人工心脏泵是众多心衰患者延长生存期最后的希望和最有效的途径ꎮ 第3 …

The durability of a blood pump has been enhanced owing to the development of noncontact
bearings. However, hydrodynamic bearings exhibit a risk of blood trauma owing to their …

We have developed a noncontact‐type centrifugal blood pump with hydrodynamic bearings
and a semi‐open impeller for mechanical circulatory assist. The impeller is levitated by an …

The rapid evolution of rotary blood pump (RBP) technology in the last few decades was
shaped by devices with increased durability, frequently employing magnetic or …

A hydrodynamically levitated centrifugal blood pump with a semi‐open impeller has been
developed for mechanical circulatory assistance. However, a narrow bearing gap has the …

Micropump is the core component of the microfluidic systems. However, most mechanical
micropumps are using the traditional contact bearings that are troubled by wear-out failure …

Good washout is very important in spiral groove bearing (SGB) designs when applied to
blood pumps due to the micrometer scales of lubrication films and groove depths. To …

We developed a simple in vitro antithrombogenic testing method using a mock circulation
system as used in the hemolysis tests to evaluate the antithrombogenicity of centrifugal …

The purpose of this study is to evaluate a spiral groove geometry for a thrust bearing to
improve the hemolysis level in a hydrodynamically levitated centrifugal blood pump. We …

High-efficiency plasma skimming is hopeful to prevent hemolysis inside spiral groove
bearings (SGBs) because it can exclude red blood cells from the ridge gap with a high shear …
