Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

A patient interface device (10) includes a patient sealing assembly (60) including a cushion (70), and a frame member (80) coupled to the cushion, and an adjustable forehead support assembly (200) provided at the distal end (120) of the frame member. The adjustable forehead support assembly includes an adjustment mechanism (202) coupled to a forehead cushion (204), wherein the adjustment mechanism includes a forehead cushion support member (212) having a base portion (216) coupled to the forehead cushion and an vertical/upright rotatable wheel member (214). Rotation of the wheel member causes movement of the frame member and the cushion relative to the forehead cushion.

A mask system for delivering air pressurized above atmospheric pressure to the airways of a patient to treat sleep disordered breathing (SDB) by continuous positive airway pressure (CPAP) may include a mask having a cushion configured to form a seal with the patient's nose; two inlet conduits, each of the two inlet conduits configured to extend from a position superior to the patient's head and along a corresponding side of the patient's head, and each of the two inlet conduits being in fluid communication with a corresponding side of the mask to deliver pressurized air to the mask; a first vent arrangement configured to be positioned superior to the patient's head in use and configured to discharge gas to atmosphere during therapy; and a second vent arrangement configured to be positioned inferior to the first vent arrangement in use and configured to discharge gas to atmosphere during therapy.

Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

A mask assembly for delivering breathable gas to a patient may include a patient interface structured to engage the patient's face and provide a seal, a headgear arrangement to support the patient interface in a desired position on the patient's face, and an audio unit provided to at least one of the patient interface and the headgear arrangement. The audio unit may be operable to selectively generate at least one sound.

A mask assembly includes a mask frame including a lower portion and a neck extending from the lower portion, a cushion provided to the mask frame and adapted to contact a patient's face, a forehead support assembly provided to the neck of the mask frame, the forehead support assembly including a forehead support and a forehead pad provided to the forehead support, and an elbow assembly provided to the mask frame. The neck includes a pair of side walls spaced apart from one another along an entire length of the neck, the side walls providing an open space therebetween along the entire length of the neck that opens towards a front side of the mask assembly. The pair of side walls comprise an upper converging section wherein the pair of side walls converge towards one another in a downward direction.

A portable patient interface system includes a frame, a cushion coupled to a first side of the frame, a collapsible faceplate coupled to a second side of the frame opposite the first side, and a longitudinally collapsible hose structured to be in fluid communication with the collapsible faceplate and the cushion.

A patient interface device (8) includes a patient sealing assembly (12) including a cushion (14) and a frame member (16), and an adjustable forehead support assembly (26) provided at the distal end (24) of the frame member. The assembly includes an adjustment mechanism (28) coupled to a forehead cushion (30), the adjustment mechanism including a housing (32), a forehead cushion support member (52) having a base portion (58) and an elongated post member (60) extending from the base portion and received within the housing, and a locking member (54, 56) structured to be selectively coupled to the elongated post member. In the locked condition, the locking member engages the elongated post member and prevents the elongated post member from moving relative to the housing, and in the unlocked condition the locking member does not engage the elongated post member such that the elongated post member and the housing are freely linearly movable with respect to one another.

A lung isolation system configured for selective isolation and ventilation of the lung in conjunction with a standard endotracheal tube. The system includes an expandable bronchial isolation tube comprising a collapsible nitinol frame, a bifurcated adapter, and a steerable optical stylet.

Skin-contact products with a transpiration function such as medical devices or medicinal products, of which face masks, aspirators, ventilators, breast pumps or wound dressings are examples are described especially a skin-contact product with a transpiration function with an improved microclimate at a patient interface material-skin contact area. In an embodiment a material system is described that comprises a hydrophobic silicone base material and a hydrophilic silicone material that is combined with the hydrophobic base material.
