Description

Technical Field

[0001] This invention relates to the field of infusion container disinfection, and in particular to an infusion container disinfection device. Background Technology

[0002] Intravenous infusion therapy is a common and effective treatment method in clinical practice and is widely used in the treatment of various diseases. Currently, common intravenous infusion therapy generally requires nurses to perform the operation. When there are many patients, nurses often cannot change the infusion container for patients in a timely manner.

[0003] To address the aforementioned issues, automated infusion devices have emerged in recent years. These devices can secure the puncture sites of multiple infusion containers (infusion bags or bottles) after they are suspended, and automatically insert and remove the puncture needles. When it is necessary to change the infusion container, switching is achieved through structures such as turntables or conveyor belts. Although these automated infusion devices have improved the efficiency of changing infusion containers to some extent and greatly reduced situations where nurses cannot change infusion containers for patients in a timely manner, certain limitations still exist.

[0004] For example, in order to adapt to the automatic insertion of puncture needles during the automatic rotation of multiple bags, the protective cap of the infusion container needs to be opened in advance. This inevitably leads to contamination of the bottle opening due to the long waiting time. Therefore, it is necessary to solve the problem of timely disinfection of the infusion container bottle opening. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an infusion container disinfection device with the advantage of automatic disinfection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An infusion container sterilization device, comprising: The feeding station has a carrier box for providing disinfection carriers; The disinfection station uses the disinfection carrier to disinfect the head of the infusion container. A recycling station for recycling the used disinfectant carrier; and... A carrier transfer mechanism is used to transfer the disinfection carrier to achieve disinfection of the infusion container and recovery of the disinfection carrier.

[0007] By adopting the above technical solution, the carrier box at the feeding station can continuously provide the device with disinfection carriers, while the carrier transfer mechanism undertakes the transfer of disinfection carriers between various stations. It transfers the disinfection carriers from the feeding station to the disinfection station. After the disinfection station performs disinfection on the head of the infusion container, the carrier transfer mechanism transfers the used disinfection carriers to the recycling station for recycling. The entire process realizes full automation of the automatic supply, transfer, disinfection operation, and recycling of disinfection carriers. There is no need for manual intervention in the handling and disposal of disinfection carriers, thus achieving the effect of automatic disinfection. This effectively avoids the pollution that may be caused by manual operation and also improves the efficiency and reliability of infusion container disinfection.

[0008] Optionally, the carrier transfer mechanism includes a carrier driving component and a transfer driving component; the transfer driving component is used to drive the carrier driving component to move; the carrier driving component has a placement part and a pushing part; the placement part is used to place the disinfection carrier; the pushing part is used to drive the disinfection carrier to detach from the carrier box.

[0009] By adopting the above technical solution, the carrier drive component achieves stable support of the disinfection carrier through the placement part, ensuring that the carrier will not shift or fall during the transfer process. The pushing part is specifically responsible for pushing the carrier out of the carrier box. The two work together to enable the carrier to smoothly enter the transfer process from the feeding station. As a power source, the transfer drive component drives the carrier drive component to move between each station according to a preset path. Its driving accuracy directly affects the positioning accuracy of the carrier at each station, thus determining the precision of the disinfection operation and the overall operational stability of the device. When the carrier drive component passes the feeding station, the pushing part, through cooperation with the discharge notch and other structures of the carrier box, pushes out the disinfection carrier located at the bottom of the carrier box, so that it falls precisely onto the placement part, completing the carrier picking action. In addition, during the movement of the carrier drive component, the pushing part can play a certain limiting role for the disinfection carrier, which helps to improve the positional stability of the disinfection carrier.

[0010] Optionally, the carrier box includes a carrier box body; a plurality of the disinfection carriers are disposed in the carrier box body; the carrier box body has an opening facing downward and a discharge notch is provided at the lower end of its side wall; the discharge notch is for the pusher to pass through to push out the disinfection carriers.

[0011] By adopting the above technical solution, the downward-facing design of the carrier box body allows the internal disinfection carriers to move naturally downwards under their own gravity, providing a power basis for continuous feeding. The discharge notch at the lower end of the side wall provides a precise channel for the pushing part to push out the disinfection carriers. When the pushing part of the carrier transfer mechanism moves to the feeding station, it can penetrate into the carrier box body through the discharge notch, contact the bottommost disinfection carrier, and apply a pushing force, thus smoothly pushing it out of the carrier box body onto the placement part. The size and position of the discharge notch are precisely designed to ensure that the pushing part can pass smoothly and effectively act on the disinfection carrier, while also providing lateral restraint for other unpushed disinfection carriers, preventing multiple carriers from falling together or shifting positions during the pushing process. This ensures that only one disinfection carrier is pushed out at a time, achieving orderly and accurate carrier supply. At the same time, this structural design simplifies the cooperation between the carrier box and the carrier transfer mechanism, reduces the complexity of the device, and improves the overall operational reliability.

[0012] Optionally, the placement part is a turntable; the pushing part is a first transfer pushing component disposed on the turntable; and the transfer drive assembly drives the turntable to rotate.

[0013] By adopting the above technical solution, the circumferential distribution characteristics of the turntable allow each station to be evenly arranged around it, optimizing the spatial layout of the device and making the overall structure more compact. The first transfer pusher is mounted on the turntable and rotates synchronously with it. When the turntable drives the first transfer pusher to the feeding station, it precisely pushes the disinfection carrier out of the carrier box through the discharge notch and onto the corresponding position on the turntable. The transfer drive assembly drives the turntable's rotation. By controlling the turntable's rotation angle and speed, the dwell time of the carrier at each station can be precisely controlled, ensuring that processes such as liquid immersion, disinfection, and recycling are fully performed. Furthermore, the turntable's rotational stability is good, reducing carrier swaying during transfer and ensuring the stability of the disinfection carrier's position on the placement section, thus guaranteeing the accuracy of subsequent disinfection operations. The integrated design of the first transfer pusher and the turntable allows the pushing and transfer actions to be synchronized and coordinated, simplifying the transmission structure, reducing control difficulty, and further improving the reliability and stability of the device operation.

[0014] Optionally, the turntable is provided with a coaxially arranged upper convex ring; the upper convex ring passes through the discharge notch; the first transfer pusher is disposed on the upper end face of the upper convex ring.

[0015] By adopting the above technical solution, the design of the upper convex ring passing through the discharge notch allows the ring to extend into the carrier box body to a certain depth during the rotation of the turntable, providing stable support and positioning reference for the contact between the first transfer pusher and the disinfection carrier. The first transfer pusher is located on the upper end face of the upper convex ring, and its height matches the lowest disinfection carrier inside the carrier box, ensuring that the pusher can accurately contact the edge of the disinfection carrier and apply pushing force. This structural design makes the pushing action more direct and stable, effectively overcoming any friction or slight adhesion between disinfection carriers, ensuring that each push successfully pushes out a single disinfection carrier. At the same time, the upper convex ring also increases the structural strength of the turntable when carrying the disinfection carrier, preventing the turntable from deforming due to excessive local stress and improving the overall service life of the device.

[0016] Optionally, the feeding station has a blocking component; the blocking component is located on the side of the feeding station close to the disinfection station; the blocking component prevents the disinfection carrier from moving together with the turntable; the turntable is provided with a blocking drive component; the blocking drive component is used to drive the blocking component to avoid the disinfection carrier.

