The present disclosure relates to apparatuses, devices, systems, and methods for lifting a person, animal, or patient. More specifically, the present disclosure relates to apparatuses, devices, systems, and methods for use when patients are in tight, close, or cramped conditions and would like a lift assist.
People or animals can experience falls in a variety of conditions and at any time of the day. Depending on the condition of the person or animal and nature of the fall, after a fall, a person or animal may be unable to move to a standing, prone, supine, kneeling, or sitting position, move from their position after the fall, seek help or medical care. This may be due to the physical condition or abilities of the person or animal, injuries received as a result of the fall, the person or animal becoming wedged or stuck between structures or fixtures, and/or for various other reasons. In such a condition, the person or animal may desire assistance to free themselves situation and/or to move from a position after the fall to a different position, such as a standing, seated, or other position. Such persons or animals are referred to herein as patients. Alternatively, or in addition, patients may intentionally take a position on a floor or ground without experiencing a fall, but then learn that they require assistance to move from the position on the floor or ground to a different position.
Various devices, apparatuses, and systems have been developed to assist patients who have experienced a fall to move from a fallen position to a desired new position. Unfortunately, these devices are inadequate to assist patients who are in a fallen position in very small, tight, or confined conditions. Advantageously, the present disclosure includes an apparatus, device, system, and/or method that overcomes this inadequacy.
The various apparatuses, devices, systems and methods of the present disclosure have been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available lift apparatuses, devices, systems, and methods.

Standard medical planes of reference and descriptive terminology may be employed in this disclosure. While these terms are commonly used to refer to the human body, certain terms are applicable to physical objects in general. A standard system of three mutually perpendicular reference planes is employed. A sagittal plane divides a body into right and left portions. A coronal plane divides a body into anterior and posterior portions. A transverse plane divides a body into superior and inferior portions. A mid-sagittal, mid-coronal, or mid-transverse plane divides a body into equal portions, which may be bilaterally symmetric. The intersection of the sagittal and coronal planes defines a superior-inferior or cephalad-caudal axis. The intersection of the sagittal and transverse planes defines an anterior-posterior axis. The intersection of the coronal and transverse planes defines a medial-lateral axis. The superior-inferior or cephalad-caudal axis, the anterior-posterior axis, and the medial-lateral axis are mutually perpendicular.
Anterior means toward the front of a body. Posterior means toward the back of a body. Superior or cephalad means toward the head. Inferior or caudal means toward the feet or tail. Medial means toward the midline of a body, particularly toward a plane of bilateral symmetry of the body. Lateral means away from the midline of a body or away from a plane of bilateral symmetry of the body. Axial means toward a central axis of a body. Abaxial means away from a central axis of a body. Ipsilateral means on the same side of the body. Contralateral means on the opposite side of the body from the side which has a particular condition or structure. Proximal means toward the trunk of the body. Proximal may also mean toward a user, viewer, or operator. Distal means away from the trunk. Distal may also mean away from a user, viewer, or operator. Dorsal means toward the top of the foot or other body structure. Plantar means toward the sole of the foot or toward the bottom of the body structure.
Antegrade means forward moving from a proximal location/position to a distal location/position or moving in a forward direction. Retrograde means backward moving from a distal location/position to a proximal location/position or moving in a backwards direction. Sagittal refers to a midline of a patient's anatomy, which divides the body into left or right halves. The sagittal plane may be in the center of the body, splitting it into two halves. Prone means a body of a person lying face down. Supine means a body of a person lying face up.

In one embodiment, a shaped opening may have one shape when a structure that includes the shaped opening is in a first configuration and a second shape, different from the one shape, when the shaped opening is in a second configuration. For example, where a shaped opening is in a sheet, when the sheet is unfolded and laid out flat, the shaped opening may have a first shape (e.g., a circle or oval) and when the sheet is in use or not laid out the form of the shaped opening may change because of the pliable nature of the sheet.
As used herein, “edge” refers to a structure, boundary, or line where an object, surface, or area begins or ends. An edge can also refer to a boundary or perimeter between two structures, objects, or surfaces. An edge can also refer to a narrow part adjacent to a border. (search “edge” on Merriam-Webster.com. Merriam-Webster, 2021. Web. 3 Aug. 2021. Modified.) In certain embodiments, an edge can be a one dimensional or a two dimensional structure that joins two adjacent structures or surfaces. Furthermore, an edge may be at a perimeter of an object or within a perimeter or boundary of an object.
