Description

Technical Field

[0001] The present application relates to the technical field of medical protection equipment, and in particular to a medical radiation protection device. Background Art

[0002] Medical rays, especially X-rays, play a vital role in the field of interventional medicine. They can penetrate human tissues, reveal the internal structure of bones, organs and tissues, and provide doctors with valuable diagnostic information. However, just as there are two sides to a coin, the use of X-rays is also accompanied by potential risks. Radiation can cause damage to human cells and tissues. Therefore, when using medical rays, strict safety measures and protective measures must be taken to protect the parts of the patient that do not need to be irradiated by X-rays.

[0003] At present, there are many medical radiation protection devices on the market, among which the most common one is to use lead plates for radiation shielding. These devices effectively reduce the direct exposure of radiation to the human body by means of physical blocking. For example, the existing publication number CN211985471U is a radiology medical radiation protection device: in the above scheme, it includes a protection column shell, a main support rod, a protection frame and a radiation protection cloth, the main support rod is fixedly welded inside the protection column shell, the side surface of the main support rod is movably sleeved with two electric slide rods, the side surfaces of the two electric slide rods are fixedly welded with support rods, the other ends of the two support rods are fixedly installed with a rotating pin, one end of the two protection frames is fixedly welded to the side surface of the top of the bracket, the rotating machine is fixedly welded with a rotating rod near the side of the protection frame, the side surface of the rotating rod is fixedly connected with a connecting protection cloth, three buttons are movably connected with three button seats, the bottom end of the radiation protection cloth is fixedly connected with a support rod, the side surfaces of the two electric slide rods are fixedly connected with distribution wires, and the ends of the two rotating machines away from the protection frame are fixedly connected with auxiliary wires. The utility model is a radiology medical radiation protection device with good protection effect, easy to use, easy to disassemble and move. However, although these devices have played a protective role to a certain extent, they still have some technical problems that cannot be ignored. First, the layout of the radiation protection cloth is often ignored in the design of existing medical radiation protection devices. When the radiation protection cloth falls, it is sometimes hindered by the supporting base, resulting in the protection cloth being unable to completely cover the area that needs to be protected, especially the foot area. This design flaw may cause radiation to penetrate from areas that are not covered, thereby increasing the risk of radiation exposure to personnel. Secondly, due to the large number of internal parts and complex structure of the device, once a part is damaged, it often needs to be disassembled and replaced as a whole, which increases the difficulty and cost of maintenance.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Example:

[0022] See also Figure 1 , Figure 2 , Figure 3 A medical radiation protection device comprises a base 1 and four self-locking universal wheels 3 bolted to the bottom of the base 1 and two handles 4 welded to the outer side wall of an adjustment frame 226.

[0023] Among them, the base 1 is made of high-strength material and has excellent load-bearing capacity and stability; in addition, a counterweight block is provided inside the base 1, and its stability is further improved by increasing the weight of the base 1, so that when the support frame 213 slides to one end of the slide rail 211 along with the slider 212, the device remains stable. The counterweight block is made of high-density material, which not only ensures the weight but also does not affect the overall structure of the device.

[0024] Among them, the design of the self-locking universal wheels 3 gives the medical radiation protection device excellent mobility; with the help of these self-locking universal wheels 3, the device can be easily and quickly moved to the specified position, greatly improving the convenience of use; what is more outstanding is that the application of the self-locking function ensures that the device can be firmly locked after reaching the specified position, effectively preventing any unnecessary displacement during the radiation inspection process, thereby ensuring the accuracy and safety of the inspection process.

[0025] Among them, the design of the handle 4 plays a key role in the medical radiation protection device; it not only facilitates the user to move the entire device, making it more convenient during adjustment or transportation, but also greatly enhances the comfort and stability of holding through the rubber pad arranged inside it, thereby improving the applicability of the handle 4; it is worth mentioning that the handle 4 is closely connected to the adjustment frame 226 and can move flexibly with the movement of the adjustment frame 226. This design takes into account the needs of users of different heights. Regardless of the height of the user, they can easily find a holding position that suits them, thereby achieving precise control of the device; such a design not only reflects the meticulous care for user experience, but also demonstrates the flexibility and humanization of the device design.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A medical radiation protection device comprises a radiation protection structure 2 welded on the surface of a base 1, the radiation protection structure 2 consists of a supporting mechanism 21, an adjusting mechanism 22 and a protection mechanism 23, wherein the supporting mechanism 21 comprises a slide rail 211, a slider 212, a supporting frame 213, a connecting block I 214 and a connecting block II 215; the adjusting mechanism 22 comprises a slide groove 221, a driving motor 222, a ball screw 223, a ball nut 224, two limit blocks 225, an adjusting frame 226, an adjusting motor I 227 and an adjusting motor II 228; the protection mechanism 23 comprises two auxiliary rods 231, two winding rollers 232, two radiation protection cloths 233 and two pendant rods 234.

