  • Patent number: 11871936
    Abstract: Embodiments of the present invention are directed to devices, systems and methods adapted for implementing intermittent displacement of blood to mitigate peripheral nerve neuropathy such as that induced by chemotherapeutic agents (i.e., chemotherapy-induced neuropathy (CIN)) that are administered to a patient. Such devices, systems and methods advantageously provide for precise, uniform and controlled blood flow occluding (and optionally blood displacing) compression along irregular surfaces of an appendage of a patient. Such precise, uniform and controlled blood occluding compression is imparted upon the epidermal and dermis skin layers within the aforementioned areas of a patient's extremities to decrease the time that free nerve endings located in the epidermal and encapsulated nerve endings located in the dermis skin layers are exposed to nerve damaging chemotherapy chemicals, thereby substantially decreasing CIN caused by prolonged exposure to such chemicals.

  • Patent number: 11826502
    Abstract: An oxygenator with a housing wall, which delimits a housing space with a blood inlet and a blood outlet, a gas inlet and a gas outlet, has a heating element which is arranged in the oxygenator between blood inlet and blood outlet in order to control the temperature of blood flowing through the housing space. For this purpose, the oxygenator has a radiation source and a receiver. The radiation source can be an infrared emitter and the receiver a matte-black surface, or the radiation source is an induction coil and the receiver has a material capable of induction. In a method for regulating the heat output on a heating element of an oxygenator, the through-flow of the blood through the oxygenator and the power of a pump acting on the through-flow are measured, and the heating power is adjusted in accordance therewith.
