You havent given your daughters age, since the first injury
occured a week back and a good scab has been formed means it was healing.
But due to reinjury the scab came off and again started to bleed.
If your child hasnt immunized for tetanus
get her a tetanus toxioid vaccination
Since there is pus and wound smells, it is likely to be infected,
Look for her body temperature, if it is high she needs medical attention
Wash the wound thoroughly with plain water and get some antibiotics like cotrimoxazoles and if she is in pain she may need antibiotics.
