Description

[Technical field]

[0001] The present disclosure relates generally to patient transport in hospital and clinical environments and other medical or patient treatment settings. In particular, the present disclosure relates to a patient transfer system for moving a patient from one surface to another, for example, between beds or stretchers in an operating room or in an examination, laboratory, treatment, or recovery area. [Background technology]

[0002] In the daily operation of a hospital, patients are frequently moved from one surface to another. In many cases, patients are not ambulatory and are moved via stretcher with the assistance of nursing and / or medical staff. For example, when a patient undergoes surgery, even an ambulatory patient may be treated as non-ambulatory due to operational and / or anesthesia effects.

[0003] Non-ambulatory patients are typically moved via stretcher whenever there is a need to move the patient to a new area. For example, after a surgical procedure, nursing and / or medical staff typically transfer the patient to a stretcher for transport from the operating room to a recovery room. Generally, the patient remains on the stretcher while in the recovery room. During recovery, the patient is moved on the stretcher to a hospital room. Once in the room, the patient is moved from the stretcher to a hospital bed by nursing and / or medical staff.

[0004] Several prior art devices used to move patients are disclosed in U.S. Patent Nos. 4,528,704, 5,483,709, 6,073,291, 7,007,330, 7,415,738, 7,574,761, and 9,314,388, and U.S. Patent Publication Nos. 2003 / 0159212, 2005 / 0076437, 2013 / 0042414, and 2016 / 0367422, each of which is incorporated herein by reference. The present disclosure discloses devices that provide improvements and / or alternatives to these prior art devices. [Prior art documents] [Patent documents]

[0031] 1A is a perspective view of an air-supported inflatable patient transport system 100. As shown in FIG. 1A, the patient transfer system 100 includes an inflatable air-supported support apparatus or device 101 having an axial split or slit 102 defining two separable longitudinal sections 104 and 106 joined together along a releasable seam 118 that extends from a proximal or head region 108 of the device 101, through a central torso region 110 and a lower leg or leg region 112, toward a foot region 113.

[0032] The patient transfer system 100 is designed to move a patient from one lateral surface to another and to be easily removable from under the patient without the need for additional rotational or other disturbance to the patient's body after transfer. For example, the inflatable device 101 can be placed under the patient in a deflated state before starting a medical procedure, and after the procedure is completed, the device 101 can be inflated with the patient positioned on the upper surface 130 (e.g., at the central portion 132 within the boundary 134) without rotation or other substantial physical manipulation of the patient's torso by the caregiver. Using an air blower (such as a high-volume air blower), the system 100 can also be provided with sufficient airflow via one or more ports or inlets 146, so that the air-bearing patient support 101 floats and is at least partially supported on a bed of pressurized air, with the pressurized air escaping through small holes on the bottom side, thereby reducing friction and allowing reduced or minimal force required to move the patient.

[0033] A patient can be strapped to the patient support 101 using one or more straps 122 with adjustable couplings 126, and the patient is transferred, for example, by sliding the patient support 101 along a transfer surface (or from one surface onto another) using one or more handles 140, 142. After patient transfer is completed, the system 100 is retracted and the patient support 101 is removed from under the patient, for example, by using removal tabs or handles 140 to pull the device 101 apart in opposite directions, splitting the main body portion of the support 101 along a central or midline axis A into two separate longitudinal sections 104 and 106.

[0034] Starting at the patient's head region 108 and moving through the torso region 110 toward the lower leg region 112, the longitudinal sections 104, 106 of the patient support 101 easily peel away on each side from under the patient's torso region 110, which is the area of ​​greatest weight and mass. In some embodiments, the longitudinal sections 104, 106 remain connected by the lateral sections 114, for example at the foot region 113. After use, the system 100 may be disposed of in compliance with local regulatory and hospital protocols for safety, hygiene, and surgical disposal.

[0035] Conventional inflatable "floating" transfer devices generally require patient manipulation to remove the device from under the patient. In contrast, patient transfer system 100, due to the unique design and construction of patient support 101, does not require additional patient manipulation for removal, allowing system 100 to be removed by separating air-bearing patient support 101 along its center or axis A.

[0036] FIG. 1B is a plan view of an alternative patient transfer system 100. In contrast to the embodiment of FIG. 1A, which may be manufactured from woven materials using a machine sewn construction process, the patient transfer system 100 of FIG. 1B may be formed from a welded polymer sheet design. In this process, the top and bottom layers of the patient support 101 are "stamped" together or placed one on top of the other and welded together at the periphery 125 to define the inflatable air-bearing patient support 101. Suitable welding processes include, but are not limited to, heat welding, chemical welding, and radio frequency (RF) welding methods. Additional welds may be used to define or attach other features such as handles 140 and tabs 142, along with additional features such as internal baffles and extended handle structures 141 on one or both ends of the patient support 141.

[0037] Depending on the application, a perforated longitudinal seam 118 can be used to secure the longitudinal sections 104, 106 together across the axial separation 102 during the transfer process and to serve as a release point or mechanism to separate the sections 104, 106 after transfer. This configuration provides the “air mattress” assembly or patient support device 101 as a substantially single unit that is substantially continuous and formed from a unitary or homogenous material, as opposed to using a divided unit with two separate sections joined by an intermediate tear surface formed from different materials, for example, a fabric web or woven material as envisioned in the sewn construction of the patient support 101.

[0038] The air retention and pressure seal features of the system 100 defining the inflatable patient support 101 may include one or more internal baffles 160 extending longitudinally on either side 104, 106 of the perforated seam 118. Perforating the patient support 101 through the inflated area may result in air loss and premature separation, but as explained above, small air-bearing flow openings may be formed on the bottom surface and the perforated seam 118 may be defined with a sufficient width to form a pressure seal about the periphery of each perforation to maintain internal pressure within the longitudinal sections 104, 106. The welded, substantially one-piece fabrication of the air-bearing device 110 may also substantially reduce system weight and manufacturing costs as compared to conventional devices.

[0039] Figure 2 is a bottom perspective view of patient transfer system 100 in a machine sewn construction, such as that shown in Figure 1 A. The features shown in Figure 2 are equally suitable for a welded polymer construction, such as that shown in Figure 1B.

[0040] The inflatable patient transfer system 100 is configured to support the patient's body on the inflated patient support 101 and distribute the patient's weight more evenly over the bottom surface 150, reducing friction and facilitating patient transfer. As shown in FIG. 2, the bottom surface 150 of the support 101 may also include a number of small openings, perforations, or holes 152, which are configured to allow air inside the inflated bed or patient support 101 to escape in a controlled manner, thereby providing a cushion of air flowing underneath the bottom surface 150.

[0041] Depending on the design, sufficient airflow can be generated through the holes or openings 152 to at least partially support the bottom surface 150 and reduce frictional contact with the transfer surface to move the system 100 while the patient is lying on the patient support 101. In certain applications, the airflow can be sufficient so that the patient support 101 floats above the transfer surface along a portion or substantially all of the bottom surface 150. More generally, the patient support 101 can be adapted to utilize a combination of weight redistribution, airflow, and reduced friction materials in the bottom surface 150 to effect patient transfer more easily and efficiently.

[0042] For example, a number of small apertures 152 may be formed in a core area 154 disposed in a central portion of the bottom surface 150 that may be recessed relative to a reduced friction boundary area 156 extending around the periphery of the device 101 to create a weight-bearing layer of air below the core area 154 and support the system 100 during patient transfer. More generally, the airflow may be sufficient to at least partially support any or all of the bottom surface 150 of the device 101 and facilitate sliding the system 100 along or from one transfer surface to another (e.g., between an operating table, examination table, or other surface on which a medical procedure is performed, a bed or stretcher for patient transport, or along or between any such surfaces).

[0043] Figure 3A is a perspective view of patient transfer system 100 in a partially detached configuration with longitudinal sections 102 and 104 removed in the proximal (head) region 108 of patient support 101. Figure 3B is an alternative perspective view of patient transfer system 100 in the substantially one-piece material embodiment of Figure 1B, for example.

