摘要: An exhalation valve arrangement (22) for a ventilation apparatus for artificial ventilation of patients is flow-capable in an exhalation flow direction (E) and encompasses:
an upstream respiratory gas conduit (54) that extends along a first conduit path (K1) and is connected or connectable to a portion, coming from the patient, of the exhalation line;
a downstream respiratory gas conduit (58) that extends along a second conduit path (K2) and is connected or connectable to a respiratory gas sink (U);
a valve subassembly (63) which comprises a valve body (64) and a valve seat (66) and which is provided between the upstream and the downstream respiratory gas conduit (54, 58) in such a way that, in the context of a predetermined first respiratory gas overpressure in the upstream respiratory gas conduit (54) relative to the downstream respiratory gas conduit (58), it permits an expiratory respiratory gas flow from the upstream respiratory gas conduit (54) into the downstream respiratory gas conduit (58); and in the context of a predetermined second respiratory gas overpressure in the downstream respiratory gas conduit (58) relative to the upstream respiratory gas conduit (54), it blocks a gas flow from the downstream respiratory gas conduit (58) into the upstream respiratory gas conduit (54).
Provision is made according to the present invention that the exhalation valve arrangement (22) comprises a bypass chamber (74) which communicates in terms of flow mechanics with the upstream respiratory gas conduit (54) and which extends, proceeding from the upstream respiratory gas conduit (54), into the region of the downstream respiratory gas conduit (58) and is embodied there for attachment of a gas pressure sensor (80).-

摘要: In accordance with the present invention, there is provided an adaptor or attachment which is suitable for integration into the patient circuit of a ventilation system, such as a non-invasive open ventilation system, is configured for attachment to any standard ventilation mask, and is outfitted with a jet pump which creates pressure and flow by facilitating the entrainment of ambient air. The adaptor comprises a base element and a nozzle element which are operatively coupled to each other. The base element further defines a throat and at least one entrainment port facilitating a path of fluid communication between the throat and ambient air. The nozzle element includes a jet nozzle, and a connector which is adapted to facilitate the fluid coupling of the nozzle element to a bi-lumen tube of the patient circuit. The connector includes both a delivery port and a sensing port. The jet nozzle and the delivery port collectively define a delivery line or lumen which fluidly communicates with the throat of the base element, and is placeable into fluid communication with the delivery lumen of the bi-lumen tube.

摘要: A gas-driven, pressure-regulated ventilator (10, 210) provides support for spontaneous breathing and non-breathing patients. The ventilator provides short pressure cycled and constant flow ventilatory support that allows the patient to receive consistent and reliable ventilatory breaths. The ventilator is designed to allow a clinician to adjust Peak Inspiratory Pressure (PIP) and Positive End Expiratory Pressure (PEEP) values and the duration of inhalation and exhalation flows in a breath cycle to accommodate patient-specific ventilation needs.

摘要: Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators. In some cases, instantaneous impedance or conductance may be used to assess re-connection of a patient circuit, detection of flow starvation, determine breath shape for triggering and cycling and to detect patient or circuit obstructions.

摘要: A compact, on-airway, respiratory gas analyzer for performing pulmonary function tests incorporates an IR spectroscopy light guide having a curved, rather than linear, sample chamber that lies transverse to a direction of respiratory gas flow. Cooperating with the sample chamber is an impact plate that functions to steer respiratory and test gases impinging on the impact plate into the curved sample chamber. A source of IR energy is at one end of the sample chamber and an electro-optical sensor responsive to IR energy is disposed at an opposite end of the chamber. The respiratory gas analyzer also includes gas flow paths and valving for carrying out lung capacity and lung diffusion tests.

摘要: A breathing assistance apparatus capable of operating in alternating inhalation and expiratory phases includes a pressurized respiratory gas source, an inhalation duct to supply gas from the pressurized respiratory gas source to a patient, and an expiratory duct for expiratory gas of the patient. The apparatus further includes a set of flow rate sensors positioned to sense a first flow rate of the expiratory duct and a second flow rate of the inhalation duct, and a controller, including a processor, configured to control the gas source. The inhalation duct includes an inhalation valve, the inhalation valve configured to provide proportional operation and the inhalation valve is selectively controlled by the controller to move to a specific position to allow a desired level of flow through the inhalation valve to the patient.

摘要: Systems and methods are provided for decreasing intracranial pressure and enhancing circulation, as well as for increasing the respiratory rate and encouraging spontaneous respiration. According to such methods, a valve system is coupled with a person's airway. The valve system has an exhalation valve and an patient port that interfaces with the person's airway. The exhalation valve includes a diaphragm having a textured surface. The diaphragm is positioned across an exhalation valve seat and contacts a distal end of the exhalation valve seat, and is configured to prevent or impede respiratory gas flow to the person's lungs until an expiratory pressure equals or exceeds an opening pressure of the exhalation valve, at which time the diaphragm moves away from the distal end to create an open exhaust channel.
