[0008] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1
[0009] like Figure 1 , 5As shown in 6, the bracket 1 is slidably connected to the connecting component 3; the end of the connecting component 3 is movably connected to the fixing device 2; the connecting component 3 includes a slider 301, a knob 303, a screw 302, a connector 304, a torsion spring 305, a connecting rod 306, a telescopic block 307, and a telescopic shaft 308; the slider 301 is slidably connected to the bracket 1, and the inner thread of the slider 301 is connected to the screw 302; a hole is provided inside the screw 302 to rotatably connect the connector 304; a knob 303 is provided on the top of the connector 304, and a torsion spring 305 is provided in the middle 05, a telescopic shaft 308 is symmetrically arranged at the bottom; the telescopic shaft 308 is rotatably connected to the connecting rod 306; a telescopic block 307 is arranged at the end of the connecting rod 306; the connecting head 304 is divided into three sections, the diameter of the upper end is consistent with the inner hole of the screw 302, and the diameters of the middle section and the end are reduced successively; one end of the torsion spring 305 is fixedly connected to the upper cross section of the connecting head 304, and the end is fixedly connected to the bottom of the inner hole of the screw 302; the connecting rod 306 is L-shaped; sliding grooves 102 are respectively arranged on both sides of the end of the inner hole of the screw 302 to movably connect the telescopic block 307; The bracket 1 includes a support plate 101, a slide groove 102, and a connecting shaft 103; the support plates 101 are arranged in a circular array of 8 pieces, and the support plates 101 are rotatably connected by the connecting shaft 103. The middle of the support plate 101 is provided with a slide groove 102 for sliding connection with the slider 301; the slide groove 102 between every two support plates 101 is connected for the slider 301 to slide; In this embodiment, the working principle of the connecting assembly 3 is as follows: by twisting the knob 303, the connecting head 304 is driven to rotate, and at this time, the telescopic shaft 308 at the bottom drives the connecting rod 306 to rotate. At the same time, since the telescopic block 307 set at the end of the connecting rod 306 is limited by the slide grooves 102 on both sides of the end of the inner hole of the screw rod 302, the connecting rod 306 can only drive the telescopic block 307 to slide in the slide groove 102, so as to control the telescopic block 307 to connect or disengage from the connecting groove 207, so as to achieve the installation and disassembly of the fixed mainboard 201; After the fixed mainboard 201 is installed, the slider 301 is slid along the slide groove 102 on the support plate 101 to adjust the position of the fixed mainboard 201 according to the affected part. After the adjustment is completed, the screw rod 302 is rotated, and the screw rod 302 is threadedly connected with the slider 301 to push the fixed mainboard 201 close to the affected part for clamping and fixing, and the clamping force is adjusted at the same time; In this embodiment, the support plates 101 are connected in a rotatable and detachable manner. When the bracket 1 needs to be carried, a connection of the support plate 101 can be removed, and the support plate 101 can be turned over and folded, so that the bracket 1 can be folded and stored; In this embodiment, the design of the connecting component 3 allows for quick assembly and disassembly of the fixing device 2, and can respond quickly in emergency situations, solving the problem of large-volume devices being difficult to carry and quickly deploy in the prior art. The connecting component 3 is compactly designed and does not take up too much space, making the entire first-aid fixing device 2 more portable. Through the threaded connection of the screw 302 and the slider 301, the position of the fixed mainboard 201 can be stably adjusted, and the clamping force can be adjusted, thereby improving the stability and reliability of the fixing device 2. After use, the telescopic shaft 308 drives the connecting rod 306 to rotate by rotating the knob 303, thereby pulling back the telescopic block 307, facilitating the removal of the fixed mainboard 201 and the storage of the device, solving the problem of the fixing device 2 being difficult to store in the prior art. In this embodiment, the bracket 1 is composed of 8 support plates 101, which can be folded backwards to achieve a compact storage state, which is convenient for carrying. This solves the problem that the large-scale fixing device 2 in the prior art is inconvenient to carry. The design of the bracket 1 allows for rapid deployment and assembly, so that it can be quickly put into use in an emergency, thereby improving the timeliness of first aid; In this embodiment, the slider 301 can slide along the slide groove 102 on the support plate 101, so that when the injured part needs to be observed, a single support plate 101 can be relaxed, and then the support plate 101 can be rotated to observe and treat the injured part without affecting the overall fixation effect of the bone joint. Example 2
