Description

Technical Field

[0001] This utility model relates to the technical field of injection fluid filtration equipment, and in particular to an adjustable radioactive injection fluid filtration equipment. Background Technology

[0002] Radioactive injection solutions are widely used in nuclear medicine diagnosis and treatment, and their purity directly affects the diagnostic and treatment outcomes and patient safety. The presence of tiny particles, foreign matter, or degradation impurities in the injection solution may not only cause adverse reactions such as venous thrombosis, but also lead to the deposition of radioactive materials in non-target tissues, affecting diagnostic accuracy and increasing radiation risks.

[0003] To this end, patent CN219209120U discloses a filtration device for producing Xuesaitong injection solution, including a filter box. An inlet pipe is fixed to the left side of the top surface of the filter box, and an outlet pipe is fixed to the bottom right side of the filter box. The filter box is equipped with a filtration mechanism, which includes multiple fixing plates. These fixing plates are staggered and fixed to the inner top and bottom walls of the filter box. A filter screen is snapped onto the front of each fixing plate, and a fixing box is fixed to the front of the filter screen. By providing a filtration mechanism and multiple fixing plates, Xuesaitong injection solution can undergo multiple filtrations, ensuring filtration efficiency and improving filtration quality. Simultaneously, a rotating threaded rod can push two movable blocks to opposite sides via a moving block, allowing the locking block to be pulled out of the slot, enabling quick removal of the filter screen for easy cleaning and ensuring optimal filtration. During installation, the filter screen is simply inserted into the fixing slot.

[0004] The aforementioned filtration equipment for producing Xuesaitong injection solution uses multiple filters with fixed pore sizes to achieve multiple filtrations during use. However, the pore size of the filters is not adjustable, making it unable to meet diverse filtration needs. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable radioactive injection filtration device to address the shortcomings of existing filtration devices for the production of Xuesaitong injection, which are not easily adjustable.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adjustable radioactive injection solution filtration device, including a housing;

[0007] A box door is installed on one side of the box body, a feed pipe is fixed at the top end of the box body, a discharge pipe is fixed at the bottom end of the box body, and an adjusting structure is arranged inside the box body. The adjusting structure comprises a support frame fixed inside the box body, sliding grooves are formed on both sides of the top end of the support frame, a sliding plate is installed at the top end of the support frame, connecting plates are fixed on both sides of the sliding plate, a sliding block is fixed at the bottom end of the connecting plate, a handle is fixed on one side of the sliding plate, and filtering holes are uniformly arranged inside the sliding plate;

[0008] A filtering structure is fixed inside the box body at the bottom end of the sliding plate, and supporting legs are fixed at the edge positions of the bottom end of the box body.

[0009] Preferably, a partition plate is fixed on one side of the top end of the support frame, a guide groove is formed at the bottom end of the partition plate, an adjusting plate is installed at the top end of the sliding plate, a guide block is fixed on one side of the top end of the adjusting plate, a rack is fixed on one side of the adjusting plate, a gear is installed at the top end of the rack, a rotating shaft is fixed at one end of the gear, and a servo motor is fixed at one end of the rotating shaft on one side of the box body.

[0010] Preferably, the support frame is arranged in a "C" shape, the sliding grooves are symmetrically distributed on both sides of the top end of the support frame, the cross sections of the sliding groove and the sliding block are both arranged in an inverted "T" shape, the outer side of the sliding block is fitted with the inner side of the sliding groove, and the sliding block and the support frame form a sliding connection through the sliding groove.

[0011] With the above structure, during use, the sliding groove with an inverted T-shaped cross section is precisely fitted with the sliding block, which can effectively limit the vertical displacement, prevent the sliding plate from loosening during sliding or filtering operations, and ensure the operation stability of the equipment.

[0012] Preferably, the adjusting plates are distributed at equal intervals on the top end of the sliding plate, the width of the adjusting plate is the same as the diameter of the filtering hole, the guide block and the partition plate form a sliding connection through the guide groove, and the gear is in meshed connection with the rack.

[0013] With the above structure, during use, the adjusting plates are distributed at equal intervals and their width is consistent with the diameter of the filtering holes, so that the filtering holes can be accurately blocked or opened when sliding. Combined with the meshing transmission of the gear and the rack, the precise adjustment of the opening and closing area of the filtering holes is realized, so as to meet the impurity interception requirements of different radioactive injection solutions.

