A ruptured blood vessel may or may not be repaired automatically, depending on the diameter of the ruptured blood vessel, the anatomical relationship between the ruptured blood vessel and the surrounding tissues, and the body’s coagulation function. Whether ruptured blood vessels can be automatically repaired and the length of specific repair and hemostasis, according to the size of the ruptured blood vessel, the length of the rupture opening and the coagulation and hemostatic function, and even the general health status of the body to make a judgment on a variety of factors, generally like the skin and other superficial small capillary rupture, can be within a certain period of time to stop the bleeding and restoration. Rupture of blood vessels may not be automatically repaired, for example, in hemophilia, oral anticoagulant drugs or other systemic conditions, the coagulation and hemostasis mechanism is impaired, resulting in continuous bleeding and difficult to seal and repair the wound; in addition, most of the arterial and venous blood vessels due to the diameter of the thicker, rupture can not be automatically repaired, and need to be compressed to stop the bleeding and surgical suturing to achieve the purpose of bleeding restoration. It is recommended that when bleeding and coagulation time is long and bleeding in critical areas poses a major threat to life and health, it is necessary to consult a doctor in time and take appropriate measures.