[0017] By adopting the above technical solution, at the feeding station, to prevent the bottom disinfectant carrier from being carried out by the friction of the turntable before the transfer pusher arrives, a blocking component located on the side of the feeding station near the liquid supply station effectively blocks the disinfectant carrier. The blocking component limits the movement of the disinfectant carrier in its direction of travel, ensuring that the carrier accurately stops at the feeding station, awaiting the cooperation of the turntable's transfer pusher. When the turntable begins to rotate according to a preset program, preparing to transfer the disinfectant carrier from the feeding station to the next station, the blocking drive component on the turntable begins to operate. The blocking drive component can drive the blocking component to change its position or orientation, such as retracting it below the turntable surface, flipping it upwards, or translating it away from the turntable center, thus making way for the disinfectant carrier. At this time, as the turntable rotates, the transfer pusher can smoothly contact the disinfectant carrier and carry it past the original blocking component, smoothly entering the liquid supply station. This structural design, through the coordinated work of the blocking components and the blocking drive components, ensures the precise positioning of the disinfection carrier at the feeding station and can reliably avoid obstacles when transfer is required, thus ensuring the orderly and accurate transportation of the disinfection carrier between stations.

[0018] Optionally, the blocking member has a blocking part and an avoidance driving part; during the movement of the blocking driving member, the avoidance driving part drives the blocking part to avoid the disinfection carrier.

[0019] By adopting the above technical solution, when the blocking drive component moves with the turntable and comes into contact with the avoidance drive component, it applies a force to the avoidance drive component, thereby causing the blocking component to shift or rotate, thus avoiding the disinfection carrier. For example, the avoidance drive component can be designed as an inclined guide surface. When the blocking drive component (such as a cam or lever located below the turntable) rotates with the turntable and comes into contact with the guide surface, the blocking drive component slides along the guide surface, thereby pushing the avoidance drive component upward or to the side. This causes the blocking component connected to the avoidance drive component to lift upward or swing to one side, no longer obstructing the disinfection carrier. After the blocking drive component passes the avoidance drive component, the blocking component can automatically return to its initial blocking position under the action of a reset mechanism such as a return spring, continuing to limit the subsequent disinfection carrier. This method of switching between blocking and avoidance through mechanical contact transmission is simple and reliable in structure, requires no additional complex control system, and can complete the avoidance action synchronously during the turntable rotation, ensuring the continuity and accuracy of the disinfection carrier transfer.

[0020] Optionally, the mounting part is a rotating arm; the pushing part is a second transfer pushing component disposed on the rotating arm; and the transfer drive assembly drives the rotating arm to rotate.

[0021] By adopting the above technical solution, the design of the rotating arm allows the carrier transfer mechanism to flexibly switch between different workstations by rotation, making it particularly suitable for scenarios where workstations are relatively far apart or scattered, exhibiting strong spatial adaptability. The second transfer pusher is mounted on the rotating arm and rotates with it. When the rotating arm drives the second transfer pusher to the feeding station, the second transfer pusher can precisely dock with the disinfection carrier in the carrier box and push it out of the carrier box through a pushing action. The rotating arm then continues to rotate, transferring the disinfection carrier to the liquid supply station, disinfection station, and recovery station. The transfer drive assembly drives the rotating arm to rotate. By controlling the rotation angle and start / stop timing of the rotating arm, precise delivery and transfer of the disinfection carrier at each workstation can be achieved. The rotating arm structure is relatively simple, with few moving parts, which helps reduce the maintenance cost and failure rate of the device. The combination of the second transfer pusher and the rotating arm allows the pushing action to be completed synchronously during the rotation of the rotating arm, improving transfer efficiency. Meanwhile, the rotation radius of the swing arm can be designed according to the actual workstation layout, allowing for flexible adjustment of the transfer path of the disinfection carrier to meet the needs of disinfection devices for infusion containers of different sizes. In addition, except when the disinfection carrier needs to be transferred, the disinfection carrier and the carrier transfer mechanism (i.e., the swing arm) do not interact when the swing arm rotates, so there is no friction and no need for baffles. For the disinfection carrier, reducing contact with the outside world helps maintain its cleanliness.

[0022] Optionally, the feeding station has a blocking strip; the blocking strip is located directly below the carrier box body to prevent the disinfection carrier from detaching downward from the carrier box body; the rotating arm and the second transfer pusher are provided with blocking strip clearance grooves that cooperate with the blocking strip.

[0023] By adopting the above technical solution, the blocking strip is located directly below the carrier box body, effectively supporting the disinfection carrier inside the carrier box body and preventing it from falling directly from the downward-facing carrier box body under its own weight. This ensures that the disinfection carrier is pushed out only by the action of the second transfer pusher. When the rotating arm moves the second transfer pusher to the feeding station, the blocking strip clearance grooves on the rotating arm and the second transfer pusher correspond to the position of the blocking strip, allowing the blocking strip to pass through the clearance grooves and avoiding interference between the rotating arm and the second transfer pusher and the blocking strip during the material handling process. Specifically, before material handling, the blocking strip supports the lowest disinfection carrier inside the carrier box body; when the second transfer pusher moves to the blocking strip with the rotating arm, the blocking strip clearance groove accommodates the blocking strip. At this time, the second transfer pusher can push the disinfection carrier out of the discharge notch of the carrier box body, and the pushed-out disinfection carrier can land on the bearing surface of the rotating arm and leave the feeding station as the rotating arm rotates. This design ensures that the blocking strip effectively blocks the disinfection carrier while providing the necessary space for the rotating arm and the second transfer pusher to pick up the material, achieving coordinated operation between the two and ensuring that the disinfection carrier can be accurately and smoothly removed from the carrier box and transferred. The shape and size of the blocking strip's clearance groove are adapted to the blocking strip, which not only avoids mechanical interference but also guides and positions the rotating arm to a certain extent, improving the positional accuracy of the rotating arm when picking up material at the feeding station.

[0024] Optionally, a lower limiting member is provided at the bottom of the carrier box body; the lower limiting member prevents the disinfection carrier from detaching downward from the carrier box body.

[0025] By adopting the above technical solution, the limiting component can effectively support and limit the stacked disinfection carriers inside the carrier box. When the opening of the carrier box is facing downwards, the disinfection carriers tend to fall downwards under their own weight and the pressure of the upper counterweight (if installed). The lower limiting component can support the disinfection carriers from below, preventing them from falling off the carrier box body on their own. Only when the pushing part moves to the discharge gap and contacts the bottom disinfection carrier with sufficient pushing force will the disinfection carrier be smoothly brought out from the discharge gap, thereby further ensuring the accuracy and reliability of the disinfection carrier supply and avoiding accidental falling and waste of disinfection carriers. In addition, due to the presence of the lower limiting component, the disinfection carriers will not fall out of the carrier box body during the process of placing the carrier box into the feeding station with the opening facing downwards and taking it out of the feeding station, reducing the possibility of contamination of the disinfection carriers. At the same time, it provides the possibility of recycling unused disinfection carriers, and recycling only requires pulling out the carrier box, which is simple to operate.

[0026] Optionally, the disinfection station has a disinfection drive mechanism, which includes a carrier rotating gripper, a rotation drive assembly, and a lifting drive assembly; the lifting drive assembly is used to drive the carrier rotating gripper to move vertically up and down; the rotation drive assembly is used to drive the carrier rotating gripper to rotate; the placement part has a clearance hole for the carrier rotating gripper to pass through vertically.

