Reagents are used to detect, test, or quantify components of a substance in a variety of fields, including pharmacy, chemistry, biology, and medicine. The reagent may be a drug or a sample stored in a highly concentrated or high purity gaseous, solid, and liquid state, and which is very harmful to the human body or at risk of explosion.

The outer surface of the reagent container containing the reagent is attached with an optical cord for manufacturing and using one of bar code, QR code and optical character, the size of the optical code differs according to the manufacturer, and the width and height of the reagent container differ according to the manufacturer.

In the prior art, since the reagent carry-in / take-out person has to visually confirm and visualize the reagent in order to carry the reagent in and out, it takes a long time to take in and take out the reagent.

Conventionally, since a list of reagents prepared by hand is attached to a reagent storage cabinet for storing a reagent, there is a problem that it takes a long time to find a reagent necessary for a reagent carrier.

Patent Document 1 is directed to a reagent storage device and a reagent management system for managing the loading and unloading of reagents. The reagent storage device and the reagent management system are used to detect the optical code of the reagents in four directions using a plurality of image sensors or optical sensors, Thereby detecting optical codes in four directions.

Since the size of the optical code attached to the reagent vessel differs depending on the manufacturer and the width and the height of the reagent vessel differ depending on the manufacturer, the distance between the optical sensor and the optical code must be adjusted, Therefore, the light irradiation amount of the optical sensor must be adjusted, and since the optical sensor is fixed, the direction in which the reagent container is disposed and the direction of the optical sensor must match.

However, in Patent Document 1, there is a problem that the distance between the optical cords and the light irradiation amount can not be adjusted because the optical sensor is fixed, and there is a problem that the direction in which the reagent vessel is arranged needs to be arranged by the reagent carrier. There is a problem that the mounting cost of the sensor is increased.

Patent Document 1 disadvantageously discriminates a reagent by detecting a manufacturing use optical code attached to a reagent vessel, but has a problem that it is difficult to use the code as a self-managing code in a reagent management system.

The manufacturing use optical code may be one of a bar code, a QR code, and an optical character, and the management optical code 11 may be a QR code, but is not limited thereto.

The barcode is a one-dimensional code, the QR code is a two-dimensional matrix-based code, and the optical character is machine-encoded text. The one-dimensional barcode can store only about 20 characters of numerical information, while the QR code can store about 7,089 characters of numerical information or about 4,296 characters of character information.

When the exporter / importer wishes to take out or carry out the reagent, the sliding shelf in which the reagent container is stored is moved, and the storage position is indicated by an LED-like light, so that it can easily be carried out or brought in. Also, since the weight or the remaining amount of the reagent is automatically detected by the take-out and putter, it is not necessary to write it manually or require a separate input.

Referring to FIG. 4, the reagent management method receives a selection input of a drawer from an input unit, and determines whether the reagent is carried in or out corresponding to a selection input in the drawer determining unit 150.

The reagent management device can receive a selection input for the identification information of the carry-in / out person from the input section, display the identification information of the carry-in / out person from the display section, compare the identification information previously stored in the input / It is possible to determine whether access is made or not.

When the reagent management apparatus is determined to be allowed access, the input / output unit can receive a selection input for loading or unloading the reagent from the input unit, and the loading / unloading unit can determine whether the reagent is loaded or unloaded corresponding to the selection input.

When the reagent management device determines the loading or unloading of the reagent, the method of loading or unloading from the display part may be indicated to be provided to the unloading / dispensing device, and the unloading / unloading device may be performed in correspondence with the method of loading / unloading indicated on the display part .

In the reagent management method, when the reagent is brought in, the reagent management device senses the management optical code including the management information attached to the reagent container through the fixed optical sensor, reads the management information, The sliding shelf is moved and moved up and down through the movable optical sensor to sense the optical code for maintenance and the storage position. The capacity indicator of the reagent is sensed through the movable optical sensor to detect the remaining amount of the reagent. The management information is updated with reference to information on the remaining amount of the reagent.

When the reagent management device senses the storage position, the sliding shelf corresponding to the management information is moved through the sliding sensor, the storage position where the reagent container is stored, and the storage position in contact with the reagent container .

If the reagent management method is to take out the reagent, the reagent management device moves the sliding shelf corresponding to the management information included in the selection input through the sliding sensor, displays the storage position where the reagent container is stored, Detects the optical code for management through the fixed optical sensor to confirm the carry-out, and updates the management information by referring to the information about the selection input or the withdrawal of the reagent.

In the reagent management method, the reagent management device records the internal and external environments of the cabinet through the optical sensor for recording to generate recording information, and the recording information can be transmitted to the administrator terminal or the reagent monitoring server in real time in the local communication section.

The reagent monitoring server can be connected to the local communication section of the reagent management apparatus by being connected to the wired / wireless gateway.
