近年來隨著人口高齡化，高齡人口的增加為醫療單位帶來更大的負擔，因此如何透過醫療輔助科技來降低住院意外的發生將成為醫院關注的重要議題，眾多住院意外當中又以跌倒對高齡者所造成的威脅最大，不但有立即性的危險，留下的後遺症更會加重照護者與健保的負擔。為降低跌倒所造成的二度傷害，醫院或療養院多採用離床警報器於病人下床時主動通知護理師或看護進行協助，然而目前市面上的相關產品之偽警接過於頻繁，接觸式的設計也容易導致長期臥床的病人長褥瘡，不只讓照護者疲於奔命，在分秒必爭的醫院中更可能耽誤關鍵的救援時機。
基於上述議題，本研究與成功大學電機工程學系團隊合作開發具非接觸式與低誤報率兩種特點之新型離床警報系統。根據護理師臨床之照護經驗，於病人下床最常經過的路線上設置紅外線、超音波與三軸加速度計等多重感測器，以監測病人有無離床之舉動，偵測結果會即時顯示於護理站電腦介面以及護理人員手中的APP。當病人離床時，除了護理站會接到警報提醒護理師盡快前往支援外，病床端亦會發出警報，以語音提示病人留在原地等候協助。本論文針對此新型離床警報系統之外殼結構與系統介面進行設計與實作，並反覆迭代修正。

In recent years, with the aging of the population, the increase of the elderly population has brought a greater burden to medical units. Therefore, how to reduce the incidence of hospitalization accidents through medical assistive technology will become an important issue of concern to hospitals. Elderly people pose the greatest threat. Not only are there immediate dangers, but the sequelae left behind will increase the burden of caregivers and health care. In order to reduce the second-degree injury caused by falls, hospitals or nursing homes often use bed-out alarms to actively notify the nurse or nursing staff to assist when the patient gets out of bed. However, the false alarms of related products on the market are too frequent and the contact design is It is also easy to cause bedsores in patients who have been bedridden for a long time, which not only makes caregivers exhausted, but also delays critical rescue opportunities in hospitals where every second counts.
Based on the above issues, our team and the Electrical Engineering Department of Cheng Kung University have developed a new out-of-bed alarm system with both non-contact and low false alarm rates. According to the clinical nursing experience of nurses, multiple sensors such as infrared, ultrasonic and three-axis accelerometer are installed on the most frequent route of getting out of bed to monitor whether the patient is getting out of bed. The detection result will be displayed in nursing care immediately. Station computer interface and APP in the hands of nursing staff. When the patient leaves the bed, in addition to receiving an alarm at the nursing station to remind the nurses to come to support as soon as possible, an alarm will also be issued at the bedside to remind the patient to stay where they are waiting for assistance. This thesis designs and implements the shell structure and system interface of this new type of bed exit alarm system, and iteratively revises it.
