Patent Application
20220378637
The disclosure relates to portable patient lifting machines. Specifically, the disclosure relates to patient lifting machines used to move a patient from one position to another in many forms and iterations therewith on a hospital bed.
The following is not an admission that anything discussed below is prior art or part of the common general knowledge of persons skilled in the art.
U.S. Pat. No. 9,066,842 (Partridge) discloses a lift and move device to be strapped onto a hospital bed in order to lift and move an otherwise incapacitated patient. The lift and transfer and moving device includes a sling having a flat sheet configured with edges to accommodate a side laying person's back, torso, hips and upper legs, etc. The edges of the device allow a system wherein straps may be configured to reposition and secure the side laying person and, thus, to enable service personnel to reposition a bedridden person by tugging or pulling on the straps. These straps configure to both secure and rotate the patient so an attending caregiver may roll a laying patient from side-to-side and secure a side laying person on one side or angled side until time for rotation to the other side.
Partridge reference provides an example of a lifting and moving device that is separate and distinguishable from the hospital bed to which it is attached. Thus it may be capable of being detached and attached to a variety of beds.
It is lightweight, portable, attachable and detachable to a bed, capable of lifting, rolling and moving various body parts of a patient, U.S. Pat. No. 9,066,842 performs these functions using an intricate system of belts, straps, slings and buckles.
There exists no present apparatus or system therewith that performs these same functionalities which use a mechanical jack and/or jackscrew as a patient lifting and moving device. Additionally, there exists no present apparatus or system therewith that is compatible with an adapter configured to re-arrange the lift for horizontal use.
The hospital industry has been confronting an epidemic that plagues many of its staff: Tens of thousands of nursing employees suffering debilitating injuries every year, mainly from doing part of their everyday jobs—moving and lifting patients.
Nursing employees suffer more back and shoulder injuries than just about any other occupation. Workers who are relatively young have to stop working early in many cases. Often times they go home and experience pain in doing simple household endeavors such as lifting children, groceries, etc. These troubles stem from back injuries, arm injuries, and shoulder injuries suffered in the workplace.
Hospitals have reduced the number of injuries by buying special equipment to move patients and conduct intensive training to teach the staff how to use it. These efforts have in many instances dramatically reduced the instances of injury by nurses.
The need to turn from side-to-side and secure a person in positions confined to a bed with temporary or permanent loss of mobility is well known. Patient rotation from side-to-side is necessary for maintaining patient comfort, facilitating examination, and preventing bed sores from forming. Patients once moved might often need to be secured and placed in static positions wherein arms are raised, legs are elevated, backs are propped, etc. Manual lifting and turning of a bedridden patient is physically demanding for nurses, aides and others responsible for the care of the bedridden patient especially with average body weight in the industrialized world increasing annually. Such labor may result in injury to the back and other body parts of the person doing the lifting and/or turning of the patient. These injuries to nurses, aides and others result in time lost from the job, permanent disabilities, increased health care costs and litigation.
At present, the assemblies used to lift and move patients are very heavy, bulky and cumbersome. Elaborate sling systems mounted to overhead railings have been used to solve the problem of lifting and moving patients in hospitals. U.S. Pat. No. 4,117,561 relates to a wheel driven assembly outfitted with a base, and a boom out of which a sling mounts distally on a railing which extends laterally overhead. The machine can then be used to place a patient inside a sling hung by a chain or rope not unlike a child hanging from a swing set. U.S. Pat. No. 5,327,592 relates to a device which hangs stationary from a ceiling mounted swing which is powered to lift and lower by means of an electric hoist. The patient can be hoisted and lowered after being placed on a sling by one or more caregivers. Even more elaborate devices for lifting and moving patients include devices whose support structures extend a four cornered skeleton box-shape, wherein a mount can be placed overhead. Said mount can track in directions North, South, East, and West by means of elaborate wheeled assemblies. U.S. Pat. Nos. 5,337,908, and 5,511,256 by way of example describe separate incarnations of a hoist mechanism mounted to a frame which extends towards the four walls of a room. The frame itself is outfitted with various forms of rollers and track beams which allow for each respective hoist and sling to track across the room in various directions.
