Multi-functional dressing for firearm perforating wound in limbs

Abstract

The invention discloses multi-functional dressing for firearm perforating wound in limbs. The multi-functional dressing for the firearm perforating wound in limbs comprises a column-shaped outer layer, a self-expansion layer is arranged in the outer layer, and developing silk is arranged in the self-expansion layer. The multi-functional dressing for the firearm perforating wound in limbs is filled in the wound, the filling number can be decided according to the wound size, after the dressing is filled, the dressing expands quickly in the blood so as to fill the wound cavity gap and form pressure in partial to play a role of hemostasis by compression; after the self-expansion layer expands, oxidized regenerated cellulose at the outer layer of the dressing fits with the tissue to play a role of hemostasis; nano-silver in the outer layer of the dressing can release slowly to develop an anti-infection effect and restrain early bacteria breeding; PVA sponge in the self-expansion layer has strong water-absorbing quality so that the PVA sponge is capable of keeping the wetness of the wound and good for healing; the dressing can be taken out through pulling the silk, the dressing silk is included in the dressing, and the dressing residue can be found through X-ray examination; the multi-functional dressing for the firearm perforating wound in limbs is featured with hemostasis, infection resistance, self expansion, adhesion resistance and easiness in taking out.

Description

technical field [0001] The invention belongs to the technical field of wound first aid equipment, and in particular relates to a multifunctional dressing for penetrating wounds of limbs and firearms. Background technique [0002] At present, the treatment principles for penetrating firearm injuries are early first aid, timely surgical debridement, and delayed suture. In the early stage of first aid, the use of dressings is the most critical technique. Traditional gauze and bandages are commonly used in clinical practice. If there is a large active bleeding, a tourniquet should be combined to stop the bleeding. But this method has the following disadvantages: [0003] Bandages have a certain hemostatic effect, but are not effective for most arterial bleeding; tourniquets can effectively stop bleeding, but prolonged use of tourniquets can easily lead to necrosis of limbs. [0004] Penetrating wounds from firearms are polluted wounds, which can easily lead to infection. Ordi...
