Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a pre-filled catheter flushing device sterilization equipment and process. Background Technology

[0002] In modern medicine, pre-filled catheter flushing devices are widely used as important medical devices in various medical procedures. However, ensuring that these flushing devices achieve a strictly sterile state after use is crucial, as it directly relates to patient health and the safety of medical procedures.

[0003] Traditional sterilization methods and equipment for pre-filled catheter flushing devices have many limitations. In the past, common sterilization methods might have included simple chemical immersion disinfection, where the flushing device is completely submerged in a disinfectant solution. However, this method often suffers from uneven disinfection, especially with the complex structure and internal cavities of the flushing device, making it difficult to ensure that the disinfectant solution fully penetrates and contacts all parts. Furthermore, after immersion disinfection, the flushing device requires a tedious drying process, usually air-drying or simple wind drying. This is not only time-consuming but also difficult to guarantee drying effectiveness, easily leaving residual moisture and creating conditions for bacterial growth.

[0004] Furthermore, some sterilization equipment lacks an effective mechanism for fixing and batch processing multiple irrigators. It can only operate on one or a small number of irrigators at a time, resulting in low efficiency and failing to meet the medical industry's demand for rapid sterilization of large numbers of irrigators.

[0005] Furthermore, existing sterilization equipment has shortcomings in the distribution and application of disinfectant gases or liquids. Disinfectant gases or liquids may not evenly cover the outer surface of the rinser, resulting in incomplete disinfection in some areas. Inside the rinser, due to its structural characteristics, it is often difficult for the disinfectant medium to fully penetrate and function, thus affecting the overall sterilization effect.

[0006] To address this, we propose a pre-filled catheter flushing sterilization device and process. This device can simultaneously fix multiple flushers for sterilization, greatly improving production efficiency. At the same time, the rotation of the rotating ring ensures that all external parts of the flusher can be uniformly sterilized by atomized gas. Furthermore, the movement of the flusher's push-pull head allows the interior to fully absorb atomized disinfectant gas, achieving comprehensive sterilization both inside and out. Summary of the Invention

[0007] The purpose of this invention is to provide a pre-filled catheter flushing sterilization device and process. This device can not only fix multiple flushers for sterilization at the same time, greatly improving production efficiency, but also ensure that all external parts of the flusher can be uniformly sterilized by atomized gas through the rotation of the rotating ring; while the movement of the flusher push-pull head can also fully absorb the atomized disinfecting gas inside, achieving comprehensive sterilization inside and out.

[0012] The upper chamber is equipped with a drying component, and the lower chamber is equipped with an atomizing gas guiding component.

[0013] Furthermore, the first rotating assembly includes a first stepper motor disposed on the support plate, the output end of which is connected to the first gear.

[0014] Furthermore, the fixing component includes a hollow shell disposed on the connecting plate, a spring disposed inside the hollow shell, a piston plate disposed on one side of the spring, a moving rod disposed on the piston plate, the end of the moving rod away from the piston plate passing through the hollow shell and mounted with an arc-shaped plate, and an arc-shaped groove for fixing the flushing device along its edge is provided on the arc-shaped plate.

[0015] Furthermore, the atomizing component includes a water tank for storing disinfectant, which is disposed on the upper and lower housings. A water guide pipe is provided at the bottom of the water tank, and a water pump is provided on the water guide pipe. The end of the water guide pipe away from the water tank passes through the lower housing and is connected to the atomizing nozzle.

[0016] Furthermore, the telescopic assembly includes an electrically operated telescopic rod disposed on the lower housing, the telescopic end of which is connected to the first connecting plate.

[0017] Furthermore, the second rotating assembly includes a second stepper motor disposed at the center of the first connecting disk, and the output end of the second stepper motor is connected to the rotating disk.

[0018] Furthermore, the movable component includes a threaded rod disposed inside the slide groove, one end of the threaded rod extending through the second connecting disc and connected to the second gear, a threaded sleeve being fitted onto the threaded rod, and one side of the threaded sleeve being connected to the fixed plate.

[0019] Furthermore, the atomizing gas guiding assembly includes a first protective housing disposed inside the lower housing, a first motor disposed inside the first protective housing, and a first fan blade installed at the output end of the first motor.

[0020] Furthermore, the air-drying assembly includes a second protective housing disposed inside the upper housing, a second motor disposed inside the second protective housing, and a second fan blade installed at the output end of the second motor.

