Description

Technical Field

[0001] This invention belongs to the field of medical and nursing auxiliary equipment technology, specifically a clinical medical and nursing medication preparation and disinfection device. Background Technology

[0002] In modern clinical medical and nursing work, medication preparation is an extremely critical and frequent step. In the traditional medication preparation process, the accurate dosage, the uniformity of mixing, and the maintenance of a sterile environment have a crucial impact on treatment efficacy and patient safety.

[0003] Currently, medication preparation and sterilization in clinical medical care largely rely on manual operation and simple auxiliary tools. Medical staff typically need to remove medications from their original packaging, measure and mix them using syringes or similar tools, and then sterilize the used instruments and packaging containers after preparation. These instruments include syringes, capped glass vials, and ampoules. Traditional sterilization methods involve alcohol wiping and ultraviolet irradiation. These methods have significant drawbacks: firstly, manual operation consumes a large amount of manpower and time, resulting in low efficiency; secondly, it is difficult to ensure comprehensive sterilization, easily creating sterilization blind spots in grooves, crevices, and other areas of the instruments.

[0004] To address the shortcomings of manual disinfection, automated disinfection devices have emerged in existing technologies. For example, patent document CN114917389A discloses an atomizing disinfection device that attempts to reduce disinfection blind spots and residues in ampoules by optimizing the atomization structure. However, this solution still has significant drawbacks: First, the fixed disinfection structure can only disinfect the surface of the ampoule. When dealing with irregularly shaped instruments such as syringes and dispensing bottles, the grooves, gaps, and bottoms of these instruments are easily blocked, preventing the atomized medication from making sufficient contact and creating disinfection blind spots. Second, the device lacks a dedicated disinfection residue removal module, leaving disinfectant residues after spraying. Taking chlorine-containing disinfectants as an example, if residual chloride ions are not completely removed, they may react chemically with certain drugs during dispensing, leading to reduced efficacy or even the formation of toxic substances.

[0005] Therefore, it is necessary to propose a method that can carry out all-round and multi-angle disinfection through a flexible movement structure, reduce disinfection blind spots, and treat harmful substances generated during the disinfection process to avoid affecting the quality of medicine preparation and avoid environmental pollution. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a clinical medical and nursing medication preparation and disinfection device. This device overcomes the shortcomings of traditional manual disinfection and existing automated disinfection devices, such as disinfection blind spots and insufficient residue removal when dealing with complex-shaped medication preparation instruments. Through a combination of physical and chemical disinfection methods, and utilizing a flexible and movable mechanical structure, it achieves highly efficient multi-angle and all-around disinfection of medication preparation instruments, significantly reducing disinfection blind spots. Simultaneously, the device will be equipped with a dedicated component for removing disinfection residues, ensuring the cleanliness and safety of the instruments after disinfection and avoiding potential harm to drug efficacy and patient health from disinfection byproducts.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A clinical medical nursing drug preparation and disinfection device includes a disinfection box, a display controller fixedly connected to the outer wall of the disinfection box, a disinfection component and a residual cleaning component fixedly connected inside the disinfection box, and both the disinfection component and the residual cleaning component are signal connected to the display controller.

[0008] The disinfection unit is used to disinfect medicine dispensing equipment through both physical and chemical methods. It achieves all-round disinfection and neutralization of disinfectant through a movable mechanical structure, reducing blind spots in disinfection and residual toxicity of disinfectant.

[0009] The residual cleaning component is used to remove residual disinfectant through drying and reflux collection, and to absorb ozone generated by ultraviolet disinfection, thus preventing changes in the efficacy of the medicine or the generation of toxic substances.

[0010] The basic principle of the solution is as follows: During the disinfection process of medication preparation equipment, the display controller manages the workflow of the disinfection and residual cleaning components. The disinfection component, utilizing a movable mechanical structure, flexibly adjusts the disinfection angle and position according to the shape and size of the medication preparation equipment, integrating physical ultraviolet disinfection and chemical spraying to comprehensively cover the surface of the equipment, especially paying attention to details such as grooves and crevices that are easily missed by traditional disinfection methods. This deeply kills bacteria and viruses, ensuring a sterile environment. After the disinfection operation is completed, the residual cleaning component immediately activates, using a drying function to quickly remove moisture from the surface of the equipment. Simultaneously, it uses a reflux collection device to absorb and treat residual disinfectant, while also absorbing ozone generated during ultraviolet disinfection to prevent adverse reactions between residual ozone and the medication, ensuring that the medication preparation process is undisturbed and guaranteeing the stability and safety of the medication.

