The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. In one embodiment, the invention includes a spring and swing arm that, when the tubing becomes disconnected from the nipple, align the nipple with a swing arm so that the gas flows through the nipple and the swing arm to actuate the alert.

A patient interface includes a first body that rests on a first portion of a patient's face, a second body that rests on a second portion of the patient's face, and a bridge linking the first and second bodies. The patient interface includes an attachment structure that couples with a complementary fixation structure positioned on the patient's face to secure the patient interface to the patient's face. The complementary fixation structure can be configured to assist in retaining a feeding tube in position relative to the patient's face or to the patient interface.

A filter for an apparatus for delivering a flow of gas, the filter comprising: a filter body, wherein the filter body has a main compartment and a sub-compartment at least partly within the main compartment, wherein the main compartment is in fluid communication with a main compartment gases inlet and the sub-compartment is in fluid communication with a sub-compartment gases inlet; and a filter medium associated with both the main compartment and the sub-compartment, and that is arranged to filter gases in, or exiting, the main compartment and the sub-compartment.

The invention relates to a patient treatment gas supply system having a nasal cannula having a cannula connection and a treatment gas outlet opening; a treatment gas supply line having a line connection which is designed to form a detachable treatment-gas-carrying connection in a connection region with the cannula connection, wherein the cannula connection and the line connection overlap along a flow path formed via the connection region; and a blocking assembly which can be moved between a blocking position and a release position, wherein a force necessary for releasing the connection between the cannula connection and the line connection is greater when the blocking assembly is in the blocking position than when the blocking assembly is in the release position.

Embodiments presented provide for a medical apparatus that allows for administration of a fluid, such as oxygen, to a patient, and to allow a medical professional to quickly and precisely administer such oxygen and/or a gaseous sedative with little waste.

An air delivery conduit includes first and second conduit portions that cooperate to form the conduit, each conduit portion including an inner layer of a film laminate that forms an interior surface of the conduit and an outer layer of a textile that forms an exterior surface of the conduit.

Provided herein are devices, systems, and methods for introducing a nebulized medication into breathing gas for respiratory therapy. An apparatus includes a reservoir to contain a volume of medication, a vibrating mesh disposed at a reservoir outlet of the reservoir to receive a flow of the medication from the reservoir and output a flow of nebulized medication, a mixing chamber having a gas inlet to receive a flow of breathing gas from a gas source, and a nebulizer inlet to receive the flow of nebulized medication from the vibrating mesh, where the vibrating mesh is disposed between the nebulizer inlet and the reservoir outlet. The apparatus can include a pressure tap tube or other implement in fluid communication with the mixing chamber and the reservoir to selectively equalize pressure between the mixing chamber and a headspace in the reservoir above the volume of medication.

An oxygen supply apparatus is configured to directly supply oxygen-containing gas to an user for inhalation while facilitating blood circulation of a specific portion of the user. The oxygen supply apparatus includes a power supply; an oxygen-containing gas source for providing the oxygen-containing gas; a gas catheter having one end thereof connected to the oxygen-containing gas source; an inhalator connected to the other end of the gas catheter; and a circulation facilitating device at least partially attached to the specific portion of the user. The circulation facilitating device includes a sonic oscillation circuit and a housing. The sonic oscillation circuit is configured to produce oscillation at a frequency ranging from 20 Hz to 10 MHz, and the housing encloses the sonic oscillation circuit in a watertight manner

This disclosure relates to a nasal cannula without nostril prongs. The nasal cannula may be used together with an oxygen delivery system, such as a portable oxygen concentrator, or another type of breathing device such as a continuous positive airway pressure (CPAP) machine. In an example, a nasal cannula includes a tube configured to connect to an oxygen supply, and a fitting configured to connect to the tube. The fitting includes a single discharge port having a first section configured to be situated inferior to a first nostril of a user and a second section configured to be situated inferior to a second nostril of the user. Further, the fitting does not include nostril prongs. Because the fitting does not include nostril prongs, patient comfort is dramatically increased relative to prior designs.

In order to acquire patient respiratory information during oxygen concentrator operation, it is necessary to separate patient respiration components and variable pressure components associated with PSA from the measured data of the patient respiration pressure. Provided is a respiratory information acquisition device which acquires respiratory information of a patient and which is used fora PSA-type oxygen concentrator, including a pressure detection unit for detecting pressure in conduit and/or a flow rate detection unit for detecting a gas flow rate in the conduit, and a calculation unit for extracting oxygen respiratory information from detected pressure data and/or flow rate data, wherein the calculation unit estimates a fluctuation component which does not depend on respiration of the patient based on detected data and information related to an operation state of the oxygen concentrator obtained from the oxygen concentrator, and extracts respiratory information by removing the fluctuation component estimated from the detected pressure data and/or the flow rate data.