[0044] 3A and 3B, the patient transfer system 100 includes a cleft or split 102 extending along the center of the patient support 101. The split 102 typically extends longitudinally along the longitudinal dimension of the patient support 101, for example, along a centerline or midline defined by the longitudinal axis A of the patient support 101, as shown in FIG. 3, to divide the support 101 into two separate generally symmetrical half-sections 104 and 106. Alternatively, the split 102 need not be defined along the midline A, and other diagonal and asymmetric splits are also envisioned.

[0045] The cleft 102 generally extends along at least a portion or a majority of the length of the inflatable patient transfer support 101 such that the patient's torso and other heavier portions are disposed above the cleft 102 that divides the two longitudinal sections 104, 106. As illustrated in Figures 3A and 3B, for example, the cleft 102 extends through the head region or proximal portion 108 (configured to support the patient's head), the torso region or mid portion 110 (configured to support the patient's torso or shoulder / back / hip regions), and at least a portion of the lower body or leg portion 112 (configured to support the patient's lower limbs or legs) of the support device 101.

[0046] The patient's head, shoulders, back, buttocks, and at least a portion of the patient's legs can therefore be supported on the upper surface 130 of the device 101 across the cleft 102 that divides the divided longitudinal sections 104 and 106. The cleft 102 and seam structure 118 can terminate in an unaffected (undivided) lateral section 114 at distal end sections 112, 113 of the support 101 that are configured to support an area of ​​lesser total patient mass, such as the patient's feet, and in some cases, the lower portions of the patient's legs.

[0047] After the patient transfer system 100 has been contracted, the divided sections 104 and 106 of the support bed or device 101 can be separated laterally from one another by medical staff or other caregivers to remove the divided sections 104, 106 from under the heaviest parts of the patient (extending to the patient's head, torso, shoulders, back, buttocks, etc., and possibly at least the upper portions of the patient's legs). The unaffected lateral section 114 at the distal end 113 of the patient support 101 can then be easily removed from under the patient's feet, an area of ​​substantially less body mass, for example, by sliding the lateral section 114 out along axis A.

[0048] Alternatively, the cleft 102 and seam structure 118 may extend from the proximal region 108 (at the patient's head), through the central (torso) region 110, and through the distal regions 102 (legs) and 103 (feet). In these configurations, the seam 118 may be completely separated along the entire length of the patient support 101, leaving the longitudinal sections 104, 106 divided into two separate parts or halves for removal from both sides under the patient. Depending on the application, the seam 118 may extend through the transverse section 114, separating the section 114 into a part with the longitudinal sections 104, 106, or the transverse section 114 may not be present and a flow port or opening may be provided across the seam structure 118 to provide for communicating flow between the longitudinal sections 104, 106 (see FIG. 7).

[0049] Thus, the inflatable patient transfer system 100 can be removed from beneath the patient with little or no additional torso manipulation or other disturbance to the patient. For example, the inflatable transfer system 100 can be removed from beneath the patient without having to rotate the patient from side to side, as required by existing inflatable transfer devices.

[0050] As further illustrated in Figures 3A and 3B, the inflatable patient transfer system 100 includes selectively engaged joints, e.g., in the form of releasable seams or strips 118, designed to provide a continuous support surface 130 for the patient during inflation and transfer. The releasable seams 118 support the patient's head and / or central section across the gap 102 defined between the two longitudinal sections 104 and 106, providing a substantially continuous upper surface 130 to support the patient and avoid discomfort during the transfer process. The seams 118 may also be adapted to control selective separation of the longitudinal sections 104, 106 from one another. For example, the seams 118 may be configured to at least partially hold the two sections 104, 106 together while being inflated for patient transfer and to control the amount of force required to separate the sections 104, 106 after the transfer process is complete.

[0051] More generally, the releasable seams or strips 118 of the inflatable transfer system 100 can be configured such that the releasable seams or strips 118 will not separate under pulling forces (or similar lateral forces or tension loads) while the patient support device 101 is being inflated and during the patient transfer process. Conversely, the releasable seams or strips 118 can be configured to yield and separate under forces when the patient support 101 is deflated, for example, by using a directional seam material that yields under directional forces when the patient support 101 is deflated (e.g., directional forces with a vertical component that is substantially transverse to the seam or strip 118, or substantially transverse or perpendicular (orthogonal) to the plane of the patient support 101).

[0052] Seam 118 may be made from a variety of suitable materials and attached to system 100 along cleft 102 using a variety of methods to achieve these properties. In some embodiments, for example, releasable seam 118 comprises a releasable adhesive or mechanical attachment feature, such as a non-stick glue, a hook and loop (e.g., VELCRO®) fastener system, or a polymeric, cellulosic, woven, or tear strip material adapted for selectively engaged joints, that is sufficiently strong to maintain sections 104, 106 in contacting relationship when system 100 is inflated and a patient is supported on device 101, yet allows cleft sections 104, 106 to be easily pulled away from one another after transfer by nursing staff, medical staff, or other caregivers.

[0053] The releasable seam 118 may extend along some or all of the length of the cleft or fissure 102. The seam 118 may be exposed and visible along one or both of the upper and lower surfaces 130 and 150 of the patient support 101, as shown. In embodiments in which the cleft 102 extends the entire length of the patient support 101, the seam 118 may temporarily join or attach the sections 104, 106 together to support a patient. The releasable seam 118 may be configured as a directional separation seam or a gapless separation seam, or a similar selectively releasable attachment mechanism.

[0054] The inflatable patient transfer system 100 may include securement features for securing the patient to the support apparatus 101. For example, the system 100 may include one or more adjustable straps 122 for securing the patient to the upper portion 130 of the support 101. The straps may also maintain alignment and positioning of the patient relative to the support apparatus 101 during inflation of the patient support 101 and during the patient transfer procedure. Existing transfer devices generally use hard plastic or metal buckles, which may cause discomfort to the patient or to the operator under certain conditions. In contrast, the straps 122 may be formed from a flexible fabric adapted for strength and patient comfort, and for ease of use by the operator (e.g., nurses and medical staff or other caregivers).

[0055] Straps 122 may be used to secure the patient to the inflatable support 101 during transfer. For example, a first strap 122 may be configured to wrap around a chest or torso region of the patient and a second strap 122 configured to wrap around a lower leg region of the patient to secure the patient to the upper surface 130 of the patient support 101. One end of the first strap 122 is attached to the first longitudinal section 104 in the central or torso region 110 of the support 101, and the other end of the first strap 122 is attached across the patient's body to the central or torso region 110 of the second longitudinal section 106. Similarly, one end of the second strap 122 is attached to the first section 104 in the lower body or leg region 112, and the other end of the second strap 122 is attached across the patient's lower body or leg to the lower body region 112 of the second section 106.

[0056] The straps 122 include adjustable buckles or couplings 126 for tightening the straps 122 around the patient to secure the patient to the transfer system 100. Each of the straps 122 may include one or more such adjustable couplings 126 for adjusting the length of the straps 122. Each coupling 126 may be attached to a first segment of the respective strap 122 (such as the segment attached to the first section 104 of the patient support 101), and each coupling 126 may define a connector (e.g., a loop or similar opening through which a respective end of the strap 122 is threaded) for receiving a second segment of the respective strap 122 (such as the segment attached to the second section 106 of the patient support 101) to secure the two segments together around the patient. The end of the strap segment that is threaded through the loop or similar connector element at the adjustable coupling 126 may then be selectively attached, such as via friction engagement or a releasable hook and loop fastening system, to a portion of the strap segment that is not threaded through the opening to secure the strap 122 in a desired position around the patient. The adjustable linkages 126 can be made from a variety of sturdy, yet soft and compliant materials, such as compliant plastic elastomers, compliant polymers, woven fabrics, and other textile materials.

