This application relates generally repositioning an individual in a bed. More particularly, this application relates to patient repositioning units having a frame and support bars that may be used to grip a flexible member such as a bed sheet, bed linen, draw sheet, sling, plastic sheet, or other flexible member placed under an individual, and facilitate movement or suspension of the individual on the flexible member by utilizing existing lift technology on a moveable bed or on the frame.
Immobility of a patient contributes greatly to the deterioration of patient health. Immobile patients are prone to bedsores and pneumonia. A bed sore can take months or years to heal depending on the severity and location of the sore. Pneumonia occurs in immobile patients because secretions pool in the lungs fostering bacterial growth. Generally side-to-side turns of such patients, approximately every two hours, can prevent many occurrences of bedsores and pneumonia. Additionally, side-to-side turns are necessary to accomplish examinations of the patient. However, turns of this nature are generally the responsibility of hospital nurses, orderlies, or other staff in similar types of facilities.
Additionally, patients require the head of the bed to be raised to facilitate breathing and increase comfort. As a result of this incline, patients tend to slide toward the foot of the bed, impeding a patient's normal breathing and digestive functions and resulting in patient discomfort.
When a patient is obese or larger than the staff member, the force required to properly reposition the patient is considerable. Consequently, multiple staff members are required to reposition the patient manually. Moreover, if additional staff members are unavailable, the lone staff member is susceptible to injuries while attempting to transfer or reposition the patient without either mechanical assistance or, additional staff labor.
Back injury is a common work injury of nurses and hospital staff generally as a result of moving overweight, obese or patients who are significantly larger than the staff member. The act of turning a patient from side to side precludes proper body mechanics for lifting. In addition, obesity in the United States is increasing in marked amounts. Patient weight increases will only exacerbate the rate of back injuries among nurses, and increase the number of workers compensation claims filed as a result of such injuries as well as reduce the number of able body hospital staff. Consequently, assistance is necessarily required to accomplish necessary patient movement as well as protect hospital staff members against injury proximately resulting from patient repositioning, turning and transference.
Moreover, the task of patient repositioning is labor intensive and time consuming. Generally, patient movement requires at least two staff members. Generally nurses are female and significantly smaller in stature and weight then the patients they are assigned to care for. Furthermore, hospitals and skilled nursing facilities are homes to patients weighing in excess of 250 pounds. Consequently, at least three staff members are sometimes required to reposition a patient of this size. With the increase of nursing and staffing shortages, it is frequently impossible to gather enough staff members to move a large or oversized patient. Thus, either patient care suffers or the risk of injury to staff members is greatly increased.
Another problem is money. Devices that incorporate machines, motors, and other complicated machinations to effectuate lift and other movement cost much more money than those that don't as well as incur more potential for civil liability should one of those machinations fail. Further, existing devices do not have a simple and effective means of gripping fabric, draw sheets, or standard hospital bed linens on which a patient is lying. Typically, devices such as that found in U.S. Pat. No. 5,890,238 to Votel are meant for patient transfer only at least because the gripping design is not designed for a caregiver to attach to linens.
Therefore a need exists for a functional, yet simple to operate, patient repositioning apparatus. Such an apparatus must be operational by one staff member without compromising patient safety and staff member safety; easy to install and operate as well as not consume scarce space in hospital or skilled nursing facility; must not compromise patient safety when effectuating the tasks of patient repositioning; can be used by a single caregiver to reposition a patient; is capable of easy attachment to linens for suspension of a person; and does not require expensive internal machinations to accomplish patient lift but uses existing lift technology on beds to accomplish suspension or movement of a patient.
This application describes and discloses a patient positioning apparatus including a base, a support column, at least one positioning arm on the support column capable of being positioned over a bed and having a buckle and strap capable of securing to a patient support connected to bed linens or other flexible member so that a patient can be partially or totally suspended when an adjustable bed is lowered or when the patient support is raised. The apparatus may further include a telescoping support column and horizontal support for supporting positioning arms. Patient repositioning may be effectuated by positioning the arms over a patient, extending straps with buckle inserts into receiving buckles on a patient support or support bar secured to bed linens. A patient positioning apparatus may be free-standing or may be mounted to a ceiling or a wall or may include a swiveling support column. A fabric gripper may be used to connect the flexible member to the apparatus.
These and other aspects of the present invention will become more fully apparent from the following description and appended claims.
The following description can be better understood in light of Figures, in which:
a is an elevated perspective view of an exemplary embodiment of a patient positioning apparatus;
a shows a detailed view of an exemplary embodiment of a hook and rod arrangement fastened to a support sheet;
Together with the following description, the Figures demonstrate and explain the principles of patient positioning systems and associated components and methods. In the Figures, the thickness and configuration of components may be exaggerated for clarity. The same reference numerals in different Figures represent the same component.
In the illustrated embodiments, aspects and features of patient repositioning systems and associated components and methods are disclosed and described below.
