Description

EVACUATION FRAME ASSEMBLYBackground of the Invention

[0001] People may find themselves in need of help in any situation where an emergency stretcher is a critical tool for their safety, including extreme cases such as hurricanes, accidents, earthquakes, mudslides, flood zones, fires, or active shooters. In such a situation, an injured person may require immediate assistance and to be moved to a safer area such as a higher floor, away from the scene of an accident, or to a bunker. While rescuers aim to treat the injured as quickly as possible, it may be dangerous to reach the victims and treat them where they are.

[0002] Thus, in such a situation, it is essential to consider the safety of both the injured and the rescuers, and, therefore, when possible, the patient should be carried to a safer and more stable location, where treatment can be administered safely. However, current apparatuses used in such efforts may require a significant amount of space, be time-consuming, put the helpers at risk, or even cause harm to the victim.

[0003] The existing rescue devices, such as stretchers or blankets, are large and require that there be space beside the patient in order to be able to move the patient to the rescue devices. Some such devices enable the patient to be harnessed thereto, but the patient may need to be dragged onto the device’s surface or may have to be positioned on a single rescuer's back or shoulder.

[0004] In addition, some stretchers or blankets may require more than two rescuers for their use, thereby impairing the view of the rescue route and increasing the overall risk to the rescuers and the patient.

[0005] The device disclosed herein will function as a stretcher while trying to overcome the limitations or disadvantages of each of them while operating in an unstable or unsafe location.Summary of the Invention

[0006] In general, it is an object of the present invention to provide an evacuation frame assembly that is compactly foldable for easy storing and positioning, lightweight and self-contained and can be conveniently transported in the compact, folded condition.

[0007] It is another object of the invention to provide an evacuation frame assembly that can quickly and easily be expanded and arranged around the body of an incapacitated person, without the need to change the position of the patient’s body.

[0008] It is a further object of the invention to provide an evacuation frame assembly that can be adjusted to fit around the body of the patient and carry the patient, no matter how large or small, to another location.

[0009] These and other objects of the invention are accomplished by an evacuation frame assembly that is based on the frame device disclosed in US Patents Nos. 11,744,772 and 12,213,938, entitled Adjustable Automated CPR Positioning Apparatus, by the co-inv enters hereof, but without a chest compression device attached. With some modifications, the device can be used for quick rescue and evacuation of a wounded person.

[0010] The main characteristics of the device serve to enable the features required for being compact, easily assembled, rigid and lockable, and easily size adjustable.

[0011] According to some embodiments, the evacuation frame assembly is a rigid device, compactly folded and ready to be assembled for use. The evacuation frame assembly is arranged as a chain of telescopic rigid rails with size fixing and one lock set at the two most remote elements, easily arranged around the patient, and easily customized for additional support and protection of body parts during the move.

[0012] In some embodiments, an evacuation frame assembly comprises a plurality of rigid telescoping elements connected one to another at respective ends thereof to form a frame chain, wherein each element is adjustable in length and is connected to at least one adjacent element by a hinge; wherein the frame chain is configured to be unfolded from a compact configuration, in which the elements are folded and arranged one against another, to an operable configuration, in which the elements are arranged end-to-end as a frame around a patient’ s torso; at least one length-locking mechanism configured to fix a selected length of at least one of the elements; and a locking mechanism operatively connected to opposing ends of the frame chain to lock the frame into a rigid, operable configuration around a patient; wherein the frame is configured to support and transport the patient to a different location.

[0013] In certain embodiments, the locking mechanism is a latch that connects the two most remote ends of the frame chain.

[0014] In certain embodiments, the at least one length-locking mechanism comprises an individual length setting mechanism that is configured to lock the length of an individual telescoping element or a centralized length setting mechanism that is configured to lock the lengths of a plurality of telescoping elements at once.

[0015] In some embodiments, the centralized length setting mechanism comprises an embedded strap, wire or string extending through the elements and hinges of the frame chain, wherein the strap, wire or string is configured to simultaneously adjust and fix selected lengths of the elements upon actuation. In some embodiments, the strap, wire or string is coupled to a tensioning mechanism to set selected lengths of the elements.

