Description
FIELD OF THE INVENTION

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.


INTRODUCTION

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.


STATE OF THE ART

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, table tops, 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.


BRIEF SUMMARY

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 rests 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, prevents 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.


Another feature of the medical lift and positioning device and methods of use is its ability to provide an efficient, lightweight, highly maneuverable and safe apparatus for the lifting, propping and repositioning of patients, for example, bedridden patients.


Another feature of the medical lift and positioning device and methods of use is a high friction rubber sheet at the bottom of the front base which enables the lift to grip the sheets. In some examples, a high-friction spray may be applied to the bottom of the front base to allow the lift to grip the sheets.


Another feature of the medical lift and positioning device and methods of use is its ability to aid healing by holding broken bones and muscles, for example, arm muscles, at specified heights and angles securely in a body part contoured cushion attached to the lift.


Still another feature of the medical lift and positioning device and methods of use is its ability to enable a single person to quickly and/or efficiently prop a bedridden patient on either of the patient's sides (e.g. to turn the patient) to maintain patient comfort, facilitate patient examination, and to prevent bed sores from forming.


Yet another feature of the medical lift and positioning device and methods of use is its ability to provide a compact, disassemble able, light and portable apparatus that is easily stored and transported to the patient's home or hospital room.


Yet another feature of the medical lift and positioning device and methods of use is its ability to aid in drinking and eating by lifting a patient to prone position without the need to use expensive hospital lift beds.


Yet another feature of the medical lift and positioning device and methods of use is its ability to assist with bedridden patient rolling, positioning, repositioning, and tilting from side-to-side as well as its ability to position, reposition and tilt a particular body part of a patient at various angles between the horizontal and vertical axis.


Yet another feature of the medical lift and positioning device and methods of use is its ability to relieve stress on the fingers, hands, arms, back, shoulders and wrists of the caregiver, especially when the patient is heavy.


Yet another feature of the medical lift and positioning device and methods of use is its ability to accommodate different sized bedridden patients.


Yet another feature of the medical lift and positioning device and methods of use is its ability to conform to a side laying patient's back, shoulder, torso, hips, and upper legs.


Yet another feature of the medical lift and positioning device and methods of use is its ability to aid during physical therapy activities by using a rotational motor to flex body parts (e.g. calves) to and fro to provide blood flow and muscle growth.


Yet another feature of the medical lift and positioning device and methods of use is the ability to easily disinfect the material used to form the lift and the cushions with over the counter cleaning sprays or liquids. For example, the lift may be formed of a metal or carbon fiber material and the cushions may be formed of ethylene-vinyl acetate (EVA), which may be easily disinfected by users, for example, a nurse or medical assistant. This may prevent the passage of viruses and other diseases from patients to medical personnel such as nurses.


Yet another feature of the medical lift and positioning device and methods of use is its ability to provide 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 positioned above a hospital bed.


Yet another feature of the medical lift and positioning device and methods of use is its ability to provide a support assembly capable of supporting a bedridden patient in an angled position on their side to enable additional positions to rest on their side to reduce bed sores and to increase comfort of the bedridden patient.


Yet another feature of the medical lift and positioning device and methods of use is its ability to be placed at the foot of the bed on the floor, for example, at a user's home. For example, the device may be placed adjacent to a bed to support the head and/or neck of the user by use of a cushion configured for use with a face down patient, allowing the user's spine to properly align after height adjustment.


Yet another feature of the medical lift and positioning device and methods of use is its ability to be utilized with existing beds or bed frames.


Yet another feature of the medical lift and positioning device and methods of use is its ability to be easier, less expensive, smaller, lighter and simpler to use than existing technology.

DETAILED DESCRIPTION OF THE DRAWINGS

In describing the exemplary embodiments of the present disclosure, as illustrated in FIGS. 1-14 specific terminology is employed for the sake of clarity. The present disclosure, however, is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents that operate in a similar manner to accomplish similar functions. Embodiments of the claims may, however, be embodied in many different forms and should not be construed to be limited to the embodiments set forth herein. The examples set forth herein are non-limiting examples, and are merely examples among other possible examples.


