Description

Technical Field

[0001] This invention relates to the field of medical device cleaning technology, and more specifically to a pipe instrument cleaning device. Background Technology

[0002] With the development of my country's medical industry, the types and quantities of medical devices are increasing daily. To prevent patients from being infected by reusable medical devices, the cleaning of medical devices is particularly important. Most medical devices need to be cleaned after use. Currently, when cleaning respiratory tubing devices, spray-type cleaning and disinfection devices are generally used, or the entire internal tubing is inserted for spray cleaning. During cleaning, surgical instruments are placed in a tray, and then the tray is placed on the cleaning machine for cleaning, or a longer tube is inserted for spray cleaning.

[0003] However, cleaning pipe instruments requires cleaning not only the inner wall but also the outer wall. Currently, the cleaning of the outer and inner walls of pipe instruments is carried out separately. This means that no matter which side cleans the pipe instrument first, the part that was cleaned first will be contaminated, resulting in incomplete cleaning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a pipe instrument cleaning device that solves the problem that the cleaning of the outer and inner walls of pipe instruments is currently carried out separately. This results in contamination of the first part of the pipe instrument regardless of whether the outer or inner wall is cleaned first, leading to incomplete cleaning.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A pipe cleaning device, comprising:

[0007] The box body has an opening at the top;

[0008] A supporting arc plate, which is fixedly mounted on the inner bottom wall of the box by two first supporting plates, is used to place pipe instruments.

[0009] A cleaning mechanism is housed within a housing. The cleaning mechanism includes an outer cleaning component and an inner cleaning component. The outer cleaning component includes a rotating shaft, rotatably mounted between two first support plates via a second support plate. Multiple outer cleaning sleeves are fixed to the outer side of the rotating shaft. Each outer cleaning sleeve has an outer brush fixed to its outer surface. Multiple first clearance grooves are formed at the bottom of the supporting arc plate, each first clearance groove corresponding to one outer cleaning sleeve. The outer portion of the outer brush extends through the corresponding first clearance groove to the inner side of the supporting arc plate. The inner cleaning component is located at one end of the housing and is used to clean the inner wall of pipework instruments.

[0010] The drive assembly, located inside the housing, is used to drive the rotating shaft and the inner cleaning component to rotate, so that the outer brush and the inner cleaning component clean the outer wall and the inner wall of the pipe instrument, respectively. At the same time, the drive assembly can also drive the pipe instrument to move towards the inner cleaning component, so that the inner cleaning component cleans the inner wall of the pipe instrument.

[0011] The aforementioned pipe instrument cleaning device uses a drive assembly to move the pipe instrument towards the inner cleaning component inside the supporting arc plate. Simultaneously, the drive assembly drives the outer and inner cleaning components to operate, allowing the outer and inner cleaning components to clean the outer wall and inner wall of the pipe instrument, respectively. This ensures that the outer wall and inner wall of the pipe instrument are cleaned simultaneously, avoiding contamination caused by cleaning the outer and inner walls of the pipe instrument separately, and saving time.

[0012] Furthermore, the two ends of the housing are respectively provided with a left cavity and a right cavity. The internal cleaning components include a rotating rod and a cleaning ball. The rotating rod is rotatably mounted inside the housing via a third support plate, and one end of the rotating rod rotates through the side wall of the right cavity and extends into its interior. The other end is rotatably connected to a detachable cleaning ball. The diameter of the cleaning ball is larger than the inner diameter of the channel of the tubing instrument. The drive assembly can drive the end of the rotating rod located in the right cavity to rotate. When the drive assembly drives the tubing instrument to move inside the support arc plate, the cleaning ball can be inserted into the channel of the tubing instrument.

[0013] Furthermore, the inner cleaning component also includes a limiting ring and two limiting plates. The limiting plates are elastic. The limiting ring is slidably sleeved on the outer side of the end of the rotating rod near the cleaning ball. One end of the two limiting plates is symmetrically arranged on the outer side of the limiting ring. The two limiting plates are inclined. When the cleaning ball is inserted into the channel of the pipe instrument, the ends of the two limiting plates away from the limiting ring are pressed against the inner wall of the pipe instrument.

[0014] Furthermore, the drive assembly includes a drive motor, which is fixedly installed in the left cavity. One end of the rotating shaft rotates through the side wall of the left cavity and is then connected to the output shaft of the drive motor via a transmission assembly. The other end of the rotating shaft rotates through the side wall of the right cavity and is then connected to the end of the rotating rod via a transmission assembly.

