Abstract: A device is described for facilitating the preparation of therapeutic foam e.g. for the treatment of varicose veins. A pressurised vial contains a sclerosant liquid, e.g. polidocanol solution, and a sterile gas which is readily absorbed by the body, e.g. carbon dioxide, oxygen or a mixture of these gases. The vial is provided either with a specialised stopper/seal into which a syringe nozzle may be inserted or alternatively a septum seal which may be penetrated by a hypodermic needle. The quantities of gas and liquid and the pressure in the vial are pre-set so that, on connection of a syringe to the vial, a predetermined volume of both gas and liquid is transferred to the syringe, with the intention that the syringe is then used to make a foam by known means. The use of the vial ensures that the ratio of gas to liquid in the foam is standardised, and also provides a convenient way of packaging the gas and liquid and of filling the syringe in a sterile manner.

Abstract: A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.
