    • The wound dressing combines an integrated mechanical aspirator for drawing exudate and fluids from the wound site and an internal absorbent pad for collecting exudate and fluids within the wound dressing. The collection pad has multi-layers including a layer of hyper-absorbent material, which acts as the fluid collection medium. The aspirator is a type of simple bulb syringe, which is integrated into top of the wound dressing in fluid communication with the collection pad. The aspirator has a hollow bulb head and a one-way purge vent. The vent allows air to be purged from the bulb head when manually compressed. Once compressed, the structural and material resilience of the bulb head causes its walls to expand back to their original shape thereby creating a vacuum (negative) pressure within the bulb head that assists in drawing exudate and fluids from the wound site into the collection pad.
    • 创伤敷料结合了一个集成的机械抽吸器,用于从伤口部位吸出渗出物和液体,并且内部吸收垫用于收集伤口敷料中的渗出物和流体。 收集垫具有多层,包括作为流体收集介质的超吸收材料层。 抽吸器是一种简单的灯泡注射器,其集成到与收集垫流体连通的伤口敷料的顶部。 吸气器具有中空灯泡头和单向吹扫口。 当手动压缩时,通风口允许空气从灯泡头被清除。 一旦被压缩,灯泡头的结构和材料弹性使其壁膨胀回到其原始形状,从而在灯泡头内产生真空(负)压力,其有助于将渗出物和流体从伤口部位吸入收集垫中。
