ABSTRACT:
Apparatus and a method for performing extracorporeal treatment of a patient's blood for various conditions. The apparatus includes means by which an extracorporeal blood circuit is defined. Such a blood flow circuit includes first means for cannulating a vein of a patient to define a blood egress point and second means for cannulating an artery of the patient to define a blood ingress point. A discontinuous conduit is provided to interconnect, in part, the first and second cannulating means. The apparatus also includes a module which includes a conduit portion. The module integrates a number of components into a single unit, and the conduit portion thereof is able to be interposed in the discontinuity in the discontinuous conduit to complete the blood flow circuit. The various components which are connected in the conduit portion include a pump, a device such as a heat exchanger to regulate the temperature of blood flowing through the conduit portion, and means for sensing the temperature, pressure, and flow rate of the blood passing through the conduit portion. In some applications, an oxygenator can also be included. A control console is provided to enable pressure and flow rate of the blood passing through the conduit portion to be controlled. Similarly, appropriate controls can be employed to regulate the temperature, and, when an oxygenator is included, a controller would, typically, be provided for the oxygenator also.
