This application is in the field of medical repositioning devices.
In medical environments, such as hospital intensive care units, caregivers and medical staffers may devote a significant portion of their time to moving and repositioning patients that are not capable of moving themselves. For example, to inhibit formation of pressure ulcers or bed sores in patients that are comatose or otherwise incapable of moving on their own accord, medical caregivers may be tasked with moving and/or repositioning these patients at regular intervals (e.g. every two hours). Moreover, some patients are not capable of moving by themselves, and caregivers may be asked to help move such patients from one location to another, for example, from a hospital bed to the toilet, and back again. This movement and repositioning can be a strenuous and even dangerous practice for the caregivers, particularly where the patient is heavy relative to the strength of the caregiver.
To help caregivers reposition patients, medical facilities may utilize repositioning sheets, such as the Comfort Glide™ repositioning sheet sold by Medline Industries. These repositioning sheets provide a soft upper surface that is comfortable for a patient to rest upon, a lower friction surface on an underside of the sheet, and handles that help the caregivers grasp the sheet. These features help the caregivers to slide the sheet and patient along a resting structure, such as a hospital bed, which makes the process of repositioning less burdensome for the caregiver.
Another technique that medical facilities employ to move or reposition a patent involves using a sling with a patient lift. Such slings can be placed underneath a patient, and strapped or otherwise engaged with a lifting device that uses a hoist to lift a patient off a resting structure, after which the patient can be moved, repositioned, or transferred to another resting structure.
While both the repositioning sheet and the lift/sling systems can be effective tools for moving patients, in certain situations one tool may be more effective than the other. For instance, where multiple caregivers (e.g., nurses) are present at a patient's side, and that patient is to be moved only a short distance, (e.g., from a supine to a partially recumbent resting position on a hospital bed), the repositioning sheet can provide a quick and efficient technique to achieve the movement that does not need to involve the use of the large lifting equipment. However, where the patient requires movement over a greater distance (e.g., transfer from a hospital bed to a wheelchair or an operating table), the sling/lift may be a more effective tool.
The present application describes tools and techniques that allow caregivers to have an option to choose which technique they need for the task at hand, and to perform the necessary repositioning or lifting without having to change the sheet beneath the patient.
This application describes examples of a patient repositioning apparatus that can serve as both a patient repositioning sheet and a patient sling. The patient repositioning apparatus includes a sheet with multiple handles and multiple strap members. The sheet has an upper surface and an opposing lower surface and defines an outer periphery that has opposing side edges. The upper surface of the sheet includes an upper surface material, and the lower surface of the sheet includes a lower surface material that is formed from a relatively low-friction material as compared to the upper surface material. The handles are disposed along the opposing side edges of the sheet, and the strap members are attached to the sheet and distributed across both opposing side edges. Each of the strap members includes a strap portion that forms at least one bight in the strap member, and preferably plural bights. The bight can be used to secure the strap member to a lifting device.
This application also describes kits that include patient repositioning apparatuses and other equipment. For example, the kits may include a patient repositioning apparatus as described above, and a lifting mechanism with mechanical hoist and a strap connector arm that has hooks sized to engage the strap members of the patient repositioning apparatus. Additionally and/or alternatively, a kit can include a wedge (or multiple wedges) that are configured to support a patient in a partially recumbent or reclined position. The wedge includes a base and an inclined portion. The materials forming the surfaces of the base and inclined portion can be selected to have similar or differing friction levels depending on the intended use of the wedge.
This application also describes examples of methods for repositioning and/or transferring a patient using the patient repositioning apparatuses described herein. The methods include positioning a repositioning apparatus (e.g., a patient repositioning apparatus as described above) on a resting structure, such as a hospital bed or gurney, and then positioning a patient on the repositioning apparatus. The methods may include using handles of the repositioning apparatus to move and/or slide the patient along a resting structure, or from one resting structure to another. The methods may also include repositioning the patient and the patient repositioning apparatus so that the patient rests in a recumbent position upon one or more inclined wedges, such as by rolling or sliding. Some methods also include engaging the strap members of the patient repositioning apparatus with a connector arm of a lifting mechanism, and lifting the patient. Once lifted, the patient can then be repositioned on the resting structure, or moved to another structure, such as a different hospital bed, a gurney, an operating table, or a wheelchair.
