Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to an emergency transport stretcher. Background Technology

[0002] Emergency transport stretchers are mobile medical devices specifically designed for the safe and rapid transfer of patients in emergency medical scenarios. Their core function is to provide a stable support platform for patients during pre-hospital emergency care, in-hospital transport, or disaster relief, ensuring they are protected from secondary injuries during movement, while also facilitating operation by medical staff.

[0003] Currently, the outriggers used to connect the casters to the bottom of emergency transport stretchers mostly use a rotating folding method when folding them up. During the rotation and folding process, staff members located in the direction of the outriggers' rotation are easily pinched and injured, posing a certain safety hazard. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an emergency transport stretcher to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an emergency transport stretcher, comprising a base, a driving component and a limiting component respectively disposed inside the base, a sliding component disposed on the top of the base, a support frame disposed on the top of the sliding component, and an anti-fall component disposed on the outer surface of the support frame. The driving component is used to drive the limiting component to move, the limiting component is used to limit and fix the sliding component, the sliding component is used to adjust the height of the support frame, and the anti-fall component is used to prevent items or patients above the support frame from falling.

[0007] Furthermore, the drive assembly includes a pedal, a connecting rod is fixedly connected to the bottom of the pedal, a cross plate is fixedly connected to the bottom of the connecting rod, a sliding groove is provided inside the base, the connecting rod and the cross plate are slidably connected inside the sliding groove, a first spring is fixedly connected inside the sliding groove, and the first spring is fixedly connected to the cross plate.

[0008] Furthermore, the limiting component includes a limiting rod, a second spring is fixedly connected to the outer surface of the limiting rod, the second spring is fixedly connected to the inside of the slide groove, the limiting rod is slidably connected to the inside of the slide groove, a pin is rotatably connected to the outer surface of the limiting rod, and a pulley is rotatably connected to the outer surface of the pin.

[0009] Furthermore, the sliding assembly includes a connecting plate, the outer surface of which is threaded with a fixing bolt, the connecting plate being fixedly installed on the top of the base by the fixing bolt, the outer surface of which is fixedly connected with a fixing column, the top of which is fixedly connected with a square plate, the outer surface of which is slidably connected with a sliding column, and both the outer surfaces of the fixing column and the sliding column having limit grooves, the limit rod being located inside the fixing column.

[0012] Furthermore, a groove is provided on the top of the pedal.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects a drive component and a sliding component. The drive component is located between the support frame and the base. When the drive component is stepped on and moves downward, it comes into contact with the limiting component, squeezing and pushing the limiting component to slide within the base and the sliding component. When the limiting component separates from the sliding component, the limiting and fixing of the sliding component is released. At this time, the support frame can be pushed to move closer to the base, achieving folding and storage.

[0015] 2. This utility model uses the connection between the rotating sleeve and the knob bolt. The knob bolt fixes the rotating sleeve and the barrier frame. When the barrier frame is erected above the support frame, it can prevent the patient on the support frame from falling. Rotating the knob bolt releases the limiting fixation on the rotating sleeve, pushing the barrier frame to drive the rotating sleeve to rotate on the support frame, so that the barrier frame hangs down below the support frame. At this time, it is convenient to transfer the patient on the support frame to the hospital bed, avoiding the barrier frame from obstructing the patient transfer.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is an emergency transport stretcher, including a base 1. The base 1 is internally provided with a drive component 2 and a limiting component 3. The top of the base 1 is provided with a sliding component 4. The top of the sliding component 4 is provided with a support frame 5. The outer surface of the support frame 5 is provided with an anti-fall component 6. The drive component 2 is used to drive the limiting component 3 to move. The limiting component 3 is used to limit and fix the sliding component 4. The sliding component 4 is used to adjust the height of the support frame 5. The anti-fall component 6 is used to prevent items or patients above the support frame 5 from falling.

[0029] Pushing the support frame 5 moves the base 1 and the casters to an open area. Then, step on the drive component 2 on the base 1. The drive component 2 pushes the limiting component 3 to move. The limiting component 3 slides between the base 1 and the sliding component 4, causing the limiting component 3 to separate from the sliding component 4, thereby releasing the limiting fixation of the sliding component 4. At this time, lifting the support frame 5 can move the support frame 5 away from the base 1, thereby adjusting the height of the support frame 5.

[0030] This invention connects the driving component 2 and the sliding component 4. The driving component 2 is located between the support frame 5 and the base 1. When the driving component 2 is stepped on and moves downward, it comes into contact with the limiting component 3, squeezing and pushing the limiting component 3 to slide within the base 1 and the sliding component 4. When the limiting component 3 separates from the sliding component 4, the limiting and fixing of the sliding component 4 is released. At this time, the support frame 5 can be pushed to move closer to the base 1, realizing folding and storage. The distance between the support frame 5 and the base 1 is limited by the sliding component 4, thus leaving room for the staff to move and avoiding injury to the staff.

[0031] In one embodiment, the drive assembly 2 includes a pedal 201, a connecting rod 202 fixedly connected to the bottom of the pedal 201, a cross plate 203 fixedly connected to the bottom of the connecting rod 202, a sliding groove 204 provided inside the base 1, the connecting rod 202 and the cross plate 203 being slidably connected inside the sliding groove 204, and a first spring 205 fixedly connected inside the sliding groove 204, the first spring 205 being fixedly connected to the cross plate 203.

