A novel instrument has been developed to determine the fluid handling capacity of different types of wound dressings, irrespective of their structure and composition. The instrument is developed with custom built wound bed/plate with specially designed path to control the amount and flow rate of wound exudates, simulating the actual wound alike conditions. The instrument has provision to apply compression / pressure over wound dressing while testing to similar realtime compression / pressure applied on wound dressing. The study was carried out using different types of commercially available wound dressings. It is found that the developed instrument is able to test different types of dressings effectively for fluid handling capacity. The results obtained by new instrument are found comparable with the existing methods. The existing methods give only single value of fluid handling capacity at the defined hour as compared to the new instrument which gives online continuous results from zero to 48 h. This real time data may be useful for defining the effectiveness of dressings at a particular time interval. The data obtained from the instrument can also be used to know the saturation point and change with time for a particular dressing. The repeatability of results are also proven. Also the instrument is able to test fluid handling capacity of dressings with and without pressure.

设计和制造用于评估伤口护理敷料的液体处理能力特征的仪器

已经开发出一种新颖的仪器来确定不同类型的伤口敷料的流体处理能力，而不论其结构和组成如何。该仪器使用定制的伤口床​​/平板开发，具有专门设计的路径，可控制伤口渗出液的数量和流速，模拟实际伤口情况。该仪器可以对伤口敷料施加压缩/压力，同时可以测试对伤口敷料施加的类似实时压缩/压力。该研究使用不同类型的市售伤口敷料进行。发现该开发的仪器能够有效地测试不同类型的敷料的流体处理能力。发现通过新仪器获得的结果与现有方法相当。与新仪器相比，现有方法只能在定义的小时内提供单一值的流体处理能力，而新仪器可以提供从零到48小时的在线连续结果。该实时数据对于定义特定时间间隔的敷料的有效性可能有用。从仪器获得的数据还可用于了解饱和点并针对特定敷料随时间变化。结果的可重复性也得到了证明。该仪器还能够测试在有压力和无压力的情况下敷料的流体处理能力。从仪器获得的数据还可用于了解饱和点并针对特定敷料随时间变化。结果的可重复性也得到了证明。该仪器还能够测试在有压力和无压力的情况下敷料的流体处理能力。从仪器获得的数据还可用于了解饱和点并针对特定敷料随时间变化。结果的可重复性也得到了证明。该仪器还能够测试在有压力和无压力的情况下敷料的流体处理能力。
