The warm air can not only increase the air volume, but also wrap the entire wounded person's legs, accelerate the speed of blowing dry the moisture on the legs, and realize the rewarming of the leg wounds. The warm air in the air distribution box 8 can also enter the chest warming box 11, and blow warm air to the wounded person's chest through the seventh air outlet 1101. The chest warming box 11 cooperates with the electric heating pad to keep the front chest and back of the wounded person at a sufficient temperature.

[0051] Please refer to Figures 4-5 The cross section of the second air bag block 4 is triangular, and the pointed end of the second air bag block 4 faces the arc-shaped notch 701. The shape of the second receiving groove 104 matches the shape of the second air bag block 4. The cross section of the fourth air bag block 10 is triangular, and the pointed end of the fourth air bag block 10 faces away from the arc-shaped notch 701. The distance between the front ends of the two second grooves 103 is less than the distance between the rear ends, that is, from the top, the two second grooves 103 are inclined. When the wounded person's legs are placed in the two second grooves 103 respectively, the two legs are spread apart due to the blocking effect of the second air bag block 4. The present application conforms to ergonomics, and the spread of the wounded person's legs can improve comfort.

[0052] Please refer to Figures 11-13The gas distribution box 8 comprises a box body 801, a first partition plate 802, a second partition plate 803, a third partition plate 804 and a fourth partition plate 805. The first partition plate 802 and the second partition plate 803 are both arranged at the middle part of the box body 801, and the first partition plate 802 and the second partition plate 803 divide the interior of the box body 801 into a first chamber 806. The third partition plate 804 is arranged in the box body 801 and located at the front side of the first partition plate 802, and the first partition plate 802 and the third partition plate 804 divide the interior of the box body 801 into a second chamber 807 and a third chamber 808. The fourth partition plate 805 is arranged in the box body 801 and located at the rear side of the second partition plate 803, and the second partition plate 803 and the fourth partition plate 805 divide the interior of the box body 801 into a fourth chamber 809 and a fifth chamber 810. Please refer to Figures 12-13 The third gas bag block 9 is located below the second chamber 807, the fifth gas outlet 80101 is located below the third chamber 808, the fourth gas bag block 10 is located below the fourth chamber 809, and the sixth gas outlet 80102 is located below the fifth chamber 810.

[0053] Please refer to Figure 13 The first partition plate 802 is provided with a first gas conveying passage 80201 and a second gas conveying passage 80202, the second chamber 807 is communicated with the first chamber 806 through the first gas conveying passage 80201, and the third chamber 808 is communicated with the first chamber 806 through the second gas conveying passage 80202. The second partition plate 803 is provided with a third gas conveying passage 80301 and a fourth gas conveying passage 80302, the fourth chamber 809 is communicated with the first chamber 806 through the third gas conveying passage 80301, and the fifth chamber 810 is communicated with the first chamber 806 through the fourth gas conveying passage 80302.

[0054] Please refer to Figure 9 and Figure 15 The ventilation pipe 14 is provided between the chest warming box 11 and the gas distribution box 8, the first end of the ventilation pipe 14 is communicated with the interior of the chest warming box 11, and the second end of the ventilation pipe 14 is communicated with the first chamber 806. Please refer to Figure 10 、 Figure 11 、 Figure 13 and Figure 14 The top surface of the box body 801 and located above the first chamber 806 is provided with a fifth gas conveying passage 811, the second end of the gas conveying pipe 12 is connected with the first chamber 806 through the fifth gas conveying passage 811, the fifth gas conveying passage 811 has a plurality of fifth gas conveying passages 811, and the plurality of fifth gas conveying passages 811 are uniformly distributed along the length extension direction of the first chamber 806.

[0055] When the warm air enters into the air distribution box 8 through the air pipe 12 and the hose 13, the warm air will first enter into the first chamber 806, and then the warm air will be evenly distributed and enter into the second chamber 807, the third chamber 808, the fourth chamber 809 and the fifth chamber 810 through the first air distribution channel 80201, the second air distribution channel 80202, the third air distribution channel 80301 and the fourth air distribution channel 80302 respectively. The warm air entering into the second chamber 807 will be sprayed from the third air outlet 901, the warm air entering into the third chamber 808 will be sprayed from the fifth air outlet 80101, the warm air entering into the fourth chamber 809 will be sprayed from the fourth air outlet 1001, and the warm air entering into the fifth chamber 810 will be sprayed from the sixth air outlet 80102. In addition, the warm air in the first chamber 806 will also enter into the chest warming box 11 through the air pipe 14 and be sprayed from the seventh air outlet 1101.

[0056] That is, the warm air entering into the first chamber 806 will be dispersed from the center to the periphery, so that the warm air blown to the arm side, the leg side and the chest side of the wounded person is uniform in size, and the situation that the air force blown to one side is greater than that blown to the other two sides will not occur, so that the stability of the blown warm air and the effect of the wound rewarming operation can be ensured.

[0057] Please refer to Figure 1 , Figure 4 , Figure 9 and Figure 10 , the chest warming box 11 is located above the air distribution box 8, and in the present application, the middle of the heat preservation cover 7 is high and the two sides are low, and the central position is protruded upward, so that there is enough space in the heat preservation cover 7 to accommodate the chest warming box 11. The position of the bottom end of the chest warming box 11 is higher than the position of the top end of the arc-shaped notch 701, so that when the heat preservation cover 7 is closed, there is enough gap between the chest warming box 11 and the chest of the wounded person, and the chest of the wounded person will not be compressed, and the wounded person can breathe smoothly.

