The depth of the wound can be initially determined by checking the shape of the wound, the amount of bleeding, the degree of pain felt and the movement of the limbs.
1. Check the shape of the wound: if the wound appears to be flattened, and the muscles and bones are visible to the naked eye, it means that the wound is deep.
2. Bleeding: If there is a blood flow, it means that the larger blood vessels have been injured, and the larger blood vessels are usually in the deeper parts of the body.
3. The degree of pain: if the pain after the injury is severe or directly unable to perceive the pain, suggesting that the wound is deeper, the condition is serious.
4. Movement: If the distal part of the injured part cannot control the movement, it means that the motor nerve and tendon have been injured.
All of the above situations suggest that the wound is deeper and more serious, and it is recommended that the patient go to a regular medical institution as soon as possible for early treatment.
