Figures 1 to 3 are diagrams showing a drawer-type medicine storage device according to the present invention, and Figure 4 is a diagram showing a medicine storage cassette inserted and fixed into the medicine storage device shown in Figure 1.

Referring to Figures 1 to 4, the medicine storage device 1 according to the present invention is a device for storing medicines, and medicines may include various forms and types of medicines and medical devices.

The medicine storage device 1 may be a drawer type including a drawer 10 in which medicines are stored. For example, the medicine storage device 1 includes a first drawer 10-1 and a first drawer 10-1. A three-stage system including a second drawer (10-2) located below the lower part (10-1) and a third drawer (10-3) located below the second drawer (10-3). It may be a drawer type, but is not necessarily limited to this, and may be designed to include a various number of drawers.

A medicine storage cassette 100 storing medicines can be inserted and fixed into the internal space of each drawer 10, and the medicine storage cassette 100 can have various sizes, such as the size shown in FIG. 4. there is.

The medicine storage device (1) may have administrator access rights to medicines set so that the situation such as input, storage, and discharge of medicines can be checked in real time, and only managers with certified access rights can discharge or replenish medicines. This may be possible.

The manager can check the status of input, storage, and discharge of medicines in real time through the software execution screen displayed on the display 30, or enter control commands for the medicine storage device 1 for discharge or replenishment of medicines. .

Here, the executing software may be software for controlling the medicine storage device 1 for controlling the withdrawal of the drawer 10 and the opening and closing part 120 of the medicine storage cassette 100 for discharging or replenishing medicine.

When a prescription is received and a medicine storage device (1) containing medicine to be discharged is selected, the manager certifies whether he or she has the authority to discharge medicine from the medicine storage device (1). As shown in the example shown in FIG. 2, the second drawer (10-2) equipped with the medicine storage cassette 100 containing medicines that can be discharged among the plurality of drawers is indicated with an indicator light, and the manager uses the second drawer. After unlocking (10-2) with the proximity sensor 40-1 or button 40-2, it can be pulled out from the frame 20, and when the second drawer 10-2 is pulled out, it is shown in FIG. 3 As shown, the opening/closing portion 120 of the medicine storage cassette 100 accommodating the medicine is automatically rotated to open the storage space where the medicine is stored.

The environment in which the manager can perform normal work for normal drug discharge is called normal mode, and the environment in which normal drug discharge cannot be performed is called emergency mode. At this time, in emergency mode, the drawer (10) The drawer 10 may be designed to change from a locked state to an unlocked state in which it can be withdrawn only when the withdrawal lock device (not shown) of the drawer 10 is released. The withdrawal locking device of the drawer 10 may be designed to unlock all drawers 10 at once, and may be implemented as a key or lever type at the bottom or side of the medicine storage device 1.

The principle of opening the storage space by automatically rotating the opening/closing unit 120 will be described in detail with reference to FIGS. 6 and 7.

Meanwhile, when the replenishment or discharge of medicine is completed after the storage space is opened, the manager applies an external force so that the opening and closing part 120 is rotated to change into a fully locked state in which the storage space is completely closed, and then the second device drawn out is applied. The lower (10-2) is hidden within the frame (20).

Here, the medicine storage cassette 100 according to the present invention was intended to hide the second drawer 10-2 after the manager applied external force and changed it to a fully locked state, but the size of the external force was unintentionally insufficient. Thus, even if the state fails to change to the fully locked state (see FIG. 5), the incompletely locked state (see FIG. 8) can be maintained.

As a result, when the second drawer (10-2) is hidden in the frame 20 and then withdrawn, the incomplete locking state is maintained, so that the opening and closing unit 120 is not caught in the first drawer (10-1), thereby preventing the opening and closing unit from being caught in the first drawer (10-1). Damage of (120) can be prevented.

The incomplete locking state will be described in detail with reference to FIG. 8.

Figure 5 is a diagram for explaining the fully locked state of the medicine storage cassette according to the present invention.

Referring to Figure 5, the medicine storage cassette 100 according to the present invention is a type of medicine that is inserted and fixed into the inner space of the drawer 10 of the drawer-type medicine storage device 10 shown in Figures 1 to 3. It is a box for storing and may include a main body 110, an opening and closing part 120, and a locking part 130.

The main body 110 may provide a storage space for storing specific medicines, and may be formed in a roughly hexahedral shape, but is not necessarily limited thereto.

