Abstract
Abstract A connector with an injection site (3) comprising a tubular body having one or more fluid inlet (2) and a fluid outlet (5); a cap or plug made of rubber-like elastic material being fit into at least one fluid inlet to form an injection site; and a connecting (4) means being provided on the external wall of the injection site or on the external wall of the tubular body near the injection site. The connector prevents the pulling out of the needle of infusion line and the infection by the air through an injection site. The infusion needle, venous catheter and infusion tube each adapting the above connector are also disclosed.
