Design, Manufacturing and Tests of an Implantable Centrifugal Blood Pump
An implantable centrifugal blood pump was developed for longterm ventricular assistance in cardiac patients. In vitro tests were performed, as wear evaluation, performance tests and hemolysis tests in human blood. Numerical computational simulations were performed during design process in order to predict its best geometry. Wear evaluations helped to select the best materials for double pivot b...
متن کاملMagnetic drive system for a new centrifugal rotary blood pump.
The purpose of this investigation was to design a novel magnetic drive and bearing system for a new centrifugal rotary blood pump (CRBP). The drive system consists of two components: (i) permanent magnets within the impeller of the CRBP; and (ii) the driving electromagnets. Orientation of the magnets varies from axial through to 60 degrees included out-lean (conical configuration). Permanent ma...
متن کاملCentrifugal pump failures.
Centrifugal pumps will not pass gross quantities of gaseous emboli due to the nonocclusive nature of the pump. However, retrograde flow can occur under circumstances that include: product malfunctions, low flows, and human errors. Negative pressure created by falling arterial perfusate can draw air into the cannula. Food and Drug Administration (FDA) records about centrifugal pump malfunctions ...
متن کاملGas pump with a magnetically coupled piston
In recent gas-phase nonlinear optics experiments it has been necessaq to prepare gas mixtures with very homogenous composition and temperature inside the measurement cell.’ The gas cell contains a relatively massive electrode structure,’ which is in poor thermal contact with the cell walls, and which leaves no room for an effective stirring device. To effectively mix the gas in the cell we have...
متن کاملThe Impact of Roller Pump vs. Centrifugal Pump on Homologous Blood Transfusion in Pediatric Cardiac Surgery.
Centrifugal pumps are considered to be less destructive to blood elements (1) when compared to roller pumps. However, their large prime volumes render them unsuitable as arterial pumps in heart lung machine (HLM) circuitry for children. In November of 2014, the circuit at Arnold Palmer Hospital, a Biomedicus BP-50 with kinetic assist venous drainage (KAVD) and 1/4″ tubing was converted to a rol...
