    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 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 system can be configured to efficiently deliver negative pressure in continuous and intermittent modes. The system can also be configured to gradually ramp up and down to set pressure values. The system can also be configured to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Detection and indication of the presence of at least some of these conditions can be enabled and disabled.

    摘要： Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

    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.
