Patent number: 10993862Abstract: 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.Type: GrantFiled: August 18, 2015Date of Patent: May 4, 2021Assignee: HUNTLEIGH TECHNOLOGY LIMITEDInventors: Glenn C. Stroh, Randall P. Kelch, Kenneth M. Knowles

Patent number: 10806835Abstract: 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.Type: GrantFiled: February 7, 2018Date of Patent: October 20, 2020Assignee: KCI Licensing, Inc.Inventors: Randall P. Kelch, Xiaolu Zheng, Reuben Walter Edgar, Jr., Jonathan Paul Jaeb, Thomas Paul Lawhorn, Shannon C. Ingram

Patent number: 10470956Abstract: 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.Type: GrantFiled: July 24, 2015Date of Patent: November 12, 2019Assignee: Huntleigh Technology LimitedInventors: Randall P. Kelch, Michelle Krysztopik, Shih-Hsun Tu, Wen-Yen Lee

Patent number: 10258538Abstract: 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.Type: GrantFiled: June 21, 2018Date of Patent: April 16, 2019Assignee: Huntleigh Technology LimitedInventors: Eric Barta, Steven Torno, Lisa M. Paige, Michael Oliva, Rico Jaeger, Randall P. Kelch
