A non-invasive ventilation system may include a nasal interface. The nasal interface may include a left outer tube with a left distal end adapted to impinge a left nostril, at least one left opening in the left distal end in pneumatic communication with the left nostril, and a left proximal end of the left outer tube in fluid communication with ambient air. The left proximal end of the left outer tube may curve laterally away from a midline of a face. A right outer tube may be similarly provided. One or more left jet nozzles may direct ventilation gas into the left outer tube, and one or more right jet nozzles may direct ventilation gas into the right outer tube. The jet nozzles may be in fluid communication with the pressurized gas supply.

A cushion member for a patient interface device that includes a main body portion including a plurality of chambers and a self-sealing cap portion coupled to the main body portion. The cap portion covers each of the chambers and forms a plurality of membrane members, with each membrane member being positioned over and sealing a respective one of the chambers. The cap portion is made of a self-sealing material such that that each of the membrane members is structured to self-seal responsive to having a needle inserted through and pulled out of the membrane member. Also, an apparatus and a method for selectively adjusting the internal pressure of the chambers of such a cushion.

A system for reducing airway obstructions of a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle, and at least one spontaneous respiration sensor in communication with the control unit for detecting a respiration effort pattern and a need for supporting airway patency. The system may be open to ambient. The control unit may determine more than one gas output velocities. The more than one gas output velocities may be synchronized with different parts of a spontaneous breath effort cycle, and a gas output velocity may be determined by a need for supporting airway patency.

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

Disclosed is a mask cushion for a full face mask with a single sealing lip for sealing contact with the face of a user.

A breathing mask for use in administering inhalable medications to a patient in need of an inhaled drug is provided. The mask disclosed herein is particularly useful for use with very young children. The mask is made from a flexible molded plastic silicone or elastomeric material, and has an anthropometrically/anatoinically/ergonomically contoured shape to provide a good seal, a comfortable fit, and minimal dead space within the mask. The airway is aligned with nose. There may be an orifice for use with a soother device to calm a child using the mask. Also provided is a visual flow indicator to provide an indication of the quality of the seal of the mask on the face.

A headgear or headgear segments are manufactured to shape thereby producing little or no waste material. Techniques such as knitting, braiding, crocheting, and 3D printing can be used produce the headgear.

An interface includes a mask. The mask includes a frame and a seal supported by the frame. Headgear is connected to the mask. The interface includes at least one of (i) an adjustment mechanism that can be set to a use length for a loop defined by the mask and the headgear; and (2) a break-fit assembly that can selectively lengthen the loop defined by the mask and the headgear and return to the use length.

The present invention provides a wearable medical support for delivery of a treatment to the nose of a subject comprising: a nose mask formed from a heat moldable sheet of thermoplastic material, said nose mask comprises an aperture dimensioned to fit the nose of the subject, said aperture is flanked by two flaps whereby each flap is configured to be in contact with at least part of a lateral side of the nose; and a device configured to close fit said aperture, said device is provided at one end with an opening for receiving the nose and at the other end with at least one coupling suitable to be connected to one or more tubes for delivery of the treatment to the nose. The present invention further provides a sheet of heat moldable thermoplastic material for molding a mask directly on a subject's nose.

A respiration mask includes an upper portion connectible to a source of gas. A lower portion is connected to the upper portion. The lower portion is adapted to facilitate a leak resistant seal between the upper portion and a person's nose and mouth by surrounding the person's nose and mouth, when in use. The respiration mask also includes a deformation element incorporated into the lower portion. The deformation element establishes a plurality of sealing barriers between the lower portion and the person's nose and mouth. The upper portion encompasses a first material with a modulus of elasticity between 150 ksi and 200,000 ksi. The deformation element encompasses a second material exhibiting a hardness below one of 40 Shore A or 80 Shore OO and tear a resistance greater than 5 lbf/in. The plurality of sealing barriers establishes the leak resistant seal for a pressure up to 60 mm Hg.
