    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.

    摘要： Leak location devices and methods of using leak location devices that can be used in conjunction with negative pressure wound therapy systems are disclosed. In some embodiments, a leak location device can include a microphone for detecting sound pressure produced by a leak. Detected sound pressure can be compared to a threshold, which can correspond to background or ambient sound pressure. Background or ambient sound pressure can correspond to sound produced by a negative pressure source. The leak detection device can include a display configured to visually depict the detected sound, and a light source which creates a visual depiction of the coverage angle of the microphone.

    摘要翻译： 泄漏定位装置和使用可与负压伤口治疗系统结合使用的泄漏定位装置的方法被公开。 在一些实施例中，泄漏定位装置可以包括用于检测由泄漏产生的声压的麦克风。 检测到的声压可以与阈值进行比较，这可以对应于背景或环境声压。 背景或环境声压可以对应于由负压源产生的声音。 泄漏检测装置可以包括被配置为可视地描绘检测到的声音的显示器和产生麦克风的覆盖角度的视觉描绘的光源。
