[0026] The present invention will now be described in conjunction with the accompanying drawings. The specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Various modifications and improvements to the technical solutions of the present invention made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope of the present invention.

[0027] like Figures 1 to 12 As shown, the psychiatric nursing dressing change cart of this embodiment includes a box 1, rollers 2, drawer 3, partition 4, radio frequency identification card 5, and locking device 6.

[0028] The box body 1 is a hollow square structure with an opening on its front surface. Multiple partitions 4 are spaced along the height of the box body 1 within the opening. The gaps between the partitions 4 are used to place drawers 3. The gaps between the top partition 4 and the upper wall of the box body 1 opening, and between the bottom partition 4 and the bottom wall of the box body 1, are also used to place drawers 3. The sides of the drawers 3 are slidably connected to the inner walls on both sides of the box body 1 opening. Multiple casters 2 with brakes are located at the bottom of the box body 1. An operating platform is located on the upper surface of the box body 1, and push rods and hanging slots are located on the upper side walls of the box body 1.

[0029] Each drawer 3 is equipped with a locking device 6. In this embodiment, the locking device 6 includes a housing 61, a card reader 62, a central processing unit 63, a storage module 64, a pressure sensor 65, a locking mechanism 66, and a power module 67. The housing 61 is located on the front surface of the drawer 3 (the surface of the drawer 3 at the opening of the box 1). The card reader 62, central processing unit 63, storage module 64, and power module 67 are located inside the housing 61. The card reader 62 is electrically connected to the central processing unit 63 and is used to read the card number of the RFID card 5 and send the read information to the central processing unit 63. The storage module 64 is electrically connected to the central processing unit 63 and is used to store authorized card number information. The pressure sensor 65 is located on the rear surface and is electrically connected to the central processing unit 63. The locking mechanism 66 is disposed between the drawer 3 and the partition 4 above the drawer 3. It is electrically connected to the central processing unit 63. The central processing unit 63 is used to control the operation of the locking mechanism 66 and to connect the drawer 3 and the partition 4 and disconnect the connection between the drawer 3 and the partition 4. The power module 67 is used to provide the working voltage.

[0030] In this embodiment, the card reader 62 includes an MFRC522 RFID module and an inductor L2. The MFRC522 RFID module is electrically connected to the central processing unit 63 and the inductor L2, respectively. The RFID card 5 is held in the hand of a medical staff member and includes a card body, an ID chip disposed in the card body, an LC resonant circuit composed of inductor L1 and capacitor C1, a rectifier bridge circuit, and a Zener diode. The MFRC522 RFID module of the card reader 62 continuously emits electromagnetic waves of a specific frequency (such as 13.56MHz) into its surroundings through the inductor coil L2. When the RFID card 5 is close to the card reader 62, that is, when it enters the electromagnetic field range, the LC resonant circuit inside the card body will resonate due to the principle of electromagnetic induction, thereby generating a weak induced current. This current is rectified by the rectifier bridge circuit and regulated by the Zener diode circuit, and then provides a power supply voltage to the ID chip. After the ID chip is "activated", it will "reflect" or send the unique identifier (card number) stored inside it back to the card reader 62 through the electromagnetic waves via the inductor coil L1. The MFRC522 RFID module receives the electromagnetic wave signal reflected back by the RFID card 5, demodulates and decodes the signal, and converts it into a digital signal (i.e., card number) that the central processing unit 63 can understand.

[0031] In this embodiment, the central processing unit 63 uses a microcontroller module with an STM32F103C8T6 microcontroller as its core. The storage module 64 includes a 24C02 memory chip, which stores authorized card number information. After receiving the card number information identified by the card reader 62, the central processing unit 63 compares it with the authorized card number information in the storage module 64 to determine whether the RFID card 5 is authorized. Each locking device 6's storage module 64 stores the authorization information of the RFID card 5, enabling one card to control multiple locking devices 6. Furthermore, a sensing area 611 is provided on the front surface of the housing 61, and the card reader 62 is positioned below the sensing area 611. When the RFID card 5 is placed in the sensing area 611, the card reader 62 can read the information.

[0032] The locking mechanism 66 of this embodiment includes an electric push rod 661 and a plug rod 662. Each drawer 3 has a receiving groove 31 at its front end. The electric push rod 661 and the plug rod 662 are disposed in the receiving groove 31. The fixed end of the electric push rod 661 is fixed in the receiving groove 31, and its telescopic end is connected to the lower end of the plug rod 662. The electric push rod 661 is electrically connected to the central processing unit 63. The upper surface of the front end of the drawer 3 is provided with a through hole 32 for the upper end of the plug rod 662 to extend out, and the through hole 32 communicates with the receiving groove 31. The lower surface of the partition 4 above the drawer 3 is provided with a slot 41 facing the through hole 32. The telescopic end of the electric push rod 661 pushes the upper end of the plug rod 662 into the slot 41 or pulls the upper end of the plug rod 662 out of the slot 41. When the upper end of the plug rod 662 is inserted into the slot 41, part of its rod body is located in the through hole 32. At this time, the drawer 3 is blocked by the plug rod 662, which can prevent the drawer 3 from being pulled out. When the upper end of the plug rod 662 is out of the slot 41, its rod body is located in the receiving groove 31 and the through hole 32, the drawer 3 is released, and the drawer 3 can be pulled out. To improve stability, a baffle 663 is provided between the telescopic end of the electric push rod 661 and the insert rod 662. Three insert rods 662 are mounted on the baffle 663. Correspondingly, three through holes 32 and three slots 41 are provided. The partition 4 is positioned below the through hole 32. The blocking effect of three insert rods 662 is better than that of a single insert rod 662. If it is the top drawer 3, then its corresponding slot 41 is located on the upper wall of the cabinet 1.

