基於IEEE 11073 PoCD標準之定點照護設備通訊控制系統

A Point-of-Care Device Communication Controller System Based on IEEE 11073 PoCD Standards

隨者資通訊科技的快速成長及醫院照護人力與方式的轉變，醫院端的醫療器材具備通訊功能已經成為重要的趨勢。目前有一些研究及產品著眼於個人照護等級之醫療器材，其採用國際醫療器材通訊標準協定，但此些研究並未涵蓋醫院端之需求。個人健康照護設備與醫院端之設備存在許多的差異，包括使用情境，受測者狀況，受測環境，通訊方式，甚至量測資訊之即時性需求等。再者，就醫院端的生理量測設備而言，需要考慮減少護理師的工作量或是避免以手抄寫的錯誤發生，以及生理量測資訊之分析與統計有助於醫護人員對病患之後續照護等。本研究所提之定點照護設備通訊控制系統是基於IEEE 11073 Point-of-CareDevice（PoCD）通訊標準所設計。定點照護設備通訊控制系統透過乙太網路連接Philips IntelliVue系列之生理監測設備，當生理監測設備感測病患之生理量測資訊後，將此些資訊轉換成符合IEEE 11073 PoCD為主之資訊格式。透過乙太網路傳輸介面，將此些標準化之生理量測資訊傳送到定點照護設備通訊控制系統。實驗結果顯示，生理量測資訊能成功地透過Ethernet介面，傳送到定點照護設備通訊控制系統。 With the rapid growth of Information and Communication Technology(ICT) and the transition of hospital care manpower and manner, bedside medical device with communication ability becomes important functionality. Current researches focus on personal health-care medical devices that adopt internal medical device communication standards. But, these researches do not discuss the hospital requirements. There are many differences between the personal health-care device and the point-of-care device. For example, use cases, patient conditions, environment, communication interface, and real-time data upload requirement. In addition, for point-of-care patient monitor in hospital, we need to concern how to reduce staff loading and human error, and the benefi t of the analysis and statistics of vital sign data for healthcare providers. The design for the PoCD communications controller system proposed in this paper is based on the ISO/IEEE 11073 Point-of-Care Device(PoCD) communication standards. The PoCD communications controller system connects to the Philips IntelliVue series patient monitor through Ethernet. When the Philips IntelliVue patient monitor senses the physical activities from the users, and then transmits these data to the PoCD communications controller system in compliance with IEEE 11073 PoCD data format and protocol standards via the Ethernet interface. Based on the testing results, users can transmit measurement data to the PoCD communications controller system over the Ethernet interface successfully.
