Description

Technical Field

[0001] This utility model belongs to the field of medical filter membrane technology, specifically relating to a medical filter membrane X-ray filtration effect simulation testing device. Background Technology

[0002] Using X-rays to examine diseases is a common clinical diagnostic method both domestically and internationally. Among various high-precision medical equipment in hospitals, medical X-ray diagnostic equipment (hereinafter referred to as X-ray machines) is the earliest and most widely used medical imaging examination method. When X-rays irradiate a living organism, they may cause cancer and organ damage. Therefore, the issue of X-ray ionization damage has received increasing attention, making the safe and effective protection against medical X-rays particularly important. Using a filter membrane on the X-ray machine's exit window can effectively reduce the output of soft X-rays and lower the radiation dose received by the human body. According to the interaction mechanism between X-rays and matter, when using a single metal filter membrane to filter soft X-rays, the thicker the membrane, the better the absorption effect of soft X-rays. However, at the same time, it will also absorb some hard X-rays, thus affecting the imaging effect and quality. Therefore, in order to minimize the impact on imaging quality, the filter membrane often cannot be made very thin, resulting in a very unsatisfactory absorption effect of soft X-rays. Therefore, researching how to increase the absorption effect of soft X-rays while ensuring the transmittance of hard X-rays and guaranteeing the quality of X-ray imaging has become an important topic of increasing concern for many scholars at home and abroad. As a result, it is necessary to test the X-ray filtration effect of medical filter membranes.

[0003] Traditional fixed-position irradiation testing methods for medical filter membrane X-ray filtration effect simulation devices have significant shortcomings: First, the test specimens are placed in an open radiation zone before testing, making it difficult to move and replace them in a timely manner during the test, requiring machine downtime and increasing working time; Second, to facilitate the placement of test specimens, they are often placed horizontally, leaving the vertical positions mostly free and unconstrained, making it difficult to stack and conduct composite tests, thus reducing the scope of testing and lowering the overall effectiveness of the medical filter membrane X-ray filtration effect simulation testing device.

[0004] In summary, in order to improve the continuity and efficiency of X-ray filtration effect testing of medical filter membranes, it is necessary to solve the problem of long downtime for single-set loading and continuous loading, so that medical filter membranes can be moved, docked and combined for testing quickly and stably. Utility Model Content

[0005] The present invention provides a medical filter membrane X-ray filtration effect simulation testing device, which aims to solve the problem that traditional medical filter membrane X-ray filtration effect simulation testing requires a long loading time for moving filter membranes and is difficult to conduct continuous and multi-combination tests.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical filter membrane X-ray filtration effect simulation testing device, comprising a support box, a cover plate body installed at the upper end of the support box, a buckle seat fixed to the rear end of the support box, a limiting tube installed at the upper end of the cover plate body, a support frame disposed on one side of the buckle seat, a receiving box for storing and moving the medical filter membrane installed at the front end of the buckle seat, a first limiting groove opened at the front and rear of the inner side of the receiving box, a buckle body fixed to the rear end of the receiving box, a fixing plate installed at the lower end of the receiving box, and an extension plate installed at the upper end of the fixing plate. The device includes a telescopic rod, a support plate mounted on the upper end of the telescopic rod, a support spring disposed between the support plate and the fixed plate, a first push plate slidably connected to the upper end of the receiving box, a first docking rod fixed to one side of the first push plate, an identification ring slidably connected inside the receiving box for marking the filter membrane specifications, a positioning ring disposed outside the identification ring for loading and positioning the medical filter membrane, a pushing assembly disposed on one side of the receiving box, and a positioning structure disposed on the other side of the receiving box for positioning the medical filter membrane during testing. The buckle body is slidably connected to the buckle seat, and the pushing assembly is used to push the first push plate and the first docking rod to move.

[0007] In a preferred embodiment, the pushing component includes a first hydraulic push rod mounted on the lower end of the support frame, a movable frame fixed to the output end of the first hydraulic push rod, the movable frame being slidably connected to the support frame, and the upper end of the movable frame being slidably connected to a first docking rod. The first hydraulic push rod is used to drive the movable frame and the first push plate to move along a predetermined path.

[0008] In a preferred embodiment, a receiving frame is fixedly connected to one side of the support box, a collection box is slidably connected to the inner side of the receiving frame, and an installation platform is provided at the upper end of one side of the support box.

[0009] In a preferred embodiment, a fixing screw is installed at the upper end of the mounting platform, a rotating block is threaded to the outer side of the fixing screw, a rotating frame is rotatably connected to the lower end of the rotating block, and mounting frames are fixed to both sides of the rotating frame.

