Publication number: 20230398304Abstract: A drug delivery system comprising drug expelling means and electronic circuitry with a sensor system adapted to determine an expelled amount of drug, the sensor system comprising a switch for actuating the sensor system between an off and on state. The electronic circuitry is adapted to actuate the sensor system from a high-power on-state to a low-power sleep state after a given amount of time to save energy, and, with the sensor system in the low-power sleep state, detect when the switch is actuated from the on-state to the off-state, this creating an error period. When an error period has been detected a display indicates to the user that the sensor system has been in an error state for a period of time corresponding at least to the error period.Type: ApplicationFiled: October 29, 2021Publication date: December 14, 2023Inventors: Bennie Peder Smiszek Pedersen, Laurits Hoejgaard Olesen, Lorenzo Bernardini, Paolo Forzani, Kim Ejholm Hansen

Publication number: 20230355861Abstract: 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 causing provision of negative pressure, via a flow path, to a wound dressing configured to be positioned over a wound, the flow path configured to fluidically connect the pump system to the wound dressing, measuring a first pressure value in the flow path at a first time, measuring a second pressure value in the flow path at a second time, calculating a first rate of pressure change using the first and second pressure values, and in response to determining that the calculated first rate of pressure change satisfies a threshold rate of change, providing an indication that the wound dressing is full, wherein the method is performed under control of a controller of the pump system.Type: ApplicationFiled: May 1, 2023Publication date: November 9, 2023Inventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva

Patent number: 10973965Abstract: Systems and methods for controlling and/or calibrating a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes calculating an amplitude and an offset for a drive signal based at least in part on previously calculated parameters and a negative pressure setting, generating the drive signal, and applying the drive signal to a pump system. The pump system can be fludicially connected to a wound dressing positioned over a wound.Type: GrantFiled: December 21, 2015Date of Patent: April 13, 2021Assignee: Smith & Nephew PLCInventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva

Patent number: 10780202Abstract: Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing.Type: GrantFiled: December 21, 2015Date of Patent: September 22, 2020Assignee: Smith & Nephew PLCInventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva

Patent number: 10737002Abstract: 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: GrantFiled: December 21, 2015Date of Patent: August 11, 2020Assignee: Smith & Nephew PLCInventors: Ben Alan Askem, Iacopo Claudio Ferrari, Matteo Foini, Paolo Forzani, Christopher John Fryer, Allan Kenneth Frazer Grugeon Hunt, Christian Riva
