  • Patent number: 11253411
    Abstract: A patient immersion sensor includes a radio detection and ranging (RADAR) apparatus to determine a time of flight (TOF) of a RADAR pulse and a reflected signal that is reflected by a patient or by a portion of a patient support surface supporting the patient. The TOF is indicative of an immersion depth or a distance toward bottoming out of a patient supported on the patient support surface, such as a mattress or a pad. The RADAR apparatus emits pulses of very short duration so as to be able to detect objects, such as a patient or a portion of a mattress or pad, at very close distances. The RADAR apparatus may use time-of-flight (TOF) between transmission of the pulse and receipt of a reflected signal to determine a distance toward bottoming out by the patient, thereby to determine if the patient is properly immersed into the patient support surface.

  • Patent number: 10368796
    Abstract: Systems and methods for monitoring pressure exerted on an individual at one or more points by a support structure and adjusting the support structure in response to the monitored pressure are disclosed. The method for monitoring pressure may include the step of periodically receiving with at least three radio frequency readers, localized contact pressure data from a radio frequency addressable sensor placed on an individual. The method may further include, when an adjustment is required, calculating a radial distance defining a radius of the radio frequency addressable sensor to the at least three radio frequency readers, and calculating an intersection location or overlap of the radii such that the location of the radio frequency addressable sensor is determined. The method may also include, when the location of the radio frequency addressable sensor is determined, adjusting cells within a zone or subzone corresponding to the location.

  • Patent number: 10352804
    Abstract: A method of individually pressurizing a plurality of air tubes includes the steps of providing a sealed tube body, a pressure sensor, an inlet/outlet valve for each of the plurality of air tubes, a control unit, and an air circulation system. The steps also involve retrieving an initial pressure setting for each of the plurality of air tubes with the control unit; measuring a current pressure within the sealed body; comparing the initial pressure setting to the current pressure for each of the plurality of air tubes; opening the inlet/outlet valve of an off-pressure tube and pumping air into the sealed tube body of the off-pressure tube with the air circulation system, if the current pressure is lower than the initial pressure setting; and opening the inlet/outlet valve of the off-pressure tube and releasing air out of the sealed tube body of the off-pressure tube with the air circulation system, if the current pressure is higher that the initial pressure setting.

  • Patent number: 10335335
    Abstract: For each air cell, air is supplied and discharged through one of three lines independent of one another, every third cell being connected to the common line. The control unit controls inflation and deflation of air cells in turn in such an alternate manner that first the pressure of air in the air cells on the first line is increased and decreased, secondly the pressure of air in the air cells on the second line is increased and decreased, then the pressure of air in the air cells on the third line is increased and decreased. Thereafter, when the back tilt angle of the back bottom has reached a predetermined angle or greater, the control unit increases the pressure of air cells whose pressure is being lowered at that moment so as to produce an inflated mode similar to that of the other air cells. Then, while the back bottom is being raised, the control unit performs an inflation and deflation control of individual lines alternately on a cycle shorter than that in a normal control mode.

  • Patent number: 10143609
    Abstract: A medical air mattress has a mattress body and an upper bedspread. The mattress body is formed by multiple air cells including independent air cells parallelly arranged as an air cell row. The upper bedspread covers the mattress body. The independent air cells are connected to the independent deflating unit to be deflated independently. When the patient needs to use the bedpan, the independent air cells are deflated to form a recess for receiving the bedpan so that the patient needs not to move.

  • Patent number: 10045632
    Abstract: A traveling wave air mattress apparatus includes an air mattress comprised of an array of laterally disposed, longitudinally spaced air bladder cells that are individually inflatable to quiescent pressure levels which provide comfortable support for a human body, and an air pressure-pulse generator controlled by a wave sequence generator for periodically introducing into sequences of the air bladder cells timed sequences of air pressure pulses which vary pressures in the cells from quiescent pressures, the air pressure variations resulting in leading and lagging soliton-like traveling waves of body support force variation which travel longitudinally over the surfaces of the pulsed air bladder cells, thus inhibiting formation of bedsores. The wave patterns may optionally simulate water waves and/or rocking motions of a boat to produce relaxing effects.