[0027] By adopting the above technical solution, when the disinfection carrier is transferred to the disinfection station after being soaked in the supply solution, the clearance hole on the placement part (such as a turntable or rotating arm) provides vertical operating space for the carrier rotating gripper. The lifting drive assembly first drives the carrier rotating gripper to rise vertically, allowing it to pass through the clearance hole and approach the disinfection carrier from below. During the ascent, the carrier rotating gripper pulls the disinfection carrier up together, lifting it off the placement part and detaching it from the placement part, leaving it in a suspended state. At this time, the rotation drive assembly starts working, driving the carrier rotating gripper and the gripped disinfection carrier to rotate together. By controlling the rotation angle and speed of the rotation drive assembly, 360-degree omnidirectional rotation of the disinfection carrier can be achieved, ensuring that the disinfectant soaked on the disinfection carrier can be evenly applied to or act on the surface of the infusion container to be disinfected, avoiding disinfection dead zones. After disinfection, the lifting drive assembly drives the carrier rotating gripper to descend, placing the disinfection carrier back into the placement part, completing the disinfection operation. This structural design, through a combination of lifting and rotation, not only achieves full contact and relative movement between the disinfection carrier and the infusion container, improving the uniformity and thoroughness of the disinfection effect, but also allows for independent drive control of the carrier's rotating gripper. This enables flexible adjustment of disinfection parameters (such as rotation speed, rotation time, and lifting height) according to the disinfection needs of different infusion containers, enhancing the versatility of the device and the controllability of the disinfection process. The avoidance holes cleverly solve the spatial interference problem between the rotating gripper and the placement part, ensuring the coordination and smoothness of the movements of each mechanism.

[0028] Optionally, the carrier rotating gripper has a central abutment and a plurality of driving claws; the central abutment is coaxially arranged with the rotation center axis of the carrier rotating gripper; all the driving claws are evenly distributed around the circumference of the central abutment; the central abutment is higher than the driving claws.

[0029] By adopting the above technical solution, when the carrier rotating gripper rises and lifts the disinfection carrier, the central abutment part first contacts the central area of ​​the disinfection carrier and applies an upward force to it. Since the central abutment part is higher than the driving claw, as the central abutment part lifts the disinfection carrier upward, the edge of the disinfection carrier naturally droops and covers the driving claw. At this time, the driving claw can stably support the edge of the disinfection carrier from below. This structural design ensures that the disinfection carrier maintains a stable posture during lifting and rotating wiping, preventing displacement or detachment. The central abutment part precisely abuts against the center of the infusion container head, providing a stable support point for the disinfection carrier, while several evenly distributed circumferential driving claws support the disinfection carrier from all sides, ensuring that the disinfection carrier can evenly contact the outer surface of the infusion container head during rotating wiping, thus guaranteeing the uniformity and comprehensiveness of wiping and avoiding disinfection dead zones caused by uneven force or positional displacement of the disinfection carrier.

[0030] Optionally, the recycling station has a squeezing block and a recycling bin; the recycling bin is lower than the placement part; the squeezing block has a squeezing surface; the squeezing surface blocks and guides the disinfection carrier away from the placement part and into the recycling bin; the squeezing block avoids the pushing part.

[0031] By adopting the above technical solution, when the used disinfectant carrier placement unit moves to the recycling station, the squeezing block on the outside of the turntable will obstruct the disinfectant carrier. As the placement unit continues to move, the squeezing surface will apply a force pointing outwards to the disinfectant carrier. Since the recycling bin is located outside the placement unit and its height is lower than the placement unit, under the combined action of the squeezing surface and the inertia of the disinfectant carrier itself, the used disinfectant carrier will gradually detach from the support of the placement unit and slide down along the squeezing surface into the recycling bin below, completing the recycling. At the same time, the squeezing block is deliberately designed to avoid the pushing part on the placement unit, so that when the pushing part moves with the placement unit through the recycling station, it can pass smoothly through the squeezing block without interfering with it, ensuring the continuous and stable movement of the placement unit and the normal working cycle of the pushing part. This structural design realizes automated, contactless recycling of the used disinfectant carrier, avoids secondary pollution that may be caused by manual recycling, and also ensures the smooth operation of the entire device.

[0032] Optionally, the extrusion block is higher than the pushing part; the distance between the lower end faces of the extrusion block and the pushing part is less than the thickness of the disinfection carrier.

[0033] By adopting the above technical solution, the design of the extrusion block being higher than the pusher section ensures that the extrusion surface of the extrusion block mainly acts on the upper surface or middle area of ​​the disinfection carrier, without direct structural interference with the pusher section. Simultaneously, the distance between the lower end faces of the extrusion block and the pusher section is less than the thickness of the disinfection carrier—a crucial design feature. When the used disinfection carrier moves to the recycling station along with the placement and pusher sections, because the thickness of the disinfection carrier is greater than the distance between the lower end faces of the extrusion block and the pusher section, the edge of the disinfection carrier is blocked by the extrusion surface of the extrusion block. At this time, the pusher section and placement section continue to move forward, and the disinfection carrier, under the combined action of the blocking force of the extrusion surface and the pressure of the pusher section, will undergo a certain degree of bending or deformation, ultimately being forcibly squeezed out from the gap between the pusher section and the extrusion block onto the surface of the placement section, and falling into the recycling bin under gravity. This design ensures that even if the disinfection carrier becomes soft or partially adheres to the pusher section after use, it can still be reliably peeled off from the placement section and recycled, preventing used disinfection carrier residue from remaining on the placement section and affecting the subsequent transfer of disinfection carriers and the normal operation of the entire device.

[0034] Optionally, the extrusion block has a horizontal clearance groove through which the pusher passes; the horizontal clearance groove is configured such that the sterilization carrier cannot pass through.

[0035] By adopting the above technical solution, the horizontal clearance trough provides a dedicated passage for the pushing part. When the pushing part moves to the recycling station with the placement part, it can accurately pass through the horizontal clearance trough, avoiding direct collision with the extrusion block and ensuring the continuity and smoothness of the pushing part's movement. Simultaneously, the dimensions of the horizontal clearance trough are strictly designed; its width and height only allow the pushing part to pass through, while the disinfection carrier, due to its thickness or size exceeding the clearance of the horizontal clearance trough, cannot pass through. Thus, when the disinfection carrier moves to the recycling station with the placement part, the extrusion surface of the extrusion block effectively blocks it, while the pushing part continues to move unimpeded. Under the relative motion between the pushing part and the extrusion surface, the disinfection carrier is reliably scraped off the placement part and guided into the recycling bin. This structural design cleverly solves the interference problem between the pushing part and the extrusion block, while ensuring effective blocking and recycling of the disinfection carrier, further improving the stability and reliability of the recycling process and preventing the disinfection carrier from leaking through the clearance trough due to the pushing part's passage.

[0036] Optionally, the pushing part includes several pushing component blocks; the horizontal clearance groove includes several clearance grooves that correspond one-to-one with the pushing component blocks.

[0037] By adopting the above technical solution, when the pushing section is composed of several pushing component blocks, the horizontal clearance groove is correspondingly designed as several clearance grooves that correspond one-to-one with each pushing component block. This structure enables a more precise fit between the pushing section and the extrusion block. Each pushing component block can independently pass through its corresponding clearance groove when it moves to the recycling station with the placement section, ensuring that the entire pushing section can smoothly pass through the extrusion block and avoiding localized interference with the extrusion block due to the presence of the pushing component blocks. Furthermore, since the clearance grooves correspond one-to-one with the pushing component blocks, the size of each clearance groove can be individually designed according to the specific shape and size of the corresponding pushing component block, further optimizing the clearance effect and ensuring the smooth movement of the pushing component blocks. Even if the disinfection carrier partially covers the gap between the pusher sections during its movement, the extrusion block between the avoidance slots can still effectively block the disinfection carrier. Furthermore, since the size of each avoidance slot is small, the disinfection carrier cannot pass through any of them. This ensures that while the pusher passes smoothly, the disinfection carrier can be reliably blocked and guided into the recycling bin, further improving the adaptability and reliability of the recycling mechanism.