As shown in
One embodiment of a base portion includes one or more legs 3 capable of extending in opposite directions from either the anterior or posterior of support column 13. In some embodiments, legs 3 may telescope, as shown
Support column 13 may be constructed of powder-coated steel and may be 4 inches square, so as to withstand the weight of an individual 26 of any known weight, and suspended by arms 17. Retractable belt assemblies 21 may be coupled to positioning arms 17 using support tabs 16 (See,
In other embodiments, support column 13 may include additional columns. An outer column of the support column may swivel around an inner column with apertures. The outer column support, also having apertures, may be capable of aligning with those of the inner column by inserting the outer column over the inner column. In this way the swivel can be locked by inserting a locking pin through each of the inner and outer column support apertures. Other known manners of creating a swiveling column will be immediately recognized by those skilled in the art.
Most hospital beds are of a standard height. Because of the uniform height of hospital beds, a fixed height support column 13 may be effective in providing sufficient height to system 1. However, because some beds may vary in height and in the levels of vertical movement, some embodiments may also accommodate vertical movement of support column 13, or of the overall height of system 1.
To effectuate vertical movement of system 1, a crank assembly or a hydraulic assembly as described in related U.S. patent application Ser. No. 11/170,605 “Patient Mobility Apparatus” to White disclosed above may be incorporated into the present invention.
The repositioning structure coupled to support column 13 may be used for repositioning a patient 26 in bed 25. The position of the repositioning structure and associated structures such as arms 17 relative to bed 25 and the motor of bed 25 may be used together to repositioning a patient 26. For example, standard hospital beds typically come with an electric motor or other adjustable beds used to raise, lower, or otherwise place bed 25 in various positions. Taking advantage of this standard lifting and repositioning feature along with system 1 may allow for a single caregiver to easily reposition patient 26.
In some embodiments, such as those illustrated in
For example,
To change patients' bed linens, flexible member 33 may be placed underneath patient 26 and bed linens, or flexible member 33 may be the bottom-most layer of bed linens. Bed 25 may then be raised enough to allow for the insertion of the buckle inserts 24 into receiving buckles 29 on one side of flexible member 33. The dirty bed linens may then be loosened from one side of bed 25. By then lowering bed 25, patient 26 may roll to one side of bed 25, allowing removal of a portion of the dirty bed linens, and partial replacement with clean bed linens. Bed 25 may then be raised and buckle inserts 24 removed from receiving buckles 29 and flexible member 33 may be spread back onto the bed mattress. Once the dirty bed linens are rolled off of the mattress and next to patient 26, exposing a bare portion of the mattress on bed 25, the clean linens may be spread on the bare side of the mattress with the remaining clean linens rolled up next to the patient 26. Then, on the other side of bed, flexible member 33 may be similarly raised allowing the dirty linens to be removed from bed 25 and allowing the clean linens to cover the entire mattress. Bed 25 may then be lowered whereby patient 26 rolls onto the clean linen and over the remaining clean linen portion rolled next to patient 26. The bed may then be raised and buckle inserts 24 removed from flexible member 33. Therefore, the dirty linen may be finally removed and the clean linen can be pulled out from underneath the patient 26 and spread uniformly over the mattress.
In their simplest form, arms 17 may remain fixed and extend outward from support column 13, thereby allowing them to be positioned over patient 26 in bed 25. In one embodiment, as shown in
Once arm 17 is positioned over a patient 26, it may be secured to flexible member 33 through the use of a buckle assembly as describe above, and capable of supporting patient 26, and may be sufficiently strong to support any size and weight of patient 26. Because patients may be large and/or overweight, retractable straps with buckles using heavy duty nylon or canvas or other similar materials can be used to provide sufficient strength to support a patient of any weight. In some embodiments, retractable devices can be found in standard off-the-shelf seat belt units with heavy duty nylon webbing capable of supporting a person suspended by arms 17. McMaster-Carr retractable assemblies may provide acceptable standards of load to lift ratios. Seat belts of this type with release buttons on the buckle inserts similar to those used in automobiles and which can withstand inertial unlatching are common. (See, for example, U.S. Pat. No. 6,725,509 to Lee and its related references). Further, the receiving mechanism for the buckles can be attached to the support sheet, a gripper or other mechanism secured to the support sheet or in other embodiments those skilled in the art will immediately appreciate.
Some embodiments for securing support arms 17 to flexible member 33 may be to use a sling-type arrangement as shown in
In some embodiments, straps 23 of any durable material can be fixed, permanent or removable, to either the retractable belts 21 or the receiving buckles 29 that incorporate a traditional belt and buckle arrangement. Using this arrangement, straps 23 can be cinched to a desired length and tension. When not in use they can then be placed to the side of the bed. Furthermore, attachments to flexible member 33 need not be flexible straps but may also be of a more rigid construction.
