[0001] This utility model relates to the field of medical liquid filter technology, specifically a re-sterilizable medical liquid filter. Background Technology
[0002] Medical liquid filters can effectively remove impurities and microorganisms from medications and infusions, ensuring the purity and sterility of the liquids and thus protecting patient safety. They are suitable for high-frequency disinfection and reusable filtration equipment, and are especially suitable for medical scenarios that require frequent disinfection, such as hemodialysis equipment and infusion devices. Medical liquid filters play an important role in ensuring the safety and effectiveness of medical fluids.
[0003] Traditional medical liquid filters are not suitable for multiple filtration of the added liquid, requiring replacement after each use. This leads to a high consumption of disposable medical liquid filters, making them inconvenient for areas requiring frequent use. Utility Model Content
[0004] The purpose of this invention is to provide a reusable sterilizable medical liquid filter to solve the problem mentioned in the background art that medical liquid filters are not easy to re-sterilize during use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reusable sterilizable medical liquid filter, comprising a filter body, a filling port, an outlet, a mounting plate, and filter media. The top of the filter body is provided with a filling port, and the end of the filter body away from the filling port is provided with an outlet. A mounting plate is provided on one side of the filter body, and a uniformly distributed filter media is provided on one side of the mounting plate. A locking bolt is threadedly connected between the mounting plate and the filter body. A fixedly connected protective plate is provided inside the filter body, and a through groove is provided on one side of the protective plate.
[0006] Preferably, the filter body has an inclined plate on the side near the protective plate, one end of the inclined plate is connected to a rubber pad, and the end of the inclined plate away from the rubber pad is provided with a rod that is connected to the filter body through a bearing.
[0007] Preferably, a drive motor is installed at one end of the filter body, and the output end of the drive motor is connected to a rotating rod through a coupling. A pulley set is connected between the rotating rod and the rotating shaft.
[0008] Preferably, a collection frame is provided on the side of the filter body near the inclined plate, a suction pump is installed at the top of the collection frame, and a suction pipe is connected to one side of the suction pump.
[0009] Preferably, the end of the suction pump away from the suction pipe is connected to a connecting pipe, and the bottom end of the collection frame is provided with a discharge port.
[0010] Preferably, a built-in sensor is installed at the top of the filter body.
[0011] Preferably, a symmetrically distributed sliding rod is provided on one side of the inside of the collection frame, and a threaded rod is provided on the side of the collection frame away from the sliding rod via a bearing. One end of the threaded rod is connected to a rotating handwheel, and a scraper is connected between the threaded rod and the sliding rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This reusable sterilizable medical liquid filter, by starting the drive motor, enables the rotating rod connected to the output end to rotate the inclined plate through the pulley assembly and the rotating rod, so that the filtered liquid can be repeatedly extracted and thus repeatedly sterilized. By rotating the rotating handwheel, the connected threaded rod can be rotated, which in turn moves the scraper connected to the surface thread, so that the scraper can stably scrape the inner wall of the collection frame, thereby enabling the medical liquid filter to have a better scraping and cleaning effect during use.
[0013] 1. This reusable medical liquid filter addresses the inconvenience of reusing liquids during use. By starting the drive motor, the output rod rotates, which in turn rotates via a pulley system, causing the inclined plate to rotate. This allows the added liquid to pass through the filter media and flow along the protective plate and inclined plate into the collection frame. Then, the suction pump is activated, drawing liquid from the collection frame through a connected suction pipe and returning it to the filter body. This improves the reusability and disinfection of the medical liquid filter during use.
