Embodiment Construction

[0027] exist figure 1 The system according to the invention, represented schematically in , comprises a handpiece 1 for generating vapor by heating a liquid in order to diffuse the vapor through a conduit 2 connected to the handpiece, and a control unit 3 consisting of The mains is powered and itself electrically connected to the handpiece 1 for powering the handpiece. In a variant (not shown), the control unit 3 is powered by an accumulator or cells of an accumulator.

[0028] The handpiece 1 , shown schematically as a rectangle in the figures, actually has an ergonomic shape allowing it to be more easily held and manipulated by a medical practitioner holding it in his hand.

[0029] exist figure 1 In the configuration of , the containing device 4 is connected to the handpiece 1 to fill it with a liquid such as sterile water or even physiological serum, which should be heated to generate pressurized steam to be injected . as in figure 2 As can be seen in more detail in ...

Abstract

The invention concerns a handpiece for injecting vapour into an animal or human vessel in order to heat said vessel, said handpiece comprising means for generating vapour from a liquid such as water or physiological liquid and a connection member (8) for connection to a catheter (2) or a needle to be inserted into the vessel in order to inject the steam into same. The means for generating vapour comprise a heating reservoir (6, 7) intended to contain the liquid, and is provided with electrical heating means, for heating the liquid in order to vaporise same and produce a flow of vapour diffusing continuously via the connection member (8).

Description

[0001] The invention relates to a device ensuring thermal treatment of venous disorders by thermoregulatory injection of steam. Background technique [0002] More specifically, the present invention relates to devices for injecting vapors generated from liquids such as water or physiological fluids into human or animal vessels to heat them, usually causing them to self-close by constriction. In particular, when the steam reaches the inside of the vessel, the steam condenses and thus releases its sensible heat and its latent heat of condensation, which allows efficient heating of said vessel. [0003] Such treatments are performed, for example, to treat varicose veins, hemorrhoids, warts, etc.: the medical practitioner uses a catheter or even a needle connected to the handpiece. The handpiece has a heating device and is connected to a cold water injection unit capable of delivering a small amount of liquid with a volume of about 24 microliters in a pulsed manner similar to a pu...
