The present invention relates generally to patient handling and, more specifically, to methods and apparatus for lifting and transporting patients.
Persons with certain disabilities may have difficulty moving from a reclining position in bed to an upright sitting position. Often, such patients are manually lifted to a sitting position by a nurse or care giver. Unfortunately, manually lifting or otherwise moving a patient can hurt the patient by causing bruises, tearing skin, etc. Beds that can be converted into chair-like configurations that can assist patients in moving from a reclining position to a sitting position for the purpose of achieving a standing or walking position have been developed. However, alternative more economical devices are still needed.
According to some embodiments of the present invention, an apparatus for moving a patient between a reclining position on a bed and a generally upright sitting position includes a base, a lifting mechanism (e.g., a manual, electric, hydraulic, or pneumatic lifting mechanism) secured to the base, and an articulating patient support platform secured to the lifting mechanism. The patient support platform is movable via the lifting mechanism between raised and lowered generally horizontal positions. In some embodiments, a control system or unit with user controls is provided that operates the lifting mechanism to move the patient support platform between various raised and lowered positions.
The patient support platform includes first, second and third panels, each having a generally planar, rectangular configuration. The first panel is secured to the lifting mechanism and includes opposite first and second ends and the second panel is movably attached to the first panel first end and is upwardly pivotable from a substantially co-planar relationship with the first panel to a substantially orthogonal relationship with the first panel. The third panel is secured to the second panel in spaced-apart, substantially co-planar relationship therewith. The patient support platform is positionable on the bed such that a patient lying on the bed can be moved onto the patient support platform and positioned such that the patient's upper body is supported by the first and second panels and the patient's legs are supported by the third panel. The weight of the patient's legs on the third panel causes the third panel to move under the force of gravity and pivot the second panel upwardly such that the patient is moved to a generally upright sitting position.
In some embodiments, a fourth panel is movably attached to the first panel second end and is upwardly pivotable (e.g., manually or via an actuator) from a substantially co-planar relationship with the first panel to a substantially orthogonal relationship with the first panel. When the second and fourth panels are substantially orthogonal to the first panel, a patient in an upright sitting position on the first panel can be protected on both sides and prevented from falling to either side.
In some embodiments, the third panel is configured to be removable from the second panel and is configured to be removably secured to the fourth panel. This allows for the apparatus to be used on either side of a bed and/or when a patient is lying on a bed with his/her head at either end of the bed. When the third panel is removably secured to the fourth panel, the patient support platform is positionable on a bed such that a patient lying on the bed can be moved onto the patient support platform and positioned such that the patient's upper body is supported by the first and fourth panels and the patient's legs are supported by the third panel. The weight of the patient's legs on the third panel causes the third panel to move under the force of gravity and pivot the fourth panel upwardly such that the patient is moved to a generally upright sitting position.
In some embodiments, the apparatus includes first and second back support members for preventing a patient sitting in an upright position on the first panel from falling backwards. The first back support member is movably mounted to a side portion of the second panel and is movable between a stored position and an operative position in a substantially transverse relationship with the second panel. The second back support panel is movably mounted to a side portion of the fourth panel and is movable between a stored position and an operative position in a substantially transverse relationship with the fourth panel. The first and second back support members are each movable via a respective manual actuator attached to the second and fourth panels. However, in some embodiments, the first and second back support members may be movable via actuators.
In some embodiments, the first panel includes an opening formed therein that is configured to receive and/or support a bed pan or portable toilet device. As such, a patient in an upright sitting position may perform toilet functions via the bedpan or toilet device. In other embodiments, the apparatus may be rolled or otherwise moved into position above a toilet in a restroom to allow the patient sitting thereon to perform toilet functions.
The first, second and fourth panels may have various shapes and configurations. In some embodiments, the first panel has a length that is greater than a length of each of the second and fourth panels. In some embodiments, the second and fourth panels have substantially equal lengths.
The first, second, third and fourth panels may be formed of various materials including, but not limited to, one or more of the following: aluminum, stainless steel, carbon steel, mesh material, quilted material, and mattress ticking material.
In some embodiments, the base is a portable base comprising a plurality of wheels or casters that allow the apparatus to be moved about a room or facility.
According to other embodiments of the present invention, actuators (e.g., electric, hydraulic, or pneumatic actuators, etc.) are utilized to operate the second and fourth panels to move a patient to a generally upright sitting position. For example, in some embodiments, a first actuator is pivotably secured to a support member that extends (e.g., downwardly) from the first panel. The first actuator includes an extendable and retractable element that is connected to the second panel. When the element of the first actuator is fully retracted the second panel is substantially co-planar with the first panel, and when the element of the first actuator is fully extended the second panel is substantially orthogonal with the first panel. Thus, when a patient is positioned on the patient support platform such that the patient's upper body is supported by the first and second panels and the patient's legs are supported by the third panel, extension of the first actuator element causes the second panel to pivot upwardly such that the patient is moved to a generally upright sitting position.