[0057] The system 100 may be provided in a skin-friendly configuration in which the top surface 130, bottom surface 150, and other exterior surfaces of the patient support 101 are formed from materials suitable for direct contact with the patient's body, clothing, and skin. Alternatively, the exterior surface materials may be formed from non-breathable, non-absorbent, and substantially impermeable surface materials, such as nylon-coated PVC (polyvinyl chloride) or TPU (thermoplastic polyurethane) materials or other suitable polymers, which may be used in conjunction with a skin-friendly removable (single-use) pad or linen component that is placed between the top surface 130 of the device 101 and the patient to prevent skin contact, skin shear, or friction injury during removal.

[0058] To facilitate lateral separation of the first and second segments 104, 106, the inflatable patient transfer system 100 may include one or more tabs or handles attached to the first and second segments 104, 106 of the patient support device or apparatus 101. The system 100 may include one or more separation handles or tabs 140 attached to the first and second segments 104, 106, the tabs or handle structures 140 adapted for grasping by different operators, including nursing and medical staff or other treatment providers. The handles or tabs 140 may be attached to the head region 108 of the patient support 101. In some embodiments, the handles or tabs 140 may be attached to respective corners of the first and second longitudinal segments 104, 106 near the start or origin of the cleft 102 at the proximal end 108 of the support 101 to facilitate separation of the cleft segments 104, 106 from each other upon deflation of the air-bearing patient support 101 after completion of the patient procedure and transfer.

[0059] To facilitate using the patient transfer system 100 to move a patient lying on the upper surface 130 of the patient support 101, the system 100 may include one or more positioning handles 142 attached to opposing sides of the patient support 101. For example, the system 100 may include multiple handles 142 attached to each side of the outer periphery of the patient support 101. The system 100 may also include handles 142 located within one or more of the head region 108, torso region 110, lower body or leg region 112, and foot region 113 to facilitate moving a patient lying on the upper surface 130 of the patient support 101.

[0060] The inflatable patient transfer system 100 may also include one or more fill ports or inlets 146 for inflating the air-bearing patient support 101. The fill ports 146 may be located at an end of the system 100, for example, at a distal end 112 or 113 proximate a lateral section 114 of the system 100, such that air entering the system 100 flows into both longitudinal sections 104, 106 of the patient support 101 substantially simultaneously, thereby facilitating uniform inflation of the system 100 while a patient is lying on the upper surface 130.

[0061] 3A and 3B, for example, one or more fill ports 146 may be disposed within, adjacent to, or otherwise generally located at a distal end 112 or 113 (in the leg or foot region of the patient's body) of the support 101 opposite the beginning of the cleft 102 at the proximal end 108 (in the region of the patient's head). In one particular example, the system 100 includes three fill ports 146, one of which is located along the centerline or midline A of the patient support 101 and aligned with the cleft 102 between the longitudinal sections 104 and 106, and the other two of which are located on either side or at the corners of the lateral section 114. Alternatively, the patient transfer system 100 may include one, two, three or more fill ports 146 positioned to provide airflow to the longitudinal sections 104, 106 and any lateral sections 114 of the inflatable patient support 101.

[0062] The inflatable patient transfer system 100 may include a plurality of interior baffles 160 that direct air flowing through the interior of the patient support 101. Each baffle 160 may be formed from a substantially oval or rectangular sheet of polymer or other suitable material with a top edge attached to the inside of the upper surface 130 of the patient support 101 and a bottom edge attached to the inside of the lower surface 150 of the patient support 101. One or more baffles 160 may extend transversely to the centerline A of the system 100 in each of the longitudinal sections 104 and 106 and in the lateral section 114. As illustrated in FIGS. 1-3 , a plurality of baffles 160 may extend transversely (e.g., perpendicularly) to the cleft 102 in the core areas 132, 154 of the upper and lower surfaces 130, 150 of the system 100.

[0063] (Removable sheet applied) 4A is a side view of patient transfer system 100 with removable transfer sheet 131. FIG 4B is an end view of patient transfer system 100 also showing removable transfer sheet 131.

[0064] 4A and 4B, the pneumatically supported patient support 101 is inflated for use in transferring a patient or body along one or more transfer surfaces 210, for example, between a hospital bed and a stretcher, or between a bed or stretcher and a surgical or examination table. Transfer sheet components 131 suitable for use with the system 100 include, but are not limited to, single use transfer sheets such as those described in U.S. Patent No. 9,101,521 to White and Emerson, entitled "SYSTEMS, METHODS AND TRANSFER SHEETS FOR TRANSFERRING PATIENTS," which is incorporated herein by reference.

[0065] 3A, 3B and compare to FIGS. 4A and 4B, the upper surface 130 of the air-bearing patient support 101 can be configured to enhance material / skin interaction or a removable pad or cloth component 131 can be provided between the device 101 and the patient. The upper surface 130 or the removable sheet component 131 can have absorbent properties to contain fluids (e.g., blood and other bodily fluids) present or produced during the medical procedure and subsequent patient transfer. In some embodiments, the absorbent core or central area 132 of the upper surface 130 can be provided, for example, recessed relative to a complementary peripheral border area 134, whereby fluids are drained or directed into the core absorbent area 132.

[0066] The core area 132 may be configured to absorb any such fluids produced during the procedure and transfer, while the peripheral boundary area 134 may be relatively impermeable and configured to direct fluids toward the core area 132 for absorption. The system 100 may be provided in a single-use or disposable configuration so that any fluids absorbed by the system 100 can be disposed of in a sanitary manner in accordance with approved medical protocols. The system 100 may also allow for reuse and single-patient use. In various embodiments, the top surface 130 of the patient support apparatus 101 may be substantially impermeable and a removable absorbent sheet may be placed on the top surface 130. In various embodiments, a compatible disposable cover may be placed over the patient support apparatus 101 such that the apparatus 101 may be reused with a new disposable cover.

[0067] (Patient Support and Joint Structure) Figure 5A is a top view of patient transfer system 100 showing head and torso regions 108, 110. Figure 5B is a perspective cross-sectional view of system 100 showing the internal structure including baffle 160 and a detailed view of releasable seam 118.

[0068] 5A and 5B, the releasable seam 118 extends from the head region 108 toward the torso region 110 of the patient support 101. A separation handle or tab 140 can be provided in the head region for separating the longitudinal sections 104, 106 after patient transfer is complete.

[0069] The releasable seams or strips 118 are configured to maintain the connection between the longitudinal sections 104, 106 against lateral forces or tension loads experienced upon expansion of the patient support 101, and to yield so that the sections 104, 106 may be separated when the patient support 101 is deflated. Depending on the application, the seams 118 can thus be formed from a range of suitable materials adapted to selectively engage and maintain the longitudinal sections 104, 106 together in a contacting relationship when the patient support device 101 is inflated, and which allow adjacent sections 104, 106 to be detached and pulled away from one another following transfer by nursing, medical, or other caregiver staff.

[0070] For example, the perforated seam 118 can be formed from a substantially continuous material across adjacent sections 104 and 106, or a directional release material or tear strip can be used that yields under a directional force with a sufficient vertical component (a vertical component that is substantially transverse to the seam or strip 118 and substantially transverse or perpendicular to the plane of the patient support 101). In a perforated seam embodiment, the releasable seam 118 can be formed from the same substantially continuous, one-piece material as the longitudinal sections 104 and 106 that extend longitudinally along the upper surface 130 of the patient support 101.

[0071] In some embodiments, the seam 118 can be exposed and visible along the upper surface 130 of the patient support 101 above the gap or cleft 102 between the longitudinal sections 104, 106. Alternatively, the seam 118 can extend downward into the vertical cleft 102 to define a vertical web attachment structure between the longitudinal sections 104, 106.

[0072] (Air Supply Connections and Adapters) 6A is a perspective view of a flow connection or hose 166 for an air-supported patient transfer system. Air can be supplied to the interior of the patient support via a blower or other air source coupled to one or more of the fill ports or inlets.

[0073] Figure 6B is a perspective view of a flow coupling adapter 190 for use in coupling a blower or other compressed air source to an inlet port on a patient support device, for example, using a hose or similar flow structure 166 as shown in Figure 6A.

