Abstract: A conventional medical connector allows a gap therein to function as a passage for a flowing liquid at the cost of the flow rate of the flowing liquid. The present invention provides a medical connector which comprises a tubular resilient element. One end of the resilient element is a closed end. A through hole is disposed on the wall of the resilient element, allowing an infusion liquid to flow fluently through the cavity of the tubular resilient element. Therefore, the medical connector is effective in increasing the flow rate and thereby suitable for massive liquid infusion.
