This invention relates to transfer assist devices and more particularly, to a device for a patient gurney which facilitates transferring a patient on a stretcher onto and off of, a medical helicopter or other transport vehicle to prevent injuries to medical personnel transferring the patient.
When a patient is transported from one location to another, or one vehicle to another, and more particularly when a patent is moved onto/or off of a helicopter, the patient is generally placed onto a stretcher. The stretcher is then loaded onto a helicopter to transport the patient to a health care facility. Once the helicopter arrives at the health care facility, a wheeled gurney from the health care facility is brought to the helicopter. The stretcher, carrying the patient, is then transferred from the helicopter to the gurney by medical personnel. Although the present invention is primarily directed toward medical helicopter transport, the invention is equally applicable to other means/modes of transportation, including, but not limited to ambulances, fire trucks, wheeled vehicles and other types of aircraft.
While the gurney may be adjustable in height, many gurneys, even when extended to a maximum adjustable height, do not extend up to a patient supporting surface within the helicopter (hereinafter “helicopter loading surface”). The height of the helicopter loading surface varies from aircraft to aircraft and the helicopter loading surface may be on the floor of the helicopter, or may be on top of a platform with drawers and/or storage underneath. Many times there is a material vertical height difference between the helicopter loading surface and the top surface of the gurney. This height differential requires that medical personnel physically, and simultaneously, lift and move the stretcher, and the patient, and attached medical equipment, from a first position, to a second position. The simultaneous lifting and moving subjects medical personnel, including the helicopter pilot, to workplace injuries and presents risks to the patient being transferred.
My invention provides a gurney transfer assist device. The invention has a fixed height frame supporting a slidably movable bed deck frame. The fixed height tubular box frame is releasably secured to a known wheeled gurney. The fixed height dimension raises a carried stretcher a vertical height sufficient to allow loading/unloading onto a helicopter. The slidably movable bed deck frame is extendable outwardly from one end of the fixed height frame and the extending end is angulated to facilitate transfer of the stretcher and supported patient to/from the helicopter and to provide adequate “space” for multiple persons to assist in the transfer.
The fixed height frame has a lower rectilinear frame member and a spaced apart upper rectilinear frame member. Each of the lower and upper frame members have two opposing parallel end portions and two opposing parallel lateral side portions. The opposing parallel lateral side portions are longer than the end portions. The lower and upper rectilinear frame members are structurally interconnected to one another by plural frame supports. Cross bracing extends between the opposed parallel lateral side portions of each frame member to maintain rigidity. The fixed height frame provides a fixed vertical height dimension which is approximately 12 inches between the upper and lower frame members. The upper frame member carries an adjustment rack that operatively cooperates with a corresponding adjustment member to control extension and retraction of a slidably movable bed deck frame carried by the fixed height frame.
The bed deck frame has two opposing and spaced apart end portions, and two opposing, and spaced apart, parallel lateral side portions. Cross braces extend between the lateral side portions to provide rigidity and strength. A handle end carries an upwardly arched handle and is generally perpendicular to the lateral side portions. An opposing foot end, is angulated and is not parallel to the handle end portion. The angled foot end eases transfer of a supported stretcher/patient onto/off of the helicopter by allowing the wheeled gurney to be positioned relative to the helicopter so that the stretcher may be “slidably moved” onto/off of the helicopter and onto/off of the bed deck frame. The angulation of the foot end reduces the need for medical personnel to physically lift and simultaneously move the stretcher from one position to another position and facilitates the “sliding” of the stretcher and patient, and may also align the patient and/or stretcher with a designated patient supporting surface within a medical transport vehicle. The parallel lateral side portions of the bed deck frame (on the bottom surface) carry slider brackets that support slide members so that the bed deck frame freely translates along the side members of the fixed height frame. A latch assembly is carried on the underside of the bed deck frame and releasably engages with the adjustment rack carried by the fixed height frame. An operator, using a handle attached to a lever can optionally engage/disengage the latch assembly from the adjustment rack. When disengaged, the bed deck frame is slidable along the fixed height frame from a first (retracted) position to a second position. In the first retracted position, the bed deck frame is generally centered upon the fixed height frame (and centered on the supporting gurney). In the second extended position, the bed deck frame extends a distance of approximately twenty-two inches endwardly from the fixed height frame in the direction of the foot end of the bed deck frame. This endwardly extension of the bed deck frame facilitates transfer of the stretcher/patient from the invention onto/off of the helicopter even when the wheeled gurney (not shown) is prevented from moving closely to the helicopter because of the helicopter skids/structure.