[0074] 6A, 6B, and 6C, the patient transfer system may include an air hose 166 that may be attached, for example, to any of the fill ports of the patient support at a first end 168 and to a blower or compressed air source at the other end 170. The first end 168 may be adapted for attachment to one or more fill ports 146 on the patient support 10 as described herein using, for example, a tubular or conical coupling member 174 with a substantially circular cross-sectional shape that may be inserted into the selected port 146 and secured using a snap, ring, hook and loop attachment, or other selective mechanical coupling and sealing arrangement. The coupling section 174 may taper inwardly as it approaches the terminal end 168 from the hose section 184 to facilitate insertion into fill port openings 146 of various sizes. In some embodiments, the coupling section 174 is frusto-conical.

[0075] The source coupling end 170 of the air hose 166 can be adapted for attachment to a blower or other external air source, for example, by means of a cylindrical end portion 178 having an engagement feature 180 annularly recessed behind the end portion 178. The couplings 174 and 178 / 180 can be formed as integral or separate coupling components on each end of the expandable hose section 184 and can be interchanged without loss of generality.

[0076] The collapsible section 184 of the hose 166 is expandable to accommodate different lengths suitable for connecting an air source to a selected fill port 146 on the patient support 101. The air hose 166 may be pre-attached and stored with the patient support 101 during manufacture, or attached to the patient support 101 at the time of use. Thus, the air hose 166 may be reusable or provided in a disposable configuration for single use applications in combination with the air bearing patient support 101 and other disposable components of the patient transfer system 100.

[0077] In single use or disposable embodiments, the hose 166 may be formed from paper, nylon, fabric, or other suitable polymeric or woven materials that are expandable and collapsible in both length and diameter to accommodate compact storage with the air-bearing patient support 101. In these embodiments, the coupling 174 may take the form of a pre-attached or pre-sewn connection to the air-bearing support device 101, for example, the first end 174 of the hose 166 is sealed to a selected port 146. The second end 180 of the hose may also be provided in a collapsible form and adapted for coupling to a blower or other compressed air source using a friction fit, or a compression ring or band seal mechanism.

[0078] In some of these embodiments, the hose 166 can be adapted to be compressed or folded and stowed for substantially flat storage with the air-bearing patient support 101, so that the hose section 184 is not extended until desired for connection to an air source. Once patient transfer is desired, the coupling end 180 of the hose 166 can be unfolded, extended, and attached to a blower or other air source for use. This is in contrast to prior art designs in which the hose 166 can be heavy and cumbersome, posing a tangling hazard.

[0079] The inflatable patient transfer system 100 may also include a hose coupler or adapter 190 to facilitate coupling of various blower and air source systems to selected fill ports 146, either via the hose 166 provided with the patient transport system 100 or using another existing hose component. With reference to Figures 6B and 6C, for example, the system 100 may include an adapted hose coupler 190 designed to connect between one or more ports 146 on the air bearing patient support 101 and a third party source hose system, or between the hose 166 supplied with the system 100 and the outlet of a third party blower or air source.

[0080] As illustrated in FIG 6B, a hose coupling or adapter 190 may be configured for coupling an existing hose 166 to a port or vent 146 of the patient support device 101 and for coupling the hose 166 to a specific blower or air delivery component. As illustrated in FIG 6C, a universal hose coupling or adapter 190 may provide a first interface 192 adapted for coupling to a port 146 on the air bearing patient support 101 and a second interface 194 configured for coupling to a variety of different hose systems, for example, using a compression hose fitting. Alternatively, the first interface 192 can be adapted for coupling to an end 170 of a hose 166 supplied with the patient transport system 100, for example, the other end 168 of the hose 166 is attached to a port 146 on the air bearing patient support 101 as described above. In these embodiments, the second interface 194 can be adapted for coupling to either another hose component or to the outlet of a suitable blower or other compressed air source, which can be provided in a dedicated (customized) configuration or by a third party (generic) vendor.

[0081] In a custom embodiment, the adapter 190 may have simplified interfaces 192, 194 for coupling the end 170 of the hose 166 supplied with the patient transfer system 100 to the outlet of a selected blower or air source, or for coupling one or more ports 146 to a selected external hose system configured to provide compressed air. Alternatively, one or more custom hose adapters 190 may be provided for use with the system 100 with a corresponding range of specifically identified or pre-selected blowers, air sources, or hose systems. In additional embodiments, the adapter 190 may include an internal or integral compressed air or expansion gas source 195, such as an internal or externally powered blower, compressed air or carbon dioxide cartridges, or other suitable expansion gas source.

[0082] (applicable) The air-supported patient transfer system 100 or support apparatus 101 can be used to transfer a patient across one surface to another (e.g., from a medical stretcher or gurney to a hospital bed or operating table, or vice versa). The system 100, in a deflated state, can be positioned on a first surface and the patient can be placed on an upper surface 130 of the deflated patient support 101 in a supine position (lying on his back) or, alternatively, in a prone position (lying on his front). One or more straps 122 and adjustable couplings 126 can be used to secure the patient to the system 100. The patient support 101 can then be inflated under the patient, for example, with a blower or similar air source.

[0083] Air supplied to the patient support 101 is directed through a plurality of holes 152 on the bottom surface 150 to at least partially support the device 101 and reduce friction while sliding a patient supported on the system 100 from one surface to another. After the patient has been transferred, the support 101 may be deflated and easily removed from under the patient while the patient remains in a substantially stationary position (e.g., lying on their back and rotating their torso from side to side).

[0084] The main body of the air-bearing patient support 101 includes a cleft or split structure 102 to allow for easy removal of the longitudinal sections 104 and 106 from beneath the patient. More specifically, the cleft 102 extends longitudinally along the length of the patient support 101, dividing a substantial length of the support 101 into two separate longitudinal sections 104, 106. The longitudinal sections 104, 106 are joined together by a directional seam or similar selective engagement 118 during transfer of the patient from one surface to another. After transfer, the system 100 can be contracted while supporting the patient, and the sections 104 and 106 can be separated along the cleft 102 via the releasable seam 118.

[0085] Upon deflation, the straps 122 can be separated and the patient is no longer secured to the deflated air bed or support device 101. The releasable seams 118 can be manipulated such that the two longitudinal sections 104, 106 are detached, for example at the proximal ends 108 in the patient's head region, and the sections 104, 106 can be pulled in opposite directions relative to each other to remove the sections 104, 106 from under the patient. In this manner, the system 100 can be removed from under the patient without having to rotate the patient to one side or the other. In embodiments in which the patient support 101 includes an unaffected (undivided) lateral section 114, the contracted lateral section 114 can also be removed without requiring manipulation of the patient's torso, for example, by removing the longitudinal sections 104, 106 opposite the patient's head and torso in the proximal and central regions 108, 110, and sliding the lateral section 114 from under the patient's lower leg or foot in one or both of the distal regions 112, 113.

[0086] A suitable patient transfer system 100 may include one or more of a first inflatable section 104 and a second inflatable section 106 disposed adjacent to the first inflatable section 104, the first and second inflatable sections 104, 106 being configured to support a patient. A selectively engageable or releasable seam 118 may be provided between the first and second inflatable sections 104, 106, for example, the releasable seam 118 is defined across a cleft 102 extending longitudinally between the first and second inflatable sections 104, 106 through at least a portion of the patient's head region 108, body or torso region 110, and lower body (leg) region 112. The first section 104 and the second section 106 are laterally separable along the cleft 102 for removal of the device 101 without rotating the patient to either side.

[0087] The cleft 102 can terminate in a lateral section 114 of the device 101 that extends between the first and second inflatable sections 104, 106 in flow communication therewith, e.g., the lateral section 114 is configured to support the patient in the region of the foot 113. For example, the cleft 102 can extend along a medial axis A of the device 101 such that the first section 104 and the second section 106 are similar or substantially the same and symmetrical about the medial axis A.

