[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention allows unauthorized use of reagents stored in medical institutions and various research facilities only by specific persons, and collectively manages necessary data such as the amount of used reagents and whether or not they are returned. The present invention relates to a management system for reagents in containers that not only prevents taking out and contributes to improvement of safety, but also allows a user to unify the usage status and stock status of various reagents. The term “reagent” as used herein refers to chemicals of high purity and constant quality that are used on a relatively small scale, such as for education, research, and testing, and for analysis and synthesis. Drugs used for treatment and prevention and chemicals such as high-risk poisons and explosives should also be included.

[0002]

[Prior art]

 Since various reagents including powerful drugs tend to be dangerous when they are used, it is common that the reagents are conventionally stored in bottles safely in bottles. Moreover, the storage is often provided with a security structure that allows only a specific person having a key or an ID card to access the storage.

[0003]

[Problems to be solved by the invention]

 However, in the case of the above-mentioned conventional system, there is a disadvantage that a reagent in a bottle can be easily taken away by an unauthorized outsider as long as the person possesses a key or an ID card. In addition, there is a problem that even if a person who possesses a key or an ID card is a genuine person, the person can arbitrarily take it outside.

[0004] The present invention has been made in view of the above-mentioned problems encountered in the conventional system, so that only registered persons can use the reagent, and furthermore, the type and amount of the reagent can be managed strictly in a unified manner and safely managed. It is an object of the present invention to provide a system for managing a reagent contained in a container.

[0005]

[Means for Solving the Problems]

 The present invention has been made to achieve the above object, and the feature of the configuration is that manual unlocking and locking using a key for opening and closing operation are freely formed, and the key is operated. A reagent storage provided with a lock mechanism that emits a warning sound depending on the user, and whether a person who operates the key of the reagent storage has a magnetic card assigned only to a specific registrant is determined. A magnetic card reader for identification, a barcode scanner for reading and identifying the reagent in the container taken out of the reagent storage from the barcode label attached to the container, and an electronic balance for weighing the reagent in the container. A warning sound is issued only when the person who operates the lock mechanism of the reagent storage key is a non-owner of the magnetic card and the unlocking is not permitted, and a warning is issued when the user is the owner of the magnetic card. Emit sound The reagent storage is allowed to be unlocked without being used, the reagent name of the removed reagent in the container, and the amount of reagent calculated based on the weight before and after use of the reagent weighed by the electronic balance, etc. And at least a central processing unit that is freely arranged to display the necessary data and to register various data related to the reagents used.

In this case, it is preferable that the barcode label has a unique barcode individually assigned by a user for each registered reagent. Further, it is preferable that the central processing unit is provided with a keyboard having a numeric keypad which is freely arranged for inputting a password for double-checking that a holder of the magnetic card is a registrant. Further, it is preferable that the key be stored in a key box that can be opened and closed only by the magnetic card provided to the registrant.

[Embodiment of the invention]

 FIG. 1 is a schematic explanatory view showing an example of a system configuration of the present invention. As a whole, a reagent storage 11 with a lock mechanism 12 for storing various kinds of reagents 14 in a container, and a reagent storage 11 A magnetic card reader 21 for identifying whether or not a person who operates the lock mechanism 12 using the key 13 is a person who possesses a magnetic card 22 assigned only to a specific registrant, and taken out of the reagent storage 11. A bar code scanner 17 for reading and specifying the reagent 14 contained in the container from a bar code label 16 attached to the container 15, an electronic balance 23 for weighing the reagent 14 contained in the container, and a personal computer 32 of, for example, 32 bits. And a central processing unit 31 having a keyboard 33 with a numeric keypad and having overall control of the entire system.

In this case, the system includes a barcode label printer 25 that can individually apply a unique barcode to each registered reagent at the user's site, and further includes a magnetic card 22 attached to the registrant. It is preferable that the key 13 can be stored in the key box 18 whose opening and closing can be controlled by reading the key 13 with a magnetic card reader 18a.

Among them, the reagent storage 11 has a buzzer which can be manually unlocked and locked using the key 13 for opening and closing operation, and which emits a warning sound by a person who operates the key 13. Is provided with a lock mechanism 12 provided with a lock mechanism. In addition, a bar code label 16 is separately affixed to the side of the container 15 formed of, for example, a glass bottle in the plurality of containers 14 stored in the reagent storage 11, and the bar code label 16 is fixed. A specific reagent name can be specified by reading using either the barcode scanner 17 of the portable scanner 17a or the portable scanner 17b.

Further, the magnetic card reader 21 is provided with a magnetic card 22 provided in advance to identify a specific registrant who is permitted to use the reagent 14 contained in the container stored in the reagent storage 11. By reading the information, it is possible to determine whether the holder of the magnetic card 22 is a registered person or a non-registered person. In this case, the magnetic card 22 stores various necessary data that can identify an individual, such as affiliation and ID number, in the form of a magnetic stripe, in addition to various personal attributes such as name and gender.

The electronic balance 26 is for weighing the reagent 14 contained in a container, and measures the weight before and after use to determine the actual usage amount and the remaining amount of the reagent. Can be used.

