Method and device for chemical dispersion of a gel in an organic structure
2001 (English)Patent (Other (popular science, discussion, etc.))
Method and arrangement for chemical dispersion of a gel. In a chamber (8), which is held filled with an aqueous solution, free radicals contaning oxygen are produced. The chamber has an opeing (9) which is brought forward towards the gel (10). The aqueous solution is supplied under pressure through a throttled down nozzle (6). Whirls arise which carry newly created free radicals in contact with the gel which is hereby dispersed to a colloid and exits from the chamber throught a narrow clearance (11) along the edge of the opening of the chamber. The nozzle is aimed in such a way that the flow form there cannot hit the gel directly and fragmentate it mechanically. The free radicals may be produced in the chamber in alot of ways. The most simple measure for this is to raise the pressure before the nozzle (6) so much that a strong turbulence with accompanying cavitation arises. For dispersion of a blood-clot the chamber is built into a spool formed body equipped with an organ for guiding it through bent blood vessels.
