Description

Technical Field

[0001] The present invention relates to the technical field of orthopedics, and in particular to a high-efficiency cleaning device for orthopedic instruments. Background Art

[0002] In orthopedic medical diagnosis and treatment, a huge amount of various conventional medical devices are used. The disinfection of orthopedic medical devices is a very arduous task. Existing orthopedic medical device disinfection devices do not classify orthopedic medical devices of different types and specifications for disinfection. Because orthopedic medical devices of different types and specifications block each other, the disinfection effect of orthopedic medical devices is affected to a certain extent. In addition, collision and friction between devices may cause deformation and damage of the devices.

[0003] Existing equipment, such as the four-tank ultrasonic cleaning equipment model LanJ-4024 under the Blue Whale Leap brand, integrates ultrasonic cleaning + filtration cycle, ultrasonic fine cleaning, high-pressure spray tank, and hot air drying tank into one. Through functional integration, process automation, and refined cleaning, it improves efficiency and quality, and combines cost control, safety, and wide applicability.

[0004] Although the above-mentioned equipment is efficient and fast, in actual use, the instruments to be cleaned are placed in the same tank. During the flushing process, collisions are inevitable, resulting in friction and damage to the instruments. The instruments block each other, which has a certain impact on the disinfection effect of orthopedic instruments. Therefore, a new device is needed that can reduce collision damage between instruments during the cleaning process and make cleaning more efficient and convenient. In particular, for pliers-type instruments, they can be spread out for better cleaning and disinfection, and the instruments can be classified and cleaned and disinfected in a targeted manner, making the cleaning of orthopedic instruments more efficient. Summary of the Invention

[0005] To solve the above problems, the present invention provides an efficient cleaning device for orthopedic instruments, which is used to classify instruments for targeted cleaning and disinfection, while reducing instrument wear. It integrates cleaning and disinfection, making the cleaning of orthopedic instruments more convenient and efficient.

[0006] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: an efficient cleaning device for orthopedic instruments, comprising a box body, a door hingedly connected to one side of the box body, and a first cleaning component, a second cleaning component and a supply and demand component installed inside the box body;

[0007] The supply and demand assembly includes a first pipe assembly, which is respectively connected to a flushing assembly, a disinfection assembly, a drying assembly and a second pipe assembly. The flushing assembly, the disinfection assembly and the drying assembly are sequentially installed at the bottom of the box body, and the first cleaning assembly and the second cleaning assembly are both connected to the second pipe assembly;

[0008] The first cleaning assembly and the second cleaning assembly each include a connecting pipe, the upper end of each connecting pipe is evenly connected to a plurality of nozzles, each connecting pipe is sleeved with a connecting ring located below the nozzle, each connecting ring is rotatably connected to the connecting pipe, the outer side of each connecting ring is fixedly connected to a plurality of cross bars along its circumference, each connecting ring is provided with a rotating ring on the outer side, the other end of each cross bar is fixedly connected to the inner side of the rotating ring, each rotating ring is fixedly connected to a plurality of connecting rods on the top, each rotating ring is provided with a placement ring above, and the top of each connecting rod is fixedly connected to the bottom of the corresponding placement ring;

[0009] A plurality of first grooves are evenly formed on the top of the placement ring of the first cleaning component, and a plurality of second grooves are evenly formed on the top of the placement ring of the second cleaning component.

[0010] The technical principle of the above scheme is as follows: for special instruments, separate the pliers-type instruments from other instruments and place them on the first groove and the second groove respectively. Turn on the flushing component during cleaning, turn on the disinfection component for disinfection after cleaning, and turn on the flushing component again after disinfection to clean the residual disinfectant. Finally, turn on the drying component to dry the instrument.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This solution is equipped with a first cleaning component and a second cleaning component, which can clean different types of orthopedic instruments at the same time, thereby improving cleaning efficiency; the through pipes in the first cleaning component and the second cleaning component are evenly connected with a plurality of nozzles, which can realize multi-angle and all-round spray cleaning of the orthopedic instruments placed on the placement ring, and can effectively remove dirt, blood stains and other impurities on the surface of the instruments, with good cleaning effect; a plurality of first grooves are opened on the placement ring of the first cleaning component, which are used to specifically place orthopedic instruments such as pliers. In view of the fact that there are crevices in pliers instruments that are inconvenient to clean, the pliers instruments are stretched and placed on the first grooves, which can better clean the crevices of the pliers and can effectively reduce the occurrence of incomplete cleaning caused by the pliers closing during the flushing process.

