Wound protection film and use method thereof

Abstract

The invention relates to medical care supplies and use methods of the medical care supplies, and in particular relates to a wound protection film and a use method of the wound protection film. The wound protection film comprises a back flow mechanism, a bleeding stopping mechanism as well as a medicine layer, an active carbon fiber layer and a waterproof sticking layer which are adjacently arranged in sequence; the back flow mechanism comprises a cavity and a plurality of connecting pipes; the bleeding stopping mechanism comprises an air bag, an air inlet unit and a pushing unit; the air inletunit comprises an air inlet pipe, a push rod and a piston; the pushing unit comprises a tension spring, a pushing pipe and a pushing rod. The use method of the wound protection film comprises the following steps: S1, inflating the air bag; S2, carrying out bleeding stopping on the wound by utilizing the swelling of the air bag; S3, enabling a puncture needle to puncture the film; S4, carrying outdrying on the wound by utilizing air in the air bag; and S5, enabling water, electrolyte and protein to flow to the wound again. When the technical scheme is adopted, while bleeding stopping is carried out on the wound and bacteria and necrotic leucocytes at the wound are removed, the loss of water, electrolyte and protein can not be caused.

Description

technical field [0001] The present invention relates to a medical care article and its use method, in particular to a wound protection film and its use method. Background technique [0002] The skin is the largest organ covering the surface of the human body, and it is the first line of defense to protect the human body from the invasion of foreign pathogens. In the case of a wound on the skin of the finger, in order to heal the wound smoothly, a wound covering film is generally used to cover the wound, so as to provide a better healing environment and avoid wound infection. [0003] Existing wound covering films generally consist of an adhesive layer, a drug layer and a protective layer. During use, the protective layer is torn off, the drug layer is aligned with the wound, and the adhesive layer is bonded and fixed on the finger. However, in actual use, it will be found that the wound will produce some secretions during the healing process. After testing, it is found that...

[0004] At the same time, although the drug layer of the existing wound covering film contains blood coagulation drugs, if the wound is too large, it still cannot play a hemostatic effect in a short time. In order to avoid unnecessary blood loss, it is often necessary to press the blood with the fingers of the other hand. Hold the wound to stop the bleeding. On the one hand, it is inconvenient to press the wound with your fingers. On the other hand, if you use improper force, it will cause the skin around the wound to turn white, and in severe cases, the skin around the wound will become necrotic.
