Изобретение относитс к области медицинской техники, а именно к устройствам, предназначенным дл лечени глаз.The invention relates to the field of medical technology, namely to devices for treating eyes.

Известно устройство дл лечени глаз, содержащее корпус, в основании которого закреплены электрод и пьезодержатель с пьезопреобразователем , подвод щие проводники и ручку 1.A device for treating eyes is known, comprising a housing, at the base of which an electrode and a piezo holder with a piezo transducer, supplying conductors and a handle 1 are fixed.

Однако известное устройство не позвол ет проводить лечение заболеваний центральной зоны глаза без облучени хрусталика.However, the known device does not allow treatment of diseases of the central zone of the eye without irradiating the lens.

Целью изобретени вл етс возможность проведени лечени заболеваний нейтральной зопы глаза без облучени хрусталика.The aim of the invention is the possibility of treating diseases of the neutral eye of the eye without irradiating the lens.

Эта цель достигаетс тем, что устройство снабжено векорасширительной насадкой, выполненной из прозрачного изол ционного материала , на которой по периферии закреплен р д дополнительных пьезодержателей с пьезопреобразовател ми и подвод щими проводнинами , и эластичной мембраной, наружный по сок которой обхватывает корпус, а во внутреннее отверстие вставл етс векорасширительна насадка, причем пьезодержатели на векорасширительной насадке установлены таКИМ образом, что диаграммы излучени пьезопреобразователей имеют общую зону, а их акустические оси пересекаютс с центральной осью корпуса. Векорасщирительна насадка выполнена с центральным отверстием, диаметр которого равеп или оольше диаграммы направлепиостн пьезопреобразовател , установленного в основании корп}са.This goal is achieved by the fact that the device is equipped with a biaxial nozzle made of a transparent insulating material, on which a number of additional piezo holders with piezo-converters and supply conductors are fixed on the periphery, and an elastic membrane, the outer side of which encloses the body, and into the inner hole a expansion nozzle is inserted, with the piezo holders on the expansion nozzle being installed in such a way that the radiation patterns of the piezo transducers have a common area and their acoustic axes intersect with the central axis of the housing. The verassive nozzle is made with a central hole, the diameter of which is equal to or more than the diagram of the directional-piezotransducer installed at the base of the building.

На чертеже изображено предлагаемое устройство дл лечеип глаз.The drawing shows the proposed device for the treatment of the eyes.

Устройство содержит корпус 1, в основании которого закреплены электрод 2 и пьезодержатель 3 с пьезопреобразователе.м 4, подвод щие проводники 5 и 6, ручку 7, векорасширптельную насадку 8, выполненную из прозрачного изол ционного материала, и эластичную мембрану 9. На векорасигирптельной насадке 8 по периферии закреплен р д дополнительных пьезодержателей 10 с пьезопреобразовател ми II и подвод щими проводниками 12. Нарул ный по сок 13 эластичной мембраны 9 обхватывает корпус 1, а во внутреннее ее отверстие вставл ют векорасширительную насадку 8. Пьезодержатели 10 установлены на насадке 8 таким образом, что диаграммы излучени пьезопреобразователей 11 имеют общую зону, а их акустические оси пересекаютс с центральной осью корпуса. Диаметр центрального отверсти 14 векорасщирительной насадки 8 равен или больше дпаграммы направленностп пьезоиреобразовател 4.The device comprises a housing 1, at the base of which an electrode 2 and a piezo holder 3 with a piezo transducer are fixed. 4, supply leads 5 and 6, knob 7, a hypoxia extension nozzle 8 made of transparent insulating material, and an elastic membrane 9. On the vectorasigature attachment 8 a number of additional piezo holders 10 with piezotransducers II and supply conductors 12 are fixed around the periphery. A bow across the juice 13 of the elastic membrane 9 encloses the housing 1, and an expanding nozzle is inserted into its inner opening 8. Pezoderzhateli 10 are mounted on the nozzle 8 in such a manner that the beam pattern of the transducers 11 have a common zone, and their acoustic axes intersect with the central axis of the housing. The diameter of the central hole of the 14th expanding nozzle 8 is equal to or greater than the directivity pattern of the piezo-transducer 4.

Claims

In the treatment of diseases of the central zone of the eye, the device body 1 is filled with a medicinal substance and an elastic membrane 9 is installed, the outer juice 13 of which encloses the housing 1. In the central opening of the membrane, the interstitial nozzle 8 with piezoelectric transducers 11 mounted on the ocular block is lowered. The second electrode for electrophoresis is fixed on the nape of the patient, after which sources of energy are switched on. When the elastic membrane 9 is pressed, the medicinal substance fills the cavity between the nozzle and the eyeblock, thus creating a stable acoustic contact between the piezotransducer 11 and the irradiated eye. In this position, the radiation patterns from piezoelectric transducers 11, mounted on the periphery of the expanding nozzle 8, do not cover the lens location, and their acoustic axes intersect with the central axis of the body at an angle, which ensures the effectiveness of the treatment. The directivity pattern from the piezoelectric transducer 4 through the opening 14 in the expansion attachment 8 irradiates the anterior section of the eye. Claim 1. Device for treating eyes, comprising a housing, at the base of which is fixed an electrode and piezo holder with a sound converter, supplying conductors and a handle, characterized in that, in order to be able to treat diseases of the central zone of the eye without irradiation of the crystalline lens, it is provided with an expanding nozzle made of transparent insulating material, on which along the periphery a number of additional piezo holders with piezo-converters and supply conductors are fixed, and elastic a different membrane, the outer juice of which encloses the body, and the expansion bore is inserted into the inner bore, and the bore holders on the bore head are installed in such a way that the radiation patterns of the piezo transducers have a common zone and their acoustic axes intersect with the central axis of the body.

2. A device according to claim 1, characterized in that the expansion nozzle has a central opening, the diameter of which is equal to or greater than the directional pattern of the piezoelectric transducer mounted at the base of the housing.
