DETAILED DESCRIPTION

(8) Referring to FIG. 1 is shown the predominately horizontal surface (3) of a bed hereinafter the top. The illustration shows a hospital bed but it is to be understood that it could also represent a couch, a stretcher, an examination table, an operation table or any other surface that a person normally would sit on to before lying down onto the same. The patient's (1) starting position is sitting on the longer edge of the top of the surface (3) prior to lying down, facing upwards. The care giver (2) places the mobile patient support (4) adjacent one side of the patient (1), specifically on the same side of the patient (1) as the patient (1) is to lean in order to reach the final lying position on the top (3) of the bed. The contact surface of patient support (4) is preferably made of a material and structure that gives comfort to the patient (1), for example but not limited to, polypropylene, wood, polyurethane, combinations of these or any other suitable materials. The contact surface of the support (4) may be padded for added comfort and/or slightly curved.

(9) Referring to FIGS. 2 and 6, there is shown the apparatus prior to positioning by a patient. AS can be seen, the apparatus includes means for the care giver (2) to hold onto, in this embodiment being in the form of a handle (5) securely connected by an arm (6) to a coupling or pivot point (8) which allows rotation around an axis predominately perpendicular to the patient contact surface (9), allowing the handle (5) and arm (6) to be positioned predominately parallel to the edge (7) of the patient contact surface (9) or predominately perpendicular to the edge (7) of the patient contact surface (9) or at any angle in between. The arrangement with the rotatable coupling point (8), the arm (6) and the handle (5) provides a lever for the care giver (2) to aid in the task of tilting around axis A and respectively axis B as shown in FIG. 6.

(10) Referring to FIG. 6 the patient support (4) has a portion (C) shaped and sized to support the legs of a patient (1) and a portion (D) shaped and sized to support the upper body of the patient (1). Portion (D) is preferably generally parallel with portion (C) and most preferably substantially coplanar. The two portions (C) and (D) may be separated, if found suitable, by a lateral portion (E) providing lateral separation of portions (C) and (D). Portion (E) may be an extension of portion (C) or (D) or both, but could also be in the form of, for example but not limited to, a single or plurality of beams, a torsion spring with sufficient force to enable the function of the apparatus as described before.

(11) The patient support surface (9) may be flat or given a shape conforming or conformable to the shape of the side of a patient (1) which it is intended to support. Preferably, the patient support surface (9) is equivalent on both sides of the apparatus, giving it a longitudinal symmetrical appearance, illustrated by the two opposite facing patient supporting surfaces (9) in FIG. 6, thus to enable the apparatus to be used from either side of a patient (1), thereby to aid in getting into a bed from one side or the other.

(12) It is to be understood that the arrangement with the rotatable coupling point (8), the arm (6) and the handle (5) could be designed in other ways while still aiding the care giver (2) in the task of tilting around axis A and respectively axis B in the manner depicted in FIG. 6. One such configuration is shown in FIG. 7 where an edge profile (11) is rigidly connected via a connecting portion (10) with the patient contact surface (9), thus providing a lever for the care giver (2) to aid in the task of tilting around axis A and respectively axis B.

(13) Referring now to FIG. 3 the care giver (2) gently guides the patient (1) to lean with their upper body against the patient support surface (9) of the mobile patient support (4), causing it to tilt about axis A. The weight of the patient's (1) upper body onto the upper part of the patient support surface (9), together with assistance from the care giver (2) applying force on the handle (5), rotates the lower part of the patient support surface (9) about axis A and causes the patient's (1) legs to rise from a predominately vertical position towards a predominately horizontal position parallel to the surface (3) of the bed.

(14) Referring to FIG. 4 the care giver (2) then alters the position of the handle (5) from being predominately parallel to the edge (7) to being predominately perpendicular to the edge (7) in order to provide a lever aiding in in the task of rotating the patient support surface (9) about axis B so as to position the patient's (1) back against the surface (3) of the bed, along with the patient's (1) feet as illustrated in FIG. 5.

(15) Another embodiment of patient repositioning support is shown in FIGS. 8 to 12.

