    摘要: A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

    摘要: The present invention pertains to a pressure support system in which a flow or volume of gas is measured without using a dedicated flow element used in a conventional flow meter. Instead, the present invention provides a tortuous gas flow path in which a pressure differential is created between two points in the tortuous path. This pressure differential created by the gas flow path provides the necessary pressure drop for measuring the gas flow and/or gas volume passing through the pressure support system.

    摘要: A pressure support system has a motor, a switching element that supplies power to motor windings, and a blower coupled to the motor. Rotation of the blower elevates a pressure of fluid in a patient circuit coupled to an outlet of the blower. A rotational speed controller maintains the motor at a set rotational speed corresponding to a selected pressure for the fluid in the patient circuit. The rotational speed of the motor is maintained by a switching signal provided by a rotational speed controller to the switching element to control the actuation of the switching element. A fluid parameter monitoring portion monitors a parameter associated with the flow of fluid in the patient circuit, such as the magnitude, direction, or volume, based on a characteristic, such as duty cycle, of the switching signal, or based on a characteristic of a control signal that is used to generate the switching signal.

    摘要: A pressure support system that includes a pressure generating system employing a pressure generator that provides a primary flow of gas to a patient and a supplemental gas system providing a supplemental flow of gas to the patient. A selectively acutable valve associated with the supplemental gas system controls the supplemental flow of gas to the patient, and a control unit coupled to the pressure generating systems controls the valve based on conditions of the pressure generator in the pressure generating system, thereby controlling the flow of the supplemental gas to the patient based on the detected conditions of the pressure generator.

    摘要: A restraining tube for small animals (preferably animals with tails) is designed to facilitate physiologic measurements of the animal through an integrated or associated sensor mount. The physiologic sensors include those for the measurement of pulse oximetry and other measurements such as breath rate, heart rate, pulse distention and breath distention, temperature to name a few. A tail engaging sensor mount geometry is provided for a particular pulse oximeter into the back plate of the tube. The immobility of the animal is especially important given the fact that pulse oximetry measurements are extremely susceptible to even the smallest motion artifact.

    摘要: A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.