[0021] A sterilization process for a pre-filled catheter flushing device includes a pre-filled catheter flushing device sterilization equipment, comprising the following steps:

[0022] S1: Place the pre-filled tubing flusher to be sterilized between every two connecting plates to ensure the flusher housing is stably positioned;

[0023] Secure the edges on the flusher housing with fastening components to ensure that multiple flushers are secured simultaneously, thereby improving work efficiency.

[0024] S2: Start the first rotating component, drive the first gear to rotate, the first gear meshes with the first meshing tooth on the outer side of the rotating ring, drive the rotating ring to rotate in the arc-shaped sliding groove, the rotating ring drives the fixed ring and the connected flushing device to move until the flushing device corresponds to the position of the atomizing nozzle inside the lower box.

[0025] The atomizing component starts working, converting the disinfectant liquid into atomized gas, which is then sprayed onto the outside of the rinser through the atomizing nozzle. The atomized gas guiding component guides the atomized gas to evenly cover the outside of the rinser for external disinfection and sterilization.

[0026] S3: The telescopic component is activated, driving the first connecting plate and its second rotating component and connecting rod to move towards the flusher. When the flusher push-pull head enters the limiting groove on the two connecting blocks on the second connecting plate, the second rotating component starts to work. The rotating plate rotates in the through hole, and its second meshing teeth mesh with the second gear on the moving component, driving the second gear to move the fixed plate up and down. The movement of the fixed plate drives the flusher push-pull head to move inside the flusher housing, so that the interior can fully absorb the atomized disinfection and sterilization gas to achieve internal sterilization.

[0027] S4: After external and internal sterilization is completed, all devices are returned to their original positions;

[0028] The first rotating component starts again, driving the rotating ring to rotate and move the sterilized rinsing device into the upper chamber. The air drying component inside the upper chamber starts to air dry the rinsing device to ensure that there is no residual liquid.

[0029] S5: Repeat the above steps to sterilize the next batch of rinsers. Throughout the process, the equipment operates automatically, which greatly improves production efficiency and ensures the comprehensive sterilization effect of the rinsers.

[0030] The technical effects achieved by this invention are as follows:

[0031] When using the device, the flushing device is first placed between two connecting plates. Then, the edge of the flushing device housing is secured using a fixing assembly. This allows for the fixing of multiple flushing devices, improving work efficiency. Next, the first rotating assembly drives the first gear to rotate, which in turn drives the first meshing teeth to rotate the rotating ring within the arc-shaped groove. This aligns the rotating ring with the fixing ring, positioning it against the second connecting plate. The atomizing assembly then directs the disinfectant liquid into the atomizing nozzle, allowing the atomized gas to enter the lower housing. The atomized gas guiding assembly then sprays the atomized gas onto the flushing device, disinfecting its exterior. Simultaneously, the telescopic assembly moves the first connecting plate, which is connected via a connecting... The connecting rod drives the second connecting plate and the second rotating assembly to move. When they move to allow the flushing head to enter the limiting grooves on the two connecting blocks, the second rotating assembly drives the rotating plate to rotate. The rotating plate drives the second meshing gear to rotate the second gear, which in turn drives the moving assembly to move the fixed plate up and down. This causes the flushing head to move inside the flushing housing and draw in atomized disinfecting gas, thus disinfecting the inside of the flushing device. After disinfection, all devices return to their original positions. Then, the first rotating assembly drives the first gear to rotate the rotating ring, moving the disinfected flushing device into the upper chamber. The drying assembly then dries the flushing device, and the process is repeated. This device can simultaneously fix multiple flushing devices for sterilization, greatly improving production efficiency. The rotation of the rotating ring ensures that all external parts of the flushing device receive uniform sterilization treatment from the atomized gas. The movement of the flushing head also allows the internal parts to fully absorb the atomized disinfecting gas, achieving comprehensive internal and external sterilization.

[0044] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0045] like Figure 1-10 As shown, the technical solution adopted by the present invention is as follows: A pre-filled catheter flushing sterilization device includes an upper box 1 and a lower box 2 disposed at the bottom of the upper box 1. A support plate is disposed on the outer side of the upper box 1, and a first rotating component is disposed on the support plate. A first gear 3 is disposed on the first rotating component. Both the upper box 1 and the lower box 2 are provided with arc-shaped sliding grooves 4. A rotating ring 5 is disposed inside the arc-shaped sliding groove 4. A first meshing tooth 6 that meshes with the first gear 3 is disposed on the outer side of the rotating ring 5. A plurality of fixing rings 7 are fixedly disposed on the inner wall of the rotating ring 5. A plurality of connecting plates 8 are arranged in an array inside the fixing rings 7. A fixing component for fixing the flushing device housing is disposed on the side of each pair of connecting plates 8 that are close to each other.