[0058] Please refer to Figure 1 , Figure 4 , Figure 9 , Figure 10 and Figure 16 , the present application also includes an air exhaust assembly, which is arranged between the two air distribution boxes 8 away from the side of the arc-shaped notch 701. When the heat preservation cover 7 is closed, blowing warm air into the space enclosed by the heat preservation cover 7 and the support plate 1 will cause the air pressure in the space to increase, and if the air in the space is not exhausted in time, the air will be sprayed from the position of the arc-shaped notch 701, causing the wounded person to have difficulty breathing, and the air exhaust assembly in the present application can solve this problem.

[0059] Please refer to Figure 4 , Figure 9 , Figure 10 and Figure 16The exhaust assembly comprises an air inlet cylinder 15, an air guide cylinder 16 and three exhaust pipes 17. The air inlet cylinder 15 is internally hollow, and a plurality of air inlet holes 1501 are uniformly distributed on the side wall of the air inlet cylinder 15. The bottom of the air inlet cylinder 15 is provided with a second connecting plate, and the air inlet cylinder 15 is fixedly connected to the air distribution box 8 through the second connecting plate.

[0060] The air guide cylinder 16 is arranged on the top surface of the air inlet cylinder 15, and the inside of the air guide cylinder 16 is hollow and connected to the inside of the air inlet cylinder 15. The three exhaust pipes 17 are arranged on the side wall of the air guide cylinder 16 and are radially and uniformly distributed. The first end of the exhaust pipe 17 is connected to the inside of the air guide cylinder 16, and the second end of the exhaust pipe 17 extends out of the heat preservation cover 7 through the top surface of the heat preservation cover 7.

[0061] When the air pressure in the space enclosed by the heat preservation cover 7 and the support plate 1 increases, the gas will first enter the air inlet cylinder 15 through the plurality of air inlet holes 1501, then enter the three exhaust pipes 17 through the air guide cylinder 16, and finally be discharged to the outside of the heat preservation cover 7 through the second end of the exhaust pipe 17, thereby reducing the air pressure on the inside of the heat preservation cover 7. The position of the arc-shaped notch 701 only has a small amount of gas sprayed out, so it will not affect the breathing of the injured person, further increasing the comfort of the injured person.

[0062] Please refer to Figure 10 and Figure 16 The middle part of the exhaust pipe 17 is in a U shape, and the length of the exhaust pipe 17 is greater than twice the outer diameter of the air inlet cylinder 15. The length and tortuosity of the exhaust pipe 17 are increased, which can prevent cold air outside the heat preservation cover 7 from flowing back into the inside of the heat preservation cover 7. If the cold air enters from the top of the exhaust pipe 17, on the one hand, due to the long length of the exhaust pipe 17, the cold air will be blown out by the warm air before it reaches the position of the air inlet cylinder 15, and on the other hand, since most of the exhaust pipe 17 is located on the inside of the heat preservation cover 7, the cold air will soon be heated to become warm air, so the injured person on the inside of the heat preservation cover 7 will not be blown by cold air at all.

[0063] Please refer to Figures 5-7 The front end of the first groove 101 is higher than the rear end, and the front end of the second groove 103 is higher than the rear end. The inside of the support plate 1 is provided with four drainage channels 105, the water inlets of the four drainage channels 105 are respectively connected to the bottom of the rear end of the two first grooves 101 and the two second grooves 103, and the water outlets of the four drainage channels 105 are all located on the bottom surface of the support plate 1.

[0064] When the wounded person lies on the top surface of the support plate 1 after washing the wound surface caused by the explosion with water, the water droplets attached to the arms and legs of the wounded person will flow down to the bottom surface of the first groove 101 and the second groove 103, and since the first groove 101 and the second groove 103 are both inclined downward, the water droplets will flow to the position of the water inlet of the drainage channel 105, and when warm air is blown to the limbs through the first air bag block 3 and the second air bag block 4, the water droplets will be blown into the drainage channel 105 and discharged through the water outlet of the drainage channel 105, thereby accelerating the drying speed of the limbs of the wounded person.

[0065] Please refer to Figures 2-3 and Figures 5-7 The present application also includes a plurality of arc-shaped pads 18, four electric heating rings 19 and four support legs 20. The plurality of arc-shaped pads 18 are fixedly arranged at the bottom of the first groove 101 and the second groove 103, and the bottom surface of the arc-shaped pad 18 is provided with a water passage 1801. When the arms of the wounded person are placed in the first groove 101 and the legs are placed in the second groove 103, the plurality of arc-shaped pads 18 can elevate the arms and legs of the wounded person, so that the water droplets flowing down will not adhere to the limbs, and can smoothly fall down, and the falling water droplets can pass through the water passage 1801 to the position of the water inlet of the drainage channel 105 and will not be blocked by the arc-shaped pad 18. Therefore, the present application can quickly blow away the water droplets flowing down from the support plate 1.

[0066] Please refer to Figures 2-3 The four electric heating rings 19 are arranged at the water outlet of the drainage channel 105, respectively, and the electric heating ring 19 is provided with an electric heating wire inside and is electrically connected with the controller. The four support legs 20 are fixedly arranged at the four corners of the bottom surface of the support plate 1. Since the water droplets are easily frozen into ice in cold regions, the electric heating ring 19 can be controlled by the controller to generate heat, so as to prevent the water outlet of the drainage channel 105 from being frozen, and the support leg 20 can make the support plate 1 have a certain distance from the ground, so that the water outlet of the drainage channel 105 will not be blocked by the ground. Therefore, the water droplets entering the drainage channel 105 can be smoothly discharged, so as to quickly dry and rewarm the wound of the wounded person.
