Description

Technical Field

[0001] This invention belongs to the field of medical device storage technology, and particularly relates to a medical device storage box for operating room care. Background Technology

[0002] In operating room nursing, the standardized storage and aseptic management of medical instruments are crucial for preventing postoperative infections and ensuring surgical safety. During surgery, nurses need to frequently handle sterile instruments and properly store contaminated instruments after use to prevent cross-contamination.

[0003] Currently, commonly used medical device storage boxes for operating room nursing have significant technical defects. In terms of the storage and management of sterile and contaminated instruments, existing storage boxes only use partitions or trays for simple partitioning. Blood, tissue fluid, and various pathogens attached to used instruments can easily contaminate unused sterile instruments through airflow, physical collisions between instruments, or indirect contact with the gloves of operators, thus creating a serious risk of cross-infection.

[0004] Alternatively, during the retrieval and placement of instruments, existing storage boxes generally use simple flip-top or rubber baffle structures for their openings, resulting in direct communication between the interior of the chamber and the operating room environment during operation. This design makes it easy for sterile gases or the sterile environment within the sterile chamber to leak, affecting the sterility maintenance of remaining instruments; at the same time, when contaminated instruments are placed, contaminants on the instrument surface may form tiny aerosol particles that escape into the air, polluting the air environment of the operating room.

[0005] In conclusion, existing storage boxes urgently need systematic improvements in terms of structural zoning, sealing design, fixing methods, and intelligent monitoring. Summary of the Invention

[0006] The purpose of this invention is to provide a medical device storage box for operating room care, which aims to solve the above-mentioned problems.

[0007] This invention is implemented as follows: a medical device storage box for operating room care includes a box body. Inside the box body are a sterile tank and a contaminated isolation tank. The bottom surfaces of both the sterile tank and the contaminated isolation tank are rotatably connected to limiting plates. Each limiting plate is connected to a drive assembly that rotates it. A sterile storage cylinder and an isolation storage cylinder are respectively disposed in the sterile tank and the contaminated isolation tank. The sterile storage cylinder and the isolation storage cylinder are vertically slidably connected to their respective limiting plates. Partitions are evenly spaced in both the sterile storage cylinder and the isolation storage cylinder, naturally forming fan-shaped grooves between the partitions. A thin film can be fitted over the outside of both the sterile storage cylinder and the isolation storage cylinder. A cover plate assembly and a sealing assembly are respectively fitted over the upper parts of both the sterile storage cylinder and the isolation storage cylinder. Both the cover plate assembly and the sealing assembly can separate and fix the thin film above each fan-shaped groove. The sealing assembly can seal the upper part of the isolation storage cylinder. The upper parts of the sterile tank and the contaminated isolation tank are respectively connected to a first disinfection chamber and a second disinfection chamber. Both the first and second disinfection chambers have open rubber sleeves near their top positions. Inside each of the first and second disinfection chambers, two sealing plates are rotatably connected via a first elastic torsion spring. Electromagnets are distributed at the bottom of each limiting plate, used to magnetically fix the sterile storage cylinder, the isolation storage cylinder, and the medical devices contained therein. Both the sterile tank and the contaminated isolation tank are equipped with a control system, which can control the electromagnetic force of the electromagnets according to the operating status of the sterile storage cylinder or the isolation storage cylinder.

[0008] A further technical solution includes a limiting cover, a first threaded sleeve in the middle of the limiting cover, a limiting rod fixedly installed in the middle of both the sterile storage cylinder and the isolation storage cylinder, the first threaded sleeve being threadedly connected to the limiting rod, and the port of the sterile storage cylinder covered with a film being pressed and sealed between the first threaded sleeve and the limiting rod, the limiting cover having a first slot at equal intervals, each of the first slots being able to engage with the upper end of the internal partition of the sterile storage cylinder, and an retrieval hole being opened on the limiting cover corresponding to the position of each fan-shaped slot.

[0009] A further technical solution includes a sealing cap with a second threaded sleeve rotatably disposed in the center of the sealing cap. The second threaded sleeve can be threadedly connected to a limiting rod in the center of the isolation storage cylinder, and the port of the isolation storage cylinder covered with a film can be pressed and sealed between the second threaded sleeve and the limiting rod. The sealing cap has second slots evenly spaced, which can engage with the upper end of the internal partition of the isolation storage cylinder. A placement hole is provided between two adjacent second slots. A sealing groove is provided on the side of the placement hole near the isolation storage cylinder. Two flip-top plates are rotatably connected in the sealing groove through a second elastic torsion spring. A limiting groove is provided on the side of the flip-top plate facing the placement hole, and a silicone self-healing film is provided in the limiting groove.

