An intelligent negative pressure wound therapy system includes a foam-type wound dressing, a negative-pressure controller for specifying a supply pressure value and controlling an output pressure supplied to the foam-type wound dressing to create negative-pressure environment; and a pressure sensor electrically coupled to the negative-pressure controller for detecting pressure changes within the negative-pressure environment. If the pressure within the negative-pressure environment exceeds the supply pressure value, the pressure sensor sends a signal to the negative-pres sure controller for adjustment of the output pressure supplied. Thereby the pressure within the negative environment maintains at a value under the supply pressure value. The negative pressure wound therapy system of the disclosure monitors the pressure changes at all times and adjusts the pressure to a value under the supply pressure value, such that the foam-type wound dressing forms a substantially tight seal over a wound.本發明係關於一種智慧型控制負壓傷口系統,係設有一負壓泡棉敷料;一負壓控制器,係可供設定一輸送壓力值,以控制輸出一壓力至該負壓泡棉敷料,使該負壓泡棉敷料產生一負壓環境;一壓力感測器,其係訊號連接至該負壓控制器,以隨時感應該負壓環境內的該壓力變化,於該壓力超出該輸送壓力值時,該壓力感測器會控制該負壓控制器調整所輸出之該壓力,使該負壓環境維持在該輸送壓力值之範圍內。藉以能隨時監測該壓力變化,並調整該壓力使其可維持於所設定的該輸送壓力值之範圍內,以及使該負壓泡棉敷料可以在傷口內完全密合。
