によってカテーテルの形状を変えることができない。However, the former, which has been described in the prior art, has the following drawbacks. B) Since the catheter is designed to be used in the digestive tract, it cannot be seen in the X-rays inside the blood vessel, so the deformed shape of the catheter and the entire catheter cannot be seen.
Cannot be used in blood vessels. B) Since the catheter is a hard Teflon, a small diameter curve cannot be made inside the blood vessel and it cannot be used. C) Since the material of the catheter is Teflon, the tip is hard and dangerous, and the catheter alone cannot be inserted to the target position in the blood vessel. D) Since the stopcock does not have a hemostatic component, leakage of blood vessels occurs and patient blood loss is large. E) Since the catheter is Teflon, the shape of the catheter cannot be changed by thermal deformation.
