[0002] Severely injured patients refer to those who are critically injured or seriously injured. Considering the life support and treatment capabilities of the device, it can be used to transport moderately and severely injured patients who are judged by doctors to be suitable for short-term and medium-term air transport (including moderately injured patients with symptoms such as brain nerve damage, heart, lung, bronchial damage, and internal organ damage). In the field of emergency medical rescue, timely treatment of seriously injured patients is crucial. In many emergency situations, such as battlefields and disaster sites, the injured must be treated quickly, usually by helicopters, civil airliners or other aircraft to quickly send the injured to the hospital.

[0046] Example 1

[0047] The embodiment of the present invention provides a seriously injured person air-to-ground transport device such as Figure 1As shown, it includes: a bearing unit 1, a wheel frame unit 2, and a connecting unit 3. The bearing unit 1 includes a support cabin 11, and the support cabin 11 is used to bear the wounded. When in use, the wounded is placed on the support cabin 11; the wheel frame unit 2 is arranged at the bottom of the support cabin 11, and the wheel frame unit 2 can drive the bearing unit 1 to move, so as to facilitate the transfer of the wounded. The wheel frame unit 2 includes a support assembly 21 and two groups of roller assemblies 22. The support assembly 21 is arranged at the bottom of the support cabin 11, and the two groups of roller assemblies 22 are symmetrically arranged at the bottom end of the support assembly 21. The support assembly 21 is used to support the roller assembly 22, and the roller assembly 22 includes a U-shaped rod 221 and two rollers 222. The middle part of the U-shaped rod 221 is rotatably connected to the support assembly 21, and the two rollers 222 are respectively The two rollers 222 are respectively arranged at the two ends of the U-shaped rod 221, that is, the U-shaped rod 221 can rotate relative to the support assembly 21, thereby driving the two rollers 222 to rotate, and the angles of the two rollers 222 in the vertical direction can be adjusted; the connecting unit 3 is used to achieve connection and fixation with the civil aviation passenger aircraft, and the connecting unit 3 includes two fixing plates 31 and at least two locking structures 32. The two fixing plates 31 are respectively rotatably connected to the U-shaped rods 221 of the two groups of roller assemblies 22, and the fixing plates 31 can rotate relative to the U-shaped rod 221. The two locking structures 32 are respectively arranged on both sides of the fixing plate 31, and the locking structure 32 is used to connect the fixing plate 31 to the fixing groove on the aircraft floor rail. The device can realize rapid transportation on the aircraft and on the ground. Specifically, when in use, the injured person is placed on the support cabin 11, and the entire bearing unit 1 can be moved by the wheel frame unit 2 arranged at the bottom of the support cabin 11, so as to facilitate the movement of the injured person on the ground. When the injured person is placed on the civil airliner, the U-shaped rod 221 is first rotated to make the rollers 222 at both ends of the U-shaped rod 221 separate from the aircraft floor, and the bearing unit 1 is supported by the U-shaped rod 221, and then the fixing plate 31 is rotated to make the fixing plate 31 abut against the aircraft floor. At this time, the entire bottom surface of the fixing plate 31 is parallel to and in contact with the aircraft floor, and there is no tilt. Then, the fixing plate 31 is connected and fixed to the aircraft floor guide rail through the locking structure 32, so as to complete a stable connection on the civil airliner. When the injured person is transferred to the hospital after getting off the plane, the locking structure 32 can be released, and the fixing plate 31 and the roller 222 can be rotated in the opposite direction to make the rollers 222 at both ends of the U-shaped rod 221 contact with the aircraft floor again, so as to achieve the purpose of ground transportation again. The device can be used in both civil aviation passenger aircraft and ground transportation vehicles to realize rapid air-ground combined transportation.

[0048] In order to adapt to various types of civil aircraft, such as Figure 2As shown, further, the fixed plate 31 includes a plurality of plate bodies 311, the plurality of plate bodies 311 are arranged in a straight line, and the plurality of plate bodies 311 are connected by a first hinge 314, the plate body 311 located in the middle is rotatably connected to the U-shaped rod 221, and the locking structure 32 is arranged on the plate bodies 311 located at both ends. In this embodiment, there are three plate bodies 311, two plate bodies 311 are respectively arranged on both sides of the other plate body 311, and the two plate bodies 311 are connected by the first hinge 314 so that they can be rotated relative to the other plate body 311, so that they can be folded. This is because the distance between the two guide rails on the floor of many civil aircraft is very wide (mostly between 57cm-90cm), and many are greater than the distance between the two rollers 222. If the fixed plate 31 is not set to such a foldable structure, the U-shaped rod 221 will be stuck and unable to rotate, thereby failing to achieve the fixing effect. The distance between the two rollers 222 cannot be set wider than the distance between the two guide rails (the distance between the two rollers 222 in this embodiment is about 45cm-55cm). On the one hand, this increases the cost, and on the other hand, it also increases the weight, which is not conducive to the flight of the aircraft.

