Description

Catheter GUIDE SYSTEM

The present invention relates to a catheter guide system, and more particularly, to a catheter guide system that guides the catheter to be accurately inserted into a desired target vessel regardless of the skill of the operator.

In the medical field, a medical device including a syringe and a catheter is used for treatment or biopsy. However, when the operator uses the syringe, when the syringe is inserted into the patient's body, the inside of the body cannot be seen at all, so it is difficult to determine the position of the inserted syringe needle or the degree of insertion.

For example, if the operator wants to draw blood from a specific blood vessel of a patient, it may take a considerable amount of time to determine the exact location of the blood vessel or determine the degree of penetration of the syringe.
