摘要：
A device is described for facilitating the preparation of therapeutic foam e.g.for the treatment of varicose veins. A pressurised vial contains a sclerosantliquid, e.g. polidocanol solution, and a sterile gas which is readily absorbedby the body, e.g. carbon dioxide, oxygen or a mixture of these gases. The vial isprovided either with a specialised stopper/seal into which a syringe nozzlemay be inserted or alternatively a septum seal which may be penetrated by a hypodermicneedle. The quantities of gas and liquid and the pressure in the vial are pre-setso that, on connection of a syringe to the vial, a predetermined volume of bothgas and liquid is transferred to the syringe, with the intention that the syringeis then used to make a foam by known means. The use of the vial ensures that the ratioof gas to liquid in the foam is standardised, and also provides a convenient wayof packaging the gas and liquid and of filling the syringe in a sterile manner.