(16) Referring first to FIG. 8, the device includes a portion C1 shaped and sized to support the legs of the person or patient to be helped, wherein the portion C1 is substantially parallel to a portion D1 sized and shaped to support the upper body of the patient. The two portions C1 and D1 are preferably laterally separated to approximately fit the silhouette of an sitting person seen in the sagittal plane. In this regard, a lateral portion E1 which connects the portions C1 and D1 may be an extension of area C1 or D1 or both, but could also be in the form of, for example but not limited to, a single or plurality of beams, a torsional spring with sufficient rigidity to enable the function of the apparatus as described before.

(17) The patient support surface portions C1, D1 and E1 may be flat or have a shape to conforming or conformable to the patient's body. For example, the outmost part or side of the portion C1 near the patient's feet could be slightly inclined as shown in FIG. 10. Preferably the patient support portions C1, D1 and E1 have symmetrically opposing sides surfaces C2, D2 and E2 to be enable the device to be used from either side, thus enabling the single device to be used at a bed from one side or the other.

(18) As the device's contact surfaces C1/C2, D1/D2 and E1/E2 are designed to be in close contact to the patient's body, they are preferably made of a material and/or structure that gives comfort to the patient, for example but not limited to, polypropylene, wood, polyurethane, combinations of them or any other suitable materials characterized in being rigid enough to support the weight of the upper body and legs of the patient yet comfortable. They may have a soft covering.

(19) The device is intended to be rotated about the predominately horizontal axis A-A when bringing the patient from a lying to a sitting position or vice versa. Preferably the device includes gripping means which in this example is in from of one or several handles 103 located at or proximate the edge 105 of patient support portion D1/D2. The handle/s may be in the form of aperture/s in the support portion D1/D2, the edge 105 forming a handgrip that is suitable to grip around by the person helping the patient. Preferably, the handle 103 is located a distance from the axis A-A to form a lever to minimize the force needed to be applied by the caregiver to bring the patient from a lying position into a sitting position and in the same time being suitable for the range of motion of the caregiver.

(20) Another example of grip forms the edge 105 itself into a grip as seen in FIG. 9, where the edge 105 has an enlarged head 203 facilitating grip of the fingers of the caregiver to the device. The described examples are not limiting, several other ways of providing suitable grips may be realized by the skilled person, for example but not limited to, ropes and or webbing attached to the device, spherical formed extensions from the portion D1/D2, etc.

(21) To bring the device in rotation around the axis A-A, yet another point of grip 21 is preferably provided. The grip point 21 is preferably located spaced from the first handle/s 103 in order for the caregiver to be able to use both hands to add force contributing to the rotational movement and having a distance from the axis A-A to form a lever arm 23 to minimize the force needed to be applied by the caregiver to bring the patient from a lying position into a sitting position and in the same time being suitable for the range of motion of the caregiver. Preferably, the grip point 21 is located somewhere along a strut extending from the portion E1/E2 and not parallel to portion E1/E2. To provide a grip point 21 having a suitable distance from the axis A-A to suit different caregivers statute or different patient weights, the strut may be telescopic or provided with a multitude of grip points 21. Along the strut and preferably between the grip point 21 and the portions C1, E1 there is preferably provided a place or handle 20 for the patient to hold onto. Preferably the handle 20 is formed to accommodate at least one of the patient's hands, thereby enabling the patient to hold onto the device.

(22) To enable a single device to be used at a bed from one side or the other, the lever arm 23 preferably has two mirror inverted positions about a plane parallel to the portions C1, D1 and E1, illustrated by the first position P1 and the second mirror inverted position P2. The lever arm 23 is rotatably or flexibly attached to the device by a joint 22 allowing it to move between the two positions P1 and P2, with reference to a plane perpendicular to the axis A-A. The movement may take a path parallel to this plane or a path perpendicular to this, or any other path in between the two. Preferably, the pivotable or flexible joint 22 may transform into a rigid joint when desired or have two end positions characterized by the lever arm 23 being supported by said end position to work as a lever when applying force to the engagement point 21 to bring the device in rotation around axis A-A. In one of several possible embodiments, the joint 22 may be adjusted from a rotatable or flexible configuration to a rigid configuration by actuation of a locking pin on lever arm 23, passing into a corresponding recess in joint 22. In another embodiment the flexible joint 22 may be adjusted from a rotatable or flexible configuration to a rigid configuration by application of a force on the lever arm 23 exceeding a holding force in the joint 22, the holding force in joint 22 resulting from, for example friction, a spring loaded ratchet mechanism or similar device. The proposed embodiments of the joint 22 just serve as examples and several other ways of providing suitable solutions will be apparent to the skilled person having regard to the teachings herein.

