AI Technical Summary

Problems solved by technology

Cooling an area to too low a temperature can cause excessive damage
Cooling the area for too long can cause the cold to spread to adjacent tissues, increasing the size of the affected area
Furthermore, while surrounding tissue survives brief exposure to extremely low temperatures, prolonged exposure can lead to tissue necrosis or excessive damage

Embodiment Construction

[0104] Figure 1A and 1B respectively shows a dispensing system 1 according to the invention, wherein the actuatable valve 20 is closed, thereby preventing fluid and gas from inside the container from flowing out of the container 10 through the nozzle 30, and with the valve 20 open, the nozzle 30 is in fluid communication with the interior of container 10 . Although in the illustrated embodiment the nozzle 30 comprises two parts 32, 33 connected to each other, it should be understood that the nozzle could also be formed as a single unit.

[0105] The internal volume of the vessel is about 120 ml for containing the liquid phase 11 and the gaseous phase 12 in direct contact with each other. In the embodiment shown, both the liquid and gas phases are at a pressure of about 4 bar, the liquid phase 11 consisting of liquefied dimethyl ether. Alternatively, liquid phase 11 may consist of a 3:1 (w / w) mixture of liquefied dimethyl ether and liquefied propane.

[0106] The nozzle 30 ...

Abstract

The invention relates to a dispensing system for use in cryogenic skin treatment that is capable of targeted delivery of a cryogen at a high rate, thereby achieving rapid freezing of targeted skin tissue. The dispensing system of the present invention uses a cryogen that contains dimethyl ether and is designed to deliver the cryogen in an accurate and very effective manner.

Description

[0001] field of invention [0002] The present invention relates to dispensing systems for cryogenic skin treatments. The dispensing system of the present invention comprises: [0003] Containers containing cryogens; [0004] an actuatable valve comprising a chamber and a nozzle connected to an outlet of the chamber; [0005] A spacer attached to the container or the valve, the spacer being adapted to define a predetermined distance between the orifice of the nozzle and the skin surface to be treated. [0006] The dispensing system of the present invention may suitably be used to improve the appearance of the skin by treating warts, moles, freckles, skin tags, age spots, lentigo or other skin-related abnormalities. Accordingly, the present invention also relates to a cosmetic method of treating the skin, said method comprising the topical application of the low-temperature dispersion to the skin of a human or animal using a dispensing system as described above.
