Abstract
A coupling system for transferring liquid anaesthetic from a bottle to a vaporizer has a first part, having a first valve with a first spring-loaded valve body and a first counter body, and a second valve part, having in the corresponding fashion a second valve with a second spring-loaded valve body and a second counter body, the first part and the second part being interconnectable. The first counter body is devised to act on the second spring-loaded valve body in an opening direction, and the second counter body is devised to act on the first spring-loaded valve body in an opening direction to form a path of flow for the liquid anaesthetic. Leakage of liquid into atmosphere is reduced since the first spring-loaded valve body and the first counter body are arranged so they, in a closed position, form an essentially flat first surface, and the second spring-loaded valve body and the second counter body are arranged in the corresponding way so they, in the closed position, form an essentially flat second surface.