[0032] When the pedal 201 is pressed, the pedal 201 moves the connecting rod 202, causing the connecting rod 202 to retract into the slide groove 204 in the base 1. At the same time, the connecting rod 202 moves the horizontal plate 203 downward, and the horizontal plate 203 compresses the first spring 205. When the pedal 201 is released, the first spring 205 pushes the horizontal plate 203, the connecting rod 202 and the pedal 201 to reset.

[0033] In one embodiment, the limiting component 3 includes a limiting rod 301, a second spring 302 fixedly connected to the outer surface of the limiting rod 301, the second spring 302 fixedly connected to the inside of the slide groove 204, the limiting rod 301 slidably connected to the inside of the slide groove 204, a pin 303 rotatably connected to the outer surface of the limiting rod 301, and a pulley 304 rotatably connected to the outer surface of the pin 303.

[0034] When the horizontal plate 203 moves downward, it contacts the pulley 304. The horizontal plate 203 squeezes and pushes the pulley 304 to move. The pulley 304 drives the limiting rod 301 to slide through the pin 303. The limiting rod 301 compresses the second spring 302. When the horizontal plate 203 returns to its original position, the second spring 302 can push the limiting rod 301 to return to its original position. The pulley 304 is located between the horizontal plate 203 and the limiting rod 301, which reduces friction.

[0035] In one embodiment, the sliding assembly 4 includes a connecting plate 401, with a fixing bolt 402 threadedly connected to the outer surface of the connecting plate 401. The connecting plate 401 is fixedly installed on the top of the base 1 by the fixing bolt 402. A fixing post 403 is fixedly connected to the outer surface of the connecting plate 401. A square plate 404 is fixedly connected to the top of the fixing post 403. A sliding post 405 is slidably connected to the outer surface of the fixing post 403. Limiting grooves 406 are formed on the outer surfaces of both the fixing post 403 and the sliding post 405. The limiting rod 301 is located inside the fixing post 403.

[0036] The upper end of the sliding column 405 is fixedly installed at the bottom of the support frame 5 by another set of connecting plates 401 and fixing bolts 402. The limiting rod 301 slides in the fixed column 403 and separates from the limiting groove 406. At this time, the limiting fixation between the fixed column 403 and the sliding column 405 can be released. The support frame 5 is lifted to drive the sliding column 405. The sliding column 405 can move up and down along the fixed column 403. The square plate 404 limits the movement distance of the sliding column 405 to prevent the sliding column 405 from separating from the fixed column 403. After adjusting the height of the support frame 5, the horizontal plate 203 and the limiting rod 301 are released. The limiting rod resets and passes through the limiting grooves 406 on the fixed column 403 and the sliding column 405 respectively, completing the limiting fixation of the fixed column 403 and the sliding column 405 and preventing unnecessary movement of the sliding column 405.

[0037] In one embodiment, the anti-fall component 6 includes a rotating sleeve 601, which is rotatably connected to the support frame 5. A barrier frame 602 is fixedly connected to the outer surface of the rotating sleeve 601, and a knob bolt 603 is threadedly connected to the outer surface of the rotating sleeve 601.

[0038] Rotate the knob bolt 603 to separate the end of the knob bolt 603 from the support frame 5, thereby releasing the limiting fixation between the rotating sleeve 601 and the support frame 5. At this time, the barrier frame 602 and the rotating sleeve 601 can be pushed to rotate.

[0039] In one embodiment, for the support frame 5, a soft pad 7 is placed on the top of the support frame 5, and a handle 8 is fixedly connected to the outer surface of the support frame 5.

[0040] The cushion 7 provides protection for the patient, making the patient more comfortable when lying on the support frame 5, and the handle 8 makes it easier for medical staff to lift the support frame 5.

[0041] In one embodiment, the pedal 201 described above has a groove 9 on its top.

[0042] The groove 9 makes the surface of the pedal 201 uneven, thereby increasing the friction.

[0043] Through the above technical solution, 1. By connecting the driving component 2 and the sliding component 4, the driving component 2 is located between the support frame 5 and the base 1. When the driving component 2 is stepped on and moves downward, it contacts the limiting component 3, squeezing and pushing the limiting component 3 to slide within the base 1 and the sliding component 4. When the limiting component 3 separates from the sliding component 4, the limiting and fixing of the sliding component 4 is released. At this time, the support frame 5 can be pushed to move closer to the base 1, realizing folding and storage. The distance between the support frame 5 and the base 1 is limited by the sliding component 4, thus leaving room for the staff to move and avoiding injury to the staff; 2. The rotating sleeve 601 is connected to the knob bolt 603, which fixes the rotating sleeve 601 and the barrier frame 602. When the barrier frame 602 is erected above the support frame 5, it can prevent the patient on the support frame 5 from falling. Rotating the knob bolt 603 releases the limiting fixation on the rotating sleeve 601, pushing the barrier frame 602 to drive the rotating sleeve 601 to rotate on the support frame 5, so that the barrier frame 602 hangs down below the support frame 5. At this time, it is convenient to transfer the patient on the support frame 5 to the hospital bed, and the barrier frame 602 avoids obstructing the patient transfer.
