Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretcher technology, specifically to a stretcher device for transferring critically ill patients. Background Technology
[0002] In pre-hospital emergency care, in-hospital transport, and at the scene of public health emergencies, the rapid and safe transport of critically ill patients is one of the key links to successful rescue. At present, the commonly used transport tools in clinical practice are still mainly traditional folding stretchers, scoop stretchers, or simple wheeled flatcars.
[0003] Traditional stretchers only have two independent functions: "lifting" or "pushing". They cannot switch between lifting and pushing instantly on the same device according to the available space or manpower. This makes it difficult to operate in narrow corridors, elevators or ambulance compartments, delaying rescue opportunities. In addition, the fixed handles on the stretcher take up extra space in the ambulance or helicopter cabin, affecting the operation of medical staff.
[0004] Therefore, a stretcher device for transferring critically ill patients is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a stretcher device for transferring critically ill patients in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A stretcher device for transferring critically ill patients includes a stretcher body. Two sets of support frames are fixedly installed on the bottom surface of the stretcher body, and support legs are rotatably sleeved on the surface of the support frames. Locking components are provided on the surfaces of the support frames and support legs for locking and limiting the support legs when they are unfolded and folded. Opening and closing components are provided on the two sets of support frames, and stretcher handles are fixedly installed on the movable parts of the opening and closing components. The stretcher handles are movably inserted into the support frames, and the opening and closing components drive the stretcher handles to unfold and retract to lift the stretcher body.
[0007] Furthermore, the stretcher body includes a frame, the surface of which is covered with several sets of support cloths, and the surface of which is fixedly covered with two sets of anti-slip sleeves. The top surface of the frame is fixedly installed with multiple sets of straps and a U-shaped wrapping frame, and the straps are matched with the U-shaped wrapping frame via Velcro on their surface for fixing the patient.
[0008] Furthermore, the locking assembly includes a side plate fixedly installed on the surface of the support frame, and the surface of the side plate is provided with two sets of first through holes, and the surface of the support leg is provided with a second through hole. A pin is inserted into the second through hole and one of the first through holes for fixing the support leg.
[0009] Furthermore, the bottom end of the support leg is provided with rollers / universal wheels / self-locking universal wheels.
[0010] Furthermore, the opening and closing assembly includes a rotating shaft that is rotatably inserted into two sets of support frames. The surface of the rotating shaft is symmetrically provided with two sets of threads, and the two sets of threads are arranged in opposite directions. The rotating shaft and the surface of the threads are threadedly fitted with a movable frame. The stretcher handle is fixedly installed on the end face of the movable frame, and the stretcher handle is movably inserted into the support frame.
[0011] Furthermore, the surface of the stretcher handle is fixedly fitted with a rubber anti-slip sleeve.
[0012] The beneficial effects of this utility model are as follows: The stretcher body is the main load-bearing structure, with two sets of support frames symmetrically installed on both sides of its bottom surface. The support legs, which are hinged on the support frames, can switch between unfolded and folded states. The support legs are locked in the unfolded or folded position by a locking component via a pin to prevent accidental folding. The opening and closing component uses a screw or slider mechanism to drive the movable stretcher handle to extend or retract along the support frame. When the stretcher handle is unfolded, it extends to facilitate carrying by two people. When the stretcher handle is folded, it retracts to reduce the storage volume and meet the needs of rapid conversion in emergency scenarios. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0018] like Figures 1 to 4 As shown, a stretcher device for transferring critically ill patients includes a stretcher body 1; as Figure 1 and Figure 2 As shown, specifically, the stretcher body 1 includes a frame 101, the surface of the frame 101 is covered with several sets of support cloths 102, the surface of the frame 101 is fixedly covered with two sets of anti-slip sleeves 103, and the top surface of the frame 101 is fixedly installed with multiple sets of straps 104 and U-shaped wrapping frames 105. The straps 104 are matched with the U-shaped wrapping frames 105 through Velcro on their surface for fixing the patient.
