Description

The invention relates to a device for skin treatment, according to the preamble of claim 1, and a method for cosmetic skin treatment.

Skin treatment devices have been around for a long time, where an internal pressure generator creates a suction pressure field is built up on the treatment head to be acting skin area is applied. Such devices who used and effect in cosmetics salons, for example a rapid change, for example at 50 Hz between pressurized air and skin suction, so that this massages and thereby, for example, the through bleeding or lymphatic drainage improved becomes.

The invention has for its object a device for To create skin treatment that is a skin treatment with improved cosmetic or therapeutic we can achieve kung.

This object is achieved with those mentioned in claim 1 Features resolved.

Advantageous embodiments of the invention are in the Un claims specified.

Furthermore, the invention provides a method for verbs Serten cosmetic skin treatment created.  

In the invention is thus simultaneously with the generation of the suction pressure field a temperature treatment of the skin carried out. This simultaneous action of the suction Pressure field and the temperature change through which u. a. the Degree of opening of the skin pores is controllable, z. B. control the depth effect of the treatment more precisely.

So it is, for example, when applying cosmetic or therapeutic treatment agents such as creams or Ointments possible, the skin before or at the same time as opening bring the treatment agent to the suction pressure field and exposed to an increase in temperature at the same time. Here was the advantageous effect observed that the suction Pressure field in connection with that caused by the temperature increase open skin pores a deep cleaning of the same is achieved. The treatment agent to be applied can thus undisturbed on the skin cleaned so deeply with correspondingly high cosmetic or therapeutic Affect efficiency. The treatment agent is also through the suction pressure field deep into the due to the tempera Door increase driven open pores, whereby the Effectiveness of the applied agent increased even further.

Especially if after applying the treatment agent and its incorporation into the skin under appropriate Temperature increase followed by cold treatment of the skin is carried out, the skin pores close immediately like and consequently include the Be entered in the pores means of action, so that this firmly in the upper area of the Skin is anchored and its effect undisturbed in full catch can unfold.

Of course, it is also possible to use only one ge joint suction-pressure treatment and temperature treatment perform without any external treatment such as applying ointments or the like. Here  can, as already mentioned, a thorough cleaning the skin and also a deep impact of the suction pressure field achieve with open pores, so that an improved cosmetic effect with regard to skin massage and also the elimination of pent-up lymph fluid.

The device according to the invention also surprisingly appeared the treatment of headaches as well suited to those through the simultaneous action of the suction pressure field and the temperature treatment, preferably a cold storage treatment and / or alternating heating and cooling action, a faster resolution of the headache had drawn.

The device according to the invention was also shown in tests extremely effective in cellulite treatment. Farther is the possibility given by the device according to the invention ten, for example also creams or ointments to ap effectively plicate that relatively tough at normal temperatures and are not effectively absorbed through the skin can. Such treatment agents can by the device applied heat are melted and then penetrate this highly liquefied form under the influence of the Suction pressure field effectively into the skin.

In a preferred embodiment, the treatment head is included two treatment areas, one of which is ge cools and the other is heated. By the simultaneous Providing a heating surface and a cooling surface can extremely quickly between heat treatment and cold treatment skin. There are no delays waiting times can be waited for, as is the case when using only egg ner area is the case, the temperature of which in a broad order catch is variable and from cold to warm temperature and vice versa must be brought in when treating a change in temperature is intended. The tem  temperature treatment with suitable cool or warm tempera structures can be carried out very quickly.

The device according to the invention is also characterized by extremely easy to use due to the treatment head not only to generate the suction pressure field, but also is used for temperature treatment, d. H. with a single Ge advises both types of treatment to be carried out simultaneously can. In contrast, treatment would be with a treatment head building up a suction pressure field and another temperature treatment head a constant change sel of the treatment heads necessary, what with appropriate Operating effort is connected. In addition, there would be none simultaneous influence of suction pressure field and temperature treatment attainable.

A particularly cheap and easy handling of the treatment lungskopf is offered by its T-shaped shape, so that it has a hammer shape. The two treatment areas Chen are then preferred on the two end faces of the transverse arranged end section, while the long mitt lere leg serves as a handle. The treatment head leaves thus rotate in a very simple manner and thereby ent neither the hot or the cold side as needed on the Apply skin treatment site. This is an efficient, one-handed use achieved. The treatment also collapses surfaces of the treatment head accordingly, so that it is very simple, the desired treatment area of the Ge in contact with the skin area to be treated bring. The arrangement of the two on different tem treatment areas lying on opposite sides Positions also leads to good thermal decoupling development between the treatment areas, so that the effect not through unnecessary cooling of the hot side or Warming up the cold side is affected.  

