[0030] This specific implementation is an outdoor fracture emergency self-rescue device, and its structural schematic diagram is as follows Figure 1-Figure 8 shown.

[0031] Example 1

[0032] The device includes a supporting shell 1, an inflatable liner 2 and an automatic inflation component 3. The supporting shell 1 is formed by folding twelve rigid supporting sheets 4. The middle part of the supporting shell 1 bulges outward and an installation cavity 5 is formed inside. The inflatable liner 2 is fixedly connected to the inside of the installation cavity 5. The automatic inflation component 3 is installed on the outside of the supporting shell 1, and the output end of the automatic inflation component 3 is connected to the inflatable liner 2.

[0033] like Figure 5 and Figure 6 As shown: in this embodiment, two layers of Oxford cloth 6 are fixedly connected to the upper and lower sides of the rigid support plate 4, and a high-density sponge 7 is fixedly connected to the inner Oxford cloth 6.

[0034] Since the high-density sponge 7 is relatively soft, it can better contact the fracture site of the patient, prevent the skin from being worn, and achieve better use effect.

[0035] like Figure 4 and Figure 5 As shown: In this embodiment, each rigid support plate 4 includes two carbon fiber plates 8 that can be bent to each other. The carbon fiber plates 8 are trapezoidal structures. The wide sides of the two carbon fiber plates 8 are connected together. In this way, after the two carbon fiber plates 8 are bent, the middle parts thereof can bulge outward and an installation cavity 5 is formed inside.

[0036] like Figure 1 and Figure 2 As shown: In this embodiment, twelve rigid support sheets 4 are sewn and fixed together by two layers of Oxford cloth 6, and two carbon fiber plates 8 are sewn and fixed together by two layers of Oxford cloth 6.

[0037] Specifically, the Oxford cloth 6 is cut into compartments that can be inserted into the carbon fiber plates 8, and the Oxford cloth 6 is connected by sewing. The carbon fiber plates 8 play a role in structural support and shape determination in the cloth, and can be bent with each other.

[0038] like Figure 4 As shown: In this embodiment, two strong magnetic stickers 9 are installed on the head and tail rigid support plates 4, and the two strong magnetic stickers 9 are installed at both ends of the two carbon fiber plates 8. By setting the strong magnetic stickers 9, the support shell 1 can be conveniently mounted on the patient's fracture site for fixation, thereby achieving the purpose of one-handed operation.

[0039] like Figure 1 , Figure 2 and Figure 3As shown: In the present embodiment, the automatic inflation component 3 is an inflation valve of a life jacket, specifically comprising an inflation valve housing 301, an operating rod 302 and a compressed gas cylinder 303. The operating rod 302 is a pull rope. An inflation valve is arranged inside the inflation valve housing 301. The inflation valve can select a life jacket inflation valve. The inflation valve housing 301 is fixedly connected to the outer surface of the rigid support sheet 4. The compressed gas cylinder 303 is a nitrogen cylinder. The compressed gas cylinder 303 is installed at the air inlet end of the inflation valve housing 301. The air outlet end of the inflation valve housing 301 is connected to the inflatable liner 2. The operating rod 302 is used to drive the ejector pin inside the inflation valve housing 301 to puncture the compressed gas cylinder 303 and inflate the inflatable liner 2.

[0040] During the inflation process of the product, liquid nitrogen quickly vaporizes, and the inflatable liner 2 expands and absorbs heat. The device is temperature tested to ensure that it has the function of cooling the affected limb. For example, the initial temperature is displayed at 31.4°C, and then the air valve is pulled. The inflatable liner 2 expands instantly, and the temperature drops to 6.7°C, and then the temperature gradually rises. Ten minutes later, the temperature fluctuates around 15.4°C, which proves that the device can cool the affected limb after releasing the gas, thereby achieving the purpose of reducing inflammation and swelling.

[0041] like Figure 2 , Figure 3 and Figure 7 As shown: In this embodiment, it also includes a controller 10, a pressure sensor 11 and an intelligent air valve 12. The pressure sensor 11 is installed inside the inflatable liner 2, and the intelligent air valve 12 is installed at the air outlet end of the inflation valve housing 301. The pressure sensor 11 and the intelligent air valve 12 are both electrically connected to the controller 10;

[0042] The controller 10 stores the required fixation pressures for different fracture sites, so that the expansion degree of the inflatable liner 2 is controlled by the pressure sensor 11 and the intelligent air valve 12, which not only realizes the customization of the fracture fixation plan, but also expands the scope of application of the device.

[0043] Example 2

[0044] The same as Example 1 is not repeated here, but the difference from Example 1 is that: Figure 3 and Figure 8As shown: in the present embodiment, a hollow rectangular slider 305 is slidably connected to the interior of the inflation valve housing 301, one end of the hollow rectangular slider 305 is connected to the air outlet end of the inflation valve housing 301 through a hose 306, and the other end of the hollow rectangular slider 305 is fixedly connected to a hollow ejector pin 304. The operating rod 302 is a threaded rod, one end of the operating rod 302 is rotatably connected to the hollow rectangular slider 305 through a bearing, and the other end of the operating rod 302 passes through the exterior of the inflation valve housing 301, and the operating rod 302 is threadedly connected to the inflation valve housing 301. In this way, when the operating rod 302 is rotated, the hollow rectangular slider 305 and the hollow ejector pin 304 can be driven to move to the right. After the hollow ejector pin 304 moves, the compressed gas cylinder 303 is broken. At this time, the liquid nitrogen inside is quickly gasified and filled with the inflatable liner 2. Since the operating rod 302 is moved in a rotating manner, it is not only more labor-saving, but also avoids the patient's fracture site from exerting force, making it easier to operate.

[0045] During the inflation process of the product, liquid nitrogen quickly vaporizes, and the inflatable liner 2 expands and absorbs heat. The device is temperature tested to ensure that it has the function of cooling the affected limb. For example, the initial temperature is displayed at 31.4°C, and then the air valve is turned. The inflatable liner 2 expands at an instant, and the temperature drops to 6.7°C, and then the temperature gradually rises. Ten minutes later, the temperature fluctuates around 15.4°C, proving that the device can cool the affected limb after releasing the gas, thereby achieving the purpose of reducing inflammation and swelling.

[0046] Working principle: by selecting twelve foldable rigid support sheets 4, the interior can be bulged to form an installation cavity 5, and an inflatable liner 2 is installed in the installation cavity 5. An automatic inflation component 3 is arranged on the outside of the rigid support sheet 4. When in use, the fractured part of the patient is placed inside the device, and then the head and tail rigid support sheets 4 are fixed together by strong magnetic patches 9. Only one-handed operation is required to make the outer rigid support sheet 4 drive the internal inflatable liner 2 to automatically curl and wrap the affected limb, and then the operating rod 302 is used to make the thimble pierce the compressed gas cylinder 303. At this time, the liquid nitrogen is rapidly gasified, and the inflatable liner 2 expands and absorbs heat. Not only can the inflation realize reliable and effective fixation, but also has the function of cooling the affected limb to achieve the purpose of cold compress and swelling. The fracture emergency self-rescue device can provide fracture patients with fast and effective self-rescue measures in the field, wartime or disaster site, can reduce the cost and burden of fracture treatment, and is conducive to improving the efficiency and success rate of rescue operations. At the same time, the research and development and popularization of such emergency self-rescue devices are also conducive to improving the public's awareness and ability of emergency self-rescue.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