[0049] like Figure 2 As shown, further, multiple plates 311 are respectively provided with multiple connection holes 312. In this embodiment, the connection holes 312 are long strips, but other shapes such as circles can be used. This embodiment provides a specific method of a locking structure 32, which includes a connecting bolt 321 and a fixing block 322. Figure 4 As shown, the connecting bolt 321 includes two circular clamps and a connecting shaft, the two circular clamps are symmetrically arranged at one end of the connecting shaft, the two circular clamps and the connecting shaft are T-shaped, the two circular clamps are used to be clamped in the aircraft floor rail, and the connecting shaft is passed through one of the connecting holes 312. Because the guide groove on the aircraft floor rail is special and wavy, when the two circular clamps are combined together, the arcs of the two clamps match the guide groove on the guide rail, so that clamping can be achieved and will not shift. Under vibration, turbulence, rapid acceleration and deceleration conditions, it has an anti-loosening effect and is more stable; the fixing block 322 is located on the plate body 311, and the end of the connecting shaft away from the circular clamp is threadedly connected to the fixing block 322. When connecting the plate body 311 to the floor rail, the connecting bolt 321 is passed through the connecting hole 312, and the two circular clamps are clamped in the aircraft floor rail. The circular clamps are slightly moved, and then the fixing block 322 and the connecting shaft thread are tightened. The plate body 311 is fixed to the aircraft floor rail through the fixing block 322 to achieve a stable connection.

[0050] like Figure 2As shown, this embodiment provides a way of rotationally connecting the plate body 311 and the U-shaped rod 221. Furthermore, the rotationally connecting structure of the plate body 311 and the U-shaped rod 221 includes: the side wall of the first sleeve 313 is fixed to one side of the plate body 311 located in the middle, the first sleeve 313 is sleeved on the U-shaped rod 221, and the first sleeve 313 is rotationally connected to the U-shaped rod 221. The first sleeve 313 in this device is an integral structure with one side of the plate body 311 in the middle. Among them, an extension plate is also provided between the first sleeve 313 and the connected plate body 311, so that when the entire fixed plate 31 is flipped, the entire bottom surface of the fixed plate 31 is in contact with the aircraft floor.

[0051] Example 2

[0052] As a further improvement on Example 1, Figure 1 As shown, further, the support assembly 21 is provided with two groups, and the two groups of support assemblies 21 are symmetrically arranged. Each group of support assemblies 21 includes two support rods 211, and the two support rods 211 are symmetrically arranged at the bottom of the support cabin 11. The support rods 211 are hinged to the bottom of the support cabin 11, and the middle parts of the two support rods 211 are hinged. The two support rods 211 can rotate relative to each other, similar to the two handles of scissors. Figure 1 There are two cross-arranged rods in the middle, and the U-shaped rod 221 is arranged between the two groups of support assemblies 21. The U-shaped rod 221 is rotatably connected to the bottom ends of the two support rods 211 located on one side of the two groups of support assemblies 21. The two support rods 211 arranged in the support assembly 21 of the device are hinged, and the height of the support cabin 11 can be adjusted by rotating the two support rods 211. Specifically, a limiting structure is arranged at the hinge point of the two groups of support assemblies 21, and the support cabin 11 can be limited after the height is adjusted.

[0053] like Figure 2As shown, this embodiment provides a specific method for rotatably connecting a U-shaped rod 221 with two support rods 211. Further, the rotatably connecting structure of the U-shaped rod 221 with the two support rods 211 includes: a second sleeve 212 and an elastic positioning pin 213. The two second sleeves 212 are respectively arranged at the bottom ends of the two support rods 211, the first sleeve 313 is located between the two second sleeves 212, the two second sleeves 212 are respectively sleeved on the U-shaped rod 221, and the second sleeve 212 is rotatably connected with the U-shaped rod 221, and the second sleeve 212 and the support rod 211 form an integral structure; the two elastic positioning pins 213 are respectively penetrated in the two second sleeves 212, one end of the elastic positioning pin 213 is located outside the second sleeve 212, and the other end of the elastic positioning pin 213 is located inside the second sleeve 212, and a plurality of positioning holes are opened in the circumference of the U-shaped rod 221, and one end of the elastic positioning pin 213 located in the second sleeve 212 is plugged into one of the positioning holes. The elastic locating pin 213 is an elastic and retractable locating pin. In this embodiment, the model of the elastic locating pin 213 can be M8*1.25-5. When in use, one end (pin head) of the elastic locating pin 213 is moved so that the end of the elastic locating pin 213 located in the second sleeve 212 is separated from the side wall of the U-shaped rod 221. At this time, the angle of the U-shaped rod 221 can be rotated to the desired angle, and then let go. Under the action of the elastic force, the elastic locating pin 213 positions the U-shaped rod 221.