Similarly, a second actuator is pivotably secured to a support member that extends (e.g., downwardly) from the first panel. The second actuator includes an extendable and retractable element that is connected to the fourth panel. When the element of the second actuator is fully retracted the fourth panel is substantially co-planar with the first panel, and when the element of the second actuator is fully extended the fourth panel is substantially orthogonal with the first panel. The fourth panel can be moved to be substantially orthogonal with the first panel at substantially the same time that a patient is being moved to an upright sitting position via the second panel, or subsequently thereafter.
When the third panel is removably secured to the fourth panel, and a patient is positioned on the support platform such that the patient's upper body is supported by the first and fourth panels and the patient's legs are supported by the third panel, the second actuator is configured to pivot the fourth panel upwardly such that the patient is moved to a generally upright sitting position.
A control system or unit with user controls is provided that operates the lifting mechanism to move the patient support platform between raised and lowered positions. The control system or unit also operates the first and second actuators to cause the second and fourth panels, respectively, to pivot upwardly.
According to embodiments of the present invention, a method of moving a patient between a reclining position on a bed and a generally upright sitting position via an apparatus is provided. The apparatus includes a patient support platform having a first panel comprising opposite first and second ends, a second panel movably attached to the first panel first end and upwardly pivotable from a substantially co-planar relationship with the first panel to a substantially orthogonal relationship with the first panel, and a third panel secured to the second panel in spaced-apart, substantially co-planar relationship therewith. The patient support platform is positioned in adjacent, overlying relationship with a bed upon which the patient is lying on. The patient is then moved onto the patient support platform such that the patient's upper body is supported by the first and second panels and the patient's legs are supported by the third panel. The second panel is then caused to pivot upwardly, thereby moving the patient to a generally upright sitting position.
In some embodiments, causing the second panel to pivot upwardly includes allowing the weight of the patient's legs on the third panel to move the third panel under the force of gravity and pivot the second panel upwardly. In other embodiments, causing the second panel to pivot upwardly comprises controlling an actuator to pivot the second panel upwardly.
In some embodiments, the patient support platform includes a fourth panel that is movably attached to the first panel second end and that is upwardly pivotable from a substantially co-planar relationship with the first panel to a substantially orthogonal relationship with the first panel. The method can further include moving the fourth panel to the substantially orthogonal relationship with the first panel at substantially the same time or subsequent to causing the second panel to pivot upwardly.
The first, second, third and fourth panels may be formed of various materials including, but not limited to, one or more of the following: aluminum, stainless steel, carbon steel, mesh material, quilted material, and mattress ticking material.
It is noted that aspects of the invention described with respect to one embodiment, may be incorporated in a different embodiment although not specifically described relative thereto. That is, all embodiments and/or features of any embodiment can be combined in any way and/or combination. These and other objects and/or aspects of the present invention are explained in detail in the specification set forth below.
The accompanying drawings, which form a part of the specification, illustrate embodiments of the present invention. The drawings and description together serve to fully explain the invention.
The present invention will now be described more fully hereinafter with reference to the accompanying figures, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like numbers refer to like elements throughout. In the figures, certain components or features may be exaggerated for clarity, and broken lines may illustrate optional features or elements unless specified otherwise. In addition, the sequence of operations (or steps) is not limited to the order presented in the figures and/or claims unless specifically indicated otherwise. Features described with respect to one figure or embodiment can be associated with another embodiment or figure although not specifically described or shown as such.
It will be understood that when a feature or element is referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items and may be abbreviated as “/”.
As used herein, phrases such as “between X and Y” and “between about X and Y” should be interpreted to include X and Y. As used herein, phrases such as “between about X and Y” mean “between about X and about Y.” As used herein, phrases such as “from about X to Y” mean “from about X to about Y.”
Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of a device in use or operation in addition to the orientation depicted in the figures.