[0010] In a preferred embodiment, the positioning structure includes a detection frame disposed on the other side of the receiving box, a second limiting groove formed at the front and rear of the detection frame, a second push plate slidably connected to the lower end of the detection frame, a second connecting rod fixed to the outside of the second push plate, and a lifting assembly disposed at the lower end of the detection frame.

[0011] In a preferred embodiment, a second hydraulic push rod is provided on the outer side of the testing frame. The output end of the second hydraulic push rod is fixedly connected to the testing frame. The second hydraulic push rod is used to drive the testing frame to move along a predetermined path. The second hydraulic push rod is installed at the lower end of the mounting platform.

[0012] In a preferred embodiment, the lifting assembly includes a third hydraulic push rod mounted on the upper end of the testing frame and a lifting plate fixed to the output end of the third hydraulic push rod.

[0013] In a preferred embodiment, a threaded tube is fixedly connected to the lower end of the lifting plate, a fixing block is threadedly connected to the outer side of the threaded tube, and positioning frames are fixedly connected to both sides of the upper end of the lifting plate.

[0014] The beneficial effects of this utility model are as follows: 1. By working together with the receiving box and the pushing structure, the placement loading mode is changed, so that the medical filter membrane can be continuously and stably delivered into the simulation test area for testing during loading. This reduces the time required to move the medical filter membrane in batches and ensures the stability of the docking. It solves the problem that the loading time is long when testing different medical filter membranes, and facilitates continuous testing.

[0015] 2. The medical filter membrane is received for testing through a positioning structure, which facilitates testing. Multiple sets of medical filter membranes are positioned through a long pipe and lifting structure, which allows for the combination and testing of multiple medical filter membranes, increases the testing content, improves the overall filtration effect, reduces the requirements for the specifications and materials of medical filter membranes, lowers the overall cost, and improves the effectiveness of using medical filter membranes.

[0016] 3. The lifting and pushing structures facilitate the discharge of the medical filter membrane after testing from the positioning structure, and the lifting structure positions the detection probe. This allows for control of the number and thickness of the stacked medical filter membranes while protecting the monitoring probe, thus facilitating control of the simulated X-ray environment, improving testing accuracy, and reducing interference.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Refer to the instruction manual appendix Figures 1 to 7 A medical filter membrane X-ray filtration effect simulation testing device includes a support box 1, a cover plate body 2 installed at the upper end of the support box 1, a buckle seat 5 fixed to the rear end of the support box 1, a limiting tube 6 installed at the upper end of the cover plate body 2, a support frame 12 disposed on one side of the buckle seat 5, a container 15 installed at the front end of the buckle seat 5 for storing and moving the medical filter membrane, a first limiting groove 16 formed at the front and rear of the inner side of the container 15, a buckle body 17 fixed to the rear end of the container 15, a fixing plate 18 installed at the lower end of the container 15, a telescopic rod 19 installed at the upper end of the fixing plate 18, and a device for simulating the X-ray filtration effect of a medical filter membrane installed at the upper end of the telescopic rod 19. The container includes a support plate 20, a support spring 21 disposed between the support plate 20 and the fixing plate 18, a first push plate 22 slidably connected to the upper end of the receiving box 15, a first docking rod 23 fixed to one side of the first push plate 22, an identification ring 24 slidably connected inside the receiving box 15 for identifying the filter membrane specifications, a positioning ring 25 disposed outside the identification ring 24 for loading and positioning the medical filter membrane, a push assembly disposed on one side of the receiving box 15, and a positioning structure disposed on the other side of the receiving box 15 for positioning the medical filter membrane during testing. The buckle body 17 is slidably connected to the buckle seat 5, and the push assembly is used to push the first push plate 22 and the first docking rod 23 to move.

