Bench Tests of an Implantable Axial Blood Pump
Biomedical Engineering, 2011Methods and results of tests of biomedical parameters of a new accessory circulation apparatus based on implantable axial blood pump are discussed in this work. Bench tests were directed toward determining energy parameters and pump-induced injury of blood cells. The results of the tests allowed efficiency of the developed system to be evaluated within

Hydromechanical principles of axial pumps
1991Generally, pumps can be classified into two main categories: displacement pumps and rotary pumps. The energy transfer in displacement pumps is characterized by periodic changes of a working space. Typical displacement pump types are piston pumps, gear pumps or roller pumps.

The Performance of an Axial-Flow Pump
Proceedings of the Institution of Mechanical Engineers, 1956Tests were made on an 11-inch diameter axial-flow propeller pump with impeller and guide blades designed for free vortex conditions, using as a basis the modified aerofoil theory. The best overall efficiency obtained was 82 per cent. Apart from head-flow and efficiency characteristics, measurements were made of velocities and yaw angles within the ...

Relationship Between Pump Speed Design and Hemolysis in an Axial Flow Blood Pump
Artificial Organs, 1996AbstractIn an attempt to reduce the hemolysis caused by axial flow blood pumps, we investigated whether the specific speed should be kept within the standard engineering range or whether pump speed should be minimized, thus making the specific speed beyond the standard range.

[The design of axial flow pump].
Sheng wu yi xue gong cheng xue za zhi = Journal of biomedical engineering = Shengwu yixue gongchengxue zazhi, 2002Axial flow pump has been the hot point of the research field of circulatory support. This article has outlined the basic principle of its design and the methodology of its experimental study, and explained that excellent engineer design, avoiding turbulence, cavitation and wake, and reducing the destroy of red blood cells were the goal to get in design

The Design of Axial Flow Pumps
Journal of Fluids Engineering, 1956Abstract A design procedure for axial-flow pump impellers is presented that accounts for induced interference effects in the prediction of performance. Induced interference velocities at an impeller blade have been calculated using a three-dimensional model that includes the effects of the other blades and of the total downstream ...

Each year, thousands of cardiac patients await healthy donor hearts for transplantation. Due to the current shortage of donor hearts (approximately 2300 per year), these patients often require supplemental circulatory support until a transplant becomes available. This supplemental support is often provided by a mechanical heart pump or left ventricular