[0016] In certain embodiments, the hinges allow the frame chain to be compactly folded into a compact configuration wherein the elements lie adjacent to each other.

[0017] In certain embodiments, the evacuation frame assembly further comprises a stabilizing support element configured to be attached to a frame element, wherein the stabilizing support element supports and stabilizes the patient around whom the frame is arranged for transport.

[0018] In some embodiments, the stabilizing support element is variable in length and / or width.

[0019] In some embodiments, the stabilizing support element connects two frames, each in an operable configuration around the patient, and supports and stabilizes the patient around whom the frames are arranged for transport.

[0020] In certain embodiments, the evacuation frame assembly further comprises one or more rings or connection points that are configured for use in transporting the patient when the frame is in the operable configuration.

[0021] In some embodiments, the one or more rings are configured for use as handles for transporting the patient when the frame is in the operable configuration.

[0022] In some embodiments, the one or more rings or connection points are configured for attachment of grasping elements. In some embodiments, the grasping elements comprise carrying straps or poles.

[0023] In certain embodiments, the evacuation frame assembly further comprises a stabilizing support element configured to be attached to a frame element, wherein the stabilizing support element supports and stabilizes the patient around whom the frame is arranged for transport; and one or more rings or connection points that are configured for use in transporting the patient when the frame is in the operable configuration..

[0024] In some embodiments, the stabilizing support element connects two frames, each in an operable configuration around the patient, and supports and stabilizes the patient around whom the frames are arranged for transport.

[0025] In some embodiments, the one or more rings are configured for use as handles for transporting the patient when the frame is in the operable configuration.

[0026] In some embodiments, the one or more rings or connection points are configured for attachment of grasping elements. In some embodiments, the grasping elements comprise carrying straps or poles.

[0027] In certain embodiments, the evacuation frame assembly further comprises sliders or wheels that are configured to be attached to a lower rail for use in transporting the patient when the frame is in the operable configuration.

[0028] In certain embodiments, the evacuation frame assembly further comprises support surface extenders configured to support limbs or the head of the patient, wherein the extenders are attachable to the frame via adjustable links.

[0029] In certain embodiments, the evacuation frame assembly further comprises multiple attachment points on each frame element configured to connect additional elements based on a rescuer’s requirements.

[0030] In certain embodiments, a method of rescuing and evacuating a patient using the evacuation frame assembly described above comprises unfolding the frame chain from a compact configuration; arranging the frame chain around the patient’s body; locking the opposing ends of the frame chain using the locking mechanism; adjusting the telescopic elements to fit as a frame around the patient’s body; and transporting the patient using the frame.

[0031] In some embodiments, transporting the patient comprises lifting the frame chain using one or more rings, handles, carrying straps or carrying poles.

[0032] In some embodiments, transporting the patient comprises attaching sliders or wheels to the frame and moving the frame and the patient using the sliders or wheels.

[0033] Operationally, the evacuation frame assembly can be assembled quickly and easily by following a few simple steps: the rescuer arranges the device around the victim’s torso, locks it in a single point, and adjusts it to size. Once assembled and in use, the device does not impair the view of the evacuation / rescue path and can allow one hand of the carrier to be free. It can also be used in a single or multiple-unit configuration.

[0034] The following is an illustration of an operation scenario: One rescuer arrives at a scene carrying a compactly folded evacuation frame assembly, e.g., in a backpack or hooked to a belt. Upon reaching the injured person, the rescuer unfolds the device and fits it around the patient’s body, e.g., between the armpits and the waist, locks the device around the patient and adjusts the device’s size to fit the patient, and extends a cargo net or support surface extender to support the patient’s head and / or legs. The rescuer uses a handle attached to the frame, or a carrying strap connected to the frame around his / her shoulder, to lift the patient and to carry the patient to a medical support tent or triage area for further treatment.

