Description

Technical Field

[0001] This utility model relates to a field first aid quick fixation stretcher, belonging to the field of stretcher technology. Background Technology

[0002] Field first aid stretchers are essential medical equipment used to transport wounded soldiers in special environments such as field combat and rescue. They are suitable for various field first aid situations, such as battlefields and disaster areas. Currently, a simplified field first aid stretcher generally consists of stretcher poles and a stretcher surface. During an emergency, two medical personnel can quickly transfer the wounded to the stretcher and secure them to the stretcher surface with straps to immobilize them. Simplified field first aid stretchers typically require two people to lift and transport. Transporting them alone is difficult, as one person would lift and drag the stretcher by one end. Therefore, field first aid stretchers with wheels at one end have also appeared on the market. These stretchers can be carried by a single person. By lifting the stretcher pole at the head end of the wounded soldier and relying on the wheels at the other end to support the ground, the transport task can be completed more easily. However, during transport, the wounded soldier often slips off the inclined stretcher surface. This is because traditional binding methods involve securing the injured person to the stretcher surface using left and right straps. When the injured person cannot control their movement and slips, gravity causes them to gradually slide down the inclined stretcher surface through the gaps in the straps. Currently, the method to prevent slippage is to add more straps. However, this increases the time required to immobilize the injured person, resulting in slower immobilization.

[0003] To address the problem of casualties slipping during transport using current field first aid stretchers, a new field first aid quick-fix stretcher has been designed. By adding quick-fix components, it can not only quickly fix the casualty but also prevent the casualty from slipping during transport. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a field first aid quick fixation stretcher, which solves the problem that current field first aid stretchers cannot quickly fix the wounded and prevent them from slipping.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A field first aid quick fixation stretcher includes two stretcher poles, the ends of which are fixed by two connecting rods to form a rectangular stretcher frame. A stretcher surface for supporting the wounded is fixed between the two stretcher poles. It also includes a sliding guardrail and a quick fixation assembly.

[0007] The sliding guardrail includes a C-shaped sliding sleeve that is fitted onto the stretcher poles on both sides and is restricted to sliding on the stretcher poles, and a guardrail fixedly connected between the two C-shaped sliding sleeves. The C-shaped sliding sleeves are locked and fixed to the stretcher poles by a quick-locking structure.

[0008] The quick-fixing assembly includes a flexible cloth bag and multiple sets of straps fixed to both sides of the flexible straps. One end of the flexible cloth bag is fixed to the middle of the stretcher surface, and the other end of the flexible cloth bag is fixed to the middle of the guardrail. As the C-shaped sliding sleeve slides from the injured person's feet to the injured person's chest, the flexible cloth bag covers the injured person's buttocks and waist from the crotch. At this time, the folded front and back sides of the flexible cloth bag are connected and bound by multiple sets of straps.

[0009] Preferably, the bottom of the stretcher rod is provided with a strip groove that runs through both ends, and the two sides of the stretcher surface are respectively fixed to a sliding rod with a diameter greater than the width of the strip groove. After the sliding rod is inserted into the stretcher rod, the two ends of the stretcher rod are closed by screw-in handles, and the stretcher surface passes through the strip groove.

[0010] Preferably, the handle includes a gripping part, and a limiting part is provided at the end of the gripping part facing one end of the C-shaped cross-section slide sleeve. The outer diameter of the limiting part is larger than the inner diameter of the C-shaped cross-section slide sleeve, thereby restricting the C-shaped cross-section slide sleeve from sliding between the two handles.

[0011] Preferably, a pair of rollers are symmetrically installed on the outer side of the stretcher pole near the foot of the injured person.

[0012] Preferably, the stretcher surface is made of flexible fabric.

[0013] Preferably, the quick-lock structure uses a hand-tightening bolt, and the stretcher rod is provided with a plurality of threaded holes that mate with the hand-tightening bolt.

[0014] The beneficial effects of this utility model are: by adding sliding guardrails and quick-fixing components, not only can the wounded be quickly fixed, but the problem of the wounded slipping during transportation can also be prevented; the sliding guardrail can cover the wounded from the feet to the hips and waist of the wounded, achieving quick fixation of the hips and waist, and the sliding guardrail itself can also slide to the chest of the wounded to provide protection; the flexible cloth bag can prevent the wounded from slipping, and the sliding guardrail can prevent the wounded from turning over and falling; the two work together to quickly fix the wounded.

[0021] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] like Figure 1 , Figure 2 As shown, this field first aid rapid immobilization stretcher includes two stretcher poles 1, with their ends fixed by two connecting rods 2 to form a rectangular stretcher frame. A stretcher surface 3 for supporting the wounded soldier 9 is fixed between the two stretcher poles 1, and the stretcher surface 3 is made of flexible fabric. It also includes sliding guardrails 4 and rapid immobilization components 5. The stretcher poles 1 and connecting rods 2 are constructed by welding or splicing tubing. The tubing is preferably made of lightweight and inexpensive aluminum alloy tubing. Lighter and more expensive carbon fiber tubing can also be used for splicing.