[0015] Furthermore, the drive assembly also includes a screw and two sliders. The screw is rotatably mounted inside the housing and located on one side of the supporting arc plate via two fourth support plates. One end of the screw rotates through the side wall of the left cavity and is fixedly connected to the output shaft of the drive motor. The two sliders are threadedly fitted onto the outside of the screw at intervals. The outer surfaces of the two sliders near the supporting arc plate are both arc surfaces, and the arc surfaces of the two sliders are in close contact with the outer surface of the supporting arc plate. Limit pins are fixedly connected to the two sliders via drive rods. The distance between the two limit pins is greater than the length of the pipe instrument. A through second clearance groove is provided along the length direction on the side of the supporting arc plate near the screw. The second clearance groove passes through the end of the supporting arc plate near the inner cleaning part. The ends of the two limit pins away from the corresponding sliders slide through the second clearance groove and extend to the inner side of the supporting arc plate.

[0016] Furthermore, the transmission assembly includes a first sprocket, a second sprocket, and a chain. The first sprocket is fixedly sleeved on the outside of the output shaft of the drive motor, and the second sprocket is fixedly sleeved on the outside of the end of the rotating shaft located in the left cavity. The first sprocket and the second sprocket are rotatably connected by the chain, and the number of teeth on the second sprocket is greater than the number of teeth on the first sprocket.

[0017] Furthermore, the transmission assembly also includes a first gear and a second gear. The first gear is fixedly sleeved on the outer side of the end of the rotating rod located in the right cavity, and the second gear is fixedly sleeved on the outer side of the end of the rotating shaft located in the right cavity. The first gear and the second gear are meshed and connected.

[0018] Furthermore, the inside of the rotating rod and the rotating shaft is a hollow structure. The end of the rotating rod located in the right cavity is connected to the first inlet pipe, and the other end of the first inlet pipe is used to connect to the infusion pump. The end of the rotating shaft located in the left cavity is connected to the second inlet pipe, and the other end of the second inlet pipe is used to connect to the infusion pump.

[0019] The beneficial effects of this invention are as follows: This pipe instrument cleaning device uses a drive motor to drive the screw, shaft, and rod to rotate. The screw drives the limiting pin to move the pipe instrument, allowing the cleaning ball to slide into the pipe instrument's channel for cleaning. The shaft drives the outer brush to clean the outer wall of the pipe instrument, and the rod drives the limiting plate to rotate the pipe instrument. This rotation during movement allows the outer brush and cleaning ball to simultaneously clean both the outer wall and the inner wall of the channel, thoroughly cleaning both the inside and outside of the pipe instrument. This avoids the contamination caused by washing the outer and inner walls of the pipe instrument separately and saves time. Attached Figure Description

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

Thus, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] Please see Figures 1 to 2 ,in, Figure 1 and Figure 5 The pipe instrument in this invention is designated as 60. A pipe instrument cleaning device includes a housing 10, a supporting arc plate 20, a cleaning mechanism 30, and a drive assembly 40. The housing 10 has an opening at the top, and left and right cavities 11 and 12 are respectively opened at both ends of the housing 10. The supporting arc plate 20 is fixedly mounted on the inner bottom wall of the housing 10 by two first supporting plates 51 for placing pipe instruments. The cleaning mechanism 30 is disposed inside the housing 10 and includes an outer cleaning component 31 and an inner cleaning component 32, which are respectively disposed at both ends of the housing 10. The drive assembly 40 is disposed inside the housing 10 and is used to drive the outer cleaning component 31 and the inner cleaning component 32 to clean the outer wall and inner wall of the pipe instrument, respectively. An infusion pump is connected to the cleaning mechanism 30 to deliver cleaning fluid to the outer cleaning component 31 and the inner cleaning component 32.

[0036] In use, the pipe instrument is placed inside the support arc plate 20. The drive assembly 40 pushes the pipe instrument to move towards the inner cleaning component 32 inside the support arc plate 20. At the same time, the drive assembly 40 drives the outer cleaning component 31 and the inner cleaning component 32 to operate, so that the outer cleaning component 31 and the inner cleaning component 32 clean the outer wall and the inner wall of the channel of the pipe instrument respectively. This allows the outer wall and the inner wall of the channel of the pipe instrument to be cleaned at the same time, avoiding the contamination caused by cleaning the outer wall and the inner wall of the pipe instrument separately, and saving time.

