Abstract
Description
Technical Field
[0001] This application relates to the field of medical device cleaning technology, and more particularly to a disinfection and cleaning device for medical devices. Background Technology
[0002] Surgical instruments refer to medical devices used in clinical surgery. Generally, when cleaning scalpels, various utensils, and other metal surgical instruments, operators usually put them into a surgical instrument cleaning machine to remove bloodstains or impurities.
[0003] In the current cleaning process of medical devices, pre-cleaning is usually performed. After pre-cleaning, the pre-cleaned medical devices are placed in an ultrasonic cleaner for further cleaning. In the pre-cleaning of medical devices, they are mostly placed in water and then scrubbed by medical staff. During this process, the medical devices are in semi-flowing or still water, and the water flow has difficulty penetrating dried or solidified organic matter. This requires more manpower to scrub. When the scrubbing difficulty increases, the mechanical energy of scrubbing may damage the surface smoothness of the medical devices, affecting their service life. It can also easily lead to the presence of bacteria in the crevices, posing a safety hazard to surgical patients, and reducing the cleaning efficiency of the medical devices. Summary of the Invention
[0004] This application proposes a disinfection and cleaning device for medical devices, which has the advantage of better cleaning effect, in order to solve the problem that pre-cleaning water flow is difficult to penetrate dried or solidified organic matter.
[0005] To achieve the above objectives, this application adopts the following technical solution: a disinfection and cleaning device for medical devices, including a cleaning box, wherein a cover is movably sleeved on the top of the cleaning box, and a handle is fixedly connected to one side of the top of the cover; A water pump is fixedly connected to one side of the inside of the cleaning tank, and a circulation component is provided on the top of the water pump. A drive motor is fixedly connected to the middle of the upper surface of the cover, and a cleaning component is provided at the bottom of the drive motor; Preferably, an installation block is fixedly connected inside the cleaning box, and a cleaning chamber is fixedly connected to the top of the installation block. The cleaning chamber is equipped with a placement component. By placing the medical device inside the cleaning chamber, water flow is used to soften and clean the stains adhering to the surface of the medical device.
[0006] Preferably, the circulation assembly includes an inlet pipe fixedly connected to one side of the water pump and fixedly connected to the cleaning tank. An outlet pipe is fixedly connected to the top of the water pump and extends into the interior of the cleaning chamber. An outlet pipe is fixedly connected to the middle of the lower surface of the cleaning chamber and fixedly connected to the cleaning tank. The circulation assembly transforms the static water flow into a rapid vortex flow, thereby softening and cleaning the stains on the surgical instruments.
[0007] Preferably, the cleaning assembly includes a rotating shaft, which is fixedly connected to the output end of a drive motor. The bottom of the rotating shaft abuts against a first rotating rod. A fixed connecting rod is movably sleeved on the outer side of the bottom of the first rotating rod. The fixed connecting rod is fixedly connected to a cleaning tank. Multiple sets of limiting balls are movably sleeved inside the top of the first rotating rod. Multiple sets of limiting grooves are opened at the bottom of the rotating shaft. A guide groove is opened between two sets of limiting grooves. The limiting grooves are connected to each other through the guide groove. The medical device is brushed and cleaned by activating the cleaning assembly.
[0008] Preferably, the cleaning assembly further includes multiple sets of first sliding grooves, each set of first sliding grooves being formed on the outside of the first rotating rod, each set of first rotating rods being slidably connected to a second rotating rod inside, and each set of second rotating rods having a soft brush fixedly connected to one side of its bottom.
[0009] Preferably, the placement component includes two sets of second sliding grooves, which are respectively opened on both sides of the inside of the cleaning tank. Multiple sets of cleaning plates are slidably connected inside the second sliding grooves. Multiple sets of water guiding holes are opened inside the cleaning plates. Multiple sets of water guiding holes are fixedly connected to the top of each cleaning plate. Multiple sets of limiting blocks are fixedly connected to the top of the cleaning plate. By placing the cleaning component on the surface of the placement component, subsequent softening and cleaning are facilitated.
[0010] Preferably, the multiple sets of water guide holes are arranged in a ring, and the multiple sets of limiting blocks are arranged in a ring. The ring arrangement allows the medical device to be placed better and the space to be used more rationally.