[0011] The beneficial effects of the basic solution are: 1. Through the movable mechanical structure, the disinfection components can flexibly adjust the disinfection angle and position. Combining physical ultraviolet disinfection and chemical spraying, it can cover the surface of the dispensing equipment in all directions, especially the grooves, gaps and other details that are easily missed by traditional disinfection methods. This effectively reduces blind spots in disinfection, significantly improves the comprehensiveness and thoroughness of disinfection, and ensures a sterile environment.

[0012] 2. The residue cleaning component features drying and reflux collection functions, effectively removing residual disinfectant and absorbing ozone generated by ultraviolet disinfection. This not only prevents adverse reactions between disinfectant residue and medication, thus preventing changes in efficacy or the generation of toxic substances, but also ensures the stability and safety of the medication preparation process, providing strong protection for patient medication safety.

[0013] 3. The display controller manages the workflow of the disinfection and residual cleaning components, automating the disinfection and cleaning processes. This not only improves work efficiency and reduces the workload of medical staff, but also reduces the risk of human error and enhances the quality of medical care.

[0014] 4. This device is suitable for various types of medication preparation equipment, such as syringes, medication bottles, and ampoules. Through flexible mechanical structure adjustments, it can achieve efficient disinfection and cleaning, and has wide applicability and practicality, meeting the needs of different clinical medical and nursing scenarios.

[0015] 5. By collecting and drying disinfection residues through reflux, environmental pollution from disinfection byproducts is avoided, which meets modern medical environmental protection requirements and helps create a cleaner and safer medical environment.

[0016] Furthermore, the disinfection component includes a first toothed ring, a first annular groove is opened inside the disinfection box, the first toothed ring is slidably engaged with the first annular groove, a second annular groove is opened above the first annular groove, a second toothed ring is slidably engaged in the second annular groove, and the diameter of the second toothed ring is smaller than the diameter of the first toothed ring;

[0017] Both the first and second toothed rings have drive tooth grooves on their inner circumferences. A drive motor is symmetrically installed inside the disinfection box. The output shafts of the drive motors are coaxially and fixedly connected to drive gears, which mesh with their corresponding drive tooth grooves. Support bars are fixedly connected to the top walls of both the first and second toothed rings. Each support bar has a lifting groove inside. A lifting motor is fixedly connected to the bottom of each lifting groove, and a lifting rod is fixedly connected to the top of each lifting groove. Limit gears are rotatably connected to each lifting rod. Lifting gears are coaxially and fixedly connected to the output shafts of the lifting motors. Lifting tooth chains mesh between the corresponding limit gears and lifting gears. Both the drive motors and lifting motors are connected to the display controller.

[0018] The beneficial effects of the basic scheme are: 1. Through the meshing of the first and second gear rings with the drive gear, the drive motor can drive the disinfection component to achieve a horizontal circular motion, covering all directions inside the disinfection box; at the same time, the lifting motor, through the cooperation of the lifting gear and the lifting chain, drives the disinfection component to achieve vertical height adjustment. Combined with horizontal rotation, the disinfection component can flexibly adjust its position and angle in three-dimensional space, realizing multi-angle and all-round disinfection of the dispensing equipment, effectively reducing disinfection blind spots, and improving the comprehensiveness and thoroughness of the disinfection effect.

[0019] 2. Through the precise control of the display controller, the drive motor and the lifting motor work together to achieve precise positioning of the disinfection components in space, ensuring the accuracy of the disinfection operation and meeting the disinfection needs of different types of dispensing instruments.