[0010] In a further technical solution, a connecting sleeve connects the first disinfection chamber and the second disinfection chamber. A self-locking rod is slidably connected in the connecting sleeve. A spring connects the self-locking rod to the connecting sleeve. Both ends of the self-locking rod extend into the first disinfection chamber and the second disinfection chamber, respectively, and both ends of the self-locking rod are located on the closing stroke path of the sealing plate.

[0011] In a further technical solution, both the first and second elastic torsion springs are SMA springs, and a miniature normally closed micro switch is provided on one side of the sealing plate and the flip cover. When the sealing plate or the flip cover is closed, the micro switch is pressed down and its normally closed contact is open.

[0012] In a further technical solution, a disinfection gas generator is connected inside the first disinfection chamber, and an ultraviolet irradiation lamp is installed in the second disinfection chamber.

[0013] In a further technical solution, the drive component includes a motor and a gear transmission pair. The motor is fixedly connected to the housing, and a gear transmission pair is provided between the output shaft of the motor and the limiting plate.

[0014] A further technical solution is provided, wherein the control system includes: Data acquisition module: It is used to acquire the vertical vibration intensity, overall weight and horizontal oscillation frequency of the sterile storage tube or isolation storage tube, and substitute the above parameters into the maximum-minimum normalization formula for normalization processing. Data processing module: Substitutes the normalized values ​​of vertical vibration intensity, overall weight, and horizontal oscillation frequency of the sterile storage cylinder or isolation storage cylinder from the data acquisition module, along with the initially set electromagnetic intensity, into the preset model for calculation, and outputs the optimized electromagnetic intensity value. Control module: Based on the electromagnetic strength optimization value output by the data processing module, control and adjust the electromagnetic force of the electromagnet in real time.

[0015] A further technical solution is that the preset model is: The optimized electromagnetic strength value is equal to the initial electromagnetic strength multiplied by (1 plus the product of the normalized value of vertical vibration intensity and the first weighting coefficient, plus the product of the normalized value of overall weight and the second weighting coefficient, plus the product of the normalized value of horizontal oscillation frequency and the third weighting coefficient), where each weighting coefficient is a positive number and their sum is 1.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a medical device storage box for operating room care, achieving independent sealing of membrane zones to avoid cross-contamination. Specifically, a replaceable membrane is fitted around the outside of the sterile storage cylinder and the isolation storage cylinder, and the membrane ends are pressed and sealed by a cover assembly or sealing assembly. Simultaneously, the use of slots and partitions allows for independent sealing of the membrane above each sector-shaped slot. When the membrane in one sector-shaped slot breaks during instrument retrieval, the membranes in the remaining sector-shaped slots remain intact and sealed, effectively preventing all instruments from being exposed to contamination risks due to frequent retrieval, and significantly improving the reliability of aseptic maintenance and contamination isolation.

[0017] This invention provides a medical device storage box for operating room care, which facilitates quick cleaning and film replacement, improving care efficiency. Specifically, the film acts as a disposable isolation barrier, completely isolating the medical devices from the inner wall of the storage box. After surgery, simply remove the film along with the internal instruments for quick replacement with a new film, eliminating the need for complex disinfection of the storage box, significantly simplifying the cleaning process and improving the efficiency of operating room care.

[0018] This invention provides a medical device storage box for operating room care. Electromagnetic adsorption effectively protects the film, preventing damage. Specifically, the electromagnet at the bottom of the limiting plate, under the control of the regulation system, can adjust the electromagnetic force in real time according to dynamic parameters such as the vibration, weight, and oscillation frequency of the storage cylinder. Appropriate electromagnetic adsorption force can prevent rigid collisions between the storage cylinder and the box body during rotation or placement, thereby effectively reducing the risk of film damage due to friction or impact, ensuring the integrity of the film's seal, and extending the single sterility maintenance period.

