The operation of the accommodation chamber 2 from the locked open state to the locked closed state can be performed regardless of the drive of the solenoid unit 17. Further, the operation from the locked closed state to the locked open state is possible by driving the solenoid unit 17 and retracting the plunger 16.

Next, the eaves mechanism 20 provided at the front portion of the guide frame 10 will be described with reference to FIGS. 4A and 4B.
FIG. 4A is a cross-sectional view of the eaves mechanism 20 with the storage chamber 2 closed, and FIG. 4B is a cross-sectional view of the eaves mechanism 20 with the storage chamber 2 open.
As shown in FIG. 2, in the front portion of the guide frame 10, stay members 21 having a U-shaped cross section are extended in the lateral direction for each step (two steps in the drawing) of the accommodation chamber 2. The eaves mechanism 20 is attached along the stay member 21.

As shown in FIGS. 4A and 4B, the eaves mechanism 20 has an eaves body 22 formed of, for example, a rubber resin in an inverted U-shaped cross section having a groove 22a. The groove portion 22a of the eaves main body 22 extends along the width direction of the corresponding accommodation chamber 2, and can be locked to the upper end portion of the front wall 2a1 of the accommodation chamber main body 2a as shown in FIG. 4A. ing. In the state shown in FIG. 4A, the eaves main body 22 covers the gap between the guide frame 10 and the accommodation chamber 2 to prevent foreign matter and the like from entering.

The upper part of the eaves main body 22 is rotatably supported by a shaft pin 26 fixed to the guide frame 10 (housing side), and the eaves main body 22 is rotatable in the front-rear direction (clockwise direction, counterclockwise direction). It is provided in.
Further, in the groove portion 22a of the eaves main body 22, the lower end of the rear portion 22a2 is formed longer than the lower end of the front portion 22a1.
As a result, when the accommodation chamber 2 is pulled forward, the eaves main body 22 rotates around the shaft pin 26, and the groove portion 22a of the eaves main body 22 is easily removed from the upper end of the front wall 2a1n (the front wall 2a1 is the eaves main body). It is configured to be away from 22).

Further, as shown in FIGS. 4A and 4B, the eaves main body 22 is fixed to a plate-shaped fixing bracket 23 on the back side thereof, and one end of a compression spring 24 (elastic means) is fixed to the fixing bracket 23. Is fixed. On the other hand, the other end of the compression spring 24 is fixed to the screw fastening projection 27 formed on the stay member 21 by a screw 28.
As a result, the urging force of the compression spring 24 is always applied in the direction of rotating forward with respect to the back surface side of the eaves main body 22 (clockwise in FIG. 4A).

Further, in the fixing bracket 23, a plate-shaped protrusion 23a that projects rearward with a predetermined lateral width is formed at the upper end of the surface on which one end of the compression spring 24 is fixed. The plate-shaped protrusion 23a functions as a so-called stopper that stops the rotation of the eaves main body 22.
Further, a plate-shaped protrusion 23b is formed on the lower end side of the surface to which one end of the compression spring 24 is fixed so as to project rearward with a predetermined vertical width.
The plate-shaped protrusion 23b rotates together with the eaves main body 22 and functions as a detection shielding portion for detecting the open / closed state of the accommodation chamber 2.
That is, an interrupter sensor (light emitting element, light receiving element) 23c for detecting the state of the storage chamber is provided on the lower surface of the stay member 21, and when the plate-shaped protrusion 23b blocks the interrupter sensor 23c, it is stored. When the chamber is closed, the storage chamber is detected when it is not shut off.

In the eaves mechanism 20 configured in this way, when the accommodation chamber 2 is closed as shown in FIG. 4A, the groove portion 22a of the eaves main body 22 covers the upper end portion of the front wall 2a1 of the accommodation chamber main body 2a. Engage in state.
When the accommodation chamber 2 is pulled out from that state, the eaves main body 22 rotates clockwise with the shaft pin 26 as a fulcrum due to the urging force of the compression spring 24, and the engagement between the eaves main body 22 and the accommodation chamber main body 2a is released. Will be done. As shown in FIG. 4B, the rotation of the eaves main body 22 is stopped when the plate-shaped protrusion 23a of the fixing bracket 23 comes into contact with the stay member 21.

