DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention is related to an apparatus for microdermabrasion by means of a jet of a mixture of air/reducing substances, and the related handle. The present invention is used in aesthetics and/or dermatology, and concerns in particular an apparatus, and the related handle, for microdermabrasion, so that a jet of reducing substances is applied on human tissue, in particular a jet of corundum crystals (Al.sub.2 O.sub.3). The present invention can be used for all applications of traditional microdermabrasion, for example:
Furthermore, the present apparatus can also be conveniently used in the trichologic field (e.g. peeling of the scalp).
BACKGROUND ART
The known apparatuses for microdermabrasion have three remarkable disadvantages: remove; substances, wherein said obstruction causes blockage in the apparatus; and with particles of abraded tissue, which can be infectious.
The European patent application EP-A-0 324 448 (L.I.C.A. of Rosso & C. Snc) and the European patent application EP-A-O 318 042 (Molinari et al.) concern two apparatuses for the micro-abrasion of human epidermis. These devices do not solve either the aforesaid particular hygienic problems or those concerning the obstruction of the circuits. Furthermore, with regard to the handle described in EP-A-0 318 042 (Molinari et al.), it must be specified that it is very expensive for its structure and material. Also apparatuses using monobloc handles made of a glassy material (in particular tempered Pyrex.TM. have been developed. In this case the handles do not show particular problems concerning obstruction or sterilization, but, because of the particular material they are made of, they are rapidly worn out, thus becoming thinner, so that they could even hurt the patients. All three apparatuses require the pouring out of the crystals, both in the loading and in the unloading phase. Therefore there could be a dispersion of crystals in the environment. If these crystals were used crystals mixed with particles of abraded tissue, there would be a dispersion of potentially infecting material. Furthermore U.S. Pat. No. 3,878,962 (Holbrook et al.) illustrates an improved bottle which can be used for collecting the body fluids of patients in hospital operating rooms. In this bottle the cartridge is closed by means of a quick lock. However, nowhere in U.S. Pat. No. 3,878,962 is it specified that the cartridge filled with unused liquid can be utilized in the following treatment to contain the used liquid.
DISCLOSURE OF INVENTION
The apparatus for microdermabrasion of the present invention was designed according to innovative principles in order to overcome all difficulties which can arise by performing dermabrasion or abrasion of the scalp. The operator using said apparatus is provided with recharging cartridges, each of them containing an amount of corundum which is sufficient for several operations. Once the cartridge is empty, the operator must replace it with a new one by moving the special locking means of the empty cartridge to the full one, and he must perform the opposite procedure with the cartridge containing the used corundum. In this way the cartridge full of dirty crystals, namely mixed with particles of abraded tissue which is potentially infecting, can be sent to the waste disposal without pouring out the crystals, which always causes a certain dispersion of the crystals in the environment, with the concomitant spreading of abraded tissue. With the apparatus of the present invention, the whole loading and unloading of crystals is performed in a few seconds, easily and without spreading the used crystals in the environment. Furthermore, the recharging cartridges can be sterilized, if necessary (previously sterilized cartridge or corundum). The owners of the apparatus can buy the corundum cartridges at the same price as loose corundum. Furthermore, if it were necessary for hygienic reasons, it would be possible to get rid of the recovery cartridges, since they are very cheap (disposable use). The particular handle, which i
