ABSTRACT:
A device for removing material from biological organisms by directing an abrasive fluid stream onto a surface of a biological organism. The device operates on a standard household pressure source and includes a converging-diverging nozzle that produces a super-sonic abrasive-laden air stream having a temperature that is harmless to the biological organism. The device operates at such a temperature without the use of external elements, such as additional heaters or coolers. The internal contour of the nozzle bore is variable and determines conditions, such as, for example, velocity, temperature and shape of the particle-laden air stream.