[0038] Optionally, the carrier box includes a carrier box body, a counterweight, and several disinfection carriers stacked vertically; the counterweight and the several disinfection carriers are located inside the carrier box body; the counterweight is located on the upper side of all the disinfection carriers; and the lower end of the carrier box body is open.

[0039] By adopting the above technical solution, the design of the opening at the bottom of the carrier box body allows the bottommost disinfection carrier to be smoothly pushed out of the opening under the action of the counterweight. The counterweight is located on top of all the disinfection carriers, and its own weight will generate a continuous and stable downward pressure on the disinfection carriers below. This structural design uses the gravity of the counterweight as an auxiliary driving force, simplifying the driving complexity of the feeding mechanism while ensuring the continuity and stability of the disinfection carrier supply. In addition, the setting of the counterweight also ensures that the disinfection carriers inside the carrier box can always maintain a compact stacked state during placement and removal, reducing the risk of misalignment or tipping of the disinfection carriers due to shaking, and further ensuring the accuracy of feeding.

[0040] Optionally, the carrier box body is made transparent to allow observation of the remaining amount of disinfectant carrier in the carrier box, and / or The feeding station has a carrier monitoring component to monitor the remaining amount of sterilized carrier in the carrier box.

[0041] By adopting the above technical solution, the transparent design of the carrier box allows staff to directly observe the remaining quantity of disinfectant carriers inside. This eliminates the need to open the carrier box, enabling them to monitor the consumables' remaining quantity at any time, facilitating timely replenishment and preventing disruptions to the disinfection process due to carrier depletion. Simultaneously, the carrier monitoring component at the supply station can automatically and accurately monitor the remaining quantity of disinfectant carriers within the carrier box. For example, the carrier monitoring component can use photoelectric sensors or image recognition technology to detect the height or quantity of disinfectant carriers at the top layer or specific locations within the carrier box in real time. When the monitored quantity falls below a preset threshold, the carrier monitoring component can automatically issue an early warning signal, reminding staff to replace or replenish the carrier box promptly, further enhancing the intelligence level of the device's operation and the convenience of maintenance. The combination of the transparent carrier box and the carrier monitoring component forms a dual-protection mechanism, enabling both visual judgment and precise early warning through automated monitoring, ensuring the reliability of disinfectant carrier supply and effectively preventing carrier shortages caused by human negligence.

[0042] Optionally, when the carrier box body is transparent, the counterweight has a set color; the set color is different from the color of the disinfection carrier; the carrier monitoring component is a color mark sensor; the color mark sensor is used to detect the counterweight with the set color.

[0043] By adopting the above technical solution, when the carrier box body is transparent and the counterweight has a different set color from the disinfection carrier, a color mark sensor as the carrier monitoring component can accurately detect the remaining amount of disinfection carrier. The color mark sensor is highly sensitive to specific colors. As the disinfection carrier in the carrier box gradually decreases, the counterweight will gradually descend with the consumption of disinfection carrier. Because the set color of the counterweight is significantly different from that of the disinfection carrier, when the remaining amount of disinfection carrier drops to a preset warning value, the counterweight will descend into the detection area of ​​the color mark sensor. At this time, the color mark sensor can accurately identify the counterweight with the set color and immediately trigger a signal indicating insufficient remaining amount. This design utilizes color difference as a detection indicator, avoiding misjudgments caused by slight changes in the color of the disinfection carrier itself or interference from impurities, greatly improving the accuracy and reliability of remaining amount monitoring. Simultaneously, combined with the transparent carrier box body, staff can also observe the position of the counterweight to assist in judging the remaining amount. The automatic detection of the color mark sensor and manual observation complement each other, further ensuring effective monitoring of the remaining amount of disinfection carrier, timely reminders for replenishment, and ensuring the continuous operation of disinfection work.

[0044] Optionally, when the carrier box body is transparent, at least one "remaining quantity" character is provided on the outer surface of the carrier box body; the remaining quantity character corresponds to the uppermost disinfection carrier to determine the remaining amount of disinfection carrier inside the carrier box body.

[0045] By adopting the above technical solution, when the carrier box body is transparent, remaining quantity characters are set on its outer surface. These characters correspond to the position of the topmost disinfectant carrier, providing staff with an intuitive and convenient way to determine the remaining quantity. For example, the remaining quantity characters can be designed as scale lines combined with numbers (such as "100%", "75%", "50%", "25%", "0" or "10", "8", "6", "4", "2", "0") or simple markings such as "full", "medium", and "low". When the carrier box is full of disinfectant carrier, the upper surface of the topmost disinfectant carrier will align with the remaining quantity characters (such as "100%" or "full") at a higher position. As the disinfectant carrier is continuously consumed, the position of the topmost disinfectant carrier gradually moves down, aligning with remaining quantity characters at different heights. Staff can observe which remaining quantity character the topmost disinfectant carrier corresponds to through the transparent carrier box body, thus quickly determining the approximate quantity or proportion of remaining disinfectant carrier in the box. This design eliminates the need for complex electronic sensors, allowing for preliminary assessment of remaining supplies solely through visual observation. It is simple and intuitive to operate, and serves as an effective auxiliary means of assessment, especially when the carrier monitoring component experiences temporary malfunctions or requires rapid confirmation. This further enhances the convenience and reliability of the carrier box, ensuring that staff can promptly understand the status of consumables and replenish them.

[0046] Optionally, the counterweight is made of metal, the carrier monitoring component is a metal sensor, and the carrier box body is made of non-metallic material.

[0047] By adopting the above technical solution, when the counterweight is made of metal and the carrier box body is made of non-metallic material, the metal sensor can effectively penetrate the non-metallic carrier box body to accurately detect the internal metal counterweight. As the disinfection carrier in the carrier box is continuously consumed, the metal counterweight will gradually move downwards. When the remaining amount of disinfection carrier decreases to a preset threshold, the metal counterweight will move into the detection range of the metal sensor. The metal sensor accurately determines the insufficient amount of disinfection carrier by sensing the signal change generated by the metal material. This design utilizes the different response characteristics of metal and non-metallic materials to sensor signals, ensuring the stability and accuracy of the detection. The non-metallic carrier box body does not interfere with the detection signal of the metal sensor, enabling the sensor to reliably identify the positional changes of the counterweight. At the same time, the metal counterweight has high density and structural stability, and its own gravity can stably act on the disinfection carrier below, ensuring a smooth feeding process. The metal sensor provides a simple, low-cost, and highly anti-interference solution for remaining amount monitoring, further improving the reliability of carrier monitoring and the overall economy of the device.

[0048] Optionally, a disinfection carrier detection sensor may also be included; the disinfection carrier detection sensor is used to detect whether the carrier transfer mechanism obtains the disinfection carrier from the feeding station.