On the other hand, the central processing unit 31 emits a warning sound and permits unlocking only when the person who operates the lock mechanism 12 of the reagent storage 11 using the key 13 is a non-holder of the magnetic card 22. If the holder of the magnetic card 22 does not emit a warning sound, control can be performed to permit unlocking of the reagent storage 11. The personal computer 32 that constitutes the central processing unit 31 stores the reagent calculated based on the reagent name of the removed reagent 14 in the container and the weight before and after use of the reagent weighed by the electronic balance 26. A screen (CRT) 32a for displaying necessary data such as the actual use amount of the reagent is provided, and various data including the history relating to the used reagent can be freely written and read into an appropriate memory. I have. The personal computer 32 is provided with a printer (not shown) so that necessary data can be printed out.

FIG. 2 is a flowchart illustrating an example of a processing procedure for removing a reagent contained in a container, which is performed using the above-described system. In this system, as a preparatory work, persons who have been permitted to use reagents must be individually registered in the magnetic card 22 and each authentic registrant must have the magnetic card 22 individually. Is assumed. In the reagent 14 in the container, necessary data such as the name and initial weight are registered in advance. Further, a bar code label 16 attached to the container 15 of the reagent 14 in the container is individually provided with a unique bar code by a user by a bar code label printer 25 constituting a part of the system. Can be used.

That is, according to FIG. 1, a person who takes out and uses the reagent 14 contained in the container in the reagent storage 11 makes the magnetic card reader 21 read the magnetic card 22 possessed by the user, and registers the authentic registration. Is determined. If it is determined that the user is a genuine registrant, data indicating that the registrant (user) has used the system at that date and time (such as the registrant's name and ID number) is registered. You. If it is determined that the user is not a registrant, an error is displayed on the screen (CRT or LCD) 32a, for example, and the process is terminated. In this case, the authentic registrant may be double-checked by inputting a password using the numeric keypad of the keyboard 33 in addition to the magnetic card 22.

After the registration is completed and it is determined that the user is a genuine registrant, the key box 18 is automatically unlocked and the key 13 can be taken out. The unlocking operation of the lock mechanism 12 is performed. At this time, when a person who possesses the key 13 (for example, a finder who has no justifiable reason) who has not passed the registrant discriminating process uses the key 13 to unlock the lock mechanism 12, A buzzer provided in the lock mechanism 12 sounds and emits a warning sound to notify the surroundings that the person is not a genuine person.

After the reagent 14 in the specific container is taken out of the reagent storage 11, the bar code label 16 attached to the container 15 determines whether the fixed scanner 17 or the portable scanner 17 b The barcode data is read using the barcode scanner 17 and registered in the central processing unit 31, and the lock mechanism 12 of the reagent storage 11 is locked to complete the removal process of the reagent 14 contained in the container. . If the reagent has been registered, the name of the reagent is displayed on the screen (CRT or LCD) 32a. If necessary, the attributes of the reagent (eg, chemical formula, toxicity, melting point, boiling point) Odor, color, etc.) and precautions for use can also be displayed.

On the other hand, FIG. 3 is a flowchart showing an example of a processing procedure when taking out the reagent 14 contained in the container, returning it after finishing its use.

According to FIG. 1, a magnetic card reader 21 is caused to read a magnetic card 22 possessed by the user and determine whether or not the user is a genuine registrant. When it is determined that the user is a genuine registrant, data (name, ID number, etc. of the registrant) relating to the registrant (user) is registered. If it is determined that the user is not a registrant, an error is displayed on the screen (CRT) 32a, for example, and the process is terminated. In this case, the genuine registrant may be confirmed by a double check by inputting a personal identification number using a numeric keypad of the keyboard 33 in addition to the confirmation by the magnetic card 22.

After completing the above-mentioned registration, the bar code label 16 affixed to the container 15 of the reagent 14 in the container that has been taken out is used to read one of the fixed scanner 17 and the portable scanner 17 b. Then, the data is read using and the data is registered in the central processing unit 31.

Next, the taken-out reagent 14 in the container is weighed using the electronic balance 26, and necessary data such as date and time, user name, reagent name, used amount, and remaining amount are registered in the central processing unit 31. I do.

After the registration of the necessary data is completed, the magnetic card 22 possessed by the registrant is read by the magnetic card reader 18a of the keyboard 18, and it is determined whether or not the registrant is a genuine registrant. At this time, if it is determined that the user is a genuine registrant, the key box 18 is automatically unlocked and the key 13 can be taken out, and the key 13 is used to lock the lock mechanism 12 of the reagent storage 11. Can be unlocked again. Also, when a person who has the key 13 unlocks the lock mechanism 12 using the key 13 for no good reason, the buzzer provided in the lock mechanism 12 sounds and an alarm sounds. It emits and informs others that you are not authentic.

After the lock mechanism 12 of the reagent storage 11 is unlocked by the genuine registrant, the used reagent 14 in the container is returned to the reagent storage 11 and the key 13 is operated to lock the reagent. The mechanism 12 is locked, and the key 13 is returned into the key box 18 to terminate the processing.