[0027] It should be noted that this device uses the support box 1 and the cover plate body 2 as the main load-bearing and protective structures. Holes for pipeline installation are opened below the support box 1 and on the side wall panels, and radiation-shielding lead plates are inserted inside the wall panels and the front door. Meanwhile, the front end of the receiving box 15 is equipped with a handle for movement, and the receiving box 15 can be installed via the buckle seat 5 and the buckle body 17. Before testing, the medical filter membrane is installed via the positioning ring 25 and fixed with two connecting ears. The specifications and materials are marked on the corresponding identification ring 24. The fixing plate 18 is removed, facilitating the placement of the positioning ring 25 and identification ring 24 inside the receiving box 15 in the order of "positioning ring 25 - identification ring 24 - positioning ring 25 - identification ring 24...". This allows the medical filter membrane to be tested to be placed before testing, and the fixing plate 18 and support plate 20 are installed for positioning and sealing. During operation, the positioning ring 25 and medical filter membrane are moved by pushing the assembly, and the positioning structure supports the medical filter membrane to be tested, facilitating continuous and combined testing. The upper end of the receiving box 15 has a hole with the same outer diameter as the identification ring 24, allowing the identification ring 24 to pass through the receiving box 15 and enter the limiting tube 6 for easy user identification. The upper end of the receiving box 15 also has square holes on both sides for the movement of the positioning ring 25, and the filter membrane is constrained by the connecting ears and the first limiting groove 16 to prevent misalignment. During movement, the medical filter membrane and the positioning ring 25 are supported by the support spring 21 and the telescopic rod 19 to adhere to the upper inner side of the receiving box 15, facilitating discharge from the side square holes.

[0028] Refer to the instruction manual appendix Figure 2 and Figure 4 The pushing component includes a first hydraulic push rod 13 installed at the lower end of the support frame 12 and a movable frame 14 fixed to the output end of the first hydraulic push rod 13. The movable frame 14 is slidably connected to the support frame 12, and the upper end of the movable frame 14 is slidably connected to the first docking rod 23. The first hydraulic push rod 13 is used to drive the movable frame 14 and the first push plate 22 to move along a predetermined path.

[0029] Another alternative embodiment based on the push component design: the hydraulic transmission of the push component can be replaced with a "servo motor-synchronous belt-electromagnetic coupling" transmission structure. Specifically, this includes a high-rigidity linear guide rail fixed to the support frame 12, a linear slider fixed to the moving frame 14, an active and driven synchronous pulleys mounted at both ends of the support frame 12, an annular synchronous belt fitted onto the two pulleys, and a servo motor driving the active synchronous pulley. The moving frame 14 is fixed to the synchronous belt via a connector. Furthermore, permanent magnets and electromagnets are respectively installed at corresponding positions on the end of the first docking rod 23 and on the moving frame 14, forming an electromagnetic coupler. During operation, the servo motor drives the synchronous belt, causing the moving frame 14 to move precisely along the linear guide rail; when docking is required, the electromagnet is energized to generate magnetic attraction, automatically attracting and locking the first docking rod 23. Compared to hydraulic transmission, this structure offers faster dynamic response, a wider speed adjustment range (5-150 mm / s), and eliminates wear and wobbling caused by lateral forces that may exist in hydraulic cylinders through the high-precision guidance of the guide rail slider. Synchronous belt drives offer low noise, require no lubrication, and are easier to maintain. Electromagnetic coupling enables automatic and non-destructive docking and disengagement, avoiding wear and alignment errors caused by mechanical sliding friction. This structure is particularly suitable for high-throughput laboratory scenarios requiring rapid cycling and alternating testing of multiple filter membrane specifications, significantly improving test cycle time and automation.

[0030] It should be noted that when the housing 15 is installed in place, sliding occurs between the movable frame 14 and the first docking rod 23, and they are fixed by friction docking. Then, the first hydraulic push rod 13 is used to drive the movable frame 14 to move back and forth on the support frame 12, thereby driving the first push plate 22 and the first docking rod 23 to move back and forth. The first push plate 22 pushes the positioning ring 25 and the medical filter membrane to move into the positioning assembly.

[0031] Refer to the instruction manual appendix Figure 2 A support frame 3 is fixedly connected to one side of the support box 1, and a collection box 4 is slidably connected to the inner side of the support frame 3. An installation platform 7 is provided at the upper end of one side of the support box 1.

[0032] It should be noted that after testing a single medical filter membrane, if the membrane is not needed for further testing immediately, it can be removed from the positioning assembly. After the medical filter membrane and positioning ring 25 are moved out of the positioning structure, they are collected by the collection box 4. The tested medical filter membrane is then collected by the receiving frame 3 and the collection box 4, facilitating operations such as recycling, marking, and retesting, and preventing an excessive number of medical filter membranes in the positioning assembly or interference with the test results.

[0033] Refer to the instruction manual appendix Figure 3A fixing screw 8 is installed at the upper end of the mounting platform 7. A rotating block 9 is threadedly connected to the outer side of the fixing screw 8. A rotating frame 10 is rotatably connected to the lower end of the rotating block 9. Mounting frames 11 are fixedly connected to both sides of the rotating frame 10.

