Definitions
- the present invention relates to a patient support device. More particularly, the present invention relates to a patient support mattress with a lower extremity raiser, which may be useful for raising and supporting the buttocks, upper legs, knees, and/or lower legs of obese patients for the purpose of providing medical treatment to the hips, legs, and feet.
- Patient support devices including patient transfer mattresses, have an inflatable plenum that provides an air cushion to lifts and support a patient laying on a bed or other support surface.
- Some contemporary examples of patient transfer mattresses are disclosed in U.S. Pat. No. 7,210,176 (Weedling).
- Patients particularly those that are morbidly obese, often have coexisting physical conditions, including chronic lesions or wounds on portions of the hips, buttocks, legs, and feet on which the patient's weight is normally supported. Treating these wounds, including activities such as changing wound dressings, typically requires lifting the hips, buttocks, legs or feet of a patient, and sometimes necessitates rolling a patient on his or her side. For morbidly obese patients, these actions can be particularly problematic. First, the sheer weight of the patient's hip, buttock, or leg (perhaps in excess of 200 pounds) may be difficult for a caregiver to manipulate and support. Second, rolling a patient can cause damage to the area under treatment, as well as to adjacent areas of the skin and underlying tissue.
- a patient support device having a mattress including an inflatable plenum.
- An inflatable torso support chamber is located on one end portion of the mattress to elevate the upper torso of a patient with respect to the lower torso and legs, the torso support chamber being isolated from the plenum so as to be separately inflatable.
- An inflatable lower extremity support chamber is located on an opposite end portion of the mattress to elevate one or more lower extremities of a patient with respect to the upper torso and lower torso, the lower extremity support chamber being isolated from the plenum and the torso support chamber so as to be separately inflatable.

Description
- This application claims priority of U.S. Provisional Application No. 61/365,618, filed Jul. 19, 2011, entitled “Patient Positioning Device with Leg Raiser”, which is incorporated herein by reference in its entirety.
- The present invention relates to a patient support device. More particularly, the present invention relates to a patient support mattress with a lower extremity raiser, which may be useful for raising and supporting the buttocks, upper legs, knees, and/or lower legs of obese patients for the purpose of providing medical treatment to the hips, legs, and feet.
- Patient support devices, including patient transfer mattresses, have an inflatable plenum that provides an air cushion to lifts and support a patient laying on a bed or other support surface. Some contemporary examples of patient transfer mattresses are disclosed in U.S. Pat. No. 7,210,176 (Weedling).
- Patients, particularly those that are morbidly obese, often have coexisting physical conditions, including chronic lesions or wounds on portions of the hips, buttocks, legs, and feet on which the patient's weight is normally supported. Treating these wounds, including activities such as changing wound dressings, typically requires lifting the hips, buttocks, legs or feet of a patient, and sometimes necessitates rolling a patient on his or her side. For morbidly obese patients, these actions can be particularly problematic. First, the sheer weight of the patient's hip, buttock, or leg (perhaps in excess of 200 pounds) may be difficult for a caregiver to manipulate and support. Second, rolling a patient can cause damage to the area under treatment, as well as to adjacent areas of the skin and underlying tissue.
- In one embodiment, a patient support device is disclosed having a mattress including an inflatable plenum. An inflatable torso support chamber is located on one end portion of the mattress to elevate the upper torso of a patient with respect to the lower torso and legs, the torso support chamber being isolated from the plenum so as to be separately inflatable. An inflatable lower extremity support chamber is located on an opposite end portion of the mattress to elevate one or more lower extremities of a patient with respect to the upper torso and lower torso, the lower extremity support chamber being isolated from the plenum and the torso support chamber so as to be separately inflatable.

