[0002] X-ray examination is a commonly used method in medical diagnosis. However, X-rays pose certain radiation hazards to the human body. Currently, when performing radiological diagnosis on infants and young children who are newly born or recently born in the ICU, mobile X-ray equipment is moved to the ward for filming. To prevent other infants and young children in the ICU ward and radiation personnel from being exposed to unnecessary radiation, the infants to be examined are placed in infant protection boxes to prevent leakage of X-rays. However, the outer walls of infant X-ray protection boxes currently on the market are mostly made of lead plates. The overall weight and volume are large, making them inconvenient to move and store, not convenient to use, and the shielding effect of X-rays is limited. Since infants and young children are sensitive to radiation and have weak constitutions, this special group of infants and young children requires more effective protection measures.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 9 As shown, a radiation protection device for infants and young children mainly includes several skeletons 1, a protection structure 2, a protection reinforcement structure 3, a movable support 5, an upper connecting ring 6, and a lower connecting ring 7.

[0033] The upper connecting ring 6 and the lower connecting ring 7 of the present application are both made of flexible materials and have a hollow structure therein. Wires are passed through the upper connecting ring 6 and the lower connecting ring 7 .

[0034] Several skeletons 1 are connected between the upper connecting ring 6 and the lower connecting ring 7. These skeletons 1 are evenly and symmetrically distributed between the upper connecting ring 6 and the lower connecting ring 7. The upper connecting ring 6, the lower connecting ring 7, and the skeletons 1 constitute the main frame of this application. Preferably, 8-20 skeletons 1 are provided, each of which is linear or arc-shaped. The length of the skeleton 1 can be determined based on the overall size of the protective device.

[0035] The skeleton 1 of the present application is made of a material that has high strength and light weight at room temperature, can be deformed when heated to 60-70°C, and has a certain flexibility (such as acrylonitrile-butadiene-styrene copolymer (ABS), aluminum alloy, carbon fiber, tungsten, molybdenum, stainless steel, titanium, nickel-titanium alloy, etc.). In order to achieve the change in flexibility of the skeleton 1 after heating, the skeleton 1 of the present application is set as a hollow structure, and a heating element 13 is embedded inside. The two ends of the heating element 13 are respectively connected to the wires in the upper connecting ring 6 and the lower connecting ring 7. The wire in the upper connecting ring 6 is led out from the upper connecting ring 6 and connected to the negative pole of the power supply. The wire in the lower connecting ring 7 is led out from the lower connecting ring 7 and connected to the heating control switch 8. The heating control switch 8 is connected to the positive pole of the power supply, thereby forming a closed loop.

[0036] For example, 12 skeletons 1 are set between the upper connecting ring 6 and the lower connecting ring 7. The equivalent circuit is as follows: Figure 6 As shown, the heating element 13 embedded in each skeleton 1 is equivalent to a resistor (R1~R12). The resistors are connected in parallel with one end directly connected to the negative pole of the power supply (U-) through a wire, and the other end is connected to the positive pole of the power supply (U+) through a wire of a series control switch (K). After the switch K is turned on, the current flows through the resistors R1~R12, the resistors will heat up, and the temperature of the skeleton 1 will increase. After the power is continuously supplied for a period of time, the temperature of the skeleton 1 rises to 60-70 degrees, the molecular structure of the skeleton material changes, its flexibility increases, and it is easy to deform, so that the skeleton 1 can be bent into a suitable shape by external force; and when the heating is stopped and the temperature is restored to room temperature, the molecules of the skeleton material are rearranged, and the high strength and non-deformation characteristics are restored, and good plasticity is maintained.

[0037] Specifically, the heating element 13 of the present application can adopt a flexible resistance heating wire or a thin film heating plate; the wires in the upper connecting ring 6 and the lower connecting ring 7 are made of high-temperature resistant and flexible wires, such as silicone wires or Teflon wires, to ensure that the circuits will not break or be damaged when the protective device is folded and stored.

