Disclosed is a vascular access apparatus including a needle having an internal lumen to communicate with a blood passage and implanted in the patient's body, a driving part for transporting the needle in a manner such that the needle tip is expelled from the patient's body, and a controlling part for controlling the operation of the driving part in response to a signal. The vascular access apparatus is advantageous in that it is convenient to use because needle insertion and removal motions are automatically performed, repetition of needle piercing is not required because the needle can be precisely inserted into a target position, it is possible to reduce the number of needle piercing motions, thus reducing the number of times that pain is applied to a patient, and it is possible to alleviate the degree of pain applied to a patient because needle piercing is performed without being anticipated by the patient. |
