摘要

The valve (1) has a non-return flap (2) allowing passage of fluid or air and fluid with corresponding high pressure in the direction in a body of a patient. The valve is opened by force of a mass of the fluid or high pressure of the air in the direction and closed in a reverse direction by inertia of the flap. The valve exclusive of the flap is made of hard plastic material. A guide part (3) is made of rubber material and is fastened to a thinner end of a guide pipe, which is made of hard plastic material.