[0020] Furthermore, a support block is fixedly connected to the outside of the lifting tooth chain located on the first tooth ring. The support block points towards the center of the bottom wall inside the disinfection box. A first electric push rod is fixedly connected to the top wall of the support block. A magnetic platform is hinged to the side of the support block away from the lifting tooth chain. A platform magnet is embedded in the center of the magnetic platform. A claw is fixedly connected to the output shaft end of the first electric push rod. An ultraviolet lamp is adsorbed and fixedly connected to the magnetic platform. A hinge rod is provided on the top of the ultraviolet lamp. The hinge rod is hinged to the claw. The first electric push rod is connected to the display controller signal.

[0021] The beneficial effects of the basic solution are: 1. The first electric push rod is connected to the display controller, allowing for flexible adjustment of the magnetic platform's tilt angle based on the shape of the dispensing equipment and disinfection requirements. Combined with the horizontal rotation of the first and second toothed rings and the vertical lifting motion of the lifting chain, the disinfection component can achieve all-round, multi-angle adjustment in three-dimensional space, ensuring that the UV lamp's disinfection light can accurately cover every corner of the dispensing equipment, including hard-to-reach areas such as edges and grooves, effectively reducing blind spots and improving the comprehensiveness and thoroughness of the disinfection effect.

[0022] 2. The display controller, through precise control of the first electric push rod and with the guidance of the three-dimensional model construction module and the disinfection parameter matching module, enables the disinfection component to accurately locate the key position to be disinfected based on the three-dimensional model of the dispensing equipment, thereby achieving precise disinfection.

[0023] Furthermore, a lifting block is fixedly connected to the outside of the lifting chain located on the second toothed ring. A telescopic rod is hinged to one side of the lifting block. A telescopic motor is fixedly connected to the end of the telescopic rod near the lifting block. A first lead screw is fixedly connected to the output shaft of the telescopic motor. A first ball nut is threaded onto the first lead screw. A push cylinder is fixedly connected to the first ball nut. The push cylinder is fixedly connected to the end of the telescopic rod.

[0024] A second electric push rod is fixedly connected to the top wall of the lifting block. The end of the output shaft of the second electric push rod is hinged to the telescopic rod. A steering motor is fixedly connected to the end of the telescopic rod away from the second electric push rod. A steering platform is fixedly connected to the output shaft of the steering motor. A spraying component is fixedly connected to the steering platform. The telescopic motor, the second electric push rod, and the steering motor are all connected to the display controller signal.

[0025] The beneficial effects of the basic solution are: 1. By driving the first lead screw with a telescopic motor, in conjunction with the first ball nut and push cylinder, the telescopic rod achieves precise telescopic movement along its axial direction; the second electric push rod can drive the entire telescopic rod to perform a wide range of reciprocating telescopic movements; and the steering motor enables the steering platform to rotate in all directions. These combined movements allow the spray nozzle to overcome the limitations of traditional fixed nozzles, acting like a flexible robotic arm to easily reach every corner of the dispensing equipment. Whether it's a deep groove or a tiny gap, it can precisely cover it, effectively eliminating blind spots in disinfection and improving the comprehensiveness and thoroughness of disinfection.

[0026] 2. Under the control of the display controller, the spray nozzle works in perfect harmony with the ultraviolet lamp to form a combination of chemical and physical disinfection. The chemical disinfectant can quickly cover the surface of the instrument and penetrate to the smallest details, complementing the bactericidal effect of the ultraviolet lamp to jointly build a comprehensive and deep disinfection defense, significantly enhancing the disinfection effect and providing a more reliable aseptic guarantee for medical care.

[0027] Furthermore, the spraying component includes a spray cylinder, the bottom end of which is magnetically fixed to the steering platform, and a nozzle is slidably sleeved at the other end of the spray cylinder. A spray chamber is fixedly connected to the inner wall of the spray cylinder, and a liquid spraying layer is opened inside the nozzle. The liquid spraying layer is slidably sleeved and connected to the spray chamber. Several spray holes are opened on the outer walls of both the spray cylinder and the nozzle.

