DEVICE FOR FINDING LOCATION OF PART INSIDE BODY, MEASURING-WARNING DEVICE AND MEASURING AND REPRESENTING MODULE FOR DEVICE AND METHOD OF GENERATING SIGNAL ON PRESSURE IN POINT OF BODY Russian patent published in 2007 - IPC A61B17/34 A61B5/03 A61M25/06 

FIELD: medical equipment.

SUBSTANCE: device for finding location of anatomical cavity inside body has shallow needle, reservoir filled with fluent medium and communicated with shallow needle, pumping aids for making pressure inside fluent medium, measuring aid for forming signal of measured pressure, which pressure depends on pressure in fluent medium, signal transforming aid for transforming signal of measured pressure, which signal is generated measuring aid, to shape being suitable for subsequent processing, and representing aids for generation of acoustic signal, which signal depends on signal of measured pressure, transformed by means of signal transforming aid, representing aids are made for generation of acoustic signal, which continuously characterizes pressure in fluent medium. Measuring-warning device for finding location of part inside body additionally gas case with space provided inside the case, adapted for mounting reservoir inside it, which reservoir is filled with fluent medium. Reservoir is connected to pumping aids for creating pressure in fluent medium and made for connection to shallow needle. Mentioned aids perform generation of signal in point of body close to sharpened end of shallow needle introduced in body.

EFFECT: improved truth of detection of anatomical cavity; reliable interpretation of measured pressure.