[0019] This invention provides a medical device storage box for operating room care, featuring an adaptive electromagnetic fixation system that balances stability and safety. Specifically, through a data acquisition module, a data processing module, and a preset electromagnetic strength optimization model, the system dynamically outputs the optimal electromagnetic force, ensuring the storage cylinder receives suitable adsorption force under light load, heavy load, stationary, or rotating conditions. This adaptive mechanism guarantees stable fixation of the storage cylinder and internal instruments, preventing shaking or tipping, while also avoiding excessive magnetic force that could cause the membrane to be stretched or deformed, achieving an intelligent balance between fixation strength and membrane protection.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4As shown, an embodiment of the present invention provides a medical device storage box for operating room care, comprising a box body 1. Inside the box body 1 are a sterile tank 2 and a contaminated isolation tank 3. The bottom surfaces of both the sterile tank 2 and the contaminated isolation tank 3 are rotatably connected to a limiting plate 4. Each limiting plate 4 is connected to a driving assembly 5 that rotates it intermittently. A sterile storage cylinder 15 and an isolation storage cylinder 16 are respectively disposed in the sterile tank 2 and the contaminated isolation tank 3. The sterile storage cylinder 15 and the isolation storage cylinder 16 are vertically slidably connected to corresponding... In the limiting plate 4, the sterile storage cylinder 15 and the isolation storage cylinder 16 are provided with partitions 11 at equal intervals, and fan-shaped grooves are naturally formed between the partitions 11. The sterile storage cylinder 15 and the isolation storage cylinder 16 can be covered with a film. The upper part of the sterile storage cylinder 15 and the isolation storage cylinder 16 are respectively covered with a cover plate assembly 8 and a sealing assembly 9. The cover plate assembly 8 and the sealing assembly 9 can separate and fix the film above each fan-shaped groove. The sealing assembly 9 can seal the upper part of the isolation storage cylinder 16. The upper parts of the sterile tank 2 and the contaminated isolation tank 3 are respectively connected to a first disinfection chamber 13 and a second disinfection chamber 14. The first disinfection chamber 13 and the second disinfection chamber 14 are provided with open rubber sleeves 12 near the top. The interior of the first disinfection chamber 13 and the second disinfection chamber 14 are rotatably connected to two covered sealing plates 61 by a first elastic torsion spring. Electromagnets 17 are distributed at the bottom of the limiting plate 4. The electromagnets 17 are used to magnetically fix the sterile storage cylinder 15 and the isolation storage cylinder 16 and the medical devices therein. The sterile tank 2 and the contaminated isolation tank 3 are both equipped with a control system. The control system can control the electromagnetic force of the electromagnets 17 according to the operating status of the sterile storage cylinder 15 or the isolation storage cylinder 16.

[0025] In this embodiment, the working process is as follows: First, the sterile slot 2 and the contaminated isolation slot 3 inside the housing 1 provide physical isolation, ensuring that sterile instruments and contaminated instruments are stored in separate areas. When user A needs to retrieve a sterile scalpel, the sterile storage cylinder 15 drives the limiting plate 4 to rotate intermittently through the drive component 5, rotating the fan-shaped slot storing the scalpel to below the first disinfection chamber 13. At this time, the film covering the outside of the sterile storage cylinder 15 and the cover assembly 8 together maintain a sterile environment. User A puts his hand into the open rubber sleeve 12 at the top of the first disinfection chamber 13. The elasticity of the rubber sleeve 12 causes it to expand when the hand is put in and contract when it is taken out, thereby limiting the entry of external air to a certain extent. During the process of retrieving the scalpel, since the cover assembly 8 separates and fixes the film above each fan-shaped slot, retrieving the scalpel only causes the film above the scalpel to break, while the film above the other fan-shaped slots remains sealed, avoiding cross-contamination of all surgical instruments caused by frequent retrieval of surgical instruments.

[0026] Subsequently, when user A needs to dispose of contaminated dressings, the isolation collection cylinder 16, driven by the drive component 5, rotates the limiting plate 4 to rotate the corresponding sector groove below the second disinfection chamber 14. The film covering the outside of the isolation collection cylinder 16 and the sealing component 9 work together to isolate the contaminated instruments. User A inserts the contaminated dressing into the isolation collection cylinder 16 through the open rubber sleeve 12 at the top of the second disinfection chamber 14. The sealing component 9 not only secures and tightens the film but also seals the upper part of the isolation collection cylinder 16, effectively preventing the escape of contaminated aerosols.

[0027] Throughout the operation, the electromagnet 17 at the bottom of the limiting plate 4 magnetically holds the sterile storage cylinder 15 and the isolation storage cylinder 16 in place, preventing them from shaking during rotation or placement. More importantly, the control system can control the electromagnetic force of the electromagnet 17 in real time according to the operating status of the storage cylinder (e.g., when the storage cylinder vibrates slightly due to the handling of instruments). For example, when the control system detects that the storage cylinder is stationary and ready to be handled, it can appropriately reduce the electromagnetic force to facilitate the user A's handling of instruments; when the storage cylinder is rotating or under heavy load, the control system can increase the electromagnetic force to ensure the stable fixation of the storage cylinder and prevent instruments from colliding or tipping over. In addition, the two sealing plates 61 inside the first sterilization chamber 13 and the second sterilization chamber 14 automatically close during non-operation periods through the action of the first elastic torsion spring, sealing the inside of the sterilization chamber and further ensuring the maintenance of a sterile environment and the isolation of contaminants.