[0019] More specifically, the frame 101 is a lightweight alloy rectangular frame, and the surface is covered with a support cloth 102 for supporting the patient. It is wrapped around the patient by straps 104 and U-shaped wrapping frame 105, and forms a multi-point fixation system with Velcro to achieve rapid restraint of the chest, abdomen and knees.
[0020] Two sets of support frames 2 are fixedly installed on the bottom surface of the stretcher body 1, and support legs 3 are rotatably sleeved on the surface of the support frames 2. Locking components 4 are provided on the surfaces of the support frames 2 and the support legs 3 to lock and limit the support legs 3 when they are unfolded and folded. Figure 2 , Figure 3 and Figure 4As shown, specifically, the locking component 4 includes a side plate 401 fixedly installed on the surface of the support frame 2, and the surface of the side plate 401 is provided with two sets of first through holes 402, and the surface of the support leg 3 is provided with a second through hole 403. A pin 404 is inserted into the second through hole 403 and one of the first through holes 402 for fixing the support leg 3.
[0021] More specifically, when the support leg 3 is unfolded into a vertical state, the second through hole 403 on the surface of the support leg 3 corresponds to the first through hole 402 on the side plate 401 located below, and is inserted into the pin 404 to achieve vertical locking of the support leg 3. When the support leg 3 is folded, the second through hole 403 on the surface of the support leg 3 corresponds to the first through hole 402 on the side plate 401 located above, and is inserted into the pin to achieve locking of the support leg 3 after folding.
[0022] Two sets of support frames 2 are equipped with opening and closing components 5, and stretcher handles 6 are fixedly installed on the movable parts of the opening and closing components 5. The stretcher handles 6 are movably inserted into the support frames 2, and the opening and closing components 5 drive the stretcher handles 6 to unfold and retract to lift the stretcher body 1; Figure 2 As shown, specifically, the opening and closing assembly 5 includes a rotating shaft 501 that is rotatably inserted into two sets of support frames 2. The surface of the rotating shaft 501 is symmetrically provided with two sets of threads 502, and the two sets of threads 502 are arranged in opposite directions. The rotating shaft 501 and the surface of the threads 502 are threadedly fitted with a movable frame 503. The stretcher handle 6 is fixedly installed on the end face of the movable frame 503, and the stretcher handle 6 is movably inserted into the support frame 2.
[0023] More specifically, the rotating shaft 501 has reverse threads 502 at both ends, forming a two-way screw mechanism. When the rotating shaft 501 is rotated, the movable frame 503 moves synchronously towards or away from each other along the direction of the thread 502. Moving outward causes the stretcher handle 6 to extend, making it easier to carry, while moving inward causes the stretcher handle 6 to retract, achieving folding.
[0024] like Figure 2 As shown, in some practical applications, the surface of the stretcher handle 6 is fixedly fitted with a rubber anti-slip sleeve.
[0025] More specifically, a rubber anti-slip sleeve is wrapped around the outer surface of the stretcher handle 6, which increases the contact area of the grip surface by utilizing the elastic deformation of the high-friction rubber.
[0026] In some practical applications, the bottom of the support leg 3 is equipped with rollers / universal wheels / self-locking universal wheels.
[0027] More specifically, the bottom of the support leg 3 integrates rollers / universal wheels / self-locking universal wheels. When unfolded, the rollers / universal wheels / self-locking universal wheels are in contact with the ground, allowing the stretcher to be pushed by one person, reducing physical exertion.
[0028] In summary: The stretcher body 1 is the main load-bearing structure, with two sets of support frames 2 symmetrically installed on both sides of its bottom surface. The support legs 3, which are hinged on the support frames 2, can switch between two states: extended for walking and folded close to the bottom surface of the stretcher. The support legs 3 are locked in the extended or folded position by the locking component 4 via a pin to prevent accidental folding. The opening and closing component 5 uses a screw or slider mechanism to drive the movable stretcher handle 6 to extend or retract along the support frame 2. When the stretcher handle 6 is extended, the handle extends to facilitate carrying by two people. When the stretcher handle 6 is folded, the handle retracts to reduce the storage volume and meet the needs of rapid conversion in emergency scenarios.
