(1) Field of the invention
This invention relates to accessories and equipment used by medical personnel and caregivers in the handling of bedridden patients. Bedridden patients are often immobile and may be at risk for the forming of pressure sores or ulcers on their body. Pressure on a patient's skin, during extended periods of time, may cause pressure ulcers in areas where bone or cartilage is in very close proximity to the surface of the patient's skin.
One effective way to combat pressure ulcers or discomfort to a bedridden patient is to frequently turn the patient, along the patient's general linear body axis, so that the patient may be rotated. The rotations serve to assist the patient in resting on one side or the other, for short stretches of time. Specially-shaped pillows and contoured, flexible wedges are utilized on hospital mattresses to help in relieving some of the pressure of different body sections against the mattress. Pillows that are stuffed partially under the patient are often used to support the patient's upper body when resting on their left or right sides.
Turning patients can be difficult and time consuming for hospital staff or a caregiver, and frequently involves the coordination of two or more persons. Turning a patient can result in discomfort or injury to the patient, as well as to caregivers from pushing and pulling the patient's weight during turning maneuvers. Additionally, the pillows or wedges used in turning and supporting the patient are often non-uniform and can pose difficulty in achieving consistent turning angles, as well as occasionally slipping out from underneath the patient.
The disclosed body wedge 1 is intended to overcome the above-described limitations and difficulties, as it provides new features not hereto found in similar devices.
(2) Description of the Related Art, including information disclosed under 37 CFR 1.97 and 1.98. The following references describe materials and devices that have some similarity with regard to the intended functions available by means of use of Applicant's inventive concept:
U.S. Pat. No. 5,182,828; Feb. 2. 1993; Alivizatos; A machine washable wedge shaped support structure is formed from a fabric envelope loosely filled with lightweight, preferably polystyrene, beads which shape it. The fabric may have a non-skid surface to resist sliding in use. The wedge conforms to a patient's or infant's body. When compressed, the fabric envelope and beads lock into a roll-preventing support structure. One alternate version has a stabilizing panel extending from the pointed end of the wedge on which a patient lies. Another version has a connecting panel between two opposing triangular shaped wedges. It provides roil preventing support for a pregnant woman and doubles as an anti-roll pad for infants.
U.S. Pat. No. 7,240,384; Jul. 10, 2007; DuDonis; The patient positioning aid assists a caregiver in rotating and positioning immobile patients. Such patients require periodic movement to prevent the development of ulcers. Conventional methods use rolled blankets or pillows to support such patients. Such improvisations are often crushed by the patients, especially by bariatric patients. The present invention has a strong resilient foam core which resists compression by a patient, yet also has a yielding surface foam layer which avoids trauma to the patient's skin. The cover is removable for cleaning, waterproof, and utilizes an anti-slip, high friction coating on the bottom which resists sliding on the bed. In addition, handles on the caregiver side of the aid assist in the maneuvering of the aid to position it properly.
U.S. Pat. No. 9,381,107; Jul. 5, 2016; MacLeod; A post shoulder surgery rehabilitation apparatus in the form of a bed wedge having a shoulder support wedge structure attachment to provide the optimal support and comfort to a patient while resting or sleeping on a bed or similar structure. An exemplary embodiment of the bed wedge apparatus is capable of being inflated and deflated to the optimal angle for comfort and support for the repaired shoulder by means of a remote control switch by the patients themselves without assistance from a caregiver. Alternate embodiments of the bed wedge apparatus include ones without the need for inflation or deflation and ones that have shoulder support wedge structures for both shoulders after surgery.
U.S. Pat. No. 9,820,903; Nov. 21, 2017; Steffens, et al. A device for use with a bed having a frame and a supporting surface includes a flexible sheet with a tether strap connected to the sheet and extending from the sheet. The flexible sheet has opposed top and bottom surfaces, with the top surface having a high friction material with a higher coefficient of friction as compared to the bottom surface, which includes a low friction material. The tether strap is configured for connection to the frame of the bed to secure the sheet in place. A system incorporating the flexible sheet may also include an absorbent pad configured to be placed on the top surface of the sheet, where the high-friction top surface resists sliding of the absorbent pad, as well as one or more wedges having a base wall that the wedge rests on and a ramp surface configured to confront the sheet when the wedge is placed under the sheet. The base wall and the ramp surface may also contain high friction and low friction materials, respectively.
U.S. Pat. No. 7,171,710; Feb. 6, 2007; Mann; A system used for the prevention of positional plagiocephaly in which an infant receiving member includes an infant supporting surface, a first portion, and a second portion. An inclined member is positioned at least partially under the first portion of the infant receiving surface such that the first portion of the infant receiving surface is inclined.
