[0001] This invention relates to the field of medical supply cabinet technology, and specifically discloses a medical device cabinet. Background Technology
[0002] In hospital operating rooms, emergency centers, and other similar settings, the management of medical devices demands extremely high standards, requiring efficient storage and retrieval, rigorous disinfection, accurate traceability, and emergency preparedness. Traditional instrument cabinets are often simple storage units, relying on separate disinfection equipment for sterilization and manual retrieval and handling. This results in inefficiency, error-proneness, a disconnect between disinfection and storage, and an inability to handle emergencies. Some automated equipment attempts have attempted improvements, such as using rotating conveyors or robotic arms, but these often suffer from complex structures, questionable reliability, inconsistent disinfection effectiveness, and a lack of emergency access channels in case of power outages or malfunctions, failing to meet the high reliability and safety requirements of medical settings. Therefore, there is an urgent need for an intelligent medical device management device that deeply integrates storage, intelligent scheduling, independent and sealed disinfection, personnel operation traceability, and rapid emergency response functions, while also possessing a stable structure and clear processes.

[0018] 2. Process optimization and efficiency improvement: The system adopts a model of "static matrix storage + dynamic truss handling + independent compartment disinfection". The storage chamber is responsible for efficient warehousing and scheduling, while the disinfection chamber is dedicated to deep disinfection. The two can work in parallel, and standardized delivery through the ingredient storage compartment greatly shortens the preoperative preparation time.
[0019] 3. Thorough disinfection, safe and reliable: The disinfection chamber is an independent and sealed space that can integrate multiple disinfection methods (such as UVC, hydrogen peroxide, etc.). The disinfection parameters are controllable, the process is monitorable, and the effect is verifiable, which is far superior to open irradiation disinfection.
[0020] 4. The independent emergency chamber and physical ejection structure ensure that emergency medical equipment can be accessed within seconds via the emergency button or manual operation in any situation (including power failure or malfunction of the main system), meeting the ultimate reliability requirements of medical scenarios.
[0021] 5. Intelligent verification to eliminate errors: Through the weighing sensors and scanning light curtain in the batching hopper, automatic integrity verification is carried out before the equipment is delivered, which technically eliminates the possibility of equipment being missed or misplaced.
[0022] 6. Full traceability and clear responsibility: The combination of card swiping authentication, wide-angle camera recording, and operation logs enables full traceability of "people, time, events, and things," meeting the requirements of medical quality management and auditing.
[0023] 7. Clear modules and convenient maintenance: Each functional module (storage, disinfection, emergency response, and delivery) is relatively independent, with a clear structure, which facilitates fault diagnosis and component maintenance. Attached Figure Description

Detailed Implementation
[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0029] refer to Figures 1 to 3 .
[0030] This invention provides a medical device cabinet, mainly comprising a cabinet body 10. An intelligent control system 43 is installed on the top of the cabinet body 10 to coordinate and control all automated components within the cabinet. A first sealing door 16 is installed on the front of the cabinet body 10, integrating a touch screen 13 and a card reader 12. The interior of the cabinet body 10 is divided into three independent chambers by vertical sealing partitions: a sterilization chamber 19 on the left, a storage chamber 44 in the middle, and an emergency chamber 18 on the right. The passage between the sterilization chamber 19 and the storage chamber 44 is controlled by a first pneumatic sealing door 20 to achieve strict airtight isolation. There is no direct communication passage between the storage chamber 44 and the emergency chamber 18.
[0031] A drawer storage cabinet 17 is fixedly installed inside the storage cavity 44. Multiple drawer storage compartments are arranged in a matrix on its front (facing the first sealing door 16). Each storage compartment contains an independent drawer 21. The drawer 21 has a handle 22 and an LED indicator 23 on its panel and is locked to the cabinet body by an electromagnetic lock (not shown in the figure). A first material-grabbing assembly 29 is installed on the top of the storage cavity 44 for grabbing and transporting the designated drawer 21 according to instructions.