[0028] A telescopic cylinder is fixedly connected to the center of the inner top wall of the nozzle. A second ball nut is fixedly connected to the bottom of the telescopic cylinder. A second lead screw is fitted inside the second ball nut. A spray motor is fixedly connected to the inner bottom wall of the spray nozzle. The output shaft of the spray motor is coaxially and fixedly connected to the second lead screw. A reversing ring is connected to the bottom wall of the spray chamber. The center of the reversing ring is slidably engaged with the output shaft of the spray motor. A damping reversing plate is rotatably connected to the output shaft of the spray motor. The damping reversing plate is slidably engaged with the inner wall of the reversing ring. A disinfection tube and a neutralization tube are symmetrically connected to the bottom wall of the reversing ring. The movement trajectory of the disinfection tube and the neutralization tube coincides with that of the reversing plate. The spray motor is connected to the display controller.

[0029] The beneficial effects of the basic design are: 1. The sliding sleeve structure of the spray nozzle and the spray tank, combined with the interconnected design of the spray layer and the spray chamber, allows the spray nozzle to move flexibly in the axial direction, making it particularly suitable for disinfection inside equipment. Simultaneously, the multiple spray holes on the outer walls of the spray nozzle and spray tank enable multi-point, wide-coverage spraying, ensuring that the disinfectant or neutralizing solution is evenly covered on the surface of the dispensing equipment, including hard-to-reach details, achieving efficient and comprehensive disinfection and cleaning, and improving disinfection effectiveness and efficiency.

[0030] 2. The second lead screw is driven by the spray motor, which in turn drives the damping commutator to rotate within the commutator ring, achieving precise switching between the disinfection tube and the neutralization tube. This design ensures that during disinfection and neutralization, the liquid can be accurately sprayed from the corresponding nozzle according to the preset program and requirements, and the switching of the spray liquid is achieved through a single power source.

[0031] Furthermore, a disinfectant tank and a neutralizing liquid tank are fixedly connected to the top wall of the disinfection box. Both the disinfectant tank and the neutralizing liquid tank are connected to delivery pipes via a liquid pump. A double-layer slip ring is slidably fitted on the top wall of the disinfection box. The delivery pipes are connected to the double-layer slip rings respectively. Each double-layer slip ring has a guide groove inside. A folded pipe is connected to the bottom wall of each double-layer slip ring. The other end of the folded pipe is connected to the disinfection pipe and the neutralizing pipe respectively. The liquid pump is connected to the display controller signal.

[0032] The beneficial effects of the basic design are: 1. The guide groove design inside the double-layer slip ring and the flexible connection of the folded tube allow disinfectant and neutralizing solution to be sprayed through the same set of spray nozzles. When it is necessary to switch liquid types, a quick switch can be achieved simply by adjusting the operation of the liquid pump and the reversing operation of the spray motor through the display controller. This not only reduces the number of nozzles and simplifies the device structure, but also improves work efficiency and avoids interruptions caused by nozzle replacement.

[0033] 2. The double-layer slip ring slides into the top wall of the disinfection box, and the flexible connection of the folded tube allows the liquid delivery system to adapt to the multi-angle and multi-position movement of the spray nozzle in space. Regardless of the angle or position of the spray nozzle, a stable liquid supply is guaranteed, and liquid delivery will not be affected by pipe entanglement or pulling.

[0034] 3. By using a shared nozzle and a single delivery pipeline system, the number of components and complexity of the device are reduced. Compared to equipping the disinfectant and neutralizing solution with separate nozzles and pipelines, this design reduces production costs and maintenance difficulty. At the same time, it also reduces potential points of failure due to multiple nozzles and complex pipelines, improving the reliability and availability of the device.

[0035] Furthermore, the residual cleaning component includes a collection cylinder, which is fixedly connected to the bottom wall of the disinfection box. A barrier net is laid on the top of the collection cylinder, and several vertically upward limiting rods are fixedly connected to the barrier net. A collection pipe is connected to the bottom of the collection cylinder, and a collection cylinder is connected to the end of the collection pipe. Hot air pipes are symmetrically connected to the side wall of the collection pipe. A hot air blower is fixedly connected inside the disinfection box, and all the hot air pipes are connected to the output end of the hot air blower. A filter membrane is laid on the output end of the hot air blower, and the hot air blower is connected to the display controller.

