Definitions

  • the invention relates to a light ray unit for diagnosis and treatment of skin problems.
  • exposing the skin to light beams of varied intensities and durations data can be obtained relating to the state and characteristics of the skin, which data can then be used for diagnostic purposes.
  • telangiectases fine capillary dilation phenomena
  • Apparatus are commercially available which are equipped with a lamp commonly used for flash light signals (for example sirens with flash lamps for emergency call vehicles), but are more powerful because they have not only a visual effect but also a production of heat.
  • a lamp commonly used for flash light signals for example sirens with flash lamps for emergency call vehicles
  • the lamp is mounted internally of a mirrored parabola which has the effect of converging the light towards a precisely-defined point on the skin.
  • the assembly is inserted in a casing provided with a switch for activating the emission of a light radiation.
  • the lamp emits radiations having a very broad range of wave lengths going from ultraviolet to infrared, and for this reason a filter is interposed between the lamp and the skin, so that only the desired wavelengths can pass. This is because each pathology requires a treatment involving a well-defined wavelength.
  • Light pulse apparatus on the commercial market are manually programmed by means of buttons on the control panel, where the power emitted by the lamp is regulated.
  • an air-intake cooling organ having a pipe which conducts the heat of the lamp towards the control panel.
  • the light pulse has a large treatment area due to the lamp size; for this reason the apparatus comes complete with reduction masks for the treatment area, which are simple covers with slits of various sizes.
  • Each cover when positioned in front of the lamp, causes the light to issue only through the slit, so that small areas can be treated.
  • These reducers are separate from the casing and can easily get lost.
  • Apparatus of this type are normally used by medical personnel (for diagnosis and treatment) and by operatives working in the aesthetic treatment field (for various low-invasive treatments such as, for example, depilation).
  • the technical aim of the present invention is to obviate the above-cited drawbacks and to satisfy the specified needs, i.e. supplying a light-ray unit for diagnosis and treatment which thanks to special use configurations can carry out all of the functions of diagnosis and treatment of the skin, while medical-type functions are made unavailable for use in units destined for beauty centres.
  • Another advantageous aim of the invention is to provide a unit with reduction masks for the treatment area which masks are integrated with the casing and not separate there-from.
  • a further positive aim of the invention is to provide a unit in which the cooling system is very efficient and not influenced by the maintenance characteristics.
  • a still further aim of the present invention is to provide a simple structure, relatively easy to set up, reliable in use and efficient in functioning, as well as having relatively low costs.

  • the unit 1 is constituted by a casing 2 connected by multipolar cable to a control processor.
  • the casing 2 is elongate with smooth connected surfaces, with through-slots 5 afforded in its posterior side, above a hole provided for entrance of a cable 3.
  • buttons 6 (6a, 6b) are present, which have the task of selectively activating the diagnostic operation (6a) or the therapeutic button (6b) of the unit 1.
  • a cabled group 7 provided with a plurality of f ontal openings 8 is situated.
  • the group 7 is a block with a flat bottom 9 and with lateral walls delimited by two respective masks 10 made of a material that is not transparent to light radiation and which exhibits small slits 11.
  • the filter 12 superiorly exhibits a transparent screen, the filter 12 having a rectangular area with sides measuring respectively 50 and 30 mm.
  • the filter 12 can be made of materials such as glass, quartz, sapphire, but also ceramic, plastic or other types having filtering characteristics to block the light radiation.
  • a phototype sensor 13 is also located above the group 7.
  • the group 7 exhibits plugs 14 for connection to the casing 2, to establish an electric connection with the socket 14a.
  • Posteriorly on the group 7 are a number of plugs 14 for connection to the casing 2, which electrically connect to the connection socket 14a.
  • the group 7 is constituted by a reflecting parabola 1, in lateral guides 16 of which there are masks 10 that are free to slide along a plane thereof up into a position in which they reduce the treatment surface.
  • the patient can be subjected to a light radiation of wavelengths varying between 1 and 2000 nanometres.
  • a cooling turbine 20 is installed longitudinally and located internally of and at the back of the casing 2. When the turbine 20 is operating, it sucks air through the holes 5 and entrains it towards a conduit 21 (delimited between the bottom 9 of the group 7 and the zone surrounding the lamp 18) towards a frontal outlet constituted by the opening 8.
  • the whole group 7 is removable and can be substituted with other groups having different filters, suitable for performing different treatments.
  • the phototype sensor 13 is a very important accessory as it serves to reveal the typ of skin under treatment at any given time.
  • Various types of skin exist, and are classified under the Fitzpatrick scale, which defines the reaction of a skin subjected to light rays, such as, for example, the sun's rays.