“Closure” refers to any device, system, method, or apparatus to facilitate temporary and repeatable opening and closing.

The present disclosure discloses an apparatus, device, system, and/or method for lifting a patient. Conventional devices and methods can be unworkable when a patient is on a floor in a confined space. Alternatively, or in addition, ingress and/or egress of a building from where the patient is on the floor can be constricted and limited due to narrow doorways, halls, entries, and the like. Such confined spaced render conventional backboards, stretchers, and/or gurneys ineffective or impractical. What is needed is an apparatus, device, system, and/or method that can effectively be used to lift a patient from a floor in a confined tight space. The present disclosure provides one example for use in such situations.
In the scenario 100, a patient 110 may be seated on the floor 108 between the bed 104 and wall 106c. The patient 110 may have fallen to the position 112 illustrated in
In
When a patient 110 finds themselves in position 112, the patient 110 may first attempt to move out of the position and/or to sit up, kneel, and or stand up. However, the condition of the patient 110 and/or objects surrounding the patient 110 may prevent them from standing, sitting, kneeling, getting on the bed 104 or moving from position 112. For example, the patient 110 may have been injured in a fall to the floor 108 to position 112. Alternatively, or in addition, the patient 110 may suffer from certain physical conditions that limit their mobility or ability to move or sit up or stand from position 112. For example, the patient 110 may be missing a extremity, a hand, a foot, may have excessive weight, may be experiencing pain, may have weak or incapable hip, leg, or foot joints, may be wedged between the bed 104 and the wall 106c (for example), may be unconscious, or may have some other condition that prevents or limits their ability to move from position 112 and/or sit or stand. Those of skill in the art will appreciate the patient 110 may have a variety of conditions that limited or prevent the patient 110 from moving from, standing from, or leaving position 112.
When the patient 110 recognizes that they cannot move from position 112 without help or assistance, they may call for help or assistance. Or, assistance may be called or sent. A patient or another may request lift assistance or a lift operation. In certain situations, the patient 110 may request assistance from another person such as a family member, friend, neighbor, or stranger. This other person may also be unable to help the patient 110 move from the position 112. And/or the other person alone may not have sufficient skills or strength to assist the patient 110 is moving from the position 112 or standing. Alternatively, or in addition, the patient 110 or another person may request assistance from emergency personnel, first responders, paramedics, and/or emergency medical technicians (EMTs).
When the other person, persons, or emergency personnel arrive, they may assess the situation to determine how best to help the patient 110. Emergency responders may have limited space to work in to provide a lift assist. Furthermore, people who are prone to falls and not capable of standing themselves up or getting out of a tight space may have physical or medical conditions that inhibit or prevent them from standing on their own or moving out of the tight space. Often, a patient 110 stuck with their behind or hip on the floor. A patient 110 may not be able to lift the part of their body contacting the floor. This may be due to a weight of the patient 110, weak muscles of the patient 110, and/or a medical/health condition of the patient 110. Maneuvering a flexible lift device under the patient can be difficult, impractical, and/or impossible.
In certain scenarios, those assisting may not be able to, or may choose not to, pull the patient 110 using their arms or legs to prevent injuring or further injuring or causing pain to the patient 110. EMS personnel or other first responders may be trained to normally position a patient 110 such that the patient 110 can be rolled onto a tarp, stretcher or the like. However, the scenario 100 makes such a procedure for rolling a patient or otherwise getting a tarp or sheet under the patient too challenging or impractical. Advantageously, one or more embodiments of the present disclosure can be used to perform a lift operation on the patient 110. In particular, the present embodiments of the present disclosure can be used to perform a lift operation on the patient 110 without rolling the patient or moving the patient prior to the lift operation.
The sheet 210 serves as a main body or structure for the lift device 200. The sheet 210 can be pliable and/or flexible. The sheet 210 can be of any size. In certain embodiments, the sheet 210 is large enough to surround a patient 110 before or during a lift operation. For example, the sheet 210 can have a length of between about 5-7 feet and a width of between about 3-4 feet. In certain embodiments, the sheet 210 is larger than the height and/or width of the patient 110 or a set of potential patients. Generally, if the sheet 210 is larger than the patient 110 this is not a problem and does not interfere with the lift operation.
