Publication number: 20140201919Abstract: A compressible or retractable support is installed inside an air blower cavity of a body support system, such as a medical mattress with forced air flow. The support is compressed or retracted within the cavity when the air blower is inserted in the dynamic configuration of the body support system. The support rebounds to an uncompressed state to fill a greater portion of the air blower cavity when the air blower is removed to convert the body support system to a static configuration.Type: ApplicationFiled: January 18, 2013Publication date: July 24, 2014Inventors: Marc J. Albero, Christopher S. Weyl

Patent number: 8776798Abstract: Method and devices for the prevention and treatment of pressure ulcers are described in which a portable support assembly may be worn by a bed-stricken individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include one or more individual fluid filled pods which are enclosed entirely within an inner fluid pad localized along a central portion. Both the one or more pods and inner fluid pad are then enclosed entirely by another layer of fluid within an outer fluid pad which extends over the entire assembly. Each of the fluid layers may be secured to an outer shell which is relatively stiffer than the fluid layers and may restrict or limit the expansion or movement of the fluid pods and/or fluid pads.Type: GrantFiled: July 22, 2011Date of Patent: July 15, 2014Assignee: PRS Medical Technologies, Inc.Inventors: George Y. Choi, Nikhil Bhat

Patent number: 8769747Abstract: A method for adjusting pressure within an air bed comprises providing an air bed that includes an air chamber and a pump having a pump housing, selecting a desired pressure setpoint for the air chamber, calculating a pressure target, adjusting pressure within the air chamber until a pressure within the pump housing is substantially equal to the pressure target, determining an actual chamber pressure within the air chamber, and comparing the actual chamber pressure to the desired pressure setpoint to determine an adjustment factor error. The pressure target may be calculated based upon the desired pressure setpoint and a pressure adjustment factor. Furthermore, the pressure adjustment factor may be modified based upon the adjustment factor error determined by comparing the actual chamber pressure to the desired pressure setpoint.Type: GrantFiled: April 4, 2008Date of Patent: July 8, 2014Assignee: Select Comfort CorporationInventors: Paul James Mahoney, Mathew Glen Hilden, Matthew Wayne Tilstra

Publication number: 20140173825Abstract: A medical air mattress has a mattress body, a lower bedspread and an upper bedspread. The mattress body is formed by multiple air cells substantially parallel arranged in a row forming an air cell row. The upper bedspread covers the mattress body and is securely connected to the lower bedspread. The mattress further comprises a pumping assembly with a pump and at least a pipeline connecting the pump with the air cells such that inflating and/or deflating of the air cells is controllable selectively.Type: ApplicationFiled: June 18, 2012Publication date: June 26, 2014Applicant: PICARD HEALTHCARE TECHNOLOGY (DONGGUAN) CO. LTD.Inventors: Kuang-Neng Chiang, Hsui-Lun Liang

Patent number: 8756732Abstract: A method for operating an occupant support, at least part of which is orientation adjustable relative to other parts of the occupant support, is disclosed. The method comprises providing, in response to a change of orientation of the orientation adjustable part, a relatively lower occupant/support interface pressure (OSIP) at a location A and a relatively higher OSIP at a location B followed by providing a relatively higher OSIP at the location A and a relatively lower OSIP at the location B.Type: GrantFiled: January 2, 2013Date of Patent: June 24, 2014Assignee: Hill-Rom Services, Inc.Inventor: Charles A Lachenbruch

Patent number: 8756737Abstract: An air tool with a modularized air pad includes several air pad units, each of which has one pad body whose top surface is formed with an accommodating recess and whose one side has an air opening; two air bags disposed at the bottom of the accommodating recess, each of the air bags having two air chambers and connecting to the air opening via an air pipe; and one buffer pad accommodated in the accommodating recess on the air bags. When the air opening is selected to inflate the air chamber of one air bag, the buffer pad undergoes an upward swing motion according to the inflated air bags.Type: GrantFiled: October 13, 2011Date of Patent: June 24, 2014Assignees: Trinity Biotech Co., Ltd.Inventor: Jui-Peng Chan

Patent number: 8757165Abstract: Described herein are systems and apparatuses for enhanced comfort through contact pressure reduction. In particular, the systems and apparatuses disclosed herein prevent or otherwise mitigate pressure by actively orienting a patient over an anatomy-specific pressure-mitigating contact surface on which the patient rests. A pressure-mitigating contact portion of the contact surface includes a plurality of independently pressurized chambers configured in a specific geometric pattern that is designed to mitigate contact pressure between a support surface (e.g., bed or chair) and a specific anatomic region of a patient's body when the specific anatomic region of the patient's body is oriented over an epicenter of the geometric pattern. Additionally, a plurality of elevated side support portions and a wedge interconnected on the base material are configured to actively orient the specific anatomic region of the patient's body over the epicenter of the geometric pattern.Type: GrantFiled: October 25, 2013Date of Patent: June 24, 2014Assignee: TurnCare, Inc.Inventor: Rafael P. Squitieri

Patent number: 8745797Abstract: The objective of the present invention is to provide a mattress including a plurality of cells provided on a body pressure working surface of a substrate that supports a human body, and a pressure control means that changes a setting of a height of each cell by adjusting a pressure in a fluid chamber formed within the cell. An elastic cushion layer is provided on a body pressure working surface of the cells, and a constricted portion is formed in a middle in the height of the each cell so that the body pressure working surface of the cell is allowed to tilt following deformation of the cushion layer as a result of the cells' precession-deformation at the constricted portion.Type: GrantFiled: June 5, 2013Date of Patent: June 10, 2014Assignees: Tokai Rubber Industries, Ltd., Kyushu University, National University CorporationInventors: Akitsugu Misaki, Shin-ichiro Takasugi, Shuji Fukugawa, Mika Wada, Kiyoe Harada, Keiko Miyazaki, Yukiko Tachibana, Yukihide Iwamoto