[0011] Preferably, all of the multiple sets of cleaning plates are rotatably connected to the first rotating rod. The rotatable connection between the cleaning plates and the first rotating rod ensures that the cleaning assembly does not affect the cleaning plates when rotating, thereby cleaning the medical device.
[0012] Preferably, the outlet of the output pipe is tangent to the axis of the cleaning chamber, and the output pipe is located below the fixed connecting rod and the two do not contact each other. The tangency between the outlet of the output pipe and the axis of the cleaning chamber gives the water flow inside the cleaning chamber a driving force, causing the water flow to rotate along the inner wall of the cleaning chamber, so that the water flow inside the cleaning chamber circulates.
[0013] Preferably, the length of the multiple sets of second rotating rods is shorter than the inner diameter of the cleaning chamber, the height between the bottom surface of the second rotating rod and the top surface of the cleaning plate is 3cm, the length of the soft brush is 2cm, and the height of the limiting block and the limiting post is 2cm. By setting the length of the soft brush, the soft brush can extend into the interior of the limiting post and the limiting block to contact the limiting post and the limiting block, thereby preventing impurities washed off from adhering to the surface of the limiting post and the limiting block and causing unnecessary corrosion.
[0014] Preferably, the inside of the guide groove is inclined, and the width of the guide groove is equal to the diameter of the limiting ball. The inclined arrangement inside the guide groove causes the rotating shaft to contact the limiting ball after being pressed down, thereby driving the first rotating rod to move along the inclined groove of the guide groove, so that the limiting ball moves into the inside of the limiting groove to complete the engagement.
[0015] The beneficial effects of this invention are as follows: This invention uses a water pump to draw water into the cleaning chamber through inlet and outlet pipes. The water flows out along a point tangential to the axis of the cleaning chamber, giving the water inside the chamber a driving force that causes it to flow in a circular pattern. This creates vortices within the chamber, and the rotational kinetic energy of these vortices generates tangential shearing force. Over time, the water penetrates into organic matter (such as blood clots, proteins, and fats) adhering to the surface of medical devices, softening the dried or solidified organic contaminants. The rotating water flow then removes these contaminants from the surface of the medical devices, reducing the initial bacterial load before disinfection, decreasing the resistance of disinfectants to penetrating the biofilm, reducing the difficulty of sterilization, and improving the cleaning effect.
[0016] In this invention, since both the second rotating rod and the cleaning plate are detachable structures, they can be completely separated, avoiding the gaps or overlapping parts in traditional fixed structures, ensuring that cleaning and disinfection are thorough and without blind spots. Furthermore, the second rotating rod and the cleaning plate can be quickly and individually replaced after damage or wear, reducing costs. In addition, the detachable structure can further reduce biofilm or organic residues, making it particularly suitable for the pretreatment of stubborn contaminants such as blood stains and proteins, ensuring the hygiene and safety of medical devices.
[0017] This invention uses a drive motor to rotate a shaft and a first rotating rod. The rotation of the first rotating rod then drives a second rotating rod and a soft brush to rotate, thus brushing the medical devices placed on the cleaning plate surface. This provides a secondary cleaning of the organic matter attached to the surface. The initial use of the water flow's vortex effect may leave blind spots due to insufficient force. The secondary cleaning can target and reinforce these areas, ensuring no residue remains and improving the cleaning effect. Furthermore, by cooperating with the circulation component, pre-wetting and softening the surface reduces brushing resistance and extends the lifespan of the devices. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0022] Please see Figure 1-7 This invention provides a disinfection and cleaning device for medical devices, including a cleaning box 1, a cover 2 movably fitted on the top of the cleaning box 1, and a handle 3 fixedly connected to one side of the top of the cover 2. A water pump 4 is fixedly connected to one side inside the cleaning tank 1, and a circulation component is provided on the top of the water pump 4. A drive motor 9 is fixedly connected to the middle of the upper surface of the cover 2, and a cleaning component is provided at the bottom of the drive motor 9; The cleaning box 1 is fixedly connected to the mounting block 7, and the top of the mounting block 7 is fixedly connected to the cleaning chamber 8. The cleaning chamber 8 is equipped with a placement component. By placing the medical device inside the cleaning chamber 8, the stains adhering to the surface of the medical device are softened by the water flow, and then the cleaning component drives the second rotating rod 17 and the soft brush 18 to rotate and clean the stains.
