Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretcher technology, and in particular to an assembled stretcher. Background Technology
[0002] Stretchers play an important role in emergency care and transportation. They are temporary devices used to move patients. The main function of a stretcher is to keep the patient's body stable and comfortable, reduce the occurrence of secondary injuries, and facilitate handling and transportation. Stretchers are suitable for various emergency medical situations, such as the scene of accidents such as earthquakes, traffic accidents, and fires, as well as hospital emergency rooms.
[0003] Existing modular stretchers typically involve covering two support frames with a support cloth, then rotating and connecting the two support frames to secure them in place. The stretcher is then placed on the ground via outriggers, and the patient is placed on the support cloth. Two people then simultaneously lift the two support frames to transport the patient.
[0004] However, because the surface of the support cloth is relatively smooth, and it is easy for people to shake or tilt when lifting the support frame, the patient may slip due to the shaking or tilting of the support frame, causing secondary injury to the patient. Utility Model Content
[0005] The technical problem this invention aims to solve is that, because the surface of the supporting cloth is relatively smooth and the support frame is prone to shaking or tilting when lifted by personnel, patients may slip due to the shaking or tilting of the support frame, causing secondary injuries to the patients.
[0006] The technical solution adopted by this utility model to solve its technical problem is: an assembled stretcher, including two support frames, which are interlocked with each other. A support cloth is fitted over the surface of each support frame. Support legs are provided at the bottom of each support frame. A reinforcing device is provided on one side of each support frame. An auxiliary device is provided on one side of one of the support frames. The reinforcing device includes a concave frame, which is fixedly connected to the support frame. Multiple circular holes are opened on one side of the concave frame. A circular shaft is provided inside the concave frame, and one end of the circular shaft is fixed... A connecting plate is connected, and a pin is fixedly connected to the side of the connecting plate near the round shaft. The size and shape of the pin's surface are adapted to the size and shape of the inner wall of the round hole. The surface of the connecting plate is larger than the inner wall of the concave frame. A strap is fixedly connected to one side of the round shaft, and a collar is fixedly connected to the end of the strap away from the round shaft. A support rod is fixedly connected to the side of the support frame away from the concave frame. A screw is fixedly connected to one side of the support rod. A threaded hole ring is threadedly connected to the surface of the screw. The collar is fitted onto the surface of the screw, and the surface of the threaded hole ring is larger than the inner wall of the collar.
[0007] The effect achieved by the above components is as follows: By setting up the reinforcement device, the patient is first placed on the support cloth. At this time, the collar is manually moved, causing the collar to move the strap. When the collar moves to the position where it is fitted onto the surface of the screw, the screw hole ring is manually rotated, causing the screw hole ring to move left and right along the surface of the screw. When the screw hole ring moves to the position where it compresses the collar surface, it reaches the limit of the collar, allowing the strap to cover the patient's body. At this time, the connecting plate is manually rotated, causing the connecting plate to drive the rotating shaft to rotate, causing the connecting plate to drive the round shaft to rotate along the inside of the concave frame. During the rotation of the round shaft, the strap is wound up, and the strap is tightened against the patient's body during the winding process. When the patient is securely fixed to the support frame, the pin is aligned with the inner wall of any circular hole. At this point, the connecting plate is manually pushed towards the concave frame, causing the connecting plate to move the pin towards the concave frame. This causes the connecting plate to slide the circular shaft along the inside of the concave frame. When the pin moves to the position inside the circular hole, it works with the connecting plate to fix the position of the circular shaft and the strap, thereby achieving auxiliary fixation of the patient. This reduces the risk of the patient slipping due to shaking or tilting of the support frame when personnel lift it, thus preventing secondary injuries. This improves the stability and safety of patient transport.
[0008] Preferably, the surface of the screw hole ring is fixedly connected with a plurality of anti-slip strips, and the plurality of anti-slip strips are arranged at equal intervals.
[0009] The effect achieved by the above components is that by setting anti-slip strips, the anti-slip strips can increase the friction between the hand and the surface of the screw hole ring, reducing the chance of the hand slipping when manually turning the screw hole ring.
