Method and apparatus for securing a patient interface to a patient's face

1. A breathing assistance system, comprising:

a patient interface configured to interface with a patient to communicate gas received from a gas delivery apparatus to the patient; and

a gas conduit system for communicating gas from the gas delivery apparatus to the patient via the patient interface;

a securing system including a generally tubular structure open at least at one end, the generally tubular structure adapted to at least substantially cover a generally cylindrical strip of the patient's head that extends vertically between the patient's forehead and the patient's mouth and circumferentially around the patient's head, the generally tubular structure formed from mesh or netting material,

wherein the mesh or netting material of the tubular structure covers the patient's eyes;

wherein at least a portion of the generally tubular structure is elastic such that at least a portion of the generally tubular structure can be stretched over the patient's head; and

wherein the securing system is configured to secure the patient interface against the patient's face.

2. A breathing assistance system according to claim 1 , wherein the gas conduit system includes one or more gas conduits.

3. A breathing assistance system according to claim 1 , wherein the patient interface comprises a facial cushion.

4. A breathing assistance system according to claim 1 , wherein the patient interface comprises a nasal pillow.

5. A breathing assistance system according to claim 1 , wherein the generally tubular structure of the securing system comprises a plurality of filaments defining interstices between adjacent filaments.

6. A breathing assistance system according to claim 1 , wherein the generally tubular structure of the securing system is relatively elastic in a first direction and relatively inelastic in a second direction.

7. A breathing assistance system according to claim 1 , wherein the securing system terminates at a bottom end in an elastic band or hem adapted to be positioned around the patient's neck, the elastic band or hem formed from a tighter weave of elastic material or from a different elastic material than the generally tubular structure.

8. A breathing assistance system according to claim 7 , wherein the generally tubular structure of the securing system comprises a strap at least partially integrated into the generally tubular structure at a location spaced apart from the band or hem at the bottom end of the generally tubular structure.

9. A breathing assistance system according to claim 1 , wherein the gas conduit system includes at least one of a ventilation tube connected to the patient interface, a connection system connected between the patient interface and the gas delivery apparatus, and a coupler for connecting the ventilation tube to the connection system.

10. A method for securing a patient interface to a patient, the method comprising:

positioning the patient interface relative to at least one of the nose and mouth of the patient, the patient interface configured to communicate gas received from a gas delivery apparatus to the patient; and

stretching a securing system comprising an at least partially elastic, generally tubular structure to cover a substantial portion of the patient's head, the generally tubular structure adapted to at least substantially cover a generally cylindrical strip of the patient's head that extends vertically between the patient's forehead and the patient's mouth and circumferentially around the patient's head, the generally tubular structure formed from mesh or netting material, wherein the mesh or netting material of the generally tubular structure covers the patient's eyes.

11. A method according to claim 10 , wherein the positioning comprises coupling the patient interface to the gas delivery apparatus.

12. A method according to claim 10 , wherein the stretching comprises lengthening filaments in the generally tubular structure of the securing system to extend the securing system around the patient's head.

13. A method according to claim 10 , wherein the securing system includes a net having a plurality of filaments.
