  • Patent number: 10993862
    Abstract: A patient support system including a frame having first and second portions, at least one of them movable with respect to the other to transition the frame between a first configuration and a second configuration. A first port is coupled to the first portion of the frame, and a second port disposed with the second portion of the frame, such that a distance between the first port and the second port changes when the frame transitions between the first and second configurations. A fluid conduit is arranged between the first port and the second port and configured to transition between a first length and a second length, longer than the first length, when the frame is transitioned between the first and second configurations. The fluid conduit is configured with a resiliency to naturally return toward the first length. A method of using a patient support system is also included.

  • Patent number: 10806835
    Abstract: A method of treating a tissue site is provided. The method includes applying a reduced pressure to a tissue site with a reduced pressure source. A source pressure is monitored at the reduced pressure source, and a differential pressure is determined between the source pressure and the desired tissue site pressure. If a blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a first maximum differential pressure. If no blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a second maximum differential pressure.

  • Patent number: 10470956
    Abstract: A patient support apparatus includes an inflatable mattress for supporting a patient and an air supply for supplying air to the inflatable mattress. A control system controls the air supply and inflatable mattress to provide therapeutic functions. The control system is configurable to make a subset of the therapeutic functions available to a user. A control panel containing controls for therapeutic functions is provided. An interchangeable bezel covers the control panel to provide access to controls for the subset of available therapeutic functions.

  • Patent number: 10258538
    Abstract: Emergency CPR systems for patient support systems utilizing backup battery power. For example, an emergency CPR switch attached to a hospital bed provided with a patient support platform having a portion that is pivoted between a flat position and an inclined position by a motor powered by a battery during emergency usage. The emergency CPR switch includes: a first relay disposed between the battery and the motor; a controller configured to provide a motor control signal to control the motor; and a switch electrically connected to the first relay. When the switch is operated the first relay is activated to drive the motor with the battery in a direction placing the pivotable portion in the flat position and control of the motor by the motor control signal is disabled or overridden.

  • Patent number: 8439882
    Abstract: A system and method for treating a tissue site of a patient may include sensing one or more characteristics of exudate fluid of a tissue site of a patient. A level of the sensed one or more characteristics of the exudate fluid may be measured, and, in response to the measured at least one characteristic level, treatment may be applied or altered to the tissue site.