(23) When a patient is to be brought in rotation around the transverse plane, that is to be rotated when sitting or lying near the edge of the longer side of the supporting surface of a bed towards the middle of the bed, the device is able to rotate around the predominately horizontal axis B-B. To facilitate this, the device preferably also includes gripping means in from of one or several handles 101, 102 about the edge 104 of patient support portion C1/C2. The handle/s may be in the form of aperture/s in the support portion C1/C2 in that the edge 104 forms a shape that is suitable to grip around by the caregivers. Preferably, the handle/s 101, 102 are located a distance from the axis B-B to form a lever to minimize the force needed to be applied by the caregiver to rotate the patient about the transverse plane.

(24) The edge or edges 106 of the device are designed to cooperate with the support surface of the mating equipment, in this example the mattress of a bed, without damage to the surface. In one embodiment, the edge or edges 106 may be made of a flexible material, for example but not limited to, polyurethane, neoprene or hollow formed polypropylene. In another embodiment the edge or edges 106 may be predominately stiff and given a rounded shape. The proposed embodiments of the edge or edges 106 just serve as examples, as several other ways of providing suitable solutions will be apparent to the skilled person having regard to the teachings herein.

(25) Referring now to FIG. 10, the device is shown aiding a person, the patient 1, from a lying position to a sitting position. The patient's body is in contact with the device in that the upper body resting on the device portion D1, the legs rest on portion C1 and the patient's pelvis rests on portion E1. When lying down the portion D1 and the patient's upper body are supported by the predominately horizontal surface 3 of the bed. The illustration shows a hospital bed but it is to be understood that it could also represent a couch, a stretcher, an examination table, an operation table or any other surface that a person normally would rest upon. The patient's legs are supported by the device portion C1, both being outside the horizontal support surface 3 ready to raise the patient and would typically also be the case when the patient is being moved from a sitting position to a reclining position. The portion E1 is stiff enough to keep the patient's 1 legs and upper body substantially parallel in the sagittal plane and the device will not introduce any unwanted twisting on the patient's body. For the patient 1 to feel safe and secure the patient 1 can hold onto the handle 20, which is at least rigid in the direction towards and away from the patient 1 when the patient 1 is in contact with the surfaces C1, D1 and E1 or C2, D2 and E2.

(26) To bring the patient 1 from the lying position to a sitting position the device is rotated around the axis A-A. Since the upper body of the patient in most cases is heavier than the legs, an assistive force is applied to rotate the device and patient 1 upwardly. The device will function as a see-saw rotating around the portion E1/2 and the pelvis of the patient 1, both supported by the surface 3, with the legs of the patient 1 contributing with force F1. The caregiver 2 will contribute a force F2 to bring the device and the patient up to a sitting position. The caregiver 2 can apply the force F2 at a single position or at multiple positions, where the force F2 will be divided into multiple lower forces. The force F2 will be inversely proportional to the distance to the axis A-A. For this purpose, preferably the caregiver 2 uses the grip point 21 which is rigidly connected to portion E1/2 and further uses the handle 103 which is spaced from the first grip point 21 and still provides a long enough lever relative to the axis A-A and at the same time provides a convenient grip for operation. The structure enables the caregiver 2 to steer the device manually while remaining in close contact with the patient 1, thereby being able to observe and attend to the needs of the patient 1 and regulate the speed of operation. Another way to apply the force F2 can be realized with beds that have articulated support surfaces 3, in that the backrest raise function may be activated to bring the device in rotation around axis A-A. In such an event, the caregiver 30 can aid in the rotation of the device by holding on to it via any of the provided support points, for example 21 and/or 103, giving it stability and being ready to add needed force and range of rotation motion as the articulated support surfaces 3 of the backrest will not necessarily have the range of motion needed for a complete transfer to a sitting position of the patient 1.