A generally planar load supporting deck is carried by the bed deck frame between the opposing end portions and between the parallel lateral side portions. The load supporting deck is comprised of a material that is not absorbent, easily cleanable and is “slippery” so that a stretcher may easily slide thereon and therealong. A puck receiver is defined in the load supporting deck generally medially between the opposing parallel lateral side portions and spacedly adjacent the handle end portion. The puck receiver is configured to releasably engage with an outwardly extending puck that is an integral component of many patient stretchers used in medical helicopters. A similar puck receiver is commonly carried within many medical helicopters so as to positionally secure a stretcher to the helicopter loading surface.
The load supporting deck is large enough to also support medical equipment that may be “attached” to the patient and necessary during the transport, such as, but not limited to respirators, IV fluid racks, and the like.
In use, the fixed height frame is supported upon a wheeled gurney on an upper surface thereof. The fixed height frame may be attached to the gurney with flexible straps that communicate between the fixed height frame and the gurney. In one contemplated embodiment, frame supports may define through slots configured to receive fastening straps. The fixed height frame provides an additional approximately 12-inch height to the standard wheeled gurney.
When moving the patient, upon the stretcher, onto/off of a medical helicopter, the wheeled gurney is positioned as close as possible to an open helicopter door. Typically helicopter skids, which extend laterally outwardly from the helicopter, prevent the wheeled gurney from being positioned immediately adjacent to the helicopter door/deck. Once the wheeled gurney is positioned as close as possible to the helicopter, which may be immediately adjacent the helicopter skid, the medical personnel may secure the wheel brakes on the gurney and then may disengage the latch mechanism to slide the bed deck frame and load supporting deck, (carrying the stretcher and patient) toward the second extended position whereupon the foot end of the bed deck frame physically contacts the helicopter loading surface. The gurney may be oriented angularly relative to the helicopter such that a corner portion of the stretcher carrying the patient is positioned directly upon the helicopter loading surface. (This orientation is facilitated by the angular configuration of the bed deck). The stretcher carrying the patient may thereupon be slidably moved along the load supporting deck and on to the helicopter/off of the helicopter without any lifting of the stretcher and/or patient.
The angulation of the foot end also allows more than only two medical personnel to position themselves immediately adjacent the helicopter door and the stretcher during patient transfer which assists in sharing the weight/load and provides more “hands” to assist in the transfer which enhances safety.

This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).
As shown in the accompanying Figures, my transfer assist device provides a fixed height frame 10, supporting a slidably movable bed deck frame 50 that carries a patient supporting deck 80.
The fixed height frame 10 is releasably secured to a known wheeled gurney (not shown). The fixed height dimension raises a carried stretcher (not shown) to a vertical height to allow loading/unloading of a patient and supporting stretcher onto a medical helicopter 100.
The fixed height frame 10 is a rectilinear frame structure having a lower frame member 11 and a spaced apart upper frame member 12. The lower frame member 11 and the upper frame member 12 are formed of beams which may be, but are not limited to, box beams, and/or tubular beams, and/or sheet metal that has been bent into the configuration of a beam. Each of the lower 11 and upper 12 frame members have two opposing parallel end portions 11A, 11B, 12A, 12B and two opposing parallel lateral side portions 11C, 11D, 12C, 12D. The parallel lateral side portions 11C, 11D, 12C, 12D are longer in length dimension than the end portions 11A, 11B, 12A, 12B. The end portions 11A, 11B of the lower frame member 11 are structurally interconnected to the parallel lateral side portions 11C, 11D at the adjacent end portions thereof to form the rectilinear lower frame member 11. Similarly, the end portions 12A, 12B of the upper frame member 12 are structurally interconnected to the parallel lateral side portions 12C, 12D at the adjacent end portions thereof, to form the rectilinear upper frame member 12.
The lower frame member 11, and the upper frame member 12, are structurally interconnected to one another by plural, spacedly arrayed, frame supports 13 that extend between an upper surface of the lower frame member 11 and a bottom surface of the upper frame member 12. The plural spacedly arrayed frame supports 13 provide the fixed/predetermined vertical height dimension which is approximately about twelve inches between the upper 12 and lower 11 frame members. Plural cross braces 14 are spacedly arrayed between, and extend between the parallel lateral side portions 11C, 11D, 12C, 12D of the frame members 11, 12 for strength and rigidity.
