A negative pressure wound dressing is provided. The negative pressure wound dressing sequentially includes a backing layer, an indicating layer, a liquid impermeable, gas permeable layer, an absorbing layer and a wound contacting layer, wherein, the backing layer comprises a connecting hole for fluidly connecting a negative pressure source, and at least one visual indicator is disposed on the surface toward the backing layer of the indicating layer. The user can be reminded to change the dressing timely by the visual indictor which can detect the wound exudates absorption of the absorbing layer to effectively improve the healing of the wound by using the negative pressure wound dressing of the present invention.一種負壓傷口敷料,其結構依序包含有一背材、一指示層、一阻水透氣層、一吸收層以及一傷口接觸層。其中,背材具有一連接孔,用以流體地連接一負壓源,且指示層朝向背材之一表面上設有至少一目視指標。利用本創作之傷口敷料可藉由指示層之目視指標感測吸收層所吸收之傷口滲出液之吸收量,提醒使用者適時更換敷料以有效促進傷口癒合。
