform 16 may comprise a frame 30, which is generally rectangular in shape, and arranged to receive a bed base 32. For the purposes of this embodiment, the platform 16 will be described as generally

10 rectangular in shape, and arranged to receive a bed base 32, wherein the bed base 32 is pivotable about at least one pivot axis 72, 74, such that the support 46 and the bed base 32 are in a side-by- side relationship in the recumbent position, and the support and the bed base 32 are spaced apart in the upright position; but it is understood that there are alternative embodiments, wherein the platform 16 is pivotable about at least one pivot axis 72, 74, such that the support 46 and the platform 16 are

15 in a side-by-side relationship in the recumbent position, and the support and the platform are spaced apart in the upright position.

In the recumbent position, the support 46 is generally oriented substantially perpendicular to the support 46 in the upright position. In use, the support 46 is oriented on its side and adjacent a patient on his side in the recumbent position; and the support 46 is oriented on its base and adjacent a seated patient in the upright position. The bed base 32 is pivotable about first 74 and second 72 pivot axes, the first 74 and second 72 pivot axes being different, spaced apart pivot axes. Each pivot axis 72, 74 comprises a hinge, for example a pivot axle rotatable within a pivot aperture.

25 As shown in Figure 9 for example, the bed base 32 can be pivotably mountable to the bedstead 10.

In a preferred embodiment, the bed base 32 can be pivotably mountable to a section 34 of the bed base 32 by a scissor jack mechanism 75. The scissor jack mechanism 75 can comprise base ends 76, 78 connected by at least two moveable arms 80, 82; and arranged such that each of the base ends 76, 78 are reciprocally moveable relative to one another. Preferably, the scissor jack

30 mechanism 75 comprises base ends 76, 78 connected by at least two, for example, pivotable arms 80, 82; and arranged such that each of the base ends 76, 78 is reciprocally moveable relative to the other. Optionally, the scissor jack mechanism 75 comprises base ends 76, 78 connected by at least two, for example, hinged arms 80, 82; and arranged such that each of the base ends 76, 78 is reciprocally moveable relative to the other. Preferably, the scissor jack mechanism 75 comprises first

35 76 and second 78 base ends, connected by first 80 and second 82 hinged arms; and arranged such that the first base end 76 is reciprocally moveable relative to the second base end 78.

In an embodiment, the actuator, for example the scissor jack mechanism comprises first 74 and second 72 pivot axes about which the bed base 32 can pivot, the first 74 and second 72 pivot axes

40 being different, spaced apart pivot axes. Optionally or additionally, the first base end 76 is slidably mountable to the bed base 32, such that the first base end 76 is slidably moveable relative to the bed base 32.

Optionally or additionally, the actuator 75 comprises first 74 and second 72 pivot axes. Optionally, the actuator 75 comprises first 74 and second 72 pivot axes, the first 74 and second 72 pivot axes being different, spaced apart pivot axes. Optionally, the actuator 75 comprises first 74 and second 72 pivot axes, the first 74 and second 72 pivot axes being different, spaced apart pivot axes, each mountable to the bedstead 10. Each pivot axis 72, 74 can comprise a hinge, for example a pivot axle rotatable within a pivot aperture, about which the bed base 32 can pivot.

Optionally, the support 46 is mountable to at least one of the moveable arms 80, 82 of the scissor jack mechanism 75; optionally pivotably mountable to at least one of the moveable arms 80, 82 of the scissor jack mechanism 75. In a given embodiment, an appendage support 50 for supporting the legs or lower limbs of the patient when the patient is in a lateral recumbent (lying on his side) position is mountable to at least one of the moveable arms 80, 82 of the scissor jack mechanism 75; optionally pivotably mountable to at least one of the moveable arms 80, 82 of the scissor jack mechanism 75. In such an embodiment, advantageously, the legs or lower limbs of the patient can be supported by the appendage support 50 during movement of the patient between a recumbent position and an upright position.

In the recumbent position, the base ends 76, 78 are spaced apart, such that the moveable arms 80, 82 of the scissor jack mechanism 75 are generally adjacent, whereby the support 46 and the bed base 32, are in a side-by-side relationship. Rotation about the first pivot axis 74 causes the bed base 32, optionally the section 34 of the bed base 32, to move from the reclined position toward the inclined position. Following movement of the section 34 of the bed base 32 to the inclined position, rotation about the first pivot axis 74 is impeded, and rotation about the second pivot axis 72 is permitted. Rotation about the second pivot axis 72 causes the bed base 32, optionally the section 34 of the bed base 32, to move from the recumbent position toward the upright position. In operation to the upright position, the first base end 76 is brought into closer proximity to the second base end 78, such that the moveable arms 80, 82 of the scissor jack mechanism 75 are generally displaced away from each other, facilitating translational movement of the support 46, whereby the support 46 and the bed base 32, are spaced apart in the upright position. The support 46 can be pivoted about the coupling 82 to facilitate pivotal movement to the upright position. However, it is understood that the support 46 can be spaced apart from the section 34, but remains connected to the section 34.

