Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a portable X-ray detection box. Background Art

[0002] The portable X-ray detection box, also known as a portable X-ray machine, is a small (miniature) X-ray machine that uses the principle of X-rays to achieve the purpose of fluoroscopy. The portable X-ray machine mainly consists of an X-ray tube, a power supply, and a control circuit. The X-ray tube is composed of a cathode filament (Cathod), an anode target (Anode), and a vacuum glass tube. A high-voltage electric field is provided to make the active electrons on the filament accelerate towards the cathode, forming a high-speed electron flow. The high-speed electron flow penetrates the object and, after being processed by the portable X-ray machine, generates a fluoroscopic image.

[0003] In the prior art, the Chinese patent document with the publication number CN106725546B proposed a portable digital X-ray machine, including: an X-ray head for generating X-rays and a frame for supporting the X-ray head. The frame includes a mounting part and at least two support parts. A combined joint is installed on the mounting part. The support part includes a telescopic frame, and the telescopic frame is rotatably connected to the mounting part. Although the utility model can meet the radiography requirements of different positions during clinical radiography by relatively rotating the support part and the mounting part, this technology is the same as the traditional method in two aspects: First, in the traditional X-ray detection box, when in use, the output mirror at the output port is exposed outside. During irradiation, since manual operation by the operator is required, the risk of the operator contacting X-rays is relatively high, which may cause potential health risk problems. Second, in the traditional X-ray detection box, during irradiation, the whole person is irradiated. When local detection of a person's arm is required, due to unstable hand-held irradiation and inaccurate detection, there are blind spots or errors during the detection process, which affects the accuracy of the detection result.

[0032] As Figures 1 to 7As shown in the figure, an embodiment of the present utility model provides a portable X-ray detection box, which includes a main chassis 1. On one side of the main chassis 1, an output mirror 2 for outputting X-rays is installed. On one side of the main chassis 1, a radiation protection component is provided. The radiation protection component includes a cross-shaped telescopic frame 23, a second fixed rod 42, a large trapezoidal plate 24, a small trapezoidal plate 25, and a guide rod 43. The second fixed rod 42 is fixed on the main chassis 1, and a forward screw rod 21 and a reverse screw rod 22 are rotatably connected to one side of the second fixed rod 42. One end of the forward screw rod 21 is fixedly connected to a driven wheel 30. On the side of the driven wheel 30 away from the forward screw rod 21, the reverse screw rod 22 is fixedly connected. The outer parts of the forward screw rod 21 and the reverse screw rod 22 are slidably connected with the cross-shaped telescopic frame 23 through a threaded block. One end of the cross-shaped telescopic frame 23 away from the forward screw rod 21 and the reverse screw rod 22 is slidably connected with the guide rod 43 through a shaft block. On the same side as the forward screw rod 21 of the second fixed rod 42, a large trapezoidal plate 24 is rotatably connected through a hinge. The two inclined sides of the large trapezoidal plate 24 are also rotatably connected with a small trapezoidal plate 25 through a hinge. On one side of the radiation protection component, an expansion component for expanding the radiation protection range is provided. The expansion component includes a first fixed rod 31, a cross-shaped crossbar 32, and a radiation protection cloth 33. The first fixed rod 31 is fixedly connected to one side of the main chassis 1. On the side of the first fixed rod 31 opposite to the second fixed rod 42, a plurality of cross-shaped crossbars 32 are rotatably connected through a shaft. A radiation protection cloth 33 is fixedly connected at the gaps of the plurality of cross-shaped crossbars 32. And one end of the plurality of cross-shaped crossbars 32 away from the first fixed rod 31 is rotatably connected to one side of the second fixed rod 42 through a shaft. At the bottom of the main chassis 1, a folding component for precise irradiation is also provided. The folding component includes a first folding plate 3, a second folding plate 13, and a third folding plate 20. The first folding plate 3 is rotatably connected to the bottom of the main chassis 1 through a shaft. On both sides of the first folding plate 3, first arc-shaped frames 9 are rotatably connected through a shaft. One end of the first arc-shaped frame 9 away from the first folding plate 3 is slidably connected to one side of the second folding plate 13. On both sides of one end of the second folding plate 13, second arc-shaped frames 15 are threadedly connected. One end of the second arc-shaped frame 15 away from the second folding plate 13 is rotatably connected to one side of the third folding plate 20 through a shaft. On the side of the main chassis 1 where the second fixed rod 42 is located, a fixing plate 26 is fixedly connected. On one side of the fixing plate 26, a worm 27 is rotatably connected. One end of the worm 27 is fixedly connected to a turning handle 28. On one side of the worm 27, a worm gear 29 is meshed. The worm gear 29 is rotatably connected to one side of the fixing plate 26 through a shaft. On the other side of the worm gear 29, the driven wheel 30 is meshed.

