摘要

腦中風病患可能因自律神經系統傳導障礙及腦部灌流異常併發姿勢性低血壓、暈眩、盜汗、視力模糊、失去意識等症狀。腦中風患者術後身體狀況穩定後，需透過復健工作以恢復正常生活能力，其中又以傾斜床復健訓練，因在療程中需要人工控制傾斜床，及量測病人之生命資訊，花費人力最多，時間最長。本研究以整合式智能型量測設備設計為著眼，針對患者在傾斜床復健時，設計一套自動控制傾斜床啟動及量測腦中風病患之血壓、血氧、脈搏等生理資訊參數，並藉由無線網路傳輸系統即時將所量測之病患生理資訊及治療狀況傳送至雲端系統；並將脈搏訊號量化為心率變異，探討腦中風病患於傾斜床治療測試期間發生姿勢性低血壓併發暈眩症狀與心率變異及血壓之關係。了解病患暈眩症狀即時相關生理資訊，以預防病患因併發症造成更大之傷害，同時可提升醫療品質與降低醫護人員之負擔與設備成本。進而可藉由攜行輕便、有(無)線網路傳輸及資料庫儲存整合包裝成可攜式之醫護包，提供醫院復健或社區腦中風病患做更多之醫療照護服務。

Because of the autonomic nervous system conduction disorders and brain perfusion abnormalities, a stroke patient may be complicated by symptoms such as orthostatic hypotension, dizziness, sweating, blurred vision, and the loss of consciousness. When a stroke patient's health condition stabilizes after an operation, a patient must take the rehabilitation to restore the ability to live a normal life. Among all the rehabilitations, the tilt table rehabilitation training, because it requires a manual control and measures a patient's physiological information, it consumes the most manpower and spends the longest hours. In this study, we design an integrated intelligent biosensor system for patients using the tilt table during the rehabilitation, automatically switching on and measuring a stroke patient's physiological parameters, such as blood pressure, blood oxygen, and pulse. Then the gathered physiological information and treatment status are sent to a cloud system by WI-FI. Moreover, a patient’s pulse is quantified as the heart rate variability in order to study the relationship between heart rate variability and blood pressure, which are complicated by orthostatic hypotension during the tilt table training. To understand the immediate relevant physiological information like dizziness , it could avoid the complications that may cause more harms on patients. Meanwhile, it could enhance the medical quality and lower the loading and equipment cost of health care. Thus, with portable device, WI-FI connection, and database storage, the health care package is provided to stroke patients during the rehabilitation in the hospital or in the community for more medical care service.
