Abstract
Description
Technical Field
[0001] This invention specifically relates to a medical device cleaning device with a self-cleaning function. Background Technology
[0002] The cleanliness of medical devices is directly related to the safety of diagnosis and treatment and the health of patients. This is especially true for equipment such as surgical instruments, endoscopes, and dental instruments, which come into direct contact with human tissue. After use, it is essential to thoroughly remove bloodstains, tissue debris, medication residue, and other contaminants from their surfaces to avoid the risk of cross-infection. Currently, medical institutions primarily rely on two methods for cleaning medical devices: one is manual brushing with handheld brushes and sponges, and the other is using semi-automatic or fully automatic cleaning devices that use mechanically driven cleaning components to scrub the devices.
[0003] For example, Chinese invention patent with publication number CN111420947B provides an auxiliary brushing device for medical devices. The device has an adjustable clamping design, which allows it to clamp and position various tubular medical devices of different diameters. Furthermore, through a pressurized rotation design, the device can generate high pressure for rotational cleaning inside the tube wall, greatly improving the internal cleaning effect.
[0004] However, most existing medical device cleaning devices do not have a self-cleaning function, which means that dirt on the medical devices is easily left on the cleaning device during the cleaning process, affecting the subsequent cleaning effect of the cleaning device on the medical devices. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes a medical device scrubbing device with a self-cleaning function. This solves the technical problem mentioned in the background art, where most existing medical device scrubbing devices lack self-cleaning capabilities, resulting in stains on the medical devices easily remaining on the scrubbing device during the cleaning process, thus affecting the subsequent cleaning effect of the scrubbing device on the medical devices.

A cleaning scraper is provided on the flushing pipe. An opening and closing mechanism is provided on the handle and connected to the multiple sets of cleaning brushes to convert the rotation of the handle within a first angle into driving the multiple sets of cleaning brushes to slide open and close.

[0007] In a preferred embodiment, the opening and closing mechanism includes: The mounting ring is rotatably disposed within the housing along its axis, and has multiple sets of first sliding grooves formed in the circumferential direction. A slider is disposed on the cleaning brush and is slidably disposed within the first groove; A lifting ring, which is vertically and flexibly mounted on the mounting ring, is connected to multiple sets of sliders via a pushing assembly. The pushing assembly converts the sliding of the lifting ring into driving the sliders to slide. A control component, disposed on the grip and connected to the lifting ring, is configured to convert rotation of the grip within a first angle into driving the lifting ring to rise or fall.
[0008] In a preferred embodiment, the actuating component includes: A connecting post is disposed on the slider, and a second sliding groove is provided on the lifting ring, wherein the connecting post is slidably disposed within the second sliding groove; and A first drive column is disposed on the connecting column, and an inclined groove is provided on the side wall of the second slide groove, wherein the first drive column is slidably engaged in the inclined groove.
[0009] In a preferred embodiment, the control component includes: A drive ring is rotatably sleeved on the lifting ring and slidably disposed within the housing along its axis; A sliding seat is slidably disposed within the handle, and a first elastic element is disposed between the sliding seat and the inner wall of the handle; and The connecting rod is hinged at one end to the drive ring and at the other end to the sliding seat.
[0010] In a preferred embodiment, the drive mechanism includes: The drive cylinder is rotatably disposed within the housing along its axis, and the lifting ring is slidably disposed on the drive cylinder along its axis. A spiral track is arranged inside the drive cylinder; The second drive column is mounted on the flushing pipe and is slidably engaged within the spiral track; and The second elastic element has one end abutting against the flushing pipe and the other end abutting against the inner wall of the housing.
[0011] In a preferred embodiment, the end of the spiral track is connected to a straight track, and the second drive column slides within the straight track when the flushing pipe slides toward the outside of the housing.
[0012] In a preferred embodiment, an L-shaped plate is arranged around the drive cylinder, an annular groove is formed on the inner wall of the housing, the end of the L-shaped plate is slidably engaged in the annular groove, and a connecting sleeve is provided on the lifting ring, which is slidably fitted onto the L-shaped plate.
[0013] In a preferred embodiment, the linkage mechanism includes: A propulsion ring is slidably sleeved on the flushing pipe and abuts against the inner end of the housing; one end of the second elastic member abuts against the propulsion ring; and A transmission assembly, disposed on the grip and connected to the propulsion ring, converts rotation of the grip within a second angle into driving the propulsion ring to slide.