  • This classification defines six types of skin: a first type which always burns; a second type which sometimes burns; a third type which sometimes burns and sometimes tans; a fourth type which tans and sometimes burns; a sixth type which tans but does not burn.
  • the phototype sensor 13 enables a diagnosis of the patient's skin, defining which group he or she belongs to so that the correct treatment can be applied.
  • the phototype sensor 13 is formed by four main components: a led light 22, a photodiode 23, a start button 6a and an electronic control apparatus described in the block diagram of figure 11.
  • the casing 2 contains a generator 24 of electric current or voltage, which supplies a stabilizer circuit 25 for the work point (possibly with temperature compensation), the led light 22 (which can be replaced by any infrared or visible band radiation source, possibly controlled at a predetermined frequency), connected for stabilisation of the circuit 25, a second stabiliser circuit 26 (possibly with temperature compensation) and the photodiode 23 (which can be substituted by any infrared or visible band receiver), connected for stabilising the circuit 26.
  • the outputs of the circuit 26 and the photodiode 23 lead to the inputs of a circuit 27 for treating the analog signal which then transfers the signal f om its output to the control processor through the cable 3.
  • the phototype sensor 13 is positioned close to the lamp 18 but can also be positioned in other places, or separate from the group 7.
  • a temperature sensor is inserted in the group 7 and is connected to the control and activation processor 4 of the lamp 18, which makes sure that the lamp 18 does not exceed a predetermined temperature which might damage the group 7 and/or burn the skin of the patient undergoing treatment.
  • the temperature sensor can be electronic, electric, electromechanical or of any type having these functions.
  • the casing 2 contains a generator 28 of the reference electric power, which supplies a stabiliser circuit 29 of the work point (with a temperature compensation faculty) and a temperature sensor 30 (for example an electrical photoresistance).
  • the outputs of the circuit 29 and the sensor 30 lead to the inputs of a circuit 31 for treatment of the analog signal (installed in the body containing the processor 4 through the cable 3) which then transfers the signal from the output to the control processor 4 and to safety devices which are not shown in the figures of the drawings.
  • Each group 7 differs in the type of filter 12 mounted, and for purposes of recognition the group 7 is provided with an electronic recognition apparatus.
  • This recognition apparatus is an electric circuit positioned internally of the group 7 which when the filter is mounted sends a signal to the control processor which in turn sends to the display 32 of a monitoring and control processor 33 an indication of the type of filter 12 present on the casing 2. Since the filter 12 is an integral part of the group 7, the problem of recognition of the filter 12 is reduced to the problem of recognition of the electrical circuit of the group 7 on which the filter 12 is installed.
  • the filter 12 sensor comprises a generator 34 of the reference electrical power supplying a generator 35 of the analog current, the level of which identifies the type of filter (for example the electrical resistance).
  • a circuit 36 receives input from the output of the generator 35, and adapts and compares the electric power (if the power belongs to a first value set it means that the filter 12 is of the first type ). The comparison can be performed by suitable measuring instruments and transmitted digitally to the processor 4 or realised directly by the processor
  • the invention functions as follows. Once the treatment type for the patient is known, a suitable type of group 7 is chosen and inserted in the casing 3 by sliding the bottom 9 into the seating and the plugs 14 into the socket 14a. The filter 12 sensor will bring up the filter type on the display 32.
  • the operator selects the most suitable programme (following the indications that appear on the display 32 determined by the treatment programs memorised in the processor 4 which operates a control on all the operations the operator carries out) and starts treatment with the button 6b keeping the casing 2 oriented with the lamp 18 facing the portion of the skin to be treated.
  • the mask 10 can be removed from the guide 16 and arranged in front of the filter 12 (following the sequence indicated in figures 4, 5 and 6).
  • the temperature of the lamp 18 is constantly monitored by the temperature sensor 30 which sends a signal that is proportionate to the lamp temperature to the processor 4 which regulates the duration and frequency of the successive flashes in order to avoid over-heating.
  • the processor 4 inhibits the lamp 18 operation.
  • the cooling turbine 20 is in action and maintains the lamp 18 temperature low.
  • the lamp 18 cooling can be obtained by realising a hydraulic circuit for circulation of a fluid in the casing 2 close to the lamp 18, connected to a refrigerator for keeping the fluid at a low temperature.
  • the refrigerator can be inserted internally of the body containing the processor 4 or can be a separate body.
  • the processor 33 can be connected to the processor 4 by a cable or can be cordless. This is extremely advantages if the operator has to perform treatments on the patients which involve special positions. The operator continuously has the display 32 in front of him or her so that all treatment parameters are clearly visible.
