Description

Technical Field

[0001] This invention relates to the field of disinfection device technology, specifically to a shipborne portable surgical instrument cleaning and disinfection device and its usage method. Background Technology

[0002] In scenarios such as field rescue, ship navigation, disaster emergency response, and medical support in remote areas, surgical instruments must be cleaned, disinfected, and dried promptly and thoroughly after use to remove residual bloodstains, tissue debris, body fluids, and other contaminants from the instrument surface, kill pathogenic microorganisms, and avoid intraoperative cross-infection and postoperative complications.

[0003] Currently, the traditional method for handling portable or on-site surgical instruments still primarily involves immersion in disinfectant solutions. This method relies solely on the chemical action of the disinfectant to passively disinfect the instrument surface, failing to effectively remove stubborn dirt and biofilm from instrument joint crevices, grooves, and internal lumens, resulting in poor cleaning effectiveness and low cleanliness. Furthermore, immersion disinfection suffers from problems such as long disinfection times, easy degradation of disinfectant concentration, cross-contamination between different instruments, and difficulties in waste disposal.

[0004] In the unique environment of a ship, limited space, swaying sea surface, high salinity and humidity, and limited freshwater and power supplies make traditional immersion methods insufficient to meet the demands for rapid, efficient, and stable disinfection. Furthermore, cleaning wastewater containing pathogenic microorganisms cannot be directly discharged, posing significant environmental pollution and biosafety risks. Existing equipment struggles to achieve an effective balance between portability, low energy consumption, high-efficiency disinfection, shipboard adaptability, and wastewater self-circulation, failing to meet the safe handling requirements of surgical instruments in special scenarios such as fieldwork and shipboard operations.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a shipborne portable surgical instrument cleaning and disinfection device, including a disinfection box 1. A disinfection layer 2 is slidably disposed inside the disinfection box 1, and a disinfection groove is formed on the surface of the disinfection layer 2. A cleaning basket 3 is placed inside the disinfection groove. A disinfection assembly 4 is installed inside the disinfection box 1. The disinfection assembly 4 includes a miniature ultrasonic transducer 401 and an electric pusher cylinder 402. The miniature ultrasonic transducer 401 is fixed to the inner bottom of the disinfection layer 2 by bolts and can be disassembled and replaced. The electric pusher cylinder 402 is fixedly installed in the disinfection box 1. At the top inner part, the drive end of the electric push cylinder 402 is fixedly provided with a mounting base 403. The bottom of the mounting base 403 is provided with an inlet pipe 404. The outer wall of the inlet pipe 404 is penetrated from top to bottom by a baffle 405 and a rotating arm 406. The rotating arm 406 is fixedly connected to the inlet pipe 404. Several nozzles 407 are fixedly provided at the bottom of the rotating arm 406. A flow channel is provided inside the rotating arm 406 for connecting the nozzles 407 and the inlet pipe 404. A rotating mechanism 408 is installed on the mounting base 403 for driving the inlet pipe 404 to rotate.

[0024] Specifically, during use, first pull out the disinfection layer 2, place the surgical instruments on the cleaning basket 3, then place the cleaning basket 3 into the disinfection tank, and then push in the disinfection layer 2. The electric push cylinder 402 drives the liquid inlet pipe 404 to extend, causing the baffle 405 to descend and cover the disinfection tank, preventing liquid from splashing out during cleaning and also limiting the position of the disinfection layer 2. Disinfectant is injected through the liquid inlet pipe 404, and the disinfectant is sprayed out through the nozzle 407 to rinse and disinfect the surgical instruments on the cleaning basket 3 below. The rotating mechanism 408 drives the rotating arm 406 to rotate, so that the nozzle 407 rotates 360° to rinse the surgical instruments without dead angles, thereby improving the rinsing and disinfection effect of the surgical instruments. During rinsing, the micro ultrasonic transducer 401 uses the cavitation effect to efficiently remove stubborn dirt from the joints and teeth of the instruments.

[0025] Please see the appendix Figure 5 The rotating mechanism 408 includes a motor 4081, which is fixedly installed at the bottom of the mounting base 403. A gear 4082 is fixedly installed at the drive end of the motor 4081. The gear 4082 is meshed with a gear ring 4083, and the gear ring 4083 is fixedly installed on the outside of the liquid inlet pipe 404.

[0026] Specifically, the motor 4081 drives the gear 4082 to rotate, the gear 4082 drives the gear ring 4083 to rotate, and the gear ring 4083 drives the inlet pipe 404 to rotate, so that the nozzle 407 can produce a rotating spray disinfection function.

