Description

Error history management system and method of bio / medical equipment using sensor tag}

The present invention relates to a bio / medical equipment abnormal history management system using a sensor tag, in particular, the environmental information that can know the temperature and humidity of the bio / medical equipment as well as the product information of the bio / medical equipment, the usage time of the lamp, etc. The sensor tag that senses, stores and transmits the stored information wirelessly is attached to the bio / medical equipment to manage the history of the bio / medical equipment. The present invention relates to a bio / medical equipment abnormal history management system and a method of using the sensor tag to solve the abnormality by applying to the inference process.

As is well known, electronic equipment in the bio or medical field is sensitive to temperature and humidity, and a function of maintaining a constant temperature or humidity is an important part, and thus, changes in temperature / humidity, constant temperature, It is necessary to continuously observe and store the bio / medical equipment's environmental information such as the humidity maintenance state and the lamp usage time, and not only determine the abnormality of the bio / medical equipment based on the environmental information, It becomes possible.

For example, an incubator that stores cells and blood is a device that needs to maintain a constant temperature and humidity. It stores temperature and humidity data inside such equipment to check temperature and humidity history at the time of regular inspection and consumable replacement. If possible, it is possible to check the equipment for abnormalities and to predict the failure that may occur in the future and to perform after-sales service.

In addition, constant temperature / humidity equipment used in clean rooms, cold rooms, GMP, clean rooms that require constant temperature / humidity will be a factor for diagnosing abnormality of equipment by checking temperature and humidity maintenance data.

There are many bioreagents and medicines that need to be stored at cryogenic temperatures (-80 ℃). Since these samples are easily deformed even with small temperature changes, there is a need for cryogenic refrigerators capable of maintaining a constant temperature. Deep freezers, such as large refrigerator systems, can affect samples even with slight changes in temperature, so there is a need for a method for predicting and diagnosing such failures in advance. And when a certain abnormal temperature is changed, the abnormality can be detected.

However, in order to collect and manage the environmental information of the equipment such as the important temperature, humidity, lamp usage time, etc., each device is equipped with a sensor and a memory to store the monitoring and environmental information with a separate processor in the equipment, and set standard It is not only necessary for a lot of costs to configure functions such as notifying abnormalities when abnormalities are changed, but also effective in integrating and managing the product information of each equipment, the above-described environmental information, and the history information according to the trouble and A / S. Therefore, there is a need for a bio / medical equipment abnormal history management system and an operation method capable of effectively acquiring, integrating, and managing abnormal history information including such environmental information.

In addition, a technique for managing the history of equipment or parts using an electronic tag has been proposed in the related art. As a representative example, Korean Patent Application Publication No. 113323 (Name of the Invention: Facility, Equipment and Parts Using RFID Electronic Tag) History management system (hereinafter referred to as 'cited invention').

For this reason, if the customer needs A / S, the technician will not be able to solve the problem immediately by visiting the basic information on the equipment. There is a problem that the after-sales cost increases.

The purpose of the present invention is to not only record the product information of the bio / medical equipment in order to solve this problem, but also to continuously detect the use time, temperature and humidity of the bio / medical equipment as environmental information and wireless transmission of the stored information By attaching a sensor tag to bio / medical equipment, it manages the abnormality monitoring and abnormal history of bio / medical equipment, and applies the history of bio / medical equipment to case-based reasoning process when abnormalities occur in such bio / medical equipment.