This application refers to relative friction levels among the various surfaces of a patient repositioning apparatus. Generally speaking, a friction level is dependent on a number of factors, including the material forming the surfaces of the sheet, the corresponding surface engaging with the sheet to generate the friction, and the normal force acting between the two surfaces. In this application, a “low friction” or “lower friction” surface is a relative term that refers to the relative frictional forces generated when two surfaces are tested under similar conditions. For example, to test the relative frictional forces between two surfaces, Surface A and Surface B, a 4 kg iron block may be placed onto each surface, and the dynamic and static frictional forces necessary to move or initiate movement the block are measured. Where the measured dynamic and/or static forces for Surface A are relatively low compared to those measured for Surface B, Surface A will be considered a relatively “low friction” surface, and Surface B will be considered a relatively “high friction” surface. In general, a “low friction” surface will generate a relatively low friction coefficient σ compared to a “high friction” surface when tested using a similar iron block. It should be noted that the terms “high friction” and “low friction” are terms of relativity applied among multiple different materials, but these terms are not meant to convey any absolute value or range of values.
In general, surfaces formed from plastics, vinyl, and similar materials tend to make for good “low friction” surfaces that facilitate sliding and gliding along or between medical resting structures (e.g., hospital beds and gurneys). However, these materials tend to be cool, stiff, and uncomfortable, and do not generally make for a suitable surface that a patient can rest upon. Softer resting surfaces, such as those made from textiles, cloths, microfibers, and the like, will be generally more comfortable for a patient to rest upon. However, these softer surfaces tend to generate higher friction coefficients compared to those of the mentioned “low friction” materials. Accordingly, the patient repositioning apparatus may comprise multiple layers, each formed from a different material, so that the upper resting surface is formed from the softer high friction material, whereas the underside surface is formed from a sleeker, lower friction material. This higher friction, softer upper surface not only provides added comfort to a patient, but it also inhibits the unwanted slipping of the patient relative to the sheet during repositioning. In some embodiments, the low-friction material may be nylon and the high-friction material may be microfiber. It is not necessary that the low friction material be completely excluded from the upper surface, and thus, for example, the sheet may be composed of a sheet of high friction material secured to a slightly larger sheet of low friction material. Similarly, it is not necessary that the high friction material be completely excluded from the lower surface. Generally, other materials can be used in fashioning the sheet.
The patient repositioning apparatus may be of any suitable size and shape, and can be the same size as a standard sheet for a hospital bed or other support surface so that the repositioning apparatus can be fitted to the bed and serve as the bed sheet. The support surface may be any structure capable of supporting a resting patient. For example, the support surface can be a hospital bed (or a standard bed), a gurney, a wheelchair, a reclining chair, an operating table, or testing/scanning equipment (e.g., an X-ray or CAT scan device), to name a few options.
The term “patient repositioning apparatus” used throughout this application refers to a device that can operate as both a sheet and a sling. As such, this application may refer to the apparatus as either a “sheet” or a “sling,” but any such references should not be limited to one particular functionality.
As shown in
With reference to
The sheet 120 can be formed of a variety of materials, and in some embodiments, the sheet 120 includes multiple layers. The multiple layers form opposing sheet surfaces 122/124, each of which may be formed from different materials. For example, an upper surface 122 of the sheet 120 may be configured to provide a soft, comfortable surface for a resting patient, and may therefore be formed from softer high friction material such as cotton, microfiber or other textiles. Conversely, the opposing lower surface 124 may be formed from low friction material to facilitate sliding of the patient repositioning apparatus 100 on the resting structure 10. The lower surface 124 can be formed from a synthetic material, such as a plastic, vinyl, or the like.
The embodiment in
In some examples, each side of the sheet 120 may have a different number of strap members 160 extending therefrom. Further, some examples may have one or more strap members 160 extending from the upper 136 or lower 138 edges of the sheet 120, depending again on the corresponding equipment used with the patient repositioning apparatus 100.
The strap members 160 are configured to attach to the sheet 120 via securement locations 161 along the first and second side edges 130/132 of the sheet 120. The securement locations 161 may include two or more sealing points comprising stitching, welding, or another mode of attachment, and used to secure ends of the strap members 160 to the sheet 120, as described further below and shown in more detail in
Some examples of the patient repositioning apparatus 100 may include retaining members (not shown) that extend from the sheet 120, which are configured to help hold or secure the patient repositioning apparatus 100 onto a resting structure. The retaining members may include bands, belts, or straps designed to wrap around a portion of the resting structure, and engagement structure, such as clips, buttons, snaps, hook and loop fasteners, or the like.