[0027] Please see the appendix Figure 6 The baffle 405 is rotatably connected to the inlet pipe 404, and a telescopic rod 409 is fixed between the baffle 405 and the disinfection box 1. A toothed ring 410 is rotatably connected to the bottom of the baffle 405. A gear 411 is meshed with the inner side of the toothed ring 410. A toothed ring 412 is meshed with the gear 411. The toothed ring 412 is fixedly installed on the outer wall of the inlet pipe 404. A horizontally arranged telescopic elastic rod 413 is fixed on the outer wall of the toothed ring 410. The elastic rod 413 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is sleeved in the area of ​​the inner rod inside the outer cylinder to keep the inner rod retracted inside the outer cylinder. Several connecting grooves 414 are opened on the inner side wall of the cleaning basket 3.

[0028] Specifically, the telescopic rod 409 is used to guide the baffle 405 vertically. When the inlet pipe 404 rotates, it drives the gear ring 3 412 to rotate forward. The gear ring 3 412 drives the gear 2 411 to rotate in reverse. The gear 2 411 drives the gear ring 2 410 to rotate in reverse. The centrifugal force generated when the gear ring 2 410 rotates keeps the elastic rod 413 extended and against the inner wall of the cleaning basket 3. When the elastic rod 413 rotates to the connecting groove 414, the elastic rod 413 continues to extend and inserts into the connecting groove 414, thereby driving the cleaning basket 3 to rotate in the opposite direction to the nozzle 1 407. The nozzle 1 407 rotates forward to provide a directional high-pressure water flow. The cleaning basket 3 rotates in reverse to make the instrument continuously change the angle of impact, forming a two-way relative motion, which can significantly improve the efficiency of dirt removal.

[0029] Please see the appendix Figure 6 - Appendix Figure 7 The bottom end of the inlet pipe 404 passes through the rotating arm 406. An inlet head 415 is inserted into the bottom end of the inlet pipe 404. The bottom end of the inlet head 415 is fixedly connected to the disinfection layer 2. A fixing arm 416 is fixedly provided on the outer wall of the inlet head 415. Several nozzles 417 are fixedly provided on the top of the fixing arm 416. A flow channel is also provided inside the fixing arm 416 to connect the nozzles 417 and the inlet pipe 404.

[0030] Specifically, when the inlet pipe 404 descends, its bottom end engages with the inlet head 415, allowing the disinfectant in the inlet pipe 404 to be sprayed upwards from the nozzle 417. Combined with the rotating cleaning basket 3, the surgical instruments can be rinsed from bottom to top 360°. The two-way rotating rinsing formed by the nozzles 407 and 417 further enhances the cleaning effect on the surgical instruments.

[0031] Please see the appendix Figure 8 The bottom of the cleaning basket 3 is rotatably connected to a rotating ring 418. Several slots are opened on the surface of the rotating ring 418, and partition plates 419 are inserted into the slots. A limiting block 420 is fixed on the inner side wall of the rotating ring 418. A limiting post 421 is set inside the rotating ring 418, and the bottom end of the limiting post 421 is fixedly connected to the disinfection layer 2.

[0032] Specifically, the cleaning basket 3 is divided into different storage spaces by the partition plate 419 for the classified placement of surgical instruments. The partition plate 419 can be flexibly added or removed. When the cleaning basket 3 rotates, the limiting block 420 is restricted by the limiting post 421, which can intercept the rotating ring 418, so that the partition plate 419 remains stationary relative to the cleaning basket 3. This adjusts the relative position of the hole at the bottom of the cleaning basket 3 and the surgical instruments, allowing the disinfectant to be more thoroughly rinsed to the bottom area of ​​the surgical instruments through the hole, thereby improving the cleaning range and cleaning effect.

[0033] Please see the appendix Figure 9 - Appendix Figure 10The disinfection box 1 has a cabinet door 5 hinged to its lower side. A waste liquid tank 6 and a disinfection liquid tank 7 are inserted into the interior of the disinfection box 1. A dryer 8 is fixed inside the disinfection box 1. A pump body 9 is fixed to the top of the disinfection liquid tank 7, with the inlet end of the pump body 9 extending to the bottom of the disinfection liquid tank 7. The inlet pipe 404 includes an upper pipe body 4041 and a lower pipe body 4042 rotatably connected. The upper pipe body 4041 is fixedly connected to the mounting base 403, while the lower pipe body 4042 is connected to a gear ring 4083 for rotation. A conveying pipe 10 is fixed to the side wall of the upper pipe body 4041. Two branch pipes 11 are provided at the lower end of the conveying pipe 10, and each branch pipe 11 has a valve connected to the air outlet of the dryer 8 and the liquid outlet of the pump body 9, respectively. A heater is fixed to the bottom of the disinfection liquid tank 7. The device 8 includes a built-in high-efficiency particulate air (HEPA) filter 13, a miniature high-efficiency centrifugal fan for drawing in clean air, and a heating element. The top of the disinfectant tank 7 is equipped with a filling port with a sealed cap, through which disinfectant and clean water are added. The disinfectant tank 7 also has a built-in concentration sensor for detecting the concentration of the disinfectant and a level sensor for detecting the water level. When the concentration of the disinfectant or the water level is insufficient, it will remind the staff to add disinfectant. The disinfectant tank 7 also has a built-in temperature sensor for detecting the heating temperature of the disinfectant. Both the waste tank 6 and the disinfectant tank 7 are quick-connect designs for easy replacement. The disinfectant tank 7 is used to store the disinfectant solution formed by the mixed disinfectant and clean water. The capacity of the waste tank 6 and the disinfectant tank 7 can be set to 3-5 liters.