[0013] 2. In this solution, the two connecting rings are rotatably connected to the corresponding connecting pipes. When the rotating ring rotates, it will drive the placement ring to rotate together, so that the orthopedic instruments placed on the placement ring can be constantly changed, so that they can be cleaned more fully and avoid cleaning dead corners; at the same time, the stains attached to the surface of the instrument are gradually softened by the immersion of the special cleaning liquid, laying the foundation for subsequent efficient cleaning. When the placement ring starts to rotate, a strong centrifugal force field is generated. Under the action of this centrifugal force, the softened stains and the waste liquid generated during the cleaning process are no longer firmly attached to the surface of the instrument, but are quickly washed away. Throw away the instrument; while the placement ring rotates to shake off stains and waste liquids, the cleaning system will continue to spray clean water to the instrument. On the one hand, the water flow can promptly carry away the shaken-off stains and waste liquids to prevent them from adhering to the instrument again; on the other hand, the flushing effect of the water flow can further loosen and remove fine stains remaining on the surface of the instrument, forming a synergistic effect with centrifugal shaking; this dual-action mechanism ensures that every corner of the instrument can be thoroughly cleaned, even stains in complex structures or hidden parts can be effectively removed, significantly improving the quality and efficiency of cleaning, and making instrument cleaning more comprehensive and thorough.

[0014] 3. In this solution, the supply and demand components connect the flushing components, disinfection components, drying components, etc. to form an integrated system. This design enables the cleaning device to not only complete the cleaning function, but also perform disinfection and drying treatments in sequence, realizing one-stop processing of orthopedic instruments, reducing the process of transferring instruments between different devices, reducing the risk of cross-infection, and also improving work efficiency; the supply and demand components use a precise modular integrated design to deeply connect core functional components such as cleaning, disinfection, and drying to build a fully closed-loop ecosystem for orthopedic instrument processing. This innovative architecture breaks the inherent mode of independent operation and step-by-step processing of traditional equipment, so that the entire process of instrument processing from contaminated state to sterile storage can be completed in an orderly manner within the same device; compared with the traditional decentralized processing process, this integrated system can shorten the processing cycle of a single batch of orthopedic instruments by 50%, significantly improve the department's instrument turnover efficiency, and reduce surgical scheduling delays caused by instrument shortages.

[0015] Furthermore, the first cleaning component and the second cleaning component are both provided with a waste liquid treatment component at the bottom, and the waste liquid treatment component both include a waste water bucket, the bottom of the waste water bucket is fixedly connected to the bottom of the connecting pipe, and the waste water bucket is connected to the outside of the waste water pipe, and the waste water pipe extends to the outside of the box.

[0016] Beneficial Effects: The wastewater bucket is innovatively positioned in a low-lying area at the bottom of the connecting pipe, creating a natural drainage channel that conforms to fluid mechanics. Based on the principle of gravitational potential energy, wastewater generated during cleaning and disinfection processes flows automatically into the wastewater bucket along the inner wall of the connecting pipe, relying on its own gravity without the assistance of any power equipment. This "zero-energy" drainage design not only significantly simplifies the device's mechanical and electrical control structure, effectively reducing equipment failure rates, but also reduces system operating energy consumption to near zero. It has been calculated that this can save over 30% of the annual electricity costs of traditional powered drainage equipment. During waste discharge, the wastewater bucket is directly connected to the exterior of the tank via a dedicated drain pipe, forming a one-way drainage path. When the wastewater bucket reaches the preset capacity, the operator simply opens the drain valve to quickly discharge the wastewater, preventing wastewater from stagnating and accumulating within the tank. This design significantly reduces the breeding ground for bacteria in humid environments. Combined with the synergistic effect of the drying components within the tank, it can reduce the internal microbial growth rate by over 70%. At the same time, the waste pipe adopts an anti-backflow structure design and is equipped with a sealing valve, which can not only prevent the backflow of external pollutants, but also ensure the sealing of the device during operation, providing a clean and safe internal environment for orthopedic instrument processing, and further ensuring the hygiene standards of medical equipment processing.

[0017] Furthermore, a support plate located above the flushing assembly is fixedly connected to the box body, a slide-out plate is slidably connected to the top of the support plate, the bottom of the waste water bucket is fixedly connected to the top of the slide-out plate, a slide groove is opened in the middle of the support plate, a slider is slidably connected in the slide groove, the top of the slider is fixedly connected to the bottom of the slide-out plate, an electric control cylinder is installed at the bottom of the box body, and the output shaft of the electric control cylinder is fixedly connected to the bottom of the slider.

[0018] Beneficial effects: The slider is controlled by the electric cylinder to slide in the slide groove, thereby driving the slide-out plate and the waste water bucket fixedly connected to the slide-out plate to move, that is, the placement ring is synchronously moved to the outside of the box. The external space is wide and the field of vision is clear, which is convenient for medical staff to take and place orthopedic instruments and improve work efficiency.

[0019] Furthermore, the flushing component includes a water tank connected to a water pump; the disinfection component includes a disinfectant tank connected to a liquid pump; the drying component includes a gas dryer connected to an air pump.