[0037] Please refer to the following: Figure 3 and Figure 4Specifically, the outer wall cleaning component includes a rotating shaft 311, which is rotatably mounted between two first support plates 51 via a second support plate 52. Multiple outer cleaning sleeves 312 are fixed to the outer side of the rotating shaft 311. Each outer cleaning sleeve 312 has an outer brush 313 fixed to its outer surface. Multiple first clearance grooves 21 are provided at the bottom of the supporting arc plate 20, each corresponding to an outer cleaning sleeve 312. The outer portion of the outer brush 313 extends through the corresponding first clearance groove 21 to the inner side of the supporting arc plate 20. The driving assembly 40 can drive the rotating shaft 311 to rotate, allowing the outer brush 313 to clean the outer wall of the pipe instrument. The inner cleaning component 32 is located at one end of the housing 10 and is used to clean the inner wall of the pipe instrument.

[0038] After the pipe instrument is placed inside the support arc plate 20, the drive assembly 40 drives the rotating shaft 311 to rotate, which in turn drives the outer cleaning sleeve 312 and the outer brush 313 to rotate together. This allows multiple outer brushes 313 to brush different positions on the outer wall of the pipe instrument. Moreover, since the pipe instrument can move inside the support arc plate 20, every position on the outer wall of the pipe instrument will be cleaned, thus cleaning the outer wall of the pipe instrument thoroughly through the outer wall cleaning component.

[0039] In this embodiment, the inner cleaning component 32 includes a rotating rod 321 and a cleaning ball 322. The rotating rod 321 is rotatably mounted inside the housing 10 via a third support plate 53. One end of the rotating rod 321 extends through the side wall of the right cavity 12 and into its interior, while the other end is rotatably connected to a detachable cleaning ball 322. The diameter of the cleaning ball 322 is larger than the inner diameter of the pipe instrument's channel. The driving assembly 40 can drive the end of the rotating rod 321 located inside the right cavity 12 to rotate. When the driving assembly 40 drives the pipe instrument to move inside the support arc plate 20, the cleaning ball 322 can be inserted into the channel of the pipe instrument. The cleaning ball 322 is elastic, and its front end is a protruding tip, which facilitates the insertion of the cleaning ball 322 into the channel of the pipe instrument. When the pipe instrument is placed inside the support arc plate 20, the cleaning ball 322 contacts the end of the pipe instrument. At this time, the protruding tip of the cleaning ball 322 is located inside the end of the pipe instrument, thus preventing the movement trajectory of the pipe instrument from deviating during the cleaning process.

[0040] After the pipe instrument is placed inside the support arc plate 20, the drive assembly 40 drives the pipe instrument to move in the direction of the inward cleaning component 32, so that the cleaning ball 322 moves in the channel of the pipe instrument. As the cleaning ball 322 is squeezed and contracted, the outer wall of the cleaning ball 322 is tightly attached to the inner wall of the channel of the pipe instrument, so that the cleaning ball 322 cleans the inner wall of the channel of the pipe instrument during the movement.

[0041] Preferably, the inner cleaning component 32 further includes a limiting ring 323 and two limiting pieces 324. The limiting pieces 324 are elastic. The limiting ring 323 is slidably sleeved on the outer side of the end of the rotating rod 321 near the cleaning ball 322. One end of the two limiting pieces 324 is symmetrically arranged on the outer side of the limiting ring 323. The two limiting pieces 324 are inclined. When the cleaning ball 322 is inserted into the channel of the pipe instrument, the ends of the two limiting pieces 324 away from the limiting ring 323 are pressed against the inner wall of the pipe instrument.

[0042] As the cleaning ball 322 slides into the pipe instrument channel, the outer walls of the two limiting plates 324 are squeezed towards the outer wall of the limiting ring 323 due to the pressure of the inner wall of the pipe instrument channel, causing the two limiting plates 324 to slide into the pipe instrument channel. At this time, the ends of the two limiting plates 324 away from the limiting ring 323 are tightly attached to the inner wall of the pipe instrument. When the rotating rod 321 drives the limiting ring 323 to rotate, the two limiting plates 324 rotate together with the limiting ring 323. Due to the friction between the ends of the limiting plates 324 and the inner wall of the pipe instrument, the pipe instrument is driven to rotate by the limiting plates 324, thereby making the cleaning ball 322 clean the inner wall of the pipe instrument channel more thoroughly and cleanly.