[0049] By adopting the above technical solution, the disinfectant carrier detection sensor enables real-time monitoring and verification of the carrier transfer mechanism's material handling actions. When the carrier transfer mechanism attempts to acquire the disinfectant carrier from the feeding station, the sensor immediately detects whether the carrier has been successfully acquired. If the system detects that the carrier transfer mechanism has failed to acquire the disinfectant carrier, it immediately issues an alarm and suspends the subsequent disinfection process. This prevents incomplete disinfection of the infusion container due to idling or ineffective operations, and simultaneously reminds staff to check if the carrier box at the feeding station is empty, if the disinfectant carrier is stuck, or if the transfer mechanism is malfunctioning. This design effectively prevents disinfection omissions caused by material handling failures, ensuring that every infusion container receives effective disinfection treatment, further improving the reliability and safety of the entire disinfection device, and preventing the outflow of substandard disinfectant products.

[0050] Optionally, it also includes a liquid supply station; the liquid supply station is used to provide liquid disinfectant to the disinfection carrier to wet the disinfection carrier.

[0051] By adopting the above technical solution, the liquid supply station is designed to provide disinfection carriers that have not absorbed liquid disinfectant. This makes them easier to store and transport compared to carriers that have absorbed liquid disinfectant. Once the carrier transfer mechanism moves the disinfection carrier from the material supply station to the liquid supply station, the liquid supply station supplies liquid disinfectant to the carrier according to a preset dosage and method. For example, the liquid supply station can be equipped with a nozzle, drip tube, or immersion tank to ensure that the liquid disinfectant evenly covers the surface of the disinfection carrier or penetrates its internal pores. This design ensures that the disinfection carrier has fully absorbed and maintained a sufficient concentration of disinfectant before contacting the infusion container, thereby effectively killing bacteria, viruses, and other microorganisms on the surface of the infusion container during the disinfection process.

[0052] Optionally, it may also include a sterilization component for sterilizing the area where the carrier transfer mechanism comes into contact with the disinfection carrier.

[0053] By adopting the above technical solution, the sterilization component installed at the infusion station can specifically disinfect the contact area between the carrier transfer mechanism and the disinfection carrier, effectively preventing the growth of bacteria or residual contaminants at this contact point during multiple carrier transfers, thus preventing cross-contamination of subsequent disinfection carriers. For example, when the pushing or adsorption component of the carrier transfer mechanism removes the disinfection carrier from the carrier box, its contact surface may be contaminated with a small amount of microorganisms from inside the carrier box or the environment. Without disinfection, these microorganisms may adhere to the surface when transferring new disinfection carriers, affecting the cleanliness and disinfection effect of the disinfection carrier. The sterilization component can use ultraviolet irradiation, ozone disinfection, or chemical disinfection spray to quickly and efficiently disinfect the contact area before the carrier transfer mechanism completes one carrier transfer and prepares for the next transfer. This design ensures that the carrier transfer mechanism remains sterile at all times, reducing the risk of contamination from the source, further guaranteeing the hygiene and safety of the infusion container disinfection process and the reliability of the disinfection effect, ensuring that each disinfection carrier is in optimal cleanliness before use.

[0074] The following is in conjunction with the appendix Figures 1-19 The present invention will be described in further detail below.

[0075] Example 1: A device for disinfecting infusion containers is disclosed, with reference to... Figures 1-4The system includes a support 10 and a controller 200. The support 10 includes a lower support rod 11 and an upper main support 12. The main support 12 is equipped with a feeding station 100, a liquid supply station 101, a disinfection station 102, a recovery station 103, and a carrier transfer mechanism 80. The feeding station 100 is used to provide a disinfection carrier 223. The disinfection carrier 223 is a sheet or ball made of cotton, cotton balls, or other fibrous materials, which can absorb liquid disinfectant. The following discussion will use cotton as an example to illustrate the disinfection carrier 223. The liquid supply station 101 is used to provide liquid disinfectant to the disinfection carrier 223 so that the disinfection carrier 223 is soaked in liquid disinfectant. The liquid disinfectant can be iodine or... The device includes an alcohol supply station; a disinfection station 102 is used to drive the disinfection carrier 223, which is soaked in liquid disinfectant, to disinfect the head of the infusion container 90; a recycling station 103 is used to recycle the used disinfection carrier 223; a carrier transfer mechanism 80 is used to drive the disinfection carrier 223 from the supply station 100 through the liquid supply station 101 and the disinfection station 102 to the recycling station 103; a controller 200 is used to control the entire disinfection device; the main support 12 includes a support frame 121 and a worktable 122 fixed on the support frame 121; the disinfection carrier 223 can be circular or square, and for ease of explanation, a square disinfection carrier 223 will be used as an example in the following description.

[0076] In other embodiments, the feeding station 100, the liquid supply station 101, the disinfection station 102, and the recovery station 103 are not distributed sequentially. Alternatively, the recovery station 103 can be placed between the liquid supply station 101 and the disinfection station 102. When the liquid supply station 101 provides liquid disinfectant to the disinfection carrier 223, the disinfection carrier 223, which is soaked in liquid disinfectant, first goes to the disinfection station 102 to disinfect the head of the infusion container, and then returns to the recovery station 103 to disinfect the carrier 223. This way, the movement path of the disinfection carrier 223 can be disinfected.

[0077] refer to Figure 3 and Figure 5The carrier transfer mechanism 80 includes a turntable 82 and a transfer drive motor 81; wherein the transfer drive motor 81 serves as a transfer drive component 88, and the turntable 82 serves as a carrier drive component 89; the transfer drive motor 81 is a servo geared motor; the transfer drive motor 81 is fixed inside the main support 12 and the output shaft of the transfer drive motor 81 passes vertically through the worktable 122; the turntable 82 is coaxially fixed to the upper end of the output shaft of the transfer drive motor 81; the turntable 82 is located on the upper side of the main support 12; in order to drive the disinfection carrier 223, a first transfer pusher 83 is fixed on the turntable 82. The disinfection carrier 223 is transferred from the feeding station 100 to the liquid supply station 101, and from the liquid supply station 101 to the disinfection station 102 entirely by the first transfer pusher 83. To more precisely control the rotation of the turntable 82, several vertically penetrating position detection holes 822 are formed on the turntable 82. A micro switch 84 is installed on the bottom surface of the worktable 122. The micro switch 84 cooperates with the position detection holes 822 and is used to control the transfer drive motor 81. When the contact of the micro switch 84 is directly facing the position detection hole 822, the transfer drive motor 81 stops rotating. In other embodiments, the triggering structure can use a protrusion instead of the position detection hole 822. The protrusion can be integrally formed or detachably connected to the bottom surface of the turntable 82. The detachable connection can be achieved by using screws or embedding.

[0078] refer to Figures 5-8 The feeding station 100 has a carrier feeding mechanism 20; the carrier feeding mechanism 20 includes a support sleeve 21 and a carrier box 22; the carrier box 22 includes a square columnar carrier box body 221 with an open bottom, a counterweight 222 disposed inside the carrier box body 221, and several vertically stacked disinfection carriers 223; the carrier box body 221 can be made of plastic and has one open end and the other closed end; the counterweight 222 is located on the upper side of all the disinfection carriers 223; the counterweight 222 and the disinfection carriers 223 are vertically movable inside the carrier box body 221. To prevent the counterweight 222 from detaching from the carrier box body 221, a vertical guide block 2221 is formed on the vertical end face of the counterweight 222, and a sliding guide groove 2210 that mates with the vertical guide block 2221 is formed on the inner side wall of the carrier box body 221; the lower end of the sliding guide groove 2210 near the opening of the carrier box body 221 is closed; the support sleeve 21 has a vertically penetrating square groove-shaped mounting hole 210 that mates with the carrier box body 221; the mounting hole 210... A vertical limiting block 211 is formed at the bottom of the side wall of 10; a square annular groove-shaped sleeve clearance groove 2214 that cooperates with the vertical limiting block 211 is formed at the lower end of the outer side wall of the carrier box body 221; in this way, when the carrier box 22 is vertically inserted into the placement hole 210 of the support sleeve 21, the vertical limiting block 211 enters the sleeve clearance groove 2214 of the carrier box body 221 and abuts against the upper side wall of the sleeve clearance groove 2214, so that the carrier box body 221 will not slide down.

