When the condition requires, it is convenient for patients and injured people to lie down, allowing staff to move the patient to the ambulance via a stretcher.

[0003] Patent application number CN201510401145.7 relates to a stretcher, comprising: a bed surface, the bed surface including a pressure-bearing surface and a connecting sleeve, wherein the same-direction side edges of the pressure-bearing surface are respectively connected to one connecting sleeve; a pipe fitting, the pipe fitting passing through the connecting sleeve and detachably connected to the bed surface, the end face of the pipe fitting being an arc-shaped end face; and a fixing device, the fixing device being provided at the end of the connecting sleeve, the fixing device being used to fix the connecting sleeve to the pipe fitting. The stretcher structure of this patent is reliable and can ensure that the patient can be smoothly transported to a stretcher during lifting and then moved from the stretcher to a recuperation bed, thereby ensuring the safety of the patient after surgery and reducing the pain of postoperative transportation for the patient. The bed surface can then be pulled out from under the bed sheet or mattress without moving the patient. The stretcher is easy to use and low in cost. However, this device is difficult to adjust the stretcher, so it is very inconvenient when rescuing patients of different body sizes, and it is easy to increase the discomfort of the patient on the stretcher. Therefore, it is very necessary to design an adjustable critical care rescue stretcher that is highly practical and adjustable. Summary of the Invention

When the stretcher is in use, the rotating drum 9 is rotated, and the rotating drum 9 will drive the bidirectional screw 10 to rotate. When the screw rod 10 is rotated, the bidirectional screw rod 10 will drive the two frames 1 to gather or separate through two opposite threads. When the frame 1 separates, it will drive the mounting block 6 to move together, and the mounting block 6 will drive the mounting rod 7 to move, so that the fabric 8 wrapped around the mounting rod 7 is stretched, and then drive the mounting rod 7 to rotate on the mounting block 6. After the rotation adjustment, the pin 32 is inserted into the mounting block 6 and the mounting rod 7 is limited, thereby realizing the adjustment of the width of the frame 1, so that it is suitable for patients of different body shapes, thereby improving the applicability of the device; the surface of the rotating rod 31 is rotatably connected to the inner wall of the frame 1, the surface of the fabric 8 is fixedly connected to the surface of the mounting rod 7, the two ends of the rotating drum 9 are in contact with the surface of the frame 1, and a plurality of through holes are opened on the surface of the mounting rod 7, and the inner wall of the through hole is slidably connected to the surface of the pin 32.

[0016] The rotating device 3 also includes a telescopic plate 33, a support plate 34, a threaded rod 35, a moving rod 36 and a fixed plate 37. The telescopic plate 33 is fixedly connected to the bottom of the frame 1, the support plate 34 is fixedly connected to the side of the frame 1 close to the mounting block 6, the threaded rod 35 is arranged on the inner wall of the telescopic plate 33, the moving rod 36 is slidably connected to the inner wall of the mounting rod 7, and the fixed plate 37 is fixedly connected to the side of the mounting rod 7 away from the mounting block 6. When the medical staff carries the stretcher on the stairs, the patient will be on the fabric 8 and drive the mounting block 6 to rotate. The mounting block 6 will rotate in the frame 1 through the rotating rod 31, thereby ensuring that the patient is as level as possible, preventing the patient and the stretcher from tilting together, which is prone to the risk of slipping. At the same time, when the mounting block 6 drives the mounting rod 7 to rotate When the staircase is moved, the movable rod 36 in the mounting rod 7 will slide down under the action of gravity, and the movable rod 36 will drive the fixed plate 37 to fall on the support plate 34, so that the support plate 34 limits it to prevent it from rotating too much, thereby causing the fabric 8 to contact the stairs and affect normal use. At the same time, the telescopic plate 33 can be driven to retract by rotating the threaded rod 35, thereby reducing the gathering between the fixed plate 37 and the support plate 34, thereby adjusting the moving distance of the fixed plate 37 and improving applicability; the telescopic plate 33 is composed of two connecting plates that slide against each other, the upper connecting plate is threadedly connected to the threaded rod 35, and the lower connecting plate is rotatably connected to the threaded rod 35, and a spring is provided between the end of the movable rod 36 away from the fixed plate 37 and the inner wall of the mounting rod 7; Working principle: when the stretcher is in use, the rotating drum 9 is rotated, and the rotating drum 9 will drive the bidirectional screw 10 to rotate.

The mounting block 6 will rotate in the frame 1 through the rotating rod 31, thereby ensuring that the patient is as level as possible and preventing the patient and the stretcher from tilting together, which may easily cause the risk of slipping. At the same time, when the mounting block 6 drives the mounting rod 7 to rotate, the moving rod 36 in the mounting rod 7 will slide down under the action of gravity. The moving rod 36 will drive the fixed plate 37 to fall on the support plate 34, so that the support plate 34 limits it to prevent it from rotating too much, thereby causing the fabric 8 to contact the stairs and affecting normal use.

The mounting sleeve 51 is sleeved on the surface of the handle 2, and the strap 52 is fixedly connected to the surface of the mounting sleeve 51. When transporting a patient with a heavier weight, the mounting sleeve 51 is mounted on the handle 2 and the strap 52 is placed on the shoulder, thereby reducing the effort of lifting the stretcher during transportation, thereby saving more effort. At the same time, when not in use, the mounting sleeve 51 is removed from the handle 2, and the mounting sleeve 51 is rolled up and placed on the mounting post 54 in the mounting groove 53, so that the mounting sleeve 51 and the strap 52 on its surface can be stored when not in use; the supporting device 5 also includes a mounting groove 53 and a mounting post 54. The mounting groove 53 is opened on the surface of the frame 1, and the mounting post 54 is fixedly connected to the inner wall of the mounting groove 53; Working principle: when the mounting block 6 drives the rotating rod 31 to rotate, the rotating rod 31 will simultaneously drive the rotating plate 41 to rotate, and the rotating plate 41 rotates and drives the limiting rod 43 in the arc groove 42 to move. The limiting rod 43 will compress the elastic part in the arc groove 42, so that the rotating rod 31 will encounter resistance during the rotation process, causing the stretcher to rotate slowly during the rotation process, preventing the stretcher from rotating rapidly and causing the patient on it to slide and then fall off the stretcher, thereby improving the safety of the stretcher.

[0020] When transporting a heavier patient, the mounting sleeve 51 is mounted on the handle 2 and the strap 52 is placed on the shoulder, thereby reducing the effort required to lift the stretcher during transport, thereby saving more effort. When not in use, the mounting sleeve 51 is removed from the handle 2, rolled up and placed on the mounting post 54 in the mounting groove 53, so that the mounting sleeve 51 and the strap 52 on its surface can be stored when not in use.
