Abstract: Embodiments of a reduced pressure system and methods for operating the system are disclosed. In some embodiments, the system can include one or more processors responsible for various functions associated with various levels of responsiveness, such as interfacing with a user, controlling a vacuum pump, providing network connectivity, etc. The system can present GUI screens for controlling and monitoring its operation. The system can be configured to determine and monitor flow of fluid in the system by utilizing one or more of the following: monitoring the speed of a pump motor, monitoring flow of fluid in a portion of a fluid flow path by using a calibrated fluid flow restrictor, and monitoring one or more characteristics of the pressure pulses. The system can be configured to provide external connectivity for accomplishing various activities, such as location tracking of the system, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

Abstract: Embodiments of a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.
