  • Patent number: 11413418
    Abstract: A drying expiratory limb of a breathing circuit is provided that is configured to increase or optimize drying of a gas to reduce or prevent condensation. The drying expiratory limb can include a wall that is at least partly made of a breathable material configured to allow transmission of water vapor but substantially prevent transmission of liquid water. The wall includes first and second openings in the wall, the openings respectively configured to receive a gas at a first temperature and a first relative humidity and to allow the gas to exit having a second temperature and a second relative humidity. The drying expiratory limb can be configured to tailor the temperature drop of the gas along the wall to maintain a relative humidity within a targeted range and/or to maintain the gas temperature above its dew point temperature.

  • Publication number: 20220245369
    Abstract: Particular embodiments described herein include an apparatus for providing RFID-based locations for items located in an indoor environment including an RFID scanner to transmit interrogating RFID signals and to receive RFID identifiers for RFID tags, the RFID tags being affixed to the items in the indoor environment. The apparatus can additionally include an indoor location tracking device to determine a current location of the apparatus within the indoor environment, wherein the apparatus is mobile and configured to be moved throughout the indoor environment. The apparatus can further include an RFID-location processor to receive RFID data from the RFID scanner and location data from the indoor location tracking device, correlate portions of the RFID data with portions of the location data, and generate RFID-based location data for the items located in the indoor environment based, at least in part, on the correlated portions of the RFID data and the location data.

  • Publication number: 20220040432
    Abstract: 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.

  • Publication number: 20210379313
    Abstract: This invention relates to a patient interface, such as a nasal cannula, comprising a body to be positioned upon a user (preferably such as a user's face), the body including at least one (and preferably a pair of) nasal prong(s), the or each nasal prong including a lumen capable of being fluidly connected thereto for fluid communication with a supply of breathable gas, the or each nasal prong to be in a configuration either inserted into, or to direct a flow of gas toward, a nare or the nares of the user's nose, wherein the body includes at least one element responsive to force(s) or movement(s), or both, experienced by at least a first region of the patient interface.

  • Publication number: 20210379314
    Abstract: A patient interface, such as a nasal cannula is described. The patient interface has a body portion to be located, in-use upon a face of a user. The body portion has at least one side arm that extends laterally from a central bridge portion to be located about a user's septum region, where each side arm is connected to a resilient, or relatively more rigid, bridge portion element. The interface has at least one, and preferably a pair of, nasal prong(s). The body portion has at least one fluid passageway connected to the nasal prong(s) for supply of a gas to the nare(s) of the user's nose. A cross section of the passageway varies along the length of the body portion to regions of varying flexibility along the body portion. The bridge portion element defines a substantially predetermined spatial relationship for outlet(s) of a gas delivery system supplying gas via each side arm to the outlet(s) from which, for example, the nasal prong(s) may be provided in fluid connection.