[0028] like Figure 7 As shown, in a preferred embodiment of the present invention, the cover assembly 8 includes a limiting cover 81, a first threaded sleeve 83 is provided in the middle of the limiting cover 81, a limiting rod 10 is fixedly provided in the middle of both the sterile storage cylinder 15 and the isolation storage cylinder 16, the first threaded sleeve 83 can be threadedly connected to the limiting rod 10, and the port of the sterile storage cylinder 15 covered with a film can be pressed and sealed between the first threaded sleeve 83 and the limiting rod 10, the limiting cover 81 is provided with a first slot 82 at equal intervals, the first slot 82 can be engaged with the upper end of the internal partition 11 of the sterile storage cylinder 15, and an object retrieval hole 84 is provided on the limiting cover 81 corresponding to the position of each fan-shaped slot.

[0029] In this embodiment, the cover assembly 8 of this application, through its ingenious structural design, aims to solve the problems of poor film sealing, easy loosening, and high operating noise in traditional storage boxes during instrument handling. When it is necessary to seal the sterile storage cylinder 15, the operator folds the film port that is fitted onto the outside of the sterile storage cylinder 15 upwards, so that it covers the top area of ​​the limiting rod 10. Then, the limiting cap 81 is placed above the sterile storage cylinder 15, so that the first threaded sleeve 83 in the middle of the limiting cap 81 is aligned with the limiting rod 10. By rotating the limiting cap 81, the first threaded sleeve 83 is threadedly connected to the limiting rod 10. During the tightening process, the film port is evenly and firmly pressed between the first threaded sleeve 83 and the limiting rod 10, forming a reliable physical seal. This threaded pressing mechanism provides adjustable sealing pressure, ensuring that the film port will not loosen, effectively preventing external contaminants from entering the interior of the sterile storage cylinder 15, while preventing leakage of internal sterilization gas.

[0030] Furthermore, the number one slot 82, evenly spaced on the limiting cover 81, engages with the upper end of the partition 11 inside the sterile storage cylinder 15. This not only further stabilizes the connection between the cover assembly 8 and the storage cylinder but also fixes the position of the partition 11, reducing the shaking and collision of internal instruments when the storage cylinder rotates or moves, thereby reducing noise. Simultaneously, the engagement of the number one slot 82 with the partition 11 allows the membrane to independently seal each sector. When the membrane above a certain sector breaks, the remaining sector maintains a sterile environment.

[0031] When instruments need to be retrieved, the operator does not need to fully open the cover assembly 8. They can simply use the retrieval holes 84 on the limiting cover 81 corresponding to each sector slot position. This minimizes the contact between the sterile environment and the outside, maintaining the stability of the sterile state. This design, together with the sterile tank 2 inside the housing 1, creates an efficient and safe sterile instrument management environment.

[0032] like Figures 8-10As shown, in a preferred embodiment of the present invention, the sealing assembly 9 includes a sealing cover 91, a second threaded sleeve 92 rotatably disposed in the middle of the sealing cover 91, the second threaded sleeve 92 being threadedly connected to the limiting rod 10 in the middle of the isolation storage cylinder 16, and the port of the isolation storage cylinder 16 covered with a film can be pressed and sealed between the second threaded sleeve 92 and the limiting rod 10. The sealing cover 91 is provided with second slots 96 at equal intervals, the second slots 96 being able to engage with the upper end of the internal partition 11 of the isolation storage cylinder 16, and a placement hole 93 is provided between two adjacent second slots 96. A sealing groove 94 is provided on the side of the placement hole 93 near the isolation storage cylinder 16, and two closed flip-top plates 95 are rotatably connected in the sealing groove 94 through a second elastic torsion spring. A limiting groove 97 is provided on the side of the flip-top plate 95 facing the placement hole 93, and a silicone self-healing film is disposed in the limiting groove 97.

