Applicable scenarios of pressure bandages
Bleeding wounds: If you accidentally cut your arm with a knife in daily life, the wound is deep and bleeding a lot, the pressure bandage can apply pressure around the wound to slow down the blood flow and achieve the purpose of hemostasis.
After surgery: Some surface surgeries, such as lipoma removal surgery, may have the risk of bleeding in the postoperative wound. The use of pressure bandages can help reduce bleeding and promote wound healing.
Applicable scenarios of fixed bandages
Fractures: Taking leg fractures as an example, fixed bandages can be bandaged and fixed from the upper and lower ends of the fracture site to keep the fracture ends in a relatively stable position. This is crucial to prevent bone dislocation at the fracture site and avoid damage to surrounding muscles, blood vessels and nerves.
Joint sprains: When the ankle is sprained, the fixed bandage can fix the ankle in a suitable position and limit its range of motion. This can reduce further stretching or damage to the injured ligaments and relieve pain and swelling.
Application scenarios of hemostatic bandages
Emergency arterial bleeding: For example, in an accident, the femoral artery is punctured and causes heavy bleeding. The hemostatic bandage can be quickly applied to the wound, and a special hemostatic mechanism (such as containing hemostatic drugs or a strong compression structure) is used to stop the outflow of arterial blood as soon as possible, so as to buy time for subsequent medical rescue.
Severe traumatic bleeding: In some serious open traumas, such as large-area lacerations of limbs caused by car accidents and severe bleeding, hemostatic bandages can quickly control bleeding.
Application scenarios of cotton gauze bandages
General wound dressing: In the family, if a child accidentally falls and scratches his knee, after cleaning and disinfection, a cotton gauze bandage can be used for bandaging, which can protect the wound from external contamination and absorb the tissue fluid exuded from the wound.
Fixation after applying medicine: In the hospital, when the doctor applies medicine to the patient's wound, the cotton gauze bandage can be used to fix the medicine so that it is in close contact with the wound, exerts the efficacy of the medicine, and keeps the wound clean at the same time.
Elastic bandage application scenarios
Auxiliary treatment of varicose veins in the lower limbs: For patients with varicose veins in the lower limbs caused by long-term standing work, elastic bandages are bandaged from the feet upwards to provide moderate pressure, promote blood return in the lower limb veins, and relieve symptoms of varicose veins, such as soreness and heaviness in the legs.
Orthopedic rehabilitation period: In the later rehabilitation stage of fracture healing, elastic bandages can be used to bandage injured limbs to provide certain pressure support, which helps to reduce swelling. At the same time, it can also protect the injured part to a certain extent and prevent re-injury.
