基於MSP430晶片及ISO/IEEE 11073標準之x73-PHD轉換器設計

A Design of x73-PHD Adaptor Based on MSP430 Chipset and ISO/IEEE 11073 Standards

過去，醫療器材與應用伺服主機之間少有互通及資訊分享之機制。但隨者高齡人口的趨勢，Health2.0概念的誕生，醫療器材與應用伺服主機要能夠互相操作，生理資訊能夠互相分享成為重要需求。本研究提出一個x73-PHD轉換器之設計，其目的在於作為醫療器材之代理者，收集來自醫療器材的生理量測值，並透過USB個人化健康器材類別介面傳送符合國際標準之11073資訊。本研究所提之x73-PHD轉換器是基於MSP430F5529晶片，以及ISO/IEEE 11073醫療器材標準規格所設計。以x73-PHD轉換器作為應用伺服主機及生理監測器之間的橋梁。x73-PHD轉換器收集來自生理監測器之生理量測資訊，並且將此些資訊轉換成符合ISO/IEEE 11073個人化健康器材相容之資訊格式。透過x73-PHD轉換器之USB PHDC介面，將此些標準化之生理資訊傳送到應用伺服主機。根據實驗結果，x73-PHD轉換器能成功收集及轉換TD-3250血壓計及血糖計之生理量測值，並且透過USB PHDC介面能與Continua所提供的標準應用伺服主機並交換生理資訊。

In the past years, the mechanism of equipment interoperability and information sharing between medical devices and application hosting devices was insufficient. Based on the number of elderly people in the population is rising, together with the rise of Health2.0 concept, there is a necessary need for intercommunication and exchange measurement data among the various medical devices and application hosting devices. The study proposes a design of the x73-PHD adaptor which as an agent of medical device, enabling the x73-PHD adaptor to collect the measured data and transmit them compliant with the international standard 11073 data format via a USB Personal Health Device Class (PHDC) interface. The design for the x73-PHD adaptor proposed in this paper is based on the MSP430F5529 and ISO/IEEE 11073 standards, which functions as a bridge between the application hosting device and the medical device. It converts vital sign data from the connecting medical device, and then transmits these data to the application hosting device in compliance with ISO/IEEE 11073 personal health device data format and protocol standards via the USB PHDC interface. Based on the testing results, the x73-PHD adaptor converts the measured data from the connecting medical device, TD-3250 blood pressure and blood glucose meter, and connect to Continua application hosting device to exchange healthcare information over the USB PHDC interface successfully.
