實現UHF RFID系統以追蹤需消毒呼吸治療設備

摘要醫療物資管理系統能提高管理效率與物資追蹤，計算正確的庫存量，降低庫儲成本及避免存貨放置過久，此外精確計算庫存亦可達到減少補貨次數的效果。當沒有自動化的管理，這些大量的醫療產品與物資，都需要花費大量的人力與時間管理。本研究以無線射頻辨識(Radio Frequency IDentification，縮寫RFID）技術為基礎，將原用途使用在洗衣的超高頻電子標籤，與醫療器材結合後，開發出一套被動式UHF RFID以追蹤需消毒呼吸治療設備系統，透過固定在醫材上的標籤，用來追溯與監控醫材消耗。系統由UHF RFID電子標籤與UHF RFID讀取器組成，其中包含讀取器的硬體裝置與軟體的寫入資料庫功能；當已裝有超高頻電子標籤的呼吸治療設備靠近讀取器時，讀取器讀取電子標籤的資料後，上傳與儲存於資料庫。根據本研究結果，透過此系統自動及正確地記錄物品使用次數、消毒日期，並盡量降低改變臨床人員工作型態，以達到減少人為操作錯誤。本研究無個別探討損壞原因，而是用臨床人員觀點切入，用這套系統做綜合的資源管理與效益評估；雖然引入此系統並無增加收益，但若各部門以這套系統的統計資訊來訂出管理方針，就能有效的管控成本、增加病人安全、減少醫護人員的工作量與需要承擔的責任。

Abstract The medical supplies management system is able to improve management efficiency and material tracking, calculate the inventory correctly, reduce storage costs, and avoid overstocking. Apart from that, the replenishment could become less frequent due to more accurate inventory. It could cost a lot of time and require large amounts of manpower to manage these large quantities of medical products and materials without automatic management. This study is based on the radio frequency identification (Radio Frequency IDentification, abbreviated RFID) technology. Through combining UHF electronic tags which were used by the laundry industry with medical devices, it has been developed a passive UHF RFID system for tracing the respiratory therapy equipment which requires to be disinfected. The medical equipment is able to be tracked and monitored the consumption of the medical equipment by securing the tags to it. The system is composed of UHF RFID Tag and a UHF RFID reader to read the tag and upload the data. Once the respiratory therapy equipment equipped with the UHF electronic tag is close to the reader, the reader reads the data from the tag, then uploads and saves these in the database. Based on the results of this study, the system could be used to automatically and accurately record the number of consumable used, the date of disinfection, and minimize changes in the working style of clinical staff to reduce human errors. In this study, the system was used for comprehensive resource management and benefit evaluation from the point of view of the clinician. The causes of damage were not discussed in this study respectively. Although the use of the system does not make more profit, any department which uses the statistical information from it to sets the management policies could control costs efficiently, increase patient safety, and reduce workload and responsibility of healthcare staff.