[0054] Among them, other structures of this embodiment are consistent with those of embodiment 1, and are just optimizations made to embodiment 1.

[0055] Example 3

[0056] As a further improvement on Example 2, Figure 1 , 3As shown, further, the support cabin 11 includes: a support plate 111, a trolley case 112, a guide assembly, and a cover plate 115. A medical system is installed on the support plate 111. The medical system is used to provide emergency treatment to the wounded. The medical system includes a main control unit, a display unit, a communication unit, first aid equipment and a power supply unit. The power supply unit, the main control unit, and the first aid equipment are arranged on the support plate 111. The display unit and the communication unit are arranged on one side of the support plate 111. The main control unit is electrically connected to the display unit, the communication unit, the first aid equipment, the operation panel and the power supply unit. The power supply unit is used to supply power to other units and the first aid equipment. The first aid equipment is used to monitor the condition information of the wounded and provide first aid to the wounded. The communication unit is connected to the display unit signal for remote The display unit is used to display the information monitored by the emergency equipment and the video of the remote consultation. The emergency equipment includes life support equipment such as ventilators, ECG monitors, infusion pumps, syringe pumps, and negative pressure aspirators. The operating ends of these emergency equipment are located on one side of the support plate 111. There is also a pop-up button. When used, the display screen can be popped out to monitor the condition of the injured, conduct remote consultation (displayed on the display screen), etc. The information of all medical emergency equipment can be integrated into the central control tablet through wireless or data cable connection. There are a total of 3 central control tablets, one of which is used for display. One is used to display the information of the monitor and the infusion pump, the other is used to display the relevant information of the ventilator, and the other is used for remote consultation (mainly through 5G signals to realize remote video consultation and medical guidance). Emergency treatment can be carried out. The support cabin 11 and the medical system arranged thereon are the bearing unit 1. The support rod 211 is arranged at the bottom of the support plate 111; two symmetrically arranged trolley cases 112 are respectively mounted on the two ends of the support plate 111, and the height of the plane where the top surface of the support plate 111 is located is lower than the height of the plane where the top surfaces of the two trolley cases 112 are located. When the two trolley cases 112 are closed, the support plate 111 and the medical system arranged thereon can be The two guide assemblies are symmetrically arranged between the two trolley cases 112 and the support plate 111. The guide assemblies are used to guide the trolley cases 112 to move relative to the support plate 111. The two trolley cases 112 move away from each other, so that the medical system on the side of the support plate 111 can be leaked out to treat the wounded. The two trolley cases 112 move relative to each other to store the medical system. The two cover plates 115 are respectively arranged at opposite ends of the two trolley cases 112. The cover plates 115 are rotatably connected to the trolley cases 112 through the second hinge 117. The cover plates 115 are used to cover the support plate 111. When the device is in use, the guide assemblies are used to make the two trolley cases 112 move away from each other, so that the medical system on the side of the middle support plate 111 can be leaked out, and then the cover plates 115 are rotated so that the two cover plates 115 cover the top of the support plate 111. At this time, the wounded are placed on the entire support cabin 11.Among them, the second hinge 117 structure has a limiting function. When the rotating cover plate 115 and the top surface of the trolley case 112 are in the same plane, they cannot be rotated, so that the top surfaces of the two trolley cases 112 and the top surfaces of the cover plate 115 are in the same plane, which is convenient for the injured to lie on top.

