    摘要: A novel cardiac assist blood pump is disclosed. The blood pump comprises a pump chamber, a pressurizing chamber provided adjacent to the pump chamber, a rotor chamber provided adjacent to the pressurizing chamber and an impelled positioned in the pump chamber, said pump being characterized in that the rotation shaft of the impeller means is provided with a first seal member having a skirt portion which is made of an elastomeric material and extends downward to cover the clearance between the rotation shaft and the first rotation shaft hole provided between the pump chamber and the pressurizing chamber and a second seal member similar to the first one which covers the clearance between the rotation shaft and the second rotation shaft hole provided between the pressurizing chamber and the rotor chamber; and tile pressurizing liquid is forced into the pressurizing chamber. The pressurizing liquid penetrates into the pump chamber through the clearance between the rotation shaft and the rotation shaft hole and lifts the skirt portion of the first seal member and the friction between the seal member and tile bottom of the pump chamber is prevented. Also the pressurizing liquid presses the skirt portion of the second seal member and thus prevents leakage of tile pressurizing liquid into the rotor chamber.

    摘要: An extracorporeal blood pump which comprises a pump housing having a pump chamber defined therein, and a rotary vane assembly accommodated within the pump chamber and including a substantially conical rotary pedestal having a base surface and a conical surface, a plurality of vanes each having radially inner and outer ends, and a driven shaft connected at one end with the base surface of the pedestal. The vanes are mounted on the conical surface so as to extend radially outwardly from an axis of rotation of the pedestal with the radially inner ends of the respective vanes being spaced a predetermined equal distance from an apex of the conical surface while substantially depicting a circle coaxial with the axis of rotation of the pedestal. Each neighboring members of the vanes are equally spaced from each other in a direction circumferentially of the pedestal. The base surface has a diameter of 30 to 55 mm enough to substantially cover a surface area of a bottom wall surface which partly defines the pump chamber and confronts the base surface of the pedestal, whereas each of the vanes is in the form of a generally rectangular straight plate extending at an angle of inclination within the range of 20 to 50 degrees relative to an imaginary line tangential to the circle delimited by the radially inner ends of the respective vanes. An extracorporeal blood circulatory device utilizing the blood pump of the type referred to above and comprising a control console accommodating a drive motor for the blood pump is also disclosed.

    摘要: The present invention relates to a bubble elimination method in a medical centrifugal pump wherein a blood outlet 18 is directed upward so that a vertical line X passing through the enter point O of centrifugal pump main body 12 is positioned between two straight lines .alpha.,.beta. which respectively pass through center point O and a point A and center point O and a point B, points A and B lying on the circumference of centrifugal chamber 15 where its periphery connects with blood outlet 18, and a blood inlet 17 is directed upward at an angle which is larger than the angle which is formed between the axis and the inner peripheral surface of centrifuge chamber 15, blood outlet 18 and blood inlet 17 being supported in these states by a drive portion 13 of the centrifugal pump main body 12. After filling the centrifuge chamber with blood and liquid filling, the processes of low speed drive, drive halt and high speed drive are sequentially carried out to rotating body 23. By means of this invention, it is possible to eliminate with surety the lingering of air bubbles inside centrifuge chamber 15 of centrifugal pump main body 12 when initiating circulation of the blood in the circulation path of an artificial heart-lung machine or the like.

    摘要: The purpose is to improve the mixture ratio of a pre-mixer by a simple arrangement to form a more uniform premixed gases so as to materialize low NOx combustion. Two fuel nozzles disposed circumferentially of a pre-mixer are combined with a single air intake window to make a set, which set is used to produce swirls in a pair, thereby expediting mixing. Further, the inlet window is shaped such that its circumferential width is changed axially of the combustor, thereby changing the strength and size of the swirls to achieve the greatest effect. By reducing both the pre-mixer inlet windows and the partition walls in number, the manufacturing cost can be reduced, and by strengthening and optimizing the swirls, a combustor with superior low NOx performance can be provided, while it is possible to reduce the length of the pre-mixer necessary to obtain the same mixture ratio, leading to a cost reduction.