[0035] The following is an illustration of another operation scenario: Two rescuers arrive at a scene, carrying two or more compactly folded evacuation frame assemblies, e.g., in a backpack or hooked to a belt. Upon reaching the injured person, each unfolds the device and fits it around the patient’s body, one under the armpits and another around the waist, and each locks the device around the patient and adjusts the device’s size to fit the patient. Then, one rescuer extends a cargo net or support surface extender to support the patient’s head, while the other rescuer uses a similar extender to support the patient’s legs. One rescuer may use a carrying strap connected to the frame around his / her shoulder, while the other may use a handle attached to the frame to lift the patient. Alternatively, they may both use carrying poles connected to the frame. Together they lift the patient and carry the patient to a medical support tent or triage area for further treatment.

[0036] This process minimizes the time that the victim and the rescuers need to spend on an unsafe surface while supporting the rescuer’s safety and enabling the rescuers to function with one arm for another need. The result promotes the survivability of the injured while decreasing the risks to the rescuers.Brief Description of the Drawings

[0051] Referring now to the drawings, Fig. 1 is a schematic diagram showing an evacuation frame assembly 1 according to one embodiment of the invention. As shown in Fig. 1, the evacuation frame assembly 1 comprises an adjustable frame 5 having a plurality, e.g., two or more, rigid elements or rails 7,9,11,13, or elongated elements, that are connected to each other by hinges 17, forming a chain.

[0052] Adjustable frame 5 of evacuation frame assembly 1 is intended to be fit closely around the torso of a patient needing rescue. In certain embodiments, adjustable frame 5 comprises the fewest number of connected elements that can be arranged around the body of the patient, e.g., two or three. In certain other embodiments, adjustable frame 5 comprises as many connected elements that can be arranged so as to enable adjustable frame 5 to fit closely around the body of the patient, e.g., five, ten, or even more connected elements. In certain other embodiments, adjustable frame 5 comprises only as many connected elements that can be arranged so as to form a rectangular frame around the body of the patient, e.g., four.

[0053] In one embodiment, each of rails 7,9,11,13 in Fig. 1 has multiple subparts that are adjustable together, enabling the respective element to have a variable and adjustable length, so as to permit easy adaptation of frame 5 around the body of a patient. In this embodiment, rails 7,9,11,13 have a telescopic structure in which one rigid subpart slides alongside or into / out ofanother (in the directions of arrows A, B, C and D, respectively) to provide a variable length structure.

[0054] In certain embodiments, one or more of rails 7,9,11,13 may also have a length locking mechanism 15 that is configured lock the two or more subparts of each rail into position relative to each other. The locking mechanism can be a transverse locking pin, a clamping device or the like, or any other such locking mechanism as known in the art.

[0055] Rail 9 may comprise a body support or cushioning surface (not shown), at least on a surface facing the inside of closed adjustable frame 5. The body support surface can be formed from any material as known in the art, such as foam, padding, or the like, in order to provide comfort for the patient when adjustable frame 5 is arranged around the body of the patient. In some embodiments, the body support surface also has a locking mechanism that is configured to lock the body support surface in its position against or along the length of rail 9.

[0056] As discussed, rails 7,9,11,13 of adjustable frame 5 are connected to each other by hinges 17. The term “hinges” as used herein refers to any element that permits at least rotational connection between two parts. Hinges 17 can also be a flexure hinges, so as to permit slidable connection or some linear displacement of the connected elements in addition to rotational connection therebetween, as will be necessary when adjustable frame 5 is folded / unfolded, as discussed hereinbelow.

[0057] In certain embodiments, at least one of hinges 17 also has a locking mechanism (not shown) that is configured to lock hinge 17 into its respective position once the respective parts / subparts of adjustable frame 5 have been set relative to the other parts / subparts. In certain embodiments, each hinge 17 has such a locking mechanism. The locking mechanism can be a transverse locking pin, a clamping device, notches, or any other such locking mechanism as known in the art.