Also disclosed is a method for moving a patient between a recumbent position and an upright position using the bedstead 10. The method generally comprises the steps of displacing the bedstead 10 between the resting state and the patient-moving state; moving the support 46, optionally the seat 46, relative to the bedstead, optionally relative to the patient; and actuating the support 46, optionally the seat 46, between the recumbent position and the upright position.

As previously described, in use, prior to moving the patient between a recumbent position and an upright position, the patient is preferably in a lateral recumbent (lying on his side) position. This position can be achieved by turning the patient to a lateral recumbent or three-quarters prone position of the body. As can be seen in Figure 4B, turning the patient to a lateral recumbent or three- quarters prone position of the body can be achieved by, firstly, pivoting the platform 16 relative to the headboard 12 and the foot board 14, such that the platform 16 is laterally tilted. This lateral tilt facilitates turning the patient to a lateral recumbent or three-quarters prone position of the body. The platform 16 can further comprise a retractable appendage support 50 for supporting the legs or lower limbs of the patient when the patient is in a lateral recumbent (lying on his side) position. The retractable appendage support 50 for supporting the legs or lower limbs of the patient when the patient is in a lateral recumbent (lying on his side) position can be arranged to operate and retract automatically. The appendage support 50 can be adapted to operate independently of the sections 34 of the bed base 32, and is preferably mounted to the support 46 such that the appendage support 50 and the support 46 move in concert between a recumbent position and an upright position.

As shown in Figure 4C, the bedstead 10 is displaced between the lying state and the resting state. In the lying state, each of the sections 34 of the bed base 32 is positioned in-side-by-side relationship with an adjacent section 34 in the same plane. In the resting state, at least one of the sections 34, optionally a terminal section 34, is extended from the plane of the bed base 32. Extension of the section 34, optionally the terminal section 34, from the plane of the bed base 32 causes the adjacent section 34 to reciprocally slidably move with the extended section 34, such that, in the patient- moving state, at least two of the sections are spaced apart, defining a space 52 therebetween.

The support 46, optionally the seat 46, can be stored in a cabinet adjacent the bedstead 10. During the moving step, the support 46, optionally the seat 46, is moved relative to the platform 16 of the bedstead 10. Preferably, support 46 is moved relative to the dorsal side of the patient, such that the support 46 located adjacent, optionally in side-by-side relationship with, the dorsal side of the patient.

In a preferred embodiment, the support 46, optionally the seat 46 is moved relative to the dorsal side of the patient, such that the central axis of the support 46 is coplanar with the saggital plane of the patient. The support 46, optionally the seat 46, may be moved such that the bed base-engaging side edge of the support 46, optionally the seat 46, is, in use, recessed relative to the, in use, upper surface of the bed base 48, for example the mattress 32. Optionally, the bed base-engaging side edge of the support 46, optionally the seat 46, is, in use, located within a recess of the bed base 32, for example the mattress 32. Optionally, the recess is the space defined between a pair of sections 34 of the bed base 32. Accordingly, the saggital plane of the patient is coplanar with the central axis of the support 46, optionally the seat 46. As can be seen from Figure 4D, the actuating step comprises the bedstead 10 receiving, optionally reversibly receiving, the support 46, within the space 52 defined by the at least two spaced apart sections 34. The actuating step can also comprise the at least one section 34 engaging, optionally reversibly engaging, the support 46. In a preferred embodiment, the actuating step comprises displacing the at least one section 34 between the reclined position and the inclined position when the at least one section 34 is engaging the support 46, optionally by pivoting the platform 16 about the first pivot axis 74.

As shown in Figure 4E, the actuating step comprises pivotably moving the platform 16 relative to the bedstead 10. The support 46 can be pivotably moved when engaged to the section 34, which is displaced between a reclined position and an inclined position. In a preferred embodiment, the section 34 is operable between a reclined position and an inclined position about a first pivot axis 74, for example a hinge. As the section 34 is displaced between a reclined position and an inclined position, the section 34 moves reciprocally along the longitudinal axis of the platform 16, thereby sufficiently increasing the space 52 defined by the at least two spaced apart sections 34 to receive the support 46.

