Цель работы: провести стендовые испытания и определить рабочий диапазон скорости насоса имплан- тированной системы обхода левого желудочка сердца для дальнейшей диагностики и лечения пациентов с малыми антропометрическими показателями.

Материалы и методы

Материалы и методы. Исследование осевого насоса проводилось на разработанном нами гидродинамическом стенде, имитирующем сердечно-сосудистую систему и включающем в себя систему измерения и регистрации давлений и расхода, а также программное обеспечение для обработки технических и биомедицинских параметров.

Результаты

Результаты. Рабочий диапазон скорости вращения ротора насоса «СТРИМ КАРДИО» для достижения скорости потока в 2,5 ± 0,5 л/мин при перепаде давления 80 ± 5 мм рт. ст. будет равным 8000 ± 1000 об/мин, при этом потребляемая мощ- ность будет составлять 6,5 ± 1 Вт.

Objective

Objective: to conduct bench tests and determine the working range of the pump speed for an implanted left ven- tricular bypass system aimed at diagnosing and treating patients with low anthropometric status.

Materials and methods

Materials and methods. The axial pump was investigated using a custom-developed hydrodynamic test bench simulating the cardiovascular system. The bench included systems for pressure and flow measurement and registration, along with software for processing both technical and biomedical parameters.

Results

Results. The operating range of the rotor speed for the STREAM CARDIO pump required to achieve a flow rate of 2.5 ± 0.5 L/min at a pressure drop of 80 ± 5 mm Hg is 8000 ± 1000 rpm, with a power consumption of 6.5 ± 1 W.
