Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a folding stretcher for battlefield rescue. BACKGROUND

[0002] In the medical rescue of battlefield environment, the stretcher is one of the important tools for the rapid escort and transport of wounded soldiers. At present, most of the portable stretchers used in battlefield first aid are pole stretchers. For the pole stretcher, the wounded soldier is clamped between the two stretcher poles. When the stretcher is used, the stretcher cloth will bend downward under the action of the gravity of the wounded person's body, forcing the two long poles to approach each other, which easily squeezes the wounded soldier, making the wounded soldier more seriously injured.

[0003] When the stretcher is folded, the four legs on the stretcher pole cannot be detached, which not only occupies a large space, is not easy to carry and manage, and is difficult to use flexibly in snowfield battlefield, mountain battlefield and jungle battlefield.

[0004] At the same time, in wartime, the soldiers lifting the stretcher are occupied with both hands, greatly reducing the opportunity to protect themselves on the battlefield, and also reducing the opportunity to protect the comrades on the stretcher.

[0005] Therefore, it is necessary to provide a stretcher which is convenient to carry and manage and suitable for use in battlefield environment. SUMMARY

[0006] The present application provides a folding stretcher for battlefield rescue, which comprises a carrying part, a longitudinal telescopic part, a transverse telescopic part and a T-shaped connecting piece.

[0034] As Figures 1 to 8 shown:

[0035] The application provides a folding stretcher for battlefield rescue, which comprises a carrying part 4, a longitudinal telescopic part, a transverse telescopic part 5 and a T-shaped connecting piece 3.

[0036] Preferably, the longitudinal telescopic part comprises a longitudinal telescopic rod 1, a first longitudinal sleeve 2a and a second longitudinal sleeve 2b; and the transverse telescopic part 5 comprises a transverse telescopic rod 51 and a transverse sleeve 52.

[0037] Preferably, the carrying part 4 comprises a carrying strap 41, a shoulder fixing piece 43 for fixing the carrying part 4 on the shoulder of a stretcher bearer, and an elastic piece 42 detachably fixed on the shoulder fixing piece 43 and used for binding the relative position of the shoulder fixing piece 43.

[0041] Further, preferably, the U-shaped stretcher plate 25 is provided with a second directional slot 251 on the inner side of the U-shaped opening; and the inner grooves 242 on both sides of the end of the T-shaped stretcher plate 24 away from the binding piece 22 are respectively provided with a positioning shaft 241.

[0042] Furthermore, preferably, the T-shaped stretcher plate 24 is provided with a positioning member 6, a third shaft hole 63 that cooperates with the positioning shaft 241, a first abutting part 61 that abuts against the wall of the second directional groove 251, and a second abutting part 62 that abuts against the wall of the inner groove 242.

[0043] Furthermore, preferably, the stretcher board is made of bulletproof material that can withstand bullets.

[0044] Preferably, the T-shaped connector 3 includes a horizontal portion and a vertical portion. The horizontal portion is provided with a second shaft hole 32, and the first longitudinal sleeve 2a and the second longitudinal sleeve 2b are rotatably fixed to the T-shaped connector 3 through a fixed shaft 33. The vertical cross section of the T-shaped connector 3 is U-shaped, and a clearance groove 31 is provided on the horizontal portion on the side of the U-shaped opening facing the stretcher plate, which is used to make way for the first fixing member 26 on the longitudinal sleeve 2.

[0045] Preferably, the lateral telescopic part 5 includes a lateral telescopic rod 51 and a lateral sleeve 52; one end of the lateral telescopic rod 51 is provided with a second fixing member 511, which is fixedly connected to the first fixing member 26; the part near the other end is provided with symmetrical second locking pins 512; one end of the lateral sleeve 52 is provided with a third fixing member 521, and the end away from the third fixing member 521 is provided with a second locking hole 522 that cooperates with the second locking pin 512.

[0046] like Figure 2 , Figure 7 The T-shaped connector 3 connects the first longitudinal sleeve 2a and the second longitudinal sleeve 2b together via the fixed shaft 33, and assembles two sets. The second fixing member 511 and the third fixing member 521 of the transverse telescopic part 5 are respectively fixed to the first fixing member 26 on the longitudinal sleeve 2 by bolts. The first abutting part 61 of the positioning member 6 on the T-shaped stretcher plate 24 is placed into the second directional groove 251. The longitudinal telescopic rod 1 is placed into the first longitudinal sleeve 2a and the second longitudinal sleeve 2b respectively, and the fixed shaft 33 passes through the first shaft hole 28 through the first directional groove 13. In this embodiment, the length of the first directional groove 13 is less than the length of the longitudinal telescopic rod 1, and under the action of the fixed shaft 33, the longitudinal telescopic rod 1 is restricted in the longitudinal sleeve 2. The two shoulder straps 41 of the carrying part 4 are respectively connected to the corresponding carrying base 21, and the elastic member 42 connects the two shoulder clips 43. In some other embodiments, welding or riveting can be used for fixing.

[0047] In use, the first longitudinal sleeve 2a and the second longitudinal sleeve 2b of the stretcher are moved away from each other until the second locking pin 512 of the transverse telescopic part 5 passes through the second locking hole 522, and the first abutting part 61 abuts against the groove wall of the second directional groove 251. At this time, it can be assembled as follows.Figure 1 A folding stretcher for battlefield rescue. After the second locking pin 512 of the transverse telescopic part 5 passes through the second locking hole 522, the relative position of the transverse telescopic rod 51 and the transverse sleeve 52 is fixed, and the weight of the wounded body of the first longitudinal sleeve 2a and the second longitudinal sleeve 2b approaching each other is resisted, preventing the wounded soldier from being crushed.

[0048] When folding, the first locking pin 14 of the longitudinal telescopic rod 1 is removed from the first locking hole 23 and moved deeper into the longitudinal sleeve 2 until the first locking pin 14 is engaged in the third locking hole 29. At this time, the longitudinal telescopic rod 1 is fixed inside the longitudinal sleeve 2. Further, the second locking pin 512 of the transverse telescopic rod 51 is removed from the second locking hole 522, the first longitudinal sleeve 2a and the second longitudinal sleeve 2b move closer to each other, and the second locking pin 512 is engaged in the fourth locking hole 523. At the same time, the first abutting part 61 of the positioning member 6 abuts against the end of the second directional groove 251 near the binding member 22. Then, the longitudinal telescopic part is rotated towards the horizontal part of the vertical T-shaped connector 3 and abuts against the vertical part of the T-shaped connector 3. Then, the entire back support 4 abuts against the folded longitudinal sleeve 2. Finally, the back support 4 and the folded longitudinal sleeve 2 are tied together using restraint straps (used to restrain the injured person to the stretcher, not shown in the figure). This design makes the folded stretcher a single unit, allowing soldiers to carry it quickly on their backs using the shoulder strap 43. The stretcher's bulletproof material provides some protection against artillery fire. This design eliminates the stretcher legs found in existing technologies, resulting in a smaller, more manageable folded stretcher. Furthermore, the Z-shaped handle 11 is suitable for flexible use in mountainous, snowy, and jungle environments.

[0049] In this embodiment, an infusion fixing component 8 is also provided for fixing the infusion rod.

[0050] In this embodiment, preferably, the infusion fixation member 8 is disposed on the longitudinal telescopic part.

[0051] In some other embodiments, preferably, the infusion fixation member 8 is disposed on the transverse telescopic portion 5.

[0052] The above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
