Description

Technical Field

[0001] This utility model relates to a multifunctional X-ray imaging stand, belonging to the technical field of X-ray imaging stand. Background Technology

[0002] An X-ray machine is an important imaging device that uses X-rays. In the medical field, it is a key tool for diagnosing various diseases. It can clearly capture images of human bones, joints, chest, abdomen, and other parts, assisting doctors in judging fractures, lesions, inflammation, tumors, etc., and is also used to guide interventional radiology procedures. It mainly consists of the following parts: The X-ray tube is the core, including the cathode (the filament heats up to generate electrons, which are focused and emitted by the focusing cup) and the anode (electrons strike the target surface to generate X-rays). The high-voltage generator is responsible for boosting and rectifying the mains power into a high DC voltage to power the X-ray tube. The control panel allows setting and adjusting parameters such as tube current, tube voltage, and exposure time, and displays the operating status. The cooling system (air cooling or water cooling) is used to cool the X-ray tube, which generates heat during operation.

[0003] When using X-ray machines, some areas not being examined may be exposed to radiation, which poses certain health risks. For example, during medical examinations, unprotected areas of vital organs such as the gonads and the lens of the eye may be exposed to scattered radiation.

[0004] To avoid this, during medical examinations, patients are equipped with lead aprons, lead neck protectors, and lead caps to cover non-examination areas as much as possible, including vital organs and large areas of skin. However, lead aprons and other protective gear are very heavy and inconvenient to wear, leading to low X-ray imaging efficiency. Furthermore, people vary in height and weight, especially adults and children, with significant size differences, requiring multiple sets of radiation-proof lead aprons, increasing cost and storage space. Therefore, designing a multifunctional X-ray imaging stand that can quickly expose the areas to be imaged while concealing other areas can significantly improve imaging efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a multifunctional X-ray imaging stand, which solves the problem of low X-ray imaging efficiency caused by relying on wearing protective lead clothing to prevent non-examination areas from being irradiated.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A multifunctional X-ray imaging gantry includes a lifting support frame, a film cassette fixed on the lifting support frame, and an X-ray protective frame placed between the film cassette and the X-ray emitting end.

[0008] The X-ray shielding frame includes a base, a column, and a rotatable shielding plate assembly;

[0009] Two columns are fixed in parallel on the base. A row of rotatable shielding sheet assemblies is installed on each column from bottom to top. When the rotatable shielding sheet assemblies on both sides are completely closed inward, the patient is completely shielded.

[0010] The rotatable shielding assembly includes a sleeve, a bearing, a protective lead plate, a positioning sleeve, and an elastic convex ball. The sleeve is rotatably mounted on a column via the bearing. The protective lead plate is fixed to one side of the outer wall of the sleeve, and a positioning sleeve is fixed to the inner wall of the sleeve. The inner wall of the positioning sleeve has multiple positioning recesses. A retractable elastic convex ball that mates with the positioning recesses is provided on the column. When the sleeve rotates, the retractable elastic convex ball switches positions between different positioning recesses. At this time, the part of the protective lead plate that does not shield the human body forms an inspection window that allows X-rays to pass through.

[0011] Preferably, the elastic convex ball includes a horizontal tube embedded in the column, a spring is placed inside the horizontal tube, and steel balls are placed inside the horizontal tube at both ends of the spring. The opening of the horizontal tube gradually narrows, and the inner diameter of the opening of the horizontal tube is smaller than the diameter of the steel ball. The steel ball is compressed by the spring and protrudes from the surface of the column.

[0012] Preferably, the sleeve is provided with an observation hole, and the column is provided with a scale at a position corresponding to the observation hole.

[0013] Preferably, the positioning sleeve is a tube made of POM plastic, with threaded holes on its outer circumference. The positioning sleeve is inserted into the tube and fixed by screws screwed into the outer wall of the tube.

[0014] Preferably, the protective lead plate has a mating groove on its edge, and adjacent protective lead plates are mated together by the mating groove to cover the gaps.

[0015] The beneficial effects of this invention are as follows: By adding an X-ray protective frame between the human body and the X-ray emitting end, the purpose of protection is achieved; the rotatable shielding plate assembly is similar to many protective doors pieced together, each of which can be opened or closed independently. When the patient is being examined, the examination area can be exposed to the X-ray irradiation range as needed, while other parts are shielded by protective lead plates, making the X-ray examination healthier; it can be used for both standing and sitting posture examinations, and can replace lead caps, lead neck braces, lead aprons, and lead pants, demonstrating its multi-functionality; the rotating mechanism of the rotatable shielding plate assembly adopts a stop type, which can control the opening and closing angle, so as to further control the patient's lateral exposure and further precisely control the irradiation range of the X-ray examination.

[0024] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] like Figure 1 , Figure 2 As shown, this multifunctional X-ray imaging gantry includes a lifting support frame 1, a film cassette 2 fixed on the lifting support frame 1, and an X-ray protective frame 3 placed between the film cassette 2 and the X-ray emitting end.

[0026] During X-ray imaging, the lifting support frame 1 can drive the film cassette 2 to move up and down to adapt to different imaging positions. Common imaging postures include standing and sitting postures. The lifting support frame 1 can adjust the height of the film cassette 2 according to changes in the imaging posture and the imaging position to achieve optimal imaging results.

[0027] During X-ray imaging, to prevent radiation to areas not being examined, an X-ray shield 3 is added in front of the lifting support frame 1 and the film cassette 2. The human body is positioned between the film cassette 2 and the X-ray shield 3. The X-ray shield 3 serves to block X-rays.