[0010] like Figure 1-4 As shown, the fixing device 2 includes a fixed mainboard 201, a telescopic plate 202, a telescopic column 203, a telescopic spring 204, a limit groove 205, a semiconductor thermoelectric cooling sheet 206, and a connecting groove 207; a connecting groove 207 is arranged at the top of the fixed mainboard 201 to movably connect the telescopic block 307, two hollow cavities are arranged in the fixed mainboard 201, a plurality of limit grooves 205 are respectively arranged at both ends of the upper cavity, and a semiconductor thermoelectric cooling sheet 206 is arranged in the lower cavity; telescopic springs 204 are symmetrically arranged on both sides of the front end of the telescopic plate 202; a telescopic column 203 is arranged at the front end of the telescopic spring 204 to movably connect the limit groove 205; telescopic plates 202 are arranged at both ends of the fixed mainboard 201; In this embodiment, the telescopic principle of the fixing device 2 is as follows: by pulling the telescopic plate 202, the telescopic column 203 is retracted and limited by the limiting groove 205, and the telescopic column 203 is retracted by the elastic action of the rear end spring, so that the telescopic plate 202 can be pulled out. After the telescopic plate 202 is pulled to a suitable position and stops, the telescopic column 203 is pushed into the limiting groove 205 by the resetting action of the spring, so that the telescopic plate 202 can be fixed. In this embodiment, by fixing the semiconductor thermoelectric cooling sheet 206 disposed in the main board 201, cold compress or hot compress can be adjusted according to the condition of the affected part and the needs of the patient. Cold compress can reduce the inflammatory response of the injured part and reduce the sensitivity of the nerve endings, thereby alleviating the pain. By contracting the blood vessels and reducing the blood flow to the injured part, it helps to control swelling and bleeding, slow down cell metabolism, reduce the inflammatory response of the injured part, and create a good environment for tissue healing. In this embodiment, the surface of the fixed main board 201 can be covered with non-woven fabric, cotton cloth, gauze or silicone material to absorb moisture, prevent the hot and cold compress surface from directly contacting the skin, provide uniform hot and cold transfer, and reduce the discomfort of direct contact with the skin; In this embodiment, the semiconductor thermoelectric cooling sheet 206 is a prior art, and its working principle is that when current passes through the junction of two different conductors or semiconductor materials, heat absorption or heat release will occur. The semiconductor thermoelectric cooling sheet 206 uses this principle to achieve the function of cooling or heating. In this embodiment, it is taken into consideration during the design that the device is an emergency device that needs to be easy to carry. Other cooling and heating devices have large structures and complex operating conditions. The semiconductor thermoelectric cooling chip 206 has the advantages of small size, light weight, no vibration, no noise, and easy control, and is more suitable for use in this device.
[0011] In summary, the present invention provides a bracket 1 formed by an array of eight support plates 101. When storage is required, the support plates 101 can be folded in reverse, that is, the support plates 101 can be folded and stored, and the fixed main board 201 is connected through the connecting component 3. After use, the knob 303 is rotated to make the telescopic shaft 308 drive the connecting rod 306 to rotate, so that the telescopic block 307 is pulled back and separated from the connection slot 207 at the top of the fixed main board 201. The fixed main board 201 can be taken out, so that the device can be stored for easy carrying; At the same time, by setting the telescopic plates 202 at both ends of the fixed main board 201, when performing first aid for bone trauma, the telescopic plates 202 can be pulled out from the fixed main board 201 according to the size of the patient's injured limb, so that the fixing length can be quickly adjusted to adapt to the on-site conditions, and after fixation, it can provide a more uniform pressure distribution and a more stable fixation.
