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.

Systems and methods are provided for identifying a therapeutic VR activity or exercise for a subject/patient based on the subject's impairments, dynamically adjusting a VR activity for a patient, and identifying potential impairments based on a patient's performance in a VR activity. Patients may each have various physical, neurological, cognitive, and/or sensory impairments to be treated. Not all therapeutic activities may be appropriate for some patients and their impairments. A VR therapeutic activity platform may increase patient engagement and challenge patients at more appropriate times by better matching activities corresponding to a patient's impairments and dynamically adjusting each VR activity based on performance to offer a challenging and rewarding therapeutic experience.

A minimal weight patient interface device that delivers breathing gas to a user includes a cushion assembling including a support cushion assembly and a sealing member is described herein. In one exemplary embodiment, the support cushion assembly includes a wedge that is made of a high density foam received within a wedge receiving portion of the support cushion assembly. In the exemplary embodiment, the cushion assembly is formed by the sealing member fitting over the support cushion assembly. The sealing member, in one embodiment, is made of silicone, for example, having a low durometer value (e.g., between 5-10 Shore 00). Furthermore, in one embodiment, the patient interface device also includes a faceplate that is placed over the cushion assembly and is made of a thermoform, such as a high density foam laminated between two pieces of fabric, such as polyester.

An awakening inducing device induces a vibration device disposed in a seat at a position where the vibration device opposes at least one of a muscle belly portion or an insertion portion of a hamstring of a user sitting on the seat; and a control device that, by controlling the vibration device, causes the vibration device to given vibration stimulation to at least one of the muscle belly portion or the insertion portion.

The present patent document describes methods for enhancing the aesthetic appearance of a human face by injecting soft tissue filler material in the temporal region. The soft tissue filler material is injected into a subdermal plane; preferably from an injection site about 1 cm anterior to the apex of the tragus. A single injection may be performed on either side of the face.

An intelligent psychological assessment and intervention system based on an independent space, comprising a psychological intervention cabin and a central database which achieves data interaction with the psychological intervention cabin. The psychological intervention cabin comprises a housing, a data acquisition module, a data processing module, and an intervention module; the data acquisition module acquires physiological and psychological data of a subject; the data processing module performs operations on the acquired data, establishes a multi-dimensional state point of the subject according to a mathematical model of the data processing module, matches it with data in the central database, finds a suitable intervention procedure for the subject, and guides the intervention module to carry out intervention; in the intervention process, the data acquisition module continuously acquires the physiological and psychological data of the subject, and the data processing module forms a new multi-dimensional state point according to new data and re-matches it to adjust the intervention procedure. By repeating this cycle, the intervention procedure is continuously adjusted in the intervention process to seek a most suitable intervention solution for the subject, and an optimal intervention effect is achieved.

A nasogastric tube connector device includes an annular connector body for detachably engaging a through hole of a respirator mask having an inner peripheral surface defining a space, and a fixed member having a first concave surface and two side surfaces cooperating with the inner peripheral surface to define an opening of the space for passing of a nasogastric tube therethrough. A first plug member is detachably inserted through the opening into the space, and includes a second concave surface cooperating with the first concave surface to define a main tube hole communicating with the space. A second plug member is detachably inserted into the main tube hole to sealingly close the opening.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side of the plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

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.

A system for vaccinating swine according to one embodiment includes a housing having an open first end and an open opposite second end. The housing has a pair of side walls that are angled and non-parallel to one another such that at the second end only a single piglet can exit at one time. The system also includes a vaccination station for individually vaccinating piglets. The vaccination station is located between the pair of side walls in a region thereof that is sized to only permit one piglet to stand between the side walls. The vaccination station includes at least one sensor that detects the presence of the one piglet within the vaccination station and at least one spray nozzle positioned within the vaccination station such that a vaccine dose discharged therefrom is directed upwardly into facial areas of the piglet effectively.
