Definitions

  • the present invention refers to a device to be used for the therapeutic treatment of localised adiposity by ultrasound hydrolipoclasia.
  • Subcutaneous fat tissue is a tissue comprised of fibers and fat, lying between the derm (cutaneous layer located under the epidermis) and the muscle fascia. It constitutes the deepest layer of the skin, and establishes a weak bond between skin and inner organs covered thereby. It substantially performs the functions of protecting deeper tissues from any trauma, representing reserves of strength and limiting loss of heat, contributing to keep body temperature constant.
  • Adipose tissue is substantially formed by adipocyte cells. These are cells having the ability to synthesize and store triglycerides therein. Moreover, adipocyte cells (or simply “adipocytes”) tend to gather together into lobules, generally forming the so-called “panniculus adiposus”.
  • cellulite suggests a tissue pathology of inflammatory origin (in Italian medical language, the suffix ite indicates an inflammation).
  • cellulite substantially consists in an inflammation that affects the panniculus adiposus, causing an alteration of the latter. As a consequence of this alteration, it is determined an increase in the adipocyte volume, with the entailed transudation of liquids inside the intercellular spaces.
  • Cellulite mainly occurring in women, is an actual condition of tissues that does not merely manifest itself in an unaesthetic way, but can also cause cumbersome pains and anyhow constitute a general discomfort of the body. It, as it is known, causes skin surface to assume the characteristic "orange peel” or “mattress” appearance, exhibiting a series of more or less extended swellings. Zones most affected are the hips, buttocks and thighs. Description of the prior art
  • Numerous devices based on the principle of generation of pressure waves with a cavitational effect are currently available on the market. They substantially consist of an apparatus comprising a handle that is placed into contact with the body part to be treated. Said handle comprises a transducer of piezoelectric material that performs the transduction of an electric signal received thereby and emits ultrasound into the biological tissues treated. Said devices however, as witnessed by results directly observed on patients, yield mixed and often disappointing results. In fact, at best, patients attain only a draining of the liquids stagnating into tissues, liquids that therefore subsequently tend to be easily reintegrated. This is mostly due both to the frequency values of the ultrasound waves used, generally very high and of the order of MHz, and to the typology of handle used. Therefore, to date most of the times it is carried out only the absorption of liquids formed inside the panniculus adiposus.
  • Object of the present invention is to solve the above-mentioned drawbacks by providing a system as substantially described in claim 1.
  • the present invention by overcoming the mentioned problems of the known art, entails several evident advantages.
  • the device subject-matter of the present invention proposes the innovative use of ultrasound waves inside of a precise range of frequencies with values ranging from 35 KHz to 55 KHz, sufficiently low to create a localised action on adipocyte cells and allow a dissolving of the fat, yet such as to cause no damage to the surrounding tissues.
  • the precise range of low-frequency ultrasound employed by the device subject-matter of the present invention allows the production of a quantity of energy predetermined and targeted solely to adipose tissue.
  • ultrasound waves converge and concentrate on focalised zones, producing the immediate effect of rupture of adipocytes and emission of triglycerides, which are then quickly and naturally metabolised.
  • the range of frequencies used by the device results in the latter acting on adipose tissue only, thereby entailing a safe and effective fat-reducing and volume-decreasing action.
  • the results observed were immediate and measurable, even after only one treatment session (with a reduction of the treated area periphery of up to 2 cm).
  • figure 1 shows a block diagram of the device according to the present invention
  • figure 2 shows an elevation view of a preferred embodiment of the device subject-matter of the present invention
  • figure 2A depicts a detail not shown in figure 2
  • figure 3 shows a detail of the embodiment of the device subject-matter of the present invention
  • figure 4 shows a situation of use of the device subject-matter of the present invention.
  • FIG. 1 it schematizes the operation of a device 1 according to the present invention.
  • a voltage generator 2 that sends an electric signal to a transducer 5, which performs a transduction of said electric signal into an acoustic pressure signal at frequencies higher than the human audibility range (ultrasound).
  • the adjustment of said voltage generator 2 occurs by means of a programmable control and adjustment microprocessor unit 6 (microcontroller adjustment unit 6), in turn managed by the operator by interface means 7.
  • Said voltage generator and control unit are components well-known in the current state of the art, therefore hereinafter a detailed description thereof will be omitted.
  • FIG 2 a preferred embodiment of the device 1 subject-matter of the present invention is depicted by way of example and not for limitative purposes.
  • Said device 1 comprises a body 20, having at its base a carriage 21 in order to be easily transportable.
  • said control unit 6 and said voltage generator 2 (not shown in figure).
  • the electric signal produced by the voltage generator is sent, via connecting means 26, to a pair of twin handles 3.
  • said handles 3 are preferably arranged, when not in operation, on a pair of shelves 22, integral to said body 20.
  • said connecting means 26 is of wire type. The availability of a pair of handles can prove particularly convenient, as it provides the option of concomitantly treating two patients, or of concomitantly treating two different zones of the same patient.
  • human - machine interface means 7 comprising, by way of example and not for limitative purposes, a display and a keyboard.
  • an operator has the option of adjusting and programming the operation of the device 1 , e.g., by setting treatment times, power used, frequencies and emission times of the ultrasound produced.
  • Said interface means could also be made by more advanced technologies, e.g. by equipping said device 1 with a "touch - screen" type terminal.
  • said handle 3 has a first grip member 30 connected with a plate 4, made of conducting material and preferably of steel, having cylindrical shape.
  • Said steel plate 4 has an elevated thickness of height equal to about 1.5 cm.
  • the transducer 5 Directly on a free circular surface 31 of said steel plate 4 it is attached, in a concentric position, the transducer 5.
  • Said transducer 5, made of piezoelectric material, has it also a cylindrical shape and has a diameter smaller than the diameter of said circular surface 31.
  • the electric signal coming from said generator 2, sent on said steel plate 4 by said connecting means 26, establishes therein an electric field entailing a deformation of the piezoelectric transducer 5 attached thereon.
  • the properties of piezoelectric materials are well known in the literature; therefore the principles underlying their use in the art will be omitted, their practical implementation being within the reach of a person skilled in the art.
  • the device subject-matter of the present invention uses ultrasound with frequency values ranging from 35 kHz to 55 kHz.
  • frequency values ranging from 35 kHz to 55 kHz.
  • a frequency value close to 40 KHz is set.
  • a frequency value close to 50 KHz is set.
  • said grip member 30 comprises, at an edge thereof, a ring-shaped luminous indicator 9, active under conditions of use of the device. This provides an immediate reference for the operator, indicating the operativeness of the device itself.
  • FIG 4 it is depicted a situation of use of the device 1 subject-matter of the present invention.
  • the handle 3 brought into contact with a patient's skin at the piezoelectric transducer 5, attached onto the surface 31 of the steel plate 4.
  • Body parts most often subject of the therapy are abdomen, girdle, hips (a body part also known as “saddle bags"), inner thighs and the back of the knees.
  • the present invention has hereto been described with reference to a preferred embodiment thereof. It is understood that other embodiments might exist, all falling within the concept of the same invention, and all comprised within the protective scope of the claims hereinafter.
