The invention relates to the field of patient care, specifically an apparatus and method for accommodating a patient or user to lay in a prone position, thereby improving their respiratory function and assisting in the recovery of a respiratory illness or condition.
When a patient who is suffering from acute respiratory distress caused by any number of factors including pneumonia, influenza, coronavirus, asthma, COPD or a physical trauma is brought in for medical treatment, the patient is most often laid down in the supine position while the treatment is being administered. Specifically, the patient is laid on their back in order to be treated or intubated so that their breathing may assisted or controlled by a mechanical ventilator. However, because gravity often directs fluid being collected within the patient's lungs back towards the dorsal region of the patient, the patient can often have great difficulty in breathing even with the assistance of a mechanical ventilator.
As has long been known in the medical field, patients suffering from acute respiratory distress who fail to improve after being placed on a ventilator are often rotated into the prone position. The reversal from lying on their back to lying on their stomach reverses the flow of fluid through their lungs which in turn relieves pressure and improves the patient's ability to breathe, even without a ventilator. In some instances, the patient may begin to feel relief in as little as a few minutes after being moved into the prone position.
While laying a patient down in the prone position is not typically a problem when done in a hospital or other medical care facility, a problem develops however when these facilities become overwhelmed and do not have enough beds or ventilators to meet the current patient demand. Additionally, for patients who remain conscious, it can be difficult or uncomfortable for them to lie in the prone position for extended periods of time on a substantially flat surface such a bed or gurney, particularly if they are elderly or otherwise physically compromised such as being overweight or having a larger than average chest. Finally, while laying prone in general enhances the patient's ability to breathe, this ability can be further improved by keeping the patient's chest and abdomen slightly off of the surface they are currently laying on, thereby further reducing the pressure placed on their already compromised respiratory system.
One possible solution to these issues has been to place pillows under the patient, however standard pillows are ill suited to support a patient in a prone position without requiring the patient to also turn their neck to either side, thereby altering the orientation of their oral airway. Additionally, in order for the patient's hips and shoulders to be supported and thus raise the patient's chest and abdomen slightly off the bed, several pillows would be required and would thus require more resources from the hospital or medical care facility, let alone full body support, and taking up too much room in an already small bed, cot, or gurney.
Other solutions have been to place other objects such as towels or other soft malleable items underneath the patient, thereby propping up the patient at the positions where those items are placed. However many of these objects lack sufficient rigidly and can often deform after prolonged use, thereby requiring frequent adjustment and repositioning by a health care worker.
What is needed is a physical support which is easy and simple to use which accommodates a patient in the prone position and which lifts or maintains the chest and abdominal regions of the patient off the surface they are laying on. The support should also sufficiently rigid so that it does not lose its shape over time. Additionally, the support should be compatible with pre-existing items that the health care provider may already possess, thereby reducing the overall cost of the support and allowing those pre-existing items to be used for other purposes when the support is not in use. Ideally, this support or pillow would just become laundry when disassembled, requiring no extra or specialized storage of the device.
An apparatus for maintaining a patient in a prone position while maintaining access to an oral airway of the patient. The apparatus includes a body portion, a first plurality of inserts, and a second plurality of inserts. In one embodiment, the first plurality of inserts has a smaller size relative to the second plurality of inserts. The apparatus also includes a means for forming a partition along a length of the body portion. Each of the first plurality of inserts and the second plurality of inserts can be moved independently of one another within the body portion to a position determined by the user.
In one embodiment, the body portion is defined by at least two segments, wherein each of the segments can accommodate at least one of the first plurality of inserts and at least one of the second plurality of inserts therein. In this embodiment the means for forming the partition along a length of the body portion also includes a means for dividing each of the at least two segments into an upper portion and a lower portion. At least one of the first plurality of inserts is disposed within the lower portion of each segment while at least one of the second plurality of inserts is in turn disposed within the upper portion of each segment.