[0058] In some embodiments, the locking mechanisms of hinges 17 can lock the respective elements joined by hinges 17 into whatever angles are selected, once the elements of adjustable frame 5 are arranged around the body of the patient. Thus, in the embodiments in which adjustable frame 5 has four elements that are all straight or substantially straight, adjustable frame 5 will have a rectangular or square configuration once the locking mechanism of hinges 17 has locked the respective elements joined by hinges into approximately 90° angles. In other embodiments, the locking mechanism of hinges 17 can lock the respective elements joined by hinges into a varietyof angles, once the adjustable frame 5 is arranged around the body of the patient. In certain other embodiments, the variety of angles of hinges 17 may be any angles once the adjustable frame 5 is arranged around the body of the patient.

[0059] In certain embodiments, the two remote ends of the frame chain can be attached to each other using a locking mechanism 17a, such that the remote ends of adjustable frame 5 are arranged at a specific angle once so connected with locking mechanism 17a. In this embodiment, once the elements / subparts of adjustable frame 5 in an open position are arranged closely around the body of the patient, the remote elements of adjustable frame 5 are connected by locking mechanism 17a and set into a specific, pre-determined angle, and then the other elements of adjustable frame 5 are set into position by locking hinges 17 into whatever respective angles are selected, thereby arranging the parts into an operable configuration to form a rigid frame, as shown in Fig. 1.

[0060] While Fig. 1 shows a remote end of rail 11 being connected to a remote end of rail 7 by way of locking mechanism 17a and shows all other elements of adjustable frame 5 being connected by hinges 17, in another embodiment, any other two rails of adjustable frame 5 can be connected by locking mechanism 17a, with the rest being connected by hinges 17.

[0061] Because all rails are connected to each other in the form of a chain, when the evacuation frame is not being used, it can be folded into a stored configuration. Fig. 2 is a schematic illustration of the evacuation frame assembly 1 in a compactly folded configuration, illustrating the packed / stored structure. Fig. 2 demonstrates one of many folding options.

[0062] In this embodiment, at least one of hinges 17, and in certain embodiments only one of hinges 17, is separable and allows the two elements that are rotatably connected to each other to be completely disconnected. For example, the locking mechanism 17a that connects rail 11 to rail 7 can be separated, so as to allow rail 11 to be completely broken away from rail 7. Alternatively, any other of hinges 17 may be equally configured so as to be separable.

[0063] In the configuration as shown in Fig. 2, the hinges permit folding in a way that each rail lies against the others to enable maximum possible compactness. In one such configuration, hinges 17 allow the respective rails joined thereby to rotate from an angle that is virtually 0° to an angle that is virtually 360°. The folded frame can be carried naked or in a protected packaging (separated) compartment.

[0064] When needed, the folded evacuator frame assembly 1 can be quickly retrieved from its storage location and easily transported to the site of an injured patient. While in a compact stage, the device does not restrict the potential rescuer’s mobility or other operational needs, which is a distinct benefit when rescuers are traversing stairs, uneven terrain or significant heights. The device does not need to be unfolded before the rescuer reaches the patient, thereby not hampering the rescuer’s ability to reach the site.

[0065] Figs. 3 and 4 illustrate the successive stages transforming adjustable frame 5 from the folded configuration shown in Fig. 2 into the operable configuration shown in Figs. 1 and 5. When arriving on scene, the rescuer unfolds the apparatus frame 5 from the stored configuration shown in Fig. 2, by unfolding rails 7,9,1 1,13 into a completely open configuration, such as shown in Fig. 3, by unflexing hinges 17 between the connected rails 7,9,11,13 of adjustable frame 5. One end of the frame 5, shown here as rail 11 (although it can also be rail 7) is slid underneath the patient, as shown in Fig. 3, until it comes out on the other side of the patient’s body, as shown in Fig. 4. Then, the rescuer arranges the frame chain 5 around the patient’s body, and then brings the two remote ends together and locks them with the locking hinge 17a into the operable configuration around the patient’s body.

[0066] The locking hinge 17a is the main component that converts the chain into a frame. It must be strong enough to carry the weight and easy and fast to lock and release.

