| 摘要 |
The present invention is a method of dermal abrasion, that includes exposing a source of sterile liquid to a flow of pressurized gas, thereby causing a pumped supply thereof into a fluid delivery head (200); supplying the pressurized gas to the fluid delivery head; combining the gas, and liquid (204) supplied to the delivery head; this fluid delivery head having a fluid outlet (206) with a predetermined internal diameter (210), so as to provide a gas-liquid outflow in the form of a sterile liquid mist jet suspended in a high velocity gas stream; and exposing to the mist jet, at a preselected distance from the fluid outlet, a portion of the skin surface (224) sought to be abraded, thereby separating therefrom at least a portion of the epidermis (225), and removing therefrom the resulting tissue debris. |