[0036] The beneficial effects of the basic design are: 1. The collection cylinder is located on the bottom wall of the sterilization chamber. Its top baffle effectively prevents sterilized dispensing instruments from falling directly, while allowing disinfectant and water to flow smoothly into the collection cylinder. The vertically upward-pointing limit bar restricts smaller dispensing instruments, preventing them from rolling during sterilization and ensuring all disinfection waste is collected uniformly. This effectively avoids re-contact between sterilized instruments and residual disinfectant, preventing cross-contamination and ensuring the hygiene and safety of medical procedures.

[0037] 2. The hot air blower delivers hot air into the collection pipe through a hot air duct, accelerating the evaporation of moisture from the surface of the sterilized instruments. This is crucial for the rapid drying of medication preparation equipment, especially when it needs to be used quickly in the next stage. Dry equipment prevents drug dilution or reactions caused by residual moisture, ensuring the accuracy of medication and therapeutic efficacy.

[0038] Furthermore, the top side wall of the disinfection box has a ventilation slot, and there are several ventilation holes connecting the ventilation slot to the inner wall of the disinfection box. A fan is installed in the ventilation slot, and an adsorption layer is fixedly connected between the ventilation slot and the outside. The fan is connected to the display controller signal.

[0039] The beneficial effects of the basic solution are: when the disinfection box is working, it will generate ozone, water vapor and harmful gases. The fan in the ventilation slot runs to exhaust the internal air. The adsorption layer filters the bacteria, ozone and other harmful substances in the exhaust gas before it is discharged, purifying the air, keeping the environment inside the box fresh, and avoiding odors from affecting the medical environment and the health of personnel.

[0040] Furthermore, several lidar, cameras, and ultrasonic sensors are fixedly connected to the top wall inside the disinfection box, and all lidar, cameras, and ultrasonic sensors are connected to the display controller.

[0041] The beneficial effects of the basic solution are: multi-dimensional data fusion from lidar, cameras, and ultrasonic sensors generates a high-precision 3D model of the interior of the disinfection box and the dispensing equipment, providing a reliable basis for the display controller to plan the disinfection scheme. Lidar provides precise ranging, cameras provide visual texture, and ultrasonic sensors measure distance and assist in obstacle avoidance. The fused 3D model comprehensively presents the shape, position, and posture details of the equipment, helping to accurately position the disinfection components and achieve efficient and comprehensive disinfection.

[0042] Furthermore, the display controller includes a 3D model building module and a disinfection parameter matching module.

[0043] The 3D model building module is used to fuse laser point cloud data, image information and ultrasonic ranging data to generate a 3D model of the dispensing equipment;

[0044] The disinfection parameter matching module is used to identify the type of dispensing equipment based on the generated 3D model of the dispensing equipment, and adjust the radial angle, height and vertical tilt angle of the disinfection components for disinfection.

[0045] The beneficial effects of the basic solution are as follows: 1. The 3D model construction module integrates laser point cloud data, image information, and ultrasonic ranging data to accurately generate a 3D model of the dispensing equipment, comprehensively presenting the shape, size, and detailed features of the equipment, including complex parts such as grooves and protrusions, providing an accurate basis for subsequent disinfection parameter matching. The disinfection parameter matching module accurately identifies the type of dispensing equipment based on the 3D model and precisely adjusts the radial angle, height, and vertical tilt angle of the disinfection components according to their shape and structural characteristics, ensuring that disinfection can cover every corner of the equipment, achieving precise disinfection, and effectively avoiding the risk of cross-infection due to inadequate disinfection.

[0046] 2. Through precise control of the 3D model construction module and the disinfection parameter matching module, the disinfection components can find the optimal position and angle for disinfection, ensuring the consistency and stability of the disinfection effect. Simultaneously, the display controller can monitor various parameters during the disinfection process in real time and automatically adjust them as needed, further improving the reliability of the disinfection effect and providing a more stable and reliable disinfection guarantee for clinical medical care.

