Abstract: Изобретение относится к области приема оптического излучения и касается приемника оптического излучения. Приемник включает в себя фоточувствительный элемент, схему обработки сигнала и оптический затвор. Оптический затвор выполнен в виде шторки с двумя рабочими положениями. В состав устройства введен привод шторки, состоящий из источника тока и биморфного элемента в виде двухслойной плоской пружины. Один из слоев биморфного элемента выполнен токопроводящим, противоположные концы которого соединены с выходом источника тока. Второй слой выполнен из прозрачного материала, имеющего более низкий коэффициент температурного расширения. Один конец биморфного элемента неподвижно закреплен на корпусе приемника, а второй скручен по отношению к нему на 90 градусов вокруг продольной оси. Токопроводящий слой нанесен на нижнюю часть биморфного элемента до скрутки, а верхняя часть представляет собой шторку с полупрозрачным покрытием, размещенную так, чтобы при деформации биморфного элемента под действием протекающего тока открывать фоточувствительный элемент. Технический результат заключается в обеспечении работоспособности устройства в условиях активного и пассивного лазерного противодействия при минимальных габаритах и максимальной чувствительности при малом уровне сигналов. 2 з.п. ф-лы, 4 ил., 2 табл.

Проводят отбор исследуемого материала у индивидуума. Забор пробы крови у пациента выполняют в предимплантационный период, кровь центрифугируют для получения популяции мононуклеарных лейкоцитов. Полученную клеточную суспензию вносят в лунки планшета с образцами имплантируемых полимерных материалов в виде цилиндров длиной 3 мм и диаметром 1 мм, в количестве 1 штуки на лунку круглодонного планшета, инкубируют при 5% СО2в течение 72 ч при температуре 37°С. Далее определяют количество мононуклеарных лейкоцитов и концентрацию провоспалительных цитокинов: ИЛ-1β и ИЛ-8. Полученные показатели выражают в виде индекса стимуляции, который рассчитывают по формуле: ИС=УП/УС, предварительно рассчитав удельную продукцию цитокина в присутствии полимерного образца и в присутствии стекла по формулам: УП=Ц/КЛЦ, УС=С/КЛС, где УП - удельная продукция цитокина в присутствии полимерного образца, пг/клетка; Ц - концентрация цитокина в пробе с полимерным образцом, пг/мл; КЛЦ- количество мононуклеарных лейкоцитов в пробе с полимерным образцом, в 1 мл; УС - удельная продукция цитокина в присутствии стекла, пг/клетка; С - концентрация цитокина в пробе со стеклянным образцом, пг/мл; КЛС- количество мононуклеарных лейкоцитов в пробе со стеклом, в 1 мл; ИС - индекс стимуляции. Если индекс стимуляции превышает 1, то констатируют низкую биосовместимость с организмом такого полимерного материала и высокую вероятность развития осложнений при имплантации. Способ обеспечивает возможность индивидуализации оценки биосовместимости полимерного материала, из которого изготовлен имплантат, для конкретного пациента за счет использования популяции мононуклеарных лейкоцитов периферической венозной крови конкретного человека и тестирования их реакции на полимер путем определения индекса стимуляции как отношения удельной продукции основных провоспалительных цитокинов ИЛ-1β и ИЛ-8 в пробе с полимерным образцом к удельной продукции тех же цитокинов в пробе со стеклом. 3 табл., 3 пр.