The sheet 210 can be of a variety of shapes and sizes. For example, the sheet 210 may be a rectangle, square, triangle, or other polygon. Similarly, the sheet 210 can be round, circular, oval. Alternatively, or in addition, the sheet 210 can include both straight and/or curved edges. In the illustrated embodiment, the sheet 210 includes a top edge 212, a bottom edge 214, a left edge 216, and a right edge 218.
The sheet 210 is durable and may be reinforced across one or more surfaces of the sheet 210 and/or edges of the sheet 210. A sheet 210 can be made of a variety of materials including, but not limited to, cloth, fabric, polyester, canvas, leather, nylon, polyethylene, polypropylene. The sheet 210 can be of one layer or multiple layers. The material of a sheet 210 can be a single material or a weave or braid of threads, tethers, or straps of a single material or a combination of materials. Examples, of sheets include, but not limited to, tarps, blankets, covers, and the like. A sheet 210 can be water-proof, water-resistant, stain-resistant, fire-proof, fire-resistant, or the like depending on the composition, structure, configuration, and/or material of the sheet.
In certain embodiments, the lift device 200 and/or sheet 210 includes an opening 240. In one embodiment, the opening 240 extends from an edge of the sheet 210. In the illustrated embodiment, the opening 240 extends from the bottom edge 214. An opening 240 that extends from an edge of the sheet 210 facilitates positioning the sheet 210 around a patient 110 prior to, during, or as part of, a lift operation. One goal of a lift operation may be to get the patient 110 onto the sheet 210 while requiring minimal movement or effort from the patient 110. An opening 240 that extends from an edge of the sheet 210 facilitates accomplishing this goal.
Often, the need for the lift operation is due to the patient 110 having sever immobility such that the patient may not be able to even lift, raise, roll, or move one or more of their body parts off of the floor. With an opening 240 that extends from an edge of the sheet 210, the patient 110 does not need to raise the body part off the floor for the lift operation using the lift device 200 to be successful.
The length, size, shape, and configuration of the opening 240 can vary in different embodiments. In the illustrated embodiment, the opening 240 extends from the bottom edge 214 to approximately the midpoint of the top edge 212. Having the opening 240 extend to or near a midpoint can be advantageous because this can facilitate positioning a patient 110 at, or near, a center of the sheet 210 such that the patient 110 remains within, or on a surface of, the sheet 210 during a lift operation. One goal of the lift operation may be to not drop the patient 110 and another goal may be to not further injure or frighten the patient 110. Having the patient 110 centered within or upon the sheet 210 can help in meeting one or more of these goals by keeping the patient 110 stable during the lift operation.
In the illustrated embodiment, the opening 240 includes a slit 242 that extends from an edge of the sheet 210 and a shaped opening 244. In one embodiment, the opening 240 can include only the slit 242. In one embodiment, the opening 240 can include only the shaped opening 244. In another embodiment, the opening 240 can include a slit 242 and at least a shaped opening 244.
In the illustrated embodiment, the slit 242 is connected to the shaped opening 244 and the slit 242 extends from the bottom edge 214. Of course, those of skill in the art will appreciate that the opening 240 can include only a slit 242. Alternatively, or in addition, the opening 240 can extend from any edge of the sheet 210. In certain embodiments, the shaped opening 244 can serve as a relief for the slit 242 such that stresses or strains on the slit 242, edges of the slit, and/or sheet 210 can be managed and the opening 240 is not damaged during one or more lift operations.
In another embodiment, the lift device 200 and/or sheet 210 includes an opening 240 and a shaped opening 244. The shaped opening 244 can be within a perimeter of the sheet 210. The shaped opening 244 can be connected to the opening 240.
In the illustrated embodiment, the shaped opening 244 is positioned approximately to include a midpoint of the sheet 210. The shaped opening 244 can be within a perimeter of the sheet 210. In the illustrated embodiment, the shaped opening 244 is approximately centered with respect to the top edge 212, bottom edge 214, left edge 216, and right edge 218. Having the shaped opening 244 centered can help provide a secure and stable lift for the patient 110.