[0038] This application further optimizes the structure of the skeleton 1: the skeleton 1 comprises a plurality of linear skeleton segments 11 arranged sequentially. The skeleton segments 11 are hollow structures made of low-cost ABS or aluminum alloy, and a heating element 13 is embedded within the hollow structure. Adjacent skeleton segments 11 are connected by skeleton segment connectors 12, which are made of shape memory alloy wire (e.g., nickel-titanium alloy). The ends of the shape memory alloy wire are fixed to adjacent skeleton segments 11 (preferably embedded connections) and connected to the heating element 13, maintaining a certain tension in their natural state. At room temperature, the shape memory alloy wire is in a martensitic state, possessing a certain strength and rigidity, and can firmly connect and fix adjacent skeleton segments 11. When the temperature rises to a certain level (close to 70 degrees), the nickel-titanium alloy will undergo a phase transformation from the martensite phase to the austenite phase. During this process, the material will become soft, and it is easy to perform shaping operations on the skeleton 1. If it has been deformed before, it may return to its original memorized shape, and the size may change (if it was in a compressed state before, the size will become larger when the shape is restored; if it was in a stretched state before, the size may become smaller when the shape is restored) (References: 1.

[0039] Preferably, the present application can coat the surface of the skeleton 1 with a coating that is resistant to high temperatures, wear-resistant and has a low friction coefficient, such as a polytetrafluoroethylene coating, to reduce the friction resistance of the skeleton during unfolding and folding and increase the service life of the skeleton 1.

[0040] In the present application, the main frame is also covered with a protective structure 2, and the main frame and the protective structure 2 form a protective cover. The protective structure 2 can be fixed to the inner or outer side of the main frame by sewing or bonding, and the protective structure 2 can also be fixed on the inner and outer sides of the main frame at the same time. At this time, the main frame is completely wrapped in the inner and outer layers of the protective structure 2, forming a continuous protective barrier. The existence of the skeleton 1 cannot be observed from the outside, and the entire protective cover remains flat and smooth in appearance, without affecting its overall aesthetics. In addition, in the process of fixing the protective structure 2 to the skeleton 1 in the main frame, it is necessary to ensure that the connection between the skeleton 1 and the protective structure 2 is firm and reliable, and at the same time, avoid displacement or loosening of the skeleton 1 between the inner and outer layers of the protective structure 2.

[0041] Specifically, the protective structure 2 of the present application is layered, including a radiation protection layer and high-performance fiber layers located on both sides of the radiation protection layer. The radiation protection layer is formed by stacking several layers of radiation protection sheets. The radiation protection sheets are made of new lead-free composite radiation protection materials, which are soft and have good X-ray shielding properties. The radiation protection sheets are preferably 4 to 8 layers, and the thickness and number of layers of the radiation protection sheets can be adjusted according to actual needs. The high-performance fiber layer is made of a material with certain elasticity and flexibility, such as aramid fiber or ultra-high molecular weight polyethylene fiber, which can not only ensure the effective wrapping and fixation of the skeleton 1, but also provide additional protection for the protective device.

[0042] Preferably, the present application may provide an observation window 21 on the protective structure 2 for observing the condition of the child in the protective device at any time.

[0043] In addition, in order to resolve the contradiction between the protective effect and the reduced flexibility of the device due to excessive weight, the present application can reduce the thickness and number of layers of the protective structure 2, making the device lighter and more flexible to fold and unfold. At the same time, to address the problem of the shielding effect being weakened due to the thinness of the protective structure 2, a separate protective reinforcement structure 3 with the same overall structure as the protective structure 2 can be configured. The material selected for the protective reinforcement structure 3 is the same as that of the radiation protection layer or the protective structure 2. The protective reinforcement structure 3 is covered on the protective cover, thereby enhancing the shielding effect of the protective device of the present application, so that the present application has both excellent protective performance and flexibility of use.

[0044] As a preferred embodiment, the present application further provides a drawstring 4 in the hollow structure of the lower connecting ring 7, with both ends of the drawstring 4 extending outside the lower connecting ring 7. The setting of the drawstring 4 allows the protective cover to be folded. The drawstring 4 can be made of nylon, polyester fiber, plastic-coated steel wire, etc. The protective cover of the present application can be folded manually or electrically:

[0045] (1) Electric folding: The structure of the electric rope winding device 9 is as follows Figure 8 As shown, the protective cover comprises a base 91, with brackets 92 mounted on either side. A reel 93 is mounted on the two brackets 92 and is rotatably connected to them. One end of the reel 93 is connected to the output of a motor 94 via a gear pair. To fold the protective cover, one end of the draw cord 4 is secured to the base 91 and the other end to the reel 93. The motor 94 is then started, and the gear pair drives the reel 93 to rotate, thereby winding the draw cord 4 around it. As the draw cord 4 is pulled, the individual frames 1 begin to move closer together, and the entire device is transformed into a folded state. The entire process is quick and smooth.

