A system and method is disclosed for performing diagnostics on patient devices (720). The patient devices (720) may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server (710) may maintain a database of diagnostic data (718) indicating faults in one or more of a plurality of patient devices (720). The server (710) may transmit this diagnostic data (718) to one or more computing devices (760), including identification of faults that have occurred.

This disclosure describes systems and methods for humidifying ventilator delivered breathing gases. These systems and methods utilize a hollow cone atomizer (e.g., a pressure swirl atomizer) and/or a heating element associated with a heating circuit and/or a heating tube. In some aspect, the systems and methods utilize received flow, temperature, and/or humidity information to determine an amount of water to add to breathing gases to reach a desired humidity of the breathing gases delivered to the patient. In further aspects, the humidification system can serve as a nebulization system for delivering nebulized medicine.

In one embodiment, a filter assembly for use in an insufflation system is described. The filter assembly comprises: a filter medium operative to filter medical gases; a housing comprising an inlet, an outlet and the filter medium, the housing defining a gases flow path through the filter medium between the inlet and the outlet; and at least one heating element being positioned in the housing and being configured to heat the filter medium; and wherein, the at least one heating element is spaced apart from the filter medium and from an inner surface of the housing.

Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

A monitoring connector for a patient ventilation system serves for connecting to a heatable breathing air tube portion for conducting ventilation air from a breathing air source to a patient. The connector further serves for connecting the breathing air tube portion to a patient air interface. The connector has a control/regulation unit and at least one light source that is in signal communication therewith, for visualizing a duration of use of at least one component of the patient ventilation system. The result is a monitoring connector in which reliable operation of the ventilation system without undesirable germ load is ensured with as little undesirable interference as possible.

A breathing gases supply apparatus 1 can comprise a blower 103/105 and breathing circuit for delivering breathing gases to a patient. The apparatus also can comprise a first controller 109, the controller 109 configured to receive input from at least one sensor 110-112 indicative of patient breathing, and a transmitter 201 configured to communicate with the controller 109 and transmit control signals to an electronic apparatus 203. The controller 109 can be configured to determine sleep in a patient based on the occurrence of a breathing pattern indicative of sleep, detected from the input received from the sensor 110-112 and upon determining sleep, operate the transmitter 201 to send a control signal to control an electronic apparatus 203.

Medical tubes and methods of manufacturing medical tubes are disclosed, such as in positive airway pressure (PAP), respirator, anaesthesia, ventilator, and insufflation systems. The tube may be a composite structure made of two or more distinct components spirally wound to form an elongate tube. One of the components may be a spirally wound elongate hollow body, and the other component an elongate structural component spirally wound between turns of the spirally wound hollow body. Alternatively, the tube need not be made from distinct components. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or have other medical uses.

A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.

An air quality monitoring device and an associated method of manufacturing. An example air quality monitoring device may include a housing having a chamber and an inlet port. The inlet port may be structured to receive an air flow from outside the housing and provide the air flow to the chamber. The air quality monitoring device may include a plurality of sensors disposed within the chamber and configured to measure air quality data associated with the air flow. The air quality monitoring device may include an adapter configured to be connected to the inlet port and a continuous positive airway pressure machine. The inlet port may be configured to receive the air flow from the continuous positive airway pressure machine via the adapter. The air quality monitoring device may include a controller connected with the plurality of sensors and configured to transmit the air quality data to a computing device.

The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermistor), of gases flowing through a heated tube, supplying gases to a patient, which utilises the heating wire within the tube.
