DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an apparatus for heat therapy by inhalation.
The work of Professor Andre Lwoff has shown that the development of a virus depends on the temperature, which can be characterised in three zones: optimal, infra- and supra-optimal. At supra-optimal temperatures, the viral genetic material is destroyed by the lysozomal enzymes which are prematurely released, and the development of the virus is blocked. This work forms the subject of a report to the Academie des Sciences de Paris (Academy of Sciences of Paris), vol. 291 (8 Dec. 1980) series D-957.
On the basis of this work, a Franco-Israeli team of research workers at the Weizmann and Pasteur Institutes developed a heat therapy of infectious coryza and persistent allergic rhinitis. For this purpose, a so-called "rhinotherme" apparatus was designed and formed the subject of patent application FR No. 2,399,851. The clinical trials based on this heat therapy enabled suspension of the symptoms of the disease to be achieved for a long period in a large percentage of the patients, especially in patients suffering from persistent rhinitis which resisted any other treatments.
Although these results are encouraging, the complexity and cost of the apparatus developed for this purpose make this therapy inaccessible to the general public, so that this simple and wholly natural therapy is, in practice, only used at the very most in the hospital situation. Now it is clear that an apparatus of simpler design, sold at a reasonable price, would naturally find its place in any family medicine cabinet in the same way as electric tooth-brushes or other apparatus for care of the gums. Widespread distribution of such an apparatus could have beneficial effects both on health insurance resources and on the economy generally, taking account of the frequency of these viral complaints which, during some winters, cause the loss of a large number of working days.
The object of the present invention is, specifically, an apparatus for heat therapy by inhalation which is simple in design and safe in operation, the price of which makes it suitable as an apparatus for home use.
For this purpose, the present invention has as its subject an apparatus for heat therapy by inhalation according to claim 1.
The simplicity of this apparatus results from its design, which does not involve any moving parts, the motive component consisting either of steam under pressure which results from heating water and feeds a venturi, or of the partial vacuum which results from breathing in. Since the operating parameters are essentially constant, the temperature of the air/steam mixture inhaled can be fixed by the design.
The attached drawing show diagrammatically, and by way of example, two embodiments and a variant of the apparatus which is the subject of the present invention.
FIG. 1 is a sectional view in elevation of one of these embodiments.
FIG. 2 is a partial view of a variant in elevation, partially cut away.
FIG. 3 is a diagram of the second embodiment.
The apparatus illustrated in FIG. 1 incorporates an enclosure 1 formed by a cylindrical container 2 which is closed by a stopper 3 screwed onto this container. An O-ring sealing gasket 4 situated in a groove 5 made in the side of this stopper 3 serves to effect the sealing between the stopper 3 and the cylindrical container 2.
The wall of the container 2 incorporates an inner stainless steel part 6 surrounded by a thermally insulating layer 7 and an external envelope 8 which can, for example, be of plastic.
The stopper 3 carries, concentric with its axis of revolution, two coaxial tubes 9 and 10 made of stainless steel, non-corroding alloy or platinised titanium, for example. These tubes are connected by two conductors, 11 and 12 respectively, to an alternating current source S, and have perforations, 9a and 10a respectively, at the top. These tubes, which act as electrodes for heating undistilled water, can obviously be replaced by two simple rods (not shown) which advantageously terminate at the bottom end in two spheres or