Rotation about the first pivot axis 74 is limited and effects rotation of the platform 16 about the second pivot axis 72. The first pivot axis 74, about which the platform 16, optionally the section 34, is operable between a reclined position and an inclined position; and the second pivot axis 72 can be the same or different pivot axes. Preferably, the first 74 and second 72 pivot axes are different pivot axes, whereby rotation of the platform 16 about the second pivot axis 72 effects the actuator 75, thereby facilitating translational movement of the support 46, whereby the support 46 and the platform 16, optionally the bed base 32, are spaced apart in the upright position. The support 46 can be pivoted about the coupling 82 to facilitate pivotal movement to the upright position.

The support 46, optionally the seat, can be engaged with a seat base 48. The seat base 48 can comprise wheels, such that the seat base 48 is mobile, thereby facilitating movement of the patient from the bedstead to another location. Optionally, the seat base 48 comprises a coupling to receive the support 46. The coupling may be, for example, pins, which extend, in use, upwardly, to receive the support 46 in the upright position. In a given embodiment, when the support 46 is received at the seat base 48, optionally received at the coupling, for example the upwardly extending pins, of the seat base 48; the support 46 is disengaged from the actuator 75. The bedstead 10, optionally the platform 16, and the seat base 48 may comprise at least one complimentary guide to facilitate alignment of the coupling to receive the support 46. The guide may comprise complimentary elements, which are shaped and dimensioned to reversibly engage in order to facilitate alignment of the coupling to receive the support 46.

In a preferred embodiment, the bedstead 10 further comprises a commode (not shown), which is moveable relative to the bedstead 10. Preferably, the commode is located at the platform 16, and can be located at the space 52 defined by the at least two spaced apart sections 34. Accordingly, in the patient-moving position, the commode is located at the support 46.

The bedstead 10 further comprises means for adjusting the height of the bedstead (not shown), for example, at least one adjustable foot, optionally a plurality of adjustable feet located, in use, at the ground-engaging face of the bedstead. Optionally, each adjustable foot which is correctly positioned and levelled prior to the headboard 12 and the footboard 14 being fixed thereto. Each adjustable foot can be securely fixed to the floor or on wheels. In a preferred embodiment, the bedstead 10 further comprises at least one castor 58. The castor 58 comprises a frame 60 and a wheel 62, wherein the wheel 62 is pivotably mounted to the frame 60, and wherein the point of rotation 64 is slidable relative to the frame 60. Optionally, the point of rotation 64 is reciprocally slidable relative to the frame 60. Optionally, the point of rotation 64 is reciprocally slidable relative to the, in use, central vertical axis of the frame 60. Further optionally, the point of rotation 64 is reciprocally slidable substantially perpendicular to the, in use, central vertical axis of the frame 60. The frame 60 can comprise an elongate slot 66, which is adapted to receive the point of rotation 64, such that the point of rotation 64 is reciprocally slidable substantially perpendicular to the, in use, central vertical axis of the frame 60. As shown in Figure 6, optionally, the frame 60 comprises an elongate slot 66, which is adapted to receive the point of rotation 64, such that the point of rotation 64 is reciprocally slidable substantially perpendicular to; and between opposing sides of; the, in use, central vertical axis of the frame 60 (see Figure 6, left hand side and right hand side).

operable between a lying state and a resting state; wherein, in the lying state, each of the sections of the bed base is positioned in-side-by-side relationship with an adjacent section; and, in the resting state, at least one of the sections is extended from the plane of the bed base.

21. A bedstead according to Claim 20, wherein the bedstead is operable between the resting state and a patient-moving state; wherein, in the patient-moving state, at least two of the sections are spaced apart, defining a space therebetween.

22. A method for moving a patient between a recumbent position and an upright position using a bedstead according to Claim 21 ; the method comprising the steps of:

(a) displacing the bedstead between the resting state and the patient-moving state;

(b) moving the support relative to the bedstead; and

(c) actuating the support between the recumbent position and the upright position.

23. A method according to Claim 22, wherein the method comprises the step of

displacing the bed base between the lying state and the resting state, prior to the displacing step.

24. A method according to Claim 22 or 23, wherein the actuating step comprises effecting and/or enabling translational and pivotal movement of the support relative to the platform. 25. A method according to any one of Claims 22-24, wherein the actuating step

comprises pivoting the platform about first and second pivot axes, wherein the first and second pivot axes are different, spaced apart pivot axes.

26. A method according to any one of Claims 22-25, wherein the actuating step further comprises the bedstead receiving the support within the space defined by the at least two spaced apart sections in the patient-moving state.

27. A method according to any one of Claims 24-26, wherein the actuating step further comprises disengaging the at least one section from the support, wherein the disengaging step comprises moving the support relative to the at least one section, such that the support and the at least one section are spaced apart.