Further, as shown in FIG. 4B, when the accommodation chamber 2 is pushed in the direction of closing from the open state, the upper end of the front wall 2a1 of the accommodation chamber 2 hits the lower end of the rear portion 22a2 of the eaves main body 22. In contact with each other, the eaves main body 22 is rotated in the upright direction (counterclockwise direction) against the urging force of the compression spring 24.
When the accommodation chamber 2 is completely closed as shown in FIG. 4A, the upper end portion of the front wall 2a1 of the accommodation chamber 2 engages with the groove portion 22a of the eaves main body 22, whereby the rotation position of the eaves main body 22 is changed. It is fixed.

Subsequently, the system configuration of the medication cart 1 will be described with reference to the block diagram of FIG. As shown in FIG. 5, the medication cart 1 matches between the control unit 7a (control means) that performs various calculations in the computer device 7 and the pattern in which the vein pattern detected by the vein detection sensor 6 is registered in advance. It has a biometric authentication unit 7b (biometric authentication means) and a storage unit 7c (storage means) for storing various data.

A code input unit 11 and a display unit 13 are connected to the computer device 7, and by inputting a management code of each patient from the code input unit 11, medical record information including prescription drug information, disease name, and the like can be obtained. It is displayed on the display unit 13. The management code is a code consisting of a plurality of digits in which alphanumeric characters and symbols are combined, and has been conventionally used in hospitals to identify patients.
Further, for example, the opening / closing control of the electromagnetic lock mechanism 15 can be controlled by inputting the password using the code input unit 11 regardless of the biometric authentication using the vein detection sensor 6 so that the administrator can open / close the electromagnetic lock mechanism 15. It may be configured so that it can be done.

Further, in the storage unit 7c in the computer device 7, vein data of a patient (authorized user) registered in advance is recorded, and a management code for identifying the patient and corresponding medical record information (patient name, Gender, age, drug information), alarm setting time information for notifying the drug administration time, etc. are stored.

The patient's vein data (biometric data) registered in the storage unit 7c and the patient-related data can be deleted according to the flow shown in FIG. That is, for example, a menu screen is displayed on the display unit 13, and the operator selects the deletion start button in the menu screen (step SP1).

Next, enter information such as the registration management code, first and last name, gender, and age (step SP2). The computer device 7 determines whether the input information such as the management code is correct and can be deleted (step SP3), and if it can be deleted, the operator selects the delete button (step SP4). As a result, the data related to the patient registered in the storage unit 7c is deleted.

Further, the computer device 7 is LAN-connected (wired or wirelessly connected) to the management server 25 (computer) located at a location away from the medication cart 1.
In general, in hospitals, the patient's medical record information and the like are held and managed by the management server 25 in association with the management code, but when registering the vein data of the patient, the management code for identifying the patient is used. By associating, the vein data and the medical record information stored in the management server 25 can be automatically associated. That is, it is not necessary to newly input the medical record information corresponding to the vein data of the registered patient.

In addition, once the patient's medical record data and the medical record information in the management server 25 are linked, the patient's medical record information is authenticated by holding the palm over the vein detection sensor 6 for future use. Can be read from the management server 25 side to the computer device 7 (the medical record information does not have to be stored in the storage unit 7c).

Further, since the computer device 7 and the management server 25 are connected to each other via a LAN, it is not always necessary to store the patient's vein data, medical record information, etc. in the storage unit 7c, and all the data related to the patient is stored in the management server 25. It may be configured to be managed by.
When the storage unit 7c and the management server 25 store the data of the same item of the same patient, the specifications are such that the synchronization process is automatically performed periodically or when one of the data is updated. There is.
Further, when the operation of deleting the patient data from the storage unit 7c described above is performed, even if the data related to the patient is deleted from the storage unit 7c, the related data of the patient registered in the management server 25 is not deleted. , May be left.