[0067] The rescuer then adjusts the adjustable frame rails 7,9,11,13 to the size of the patient's body or torso, using the telescopic nature of the rails, and locks the size of the frame using the length-locking mechanisms to lock the lengths of the rails (see Fig. 5). The telescopic structure of rails 7,9, 11,13 enables minimized carrying size and adjustability to the size of the patient's body, and the hinges 17 support compactness and adjustability to the specific patient.

[0068] The length locking mechanism 15, shown in Figs. 1 and 5, supports compactness and sizing, as the telescopic mechanism does. In one embodiment, each of rails 7,9,11,13 has a separate length lock, and each rail can be locked individually.

[0069] In another embodiment, the apparatus has one locking mechanism that, in one operation, is able to lock the size of multiple, even as many as all, rails at once. In one example, with reference to Fig. 4, a strap, string or wire is embedded within and runs through rails 7,9,11,13 and hinges 17, connected on one of its ends to one end 17a of the chain and connected on theother of its ends to the other end 17b of the chain. Pulling the strap, string or wire will adjust all the rails in the chain at the same time to closely fit frame 5 to the patient’s body size, after which the length of the strap, string or wire will be locked.

[0070] Because rescue of a patient from a burning house may require different rescue equipment than rescue from a snowy mountain slope, the ruins of collapsed buildings or a flooded area, the rescuer will need to adapt the use of the evacuation frame assembly 1 to the specific circumstances. As shown in Figs. 1 and 5, the evacuation frame assembly 1 may have accessories that enable it, once unfolded into the operable configuration, to be carried, e.g., by a rescuer, such as a handle 19 connected to one of rails 7,9,11,13. Alternatively, or in addition, evacuation frame assembly 1 may be equipped with connection or attachment points on one of rails 7,9,11,13 to which external devices may be connected or attached temporarily so as to adapt the evacuation frame assembly 1 to the type of rescue required, such as rings 18, to which adjustable carrying straps, as will be discussed hereinbelow, or elongated carrying rods may be attached for use during transport of the patient. Rings 18 may themselves also be used in place of handle 19 for carrying frame 5 by hand. Rings 18 and / or handle 19 may be fixedly mounted to one of rails 7,9,11,13, e.g., the top, bottom or side rails, or they may be attached thereto via a hinge that allows handle 19 to be rotated and stored when frame 5 is in the compactly folded configuration shown in Fig. 2.

[0071] Figs. 6A and 6B show embodiments with one or more support rails or stabilizers 24,25 that, in the embodiments shown, are attached to the lowermost of rails 7,9,11,13 and function to support the patient’s back and help the patient to be carried using the evacuation frame assembly 1. In another embodiment, the support rails or stabilizers 24,25 may be used to support other parts of the patient’s body or other objects, either along with or separate from the patient. Fig. 6A shows embodiments using two frames, and Fig. 6B shows embodiments using one frame.

[0072] Fig. 6B shows frame 5 with one or more support stabilizers 25, which may be attached to the lowermost rail 9 of adjustable frame 5 by any means known in the art, e.g., via a support rail / stabilizer axis 26. As shown in Fig. 6B, support stabilizer 25 may be attached below rail 9 even when frame 5 is in a compact folded configuration, or support stabilizer 25 may be separate and attached to rail 9 once frame 5 is opened into the operable configuration, e.g., immediatelybefore use. Support rail or stabilizer 25 could be foldable or telescopic to allow its length to be variable, and may also be lockable to allow the variable length to be set.

[0073] Fig. 6A shows dual-frame embodiments, in which a support rail / stabilizer 24 is attached between the lower rails 9 of two separate adjustable frames 5. In the top image, support 24 is shown as telescopic (and lockable) , although it could be foldable, and in the bottom image, support rail / stabilizer 24 has a set length. Support rail / stabilizer 24 stabilizer may be attached to rail 9 of adjustable frame 5 by any means known in the art.

[0074] While Figs. 6 A and 6B show support rail / stabilizer 24 as a narrow rail, support rail / stabilizer 24 can be as wide as necessary and practicable using frame 5.