[0034] Specifically, during cleaning, the valve on the branch pipe 11 connecting to the dryer 8 is closed, and the valve on the branch pipe 11 connecting to the pump body 9 is opened. The pump body 9 draws the disinfectant stored in the disinfectant tank 7 and enters the inlet pipe 404 through the branch pipe 11 and the delivery pipe 10. A high-pressure jet is then formed at the nozzles 407 and 417 for rinsing. The disinfectant in the disinfectant tank 7 is preheated to above 90°C by a heater. The high-temperature hot water spray (above 90°C) lasts for 5 minutes, achieving a disinfection Ao value of [value missing]. The concentration reaches 3000, which is a high-level disinfection stage. The high-level disinfection meets the standards for use of medium-risk items, thereby improving the disinfection effect on surgical instruments. After rinsing, the valve on the branch pipe 11 connected to the dryer 8 is opened and the valve on the branch pipe 11 connected to the pump body 9 is closed. At this time, heat flow is generated through the dryer 8 and enters the inlet pipe 404 through the branch pipe 11 and the delivery pipe 10. Then, hot air is generated at the nozzle 407 and the nozzle 417 to quickly dry the surface moisture of the instruments and prevent secondary pollution and corrosion.

[0035] Please see the appendix Figure 10The bottom of the disinfection layer 2 is equipped with a drain end 12 with a valve. The drain end 12 is connected to the waste liquid tank 6 through a hose. The bottom of the waste liquid tank 6 is equipped with a filter 13 with a valve. The filter 13 is connected to the disinfection liquid tank 7 through a hose. The filter 13 is fixed by bolts or threads, which facilitates the replacement of the filter element inside the filter 13. The filter 13 performs deep purification on the pre-disinfected cleaning wastewater, intercepting bacteria, viruses and tiny suspended solids.

[0036] Specifically, the waste liquid in the disinfection tank is discharged into the waste liquid tank 6 through the drain end 12 and the hose for disinfection. After disinfection, it is filtered through the filter 13 and then flows into the disinfection liquid tank 7 for recycling, realizing the filtration and recycling of the disinfection liquid for cleaning, which greatly extends the working time in waterless areas.

[0037] Please see the appendix Figure 10 - Appendix Figure 11 The waste liquid tank 6 is provided with a feeding assembly 14 on the top. The feeding assembly 14 includes a storage chamber 1401 for storing disinfectant tablets. The storage chamber 1401 is fixed on the top of the waste liquid tank 6. A sliding plate 1402 is provided below the storage chamber 1401. A storage opening 1403 is opened on the surface of the sliding plate 1402. An elastic reset member 1405 is fixed between the sliding plate 1402 and the inner wall of the waste liquid tank 6. An intercepting plate 1404 is provided below the sliding plate 1402. The intercepting plate 1404 is fixed on the inner top wall of the waste liquid tank 6. The diameter of the storage chamber 1401 and the storage opening 1403 is larger than the diameter of the disinfectant tablets. The depth of the storage opening 1403 is set according to the different contents of the waste liquid tank 6 and the number of disinfectant tablets required at one time.

[0038] Specifically, disinfectant tablets are placed in the storage chamber 1401. The disinfectant tablets below are fed into the storage port 1403 and blocked by the intercepting plate 1404. When disinfecting the waste liquid in the waste liquid tank 6, the sliding plate 1402 is pushed to slide, so that the storage port 1403 is misaligned with the intercepting plate 1404, so that the disinfectant tablets stored in the storage port 1403 fall into the waste liquid tank 6 for disinfection. After the sliding plate 1402 is released, the sliding plate 1402 is reset by the elastic reset member 1405, so that the storage port 1403 moves again to directly below the storage chamber 1401, so that the disinfectant tablets fall into the storage port 1403 again.

[0039] Please see the appendix Figure 11 A piston chamber 15 is fixedly provided on the upper side wall of the waste liquid tank 6. One end of the piston chamber 15 is connected to the waste liquid tank 6 through an air inlet pipe. A piston block 16 is slidably provided inside the piston chamber 15. A connecting rod 17 is fixed between the piston block 16 and the slide plate 1402, and the connecting rod 17 passes through the waste liquid tank 6. An exhaust end 18 is provided on the top of the piston chamber 15.