(27) When the device have been rotated, typically a quarter of a turn around the axis A-A, by the weight of the patient's legs and the aid from the caregiver and/or the aid of the articulated frame of the bed, the patient 1 will come to a sitting position on the edge of the support surface 3. In this position the caregiver 2 may effortlessly remove the device after ensuring the patient 1 has released their optional grip on the handle 20. Once the device have been removed from contact with the patient 1 and is no longer in close proximity to the bed, there will no longer be any additional device at the bed hindering integration with other activities or medical equipment.

(28) The procedure to go from a sitting position to a lying position is the reverse of the above described procedure.

(29) Referring to FIG. 11 the device can be used for displacing a patient 1 from a lying position near the longer edge of the support surface 3 into a more central position of the support surface 3 and onto their back while maintaining her legs and upper body parallel in the sagittal plane. By tilting the device around the axis B-B away from the caregiver 2 the patient 1 rolls over onto their by being pushed by the portions C1, D1 and E1. Preferably, the caregiver 2 will hold onto the device in one or several positions, by example there may be a handle 102 for the left hand and a handle 101 for the right hand, while the patient 1 can hold onto the provided handle 20. As the caregiver 2 will typically manually steer the device in close contact with the patient 1, the care giver 2 is able to adjust the speed and force of movement to the needs of the patient 1 when performing the manoeuvre. When the patient 1 has been turned to their back and has released their grip of the handle 20, the caregiver 2 can remove the device. The support surface 3 and bed-frame are then free from the device, allowing it to be used as intended without interference by the device.

(30) Referring to FIG. 12 the device can also be used for displacing the patient 1 from a predominately central position of the support surface 3 lying onto their back onto their side near the longer edge of the support surface 3, ready to be transferred to a sitting position by aid of the device and the caregiver 2. To maintain the legs and upper body parallel in the sagittal plane the caregiver 2 places the device into close contact to the patient's 1 body and such that the patient's shoulder abuts surface D1, the hip abuts surface E1 and the knees abut surface C1, or C2, D2 and E2 depending on side of the bed. In order for the knees to abut surface C1 they may need to be raised up from the support surface 3. Preferably the caregiver 2 will aid the patient 1 in this manoeuvre by raising the patient's knees while at the same time guiding the patient's feet along the support surface 3 to minimize friction. The patient 1 may be told or guided by the caregiver 2 to hold onto the handle 20 with at least one hand. The device and the patient 1 are then tilted around the axis B-B towards the caregiver 2 with the caregiver 2 holding onto the patient 1, gently pressing the patient against the device. The caregiver 2 can at any moment, as the situation dictates, shift one or both of the patient's points of contact to another or any suitable point on the device, preferably any of the provided grips, for example grip 101 to guide the device and the patient. As that the caregiver 2 manually steers the device in close contact with the patient 1, the caregiver she is able to adjust the speed and force of the movement to the needs of the patient 1 when performing the manoeuvre. When the patient 1 and the device have rotated approximately a quarter of a turn around the axis B-B the patient 1 comes to a lying position partly supported by the device portions C1, D1 and E1 and partly by the support surface 3, ready to be brought into a sitting position as described in earlier sections.

(31) Another method of helping a patient to get to their feet is by using a see-saw device 312 as shown in FIGS. 13 and 14. The device can also be used in combination with a ceiling lift (not shown) as shown in FIG. 15.

(32) As seen in these Figures, the device (312) is placed in front of the patient 1 with a sling (313) to support the back. The lower end (314) is placed under the patient's legs and the patient 1 is asked to grip the handles (315) midway of the device. The carer 2 (FIG. 13) or the ceiling lift (FIG. 15) is then able to position the patient to lie down on the bed or vice versa. The patient 1 will rock or cradle between the lying and upright positions.

(33) All optional and preferred features and modifications of the described embodiments and dependent claims are usable in all aspects of the invention taught herein. Furthermore, the individual features of the dependent claims, as well as all optional and preferred features and modifications of the described embodiments are combinable and interchangeable with one another.
