Description

Suction device

The present invention relates to a suction device comprising a receptacle consisting of a bottom wall and a side wall and having an opening opposite the bottom wall and bordered by the side wall, the receptacle defining a cavity, the device suction comprising a pipe opening into the cavity and capable of being connected to a suction system which is capable of sucking a fatty fold into the cavity.

Cryolipolysis consists of applying cold (temperature below 0°C, typically around -10°C) to a part of the human body in order to destroy unwanted fat cells with cold. Cryolipolysis is therefore an aesthetic and non-invasive treatment of the human body.

Cryolipolysis treatments require the formation of a fatty fold which is intended to be sucked into the cavity of an applicator shaped especially for this application. The fatty fold is sucked into the cavity by a suction system connected to this cavity. The fatty fold thus comes into contact with the surface bordering the cavity (side wall of the applicator) to be cooled there. The depth of the applicator, the texture of the skin, the thickness of the skin,… are all factors to take into account to have a cryolipolysis treatment that is effective and painless. The effectiveness of the treatment is determined by the good contact between the skin of the fat fold and the cooling cavity, so that the cooling cavity can cool the fat fold well.

In some cryolipolysis applicators all or most of the side wall of the cavity is cooled, typically by circulation of a cryogenic liquid in a conduit located in this side wall. Figure 5 shows such applicators 200, with various geometries. The side wall 212 of the applicator 200 surrounds and defines a cavity 220 in which a depression is established using a suction system (not shown) which is connected to this cavity. The side wall 212 is cooled over all or most of its surface, which makes such an applicator 200 more efficient.

The disadvantage is that the side wall 212 is then necessarily entirely opaque, and consequently it is not possible to see the rise of the fat fold of the individual in the cavity 220. It is therefore difficult to adjust the intensity correctly. depression or to know the behavior of the fat fold as it is sucked into the cavity.

Description of the invention

The present invention aims to remedy these drawbacks.

The invention aims to propose a suction device comprising a cavity, and which makes it possible to know, quickly and economically, the behavior of the fatty fold while it is sucked into this cavity, so as to allow an appropriate adjustment of the intensity of the cooling and the amplitude of the aspiration for the treatment of the fatty fold.

This object is achieved thanks to the fact that the side wall comprises a transparent portion through which a fatty fold located in said receptacle is visible, the suction device being devoid of a side wall cooling system.

Thanks to these provisions, we see the rise of the fatty fold in the cavity. The fact that the suction device does not have a cooling device on its side wall means that there are no limits on the positioning or the extent of the transparent portion of the side wall. Thus, we can effectively and quickly calibrate the rise of the fatty fold. One can then knowingly choose a cryolipolysis applicator whose entire side wall of the cavity is opaque, and whose size and geometry of the cavity are appropriate for the specific treatment of the fatty fold which was tested in the suction device according to the invention.

Advantageously, the transparent portion extends in height from the opening to the bottom wall.

Thus, we can observe the rise of the fatty fold in the cavity over the entire height of the cavity if necessary.

Advantageously, the transparent portion forms the entire side wall.

Thus, one can observe the behavior of the fatty fold while it is sucked into the cavity, whatever the angle of view under which one observes the suction device 1.

Advantageously, the transparent portion includes a graduation which makes it possible to measure the height of the fatty fold in the receptacle.

Thus, we can quantify the rise of the fatty fold in the receptacle for a given suction power.

Advantageously, the pipe opens into the cavity via the bottom wall.

Thus, the aspiration of the fat fold can be carried out over the entire height of the side wall.

Advantageously, the suction device further comprises a suction system connected to the pipe.

Advantageously, the bottom wall comprises another transparent portion through which a fatty fold located in the receptacle is visible.

Thus, we can better observe the behavior of the fatty fold as it is sucked into the cavity,

The invention also relates to an assembly consisting of a suction device according to the invention and a cryolipolysis applicator comprising a bottom wall and an opaque side wall defining a cavity which is opened by an opening opposite the wall of the bottom, the cryolipolysis applicator further comprising a cooling system capable of cooling the side wall of the cryolipolysis applicator, and a suction system which is capable of sucking a fatty fold into the cavity.

