[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-4 The invention discloses a mobile radiation protection nursing device for nuclear medicine and a method of use thereof, and is used to solve the problem that the radiation protection storage lead box is sealed by a rotating cover, and when the lead box is moved, when the lead box is subjected to bumps and vibrations, the rotating cover may be offset from the barrel mouth of the lead box, causing leakage at the barrel mouth of the lead box, which brings certain deficiencies to the radiation protection lead box for nuclear medicine.

[0029] As a further technical solution proposed by the present invention, it includes a lead box body 1 and multiple covers 1.3, and also includes: a bracket 3, which is arranged on the lead box body 1, and a linkage mechanism is arranged on the bracket 3, the linkage mechanism includes multiple connecting rods 3.3; a limiting mechanism, the limiting mechanism includes multiple bases 2, multiple slide rails 2.1, multiple sliders 2.2 and multiple limiting parts 2.3 connected in sequence, and each slider 2.2 is hinged with each connecting rod 3.3; when the linkage mechanism drives the multiple connecting rods 3.3 to be pressed down, it synchronously links each slider 2.2 to move toward the side of the cover 1.3, so as to realize the abutment and cooperation of each limiting part 2.3 with each cover 1.3. Specifically, the cover 1.3 of the lead box body 1 is opened first, and then the items are placed in the lead box body 1, and the linkage mechanism drives the connecting rod 3.3 to be pressed down so that it forces the slider 2.2 to slide on the slide rail 2.1 toward the side of the cover 1.3 and abut and cooperate with it. Figure 3As shown in the state, the stability of the cover 1.3 when sealing the lead box body 1 is improved, and the situation that the rotating cover and the barrel mouth of the lead box may be offset when the lead box is subjected to bumps and vibrations during the movement of the lead box may be weakened or even avoided, resulting in leakage at the barrel mouth of the lead box.

[0030] The specific number of the covers 1.3 in this embodiment is four, which matches the number of the article storage openings of the lead box body 1. Figure 1 Status shown.

[0031] In another embodiment provided by the present invention, the linkage mechanism further includes a rotating rod 3.1 and a receiving plate 3.2, and the rotating rod 3.1 is threadedly connected to the bracket 3. Further, as Figure 4 As shown in the state, the rotating rod 3.1 arranged on the bracket 3 descends or rises through the threaded transmission with it, and the bottom of the rotating rod 3.1 is rotatably connected with the receiving plate 3.2. During the descent of the rotating rod 3.1, its bottom will rotate on the receiving plate 3.2 and force the receiving plate 3.2 to descend synchronously. The receiving plate 3.2 is specifically a disc structure, which is hinged with each connecting rod 3.3. During the descent of the receiving plate 3.2, it will force the connecting rod 3.3 to move downward in an arc shape and press down, as shown in FIG. Figure 3 Status shown.

[0032] In another embodiment provided by the present invention, preferably, the plurality of limiting parts 2.3 are composed of an arc block and a straight rod connected to the arc block, the specific number of the plurality of limiting parts 2.3 is four, each cover 1.3 is provided with a cover handle 1.4, each cover handle 1.4 is specifically a round rod structure, the limiting parts 2.3 are adapted to the number of cover handles 1.4 on the cover 1.3, and each cover handle 1.4 is adapted to each arc block, such as Figure 3 As shown in the state, during the process of the connecting rod 3.3 being pressed down, it forces the slider 2.2 to slide on the slide rail 2.1 of the base 2. During the travel of the slider 2.2, it will eventually make the limiting portion 2.3 abut against the cover handle 1.4 on the cover 1.3, thereby limiting and fixing the cover 1.3 and improving its stability during sealing.

[0033] In another embodiment of the present invention, a plurality of barrel openings 1.2 are provided on the lead box body 1, and each of the sealing covers 1.3 cooperates with each of the barrel openings 1.2. The lead box body 1 is provided with handles 1.1, and the specific number of the handles 1.1 is two. The operator can push the lead box body 1 to move by cooperating with the handles 1.1 and the rollers on the lead box body 1. Figure 1 As shown in the state, the lead box body 1 is specifically provided with four barrel openings 1.2, and the four barrel openings 1.2 can hold four types of articles, and have multiple functions. This is the prior art and will not be described in detail.

[0034] The roller of this embodiment has a braking function, and the lead box body 1 effectively isolates radioactive substances. The surface of the lead alloy produces oxides, sulfides or other complex salt compounds during the corrosion process, which have the function of preventing oxidation, sulfidation, dissolution or volatilization, so it has good corrosion resistance in air, sulfuric acid, fresh water and sea water. Furthermore, the surface standard of the lead box body 1 is that there shall be no slag, particulate oxygen, inclusions and external pollution on the surface of the lead brick, the lead brick shall not have cold insulation, and there shall be no burrs greater than 10mm. The radiation-proof lead box can block most rays, but usually a layer of barrier with a lower atomic number is added when protecting against β rays to avoid bremsstrahlung. γ rays are produced along with α and β rays and have strong penetrability. It is a prior art and will not be described in detail.