[0014] Preferably, the filtration structure includes a first guide frame fixed inside the housing, a first through groove at the bottom of the first guide frame, a ceramic filter element inside the first through groove, a limiting clamp installed on the outside of the ceramic filter element, movable plates fixed on both sides of the limiting clamp, mounting plates installed on both sides inside the housing, an electric push rod installed at the bottom of each mounting plate, and a second guide frame fixed inside the housing at the bottom of the first guide frame, with a second through groove at the bottom of the second guide frame.

[0015] Preferably, the first through groove is circular, the outer side of the ceramic filter element is fitted with the inner side of the first through groove, the interior of the ceramic filter element is uniformly provided with through holes, and the top of the ceramic filter element is hemispherical.

[0016] With the above structure, the uniform flow of medicine can be achieved through the uniform through holes inside the ceramic filter element during use, ensuring full utilization of the filtration area and improving the efficiency of impurity removal. The hemispherical design at the top can guide the rapid dispersion and flow of medicine, reduce the local accumulation of impurities on the filter element surface, and reduce the resistance of medicine flow. Combined with the uniform through holes, the filtration process is smoother and more efficient.

[0017] Preferably, the diameter of the limiting clamp is larger than the diameter of the first through groove, the moving plates are symmetrically distributed on both sides of the limiting clamp, the output end of the electric push rod is fixedly connected to the top of the moving plate, and the second through groove is connected to the inside of the discharge pipe.

[0018] With the above structure, the ceramic filter element can be securely fixed from the outside by the limiting clamp during use, preventing the filter element from falling out of the channel due to the impact of the liquid during filtration, thus ensuring the stability of the filtration structure. In addition, the symmetrically distributed moving plates, together with the electric push rod drive, can drive the limiting clamp and the filter element to rise and fall synchronously, realizing the automatic movement and positioning of the filter element.

[0019] The adjustable radioactive injection solution filtration device provided by this utility model has the following advantages:

[0020] With an adjustable structure, the servo motor drives the gear and rack transmission to make the adjusting plate slide along the guide groove. Combined with the size matching design of the adjusting plate and the filter hole, the actual opening and closing area of ​​the filter hole can be accurately changed to achieve targeted interception of impurities of different particle sizes and meet diverse filtration needs. The slide plate achieves sliding connection through the interlocking structure of the slider and the support frame slide groove. With the handle design, it is easy to install and disassemble quickly and reduce the difficulty of cleaning and maintenance.

[0021] With a filter structure and a ceramic filter element fixed by a limiting clamp, the filter element can be moved up and down by activating an electric push rod, making it easy to replace and clean. The ceramic filter element achieves deep filtration using its own uniform micropores. At the same time, the ceramic material has high stability, avoiding reaction with radioactive injection solutions. The design of the filter element being able to move slightly reduces the "filtration dead zone" formed by the accumulation of impurities. Meanwhile, the guiding and converging effect of the double guide frame ensures that the filtration process is continuous and without stagnation. Attached Figure Description

[0028] 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.

[0029] Please see Figures 1-5 The present invention provides an adjustable radioactive injection solution filtration device, comprising a housing 1.

[0030] Reference Figures 1-4 as shown, a box door 2 is mounted on one side of the box body 1, a feeding pipe 3 is fixed at the top end of the box body 1, a discharging pipe 4 is fixed at the bottom end of the box body 1, an adjusting structure 5 is arranged inside the box body 1, the adjusting structure 5 comprises a support frame 501 fixed inside the box body 1, sliding grooves 502 are arranged on both sides of the top end of the support frame 501, a sliding plate 503 is mounted at the top end of the support frame 501, connecting plates 504 are fixed on both sides of the sliding plate 503, a sliding block 505 is fixed at the bottom end of the connecting plate 504, a handle 506 is fixed on one side of the sliding plate 503, filter holes 507 are uniformly arranged inside the sliding plate 503, a partition plate 508 is fixed on one side of the top end of the support frame 501, a guide groove 509 is arranged at the bottom end of the partition plate 508, an adjusting plate 510 is mounted at the top end of the sliding plate 503, a guide block 511 is fixed on one side of the top end of the adjusting plate 510, a rack 512 is fixed on one side of the adjusting plate 510, a gear 513 is mounted at the top end of the rack 512, a rotating shaft 514 is fixed at one end of the gear 513, a servo motor 515 is fixed at one end of the rotating shaft 514 on one side of the box body 1, the support frame 501 is arranged in a "C" shape, the sliding grooves 502 are symmetrically distributed on both sides of the top end of the support frame 501, the cross sections of the sliding groove 502 and the sliding block 505 are both arranged in an inverted "T" shape, the outer side of the sliding block 505 is fitted with the inner side of the sliding groove 502, the sliding block 505 and the support frame 501 form a sliding connection through the sliding groove 502, the adjusting plates 510 are distributed at equal intervals at the top end of the sliding plate 503, the width of the adjusting plate 510 is the same as the diameter of the filter hole 507, the guide block 511 and the partition plate 508 form a sliding connection through the guide groove 509, and the gear 513 and the rack 512 are in meshed connection.