[0079] refer to Figure 5 and Figure 9 To avoid obstructing the first transfer pusher 83, the lower middle part of the lower end of the opposite pair of side walls of the carrier box body 221 is formed with a discharge notch 2211. To prevent the discharge notch 2211 from being mispositioned when the carrier box 22 is vertically inserted into the placement hole 210 of the support sleeve 21, the lower middle part of the lower end of the opposite pair of side walls of the carrier box body 221 is formed with a discharge notch 2211. In this way, no matter how the carrier box 22 is inserted, the discharge notch 2211 will be in the correct position. However, the discharge of the disinfection carrier 223 is smoother with one pair of discharge notches 2211 than with two pairs of discharge notches 2211. To maintain this advantage, when there is only one pair of discharge notches 2211, a guide strip or guide groove for preventing mis-installation can be provided on the outer surface of the carrier box body 221, and a guide groove or a guide strip for cooperating with the guide strip can be provided on the support sleeve 21.

[0080] In addition, in order for the disinfection carrier 223 to smoothly leave the carrier box body 221 through the discharge notch 2211, the width of the discharge notch 2211 is greater than or equal to the width of the disinfection carrier 223, and the height of the discharge notch 2211 is greater than or equal to the thickness of the disinfection carrier 223.

[0081] refer to Figure 6 and Figure 7 The liquid supply station 101 has a liquid disinfectant spraying mechanism 30. The liquid disinfectant spraying mechanism 30 includes a liquid disinfectant supply bracket 31 fixed to the upper surface of the workbench 122, a peristaltic pump disposed within the liquid disinfectant supply bracket 31, a liquid disinfectant storage bottle 32 detachably connected to the liquid disinfectant supply bracket 31, and a liquid disinfectant nozzle 33. The liquid disinfectant storage bottle 32 can be connected to the liquid disinfectant supply bracket 31 by screwing and is connected to the inlet end of the peristaltic pump. The liquid disinfectant nozzle 33 is fixed to the liquid disinfectant supply bracket 31 and connected to the outlet end of the peristaltic pump. The outlet of the liquid disinfectant nozzle 33 is vertically facing the turntable 82. In other embodiments, the liquid disinfectant spraying mechanism 30 is replaced by a liquid disinfectant dripping mechanism. When using the liquid disinfectant dripping mechanism, the liquid disinfectant reaches the disinfection carrier 223 in a dripping manner.

[0082] To further improve the safety of infusion, the contact area between the turntable 82 and the disinfection carrier 223 also needs to be disinfected. A sterilization component 35 is provided on the liquid disinfectant supply bracket 31, and the sterilization component 35 can be an ultraviolet lamp.

[0083] refer to Figure 4 and Figures 10-12The disinfection station 102 has a disinfection drive mechanism 60; the infusion container 90 is located directly above the disinfection drive mechanism 60; the disinfection drive mechanism 60 includes a carrier rotating gripper 63, a rotating drive assembly 61, and a lifting drive assembly 62; the lifting drive assembly 62 is used to drive the carrier rotating gripper 63 to move vertically up and down; the rotating drive assembly 61 is used to drive the carrier rotating gripper 63 to rotate; the carrier rotating gripper 63 includes a gripper spindle 631, a circular connecting ring 632 coaxially formed in the middle of the gripper spindle 631, and a gripping part provided at the upper end of the gripper spindle 631; an intermediate support frame 13 is fixed inside the main support 12; the rotating drive assembly 61 includes a rotating drive motor 611 fixed on the intermediate support frame 13, a connecting frame 612 fixed on the output shaft of the rotating drive motor 611, and a vertical insertion rod 613 fixed on the connecting frame 612 and coaxially arranged with the output shaft of the rotating drive motor 611; the vertical insertion rod 613 The circumferential surface of the clamp has several evenly distributed vertical guide bars 6131; the length direction of the vertical guide bars 6131 is parallel to the axis of the vertical insert rod 613; the lower end surface of the clamp spindle 631 has a vertical guide groove that mates with the vertical insert rod 613; the rotary drive motor 611 is a servo geared motor; the lifting drive assembly 62 includes an electromagnet 621 fixed on the intermediate support frame 13, a vertical connecting rod 623 passing vertically through the electromagnet 621, and a fixed... The armature 622 at the upper end of the vertical connecting rod 623 is magnetic when the electromagnet 621 is energized, causing the armature 622 of the same polarity to move upward. Then, the electromagnet 621 is de-energized and loses its magnetism, and the armature 622 moves downward under its own weight. The vertical end face of the piston rod away from the electromagnet 621 of the armature 622 has a central rotating groove 6221 formed in the middle, which mates with the connecting ring 632. The upper and lower parts respectively have U-shaped rotating grooves 6222 on both sides that mate with the gripper spindle 631. In order to improve the quality of sterilization, the gripping part includes a central abutment part 633 and several driving claws 634. The central abutment part 633 is coaxially arranged with the rotation center axis of the carrier rotating gripper 63. All the driving claws 634 are evenly distributed around the circumference of the central abutment part 633. The central abutment part 633 is higher than the driving claws 634. Additionally, the upper end of the driving gripper 634 is trapezoidal in diameter, which facilitates the driving gripper 634 in better pressing down on the disinfection carrier 223; Reference Figure 5 In order to avoid the lifting and lowering of the carrier rotating gripper 63, the worktable 122 and the turntable 82 are formed with avoidance holes 820 for the carrier rotating gripper 63 to pass through vertically.

[0084] In other embodiments, the disinfection drive mechanism 60 adopts a different structure, with a sliding frame 624 fixed on the intermediate support frame 13; for details of the structure of the disinfection drive mechanism 60, please refer to [reference needed]. Figure 13The lifting drive assembly 62 includes a lifting drive motor 625 fixed on the intermediate support frame 13, a lifting lead screw 626 coaxially fixed on the output shaft of the lifting drive motor 625, a slider 627 slidably disposed on the sliding frame 624, and a lead screw nut fixed on the slider 627. The lead screw nut and the lifting lead screw 626 form a lead screw pair. The lifting drive motor 625 is a servo motor. The rotation drive assembly 61 only includes a rotation drive motor 611. The carrier rotation gripper 63 is coaxially fixed on the upper end of the output shaft of the rotation drive motor 611.

[0085] refer to Figure 6 A disinfectant carrier detection sensor 34 is installed on the liquid disinfectant supply bracket 31. The disinfectant carrier detection sensor 34 uses an infrared sensor or a laser sensor to detect whether the disinfectant carrier 223 is missing. However, when the liquid disinfectant is alcohol, the disinfectant carrier detection sensor 34 can also use an alcohol sensor. When this technical solution is working, if the disinfectant carrier 223 is missing, the clearance hole 820 will not be blocked. In this way, the alcohol sprayed from the liquid disinfectant nozzle 33 will pass through the clearance hole 820, so the turntable 82 will not be contaminated with alcohol. At this time, the disinfectant carrier detection sensor 34 determines whether the disinfectant carrier 223 is missing by judging the presence or absence of alcohol. At this time, the clearance hole 820 acts as a passage hole for alcohol to pass through.

