[0018] In the medical field, the storage and management of special drugs is a crucial task, which is directly related to the treatment effect and life safety of patients. These special drugs often have extremely strict requirements on storage environment conditions such as temperature and humidity. Any slight deviation may affect the stability and effectiveness of the drugs, thereby leading to reduced efficacy or even deterioration, thus causing serious medical consequences.

[0019] However, traditional drug storage methods mostly rely on manual operations and simple physical facilities, lack intelligent management methods, and are difficult to achieve accurate counting and real-time status monitoring of drug inventory. This not only increases the risk of drug expiration, misuse or loss, but also poses challenges to the effective allocation of medical resources. Traditional drug storage drawers require manual operation. During the opening and closing process, medical staff may forget to completely close the drawer due to busyness or negligence, which will not only cause the drugs to be exposed to inappropriate environments, but may also cause a series of safety issues.

[0020] Therefore, smart medicine cabinets with automatic opening and closing drawers through electric drive have appeared on the market, but these products are not perfect. They are prone to being unable to open and close the drawers due to various faults. Especially in emergency situations, if the drawers cannot respond quickly and open in time, it will affect the medical staff's medication and delay precious treatment time, which will cause great trouble to medical treatment.

[0021] Based on this, in order to improve the technical problem in the related art that the electric drive drawers of the smart medicine cabinet are prone to failure to open and close normally to access medicines, the embodiments of the present application provide the following solution.

[0022] The following combination Figure 1 - Figure 6 The present invention is described in further detail.

[0023] Embodiment 1: The present embodiment provides an electric switch anti-pinch medicine storage drawer, comprising a drawer tray 1, a drawer body 2, a drive assembly 3 and a buckle assembly 4. The drawer tray 1 is fixed in the medicine storage cabinet body, and the drawer body 2 and the drive assembly 3 are both arranged on the drawer tray 1. Two sets of drawer slide rails 101 are symmetrically fixedly installed on both sides of the drawer tray 1, and slide bars 206 are symmetrically fixedly connected on both sides of the drawer body 2, and the slide bars 206 are slidably inserted on the drawer slide rails 101. The drawer body 2 can achieve smooth sliding through the slide bars 206 and the drawer slide rails 101. The drawer body 2 is driven by the drive assembly 3 to achieve automatic opening and closing, which is easy to operate and is conducive to improving the efficiency of medicine storage and retrieval. The medicine storage method of this embodiment adopts a modular design. When the drawer body 2 or the drive assembly 3 fails, the connection between the drawer body 2 and the drive assembly 3 can be released by the buckle assembly 4, and it can be easily assembled and disassembled with the main structure of the smart cabinet, which is convenient for maintenance and upgrading.

[0024] Four medicine storage boxes 201 are arranged in the drawer body 2. A weighing sensor is installed at the bottom of each medicine storage box 201, which can monitor and count the weight of the medicines placed in the box in real time, thereby improving the accuracy of medicine management. A liquid crystal display screen 202 is arranged at the junction of the four medicine storage boxes 201, which can intuitively display the storage information of the medicines in each medicine storage box 201, including the name, quantity, weight, etc. of the medicines, so that the management personnel can quickly understand the status of the medicines. A corresponding RGB three-color indicator light is arranged at the position corresponding to each medicine storage box 201 on the liquid crystal display screen 202. Different light colors will be displayed in real time when taking more or less medicines when storing or retrieving medicines, thereby giving the user a more intuitive prompt. A wire trough drag chain 102 is fixedly installed on the drawer tray 1, and the end of the wire trough drag chain 102 is fixedly connected to the drawer body 2, and a control panel 104 is arranged on one side of the wire trough drag chain 102.

[0025] Such a setting can realize intelligent management of drugs, which is conducive to accurate counting and effective monitoring of drugs, as well as helping to improve the efficiency of drug storage and retrieval, reduce manual operation costs, intuitively display drug information, and facilitate managers to quickly query and make decisions to replenish or take drugs.

