  • Patent number: 9554956
    Abstract: The invention comprises of a device that allows health care providers to position the body of a patient for progression of labor, for assistance in fetal resuscitation, and for other medical procedures. The device has inflatable chambers that assist the labor and delivery health care provider in turning a patient onto her right or left side while laying in bed. An inflatable positioning pad is used to further assist with the turning of a patient and/or with the shifting of a patient toward the head or the foot of the bed as needed. This device and method will allow turning to be done frequently, rapidly and safely, especially in pregnant patients with epidurals, that are overweight, or that otherwise have difficulty moving on their own.

  • Patent number: 9066601
    Abstract: The heating and cooling mattress is a mattress for a bed that includes a heating member and a cooling member, which work to either heat or cool the mattress when in use. The heating member is constructed of a heating element that traverses along a first plane, and which evenly distributes heat along an entire surface area of the mattress. The cooling member is constructed of a refrigeration cycle from which a condensing line traverses along a second plane in order to cool down the mattress. The heating member and the cooling member are independent of one another, but work alternately such that either the cooling member or the heating member is only able to operate at a given time. The first plane for the heating member is located at a lower elevation with respect to the second plane for the cooling member.

  • Patent number: 8640281
    Abstract: A non-inflatable resting device used for heating and cooling is provided with a plurality of interconnected channels located close to an external surface of the resting device. Each channel substantially occupies the space between two support beams and the interior of said external surface. The comfort level of the resting devices is considerably increased while maintaining adequate structural integrity of the channels when the support beams are constructed with a cushion material having layers of different hardness levels. The top layer is a cushion material with high initial softness ratio. The arrangement of the channels and beams allows a non-pressurized conditioned fluid to flow underneath of the external surface providing a resting device with a heating and cooling system with unmatched energy efficiency. The high energy efficiency of the proposed resting device is due to the elimination of the compressor motor and the thick cushion layer used on the top surface as required by the competition.

  • Publication number: 20140026320
    Abstract: A climate controlled seat, bed or other assembly configured to receive a person includes a blower and two or more thermoelectric devices or other conditioning fluid modules. According to one embodiment of an operational scheme, a control system for the seat or bed is configured to continuously discharge air from the blower through the thermoelectric devices. In one arrangement, the thermoelectric devices are sequenced between an activated and a deactivated position. Consequently, the desired cooling and/or cooling effect can be maintained while reducing energy consumption of the climate control system.

  • Patent number: 8555440
    Abstract: An air mattress has a top chamber and a bottom chamber separated by a barrier. The patient rests on the top surface of the top chamber, which has a plurality of apertures discharging air through apertures that are not blocked by the patient. The top chamber is provided with temperature-controlled heated or cooled air at a regulated pressure. Heated or cooled air from the top chamber is delivered to an area substantially surrounding the patient. The bottom chamber has a bottom surface containing a plurality of apertures that remain closed due to the weight of the mattress and the patient when the pressure-regulated air is beneath a pre-selected value. When the air pressure is increased, the apertures at the bottom surface of the bottom chamber emit air, creating an air cushion underneath the air mattress that facilitates lateral movement of the mattress over a flat or irregular surface, such as from a hospital bed to a stretcher, or from a stretcher to an operating table.