[0046] Atomizing components are provided on the outside of the upper housing 1 and the lower housing 2. Atomizing nozzles 9 are provided on the atomizing components and are located inside the lower housing 2. The positions of the atomizing nozzles 9 and the rinsing device fixing components are corresponding.

[0047] The lower housing 2 is provided with a telescopic assembly. The telescopic end of the telescopic assembly is equipped with a first connecting plate 10. The first connecting plate 10 is provided with a second rotating assembly and a connecting rod 11. The end of the connecting rod 11 away from the first connecting plate 10 is equipped with a second connecting plate 12. The second connecting plate 12 is provided with multiple sliding grooves 13 and a through hole. Each sliding groove 13 is provided with a moving assembly. The moving assembly is provided with a second gear 14 and a fixing plate 15. The fixing plate 15 is provided with two connecting blocks 16. The two connecting blocks 16 are provided with limiting grooves for fixing the push-pull head of the flusher. The second rotating assembly is provided with a rotating disk 17 located inside the through hole. The rotating disk 17 is provided with a second meshing tooth 18 that meshes with the second gear 14.

[0048] The upper chamber 1 is equipped with a drying component, and the lower chamber 2 is equipped with an atomizing gas guiding component.

[0049] Its working principle is as follows: When in use, the flushing device is first placed between every two connecting plates 8, and then the edge on the flushing device housing is fixed by the fixing component. This allows multiple flushing devices to be fixed, improving work efficiency. Then, the first rotating component drives the first gear 3 to rotate, and the first gear 3 drives the first meshing teeth 6 to make the rotating ring 5 rotate inside the arc-shaped sliding groove 4, thereby causing the rotating ring 5 to drive the fixing ring 7 to align with the position of the second connecting plate 12. Then, the disinfectant liquid enters the atomizing nozzle 9 through the atomizing component, thereby causing the atomized gas to enter the lower housing 2. Then, the atomized gas guide component sprays the atomized gas onto the flushing device to disinfect and sterilize the outside of the flushing device. At the same time, the telescopic component drives the first connecting plate 10 to move, and the first connecting plate 10 passes through... The connecting rod 11 drives the second connecting plate 12 and the second rotating assembly to move. When the second rotating assembly moves to allow the flushing push-pull head to enter the limiting groove on the two connecting blocks 16, the second rotating assembly drives the rotating disk 17 to rotate. The rotating disk 17 drives the second meshing gear 18 to rotate the second gear 14. The second gear 14 drives the moving assembly to move the fixing plate 15 up and down, thereby moving the flushing push-pull head inside the flushing housing and drawing in the atomized disinfecting gas to disinfect the inside of the flushing. After disinfection, each device returns to its original position. Then, the first rotating assembly drives the first gear 3 to rotate the rotating ring 5, thereby moving the disinfected flushing into the upper housing 1. The flushing is then dried by the air-drying assembly, and this process is repeated. This device can not only fix multiple flushing devices for sterilization at the same time, greatly improving production efficiency, but also ensures that all external parts of the flushing are evenly treated with atomized gas through the rotation of the rotating ring 5. The movement of the flushing push-pull head allows the inside to fully draw in the atomized disinfecting gas, achieving comprehensive sterilization inside and out.

[0050] In the prior art, the flushing device body includes a housing and a piston disposed inside the housing. The piston is provided with a push-pull rod, and the top of the push-pull rod is provided with a push-pull head that is larger than the diameter. At the same time, the housing also has an edge. The edge and the push-pull head are mostly circular in shape. The fixing component of the present invention is to fix the edge of the housing, and the shape of the limiting groove is the same as the shape of the push-pull head, so it can be fixed and limited.

[0051] At the same time, such as Figure 1 As shown, the first rotating assembly includes a first stepper motor 19 mounted on a support plate. The output end of the first stepper motor 19 is connected to the first gear 3, and the first gear 3 is driven to rotate by the first stepper motor 19.

[0052] The arc-shaped slide 4 is matched with the rotating ring 5. Matching here means that the rotating ring 5 can rotate smoothly inside the arc-shaped slide 4. At the same time, the width of the arc-shaped slide 4 should be sufficient to allow the rotating ring 5 to drive the fixed ring 7 to rotate in the upper box 1 and the lower box 2.

