Patent number: 12285556Abstract: The present disclosure provides systems for controlling infusion of one or more supplements into blood received from a patient. The systems include at least one an extracorporeal circulatory support system including a pump, fluid conduits, and at least one a sensor configured to measure one or more parameters of the blood. The system also may include a fluid flow regulator coupled to the extracorporeal circulatory support system.

Publication number: 20240238117Abstract: A temperature management system controls a temperature of a body of a patient and determines a value indicative of a thermoregulatory activity of the patient. The system includes a heat exchange system configured to exchange heat with a body of a patient and to record operational data while controlling the temperature of the body of the patient. The temperature management system receives temperature data from a sensor, controls the heat exchange system to maintain the temperature of the body of the patient within a target temperature range, receives, in response to the controlling, operational data, determines, based on the temperature data and the operational data, a value indicative of a thermoregulatory activity of the patient, and generates, based on the value, an alert through the user interface indicating the thermoregulatory activity of the patient.Type: ApplicationFiled: March 28, 2024Publication date: July 18, 2024Inventors: George L.

Publication number: 20230405200Abstract: Methods and systems for delivering gas-enriched blood within a vasculature of a patient may include providing a gas-enrichment system, the gas-enrichment system comprising a mixing chamber and a blood pump. The process may include inserting a catheter for drawing blood from the patient into a radial artery of the patient. The process may include drawing blood from the radial artery or from a vessel upstream of the radial artery at a blood flow rate without collapsing the artery or vessel to a degree that would substantially impede drawing blood. The process may include generating a gas-enriched blood by mixing the withdrawn blood with a gas-enriched liquid in a mixing chamber. The process may include delivering the gas-enriched blood to the vasculature of the patient.Type: ApplicationFiled: March 29, 2023Publication date: December 21, 2023Inventors: Ramu Perumal, Jeffrey Lance Creech, Stephen Elwood Myrick, Gary A.
