Problems solved by technology

[0016] However, there is still room for improvement
One of the main technical challenges is the technical design and arrangement of such actuators inside the pad elements
It is particularly challenging to design and arrange said actuators in such a way that static pressure points can be effectively avoided

Embodiment Construction

[0048] figure 1 An exemplary embodiment of a patient interface for delivering a flow of breathable gas to a patient is shown. Therein, the patient interface itself is denoted as a whole by the reference number 10.

[0049] In this embodiment, patient interface 10 is designed as a full face mask covering the mouth and nose of patient 12 . It should be noted that patient interface 10 may alternatively be designed as a nasal mask, a mouth mask, or a full face mask without departing from the scope of the present invention.

[0050] Patient interface 10 includes a cushion element 14 and a housing 16 . Cushion element 14 is designed to contact the face of patient 12 and provide an airtight seal at the interface between the patient's face and patient interface 10 . Pad element 14 typically comprises a soft material, like silicone or any other rubber or suitable elastic material. The shell 16 provides a flexible, semi-rigid or rigid support structure for holding the cushion elemen...

Abstract

The present invention relates to a cushion element (14) for a patient interface (10) for providing a flow of breathable gas to a patient (12), wherein the cushion element (14) comprises a face-contacting layer (32) for contacting a face of the patient (12) during use of the cushion element (14); and a multi-layer responsive structure (34) which is covered by the face-contacting layer (32). The responsive structure (34) comprises a plurality of actuators (38, 40) for moving the face-contacting layer (32), wherein said plurality of actuators (38, 40) comprises first actuators (38) belonging to a first group of actuators and second actuators (40) belonging to a second group of actuators. Each of the first and the second actuators (38, 40) comprises an electrode (44, 46). The electrodes (44) of the first actuators (38) are arranged in one or more first layers (50), and wherein the electrodes (46) of the second actuators (40) are arranged in one or more second layers (52), wherein the one or more first and second layers (50, 52) are arranged above each other. The electrodes (44) of the first actuators (38) are, with respect to a first axis (42) transverse to the one or more first and second layers (50, 52), arranged spatially offset relative to the electrodes (46) of the second actuators (40) such that the electrodes (44) of the first actuators (38) do not overlap the electrodes (46) of the second actuators (40) when being viewed along the first axis (42).

Description

field of invention [0001] The present invention relates to a cushion element for a patient interface for providing a flow of breathable gas to a patient. In particular, the present invention relates to an improved cushioning element with respect to more effectively avoiding red marks on the patient's face. Still further, the present invention relates to patient interface and pressure support systems utilizing such cushion elements. Background technique [0002] A patient interface (eg, a mask covering the mouth and / or nose) is used to deliver gas to the patient. Such gases (eg, air, purified air, oxygen, or any modification of oxygen) are provided to the patient via the patient interface, either under pressure or not. [0003] Long-term attachment of such a patient interface to the patient is necessary, or at least desirable, for a variety of chronic disorders and diseases. [0004] A non-limiting example of such a disease is obstructive sleep apnea or obstructive sleep a...