[0010] Preferably, a reinforcing block is fixedly connected to one side of the support rod, and the reinforcing block is fixedly connected to the support frame.
[0011] The effect achieved by the above components is that by setting up the reinforcing block, the reinforcing block can provide auxiliary support and reinforcement to one side of the support rod, reducing the possibility of the support rod shaking or separating from the support frame during use.
[0012] Preferably, a handle is fixedly connected to one side of the connecting plate, and the inner side of the handle is provided with multiple anti-slip protrusions.
[0013] The effect achieved by the above components is that by setting a handle, the handle can provide a point of leverage for personnel, allowing personnel to easily rotate the connecting plate by manually turning the handle, and at the same time, the handle can be used to easily insert and remove the pin.
[0014] Preferably, a limiting plate is fixedly connected to the end of the circular shaft away from the connecting plate, and the surface of the limiting plate is larger than the inner wall of the concave frame.
[0015] The effect achieved by the above components is that by setting a limiting plate, the limiting plate can intercept the round shaft during the movement, reducing the possibility of the round shaft leaving the concave frame at the end away from the connecting plate during the movement.
[0016] Preferably, the auxiliary device includes a circular hole rod, which is fixedly connected to the support frame. A circular rod is slidably connected to the inner wall of the circular hole rod. A baffle is fixedly connected to one end of the circular rod. An auxiliary plate is fixedly connected to one side of the circular hole rod. A spring is fixedly connected to one side of the auxiliary plate. The other end of the spring is fixedly connected to the baffle. A circular block is fixedly connected to the end of the circular rod away from the baffle. The surface of the circular block is larger than the inner wall of the circular hole rod.
[0017] The effect achieved by the above-mentioned components is as follows: By setting up the auxiliary device, when the patient lies flat on the support cloth, the spring's reaction force causes the spring to pull the baffle to move and fit against the patient's feet. When the patient accidentally slides into the gap of the support frame, the patient's feet push the baffle, causing the baffle to move away from the round hole rod. This causes the baffle to drive the round rod and round block to move. When the round block moves to the position where it fits against the surface of the round hole rod, it limits the round rod and the baffle, allowing the baffle to intercept the patient's feet, thus preventing the patient from slipping. This reduces the possibility of the patient slipping when the support frame tilts significantly, further improving the patient's restraint effect.
[0018] Preferably, a plurality of reinforcing ribs are fixedly connected to one side of the baffle, and the plurality of reinforcing ribs are arranged at equal intervals.
[0019] The effect achieved by the above components is that by setting reinforcing ribs, the strength of the baffle can be increased, and the deformation of the baffle under stress during use can be reduced.
[0020] Preferably, a rubber pad is fixedly connected to the side of the baffle away from the reinforcing rib, and the surface of the rubber pad is provided with multiple rubber protrusions.
[0021] The effect achieved by the above components is that by setting up rubber pads, the rubber pads can increase the fit between the sole of the foot and the baffle, while increasing the friction between the patient's sole and the baffle, thus reducing the possibility of the foot slipping.
[0022] The beneficial effects of this utility model are:
[0023] By installing reinforcement devices, patients can be firmly fixed to the support frame, preventing them from sliding or swaying when lying flat on the support cloth. This reduces the risk of patients slipping and suffering secondary injuries when the support frame is lifted, thus improving the stability and safety of patient transport. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figure 1-4 The assembled stretcher shown includes two support frames 1, which are interlocked with each other. The surface of the two support frames 1 is covered with a support cloth 2. The bottom of each support frame 1 is provided with a support leg 3. A reinforcement device 4 is provided on one side of each support frame 1. An auxiliary device 5 is provided on one side of one of the support frames 1.