Flexible members 33 may provide a stable, flexible, lifting platform on which to lift patients. Some exemplary flexible members 33 may be made of vinyl, nylon, canvas, bed sheets, draw sheets, mattress pads, or other materials or configuration sufficient to accomplish lifting a patient or a portion of a patient reposing on flexible member 33, as desired. In other embodiments, harnesses, slings, stretchers or other known suspension supports may also be used in and with the embodiments disclosed herein. Flexible members 33 may also incorporate buckles fastened to them using known techniques such as sewing heavy duty buckle ends to reinforced material and stitching onto the body of flexible member 33.
System 1 may be mounted in any number of ways that will not sacrifice its utility or overall design. For example,
In other embodiments, a detachable fabric gripper may be used as is shown in
In some embodiments, bottom bar 113 may have clamp support 117, which may attach to lower bar 113, and then extend towards top bar 111, where it may provide support for a receiving buckle 123 and clamp handle 119. Handle 119 may pivot on pin 125 that pivotally mounts to clamp support 117 and the receiving buckle 123. When closed, handle 119 extends over top bar 111 and engages wedge 121, thereby sealing bars 111, 113 together. Wedges 121 on the bars (beneath the handle flanges) may ensure a tight grip when handle 119 is closed. A slick material on the wedge 121 (e.g., Teflon) can be used to facilitate the closing of handle 119. Handle 119 may be long enough to provide sufficient leverage to wedge the bars 111113 closed.
On pivot pins 125, which support handles 119 and support clamps 117, buckles 123 may be similar to seat belt latches as described above, to receive buckle inserts 24 at the end of the retractable straps 23 on system 1. In some embodiments, a caregiver may fold a flexible member 33, such as a draw sheet of a hospital bed, to a desired position. Fabric gripper 110 may then be placed open on a bed next to the fold of the draw sheet. The fold of fabric may then be tucked into gripper 110, which is then closed. Handles 119 may then be moved to the closed position against wedge 121 to firmly grip flexible member 33 in place.
Handle 119 and wedge 121 arrangements may be in a simple, cost-effective gripping assembly, although other arrangements may be used. (e.g., spring biased mechanisms, manually locking mechanisms, toggle clamps, and etc. can also be used). For example, using the same bar arrangement as described above, toggle clamps can be used to allow for hinging, opening, closing, and locking the bars securely shut after a fabric sheet is placed between the two bars.
In other embodiments, such as those illustrated in
Support bar 220 may have a length sufficient to support an individual or a desired portion of an individual. For example, support bar 220 may be between about two and about seven feet long. In some embodiments, support bar 220 may be shorter to only support an upper or lower portion of an individual as needed. For example, system 1 may be used to suspend the legs of an individual, such that a shorter support bar 220 may be preferable to a longer support bar 220. Similarly, any of the devices described herein for attaching to flexible member 33 may be similarly arranged in length.
In some embodiments, resilient member 250 may be located in support bar 220. As shown in
In some embodiments, resilient member 250 may be attached to insert bar 230, or may be integral with insert bar 230. For example, as shown in
Insert bar 230 may be shaped such that it approximates the cross-sectional shape of internal space 228 of support bar 220 such that flexible member 33 is contacted and compressed between insert bar and support bar 220 at various points to prevent slippage or removal of flexible member 33 as a load is applied to flexible member 33, as described above with using system 1.
In some embodiments, fabric clamp 220 may provide structure such that when a load (as represented by arrow c in
In some embodiments, contact areas 229 may include a coating, surface finish, applied material, or other technique to provide a slip-resistant surface. For example, contact areas 229 may be coated with rubber, foam tape, or other applied material, or may have a rough surface from machining, rough sanding, or other manufacturing process. In some embodiments, the slip-resistant surface features may be applied to contact areas 229 of support bar 220, to corresponding regions of insert bar 230, to both support bar 220 and insert bar 230, or to any and all surfaces of support bar 220 and insert bar 230 that may contact flexible member 33.
Attachment members 240 may be coupled to support bar 220. In some embodiments, attachment members 240 may be pivotably coupled to upper flange 227 of support bar 220 using fasteners 242, such as rivets, bolts, wave washers, springs, or using any known techniques, or may be fixed to support bar 220 by welding, fasteners, etc., or may be integral with support bar 220. Attachment members 240 may be buckles, such as seat belt buckles, as shown in
In some embodiments, flexible member 33 may be placed in fabric gripper 210 by laying a portion of flexible member 33 over opening 222, placing insert bar 230 into internal space 228 of support bar 220 such that resilient member 250 compresses, thereby trapping a portion of flexible member 33 between insert bar 230 and support bar 220. Flexible member 33 may be removed from fabric gripper 210 by pulling a portion of flexible member 33 extending past flange 224 downward such that resilient member 250 is compressed and the top portion of insert bar 230 moves past flange 226, allowing insert bar 230 to rotate out through opening 222, freeing flexible member 33.