[0075] In certain embodiments, one or more support rails or stabilizers 24,25 function to support the patient’s back and allow the patient to be carried between using the two separate frames 5 of the evacuation frame assembly 1. In another embodiment, support rails or stabilizers 24,25 may be used to support other parts of the patient’s body or other objects, either along with or separate from the patient, or may be used to stabilize the connection between the two frames 5.

[0076] Alternatively, or in addition, support rails or stabilizers 24,25 may be attached to others of rails 7,9,11,13 of frame 5, in the form of a side or top support rail / stabilizer 24a, which is attached to a side or the top of frame 5 in Fig. 8A. For example, a back injury may require connecting stabilizers to the sides (24a) of the patient’s body.

[0077] In operation of an embodiment using support rail / stabilizer 24 or 25 (Figs. 6A and 6B), the rescuer may tilt the patient sideways and position support rail / stabilizer 24,25 centrally under the patient, then may extend support rail / stabilizer 24,25 lengthwise as necessary in order to support the patient.

[0078] Once frame 5 supports a patient, handle 19 (as shown in Fig. 6B) or rings 18 for attachment to adjustable carrying straps 23 (as shown in Fig. 6C) or to elongated carrying poles may enable frame 5 to be carried by one or more rescuers. Alternatively, two or more rescuers can use elongated carrying poles that are threaded through rings 18. Once the patient is supported on support rail / stabilizer 24,25 and is ready to be carried, the rescuer or rescuers lift the patient using the handle 19, carrying straps 23 or elongated carrying poles, or any combination thereof.

[0079] As shown in Fig. 6D, some embodiments of the evacuation frame assembly 1, particularly a dual -frame configuration, may include support surface extenders 21 to support loose body parts, such as the head and limbs. These extenders may include an extendable platform 21, such as a cargo net or other similar lightweight but sturdy material, supported by adjustable straps or links 20 that extend to the frame 5. Support surface extenders 21 may have pockets to allow placement of the patient’s head or feet, so that they don’t dangle and get hurt during transport and / or hamper the rescuer’s transport of the patient.

[0080] Figs. 7A-7C shows use of the evacuation frame assembly to carry a patient. The evacuation frame assembly is configured to function as a single frame device (Fig. 7C). However, it is better for the patient and the rescuer to use a multi-frame device (Figs. 7A and 7B).

[0081] Fig. 7A shows use of a dual-frame embodiment of the evacuation frame assembly to carry a patient, using a handle 19 and a carrying strap 23. If support rail / stabilizer 24 that supports the patient’s back is used, the two frames 5 are attached thereby. If no support rail / stabilizer 24 is used, the two frames 5 are not attached.

[0082] Fig. 7B shows use of a dual-frame embodiment of the evacuation frame assembly to carry a patient, using support surface extenders 21 that extend outward from frame 5. The rescuer may extend the support surface extenders 21 under the loose body parts and lift the patient, using a handle 19 or a carrying strap 23.

[0083] The device’s operation, i.e., unfolding, deployment and use, as described, is fast and intended to minimize the time spent in an unsafe location. The rescuer may carry the evacuation frame assembly 1 using handles or straps, or may hang the device on his / her body like a necklace, during use. As the evacuation frame assembly is assembled tightly against the patient’s body, it limits the obstruction of visibility to the minimum possible, which enables the carrier to watch the area in front and increase the carrier’s safety while navigating the path to the target location.

[0084] Depending on the rescuer's strength, the apparatus supports the rescuer's ability to free one hand for other functions.

[0085] The evacuation frame assembly 1 may be equipped with additional connection or attachment points for external features that can be connected or attached temporarily to adapt the device to the type of rescue required, such as in one or more elements 7,9,11,13 of frame 5, e.g., one or more holes 28a for threading, a slot for sliding, a hook for hanging, a loop for a lock, and others, as shown in Fig. 8A.

[0086] For example, as shown in Fig. 8A, evacuation frame assembly 1 may be fitted with one or more sliders 27, which may be elongated platforms, like a ski or a snowboard, that are attached to the frame's bottom rail 9,9A, such as by screws or rods 28 through holes / tubes 28a, or any other means known in the art. Slider 27 does not need to be longer than the distance between the two frames 5.