FIG. 1 shows aninflatable mattress 10 that includes atop sheet 12, abottom sheet 14 andside panels 16 sealed together to form a plenum. If themattress 10 is used as a transfer mattress, thebottom sheet 14 may include a plurality of openings for discharging air from themattress 10 to create an air cushion beneath the mattress to facilitate sliding of themattress 10 along an underlying support surface. Thetransfer mattress 10 may include loopedhandles 18 andstraps 19 secured to the sides of themattress 10 to facilitate application of a pulling force to guide the movement of mattress, as well aspatient restraint straps 20 for securing a patient to the mattress. - The
inflatable mattress 10 may include longitudinally extendingside air chambers 22 and transverse chambers 24 extending between theside chambers 22. Themattress 10 includes ahead portion 26 at one end, afoot portion 28 at an opposite end, and anintermediate portion 30 located between the head andfoot portions - The
head portion 26 of thetransfer mattress 10 includes an uppertorso support chamber 40 bounded on its top surface by thetop sheet 12 and on its sides byside panels 32. Thetorso support chamber 40 is preferably separately inflatable and deflatable from the main plenum of themattress 10. Theside panels 32 have a triangular shape that results in a sloped elevation of thetop sheet 12 in thehead portion 26 of themattress 10 above the rest of thetop sheet 12 when the uppertorso support chamber 40 is inflated. In the depicted embodiment, theside panels 32 are dimensioned such that thetop sheet 12 is inclined at a substantially uniform rate throughout a majority of thehead portion 26. The angle of inclination, 0, oftop sheet 12 in thehead portion 26 with respect to portion of thetop sheet 12 between theintermediate portion 30 and thefoot portion 28 may be between approximately 30 degrees and approximately 40 degrees when fully inflated and not loaded by a patient. The invention, however, is not limited to any particular angle of inclination. The inclination elevates the head and upper torso of a supported patient above the patient's lower torso and legs. Supporting an obese patient in a more upright position facilitates circulation and respiration, both at rest and lateral transfer. - The
mattress 10 includes anair inlet hose 31 for supplying air to the plenum to inflate themattress 10. Thetorso support chamber 40 may communicate with the plenum of themattress 10 so that thetorso support chamber 40 and the plenum of themattress 10 can be inflated and deflated together. Constructed in this manner, theentire mattress 10, including theinclined head portion 26 defined by thetorso support chamber 40, would be inflated in common from the same source of air via theair inlet hose 31. Alternatively, thetorso support chamber 40 may be is isolated from the remainder of themattress 10. Arranged in this manner, thetorso support chamber 40 could receive a separate supply of air through an inlet valve orair inlet hose 41 for optional inflation of thetorso support chamber 40 when desired. Such an arrangement provides the option of supporting a patient in a substantially flat position, or in a more upright position. -
FIG. 1 shows a first embodiment of a lowerextremity support chamber 90 located on thetop sheet 12 in thefoot portion 28 of themattress 10. The lowerextremity support chamber 90 may be positioned to support various portions of a patient's leg or legs (lower extremities). As depicted, the lowerextremity support chamber 90 is positioned to raise the lower legs or calves of a patient to cause the legs and feet to extend outward above thetop sheet 12, in order to facilitate treatment of the feet and lower calves. For example, a caregiver can inflate the lowerextremity support chamber 90 to raise the feet of a patient to change a negative pressure wound dressing on the heel or ankle. The lowerextremity support chamber 90 may communicate with the plenum of themattress 10 so that the lowerextremity support chamber 90 and the plenum of themattress 10 can be inflated and deflated together. However, the lowerextremity support chamber 90 is preferably separately inflatable and deflatable via valves to a common air source (not shown) or via anair inlet hose 91 from a separate air source. The lowerextremity support chamber 90 may be used alone or in combination with thetorso support chamber 40 to position the patient as desired. When each of themattress 10, thetorso support chamber 40, and the lowerextremity support chamber 90 is separately inflatable and deflatable, each can be selectively inflate or deflated separately from the others. - Also shown in
FIG. 1 is hipregion support chamber 80 that is centrally located on themattress 10. The hipregion support chamber 80 may positioned beneath the center of a patient's pelvis (i.e., the sacrum), and may be inflated to raise the hips up off thetop sheet 12 of themattress 10. This would enable treatment of regions of the hips, buttocks, and upper thighs that would otherwise be inaccessible, or otherwise would require rolling a patient to one side of the other.
