DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates in general to apparatus for making micro-abrasions, particularly for cosmetic and/or therapeutic treatment of human tissue (the removal of scars and stretch marks), as well as for the treatment of hides and similar adherent and non-transpiring materials.
More particularly, the invention is concerned with apparatus of the type including a handle having an inlet passage and an outlet passage which communicate with an aperture intended to be positioned on the surface to be treated, and means for the metered supply of reducing substances in a pneumatic carrier to the aperture of the handle.
SUMMARY OF THE INVENTION
The object of the present invention is to produce apparatus of the type defined above, which is simple and cheap to produce and is very effective in operation.
According to the invention, this object is achieved by virtue of the fact that the means for supplying the reducing substances comprise only a vacuum source connected to the outlet passage of the handle for drawing the reducing substances towards the aperture of the handle through the inlet passage thereof.
The aperture of the handle preferably has a configuration which can be adapted substantially sealingly to the surface to be treated.
According to one preferred embodiment of the invention, the inlet passage of the handle is connected to a supply container for the reducing substances which has in its base a plurality of air-intake apertures with associated regulator valve means, and the outlet passage of the handle is connected to a discharge container which has an outlet aperture connected to a vacuum pump.
Filter members are conveniently associated with the intake apertures of the supply container for achieving a shaking up of the reducing substances by means of the valve and regulating means.
Conveniently, the supply container is provided with electrical means for heating the reducing substances.
BRIEF DESCRIPTION OF THE DRAWINGS
Further characteristics and advantages of the present invention will become clear from the detailed description which follows with reference to the appended drawing, provided by way of non-limiting example which shows apparatus for making micro-abrasions according to the invention, in diagrammatic form.
DETAILED DESCRIPTION OF THE DRAWINGS
With reference to the drawing, a handle, schematically indicated 1, normally has anatomically-shaped grip and is provided at one end with an interchangeable head 2 which can assume shapes different from that illustrated, in dependence on the use for which the apparatus is intended. In this instance, the head 2 has an inclined front wall 3 forming an aperture 4 which is adapted to be positioned, in use, on the surface 30 to be treated as shown in the drawing.
The aperture 4 communicates at one side with an inlet passage 5 and at the opposite side with an outlet passage 6, and these are connected to respective tubes 7, 8 connected to the handle 1. The inclination of the wall 3, and hence of the aperture 4, to the inlet passage 5 is of the order of 45.degree.. The inlet passage is oriented substantially perpendicular to the outlet passage.
The tube 8 is connected through an inlet connector 9 to a recovery container 10 having an outlet connector 11 with an associated filter member 12. The outlet connector 11 is connected to an intake tube 13 which is connected to an electric vacuum pump 15 through a vacuum-gauge 14 with a regulator.
The tube 7 is connected to a base connector 16 of a supply container 17 into which a quantity of reducing substances S, normally constituted by abrasive particles of various sizes, is introduced. At rest, the reducing substances S occupy the lower region of the container 17, beneath the mouth of an intake tube 18 which communicates with the base connector 16 and has a hole 28 at its lower end. According to a variant, not illustrated, the intake tube 18 may open outside the container 17.
A passage 19 is situated in the base of the container 17 and communicates with the atmosphere throug
