Embodiment Construction

[0047] The respiratory mask according to the present invention is very advantageous, mainly because the elastic sealing member improves the seal between the respiratory mask and the patient’s face, and can also enable a single size mask to be used in a larger size range (compared to what has been possible so far Situation) face. Respiratory masks are particularly advantageous when used for oxygen and / or aerosol therapy.

[0048] First reference Figure 1 to 4 , The figure shows a breathing mask according to the present invention, which is suitable for delivering gas to a wearer, such as a patient. The breathing mask includes: a mask body 10 made of a suitable strong and relatively rigid plastic material, such as polypropylene; and a sealing member 20 made of styrene-ethylene-butylene-styrene based (SEBS) thermoplastic elastomer.

[0049] The breathing mask is manufactured using the so-called two-shot injection molding method. In particular, the mask body 10 is firstly injection ...

Abstract

There is provided a respiratory mask (10;100;200) for delivering an inhalation gas to the airways of a wearer, the respiratory mask comprising a body (10) of generally concave shape and having a peripheral edge, the body being adapted to provide a cavity (11,12) in use about the mouth and nose of a wearer such that the inhalation gas can be inhaled by the wearer from the cavity. The body has an inlet port (13) that is engageable with a supply of inhalation gas and in communication with the cavity. The respiratory mask includes a resilient seal formation (20) depending from at least a portion of the peripheral edge. The resilient seal formation comprises both an inwardly (22) and outwardly (28) depending lip portion relative to the peripheral edge of the body. The inwardly depending lip portion (22) is arranged in use to pass closely beneath the mandible of a wearer (38) having a relatively smaller facial dimension (Y) and the outwardly depending lip portion (28) is arranged to pass closely beneath the mandible of a wearer (42) having a relatively larger facial dimension (Y'). The mask may accommodate a range of facial dimensions whilst still retaining an effective seal.

Description

Technical field [0001] The present invention relates to a breathing mask suitable for delivery of gas for inhalation by a patient, and more particularly (though not exclusively) to a mask suitable for use in therapy. Background technique [0002] Respiratory masks are used to supply inhaled gas and possibly aerosolized liquid (for example, medicine in solution) to the airway of the patient. Generally, gas is supplied to a breathing enclosure defined by a breathing mask and the patient's face, and the patient inhales the inhaled gas from the breathing enclosure. Ordinary masks usually have an inlet and an outlet for inhaling gas, through which the exhaled gas escapes the breathing mask. [0003] Ordinary breathing masks are relatively flexible and are usually formed as an integral part of polyvinyl chloride (PVC) material. The integral part defines a cavity and usually has a peripheral edge that rotates outwards. When assembled on a patient, the peripheral edge presses against the...