[0086] refer to Figures 1-3 The infusion container 90 is switched via the infusion container switching mechanism 40. The infusion container switching mechanism 40 includes a switching motor 41 and a switching turntable 42 fixed within the main support 12. The switching motor 41 is a servo geared motor. The output shaft of the switching motor 41 passes through the worktable 122, and the switching turntable 42 is coaxially fixed to the upper end of the output shaft of the switching motor 41. At least two infusion containers 90 are detachably connected to the switching turntable 42. The head of the infusion container 90 is set downwards. The connection between the infusion container 90 and the switching turntable 42 can be a snap-fit ​​type. To facilitate the insertion of the puncture needle, a puncture needle insertion and removal mechanism 50 is also provided on the main support 12. The puncture needle insertion and removal mechanism 50 includes a puncture needle insertion and removal drive cylinder 51 fixed on the main support 12 and a retainer 52 fixed on the piston rod of the puncture needle insertion and removal drive cylinder 51. The retainer 52 is used to retain the puncture needle.

[0087] refer to Figure 3The recycling station 103 has a carrier recycling mechanism 70, which includes a compression block 71 fixed on the support sleeve 21 and a recycling bin 72 fixed in the main support 12. The workbench 122 has a recycling hole 1220 formed on the recycling bin 72. The compression block 71 is higher than the first transfer pusher 83, and the distance between the lower end faces of the compression block 71 and the first transfer pusher 83 is less than the thickness of the disinfection carrier 223. The recycling bin 72 is located outside the turntable 82 and lower than the turntable. 82; To allow the disinfection carrier 223 to smoothly pass through the recycling hole 1220 and enter the recycling bin 72, the end of the extrusion block 71 away from the support sleeve 21 is formed with an extrusion surface 711. The extrusion surface 711 guides the disinfection carrier 223 to detach from the turntable 82 and enter the recycling bin 72 through the recycling hole 1220. The extrusion surface 711 is vertical and forms a certain angle with the vertical plane of the turntable 82 passing through its rotation center axis. In the rotation direction of the turntable 82, the inner end of the extrusion surface 711 is located in front of the outer end. To facilitate the disinfection carrier 223 to smoothly pass through the recycling hole 1220 and enter the recycling bin 72 after detaching from the turntable 82, a blocking plate is formed on the upper surface of the workbench 122. The blocking plate is located on the outer side of the recycling hole 1220 away from the turntable 82, and its surface near the turntable 82 is flush with the corresponding inner wall of the recycling hole 1220.

[0088] In other embodiments, turntable 82 can be replaced by an annular conveyor belt.

[0089] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 5 and Figures 7-9 In order to recycle unused disinfectant carriers 223, a lower limiting member 2212 is provided at the bottom of the carrier box body 221. The lower limiting member 2212 can be a limiting protrusion or a limiting plate protruding inward from the inner wall of the carrier box body 221. There are at least two limiting protrusions or limiting plates, which are arranged diagonally. Due to the presence of the limiting protrusions or limiting plates, there is a certain distance between the lower end face of the lowest disinfectant carrier 223 and the upper end face of the turntable 82. When the first transfer pusher 83 drives the lowest disinfectant carrier 223 to rotate with the turntable 82, the disinfectant carrier 223 will first arch downward and then detach from the carrier box body 221. After detaching from the carrier box body 221, the disinfectant carrier 223 will return to its original position. This change will make the position of the disinfectant carrier 223 on the turntable 82 inaccurate, which is not conducive to the disinfectant carrier 223 spraying liquid disinfectant and disinfecting the head of the infusion container 90.

[0090] To solve the above technical problems, refer to Figure 5A circular upper convex ring 821 is coaxially arranged on the turntable 82; the upper convex ring 821 passes through the discharge notch 2211; the first transfer pusher 83 is located on the upper end surface of the upper convex ring 821; the upper end surface of the upper convex ring 821 is higher than the limiting protrusion or the limiting protrusion plate, so that due to the counterweight 222 and the upper disinfection carrier 223, the lowermost disinfection carrier 223 abuts against the upper end surface of the upper convex ring 821, and then the first transfer pusher 83, which rotates with the turntable 82, can bring the lowermost disinfection carrier 223 out from the discharge notch 2211. During this process, the position of the lowermost disinfection carrier 223 is more stable.

[0091] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figure 9 In order for nurses to know more quickly the remaining amount of disinfectant carrier 223 in the carrier box body 221, so as to plan the replacement time of carrier box 22 in advance.

[0092] refer to Figure 6 The carrier box body 221 is transparent, so that the remaining amount of disinfectant carrier inside the carrier box body 221 can be directly observed.

[0093] To more quickly observe the remaining amount of disinfectant carrier inside the carrier box body 221, at least one remaining amount character 2213 is provided on the outer surface of the carrier box body 221, which is transparent. The remaining amount character 2213 corresponds to the uppermost disinfectant carrier 223 to determine the remaining amount of disinfectant carrier 223 inside the carrier box body 221. The remaining amount character 2213 can be a number or a symbol. Taking the remaining amount character 2213 as a number as an example, when there is more than one remaining amount character 2213, the size of the remaining amount character 2213 decreases regularly along the direction close to the opening of the carrier box body 221, such as decreasing arithmetic progression. However, if the thickness of the disinfectant carrier 223 is very small, such as 2 mm, then the thickness of a dozen or so disinfectant carriers 223 is still very small. In this case, if the remaining amount character 2213 is still used, the characters of the remaining amount character 2213 will be very small, making them difficult to see. Therefore, the remaining amount character 2213 is not suitable for this situation.

[0094] In other embodiments, reference is made to Figure 8With the carrier box body 221 transparent, the feeding station 100 has a carrier monitoring component 23, which monitors the remaining amount of disinfectant carrier 223 inside the carrier box body 221. Specifically, an outer support plate 24 is fixed on the workbench 122, and the carrier monitoring component 23 is a color mark sensor fixed on the outer support plate 24. Furthermore, with the carrier box body 221 transparent, the counterweight 222 can have a set color, such as yellow or red, different from the color of the disinfectant carrier 223. Additionally, a monitoring clearance hole 212 is formed on the side wall of the support sleeve 21, located between the carrier box body 221 and the color mark sensor. To reduce costs, the counterweight 222 can be made of acrylic sheet with a set color.

[0095] Alternatively, the carrier monitoring component 23 can also use a metal sensor, and the counterweight 222 can be made of metal. In this technical solution, the carrier box body 221 can be transparent or opaque, but the carrier box body 221 must be made of non-metallic material.

[0096] Example 4: The difference between Example 4 and Example 1 is as follows: (Refer to...) Figures 14-16 The structure of the first transfer pusher 83 is different and the extrusion block 71 can be flush with the lower end face of the first transfer pusher 83. The specific structure is as follows: A horizontal clearance groove 710 is formed on the extrusion block 71 through which the first transfer pusher 83 passes. However, the disinfection carrier 223 cannot pass through the horizontal clearance groove 710. Thus, when the first transfer pusher 83 moves the disinfection carrier 223 to the extrusion block 71, since the disinfection carrier 223 cannot pass through the horizontal clearance groove 710, the disinfection carrier 223 will be guided by the extrusion surface 711 to leave the turntable 82 and then smoothly pass through the recycling hole 1220 into the recycling bin 72. After that, the first transfer pusher 83 passes through the horizontal clearance groove 710 and continues to move forward.