The slit 242 can have various configurations. In one embodiment, the slit 242 is straight. In another embodiment, the slit 242 can be curved. In yet another embodiment, the slit 242 can have a zig-zag shape.
In the illustrated embodiment, the shaped opening 244 is in the shape of a circle. Of course, the shaped opening 244 can have a variety of shapes, including but not limited to, oval, square, triangle, rectangle, another polygon, or the like. The opening 240 serves to facilitate positioning the sheet 210 around one or more body parts of a patient 110 that are resting on a floor or ground. Similarly, the shaped opening 244 can also serve to facilitate positioning the sheet 210 around one or more body parts of a patient 110 that are resting on a floor or ground.
The size and shape of the shaped opening 244 can be defined to comfortably circumscribe a body part (e.g., buttocks, thigh(s), legs, torso, back, etc.) of a patient 110 that is contact with a surface of a floor or ground. In one embodiment, the shaped opening 244 has a diameter of between about 6 inches and about 12 inches. The shaped opening 244 can have a diameter smaller than about 6 inches and/or can have a diameter larger than about 12 inches. In certain embodiments, the shaped opening 244 includes a diameter greater than an area of contact of one or more body parts of a patient 110 and a floor or ground. The shaped opening 244 can include one or more edges and the edges may be reinforced with stitching, straps, other fabric, a seam, or the like.
The closure 270 serves to close, at least partially, one or more portions, edges, or parts of the opening 240. In certain embodiments, the closure 270 can completely close the opening 240. Closing the opening 240 about the patient 110 facilitates placement of the patient 110 on the sheet 210 for a lift operation.
Activation of the closure 270 may at least partially close the opening 240. Deactivation of the closure 270 may at least partially open the opening 240. Advantageously, the closure 270 is configured to be selectively opened/activated and/or selectively closed/deactivated. In certain embodiments, the closure 270 can be configured to close both a slit 242 and a shaped opening 244, just the shaped opening 244, and/or just the slit 242. Advantageously, the closure 270 is configured to open or close the opening 240. In this manner, the opening 240 can be opened for initial stages of a lift operation and closed for subsequent stages of the lift operation.
In one embodiment, the present disclosure includes a lift system for lifting a patient. The lift system may include a sheet, such as sheet 210 having a first edge, such as top edge 212, a second edge opposite the first edge, such as bottom edge 214. The first edge and second edge can be parallel. The sheet 210 can also include a third edge, such as left edge 216 and a fourth edge, such as right edge 218 that is opposite and parallel to the third edge. The lift system can also include a shaped opening, such as shaped opening 244 within a perimeter of the sheet, such as sheet 210. The lift system can also include a slit, such as for example slit 242 that extends from the fourth edge and connects to the shaped opening. The lift system can also include a closure, such as for example closure 270 that at least partially closes the shaped opening and/or the slit when the closure is activated. It should be noted that in certain embodiments the closure may at least partially close a shaped opening and a the slit.
In the illustrated embodiment, the closure 270 includes one or more, or a plurality of fasteners 272. One or more of the fasteners 272 can be configured to extend across the opening 240. In the illustrated embodiment, the fasteners 272 are configured to extend across the slit 242. In certain embodiments, one or more fasteners 272 or other structure can extend across a shaped opening 244.
Those of skill in the art will appreciate that the fasteners 272 of the illustrated embodiment are but examples of a variety of types of one or more fasteners 272 that can be used in different embodiments of lift device 200. Examples of such alternative fasteners 272 include, but are not limited to, snaps, eyelets and laces or a tether that can cross the slit 242, Velcro® (hook and loop fasteners), zippers, and the like, or a combination of these. Those of skill in the art will also appreciate that features of one member of a fastener 272 can be implemented on one side of the fastener, on the other side of the fastener, or on both sides of the fastener.
Alternatively, or in addition, the fasteners 272 of a closure 270 can be of the same type and similar in length, functionality and configuration. Or, the fasteners 272 of a closure 270 can vary in type, length, functionality and configuration. All such combinations and/or permutations are within the scope of the present disclosure.
In one embodiment, the fasteners 272 are reusable such that the fasteners 272 can be repeatedly opened (unfastened) and closed (fastened). In certain embodiments, the fasteners 272 are adjustable such that one or more fasteners 272 can be adjusted from a first length to a second length. The first length can be longer than the second length and/or the first length can be shorter than the second length.
