  • Patent number: 11918739
    Abstract: 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.

  • Publication number: 20240042148
    Abstract: A head-mounted respiratory assistance apparatus configured to provide a respiratory gases stream to a user. The head-mounted respiratory assistance has a main body securable to the head of a user and a blower unit that is operable to generate a pressurised gases stream from a supply of gases from the surrounding atmosphere. A patient interface is provided on the main body that has a gases inlet which is fluidly connected to the blower unit and which is configured to deliver the pressurised gases to the user's nose and/or mouth.

  • Publication number: 20230390512
    Abstract: Apparatus and methods are disclosed for controlling pressure delivery to a user such as a patient. A flow generator generates an outlet flow at an outlet port for delivery to a patient. At least one sensor measures properties of the flow of gas at the outlet port or being delivered to the patient. A controller is operatively connected to the flow generator and the at least one sensor, and is adapted to operate according to a pressure control mode in which the controller controls the flow generator to output a substantially steady pressure or a flow control mode in which the controller controls the flow generator to output a substantially steady flow. The controller operates in the flow control mode when a patient may be awake and in the pressure control mode when the patient may be asleep.

  • Patent number: 11813400
    Abstract: A patient interface comprises a blower, a cushion for contacting a user's face, and a mask body and/or a frame for supporting the cushion on a user's face. The cushion and/or the mask body or frame define an interior space for receiving a flow of gases from the blower. The blower is mounted to the mask body or frame so that the blower is at least partially within the mask body or frame. The blower substantially separates a high pressure side of the mask body or frame from a low pressure side of the mask body or frame and/or the mask body or frame is substantially without a wall between the blower and the interior space.

  • Publication number: 20230355914
    Abstract: A humidification system has a humidification source and a main gases flow path. The main gases flow path has a low pressure region and a high pressure region. In some embodiments, each of the low pressure region and the high pressure region has an aperture. The pressure difference between the apertures promotes a gases flow between the main gases flow path and the humidification source, and results in humidifying the gases in the main gases flow path.

  • Publication number: 20230338674
    Abstract: A device for delivering gas into a surgical cavity comprising a patient interface having an inlet, fluidly connected with a gas source, and an outlet, the patient interface being configured to deliver a conditioned flow of gas into the surgical cavity. The conditioned flow of gas may have the properties of having a reduced outlet velocity relative to the velocity of the inlet gas, or having a diffuse flow, or being heated, or being substantially laminar or non-turbulent, or a combination thereof. The invention may also comprise an attachment mechanism to attach to or anchor the patient interface.

  • Patent number: 11735298
    Abstract: Data related to the adherence of a patient to a therapy regime can be collected from multiple medical devices, each of which may have an incomplete data set with data entries associated with times. Each incomplete data set represents a portion of a complete data set. The data sets can be integrated to create a complete data set with data entries from each incomplete data set being arranged in a temporal sequence with respect to one another. A report may be generated, the report having the data entries of the complete data set or a function of the data entries of the complete data set.
