Problems solved by technology

But its disadvantages are equally obvious: ① First, it does not have hemostatic function
In many battle wounds that bleed a lot, it is necessary to use a tourniquet or hemostatic powder, which makes the operation complicated
In addition, the existing hemostatic powder (such as zeolite) is easy to generate heat, which will aggravate tissue damage; the tourniquet cannot be used for a long time, and it is easy to cause necrosis of limbs
②Secondly, it does not have anti-infection effect
However, after a lot of clinical practice, it has been found that this new type of dressing has a poor ability to drain exudate. If there is more blood or exudate on the wound surface, it will usually accumulate between the dressing and the wound surface, making the dressing unable to adhere closely to the wound surface and cannot play an effective role. biological effects, and even aggravate local infection
In addition, the hemostatic function of chitosan dressing is limited, it can only stop venous bleeding or bleeding of small arteries, and it is not effective for bleeding of large arteries
Polyvinyl formal sponge is a new type of synthetic dressing, which has a strong ability to absorb exudate, and can quickly expand when exposed to water, but it does not have biological effects of anti-infection and promotion of healing
In addition, whether it is chitosan dressing or polyvinyl formal sponge, the toughness and tensile strength of both are not enough, which is not conducive to pressure bandaging

Abstract

The invention discloses a bandage dressing special for limb war wound first aid, and belongs to the technical field of medical dressings. The bandage dressing is composed of a dressing body and a bandage; the dressing body sequentially comprises an inner layer dressing, a middle layer dressing and an outer layer dressing from the side making contact with the war wound part; the inner layer dressing adopts a non-woven fabric layer formed by blending chitosan fibers and oxidized regenerated cellulose and is used for stopping bleeding and absorbing wound secreta; the middle layer dressing adopts a polyvinyl formal spongy layer and is used for absorbing oozing liquid discharged from meshes and pressing to stop bleeding; the outer layer dressing adopts a cotton weaving gauze layer and is used for fixing and binding; the inner layer dressing is rich in antibacterial agent, and multiple penetrating drainage holes are formed in the inner layer dressing in the thickness direction; a two-way semi-transparent film is arranged between the middle layer dressing and the outer layer dressing. The bandage dressing has the advantages of being reasonable in structural design, efficient in stopping bleeding, resistant to infection, capable of moisturizing and promoting healing, convenient to use and the like.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a special first-aid dressing for limb war injuries.