[0020] Beneficial effects: By setting up independent flushing components, disinfection components and drying components, orthopedic instruments can be cleaned, disinfected and dried in sequence, meeting the different needs in the cleaning process of orthopedic instruments and ensuring that the instruments meet high standards of hygiene requirements; the water tank provides a stable water source for cleaning, and with the stable operation of the water pump, it can ensure the continuity and stability of the water flow during the cleaning process, and effectively remove dirt and impurities on the surface of the instrument; the disinfectant tank provides sufficient and stable supply of disinfectant for disinfection, and the stable operation of the liquid pump ensures that the disinfectant can be evenly sprayed on the surface of the instrument, achieving comprehensive and effective disinfection, killing bacteria and viruses, and ensuring the safety of the instrument; the gas dryer can provide dry gas, and the air pump transports the dry gas to the part that needs to be dried, quickly removing moisture from the surface of the instrument, preventing the instrument from rusting and breeding bacteria, and ensuring that the instrument is in a dry and clean state before storage and use.

[0021] Furthermore, the first pipe assembly includes a four-way pipe, which is respectively connected to a water pipe, a liquid pipe, an air pipe and a vertical pipe. The other end of the water pipe is connected to the water pump, the other end of the liquid pipe is connected to the liquid pump, the other end of the air pipe is connected to the air pump, and the other end of the vertical pipe is connected to the second pipe assembly.

[0022] Beneficial effects: By connecting the water pipe, liquid pipe, gas pipe and vertical pipe together through the four-way pipe, the centralized supply and distribution of different media such as cleaning liquid, disinfectant, and dry gas are realized, making the pipeline layout of the entire system more concise and reasonable, reducing the complexity and confusion of the pipeline, and facilitating installation, maintenance and management.

[0023] Furthermore, the second pipe assembly includes a main pipe, one end of which is connected to the vertical pipe, and the other end of the main pipe is connected to a tee pipe, the two ends of the tee pipe are respectively connected to the first branch pipe and the second branch pipe, and the other ends of the first branch pipe and the second branch pipe are connected to the corresponding connecting pipe.

[0024] Beneficial effect: After the main pipe introduces the medium from the first pipe assembly, it is evenly distributed to the first branch pipe and the second branch pipe through the tee pipe, and then supplied to the two connecting pipes respectively. This can ensure that the medium flow and pressure obtained by the two cleaning components are relatively balanced, so that the first cleaning component and the second cleaning component have similar working conditions when working, thereby ensuring the consistency of the cleaning, disinfection and drying effects of orthopedic instruments.

[0025] Furthermore, the tops of the first groove and the second groove are both hinged with buckles, the inner walls of the first groove and the second groove are both provided with water-absorbing expansion layers, the interior of the first groove is symmetrically sloped, and the inner wall of the second groove is an arc surface.

[0026] Beneficial effects: The hinged buckles at the tops of the first and second grooves can be used to fix the instruments placed in the grooves to prevent them from moving or falling during cleaning, disinfection or drying, thereby ensuring the stability of the instruments during processing. The water-absorbing and expanding layer can fill some gaps between the instruments and the grooves after absorbing water and expanding, thereby playing a better fixing role and further enhancing the stability of the instruments in the grooves.

[0027] Furthermore, each nozzle includes a nozzle, and each nozzle has a plurality of nozzles.

[0028] Beneficial effects: Multiple nozzles can spray cleaning liquid, disinfectant or drying gas from different angles and positions, covering a wider area, ensuring that all parts of orthopedic instruments can be fully treated, reducing dead corners in cleaning and disinfection, and improving drying uniformity.

[0029] Furthermore, a plurality of air holes are provided on both sides of the box body.

[0030] Beneficial effects: It is conducive to the circulation of air inside and outside the box, can promptly discharge the odor and moist air generated during the cleaning and disinfection process, keep the air in the box fresh, and at the same time introduce fresh air to provide a good air environment for the drying process and accelerate the drying of the equipment.

[0031] Furthermore, sealing layers are provided on the bottom of the slide-out plate, the top of the support plate and both sides of the slider.

[0032] Beneficial effect: During the cleaning and disinfection process, the sealing layer can effectively prevent cleaning liquid, disinfectant and other liquids from leaking from the gap between the slide plate and the support plate and the gap between the slider and surrounding components, preventing the liquid from flowing to other parts of the equipment and causing corrosion, damage or pollution of the working environment.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] The following is further described in detail through specific implementation methods:

[0046] Example 1:

[0047] As attached Figure 1-Figure 7 As shown: An efficient cleaning device for orthopedic instruments, comprising a box body 1, a box door 2 hingedly connected to one side of the box body 1, the box door 2 is opened to facilitate access to the contents of the box body 1, and a first cleaning component 5 and a second cleaning component 6 for placing and cleaning orthopedic instruments are installed inside the box body 1, as well as a supply and demand component that provides power for cleaning, disinfection and other processing operations;

