<p>The device includes a container (1) in which the sclerosing liquid is deposited, in addition to connecting means (18) to a propellant gas source. Said container is hermetically closed by a head piece (2) in which a small diameter probe tube (3) is inserted to reduce pressure, said tube extending inside the container (1) and being closed by a valve (7, 8, 10, 11, 12 and 13) whose actuation causes the outflow of the foamed sclerosing agent through an outlet (14) provided in the head piece (2) as a result of the propellant gas.</p> |
