Patent number: 9901664Abstract: Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor a duty cycle of a source of negative pressure. Based on the monitored duty cycle, the controller can determine whether a leak is present and provide an indication to a user. The controller can determine a duty cycle threshold in order to achieve an optimal or near optimal balance between an uninterrupted delivery of therapy, avoidance inconveniencing a user, conserving power, achieving optimal or near optimal efficiency, and/or limiting vibrational noise. In some embodiments, the duty cycle threshold is determined based at least in part on a capacity of a power source and an operational time of the apparatus.Type: GrantFiled: March 13, 2013Date of Patent: February 27, 2018Assignee: SMITH & NEPHEW PLCInventor: Ben Alan Askem

Publication number: 20170368239Abstract: Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes applying a drive signal to a pump assembly of the pump system, the drive signal alternating between a positive amplitude and a negative amplitude and the drive signal having an offset, and sampling a pressure within a fluid flow path configured to connect the pump system to a wound dressing configured to be placed over a wound during one or more time intervals. Each of the one or more time intervals can occur when the drive signal is approximately at an amplitude equal to one or more sampling amplitudes.Type: ApplicationFiled: December 21, 2015Publication date: December 28, 2017Inventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva

Publication number: 20170304510Abstract: Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.Type: ApplicationFiled: July 12, 2017Publication date: October 26, 2017Inventors: Ben Alan Askem, Sarah Jenny Collinson, John Cowan-Hughes, Christopher John Fryer, Tom Moy, Paul Mullen, Derek Nicolini, Neil Pryor, Philip Walsh, Ian Binder