[0014] 2. This reusable sterilizable medical liquid filter often causes impurities to adhere to the inner wall of the collection frame during use, making it inconvenient to use. By rotating the handwheel, the connected threaded rod can be rotated, which in turn moves the scraper connected to the surface. This allows the scraper to move steadily across the surface of the sliding rod, effectively scraping the inner wall of the collection frame and improving the cleaning effect of the medical liquid filter.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 and Figure 2This utility model provides a technical solution: a reusable sterilizable medical liquid filter, comprising a filter body 1, a filling port 2, an outlet port 3, a mounting plate 4, and filter media 5. The filling port 2 is located at the top of the filter body 1, and the outlet port 3 is located at the end of the filter body 1 away from the filling port 2. The mounting plate 4 is located on one side of the filter body 1, and the filter media 5 is evenly distributed on one side of the mounting plate 4. A locking bolt 6 is threadedly connected between the mounting plate 4 and the filter body 1. A protective plate 7 is fixedly connected inside the filter body 1, and a through groove 8 is formed on one side of the protective plate 7. An inclined plate 9 is located on the side of the filter body 1 near the protective plate 7, and one end of the inclined plate 9 is connected to... A rubber pad 10 is provided. A rod 11, which is connected to the filter body 1 via a bearing, is provided through the end of the inclined plate 9 away from the rubber pad 10. A drive motor 12 is installed at one end of the filter body 1. The output end of the drive motor 12 is connected to a rotating rod 13 via a coupling. A pulley group 14 is connected between the rotating rod 13 and the rotating rod 11. A collection frame 15 is provided on the side of the filter body 1 near the inclined plate 9. A suction pump 16 is installed at the top of the collection frame 15. A suction pipe 17 is connected to one side of the suction pump 16. A connecting pipe 18 is connected to the end of the suction pump 16 away from the suction pipe 17. A discharge port 19 is provided at the bottom of the collection frame 15. A built-in sensor 20 is installed at the top of the filter body 1.
[0022] In practice,
[0023] See Figure 1 and Figure 2It is known that when medical liquid filters are in use, it is usually not easy to reuse the liquid, making the use of medical liquid filters inconvenient. By starting the drive motor 12, the drive motor 12 can rotate the rotating rod 13 connected to the output end. When the rotating rod 13 rotates, it can rotate the connected pulley assembly 14. At the same time, when the pulley assembly 14 rotates, it can rotate the connected rotating rod 11. When the rotating rod 11 rotates, it can rotate the connected inclined plate 9. So that after the inclined plate 9 rotates, it can contact the through groove 8 opened on one side of the protective plate 7. This allows the added liquid to be filtered through the filter media 5 and then enter the collection frame 15 along the protective plate 7 and the inclined plate 9. Then the pump is drawn... The suction pump 16 is started, allowing it to draw liquid from the collection frame 15 through the connected suction tube 17. The liquid is then transported back to the filter body 1 through the connecting tube 18. Meanwhile, the built-in sensor 20 installed inside the filter body 1 records the number of repetitions, thereby determining the number of times the filter media 5 has been disinfected and its saturation status. This allows for timely reminders for maintenance and replacement. After the number of repetitions is set by the controller, the drive motor 12 can be restarted, causing the tilting plate 9 to reset. This allows the liquid that has been filtered multiple times to be discharged downwards through the channel 8, and it can also be filtered again through another filter media 5, ensuring that the medical liquid filter has a good repeated disinfection effect during use.
[0024] A symmetrically distributed sliding rod 21 is provided on one side of the inside of the collection frame 15. A threaded rod 22 is provided on the side of the collection frame 15 away from the sliding rod 21 and is rotatably connected by a bearing. One end of the threaded rod 22 is connected to a rotating handwheel 23. A scraper 24 is connected between the threaded rod 22 and the sliding rod 21.
[0025] In practice,
[0026] See Figure 1 , Figure 3 and Figure 4 It is known that when a medical liquid filter is in use, impurities inside often adhere to the inner wall of the collection frame 15, making the medical liquid filter inconvenient to use. By rotating the handwheel 23, the connected threaded rod 22 can be rotated, which in turn moves the scraper 24 connected to the surface. As a result, the scraper 24 can move on the surface of the slide bar 21, allowing it to stably scrape the inner wall of the collection frame 15, thus enabling the medical liquid filter to have a better scraping and cleaning effect during use.
[0027] In summary, the liquid filter effectively removes impurities and microorganisms from medications and infusions, ensuring the purity and sterility of the liquid and thus protecting patient safety. By starting the drive motor 12, the drive motor 12 rotates the rotating rod 13 connected to the output end, so that the rotating rod 13 rotates the rotating rod 11 through the pulley group 14, thereby rotating the inclined plate 9. This allows the added liquid to be filtered through the filter material 5 and then enter the collection frame 15 along the protective plate 7 and the inclined plate 9. Then, the suction pump 16 is started, so that the suction pump 16 can draw the liquid inside the collection frame 15 through the connected suction tube 17, and then transport it back into the filter body 1 along the connecting tube 18. This allows the medical liquid filter to have a good repeated disinfection effect during use. The contents not described in detail in this description are existing technologies known to those skilled in the art.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
