ABSTRACT: This work presents the design of a hydrodynamic performance bench (HPB) for evaluating developed prototypes of Ventricular Assist Devices (VADs) used in the treatment of patients with Congestive Heart Failure (CHF), whether as a bridge to recovery, for transplantation or as destination therapy. The HPB is essential for evaluating the performance of VADs under development in Brazil, considering variables such as rotation speed [rpm], flow rate [L/min], pressure [mmHg], and power [W]. The project involves selecting an actuator and transducers for the HPB and developing mechanical components, supervisory control, and modules. The HPB's mechanical components were designed in SolidWorks®, following rapid prototyping, and manufactured using additive manufacturing techniques. The HPB's supervisory program was developed in graphic language using the Labview® program and implemented in a development and application platform with a data acquisition system. The supervisory system's manipulated variable is the motor speed [rpm], acting via an Escon 50/4 EC-S power controller on the BLDC EC45 N339281 motor. In contrast, the controlled variable is the "VAD flow" [L/min] an HT-110 flow transducer provides. A module using particle image velocimetry (PIV) was developed for flow analysis, and all process data are stored in spreadsheets for later consultation. The HPB can assist satisfactorily in analyzing developed VAD prototypes, demonstrating the technical success of the project.
