Description
Technical Field
The invention belongs to the field of medical auxiliary instruments, and particularly relates to a scar removing patch.
Background
Skin wounds, especially after burn healing, trauma and surgery, leave scars which can affect the aesthetics of the body, produce painful itching, and reduce the quality of life. The main physical treatment method at present is to apply pressure through the binding of the bandage or the elastic clothing, so as to achieve the effect of scar removal. This approach is suitable for scar treatment of large-area wounds, which has the following drawbacks for small-area wound scar treatment: on one hand, the small-area wound is inconvenient to bind, and discomfort and inconvenience are easily brought to the daily life of a patient; on the other hand, because various concave parts exist on the surface of the human body, such as the chest, the spine and other areas, the pressurizing effect is often not achieved when the elastic clothing is bound or worn by using the bandage. The silica gel scar removing patch commonly used in clinical treatment can only play a role in moisturizing the surface of the scar and relieving itching, and can not apply pressure to the scar, so that a better treatment effect is achieved.
The negative pressure scar removing patch is inoculated to solve the problems, however, the existing negative pressure scar removing patch applies pressure on the surface of the scar through negative pressure suction, so that the scar tissue lacks blood supply and oxygen supply, and necrosis apoptosis of fibroblasts in the scar is promoted, thereby realizing the function of treating the scar.
The tension reducer is a wound treatment apparatus commonly used at present, and replaces the traditional needle and line sewing mode or the skin nail sewing mode. The skin tension reducer slightly reduces tension on two sides of the wound, is beneficial to wound rehabilitation, and can avoid the phenomenon that the wound is pulled due to high skin tension when the face moves.
The existing negative pressure patch can not be organically combined with a tension reducer.