[0032] An emergency kit ejection mechanism 45 is installed inside the emergency compartment 18. This mechanism includes a sliding emergency kit storage compartment 27 and an electric push rod A28 that drives its movement. A second sealing door 15 and an emergency button 14 are installed at corresponding positions on the cabinet 10. Pressing the emergency button 14 opens the second sealing door 15, and the electric push rod A28 quickly ejects the emergency kit storage compartment 27, which contains a pre-installed first-aid kit, for direct access by medical personnel.
[0033] The disinfection chamber 19 is one of its core functional areas. Inside, there is an independent, sealable disinfection compartment 39 (which can house a UVC lamp array, plasma generator, etc.). Below the disinfection compartment 39 is a feeding structure 42, including an electric push rod B40 and a push plate 38. A second material handling assembly 41 is installed on the side of the disinfection chamber 19 away from the feeding structure 42 (near the storage chamber 44). A channel is opened on the side wall of the disinfection chamber 19, connecting to the external mixing compartment 11. This channel contains a conveying channel 33, with a lifting and sealing door 32 at its port. The mixing compartment 11 has a third sealing door (not shown in the figure) on its outer side. A high-precision weighing sensor 30 is installed on its bottom tray, and a high-resolution linear array scanning light curtain 31 is installed on its inner upper side. A wide-angle camera 36 is also installed above the mixing compartment 11.
[0034] The first picking assembly 29 and the second picking assembly 41 have the same structure, both being three-degree-of-freedom gantry robots. They include an X-axis slide 34 fixed to the top of the cabinet, a Y-axis slide 24 mounted on the X-axis slide, a telescopic drive motor 26 mounted on the Y-axis slide, a rotary drive motor 25 connected to the output of the telescopic drive motor 26, and a finger cylinder 35 mounted on the output of the rotary drive motor 25. The finger cylinder 35 is used to grip a special structure on the drawer 21.
[0035] The workflow of this invention is as follows:
[0036] 1. Standard inventory preparation process:
[0037] a. After the operator swipes their card for verification, they select a surgical package on touchscreen 13.
[0038] b. The intelligent control system 43 interprets the instructions and controls the first material handling component 29 to move to the corresponding position in the storage cavity 44, and the finger cylinder 35 picks up the drawer 21 containing the required instruments.
[0039] c. The first pneumatic sealing door 20 is opened, and the first material handling component 29 sends the drawer 21 into the disinfection chamber 19 and places it inside the disinfection chamber 39.
[0040] d. The first pneumatic sealing door 20 is closed, and the disinfection chamber 39 begins sealed disinfection (e.g., UVC irradiation for a preset time).
[0041] e. After disinfection, the second material handling component 41 removes the drawer 21 from the disinfection chamber 39 and places it on the push plate 38 of the feeding structure 42.
[0042] f. When the lifting and sealing door 32 is opened, the electric push rod B40 pushes the push plate 38, sending the drawer 21 into the batching bin 11 through the conveying channel 33.
[0043] g. The lifting and sealing door 32 is closed. The weighing sensor 30 and the scanning light curtain 31 in the batching bin 11 automatically verify the weight and profile of the instruments in the drawer.
[0044] h. After verification, the electrically sealed door of the batching silo 11 is unlocked, and the LED indicator light prompts the operator to open the silo door and retrieve the equipment. Wide-angle camera 36 records this operation.
[0045] i. After the ingredients are used up, the empty drawer is returned to the mixing hopper, and the system sends it back to its original position in the storage chamber.
[0046] 2. Emergency retrieval procedure:
[0047] In case of emergency, medical personnel can directly press the emergency button 14 on the cabinet. The intelligent control system 43 (or independent emergency circuit) will respond immediately, opening the second sealed door 15 and activating the electric push rod A28 to quickly push out the emergency kit storage chamber 27, which is pre-loaded with first aid equipment. The entire process can be completed within seconds, completely unaffected by other tasks of the main system.
[0048] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
