Definitions
- the present invention relates to a device for localized application of cold during a traumatic treatment of the dermis such as dermography or hair removal, or even injections of products for restructuring the skin.
- Such pigments are chosen not only as a function of the desired aesthetic effect but also of the desired duration of this so-called permanent effect which varies according to the habits of the subject such as the durations of exposure to the sun, the sensitivity of the skin, the speed cell regeneration or implantation depth.
- Dermography is similar to tattooing but the penetration depth of the pigments in the dermis is generally lower, from 1 to 2 millimeters, if only because of the places of application which leave little space such as the eye area or the lips.
- Permanent makeup can be practiced on any person, man or woman, of any age. In addition, it provides certain benefits for many types of population and to varying degrees such as sports people who do not see makeup flowing during the practice of their activities, people who have vision problems since the application specifies products especially on the contours is deleted, people with defects to be corrected such as scars, after-effects of accident or surgical intervention, or burns.
- Dermography devices are of different types and are distributed commercially, regardless of the mechanism used, vibrating or connecting rod. The goal is to give a needle or several needles simultaneously a translational movement to penetrate the dermis and simultaneously implant the pigments in the pricked area.
- anesthetics to inject are even more delicate to handle and require the recourse to a practitioner such as a dentist for the interventions on the face, which is not a solution. acceptable.
- Analgesics or sedatives are prescribed only by doctors and must be administered beforehand, which implies certain additional constraints.
- the present invention provides a device for localized cold application which overcomes the drawbacks of the means used to date and which provides an effective and controlled anesthetic effect, which is easy to handle, which is precise in temperature as in contour application, and which limits post-intervention trauma.
- FIGS. 2A and 2B different heads intended to be adapted on this device
- Figure 1 there is shown the complete device as it can be used to provide an anesthetic effect during the production of dermographies using suitable devices.
- This device comprises a handle 1 0 and a body 1 2.
- This body comprises internal elements and a housing provided with slots 14 for air circulation, and comprising a working head 1 6 on one of its faces.
- the handle has no technical particularities except to allow a good grip of the device. It also allows guiding of the 1 8 wired power supply and control links of the various elements.
- the body 1 2 and its content are detailed in Figure 3 and include a head part 1 6 of work, a support housing 20, portable, and means 22 for generating frigories.
- the head part 1 6 of work comprises an end piece 24 of application having a given profile and means 26 for removably fixing this end piece on the support housing 20.
- These nozzles have different configurations, in this case the one shown has a small and relatively narrow surface, also visible in FIG. 2A while other variants, such as that of FIG. 2B, make it possible to cover larger surfaces, disc-shaped.
- the removable fastening means 26 advantageously consist of a cover 28, the peripheral flange 30 of which allows snap-fastening or screwing on the support housing 20.
- This cover has in its center a cutout 32 to allow the passage of the tip while a collar 34, integral with this same tip, retains it.
- This application nozzle is designed to come into contact with an applicator 36 which is a metal plate ensuring the transmission of the heat fluxes.
- This applicator also supports a temperature sensor 38 which is integrated into the thickness itself so as to limit the measurement drifts.
- This applicator 36 is in direct contact with the means 22 for generating frigories.
- modules 40 with Peltier effect include quite advantageously a module 40 with Peltier effect.
- a module generally comprises two ceramic plates, between which is disposed a succession of different positive and negative junctions, semiconductor type, connected in series.
- Such modules are commercially available.
- this module is connected to a direct current power supply, the current delivered makes it possible to generate a heat transfer from one face to the other so that one of the faces becomes cold while the other heats up.
- the cold face is oriented towards the applicator. In order to allow an even more satisfactory exchange at the interface, it is useful to provide for the deposition of a thin layer 42 of thermal grease on either side of this module.
- the heat which is produced on the upper face of the module must imperatively be removed, on the one hand, so as not to destroy the housing and, on the other hand, in order to improve the efficiency of this module.
- a finned radiator 44 is provided, the base 46 of which is in intimate contact with the hot face of the Peltier module.
- the fins provide air cooling but the amount of heat generated by the module, confined in a housing like the housing 1 0 of this device could cause an excessive increase in temperature.
- an extension 48 is provided which makes it possible to house a heat extractor 50 with blades, surmounted by a grid 52.
- This same extractor can also be provided with a safety device of known type, which interrupts operation in the event of overflow a temperature threshold.
- the operation of the device according to the present invention is now described in its direct application to dermography.
- the person to be dermographed can take over the device if they wish.
- the Peltier module ensures the production of frigories on the face in contact with the applicator 36, through the layer 42 of thermal grease.
- the frigories are transmitted by conduction to the nozzle 24 which, preferably metallic, conducts heat flows very well.
- the temperature sensor 38 makes it possible to control the quantity of frigories generated by the Peltier module, so that, by means of an auxiliary console with a programmable microprocessor, it is simple to provide automatic regulation of the temperature with respect to a set value or with respect to a given curve, after stabilization.
- the application tip 24 remains regulated at a temperature within a very limited range. This temperature is adjusted according to the sensitivity of the person, the characteristics of the dermis, the mode and means of dermography, in particular.
- the device At the end of the dermography session, it is possible to leave the device applied for a longer period so as to avoid the after-effects as much as possible and the temperature can also be modified.
- the device provides comfort for the person but also allows the practitioner to dermograph in the best conditions.
- the cold in addition to the anesthetic effect, ensures a contraction of the lymphatic channels and other venules, so that there is a significant limitation of the formation of edemas and hematomas, knowing however that surface flow is about him inevitable and necessary for the implantation of pigments.
- the tip should be adjusted, which is achieved extremely quickly by snap-fastening or screwing.
- the heat produced it is emitted in the form of calorific radiations by the radiator 44, radiations which are conveyed by the air flow put into circulation by the extractor 50, the grid 52 having merely a protective role d '' access to the extractor blades.
- thermometer In the event of a malfunction, a safety thermometer of known type ensures the supply of power to the Peltier module, while leaving the extractor in service if necessary to ensure faster cooling.
- the console associated with a microprocessor which controls the temperature and the operation can also integrate a frequency converter to also control the operation dermography means and therefore the frequency and / or the power of penetration of the needle into the dermis.
- the Peltier module is entirely suitable because it makes it possible to obtain frigories in a very short time, it is compact and light, so it can be integrated into the device, without the need for an auxiliary cold production plant.
- the Peltier effect module selected for the generation of frigories is the preferred embodiment for its compactness, its speed of commissioning, its low inertia but any other means of production of frigories can be envisaged as long as it is possible. to house it in a handy support case.