An adjustment rack 40 is carried by the upper frame member 12 adjacent an upper edge thereof. The adjustment rack 40 has a plurality of spacedly arrayed, upwardly extending engagement teeth 41 that adjustably engage with a cooperating latch assembly 60 to control movement of, and to positionally secure, a slidably movable bed deck frame 50 carried by the fixed height frame 10.
The slidably movable bed deck frame 50 is extendable outwardly from a first foot end 16 of the fixed height frame 10 and the supporting wheeled gurney (not shown), to facilitate transfer of the stretcher and supported patient to/from the helicopter 100.
The slidably movable bed deck frame 50 has a frame 51 which may be formed of tubular beams, and/or box beams, and/or bent sheet metal. The frame 51 has a foot end 52, a handle end 53, and two opposing and spaced apart parallel side portions 54, 55. Strengthening braces 56 extend between the parallel side portions 54, 55 to provide rigidity and strength. The handle end 53 carries a handle 57 that extends generally perpendicularly upwardly relative to the bed deck frame 50 and is generally perpendicular to the parallel side portions 54, 55. The foot end 52 is opposite, and spaced apart from, the handle end 53 and is angulated. The foot end 52 is preferably not parallel to the handle end 53. As shown in
Slide brackets 58 are carried on bottom surfaces of the parallel side portions 54, 55 of the bed deck frame 50. The slide brackets 58 carry slide members 59, which are movement means, and may be, but are not limited to linear bearings, slider blocks formed of nylon or UHMD plastic, other known material, or roller wheels on axles so that the bed deck frame 50 freely translates along the side members 12C. 12D of the upper frame member 12 of the fixed height frame 10. The slide members 59 may be positioned adjacent above the side members 12C, 12D of the upper frame member 12 so that the bed deck frame 50 is supported thereon, and slide members 59 may be positioned adjacent below the side members 12C, 12D of the upper frame member 12 so that the bed deck frame 50 cannot be lifted from/vertically detached from the fixed height frame 10. In the preferred embodiment, slide members 59 are positioned both immediately above, and immediately below the side members 12C, 12D of the upper frame member 12.
A latch assembly 60 is carried on the underside of the bed deck frame 50 and is configured to releasably engage with the adjustment rack 40 carried by the fixed height frame 10. A handle 61 controls operation of the latch assembly 60 and an operator, using a handle 61 can optionally engage/disengage the latch assembly 60 from the adjustment rack 40. When disengaged, the bed deck frame 50 can freely translate along the fixed height frame 10 between a first centered position (
A generally planar load supporting deck 80 is carried by, and secured to, the bed deck frame 50 between the foot end 52 and the handle end 53 and between the parallel lateral side portions 54, 55. The load supporting deck 80 is comprised of a material that is not absorbent, easily cleanable, and is “slippery” so that a stretcher (not shown) may easily slide thereon and therealong. The load supporting deck 80 is dimensioned and configured to be large enough to also support medical equipment (not shown) that may be “attached” to the patient and necessary during the transport, such as, but not limited to respirators, IV fluid racks and the like.
A puck receiver 90 is defined in the load supporting deck 80 generally medially between the opposing parallel lateral side portions 54, 55 and the spacedly adjacent the handle end portion 53. The puck receiver 90 is designed and configured to releasably engage with an outwardly extending puck (not shown) that is an integral component of many patient stretchers used in medical helicopters 100. Puck receivers are carried in many medical helicopters to secure a stretcher to the helicopter loading surface therein. The puck receiver 90, has a spring biased lock 95, that when in an unlocked position, is planar with a top surface of the load supporting deck 80. When the puck (not shown) carried on a bottom surface of the stretcher (not shown) passes through puck receiver opening 94, guided by first and second engagement guides 91, 92 and into engagement with puck anchor head 93, an operator may activate a handle that releases the spring biased lock 95 which moves the lock 95 into engagement with the puck (not shown) to prevent the puck (and the attached stretcher—not shown) from moving or disengaging from the puck receiver 90 until the spring biased lock 95 is released by an operator.
In use, the fixed height frame 10, and the bed deck frame 50, are supported by, and secured to a standard wheeled gurney on an upper surface thereof. The fixed height frame 10 may be attached to the gurney by means of flexible straps (not shown) that communicate between the fixed height frame 10 and the gurney. In one contemplated embodiment, the frame supports 13 define through slots 15 configured to receive fastening straps (not shown). The fixed height frame 10 provides an additional approximately 12-inch height to the standard wheeled gurney.