[0088] The first and second inflatable sections 104, 106 are also in flow communication with one another (e.g., via the lateral section 114) for simultaneous inflation by an external or integrated air source coupled to one or more ports or inlets 146. The expandable air hose 166 can be adapted to attach the air bed or patient support 101 to an air source for inflating the first and second sections 104, 106, for example, the air hose 166 is configured for single use applications in combination with the air bearing patient support 101. The coupling adapter 190 can also be configured to connect the air hose with one or more different models of external air source or with an integrated or internal adapter and compressed air or gas system 190.

[0089] The patient transfer system 100 may include a releasable seam 118 extending along the gap 102 defined between the first and second inflatable sections 104, 106, e.g., the seam 118 is configured for selective attachment and separation of the first and second inflatable sections 104, 106. Depending on the application, the seam 118 may be configured to extend along the entire length of the gap 102 to provide a continuous support surface for the patient, e.g., a continuous upper support surface 130 extending across the gap 102 between the first and second sections 104, 106 after inflation of the air-supported bed device 101.

[0090] The patient transfer system 100 may also include one or more adjustable straps 122 attached across the first and second inflatable sections 104, 106, the adjustable straps 122 configured to secure the patient to the air bearing support 101. A core absorbent area 132 can be defined on the upper surface 130 of the device 101 for absorbing fluid, for example, a border area or raised feature 134 surrounding the core area 132, the border area 134 being elevated relative to the core area 132 to direct fluid toward the absorbent elements within the core area 132.

[0091] Additional Examples 7 is a cross-sectional view of a patient transfer system 100 as described herein. As shown in FIG. 7, the system 100 includes an air-bearing patient support or "air bed" device 101 with first and second longitudinal sections 104 (front) and 106 (back). A port or inlet 146 is provided in flow communication with the first and second longitudinal sections 104, 106, e.g., via the lateral section 114, and the port or inlet 146 is configured for inflation of the air-bearing support 101 for transfer of a patient (or another's body) 200 across one or more surfaces 210 (e.g., between an operating or examination table and a bed or stretcher, or from one bed or stretcher to another, etc.).

[0092] A selectively engageable joint or seam member 118 extends along the cleft or cleft structure 102 defined between the first and second longitudinal sections 104, 106 (see FIG. 3). The selective joint or seam 118 is configured to attach the first and second longitudinal sections 104, 106 together for body transfer over the air bearing support 101 and to at least partially decouple the first and second longitudinal sections 104, 106 for separation and removal.

[0093] Depending on the application, the selective joint may comprise a directional or selectively releasable seam 118 extending longitudinally between the inflatable sections 104, 106 of the air-bearing patient support 101 from a proximal end region 108 (e.g., in the head region of the patient's body) toward a distal end 112 or 113 (e.g., in the leg or foot region of the patient's body). Alternatively, the patient's orientation may be reversed or another person's body 200 may be transported.

[0094] The releasable seam 118 can be configured to separate the longitudinal sections 104, 106 at the proximal end 108 and separate the sections 104, 106 longitudinally from the proximal end 108 toward the distal end 112 or 113. For example, the releasable seam 118 can extend vertically between the upper and lower surfaces 130, 150 of the patient support 101 and form a web or similar attachment structure along the cleft 102 between the front and back longitudinal sections 104, 106 to maintain attachment of the sections 104, 106 for relocation of the body 200 upon inflation of the system 100.

[0095] The seams are adapted to separate the longitudinal sections 104, 106 upon contraction of the air-bearing support 101 and application of a manual separation force. For example, a manual pulling force or tension load can be applied via one or more separation handles 140 to separate the sections 104, 106 in a direction perpendicular to the tear 102, as described above, or the sections 104, 106 can be separated by applying a suitable separation or lateral, e.g., "tear" force transverse to the tear 102 and transverse to the plane of the patient support 101.

[0096] The selective joint can thus be configured for decoupling of the longitudinal sections 104, 106 at the proximal end 108 without additional manipulation of the patient 200 within the torso region 110 (i.e., without requiring any further rotational movements on the patient 200), for separation of the longitudinal sections 104, 106 to opposite sides of the body 200 along the tear 102 or directional seam 118, and for removal of the air-bearing support 101 from beneath the body 200. The lateral section 114 of the air-bearing patient support 101 is provided in flow communication with the first and second longitudinal sections 104, 106, e.g., the selective joint or seam 118 extends between the first and second longitudinal sections 104, 106 from a central portion of the lateral section 114 to the proximal end 108 of the patient support 101.

[0097] One or more ports or inlet couplings 146 may be disposed within the air bearing patient support 101, for example, within the lateral section 114, and provided for flow communication with the first and second longitudinal sections 104, 106 (e.g., from the ports 146, via the lateral section 114). For example, a suitable port 146 may comprise an inlet coupling for an external blower or other compressed air source, which is configured for inflation of the air bearing patient support apparatus 101.

[0098] An air hose 166 (FIG. 4) can be attached to the inlet coupling 146, for example, the air hose 166 adapted to direct airflow from an external air source to the patient support 101 in a single use application of the transfer system 100. A suitable air hose component 166 includes an expandable or collapsible flow section 184 adapted to direct airflow, the collapsible flow section 184 configured for substantially flat storage in combination with the air-bearing patient support 101 and for extension from the air-bearing patient support 101 for use in inflation. Alternatively, an integrated air source and coupling 190 can be coupled to the port 149, the integrated air source 190 adapted for inflation of the air-bearing support 101 in a single use application of the transfer system 100.

[0099] The selective joint may comprise a longitudinal seam structure 118 configured to define a substantially continuous upper surface 130 of the air-bearing support 101 across the seams 118 and crevices 102 defined between the first and second longitudinal sections 104, 106. Thus, the body 200 may be supported on the substantially continuous upper surface 130 upon inflation of the air-bearing support 101.

[0100] A plurality of internal baffles 160 can be disposed within one or both of the first and second longitudinal sections 104, 106 (or within the transverse section 114). As shown in FIG. 7, for example, the baffles 160 extend vertically between the bottom surface 150 and the top surface 130 of the air-bearing support 101 to provide structural integrity when inflated. The baffles can also extend transversely relative to the longitudinal sections 104, 106 (and relative to the seam 118) and further include one or more ports or openings (holes) 161 adapted to allow longitudinal airflow across the baffles 160 through each section 104, 106, 114 for inflation of the air-bearing support 101. Alternatively, the baffles 160 can extend longitudinally through one or both sections 104, 106, for example, as shown in FIG. 5B.

[0101] The selective coupling may define a selectively severable or releasable seam 118 configured for separation and removal of the first and second longitudinal sections 104, 106 depending on the single use transfer application of the air-bearing support 101. The entire system 100 or components thereof may then be configured for sanitary disposal after the transfer operation and removal from under the patient's body 200. One or more openings 119 may be disposed along the severable or releasable seam 118 and configured for lateral airflow across the gap 102 between the first and second longitudinal sections 104, 106, for example, upon inflation of the air-bearing support 101.

[0102] In some embodiments of the patient transfer system, the selective joint comprises a perforated seam 118 defined between the first and second longitudinal sections 104, 106. For example, the perforated seam 118 may extend along the top surface 130 of the inflatable patient support apparatus 110 and be formed from substantially the same material as the sections 104, 106. Similarly, the first and second longitudinal sections 104, 106 may be formed from substantially the same and continuous material as the transverse section 114 and other components of the patient support 101, with the substantially continuous material 118 extending across the gap or crevice 102 to define the perforated seam 118 between the sections 104, 106.

[0103] Alternatively, the cleft 102 and seam structure 118 may extend through the lateral section 114 for complete separation of the patient support 101 into two separate divided sections 104, 106 that can be independently removed from under either side of the patient 200. Depending on the application, the lateral section 114 may not be present and a flow opening 119 may be provided across the seam structure 118 extending through the lateral section 114 to provide flow communication between the longitudinal sections 104, 106.