[0027] The design of the support mechanism 21 not only provides great convenience for the installation of the adjustment mechanism 22 and the support protection mechanism 23, but also ensures the stability and safety of the entire device structure; the slide rail 211 is firmly welded to the surface of the base 1, so that the support mechanism 21 can be firmly fixed on the base 1, providing solid support for the parts installed thereon, and bumps are designed at both ends of the slide rail 211. These bumps are not only beautiful, but also can accurately limit the moving range of the slider 212, ensuring that the sliding 212 on the slide rail 211 is smooth and safe; the slider 212 and the slide The rail 211 cooperates perfectly and can slide freely on the rail 211, easily moving the support frame 213 to any end of the surface of the base 1. This design prevents the base 1 from becoming an obstacle, ensuring that the radiation protection cloth 233 can fall smoothly on the ground to cover the patient's feet. The design of the connecting block I 214 and the connecting block II 215 is also ingenious. They are not only structurally stable, but also convenient for installing the adjustment mechanism 22. This design not only simplifies the installation steps and improves work efficiency, but also makes the entire device structure more compact and beautiful.

[0028] Among them, the slider 212, the support frame 213, the connection block I 214 and the connection block II 215 are cast as one piece and made of high-strength material; this material has excellent compression, tensile and fatigue resistance, ensuring that the connection between the various components is tight and seamless, avoiding loosening or breakage during use.

[0029] Among them, the design of the adjustment mechanism 22 realizes the precise adjustment of the height of the radiation protection cloth 233. The slide groove 221 opened on the side wall of the support frame 213 provides a smooth moving trajectory for the adjustment motor I 227, ensuring the stability and accuracy of the adjustment process; the driving motor 222, the ball screw 223 and the ball nut 224 cooperate with each other to drive the adjustment frame 226 to move up and down along the support frame 213, so as to flexibly adjust the position of the radiation protection cloth 233. This design not only optimizes the adjustment efficiency, but also makes the distance between the two radiation protection cloths 233 adjustable as needed, meeting the protection needs in different scenarios. In addition, the two limit blocks 225 are firmly connected with the connecting blocks I 214 and II 215, ensuring that the adjustment mechanism 22 can be firmly fixed on the side wall of the support frame 213, providing solid support; and the design of the adjusting motor I 227 and the adjusting motor II 228 makes the release and recovery of the radiation protection cloth 233 more convenient and efficient, greatly improving the user experience.

[0030] Among them, the protection mechanism 23 plays a vital role in the medical radiation protection device. Its main function is to accurately block the parts of the patient that do not need to be examined, thereby effectively protecting the patient's health; one end of the two auxiliary rods 231 is tightly connected to the supporting frame 213 and the connecting plate of the adjusting frame 226 by bolts, respectively, to ensure the stability of the entire protection mechanism 23; at the same time, the two winding rollers 232 are respectively connected to the output ends of the adjusting motor I 227 and the adjusting motor II 228. By driving these two motors, the winding or releasing action of the winding roller 232 can be easily controlled; when it is necessary to block a specific part of the patient, the adjusting motor I 227 and the adjusting motor II 228 are used to adjust the output ends of the adjusting motor I 227 and the adjusting motor II 228. The energy-saving motor II 228 will drive the winding roller 232 to release the radiation protection cloth 233, so that it can quickly cover the parts of the patient that do not need to be examined; conversely, when the examination is completed or the shielding area needs to be adjusted, the winding roller 232 will wind up the protection cloth 233 and store it neatly. This flexible operation not only improves the inspection efficiency, but also greatly enhances the patient's comfort; in addition, the bottom of the two radiation protection cloths 233 are specially designed with pendant rods 234, and their weight can effectively prevent the radiation protection cloth 233 from being blown away by the wind, ensuring the durability and stability of the shielding effect; this detailed design not only reflects the careful consideration of patient safety, but also demonstrates the ingenuity and practicality of the device design.

[0031] The working principle of the medical radiation protection device is as follows: when in use, the user only needs to hold the handle 4 easily and use the convenient self-locking universal wheel 3 to smoothly move the base 1 in front of the patient; then, the support frame 213 can be easily pushed to one end of the base 1 by the smooth sliding of the slider 212 on the slide rail 211; then, the corresponding winding roller 232 is driven by the adjustment motor II 228 to release the radiation protection cloth 233, so that it can accurately cover the body part above the patient's body part that needs to be examined; then, the drive motor 222 is started to drive the ball screw 223 to rotate smoothly, and the radiation protection cloth 233 is released by the adjustment motor II 228. Driven by the ball nut 224, the adjustment frame 226 slowly moves upward along the support frame 213 until it reaches below the part of the patient that needs to be examined; at this time, the corresponding winding roller 232 is driven by the adjustment motor I 227 to release the radiation protection cloth 233, so that it covers the body part below the part of the patient that needs to be examined; during the whole process, the device is easy to operate, and the radiation protection cloth 233 blocks accurately and quickly, effectively protecting the parts of the patient that do not need to be examined; in this way, when the patient is examined, the blocked part is fully protected, ensuring the safety and comfort of the examination.

[0032] It should be noted that the specific models and specifications of the drive motor 222, the drive motor 227, the adjustment motor II 228, and the radiation protection cloth 233 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and principles of the drive motor 222 , the drive motor 227 , and the regulating motor II 228 are clear to those skilled in the art and will not be described in detail herein.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