The third panel 46 is secured to the second panel 44 in spaced-apart, substantially co-planar relationship therewith, as illustrated in
Referring back to
Similarly, another support member 60 extends down from the first panel 42 adjacent the second end 42b thereof. A second actuator 70 has an end portion 70a pivotably secured to the support member 60, for example via a rod or pin P. The second actuator 70 includes an extendable and retractable element 72 that is pivotably connected to a bracket B on the fourth panel 48 via a distal end portion 72a, thereof, for example via a rod or pin P. When the extendible element 72 of the second actuator 70 is fully retracted the fourth panel 48 is substantially co-planar with the first panel 42, as illustrated in
The portable apparatus 10 is movable relative to a bed such that the patient support platform 40 can be positioned above a patient support surface of the bed (e.g., a mattress) and then lowered via the lifting mechanism 30 onto the bed. The patient support platform 40 is configured to be positioned such that a patient can be easily rolled or otherwise moved onto the patient support platform 40 from the bed. Prior to being moved onto the patient support platform 40, the patient is typically rolled onto his/her side. The apparatus 10 is then moved closer to the patient such that the patient support platform 40 is touching or very close to the patient. The patient is then rolled or otherwise moved onto the patient support platform 40 such that the patient is in a somewhat fetal position with the patient's upper body supported by the first and second panels 42, 44 and the patient's legs supported by the third panel 46, as illustrated in
In some embodiments of the apparatus 10, an actuator is not utilized to move the second (or fourth) panel upwardly so as to move a patient to an upright, seated position. Rather, the weight of the legs of the patient under the force of gravity creates sufficient force downwardly on the third panel 46 so as to pivot the second panel 44 upwardly, thereby moving the patient to a seated position.
As shown in
The back support members 80, 82 may be formed of various materials including, but not limited to, aluminum, stainless steel, carbon steel, etc., as would be understood by one skilled in the art. The back support members 80, 82 may including padding (not illustrated) and may have various shapes and configurations. Embodiments of the present invention are not limited to the illustrated configuration of the back support members 80, 82, which are optional.
Each of the back support members 80, 82 may be manually operated via a respective handle 84 located on respective side portions 44c and 48c of the second and fourth panels 44, 48. Each handle 84 is connected to a respective back support member 80, 82 via an elongated rod 86 (

Various numbers and configurations of handles may be utilized without limitation.
The illustrated apparatus 10 includes an opening 90 in the first panel 42. A bed pan or portable toilet device 120 can be inserted within and supported by the opening 90 such that a patient in an upright sitting position may perform toilet functions. In some embodiments, padding (not shown) may be added around the opening 90 and/or around a bed pan or portable toilet device 120 inserted within the opening 90. Alternatively, or in addition, the opening 90 may be sized such that the apparatus 10 can be positioned and lowered over a toilet in a bathroom such that a patient sitting on the first panel can use the toilet.
In some embodiments, padding (not shown) may be provided around the toilet device 120. In other embodiments, a toilet device 120 is not inserted within the opening 90. Instead, a pad covers the opening 90 and is removed when access to the opening 90 is needed. As such, the apparatus 10 can be used to move a person to a seated position without necessarily requiring use of a toilet or a toilet device 120 inserted within the opening 90.
As discussed above, each lift column 32a, 32b can be operated by a linear actuator that is powered by an electric motor (not shown). A power supply 100 (e.g., one or more batteries, such as 12 volt 20 amp hour sealed batteries) is located on the base 20 and is configured to provide power to the electric motors for raising and lowering the lift columns 32a, 32b and is configured to provide power to the first and second actuators 70. In some embodiments, the power supply 100 includes a battery charger with a retractable power cord.
Control mechanisms 110, 112 can be provided on the base 20 and are configured to be operated by the foot of a user. Control mechanism 110 is configured to control operation of the lifting mechanism 30. In some embodiments, the control mechanism 110 is a synchronous control to ensure that the lift columns 32a, 32b are actuated synchronously. An exemplary synchronous control mechanism is the DCG24-2U-0280—LC2000/3000 control unit available from Thomson. However, control mechanisms from various manufacturers may be utilized. Embodiments of the present invention are not limited to any particular manufacturer of control mechanisms. Control mechanism 112 is configured to operate the first actuator 70 to cause the second panel 44 to pivot upwardly such that the patient is moved to a generally upright sitting position. Control mechanism 112 can also be utilized to operate the second actuator 70 to cause the fourth panel 48 to pivot upwardly to the substantially orthogonal relationship with the first panel 42. Exemplary control mechanisms suitable for use as control mechanism 112 are available from Thomson, as well as other manufacturers.
The illustrated apparatus 10 may include a seatbelt 130 or other restraining/safety device, as illustrated in
In some embodiments, and as illustrated in
In some embodiments, the apparatus 10 may be motorized for movement about a room or facility, and such movement may be controlled via a remote control device (e.g., a wired or wireless remote control device). In such embodiments, one or more of the wheels/casters 25 may be driven by one or more motors. In other embodiments, one or more additional wheels may be provided that are driven by one or more motors. In some embodiments, an application (“app”) operating on a smartphone or other computing device may be utilized as a remote control device for controlling operation and/or movement of the apparatus 10.
In some embodiments, the apparatus 10 may be configured to be attached directly to a bed or other furniture on which a patient may be reclining on. In such embodiments, the apparatus 10 may not need the base 20 or lifting mechanism 30. Rather, in some embodiments, the articulating patient support platform 40 would be attached directly to a bed or other furniture.