[0057] This embodiment provides a specific structure of a guide assembly. Furthermore, the guide assembly includes: a guide shaft 113 and a sleeve. The axial direction of the guide shaft 113 is parallel to the length direction of the support plate 111. The two ends of the guide shaft 113 are fixed to the side walls of the support plate 111 through connectors, so that the guide shaft 113 is suspended on one side of the support plate 111 to avoid affecting the movement of the trolley case 112; two sleeves are respectively mounted on the circumference of the guide shaft 113, and the two sleeves are respectively arranged on the two trolley cases 112. When in use, by pushing the two trolley cases 112 to move, the two sleeves can slide on the guide shaft 113 to guide the trolley cases 112. Among them, the number of guide shafts 113 and sleeves can be set according to actual design needs.

[0058] like Figure 5As shown, further, the bottoms of the two trolley cases 112 are open, and the height of the plane where the bottom of the trolley cases 112 is located is lower than the height of the plane where the bottom of the support plate 111 is located, and the bottoms of the two trolley cases 112 and the bottom of the support plate 111 form a groove. Because the two support rods 211 can rotate relative to each other, the height can be adjusted, and at the same time, an electric drive structure is set at the bottom of the support plate 111, including a rectangular frame and a power mechanism. The rectangular frame is fixed to the bottom of the support plate 111; the power mechanism is set between the rectangular frame and the support rod 211, and the power mechanism includes a stepping motor, a screw, a screw nut, and a moving frame. Connecting rods are provided on both sides of the base of the stepper motor. The ends of the two connecting rods facing away from the base are connected to the support rod 211. One end of the screw rod is connected to the output end of the stepper motor. The stepper motor is used to drive the screw rod to rotate. The screw rod is fitted with a screw nut and threadedly connected. When the stepper motor drives the screw rod to rotate, the screw nut can move up and down on the screw rod. There are two moving frames, which are symmetrically arranged on the rectangular frame, and the moving frames are provided with sliding grooves along the length direction of the moving frames. The two ends of the screw nut are slidably connected in the sliding grooves of the two moving frames. In summary, when the stepper motor is working, it drives the screw rod to rotate, so that the screw nut moves up and down on the screw rod. At the same time, because the screw nut is slidably connected in the sliding grooves of the two moving frames, the screw nut will slide in the sliding grooves of the moving frames while moving on the screw rod, so that the screw rod moves up and down, driving the hinge points of the two support rods 211 in the two groups of support assemblies 21 to rotate relative to each other, realizing lifting and lowering, thereby facilitating the lifting and lowering of the support rods 211 driven by electricity. Among them, the two support rods 211 in each support assembly 21 are connected with the latch through the slide rail to form a movable X-shaped cross arm support structure. When the screw moves downward, the screw nut moves to the right in the slide slot, driving the two support rods 211 to unfold. When the screw moves upward, the screw nut moves to the left in the slide slot. A limit switch is provided at the leftmost end of the slide slot. When the screw nut reaches the limit switch, it drives the two support rods 211 to be folded in the groove. The electric drive structure in this embodiment can realize the function of automatic lifting, so that the two groups of support assemblies 21 can be stored in the groove, and then connected to the aircraft floor rail, which is more stable and avoids secondary injury to the injured. In addition, the roller 222 is connected to the U-shaped rod 221 through the L-shaped rod, and a side-flipping stop knob and an Alai tooth are also provided. The angle of the roller 222 in the horizontal direction and the vertical direction can be adjusted comprehensively, so that the entire wheel frame unit 2 can be stored in the groove while the two groups of support assemblies 21 are stored in the groove. In addition, the Allegheny gear can also achieve fine-leveling of the four rollers 222 in the wheel carrier unit 2.

[0063] The advantage of the present invention is that the device can realize rapid transportation on the aircraft and on the ground. Specifically, when the wounded is placed on the support cabin, the wheel frame unit arranged at the bottom of the support cabin can move the entire bearing unit, so as to facilitate the movement of the wounded on the ground. When the wounded is placed on the civil aircraft, the U-shaped rod is first rotated so that the rollers at both ends of the U-shaped rod are separated from the aircraft floor, and the bearing unit is supported by the U-shaped rod, and then the fixed plate is rotated so that the fixed plate is in contact with the aircraft floor. At this time, the entire bottom surface of the fixed plate is parallel to and in contact with the aircraft floor, and there is no tilt. Then, the fixed plate is connected and fixed to the aircraft floor guide rail through the locking structure, so as to complete the stable connection on the civil aircraft. When the wounded is transferred to the hospital after getting off the aircraft, the locking structure can be released, and the fixed plate and rollers can be rotated in the opposite direction so that the rollers at both ends of the U-shaped rod are in contact with the aircraft floor again, so as to achieve the purpose of ground transportation again. The device can be used in civil aircraft and ground transportation vehicles to realize rapid air-ground transport.
