Abstract: A rotary blood pump for transplantation with a large blade is provided to allow generating sufficient flow by low speed rotation of motor and maintaining efficiency of motor in spite of large blade. A rotary blood pump for transplantation comprises: a cylinder shaped case(10) having an inlet and an outlet which are projected from both ends of the cylinder; the first fixation body(20) established in the case, which includes a base part linked to the inner wall of the case through multiple fixation blades and a projection part(22) projected toward the outlet; a cylinder shaped impeller(30) rotatably inserted into the top of projection part in the first fixation body; a blade with longitudinal spiral shape formed on the external surface of the impeller; the second fixation body(40) linked to the inner wall of the case through multiple fixation blades; a magnetic bearing(60) which enables the impeller to maintain a certain location between the first and the second fixation body; a gap sensor(70) established on the wall near to the inlet of the second fixation; and a motor(50) to rotate the impeller centering on the above cylinder.

Abstract: A method for forming a fine electrode using polydimethylsiloxane and the fine electrode formed by the same are provided to improve the adhesive force of the metal fine electrode by optimizing pre-treatment and deposition conditions of a polydimethylsiloxane substrate. A method for forming a fine electrode using polydimethylsiloxane includes the steps of: forming a polydimethylsiloxane substrate by spin-coating a blend on a silicon wafer, wherein the blend is a mixture of a polydimethylsiloxane prepolymer and a hardener in a predetermined mass ratio(110); pre-treating the polydimethylsiloxane substrate(120); patterning the fine electrode after sequentially depositing a titanium layer and a gold layer on the pre-treated polydimethylsiloxane substrate(130,140); forming a photoresist on the patterned fine electrode and spin-coating polydimethylsiloxane on the polydimethylsiloxane substrate without the photoresist(150,160); and packaging the fine electrode by performing gold electroplating on the patterned gold layer after removing the photoresist from the patterned fine electrode(170,180).