[0033] Figure 2 and Figure 3The reinforcement device 4 shown includes a concave frame 41, which is fixedly connected to the support frame 1. Multiple circular holes 42 are provided on one side of the concave frame 41. A circular shaft 43 is provided inside the concave frame 41. A connecting plate 44 is fixedly connected to one end of the circular shaft 43. A pin 45 is fixedly connected to the side of the connecting plate 44 near the circular shaft 43. The size and shape of the pin 45 are adapted to the size and shape of the inner wall of the circular holes 42. The surface of the connecting plate 44 is larger than the inner wall of the concave frame 41. A strap 46 is fixedly connected to one side of the circular shaft 43. A collar 47 is fixedly connected to the end of the strap 46 away from the circular shaft 43. The support frame... A support rod 410 is fixedly connected to the side away from the concave frame 41. A screw rod 411 is fixedly connected to one side of the support rod 410. A threaded ring 412 is threaded onto the surface of the screw rod 411. A collar 47 is fitted onto the surface of the screw rod 411. The surface of the threaded ring 412 is larger than the inner wall of the collar 47. By setting up the reinforcement device 4, the patient is first placed on the support cloth 2. At this time, the collar 47 is manually moved, causing the collar 47 to move the strap 46. When the collar 47 moves to the position where it is fitted onto the surface of the screw rod 411, the threaded ring 412 is manually rotated, causing the threaded ring 412 to move left and right along the surface of the screw rod 411. When the screw ring 412 moves to the surface of the compression collar 47, it reaches the limit position of the collar 47, allowing the strap 46 to cover the patient's body. At this time, manually rotate the connecting plate 44, causing the connecting plate 44 to drive the rotating shaft to rotate, which in turn causes the connecting plate 44 to drive the round shaft 43 to rotate along the inside of the concave frame 41. During the rotation, the round shaft 43 winds up the strap 46, tightening the strap 46 around the patient's body. When the strap 46 moves and firmly fixes the patient to the support frame 1, the pin 45 aligns with the inner wall of any of the circular holes 42. At this time, manually move the connecting plate 44 towards the... Pushing the concave frame 41 causes the connecting plate 44 to move the pin 45 closer to the concave frame 41, causing the connecting plate 44 to slide the round shaft 43 along the inside of the concave frame 41. When the pin 45 moves to the position of inserting into the circular hole 42, the pin 45 cooperates with the connecting plate 44 to fix the position of the round shaft 43 and the strap 46, thereby achieving auxiliary fixation of the patient. This reduces the shaking or tilting of the support frame 1 when personnel lift it, which could cause the patient to slip due to the shaking or tilting of the support frame 1 and cause secondary injury to the patient. This improves the stability and safety of patient operation.
[0034] Figure 2 and Figure 3Multiple anti-slip strips 413 are fixedly connected to the surface of the screw hole ring 412 shown. The multiple anti-slip strips 413 are arranged at equal intervals. By setting the anti-slip strips 413, the anti-slip strips 413 can increase the friction between the hand and the surface of the screw hole ring 412, reducing the possibility of slippage when manually rotating the screw hole ring 412. A reinforcing block 414 is fixedly connected to one side of the support rod 410. The reinforcing block 414 is fixedly connected to the support frame 1. By setting the reinforcing block 414, the reinforcing block 414 can provide auxiliary support and reinforcement to one side of the support rod 410, reducing the possibility of the support rod 410 shaking or separating from the support frame 1 during use.
[0035] Figure 2 and Figure 3 A handle 48 is fixedly connected to one side of the connecting plate 44 shown. The inner side of the handle 48 is provided with multiple anti-slip protrusions. By setting the handle 48, the handle 48 can provide a point of leverage for the personnel, so that the personnel can easily rotate the connecting plate 44 by manually turning the handle 48. At the same time, the handle 48 can be used to easily insert and remove the pin 45. The end of the round shaft 43 away from the connecting plate 44 is fixedly connected to a limiting plate 49. The surface of the limiting plate 49 is larger than the inner wall of the concave frame 41. By setting the limiting plate 49, the limiting plate 49 can intercept the round shaft 43 during the movement, reducing the possibility that the end of the round shaft 43 away from the connecting plate 44 will detach from the concave frame 41 during the movement.