[0053] like Figure 8 As shown, the fixing assembly includes a hollow housing 20 disposed on the connecting plate 8. A spring 21 is disposed inside the hollow housing 20. A piston plate 22 is disposed on one side of the spring 21. A moving rod 23 is disposed on the piston plate 22. The end of the moving rod 23 away from the piston plate 22 passes through the hollow housing 20 and is fitted with an arc-shaped plate 34. An arc-shaped groove for fixing the edge of the flushing device is provided on the arc-shaped plate 34.

[0054] When people are fixing it, the moving rod 23 is moved by the arc plate 34. The moving rod 23 drives the piston plate 22 to squeeze the spring 21 inside the hollow shell 20, and then the flusher enters the arc groove along the edge. Then the flusher is fixed by the elastic force of the spring 21.

[0055] The curved groove design allows for better contact with the edge of the flushing device, thus improving the fixation effect.

[0056] Furthermore, an atomizing gas flow cavity is formed between every two connecting plates 8. During the disinfection process, the fine gas generated by the atomizing component is first guided into these flow cavities. Due to the reasonable design of the cavities, the gas flow within them becomes smooth and orderly, avoiding the generation of adverse factors such as turbulence and eddies. This smooth flow not only ensures that the gas can evenly cover the surface of the rinsing device, but also makes the disinfection effect more thorough and uniform.

[0057] like Figure 3As shown, the atomizing assembly includes a water tank 24 for storing disinfectant, which is disposed on the upper chamber 1 and the lower chamber 2. A water guide pipe 25 is provided at the bottom of the water tank 24, and a water pump is provided on the water guide pipe 25. The end of the water guide pipe 25 away from the water tank 24 passes through the lower chamber 2 and is connected to the atomizing nozzle 9. The water pump provides power, and then the disinfectant inside the water tank 24 enters the atomizing nozzle 9 through the water guide pipe 25. The disinfectant liquid is atomized by the atomizing nozzle 9, so that the atomized gas enters the lower chamber 2.

[0058] Atomizing nozzle 9 is a device that can convert liquid into fine droplets and spray them out. Its working principle is based on the liquid being dispersed into tiny droplets through a specific structural design, and then sprayed out by airflow. Atomizing nozzle 9 typically consists of multiple tiny nozzles or thin plates, the size and shape of which play a crucial role in the droplet size and dispersion. Through the action of these nozzles or thin plates, the liquid forms a high-speed, fine jet stream as it passes through the nozzle. A suitable model for atomizing nozzle 9 is the ST-6 pressure atomizing nozzle 9.

[0059] The telescopic assembly includes an electric telescopic rod 26 mounted on the lower housing 2. The telescopic end of the electric telescopic rod 26 is connected to the first connecting plate 10, and the electric telescopic rod 26 drives the first connecting plate 10 to move.

[0060] like Figure 9 As shown, the second rotating assembly includes a second stepper motor 27 disposed at the center of the first connecting disk 10. The output end of the second stepper motor 27 is connected to the rotating disk 17, and the rotating disk 17 is driven to rotate by the second stepper motor 27.

[0061] like Figure 9 As shown, the moving component includes a threaded rod 28 disposed inside the slide groove 13. One end of the threaded rod 28 extends through the second connecting plate 12 and is connected to the second gear 14. A threaded sleeve 29 is fitted on the threaded rod 28. One side of the threaded sleeve 29 is connected to the fixed plate 15. When the second gear 14 rotates, it drives the threaded rod 28 to rotate. The threaded rod 28 drives the threaded sleeve 29 to move the fixed plate 15, thereby disinfecting and sterilizing the inside of the flushing device.

[0062] like Figure 3 As shown, the atomizing gas guiding assembly includes a first protective housing 30 disposed inside the lower housing 2. A first motor is disposed inside the first protective housing 30. A first fan blade 31 is installed at the output end of the first motor. The first motor drives the first fan blade 31 to rotate, thereby allowing the atomized gas to be guided to the flushing device through the rotation of the first fan blade 31.

[0063] It should be noted that the atomizing nozzle 9 is located inside the first protective housing 30, which allows the atomized gas to be directly discharged during atomization.

[0064] like Figure 3 As shown, the air-drying assembly includes a second protective housing 32 disposed inside the upper housing 1. A second motor is disposed inside the second protective housing 32, and a second fan blade 33 is installed at the output end of the second motor. The second fan blade 33 is driven by the second motor to rotate, thereby circulating air and drying the disinfection and sterilization rinser.

[0065] Both the upper chamber 1 and the lower chamber 2 are equipped with ventilation holes (not shown in the figure) to allow air circulation.

