Abstract
Description
Technical Field
[0001] This utility model relates to the field of serum extraction technology, specifically a serum filtration device. Background Technology
[0002] In some laboratory experiments, small amounts of material or serum, such as 10 ml, are required for filtration before further experimental research. To simulate real production conditions, filter membranes that are consistent with the production process are selected as much as possible. However, the filtration devices available on the market are either microporous membranes of fixed materials (which cannot completely simulate the target filter membrane scenario) or have requirements on the amount of serum to be filtered (for example, a 47 mm flat plate filter requires a volume of more than 50 ml for relatively effective filtration). Currently, there is no device specifically designed for filtering and extracting small amounts of material or serum. Therefore, a serum filtration device is proposed to address the above issues. Utility Model Content
[0003] The purpose of this invention is to provide a serum filtration device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] As an optional embodiment of the serum filtration device described in this utility model, the serum filtration device includes a chassis, a mounting platform, and a placement platform;
[0006] A mounting platform is fixedly connected to the top of the chassis, and a placement platform is fixedly connected above the mounting platform. Test tubes are installed inside the placement platform.
[0007] A protective sleeve is provided above the test tube, and a hydraulic rod is fixedly connected inside the protective sleeve. A connecting plate is fixedly connected to the outside of the free end of the hydraulic rod. A cover plate is fixedly connected to one end of the connecting plate. A placement groove is opened in the center of the cover plate. A pressure applying mechanism is spirally connected to the cover plate through the placement groove.
[0008] The protective sleeve has a through hole in the center and an annular groove on the top.
[0009] As an optional embodiment of the serum filtration device described in this utility model, the free end of the hydraulic rod is slidably connected to the protective sleeve, and the inner diameter of the protective sleeve is consistent with the outer diameter of the mounting platform.
[0010] As an optional embodiment of the serum filtration device described in this utility model, a pressure ring is fixedly connected to the bottom of the cover plate, and the pressure ring is protruding.
[0011] As an optional embodiment of the serum filtration device of this utility model, the inner wall of the placement groove is inclined and the placement groove is conical.
[0012] In some laboratory experiments, small amounts of material or serum, such as 10 ml, are required for filtration before further experimental research. To simulate real production conditions, filter membranes with the same production process are selected as much as possible. However, currently available filtration devices are either microporous membranes of fixed materials or have requirements on serum filtration volume. There is currently no device specifically designed for filtering and extracting small amounts of material or serum. In this method, an external power supply is connected, the flat filter membrane is cut, and placed on top of the protective cover. The hydraulic rod is then activated to move the connecting plate and cover plate. The pressure ring under the cover plate engages with the annular groove to fix the filter membrane. The syringe for extracting the material is then placed inside the pressure mechanism, which is connected to the cover plate. Activating the pressure mechanism applies pressure to the syringe, facilitating pressurized filtration of the material. Even for small amounts of material / serum, such as 5 or 10 ml, the target filter membrane can be freely selected and cut to the desired size, making it very convenient to use.
[0013] As an optional solution of the serum filtration device of this utility model, the pressure applying mechanism includes a fixed frame, a motor and a threaded shaft. The motor is fixedly connected inside the fixed frame, the threaded shaft is fixedly connected to the end of the motor's main shaft, and a threaded sleeve is screwed to the outside of the threaded shaft.
[0014] The bottom of the fixed frame is fixedly connected to an installation sleeve, and the outer side of the installation sleeve is spirally connected to the cover plate.
[0015] As an optional embodiment of the serum filtration device of this utility model, the outer side of the threaded sleeve is provided with a sliding groove, and the threaded sleeve is slidably connected to a movable block through the sliding groove, and the outer side of the movable block is fixedly connected to the fixed frame.
[0016] Furthermore, the bottom of the syringe is generally set at an angle. In this case, the placement groove can be used to fix the syringe. By starting the motor, the threaded shaft is driven to move, and the threaded shaft drives the threaded sleeve to move. At this time, the moving end of the syringe can be applied to make the material inside it smoothly discharged. The moving block is set to ensure the stable movement of the threaded sleeve.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] In use, the flat filter membrane is cut and placed on top of the protective sleeve. Then, the connecting plate and cover plate are moved by activating the hydraulic rod. The lower pressure ring under the cover plate can then cooperate with the annular groove to fix the filter membrane. Then, the syringe for extracting material is placed inside the pressure mechanism and connected to the cover plate. Activating the pressure mechanism will then apply pressure to the syringe, facilitating pressure filtration of the material. This method is suitable for filtering small amounts of material / serum, even as little as 5-10 ml.
