Description

Technical Field

[0001] This utility model belongs to the field of fire rescue tools, specifically a multi-functional rescue stretcher for fire rescue. Background Technology

[0002] In fire and rescue operations, rescue stretchers are crucial equipment for transferring the injured. However, existing rescue stretchers have many limitations in practical application. On the one hand, most stretchers have a fixed shape and can be used normally in spacious areas, but in complex scenarios such as narrow corridors and gaps in rubble, their large size makes them difficult to maneuver, preventing the timely transfer of the injured. Even some stretchers with folding functions are still quite bulky after folding, increasing the burden on firefighters and affecting rescue efficiency. On the other hand, existing stretchers use relatively simple methods to secure the injured, relying solely on simple straps. During transport in rugged terrain or emergency transfers, the injured's limbs are prone to shaking and displacement, especially for patients with spinal injuries, which not only fail to provide effective support and fixation but may also cause secondary injuries. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a multi-functional rescue stretcher for fire rescue, which solves the problems of existing rescue stretchers being large in size, having poor adaptability, having a single fixing method, being prone to causing secondary injury to the injured, and affecting rescue efficiency.

[0004] A multi-functional rescue stretcher for fire and rescue, comprising:

[0005] The first stretcher assembly includes a C-shaped frame, on which two support arms are fitted with a support cloth for supporting the upper body of the wounded. The support cloth includes a connecting sleeve connecting the support area of ​​the wounded and a support part fitted on the support arms.

[0006] The second stretcher assembly includes two L-shaped blocks hinged to one arm of a C-shaped frame. A second C-shaped frame is provided on the L-shaped blocks, and several support straps for supporting the lower body of the injured person are fitted on the two arms of the second C-shaped frame.

[0007] The fixation components include a first fixation component and a second fixation component disposed on the first and second inverted frames for fixing the limbs of the injured person;

[0008] The movable wheels are located on the outer sides of the two support arms of the C-shaped frame, and their rotation axis is coplanar with the axis of the C-shaped frame, which is used to move the stretcher.

[0009] The locking block, set on the L-shaped block, is used to engage with the end of the C-shaped frame to achieve the switching of the stretcher length.

[0010] Preferably, the first fixing component includes at least two pairs of first fixing straps arranged on the outrigger, and a quick connector is provided at one end of each first fixing strap that is close to the other for quickly fixing the injured person's limb.

[0011] Preferably, the second fixation component includes at least two second fixation straps disposed on the C-shaped frame, and the ends of the second fixation straps are provided with quick connectors for cooperating with the first fixation component to perform cross-fixation on the injured person.

[0012] Preferably, both the first and second C-shaped frames are made of hollow tubes, and the L-shaped block is hinged to one arm of the C-shaped frame. When folded, the stretcher can be in the form of a short stretcher, which can be used with the wheels to enable single-person transport.

[0013] Preferably, the quick connector one and quick connector two adopt a detachable connection structure, and the first fixing strap, the second fixing strap, the support strap and the support cloth are made of high temperature resistant woven material.

[0014] Preferably, when the L-shaped block and one arm of the C-shaped frame are extended in a straight line, the locking block engages with one end of the C-shaped frame, so that the first stretcher assembly and the second stretcher assembly form a long stretcher shape for multi-person collaborative transport.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, through the ingenious design of L-shaped blocks and locking blocks, can quickly switch between the length and shape of the stretcher. In a spacious area, the second stretcher component can be unfolded to form a long stretcher, which is convenient for multiple people to carry together; in a narrow space, the second stretcher component can be folded and, with the help of the wheels, firefighters can drag the stretcher through narrow passages by themselves, which effectively solves the problem of traditional stretchers being difficult to operate in complex environments and greatly improves rescue efficiency.

[0017] 2. This utility model, through the cooperation of the first and second fixing components and the quick-connect fitting, can form a cross-fixation at the shoulder and chest and waist and hip of the injured person. This fixing method is firm and easy to operate, effectively restricts the movement of the injured person's limbs, provides stable support for special patients such as those with spinal injuries, and significantly reduces the risk of secondary injury during transportation.

