Abstract: There is provided a medicinal liquid injection port to be implanted subcutaneously. A housing main body is provided with a medicinal liquid storage portion therein, an opening portion that opens the medicinal liquid storage portion, and a discharge hole that communicates with the medicinal liquid storage portion and configured to be connected with a tube. A septum attached to the opening portion of the housing main body and provided with a puncturable region that can be punctured with a puncture needle. A contrast portion is disposed in the septum over a thickness direction of the septum so as to detect the puncturable region of the septum with the ultrasonic wave. The contrast portion is provided in the septum within a thickness region of the septum and all of the contrast portion is positioned at an inner side of the septum in the thickness direction of the septum.

Abstract: A medical tube, which is inserted into a tubular organ and discharges and suctions fluid, is provided with a tube-shape main body which extends a prescribed length and with a valve which is disposed in a portion of the main body that is inserted into the tubular organ and can discharge or suction a fluid, wherein the valve includes multiple slits which are formed so as to extend axially of the body a prescribed length, reaching from the outer periphery to the inner periphery of the main body, and which are provided spaced in the circumferential direction of the main body. Each slit is formed tilted in the same direction with respect to a radially-extending line which passes through the axial center of the main body.