[0026] In some embodiments, please refer to Figure 1 - Figure 3As shown, the driving assembly 3 includes a stepper motor 301 and a fixing frame 302 fixedly mounted on the drawer tray 1, and the stepper motor 301 is arranged on one side of the fixing frame 302, and a screw rod 303 is rotatably mounted on the fixing frame 302, and the rotating screw rod 303 can control the push plate 305 to make reciprocating linear motion along the screw rod 303, and an electromagnetic coupling 306 is fixedly mounted on the end of the screw rod 303, and the electromagnetic coupling 306 is coaxially connected to the output end of the stepper motor 301, and the stepper motor 301 can control the rotation of the screw rod 303 through the electromagnetic coupling 306. When the stepper motor 301 is powered off, the electromagnetic coupling 306 is disconnected from the stepper motor 301 due to the loss of electromagnetism, and can then rotate independently.

[0027] The push plate 305 is rotatably inserted on the screw rod 303. The push plate 305 is controlled by the screw rod 303 to push the drawer body 2 to realize the automatic opening and closing action of the drawer body 2. Two groups of limit rods 304 are slidably inserted on the push plate 305, and the two groups of limit rods 304 are respectively located on both sides of the screw rod 303. Both ends of the limit rod 304 are fixedly connected to the fixed frame 302. The limit rod 304 limits the movement of the push plate 305 to prevent the push plate 305 from rotating with the rotation of the screw rod 303.

[0028] With such arrangement, when it is normally necessary to take medicine or replenish medicine from the drawer body 2, the stepper motor 301 is started by a control signal, and the stepper motor 301 controls the rotation of the screw rod 303 through the electromagnetic coupling 306, and the push plate 305 moves with the rotation of the screw rod 303, and the push plate 305 pushes the drawer body 2 out of the drawer tray 1; when the stepper motor 301 is powered off and it is necessary to take medicine, at this time, the electromagnetic coupling 306 is disconnected from the stepper motor 301, and the drawer body 2 can be directly pulled out, the push plate 305 can move directly with the drawer body 2, and the screw rod 303 can drive the electromagnetic coupling 306 to rotate together. It should be noted that the screw rod 303 in the embodiment of the present application has a larger pitch setting, which is beneficial to improving the transmission efficiency and facilitating the rapid movement of the drawer body 2, and when the stepper motor 301 is powered off and the screw rod 303 rotates, it is beneficial to reduce the wear of the push plate 305 on the screw rod 303, which is beneficial to extending the service life of the screw rod 303.

[0029] The implementation principle of an electric switch anti-pinch medicine storage drawer in Example 1 of the present application is as follows: the medicine storage method adopts a modular design, and efficient and safe management of special drugs is achieved through intelligent management means. The intelligent weighing and counting function improves the accuracy and transparency of medicine management. The LCD display 202 intuitively displays medicine information, which is convenient for managers to make quick decisions. When it is normally necessary to take medicine or replenish medicine from the drawer body 2, the stepper motor 301 is started by a control signal, and the stepper motor 301 controls the rotation of the screw rod 303 through the electromagnetic coupling 306. The push plate 305 moves with the rotation of the screw rod 303, and the push plate 305 pushes the drawer body 2 to move, thereby realizing the electric drive control of the opening and closing of the drawer body 2; when a power outage occurs in the smart medicine cabinet, the electromagnetic coupling 306 is disconnected from the stepper motor 301, and the drawer body 2 can be directly pulled out, avoiding the problem that the drawer body 2 cannot be pulled out.

[0030] Embodiment 2: The present application also provides a method for quickly pulling out the drawer body 2 when the drawer tray 1 fails. In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6 The driving assembly 3 also includes a push plate 305, on which two groups of limit blocks 3051 are fixedly installed, and a first inverted inclined surface is provided on the side close to the connecting plate 401. The buckle assembly 4 includes a connecting plate 401 fixedly installed on the outside of the drawer body 2, on which a fixed shaft seat 402 is fixedly installed, and a flap 403 is rotatably sleeved on the fixed shaft seat 402, and a buckle 404 is fixedly installed on one side of the flap 403, and a torsion spring 405 is provided on the fixed shaft seat 402, and the two ends of the torsion spring 405 are respectively fixedly connected to the connecting plate 401 and the flap 403.

