摘要： An integrated heart-lung machine, which includes a blood pump having a casing of a cup-like shape interiorly defining a pump chamber at an intermediate portion thereof for pumping in and out blood from a blood inlet to a guide flange formed at opposite ends of the casing; a rotor having a rotary member securely fixed to the fore end thereof within the pump chamber and journalled in the guide flange; an artificial lung of a doughnut-like or cylindrical shape connected contiguously to a blood flow passage in the guide flange and concentrically with the rotor; a stator detachably fitted in an intermediate portion between the rotor and the artificial lung; and a pedestal base located at one side of the artificial lung and provided with a blood outlet in communication with the artificial lung. Accordingly, influent blood to the pump chamber is sent into the artificial lung through the blood passage by the pumping action of the rotor, and is refreshed by contact with air or oxygen in the lung, which is maintained in a heated state by the stator, and returned to the patient's body through the blood outlet. This arrangement permits minimizing of the length of the blood circulating passages to and through the machine and permits shortening and minimizing of the blood passages interconnecting the blood pump, artificial lung and blood filter, while preventing blood contamination and leaks as well as blood cell destruction. Easy installation and handling is also permitted in a sanitary region on a bed or on an operating table.

摘要： A blood pump for circulating blood by a rotor rotating in a space of a casing which is formed substantially in a flat shape and has a suction port and a discharge port, comprises a conical projecting portion provided at the central portion of the rotor, and a blade body formed continuously to a vicinity of the outer periphery of the base portion of the projecting portion, in which upper side recessed passages and lower side passages are alternately and radially formed. Base portions of the upper side recessed passages and the lower side passages are interconnected to each other by communicating passages. With this blood pump, the passages for blood are formed at either of the upper and lower gaps between the rotor and the casing, so that blood is transferred to the outer peripheral portion, thus preventing the solidification of the blood due to the stagnation thereof. This makes it possible to eliminate the problem in causing the thrombus of the peripheral blood vessels by the solidified blood permeating in the body, and in exerting adverse effects on the kidney.