The inventive concept disclosed is essentially a wedge type support cushion constructed in a specific shape and contour. The shape, contour, and other features of the body wedge 1 facilitate the proper positioning and re-positioning of a bedridden patient by one or more caregivers who make use of the patient body wedge 1. The disclosed patient body wedge 1 is intended, in static situations, to help support the upper and lower torso of the patient. A temporary static support positioning of the body wedge 1 will allow a patient to have a comfortable range of movement of his/her lower and upper extremities (dependent on the extent of the patient's injuries), thereby providing increased comfort and no interruption of the blood flow to various parts of the patient's anatomy.
A very important use of the patient body wedge 1 is to provide an effective mechanism whereby a patient's body may be repositioned in bed. A first body wedge 1 is arranged and deployed at least proximate the upper torso of the patient. A second patient body wedge 1 is used in coordination with the first body wedge 1 and may be positioned proximate the lower torso of the patient. Each of the patient body wedges 1 is constructed with a grip handle 24, which helps facilitate an efficient manner of maneuvering the body wedges 1 during movement or re-positioning the patient's body at certain time intervals, or moving the patient onto a different bed.
The objects, features, and advantages of the inventive concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling five figures, show the basic components and functions of embodiments and/or methods of use. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures.
The discussion of the present inventive concept will be initiated with
In essence,
The body wedge 1 construction features a rectangular-shaped, sloped front panel 3 and a rounded apex 2. The rounded apex 2 of the body wedge 1 is contoured so as to provide a gentler and more widely-distributed pressure area on the back or torso 32, 33 of a patient 31, when the patient 31 is lying on his/her side. This rounded apex 2 provides more comfort for patients 31, versus the normal orthogonal straight-edge found on most body wedges used for patient care. Such prior art straight-edges often serve to initiate the beginning of a pressure injury to the back of the patient 31. Two body wedges 28, 29 are illustrated providing support to a patient 31 in
To further provide patient 31 comfort, the left rear edge 7 and rear surface 21 (out of view) of the body wedge 1 are constructed with a higher than normal vertical dimension when the body wedge 1 is placed atop a mattress surface than prior art body wedges. For patient 31 comfort and stabilization of the torso of a patient 31, the optimum angle between the sloped front panel 3 and the planar base panel 22 is thirty degrees.
Further, it is an objective of this inventive concept that the feature off higher than normal ratio of the vertical dimension of the rear surface 21 relative to the surface of the mattress, coupled with the rounded apex 2, provide a structure that helps eliminate the possibility of a pressure injury being inflicted on the patient's 31 back.
A further objective of this inventive concept is to provide materials of fabrication that are sanitizable, such that caregivers or care facilities may cleanse the exterior materials to render them free from viruses, germs, soils, and provide the capability of re-using the patient body wedge 1.
The grip handle 24, in the preferred embodiment, attached to the base panel 22 at attachment points 17, as is more clearly depicted in
In
The identical triangular design contour, as described above, also exists for the right sidewall 16 (not in view). This symmetry thereby renders the left rear edge 7 and right rear edge 14 of the body wedge 1 parallel and mutually coextensive. Further, the front edge 4 of the base panel 22 and the base rear edge 11 of the base panel 22 are parallel and mutually coextensive. The base panel 22 comprises an inner surface and an outer surface. In the preferred embodiment, the sloped front panel 3 of the body wedge 1 is fabricated so as to be oriented at a thirty-degree angle from the plane of the base panel 22.
The left upper edge 5 of the left sidewall 9 is connected, by a seam 26, to the sloped front panel 3 (more readily seen in
In
Common patient care procedures using the body wedge 1 relate to methods for moving, turning, and/or positioning a patient 31 on a bed 40 or other supporting surface. The bed may include a frame and a mattress/sheet combination 36 supported by the frame.
As shown, the first body wedge 28 is placed at least proximate the upper torso 32, or upper body, of the patient 31, while the second body wedge 29 is placed proximate the lower torso 33, or lower body of the patient 31. Each wedge 28, 29 thereby has its base panel 22 (not in view) flat upon the mattress/sheet 36 combination, while each respective sloped front panel 3 is intrinsically positioned at an approximately thirty-degree angle from the plane of the mattress/sheet 36 combination.
The base panels 22 of the bed wedges 28, 29 are formed of a non-slip material 23 having a coefficient of friction which prevents sliding along the sheet/mattress 36 combination. Caregivers are able to maneuver both bed wedges 28, 29 efficiently by grasping the grip handle 24 of each respective bed wedge 28, 29. Use of the grip handles 24 enables a sure and speedy grasping of the both bed wedges 28,29, in order to place the bed wedges 28, 29 in appropriate locations to re-position the patient 31.
The arrangement presented in
The bed 40 of a patient 31 normally has a bedsheet covering a mattress, as shown in
To reposition the patient 31 to a posture of lying on his/her back, both wedges 28, 29 are removed, thereby allowing the patient 31 to lie fully on his/her back. To reposition the patient 31 so as to lie on the opposite side of the body, the preceding sequence is repeated, by turning the patient 31 on his/her back, then inserting each of the body wedges 28, 29 underneath the second edge 39 of the bedsheet.
