## Background
PRIORITY CLAIM
Benefit is claimed of U.S. Provisional Patent Application 60/742,843 filed on Dec. 5, 2005, which is herein incorporated in its entirety for all purposes.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to patient transportation, and more particularly to backboard lifting devices.
2. Related Art
Emergency medical personnel, such as paramedics with ambulance services or fire departments, commonly transport victims or patients from an accident scene to a hospital. Backboards are commonly used to immobilize the spine of the patient during transport. Such backboards are typically flat, stiff boards that are sized to carry patients in a prone or supine position. Usually, these backboards have handles or handholds located around the periphery of the board. Thus, in use, a patient lies on the board and medical personnel lift the board with the patient to place them on a stretcher or gurney.
Because backboards are generally flat and only a few inches tall, lifting the board usually requires medical personnel to bend over, or squat down, near the board in order to grasp the handles of the board. Lifting a substantial load, such as a patient, from a bent or squatting position puts tremendous strain and loading on the back of the lifting personnel. Additionally, backboards often only need to be lifted to the height of a lowered gurney, or approximately eighteen inches, so that the gurney can be slid under the backboard to carry the patient.
Lifting a backboard to this height does not allow the medical personnel lifting the backboard to completely straighten up, but instead requires the lifter to remain in a bent or semi-bent position while sustaining the load of the patient until a gurney is placed under the backboard. Sustaining such a load in a bent position increases the strain on the lifters back and can result in injury to the lifter. Furthermore, medical personnel lifting in such a manner can become unstable or lose their balance and cause further injury to the patient.
SUMMARY OF THE INVENTION
It has been recognized that it would be advantageous to develop a method and device that reduces the bending required by the lifter in order to lift a patient on a backboard. In addition, it has been recognized that it would be advantageous to develop a method and device to reduce back injuries or strain from lifting a patient on a backboard. In addition, it has been recognized that it would be advantageous to develop a method and device to lift a patient on a backboard onto a gurney.
The present invention provides for a patient transportation device including a rigid backboard with means for securing a patient thereon. At least one retractable handle can be extendibly and retractably coupled to the backboard, and at least one connector can be coupled between the backboard and the at least one handle to suspend the backboard from the handle when the handle is extended from the backboard.
The present invention also provides for a patient transportation device including a rigid backboard with means for securing a patient on the backboard. At least one stowable handle is extendibly coupled to the backboard, and extendible between a stowed position fixed with respect to the backboard and an extended position removed from the backboard.

DETAILED DESCRIPTION 
Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
The present invention provides for a patient transportation device for transporting patients and especially those with spinal, head or neck injuries. The patient transportation device includes a backboard that has handles that can be removed or extended from the backboard to provide a mechanical advantage when lifting the backboard with the patient thereon. The handles are connected to the backboard by extendible connectors, such as cords or hinged rods. The length of the connectors can position the handles to an elevation above the backboard that allows medical personnel to more easily lift the backboard from off the ground, thus resisting back injury or back strain. The handles and connectors can be manually or automatically retractable or stowable to the backboard so that the connectors and handles will not interfere with the operation or transportation of the backboard when not being used to lift the backboard.
As illustrated in FIGS. 1-9, a patient transportation device, indicated generally at 10, in accordance with the present invention is shown for use in transporting injured patients. The patient transportation device 10 can include a rigid backboard 11 sized and shaped to accommodate a patient, as is commonly used in securing patients with head, neck or spinal injuries. The backboard can be any type of backboard for transporting patients, including split boards or scoops. The backboard 11 can have a plurality of handholds 12 disposed around a perimeter thereof. The backboard 11 can have an uppermost surface 14 that can support a patient in a prone or supine position. The backboard 11 can have a general rectangular shape including two shorter ends 16, and two longer lateral sides 18. It is understood that the longer lateral sides can taper, as is known in the art. The handholds 12 can be spaced around the backboard 11 along the ends 16 and sides 18. The handholds 12 can be apertures or holes extending through the backboard 11 sized to receive the fingers and/or palm of a user. The backboard 11 can be formed of a material that will not interfere with x-rays, such as fiberglass, composites, wood, and the like, so that x-ray equipment or the like can be used while the patient is secured to the backboard.