[0036] Figure 4 The auxiliary device 5 shown includes a circular hole rod 51, which is fixedly connected to the support frame 1. A circular rod 52 is slidably connected to the inner wall of the circular hole rod 51. A baffle 53 is fixedly connected to one end of the circular rod 52. An auxiliary plate 54 is fixedly connected to one side of the circular hole rod 51. A spring 55 is fixedly connected to one side of the auxiliary plate 54. The other end of the spring 55 is fixedly connected to the baffle 53. A circular block 56 is fixedly connected to the end of the circular rod 52 away from the baffle 53. The surface of the circular block 56 is larger than the inner wall of the circular hole rod 51. By setting the auxiliary device 5, when the patient lies flat on the support cloth 2, the spring 55 reacts, causing the spring to... 55 pulls the baffle 53 to move and make it fit against the patient's foot. When the patient accidentally slides into the gap of the support frame 1, the patient's foot pushes the baffle 53, causing the baffle 53 to move away from the round hole rod 51. The baffle 53 drives the round rod 52 and the round block 56 to move. When the round block 56 moves to the position where it fits against the surface of the round hole rod 51, the round block 56 limits the round rod 52 and the baffle 53, so that the baffle 53 intercepts the patient's foot, achieving the effect of preventing the patient from slipping. This reduces the possibility of the patient slipping when the support frame 1 is tilted significantly, and further improves the limiting effect on the patient.
[0037] Figure 4Multiple reinforcing ribs 57 are fixedly connected to one side of the baffle 53 shown. The multiple reinforcing ribs 57 are arranged at equal intervals. By setting the reinforcing ribs 57, the strength of the baffle 53 can be increased and the deformation of the baffle 53 under stress during use can be reduced. A rubber pad 58 is fixedly connected to the side of the baffle 53 away from the reinforcing ribs 57. The surface of the rubber pad 58 is provided with multiple rubber protrusions. By setting the rubber pad 58, the fit between the sole of the foot and the baffle 53 can be increased, and the friction between the patient's sole and the baffle 53 can be increased, reducing the possibility of the sole of the foot slipping.
[0038] Working principle: First, cover the two support frames 1 with the support cloth 2. Then, when using it, rotate the two support frames 1 to a horizontal position and connect them to achieve the assembly and fixation of the stretcher. Then, place it on the ground through the outriggers 3 and place the patient on the support cloth 2. Then, two people simultaneously lift the two support frames 1 to transfer the patient.
[0039] First, place the patient on the support cloth 2. Then, manually move the collar 47, causing it to move the strap 46. When the collar 47 moves to the position where it fits onto the surface of the screw 411, manually rotate the screw hole ring 412, causing it to move left and right along the surface of the screw 411. When the screw hole ring 412 moves to the position where it presses against the surface of the collar 47, it reaches its limit, allowing the strap 46 to cover the patient's body. Then, manually rotate the connecting plate 44, causing it to rotate the shaft. This causes the connecting plate 44 to rotate the round shaft 43 along the inside of the concave frame 41, allowing the round shaft 43 to rotate and compress the strap 46 during rotation. The rewinding process tightens the strap 46 around the patient's body. As the strap 46 moves and secures the patient to the support frame 1, the pin 45 aligns with the inner wall of any circular hole 42. At this point, the connecting plate 44 is manually pushed towards the concave frame 41, causing the connecting plate 44 to move the pin 45 towards the concave frame 41. This causes the connecting plate 44 to slide the round shaft 43 along the inside of the concave frame 41. When the pin 45 moves to the position of being inserted into the circular hole 42, the pin 45, in conjunction with the connecting plate 44, fixes the position of the round shaft 43 and the strap 46, thereby achieving auxiliary fixation of the patient.
[0040] When the patient lies flat on the support cloth 2, the reaction force of the spring 55 causes the spring 55 to pull the baffle 53 to move and fit against the patient's feet. When the patient accidentally slides into the gap of the support frame 1, the patient's feet push the baffle 53, causing the baffle 53 to move away from the round hole rod 51. The baffle 53 drives the round rod 52 and the round block 56 to move. When the round block 56 moves to the position where it fits against the surface of the round hole rod 51, the round block 56 limits the round rod 52 and the baffle 53, so that the baffle 53 intercepts the patient's feet, thus preventing the patient from slipping.
[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