[0014] In a preferred embodiment, a limiting groove is formed on the outer wall of the flushing pipe, and a locking block is provided inside the propulsion ring. The locking block is slidably locked in the limiting groove and abuts against the end of the limiting groove.
[0015] In a preferred embodiment, the transmission assembly includes: The first gear is disposed at the end of the grip, and a notch is provided on its periphery; The second gear is rotatably disposed in the housing along its axis.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In use, the device connects to an external water source via a water supply pipe. During cleaning, the instrument's usable end is inserted into the housing, bringing it into contact with the end of the rinsing tube and pushing the tube to slide back and forth. As the tube slides, a drive mechanism rotates multiple sets of cleaning brushes, thus scrubbing the instrument. The reciprocating sliding motion of the instrument allows for multi-directional scrubbing, both horizontally and vertically, improving cleaning efficiency and effectively removing residue. During scrubbing, the handle can also be rotated within a specific angle. This rotation, via an opening and closing mechanism, drives multiple sets of cleaning brushes to slide open and close along an axis perpendicular to the housing, accommodating instruments of different sizes. After the instruments are cleaned, the handle can be rotated within a second angle. During rotation, the handle can be controlled by the opening and closing mechanism to bring multiple cleaning brushes together to the minimum distance, and the linkage mechanism controls the rinsing tube to slide outward from the housing. This allows the cleaning scraper to remove impurities attached to the cleaning brushes, and the rinsing solution to rinse the removed impurities. This effectively prevents impurities from remaining on the cleaning brushes during the instrument cleaning process and affecting the subsequent cleaning effect. It also reduces the frequency of cleaning the brushing device by the staff and reduces the labor intensity of the staff. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.
[0021] Example: like Figure 1 , 2 As shown in Figure 6, the present invention provides a medical device brushing device with self-cleaning function, including a housing 1, a handle 3 hinged to one side of the housing 1 and mounted by a torsion spring, an installation ring 8 rotatably disposed inside the housing 1, a plurality of cleaning brushes 10 circumferentially disposed on the installation ring 8 and sliding along the axis perpendicular to the housing 1, a rinsing pipe 24 slidably passing through the housing 1 along its axis, one end of the rinsing pipe 24 being connected to a water supply pipe 2, and the other end having a water outlet 27, and a cleaning scraper 26 disposed on the rinsing pipe 24.
[0022] When in use, the instrument end can be inserted into the housing 1 so that the instrument end abuts against the end of the rinsing tube 24. A groove can be made at the end of the rinsing tube 24 to limit the instrument end and prevent the instrument from detaching from the rinsing tube 24. The water supply pipe 2 is connected to the rinsing liquid, and the rinsing liquid can be sprayed onto the instrument through the water outlet 27 to rinse the surface of the instrument.
[0023] like Figure 7 , 8As shown, in this embodiment, the handle 3 is provided with an opening and closing mechanism connected to multiple sets of cleaning brushes 10. The opening and closing mechanism converts the rotation of the handle 3 within a first angle into driving the multiple sets of cleaning brushes 10 to slide open and close. The opening and closing mechanism includes a mounting ring 8 rotatably disposed in the housing 1 along its axis. Multiple sets of first sliding grooves 9 are circumferentially opened on the mounting ring 8. A slider 12 is provided on the cleaning brush 10. The slider 12 is slidably disposed in the first sliding groove 9. A lifting ring 15 is installed on the mounting ring 8. The lifting ring 15 is connected to the multiple sets of sliders 12 through a pushing component. The pushing component converts the sliding of the lifting ring 15 into driving the slider 12 to slide. The pushing component includes a connecting post 13 disposed on the slider 12. A second sliding groove 16 is opened on the lifting ring 15. The connecting post 13 is slidably disposed in the second sliding groove 16. A first driving post 14 is provided on the connecting post 13. An inclined groove 17 is opened on the side wall of the second sliding groove 16. The first driving post 14 is slidably locked in the inclined groove 17.
[0024] The lifting ring 15 can be lowered to drive the inclined groove 17 to move downward. The connecting column 13 can slide in the second slide groove 16. Thus, the slider 12 can be controlled to slide in the first slide groove 9 through the cooperation of the inclined groove 17 and the first drive column 14. During the sliding process, the multiple sets of sliders 12 can make the cleaning brush 10 move synchronously to open and close, so that the multiple sets of cleaning brushes 10 can fit the outside of medical devices of different sizes, thus improving the applicability of the device.