[0033] In this embodiment, the solution of this application achieves a reliable seal on the upper part of the isolation storage cylinder 16 by optimizing the structural design of the sealing component 9, and solves the problems of insufficient sealing, large closing impact, obvious noise, and decreased sealing performance after long-term use during instrument handling. Specifically, the sealing cover 91, as an integral covering structure, provides basic protection for the isolation storage cylinder 16. It is connected to the limiting rod 10 in the middle of the isolation storage cylinder 16 by a threaded sleeve 92 that is rotated in the middle, thereby firmly pressing and sealing the membrane port of the isolation storage cylinder 16 between the threaded sleeve 92 and the limiting rod 10. This pressing and sealing method can effectively prevent contaminants from escaping and ensure the isolation of the internal environment of the isolation storage cylinder 16. At the same time, the second slots 96 that are equally spaced on the sealing cover 91 engage with the upper end of the partition 11 inside the isolation storage cylinder 16, which not only ensures the accurate installation and stable connection of the sealing cover 91, but also stabilizes the internal structure of the storage cylinder and prevents the instrument from affecting the sealing effect due to shaking during operation.

[0034] To facilitate the placement of contaminated instruments, the sealing cap 91 has placement holes 93 between two adjacent slots 96. To address the sealing issue during placement, a sealing groove 94 is provided on the side of the placement hole 93 near the isolation storage cylinder 16. Two closing flip-top plates 95 are rotatably connected to the sealing groove 94 via a second elastic torsion spring. When instruments need to be placed, the operator can insert the instrument through the placement hole 93. The flip-top plates 95 automatically open under the pushing force. After placement, the elastic force of the second elastic torsion spring drives the flip-top plates 95 to close automatically and smoothly, effectively reducing the impact and noise during closing. Furthermore, a limiting groove 97 is provided on the side of the flip-top plate 95 facing the placement hole 93, and a silicone self-healing membrane is provided in the limiting groove 97. When the flip-top plate 95 is closed, the silicone self-healing membrane forms a self-healing sealing barrier under the pressure of the edge of the placement hole 93. Even after multiple instrument punctures and placements, the silicone self-healing membrane can automatically close the tiny pores, thereby maintaining the sealing performance for a long time and effectively preventing the spread of contaminants.

[0035] Through the above structural combination, the sealing component 9 and the isolation storage cylinder 16 work together to provide an efficient, reliable, and easy-to-operate sealed storage environment for contaminated instruments within the contamination isolation groove 3 inside the housing 1. This design not only improves the sealing reliability during instrument placement and reduces the risk of cross-infection, but also enhances the user experience through a buffer closing mechanism and extends the service life of the sealing structure.

[0036] like Figure 4 As shown, in a preferred embodiment of the present invention, a connecting sleeve 62 is connected between the first disinfection chamber 13 and the second disinfection chamber 14. A self-locking rod 63 is slidably connected in the connecting sleeve 62. A spring is connected between the self-locking rod 63 and the connecting sleeve 62. Both ends of the self-locking rod 63 extend into the first disinfection chamber 13 and the second disinfection chamber 14, respectively, and both ends of the self-locking rod 63 are located on the closing stroke path of the sealing plate 61.

[0037] In this embodiment, the present application constructs a sophisticated mechanical interlocking mechanism by introducing a connecting sleeve 62, a self-locking rod 63, and a spring to ensure that the sealing plates 61 of the first disinfection chamber 13 and the second disinfection chamber 14 cannot be in the open state simultaneously. Specifically, the connecting sleeve 62 acts as a physical bridge, connecting the first disinfection chamber 13 and the second disinfection chamber 14, and providing a restricted sliding channel for the self-locking rod 63. The self-locking rod 63 is slidably connected inside the connecting sleeve 62, with its two ends extending into the first disinfection chamber 13 and the second disinfection chamber 14 respectively, and precisely positioned on the closing stroke path of their respective sealing plates 61. The spring is connected to the self-locking rod 63, providing it with a continuous restoring force, keeping it in a preset position without external intervention. When the operator needs to open the sealing plate 61 of the first disinfection chamber 13, the sealing plate 61 pushes one end of the self-locking rod 63 during the opening process. As the self-locking lever 63 slides within the connecting sleeve 62, this pushing force causes the other end of the self-locking lever 63 to extend into the second disinfection chamber 14, occupying the closing stroke path of the sealing plate 61 of the second disinfection chamber 14. At this point, even if the operator attempts to open the sealing plate 61 of the second disinfection chamber 14, it will be blocked by the extended end of the self-locking lever 63, thus preventing the opening action from being completed. Conversely, when the sealing plate 61 of the second disinfection chamber 14 is opened, the other end of the self-locking lever 63 will extend into the first disinfection chamber 13, preventing the sealing plate 61 of the first disinfection chamber 13 from being opened. This design cleverly utilizes the principle of mechanical linkage to forcibly interlock the operating ports of the two disinfection chambers. Combined with the sterile tank 2 and the contaminated isolation tank 3 inside the housing 1, as well as their respective disinfection chambers 13 and 14, it forms a safer isolation environment.