A further aspect of the present invention relates to a transfer assist device for transferring a stretcher (not shown) carrying a patient from a wheeled gurney (not shown) to a helicopter 100 loading surface, and from a helicopter 100 loading surface to a wheeled gurney, the transfer assist device comprising: a fixed height frame 10 having a lower frame member 11 and an upper frame member 12.
The lower frame member 11 is generally rectilinear in peripheral configuration and has two opposing parallel and spaced apart end portions 11A, 11B formed of beams, and two opposing and spaced apart parallel lateral side portions 11C, 11D formed of beams, and the two opposing parallel and spaced apart lateral side portions 11C, 11D are longer in a length dimension than the parallel and spaced apart end portions 11A, 11B, and the end portion beams 11A, 11B and the lateral side portion beams 11C, 11D are structurally interconnected to one another at adjacent end portions, and plural cross braces 14 extend between the parallel spaced apart lateral side portions 11C, 11D.
The upper frame member 12 is generally rectilinear in peripheral configuration and has two opposing parallel and spaced apart end portions 12A, 12B formed of beams, and two opposing parallel and spaced apart lateral side portions 12C, 12D formed of beams, and the two opposing parallel and spaced apart lateral side portions 12C, 12D are longer in a length dimension than the parallel and spaced apart end portions 12A, 12B, and the end portion beams 12A, 12B and the lateral side portion beams 12C, 12D are structurally interconnected to one another at adjacent end portions, and plural cross braces 14 extend between the parallel lateral side portions 12C, 12D, and the upper frame member 12 is longer in the length dimension than the lower frame member 11. The upper frame member 12 is structurally interconnected to, and is spaced apart from the lower frame member 11, by a predetermined fixed height distance, by plural spacedly arrayed frame supports 13 that extend between an upper surface of the lower frame member 11, and a lower surface of the upper frame member 12. Each of the plural frame supports 13 defines at least one slot 15 for a securing strap (not shown) to secure the fixed height frame 10 to an upper surface (not shown) of the wheeled gurney (not shown).
An adjustment rack 40 having a plurality of spaced apart and upwardly oriented teeth 41 is carried by the upper frame member 12, adjacent an upper edge of the fixed height frame 10, and the plurality of spaced apart and upwardly oriented teeth 41 facilitate controllable movement, and positional securement, of a slidably movable bed deck frame 50 relative to the fixed height frame 10 between a first centered position (
The slidably movable bed deck frame 50 has two opposing and spaced apart end portions 52, 53, formed of beams, and two opposing and spaced apart parallel lateral side portions 54, 55, formed of beams. In one preferred embodiment, length dimension of the first lateral side portion 54 is different than the length dimension of the second lateral side portion 55 so that the foot end 52 of the bed deck frame 50 is angulated relative to the handle end portion 53. In a second contemplated embodiment, the lateral side portions 54, 55 have the same length dimension so that the bed deck frame 50 is generally rectilinear in configuration.
The slidably movable bed deck frame 50 is slidably carried by the fixed height frame 10 immediately adjacent above the upper frame member 12 and opposite the lower frame member 11.
A handle end portion 53, formed of a beam, extends generally perpendicularly between the two spaced apart and parallel lateral side portions 54, 55 at proximate ends thereof and is structurally interconnected thereto at adjacent end portions. The handle end portion 53 carries an upwardly extending handle 57. A foot end portion 52 formed of a beam, extends between and is structurally interconnected to proximate end portions of the two spaced apart and parallel lateral side portions 54, 55, opposite the handle end portion 53. The foot end portion 52 is preferably not parallel to the handle end portion 53. Strengthening braces 56 are spacedly arrayed between, and structurally interconnect the spaced apart parallel lateral side portions 54, 55.
Plural spacedly arrayed slider brackets 58 are carried on an underside of each parallel lateral side portion 54, 55, and each of the plural slider brackets 58 support at least one slide member 59, which may be, but is not limited to, a linear bearing, a slider block formed of Teflon or nylon or UHMW, or other known material, or a roller wheel on an axle. The slide members 59 slide and/or roll along an upper surface of the parallel lateral side portions 54, 55 of the fixed height frame 10 upper frame member 12.
