Method and System for Controlled Hyperthermia
20220031921 · 2022-02-03 ·

An improved system and methods for treatment of cancer and other diseases including complications from late-stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented. An adjunct of the present invention is enhanced production of stem cells as a result of employing the HEATT process. A further adjunct is production of transgenic swine with extant viral infections.

An extracorporeal blood circulator includes a control unit and a speed manipulation section. A rotation display section displays a lower limit rotation setting value of a pump motor in accordance with a command of the control unit. The lower limit rotation speed setting value is a minimum rotation speed for preventing backflow of blood inside a circulation circuit A manually adjusted speed setting request from the manipulation section controls the pump speed, except that the controller enforces the lower limit speed setting unless receiving confirmation from a manipulator.

Blood oxygenator

The present disclosure describes a blood oxygenator that includes a checkerboard layout of fluid (e.g., blood) and gas (e.g., oxygen) channels. When viewed as a cross-section through each of the channels of the oxygenator, the checkerboard configuration includes alternating gas and fluid channels in both the x-axis (e.g., in-plane) and in the y-axis (e.g., out-of-plane) directions. The oxygenator described herein reduces manufacturing complexity by using first, second, and third polymer layers that include asymmetrical channel designs. The channel designs include “open” gas channels, which are exposed to the ambient atmosphere. The oxygenator is placed within a pressure vessel to drive gas into each of the open gas channels, which in some implementations, negates the need for a gas manifold.
