Definitions
- the present invention generally relates to patient transfer devices and, more particularly to a single patient, personal use patient transfer apparatus which employs an air bearing to facilitate the transfer.
- Patient handling mattresses are known in the art which include at least two flexible material sheets, that together define a plenum chamber, with at least one sheet being perforated with small pinholes over at least a central surface area, and which open up directly to the interior of the plenum chamber.
- Such prior art mattresses are used by arranging the perforated sheet so that it faces an underlying fixed, generally planar support surface, such as a floor or table.
- the escape of air under pressure through the pinholes acts initially to jack a load placed upon the mattress above the perforated flexible sheet, and thereby creates an air bearing of relatively small height between the underlying fixed, generally planar support surface and the perforated flexible sheet.
- an air pallet is disclosed that is formed from upper and lower thin flexible film sheets sealed at their edges to form a plenum chamber.
- Wegener's air pallet functions to move a load with minimal friction over an underlying generally planar fixed support surface.
- the bottom thin flexible material sheet is perforated by small diameter perforations such as pin holes at the load imprint area.
- U. S. Patent No. 5,561 ,873 issued to Weedling, provides an inflatable flexible pallet within which an array of structurally interrelated inflatable chambers are formed to support a load when inflated.
- the flexible pallet is configured to resist lateral and longitudinal shrinkage of the load support surface, as well as ballooning and hot dogging. Rotational instability is also reduced by providing a greater load surface support area.
- an inflatable medical patient transfer apparatus that has a combination of transverse partition members and a raised perimeter section to reduce deleterious ballooning and uneven inflation as well as quick emergency deflation. Additional differentially inflatable patient rolling chambers are disclosed on the top of the transfer apparatus to provide assistance to medical personnel in beginning to roll patients reclining or lying upon the transfer apparatus, particularly in a deflated condition on a hospital bed. [0006] All of the foregoing devices have needed to be cleaned after each use so as to prevent transmission of disease from their patient engaging surfaces, since they are all intended for multiple uses with multiple patients.
- Reusable mattresses need to have the material on their outer surfaces that contacts the patient be readily washable, and also be non-absorbent, since patients often experience loss of bodily fluids. None of the foregoing prior art transfer mattresses are appropriate for assuring single use by and personal to a single patient since all are susceptible to some cleaning that would mask the fact that there had been a prior use with the same or different patient. In the medical field, there is a continuing need to easily, safely and comfortably transport an injured person, hospital patient or injured person at the scene of an accident, using an air mattress that is not only suitable for only a single use, by a single patient, but also retains some evidence of that use so as to alert a second user to the mattresses "previously used" status.
- the present invention provides a transfer mattress adapted for single use by and personal to a single patient including a single use top panel having a width, a length, and longitudinally oriented peripheral edges and a single use bottom panel having the same width, the same length, longitudinally oriented peripheral edges and a plurality of perforations.
- the longitudinally oriented peripheral edges of the single use top and bottom panels are sealingly fastened often by heat sealing, stitching, or adhesives.
- Each panel may be formed, at least in part, from a cold water insoluble, hot water soluble and/or dispersible, disposable film or fabrics formed from a miscible polymeric resin blend.
- the panels comprise a cold water soluble partially hydrolyzed polyvinyl alcohol, cold water insoluble hot water disintegrable aliphatic polyester, and minor proportions of processing and performance aids.
- the aliphatic polyester has a melt temperature, i.e., a liquid soluble temperature, above the normal body temperature of a human (37 degrees C; 98.6 degrees F.) and is present in the resin blend at a concentration sufficient to constitute the continuous phase of the blend, with the polyvinyl alcohol constituting a discontinuous phase of the blend.
- the aliphatic polyester renders the resin blend, and the partially hydrolyzed polyvinyl alcohol in the blend is, cold water insoluble and determines the temperature at which articles formed from the blend will be subject to dissolution in an aqueous bath and subsequent disposal.