[0043] like Figure 1 As shown, in this embodiment, the drive assembly 40 includes a drive motor 41, which is a forward and reverse reversible motor. The drive motor 41 is fixedly installed in the left cavity 11. One end of the rotating shaft 311 rotates through the side wall of the left cavity 11 and is connected to the output shaft of the drive motor 41 via a transmission assembly. The other end of the rotating shaft 311 rotates through the side wall of the right cavity 12 and is connected to the end of the rotating rod 321 via a transmission assembly. The rotating rod 321 and the rotating shaft 311 have hollow interiors. The end of the rotating shaft 311 located in the right cavity 12 is a closed end. The end of the rotating rod 321 located in the right cavity 12 is connected to a second inlet pipe 325, and the other end of the second inlet pipe 325 is used to connect to an infusion pump. The end of the rotating shaft 311 located in the left cavity 11 is connected to a first inlet pipe 314, and the other end of the first inlet pipe 314 is used to connect to an infusion pump. The cleaning ball 322 has multiple first outlet holes 316, and the rotating shaft 311 has multiple second outlet holes 315 at the position corresponding to the outer cleaning sleeve 312. The second outlet holes 315 penetrate the outer cleaning sleeve 312.

[0044] When the drive motor 41 starts, it drives the rotating shaft 311 and the rotating rod 321 to rotate. As the pipeline instrument moves inside the support arc plate 20, the rotating shaft 311 drives the outer brush 313 to clean the pipeline instrument, and the rotating rod 321 drives the cleaning ball 322 to clean the inner wall of the pipeline instrument channel. Moreover, the infusion pump delivers the cleaning solution to the outer and inner walls of the pipeline instrument through the first inlet pipe 314 and the second inlet pipe 325 respectively, thereby cleaning the dirt on the pipeline instrument.

[0045] Please refer to the following: Figure 3 , Figure 4 and Figure 5 Specifically, the drive assembly 40 also includes a screw 42 and two sliders 43. The screw 42 is rotatably mounted inside the housing 10 and located on one side of the supporting arc plate 20 via two fourth support plates 54. One end of the screw 42 rotates through the side wall of the left cavity 11 and is fixedly connected to the output shaft of the drive motor 41. The two sliders 43 are threadedly sleeved on the outside of the screw 42 at intervals. The outer surfaces of the two sliders 43 near the supporting arc plate 20 are both arc surfaces, and the arc surfaces of the two sliders 43 are in contact with and slidably connected to the outer surfaces of the supporting arc plate 20. Limiting pins 44 are fixedly connected to the two sliders 43 via drive rods 45. The distance between the two limiting pins 44 is greater than the length of the pipe instrument. A through second clearance groove 22 is provided along the length direction on the side of the supporting arc plate 20 near the screw 42. The second clearance groove 22 passes through the end of the supporting arc plate 20 near the inner cleaning component 32. The ends of the two limiting pins 44 away from the corresponding sliders 43 slide through the second clearance groove 22 and extend to the inner side of the supporting arc plate 20.

[0046] When the pipe instrument is placed inside the support arc plate 20, it is positioned between the ends of the two limiting pins 44. After the drive motor 41 starts rotating forward, it drives the screw 42 to rotate, causing the two sliders 43 and the two limiting pins 44 to move synchronously towards the right cavity 12. When the end of the limiting pin 44 closest to the drive motor 41 touches the pipe instrument, it pushes the pipe instrument to move synchronously, thus moving the pipe instrument inside the support arc plate 20. When the drive motor 41 starts rotating in reverse, it drives the screw 42 to rotate, causing the two sliders 43 and the two limiting pins 44 to move synchronously towards the left cavity 11. When the end of the limiting pin 44 furthest from the drive motor 41 touches the pipe instrument, it pushes the pipe instrument to move synchronously back. Through the reciprocating movement of the pipe instrument inside the support arc plate 20, the cleaning ball 322 slides into the channel of the pipe instrument for cleaning, while the outer brush 313 cleans every part of the outer wall of the pipe instrument, cleaning both the inside and outside of the pipe instrument simultaneously.