The backboard 11 can have straps 70 (FIG. 3) with buckles 72 for securing or strapping the patient to the backboard. The straps 70 with buckles 72 are one means for securing a patient to the backboard 11. The straps can also be means for immobilizing a patient on the backboard. Other means, as known in the art, can also be used to secure patients to the backboard of the patient transportation device 10.
The patient transportation device 10 can also include a plurality of removable, extendable and/or stowable handles 20 removably and extendably coupled to the backboard 11 and stowable in a fixed relationship to the backboard. The handles 20 can be spaced around the backboard 11 along the ends 16 and sides 18, or at the corners. The handles can have a hole 27 for facilitating grasping of the handle. Thus, as illustrated in FIGS. 1-5, a pair of handles 20 can be located on one end of the patient transportation device 10, and another pair of handles 20 can be located on the opposite end of the patient transportation device 10.
The backboard 11 can also includes a plurality of handle receptacles 24 sized and shaped to receive the plurality of handles 20. The handle receptacles 24 can be recesses in the upper surface 14 of the backboard 11 that are positioned around a peripheral edge 28 of the backboard. The recesses 24 can be sized and shaped to house or stow each of the plurality of handles 20 and position the handles approximately flush or below the plane of the upper surface 14. Thus, the handles can be flush or within a normal perimeter or envelope of the backboard so that they do not interfere with operation of the backboard.
The receptacles or recesses 24 can have an undercut 80 with the top surface 14 of the backboard 11 extending over or overlapping the undercut, and thus the handle. The removable handles 20 can have a similar shape as the undercut 80 so that a portion 82 of the handle fits into the undercut and the upper surface 14 of the backboard 11 overlaps at least a portion 82 of the handle 20. Advantageously, the undercut helps to guide the handle 20 back into the handle receptacle 24 when the handle is retracted. It will be appreciated that other designs or shapes can be used to guide the handles.
At least one connector 40 is extendibly coupled between the backboard 11 and the handles 20. The connector can be any means for connecting the handles to the backboard. For example, the connector can be flexible cords, flexible tubing, flexible straps, rods, a linkage of rods, and the like.
One end 44 of the connector can be coupled to the backboard device 10 and the other end 48 of the connector can be coupled to the handles 20. The connectors 40 allow the handles 20 to be removed or extended from the backboard, while still coupling the handles to the backboard. Thus, the handles 20 can be elevated with respect to the backboard prior to lifting so that emergency personnel are in a better position for lifting. In one aspect, a plurality of connectors 40 can be spaced around the backboard 11 and can correspond in position to the spacing of the handles 20. In this case, each one of the plurality of connectors 40 can be associated with one of the plurality of handles 20. For example, as shown in FIG. 7, each handle 20 can have a small aperture 84 through which the connector 40 can extend. The aperture 84 can have a wider end 88 and the end of the connector 48 can have means for stopping and retaining 86 the connector end 48 in the wider end 88 of the aperture 84. In the case the connector is a flexible cord, the means for stopping can be a knot tied in the flexible cord, or an enlargement coupled to a flexible cord. In the case where the connector is a rod or linkage of rods, the rod can be coupled to the handle by a fastener, such as a bolt, screw, and the like.
The handles 20 and/or connectors 40 can be extendible between an extended or elevated position, as shown in FIG. 2, and a retracted or stowed position, as shown in FIG. 1. In the extended position, the connectors 40 are extended out of the backboard 11 to a predetermined length and the handles are elevated to a predetermined elevation. The predetermined length can position the handles 20 at a more comfortable and ergonomic position for lifting the patient transportation device 10. In one aspect, the predetermined length can be approximately 18 inches. Thus, the connectors 40 can suspend the backboard 11 below the handles 20 when the handles are removed and pulled away from the backboard to extend the connectors 40 to the extended position. A stopper 68 can be formed at the end 44 of the connector 40, similar to that at the other end 48 near the handles, to engage the backboard so that the backboard is suspended from the connector 40. The stopper can be larger than a hole in the backboard through which the connector passes.
The connectors 40 and/or the handles 20 are also retractable to or stowable with respect to the backboard 11. In the retracted or stowed position, the handles 20 are fixed with respect to the backboard. For example, the handles 20 can be adjacent or abutting the backboard, or can be nested within the handle receptacles 24. In addition, the connectors 40 can be stowed within the backboard. The handles 20 can be located adjacent to or in the backboard 11. The connectors 40 and handles 20 can be manually or automatically retractable.
