Advances in medical devices and health care has been phenomenal during the recent years. Although medical device manufacturers have been improving their instruments, network connection of these instruments still rely on proprietary technologies. Even if the interface has been provided by the manufacturer (e.g., RS-232, USB, or Ethernet coupled with a proprietary API), there is no widely-accepted uniform data model to access data of various bedside instruments. There is a need for a common standard which allows for internetworking with the medical devices from different manufacturers. ISO/IEEE 11073 (X73) is a standard attempting to unify the interfaces of all medical devices. X73 defines a client access mechanism that would be implemented into the communication controllers (residing between an instrument and the network) in order to access/network patient data. On the other hand, MediCAN™ technology suite has been demonstrated with various medical instruments to achieve interfacing and networking with a similar goal in its open standardization approach. However, it provides a more generic definition for medical data to achieve flexibility for networking and client access mechanisms. The instruments are in turn becoming more sophisticated; however, the operation of an instrument is still expected to be locally done by authorized medical personnel. Unfortunately, each medical instrument has its unique proprietary API (application programming interface - if any) to provide automated and electronic access to monitoring data. Integration of these APIs requires an agreement with the manufacturers towards realization of interoperable health care networking. As long as the interoperability of instruments with a network is not possible, ubiquitous access to patient status is limited only to manual entry based systems. This paper demonstrates an attempt to realize an interoperable medical instrument interface for networking using MediCAN technology suite as an open standard.
近年来，医疗设备和医疗保健领域取得了显著进展。尽管医疗设备制造商一直在改进他们的仪器，但这些仪器的网络连接仍然依赖专有技术。即使制造商提供了接口（例如，RS - 232、USB或与专有API耦合的以太网），也没有广泛接受的统一数据模型来访问各种床边仪器的数据。需要一种通用标准，以实现与不同制造商的医疗设备进行网络互联。ISO/IEEE 11073（X73）是一项试图统一所有医疗设备接口的标准。X73定义了一种客户端访问机制，该机制将被实现到通信控制器（位于仪器和网络之间）中，以便访问/联网患者数据。另一方面，MediCAN™技术套件已在各种医疗仪器上得到验证，以其开放标准化方法实现类似目标的接口和联网。然而，它为医疗数据提供了更通用的定义，以实现网络和客户端访问机制的灵活性。仪器本身变得越来越复杂；然而，仪器的操作仍期望由授权医务人员在本地完成。不幸的是，每个医疗仪器都有其独特的专有API（应用程序编程接口 - 如果有的话），以提供对监测数据的自动化和电子访问。集成这些API需要与制造商达成协议，以实现可互操作的医疗保健网络。只要仪器与网络的互操作性无法实现，对患者状态的普遍访问就仅限于基于手动输入的系统。本文展示了一种尝试，即使用MediCAN技术套件作为开放标准来实现用于网络的可互操作医疗仪器接口。