Further, the control unit 7a detects the open / closed state of the door (storage chamber) including the electromagnetic lock mechanism 15 including the plunger 16 and the solenoid unit 17 described above, the plate-shaped protrusion 23b and the interrupter sensor 23c described above. The door open / close sensor 29 is connected. In the door open / close sensor 29, when the plate-shaped protrusion 23b blocks the interrupter sensor 23c, the storage chamber is closed, and when it is not shut off, the storage chamber is open. To detect.
The detection result by the door open / close sensor 29 is sent to the control unit 7a, and the control unit 7a is configured to control the lighting and extinguishing of the LED lighting unit 12 based on the detection result.

Subsequently, based on the flow of FIG. 6, a process related to drug administration to one patient in the drug administration cart 1 will be described.
For example, when giving medicine to a hospitalized patient, the nurse in charge pushes the medicine cart 1 to the hospital room where the patient is hospitalized and moves it. The nurse stops the medication cart 1 next to, for example, the patient's bed.
When the door open / close sensor 29 detects that any of the plurality of accommodation chambers 2 is open before pulling out the accommodation chamber 2 corresponding to the patient, the LED lighting unit 12 corresponding to the open accommodation chamber 2 is activated. Lights up (step S1).
The nurse confirms the open containment chamber 2 and closes it (step S2). As a result, the medication cart 1 is in a state in which the vein authentication process can be operated, and after the predetermined authentication start setting is performed, the palm of the patient (user) is placed on the vein authentication sensor 6. As a result, in the computer device 7, the authentication process by matching the read vein pattern is started (step S3).

If the authentication result is OK within a predetermined time (for example, 20 seconds) with the palm placed on it (steps S4 and S5), the electromagnetic lock mechanism 15 of the containment chamber 2 linked to the matching pattern of the vein patterns is the plunger. The engagement between 16 and the lock metal fitting 2c is released (step S6).

Further, the extrusion pin 19 pushes the storage chamber 2 forward by a predetermined distance. As a result, the door open / close sensor 29 detects the open state of the accommodation chamber 2, and the LED lighting unit 12 corresponding to the accommodation chamber 2 lights up in blue, for example (step S7).
Further, the computer device 7 records the time information when the accommodation chamber 2 is opened in the storage unit 7c (step S8).

The nurse takes out the prescribed drug corresponding to the time zone (for example, for daytime) from the open containment chamber 2 and administers the drug to the patient who has undergone vein recognition. This administered drug is in the containment chamber 2 linked to the patient given it by biometric authentication, and the containment chamber 2 automatically pops out and opens forward after biometric authentication, even when the LED is lit. Since the containment chamber 2 can be easily identified, the nurse can undoubtedly administer the drug to the relevant patient.

When the medication is completed, the nurse pushes in the containment chamber 2 to close it, whereby the electromagnetic lock mechanism 15 automatically locks the containment chamber 2 (step S9).
Further, as a result, the door open / close sensor 29 detects the closed state of the accommodation chamber 2, and the LED lighting unit 12 corresponding to the accommodation chamber 2 is turned off (step S10). Further, the computer device 7 records the time information when the accommodation chamber 2 is closed in the storage unit 7c (step S11).
In step S4 after the start of vein authentication, after a predetermined time (for example, 20 seconds) has elapsed, the process ends with the LED turned off as an authentication operation start failure.

As described above, according to the first embodiment of the present invention, when the security box device of the present invention is applied to a medication cart, the drug to be administered to the patient who has been intravenously authenticated by the nurse is the same. It is in the containment chamber 2 that is associated with the patient to be given by biometric authentication, and the containment chamber 2 automatically pops out and opens forward after the biometric authentication, and the containment chamber 2 can be easily identified by lighting the LED. This allows nurses to undoubtedly give medication to the patient in question.
Further, since the patient's vein pattern and the patient's management code are associated with each other, the patient can easily refer to the medical record information or the like associated with the management code in advance by performing vein authentication.

Subsequently, the second embodiment according to the present invention will be described. FIG. 7 is a view in which the security box device of the present invention is applied to a door opening / closing type cabinet, and is a perspective view showing a second embodiment of the present invention. 8 is a perspective view of the cabinet of FIG. 7 with the door open.
