摘要:
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to neurosurgery, and can be used in surgical treatment of patients with hydrocephaly. Gravitational flow regulator of liquor is a vessel with an inlet opening in which a unidirectional valve of fixed opening pressure is installed to control flow through an inlet, and free outlet and movable plug located inside vessel, which is heavier than medium inside vessel, in movable plug there is a through channel with installed in it valve for flow control through channel, opening pressure of which is greater than opening pressure of unidirectional valve. Regulator is made with possibility to pass liquid flow in one direction. Vessel has a shape providing location of movable plug on inner wall of vessel with horizontal position of regulator, without preventing flow of liquor through inlet valve and outlet, and locking the outlet of the movable plug by abutting its outer surface to the inner surface of the lower portion of the vessel with the vertical position of the regulator, directing flow of liquid or gas through internal channel of plug to outlet hole at pressure inside the vessel, which is greater than pressure of opening of internal valve of plug channel and pressure outside of outlet hole.EFFECT: technical result is to eliminate the need to limit the pressure of opening the outlet valve.1 cl, 2 dwgИзобретение относится к медицине, а именно к нейрохирургии, и может быть использовано при оперативном лечении больных с гидроцефалией. Гравитационный регулятор потока ликвора представляет собой сосуд с входным отверстием, в котором установлен однонаправленный клапан фиксированного давления открытия для регулирования потока через входное отверстие, и свободным выходным отверстием и подвижной пробкой, размещенной внутри сосуда, которая тяжелее среды внутри сосуда, в подвижной пробке имеется сквозной канал с установленным в нем клапаном для регулирования потока через канал, давление открытия которого больше, чем да