[0104] A number of flow openings 152 may also be disposed on the bottom surface 150 of the air-bearing support (see FIG. 2), the openings 152 configured for airflow between the air-bearing support 101 and one or more surfaces 210 across which the body transfer is to be performed. Thus, the patient is at least partially supported on the airflow, which may reduce friction between the bottom 150 of the air-bearing patient support 101 and the transfer surface or surfaces 210 to make the patient transfer easier and with less risk of discomfort or injury to either the patient 200 or the medical worker (or other caregiver) assisting with the transfer.

[0105] One or more adjustable straps 122 can be provided, for example, extending laterally across the patient 200 between the first and second longitudinal sections 104, 106 of the air bearing support 101. The straps 122 can be attached around the periphery of the air bearing support 101 or extend around the bottom surface 150 of the support 101 and can include adjustable clasps, buckles, or similar attachment systems 126 for securing the body 200 to the top surface 130 during the transfer process.

[0106] One or more handles 142 may also be disposed along the periphery of the air bearing support 101, the handles 142 configured for pulling the air bearing support 101 across one or more surfaces to effect transfer of the body 200. Additional handles or pulling tabs 140 may also be provided for detaching the sections 104, 106 and separating the sections 104, 106 along the seam 118 (e.g., after transfer is completed and the patient support 101 is deflated).

[0107] Depending on the application, the air bearing support or bed 101 can include a proximal portion configured to support a head region of the patient's body (proximal section 108), a middle portion configured to support a torso region of the patient's body (middle section 110), and a distal portion configured to support a lower region of the patient's body (distal section 112). The distal portion can also be configured to support the patient's lower limbs or legs and support the patient's feet (distal section 113).

[0108] The selective joints or seams 118 can be configured to attach the longitudinal sections 104, 106 together to support the head region and torso region 200 of the body in the proximal and mid sections 108, 110, respectively, and to separate the longitudinal sections 104, 106 in the proximal section 110 towards the patient's head. The selective joints or seams 118 can be configured to separate the longitudinal sections 104, 106 in a direction proceeding from the proximal section or head (section 108) through at least the mid section or torso (section 110) for removal of the air-bearing patient support apparatus 101 from beneath the body 200 without rotating the torso or otherwise maneuvering the patient from side to side.

[0109] For example, transfer system 100 may include an air-bearing patient support 101 having a lateral section 114 with first and second longitudinal sections 104, 106 extending from the lateral section 114. A port 146 can be provided in flow communication with the first and second longitudinal sections 104, 106, e.g., via the lateral section 114, and the port 146 can be configured at the upper surface 130 for inflation of the air-bearing patient support 101 for transfer of the patient 200.

[0110] A number of flow openings or holes 152 can be disposed on the bottom surface 150 of the air bearing patient support 101, the flow openings 152 configured for air flow from the interior of the air bearing patient support 101 during transfer. Thus, the patient 200 and support apparatus 101 are at least partially supported on the air flow as transfer is accomplished, and the air flow substantially reduces friction between the bottom surface 105 of the support 101 and the surface or surfaces 210.

[0111] A selectively engageable seam 118 can be provided extending between the first and second longitudinal sections 104, 106 from the proximal end 108 toward the distal end 112 or 113 of the air-bearing support 101. The selectively engageable seam 188 can be configured to maintain attachment of the longitudinal sections 104, 106 for displacement of the body 200 upon inflation on the air-bearing support, and to selectively decouple the longitudinal sections at the proximal end for separation and removal upon deflation of the air-bearing support.

[0112] The proximal end 108 of the air-bearing support 101 can be adapted to support a head region of a patient 200, and the selectively engageable seam 118 is configured for separation of the longitudinal sections 104, 106 from the proximal end 108 proximate the head region of the patient 200 through at least a torso region of the patient within an intermediate portion 110 of the support device 101. The seam 118 can be further configured for removal of the longitudinal sections 104, 106 to an opposite side of the patient 200 without further manipulation of the patient's torso region in the intermediate portion 110 of the support 101.

[0113] The selectively engaged seam 118 can also be adapted to define a substantially continuous upper surface 130 of the air-bearing patient support 101, with the seam 118 extending across the breach 102 between the first and second longitudinal sections 104, 106. For example, the first and second longitudinal sections 104, 106 can be formed from a substantially continuous material that also defines a perforated seam 118 extending longitudinally between the sections 104, 106. Upon completion of patient transfer, the seam 118 is configured for separation and removal of the longitudinal sections 104, 106. Following a single-use transfer application of the air-bearing support 101, a disposable cover disposed over the entire system 100 or support 101 can be configured for sanitary disposal.

[0114] A plurality of internal baffles 160 can be provided, for example, extending laterally within one or both of the first and second longitudinal sections 104, 106 and vertically between the bottom and top surfaces 150, 130 of the air bearing support 101. In this arrangement, the baffles 160 can be configured to provide structural support upon inflation of the support 101 while allowing longitudinal airflow along each of the sections 104, 106.

[0115] In some embodiments, one or more straps 122 extend laterally across the longitudinal sections 104, 106 of the air-bearing patient support 101 for securing the patient to the upper surface 103. The device may include one or more handles 142 located along the periphery of the support bed 101 for accomplishing transfer by pulling the patient 200 from one surface 210 to another.

[0116] An absorbent layer portion 132 can be provided or disposed on the upper surface 130 of the air-bearing patient support apparatus 101, the absorbent layer 132 adapted for absorption and disposal of fluids along with the air-bearing apparatus 101 after transfer is completed. A border 134 can be disposed about the absorbent layer portion 132, for example a raised border 134 adapted to direct fluids towards the absorbent layer portion 132. Alternatively, the upper surface 130 of the patient support apparatus 101 can be substantially impermeable and a removable absorbent sheet can be disposed on the upper surface 130.

[0117] Figure 8A is a perspective view of patient transfer system 100 with longitudinal baffles 118 extending along each of the longitudinal sections 104, 106. Figure 8B is an exploded view of air-bearing patient support 101 for the system of Figure 8A.

[0118] 8A and 8B, the top and bottom surfaces 130, 150 of the air-bearing patient support 101 can be formed from separate panels 130A, 150B that are attached together near the perimeter 125 by welding, thermal bonding, RF bonding, chemical bonding, or similar mechanical attachment and pressure sealing processes. An internal baffle 116 is attached between the top panel 130A that defines the top surface 130 and the bottom panel 150B that defines the bottom surface 150 of the patient support 101, with perforations 152 extending along the first and second longitudinal sections in a longitudinal orientation generally parallel to the selectively engageable or releasable seam 118 that extends along the cleft 102 between the sections 104, 106.

[0119] The releasable seams 118 can be provided in a variety of suitable forms, with or without additional releasable attachments or selective joining materials, including perforated longitudinal seams 118 or similar seam structures 118 with suitable release characteristics under lateral or vertical forces. Suitable examples of releasable seams 118 also include separation seam features 118 defined on the interior surfaces of the top and bottom layers or panels 130A, 150B of the inflatable (air-bearing) patient support 101, which are configured to weaken the lateral or lateral structure of the panel material 130A or 105B (or both) adjacent to or parallel to (along) the seam 118 at the welded perimeter 125 (on the same side of the device 101) such that the welding process acts as a separation point or release feature for the seam 118 in response to lateral forces.

[0120] These designs allow for separation of the longitudinal sections 104, 106 along the seam 118 under selective release conditions similar to a perforated seam 118, and in certain embodiments utilize a welding or bonding process to define a release point for the seam 118, as shown in Figures 8A and 8B, without requiring actual perforations extending along the seam 118 or slits 102. Alternatively, a combination process can be used to define the seam 118, for example, a release point is defined along the seam 118 at the welded perimeter 125 adjacent the proximal portion 108 (at the patient's head), with or without perforations along the longitudinal extent of the seam 118 in the central (torso) portion 110 and distal (leg) portions 112, 113.