[0033] In this embodiment, the electric push rod 661 is represented by M in the circuit. When the drawer 3 is pushed into the cabinet 1, the pressure sensor 65 contacts the inner wall of the cabinet 1 (the side wall directly opposite the opening of the cabinet 1). At this time, the through hole 32 corresponds vertically to the slot 41, and the pressure sensor 65 generates a pressure signal. The pressure sensor 65 sends the pressure signal to the central processing unit 63. After receiving the pressure signal, the output terminal (PB1 pin) of the central processing unit 63 outputs a high level to the base of transistor Q1 and a low level to the base of transistor Q2, making transistor Q1 conduct and transistor Q2 deconduct. Subsequently, the coil of relay KA1 is energized, and the normally open terminal of relay KA1 closes. The coil of relay KA2 is de-energized, and the normally closed terminal of relay KA2 closes. At this time, the electric push rod 661 is forward-biased, and its telescopic end is extended to push the insertion rod 662 into the slot 41, achieving automatic locking. After the RFID card 5 is successfully recognized by the central processing unit 63, the output terminal (PB1 pin) of the central processing unit 63 outputs a low level to the base of transistor Q1 and a high level to the base of transistor Q2, making transistor Q1 non-conducting and transistor Q2 conducting. Consequently, the coil of relay KA1 is de-energized, the normally closed terminal of relay KA1 is closed, the coil of relay KA2 is energized, and the normally open terminal of relay KA2 is closed. At this time, the electric push rod 661 conducts in reverse, and its telescopic end is shortened to pull the insertion rod 662 out of the slot 41, achieving unlocking.

[0034] In addition, a groove 612 is provided on the front surface of the outer casing 61. A reset button 68, electrically connected to the central processing unit 63, is provided on the bottom wall of the groove 612. In the circuit, it is represented by button K1. After pressing the reset button 68, the output terminal (PB1 pin) of the central processing unit 63 outputs a low level to the base of transistor Q1 and a high level to the base of transistor Q2, respectively, to unlock the locking device. The purpose of setting the reset button 68 is to prevent the locking device 6 from being unable to be opened after the RFID card 5 is lost. A protective cover 7 is provided above the reset button 68. One end of the protective cover 7 is hinged to the two side walls of the groove 612, and the other end is connected to the bottom wall of the groove 612 by bolts 71. By unscrewing the bolts 71 with a tool, the protective cover 7 can be opened to expose the reset button 68.

[0035] On the front surface of the housing 61 are a signal indicator light 8 and a speaker 9, both electrically connected to the central processing unit 63. There are two signal indicator lights 8, a green light and a red light, denoted as D5 and D6 in the circuit. When the pressure sensor 65 detects pressure, it indicates a locked state; in this case, the central processing unit 63 controls the green light to illuminate while the red light remains off. When the pressure sensor 65 does not detect pressure, it indicates an unlocked state; in this case, the central processing unit 63 controls the red light to illuminate while the green light remains off. The speaker 9, denoted as SPEEKER in the circuit, emits a sound after the RFID card 5 is successfully recognized by the central processing unit 63, indicating successful unlocking. Generally, the microcontroller has a timing function. If the drawer 3 is not pulled out within 60 seconds (or 30 seconds) after unlocking, meaning the pressure sensor 65 continues to detect pressure, the central processing unit 63 will control the locking device 6 to lock after one minute of timing.

[0036] The power module 67 in this embodiment includes a charging circuit, a battery (represented by J1 in the circuit diagram), a 5V power supply circuit, a 3.3V power supply circuit, and a 12V power supply circuit. The charging circuit includes a USB charging port 10 and a TC4056A charging chip located on the side wall of the housing 61. After connecting a charger, the battery J1 is charged through the TC4056A charging chip. The 5V power supply circuit includes a KF2185 chip, used to regulate the output voltage of the battery to a 5V DC voltage. The 3.3V power supply circuit includes an ME6211C33M5G chip, used to step down the 5V voltage to a 3.3V DC voltage. The 12V power supply circuit includes an MC34063 chip, used to boost the 5V voltage to a 12V DC voltage. Multiple power supply circuits work together to meet the power supply needs of different components. When the indicator light 8 fails to illuminate, it indicates that the battery is depleted and needs to be charged.

[0037] In summary, the psychiatric nursing dressing change trolley provided by this utility model has the advantage of high safety because each drawer 3 is equipped with a locking device 6. When medical staff change the patient's dressing, the locking device connects the drawer 3 and the partition 4 above the drawer 3, preventing the drawer 3 from being opened. This prevents the patient from opening the drawer 3 to take the medication, and the trolley has the advantage of high safety. When it is necessary to open the drawer 3, the medical staff attaches the RFID card 5 to the sensing area 611. The card reader 62 reads the card number of the RFID card 5 and sends the card number information to the central processing unit 63. The central processing unit 63 compares the received card number information with the authorized card number information stored in the storage module 64. If the comparison is correct, the card number is automatically generated. The extension end of the electric push rod 661 of the locking device 6 shortens, causing the insert rod 662 to disengage from the slot 41, thus separating the drawer 3 from the partition 4, allowing the drawer 3 to be pulled out, which has the advantage of convenient operation. When the drawer 3 is pushed in again, after the rear end face of the drawer 3 contacts the inner wall of the cabinet 1, the pressure sensor 65 generates a pressure signal and sends the pressure signal to the central processing unit 63. After receiving the pressure signal, the central processing unit 63 controls the extension end of the electric push rod 661 of the locking device 6 to extend, so that the upper end of the insert rod 662 is inserted into the slot 41, connecting the drawer 3 and the partition 4 together, thus locking the drawer 3 again and preventing it from being opened.