[0031] By pushing the sliding plate 503 to make the sliding block 505 slide along the sliding groove 502 at the top end of the support frame 501, the sliding plate 503 can be ensured to move stably, which facilitates the installation and disassembly of the sliding plate 503. By starting the servo motor 515 to drive the rotating shaft 514 to rotate, the gear 513 and the rack 512 are driven to perform meshing transmission, which in turn drives the guide block 511 at the top end of the adjusting plate 510 to slide along the guide groove 509. Since the adjusting plates 510 are distributed at equal intervals and their width matches the diameter of the filter holes 507 on the sliding plate 503, the movement of the adjusting plate 510 can change the actual opening and closing area of the filter holes 507, so as to preset the initial filtration precision. When the injection solution flows through the sliding plate 503, the filter holes 507 with the preset opening degree first intercept large-particle impurities in the injection solution.

[0032] Reference to Figure 2 , Figure 3 and Figure 5As shown, a filter structure 6 is fixed inside the bottom box 1 of the slide plate 503. The filter structure 6 includes a first guide frame 601 fixed inside the box 1. A first through groove 602 is provided at the bottom of the first guide frame 601. A ceramic filter element 603 is provided inside the first through groove 602. A limit clamp 604 is installed on the outside of the ceramic filter element 603. Movable plates 605 are fixed on both sides of the limit clamp 604. Mounting plates 606 are installed on both sides inside the box 1. Electric push rods 607 are installed at the bottom of the mounting plates 606. A second guide frame 608 is fixed inside the bottom box 1 of the first guide frame 601. The bottom end of the guide frame 608 is provided with a second through groove 609. The first through groove 602 is circular. The outer side of the ceramic filter element 603 is fitted with the inner side of the first through groove 602. The ceramic filter element 603 has through holes evenly arranged inside. The top end of the ceramic filter element 603 is hemispherical. The diameter of the limiting clamp 604 is larger than the diameter of the first through groove 602. The moving plate 605 is symmetrically distributed on both sides of the limiting clamp 604. The output end of the electric push rod 607 is fixedly connected to the top end of the moving plate 605. The second through groove 609 is connected to the inside of the discharge pipe 4. Support legs 7 are fixed at the edge of the bottom end of the box body 1.

[0033] The pre-filtered injection solution flows evenly into the ceramic filter element 603 area through the guidance of the first guide frame 601. The ceramic filter element 603 is installed inside the first channel 602 by the limiting clamp 604. The ceramic filter element 603 has a cylindrical structure, and its evenly distributed micropores can deeply trap tiny impurities in the injection solution. At the same time, the stability of the ceramic material is utilized to avoid chemical reaction with the radioactive injection solution. The limiting clamp 604 moves the ceramic filter element 603 up and down by activating the electric push rod 607 and moving the plate 605. According to the viscosity change of the injection solution, the ceramic filter element 603 can be driven to move slightly up and down in the first channel 602 to change the contact area between the injection solution and the filter element, avoiding the accumulation of impurities on the filter element surface to form a "filtration dead zone" and ensuring the continuous and stable filtration process. The injection solution, which has been deeply purified by the ceramic filter element, flows into the discharge pipe 4 through the second channel 609 through the convergence of the second guide frame 608. The second channel 609 is directly connected to the inside of the discharge pipe 4, with no stagnation area during the flow guidance process, effectively reducing the risk of residual radioactive materials.

[0034] 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.