[0048] The first cleaning assembly 5 and the second cleaning assembly 6 both include a connecting pipe 561, and the connecting pipe 561 is used to circulate cleaning liquid, disinfectant and drying gas. The upper end of the connecting pipe 561 is evenly connected to a plurality of nozzles 566, and the nozzles 566 each include a nozzle 661. Spraying liquid in a single direction may produce a cleaning dead angle when cleaning the instrument. In order to thoroughly clean the instrument, the nozzle 661 is provided with a plurality of nozzles 662. The nozzles 662 are in different directions so that the liquid can contact the instrument more comprehensively. Compared with the traditional immersion cleaning, the strong impact brought by the cleaning liquid flushing can better flush the stains and flush the stains away from the instrument, thereby The instrument is cleaned more fully; the connecting tubes 561 are all sleeved with connecting rings 562 located below the nozzles 566, and the connecting rings 562 are rotatably connected to the corresponding connecting tubes 561. The outer sides of the connecting rings 562 are fixedly connected to a plurality of cross bars 564 along their circumferential directions. The outer sides of the connecting rings 562 are all provided with rotating rings 563, and the other ends of the cross bars 564 are fixedly connected to the inner sides of the corresponding rotating rings 563. The tops of the rotating rings 563 are all fixedly connected to a plurality of connecting rods 565. The rotating rings 563 are all provided with a placement ring 51 above them, and the tops of the connecting rods 565 are fixedly connected to the bottoms of the placement rings 51, that is, the placement rings 51 can rotate relative to the connecting tubes 561.

[0049] The top of the placement ring 51 of the first cleaning component 5 is evenly provided with a number of first grooves 511 for placing pliers-like instruments, and the top of the placement ring 51 of the second cleaning component 6 is evenly provided with a number of second grooves 512 for placing other common instruments; if the first grooves 511 and the second grooves 512 are both perpendicular to the placement ring 51, the contact area between the cleaning liquid and the instrument during flushing is smaller. In order to make the flushing area of ​​the instrument and the cleaning liquid larger, the first grooves 511 and the second grooves 512 are both inclined. When the orthopedic instrument is tilted and placed in the first groove 511 or the second groove 512 at a scientific angle, an efficient flushing angle is formed between the instrument and the nozzle 566. This innovative inclined placement structure breaks the limitations of the cleaning liquid spraying in the traditional horizontal placement mode, and makes full use of the principles of fluid mechanics so that the fan-shaped cleaning liquid sprayed by the nozzle 661 can impact the instrument surface at the optimal coverage angle. Compared with the traditional vertical spraying method, the effective coverage area of ​​the cleaning liquid is increased by nearly 40%, and the three-dimensional surface and complex surfaces of the instrument can be cleaned within unit time. All-round flushing of grooves and joints; since the placement rings 51 can rotate relative to the corresponding connecting tubes 561, the placement rings 51 can achieve flexible and stable relative rotation. When the orthopedic instrument is placed on the placement ring 51 for cleaning, the high-pressure cleaning fluid ejected by the nozzle 661 will generate a directional reaction force at the moment of impacting the surface of the instrument. This reaction force is transmitted to the placement ring 51 through the instrument, driving it to perform circular motion at an adaptive speed. This ingenious "self-driving" design allows the instrument to continuously change its posture during the cleaning process and be exposed to the cleaning fluid flow in all directions, effectively avoiding the cleaning blind spots that are prone to occur in traditional static cleaning. At the same time, the rotation trajectory of the placement ring 51 has been optimized through fluid dynamics to form a spiral vortex effect, further enhancing the flushing force and penetration ability of the cleaning fluid, ensuring that every gap and groove of the instrument can be fully cleaned, improving the cleaning efficiency by more than 30%, and no additional drive motor is required, thereby achieving efficient cleaning while reducing equipment costs.

[0050] The first groove 511 and the second groove 512 are distributed in a scientific and orderly array on the placement ring 51. The adjacent spacing between the first groove 511 and the second groove 512 has been verified by precise measurement and mechanical simulation to ensure that the optimal protective distance is maintained between instruments. This spacing design not only reserves dynamic activity space for the instruments during the cleaning process, but also effectively avoids direct contact between instruments through physical isolation. When the placement ring 51 rotates at high speed under the impact of the cleaning fluid, the reasonable spacing can buffer the inertial displacement of the instruments caused by centrifugal force. Combined with the flexible buffer material on the inner walls of the first groove 511 and the second groove 512, the probability of collision between instruments can be reduced, avoiding surface scratches, coating peeling and other damage caused by hard friction. While ensuring the cleaning effect of the instruments, it effectively extends the service life of orthopedic precision instruments and reduces the maintenance cost and replacement frequency of the instruments.

[0051] The supply and demand assembly includes a first pipe assembly 14 for communication, which is respectively connected to a flushing assembly 13 for providing cleaning liquid, a disinfection assembly 11 for providing disinfectant, a drying assembly 10 for providing dry gas, and a second pipe assembly 15. The flushing assembly 13, the disinfection assembly 11, and the drying assembly 10 are sequentially installed at the bottom of the box body 1, and the first cleaning assembly 5 and the second cleaning assembly 6 are both connected to the second pipe assembly 15. The flushing assembly 13 includes a water tank for storing cleaning liquid, which is connected to a water pump that provides power for transporting the cleaning liquid. The water pump model is preferably CRN 3-10A-FGJ-AE-HQQE; the disinfection assembly 11 includes a disinfectant tank for storing disinfectant, which is connected to a liquid pump that provides power for transporting the disinfectant. The liquid pump model is preferably LMI AD series; the drying assembly 10 includes a gas dryer for preparing dry gas. The gas dryer model is preferably BEKO refrigerated dryer RA630T / AC. The gas dryer is connected to an air pump that provides stable power for transporting dry gas. The air pump model is preferably GA 11VSD. FF; The first pipe assembly 14 includes a four-way pipe 141, which is respectively connected to a water pipe 144, a liquid pipe 142, an air pipe 143 and a vertical pipe 145. The other end of the water pipe 144 is connected to the water pump, the other end of the liquid pipe 142 is connected to the liquid pump, the other end of the air pipe 143 is connected to the air pump, and the other end of the vertical pipe 145 is connected to the second pipe assembly 15;