In a separate embodiment, the upper portion of each segment is configured to be independently adjustable relative to each other, while the lower portion of each segment is configured to be independently adjustable relative to each other.
In another embodiment, the body portion of the apparatus has an opening communicated to the two segments of the body portion.
In yet another embodiment, each of the at least two segments include a coupling means that is disposed along at least a portion of their respective longitudinal lengths.
In another embodiment, the means for forming a partition along a length of the body portion includes at least one tapered width portion that is disposed along the respective lengths for each segment of the body portion.
In a related embodiment, the means for forming a partition along a length of the body portion includes a means for coupling the at least two segments of the body portion together.
In yet another related embodiment, the means for forming a partition along a length of the body portion includes a knot that joins the two segments to each other.
In a further embodiment, each of the segments of the body portion have a distal end, each distal end including a means for coupling the at least two segments together.
In yet another embodiment, that apparatus further provides a user the ability to adjust the relative position of the partition along the length of the body portion.
The invention further provides a method for maintaining a patient in a prone position while maintaining access to an oral airway of the patient. The method includes providing a body portion, inserting a first plurality of inserts into the body portion, and then forming a partition along a length of the body portion. Next, a second plurality of inserts is inserted into the body portion, wherein the first plurality of inserts has a smaller size relative to the second plurality of inserts. Finally, a position associated with each of the first plurality of inserts is manipulated or adjusted relative to each the second plurality of inserts within the body portion.
In one embodiment, inserting the first plurality of inserts into the body portion specifically includes inserting at least one of the first plurality of inserts into each of at least two segments defining the body portion, while inserting the second plurality of inserts into the body portion specifically includes inserting at least one of the second plurality of inserts into each of the at least two segments.
In a related embodiment, forming the partition along a length of the body portion further includes dividing each of the at least two segments into an upper portion and a lower portion.
In another embodiment, adjusting the position associated with each of the first plurality of inserts relative to the second plurality of inserts within the body portion also includes adjusting a relative position associated with the upper portion of each of the two segments in order to support the chest and hips of the patient. Alternatively, adjusting a relative position associated with the lower portion of each of the two segments in order to support the head and neck of the patient.
In one embodiment, inserting the first plurality of inserts into the body portion specifically includes disposing at least one of the first plurality of inserts into an upper portion of the body and then sealing the upper portion around the at least one of the first plurality inserts. Next, one of the second plurality of inserts is inserted into the body portion by disposing at least one of the second plurality of inserts into a lower portion of the body and then sealing the lower portion around the at least one of the second plurality of inserts. More specifically, the sealing of the upper portion around one of the first plurality of inserts is done by coupling a pair of lateral edges of the upper portion to each other with one of the first plurality of inserts disposed therein. Similarly, the sealing of the lower portion around one of the second plurality of inserts is done by coupling a pair of lateral edges of the lower portion to each other with one of the second plurality of inserts disposed therein.
In another embodiment, the partition is formed along a length of the body portion further by coupling the at least two segments defining the body portion to each other.
In an additional embodiment, the method also includes coupling a distal end of each of the at least two segments defining the body portion to each other.

The support 10 also comprises a plurality of inserts, specifically a plurality of small inserts 14 and a plurality of large inserts 16. Both the small inserts 14 and the large inserts 16 comprise a substantially cylindrical cross section, however each of the small inserts 14 comprise a smaller diameter relative to the large inserts 16. Each of the plurality of inserts 14, 16 are comprised of soft yet durable material such as cotton, foam, polyester fabric, or other similar materials or blends of materials now known or later devised. Additionally, each insert 14, 16 is preferably formed by rolling a segment of material or fabric similar to what is used in common bath towels into a substantially cylindrical or rolled shape, however in other alternative embodiments each insert may be comprised of a single pre-formed shape such as a sphere or ball, a rectangular prism or brick shape, a cube or square box, or any other suitable geometric shape. In one embodiment, the plurality of inserts 14, 16 may be exclusive to only being used in conjunction with the body portion 12 of the support 10, however in a preferred embodiment, the inserts 14, 16 are each comprised of a rolled absorbent material or fabric. Specifically, the inserts 14, 16 may be used as a separate cleaning or bathing item such as a towel, washcloth, or a cleaning shammy or wipe. The plurality of inserts 14, 16 are washable and reusable, thereby allowing the user to use at least a portion of the support 10 for other purposes when not otherwise being specifically used to support a patient while lying the prone position.
