Abstract

A continuous positive airway pressure (CPAP) system in combination with a device for positioning a breathing apparatus over a breathing orifice in the head of a person, the person having an occipital lobe and an axis of symmetry, the device including an occipital anchor for anchoring against the head of the person beneath the occipital lobe of the person. The device further including a forward anchor for anchoring against a forward portion of the person'"'"'s head. A spring connector connects the forward anchor and the occipital anchor, and biases the occipital anchor against the head of the person beneath the occipital lobe and the forward anchor against the corresponding portion of the person'"'"'s head so as to attach the device to the person'"'"'s head. The occipital anchor, the forward anchor and the spring connector are substantially aligned along the axis of symmetry of the person'"'"'s head. The mount is connected to the spring connector for mounting the apparatus so as to locate the apparatus over the orifice.

Claims

1. A method of treating sleep apnea utilizing a breathing mask and a mask attachment device having an occipital anchor adapted to fit against the head of a person beneath their occipital lobe, a forward anchor adapted to fit against the person'"'"'s head at a forward anchoring position selected from the group consisting of a first portion of the person'"'"'s head proximally surrounding a breathing orifice and a region selected from the group consisting of a top portion of the person'"'"'s head and a forehead portion of the person'"'"'s head, a biasing structure extending from the occipital anchor to the forward anchor, and a mounting member connecting the mask to the biasing structure, said method comprising the steps of

positioning the occipital anchor about the person'"'"'s occipital lobe, and the forward anchor against the corresponding portion of the person'"'"'s head, such that the breathing mask is in communication with at least one breathing orifice of the person and the occipital anchor, the forward anchor, and the biasing structure are substantially aligned along an axis of symmetry of the person'"'"'s head, the biasing structure biasing the occipital anchor against the person'"'"'s occipital lobe, the forward anchor against the corresponding portion of the person'"'"'s head, and the breathing mask against the portion of the person'"'"'s head proximally surrounding the breathing orifice;

connecting the mask to a continuous positive airway pressure (CPAP) system; and

providing respirator gas from the CPAP system to the person via the mask to prevent apnea while the person sleeps.

2. The method of

claim 1

, wherein the positioning step includes positioning the forward anchor on a top portion of the person'"'"'s head rearwardly of the person'"'"'s forehead.

3. The method of

claim 1

, wherein the positioning step includes positioning the forward anchor against a portion of the person'"'"'s head proximally surrounding the breathing orifice.

4. The method of

claim 1

, wherein the mask attachment device is secured to the person'"'"'s head without straps utilizing substantially only the occipital anchor, the forward anchor, and the biasing structure.

5. The method of

claim 1

, further comprising the step of securing the mask attachment device to the person'"'"'s head using straps that extend from the occipital anchor to the forward anchor.

6. The method of

claim 1

, further comprising the step of removing expired gas containing carbon dioxide using a vent formed in the mask.

7. The method of

claim 3

, further comprising the step of stabilizing the mask attachment device using a compliant sling disposed between the mask attachment device and the person'"'"'s head and having opposite ends connected to forward and rear portions of the biasing structure.

8. In combination, a continuous positive airway pressure (CPAP) system for providing CPAP to a person via a mask to prevent sleep apnea, and a device for holding the mask in place over an orifice in the person'"'"'s head while the person sleeps, the device comprising

an occipital anchor adapted to fit against the head of the person about the occipital lobe of the person;

a forward anchor adapted to fit against a corresponding portion of the person'"'"'s head at a forward anchoring position selected from the group consisting of a first portion of the person'"'"'s head proximally surrounding the orifice and a region located from a top portion of the person'"'"'s head to a forehead portion of the person'"'"'s head;

a biasing structure connecting the forward anchor and the occipital anchor, the biasing structure adapted to bias the occipital anchor against the head of the person beneath occipital lobe and to bias the forward anchor against the corresponding portion of the person'"'"'s head so as to attach the device to the person'"'"'s head, wherein the occipital anchor, the forward anchor and the biasing structure are adapted to be substantially aligned along the axis of symmetry of the person'"'"'s head; and

a mounting member connected to the biasing structure for mounting said apparatus so as to locate the apparatus over said orifice.

9. The combination of

claim 8

, wherein the mask further comprises a vent sized so that CPAP flushes the system of exhaled gases between breaths.

10. The combination of

claim 8

, wherein the occipital anchor, forward anchor, biasing structure and mounting member are essentially the only means for holding the breathing mask in place over an orifice in a person'"'"'s head while the person sleeps.

11. The combination of

claim 8

, wherein the device further comprises a side strap connecting the occipital anchor with the forward anchor.
