Benefits of technology

[0005]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 separ

Problems solved by technology

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.

first embodiment

[0023]FIG. 1 shows a lower extremity support chamber 90 located on the top sheet 12 in the foot portion 28 of the mattress 10. The lower extremity support chamber 90 may be positioned to support various portions of a patient's leg or legs (lower extremities). As depicted, the lower extremity 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 the top sheet 12, in order to facilitate treatment of the feet and lower calves. For example, a caregiver can inflate the lower extremity support chamber 90 to raise the feet of a patient to change a negative pressure wound dressing on the heel or ankle. The lower extremity support chamber 90 may communicate with the plenum of the mattress 10 so that the lower extremity support chamber 90 and the plenum of the mattress 10 can be inflated and deflated together. However, the lower extremity support chamber 90 is preferably separately inflatable and deflatable via valve...

second embodiment

[0026]FIG. 2 shows a lower extremity support chamber 190 located on the top sheet 12 in the foot portion 28 of the mattress 10. As depicted, the lower extremity support chamber 190 has a generally rectangular shape and provides a uniform lift height throughout. The lower extremity support chamber 190 can be used to raise the buttocks and thighs of a patient to provide pressure relief to the lower back, and to enable access to behind the knees and lower legs for treatment. The lower extremity support chamber 190 can be separately inflated via valves (not shown) or the air inlet hose 91.

third embodiment

[0027]FIG. 3 shows a lower extremity support chamber 290, including a right support chamber 290a and a left support chamber 290b. In variations of this embodiment, only one or the other of the support chambers 290a, 290b may be provided. The right support chamber 290a can be used to elevate the right thigh of a patient to provide access to the area behind the knee and along the calf. The left support chamber 290b can perform the same function for the left thigh. The support chambers 290a, 29b may be inflated together via a common air inlet tube 91 (not shown) or may be separately inflatable via valves or separate air supplies indicated generally as air inlet tubes 91a, 91b. Each of the support chambers 290a, 290b has a ramp shape to provide its greatest lift beneath the lower portion of a patient's thigh, and lesser lift going up toward the buttocks. In this way, the knee will be suspended above the top sheet 12 of the mattress 10, and the knee can be used as a fulcrum for a caregiv...

Abstract

A patient support device includes a mattress including an inflatable plenum, an inflatable torso support chamber 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, and an inflatable lower extremity support chamber 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

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]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.FIELD OF THE INVENTION[0002]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.BACKGROUND OF THE INVENTION[0003]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).[0004]Patients...
