Develop medical device communication and rectify health care system

Release date: 2009-03-09

At present, the standards of medical devices vary from country to country, making the same medical devices not common among different countries, let alone data sharing. And if an international standard is established, it will help data transmission and communication between different medical devices around the world, and improve the efficiency and flexibility of health care professionals. Previously, the Institute of Electrical and Electronics Engineers predicted that technology power is the next frontier in the global healthcare industry.
So, what is the problem with data transmission between medical devices? What problems should be solved in the standardization of medical device communication methods? What changes will be brought to people's medical health? A few days ago, the reporter interviewed Dr. He Bin, Chairman of the Institute of Biomedical Engineering of the American Institute of Electrical and Electronics Engineers, and Professor Zhang Yuanheng, Director of the Joint Research Center of Biomedical Engineering of the Chinese University of Hong Kong.
The lack of medical network systems limits patient mobility The reporter learned that establishing and developing healthcare industry standards is a focus of the Institute of Electrical and Electronics Engineers in this area. They work with a variety of public and private international organizations, including ensuring a reliable healthcare network, promoting personalized healthcare information, promoting wireless healthcare communications, telepresence technology in healthcare information technology, and standardized electronics. Health records and interoperability between critical patient care medical devices.
Speaking of the health care network, Professor Zhang Yuanheng believes that China is currently trying to integrate with the international community. Large hospitals, especially the top three hospitals, have established communication networks, and data can be transmitted quickly over the Internet. However, community hospitals and private hospitals other than the top three hospitals have not established such a medical network system, which is not conducive to the treatment of patients because of the problem of mobility.
Different medical device standards Data is difficult to share The first level of establishing and developing health care standards is the establishment of data transmission standards between medical devices. The establishment of this international standard helps data transmission and communication between different medical devices around the world, improving the efficiency and flexibility of healthcare professionals.
Professor Zhang Yuanheng talked about another level and his current research focus, that is, establishing international standards to judge the accuracy of data collected by medical devices. Zhang Yuanheng gave an example of a project "continuous sphygmomanometer" he was studying. "Continuous sphygmomanometer" is a new type of blood pressure measurement method. We use the old sphygmomanometer to measure that we only get two blood pressure values, high value and low value, but using a "continuous sphygmomanometer", we can get multiple high blood pressure values ​​and Low values, and their average value, thus improve the accuracy of the measurement.
Zhang Yuanheng believes that to achieve this goal, it is necessary not only to work with experts in health care to study the operating standards of this new type of sphygmomanometer, but also to discuss with the enterprise the difficulties that may be encountered in actual manufacturing.
Standardization of medical device communication methods What is the problem?
Dr. He Bin believes that the standardization of medical device communication methods, or the data transmission methods of medical devices, can solve three problems in the international healthcare industry.
The first is to resolve the unevenness. The standardization of data transmission methods enables different manufacturers and different types of medical device systems to interoperate, eliminating the need for special converters or adapters during data sharing.
The second is to achieve semantic comparability. Today, most medical devices are using incompatible proprietary languages, which are different communication standards. Standardization of communication methods will enable seamless integration of data from different medical devices, which will greatly simplify the procedures for electronic health records and clinical decision systems, and increase the flexibility and functionality of the system.
The third is that standardization of communication methods will reduce the complexity of the entire healthcare system, increase the likelihood of real-time treatment, and the amount of information. In other words, health care workers can make more timely care decisions based on richer medical data. Ultimately, patient safety will be greatly improved, the quality of care will be greatly improved, and the cost of care will be reduced. The resolution of all these issues will have a positive impact on people around the world.
Todd Cooper, a senior member of the Institute of Electrical and Electronics Engineers and president of the IEEE 11073 Fixed Care Medical Device Communications Association, previously said, "The idea stems from the convergence of technology that contributes to the advancement of global patient care services. Such data sharing can be for healthcare. Experts offer greater flexibility to work closely together and use important medical data to save patients' lives."
Standardization implementation requires all parties to cooperate. Experts believe that the standardization of medical device communication methods requires the cooperation of hardware and software. For existing medical devices, standard conformance will be achieved by replacing the necessary hardware and software systems. The new medical device will standardize the communication method by installing a software system.
The specific implementation of the standardization of medical device communication methods requires the joint efforts of health care experts, manufacturers, IT engineers and the government to work together.
For example, Zhang Yuanheng said that if manufacturers feel unprofitable, they are reluctant to produce new types of medical devices. Therefore, as a research and development medical expert and IT engineer, efforts must be made to make this concept realistic and operational. The government's support, especially the investment in research and development funds and resources, will greatly accelerate the realization and popularization of medical device communication methods.
He Bin said that the current focus is to develop protocols and standards for all medical device communications to improve communication efficiency. The development of this agreement and standards depends on the input and professional organization of governments. Meditech Medical Network
