Title: Method for treating the cases of painful closed-angle glaucoma
Inventor: KOZLOV V I
IPC: A61F9/007
Filed: 1996-01-24
Granted: 1999-12-10
Abstract: FIELD: medicine. SUBSTANCE: method involves forming round trepanation holes in sclera 2-7 mm far from the limb. Superficial U-shaped flap is cut in the inferior part of the eyeball before creating the trepanation holes. Flap base is turned to the limb passing through a peripheral area of cornea. The trepanation holes are created on both sides of the U-shaped flap, three on each side, like disk on leg being 1/5 times sclera thickness large. Two rectangular trepanation holes are produced near equatorial edge of the U-shaped flap edge. In creating one of them, sclera is retained on the internal side of the rectangle and implanted between the holes. Middle layers of sclera are notched near the limb and they are removed together with peripheral layers of the cornea to Descemet's membrane without opening the anterior chamber. Iris region having no blood vessels is selected and its coagulation is carried out through Descemet's membrane, in making cross-shaped cut in the Descemet's membrane and trabecule being 1.5 mm in size. Iridectomy is carried out with protruding iris apex being removed to create fistula into the posterior chamber. Collagenous tubular drain is sutured with one of its ends to the fistula. The scleral flap is fixed on its original place. EFFECT: enhanced effectiveness of hypotensive action; improved cosmetic properties. 5 dwg

Filed: 1997-09-22
Granted: 2000-02-10
Abstract: FIELD: different branches of industry. SUBSTANCE: method is used for measuring of liquid and gas flow rate. Method consists in radiation of two ultrasonic waves of different frequency by reversible acoustic transducers along and opposite the flow, simultaneously and in opposition to each other. Method also includes conversion of waves received by acoustic transducers to electric signals and separation of envelope of summary electric signal. Peculiarity of the method consists in that ultrasonic waves are radiated by reversible acoustic transducers at frequencies of mechanical resonance, at relative detuning of frequencies ξ, which is determined by mathematic expression given in the invention description. Envelope of summary electric signal is separated on one of transducers. Voltage amplitude of electric signal envelope across this transducer is maintained constant by changing excitation voltage of other transducer.
