Abstract

1. Шунт для лечения гидроцефалии при черепно-мозговой имплантации, содержащий помпу из силиконовой резины, образованную между двумя обратными клапанами и мембраной, отличающийся тем, что мембрана выполнена в виде купола с переменным радиусом и переменной толщиной в вершине купола δв и по краям δк δк/δв=1,3±0,1, которой перекрыты с торца два клапана, выполненные в виде цилиндрических втулок на плоском основании, вторая - сегментарно первой, с перегородкой сверху между ними, а втулки выполнены с радиальным отверстием d, поджатым изнутри за счет изгиба лентой, размеры которой определяют сопротивление ΔР и производительность N клапанагде δ - толщина ленты, мм;d - диаметр отверстия клапана, мм;b - ширина ленты, мм;N - расход ликвора, капли/мин, мм/мин;R - внутренний радиус втулки, мм;ΔР - перепад давления, мм вод.ст.2. Шунт по п.1, отличающийся тем, что для неотложной помощи при спинно-мозговой пункции помпа выполнена в виде трубки с торцами, закрытыми клапанами по п.1.1. A shunt for the treatment of hydrocephalus during craniocerebral implantation, containing a silicone rubber pump formed between two check valves and a membrane, characterized in that the membrane is made in the form of a dome with a variable radius and a variable thickness at the top of the dome δв and along the edges δк δк / δв = 1.3 ± 0.1, with which two valves are closed at the end, made in the form of cylindrical bushings on a flat base, the second is segmental to the first, with a partition on top between them, and the bushings are made with a radial hole d, compressed from the inside by and bending tape, the dimensions of which determine the resistance ΔР and productivity N valve where δ - tape thickness, mm; d - valve hole diameter, mm; b - tape width, mm; N - liquor flow rate, drops / min, mm / min; R - internal sleeve radius, mm; ΔР - pressure difference, mm water column; 2. The shunt according to claim 1, characterized in that for emergency care during spinal puncture, the pump is made in the form of a tube with ends closed by valves according to claim 1.
