Publication number: 20210283357Abstract: The systems, devices, and methods described herein relate to providing breathing gas to a patient using a base unit and an auxiliary unit configured to be removably disposed on or at least partially in the base unit. The base unit has several couplings for improved control and sensing of the auxiliary unit and its components, wherein the couplings are configured to be non-contact with the corresponding components of the auxiliary unit and/or otherwise configured to minimize operational defects or improve efficiency. Non-contact couplings include induction heating, capacitive level sensing, a magnetically coupled rotor pump, RFID tag and reader, and Hall effect sensing. The breathing gas can be provided at high velocities by setting breathing gas flowrates based on dimensions of a nasal cannula used to direct the breathing gas into a patient's nares.Type: ApplicationFiled: June 15, 2020Publication date: September 16, 2021Inventors: Scott A.

Publication number: 20210285435Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfectants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).Type: ApplicationFiled: December 21, 2020Publication date: September 16, 2021Applicant: DEKA Products Limited PartnershipInventors: Brian D.
