Разработка устройства канюли для удаления газовой фракции в системах дренажа крови

Разработка малотравматичных дренажных систем, работа которых направлена на максимально возможное разделение крови и воздуха, является актуальным направлением в современной медицине. Цель данной работы состояла в создании недорогой, удобной в пользовании и малотравматичной системы динамической аспирации крови. Система позволяет эффективно разделить кровь и воздух при заборе крови из раны в условиях вакуума, требуемого для аспирации крови. Принцип действия разработки заключается в разделении жидкой и газовой фракций смеси «кровь–воздух» за счет модификации канюли забора крови. Эффект достигается по технологии применения принципов центробежных сил вращающегося потока «кровь–воздух» в сочетании с подъемными архимедовыми силами.
