    摘要： Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure wound therapy apparatus can include a wound dressing, a negative pressure source, and a controller. The negative pressure source can provide negative pressure via a fluid flow path to the wound dressing. The controller can monitor a rate of fluid removal from the wound, wirelessly communicate the rate of fluid removal to a remote device, and output an indication when the rate of fluid removal meets a threshold.

    摘要： Embodiments of negative pressure wound therapy systems and methods are disclosed. In some embodiments, an apparatus includes a housing enclosing a source of negative pressure and a controller configured to operate the source of negative pressure to provide negative pressure wound therapy to a wound. The housing can also include a communications controller configured to wirelessly transmit and receive data using a communications antenna positioned on an antenna board. The antenna board can be mounted to a communications board that include the communications controller. The antenna board can be electrically connected to the communications board via a single connector on the communications board. The antenna's ground plane can be positioned on the communications board.

    摘要： 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 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 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.

    摘要： Embodiments of negative pressure wound therapy apparatuses and methods for using such apparatuses are disclosed. In some embodiments, a negative pressure wound therapy apparatus includes a controller configured to determine a level of exudate in a canister (or a dressing) based at least in part on one or more characteristics of pressure signals generated by a negative pressure source and monitored by a pressure sensor. One such characteristic of the pressure signals can be amplitude, which may increase as a level of exudate in the canister (or dressing) increases. The canister (or dressing) can include a filter configured to become occluded in order to prevent overflow of the canister (or dressing). The controller can be additionally configured to detect and indicate a canister (or dressing) pre-full condition before the filter becomes occluded. More efficient and reliable operation of the negative pressure wound therapy apparatus can thereby be attained.

    摘要： Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly and a wound dressing configured to be positioned over a wound. The pump assembly and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound via a fluid flow path. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of conditions, such as a blockage in a fluid flow path. Monitoring of the conditions can be performed by detecting a level of activity of a pump of the pump assembly.