Moreover, assemblies for moving patients may be outfitted within the patient bed itself. Many patents provide examples of this concept in action. U.S. Pat. Nos. 7,568,240, 5,160,010, 5,173,975, 7,568,240, 4,409,695, 4,499,618, 5,105,486, 5,072,840, 5,613,255, 5,636,394, 5,687,437, 7,013,510, 7,237,286, 7,334,277, 7,441,291, 7,461,420, 8,006,332, 8,074,309, 8,104,120, are all examples of beds which are themselves devices which can perform various types of movement of the patient into a myriad of positions by means of moving any one or series of body parts vis-à-vis another body part or series of body parts.
More recently, mechanisms used to move and lift patients have become more portable. U.S. Pat. No. 6,430,761 B1 shows a device which can be wheeled into a room and has no overhead lift and carry sling. Instead it consists of a lifting column which can be lifted and lowered by means of a hand crank mechanism. A seat sling is hung from the lifting column and the patient him or herself or an attendant may place said patient on the seat sling and then move the patient on or off of a bed or wheelchair or car seat as needed. This device collapses into a portable instrument which can be moved, not unlike a piece of wheel-mounted luggage.
Another portable, highly specific patient moving device can be seen in the example of U.S. Pat. No. 8,997,276 B2. Here a boom is attached to a mast on a corner of a patient's bed. Said boom is optionally outfitted with a sling, which like the above-mentioned moving devices is capable of hoisting a patient up off of a hospital bed. The configuration of the present example allows for the patient to be rotated and consequently transferred by the boom along the vertical y-axis represented by the mast configuration.
Other mechanisms used in the industry have been proven effective but are highly specified in terms of the type of movement and/or transfer affect. For instance, 8,261,380 B2 describes a modified stretcher that is outfitted as a bed accessory. Said accessory can facilitate a prone to supine or supine to prone patient transfer. The accessory is placed adjacent to a stationary bed, and it is capable of providing a flat surface which can be tilted at any angle from 0° to 90°. This has the effect of assisting an attendant to turn a patient from supine to prone or vice versa.
Some more recent devices are mobile, multifunctional, and display modular components which may be used to lift and/or transfer patients. Modularity allows for the use of various types of moving mechanisms to be utilized to satisfy the nuances of a particular assisted movement: slings, chairs, straps, harnesses and/or transfer sheets may optionally be used. U.S. Pat. No. 8,336,133 B2 is an example of a mobile multifunctional patient transfer device wherein a lift cart is outfitted with a host of optional lift components. Once placed adjacent to a patient bed, said device may act in various capacities and be outfitted to fit a host of desired transfer motions based on the needs of the attendant. Lift components may include frontal bars, tabletops, bars, hoists, knee blocks and supports, detachable handles, safety cushion(s) and the like. Said components can assist an attendant in performing frontal transfers, lateral seated transfers, lateral bed transfers, and sit-to-stand transitions based on the needs of the attendant.
U.S. Pat. No. 5,323,498 A provides an example of an elaborate device with a series of boards capable of wedging themselves underneath a patient lying on his or her bed. The device may then tilt and/or lift the patient off of a bed so that the patient may then be placed back on the bed at a different position. Again, like many of the aforementioned mechanisms, the present device needs to be wheeled into a patient's room and subsequently placed adjacent to the bed. Similarly, a four wheeled device shown in U.S. Pat. No. 6,662,388 shows a mechanism placed adjacent to a patient's bed where an elaborate means for moving said patient is accomplished by means of sliding an object between a patient and the bed he or she is laying upon. In this instance, the object is a flat, flexible sheet. The device utilizes a lifting assembly, a base supporting said lifting assembly, a vertically adjustable shaft, a horizontal load-bearing boom-like member for attaching said horizontal load-bearing member and a generally flat, flexible sheet upon which the patient is supported.
