Abstract
A valve body and a medical instrument provided with the valve body can stably maintain sealing performance for preventing air/blood leakage while maintaining a smooth insertion feeling even when various types of medical devices are repeatedly inserted and removed. The valve body includes a main body portion having oppositely facing first and second surfaces, an outer peripheral surface extending between the first and second surfaces, and an insertion portion having an inner surface defining a gap that allows insertion of a medical device and formed at least on the first surface. The main body portion contains a self-repairing material that allows self-repairing damage resulting from contact with the medical device. At least part of the inner surface of the insertion portion is provided with a coating layer that prevents the gap from being closed by self-repair when portions of the inner surface of the insertion portion contact each other.