[0038] Through this interlocking mechanism, this application effectively avoids the possibility of the operator accidentally opening two sterilization chambers at the same time, thereby fundamentally eliminating the risk of cross-contamination between sterile instruments and contaminated instruments, and greatly improving the safety and reliability of the medical device storage box for operating room nursing.

[0039] In a preferred embodiment of the present invention, both the first elastic torsion spring and the second elastic torsion spring are SMA springs. A micro normally closed micro switch is provided on one side of the sealing plate 61 and the flip cover 95. When the sealing plate 61 or the flip cover 95 is closed, the micro switch is pressed down and its normally closed contact is open.

[0040] In this embodiment, the SMA spring, or shape memory alloy spring, is a spring made of shape memory alloy material. This type of alloy can recover its preset shape at a specific temperature, exhibiting a shape memory effect or superelasticity. Compared to traditional metal springs, SMA springs have higher energy density, longer fatigue life, and more stable elastic restoring force.

[0041] This application's solution significantly improves the sealing reliability and intelligent monitoring capabilities of the operating room nursing medical device storage box by replacing the first and second elastic torsion springs with SMA springs and supplementing them with miniature normally closed microswitches. Specifically, in the first disinfection chamber 13 and the second disinfection chamber 14 above the sterile tank 2 and the contaminated isolation tank 3, the closing action of the sealing plate 61 is driven by the SMA spring. When the sealing plate 61 needs to be closed, the SMA spring utilizes its shape memory effect or superelasticity to provide a stable and durable restoring force, ensuring that the sealing plate 61 can close smoothly and forcefully, thereby effectively isolating the internal environment of the disinfection chamber and preventing the leakage of disinfection gas or the entry of external contaminants. At the same time, in the sealing assembly 9 at the top of the isolation storage cylinder 16, the closing of the flip cover 95 is also driven by the SMA spring, ensuring that the placement hole 93 can be reliably sealed when not in use, preventing the spread of contamination.

[0042] To further ensure the reliability of the seal, this design incorporates miniature normally closed microswitches on one side of both the sealing plate 61 and the flip cover 95. When either the sealing plate 61 or the flip cover 95 is fully closed, its structure precisely presses down the corresponding miniature normally closed microswitch. At this time, the normally closed contact of the microswitch switches from the closed state to the open state, generating a clear electrical signal. This signal can be received and processed by the control system of the enclosure 1, thereby confirming in real time whether the sealing plate 61 and the flip cover 95 are fully closed and sealed. This real-time feedback mechanism solves the problem of the inability to automatically detect the sealing status in traditional solutions, avoiding incomplete sealing due to operational negligence or mechanical failure, and greatly improving the safety of maintaining a sterile environment and isolating contaminants.

[0043] Through the aforementioned technical means, the introduction of SMA springs ensures the durability and response accuracy of the elastic element, avoiding fatigue failure, closing force attenuation, and resulting impact and noise problems caused by long-term use of traditional springs, thus making the sealing action more stable and reliable. The miniature normally closed microswitch provides an intelligent means of detecting the sealing status of the enclosure 1, enabling the control system to monitor and verify the sealing status in real time. This provides a higher level of safety and operational convenience for the operating room throughout the entire process of medical device storage, sterilization, and isolation.

[0044] like Figure 4 As shown, in a preferred embodiment of the present invention, a disinfection gas generator 7 is connected inside the first disinfection chamber 13, and an ultraviolet irradiation lamp is provided in the second disinfection chamber 14.

[0045] In this embodiment, the solution of this application achieves differentiated disinfection for different types of medical devices through the aforementioned technical means. Specifically, a disinfection gas generator 7 is connected inside the first disinfection chamber 13 to generate chemical disinfection gas, which continuously and gently disinfects the sterile instruments in the sterile tank 2, ensuring the maintenance of a sterile environment and avoiding disinfection gas leakage or insufficient effectiveness. Simultaneously, an ultraviolet irradiation lamp is installed in the second disinfection chamber 14 to rapidly and efficiently sterilize the contaminated instruments in the contamination isolation tank 3 using ultraviolet radiation, reducing the risk of aerosol contamination and avoiding chemical residues. This combination fully utilizes the physical isolation characteristics of the sterile tank 2 and the contamination isolation tank 3 inside the housing 1, as well as the independent disinfection spaces of the first and second disinfection chambers 14, providing the most suitable disinfection environment and method for different types of medical devices. The synergistic effect of the disinfection gas generator 7 and the ultraviolet irradiation lamp allows the entire housing 1 to simultaneously meet the needs of maintaining the sterility of sterile instruments and effectively decontaminating contaminated instruments, avoiding the limitations of a single disinfection method and effectively solving the problem of a lack of specific disinfection methods.