The outlet openings for the suction pressure field are preferred directly in one of the treatment areas, preferably the heated treatment area. This will a simultaneous effect of the suction pressure field and the Heat treatment in the treatment area is simple made. Alternatively, both treatments can also be used areas with outlet openings for the suction pressure field verse hen be or the outlet openings can only be arranged on the cold side of the treatment head. Last Other options are particularly useful if e.g. B. applying cold treatment agents are applied.

In an advantageous embodiment, the heating and / or cooling device between the treatment surfaces of the treatment arranged head so that compact structure is achieved and the heat and / or cold generated as close as possible to the Be action areas is generated so that by heat power losses caused extremely low can be.

A Peltier element is preferably used, which simultaneous generation of cold and heat on his at the sides with an extremely simple, compact structure and good Controllability enables. The Peltier-Ele excitement only extremely weak tension, so that too the electrical safety of the device is very high and no special electrical shielding measures on the Be action head must be taken.

In an advantageous embodiment, the device has a sta tional device part, which has a connecting line arrangement voltage is connected to the treatment head. The treatment head can thus be used as a handpiece that is good and is easy to use and operate almost unhindered leaves. Also, there are no components for the Er in the handpiece  generation of the suction and pressure field, son this can be done via the connecting line arrangement respectively.

In a preferred embodiment, the treatment head has a plastic handle with an extension middle area. This middle area can be the same timely both for holding the treatment areas tra ing, good heat-conducting, preferably metallic parts serve as well as the required thermal separation between provide these parts.

An effective thermal decoupling with good, stable The biler mounting function is made using plastic Holders to fix the treatment areas the metallic parts. These are preferably Plastic brackets formed by plastic screws, which, preferably sunk, on a metallic head part concern and in the others, through the middle extender through the handle area are screwed in. In order to the treatment head can also be easily replaced if necessary disassemble. The heat transfer between the two metalli but headboards is still very small, because that's art material is poorly heat-conducting and therefore no heat coupling causes.

In a preferred embodiment, the elongated mitt has handle area still has the further function of accommodating the Peltier element and holds it in such a way that good warmth Tender contact between the metallic headboards and the both, assuming different temperatures when power is supplied end of the Peltier element is guaranteed.

The one is preferably a metallic head part with a through openings for the suction pressure field a removable front carrying the treatment area  Head area. This facilitates complete cleaning of the removable head area including the passage openings so that the treatment head is always completely hy gienisch cleaned can be kept. The removable one Head area can be in good heat conductive connection via a screw connection with the lead on the treatment head Connect the head section. Alternatively, a Ba be used for the jonet lock, with good heat-conducting Connection must be ensured.

It is preferred to treat the treatment area (s) with a neutra len coating preferably made of precious metal. Here by ensuring that none during treatment allergic or other undesirable skin reaction be called.

Especially if the two headboards are made entirely of metal are, they have a relatively high weight. This brings the advantage that the treatment area due to Dead weight with a relatively large, but not uncomfortable There may be pressure on the skin area to be treated, if it is more or less upwards. Of the the user holding the treatment head in his hand must be there hardly any additional pressure force, so that also relatively fatigue-free for longer periods of use can be worked. Bring the metallic headboards also considerable heat storage capacity, so that the jewei current temperature of the head part relatively stable and fluctuates only to a small extent, even when the device is inserted, d. H. in contact with the skin brought.

The use of the Peltier element as a heating and / or cooling device direction also offers the further advantage that by a multiple polarity reversal of the voltage supply of the Peltier element one turn of the heat and cold releasing side possible  is. So if, for example, the warm side is normally is provided with the nozzles for the suction pressure field by reversing the polarity of the voltage supply of the Peltier element now the previously warm side are cooled, so that now a combination of the suction pressure field with the cold treatment development surface of the treatment head.

In an advantageous embodiment, the device is open area to which the treatment head applies Can be put away when not in use. So that is the treat can always be stored in a defined manner.

The receiving area is preferably provided with a cooling plate on which the treatment head with its heated Treatment area can be placed. This will this cooled, so that an excessive heating of the treatment head when not in use, but still running Heating device is avoided. For effective heat dissipation A fan is preferably present from the cooling plate, which can advantageously be regulated by a control circuit. The cooling effect of the heat sink can thus be regulated, so that the treatment head temperature at a desired value ge can be held.

The heat sink can be used to complete the control be provided with a temperature sensor with the tax circuit is connected. The control circuit then regulates the Fan, preferably its speed, such that the cooling sheet metal in its surface temperature, especially in loading rich the support of the treatment head essentially kon remains constant. This temperature is preferably above the skin temperature, preferably at about 38 to 40 ° C. The cold side of the treatment head then it is clearly below half the skin temperature, for example at approx. 4 ° to 8 ° C.  

In an advantageous embodiment, the fan is also after Turning off the Peltier element kept in operation so that - with the treatment head on - the warm one Stored heat can still be extracted and thus excessive heating due to the internal storage heat is prevented. The treatment head is now closed at least within the first time after switching off the Pel tier elements with controlled temperature on its warm side usable.