[0025] like Figure 2 , 4 As shown in Figure 7, in this embodiment, the opening and closing mechanism further includes a control component disposed on the handle 3 and connected to the lifting ring 15. The control component converts the rotation of the handle 3 within a first angle into driving the lifting ring 15 to rise and fall. The control component includes a drive ring 18 rotatably sleeved on the lifting ring 15. The drive ring 18 is slidably disposed in the housing 1 along its axis. A sliding seat 4 is slidably disposed inside the handle 3. A first elastic element 5 is disposed between the sliding seat 4 and the inner wall of the handle 3. One end of the connecting rod 7 is hinged to the drive ring 18, and the other end is hinged to the sliding seat 4.
[0026] During the initial process of gripping the handle 3, the position of the sliding seat 4 is elastically limited by the first elastic element 5, so that the handle 3 can push the drive ring 18 downward through the connecting rod 7 during rotation, thereby controlling the lifting ring 15 to move downward. Under the action of the torsion spring, the handle 3 can be controlled to reset. Thus, by gripping the handle 3, multiple sets of cleaning brushes 10 can be opened and closed. After the cleaning brushes 10 are closed to the lowest distance by continuously gripping the handle 3, the handle 3 continues to rotate, so that the sliding seat 4 slides on the handle 3 and compresses the first elastic element 5 to adapt to the movement of the handle 3.
[0027] like Figures 3 to 7As shown, in this embodiment, a drive mechanism connected to the cleaning brush 10 is provided on the rinsing pipe 24. The drive mechanism converts the sliding of the rinsing pipe 24 toward the housing 1 into driving the cleaning brush 10 to rotate. The drive mechanism includes a drive cylinder 21 rotatably disposed in the housing 1 along its axis, a lifting ring 15 slidably disposed on the drive cylinder 21 along its axis, a spiral track 22 arranged inside the drive cylinder 21, a second drive column 25 provided on the rinsing pipe 24, the second drive column 25 being slidably engaged in the spiral track 22, one end of the second elastic member 32 abutting against the rinsing pipe 24, and the other end abutting against the inner wall of the housing 1.
[0028] After the cleaning brush 10 is opened and closed to a suitable distance, the instrument can be slid back and forth in the housing 1 to drive the rinsing tube 24 to slide along its axis. The rinsing tube 24 can be reset by the cooperation of the second elastic element 32. During the reciprocating sliding process, the rinsing tube 24 can drive the drive cylinder 21 to rotate as a whole through the cooperation of the second drive column 25 and the spiral track 22. An L-shaped plate 19 is arranged around the drive cylinder 21. An annular groove 20 is opened on the inner wall of the housing 1. The end of the L-shaped plate 19 is slidably locked in the annular groove 20. A connecting sleeve 11 is provided on the lifting ring 15. The connecting sleeve 11 is slidably sleeved on the L-shaped plate 19. During the rotation of the drive cylinder 21, the lifting ring 15 can be driven to rotate through the cooperation of the L-shaped plate 19 and the connecting sleeve 11. The arrangement of the L-shaped plate 19 and the connecting sleeve 11 ensures that the lifting ring 15 can still be driven by the drive cylinder 21 after lifting. During rotation, the lifting ring 15 drives multiple sets of cleaning brushes 10 to reciprocate through the slider 12, thereby performing circumferential brushing on the medical device. In conjunction with the longitudinal sliding of the medical device, it can perform multi-directional brushing on the device, effectively cleaning stubborn impurities remaining in the gaps of the medical device.
[0029] like Figure 2 , 4 As shown in Figures 6 and 7, in this embodiment, the handle 3 is provided with a linkage mechanism connected to the flushing pipe 24. This linkage mechanism converts the rotation of the handle 3 within a second angle into driving the flushing pipe 24 to slide outwards from the housing 1. The linkage mechanism includes a push ring 30 slidably sleeved on the flushing pipe 24, which abuts against the inner end of the housing 1. One end of the second elastic member 32 abuts against the push ring 30. The handle 3 is provided with a transmission assembly connected to the push ring 30. This transmission assembly converts the rotation of the handle 3 within a second angle into driving the push ring 30 to slide. The transmission assembly includes a first gear 6 located at the end of the handle 3. The first gear 6 has a notch 28 on its circumference. A second gear 34 is rotatably arranged along its axis inside the housing 1. After the handle 3 is rotated by a first angle, the first gear 6 meshes with the second gear 34. A third gear 35 is coaxially connected to the second gear 34, and the diameter of the third gear 35 is larger than that of the second gear 34. A rack 33 is provided on the push ring 30, and the rack 33 meshes with the third gear 35.