[0097] To further enhance the guiding effect of the extrusion block 71, the horizontal clearance groove 710 is divided into three clearance slots. Simultaneously, the first transfer pusher 83 includes three pusher blocks 833 radially distributed along the turntable 82. Each clearance slot corresponds one-to-one with a pusher block 833. This makes it more difficult for the disinfection carrier 223 to pass through the horizontal clearance groove 710, while also ensuring a more complete extrusion surface 711 and better guiding effect. Furthermore, the three pusher blocks 833 can apply driving force to the disinfection carrier 223 from three radial positions, thereby more stably driving the disinfection carrier 223 to rotate with the turntable and reducing slippage or deviation of the disinfection carrier 223 during movement. In other embodiments, the number of clearance slots can also be two or more than three.

[0098] To prevent the bottom disinfectant carrier from being pulled out by the friction of the turntable 82 before the first transfer pusher 83 arrives, the feeding station 100 has a blocking member 25, which is installed on the support sleeve 21. The blocking member 25 is located on the side of the support sleeve 21 near the liquid supply station 101. The blocking member 25 prevents the disinfectant carrier 223 from moving together with the turntable 82. A blocking drive member 823 is fixed on the turntable 82. The blocking drive member 823 is used to drive the blocking member 25 to avoid the disinfectant carrier 223.

[0099] For detailed structure reference Figure 15 and Figure 16 The blocking member 25 has a blocking shaft 251, a blocking part 252, and a clearance driving part 253. The blocking part 252 is radially fixed on the blocking shaft 251. The clearance driving part 253 is radially fixed on the end of the blocking shaft 251 and the direction of the clearance driving part 253 is in the same radial direction as the direction of the blocking part 252. The blocking part 252 is rotatably connected to the support sleeve 21 through the blocking shaft 251. The axial direction of the blocking shaft 251 is parallel to the turntable 82. The clearance driving part 253 is located on the moving path of the blocking driving member 823.

[0100] During operation, when the turntable 82 begins to rotate to transfer the disinfection carrier 223, the blocking drive member 823 fixed on the turntable 82 rotates together with the turntable and gradually approaches the avoidance drive part 253 of the blocking member 25. As the turntable 82 continues to rotate, the blocking drive member 823 comes into contact with the avoidance drive part 253 and applies force to it. The avoidance drive part 253 converts this force into a rotational torque around the blocking shaft 251, causing the blocking part 252 to swing upward around the blocking shaft 251. Since the axis of the blocking shaft 251 is parallel to the turntable 82, the swing trajectory of the blocking part 252 is located in a vertical plane. After swinging upward, the free end of the blocking part 252 will rise to a height higher than the disinfection carrier 223, thereby completely avoiding the movement path of the disinfection carrier 223. At this time, the first transfer pusher 83 can smoothly push the disinfection carrier 223 through under the blocking member 25 and enter the next station. When the blocking drive 823 passes the avoidance drive 253 as the turntable 82 rotates, the force on the avoidance drive 263 disappears, and the blocking part 252 swings downward and resets to its horizontal blocking state under the action of gravity, waiting for the arrival of the next disinfection carrier 223. In other embodiments, a torsion spring can be sleeved on the blocking shaft 251, with one end of the torsion spring fixed to the support sleeve 21 and the other end fixed to the blocking part 252, so that the blocking part 252 returns to its position more quickly and accurately.

[0101] In other embodiments, the blocking member 25 is arranged in a translational manner rather than a rotational manner. The front end of the blocking drive member 823 in the direction of movement is provided with an inclined drive guide surface. As the blocking drive member 823 moves, the drive guide surface of the blocking drive member 823 will drive the blocking member 25 to move as a whole through the avoidance drive part 253, thereby causing the blocking part 252 to move away from the movement path of the disinfection carrier 223, thereby avoiding the disinfection carrier 223. In addition, a compression spring is provided on the support sleeve 21. After the blocking drive member 823 passes the avoidance drive part 253, the compression spring drives the blocking part 252 back to the movement path of the disinfection carrier 223 to block the next disinfection carrier 223.

[0102] Example 5: The difference between Example 5 and Example 4 is as follows: (Refer to...) Figure 17 and Figure 18 In this embodiment, a rotating arm 85 replaces the turntable 82, and a second transfer pusher 86 replaces the first transfer pusher 83. In this case, the blocking member 25 and the blocking drive member 823 are unnecessary. The second transfer pusher 86 is located on the upper end face of the rotating arm 85. The rotating arm 85 and the turntable 82 serve as placement parts 891 to hold the disinfection carrier 223, while the second transfer pusher 86 and the first transfer pusher 83 serve as pushing parts 892 to drive the disinfection carrier 223 out of the carrier box 22. The second transfer pusher 86 can also be divided into several sections, similar to the first transfer pusher 83 in Embodiment 4.

[0103] Since the rotating arm 85 is not always located under the carrier box 22 like the turntable 82, the rotating arm 85 only comes into contact with the disinfection carrier 223 when it is transporting the disinfection carrier 223. This prevents friction with the disinfection carrier 223 from accidentally pulling the disinfection carrier 223 out of the carrier box body 221. At the same time, by reducing the contact time with the disinfection carrier 223, the possibility of the disinfection carrier 223 being contaminated is reduced, and the disinfection carrier 223 can be kept cleaner.

[0104] refer to Figure 18 Because of the lack of a long-term contact support like the turntable 82, the disinfection carrier 223 may accidentally fall out of the carrier box body 221. To avoid this, a blocking strip 73 is provided on the extrusion block 71. The blocking strip 73 is located directly below the carrier box body 221 to prevent the disinfection carrier 223 from falling downwards out of the carrier box body 221. To avoid the blocking strip 73, the rotating arm 85 and the second transfer pusher 86 are provided with blocking strip clearance grooves 850 that cooperate with the blocking strip 73. For easier processing, the blocking strip clearance grooves 850 are the gaps between the blocks of the second transfer pusher 86.

[0105] refer to Figure 17Since the width of the rotating arm 85 is limited, in order to control the position of the rotating arm 85 more accurately, a contact sensor 87 is set on the worktable 122. When the rotating arm 85 triggers the contact sensor 87, the angle of the transfer drive motor 81 is the origin. The controller 200 calculates the position of each station by the rotation angle of the transfer drive motor 81. The contact sensor 87 can be an infrared switch sensor.

[0106] In other embodiments, the placement part 891 and the pushing part 892 can be a module, and this module can be connected to the transfer drive motor 81 by means of a disc or a cantilever. That is, this module is set on the disc or cantilever, and the transfer drive motor 81 drives the disc or cantilever to rotate.

[0107] The above embodiments are for disinfection carriers 223 that have not adsorbed liquid disinfectant. In other embodiments, when the feeding station 100 provides disinfection carriers 223 that have adsorbed liquid disinfectant, the liquid disinfectant spraying mechanism 30 or liquid disinfectant dripping mechanism at the feeding station 101 can be eliminated. However, the disinfection carrier detection sensor 34 and the sterilization component 35 can still be retained. In this case, the disinfection carrier detection sensor 34 uses an infrared sensor or a laser sensor instead of an alcohol sensor. The disinfection carrier detection sensor 34 is used to detect whether the carrier transfer mechanism 80 has obtained the disinfection carrier 223 from the feeding station 100.

[0108] In addition to its use in the medical field, this application can also be used as an educational and educational medical toy.

[0109] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