The invention also provides a cosmetic method Skin treatment created, at the same time with the suction pressure field generated by the treatment head the skin exposed to an increase and / or decrease in temperature becomes. Due to the combinatorial effect of Temperaturge controlled skin reaction, especially the pore opening or Closure, and the air-suction pressure field can be ef achieve effective cleansing of the skin. Preferably at this cosmetic treatment is a cosmetic treatment medium, preferably applied in ointment or cream form. The skin can first be heated so that under the combinatorial effect of the temperature increase and the Suction pressure field the treatment agent in its flowable speed is increased and penetrate into the open pores into which it is deep due to the effect of the suction pressure field is pushed into it. The skin can be removed immediately afterwards cool down suddenly by turning over the treatment head, so that the pores close and open in the pores treatment means taken as a depot at least remains stored at short notice.

The invention is illustrated below by means of an embodiment game described with reference to the drawings ben. Show it:  

Fig. 1 is a schematic external view of an example of exporting approximately the inventive device,

Fig. 2 is an exploded view of the treatment head, and

Fig. 3 shows a temperature control section for controlled cooling of the treatment head.

In Fig. 1, an embodiment of the skin treatment device according to the invention in the form of a suction-pressure massage device with simultaneous application of heat and / or cold ge is shown. The skin treatment device has a stationary part 1 , which is portable, but is usually held stationary during use of the skin treatment device. The stationary part 1 forms a control panel and is connected via a connecting line arrangement 3 to a treatment head 2 , which has a hammer-shaped or T-shaped configuration.

The connecting line arrangement consists of an air hose 4 and an electric cable 5th The air hose 4 is on the side of the control panel 1 with a generator in this angeord NEN for generating pressure suction impulses which, for example, has a movable membrane through which alternating air pressure impulses and air suction impulses with a frequency of 50 Hz, for example be generated. Such suction-pressure generators are known.

For the infinitely variable regulation of the strength of the suction pressure field, there is a control element in the form of a rotary knob 6 which can be actuated by the user and which acts via intermediate elements on the generator arranged in the control panel 1 or the control circuit for controlling the amplitude which also controls the generator and is not shown.

The control panel 1 is also provided with an on / off switch 7 , by means of which the heating and cooling device of the device can be switched on and off. Further, the STEU erpult provided 1 with a socket 1, in which a plug 8 of the electric cable is inserted. 5 For the polarity reversal of the supply of the heating and / or cooling device, a polarity switch ( not shown) can also be present on the control panel 1 , by actuating which the direction of the direct current flow in the electric cable 5 can be reversed.

The control panel 1 is further provided with a receiving area 9 in the form of a depression with a smooth bottom surface into which the head part of the treatment head 2 can be inserted. The bottom surface of the recess 9 is formed by a cooling plate shown in more detail in FIG. 3, by means of which a temperature control of the treatment surface of the treatment head 2 makes it reachable.

At a distance from the receiving area 9 , a protruding support 10 is formed on the control panel 1 , on which the handle rests when the treatment head 2 is placed on the control panel.

The treatment head 2 has a handle 11 made of plastic material, which is essentially cylindrical in shape with a diameter suitable for manual gripping, but can also be provided with gripping grooves or the like. The handle 11 has a longitudinally extended middle section 12 of smaller width with flat lateral contact surfaces, to which a heated during operation of the heating and / or cooling device head part 13 and a cooled head part 14 are attached, which project laterally from the sem.

In Fig. 2 the structure of the treatment head 2 is shown in a detailed, exploded view. 2 as can be seen from Fig. , The elongated middle section 12 of the handle 11 is flat and has two through holes 15 , between which a Pel animal element 16 is arranged centrally. The Peltier element 16 is electrically connected to the electrical cable 5 passing through the handle 11 and lies with its two main surfaces in each case in the plane of the flat surfaces of the central section 12 .

The head part 14 is designed as a cylinder made of solid metal, which has two aligned with the through holes 15 Sackboh stanchions 17 with internal thread. The two end walls of the head part 14 are flat. In the assembled state, the end face of the head part 14 visible in FIG. 2 lies directly against the cold-releasing side of the Peltier element 16 , so that very low heat transfer resistance is guaranteed.

In this embodiment, the head part 14 has no nozzles or through openings for the suction pressure field, so that when the head part 14 is used for skin treatment, the skin is only subjected to a cold treatment.

As can be seen from FIG. 2, the head part 13 consists of two cylindrical parts 18 , 20 which are made of metal. The part 20 has a centrally projecting, integrally formed screw 23 , which can be screwed into a corresponding, not shown, central blind hole on the back of the part 18 . In the fully screwed-in state, the parts 18 and 20 lie flat against one another with their flat contact surface, so that good heat transfer is ensured.

