Maintenance of medical equipment has been changing rapidly in the past few years. It is changing more rapidly in developed countries, but changes are also occurring in developing countries. Some of the changes may permit improved maintenance on the higher technology equipment in developing countries, since they do not require onsite expertise. Technology has had an increasing impact on the development of medical equipment with the increased use of microprocessors and computers. With miniaturization from space technology and electronic chip design, powerful microprocessors and computers have been built into medical equipment. The improvement in manufacturing technology has increased the quality of parts and therefore the medical equipment. This has resulted in increased mean time between failures and reduced maintenance needs. This has made equipment more reliable in remote areas and developing countries. The built-in computers and advances in software design have brought about self-diagnostics in medical equipment. The technicians now have a strong tool to be used in maintenance. One problem in this area is getting access to the self-diagnostics. Some manufacturers will not readily provide this access to the owner of the equipment. Advances in telecommunications in conjunction with self-diagnostics make available remote diagnosis and repair. Since components can no longer be repaired, a remote repair technician can instruct an operator or an on-site repairman on board replacement. In case of software problems, the remote repair technician may perform the repairs over the telephone. It is possible for the equipment to be monitored remotely by modern without interfering with the operation of the equipment. These changes in technology require the training of biomedical engineering technicians (BMETs) to change. They must have training in computers and telecommunications. Some of this training can be done with telecommunications and computers.
在过去几年中,医疗设备的维护方式一直在迅速变化。在发达国家,这种变化更为迅速,但发展中国家也在发生变化。其中一些变化可能使发展中国家对高科技设备的维护得到改善,因为它们不需要现场专业知识。随着微处理器和计算机的使用增加,技术对医疗设备的发展产生了越来越大的影响。借助太空技术和电子芯片设计的小型化,强大的微处理器和计算机已被内置到医疗设备中。制造技术的进步提高了零部件的质量,进而提高了医疗设备的质量。这导致了平均无故障时间增加,维护需求减少。这使得设备在偏远地区和发展中国家更加可靠。内置的计算机和软件设计的进步带来了医疗设备的自我诊断功能。技术人员现在有了一个用于维护的强大工具。这一领域的一个问题是如何获得自我诊断功能。一些制造商不会轻易向设备所有者提供这种访问权限。电信技术的进步与自我诊断功能相结合,实现了远程诊断和维修。由于部件无法再修复,远程维修技术人员可以指导操作员或现场维修人员进行板件更换。在出现软件问题时,远程维修技术人员可以通过电话进行维修。通过现代技术可以在不干扰设备运行的情况下对设备进行远程监控。技术上的这些变化要求对生物医学工程技术人员(BMETs)的培训也随之改变。他们必须接受计算机和电信方面的培训。其中一些培训可以通过电信和计算机来完成。