[0046] (2) Manual folding: The structure of the manual rope reel 10 is as follows Figure 9As shown, the manual cord reel 10 is similar in structure to the electric cord reel 9, except that one end of the reel 93 is connected to a rotary adjustment lever 101 instead of a motor 94. To fold the protective cover, the user rotates the rotary adjustment lever 101, which winds the draw cord 4. As the draw cord 4 is pulled, the frames 1 move closer together, folding.

[0047] Preferably, after the protective cover is completely folded, a fixing device, such as a clip, hook, or magnetic device, can be provided to fix the folded frame together to maintain the stability of the folded state. In addition, as needed, a draw cord installation channel can be added on the central outer wall of the protective cover, with a built-in draw cord 4 to increase the smoothness and convenience of the folding function.

[0048] As a preferred embodiment, the present application provides a fixing member and a movable support member 5 below the protective cover.

[0049] Specifically, the fixing part is connected to the lower connecting ring 7, and a connecting belt, a suction cup and other structures can be selected. The setting of the fixing part can connect the protective cover to the X-ray examination bed or infant incubator after shaping, ensuring that no displacement occurs during the examination process.

[0050] The movable support member 5 includes a plurality of telescopic support legs 51, and the plurality of telescopic support legs 51 are evenly distributed at the bottom of the protective cover and at positions corresponding to the skeleton 1. The telescopic support legs 51 of the present application have a height adjustment function, which can be achieved by mechanical telescopic methods such as hydraulic telescopic, electric telescopic, threaded rotation or latch positioning. The maximum height of the telescopic support legs 51 exceeds 1.5 meters, which is enough to position the protective cover above the infant incubator. When the protective cover moves to the appropriate position, the height of the telescopic support legs 51 is lowered so that the protective cover covers the infant incubator. The present application connects a caster 52 with a locking function to the lower end of the telescopic support leg 51, and the caster 52 can conveniently move or prevent the entire device from moving as needed.

[0051] Example 1

[0052] The hollow aluminum alloy skeleton segments 11, with an inner diameter of 1 cm and an outer diameter of 2 cm, contain built-in resistance heating wires, each measuring 20 cm. Fifteen of these segments are connected end-to-end in series to form a single skeleton 1. The connections between the skeleton segments 11 are formed from spring-shaped shape memory alloy wire (nickel-titanium alloy), with both ends embedded and fixed within adjacent skeleton segments 11. Each skeleton 1 is approximately 3.14 meters long. The 12 skeletons 1, upper connecting rings 6, and lower connecting rings 7 form the umbrella-shaped main frame. When fully extended, the main frame has an angle of 60 degrees, and its maximum coverage area is a circle with a radius of 2.73 meters. A telescopic support leg 51 is attached to the lower end of each of the first, fourth, seventh, and tenth skeletons 1. Locking casters 52 are fitted at the lower end of the telescopic support legs 51. Protective structures 2 are secured to both the inner and outer sides of the main frame, completely encasing the main frame within these two layers of protective structures 2, forming an invisible skeleton.

[0053] The method of using this embodiment is as follows:

[0054] (1) Preheating and unfolding: Turn on the heating power supply and turn on the heating control switch 8. Keep the power on for a while until the temperature of the main frame rises to below 70 degrees. When the skeleton 1 becomes soft and can be easily bent, stop heating. Then, gradually loosen the pull rope 4, causing the skeleton to gradually unfold under the action of the memory alloy wire and the skeleton segments.

[0055] (2) Positioning: Raise the height of the protective cover by adjusting the height of the telescopic support legs 51 so that the bottom of the protective cover is located above the infant incubator; unlock the casters 52, push the entire device to the desired position, and then lock the casters 52 to secure it; then lower the height of the telescopic support legs 51 so that the top of the protective cover just covers the infant incubator. At this point, the protective cover can completely cover the incubator;

[0056] (3) Fixing: Fix the protective cover to the infant incubator with fixings. Use the electric rope winding device 9 or the manual rope winding device 10 to properly tighten the bottom pull rope 4 to minimize the X-ray leakage during the inspection process;

[0057] (4) Inspection: Insert the head of the X-ray device into the upper connecting ring 6 of the protective cover, and then perform digital DR photography or X-ray exposure;

[0058] (5) Folding and storage: After the inspection is completed, release the fixation and loosen the bottom draw cord 4. By adjusting the height of the telescopic support legs 51 and cooperating with the casters 52, the entire device can be moved away for the next inspection or storage.

[0059] After use, the protective device can be folded and tightened manually or electrically by drawstring. The folded protective device can be placed in a dedicated storage box or cabinet for next use.
