摘要: A microinjection apparatus is designed to introduce the transfecting material into the transductant by inserting a minute injection needle (11) into the transductant and includes a container position adjuster (1), an imaging device (2), a position determiner (3) and a plurality of transporters (4). The container position adjuster adjusts the position of a container (12) accommodating therein the transductant. The imaging device captures through a lens (2a), an image of an inside of the container, which has been adjusted in position by the container position adjuster. The position determiner determines the position of the transductant from the image obtained by the imaging device. The plurality of the transporters are operable to transport the plural injection needles, individually for each of those injection needles, in dependence on the position information obtained by the position determiner.

摘要: This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented.

摘要: A centrifugal blood pump apparatus includes an impeller provided in a blood chamber, first and second permanent magnets provided in one surface and the other surface of the impeller respectively, a third permanent magnet provided in an inner wall of the blood chamber, and a magnetic element and a coil for driving the impeller to rotate with a diaphragm being interposed. First and second grooves for hydrodynamic bearing different in shape and depth from each other are formed in the inner wall of the blood chamber facing the impeller, and third and fourth grooves for hydrodynamic bearing different in shape and depth from each other are formed in the diaphragm facing the impeller. The second and fourth grooves for hydrodynamic bearing generate high hydrodynamic pressure when the impeller is activated to rotate, while the first and third grooves for hydrodynamic bearing generate high hydrodynamic pressure when the impeller steadily rotates.

摘要: A centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a plurality of permanent magnets provided in the impeller, and a plurality of sets of magnetic materials and coils provided in a motor chamber for driving the impeller to rotate with a diaphragm interposed therebetween. The plurality of permanent magnets are aligned with a gap therebetween in a rotation direction of the impeller. Accordingly, if the weight of the permanent magnets is maintained at a constant value, a magnetic field can be strengthened even with a wide motor gap due to the diaphragm, as compared to an example where there is no gap between the permanent magnets.