[0047] Preferably, the transmission assembly includes a first sprocket 461, a second sprocket 462, and a chain 463. The first sprocket 461 is fixedly sleeved on the outside of the output shaft of the drive motor 41, and the second sprocket 462 is fixedly sleeved on the outside of the end of the rotating shaft 311 located in the left cavity 11. The first sprocket 461 and the second sprocket 462 are rotatably connected by the chain 463. The second sprocket 462 has more teeth than the first sprocket 461, causing the screw 42 to rotate at a speed less than that of the rotating shaft 311. This ensures that the external brush 313 cleans every part of the outer wall of the pipe instrument during its movement. The drive motor 41 starts and drives the first sprocket 461 to rotate, which in turn drives the second sprocket 462 and the rotating shaft 311 to rotate, thus causing the external brush 313 to clean the outer wall of the pipe instrument. Simultaneously, the drive motor 41 also drives the screw 42 to rotate.

[0048] The transmission assembly also includes a first gear 464 and a second gear 465. The first gear 464 is fixedly sleeved on the outer side of the end of the rotating rod 321 located inside the right cavity 12, and the second gear 465 is fixedly sleeved on the outer side of the end of the rotating shaft 311 located inside the right cavity 12. The first gear 464 and the second gear 465 are meshed together. The number of teeth of the second gear 465 is 2-4 times that of the first gear 464, so that the rotational speed of the rotating rod 321 is 2-4 times that of the rotating shaft 311. This allows the rotating rod 321 to drive the pipe instrument to rotate faster, while the moving speed of the pipe instrument is less than its rotational speed, which facilitates the cleaning of the outer wall of the pipe instrument by the outer brush 313.

[0049] The working principle of this invention is as follows: In use, when the pipe instrument is placed inside the support arc plate 20, it is positioned between the ends of the two limiting pins 44, and the protruding tip of the cleaning ball 322 is located inside the end of the pipe instrument. Then, the drive motor 41 is started to rotate forward, causing the end of the limiting pin 44 closest to the drive motor 41 to touch the pipe instrument. This limiting pin 44 pushes the pipe instrument to move synchronously, causing the pipe instrument to move towards the right cavity 12 inside the support arc plate 20. Simultaneously, the forward rotation of the drive motor 41 drives the rotating shaft 311 and the rotating rod 321 to rotate, causing the rotating shaft 311 to drive the outer brush 313 to move against the pipe instrument. During cleaning, as the tubing instrument moves inside the supporting arc plate 20, the cleaning ball 322 slides into the channel of the tubing instrument. Due to the pressure from the inner wall of the tubing instrument channel, the outer walls of the two limiting plates 324 converge towards the outer wall of the limiting ring 323, causing the ends of the two limiting plates 324 to adhere tightly to the inner wall of the tubing instrument. This causes the tubing instrument to rotate as the two limiting plates 324 rotate, thus cleaning the inner wall of the tubing instrument channel as the cleaning ball 322 moves. Furthermore, the infusion pump delivers cleaning fluid to the outer and inner walls of the tubing instrument through the second inlet pipe 325 and the first inlet pipe 314, respectively.

[0050] Then, the drive motor 41 is started to reverse, causing the thread to reverse, so that the pipe instrument moves to the left cavity 11 inside the support arc plate 20. The outer brush 313 and the cleaning ball 322 clean the outer wall and the inner wall of the channel of the pipe instrument again. The reciprocating movement of the pipe instrument is driven by the drive motor 41, thereby thoroughly cleaning the outer wall and the inner wall of the channel of the pipe instrument at the same time.

[0051] The beneficial effects of this invention are as follows: This pipe instrument cleaning device drives the screw 42, rotating shaft 311, and rotating rod 321 to rotate via a drive motor 41. This causes the screw 42 to drive the limiting pin 44 to move the pipe instrument, thereby allowing the cleaning ball 322 to slide into the channel of the pipe instrument for cleaning. The rotating shaft 311 drives the outer brush 313 to clean the outer wall of the pipe instrument, and the rotating rod 321 drives the limiting plate 324 to rotate the pipe instrument. As the pipe instrument rotates during its movement, the outer brush 313 and the cleaning ball 322 simultaneously clean the outer wall and the inner wall of the channel of the pipe instrument, thoroughly cleaning both the inside and outside of the pipe instrument. This avoids the contamination caused by washing the outer and inner walls of the pipe instrument separately and saves time.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