[0019] Furthermore, the bottom of the syringe is generally set at an angle. In this case, the placement groove can be used to fix the syringe. By starting the motor, the threaded shaft is driven to move, and the threaded shaft drives the threaded sleeve to move. At this time, the moving end of the syringe can be applied to make the material inside it smoothly discharged. The moving block is set to ensure the stable movement of the threaded sleeve.

[0025] 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.
[0026] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution:
[0027] A serum filtration device includes a chassis 1, a mounting platform 2, and a placement platform 3;
[0028] The top of the chassis 1 is fixedly connected to the mounting platform 2, and the top of the mounting platform 2 is fixedly connected to the placement platform 3. The placement platform 3 is equipped with test tubes 4.
[0029] A protective sleeve 5 is provided above the test tube 4, and a hydraulic rod 7 is fixedly connected inside the protective sleeve 5. A connecting plate 12 is fixedly connected to the outside of the free end of the hydraulic rod 7. A cover plate 8 is fixedly connected to one end of the connecting plate 12. A placement groove 11 is provided in the center of the cover plate 8. A pressure applying mechanism 9 is spirally connected to the cover plate 8 through the placement groove 11.
[0030] The protective sleeve 5 has a through hole in the center and an annular groove 6 on the top.
[0031] The outer side of the free end of the aforementioned hydraulic rod 7 is slidably connected to the protective sleeve 5, and the inner diameter of the aforementioned protective sleeve 5 is consistent with the outer diameter of the mounting platform 2.
[0032] The bottom of the cover plate 8 is fixedly connected to a pressure ring 10, and the pressure ring 10 is protruding.
[0033] The inner wall of the aforementioned placement groove 11 is inclined, and the aforementioned placement groove 11 is conical.
[0034] In some laboratory experiments, small amounts of material or serum, such as 10ml, are required for filtration before further experimental research. To simulate real production conditions, filter membranes that are consistent with the production process are selected as much as possible. However, the filtration devices available on the market are either microporous membranes of fixed materials that cannot fully simulate the target filter membrane scenario, or the filtration devices have requirements on the amount of serum to be filtered. For example, a 47mm flat plate filter requires a volume of more than 50ml to be relatively effective. Currently, there is no device specifically designed for filtering and extracting small amounts of material or serum. When in use, an external power supply is connected, the flat plate filter membrane is cut, and it is placed on top of the protective sleeve 5. At this time, the hydraulic rod 7 is activated to move the connecting plate 12 and the cover plate 8. The pressure ring 10 under the cover plate 8 can then cooperate with the annular groove 6 to fix the filter membrane. Then, the syringe for extracting the material is placed inside the pressure mechanism 9, and the pressure mechanism 9 is connected to the cover plate 8. At this time, the pressure mechanism 9 is activated to apply pressure to the syringe, which facilitates pressure filtration of the material. This is useful for filtering small amounts of material / serum, even as little as 5 or 10ml.
[0035] In this embodiment, the pressure ring 10 can be inserted into the annular groove 6 to fix the cut filter membrane. The material filtered under pressure can fall smoothly into the test tube 4 for centralized collection. The placement groove 11 inside the cover plate 8 is provided with threads for connection with the pressure mechanism 9. The lower part of the placement groove 11 is set in an inclined conical shape, which is used to cooperate with the inclined surface of the bottom of the syringe to fix the syringe.
[0036] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 3 Specifically, the pressure applying mechanism 9 includes a fixed frame 901, a motor 902 and a threaded shaft 903. The motor 902 is fixedly connected inside the fixed frame 901, the threaded shaft 903 is fixedly connected to the end of the main shaft of the motor 902, and a threaded sleeve 904 is screwed to the outside of the threaded shaft 903.
[0037] The bottom of the aforementioned fixed frame 901 is fixedly connected to a mounting sleeve 906, and the outer side of the mounting sleeve 906 is spirally connected to the cover plate 8.
[0038] The threaded sleeve 904 has a sliding groove on its outer side, and the threaded sleeve 904 is slidably connected to a moving block 905 through the sliding groove. The outer side of the moving block 905 is fixedly connected to the fixed frame 901.
[0039] Furthermore, the bottom of the syringe is generally inclined. At this time, the placement groove 11 can be used to fix the syringe. By starting the motor 902, the threaded shaft 903 is moved, and the threaded shaft 903 moves the threaded sleeve 904. At this time, the moving end of the syringe can be applied to make the material inside it smoothly discharged. The moving block 905 is used to ensure the stable movement of the threaded sleeve 904.
[0040] In this embodiment, when the threaded sleeve 904 squeezes the syringe, the movable block 905 provided therein can cooperate with the threaded sleeve 904 to ensure its stable up and down movement.
