Abstract
The present technology is directed to a respiratory pressure therapy system, that includes a plenum chamber pressurisable to a therapeutic pressure above ambient air pressure, a seal-forming structure to form a seal with an entrance to the patient's airways to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use, a positioning and stabilising structure constructed and arranged to provide an elastic force to hold the seal-forming structure in a therapeutically effective position on the patient's head, a blower configured to generate the flow of air and pressurise the plenum chamber to the therapeutic pressure, the blower having a motor, the blower being connected to the plenum chamber such that the blower is suspended from the patient's head and the axis of rotation of the motor is perpendicular to the patient's sagittal plane, and a power supply configured to provide electrical power to the blower.

A respiratory pressure therapy (RPT) system comprising: a plenum chamber pressurisable to a therapeutic pressure of at least 6 cmH O above ambient air pressure; a seal-forming structure constructed and arranged to form a seal with a region of a patient’s face at or surrounding an entrance to the patient’s airways such that a flow of air at said therapeutic pressure is delivered to at least the entrance to the patient’s nares, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patient’s respiratory cycle in use; a positioning and stabilising structure constructed and arranged to provide an elastic force to hold the seal-forming structure in a therapeutically effective position on the patient’s head, the positioning and stabilising structure comprising a tie, a lateral portion of the tie being constructed and arranged to overlie a region of the patient’s head superior to the otobasion superior in use, and a superior portion of the tie being constructed and arranged to overlie a region of the patient’s head in a region of the parietal bone in use, wherein the positioning and stabilising structure has a non-rigid decoupling portion; a blower configured to generate the flow of air at said therapeutic pressure and pressurise the plenum chamber to the therapeutic pressure, the blower having a motor, the blower being connected to the plenum chamber such that in use the blower is suspended from the patient’s head and an axis of rotation of the motor is generally perpendicular to the patient’s sagittal plane; and a power supply configured to provide electrical power to the blower.
2. The RPT system of claim 1, wherein the seal-forming structure is constructed such that no part thereof enters the patient’s mouth in use.
3. The RPT system of claim 1 or claim 2, wherein the seal-forming structure does not extend internally of the patient’s airways. ResMed Ref: P1285NZ2 / JAWs Ref: 506229NZDIV1
4. The RPT system of any one of claims 1 to 3, wherein the plenum chamber does not cover the eyes in use.
5. The RPT system of any one of claims 1 to 4, wherein the blower is contained at least partially within the plenum chamber.
6. The RPT system of claim 5, wherein the plenum chamber comprises at least one housing portion.
7. The RPT system of claim 6, wherein the at least one housing comprises two housing portions that are at least partially separable to allow the blower to be removed from the plenum chamber.
8. The RPT system of claim 7, wherein the two housing portions are joined at one side in a clamshell arrangement to allow the plenum chamber to be opened and closed.
9. The RPT system of claim 7 or claim 8, further comprising a sealing structure between the two housing portions.
10. The RPT system of any one of claims 1 to 9, wherein at least one attachment structure extends from the plenum chamber to attach the positioning and stabilising structure to secure the RPT system to the patient’s head in use.
11. The RPT system of any one of claims 1 to 10, wherein the plenum chamber comprises a plenum chamber outlet through which the flow of air at said therapeutic pressure passes from the blower to at least the entrance to the patient’s nares in use.
12. The RPT system of claim 11, wherein the seal-forming structure is connected to the plenum chamber at the plenum chamber outlet.
13. The RPT system of any one of claims 1 to 12, wherein the plenum chamber comprises a port that is configured to be connected to at least one of a pressure transducer and a supplemental gas source.
14. The RPT system of any one of claims 1 to 13, wherein the seal-forming structure comprises: ResMed Ref: P1285NZ2 / JAWs Ref: 506229NZDIV1 a pair of nasal puffs, or nasal pillows, each nasal puff or nasal pillow being constructed and arranged to form a seal with a respective naris of the nose of the patient; a seal-forming structure that forms a seal in use on a nose bridge region or on a nose-ridge region of the patient’s face and that forms a seal in use on an upper lip region of the patient’s face; or a seal-forming structure that forms a seal in use on a nose bridge region or on a nose-ridge region of the patient’s face and that forms a seal in use on a chin- region of the patient’s face.
15. The RPT system of any one of claims 1 to 14, further comprising a heat and moisture exchanger (HME) within the plenum chamber that is positioned in the flow of air at said therapeutic pressure and downstream of the blower.
16. The RPT system of any one of claims 1 to 15, wherein the RPT system does not include a vent such that in use the patient exhales through the blower in opposition to the flow of air at said therapeutic pressure and the patient’s exhalate exits the RPT system through an inlet of the blower.
17. The RPT system of any one of claims 1 to 16, wherein the power supply comprises a battery, the battery further comprising at least one electrochemical cell.
18. The RPT system of claim 17, wherein the battery is supported by the positioning and stabilising structure on a region of the patient’s head adjacent to the parietal bone.
19. The RPT system of claim 18, wherein the battery is contained within the positioning and stabilising structure.