Still others accomplish moving and/or lifting a bedridden patient by means of inflation-based technologies. U.S. Pat. No. 7,007,330 B2 is one such example. Here, the device comprises inflation bladders configured to be secured between the patient's body and the patient's bed. The bladders are inflated with pressurized fluid. The configurations of surrounding bladders and the choice of which bladders to inflate determine the direction of movement of the bedridden patient, body-part by body-part. Another, less complex example is seen in U.S. Pat. No. 4,005,498 A. Here the device is a singular inflatable pad having a control pocket formed thereon for receiving a hospital attendant's arm. The pad may be inserted underneath the patient with the control pocket and attendant's arm being positioned above the inflatable pad and in contact with the patient's body. Inflation accomplishes the goal of moving a desired part of the patient's body, such as his or her buttocks, lower back, upper back, upper leg, lower leg, knee(s), arm, head, neck and the like. Still another such example of an inflatable device can be found in U.S. Pat. No. 7,617,553 B1 wherein an inflatable device is used to specifically lift the rectal region of a bedridden patient.
There exists no ultra-portable, ultralight device for moving patients which utilizes jack and jackscrew-based foundational mechanical technologies. Likewise, there exists no ultra-portable, ultralight adapter device for re-arranging the orientation of devices utilizing jack and jackscrew-based foundational mechanical technologies.
Briefly described, in an example embodiment, the present apparatus and method to overcome the above-mentioned disadvantage, and meet the recognized need for a body lift, positioning, propping and securing device and methods of use comprising, in general, a configured cushion(s) or series of fitted cushions induced to partially fit in an angle adjustable mount or cradle which itself may be bolted to a modified mechanical screw-type jack configured to attach to a base plate which lays flat on the patient's bed. The mount or cradle may be comprised of carbon fiber, aluminum or similar ultra-light and strong substance known in the field. The internal cradle may be shaped like a rectangular five-sided box that accepts a foundational cushion with a rectangular bottom that hangs over the internal cradle. A plurality of cushion(s) may each be respectively dimensioned to accommodate a person's back, torso, shoulder, hips, legs, and feet wherein at least one curved cushion(s) adjoined to a cradle rest upon a specified and targeted patient body part. A nurse or any patient attendant may reposition and secure the laying person into a series of desired body positions using a system comprised of a modified mechanical jack and the adjoining cradle and interchangeable cushion(s). Service personnel may reposition a bedridden person by using the mechanical jack, adjoining cradle and cushion(s) to reposition, prop and secure the laying patient from a supine or prone laying position into a new position wherein one or more body parts are lifted, raised and secured by the device. The device once set, may prevent the patient from moving from side-to-side, rolling or otherwise shifting into a position not in keeping with the attendant's desires.
In an exemplary embodiment, a body lift and positioning device and methods of use, the apparatus including a base, a joint, for example, a radial adjustment head, a mechanical jack, an internal cradle and one or more cushion(s) dimensioned to conform and contour to a particular patient body part thereon. The method including the steps of providing a body lift and positioning apparatus, the apparatus having a base capable of moving, for example, repositioning, on a bed, a mechanical jack capable of being lifted and lowered by means of a rotational device, for example, a socket driver, and contoured cushion(s) configured to fit a particular body part of a person, for example, an immobile or obese patient.
In still a further exemplary embodiment of the invention, the cushion(s) is contoured to fit underneath a patient's back. In some embodiments of the invention a plurality of cushions may be fitted onto one another and configured to conform to a patient's torso for tilting sideways. In some scenarios, for the purposes of storage and transport the cushions may seat into each other making it possible to move many body parts yet still fit the cushions in a relatively small duffel bag. In some embodiments of the invention a plurality of cushions may be fitted into one another and configured to conform to the bottom of a patient's legs to aid in circulation by raising the legs above the heart. In yet another embodiment of the invention a cushion(s) may be fitted in order to facilitate propping a patient on their side to aid in changing bed pans.
