Abstract: A computer-controlled medical care system for use in the treatment and diagnosis of patients provides for either automatic or manual control of a wide variety of medical procedures including diagnostic procedures. The system accepts modular vessel structures, each type of structure being adapted for carrying out a specific procedure and matching programs for carrying out the specific procedures. A microcomputer accepts a program which may be designed to fit the needs of a specific patient and which must watch the modular vessel structure. The microcomputer monitors the progress of the process and the physiological status of the patient and provides for the taking of appropriate steps should difficulties be encountered in carrying out the procedure. The system can also be programmed to analyze a fluid taken from an individual, to treat the fluid and return same to the individual and to schedule the infusion of appropriate medications.

Abstract: A fluid-transfer system has two pistons movable within a barrel so that the ends of the piston faces can move together or apart, the barrel having at least two openings therein for transfer of fluid into and out of said barrel. The pistons can be controlled manually, mechanically or by computer to draw fluid from one or more reservoirs into the barrel and transfer the selected fluid in selected quantity into a chamber for storage or for reaction or analysis. The system is particularly useful for transfer of fluid from a selected chamber to another selected chamber, for mixing fluids, and for carrying out multiple tests on blood taken from a patient or from a plurality of patients under the control of a computer, which can accept programs for carrying out specific procedures.

Abstract: An apparatus for extracorporeal treatment of blood can carry through automatically such functions as dialysis and oxygenation compensating, in the process, for changes in the condition of the patient. A fail-safe monitor receives signals from a number of sensors all of which must provide signals within acceptable ranges in order for the apparatus to continue to function. Deviation of a signal outside the corresponding acceptable range for longer than a preset period causes the fail-safe monitor to stop the flow of blood taken from the subject and to activate an alarm. The apparatus may be so constructed that the ducting through which blood and other fluids flow can be caused to act as valves and pumps by suitably applied pressure. Also, such portions of the apparatus can be made in a form which is sufficiently economical so that they can be regarded as disposable. The apparatus may be designed so that it can be programmed for specific patients and for treatment of specific conditions.
