В Швейцарии напечатали способное биться сердце

Сердце напечатано исследовательской группы из Высшей технической школы Цюриха в Швейцарии — именно там специалисты с помощью технологий 3D-печати и напечатали искусственное сердце из силикона.

В Швейцарии напечатали способное биться сердце

Другие учёные уже давно начали печатать органы на 3D-принтерах, некоторые даже предпринимали попытки напечатать кровеносную систему, но сердце сделать гораздо сложнее. Пока напечатать точную копию человеческого сердца ни у кого не получилось, более того, учёные пока не знают, как к этому подступиться, но стараются, работают и пробуют новое.

Исследователи из Цюриха отмечают, что их сердце приходит в негодность всего после 3000 тысяч сокращений, а это около получаса работы. Тем не менее, выглядит оно довольно реалистично, да и функционирует похожим на настоящее сердце образом, вполне справляясь с перекачкой жидкости, сходной по плотности с кровью.

Весит сердце 400 граммов и состоит из левого и правого желудочка с дополнительной камерой, которая с помощью сжатого воздуха надувается и сдувается, перекачивая при этом жидкость.

Учёные считают, что останавливаться на достигнутом не стоит, поэтому они продолжат изучать возможности трёхмерной печати и использовать эту и другие технологии для печати органов сердечно-сосудистой системы. Даже если всё идёт не совсем гладко сейчас, то в будущем ситуация наверняка может измениться.

— Мы хотим создать искусственное сердце, которое было бы максимально похожим на настоящее, чтобы его даже можно было пересадить пациенту, — заявляет один из исследователей группы ETH Zurich.

Современные искусственные сердца обычно используются в качестве временного варианта, который позволяет пациенту дождаться пересадки донорского сердца, но доноров часто не хватает, поэтому для многих людей полноценное искусственное сердце могло бы стать отличным вариантом.

I look forward to hearing from you! Great blog by the way!

    I know this if off topic but I’m looking into starting my own blog and was wondering what all is needed to get set up? I’m assuming having a blog like yours would cost a pretty penny?