[0030] When the handle 3 is gripped within the first angle, the arrangement of the notch 28 prevents the first gear 6 from meshing with the second gear 34, and causes the multiple sets of cleaning brushes 10 to close to their minimum distance. When the handle 3 is rotated within the second angle, the first gear 6 meshes with the second gear 34, thereby controlling the rotation of the second gear 34 to drive the rotation of the third gear 35. During rotation, the third gear 35 can control the sliding of the push ring 30 through meshing with the rack 33. During this sliding process, the push ring 30 can push the flushing pipe 24 towards the outside of the housing 1 via the second elastic element 32, and clean the cleaning brushes 10 through the cleaning scraper 26, flushing away any loosened impurities. Furthermore, it can be understood that the first angle is the angle when the first gear 6 is not meshing with the second gear 34 when the handle 3 rotates, and the second angle is the angle at which the first gear 6 can rotate when meshing with the second gear 34. The first and second angles together form the complete rotation angle of the handle 3.
[0031] like Figure 6 , 7 As shown, in this embodiment, the end of the spiral track 22 is connected to a straight track 23. When the flushing pipe 24 slides towards the outside of the housing 1, the second drive column 25 slides within the straight track 23. The arrangement of the straight track 23 provides space and limits the movement of the second drive column 25, while also allowing the second drive column 25 to directly engage with the spiral track 22 when the flushing pipe 24 slides towards the inside of the housing 1, effectively improving the stability of the internal structure of the device and its reliability during use. A limiting groove 29 is provided on the outer wall of the flushing tube 24, and a locking block 31 is provided in the push ring 30. The locking block 31 is slidably locked in the limiting groove 29 and abuts against the end of the limiting groove 29. When the flushing tube 24 slides toward the inside of the housing 1, the locking block 31 can slide relative to the limiting groove 29. When the handle 3 is released and controlled to return to its original position under the action of the torsion spring, the push ring 30 is driven to return to its original position. Thus, the locking block 31 pushes the end of the limiting groove 29 to reset the flushing tube 24 for subsequent use. This makes the entire operation of the device only require inserting the instrument into the housing 1, sliding it and gripping the handle, without any other cumbersome operation process. This effectively improves the convenience of using the device to clean medical instruments and to perform self-cleaning on the device.
[0032] Furthermore, it is understood that in some preferred embodiments, a high-temperature jet device can be added inside the device to facilitate the supply of high-temperature gas to the device after cleaning, thereby sterilizing the internal cleaning cavity, cleaning brush 10, and other structures that will come into contact with the instruments to be cleaned, further preventing bacterial growth and avoiding cross-infection. An ultraviolet disinfection lamp can also be added inside the device to disinfect the working area with ultraviolet light. This multi-stage disinfection process allows the equipment to self-clean, improving the subsequent cleaning effect. The installation and operation of the high-temperature jet device and the ultraviolet disinfection equipment are common techniques used by those skilled in the art and will not be elaborated upon here.
[0033] Specific usage and beneficial effects of the present invention: When in use, the device connects the water supply pipe 2 to an external water source. During cleaning, the end of the instrument is inserted into the housing 1, and the end of the instrument abuts against the end of the rinsing pipe 24, pushing the rinsing pipe 24 to slide back and forth. During the sliding process, the rinsing pipe 24 drives multiple sets of cleaning brushes 10 to rotate via a drive mechanism, thereby brushing the instrument. By coordinating with the reciprocating sliding of the instrument, it can perform multi-directional brushing in both horizontal and vertical directions, improving brushing efficiency and effectively cleaning residues on the instrument. During the brushing process, the handle 3 can also be rotated within a first angle by gripping it. During the rotation of the handle 3 at the first angle, the multiple sets of cleaning brushes 10 are driven to slide open and close along an axis perpendicular to the housing 1 via an opening and closing mechanism to accommodate cleaning instruments of different sizes. After the instruments are cleaned, the handle 3 can be gripped and rotated within the second angle. During the rotation, the handle 3 can be controlled by the opening and closing mechanism to close multiple sets of cleaning brushes 10 to the minimum distance, and the linkage mechanism can be used to control the rinsing tube 24 to slide outward from the housing 1, so that the cleaning scraper 26 can scrape off the impurities attached to the cleaning brushes 10, and the rinsing liquid can be used to rinse off the scraped impurities. This effectively prevents impurities from remaining on the cleaning brushes 10 during the instrument cleaning process and affecting the subsequent cleaning effect. At the same time, it reduces the frequency of cleaning the brushing device by the staff and reduces the labor intensity of the staff.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