A liquid spray layer is formed inside the nozzle 39, and the liquid spray layer is slidably sleeved and connected to the spray chamber. Several spray holes 40 are formed on the outer walls of both the spray cylinder 37 and the nozzle 39. A telescopic cylinder 41 is welded to the center of the inner top wall of the nozzle 39. A second ball nut 42 is welded to the bottom end of the telescopic cylinder 41, and a second lead screw 43 is fitted inside the second ball nut 42. The inner bottom wall of the spray cylinder 37 is welded with… There is a spray motor 47, the output shaft of which is coaxially welded to the second lead screw 43. A reversing ring 45 is connected to the bottom wall of the spray chamber. The center of the reversing ring 45 is slidably engaged with the output shaft of the spray motor 47. A damping reversing plate 46 is rotatably connected to the output shaft of the spray motor 47. The damping reversing plate 46 is slidably engaged with the inner wall of the reversing ring 45. A disinfection tube 38 and a neutralization tube 44 are symmetrically connected to the bottom wall of the reversing ring 45. The movement trajectory of the disinfection tube 38 and the neutralization tube 44 coincides with that of the reversing plate. The spray motor 47 is connected to the display controller 4.

[0062] The top wall of the disinfection box 1 is fixedly connected to a disinfectant tank 3 and a neutralizing liquid tank 2. Both the disinfectant tank 3 and the neutralizing liquid tank 2 are connected to a delivery pipe 6 via a liquid pump 5. The top wall of the disinfection box 1 is slidably fitted with a double-layer slip ring 17. The delivery pipe 6 is connected to the double-layer slip ring 17.

The other end of the folded pipe 34 is connected to the disinfection pipe 38 and the neutralizing pipe 44 respectively. The liquid pump 5 is connected to the display controller 4.

[0063] The residual cleaning component is used to remove residual disinfectant through drying and reflux collection, and to absorb ozone generated by ultraviolet disinfection to avoid changes in the efficacy of the medicine or the generation of toxic substances. The residual cleaning component includes a collection cylinder 22, which is welded to the bottom wall of the disinfection box 1. A barrier net 23 is laid on the top of the collection cylinder 22, and several vertically upward limiting rods 24 are attached to the barrier net 23. A collection pipe 25 is connected to the bottom of the collection cylinder 22, and a collection cylinder is connected to the end of the collection pipe 25. Hot air pipes 26 are symmetrically connected to the side wall of the collection pipe 25. A hot air fan is installed inside the disinfection box 1. All hot air pipes 26 are connected to the output end of the hot air fan. A filter membrane is laid on the input end of the hot air fan. The hot air fan is connected to the display controller 4.

[0064] The top side wall of the disinfection box 1 has a ventilation slot, and there are several ventilation holes 21 connecting the ventilation slot and the inner wall of the disinfection box 1. A fan is installed in the ventilation slot, and an adsorption layer is bonded between the ventilation slot and the outside. The fan is connected to the display controller 4.

[0065] Several lidar sensors 18, cameras 19 and ultrasonic sensors 20 are attached to the top wall of the disinfection box 1. The lidar sensors 18, cameras 19 and ultrasonic sensors 20 are all connected to the display controller 4.

[0066] The specific implementation process is as follows: Existing disinfection devices are often designed with fixed structures, resulting in large disinfection blind spots or strict limitations on the objects to be disinfected. Furthermore, current disinfection devices tend to overlook residues and byproducts from the disinfection process. These substances can easily adhere to equipment and affect the health and safety of medical staff and patients. This invention aims to overcome the problems of disinfection blind spots and insufficient residue handling in traditional manual disinfection and existing automated disinfection devices when dealing with complex-shaped dispensing equipment.

[0067] When medical staff place the medication preparation equipment into the sterilization chamber 1, the lidar 18, camera 19, and ultrasonic sensor 20 on the top wall of the sterilization chamber 1 immediately work together. The lidar 18 emits a laser beam to scan the outline of the equipment, the camera 19 captures the surface texture, and the ultrasonic sensor 20 measures the height and position of the equipment. This data is simultaneously transmitted to the display controller 4. The 3D model building module within the display controller 4 fuses the laser point cloud data, image information, and ultrasonic ranging data according to existing modeling techniques to generate a 3D model of the equipment. The sterilization parameter matching module then identifies the type of equipment (such as syringes, medication bottles, etc.) based on the model and automatically plans the motion parameters of the sterilization components, such as... Figure 1 and Figure 3 As shown.

