摘要:
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.