- a plurality of baffles are attached to an inner surface of the single use top panel and an inner surface of the single use bottom panel so as to be transversely oriented between the top sheet and the bottom.
- the baffles along with the widths of the top and bottom panels define a radially-outwardly curved perimeter wall that is disposed between an edge of the baffles and the sealed peripheral edges of the top and bottom panels.
- a single patient, personal use transfer mattress having a top panel having a width, a length, and longitudinally oriented peripheral edges and a bottom panel having the width, the length, and longitudinally oriented peripheral edges and a plurality of perforations. At least a portion of the longitudinally oriented peripheral edges of the top and bottom panels are joined together with a cold water insoluble, hot water soluble and/or dispersible, disposable material formed from a miscible polymeric resin blend.
- a single use mattress in yet another embodiment, includes a top panel having a width, a length, and longitudinally oriented peripheral edges and a bottom panel having the same width, the same length, longitudinally oriented peripheral edges and a plurality of perforations.
- the longitudinally oriented peripheral edges of the top and bottom panels are sewn together with a cold water insoluble, hot water disintegrable aliphatic polyester thread, and are formed from a panel of nylon twill or the like insoluble material.
- the aliphatic polyester thread has a liquid soluble temperature above a normal human body temperature and is present in a resin blend at a concentration sufficient to constitute the continuous phase of the blend, with the polyvinyl alcohol constituting a discontinuous phase of the blend so that the aliphatic polyester renders the resin blend, and the partially hydrolyzed polyvinyl alcohol in the blend cold water insoluble and determines the temperature at which articles formed from the blend will be subject to dissolution in an aqueous bath and subsequent disposal.

- a single patient, personal use transfer mattress 2 formed in accordance with one embodiment of the present invention comprises a top panel 4, a bottom panel 6, and a plurality of baffle-panels 8. More particularly, top panel 4 comprises a head portion 12, a foot portion 14, and a peripheral edge 16, and is formed from a sheet of often stainable fabric, i.e., a woven or entangled mass of fibers, or a film that is highly susceptible to staining by, e.g., semi-solids and liquids, such as, blood, urine, feces, hospital strength disinfecting compounds, alcohol, or the like on outer surface fibers or coatings 20. In some embodiments, nylon twill may be used with adequate results.
- a sheet of often stainable fabric i.e., a woven or entangled mass of fibers, or a film that is highly susceptible to staining by, e.g., semi-solids and liquids, such as, blood, urine, feces, hospital strength disinfecting compounds, alcohol
- fibers for forming top panel 4 or threads 5 used to sew top panel 4 to other portions of transfer mattress 2 may be at lease partially made or formed from a cold water insoluble, hot water soluble and/or dispersible, disposable film or fabrics formed from a miscible polymeric resin blend.
- such panels or threads 5 may, for example, comprise a cold water soluble partially hydrolyzed polyvinyl alcohol, cold water insoluble hot water disintegrable aliphatic polyester, and minor proportions of processing and performance aids.
- the aliphatic polyester has a melt or liquid soluble temperature above the normal body temperature of a human (37 degrees C; 98.6 degrees F.) and is present in the resin blend at a concentration sufficient to constitute the continuous phase of the blend, with the polyvinyl alcohol constituting a discontinuous phase of the blend.
- the aliphatic polyester renders the resin blend, and the partially hydrolyzed polyvinyl alcohol in the blend is, cold water insoluble and determines the temperature at which articles formed from the blend will be subject to dissolution in an aqueous bath and subsequent disposal.
- transfer mattresses 2 not only retains a stained and discolored appearance for longer periods of time after use thereby alerting hospital staff or other care givers that a particular transfer mattress 2 has completed its useful life, and must be discarded, but also if an attempt is made to launder the mattress after a single use either top panel 4, bottom panel 6 or soluble threads 5 (Fig. 8) that are used to sew them together disintegrate during the washing process.
- Bottom panel 6 comprises a head portion 22, a foot portion 24, and a peripheral edge 26, that is also formed from fibers comprising any of the foregoing substantially permanently stainable materials.