In a method of assembly of an exemplary embodiment of the device, an attendant may attach the bottom of the mechanical screw-type jack to pegs resting on the top center of a large base plate at 90-degree angles. The jack may be attached to the base plate and the joint or radially adjustable accepter head may be attached to the end of the jack's lever arm via carriage bolts (if it wasn't left on by the last user and therefore already attached to the lift). Next, the cushion mount or cradle may serve as an internal skeleton to give a cushion strength and stability as well as to give the cushion a hard upper platform to be inserted into the lift and an angle may be selected for the cradle by way of the radial adjustment head using a ball lock pin. In some embodiments, the mount's upper platform may include slots or cavities configured to receive protrusions or columns extending from the cushion(s) to secure the cushion(s) to the cradle or mount. For example, the cushion or plurality of cushions may be fitted together and attached to the cushion cradle by way of columns at the bottom of the cushions that fit into the cradle for a snug fit. Last, an attendant may select the appropriate cushion(s) or plurality of cushions. The attendant or attendants may move the device across the bed and place it partially underneath and/or adjacent to the body part that the attendant wishes to lift and prop. The attendant or attendants may manually move the patient using a strap or sling or by means of their hands alone in order to place the lift under the patient. The movement, however, will be minimal in that lifting the body part may be necessary to the extent that said body part can be placed upon the lowest setting of the mechanical jack. Once the base, lifting unit, adjustable head, cradle and appropriate cushion(s) are assembled the attendant may place the appropriate patient body part or region into the appropriate cushion(s) (top portion of the assembled device) and then, using a rotational device, for example, a powered socket driver, lift the patient's body part to any desired height within the range of the jack's capabilities.
Accordingly, a feature of the medical lift and positioning device and methods of use is its ability to enable a single attendant to comfortably maneuver, reposition, roll, lift and/or prop a body part of a large bedridden patient with no other tool needed. In some embodiments, only an accompanying strap is needed to comfortably maneuver, reposition, roll, lift and/or prop a body part of a large bedridden patient. The device itself may be designed for such ease of maneuverability. Moreover, multiple devices may be used to lift and prop more than one patient body part at a time, for example, with a bench accessory that straddles the two lifts.

In any embodiment, any portion of the adapter may be made from any single or combination of sturdy materials, such as carbon fiber, polymer, resin, and plastic, Kevlar, forged metals, wood and the like.
In accordance with embodiments of the present invention, an adapter may be utilized to change the orientation of the lift device. In some examples, changing the orientation of the lift device may change the application of the device, for example, from being utilized to move a body part or person along a vertical axis (e.g., up and down), to being utilized to move a body part or person along a horizontal axis (e.g., side to side).
In some embodiments, an adapter may be configured as an intermediary component, connecting the lift to the base. For example, a portion of the adapter may be configured to connect or engage with, or hold the base of the lift, and another portion of the adapter may be configured to engage or connect with, or hold, at least a portion of the legs or bars of the lower support member.
In accordance with embodiments of the present invention, an adapter may comprise an adapter base and an adapter body.
In accordance with embodiments of the present invention, the adapter base may comprise a platform element configured as a thin plate comprising a bottom side and a top side, a lift base connector portion, and an adapter body connector portion.
In accordance with embodiments of the present invention, the bottom side of the adapter base may be substantially flat and may comprise one or more connection points, for example, one or more openings or sockets adapted to receive one or more pegs of the lift base, to support connection of the adapter base to the lift base. In accordance with embodiments of the present invention, the adapter base may be used alone or in conjunction with the lift base. For example, in some embodiments, the adapter base may be configured to mount on or otherwise couple or connect to the lift base, whereas in some embodiments, the adapter base may be a standalone component which may be configured to support the weight of the adapter component and/or the lift device connected thereto.
In accordance with embodiments of the present invention, the top side of the adapter base may comprise a lift base connector portion and one or more adapter connector portions, for example, a pair of adapter connector portions. In some examples, the base connector portion and the one or more adapter connector portions may protrude from a top side of the adapter base.
