Small wounds that keep bleeding without clotting are related to the condition of the wound itself and the condition of coagulation, and the main reasons include vascular injury, abnormal coagulation function and the application of drugs. 1. Vascular injury: after a relatively large vascular injury, the wound will bleed continuously, which will easily lead to non-coagulation of blood. 2. Abnormal coagulation function: patients with abnormal coagulation function, such as hemophiliacs, will experience non-coagulation after bleeding. 3. Application of drugs: long-term application of anticoagulant drugs, such as aspirin and clopidogrel bisulfate, part of the coagulation status will cause a decline will also cause corresponding changes. Wound bleeding has not been coagulated, along with the bleeding continues, you need to consult a doctor in time to observe, diagnose the specific condition, under the guidance of the clinician for standardized treatment, so as not to delay the condition.
