Abstract:
A cushion member (2) is for a patient interface device. The cushion member includes a body portion (4), a patient contacting portion (6), and a pre-stressed element (20) located in at least one of the body portion or the patient contacting portion.
Abstract:
A cushion member for use in a patient interface device for delivering a flow of breathing gas to an airway of a patient includes a plurality of dimples defined in a portion of the cushion member.
Abstract:
A method of determining facial metrics of a person includes: receiving a request that the person requires a mask; navigating an autonomously operable vehicle to the person using at least one imaging device; capturing a number of images of the person using the at least one imaging device; and determining facial metrics of the person from the number of images. The method may be further employed in a method for identifying a mask for the person which further includes determining a mask for the user from the facial metrics; and identifying the mask to the person.
Abstract:
A method of improving delivery of a pressure support therapy provided by a pressure support device to a patient via a patient interface device includes begins by receiving current data regarding details of one or more of the patient and the delivery of the pressure support therapy. The current data is then compared to stored data. If a change is determined between the current data and the stored data which is indicative of a poor mask fitment, an indication is provided of a need for a new patient interface device fitting for the patient.
Abstract:
A method of obtaining a 3D scan of a patient's face includes receiving (100) a request for a 3D scanner (4) from the patient (8), sending (101) the 3D scanner to the patient, receiving (102) the 3D scan of the patient's face obtained from the 3D scanner from the patient, receiving (103) the 3D scanner from the patient, and using (104) the 3D scan of the patient's face to make, select, or customize a patient interface device (14) for the patient.
Abstract:
A pressure support device for providing pressure support therapy to a patient includes an airflow generator structured to generate pressure to provide pressure compensation to the patient via a patient circuit, one or more sensors structured to gather data related to effectiveness of the pressure compensation, and a processing unit structured to analyze outputs of the sensors while pressure support therapy is provided to the patient to determine if the pressure compensation provided to the patient is improper and to initiate action to confirm whether components of the patient circuit have been changed in response to determining that the pressure compensation provided to the patient is improper.
Abstract:
A cushion (110, 210, 310, 410) for use in a pressure support system (100) for delivering a flow of breathing gas to an airway of a patient, the cushion comprising: a body (112, 212, 312, 412) comprising a first end (118, 418) and a second end (120, 320, 420) disposed opposite the first end, the body defining a space therein; and a sealing portion (114, 214, 314, 414) defining a single opening (117) into the space, the single opening being adapted to surround both a first nostril and a second nostril of a patient, the sealing portion being disposed between the first end and the second end, the sealing portion comprising an edge portion (116, 216, 316) defining the opening, the edge portion having a first concave portion (125), a second concave portion (127), and a convex portion (128) extending between the first concave portion and the second concave portion, wherein the first concave portion is adapted to seal against an interior surface of the first nostril, and wherein the second concave portion is adapted to seal against an interior surface of the second nostril.
Abstract:
A component - such as a respitratory mask - for use in a user circuit for delivering a flow of a treatment gas to the airway of a patient includes a housing. The housing includes an exterior portion having a number of exterior surfaces positioned to be exposed to a surrounding environment. The housing further includes an interior portion having a number of interior surfaces (30) defining a passageway through the housing. The exterior portion has a first heat capacity and the interior portion has a second heat capacity which is less than the first heat capacity.
Abstract:
An improved connection apparatus is structured to extend between a mask and a headgear. The headgear has a first strap and a second strap structured to overlie the patient's head. The connection apparatus can be generally stated as including a clip apparatus and a face plate. The clip apparatus can be generally stated as including a clip having a first mount that is structured to be connected with the first strap and a second mount that is structured to be connected with the second strap. The face plate is structured to overlie at least a portion of the mask. The face plate can be generally stated as including an attachment apparatus having a connection upon which the clip is structured to be disposed. At least a portion of the clip is removable from at least a portion of the connection.
Abstract:
A device or assisting in performing a 3D scan of a subject includes a camera structured to capture an image of the subject, an indication device structured to provide an indication, and a processing unit structured to determine a difference between a location of the camera and a desired location of the camera based on the captured image and to control the indication device to provide the indication based on the difference between the location of the camera and the desired location of the camera.