The part 20 also has a through hole 22 which is connected loss-free to the air hose 4 passed through the handle 11 .

The head part 18 has on its rear side an incorporated trough, not shown, which is arranged in a circle and is aligned with the outlet opening of the through bore 22 . The distribution channel is coupled to nozzles or through openings 19 in the head part 18 , so that the suction and pressure surges guided through the air hose 4 and the through bore 22 act through the through holes 19 to the outside and at right angles when the head part 18 or 13 is placed on the skin act on the skin surface and massage it.

The part 20 is further provided with through holes 21 which are aligned with the through holes 15 and the blind holes 17 . To assemble the treatment head 2 , the parts 20 and 14 are placed with the holes aligned on the two sides of the elongated section 12 and then connected by screws 24 , which are introduced into the stepped holes 21 with a countersunk head. At closing the front head part 18 is screwed on, where the treatment head 2 is completed. For cleaning purposes, the front head part 18 can be unscrewed and cleaned separately with the nozzles 19 without a complete disassembly of the treatment head 2 being required. The screws 24 . are made of plastic, so that between the parts 14 and 20 no significant heat transfer takes place. In the same way, the elongated section 12 made of plastic acts as a heat barrier, so that the parts 14 and 20 are thermally decoupled.

If a combination of the suction pressure field with the cold instead of the warm side of the treatment head is desired, this can be achieved without having to convert the treatment head simply by reversing the polarity of the power supply of the Peltier element 16 , so that it is then connected to the front according to FIG. forms the cold surface facing the viewer.

The outlet nozzles 19 of the head part 13 are located in front of the front, which thus forms the treatment area for simultaneous suction-pressure treatment and Temperaturbe treatment. The outward-facing end face of the head part 14 forms the opposite treatment surface for cooling treatment (or heat treatment). The temperature difference between the treatment surfaces of the two head parts 13 and 14 can be 20 ° C. or more. Preferably, the treatment area of the head part 13 is kept at a temperature of approximately 38 ° to 40 ° C, while the treatment area of the head part 14 is significantly lower temperature of less than 10 ° C, preferably 4 ° C-8 ° C, may have.

Due to the two-part design of the head part 13 , it is also possible to replace the front part 18 in a simple manner by a head of a different diameter, which has a corresponding threaded bore for screwing onto the threaded connection piece 23 . As a result, the head diameter can be adapted to the skin surface to be treated in a simple, rapid manner.

Alternatively, it is also possible to feed both head parts 13 , 14 with a separately controllable suction pressure field, for which purpose both head parts 13 , 14 are provided with corresponding nozzles.

A temperature control device for regulating the temperature of the head part 13 is shown schematically in FIG. 3. The temperature control takes place externally with the head part 13 inserted into the receiving area 9 , the handle 11 resting on the base 10 in this state. As already stated, the bottom surface of the receiving area 9 is formed by a cooling plate 25 which is provided with cooling fins on its rear side. The top of the cooling plate 25 and thus the Bodenflä surface of the receiving area 9 is regulated to a desired temperature of preferably 38 to 40 ° C. On the surface or on a side surface of the cooling plate 25 , a temperature sensor 26 is present, which detects the surface temperature of the cooling plate or heat sink 25 . The temperature sensor 26 is connected via a line 27 to a control circuit 28 which controls the operation of a cooling fan 30 via a line 29 . The cooling fan 30 is arranged in such a way that it acts on the cooling plate and in particular on its rear cooling fins in order to cool the cooling plate.

The control circuit 28 controls the speed of the cooling fan 30 in dependence on the temperature detected by the temperature sensor 26 he cooling plate temperature preferably such that the surface temperature of the cooling plate 25 is kept at the desired value. When the head part 13 has reached its full operating temperature, the heat sink must dissipate maximum heat output, which is further generated by the Peltier element which is kept continuously in operation. The cooling fan 30 therefore runs at high speed, while it rotates at very low speed when the Peltier element and thus still cool head part 13 are switched on. Since the running noise generated by the cooling fan 30 increases with increasing speed, the device user receives a corresponding indication of the temperature of the head part 13 via the strength of the cooling fan running noise 30 and can thus estimate whether this has already reached the required operating temperature or not .

Even after the switch 7 has been switched off , that is to say after the Peltier element 16 has been switched off , the cooling fan 30 is kept in operation, so that the heat still stored internally in the treatment head 13 can still be extracted (provided the treatment head 2 is correctly inserted in the receiving area 9 filed). This can avoid excessive heating of the head part 13 due to the heat still stored.

During use of the treatment head 2 is lung Hautbehand to the head portion is cooled by the skin 13, so that even when not in the receiving area befindlichem 9 treatmen lung head 2 a can be avoided ver excessive heating of the head part. 13