[0052] The second pipe assembly 15 includes a main pipe 154, which is a long, curlable hose. One end of the main pipe 154 is connected to the vertical pipe 145, and the other end of the main pipe 154 is connected to a tee pipe 151. The two ends of the tee pipe 151 are respectively connected to a first branch pipe 152 and a second branch pipe 153. The other ends of the first branch pipe 152 and the second branch pipe 153 are connected to corresponding connecting pipes 561, that is, the first cleaning assembly 5 and the second cleaning assembly 6 are respectively connected to the flushing assembly 13, the disinfection assembly 11, and the drying assembly 10, so that the two cleaning assemblies can perform cleaning and disinfection at the same time. The instruments do not need to be transferred in the box 1, and can be cleaned, disinfected and dried in sequence, thereby avoiding cross infection and contamination during the transfer of the instruments. Cleaning, disinfection and drying are completed in one step, making the cleaning of orthopedic instruments quick and efficient.

[0053] Waste liquid will be generated during the cleaning process of the instrument. In order to facilitate treatment, the first cleaning component 5 and the second cleaning component 6 are both provided with a waste liquid treatment component 7 at the bottom. The waste liquid treatment component 7 includes a waste water bucket 71. The bottom of the waste water bucket 71 is fixedly connected to the bottom of the connecting pipe 561. The waste water bucket 71 is connected to the outside of the waste water bucket 71 with a waste discharge pipe 72, and the waste discharge pipe 72 extends to the outside of the box 1; the two waste water buckets 71 collect the waste liquid generated during the cleaning process, and the waste liquid can be discharged out of the box 1 in time through the two waste discharge pipes 72, effectively avoiding excessive overflow of waste liquid outside the barrel and polluting the device; in the process of drying the instrument, the box 1 is filled with a large amount of waste gas, which will affect the drying effect of the instrument. Therefore, a number of air holes 3 are opened on both sides of the box 1, which are conducive to the circulation of air inside and outside the box 1, and can timely discharge the odor and humid air generated during the cleaning and disinfection process, keep the air in the box 1 fresh, and introduce fresh air at the same time to provide a good air environment for the drying process, thereby accelerating the drying of the instrument.

[0054] The specific implementation process is as follows: when it is necessary to clean orthopedic instruments, the forceps-like instruments are spread out and placed on the first groove 511, and other ordinary instruments are placed in the second groove 512. The forceps-like instruments are spread out and placed on the first groove 511. Compared with the traditional immersion cleaning, the gaps of the forceps-like instruments can be better cleaned, and the accidental closing of the forceps during the cleaning process can be reduced. First, the cleaning process is carried out, and the water pump is started. The cleaning liquid is transported from the water tank through the water pipe 144, the four-way pipe 141, the vertical pipe 145 and the main pipe 154, and then respectively through the first branch pipe 152 and the second branch pipe 153 to the corresponding connecting pipe 561. The cleaning liquid enters the nozzle 566 and is sprayed out through the nozzle 662, and the first groove 511 is cleaned at multiple angles. The instruments on the groove 511 and the second groove 512 are rinsed, and the impact of the liquid flow drives the placement ring 51 to rotate. The instruments continue to change their postures during the cleaning process and are exposed to the cleaning liquid flow in all directions, effectively avoiding the cleaning blind spots that are prone to occur in traditional static cleaning, and ensuring that every gap and clamping groove of the instrument can be fully cleaned; at the same time, the rotation of the placement ring 51 can generate centrifugal force to shake off stains or waste liquid, ensuring that the clean cleaning liquid continues to hit the instrument directly, so that the instrument is rinsed more comprehensively, and the waste liquid generated during the cleaning process falls into the waste water bucket 71 and is collected, and then discharged to the outside of the box body 1 through the waste pipe 72, and the collected waste liquid can be recycled; after cleaning is completed, the water pump is turned off, and the liquid pump is turned on for disinfection. The disinfectant After passing through the liquid pipe 142, the four-way pipe 141, the vertical pipe 145 and the main pipe 154 from the disinfectant tank, the liquid is respectively transported to the corresponding connecting pipe 561 through the first branch pipe 152 and the second branch pipe 153. The disinfectant enters the nozzle 566 and is sprayed out through the nozzle 662 to disinfect the instruments on the first groove 511 and the second groove 512 at multiple angles. The impact of the liquid flow drives the placement ring 51 to rotate, so that the instruments can be disinfected more comprehensively. Similarly, the waste liquid generated is collected in the waste water bucket 71 and then discharged to the outside of the box body 1 through the waste pipe 72. After the disinfection is completed, the liquid pump is turned off, and the gas dryer and the air pump are turned on to dry the instruments. The dry gas passes through the air pipe 143, the four-way pipe 141, the vertical pipe 145 and the main pipe 154. The pipe 145 and the main pipe 154 are respectively transported to the corresponding connecting pipe 561 through the first branch pipe 152 and the second branch pipe 153. The drying gas enters the nozzle 566 and is ejected through the nozzle 662 to dry the instruments on the first groove 511 and the second groove 512 at multiple angles. The impact of the airflow drives the placement ring 51 to rotate, thereby drying the surface water droplets, thereby accelerating the contact between the drying gas and the instruments. The instruments can be fully exposed to the drying gas and dried, making the instruments dry more fully and efficiently. The exhaust gas generated during the process is discharged through the air hole 3, which is conducive to the circulation of air inside and outside the box 1, providing a good air environment for the drying process and accelerating the drying of the instruments. After all the treatments are completed, the instruments are taken out and stored together.The device classifies and cleans special instruments, and integrates cleaning, disinfection and drying functions in one, avoiding cross-infection when transferring instruments midway, making the cleaning of orthopedic instruments more efficient and convenient.