[0034] It should be noted that the X-ray emission structures of the X-ray diffractometer and the X-ray machine are respectively mounted on the two mounting brackets 11, and the rotating frame 10 is driven to rise and fall by the fixed screw 8 and the rotating block 9. The rotating frame 10 and the mounting bracket 11 can be rotated independently, thereby changing the X-ray source connected to the positioning component, thus simulating different environments, and finally being fixed by thread extrusion through the mounting table 7, the fixed screw 8 and the rotating block 9.

[0035] Refer to the instruction manual appendix Figure 6 and Figure 7 The positioning structure includes a detection frame 26 disposed on the other side of the receiving box 15, a second limiting groove 28 opened at the front and rear inside the detection frame 26, a second push plate 29 slidably connected to the lower end of the detection frame 26, a second docking rod 30 fixed to the outside of the second push plate 29, and a lifting assembly disposed at the lower end of the detection frame 26.

[0036] It should be noted that square holes are provided at both the upper and lower ends of the testing frame 26. The lower square hole is slightly higher to facilitate the passage of the medical filter membrane and the positioning ring 25. The testing frame 26 and the second limiting groove 28 accommodate and position the medical filter membrane and the positioning ring 25. At the same time, it facilitates the docking or movement of the medical filter membrane and the positioning ring 25 with the X-ray source, ensuring that the gap between the X-ray source and the medical filter membrane is fixed, and ensuring that the simulation effect and the test variables are fixed. The second push plate 29 and the second docking rod 30 dock with the moving frame 14, which facilitates the second push plate 29 to push out the medical filter membrane and the positioning ring 25 that do not need to be tested.

[0037] Refer to the instruction manual appendix Figure 6 and Figure 7 A second hydraulic push rod 27 is provided on the outer side of the testing frame 26. The output end of the second hydraulic push rod 27 is fixedly connected to the testing frame 26. The second hydraulic push rod 27 is used to drive the testing frame 26 to move along a predetermined path. The second hydraulic push rod 27 is installed at the lower end of the mounting platform 7.

[0038] It should be noted that the second hydraulic push rod 27 drives the test frame 26 to move within a small range, so that the square holes of the receiving box 15 and the test frame 26 are aligned or offset, thereby controlling the test frame 26 to be closed and ensuring that the gap between the X-ray source and the medical filter membrane is fixed, preventing interference from the other medical filter membrane and the positioning ring 25 during the test.

[0039] Refer to the instruction manual appendix Figure 6The lifting assembly includes a third hydraulic push rod 31 mounted on the upper end of the detection frame 26 and a lifting plate 32 fixed to the output end of the third hydraulic push rod 31.

[0040] It should be noted that the X-ray detector probe is installed on the lifting plate 32 to receive X-rays after they pass through the medical filter membrane and to judge the X-ray filtration effect, which is convenient for judging the working status of the medical filter membrane. The third hydraulic push rod 31 drives the lifting plate 32 to rise and fall, which facilitates the raising and lowering of the medical filter membrane and the positioning ring 25.

[0041] Another alternative embodiment based on the lifting component design: the hydraulic transmission of the lifting component can be replaced with a "servo motor-ball screw-linear guide" transmission structure. Specifically, this includes a vertical linear guide fixed inside the testing frame 26, a guide rail slider fixedly connected to the lifting plate 32, a ball screw vertically installed inside the testing frame 26, a lifting connecting block fixedly connected to the ball screw nut, and a servo motor driving the ball screw to rotate. The servo motor is connected to the upper end of the ball screw via a coupling, and the lifting plate 32 is simultaneously fixed to both the guide rail slider and the lifting connecting block. During operation, the servo motor drives the ball screw to rotate precisely, and the rotational motion is converted into vertical linear motion of the lifting plate 32 along the linear guide through the nut. Compared to hydraulic transmission, this structure has higher transmission chain rigidity and lower frictional resistance, enabling more precise displacement and speed control, with a positioning accuracy of ±0.02mm. It effectively avoids the crawling and drifting phenomena that may exist in hydraulic systems, ensuring the absolute constancy of the test gap. Both the ball screw and linear guide adopt a dustproof and sealed design. Combined with the closed-loop position control of the servo motor, it can maintain transmission accuracy and stability for a long time. It is especially suitable for precision experimental scenarios that require repeated testing at multiple intervals and heights, significantly improving testing efficiency and data consistency.

[0042] Refer to the instruction manual appendix Figure 7 A threaded pipe 33 is fixedly connected to the lower end of the lifting plate 32, and a fixing block 34 is threadedly connected to the outer side of the threaded pipe 33. Positioning frames 35 are fixedly connected to both sides of the upper end of the lifting plate 32.