The connectors 40 can include flexible cords, such as cable or nylon rope or straps. The flexible cords can suspend the backboard 11 from the handles 20 and allow the backboard to swing from the handles 20. Advantageously, allowing the backboard 11 to swing from the handles 20 can provide a smoother motion to the patient being transported on the patient transportation device 10 during lifting and turning of the backboard 11. The connectors 40 can be or can include elastic in order to retract the handles as described below.
The handles 20 and connectors 40 can be formed of a material that will not interfere with x-rays so that x-ray equipment or the like can be used while the patient is strapped to the backboard.
As shown in FIGS. 6-8, the patient transport device 10 can also include means for retracting the connectors 40 to a retracted or stowed position with respect to the backboard 11. For example, a biasing device 60 can bias the plurality of connectors 40 and the handles 20 to the retracted or stowed position. The biasing device 60 can be coupled between a pair of connectors 40, and can bias both connectors to the retracted position. Specifically, one connector 40 can be positioned on one end 16 of the backboard 11 and another connector 40 can be positioned on the opposite end 16 of the backboard 11 and the biasing device 60 can inter-couple the two connectors 40.
In one aspect, the biasing device 60 can be a spring. The connectors 40 can be inelastic cords. Thus, as the connectors 40 are pulled to the extended position by the handles 20, the spring 60 can stretch and allow the connectors 40 to extend away from the backboard 11. Similarly, when the handles 20 are released the spring 60 can return to an un-stretched state, thereby retracting the connectors 40 into the backboard, and retracting the handles to the stowed position. The spring 60 can be housed in a preformed channel 64 within the backboard 11. The stoppers 68 can be positioned on the connectors 40 at predetermined positions to restrict extension of the connectors 40 to a predetermined length.
The spring 60 is one example of a means for retracting the connectors 40 and handles 20 to the retracted position. Other means for retracting can also be used for retracting the handles 20 with respect to the backboard 11. For example, the biasing device can be an elastic cord, a pneumatic cylinder, a hydraulic cylinder, a linear spring, a coiled spring, and combinations of these devices. It will be appreciated that the biasing device 60 can be formed of a material that will not interfere with x-rays, such as elastic cord, so that x-ray equipment or the like can be used while the patient is strapped to the backboard 11. It will also be appreciated that the connectors, such as one or more rods, can be manually retracted into the backboard.
It will be appreciated that movable parts such as the retractable handles and biasing device 60, and load bearing parts such as the connectors 40 will experience wear and tear due to use. Advantageously, such parts can easily be removed and replaced on the patient transportation device 10 of the present invention. Replacing worn parts in this manner provides a low cost alternative to replacing the entire backboard. In one aspect, a handle and means for retracting a connector and the handle can be provided as a unit that can be added to a backboard.
Referring to FIGS. 7-9, the backboard 11 can have a channel 92 extending longitudinally along the length of the backboard and open, or partially open along the length, on a bottom side 4. The connector 40 and retracting means can extend through the channel 92. A cap 94 can be placed over the channel to cover the channel and retain the connector and retracting means in the backboard 11. Advantageously, the cap 94 can extend along the bottom 4 of the backboard 11 in a longitudinal direction and can act as a track or rail upon which the backboard can slide or rest upon a support surface.
In use, the patient transportation device 10 is placed on the ground or other support surface near an injured person or patient. The patient is then moved and secured to the backboard 11. Medical personnel can then move to a low position close to the backboard 11 such as kneeling down, squatting, or bending over near the backboard. The handles 20 can then be removed from the backboard 11, and the connectors 40 can be pulled out to the extended position. In addition, the handles can be pulled against the means for retracting the at least one handle. Once in the extended position, the medical personnel can arise from the low position to a near standing position. The medical personnel can then straighten their own backs and bend their legs in order to maintain their grasp of the handles 20. From this semi-standing or semi-squatting position, the medical personnel can lift the backboard 11 and patient simply by straightening their legs and rising to a full standing position. In this way, the present invention provides great ergonomic benefit and advantage to medical personnel when lifting a backboard 11 and patient, since the load of the patient can be carried by the medical personnel's legs and not by their backs or outstretched arms.
It will be appreciated that, while the retractable handles of the present invention are shown in FIGS. 1-9 coupled only to a standard backboard, the concept of such handles can be applied to other types of backboards as well. For example, retractable handles could be used on split backboards, snow sled backboards, scoop backboards, and the like.