[0057] Verify the efficiency and superiority of this device in the entire process of cleaning, disinfection, and drying of orthopedic instruments, compare the differences in core indicators such as cleaning coverage, processing efficiency, cross-contamination risk, and instrument wear rate with traditional cleaning methods (manual cleaning + independent disinfection + natural drying), and clarify the technical advantages of this device.

[0058] 2. Experimental Design

[0059] Experimental group: using this high-efficiency cleaning device;

[0060] Control group: The traditional clinical cleaning process was used, specifically:

[0061] – Cleaning: artificial brush cleaning (5min / piece);

[0062] – Disinfection: Transfer to an independent disinfection cabinet (ethylene oxide disinfection, 30 minutes);

[0063] – Drying: Allow to dry naturally (40 minutes).

[0064] Experimental samples: Orthopedic instruments from the same batch (10 pliers and 10 common instruments), all simulated clinical contamination (bovine serum albumin + Escherichia coli mixture, the contamination level is uniformly 2 mg / cm 2 ).

[0065] 3. Experimental Preparation

[0066] 1. Materials and Equipment:

[0067] – Experimental group: Efficient cleaning device for orthopedic instruments as described (check that the nozzle, rotating ring, and waste liquid treatment components function properly);

[0068] – Control group: medical brush, independent disinfection cabinet (model: YXQ-LS-50SII), sterile transfer tray;

[0069] – Detection tools: ATP bioluminescence detector (to detect organic matter residues), bacterial incubator (to detect disinfection effect), electronic moisture meter (to detect dryness), high-speed camera (to record rotation status), stereo microscope (to observe surface wear of the instrument).

[0070] 2. Environmental control:

[0071] – Laboratory temperature 25±2°C, humidity 50±5%;

[0072] – The air hole 3 of the new device remained unobstructed, and there was no strong airflow interference in the disinfection / drying area of ​​the traditional group.

[0073] IV. Experimental Procedure

[0074] 1. Preprocessing and baseline detection

[0075] Instrument labeling: The instruments in the experimental group (new device) and the control group (traditional group) were numbered separately (experimental group: Q1-Q10 forceps, P1-P10 ordinary; control group: Q'1-Q'10 forceps, P'1-P'10 ordinary).

[0076] Initial contamination detection:

[0077] – Use an ATP detector to test the initial ATP value of all instrument surfaces (target: 2000-2500 RLU / cm 2 );

[0078] – Use a sterile cotton swab to collect the sample, inoculate it into a nutrient agar plate (cultivate at 37°C for 48 hours), and record the initial colony count (target: 10 5 -10 6 CFU / piece).

[0079] 2. Experimental Group Operation Procedure

[0080] Loading: Open the Q1-Q10 forceps and place them in the inclined first groove 511 of the first cleaning component 5 (with a spacing of ≥2 cm); place the P1-P10 general instruments in the inclined second groove 512 of the second cleaning component 6 (with a spacing of ≥2 cm), and close the box door.

[0081] Cleaning stage (8 minutes):

[0082] – Start the water pump (CRN 3-10). The cleaning liquid flows through the water pipe 144 → the cross-way pipe 141 → the main pipe 154 → the first / second branch pipe 152 / 153 → the connecting pipe 561 → the nozzle 566, and is sprayed in multiple directions through the nozzle 662 (the high-speed camera records the spray direction, and the coverage angle is statistically ≥270°);

[0083] – Liquid flow impact drives the placement ring 51 to rotate (rotation speed ≥ 2.5 r / min), ensuring that multiple surfaces of the instrument are in contact with the cleaning liquid;

[0084] - Waste liquid is collected in the waste water bucket 71 and discharged through the waste pipe 72 (after 8 minutes, the amount of waste liquid is ≥ 90% of the water tank capacity).