[0043] It should be noted that the rotation of the fixing block 34 causes the threaded tube 33 to tighten, thereby clamping and fixing the probe part of the X-ray detector through the threaded tube 33, and supporting the medical filter membrane and positioning ring 25 through the positioning frame 35, which facilitates the control of the distance between the probe part of the X-ray detector and the medical filter membrane, and in combination with the third hydraulic push rod 31 and the lifting plate 32 during the combined test, the distance is controlled.

[0044] Working principle: 1. Filter Membrane Loading and Labeling: Install the medical filter membrane to be tested using the positioning ring 25 and fix its position using the two connecting ears; affix a label to the corresponding labeling ring 24 to mark the filter membrane's specifications and material information. Remove the fixing plate 18 and alternately place the positioning ring 25 and labeling ring 24 inside the receiving box 15 in the order of "positioning ring 25 - labeling ring 24 - positioning ring 25 - labeling ring 24...". After loading, reinstall the fixing plate 18 and support plate 20. The elasticity of the support spring 21 and telescopic rod 19 ensures that the filter membrane and positioning ring 25 are always in contact with the upper inner side of the receiving box 15, facilitating subsequent pushing. Install the loaded receiving box 15 into the designated position of the device through the sliding connection between the buckle body 17 and the buckle seat 5. During installation, the moving frame 14 and the first docking rod 23 automatically dock and fix through sliding friction.

[0045] 2. Test Environment Construction and Gap Control: X-ray Source Installation and Selection: The X-ray diffractometer and X-ray machine emission structures are respectively mounted on two mounting brackets 11. By rotating the fixing screw 8 and the rotating block 9, the height of the rotating bracket 10 can be adjusted, thereby selecting different X-ray sources to simulate diverse test environments. Test Position Fixing and Isolation: The second hydraulic push rod 27 drives the detection bracket 26 to move slightly, precisely aligning or misaligning it with the exit square hole of the receiving box 15. When aligned, the filter membrane enters the test position; when misaligned, the test position can be closed to prevent interference from other filter membranes and ensure a constant test gap between the X-ray source and the filter membrane. Probe Positioning: The third hydraulic push rod 31 drives the lifting plate 32 and the X-ray detector probe mounted on it to rise and fall. By rotating the fixing block 34, the clamping tightness of the threaded tube 33 can be adjusted, thereby precisely controlling the distance between the probe and the filter membrane to meet the requirements of different test standards.

[0046] 3. Filter Membrane Pushing and Positioning: The pushing assembly is activated, and the first hydraulic push rod 13 drives the moving frame 14 to move along the support frame 12, causing the first docking rod 23 and the first push plate 22 to advance. The first push plate 22 pushes the uppermost positioning ring 25 and the medical filter membrane it carries out through the square hole on the side of the receiving box 15 and into the positioning structure of the testing frame 26. The upper end of the receiving box 15 has a hole with the same outer diameter as the marking ring 24, allowing the marking ring 24 to enter the limiting tube 6, facilitating the operator's identification of the filter membrane specification currently being tested.

[0047] 4. Test execution and data acquisition: Select an X-ray source to emit X-rays. The X-rays penetrate the medical filter membrane located inside the detection frame 26 and precisely positioned by the second limiting groove 28. The X-ray detector probe behind the filter membrane receives the X-ray signal after penetration. The system evaluates the filtration effect of the medical filter membrane by analyzing parameters such as the X-ray intensity before and after penetration.

[0048] 5. Testing and Filter Membrane Control: Continuous testing. If continuous or combined testing of the same filter membrane is required, it can be kept in the detection position. The positioning ring 25 and the filter membrane can be lowered by the lifting component. The new positioning ring 25 and filter membrane can be pushed into the positioning structure by the pushing component, thereby performing combined testing.

[0049] 6. Discharge and Collection: After a single test is completed, the second hydraulic push rod 27 drives the test frame 26 to move, aligning the lower port with the collection path. Then, the moving frame 14 and the second push plate 29 push out the used filter membrane and positioning ring 25; the discharged filter membrane and positioning ring 25 fall into the collection box 4 supported by the receiving frame 3 inside the support box 1, facilitating subsequent recycling, marking, or retesting.

[0050] 7. Device Reset and Preparation for the Next Test: The pushing component drives the first push plate 22 to reset. The next set of filter membranes in the receiving box 15 rises to the push position under the action of the support spring 21. The moving parts such as the test frame 26 and the lifting plate 32 reset to their initial positions. The operator can observe the next identification ring 24 exposed at the top of the receiving box 15 to confirm the specifications of the filter membrane to be tested, thereby quickly carrying out continuous batch testing.
