Therefore, it should not be understood as limiting the scope of protection of this application.

[0022] In response to the drawback of the existing technology, which makes it difficult to carry, the inventors conducted a careful analysis and found that the main reason for the above problem of existing stretchers is that the stretchers are too long and cannot be folded to shorten the length when carried. Based on this analysis, the inventors have made structural improvements to the stretcher.

[0023] like Figure 1-4 As shown, a multifunctional stretcher in the present application includes a bracket 1, a pad 2, a restraint component 3, support legs 4 and a player 5.

[0024] refer to Figure 1-3The bracket 1 includes a fixed frame 11, a movable frame 12, a connecting piece 13 and a limiting screw sleeve 14. The movable frame 12 is respectively provided at both ends of the fixed frame 11, and the end adjacent to the fixed frame 11 can be movably connected to the fixed frame 11 through the connecting piece 13. The fixed frame 11, the movable frame 12 and the connecting piece 13 at the movable connection are all provided with threads. The limiting screw sleeve 14 can be threadedly connected to the fixed frame 11, the movable frame 12 and the connecting piece 13 at the same time, or can be threadedly connected to the fixed frame 11 only after rotating to one end, so that the movable frame 12 can be coaxially fixed with the fixed frame 11 or folded onto the fixed frame 11 after flipping.

[0025] Specifically, a connecting groove 15 is provided at one adjacent end of the fixed frame 11 and the movable frame 12 , and connecting blocks 16 matching the connecting groove 15 are provided at both ends of the connecting member 13 . The connecting blocks 16 can be inserted into the connecting groove 15 and hinged to the connecting groove 15 .

[0026] Thus, when in use, the limiting screw sleeve 14 can be threadedly connected to the fixed frame 11, the movable frame 12 and the connecting piece 13 at the same time, so that the fixed frame 11 and the movable frame 12 can be relatively fixed, so that the stretcher can be used normally; when carrying it outside, the limiting screw sleeve 14 can be rotated to one end so that the limiting screw sleeve 14 is only threadedly connected to the fixed frame 11. At this time, the movable frame 12 can be flipped over and folded onto the fixed frame 11, thereby shortening the length of the stretcher, making it convenient to place the stretcher in an emergency vehicle, or to facilitate medical staff to carry the stretcher themselves and walk to the patient when the emergency vehicle cannot reach the patient.

[0027] Furthermore, both the fixed frame 11 and the movable frame 12 are provided with a crossbar 17, which can be used to increase the stability and load-bearing capacity of the fixed frame 11 and the movable frame 12. In addition, in order to reduce the weight of the stretcher and facilitate portability, the bracket 1 is made of hollow aluminum alloy, which can reduce the weight of the stretcher as much as possible while ensuring sufficient rigidity.

[0028] The pad 2 is arranged on the bracket 1. Specifically, the pad 2 is divided into three parts according to the structure of the bracket 1, and connecting ears are provided at both ends of the pad 2. It is set on the bracket 1 through the connecting ears. In order to prevent the pad 2 and the bracket 1 from moving relative to each other, anti-slip pads are provided in the connecting ears, and a fixing groove is also provided at the lower end of the pad 2, and the cross bar 17 can be just stuck in the fixing groove.

[0029] refer to Figure 1 4 , the restraint assembly 3 is used to restrain the patient, and the restraint assembly 3 includes a head restraint belt 31 , a torso restraint belt 32 and a limb restraint belt 33 .

[0030] The head restraint 31 can be used to restrain the patient's head. One end of the head restraint 31 is fixedly connected to the backing plate 2, and the other end is detachably connected to each other via Velcro. The limb restraint 33 can be used to restrain the patient's torso. The two ends of the torso restraint 32 are respectively connected to the two ends of the support 1. The limb restraint 33 can be used to restrain the patient's limbs. One end of the limb restraint 33 is detachably connected to the support 1, and the other end is used to restrain and fix the patient's limbs. The torso restraint 32 and limb restraint 33 are detachably connected to the support 1, and their positions can be adjusted according to the patient's body shape.

[0031] Furthermore, the limb restraint belt 33 includes a fixing belt 331 and a connecting belt 332 . The two ends of the fixing belt 331 are detachably connected to each other through Velcro. One end of the connecting belt 332 is fixedly connected to the fixing belt 331 , and the other end is detachably connected to the bracket 1 .

[0032] Furthermore, buckles 333 for strengthening fixation are provided at both ends of the fixing belt 331 , and one end of the buckle 333 is connected to the fixing belt 331 through an auxiliary belt 334 .

[0033] The Velcro strips at both ends of the strap 331 allow for quick restraint of the patient's limbs. Buckles 333, located at both ends of the strap 331, reinforce the restraint and prevent the patient from breaking free. Furthermore, the buckles 333 and auxiliary connecting straps 332 are located outside the strap 331. When the buckles 333 are used to reinforce the restraint, the strap 331 can be placed between the patient's limbs and the buckles 333, preventing the hard buckles 333 from causing discomfort or even pressure injuries.

[0034] refer to Figure 1-3 The support leg 4 is provided at the lower end of the bracket 1, one end of the support leg 4 is connected to the bracket 1, and the other end is provided with a universal wheel 41. The support leg 4 can make the stretcher capable of being carried by two people or dragged by one person using the universal wheel 41, adapting to the needs of different terrains and patient postures.

[0035] Specifically, a connecting groove 15 is provided at one end of the support leg 4 connected to the bracket 1, a boss 121 is provided on the movable frame 12, and a connecting block 16 matching the connecting groove 15 is provided on the boss 121. The connecting block 16 can be inserted into the connecting groove 15 and hinged to the connecting groove 15, so that the support leg 4 can be set vertically with the movable frame 12, or folded on the movable frame 12 after being flipped over, and a fixing bolt 42 is also provided at the connecting end of the support leg 4 and the boss 121. When the support leg 4 is set vertically with the movable frame 12, the fixing bolt 42 can be screwed to the support leg 4 and the boss 121 at the same time.

[0036] Therefore, when in use, the fixing bolts 42 can be screwed together with the support legs 4 and the bosses 121 at the same time, so that the support legs 4 and the movable frame 12 can be kept vertically arranged; or when carrying it outside, the fixing bolts 42 can be unscrewed and screwed together with only the support legs 4. At this time, the support legs 4 can be flipped over and folded onto the movable frame 12, thereby reducing the volume of the stretcher and making it easier to carry.

[0037] Furthermore, the support leg 4 includes a support sleeve 43 and a screw 44. One end of the support sleeve 43 is movably connected to the boss 121. One end of the screw 44 is inserted into and screwed to the support sleeve 43. The other end of the screw 44 is fixedly provided with an adjustment nut 45. By inserting one end of the screw 44 into the support sleeve 43 and screwing it to the support sleeve 43, the height of the support leg 4 can be adjusted as needed.

[0038] The player 5 is detachably mounted on the crossbar 17 of the movable frame 12 at one end, and can be used to play soothing music or psychological comforting words during rescue, which can relieve the patient's tension to a certain extent and help stabilize the patient's emotions.

[0039] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the above-described specific embodiments under the concept of the present invention should be within the scope of protection of the present invention.