[0031] The latch 404 is provided with a second inverted slope. After the latch 404 is buckled on the limit block 3051, the drawer body 2 and the drive assembly 3 are connected. The drive assembly 3 is used to control the reciprocating movement of the drawer body 2 by driving the push plate 305. When the latch 404 is separated from the limit block 3051 and the drawer body 2 and the drive assembly 3 need to be reconnected, the push plate 305 is pushed toward the drive assembly 3, and the first inverted slope of the limit block 3051 can fit the second inverted slope of the latch 404 to move. , and lifts up the latch 404 to squeeze the torsion spring 405, so that the latch 404 rotates along the axis of the fixed shaft seat 402. When the first inverted slope of the limit block 3051 is completely misaligned with the second inverted slope of the latch 404, the latch 404 loses the thrust of the limit block 3051, and the torsion spring 405 is elastically released, reacting on the latch 404, pushing the latch 404 back to reset, so that the latch 404 is re-locked onto the limit block 3051, completing the connection between the drawer body 2 and the drive assembly 3.

[0032] With such an arrangement, in an emergency situation where there is no power outage but other equipment failures occur, if medicines are urgently needed, the person taking the medicines can go to the back of the cabinet, flip up the flip plate 403, rotate the fastener 404, separate the fastener 404 and the limit block 3051, and then manually pull out the drawer body 2 from the drawer tray 1, ensuring the flexibility and reliability of medicine retrieval. After solving the failure problem, it is only necessary to push the drawer body 2 deeper into the drawer tray 1 to complete the connection between the drawer body 2 and the drive assembly 3, thereby achieving quick installation and easy operation.

[0033] The implementation principle of an electric switch anti-pinch medicine drawer in Example 2 of the present application is: when the smart medicine cabinet fails and medicines are urgently needed, the connection between the drawer body 2 and the drive assembly 3 can be quickly released by separating the fastener 404 and the limit block 3051, so that the drawer body 2 can be manually pulled out from the drawer tray 1 to take medicines. Different from the manual drawer extraction method in Example 1, in this Example 2, the drawer pulling speed is faster than that in Example 1 in an emergency situation, and no damage is caused to the drive assembly 3. After the drawer body 2 is completely pushed back into the cabinet 1, the quick installation is completed.

[0034] Embodiment 3: The present application also provides a device for preventing fingers from being pinched by an electric switch anti-pinch medicine drawer. In some embodiments, please refer to Figure 1-Figure 4 As shown, a closing button 205 is fixedly installed above the door panel of the drawer body 2, and the closing button (205) is electrically connected to the stepper motor (301). After the operation of storing and retrieving medicines is completed, the closing button 205 can be pressed to transmit a control signal to the stepper motor 301, and the stepper motor 301 is started to control the push plate 305 to retract the drawer body 2 through the screw rod 303, thereby realizing the automatic closing of the drawer body 2. Since the drawer body 2 is automatically closed, the user may be caught in the process of closing the drawer body 2 due to negligence and failure to withdraw the hand from the drawer body 2 in time, so an anti-pinch assembly 203 is provided on the inner side of the door panel of the drawer body 2.

[0035] The anti-pinch assembly 203 includes a fixed plate 2031, a baffle 2032 is arranged on one side of the fixed plate 2031, and multiple groups of springs are arranged between the fixed plate 2031 and the baffle 2032. The springs can ensure that a certain distance is always maintained between the fixed plate 2031 and the baffle 2032 when there is no external force pushing the baffle 2032. Two groups of positioning rods 2033 are slidably inserted on the baffle 2032. The user can press the baffle 2032 to slide on the positioning rods 2033. The end of the positioning rod 2033 is provided with a thread. The positioning rod 2033 passes through the fixed plate 2031 and a nut is provided on the threaded sleeve. The positioning rod 2033 limits the displacement range of the baffle 2032 and is easy to disassemble, repair and replace.