In the illustrated embodiment, a fasteners 272 can include a first member 274, and a second member 276. The first member 274 and/or the second member 276 can be configured to releasably engage each other. For example, the second member 276 can be configured releasably engage the first member 274.
In the illustrated embodiment, the first member 274 may be a buckle or a part of a buckle and the second member 276 may a buckle or may be a corresponding part of the buckle. For example, the first member 274 may be a male side squeeze buckle and the second member 276 may be a female side squeeze buckle, or vice versa. The first member 274 can releasably engage with the second member 276.
In one embodiment, the fasteners 272 includes a first strap 278 connected or coupled to the first member 274 and a second strap 280 connected or couple to the second member 276. In certain embodiments, one or the other or both of the first strap 278 and the second strap 280 can be adjustably coupled or connected to one of the first member 274 and the second member 276.
In the illustrated embodiment, the first strap 278 is adjustably connected or coupled to the first member 274. The first strap 278 can include an end 282 that extends from the first member 274 when the first strap 278 engages the first member 274. Advantageously, a user can adjust a length of the first strap 278 used for the closure 270 by sliding the first strap 278 through the first member 274 such that the end 282 is closer to the first member 274. In this manner, the user can increase the length of the first strap 278 for the closure 270. Similarly, a user can adjust a length of the first strap 278 used for the closure 270 by sliding the first strap 278 through the first member 274 such that the end 282 is further away from the first member 274. In this manner, the user can decrease the length of the first strap 278 for the closure 270.
A closure 270 with one or more adjustable length fasteners 272 can facilitate activation of the closure 270 during a lift operation. For example, one or more adjustable length fasteners 272 can be extended to their maximum lengths, and/or one side of a fastener can be disconnected from a corresponding side to facilitate positioning the sheet 210 around one or more body parts of a patient 110 during a lift operation. Next, one or more buckles or members of the one or more fasteners can be connected or engaged, while adjustable length fasteners 272 are at extended lengths. Next, a user can activate the closure 270 can close off an opening 240 by adjusting the fasteners 272 to a shorter length. In certain embodiments, adjusting the adjustable length fasteners 272 can draw the slit 242 and/or a shaped opening 244 partially or completely closed for a next stage of a lift operation.
In another embodiment, a fastener 272 a can include a first member 274 and a second member 276 configured to releasably engage the first member 274. For example, in one embodiment the first member 274 can be a strap secured to the sheet 210 and the second member 276 can be a cam buckle (not shown). A cam buckle is a type of buckle configured to accept an end, such as end 282 of a strap such as first strap 278 that is threaded through the cam buckle. The cam buckle includes a biased clamp or set of teeth that engage the first strap 278. The biased clamp can be disengaged/released such that the cam buckle can be threaded further along a length of the first strap 278 and then the biased clamp can be engaged/unreleased to engage the first strap 278 an restrain the first strap 278 from reverse threading relative to the cam buckle. A fastener 272 that includes a strap and a cam buckle can also provide an adjustable fastener for the closure 270.
In the illustrated embodiment of
In the illustrated embodiment, the shaped opening closure 374 includes one or more shaped opening fasteners 376. The shaped opening fasteners 376 may traverse or may be configured to traverse the shaped opening 344 before, or as, the shaped opening closure 374 is activated. In the illustrated embodiment, the shaped opening closure 374 includes a plurality of shaped opening fasteners 376 that traverse or are configured to traverse the shaped opening 344. In one embodiment, the shaped opening closure 374 can include at least one strap 378.
In one embodiment, each shaped opening fastener 386 can include a strap 378 connected at a first end 380 to one side 382 of the shaped opening 344 and connected at a second end 384 to an opposite side 386 of the shaped opening 344. In one embodiment, the first end 380 is connected to a first edge 388 of the shaped opening 344 and the second end 384 is connected to a second edge 390 approximately opposite the first edge 388. Alternatively, or in addition, the first end 380 and/or the second end 384 may not be connected to an edge of the shaped opening 344, instead the first end 380 and/or second end 384 can be connected to one or more handles 392.
