The present invention provides devices and methods for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device includes structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

A mask system for use between a patient and device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

An eyebrow device includes a brow ink pen or pencil connected to a reciprocating or oscillating electric driver, wherein at least one of a stroke length, stroke angle, stroke force, arc length, and cycle rate of the brow ink pen or pencil are adjustable. A computer-implemented method of shaping an eyebrow with ink, includes: creating, by a computing device, a pre-altered eyebrow of a user; creating, by the computing device, a plurality of eyebrow shaping effects; creating, by the computing device, a questionnaire in which the user selects at least one eyebrow shaping effect from the plurality of eyebrow shaping effects; and providing, by the computing device, instructions for an eyebrow device how to shape the pre-altered eyebrow of the user to resemble the eyebrow shaping effect selected by the user.

A mask to administer breathable gas to a user may include a body structure having a connection opening to connect to a line device to deliver the breathable gas; a sealing lip device to seal against the user's face, the sealing lip device joined to the body structure, and the sealing lip device having an upper bridge portion structured to cross the bridge of the user's nose in use, a pair of side portions structured to be positioned along corresponding side surfaces of the user's nose in use, and a lower bridge portion structured to cross the user's upper lip or chin region in use; and a pair of beadlike gel cushions, each positioned in a corresponding one of the side portions.

A method and apparatus can be used in the selection of correctly sized respiratory interfaces. The method includes the use of light beams to project sizing markers onto a patient's face, which enables the size of the patient's facial features to be measured relative to a set of interface sizes. A sizing apparatus can include a light source and beam splitters that will refract and project the light source into a series of beams that can be aligned on a patient's face in order to measure the features of the patient.

Systems and methods for wearable injection guides are described, which include: acquiring one or more digital images of a body region of an individual with at least one image capture device; creating a digitally rendered model of a wearable injection guide from the one or more digital images of the body region of the individual; adding one or more digitally rendered fiducials indicative of at least one treatment parameter to the digitally rendered model of the wearable injection guide; and forming the wearable injection guide from the digitally rendered model of the wearable injection guide, the formed wearable injection guide including one or more fiducials corresponding to the one or more digitally rendered fiducials on the digitally rendered model of the wearable injection guide.

A smart injection system that promotes patient safety includes, among other things, a smart stem that allows for measuring the location of the injection relative to the patient's face and/or the amount of medication injected into the patient. In addition, the smart stem has medication cartridge verification and injector verification features. The smart stem wirelessly transmits the measure data to a processing system.