The opening and closing part 120 may be rotatably connected to the main body 110 to open and close the storage space.

Specifically, the opening and closing part 120 is rotatably connected to the upper side of the main body 110, and is located on the side in the direction in which the second drawer 10-2 is hidden in the frame 20, that is, of the main body 110. It can be rotatably connected to the rear side of the upper side.

The opening and closing part 120 can be opened from the front of the upper side of the main body 110 when the storage space is opened by the locking part 130 (see FIGS. 6 and 7).

The locking unit 130 may be a component mounted on the main body 110 to maintain the closed state when the storage space is closed by the opening and closing unit 120.

The locking unit 130 has a rotating unit 132 rotatably mounted on the main body 110, and is movably mounted on the main body 110 so that the rotating unit 132 rotates by interaction with the rotating unit 132. It may include a locking portion 134 that maintains the fully locked state shown in Figure 5.

Here, the rotating part 132 is a support part 132A that supports rotation about the rotating axis. When the storage space is closed by the opening and closing part 120 due to an external force of the manager while the storage space is open, the storage space is opened. A contact portion 132B that allows the support portion 132A to rotate by contacting the protrusion 122 of the opening and closing portion 120, and is caught by the locking portion 134 so that the support portion 132A is tilted at a predetermined angle. A toothed portion 132C extending from the support portion 132A may be provided to maintain the rotated state, that is, the fully locked state shown in FIG. 5 .

The locking part 130 is a first elastic part that allows the support part 132A to automatically rotate by the restoring force caused by elastic deformation when the sawtooth part 132C is released from the locking part 134. (136) may be further included.

The first elastic part 136 is a type of coil spring that can be inserted into and fixed to the rotating shaft, and one side is fixed on the main body 110 and the other side is fixed on the rotating part 132, as shown in FIG. In the case of a fully locked state, it may be maintained in an elastically deformed state.

The first elastic part 136 may be a coil spring as described above, but it is not necessarily limited thereto, and any structure that can provide rotational force to the rotary part 132 can be applied.

Figures 6 and 7 are diagrams to explain the principle of opening the storage space by rotating the opening and closing part provided in the medicine storage cassette according to the present invention with respect to the main body.

As shown in FIG. 2, the manager who has been certified with access to medicines pulls out the second drawer 10-2 equipped with the medicine storage cassette 100 that needs to be discharged or replenished from the frame 20. can do.

When the second drawer 10-2 is pulled out from the frame 20, as shown in FIG. 3, the opening/closing part 120 of the medicine storage cassette 100 that needs to discharge or replenish medicine is connected to the locking part 130. The movement of the machine automatically rotates to open the storage space where the medicine is stored.

Referring to FIG. 6, the locking portion 130 includes a locking release portion 138 that allows the position of the locking portion 134 to be moved so that the toothed portion 132C is released from the locking portion 134. It can be included.

The latch release unit 138 is mounted on a drive unit 138A, which is a type of motor for providing rotational driving force, and a rotation axis of the drive unit 138A to change the rotational movement of the rotation axis to the reciprocating movement of the latch unit 134. It may include a cam portion (138B) for.

In other words, the latch release part 138 is a component that enables linear movement of the latch part 134 by rotation.

When the driving unit 138A is operated and the rotation shaft rotates half a turn, the cam part 138B is interlocked and rotates half a turn, and the rotation of the cam part 138B causes the locking part 134 to retreat and the toothed part The state in (132C) is released.

At this time, the rotating part 132, which was maintaining the fully locked state shown in FIG. 5, is automatically rotated by the restoring force of the first elastic part 136, and at this time, as shown in FIG. 7, the contact part 132B is The protrusion 122 of the opening and closing part 120 is pressed, causing the opening and closing part 120 to rotate, and eventually the storage space is opened.

Here, the rotation angle of the support part 132A may be defined by the limit defining part 112, and the limit defining part 112 allows the support part 132A to be automatically adjusted by the first elastic part 136. It may be a component provided to protrude on the main body 110 so that when the support part 132A is rotated, the support part 132A is contacted and the maximum rotation angle of the support part 132A is defined.

Meanwhile, when the opening and closing part 120 is rotated to open the storage space, the driving part 138A can be rotated half a turn again to return the cam part 138B to its original position, and at this time, the locking part 134 is 2 It may advance again due to the restoring force caused by the elastic deformation of the elastic part 139 (see FIG. 5) and enter the state shown in FIG. 7.