Detailed description of the invention

Figure 1 shows a suction device 1 according to the invention. This suction device 1 comprises a receptacle 10 consisting of a bottom wall 11 and a side wall 12 and having an opening 13 opposite the bottom wall 11 and bordered by the side wall 12. The receptacle 10 thus defines a cavity 20. The suction device 1 comprises a pipe 30 opening into the cavity 20 and capable of being connected to a suction system 40. This suction system 40 is used to suck into the cavity 20 a fatty fold 90 d an individual for future treatment of this fat fold 90 by cryolipolysis. This fatty fold is shown in dotted lines.

The pipe 30 opens into the cavity 20 at the level of the bottom wall 11. Thus, the suction of a fatty fold 90 can take place over the entire height of the side wall 12. The height of the side wall 12 ( or of the cavity 20) is defined as the distance between the opening 13 and the bottom wall 11. Alternatively, the pipe 30 opens into the cavity 20 at the level of the side wall 12.

The side wall 12 has a transparent portion 125 through which a fatty fold 90 which is sucked into the receptacle 10 is visible. For example, the transparent portion 125 extends in height from the opening 13 to the bottom wall 11. For example, the transparent portion 125 forms the whole of the side wall 12, so that it is possible to see the fatty fold 90 in the receptacle 10 regardless of the angle from which the side wall 12 is observed.

The suction device 1 does not have a cooling system for the side wall 12. Thus, as indicated above, the entire side wall 12 can be transparent, as indicated above. One can then freely observe the behavior of the fatty fold 90 as it is sucked into the cavity 20.

The suction device 1 is therefore intended to be used at room temperature on an individual, that is to say that the side wall 12 and the bottom wall 11 of the suction device 1 are at room temperature. By "ambient temperature" is meant a temperature of the order of 20°C.

The absence of a cooling system in the suction device 1 makes it possible to simplify the manufacture, the cost, and the use of the suction device 1. Thus, the suction device 1 can be made of plastic, formed by molding . The molding can be made from a single polymer, or from several polymers, one of which forms the transparent portion 125. Alternatively, the suction device 1 is made of glass.

Advantageously, the transparent portion 125 is provided with a graduation 126 which extends from the opening 13 to the bottom wall 11, as illustrated in FIG. 1. This graduation 126 makes it possible to quantify the rise of the fatty fold 90 ( height of the fatty fold 90 in relation to the opening 13) in the cavity 20.

Figures 2, 3, and 4 show such a suction device 1 with a fatty fold 90 which is sucked into the cavity 20 at different heights, respectively from the lowest to the highest.

In one embodiment, the suction device 1 as described above further comprises the suction system 40 which is connected to the pipe 30.

In one embodiment, as illustrated in FIG. 1, the bottom wall 11 comprises another transparent portion 115 through which a fatty fold 90 located in the receptacle 10 is visible. This other transparent portion 115 can form part or all of the bottom wall 11. In this case, as illustrated in Figure 1, the graduation 126 can extend from the side wall 12 into the bottom wall 11.

The invention also relates to an assembly consisting of the suction device 1 according to the invention and a cryolipolysis applicator 200 (shown in FIG. 5) whose side wall 212 is opaque and cooled, and which is intended to be used together with suction device 1.

This cryolipolysis applicator 200, illustrated in FIG. 5, comprises a bottom wall and an opaque side wall 212 defining a cavity 220 which is open by an opening opposite the bottom wall, and further comprises a cooling system (not shown ) capable of cooling the side wall 212, and a suction system (not shown) which is capable of sucking into the cavity 220 a fatty fold 90. This suction system is connected to the cavity 220 by a pipe which opens into this cavity 220. This suction system is the same as the suction system 40 used with the suction device 1, or is separate from it. The cooling of the side wall 212 is to a temperature below 0°C, typically of the order of -10°C.

Advantageously, the geometry and the size of the cavity 220 of the cryolipolysis applicator 200 are similar or identical to the geometry and the size of the cavity 20 of the suction device 1. Thus, one can directly know the behavior of the fold fat 90 in the cryolipolysis applicator 200 after observing the behavior of the fat fold 90 in the suction device 1. The suction intensity of the fat fold 90 in the suction device 1 is calibrated to treat this fold greasy 90 in the most effective way. Then, the treatment of the fatty fold 90 in the cryolipolysis applicator 200 can be optimized by adjusting the amplitude of the suction in the same way as the amplitude of the suction in the suction device 1. The cooling intensity in the 200 cryolipolysis applicator for optimal treatment of this 90 fat fold.
