<p>FIELD: medicine. ^ SUBSTANCE: invention relates to medical equipment. Surgical cassette has located in it aspiration chamber. Aspiration chamber contains sensitive and accumulative parts. Sensitive part for measurement of flowing medium level is located closer to the bottom of aspiration chamber, is functionally connected with hydraulic line of cassette for obtaining surgical aspirated flowing medium and has first area of transverse section. Accumulative part is located closer to the top of aspiration chamber and is hydraulically connected with sensitive part, and has the second area of transverse section, which is larger than the first area of transverse section. Accumulative part functionally provided respective storage of surgical aspirated flowing medium during replacement of collection bag. Sensitive part is located inside aspiration chamber in such a way that surgical aspirated flowing medium first gets into aspiration chamber through sensitive part from hydraulic line and in fact fills sensitive part, before it gets into accumulative part. ^ EFFECT: application of claimed invention will make it possible to extend arsenal of aspiration and jet-stream technology in eye surgical systems. ^ 2 cl, 3 dwg</p> |