[0018] 3. This utility model utilizes a hollow tube construction for the stretcher, resulting in a lightweight design that reduces the burden on firefighters. When folded, it is compact and easy to carry and store. Furthermore, the support fabric, straps, and securing straps are made of high-temperature resistant woven materials, making it suitable for high-temperature fire scenes. Additionally, the inclusion of wheels enables the stretcher to be towed, achieving multi-purpose functionality and meeting the diverse needs of different rescue scenarios.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] As attached Figure 1 To be continued Figure 3 As shown:

[0026] This utility model provides a multi-functional rescue stretcher for fire rescue, including a first stretcher assembly 1, a second stretcher assembly 2, a first fixing assembly 3, a second fixing assembly 4, and moving wheels 5.

[0027] As attached Figure 1 To be continued Figure 3 As shown: The first stretcher assembly 1 includes a U-shaped frame 101, with a support cloth fitted on its two arms. The support cloth includes a connecting sleeve 102 disposed between the two arms of 101, and support portions 103 respectively fitted on the corresponding sides of 101, used to support the upper body of the injured person. The U-shaped frame 101 is made of hollow tube, which is lightweight and strong, making it easy for firefighters to operate.

[0028] As attached Figure 2 To be continued Figure 3 As shown: The second stretcher assembly 2's C-shaped frame 201 also uses a hollow tube. Two L-shaped blocks 203 are hinged to the support arms of the first C-shaped frame 101. Several support straps 202 are fitted onto the two support arms of the second C-shaped frame 201 on the L-shaped blocks 203 to support the lower body of the injured person. A locking block 6 is provided near the end of the L-shaped block 203, which can be engaged with the end of the first C-shaped frame 101. The movable wheels 5 are installed on the outer sides of the two support arms of the first C-shaped frame 101, and their rotation axis is coplanar with the axis of the first C-shaped frame 101.

[0029] As attached Figure 3 As shown: The first fixing component 3 includes two paired first fixing straps 301 mounted on the outrigger, with a set of quick-connecting parts 302 at one end of each first fixing strap 301 for use. The second fixing component 4 includes two second fixing straps 401 mounted on 101, with a set of quick-connecting parts 402 at the ends of each second fixing strap 401 for use, used to fix the injured person's limbs. Both quick-connecting parts 302 and 402 are snap-fit ​​structures, using commonly used interlocking snap-fit ​​fasteners. The first fixing straps 301, second fixing straps 401, support straps 202, and support fabric are all made of Kevlar woven material, improving the material's applicability and ensuring it will not become unusable due to high temperatures.

[0030] Working principle: In a spacious rescue space, unfold the second stretcher assembly 2 so that the L-shaped block 203 is aligned with the arm of the C-shaped frame 101. Insert the locking block 6 into the end hole of the C-shaped frame 101. At this time, the supporting cloth and the supporting strap 202 form a continuous supporting surface, forming a long stretcher (total length 1.8m), which allows multiple people to work together to transport the injured.

[0031] When it is impossible to carry the patient in a narrow space, the L-shaped block 203 is folded so that the hinge point is located on the upper side of the C-shaped frame 101 and the moving wheel 5 touches the ground, allowing the upper body of the injured person to be placed on the C-shaped frame 101 while the lower body is suspended in the air. Firefighters can then drag the stretcher along the ground by themselves and easily pass through a 60cm wide passage.

[0032] After the rescue is completed, disassemble block 6 and fold L-shaped block 203 to fit the two components together, reducing the size of the stretcher and making it easier to carry.

[0033] When transferring the wounded, first lay them flat on the support fabric. Use the first fixation strap 301 to pass through the quick connector 302 and secure the wounded's shoulders. Then use the second fixation strap 401 to cross and secure the waist, quickly completing the fixation and ensuring the stability of the wounded's limbs. If the wounded has a spinal injury, a hard board (optional accessory) can be placed under the support fabric to enhance the support rigidity.