[0040] Specifically, during the drying process, the airflow inside the disinfection tank enters the waste liquid tank 6, then enters the piston chamber 15 through the air inlet pipe, and is pushed by the air pressure to move the piston block 16 to the rear of the exhaust end 18, thereby expelling the airflow. When the piston block 16 moves, it pushes the slide plate 1402 to move through the connecting rod 17. When the slide plate 1402 moves, the disinfection tablets stored in the storage port 1403 fall into the waste liquid tank 6 for disinfection, thereby achieving the effect of automatic feeding of disinfection tablets without the need for manual feeding.

[0041] The inventions mentioned above all employ electric valves, such as solenoid valves.

[0042] Please see the appendix Figure 1 - Appendix Figure 2 The disinfection box 1 is powered by a built-in high-energy-density lithium-ion battery pack, which is compatible with 220VAC and 24V / 12VDC (shipboard / vehicle-mounted power supply) inputs and can be extended to connect to a solar charging panel. The disinfection box 1 can be made of carbon fiber reinforced composite material and aerospace aluminum alloy, which can reduce weight while ensuring strength and three-proof (waterproof, dustproof, shockproof) performance. The top of the disinfection box 1 is embedded with a retractable railing, and the bottom of the disinfection box 1 is equipped with universal wheels with brakes. The rear side of the disinfection box 1 has a hidden carrying strap attachment point, which can be equipped with a special carrying strap for easy carrying by a single soldier. The left and right sides of the disinfection box 1 have tethering points for easy fixation inside the ship. The front of the disinfection box 1 is equipped with a waterproof capacitive touch screen with a graphical interface and clear process, which supports operation while wearing gloves, and has a physical emergency stop button. The waterproof capacitive touch screen, electric propulsion cylinder 402, sensor and motor 4081 are electrically connected to the controller. The sensor detection data is displayed on the waterproof capacitive touch screen for the operator to view.

[0043] The working principle is as follows: surgical instruments are placed on the cleaning basket 3, and then the cleaning basket 3 is placed in the disinfection tank. The electric push cylinder 402 drives the liquid inlet pipe 404 to extend, causing the baffle 405 to descend and cover the disinfection tank, preventing liquid from splashing out during cleaning. At the same time, it also serves to limit the disinfection layer 2. Disinfectant is injected through the liquid inlet pipe 404, and the disinfectant is sprayed out through the nozzle 407 to rinse and disinfect the surgical instruments on the cleaning basket 3 below. The rotating mechanism 408 drives the rotating arm 406 to rotate, so that the nozzle 407 rotates 360° to rinse the surgical instruments without dead angles, thereby improving the rinsing and disinfection effect of the surgical instruments.

[0044] When the inlet pipe 404 rotates, it drives the gear ring 412 to rotate forward. The gear ring 412 drives the gear 411 to rotate in reverse. The gear 411 drives the gear ring 410 to rotate in reverse. The centrifugal force generated when the gear ring 410 rotates keeps the elastic rod 413 extended and against the inner wall of the cleaning basket 3. When the elastic rod 413 rotates to the connecting groove 414, the elastic rod 413 continues to extend and inserts into the connecting groove 414, thereby driving the cleaning basket 3 to rotate in the opposite direction to the nozzle 407. The nozzle 407 rotates forward to provide a directional high-pressure water flow. The cleaning basket 3 rotates in reverse so that the instrument continuously changes the angle of impact, forming a bidirectional relative motion, which can significantly improve the efficiency of dirt removal.

[0045] When the inlet pipe 404 descends, its bottom end engages with the inlet head 415, allowing the disinfectant in the inlet pipe 404 to be sprayed upwards from the nozzle 417. Combined with the rotating cleaning basket 3, the surgical instruments can be rinsed from bottom to top 360°. The two-way rotating rinsing formed by the nozzles 407 and 417 further enhances the cleaning effect on the surgical instruments.

[0046] After rinsing, open the valve on the branch pipe 11 connecting to the dryer 8 and close the valve on the branch pipe 11 connecting to the pump body 9. At this time, heat is generated through the dryer 8 and enters the inlet pipe 404 through the branch pipe 11 and the delivery pipe 10. Then, hot air is generated from the nozzle 407 and the nozzle 417 to quickly dry the surface moisture of the instruments and prevent secondary pollution and corrosion. At the same time, the waste liquid in the disinfection tank is discharged into the waste liquid tank 6 through the drain end 12 and the hose for disinfection. After disinfection, it is filtered through the filter 13 and flows into the disinfection liquid tank 7 for recycling, realizing the filtration and recycling of the disinfection liquid for cleaning, which greatly extends the working time in waterless areas.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