[0036] A plurality of signal sensors 2035 are fixedly installed on the side of the fixed plate 2031 away from the baffle 2032, and the signal sensors 2035 are electrically connected to the stepper motor 301. A plurality of positioning blocks 2034 are fixedly connected to the side of the fixed plate 2031 close to the signal sensors 2035, and the positions of the positioning blocks 2034 correspond one-to-one to the signal sensors 2035. When the user pushes the positioning blocks 2034 on the baffle 2032 to contact the signal sensors 2035 due to pinching of the hands, the signal sensor 2035 immediately transmits a control signal to the stepper motor 301, so that the stepper motor 301 is powered off and stops the rotation of the screw rod 303.

[0037] Two groups of positioning sensors 103 are fixedly installed on the drawer tray 1 at both ends relative to the screw rod 303. When the positioning sensor 103 detects the positioning piece 204 of the drawer body 2, the drawer body 2 moves into place, and its state is either fully expanded or fully closed. A positioning piece 204 is fixedly installed on one side of the drawer body 2, and the positioning piece 204 is on the same side as the buckle assembly 4. The positioning sensor 103 monitors whether the drawer body 2 moves into place through the positioning piece 204 to avoid the problem of drug leakage due to incomplete recovery of the drawer body 2 when the drawer body 2 is folded. The positioning sensor 103 is connected to the stepper motor 301 by electrical signals. When the positioning sensor 103 detects that the drawer body 2 moves into place, the positioning sensor 103 transmits a stop signal to the stepper motor 301.

[0038] The implementation principle of an electric switch anti-pinch medicine storage drawer in Example 3 of the present application is: the closing button 205 transmits a control signal to start the stepper motor 301 to control the push plate 305 to retract the drawer body 2 through the screw rod 303, thereby realizing the automatic closing of the drawer body 2. When the user triggers the anti-pinch hand component 203 because he fails to withdraw his hand from the drawer body 2 in time, the hand will squeeze the baffle 2032 due to being pinched, and the baffle 2032 slides on the positioning rod 2033, pushing the positioning block 2034 on the baffle 2032 to contact the signal sensor 2035. The signal sensor 2035 immediately transmits a control signal to the stepper motor 301, so that the stepper motor 301 is powered off and the rotation of the screw rod 303 is stopped, thereby avoiding the push plate 305 pulling the drawer body 2 to further clamp the user's hand and cause damage.

[0039] The working process of an electric switch anti-pinch medicine storage drawer in this application is as follows: S1: The user starts the stepper motor 301 through the control system, and the stepper motor 301 controls the screw rod 303 to rotate through the electromagnetic coupling 306. The push plate 305 moves with the rotation of the screw rod 303, and the push plate 305 pushes the drawer body 2 out; S2; the user can directly take medicine from the medicine box 201, or can quickly understand the storage information of each medicine box 201 through the LCD screen 202, so as to determine whether it is necessary to prepare to replenish the medicine in the medicine box 201; S3: When the drawer is ready to be closed, only the closing button 205 needs to be pressed, and the closing button 205 transmits a control signal to start the stepping motor 301 to control the push plate 305 to withdraw the drawer body 2 through the screw rod 303, thereby realizing the automatic closing of the drawer body 2; S4: When encountering the drawer body 2, the hand-pinch prevention component 203 will be triggered, and the hand will be squeezed by the baffle 2032 due to being pinched. The baffle 2032 slides on the positioning rod 2033, pushing the positioning block 2034 on the baffle 2032 to contact the signal sensor 2035. The signal sensor 2035 immediately transmits a control signal to the stepper motor 301 to cut off the power of the stepper motor 301, stop the rotation of the screw rod 303, and disconnect the electromagnetic coupling 306 from the stepper motor 301. The user can pull the drawer body 2 outward to relieve the further clamping damage of the drawer body 2 to the user's hand. S5: When the smart medicine cabinet fails and medicines need to be taken urgently, the user can go to the back of the cabinet, lift up the flip plate 403, rotate the latch 404, separate the latch 404 and the limit block 3051, and then manually pull out the drawer body 2 from the drawer tray 1, ensuring the flexibility and reliability of medicine retrieval. After solving the fault problem, the user only needs to push the drawer body 2 deeper into the drawer tray 1 to complete the connection between the drawer body 2 and the drive assembly 3.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
