Abstract: A respiratory monitoring system that uses an elastic cord with at least one wire wound around the elastic cord such that, when current passes through, it generates a magnetic field along the length of the elastic cord. The system further includes a recorder that measures changes in inductance and/or frequency in order to derive a respiratory rate of a patient in a coil cord. Embodiments of the system of the present specification have application in Respiratory Inductive Plethysmography (RIP) belts.

Abstract: In part, the disclosure relates to an aspirator having a handle that includes a suction connector extending from a proximal end face, a substantially cylindrical sleeve mount having an outer surface and a shoulder. A tubular member defining a bore and having flared end disposed in a suction head having one or more cantilevered protuberances can extend from the sleeve mount. The substantially cylindrical sleeve mount is in relief with respect to the shoulder and extends distally therefrom. The substantially cylindrical sleeve mount defines an aperture. The suction connector bore, bore of tubular member, inner cavity of handle and suction head bore define a fluid flow path or cavity. The aspirator can include a sleeve that receives the suction head. The sleeve engages and interferes with the sleeve mount. The suction head and sleeve's inner wall have one or more engineered clearances between them to enhance assembly.