- An inlet opening 32 is formed in a corner portion of transfer mattress 2, and may be a closable opening that sealingly accepts an air supply hose 34.
- Inlet opening 32 is sized and shaped so that air supply hose 34 may be inserted, with the inlet being thereafter snapped shut or otherwise closed to hold air supply hose 34 in place while transfer mattress 2 is being inflated.
- Inlet opening 32 may also include a valve (not shown) that is biased to be normally closed to prevent air from exiting through the inlet, and opened when air supply hose 34 is inserted into inlet opening 32.
- Bottom panel 6 also includes a plurality of tiny holes 36 that are defined through its thickness to allow air, that is supplied by a low-pressure air supply to transfer mattress 2, via air supply hose 34, to escape in a controlled manner.
- the air supplied to transfer mattress 2 escapes through plurality of holes 36, providing a weight-bearing cushion of air that facilitates the sliding of transfer mattress 2 along a surface, as well as, from one surface to another.
- Plurality of baffle-panels 8 each comprise substantially rectangular sheets comprising any of the foregoing substantially permanently stainable materials, and include a top edge 40 and a bottom edge 42.
- Baffle-panels 8 may have differing widths, depending upon their position within transfer mattress 2.
- Each top edge 40 is fastened, e.g., stitched with soluble thread, transversely to a portion of inner surface 19 of top panel 4, and each bottom edge 42 is fastened, e.g., stitched with soluble thread 5, transversely to a portion of inner surface 29 of bottom panel 6, as will hereinafter be disclosed in further detail.
- a single patient, personal use transfer mattress 2 is assembled according to the present invention in the following manner.
- Bottom panel 6 is laid out on a suitable support surface so that baffle-panel 8 may be transversely arranged in the center section of inner surface 29. Once in this position, bottom edge 42 of each baffle-panel 8 is fixedly fastened to inner surface 29 of bottom panel 6.
- Baffle-panels 8 are often heat sealed, sewn, glued, or otherwise bonded together along the interface between bottom edge 42 and inner surface 29 of bottom panel 6.
- top panel 4 and bottom panel 6 are not formed from soluble materials as disclosed hereinabove, they may be sewn together or glued with materials that are soluble. Heat sealing may be done with the application of heat or ultra sonic energy at the edge interface.
- an interface structure (Fig. 6) is formed between top edge 16 and bottom edge 26 so as to form a bond that is resistant to rupture under normal loading for a short period of time, i.e., approximately twenty-four to thirty-six hours.
- top panel 4 and bottom panel 6 are formed from a nylon twill or the like insoluble material, and sewn together with a cold water insoluble, hot water disintegrable aliphatic polyester thread 5, the nylon twill panels will simply separate when laundered (Fig. 8).
- top panel 4 is arranged in overlying confronting relation with bottom panel 6 so that head portion 12 of top panel 4 is confronting head portion 22 of bottom panel 6 and foot portion 14 of top panel 4 is confronting foot portion 24 of bottom panel 6.
- each top edge 40 of each baffle-panel 8 is fixedly fastened to inner surface 29 of top panel 4.
- a pair of substantially parallel peripheral pontoons 35, located at the ends of transverse baffle-panels 8 provides a slight relative restriction to air passing to the central chambers during inflation, thereby decreasing the tendency of the device to "balloon", i.e., where the load is jacked or raised up so high that it becomes unbalanced on the footprint formed by the central portion of mattress 2.
- Pontoons 35 also provide for efficient feeding of low-pressure air to all the central chambers defined by baffle-panels 8 at once, effectively encouraging more uniform inflation of those central chambers, even while slightly restricting or slowing down the feeding of air to them.
- Pontoons 35 also provide enhanced stiffness to the entire transfer mattress, making it easier to handle when inflated. Thus forming pontoon 35 according to this relationship provides for significantly improved sliding movement of transfer mattress 2 during use.
