Method for targeted application of active agents to a target surface including the steps of: (a) capturing an image of the target surface; (b) transforming the image into a digital geometric representation of the target surface; (c) forming an applicator mask having an applicator surface with a three-dimensional shape corresponding to the target surface; (d) disposing the active agent on the applicator surface of the applicator mask; (e) disposing the applicator mask on the target surface so that the active agent is in contact with the target surface; and (f) removing the applicator mask from the target surface while leaving at least some of the active agent in contact with the target surface.

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 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.

The subject matter described herein includes a mask for use in providing oxygen or nebulized medicaments. The mask includes at least two straps and a plurality of apertures defined along two sides of the mask. The apertures are configured for receiving the at least two straps at more than two positions along a length of the mask. The mask includes at least one exhalation port and an inhalation port for receiving the oxygen or nebulized medicaments. In operation an oxygen delivery tube and reservoir bag are connected to the inhalation port.

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.

Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material. Therapeutic agents may be formulated with a gel, for example, a hydrogel, a hydrocolloid, alginate, methyl cellulose, gelatin or any other gels for sustained-release and enhanced usability. A wound fluid collection device including an absorbable material may interface with the wound treatment device to facilitate the collection and disposal of wound material.

A method for forming an applicator comprises steps of: creating a digital geometric representation of the structure, the target structure having a flatness ratio; forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface; and disposing an active agent upon the target structure contacting surface of the applicator.

Face soaking devices (devices) may include a vessel and a vessel neck gasket. The vessel may be configured to hold a liquid to submerge a face of a user or a portion thereof. The vessel neck gasket may be (removably) joined to the vessel. The vessel neck gasket may be configured to comfortably accommodate a portion of the user's neck. The devices may include a breathing apparatus that may be in removable contact with: the vessel, with a head rest subassembly, and/or with the user. The breathing apparatus may be configured to permit the user to breathe while the user's face may be submerged within the liquid. When the vessel may be filled with the liquid to at least a sufficient level, the user may soak the face or the portion thereof, such that the skin being soaked receives a benefit.
