"As healthcare related laws, payment terms and primary epidemic types are constantly changing each year, the demands for medical devices also change rapidly such that many hospitals are facing difficulties in the material excess or insufficient inventories. In addition, as unethical vendors still exist in the market, the purchase of medical devices with medical supply with qualified certification from the Ministry of Health and Welfare (MOHW) is still the basic requirement for the introduction of safe medical devices. However, since the quantity of medical devices is enormous, if informationization is not introduced for effective management, there is still a likelihood of the purchase of devices from unethical vendors. In addition, sterilization surgical instrument cover plates are also of the problem of validity period management. The question on how to use various application tools to prevent the erroneous use of expired products is also an important aspect of patient safety. Since the function of the existing information system is insufficient to cope with the aforementioned changes, this project needs to cope with the environmental changes in order to constantly correct and add information system along with the introduction of mechanisms of barcode technology, system automatic computation Big Data and active adjustment of purchase standards such that an all-round and quick responsive medical device management operation can be established to ensure patient safety.