[0068] Upon receiving the instruction, the disinfection assembly activates the drive motor 9 inside the disinfection chamber 1. The drive gear 10 on the output shaft of the drive motor 9 meshes with the drive tooth grooves on the inner circumference of the first gear ring 8 and the second gear ring 11, causing the first gear ring 8 and the second gear ring 11 to rotate horizontally within the first and second annular grooves in the bottom wall of the disinfection chamber 1, thus enabling the support bar 14 to achieve a 360° circular motion. Simultaneously, the lifting motor 12 inside the support bar 14 starts, and through the meshing of the lifting gear and the lifting chain 13, it drives the lifting rod to move up and down within the lifting groove, adjusting the vertical height of the ultraviolet lamp 51 and the spray nozzle.

[0069] The ultraviolet lamp 51 located on the first toothed ring 8 has its first electric push rod 54 on the support block 48 extending and retracting according to the command of the display controller 4. This pushes the claw 53 to rotate the magnetic platform 49 around the hinge point, adjusting the tilt angle of the ultraviolet lamp 51. The ultraviolet lamp 51 is attached to the magnetic platform 49 by the platform magnet 50 and can swing flexibly with the magnetic platform 49, ensuring that ultraviolet rays can irradiate the obscured grooves, gaps, and other parts of the appliance. Figure 4 and Figure 6 As shown.

[0070] Located on the second gear ring 11, the second electric push rod 27 on the lifting block 15 pushes the telescopic rod 28 to swing as a whole. The telescopic motor 29 drives the first lead screw 30 to rotate, which drives the telescopic rod 28 to extend and retract axially through the first ball nut 31 and the push cylinder 32. The steering motor 35 drives the steering platform 36 to rotate, allowing the sprayer to adjust its position and direction in all directions. The spray cylinder 37 of the sprayer is magnetically fixed to the steering platform 36. The nozzle 39 can slide and extend and retract on the spray cylinder 37. The spray motor 47 drives the second lead screw 43 to rotate, which causes the nozzle 39 to move axially along the spray cylinder 37 through the second ball nut 42. At the same time, the damping commutator 46 on the output shaft of the spray motor 47 rotates in the commutator ring 45, switching the connection state of the disinfection tube 38 and the neutralization tube 44, realizing the precise switching between disinfectant and neutralizing liquid. The liquids in the disinfectant tank 3 and the neutralizing tank 2, under the action of the liquid pump 5, are discharged through the delivery pipe 6, the guide groove 33 of the double-layer slip ring 17, and the folded pipe 34, and then through the disinfection pipe 38 or the neutralization pipe 44 from the spray nozzle 37 and the spray hole 40 of the nozzle 39. Figure 5 As shown.

[0071] As the nozzle 39 extends, the spray holes 40 that were originally covered on the side wall of the spray cylinder 37 will also be exposed, thereby increasing the spray flow channel of the entire spraying component, making the disinfectant spray more comprehensive. After disinfection, the neutralizing solution (such as sodium thiosulfate solution) is switched to neutralize the harmful components in the chlorine-containing disinfectant, avoiding potential problems in subsequent drug preparation.

[0072] During disinfection, the residual cleaning components work simultaneously. The barrier net 23 at the top of the collection cylinder 22 collects the waste liquid after disinfection, and the limiting rod 24 prevents small utensils from rolling. The waste liquid flows into the collection tank through the collection pipe 25. The hot air fan inside the disinfection chamber 1 starts, and hot air is sent into the collection pipe 25 through the hot air pipe 26 to accelerate the evaporation of moisture from the surface of the utensils. The fan in the ventilation slot on the top side wall of the disinfection chamber 1 operates, driving the air inside the chamber through the adsorption layer to remove ozone and other harmful gases generated by ultraviolet disinfection, such as... Figure 2 As shown.