Figure 8 is a diagram for explaining the incomplete locking state of the medicine storage cassette according to the present invention.

As explained with reference to FIGS. 6 and 7, the manager opens the storage space by rotating the opening and closing unit 120, and when discharging or replenishing the medicine is completed, the manager rotates the opening and closing unit 120 to open the storage space shown in FIG. 5. After applying an external force to change the space into a completely closed state, the second drawer 10-2 can be hidden within the frame 20.

Here, the manager intended to hide the second drawer (10-2) after changing it to a fully locked state by applying an external force, but unintentionally, even if the size of the external force was insufficient, the medicine storage cassette according to the present invention ( 100) may maintain an incompletely locked state rather than returning to the open state.

That is, the locking unit 130 is in a fully locked state in which the storage space is completely closed based on the magnitude of the external force applied to the opening and closing unit 120 when the storage space is open, and in an incomplete locking state in which the storage space is incompletely closed. One of the states can be maintained selectively.

Referring to FIG. 8, the locking unit 130 maintains the incomplete locking state when an external force smaller than the size of the external force that maintains the fully locked state is applied to the opening and closing unit 120, thereby maintaining the second drawer (10- 2) is hidden in the frame 20 and then re-drawn, the opening and closing part 120 must be prevented from being caught in the first drawer 10-1 located above the second drawer 10-2. You can.

At this time, as shown in FIGS. 9A and 9B, the medicine storage cassette 100 includes an opening/closing sensor 141 on an internal circuit board 140, and the locking unit 130 is detected through the opening/closing sensor 141. Incomplete locking status can be detected. When an incomplete locking state is detected through the opening/closing unit sensor 141, a warning message can be displayed to the manager through the display 30 so that the locking unit 130 can be changed to a fully locked state.

The opening/closing sensor 141 may be implemented as a micro switch capable of detecting the locked state of the locking unit 130, and the circuit board 140 receives the detection result of the opening/closing sensor 141 to detect that it is not completely closed. It may include an LED 142 for display and a Hall sensor 143 that detects the position of the cam unit 138B that operates while bound to the drive unit 138A.

Here, when the opening and closing part 120 is rotated by an external force applied by the manager, the protrusion 122 presses the contact part 132B of the rotating part 132, which causes the support part 132A to rotate and the first elastic The portion 136 is elastically deformed.

When the storage space is closed by the opening and closing unit 120 due to the external force of the manager while the storage space is open, the rotating part 132 is formed between the contact part 132B and the protrusion ( 122) may further include an insertion space providing portion (132D) extending from the support portion (132A) to be provided in the insertion space (S) for insertion.

Meanwhile, the toothed portion 132C of the rotating unit 132 has a plurality of teeth so that a plurality of incomplete locking states can be implemented, and this can be determined based on the magnitude of the manager's external force.

As described above, the medicine storage cassette 100 according to the present invention is incompletely locked in a state in which the opening and closing unit 120 is rotated at a predetermined angle even when an external force smaller than the external force for completely closing the storage space is applied to the opening and closing unit 120. The state can be maintained, and as a result, interference of the opening and closing unit 120 with the first drawer (10-1), which may occur when the second drawer (10-2) is redrawn, is prevented and the opening and closing unit (120) is maintained. Damage can be prevented in advance.

In addition, by preventing damage to the opening/closing unit 120, a weakening accident that may occur due to replenishment or discharge of incorrect medicine can be prevented in advance.

To this end, the medicine storage device 1 may further include at least one hall sensor 11 attached to each drawer 10, and the hall sensor 11 is attached to the main body of the medicine storage device 1. It is possible to detect whether the drawer 10 is completely drawn out by sensing the provided magnetic material.

Referring to FIG. 12, the drawer 10-2 may each include a hall sensor 11 in at least one area including the rear end of the side, and the drawer 10-2 may be stored or not completely withdrawn. In this state, the separate magnetic material 12 and the Hall sensor 11 provided in the medicine storage device 1 are separated from each other, and when completely withdrawn from the drawer 10-2, the magnetic material 12 and the Hall sensor 11 are separated from each other. As they become close to each other, the Hall sensor 11 can detect magnetism by the Hall effect.