[0028] The X-ray protective frame 3 includes a base 31, a column 32, and a rotatable shielding plate assembly 33. The base 31 is made of steel, and the column 32 is made of smooth stainless steel.

[0029] Two columns 32 are fixed in parallel on the base 31. The columns 32 are fixed by bolts that pass through from the bottom of the base 31. A row of rotatable shielding sheet assemblies 33 is installed on each column 32 from bottom to top. When the rotatable shielding sheet assemblies 33 on both sides are completely closed inward, they completely shield the patient.

[0030] To more precisely control the height of the inspection window 5, the height of each set of rotatable shielding plate assemblies 33 (i.e., the distance from the bottom edge to the top edge of the rotatable shielding plate assembly 33 in the vertical direction) should be as small as possible. For example, the height of the rotatable shielding plate assembly 33 can be set to 3cm, so that the height of the inspection window 5 can be adjusted in 3cm increments.

[0031] like Figures 3-5 As shown, the rotatable shielding plate assembly 33 includes a sleeve 331, a bearing 332, a protective lead plate 333, a positioning sleeve 334, and an elastic convex ball 4. The sleeve 331 is rotatably mounted on the column 32 via the bearing 332. The protective lead plate 333 is fixed to one side of the outer wall of the sleeve 331. The positioning sleeve 334 is fixed to the inner wall of the sleeve 331. The inner wall of the positioning sleeve 334 has multiple positioning recesses 337. The column 32 is provided with a retractable elastic convex ball 4 that cooperates with the positioning recesses 337. When the sleeve 331 rotates, the retractable elastic convex ball 4 switches positions between different positioning recesses 337. At this time, the part of the protective lead plate 333 that does not shield the human body forms an inspection window 5 that allows X-rays to pass through.

[0032] The positioning sleeve 334 is a tube made of POM plastic. The outer circumference of the positioning sleeve 334 is provided with a threaded hole 336. The positioning sleeve 334 is inserted into the sleeve 331 and fixed by a screw screwed into the outer wall of the sleeve 331. POM plastic has excellent wear resistance and lubricity, which facilitates the rotation of the elastic convex ball 4 on the inner wall of the positioning sleeve 334.

[0033] In order to more precisely control the width of the inspection window 5, the number of positioning recesses 337 opened on the inner wall of the positioning sleeve 334 is as large as possible, so that more angles can be adjusted and the horizontal shielding range can be controlled more precisely. For example, there are two adjustment settings: (1) The positions are evenly divided according to the rotation angle. In this case, the projection width of the protective lead plate 333 on the front of the human body is uneven. A positioning recess 337 can be set every 15°. In this way, 90° from fully closed to fully open will be divided into 6 parts and 7 endpoints. Each endpoint is a position. The rotatable shielding plate assembly 33 can adjust the width of the inspection window 5 through 7 positions. The width of each position is uneven. (2) The positions are evenly divided according to the projection width. The positions are set according to the projection width of the protective lead plate 333 on the front of the human body. The width of each position is the same. The angle distribution of the positioning recesses 337 is set in this way.

[0034] By adjusting the height and width of the inspection window 5 that allows X-rays to pass through in the above manner, the radiation range can be precisely controlled, thus protecting non-inspection areas.

[0035] like Figures 3-5 As shown, to ensure clear and stable feedback during gear adjustment, a flexible convex ball 4 is used for gear differentiation. The flexible convex ball 4 includes a horizontal tube 401 embedded in the column 32, a spring 402 placed inside the horizontal tube 401, and steel balls 403 placed inside the horizontal tube 401 at both ends of the spring 402. The opening of the horizontal tube 401 gradually narrows, and the inner diameter of the opening of the horizontal tube 401 is smaller than the diameter of the steel ball 403. The steel ball 403 is pressed by the spring 402 and protrudes from the surface of the column 32.

[0036] When medical staff rotate the protective lead plate 333 as needed, the steel ball 403 is squeezed and compressed into the horizontal tube 401; until the steel ball 403 rotates to the positioning recess 337 of the next position, the steel ball 403 rebounds, the rotation resistance changes significantly, and a slight clicking sound can be heard.

[0037] like Figure 3 , Figure 4 As shown, in order to make the gear adjustment more visible, the sleeve 331 is provided with an observation hole 335, and the column 32 is provided with a scale at the position corresponding to the observation hole 335.

[0038] The scale can be represented by the distance from the vertical edge of the projection of the protective lead plate 333 to the vertical center line. The sum of the two scales of the two symmetrical protective lead plates 333 is the width of the inspection window 5 formed by this set of protective lead plates 333.

[0039] During X-ray imaging, it can be used for both standing and sitting posture checks. It can replace lead caps, lead neck braces, lead aprons, and lead trousers, demonstrating its multi-functionality: it has head, neck, chest, genital, and leg covering functions.

[0040] like Figure 6 , Figure 7 As shown, the protective lead plate 333 has a mating groove 338 on its edge, and adjacent protective lead plates 333 are mated together by the mating groove 338 to cover gaps. Not only are the edges of the protective lead plates 333 on the left and right sides provided with mating grooves 338, but the edges of the vertically adjacent protective lead plates 333 are also provided with mating grooves 338. Both horizontal and vertical gaps are completely covered.

[0041] When the protective lead plates 333 on both sides are fully closed inward, the interlocking grooves 338 can block the seam to prevent X-rays from passing through the gap and causing unnecessary radiation damage, thus better protecting the human body.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