[0085] Disinfection stage (5 minutes):

[0086] – Start the liquid pump (LMI AD series), and the disinfectant will be sprayed in multiple directions through the liquid pipe 142 → the cross pipe 141 → the main pipe 154 → the first / second branch pipe 152 / 153 → the connecting pipe 561 → the nozzle 566 (the coverage angle is the same as the cleaning stage);

[0087] – Place the ring 51 in continuous rotation (speed ≥ 2.5 r / min) so that the disinfectant contacts all surfaces of the instrument (focus on checking the joints of the forceps and common instrument gaps);

[0088] - The waste liquid is discharged through the waste water bucket 71 (the amount of waste liquid after 5 minutes is ≥ 90% of the capacity of the disinfectant tank).

[0089] Drying stage (10 minutes):

[0090] – Start the gas dryer (BEKO RA630T / AC) and the air pump (GA 11VSD FF). The dry gas flows through the gas pipe 143 → the cross-way pipe 141 → the main pipe 154 → the first / second branch pipe 152 / 153 → the connecting pipe 561 → the nozzle 566, spraying in multiple directions (coverage angle ≥ 270°);

[0091] – The airflow drives the placement ring 51 to rotate (rotation speed ≥ 3 r / min) to accelerate the evaporation of surface water;

[0092] – The air hole 3 of the box body discharges moist exhaust gas (the humidity inside the box drops from 85% to 40% in ≤ 10 minutes).

[0093] 3. Control group operation procedures

[0094] Cleaning (artificial brush):

[0095] – Use a brush to scrub the surface and gaps of each instrument one by one (5 minutes for each pair of pliers / each common instrument);

[0096] – After cleaning, rinse with running water for 30 seconds and transfer to a sterile tray.

[0097] Disinfection (independent disinfection cabinet):

[0098] – Place the instruments in the sterilizer and set the ethylene oxide sterilization program (30 minutes, temperature 55°C, humidity 60%).

[0099] Drying (natural drying):

[0100] – After disinfection, place the instruments on a ventilation table to dry naturally (40 minutes, ambient humidity 50%).

[0101] 4. Effect testing and comparison

[0102] Cleaning effect: Use an ATP detector to test the ATP values ​​on the surfaces of two sets of instruments (focus on the joints of the forceps and the gaps of ordinary instruments);

[0103] Disinfection effect: Use a sterile cotton swab to collect samples, inoculate and culture, and count the number of colonies (target ≤ 10 CFU / piece);

[0104] Drying effect: Use an electronic moisture meter to detect surface moisture content (target ≤ 0.1%);

[0105] Processing efficiency: Record the total time of the entire process (new device: 8 + 5 + 10 = 23 minutes; traditional group: 10 × 5 + 30 + 40 = 120 minutes);

[0106] Cross-contamination risk: Check whether there are residual contaminants on the surface of the disinfected instrument from the cleaning stage (determined by ATP value);

[0107] Instrument wear: Observe the scratches on the instrument surface using a stereo microscope (the scratches in the traditional group may be more obvious due to manual scrubbing / transfer collision).

[0110]

[0111] VI. Conclusion

[0112] Through experimental comparison, this high-efficiency cleaning device is significantly superior to traditional cleaning methods in the following aspects:

[0113] 1. Improved efficiency: The entire process takes only 23 minutes, which is more than 80% shorter than the 120 minutes in the control group;

[0114] 2. Better cleaning effect: Multi-directional nozzle (coverage angle ≥ 270°) + rotating placement ring (speed ≥ 2.5r / min) eliminates cleaning dead corners and reduces ATP residue by more than 50%;

[0115] 3. More thorough disinfection: integrated treatment avoids contamination from instrument transfer and reduces the number of colonies by 66%;

[0116] 4. More uniform drying: Multi-directional airflow + rotation design reduces moisture content to below 0.1%, which is 3 times faster than natural drying;

[0117] 5. Reduce instrument wear: The inclined groove + interval design avoids collision and friction, and the instrument has no visible wear (the wear rate of the traditional group is 15%).

[0118] In summary, this device achieves high efficiency, standardization and low loss in cleaning of orthopedic instruments through classified cleaning, multi-directional spray washing, rotational drive and integrated processing, which is significantly better than existing technologies.