[0121] FIG. 9A is a top perspective view of an alternative patient transfer system 100. In comparison to the embodiment of FIG. 1A, the patient transfer system 100 of FIGS. 9A and 9B can also be formed from a welded polymer sheet design. In this process, the top and bottom layers of the patient support 101 are "stamped" together or placed one on top of the other and welded together at the periphery 125 to define the inflatable air-bearing patient support 101. Suitable welding processes include, but are not limited to, thermal welding, chemical welding, and radio frequency (RF) welding methods. Additional welds can also be used to define or attach other features such as handles 140, 142, along with additional features such as internal baffles.

[0122] 9B is a bottom perspective view of the patient transfer system 100. The inflatable patient transfer system 100 is configured to support the patient's body on the inflated patient support 101 and distribute the patient's weight more evenly over the bottom surface 150, reducing friction and facilitating patient transfer. As in FIG. 2 above, the bottom surface 150 of the support 101 may also include a plurality of small openings, perforations, slots, or rows of holes 152 that are configured to allow air inside the inflated bed or patient support 101 to escape in a controlled manner to provide a cushion of air flowing under the bottom surface 150. Depending on the design, sufficient airflow may be generated through the holes or openings 152 to move the system 100 while the patient is lying on the patient support 101, and sufficient airflow may at least partially support the bottom surface 150 and reduce frictional contact with the transfer surface.

[0123] 9A and 9B, a drilled longitudinal seam 118 can be used to secure the longitudinal sections 104, 106 together across the axial separation 102 during the transfer process. The seam 118 can act as a release point or mechanism to separate the sections 104, 106 after transfer.

[0124] Figure 10A is a top view of the patient transfer system of Figure 9A showing the separable seam, and Figure 10B is a close-up view of the seam of Figure 10A.

[0125] 10A and 10B, the welds 123 of the top layer 127 and bottom layer 128 may define a separable seam 118. One or more openings, recesses, or score lines 129 may be formed along the releasable seam 118 to facilitate separation of the longitudinal sections 104, 106 along the seam 118. This configuration presents the “air-bearing” or “air mattress” assembly of the patient support device 101 as a substantially single unit that is substantially continuous and formed from a unitary or homogenous (uniform) material, as opposed to the use of a divided unit with two separate sections joined by an intermediate tear surface formed from different materials, for example, a fabric web or woven material as envisioned in the sewn construction of the patient support 101.

[0126] 11A, 11B, and 11C are cross-sectional views of the patient transfer system of FIG. 9A showing an internal configuration, an alternative internal configuration, and an alternative internal configuration, respectively.

[0127] 11A, 11B, and 11C, the inflatable patient transfer system 100 may include a number of interior baffles 160 that direct air flowing through the interior of the patient support 101. Each baffle 160 may be formed from a substantially oval or rectangular sheet of polymer or other suitable material with a top edge attached to the inside of the top layer 127 of the patient support 101 and a bottom edge attached to the inside of the bottom layer 128 of the patient support 101. The baffles 160 may extend along the length of the support 101 and chambers 133 may be formed between the top and bottom layers 127, 128 and adjacent baffles 160.

[0128] In various embodiments, the patient transfer system 100 may include no vertical baffles (see FIG. 11A), all vertical baffles 160 (see FIG. 11C), or a combination of sections with vertical baffles 160 and sections without vertical baffles (see FIG. 11B).

[0129] As illustrated in FIG. 11A, the top and bottom layers 127, 128 may be welded together via welds 123, which may extend along the length of the patient support 101. Adjacent welds 123 may be spaced apart from one another such that a chamber 133 is formed between the top and bottom layers 127, 128 and the adjacent welds 123. One of the welds 123 (e.g., the center or middle weld) may form the separable seam 118 (see FIG. 10B). As illustrated in FIG. 11B, the welds 123 of FIG. 11A are replaced by a baffle 160, except for the center or middle weld 123 used to form the separable seam 118.

[0130] 11C, the patient transfer system 100 may include all vertical baffles 160, where a pair of adjacent baffles 160 may form a cleft 102. The chambers 133 within any of these various structures may be sealed within an air bearing system or air mattress such that the chambers 133 may be separately inflated (e.g., inflating one side to "tilt" the patient or inflating the upper body or legs for positioning or other medical purposes, while inflating the remaining chambers to maintain volume to effect patient transfer).

[0131] Fig. 12A is a perspective view of the patient transfer system of Fig. 9A showing the hose adapter inserted into the port, and Fig. 12B is a partially exploded view of the hose adapter and port of Fig. 12A.

[0132] The patient transfer system 100 may include one or more fill ports. For example, as illustrated in FIG. 12A, the fill port 146 may be disposed within or adjacent to a lateral section 114 of the support 101, or may otherwise be located generally within a distal end 112 of the support 101 (e.g., in the leg or foot region of the patient's body) opposite the beginning of the cleft 102 at the proximal end 108 (e.g., in the region of the patient's head). The fill port 146 may be used to inflate the patient transfer system 100 and facilitate transfer of the patient between surfaces.

[0133] 12A , the inflatable patient transfer system 100 may include a hose coupler or adapter 190 to facilitate coupling the fill port 146 to various blower and air source systems, for example, via a hose 166. As illustrated in FIG. 12A , the hose adapter 190 may be designed to connect to the fill port 146 on the air bearing patient support 101 and a hose 166 that may be a third party supplied hose system or may be supplied with the system 100. The hose 166 may connect to an outlet of a third party blower or air source. The hose adapter 190 may define an internal bore to fluidly couple the patient transfer system 100 to an air source.

[0134] As illustrated in FIG. 12B, the hose adapter 190 may be configured for coupling an existing hose 166 to the port or vent 146. The hose adapter 190 may provide a first interface 192 adapted for coupling to the port 146 on the air-bearing patient support 101 and a second interface 194 configured for coupling to a variety of different hose systems, for example, using a compression hose fitting. The first interface 192 may be configured as a bayonet-style connector. For example, as illustrated in FIG. 12B, the first interface 192 may include one or more protrusions 196 that slide through a passage 197 formed in the port 146 and secure behind an internal step 198 of the port 146 via rotation of the hose adapter 190 relative to the port 146. 12B, hose adapter 190 includes four protrusions 196 spaced equidistantly around the circumference of hose adapter 190 for entry into four passages 197 formed in port 146 and then rotation behind four steps 198 of port 146. Hose adapter 190 may include more or less protrusions 196, passages 197, and steps 198 depending on the application.

[0135] The second interface 194 may be configured to be releasably coupled to the hose 166. For example, as illustrated in FIG. 12B, the second interface 194 may include a plurality of axially extending fingers 199 for gripping the hose 166. The fingers 199 may be configured to grip a collar 201 of the hose 166. For example, a distal end of the fingers 199 may engage a trailing edge or shoulder 203 of the collar 201 to secure the hose 166 to the hose adapter 190. The fingers 199 may be resilient and may deform during connection and disconnection of the hose 166 to the hose adapter 190. As illustrated in FIG. 12B, the fingers 199 curve inwardly toward the centerline of the hose adapter 190 near the distal end of the fingers 199 to facilitate engagement of the fingers 199 with the trailing edge or shoulder 203 of the collar 201.

[0136] To couple an air source to the patient transfer system 100, a user may rotationally align one or more protrusions 196 of the hose adapter 190 with corresponding passages 197 in the fill port 146. The user may axially move the hose adapter 190 toward the fill port 146 such that the protrusions 196 slide through the passages 197, and then the user may rotate the hose adapter 190 relative to the fill port 146 to move the protrusions 196 behind one or more shoulders 198 of the fill port 146, coupling the hose adapter 190 to the fill port 146. To couple the hose 166 to the hose adapter 190, a user may insert a distal end of the hose 166 into the second interface 194 of the hose adapter 190 until the resilient fingers 199 snap behind the collar 201 of the hose 166, coupling the hose 166 to the hose adapter 190. The user may generally reverse these steps and remove the hose 166 from the fill port 146 .