The strap 378 may be flexible or pliable such that distortion of the shape of the shaped opening 344 can move the strap 378 to one side of the shaped opening 344, particularly when a slit 342, connected to the shaped opening 344, is enlarged. The straps 378 can be moved to one side by a user deploying the lift device 300.
Conversely, as the shaped opening 344 is distorted to bring sides of the shaped opening 344 closer to each other (and/or the first opening edge 346 is brought closer to the second opening edge 348), the strap 378 slides towards a center of the shaped opening 344 to provide at least partial closure of the shaped opening 344. As multiple straps 378 slide towards a center of the shaped opening 344 the shaped opening 344 is closed off.
In the illustrated embodiment, the shaped opening fastener 376 includes a plurality of straps 378. The straps 378 may be independent of each other and connect opposite sides of the shaped opening 344. Alternatively, or in addition, the straps 378 may be associated with each other to facilitate closing the shaped opening 344. For example, the straps 378 can be interwoven with each other to facilitate closing the shaped opening 344. Alternatively, or in addition, the straps 378 may be connected to each other where they overlap, such as with stitches.
In the illustrated embodiment, the sheet 310 can include three or more edges (e.g., top edge 312, bottom edge 314, left edge 316, and right edge 318). One or more of the straps 378 may be coupled to a handle 392 (e.g., handle 392a, handle 392b, handle 392c, handle 392d) near an edge of the sheet 310, in particular near an edge that does not include the opening 340. (e.g., left edge 316 and right edge 318). Alternatively, or in addition, the straps 378 can be connected to the sheet 310, for example by stitches. The straps 378 can form the handles 398. In addition, the lift device 300 can include a plurality of handles 398 around the edges. The handles 398 can provide a strategic and/or convenient location for a user, such as an emergency responder, to hold the sheet 310 during a lift operation.
In one embodiment, use of the lift device 300 can activate one or more closures 360/374. For example, one user pulling on handle 392a and handle 392b and another user pulling on handle 392c and handle 392d can put tension force in one or more straps 378 connected to the handles 392. This tension force can cause multiple straps 378 to move towards a center of the shaped opening 344 which closes off the shaped opening 344. In this manner, use of the lift device 300 can activate one or more closures of the lift device 300.
During a lift operation, the shaped opening 344 may experience high stress and strain. Therefore, in certain embodiments, an edge of the shaped opening 344, such as first edge 388 and/or second edge 390 can include a reinforcement member 396. The reinforcement member 396 adds strength and durability to the edge to mitigate damage or failure. A variety of structures can serve as the reinforcement member 396. In one embodiment, the reinforcement member 396 is reinforcement stitching. In another embodiment, the reinforcement member 396 is a strap sewn around the edge.
Alternatively, or in addition, a user can engage one or more fasteners 362 of a slit closure 394 (See
Ideally, each of the fasteners 362 is engaged to fully close the slit 342. Alternatively, or in addition, one or more fasteners 362 closest to a midpoint of the sheet 310 can be engaged and the lift device 300 can still be effectively used to lift a patient 110 even though all fasteners 362 may not have been engaged. Since less weight of a patient 110 is, or will be, near the fasteners 362 closest to the bottom edge 314, engagement of the fasteners 362 closest to the bottom edge 314 may not be essential for an effective lift operation.
Accordingly, the lift device 400 may include a sheet 410, opening 440, and at least one closure 460. One difference between the lift device 400 and the lift device 200 or lift device 300 may be in the use and kind of closure 460 and/or shaped opening closure 474. In the illustrated embodiment, the closure 460 and/or shaped opening closure 474 includes one or more biasing members 420.
The biasing members 420 may serve as part of a closure 460 and/or part of a shaped opening closure 474. The biasing members 420 facilitate closing the opening 440, such as the slit 442 and/or the shaped opening 444. In the illustrated embodiment, the biasing members 420 can extend across the shaped opening 444 and aid in narrowing or closing the shaped opening 444 and/or the slit 442.
In one embodiment, the biasing members 420 is embodied as a shaped opening fastener 476. The biasing members 420 can be an elastic band, elastic member, and/or elastic strap. The biasing members 420 can include a first end 422 and a second end 424. The first end 422 can connect to the sheet 410. The second end 424 can connect to one of an edge 426 of the shaped opening 444 or an edge 426 of the slit 442. Alternatively, the second end 424 can connect to edge 426 of both the shaped opening 444 and the slit 442. In one embodiment, the edge 426 of shaped opening 444 and/or the slit 442 is opposite where the biasing member 420 connects or is connectable to the sheet 410.