In some examples, the lift base connector portion may comprise one or more connector components, for example, four connector components which protrude from the adapter base, each connector component comprising a hollow opening configured to receive and/or retain the pegs of the lift base. In some examples, each connector component may be integrally formed with the platform element of the adapter base, or may be permanently or removably attached to the platform element, for example, by means of adhesives, screws, pins, and any other permanent or removable attachment means. In some examples, the openings or sockets of the adapter base bottom side may extend towards the adapter base lift base connector portion, for example to the one or more connector components which may protrude from the top side of the adapter base. In some examples, the adapter base may comprise a predetermined amount of sockets and/or connector components. For example, the adapter base may comprise sockets and/or connector components corresponding to the number of pegs in the lift base. In some examples, the sockets and/or connector components may be less than or may exceed the number of pegs in the lift base. In some examples, the connector components may be standalone components or may connected to (e.g., attached to or integrally formed with) one or more additional connector components, for example, to improve stability of the connection between the adapter base and the lift base. In some examples, the connector components may be generally cylindrical, however, in any embodiment, the connector components may be formed in any shape suitable to have a hollow opening and/or channel disposed therein for supporting connection to the lift base.
In accordance with embodiments of the present invention, the adapter connector portions may protrude from the top side of the adapter base. In some examples, the adapter connector portions may comprise one or more, for example, two, protruding connector elements, for example, sequentially layered according to size (e.g., larger to smaller). In some examples, the protruding connector elements may be substantially rectangular (e.g., rectangular prisms) and may have rounded corners. In scenarios with two protruding connector elements, the protruding connector elements may be arranged with, for example, a first protruding connector element protruding from the top surface of the adapter base, and a second, smaller protruding connector element, protruding from a top surface of the first protruding connector element. In some examples, a slot or groove may be formed between a first protruding connector element and a second protruding connector element and may be adapted to receive an end portion of an arm element. For example, a generally hollow arm element may comprise a thin-walled and substantially rectangular end portion (with optional rounded corners) which may be configured to correspond to, and fit within, the slot or groove formed between the first and second protruding connector elements to support securement of an arm element to a protruding connector portion (e.g., such a thin-walled substantially hollow end portion of the arm element may fit snugly within the slot or groove on the adapter connector portion to support securement of the arm element to the adapter base). In any embodiment, the protruding connector elements may be generally rectangular (e.g., rectangular prism) or may have any other suitable three-dimensional shape, including cylindrical, cube, hexagonal, ovular, spherical, or any other similarly suitable three-dimensional shape. In some embodiments, the protruding connector elements may comprise connector pins and/or receiving holes corresponding to receiving holes and/or connector pins disposed on the arm elements. For example, the protruding connector elements may comprise one or more, for example, two, receiving holes configured to support attachment of the adapter body to the protruding connector elements, for example, by corresponding in shape to and adapted to be received by corresponding connector pins disposed on the arm elements. In some scenarios, the receiving holes may be substantially hexagonal in shape, however, in any embodiment, the receiving holes may have any other similarly suitable shape, including circular, ovular, square, rectangular or any other shape. Moreover, for example, the protruding connector elements may comprise one or more connector pins configured to support attachment of the adapter body to the protruding connector elements, for example, by corresponding in shape to and adapted to be received by receiving holes disposed on the arm elements. In some examples, connector pins may comprise a substantially cylindrical body portion and a substantially rounded top portion and may protrude from and/or may be formed with or otherwise connected to the protruding connector elements. In any embodiment, the connector pins may be any similarly suitable shape, for example, rectangular, hexagonal, or square shapes. In preferred embodiments, the connector pins and receiving holes correspond to each other in shape.
In accordance with embodiments of the present invention, the adapter body may comprise one or more arm elements and one or more bridge elements. In some embodiments, the arm elements may be substantially rectangular elongated blocks. In any embodiment, the arm elements may be formed in any other similarly suitable shape, for example, a generally cylindrical, hexagonal, or any other geometrically suitable shape.
In accordance with embodiments of the present invention, the bridge element may comprise one or more lift fastening means. In some embodiments, the lift fastening means may be a clamp implement, a snap locking implement, a pressure fit implement, a magnet implement, or any combination of the foregoing. For example, the lift fastening means may comprise a pair of tensioned protruding portions forming a clamp. The lift fastening means may be configured to support connection of the adapter body to the lift device, for example, at the lower support member of the lift device. In some examples, the lift fastening means may be a clamp member or snap locking member adapted to receive, clamp or snap fasten a portion of the t-shaped component of the lift device to the bridge element of the adapter body.