To use the support 10, a user begins by gripping the proximal portion of the body 12 and pulling it apart, thereby actuating the opening 18 as seen in

While the figures discussed above explicitly show four inserts being inserted into the body 12 of the support 10, specifically two small inserts 14 and two large inserts 16, this is meant to be for illustrative purposes only. Fewer or additional small or large inserts 14, 16, or inserts of a different size not explicitly shown, may also be used without departing from the original spirit and scope of the invention. Additionally, while it is disclosed that the small inserts 14 are first inserted into each segment 24 followed by a large insert 16, it is also expressly contemplated that additional or different sequences of inserts may be used in order to provide a support 10 for each unique patient.
Once the plurality of inserts 14, 16 have been properly positioned or adjusted within either the lower portions 20 or upper portions 22 of each respective segment 24, the user as seen in
Next, as seen in
When the support 10 is no longer needed, the large inserts 16 are removed from the body 12 by pulling each large insert 16 proximally out of the opening 18. The partition 26 between the lower portions 20 and the upper portions 22 is removed by removing the tightening or clamping means disposed thereon, or by simply untwisting the partition 26. The small inserts 14 are then pulled or moved proximally through each respective segment 24 and then removed from the body 12 through the opening 18. The small and large inserts 14, 16 may then be washed, stored, or used for other purposes, while the body 12 may also be washed and/or folded into a compact configuration and stored. The support 10 may be used again for another patient by reinserting at least some of the plurality of inserts 14, 16 as discussed above and once again placed on a flat surface.

In a related embodiment, the partition 26′ may be a permanent feature of the body 12′ of the support 10′. For example, the partition 26′ may comprise a strap, a snap, or a fastener 44 which allows the user to form or create the partition 26′ without first having to rotate or twist the lower portions 20 relative to the upper portions 22 of the body 12. Additionally, the body 12′ may comprise segments 24′ which each comprise a tapered width or substantial funnel shape or portion 46 that are integrally formed together so as to form a natural partition 26′ between the lower portions 20′ and the upper portions 22′. The combination of an integral partition 26′ with dedicated fasteners 44 allows the patient 30 or health care worker to quickly and easily divide the lower portions 20′ from the upper portions 22′ and thus provide proper upper and lower body support, respectively. The body 12′ is further comprised of a material or cloth which is washable and reusable, thereby allowing multiple patients 30 to use the support 10′.

Therefore, it must be understood that the illustrated embodiment has been set forth only for the purposes of example and that it should not be taken as limiting the embodiments as defined by the following embodiments and its various embodiments.
Therefore, it must be understood that the illustrated embodiment has been set forth only for the purposes of example and that it should not be taken as limiting the embodiments as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the embodiments includes other combinations of fewer, more or different elements, which are disclosed in above even when not initially claimed in such combinations. A teaching that two elements are combined in a claimed combination is further to be understood as also allowing for a claimed combination in which the two elements are not combined with each other, but may be used alone or combined in other combinations. The excision of any disclosed element of the embodiments is explicitly contemplated as within the scope of the embodiments.
The words used in this specification to describe the various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use in a claim must be understood as being generic to all possible meanings supported by the specification and by the word itself.
The definitions of the words or elements of the following claims are, therefore, defined in this specification to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or that a single element may be substituted for two or more elements in a claim. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements.
The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptionally equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the embodiments.