[0033] Through the provided radiation protection component, the radiation damage of X-rays to the operator can be prevented, thus ensuring the safety of the operator. During use, first rotate the worm 27 to prompt the worm gear 29 to drive the worm gear 29 to rotate. At this time, the forward screw 21 and the reverse screw 22 will rotate, and at the same time, the cross telescopic frame 23 will extend. At this time, the guide rod 43 will move away from the second fixed rod 42. At the same time, through the stretching of the guide rod 43, multiple large trapezoidal plates 24 and multiple small trapezoidal plates 25 will unfold, thereby wrapping the front end area of the output mirror 2. In this way, a box body is formed to minimize the risk of the operator contacting X-rays. At the same time, these radiation protection components are made of lead borated polyethylene plates, which can effectively block X-ray radiation, thereby further protecting the safety of the operator. At the same time, through the design of the worm 27, worm gear 29, and turning handle 28 structures, the unfolding and folding of the radiation protection component and the expansion component are made more convenient and fast.

[0034] As Figures 1 to 6 shown, there are multiple large trapezoidal plates 24. The multiple large trapezoidal plates 24 are connected to each other through hinges. And both inclined sides of the multiple large trapezoidal plates 24 are rotatably connected to small trapezoidal plates 25 through hinges. And the tops of the multiple small trapezoidal plates 25 are connected to each other through hinges. One side of the large trapezoidal plate 24 that is farthest from the second fixed rod 42 among the multiple large trapezoidal plates 24 is slidably connected to the outside of the guide rod 43 through a slider. The large trapezoidal plates 24 and the small trapezoidal plates 25 are made of lead borated polyethylene plates. There are two radiation protection components, and the two radiation protection components are symmetrically wrapped around both sides of the output mirror 2. An expansion plate 44 is slidably connected inside the small trapezoidal plate 25. Both sides of the expansion plate 44 are slidably connected inside the small trapezoidal plates 25 of the two radiation protection components. The expansion plate 44 is made of lead borated polyethylene plates. The expansion plate 44 and the two radiation protection components are combined into a box body to wrap around the outside of the output mirror 2.

[0035] By setting the large trapezoidal plates 24 and the small trapezoidal plates 25 to be made of lead borated polyethylene plates, X-ray radiation can be effectively blocked, thus protecting the safety of the operator. At the same time, wrapping the two radiation protection components symmetrically around both sides of the output mirror 2 can minimize the risk of the operator contacting X-rays. At the same time, by setting the expansion plate 44, when the radiation protection component expands, the expansion plate 44 will unfold, thereby covering the gap, thus avoiding the problem of X-rays leaking out from the expansion.

[0036] As Figures 1 to 7As shown, the specification dimensions of the expansion component are adapted to those of the radiation protection component. The material of the radiation protection cloth 33 is a metal fiber blended fabric material. One side of the top of the second fixing rod 42 is fixedly connected to a placement box 36. Inside the placement box 36, a spiral spring 37 is installed. One end of the spiral spring 37 is connected to one side of the central column inside the placement box 36. The end of the spiral spring 37 far from the central column is fixedly connected to a pull rope 38. The top of the main chassis 1 is rotatably connected to a rope winding roller 35. The end of the pull rope 38 far from the central column is rotatably connected to the outside of the rope winding roller 35. The top of the rope winding roller 35 is fixedly connected to a runner 39 through a shaft. The top of the runner 39 is fixedly connected to a crank 40. Inside the crank 40, a positioning rod 41 is sleeved. On the top of the main chassis 1, a plurality of fixing holes 34 are also opened. The specification dimensions of the plurality of fixing holes 34 are adapted to those of the positioning rod 41, and the positions of the plurality of fixing holes 34 are circularly arranged at the bottom of the runner 39.

[0037] By setting the expansion component, the size of the radiation protection component can be extended according to the size of the irradiated object, thereby further expanding the radiation protection range and improving the safety during detection. During use, the positioning rod 41 is pulled out from the inside of the fixing hole 34. At this time, due to the action of the spiral spring 37, it is prompted to stretch and contract into the inside of the placement box 36, and at the same time, the second fixing rod 42 is prompted to pull the cross-shaped rod 32 to unfold, thereby prompting the radiation protection component to expand. At the same time, the radiation protection cloth 33 will unfold, so as to ensure covering a larger area, making the X-ray detection work more comprehensive and effective. At the same time, by setting the material of the radiation protection cloth 33 to be a metal fiber blended fabric material, it can play a role in blocking the diffusion of radiation, and thus maximally protect the operator from radiation.

