All preoperative examinations do not need to be removed from the first-aid bag, the patient is not moved many times in the examination and diagnosis process, and secondary injury is reduced and avoided.

[0033] 5. This design uses at least two pieces of elastic and non-elastic fabric, with half of each piece located on the left and half on the right sides of the foam bag. This allows for free bending at the elbows or knees when the arm or leg is bent.

[0034] 6. This design uses metal snaps or Velcro for fastening. This allows for quick and easy fastening, saving time and promoting better curing of the foam material to the injured area. Multiple metal snaps or Velcro can be used to adjust the tightness of the elastic and non-elastic fabric wrapping to accommodate different body shapes.

[0035] 7. This design features multiple pairs of straps on both sides of the foam bag, connected by buckles. After the foam bag is shaped, the straps can be fastened to securely hold the injured area inside the pre-formed, wrap-around first-aid bag, preventing secondary injury to the patient due to bumps or other disturbances.

[0036] 8. The foam bag in this design also has multiple pairs of hand loops on both sides for carrying or threading through stretcher poles. These hand loops can be made of a tough material to facilitate lifting the patient or threading them through the long poles for use as a stretcher to transfer the injured to the hospital or ambulance.

[0037] 9. The inner layer of this foam bag is made of waterproof fabric or plastic film that is not easy to leak, while the outer layer is made of abrasion-resistant fabric. The inner layer can prevent the foam material from leaking out, and the outer layer can adapt to different external environments, such as construction sites, accident scenes, mountains or battlefields, to avoid punctures and damage.

[0038] 10. The foam bag in this design is specially designed with an internal structure that facilitates the even distribution of foam material. Different shapes are designed for different parts. After foaming, the human body or limbs are wrapped, and the forming effect is very ideal.