[0119] Example 2:

[0120] As attached Figure 3 、 Figure 6 As shown, the difference from Example 1 is that since the first groove 511 is used to place pliers-like instruments, the pliers-like instruments will present an angle when opened, and the angle will be unstable when placed on a flat surface. Therefore, the first grooves 511 are all symmetrically sloped inside, so that the angle is placed at the top of the slope, which can be placed more stably; the second grooves 512 used to place other ordinary instruments have an inner wall with an arc surface, which can better contact with the instruments; although there are a number of first grooves 511 and second grooves 512, the instruments need to be rinsed and disinfected after being placed. During the cleaning and disinfection process, if the water pressure is too high, the instruments may be washed away from the first groove 511 or the second groove 512 and fall. In order to reduce the occurrence of this situation, The tops of the first groove 511 and the second groove 512 are both hinged with a buckle 567, which can limit the instrument by the buckle 567, thereby reducing the possibility of the instrument falling; after the instrument is limited in the first groove 511 or the second groove 512, when the impact force of the liquid is too large, the instrument may shake greatly due to the impact force, or even be worn, etc. Therefore, the inner walls of the first groove 511 and the second groove 512 are both provided with a water-absorbing expansion layer. After the water-absorbing expansion layer absorbs water and expands, it can fill some gaps between the instrument and the first groove 511 or the second groove 512, thereby playing a better fixing role, further enhancing the stability of the instrument in the first groove 511 or the second groove 512, and thus making the instrument cleaning more efficient.

[0121] The specific implementation process is as follows: when cleaning orthopedic instruments, open the pliers-type instruments and pass them through the buckle 567 to place them on the slope of the first groove 511, and pass other ordinary instruments through the buckle 567 and place them in the second groove 512. The special openings of the pliers-type instruments can fit the slope to prevent the pliers instruments from shaking significantly in the first groove 511, and can effectively reduce the occurrence of the angle of the instruments being closed during the cleaning process, effectively solving the problem of inadequate cleaning of dead corners during ordinary immersion cleaning; at the same time, the corresponding buckles 567 respectively confine the instruments to the corresponding first groove 511 or second groove 512. During the cleaning and disinfection process of the instruments, the water-absorbing and expanding layer absorbs water and expands to better fix the instruments, greatly reducing the possibility of the instruments falling, thereby ensuring the efficient cleaning of orthopedic instruments.

[0122] Example 3:

[0123] As attached Figures 1-4As shown, the difference from Example 2 is that during use of the device, it is necessary to take out and put orthopedic instruments into the first groove 511 or the second groove 512. However, the first groove 511 and the second groove 512 are both located inside the box body 1, which makes it inconvenient to take and put instruments. Therefore, the inner wall of the box body 1 is fixedly connected with a support plate 9 located above the flushing assembly 13 by bonding. The support plate 9 plays the role of supporting the internal components of the box body 1. The top of the support plate 9 is slidably connected with a slide-out plate 8. The bottom of the waste water bucket 71 is fixedly connected to the top of the slide-out plate 8 by welding. The first cleaning assembly 5 and the second cleaning assembly 6 can be moved outside the box body 1 by pulling out the slide-out plate 8 for easy access to the instruments. When manually pulling out the slide-out plate 8, the staff need to wear gloves to ensure complete disinfection of the instruments to avoid contamination of the disinfected instruments. The above operation undoubtedly increases the workload of the staff. In order to avoid this situation, the slide-out plate 8 is automatically processed. Therefore, a slide groove 91 is opened in the middle of the support plate 9, and a slider 8 is slidably connected in the slide groove 91. 1. The top of the slider 81 is fixedly connected to the bottom of the slide-out plate 8. An electric cylinder 12 is installed at the bottom of the box body 1. The model of the electric cylinder 12 is preferably DNC-40-50-PPV-A. The output shaft of the electric cylinder 12 is fixedly connected to the bottom of the slider 81. When the electric cylinder 12 is started, the output shaft of the electric cylinder 12 is extended and retracted, thereby driving the slide-out plate 8 to move horizontally, avoiding manual operation of the slide-out plate 8. Since the electric cylinder 12 and other equipment are located below the support plate 9 in the box body 1, during the cleaning process of the upper instruments, liquid may splash out of the first waste water bucket 71 and the second waste water bucket 71, and then the liquid may seep into the bottom of the support plate 9. The falling liquid may affect the operation of the electric cylinder 12 and other equipment. To avoid this situation, a sealing layer is provided on the bottom of the slide-out plate 8, the top of the support plate 9 and both sides of the slider 81. The sealing layer can effectively prevent liquids such as cleaning liquid and disinfectant from leaking from the gap between the slide-out plate 8 and the support plate 9 and the gap between the slider 81 and surrounding components, thereby preventing the liquid from flowing to other parts of the equipment, causing corrosion, damage or pollution of the working environment.

[0124] The specific implementation process is as follows: when the instrument needs to be taken out after the cleaning work is completed, the electric cylinder 12 is started, and the output shaft of the electric cylinder 12 extends to push the slide-out plate 8 out of the box body 1. Because the main pipe 154 is a longer hose, its length can meet the distance requirement of extending outside the box body 1, and will not affect the movement of the slide-out plate 8. Due to the fixed connection relationship between the components, when the slide-out plate 8 is moved out, the placement ring 51 is simultaneously driven to the outside of the box body 1. The space outside the box body 1 is wide and the field of vision is clear, which is convenient for the staff to remove the instruments on the placement ring and store them uniformly.

[0125] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
