摘要：
This invention relates to apparatus and devices that generate sclerosing microfoams for the treatment of venous disorders, such as varicose veins. The invention includes adaptors which provide fluid connections to microfoam generating devices, to enable filling with gas and/or dispensing of the microfoam produced. The adaptors are generally cylindrical elements with open ends to enable attachment to pressurisable container on one end and are configured to enable rapid and easy attachment of a filling means or a dispensing means through the other end of the adaptor.A particular configuration comprises three or more circumferentially and downward extending cam tracks which cooperate with corresponding cams on the filling means or dispensing means and which connect a pressurisable container to a fluid path of a filling or dispensing means when the pressurisable container and filling or dispensing means are rotated relative to each other.
