Description

Technical Field

[0001] This utility model relates to the field of X-ray imaging technology, and in particular to a radiation protection device specifically for chest X-ray imaging. Background Technology

[0002] Currently, when hospitals use upright chest X-ray stands to take chest X-rays for patients, in order to reduce the radiation hazards of X-rays and protect the patient's health, most hospitals only use lead aprons to protect the gonads in the lower abdomen, while a few hospitals use two-piece protective devices to protect the lower abdomen and head from radiation.

[0003] Common lead aprons offer protection in several ways: they cover too little area, take too long to put on, and are too heavy for the weak. Two-piece protective devices are typically simple frames that cannot automatically adjust their position. Because patients vary in height and build, manual adjustments are required each time to ensure effective protection without affecting the diagnostic area. This process is time-consuming, inefficient, and provides poor protection. While two-piece protective devices can be electrically adjusted to align and cover the protective area, these devices are complex, require a large footprint, and incur high purchase and maintenance costs.

[0028] like Figure 1 As shown in the figure, a preferred embodiment of the radiation protection device for chest X-ray imaging includes a vertically arranged column 1, on which a connecting device 2 is mounted. The connecting device 2 is movably connected to the column 1 and is also connected to the chest X-ray frame of the chest X-ray imaging device, and can move with the chest X-ray frame. At least two fixing rods 3 are connected to the other end of the connecting device 2. The fixing rods 3 are horizontally arranged and rotatably connected to the connecting device 2. Lead curtains 4 are connected to the bottom of the fixing rods 3. The lead curtains 4 have good radiation protection effect. The lead curtains 4 are 60cm long, and the interval between the two lead curtains 4 is 43cm. The upper lead curtain 4 is 40cm wide, and the lower lead curtain 4 is 50cm wide.

[0029] The column 1 is vertically positioned near the X-ray imaging device. A connecting device 2 is movably mounted on the column 1. Two fixed rods 3 are connected to the other end of the connecting device 2. A lead curtain 4 for blocking radiation is positioned below the two fixed rods 3. There is a gap between the lead curtains 4, through which the X-ray imaging device takes X-ray images of the subject's chest. The connecting device 2 is movable on the column 1, allowing the lead curtains 4 to be adjusted vertically along with the chest X-ray frame, so that it can be adapted to the chest position of the subject at different heights. While ensuring the protective effect, the imaging effect of chest X-ray is also guaranteed. This application has a simple structure and also reduces adjustment costs.

[0030] In some embodiments of this utility model, a slide rail 11 is vertically arranged on the column 1, and the slide rail 11 is recessed inside the column 1. The connecting device 2 includes a vertically arranged slider 21, which is slidably connected to the slide rail 11 and is also connected to the chest X-ray frame. When the chest X-ray frame drives the slider 21 to slide within the slide rail 11, it can drive the fixing rod 3 and the lead curtain 4 to slide, thus realizing the real-time adjustable position of the lead curtain 4. Furthermore, a limit device is provided inside the slide rail 11 so that the slider 21 can be fixed inside the slide rail 11 after the lead curtain 4 reaches the appropriate position, ensuring the fixed position of the lead curtain 4.

[0031] like Figure 2 As shown, in some embodiments of this utility model, a spring gravity balancer 5 is provided on the column 1. The spring gravity balancer 5 includes an elastic element 51 fixed to the top of the column 1 and a connecting part 52. The two ends of the connecting part 52 are respectively connected to the elastic element 51 and the connecting device 2. The weight of the connecting device 2 and the lead curtain 4 are both borne by the spring gravity balancer 5. The spring gravity balancer 5 is fixed to the column 1 through the elastic element 51 at the top, and provides an upward force to the slider 21 in real time through the connecting part 52 to prevent the slider 21 from falling too fast. It also enables the connecting device to achieve gravity balance as a whole, reducing the pressure that the chest X-ray frame needs to bear.

[0032] In some embodiments of this utility model, the connecting device 2 further includes a first connecting rod 22 rotatably connected to the slider 21. Two first connecting rods 22 are provided, and the end of each first connecting rod 22 is connected to a vertically arranged second connecting rod 23. The fixing rod 3 is connected to the second connecting rod 23. The first connecting rod 22 extends horizontally in the horizontal direction, and its end is connected to the fixing rod 3 through the second connecting rod 23.