Semi-circular plates 4 are fixedly connected to both sides of one end of the first folding plate 3. Semi-circular holes are provided inside the semi-circular plates 4.

A threaded groove is provided on one side of one end of the second folding plate 13. A screw rod is fixedly connected to one side of the fourth knob 14.

Card slots are respectively provided on one side of one end of the first folding plate 3 and the second folding plate 13. The specifications and dimensions of the card slots are adapted to the specifications and dimensions of the first plug-in plate 7 and the second plug-in plate 18. A second knob 8 and a sixth knob 17 are respectively rotatably connected to one side of one end of the second folding plate 13 and the third folding plate 20. Screw rods are fixedly connected to one side of the second knob 8 and the sixth knob 17.

A first knob 6 and a fifth knob 16 are respectively rotatably connected to one side of one end of the first folding plate 3 and the second folding plate 13. Bolts are fixedly connected to one side of the first knob 6 and the fifth knob 16. One side of the bolts away from the first knob 6 and the fifth knob 16 respectively pass through the side walls of the first folding plate 3 and the second folding plate 13 and are threadedly connected to one side of the other end of the first plug-in plate 7 and the second plug-in plate 18.

[0039] Through the set folding component, precise irradiation of the target can be achieved, ensuring that X-rays can be accurately projected onto the area to be detected. When in use, first rotate the first folding plate 3 to make the sliding bolt 5 slide to one end of the semi-circular plate 4. At this time, the first folding plate 3 will be perpendicular to the bottom of the main chassis 1. Then rotate the second folding plate 13 to make the sliding plate 11 slide inside the sliding groove 10, so that the second folding plate 13 is perpendicular to the first folding plate 3. Then rotate the third knob 12 to insert the bolt into the sliding groove 10, thereby fixing the position of the first arc-shaped frame 9. At this time, insert the first plug-in plate 7 into one side of the bottom of the first folding plate 3, and at the same time rotate the first knob 6 and the second knob 8 to insert the screw rod into one side of the first plug-in plate 7 to fix the position of the first plug-in plate 7, so that the second folding plate 13 is vertically fixed to the bottom of the first folding plate 3. Then rotate and unfold the third folding plate 20 to make the second arc-shaped frame 15 move on one side of the fourth knob 14. When the third folding plate 20 is perpendicular to one side of the second folding plate 13, rotate the fourth knob 14 to rotate the screw rod into one side of the second folding plate 13 to fix the position of the second arc-shaped frame 15. Then insert one end of the second plug-in plate 18 into one side of the second folding plate 13. At this time, rotate the fifth knob 16 and the sixth knob 17 to insert the screw rod into one side of the second plug-in plate 18, thereby fixing the position of the second plug-in plate 18. At this time, the third folding plate 20 will be perpendicular to the bottom of the second folding plate 13, and at the same time the position of the output mirror 2 will correspond to the position of the sponge pad 19. At this time, the patient places the arm on the sponge pad 19, thus realizing the function of local detection of the human arm, further improving the accuracy and effectiveness of X-ray detection. At the same time, by using knobs for fixation, the folding plates can be folded with each other, which is convenient for carrying. At the same time, the design of the folding plates and the plug-in plates provides better fixation and stability, enhancing the safety and stability of the equipment.

[0040] For the technical solution provided by the present utility model, first, by setting the radiation protection component, the radiation damage of X-rays to the operator can be prevented, thus ensuring the safety of the operator.

[0041] Then, by setting the expansion component, the size of the radiation protection component can be extended according to the size of the irradiated object, thereby further expanding the radiation protection range and improving the safety during detection. When in use, the positioning rod 41 is pulled out from the inside of the fixing hole 34. At this time, under the action of the spiral spring 37, it is stretched and contracted into the inside of the placement box 36, and at the same time, the second fixing rod 42 pulls the cross-shaped rod 32 to expand, thereby promoting the expansion of the radiation protection component. At the same time, the radiation protection cloth 33 will be unfolded, so as to ensure covering a larger area and making the X-ray detection work more comprehensive and effective;

[0042] Finally, by setting the folding component, precise irradiation of the target can be achieved, and it can ensure that the X-ray is accurately projected onto the area to be detected. When in use, the first folding plate 3, the second folding plate 13, and the third folding plate 20 are unfolded, so as to make the position of the output mirror 2 correspond to the position of the sponge pad 19. At this time, one side of the third folding plate 20 is placed on the table, and then the patient places the arm on the sponge pad 19, so as to achieve the function of locally detecting the human arm, and further improve the accuracy and effectiveness of X-ray detection.