The patient repositioning apparatus 100 also includes one or more handles 140 on the underside of the sheet 120 that help a caregiver 20, or multiple caregivers, move and/or reposition the patient repositioning apparatus 100 on or between resting structures. As seen in
Extending between the various sealing points 144, the band 142 will form an un-attached portion that serves as a gripping portion 146 of the handle 140. In this way, the patient repositioning apparatus 100 may include multiple handles 140 positioned along the entire length of the underside 124 of the sheet 120, thereby offering a caregiver a variety of options for gripping locations when moving a patient. The sealing points 144 can be arranged to affix both a portion of the handles 140 and a portion of the strap members 160 to the sheet 120, as shown with respect to securement locations 161, such that one stitching pattern secures both objects to the sheet 120. The handles can also attach to the sheet 120 via sealing points 144 placed at intermediary securement locations 169 between the securement locations 161 that affix the strap members 160 to the sheet 120, thereby providing multiple handles that offer multiple gripping locations along the sheet. In some examples, the patient repositioning apparatus 100 may also include a handle or handles 150/151 attached to the upper edge 136 of the sheet 120 (as shown in
In other examples, a patient repositioning apparatus may include only a single handle 140 on each side of the sheet 120, secured at two locations. In still other examples, each side of the sheet 120 may include a plurality of handles, each formed from a separate band or series of bands that are separately and individually attached to the underside of the sheet 120. In other examples, the handles 140 may be formed on the upper surface 122 of the sheet 120. In yet further examples, the handles 140 may be formed as a part of the sheet 120 itself, for instance, by way of slots cut into the sheet, or tabs, knobs, strips, or other features that extend from the sheet 120. And in embodiments where the sheet is a non-rectangular shape, the handles may be formed in the side edge or edges that define the outer peripheral shape of the sheet, such as the perimeter of a round or elliptical shaped sheet.
As shown in
The sealing points 144 securing the handles to the sheet 100 can also serve as the sealing points that attach the strap members 160 to the sheet 100 (for clarity,
As shown in
In some forms, the patient repositioning apparatus 100 may be provided as a component of a kit that includes a lifting device, such as the lifting device 200 shown in
As seen in
The patient repositioning apparatus 100 also may be used for patient repositioning without a lift, as shown in
The patient repositioning apparatus 100 described in this application can be used in a variety of environments, and in connection with a variety of other equipment and components. For example, the patient repositioning apparatus 100 can be used with a disposable dry pad that can be placed between the patient repositioning apparatus 100 and the patient 1 to absorb fluids and manage moisture that may develop between the patient and the patient repositioning apparatus 100.
In some circumstances, the patient repositioning apparatus 100 can be used along with a system designed to assist continued movement and repositioning of the patient. Such systems can include wedges upon which the patient can be positioned to situate the patient in a partially recumbent position. As shown in
The wedges 400 each have a base surface 420, which is designed to engage with the mattress of a hospital bed or other support surface, and an inclined surface 440, which supports the patient. The wedges 400 can be formed from a flexible material such as a foam, and can be provided in varying levels of stiffness. The base surface 470 comprises a generally high friction material to inhibit unwanted movement or sliding of the wedge 400 along a resting surface when a patient rests there upon. In some examples, the inclined surface 440 can include the same material that forms the base surface 420, but in other examples, the inclined surface 440 is formed from a low friction material relative to that of the base surface. Using such a low friction material on the inclined surface 440 can help a caregiver position a patient onto the wedge or wedges by sliding the patient and the repositioning apparatus up along the wedge. In such an embodiment, because the inclined surface 440 and the underside 124 of the patient repositioning apparatus 100 are relatively low friction materials, the caregiver will experience relatively low resistance when sliding the patient onto the wedge 400. In
In addition to the sliding technique shown in
With reference now to
One need not necessarily perform all of the aforementioned steps in the order described above. For example, the method may perform the lifting step 560 before the sliding step 530. Further, the method does not necessarily require performance of all of the aforementioned steps. For instance, some methods may only perform one or some of the aforementioned steps. However, where the method involves using examples of a patient repositioning apparatus and the corresponding equipment (e.g., lifting mechanisms, resting structures, wedges, etc.) as disclosed herein, each of the aforementioned method steps would at least be available options.