In accordance with embodiments of the present invention, a lift and positioning device 100 may include a base 11, a lift 14, a joint or radial adjustment head 41, and a cushion mount 30. In some embodiments, the height of the lift 14 is adjustable. In some embodiments, the lift 14 is formed as a bypass and is configured to maintain a static height. The bottom of the bypass may be configured with attachment points for connection of the bypass to the base 11. For example, the attachment points may be holes or openings configured to receive the pegs 9 disposed on the base 11.


Referring now to FIG. 1, by way of example, and not limitation, there is illustrated an exemplary embodiment of the medical lift and positioning device 100. As shown in FIG. 1, the medical lift and positioning device 100 may include a front base or base plate 11. The front base 11 may be rectangular in shape and horizontally configured to lay at rest upon a bed (not shown here). In any embodiment, the base or base plate 11 may be formed in any suitable shape including, for example, circular, oval, square, diamond or hexagonal. In an exemplary embodiment, the base plate 11 may be thin and configured to approximate 6 inches wide and 16 inches in length. The configuration is subject to change within a range reasonable to one skilled in the art. The base plate 11 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 some embodiments, the base 11 may be permanently attached to the lift 14. In some embodiments, the base 11 may be releasably attached to the lift 14. In some embodiments, the lift 14 may be configured to swivel or rotate relative to the base 11. In some embodiments, the base 11 may include one or more lift attachment points. In some embodiments, the lift attachment points may be configured as pegs 9. In some embodiments, the pegs 9 may be bullet shaped. In some embodiments, the base plate 11 may be formed with a plurality of perforations 10. In some examples, the perforations 10 may be configured to receive spike members 44 (shown in FIGS. 12a-12c) adapted to secure the base 11 to a support surface, for example, a field, while the device 100 is in use. The spike members 44 may be formed with a sharp end and an attachment end. The sharp end may be configured to be inserted into the support surface, for example, a field or section of the ground, and the attachment section may be inserted into a perforation 10 to connect the spike member 44 to the bottom of the base 11. In some embodiments, the attachment section of the spike members 44 includes a pair of tabs configured to pinch a perforation side wall in order to reversibly secure a spike member 44 to the perforation 10. As shown in FIGS. 12a-12c, the spike members 44 may be configured in a plurality of configurations wherein the top end of the spike member 44 is formed with an attachment component and the bottom end is formed with a sharp component.


Upon the base plate 11 may lay the lift 14. In some embodiments, the mechanical jack or “lift” 14 may be reversibly coupled to the base plate 11. In accordance with embodiments of the present invention, the lift 14 may comprise a lower support member 12, a screw 8, a rear base 5, a pivot module 3, a lever arm 17, and one or more bracket members 27. In some embodiments, the lift 14 may include a joint 35 configured to connect to a cushion mount 30.



FIG. 2 shows an exploded view of an example embodiment of the medical lift and positioning device assembly. As shown in FIG. 2, the lower support member 12 part of the lift 14 may reversibly couple to the base plate 11. The lower support member 12 may comprise one or more legs or bars. A first leg 15 may have one or more holes (not shown) on its bottom wherein one or more pegs 9 of the base 11 may be fitted in the first leg 15. As shown in the depicted example, the support section may be “T” shaped. For example, protruding from a middle section of the first leg 15 may be a second leg 21. In any embodiment, the support section may be formed in any other configuration suitable of supporting the lift 14.


As further shown in FIG. 2, the second leg 21 of the lower support member 12 is configured as a shaft having one or more telescoping components. For example, the second leg 21 may be formed as an external shaft and may house an internal shaft 24 which may be extended or shortened as it protrudes from the second leg 21. In some embodiments, the internal shaft 24 may include a hollow internal component 26, for example, a hollow internal chamber having an internal threaded portion.


In accordance with embodiments of the present invention, the screw 8 of the lift 14 may be formed with an external threaded portion adapted to engage with an internal threaded portion within the lower support member 12. For example, the screw 8 may be configured to engage with the internal thread of the hollow internal chamber 26. In accordance with embodiments of the present invention, the lift may be moved from a first position, wherein the lift is in its collapsed form (as shown in FIGS. 3-10, for example), to a second position, wherein the lift is in its partially to fully expanded position (as shown in FIG. 1, for example), by threadably engaging the screw 8 with the internal chamber 26 of the lower support member 12, for example, by rotating or tightening the screw 8, to draw the internal shaft 24 towards the external shaft 21 and direct the rear base 5, which is disposed a distance away from the front base 11, closer towards the front base 11.