In accordance with some examples, the adapter body may comprise a pair of arm elements operably connected to a bridge element. In some examples, the arm elements may be pivotally connected to the bridge element. For example, a top portion of each arm element may be pivotally connected to an end of the bridge element by means of a pivoting mechanism. In some examples, a pivoting mechanism may comprise a slot, or series of slots, in the arm elements and a pin configured to travel in the slot(s) formed in the arm elements.

In some scenarios, an attendant may select the appropriate cushion or plurality of cushions 50 for use. The attendant or attendants may reposition the device 100 across the support surface, for example, a bed, and place it partially underneath and/or adjacent to the body part that the attendant wishes to lift and prop. The attendant or attendants may then manually move the patient or patient body part using a strap or sling or by means of their hands alone. The movement required however, will be minimal since the body part may be placed upon the lowest setting of the lift 14. Once the base 11, lift 14, joint 35, mount 30 and appropriate cushion(s) 50 are assembled, the attendant may place the appropriate patient body part or parts into the appropriate cushion(s) 50 and then, using a rotational device, for example, a powered socket driver, lift the patient's body part to any desired height within the range of the lift's capabilities.
Accordingly, at least one feature of the medical lift and positioning device and methods of use is its ability to enable a single attendant to comfortably maneuver, reposition, roll, lift and/or prop a body part of a large bedridden patient with no other tool needed. In some embodiments, only a strap, for example, a dual clamp locking strap attached to a footboard to form a loop, may be needed to comfortably maneuver, reposition, roll, lift and/or prop a body part of a large bedridden patient. The device itself may be designed for such ease of maneuverability.
In some embodiments, multiple devices 100 may be used to lift and prop more than one patient body part at a time.
In some embodiments, the device 100 provides an efficient, lightweight, highly maneuverable and safe apparatus for the lifting, propping and repositioning of patients, for example, bedridden patients.
In some embodiments, the device 100 enables a single person to quickly and/or efficiently prop a person, for example, a bedridden patient, on either of the patient's sides to maintain patient comfort, facilitate patient examination, and to prevent bed sores from forming.
In some embodiments, the device 100 provides a compact, disassemble able, light and portable apparatus that may be easily stored and transported to a patient's home or hospital room.
In some embodiments, the device 100 assists with bedridden patient rolling, positioning, repositioning, and tilting a bedridden patient from side-to-side and may position, reposition and tilt a particular body part of a patient at various angles between the horizontal and vertical axis.
In some embodiments, the device 100 relieves stress on the fingers, hands, arms, back, shoulders and wrists of the caregiver, especially when the patient is heavy.
In some embodiments, the device 100 accommodates different sized bedridden patients, for example, by use of different sized cushions.
In some embodiments, device 100 and/or the cushions 50 may include one or more limb fastening straps, for example Velcro® straps. In some situations, the limb fastening straps may be utilized to hold a limb, for example, an arm, in place on the cushion 50.
In some embodiments, the device 100 conform to a side laying patient's back, shoulder, torso, hips, and upper legs.
In some embodiments, the device 100 provides a low-cost alternative to systems for lifting, propping, securing and turning a bedridden patient, such as, mechanical means for lifting and turning, including mechanical rollers supported by a stationary or moveable support structure, for example, a heavy steel stationary or moveable support structure, positioned above a hospital bed.
In some embodiments, the device 100 provides a support assembly capable of supporting a patient, for example, a bedridden patient, in an angled position on their side to enable additional positions so that the patient may rest on his or her side to reduce bed sores and to increase comfort of the bedridden patient.
In some embodiments, the device 100 may be utilized with existing beds or bed frames.
In some embodiments, the device 100 may be easier, less expensive, smaller, more expandable, lighter and simpler to use than existing technology.
In some embodiments, the device 100 may be independent of attachment to a ceiling, wall or floor thereby making the device capable of being freely transported and capable of being used in a wide variety of environments, including, for example, on the ground to aid a bleeding soldier by elevating the bleeding injury above the soldier's heart.
In some embodiments, the device 100 is configured to be easy to assemble and disassemble and may fit under a bed, or in a duffel bag for easy transport.
