NON-INVASIVE DEVICE FOR REJUVENATION OF SKIN TISSUE USING TREATMENT PRESSURE BELOW AMBIENT PRESSURE
First Claim
1. A non-invasive device for rejuvenation of skin tissue, the non-invasive device comprising:
- a suction chamber having a skin contact surface comprising an opening for exposing the skin tissue to a treatment pressure present (Pt) in the suction chamber for applying a suction force to a portion of an outer surface of the skin tissue corresponding to an area of the opening, the treatment pressure being lower than an ambient pressure outside the suction chamber, and the suction chamber being dimensioned so as to allow it to be manually applied to the outer surface of the skin tissue, anda controller for controlling a level of the treatment pressure in the suction chamber and for controlling an application time interval (Δ
t) of the treatment pressure (Pt),wherein the controller is configured for controlling the level of the treatment pressure (Pt) in the suction chamber and for controlling the application time interval (Δ
t) of the treatment pressure (Pt) for damaging an interface between an epidermis layer and a dermis layer of the skin tissue to initiate rejuvenation of the skin tissue,wherein the area of the opening in the suction chamber is less than 10 square millimeters.

Abstract
The invention provides a non-invasive device (100) for skin rejuvenation using a treatment pressure below ambient pressure, and provides a method and a computer program product. The non-invasive device comprises a suction chamber (110) having a skin contact surface (115) comprising an opening (120) for exposing the skin tissue (200) to the suction chamber for applying a suction force to an outer surface (210) of the skin tissue. The opening in the suction chamber is less than 10 square millimeters. The suction chamber is dimensioned so as to allow it to be manually applied to the outer surface of the skin tissue. The non-invasive device further comprises a controller (140) for controlling a level of treatment pressure (Pt) inside the suction chamber (110) and for controlling an application time interval (Δt) of the treatment pressure for damaging an interface (225) between an epidermis layer (220) and a dermis layer (230) of the skin tissue.

15. A skin treatment method for rejuvenating skin tissue, the method comprising the steps of:
-
bringing a suction chamber into contact with an outer surface of skin tissue, the suction chamber having a skin contact surface comprising an opening for exposing the skin tissue to a treatment pressure (Pt) present in the suction chamber for applying a suction force to a portion of the outer surface of the skin tissue corresponding to an area of the opening, the treatment pressure (Pt) being lower than an ambient pressure outside the suction chamber, and the suction chamber being dimensioned so as to allow it to be manually applied to the outer surface of the skin tissue, and applying a level of treatment pressure (Pt) during an application time interval (Δ
t) to the outer surface of the skin tissue, using the suction chamber, wherein said applying the level of treatment pressure (Pt) during the application time interval (Δ
t) to the outer surface of the skin tissue is for damaging an interface between an epidermis layer and a dermis layer of the skin tissue to initiate rejuvenation of the skin tissue, wherein the area of the opening in the suction chamber is less than 10 square millimeters.