[0073] Throughout the disinfection process, the display controller 4 monitors the operating status of each component in real time. Based on the three-dimensional model and disinfection parameters, it dynamically adjusts the rotation angle of the first toothed ring 8 and the second toothed ring 11, the pitch angle of the ultraviolet lamp 51, the extension and retraction length of the sprayer and the spray direction to ensure that physical disinfection (ultraviolet light) and chemical disinfection (medicinal spray) work together to cover all surfaces of the equipment. After disinfection is completed, the neutralization liquid spray and drying program are automatically started to realize the fully automated operation of "identification-disinfection-residue treatment".

[0074] Example 2:

[0075] The difference from the above embodiments is that, in conjunction with the appendix Figure 7 As shown: The display controller 4 is equipped with a 3D model construction module and a disinfection parameter matching module.

[0076] The 3D model building module is used to fuse laser point cloud data, image information and ultrasonic ranging data to generate a 3D model of the dispensing equipment;

[0077] The disinfection parameter matching module is used to identify the type of dispensing equipment based on the generated 3D model of the dispensing equipment, and adjust the radial angle, height and vertical tilt angle of the disinfection components for disinfection.

[0078] The specific implementation process is as follows: The 3D model construction module first receives data from LiDAR 18, camera 19, and ultrasonic sensor 20, and performs multi-source data fusion on this data.

[0097] Experimental group: The device of the present invention.

[0098] 3. Test Indicators and Methods

[0100] Microbial kill rate: Colony count method (CFU), calculation formula:

[0101]

[0102] Chloride ion residue: Ion chromatography (GB / T 5750.5).

[0103] Ozone Residue: Portable ozone detector (5mm from the surface).

[0104] Operational efficiency: The timer records the entire process, and the operator scores the results (1 point = fully automatic, 5 points = frequent manual intervention).

[0105] 4. Experimental Procedure

[0106] (1) Disinfection blind spot test

[0107] All equipment surfaces were coated with photosensitive fluorescent dye. The control group was irradiated with a fixed UV lamp for 60 seconds; the experimental group underwent dynamic UV + 0.1% chlorine disinfectant spraying (10 seconds). The fluorescent residual areas were photographed under UV light, and the percentage of uncovered area was calculated.

[0108] (2) Microbial killing effect

[0109] Wipe key areas of instruments (such as the neck of ampoules) with sterile cotton swabs, immerse in PBS buffer, spread on TSA plates and incubate for 24 hours (37°C), count CFU and calculate the kill rate.

[0110] (3) Disinfection residue detection

[0111] The surface of the utensils was rinsed with ultrapure water, and the chloride ion concentration was determined by ion chromatography; the surface ozone concentration was detected immediately after disinfection.

[0112] (4) Operational efficiency test

[0123] 6. Experimental Conclusions

[0124] The device of this invention achieves a coverage rate of 98.6% for ampoules (compared to only 68.5% for the control group). The key improvement lies in the dynamic ultraviolet lamp irradiating the inner wall of the bottle neck at a 60° angle, allowing the spray liquid to penetrate the marked indentation on the bottle body (depth ≤ 0.2 mm).

[0125] The coverage of the syringe plunger groove increased to 99.5% (compared to 83.2% in the control group), demonstrating that the multi-degree-of-freedom robotic arm effectively eliminated the shadowed area.

[0126] The experimental group achieved a 99.991% kill rate against Bacillus subtilis in the ampoules (compared to 80.1% in the control group), meeting medical sterilization standards (>99.99%). Ultraviolet light disrupts DNA structure, while chlorine-containing disinfectant oxidizes the cell wall, achieving dual inactivation of drug-resistant bacteria.

[0127] The residual chloride ion in the experimental group was only 0.4 ppm (compared to 35.7 ppm in the control group), thanks to the closed-loop scavenging chain formed by the neutralization solution spraying and negative pressure adsorption (-90 kPa). The ozone concentration was reduced to 0.03 ppm (one-third of the OSHA limit), avoiding the risk of drug oxidation and denaturation.

[0128] The experimental group had a 20-second longer disinfection time per cycle, but the fully automated process significantly reduced human intervention (complexity score decreased by 58.5%) and simultaneously completed disinfection, neutralization and drying.