[0023] The circulation component includes an inlet pipe 5, which is fixedly connected to one side of the water pump 4 and to the cleaning tank 1. An outlet pipe 6 is fixedly connected to the top of the water pump 4 and extends into the interior of the cleaning chamber 8. An outlet pipe 24 is fixedly connected to the middle of the lower surface of the cleaning chamber 8 and to the cleaning tank 1. By starting the water pump 4, water is drawn into the interior of the cleaning chamber 8 through the inlet pipe 5 and the outlet pipe 6. The water flows out along the axis tangential to the cleaning chamber 8, giving the water flow inside the cleaning chamber 8 a driving force, causing the water flow inside the cleaning chamber 8 to flow in a ring shape, thereby generating a vortex inside the cleaning chamber 8. The rotational kinetic energy of the vortex generates tangential shear force. Over time, the water flow penetrates into the organic matter adhering to the surface of the medical device, such as blood clots, proteins, and fats, softening the dried or cross-linked contaminants. The rotating water flow then removes these contaminants from the surface of the medical device, reducing the initial bacterial load before disinfection, reducing the resistance of the disinfectant to penetrate the biofilm, reducing the difficulty of sterilization, and improving the cleaning effect.
[0024] The cleaning component includes a rotating shaft 10, which is fixedly connected to the output end of a drive motor 9. A first rotating rod 11 abuts against the bottom of the rotating shaft 10. A fixed connecting rod 12 is movably sleeved on the outer side of the bottom of the first rotating rod 11 and is fixedly connected to the cleaning tank 1. Multiple sets of limiting balls 13 are movably sleeved inside the top of the first rotating rod 11. Multiple sets of limiting grooves 14 are formed at the bottom of the rotating shaft 10, and a guide groove 15 is formed between two sets of limiting grooves 14. The limiting grooves 14 are interconnected through the guide grooves 15. The cleaning component also includes multiple sets of first sliding grooves 16, all of which are formed on the outer side of the first rotating rod 11. The internal components are all slidably connected to a second rotating rod 17. Soft brushes 18 are fixedly connected to one side of the bottom of each of the multiple sets of second rotating rods 17. By starting the drive motor 9, the rotating shaft 10 and the first rotating rod 11 are driven to rotate. The rotation of the first rotating rod 11 drives the second rotating rods 17 and the soft brushes 18 to rotate, thus brushing the medical devices placed on the surface of the cleaning plate 20 and performing secondary cleaning of the attached organic matter. Initially, the vortex effect of the water flow may leave blind spots due to insufficient force. Secondary cleaning can specifically reinforce these areas, ensuring no residue and improving the cleaning effect. Furthermore, by cooperating with the circulation component, pre-wetting and softening can reduce brushing resistance and extend the service life of the devices.
[0025] The placement component includes two sets of second sliding grooves 19, which are respectively opened on both sides of the inside of the cleaning tank 1. Multiple sets of cleaning plates 20 are slidably connected inside the second sliding grooves 19. Multiple sets of water guide holes 21 are opened inside the cleaning plates 20. Multiple sets of water guide holes 21 are fixedly connected to the top of each cleaning plate 20. Multiple sets of limiting blocks 23 are fixedly connected to the top of the cleaning plates 20. Since the second rotating rod 17 and the cleaning plates 20 are both detachable structures, they can be completely separated, which can avoid the gaps or overlapping parts in the traditional fixed structure, ensuring that there are no blind spots in cleaning and disinfection. Moreover, the second rotating rod 17 and the cleaning plates 20 can be quickly replaced individually after damage or wear, reducing costs. In addition, the detachable structure can further reduce biofilm or organic residue, especially suitable for the pretreatment of stubborn contaminants such as blood stains and proteins, ensuring the hygiene and safety of medical devices.
[0026] Among them, multiple sets of water guide holes 21 are arranged in a ring, and multiple sets of limiting blocks 23 are arranged in a ring. The ring arrangement allows medical devices to be placed better and space to be used more rationally.
[0027] In this system, multiple sets of cleaning plates 20 are rotatably connected to the first rotating rod 11. The rotatable connection between the cleaning plates 20 and the first rotating rod 11 ensures that the cleaning components do not affect the cleaning plates 20 when they rotate, thereby cleaning the medical device.
