近年來受國內人口高齡化與慢性疾病年輕化的影響，導致慢性傷口之照護需求大幅提升，如糖尿病足潰瘍、壓力潰瘍及靜脈性潰瘍等，由於上述症狀通常需要長時間護理治療，造成醫療人員勞力與患者家屬經濟負擔。為改善慢性傷口的復原速度，此負壓傷口治療技術被廣泛用於醫療院所。而目前醫院使用的負壓傷口治療系統體積大而易造成患者行動不便，市售之穿戴式負壓產品雖方便隨身攜帶使用，卻缺乏遠端傷口監控功能而無法隨時掌握病患傷口的復原情況。
針對上述議題，本論文提出一具傷口監控之穿戴式負壓傷口治療系統，能收集患者傷口周圍環境之壓力、溫度與濕度數據並整合開源雲端平台使醫護人員可從遠端監測傷口狀態。所偵測之傷口周圍溫濕度值以模糊控制方式對負壓進行調控，以提供穩定且適當的負壓環境進行傷口治療。而為避免傷口環境過濕造成潰爛及過乾抑制細胞生長，本系統感測濕度值大小，協助醫護人員判斷更換敷料的時機。此外本系統使用顏色感測器測量不同pH值之螢光染劑於PVDF膜和敷料上的顏色變化以模擬傷口pH值，判斷傷口是否受感染。從實驗結果得知藍色光於pH7至7.3之間變化幅度於PVDF膜及敷料上分別可達11.5%及19.6%，藉此可讓醫護人員在不移除敷料的情況下，評估傷口的復原狀況。而MATLAB模擬及導入系統後之壓力輸出比較結果，其平均誤差僅0.2278kPa。透過本系統將降低醫護人員負擔、減少患者住院成本，並讓患者擁有較佳的自主行動能力，達到提升病患生活品質及住家醫療照護目標。

This work presents the wearable Negative Pressure Wound Therapy (NPWT) system with wound monitoring, which can collect the values of pressure, temperature, humidity and color variation around the patients’ wound and integrate the open source cloud platform to provide caregivers to monitor wound status from remote location. The values of temperature and humidity detected from wounds are used to adjust negative pressure values by Fuzzy control. Therefore, the system can provide stable and appropriate negative environment to treat the wounds. The system also detects the humidity value to assist the caregivers to determine the occasion of changing dressings, avoiding wound ulceration at the over wet environment and suppressing the growth of cells at the over dry environment. Furthermore, the color variation of fluorescent dyes on PVDF membranes and dressings is measured by color sensors to simulate wound pH values, assessing whether the wound is infected. The results demonstrate the accuracy and stability of above functions on proposed system.