[0035] As is known, in the field of modern medicine and science and technology, radioactive materials are widely used. In order to ensure that these dangerous chemicals do not cause damage to the human body and the environment, strict measures need to be taken during their storage and handling. Among them, radioactive storage lead boxes are widely used for the safe storage of highly toxic, explosive or evaporative materials such as radiation sources and inhibitors. However, in order to make the radioactive storage lead boxes play an effective role, the corresponding operating procedures must be strictly followed. First of all, the radioactive storage lead boxes must be inspected before use. Including whether the appearance is intact and crack-free, whether the density is uniform, and the bottom support bearing capacity, etc. need to be carefully checked, and the results should be recorded in the corresponding materials for future reference.

[0036] The basic structure and principle of a common radiation-proof lead box are that it is made of high-density lead plates, steel plates and other protective materials. Its internal structure is scientifically and reasonably designed, and can effectively shield and absorb external radiation. Lead, as a metal with high density and high atomic number, has excellent protective effects on X-rays, gamma rays, etc. When the rays pass through the lead box, their energy will be absorbed or scattered by the lead atoms, thereby greatly reducing the harm caused by the rays to personnel and equipment. Furthermore, with the continuous development of science and technology, radiation protection lead boxes have achieved significant technological innovations in materials, structures, and intelligence. The application of new composite materials enables the lead box to reduce the overall weight and cost while ensuring the protective effect; the addition of an intelligent monitoring system makes the use of the lead box more convenient and safe. In addition, with the continuous integration of interdisciplinary technologies such as nanotechnology and biotechnology, the performance of future equipment will be further improved, providing humans with more comprehensive and efficient protection methods.

[0037] Radiation protection lead boxes are used in the medical field, scientific research field and industrial field. In the medical field, during medical processes such as radiotherapy and X-ray examinations, doctors and patients may suffer certain radiation damage. It can provide a safe operating environment for medical staff and protect patients from unnecessary radiation exposure. Radiation protection lead boxes, as a technological treasure that protects human life and health, play a role in many fields. With the continuous advancement and innovation of science and technology.

[0038] In today's rapidly changing science and technology, nuclear energy and radioactive substances play a vital role in many fields such as medicine, scientific research and industry. However, while these high-energy substances bring great convenience, they also hide huge safety risks. In order to protect the health and safety of workers and the public, the importance of radiation protection equipment is self-evident. Among them, the radiation protection lead box, as an efficient and reliable protective equipment, is becoming an important barrier to protect humans from the threat of radiation. The present invention has several operating steps that need to be paid attention to when using the lead box body 1. The specific steps are as follows:

[0039] Step 1: Handle with care: Since each shelf has a limited load-bearing capacity, please be careful not to overload it. At the same time, do not collide or squeeze the box during movement.

[0040] Step 2: Installation and fixing: After the operator selects a location, make sure that the shelf is flush with the ground, and then use bolts or wire ropes to fix it to the wall to avoid vibration.

[0041] Step 3: Storing items: Items in the radioactive material storage lead box should be classified according to different specifications and types, and waterproof measures should be taken to ensure that the materials will not be affected by moisture.

[0042] Step 4: Clearly mark dangerous goods that require warnings or precautions: Please make corresponding signs around the placement area and indicate their names and related prompt information in obvious fonts.

[0043] Step 5: Regular inspection: Regular inspection is an effective means to prevent problems. Please check the storage barrel and the items inside at the specified time, and clean, replace, etc. as needed.

[0044] Finally, the lead box body 1 must be cleaned and disinfected after use to ensure that the contents are safe and reliable when it is reused next time. Only by strictly abiding by each step and rules and regulations can the radioactive storage lead box play its role and ensure the safety of human society and the environment.

[0045] Furthermore, in another embodiment provided by the present invention, the method of using the mobile radiation protection nursing device for nuclear medicine and the method of using the device is as follows when the cover 1.3 is limited and fixed:

[0046] Step 1: First, open the cover 1.3 of the lead box body 1. Further, the operator opens the cover 1.3 that needs to be used on the lead box body 1. Figure 2 Status shown.

[0047] Step 2: Place the items in the lead box body 1. Further, gently place the items to be placed in the lead box body 1 and close the cover 1.3. The opening and closing of the cover 1.3 is a prior art and will not be described in detail.

[0048] Step three, drive the connecting rod 3.3 downward through the linkage mechanism so that it forces the slider 2.2 to slide on the slide rail 2.1 toward the side of the cover 1.3 and abut against it. Furthermore, after the cover 1.3 is blocked, it descends through the threaded transmission of the rotating rod 3.1 and the bracket 3. During the descent, its bottom will rotate on the receiving plate 3.2 and force the receiving plate 3.2 to descend synchronously. During the descent of the receiving plate 3.2, it will force the connecting rod 3.3 to move downward in an arc and press down. During the downward pressure of the connecting rod 3.3, it forces the slider 2.2 to slide on the slide rail 2.1 of the base 2. During the travel of the slider 2.2, it will eventually make the limiting part 2.3 abut against the cover handle 1.4 on the cover 1.3, thereby limiting and fixing the cover 1.3 and improving its stability during blocking.

[0049] After the linkage mechanism in the present invention drives the limiting structure, the four sliders 2.2 will move on the lead box body 1 in an outward expansion trend. At the end of the moving stroke, the limiting portion 2.3 on each slider 2.2 will abut against the cover handle 1.4 on each cover 1.3. Figure 3 Status shown.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