[0046] like Figure 3 As shown, in a preferred embodiment of the present invention, the drive assembly 5 includes a motor 51 and a gear transmission pair 52. The motor 51 is fixedly connected to the housing 1, and a gear transmission pair 52 is provided between the output shaft of the motor 51 and the limiting disk 4.

[0047] In this embodiment, a gear transmission pair 52 is provided between the output shaft of the motor 51 and the limiting disk 4. This means that the rotational power generated by the motor 51 is first transmitted to the gear transmission pair 52 through its output shaft, and then the gear transmission pair 52 transmits the power to the limiting disk 4. When the motor 51 starts, the torque it generates is precisely transmitted through the gear transmission pair 52 and may be appropriately decelerated or increased in torque, ultimately driving the limiting disk 4 to rotate intermittently. This design makes the rotation of the limiting disk 4 more stable and precise, effectively avoiding the shaking or eccentricity of the sterile storage cylinder 15 or the isolation storage cylinder 16 during the positioning process due to unstable drive, thereby ensuring the stable storage and safe operation of medical devices.

[0048] In a preferred embodiment of the present invention, the control system includes: Data acquisition module: It is used to acquire the vertical vibration intensity, overall weight and horizontal oscillation frequency of the sterile storage tube 15 or the isolation storage tube 16, and substitute the above parameters into the maximum-minimum normalization formula for normalization processing. Data processing module: Substitutes the normalized value of vertical vibration intensity, normalized value of overall weight, and normalized value of horizontal oscillation frequency of the sterile storage cylinder 15 or isolation storage cylinder 16 in the data acquisition module, along with the initially set electromagnetic intensity, into the preset model for calculation, and outputs the optimized electromagnetic intensity value. Control module: Based on the electromagnetic strength optimization value output by the data processing module, control and adjust the electromagnetic force of electromagnet 17 in real time.

[0049] In this embodiment, the data acquisition module can use a triaxial accelerometer (e.g., a MEMS accelerometer) installed below the limiting plate 4 to monitor the vertical vibration intensity and horizontal oscillation frequency of the sterile storage cylinder 15 or the isolation storage cylinder 16 in real time. Simultaneously, a high-precision weighing sensor (e.g., a piezoelectric or strain gauge weighing sensor) is integrated below the support structure of the limiting plate 4 to obtain the overall weight of the storage cylinder. The raw data collected by these sensors is converted into digital signals by an analog-to-digital converter and input to the data processing module.

[0050] In the data processing module, an STM32 series microcontroller can be used as the core processor. This microcontroller first executes a max-min normalization algorithm to map the sensor data to a range of 0 to 1. Subsequently, the microcontroller substitutes the normalized vibration intensity value, weight value, oscillation frequency value, and a preset initial electromagnetic intensity (e.g., set according to the maximum design load of the storage tube) into a preset mathematical model for calculation.

[0051] The control module can be directly controlled by the STM32 microcontroller, which drives a power MOSFET or H-bridge circuit through its PWM output pin. This circuit is connected to the electromagnet 17. Based on the electromagnetic strength optimization value output by the data processing module, the microcontroller adjusts the duty cycle of the PWM signal in real time, thereby precisely controlling the current flowing through the electromagnet 17 and thus adjusting the magnetic strength of the electromagnet 17.

[0052] This application's solution addresses the issue of inaccurate electromagnetic force adjustment by constructing an intelligent control system, achieving adaptive optimization. Specifically, the data acquisition module acquires vertical vibration intensity, overall weight, and horizontal oscillation frequency, and performs normalization using a maximum-minimum normalization formula, ensuring the comparability and consistency of different parameters and providing a standardized basis for subsequent calculations. The data processing module substitutes the normalized vertical vibration intensity, overall weight, and horizontal oscillation frequency values, along with the initially set electromagnetic intensity, into a preset model for calculation. The model comprehensively considers multiple dynamic factors, achieving intelligent decision-making and outputting optimized values. The control module adjusts the electromagnetic force of electromagnet 17 in real time based on the output optimized electromagnetic intensity value, ensuring dynamic response and stability and avoiding the risks of insufficient or excessive fixation. Overall, these modules work together to overcome the shortcomings of simple adjustment and improve the device's fixation effect. The control system works in conjunction with the electromagnet 17 installed inside the housing 1 to dynamically adjust the attraction force of the electromagnet 17 according to the actual operating state (such as vibration, weight, and sway) of the sterile storage cylinder 15 or the isolation storage cylinder 16. This ensures that the storage cylinder and the medical devices inside are stably and reliably fixed under various working conditions, effectively preventing the shaking, collision, or tipping of the devices, and further ensuring the sterility and safety of the medical devices.