[0137] (How to use) A suitable method for using the patient transport system 100 includes transporting a patient or other person's body 200 across one or more surfaces 210 on an air-bearing support device 101, deflating one or more inflated sections 104, 106, 114 of the support device 101 positioned at least partially under the patient, and laterally separating at least the first section 104 and the second section 106 of the device 101 and at least partially removing the device 101 from under the patient, e.g., without manipulating the patient's torso region or rolling the patient onto his or her side. A suitable method may also include inflating one or more deflated sections 104, 106, 144 of the patient transfer device or apparatus 101 positioned under the patient 200 prior to the at least partially deflating, and sliding the inflated device 101 and patient from one surface 210 to another.

[0138] More generally, the method application includes one or more of placing a body 200 on an air-bearing support 101 having first and second longitudinal sections 104, 106 attached along a selectively engageable or releasable joint 118, and inflating the air-bearing support 101 via an inlet or port 146 in flow communication with the first and second longitudinal sections 104, 106, on which the body 200 is supported on its upper surface 130. Transferring the body 200 across one or more surfaces 210 can be accomplished with the body 200 and air-bearing device 101 supported at least in part by airflow directed through a plurality of openings 152 on a bottom surface 150 of the air-bearing support 101 opposite the upper surface 130.

[0139] A preferred method also includes, for example, severing the longitudinal sections 104, 106 at the proximal end 108 of the air-bearing support 101 in the head region of the patient's 200 body, and separating the longitudinal sections 104, 106 along a selectively engaged seam 118 from the proximal end 108 of the air-bearing support through a middle portion 110 under the patient's torso to a distal end 112 or 113 disposed under the patient's lower leg or foot. Removal of the longitudinal sections 104, 106 can then be performed on the opposite side of the patient's 200 body without further manipulation, such as rotation of the torso portion.

[0140] The method may be performed by supporting a head region of the body 200 on or adjacent the proximal end 108 of the air-bearing support 101 and supporting a torso region 200 of the body within an intermediate region 110 of the air-bearing support 101, for example as defined between the proximal 108 and distal ends 112, 113, and the air-bearing support 101 being inflated to transfer the body 200 across one or more surfaces 210. Removing the air-bearing support 101 from beneath the torso region of the body may then be performed without further manipulation of the patient, for example the air-bearing support 101 being deflated following transferring the body 200 across the one or more surfaces 210.

[0141] Additional method steps include strapping the body 200 to the air-bearing support 101, e.g., the body 200 is secured to the top surface 130 using one or more adjustable straps 122 and adjustable couplings 126, for transferring the body 200 across one or more surfaces 210. The transfer can be accomplished by a caregiver or other operator pulling on one or more handles 142 disposed around the periphery of the air-bearing support 101, e.g., the body 200 is transferred across one or more surfaces 210 while supported on airflow as directed from an interior of the at least partially inflated support 101 through a plurality of openings 12 on the bottom surface 150.

[0142] More generally, a "use" of the system 100 may refer to a single transfer of a patient on the patient support 101 from one surface to another, or across different surfaces in two or more transfer procedures. For example, the same patient support 101 may be used to move a patient from a bed or stretcher to an examination or operating table for a medical procedure, and then after the procedure, to move the patient from the table to the bed or stretcher, at which point the sections 104, 106 can be separated and the device 101 removed. Alternatively, the support 101 may be used in multiple transfers before removal, such as from a hospital bed to a stretcher for transport to an operating table, and then from the operating table back to the stretcher, at which point the sections 104, 106 are detached for removal.

[0143] (Example) In a first embodiment, the transfer system may include an air-bearing support having first and second longitudinal sections, a port in flow communication with the first and second longitudinal sections, the port configured for inflation of the air-bearing support for transfer of a body thereon, and a selective coupling extending between the first and second longitudinal sections, the selective coupling configured to attach the first and second longitudinal sections together for transfer of a body on the air-bearing support and to at least partially decouple the first and second longitudinal sections for separation and removal thereof.

[0144] The selective coupling of the first embodiment may comprise a selectively releasable seam extending between the longitudinal sections from a proximal end of the air-bearing support toward a distal end of the air-bearing support, the releasable seam being configured to separate the longitudinal sections at the proximal end and separate the longitudinal sections from the proximal end toward the distal end. The releasable seam may be configured to maintain attachment of the longitudinal sections for body displacement upon inflation of the air-bearing support and to separate the longitudinal sections at the proximal end upon deflation of the air-bearing support and application of a manual force. The selective coupling may be configured for separation of the longitudinal sections at the proximal end, separation of the longitudinal sections to opposite sides of the body along the releasable seam, and removal of the air-bearing support from beneath the body without substantial further manipulation. The selective coupling may extend over substantially the complete longitudinal extent of the air-bearing support for separation and removal of the longitudinal sections as separate and independent components.

[0145] The transfer system of the first embodiment may further comprise a lateral section of the air-bearing support in flow communication with the first and second longitudinal sections, the selective coupling extending between the first and second longitudinal sections to a central portion of the lateral section for removal of the lateral sections together and the first and second longitudinal sections as a unit. A port may be disposed within the lateral section of the air-bearing support, thereby providing flow communication with the first and second longitudinal sections.

[0146] The port of the first embodiment may include an inlet coupling for an external air source configured for inflation of the air-bearing support. The relocation system may further include an air hose attached to the inlet coupling, the air hose adapted to direct an air flow from the external air source to the air-bearing support in a single use application of the relocation system. The air hose may include a collapsible flow section adapted to direct the air flow, the collapsible flow section configured for substantially flat storage in combination with the air-bearing support and extension from the air-bearing support for inflation thereof.

[0147] The transfer system of the first embodiment may further include an integral air supply coupled to the port, the integral air supply adapted for inflation of the air-bearing support in a single use application of the transfer system.

[0148] The selective joint of the first embodiment may include a longitudinal seam structure configured to define a substantially continuous upper surface of the air-bearing support spanning the selective joint between the first and second longitudinal sections, such that the body is supported on the substantially continuous upper surface upon inflation of the air-bearing support.

[0149] The transfer system of the first embodiment may further comprise a plurality of baffles disposed within one or both of the first and second longitudinal sections, the baffles extending vertically between the bottom and top surfaces of the air-bearing support to provide structural integrity upon inflation thereof. The baffles may extend across or transversely to the longitudinal sections, and the system may further comprise one or more ports or openings adapted to permit longitudinal airflow across the baffles upon inflation of the air-bearing support. The baffles may extend longitudinally along or longitudinally to the longitudinal sections, and the system may further comprise lateral sections in flow communication with the longitudinal sections for inflation thereof.

[0150] The selective coupling of the first embodiment may include a severable seam configured for separation and removal of the first and second longitudinal sections in response to a single-use transfer application of the air-bearing support, the system being configured for subsequent sanitary disposal. The severable seam defines a vertical web extending between the first and second longitudinal sections, and the system may further include one or more ports or openings disposed along the severable seam and configured for lateral airflow between the first and second longitudinal sections upon inflation of the air-bearing support.

[0151] The selective bond of the first example may include a perforated seam defined between the first and second longitudinal sections, the first and second longitudinal sections and the perforated seam being formed from the same substantially continuous material.

[0152] The transfer system of the first embodiment may further include a plurality of flow openings disposed on a bottom surface of the air-bearing support, the plurality of openings being configured for airflow between the air-bearing support and one or more surfaces across which body transfer is performed.

[0153] The transfer system of the first embodiment may further include one or more straps extending laterally across the first and second longitudinal sections of the air-bearing support, the one or more straps configured to secure the body to the air-bearing support during transfer.

[0154] The transfer system of the first embodiment may include one or more handles disposed along a periphery of the air-bearing support, the one or more handles configured to pull the air-bearing support to effect the transfer.

[0155] The air-bearing support of the first embodiment may include a proximal portion configured to support a head region of the body, an intermediate portion configured to support a torso region of the body, and a distal portion configured to support a lower region of the body.