[0023] The sliding guardrail 4 includes C-shaped sliding sleeves 401 that are fitted onto and restricted to sliding on the stretcher poles 1 on both sides. The arc of the C-shaped sliding sleeve 401 is greater than 180 degrees, allowing it to slide on the stretcher pole 1 without detaching. A guardrail 402 is fixedly connected between the two C-shaped sliding sleeves 401. The C-shaped sliding sleeves 401 are locked to the stretcher pole 1 by a quick-locking structure 6. Both the C-shaped sliding sleeves 401 and the guardrail 402 are made of stainless steel. A lubricating layer is fixed inside the C-shaped sliding sleeves 401. The lubricating layer is made of POM engineering plastic, which has high strength and rigidity. POM's mechanical properties are close to those of metal, with high hardness and wear resistance; it also has good self-lubricating properties, a low coefficient of friction, and good sliding performance, making it suitable for manufacturing low-wear parts. A sponge sleeve (not shown in the figure) is fitted onto the guardrail 402 to prevent direct collision between the injured person and the guardrail 402 during vigorous transport, improving the comfort of the injured person during transport.

[0024] like Figure 1-Figure 4 As shown, the quick-fix component 5 includes a flexible cloth bag 501 and multiple sets of straps 502 fixed to both sides of the flexible straps 502. One end of the flexible cloth bag 501 is fixed to the middle of the stretcher surface 3, and the other end is fixed to the middle of the guardrail 402. The flexible cloth bag 501 has a shape that is wide at both ends and narrow in the middle, making it easy to put on the hips. As the C-shaped cross-section sliding sleeve 401 slides from the feet of the injured person 9 to the chest of the injured person 9, the flexible cloth bag 501 covers the hips and waist of the injured person 9 from the crotch. At this time, the front and back sides of the folded flexible cloth bag 501 are connected and secured by the multiple sets of straps 502. The straps 502 are Velcro straps 502, which can be quickly secured. The hook side of the Velcro strap 502 is fixed to the strap, and the loop side of the Velcro strap 502 is fixed to the flexible cloth bag 501. When the flexible cloth bag 501 is worn on the buttocks of the injured person, the hook side and the loop side of the Velcro strap 502 are glued together.

[0025] like Figure 1-Figure 3 As shown, to facilitate the installation and replacement of the stretcher surface 3, the bottom of the stretcher rod 1 is provided with a strip groove 102 that runs through both ends. The two sides of the stretcher surface 3 are respectively fixed to sliding rods 301 with a diameter larger than the width of the strip groove 102. After the sliding rods 301 are inserted into the stretcher rod 1, the two ends of the stretcher rod 1 are closed by screw-on handles 8. The sliding rods 301 are confined within the cavity of the stretcher rod 1 between the two handles 8, and the stretcher surface 3 protrudes through the strip groove 102. After removing the handles 8, the stretcher surface 3 and the sliding rods 301 on both sides can be quickly removed from the cavity of the stretcher rod 1.

[0026] The handle 8 includes a gripping part 801. A limiting part 802 is provided at the end of the gripping part 801 facing the C-shaped cross-section sliding sleeve 401. The outer diameter of the limiting part 802 is larger than the inner diameter of the C-shaped cross-section sliding sleeve 401, thus restricting the sliding of the C-shaped cross-section sliding sleeve 401 between the two handles 8. The handle 8 is made of stainless steel and is fixed to the stretcher pole 1 by threads. The gripping part 801 of the handle 8 is covered with a non-slip rubber sleeve.

[0027] To facilitate single-person transport of the wounded soldier 9, a pair of rollers 7 are symmetrically installed on the outer side of the stretcher pole 1 near the feet of the wounded soldier 9. During transport, after the wounded soldier 9 is secured, the handle 8 at the head end of the wounded soldier 9 is lifted, and the stretcher pole is used as a trolley for transport. For the stretcher pole 1 made of aluminum alloy tubing, the rollers 7 are mounted on an aluminum alloy support plate welded to the stretcher pole 1.

[0028] To achieve quick locking of the sliding guardrail 4, the quick-lock structure 6 uses hand-tightening bolts. Multiple threaded holes 101, which mate with the hand-tightening bolts, are arranged sequentially and at equal intervals on the stretcher pole 1. Based on the body shape of the injured person 9, the sliding guardrail 4 is slid to the corresponding height of the threaded hole 101, and then fixed in place by the hand-tightening bolts.

[0029] like Figure 4 , Figure 5 As shown, the injured were being transported at 9:00 AM:

[0030] (1) First, place the stretcher flat on the ground, and slide the C-shaped section sliding sleeve 401 of the sliding guardrail 4 and the guardrail 402 to the end of the roller 7 of the stretcher pole 1.

[0031] (2) Carry the injured person 9 into the stretcher surface 3. At this time, the legs are slightly separated. Slide the C-shaped sliding sleeve 401 and the guardrail 402 of the sliding guardrail 4 towards the chest of the injured person 9. After the flexible cloth bag 501 covers the crotch and buttocks of the injured person 9, use the multiple sets of straps 502 on the flexible cloth bag 501 to connect and bind the front and back sides of the flexible cloth bag 501. The flexible cloth bag 501 can prevent the injured person 9 from slipping. The sliding guardrail 4 prevents the injured person 9 from turning over and falling. The sliding guardrail 4 itself slides to the chest of the injured person 9, which plays the role of preventing the injured person from being thrown out of the stretcher.

[0032] (3) Lock the quick-lock structure 6 to fix the C-shaped cross-section sliding sleeve 401 of the sliding guardrail 4 to the stretcher pole 1;

[0033] (4) Lift the stretcher handle 88 of the head of the wounded 9 and transport the wounded 9 at an angle by relying on the rollers 7 at the bottom; or two people can lift the stretcher together to transport the wounded 9.
