An air conduit for a respiratory therapy device comprises a first end, a second end, and a tube portion, wherein the tube portion comprises a tube wall and an auxiliary structure, such as a rib. The air conduit may deliver a flow of air from a respiratory therapy device or a humidifier to a patient interface. The air conduit may comprise a plurality of auxiliary structures, some of which may consist of a polymeric material, and some of which may comprise a polymeric material and an electrical conductor. An auxiliary structure may be a helical rib extending across a length of the tube portion.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

A respiratory drug delivery device and a method for automating drug delivery are provided. The respiratory drug delivery device may be utilized for delivering a drug to a patient's respiratory tract. The respiratory drug delivery device comprises an inhalation element, an air pipe, a sound sensor, and a drug delivery module, the drug delivery module delivers an aerosolized medicine when the patient inhales based on a sound signal.

A medical system is provided. The medical system includes a medical device and a mobile computing device. The medical device includes at least one physiologic sensor configured to acquire physiological signals from a patient, at least one processor coupled to the at least one physiologic sensor, and at least one optical code encoded with encrypted data. The mobile computing device includes a camera and one or more processors coupled to the camera and configured to acquire one or more images of the at least one optical code, decode the one or more images of the at least one optical code to generate a copy of the encrypted data, decrypt the copy of the encrypted data to generate decrypted data, and process the decrypted data to establish an operable connection between the mobile computing device and the medical device.

The present disclosure relates to a monitoring device for measuring and monitoring breathing parameters and, optionally, oxygenation and/or vital sign parameters of a mechanically ventilated patient, the monitoring device being removably arrangeable at a portion of a ventilator breathing circuit provided between and in fluid connection with a mechanical ventilator and an airway of the patient. The monitoring device comprises a first sensor arrangeable at the fluid connection for measuring parameters related to an airflow in the fluid connection to obtain measurement data; a processor adapted to receive the measurement data from the first sensor and configured to process the measurement data into at least one breathing parameter; and a transmitter adapted to transmit data comprising the at least one breathing parameter to an external device.

Provided are a method for controlling oxygen-containing gas output by an oxygen provider, The method includes: acquiring a first pressure measurement of the oxygen-containing gas at the oxygen provider side; determining a pressure estimation of the oxygen-containing gas at the patient side based on the first pressure measurement, wherein the oxygen-containing gas experiences a pressure drop on the gas pathway to arrive at the patient side; and controlling a target parameter of the oxygen-containing gas output by the oxygen provider based on the pressure estimation. With the method or device for controlling oxygen-containing gas output by an oxygen provider, an automated solution to control the oxygen-containing gas based on a pressure measurement at the oxygen provider side is provided, and the complexity of a medical device for oxygen therapy is reduced.

A bi-level positive airway pressure device includes a housing that has a patient port for connecting to an airway of a patient. There is a device (e.g., a nozzle) for generating a positive airway pressure that is directed through a conduit towards the patient port. An exhalation detector includes a nozzle emitting a jet of a gas directed across the conduit and directed at a receptor channel when exhalation gases flow from the patient port, thereby an increase a gas pressure is present at the receptor channel when the exhalation gases flow from the patient port. The exhalation detector converts the increase in the gas pressure into a movement of an occluding member such that when the exhalation gases flow from the patient port, the occluding member moves to block the means for generating the positive airway pressure.

The present invention relates to a plurality of ventilation devices, to ventilation devices having visualization apparatuses, and to methods for operating the ventilation devices. The intent is to minimize the energy input into the at least one airway of a patient as a result of the ventilation.

A fluid control device includes a case including an internal space that is partitioned by a partition wall into an air blowing chamber and a control chamber. A dividing wall is disposed inside the air blowing chamber to partition an internal space of the air blowing chamber into a first air blowing chamber and a second air blowing chamber. A fan unit is housed in the second air blowing chamber. A differential pressure sensor senses a differential pressure between a pressure inside the first air blowing chamber and a pressure inside the second air blowing chamber. A controller controls a fan based on the sensed differential pressure.

A respiratory therapy system can have a flow generator adapted to provide gases to a patient. A gas passageway can be located in-line with the flow generator. The gas passageway can have a first portion adapted to receive a first gas and a second portion adapted to receive a second gas. The gas passageway can have a static mixer downstream of the first and second portions.