[0028] The outlet of the output pipe 6 is tangent to the axis of the cleaning chamber 8. The output pipe 6 is located below the fixed connecting rod 12 and the two do not contact each other. The tangency between the outlet of the output pipe 6 and the axis of the cleaning chamber 8 gives the water flow inside the cleaning chamber 8 a driving force, causing the water flow to rotate along the inner wall of the cleaning chamber 8. This causes the water flow inside the cleaning chamber 8 to circulate, thereby generating a vortex to clean the medical device and soften the solidified tissue on its surface.
[0029] In this design, the length of multiple sets of second rotating rods 17 is shorter than the inner diameter of the cleaning chamber 8. The height between the bottom surface of the second rotating rod 17 and the top surface of the cleaning plate 20 is 3cm. The length of the soft brush 18 is 2cm. The height of the limiting block 23 and the limiting post 22 is 2cm. By setting the length of the soft brush 18, the soft brush 18 can extend into the interior of the limiting post 22 and the limiting block 23 and thus contact the limiting post 22 and the limiting block 23, thereby preventing impurities washed off from adhering to the surface of the limiting post 22 and the limiting block 23 and causing unnecessary corrosion.
[0030] The guide groove 15 is inclined inside, and the width of the guide groove 15 is equal to the diameter of the limiting ball 13. The inclined arrangement inside the guide groove 15 causes the rotating shaft 10 to contact the limiting ball 13 after being pressed down, thereby driving the first rotating rod 11 to move along the inclined groove of the guide groove 15, so that the limiting ball 13 moves into the interior of the limiting groove 14 to complete the engagement.
[0031] Working principle: During operation, pulling the handle 3 lifts the cover 2, causing the cover 2 to move upwards, disengaging from the first rotating rod 11. The used medical device is then placed on the surface of the cleaning plate 20. After placement, the cleaning plate 20 is placed into the cleaning chamber 8 along the second sliding groove 19. Since both the cleaning plate 20 and the second rotating rod 17 are sliding, the second rotating rod 17 can be set after the cleaning plate 20 is placed. During this process, since both the second rotating rod 17 and the cleaning plate 20 are detachable and can be completely separated, gaps or overlaps in traditional fixed structures are avoided, ensuring no blind spots in cleaning and disinfection. Furthermore, the second rotating rod 17 and the cleaning plate 20 can be quickly and individually replaced after damage or wear, reducing costs. The detachable structure further reduces biofilm or organic residue, making it particularly suitable for the pretreatment of stubborn contaminants such as blood stains and proteins, ensuring the hygiene and safety of medical devices. After placement, the water pump 4 is started to draw water into the cleaning chamber 8 through the inlet pipe 5 and the outlet pipe 6. The water flows out along the position tangential to the axis of the cleaning chamber 8, giving the water inside the cleaning chamber 8 a driving force, causing the water inside the cleaning chamber 8 to flow in a ring, thereby generating a vortex inside the cleaning chamber 8. The rotational kinetic energy of the vortex generates tangential shear force. Over time, the water will penetrate into the organic matter such as blood clots, proteins, fats, etc. that adhere to the surface of the medical device, softening the dried or cross-linked contaminants. Then, the rotating water flow will remove them from the surface of the medical device, reducing the initial bacterial count before disinfection, reducing the resistance of disinfectant to penetrate the biofilm, reducing the difficulty of sterilization, and improving the cleaning effect. After the water flow has been running for a period of time, the organic matter on the surface of the medical device is basically softened. At this time, the drive motor 9 is started to drive the rotating shaft 10 and the first rotating rod 11 to rotate. The rotation of the first rotating rod 11 drives the second rotating rod 17 and the soft brush 18 to rotate, brushing the medical device placed on the surface of the cleaning plate 20, and performing secondary cleaning of the attached organic matter on its surface. The initial use of the vortex effect of the water flow may leave blind spots due to insufficient force. The secondary cleaning can be targeted to strengthen the cleaning, ensuring no residue and improving the cleaning effect. In addition, by cooperating with the circulation component, pre-wetting and softening can reduce the brushing resistance and extend the service life of the device.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