[0033] In some embodiments of this utility model, the first connecting rod 22 includes a fixed section 221 and a telescopic section 222. The fixed section 221 is connected to the slider 21. A receiving groove 223 is provided inside the fixed section 221. The depth of the receiving groove 223 is less than the length of the telescopic section 222. The size of the telescopic section 222 matches the size of the receiving groove 223 so that one end of the telescopic section 222 can be telescopically set inside the receiving groove 223. The end of the telescopic section 222 is connected to the second connecting rod 23. By adjusting the position of the telescopic section 222, the position between the fixed rod 3 and the lead curtain 4 and the X-ray imaging device can be adjusted to meet the imaging needs of subjects with different chest wall thicknesses, so that the lead curtain 4 can always fit in close contact with the subject, ensuring the protective effect for subjects with different degrees of obesity.

[0034] In some embodiments of this utility model, a sliding damper 224 is provided between the receiving groove 223 and the telescopic section 222 so that the telescopic section 222 can stop at any position. The sliding damper 224 allows the telescopic section 222 to be adjusted when force is applied, but can stop at any position when no force is applied, which simplifies the adjustment method, reduces the adjustment cost, and eliminates the need for an additional limiting mechanism.

[0035] In some embodiments of this utility model, a handle 231 is provided on the second connecting rod 23 to pull the telescopic section 222. Pulling the handle 231 can adjust the position of the telescopic section 222, and releasing the handle 231 and sliding the damper 224 can fix the telescopic section 222. Preferably, the handle 231 is located in the middle of the second connecting rod 23, so that it applies force evenly to the two telescopic sections 222, and the pushing and pulling process is relatively smooth.

[0036] like Figure 3 As shown, in some embodiments of this utility model, a first locking groove 232 is provided on the second connecting rod 23. The first locking groove 232 is horizontally opened. A first protruding end 31 that cooperates with the first locking groove 232 is provided at one end of the fixing rod 3 near the second connecting rod 23. The first protruding end 31 is also horizontally set. Since the fixing rod 3 is rotatably connected to the second connecting rod 23 in the horizontal direction, when the lead curtain 4 needs to be closed, the first protruding end 31 is inserted into the first locking groove 232 to fix the lead curtain 4. When the lead curtain 4 needs to be opened, the first protruding end 31 can be pulled out from the first locking groove 232 by force.

[0037] In some embodiments of this utility model, the second connecting rod 23 is vertically provided with an extension 24, and a second locking groove 241 is provided in the extension 24. The second locking groove 241 is horizontally provided. The fixing rod is provided with a second protruding end 32 that matches the size of the second locking groove 241. The second protruding end 32 is back-to-back with the first protruding end. Therefore, when the lead curtain 4 needs to be opened, the second protruding end 32 is inserted into the second locking groove 241 to fix the lead curtain 4. When the lead curtain 4 needs to be closed, the second protruding end 32 is pulled out from the second locking groove 241 by force, and then the first protruding end 31 is inserted into the first locking groove 232.

[0038] The first locking groove 232, the second locking groove 241, the first protruding end 31, and the second protruding end 32 are provided so that the fixing rod 3 and the lead curtain 4 connected to the fixing rod 3 can be opened and closed at 90°, which facilitates the entry and exit of the person to be tested and also ensures that the lead curtain is always in close contact with the person to be tested during X-ray imaging, thus guaranteeing the protective effect of this application.

[0039] Preferably, two spring pieces 233 are provided at the entrance of the first locking groove 232 and the second locking groove 241, so that the first protruding end 31 is fixed firmly in the first locking groove 232, and the first protruding end 31 can be easily pulled out when the fixing rod 3 is exerted in the direction of the outlet.

[0040] In some embodiments of this utility model, a base 6 is provided at the bottom of the column 1, and the column 1 is rotatably connected to the base 6 to make the column 1 fixed and stable.

[0041] The working process of this utility model is as follows: The column 1 is vertically set close to the X-ray imaging device. A connecting device 2 is movably set on the column 1. Two fixing rods 3 are connected to the other end of the connecting device 2. A lead curtain 4 for blocking radiation is set below the two fixing rods 3. There is a gap between the lead curtains 4. The X-ray imaging device takes X-ray pictures of the chest of the subject through the gap. The connecting device 2 is movably set on the column 1 so that the lead curtain 4 can be adjusted vertically with the chest X-ray frame so that it can be adapted to the chest position of the subject at different heights.

[0042] In summary, this utility model provides a radiation protection device specifically for chest X-ray imaging, which can be adapted to the chest position of subjects at different heights. While ensuring the protection effect, it also ensures the imaging effect of chest X-ray imaging. This application has a simple structure and also reduces adjustment costs.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