A generally planar and elongate roller shield 85 is carried by, and depends downwardly from, an underside of the slidably movable bed deck frame 50 adjacent laterally outwardly of the slider brackets 58, spacedly adjacent each lateral side portion 54, 55 of the slidably movable bed deck frame 50, each roller shield 85 has a top to bottom height dimension that is greater than a diameter of the slide member 59, and has a length dimension (end to end) that is greater than the distance between the plural slider brackets 58 carried on one lateral side portion 54, 55 of the slidably movable bed deck frame 50, so as to simultaneously shield the slide members 59 of the spaced apart slider brackets 58 from entanglement, and to prevent unintentional injury to a user.
A latch assembly 60, with an operator handle 61 is carried on an underside of the slidably movable bed deck frame 50, and the latch assembly 60 releasably engages with the spaced apart and upwardly oriented teeth 41 of the adjustment rack 40 carried by the fixed height frame 10.
A generally planar load supporting deck 80, having a top load supporting surface and an opposing bottom surface, is carried by the slidably movable bed deck frame 50 between the foot end 52 and the handle end 53 and between the parallel and spaced apart lateral side portions 54, 55.
A puck receiver 90 is defined in the generally planar load supporting deck 80 generally medially between the opposing parallel and spaced apart lateral side portions 54, 55 and spacedly adjacent the handle end portion 53 to releasably engage with an outwardly extending puck (not shown) of the stretcher (not shown). As shown in
An elongate side rail 69 is carried by the slidably movable bed deck frame 50 adjacent each opposing lateral side portion 54, 55 on plural spacedly arrayed side rail mounting posts 72. Each side rail 69 extends between the foot end 52, and the handle end 53, and is parallel to and spacedly above, the generally planar load supporting deck 80. Each elongate side rail 69 has a first end portion 70, a spaced apart second end portion 71, and a side rail rotation frame 73 between the first end portion 71 and the second end portion 72. The side rail rotation frame 73 rotates axially relative to the side rail 69. The side rail rotation frame 73 carries a generally planar, and pivotally movable slide rail panel 62. Each slide rail panel 62 has a first end portion 63, a second end portion 64, an inner side portion 65, a laterally outer side portion 66, a top surface 67, an opposing bottom surface 68, a hinge edge 78 and a distal edge 79 that is opposite the load supporting deck 80.
Each slide rail panel 62 is movable relative to the load supporting deck 80 between a first locking position wherein the slide rail panel 62 is oriented generally vertically, and generally perpendicular relative to the generally planar load supporting deck 80 providing a physical barrier to retain a patient on the load supporting deck 80, and a second position wherein the slide rail panel is oriented generally coplanar with, and spaced laterally adjacent to, the load supporting deck 80 to facilitate movement of the stretcher and patient thereon, onto and off of the load supporting deck 80, and to a laterally adjacent surface, such as the surgery table or another wheeled gurney. Because the slide rail panel 62 is pivotal to a generally horizontal position, this slide rail panel 62 can provide a “bridge” between two spacedly adjacent surfaces, such as, but not limited to, to adjacent gurneys so that the stretcher and patient may be moved therebetween safely, and always providing a “structure” between the adjacent surfaces to prevent the stretcher and patient from inadvertently falling therebetween.
Having described the structure of my gurney transfer assist device, its operation is briefly described.
Operation of the currently disclosed invention is believed to be readily apparent from the above detailed written description, however a brief description of the operation of the instant invention is nevertheless provided below.
When moving a patient, upon a stretcher, onto/off of a medical helicopter 100, the wheeled gurney (not shown) is positioned as close as possible to an open helicopter door. Typically, helicopter skids 102 which extend laterally outwardly from the bottom of the helicopter 100 prevent the wheeled gurney from being positioned immediately adjacent the helicopter door. (See
Medical personnel (and/or others) may position themselves immediately adjacent the helicopter door and assist in the transfer to/from the helicopter 100. In one possible instance, such as, but not limited to, when the patient needs immediate and continuous attention from more than two medical personnel (such as to stabilize a broken neck or perform continuous chest compressions) the angulation of the foot end portion 53 of the bed deck frame 50 allows more than only two medical personnel to have “hands on” the patient throughout the transfer—the available space is greater. The stretcher (not shown) carrying the patient is thereupon slidably moved along the extended/translated load supporting deck 80 and onto the helicopter loading surface or off of the helicopter loading surface without any lifting of the stretcher and/or patient while allowing the medical personnel to stand upon the underlying supporting ground surface.