The second processor 60 determines that the drawer 10-2 is fully drawn when the magnetism is detected by the hall sensor 11-3, and in this state, when a specific input signal is recognized for a preset time A software response request signal may be transmitted to the first processor 50.

On the other hand, when the magnetism is not detected by the hall sensor 11-3, the second processor 60 determines that the drawer 10-2 is stored or not completely withdrawn, and in this state, a specific input signal Even if it is recognized for a preset time, the software response request signal may not be transmitted to the first processor 50.

Additionally, as shown in FIG. 12, a plurality of Hall sensors 11 (11-1, 11-2, and 11-3) may be provided in each area of the side of the drawer (10-2). In this case, the second processor 60 may determine to what extent the drawer 10-2 has been withdrawn according to the detection results of each hall sensor 11-1, 11-2, and 11-3. Depending on the degree of exposure, only the opening and closing portion 120 of the exposed medicine storage cassette 100 may be controlled to be opened.

In addition, the Hall sensor 11 is a means for detecting the degree of withdrawal of the drawer 10. Even if the Hall sensor 11 and the magnetic material 12 are not combined, the hall sensor 11 detects the degree of withdrawal of the drawer 10, such as an optical sensor. It can include any sensor that can detect.

Meanwhile, when the control software operates normally, a response signal corresponding to the response request signal is transmitted to the second processor 60, and when the second processor 60 receives the response signal, the medicine storage device 1 It continues to operate in normal mode.

At this time, if the control software operates abnormally due to reasons such as the control software is not running, an error occurs, the license is not confirmed, or a communication failure occurs, a response signal to the response request signal is not sent. Transmission to the second processor 60 may not be possible.

In this case, the second processor 60 enters the medicine storage device 1 into emergency mode and controls the openings 120 of all medicine storage cassettes 100 in the drawer 10 in the withdrawn state to be opened. You can.

When the medicine storage device 1 enters the emergency mode, the second processor 60 may record logs about entering the emergency mode and the drawers withdrawn in a buffer or transmit them to an external server.

When the openings 120 of all medicine storage cassettes 100 are opened, the manager can take out the necessary medicines from the medicine storage cassettes 100 whose openings 120 are open.

Meanwhile, when there are a plurality of fully drawn drawers 10, the second processor 60 does not enter the emergency mode by not transmitting a software response request signal even if a specific input signal is recognized for a preset time, or Enter the emergency mode, but control the opening and closing part 120 of the medicine storage cassette 100 in the uppermost drawer among the drawn drawers 10 to open, so that the medicine storage cassette 100 and the upper drawer 10 collisions can be prevented.

When entering the emergency mode, the second processor 60 can control the display 30 to display a message notifying that the emergency mode is being entered, and depending on the embodiment, the device attached to the front of the medicine storage device 1 The LED can also be controlled to perform a blinking operation.

Meanwhile, the second processor 60 may be implemented in plural numbers to individually control the opening of the opening and closing portion 120 of the medicine storage cassette 100 in each drawer 10. Accordingly, each drawer 10 may be separately provided with a second processor 60 for opening the opening/closing portion 120 of the medicine storage cassette 100 within the drawer 10.

Therefore, in order to open the opening and closing part 120 of the medicine storage cassette 100 in each drawer 10, a specific input signal is input for a preset time and a software response request signal is sent to the first processor 50. The transmitting operation must be performed individually.

However, according to another embodiment of the present invention, a single second processor 60 may be implemented to control the opening of the opening and closing portion 120 of the medicine storage cassette 100 in all drawers 10. This will be described in detail later with reference to FIG. 14.

Figure 13 is a flowchart for explaining the operation sequence of the medicine storage device according to an embodiment of the present invention.

First, with the manager placing his/her hand inside one of the handles (10-2) provided on each front of the drawer (10) of the medicine storage device (1), the proximity sensor (40-1) installed inside the handle is activated by the manager. It is determined whether the hand of is recognized for more than 10 seconds (S1305).

When the proximity sensor 40-1 recognizes the manager's hand for more than 10 seconds (S1305: Yes), it is determined whether the drawer 10-2 has been unlocked and whether it has been completely withdrawn (S1310). If it is determined that the drawer 10-2 is unlocked and completely drawn out (S1310: Yes), a response request signal is transmitted to the running software to check whether communication is possible (S1315).

It is determined whether a response signal to the response request signal has been received from the running software (S1320), and if the response signal is not received (S1320: No), the mode of the medicine storage device 1 is entered into the emergency mode (S1330) ).