In one embodiment, the biasing member 420 is configured to apply a closure force on the one edge 426 of the shaped opening 444 or the slit 442 in response to the one edge 426 of the shaped opening 444 or the slit 442 being moved away from another edge of one of the shaped opening 444 and/or the slit 442. In one example, the biasing members 420 can be activated, or create the closure force, by a user widening or opening up the opening 440, such as by widening the slit 442. Once the opening 440 is widened the closure force can act to encourage closure of the opening 440. This action is automatic and can assist a user in positioning and arranging the sheet 410 around a patient 110 for a lift operation.
In certain embodiments, the fasteners 462 can include one or more markings (not shown) to assist users in activating the closure 460 for a lift operation. The markings may be used to ensure that one first member 464 is properly coupled to a corresponding second member 466 of a fastener 462. For example, the first member 464 or second member 466 can be marked with an alphanumeric symbol and the other of the first member 464 or second member 466 can be marked with another corresponding alphanumeric symbol (e.g., “1” may be marked on both a first member 464 and a second member 466). Or, a geometric symbol or shape can be marked on both a first member 464 and a second member 466. Or, a color can be marked on both a first member 464 and a second member 466. A user can be trained to look for the corresponding markings on the first member 464 and the second member 466 and match these up to operate or activate the closure 460. In certain embodiments, the markings facilitate activation of the closure 460 and/or the slit closure 494.
Alternatively, or in addition, the markings can serve to ensure that coupling of certain fasteners 462 have, or are given, priority over coupling of other fasteners 462. For example, fasteners 462 closer to the center of the sheet 410 may be color coded to encourage coupling of these fasteners first or before a lift operation is attempted. For example, fastener 462a may be color coded “red” to indicate that this fastener 462a should be coupled before attempting a lift operation. Fastener 462b may be color coded “yellow” to indicate that coupling this fastener 462a is advisable before attempting a lift operation. Fasteners 462c and 462d may be color coded “green” to indicate that coupling these fasteners 462c and 462d is advisable, but optional, before attempting a lift operation.
Those of skill in the art will appreciate that the examples of alphanumeric symbols, geometric symbols, and/or colors are but a few of a number of other types and/or kinds of markings that can be used to facilitate operation of fasteners 462. The present disclosure is not limited to these examples. The present disclosure includes other markings within the scope of the claims.
In the illustrated embodiment, the lift device 400 includes one or more reinforcement members 496. The one or more reinforcement members 496 can extend across at least a portion of the sheet 410. The one or more reinforcement member 496 provide added strength, stability, and durability to the lift device 400/sheet 410. A variety of implementations for the reinforcement member 496 can be used including added layers to the sheet 410.
In the illustrated embodiment, the reinforcement member 496 includes a strap that extends from one edge to an opposite edge (e.g., top edge 412 to bottom edge 414, or left edge 416 to right edge 418). Alternatively, or in addition, a reinforcement member 496 may be connected to an edge around the sheet 410. The reinforcement member 496 can be secured to the sheet 410 using a variety of techniques and/or technologies including heat welding, glues, stitching, and the like. In
In certain embodiments, the handles 492 can be coupled to, or engage with, one or more reinforcement members 496.
Referring now to
As another example, a marking 498b may identify which side of the sheet 410 is intended to be facing and contacting the patient 110. Having a particular side of the sheet 410 facing the patient 110 can be advantageous because one side may be smoother and have a more comfortable surface than the other side.
The lift device 500 includes a first panel 502 having a first edge 504, a second panel 506 having a second edge 508, and a closure 560. The first panel 502 can include a top edge 512, a bottom edge 514, and a left edge 516 in addition to the first edge 504. In one embodiment, the first edge 504 extends from the top edge 512 to the bottom edge 514. Similarly, the second panel 506 can include a top edge 512, a bottom edge 514, and a right edge 518 in addition to the second edge 508. In one embodiment, the second edge 508 extends from the top edge 512 to the bottom edge 514.