[0066] It should be noted that condensation will occur after the atomized disinfectant is used. This disinfectant will be stored inside the lower tank 2. Existing technologies can be used to treat it, such as using filter plates and recycling it for reuse. Alternatively, it can be recycled back into the water tank 24 using a circulation pump. These are existing technologies and will not be elaborated on here.

[0067] A sterilization process for a pre-filled catheter flushing device: including a pre-filled catheter flushing device sterilization equipment, the steps of which are as follows:

[0068] 1. Preparation stage:

[0069] Place the pre-filled catheter flusher to be sterilized between every two connecting plates 8, ensuring the flusher housing is stably positioned.

[0070] Secure the edges on the flusher housing using fastening components to ensure that multiple flushers are secured simultaneously, thus improving work efficiency.

[0071] 2. External sterilization treatment:

[0072] Start the first rotating component, which drives the first gear 3 to rotate. The first gear 3 meshes with the first meshing tooth 6 on the outer side of the rotating ring 5, driving the rotating ring 5 to rotate in the arc-shaped slide groove 4. The rotating ring 5 drives the fixed ring 7 and the connected flushing device to move until the flushing device corresponds to the position of the atomizing nozzle 9 inside the lower box 2.

[0073] The atomizing component starts working, converting the disinfectant liquid into atomized gas, which is then sprayed onto the outside of the rinser through the atomizing nozzle 9. The atomized gas guiding component guides the atomized gas to evenly cover the outside of the rinser for external disinfection and sterilization.

[0074] 3. Internal sterilization process:

[0075] When the telescopic assembly is activated, it drives the first connecting plate 10 and its second rotating assembly and connecting rod 11 to move towards the flusher. When the flusher push-pull head enters the limiting groove on the two connecting blocks 16 on the second connecting plate 12, the second rotating assembly starts to work. The rotating plate 17 rotates in the through hole, and its second meshing tooth 18 meshes with the second gear 14 on the moving assembly, driving the second gear 14 to move the fixed plate 15 up and down. The movement of the fixed plate 15 drives the flusher push-pull head to move inside the flusher housing, so that the interior can fully absorb the atomized disinfection and sterilization gas to achieve internal sterilization.

[0076] 4. Sterilization and air drying:

[0077] After external and internal sterilization is completed, each device is returned to its original position.

[0078] The first rotating component is activated again, driving the rotating ring 5 to rotate and move the sterilized rinsing device into the upper chamber 1. The air-drying component inside the upper chamber 1 is activated to air-dry the rinsing device to ensure that there is no residual liquid.

[0079] 5. Loop processing:

[0080] Repeat the above steps to sterilize the next batch of rinsers. Throughout the process, the equipment operates automatically, which greatly improves production efficiency and ensures the comprehensive sterilization effect of the rinsers.

[0081] The working principle of this invention is as follows: When in use, the flushing device is first placed between every two connecting plates 8. Then, the edge of the flushing device housing is fixed by a fixing assembly, allowing multiple flushing devices to be fixed, thus improving work efficiency. Next, the first rotating assembly drives the first gear 3 to rotate, which in turn drives the first meshing teeth 6 to rotate the rotating ring 5 inside the arc-shaped groove 4. This causes the rotating ring 5 to align the fixing ring 7 with the second connecting plate 12. Then, the atomizing assembly allows the disinfectant liquid to enter the atomizing nozzle 9, allowing the atomized gas to enter the lower housing 2. The atomized gas guiding assembly then sprays the atomized gas onto the flushing device to disinfect and sterilize its outer surface. Simultaneously, the telescopic assembly moves the first connecting plate 10, which... The connecting rod 11 drives the second connecting plate 12 and the second rotating assembly to move. When the second rotating assembly moves to the limit groove on the two connecting blocks 16, the second rotating assembly drives the rotating plate 17 to rotate. The rotating plate 17 drives the second meshing tooth 18 to rotate the second gear 14. The second gear 14 drives the moving assembly to move the fixed plate 15 up and down, so that the push-pull head of the flusher moves inside the flusher housing and draws in the atomized disinfection gas to disinfect the inside of the flusher. After disinfection, each device returns to its original position. Then, the first rotating assembly drives the first gear 3 to rotate the rotating ring 5, so that the disinfected flusher moves into the upper housing 1. Then, the air-drying assembly dries the flusher. This process is repeated. This device can not only fix multiple rinsers for sterilization at the same time, greatly improving production efficiency, but also ensure that all external parts of the rinser can be evenly sterilized by atomized gas through the rotation of the rotating ring 5; while the movement of the rinser push-pull head can also fully absorb the atomized disinfecting gas inside, achieving comprehensive sterilization inside and out.

[0082] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