When entering the emergency mode, the LED attached to the front of the medicine storage device (1) is controlled to blink rapidly at a cycle of 50 ms to notify the administrator that the emergency mode has been entered. Additionally, while in the emergency mode, the flashing operation is continuously repeated to inform the manager that the drawer 10-2 is in the emergency mode.

Additionally, depending on the embodiment, a message notifying that the emergency mode is to be entered may be displayed on the display 30.

When the medicine storage device 1 enters the emergency mode, the openings 120 of all medicine storage cassettes 100 in the drawer 10 in a fully drawn state are opened (S1335).

In the case of the above-described embodiment in which the plurality of second processors 60 individually control the opening of the cover of the medicine storage cassette 100 in each drawer 10, the operations of steps S1305 to S1330 described above are performed in the drawer ( 10) It must be performed repeatedly.

However, in the case of an embodiment in which a single second processor 60 controls the opening of the opening and closing portion 120 of the medicine storage cassette 100 in all drawers 10, the operations of steps S1305 to S1330 are performed in the drawer 10. As shown in FIG. 14, as shown in FIG. 14, as long as each drawer 10 is completely withdrawn (S1320: Yes) in the emergency mode, the cover of the medicine storage cassette 100 is opened. It can be opened (S1310).

For example, after the medicine storage cassette 100 of the first drawer 10-1 is taken out, the first drawer 10-1 from which the medicine was taken out is stored again, and the second drawer 10 When -2) is completely drawn, the second processor 60 may control the opening/closing portion 120 of the medicine storage cassette 100 to be opened without determining whether a specific input signal has been recognized for a preset time.

Accordingly, if the manager needs to take out medicine from a plurality of drawers 10 in emergency mode, once the emergency mode is entered, the operations of steps S1305 to S1330 do not need to be repeated for each drawer 10. .

On the other hand, if the proximity sensor (40-1) does not recognize the administrator's hand for more than 10 seconds (S1305: No) because the administrator quickly removes his/her hand, the drawer (10) is not unlocked or even if it is unlocked. If complete withdrawal is not made (S1310: No) or if a response signal according to the response request signal is received from the software (S1320: Yes), the medicine storage device 1 can maintain the environment before entering the emergency mode (S1325) . In addition, when entering the emergency mode, if a command to release the emergency mode is received from the software (S1340: Yes), the medicine storage device 1 is converted to the normal mode (S1345).

Figure 15 is a flowchart briefly explaining a control method for opening the opening and closing portion of a medicine storage device in case of emergency according to an embodiment of the present invention.

First, a specific input signal is detected by one of the emergency mode entry units provided on the front of the drawer (S1510).

Thereafter, when a specific input signal is detected to be in proximity for a preset time, a response request signal from the second processor for software to control the opening and closing portions of a plurality of medicine storage cassettes inserted and fixed into the drawer inner space of the medicine storage device in normal mode. is transmitted to the first processor (S1520).

At this time, the emergency mode entry unit may include a proximity sensor attached to the inside of the handle of the drawer, and when the manager's hand is recognized as being close to the proximity sensor for more than a preset time, a response request signal from the software may be transmitted to the first processor. there is.

In addition, it is determined whether the drawer is fully withdrawn based on the sensing result of the magnetic material provided in the main body of the medicine storage device by at least one hall sensor attached to the drawer, and a specific input signal is output when the drawer is fully withdrawn. A response request signal from the software can be transmitted to the first processor only when it is recognized during a preset time.

Afterwards, if a response signal to the response request signal is not received within a preset time, the emergency mode is entered (S1530).

Thereafter, with the drawer fully withdrawn, the openings and closing portions 120 of all medicine storage cassettes within the withdrawn drawer are opened (S1540).

In addition, when entering the emergency mode, if there are a plurality of drawers drawn out, only the openings and closing parts of all medicine storage cassettes in the uppermost drawer among the drawn drawers can be opened.

Meanwhile, when entering the emergency mode, a message notifying that the emergency mode is being entered can be displayed on the display, or the LED attached to the front of the medicine storage device can be made to blink. Additionally, the LED may continuously blink while in emergency mode.

In addition, when an emergency mode release command is received from the control software after all openings and closing parts of a plurality of medicine storage cassettes are opened in the emergency mode, the device can be switched to the normal mode.
