摘要： The invention is directed to an artificial heart having a pump, first and second pair of switching valves, and an electronic control unit which is arranged to control the valves to be actuated synchronously. When one of the first pair of valves and one of the second pair of valves are actuated to open, while the rest of them close, a blood from a right atrium is sucked and released by a pump through one of the first pair of valves, and subsequently, supplied into a pulmonary artery through one of the second pair of valves. At this time, a left atrium and an aorta are shut off, since the other ones of the first and second pair of valves are closed. Whereas, when the other ones of the first and second pair of valves are actuated to open while the rest of them close, the blood from the left atrium is sucked and released by the pump through the other of the first pair of valves, and subsequently, supplied into the aorta through the other of the second pair of valves. At this time, the right atrium and the pulmonary artery are shut off. By repeating these, the right and left systems of the heart operate alternately.

摘要： Disclosed is a medical valve apparatus having a valve assembly which comprises a valve seat and a movable valve, and which is arranged in a duct of a medical appliance, wherein a plurality of through holes for the passage of a fluid are formed through the valve seat, the movable valve is composed of a flexible membrane, and the movable membrane is fixed on the valve seat substantially at the central point thereof. The flexible membrane has a corolla-like shape at the time of a forward flow to allow a free flow of the fluid passing in the through holes, and at the time of a back flow, the flexible membrane is wide-spread to adhere to the valve seat and close the through holes whereby the passage of the regurgitation is prevented. Preferably, the peripheral edge of the valve seat is integrated with the inner wall of the duct of the medical appliance without a seam therebetween.
摘要翻译：公开了一种具有阀组件的医疗阀装置，该阀组件包括阀座和可移动阀，并且布置在医疗器具的管道中，其中通过阀座形成多个用于流体通过的通孔可动阀由柔性膜构成，可移动膜基本上固定在阀座的中心点。柔性膜在向前流动时具有花冠状形状，以允许流过通孔的流体自由流动，并且在回流时，柔性膜被广泛地粘附到阀座并关闭通孔，从而防止反流通过。优选地，阀座的周边边缘与医疗器械的管道的内壁成一体，而在它们之间没有接缝。