[0053] As a preferred embodiment of the present invention, the model is as follows: ; in To initially set the electromagnetic intensity, This is the normalized value of the vertical vibration intensity. This is the normalized value for the overall weight. This is the normalized value of the horizontal oscillation frequency. , as well as These are weighting coefficients, and all are positive. , This is the optimized value for electromagnetic intensity.

[0054] In this embodiment, the model is a mathematical expression used to describe and predict system behavior, specifically referring to the mathematical relationship used to calculate the electromagnetic force required for electromagnet 17. It can be implemented in a microcontroller or embedded system using a programming language. By comprehensively considering multiple influencing factors, this model can provide an accurate and adaptive electromagnetic force calculation result.

[0055] Initial electromagnetic strength setting This refers to the reference electromagnetic force that electromagnet 17 should provide when there is no external interference or load change. This value can be preset according to the general design requirements and typical usage scenarios of the storage box. For example, a minimum electromagnetic force that can stably fix the storage tube 15 or the isolation storage tube 16 under no-load or light-load conditions can be determined through experimental testing, or it can be set to a user-configurable default value.

[0056] Normalized value of vertical vibration intensity , is a dimensionless parameter that measures the intensity of vertical vibration of the storage tube 15 or the isolation storage tube 16. This value can be obtained by mapping the original vibration data to the range of 0 to 1 using the maximum-minimum normalization method, or by calculating the ratio of the real-time measured vertical vibration amplitude or root mean square value to a preset maximum vibration threshold.

[0057] Overall weight normalized value , is a dimensionless parameter representing the total weight of the storage cylinder 15 or the isolation storage cylinder 16 and the medical devices inside. This value can be obtained by mapping the raw weight data to the range of 0 to 1 using the maximum-minimum normalization method, or by calculating the ratio of the real-time measured total weight to the maximum load-bearing capacity of the storage cylinder 15 or the isolation storage cylinder 16.

[0058] Normalized value of horizontal oscillation frequency , is a dimensionless parameter that measures the horizontal oscillation frequency of the storage tube 15 or the isolation storage tube 16. This value can be obtained by mapping the original frequency data to the range of 0 to 1 using the maximum-minimum normalization method, or by calculating the ratio of the real-time measured horizontal oscillation frequency to the preset maximum oscillation frequency.

[0059] Weighting coefficient , as well as It is used for adjustment , and exist Numerical factors that play a significant role in the calculation. These coefficients can be pre-calibrated experimentally, set by expert experience, or trained on a large amount of operational data using machine learning algorithms (such as regression analysis). They allow the system to be assigned different sensitivities to different types of dynamic changes (vibration, weight, oscillation) according to actual needs. The constraints ensure that the sum of all weight coefficients is 1, which makes the adjustment factor... Able to balance the initial electromagnetic intensity The corrections were made to avoid overcompensation or undercompensation caused by improper weight allocation.

[0060] Electromagnetic strength optimization value This is the final electromagnetic force setting value for real-time control of the electromagnet 17, calculated based on the aforementioned model. This value is dynamically changing and can be adjusted according to the actual operating state of the storage tube 15 or the isolation storage tube 16 to ensure optimal fixing effect.

[0061] The maximum-minimum formula is: ,in These are the original input parameters. The lower limit value of the input parameter is set. The upper limit value of the input parameters is set. This is the output value. The maximum-minimum formula is a commonly used data normalization method, which aims to transform data with different dimensions or different numerical ranges into a unified, preset interval, such as [0, 1] or [-1, 1].

[0062] Through the above technical solution, this application provides a clear and operable mathematical model for accurately calculating the optimized electromagnetic strength value. This model can adaptively adjust the electromagnetic force of the electromagnet 17 based on multiple dynamic parameters, such as the vertical vibration intensity, overall weight, and horizontal oscillation frequency of the storage cylinder 15 or the isolation storage cylinder 16. This effectively solves the problem of traditional storage boxes having a single electromagnetic force fixing method that cannot adapt to different loads and dynamic conditions, significantly improving the stability of the storage cylinder 15 or the isolation storage cylinder 16 in both rotating and stationary states, and avoiding situations where instruments collide, tip over, or are difficult to retrieve or place. Simultaneously, through flexible configuration of weighting coefficients, this solution can better adapt to the needs of different surgical scenarios and instrument types, improving the intelligence level and reliability of the medical device storage box.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
