血液透析為臨床常見的治療方法之一，需要在人體手臂表面穿刺並固定針頭，此時發生脫針漏血的風險相當高，一旦洗腎過程中發生漏血，病人在短短幾分鐘內就會有生命危險。本研究利用自行設計的陣列感測貼片搭配映射電路，結合無線傳輸功能，開發可多床使用的穿戴式脫針漏血感測裝置。藉由調整各個感測點的權重比，針對病人漏血量進行不同等級的風險程度判斷。使用上不會壓迫病患廔管及針頭，當發生脫針漏血時，血液導通陣列感測點使電壓準位改變。透過映射電路進行風險程度判定，當漏血達危急的情況，隨即發出聲響與警示燈，同時透過Wi-Fi無線傳送訊息至醫護站，讓護理人員即刻做出適當的處理。此外，根據不同的臨床使用情境，本系統在多床架構下可連續使用約4-6小時，且資料遺漏率小於1%。希望藉由本研究所提出的裝置，改善臨床洗腎機的照護死角，提升臨床洗腎病患的安全，也能作為未來臨床相關應用設備的參考。

Hemodialysis is commonly used in clinical treatment. Long-term hemodialysis treatment generally involves puncturing of the body surface. However, the puncture pinhead placed on the body surface for an extended period of time, may cause higher risk of needle dislodgement and fatal injury to patients. This study developed a wearable device for multi-bed monitoring, with warning function to monitor blood leak of hemodialysis patients, using wireless transmission concurrent with an array sensing patch and mapping circuit. For clinical use, the array sensing patch in this research can be applied to the weights of each sensing point to evaluate different risk levels. Furthermore, for the battery life experiment, the design could be used for up to 4-6 hours of continuous detection during prolonged multi-bed monitoring, and data loss rate is less than 1%. When the patient’s blood has widely spread, the increase in blood leak volume causes the conduction sensors in the array sensing patch to reach a high risk level and immediately activates the alert system composed of sound and light. At the same, Wi-Fi wireless transmission sends data to the data room or nursing station for evaluation and to provide complete health care to all the patients. Through this study, the current medical approach for the treatment of hemodialysis was improved and blind spots encountered by dialysis equipment were reduced. It also acts as reference for device design of future clinically relevant applications.
