Problems solved by technology

[0013] However, the mask is still uncomfortable
There are many differences between human faces and it is very difficult to develop a limited number of masks that can fit each individual
Customization of the mask is a reasonable solution to this problem, but at present, the associated cost and production time prevent this

Embodiment Construction

[0041] The present invention provides a cushion arrangement for a patient interface in communication with a patient's nose or nose and mouth, and the present invention provides a patient interface utilizing the cushion. A shaped structure is in contact with the liner. The shaped structure includes a heat shrinkable material, which can be customized for the end user, and which applies pre-compression or expansion to the pad.

[0042] The discrepancy between the user's facial shape and the pad geometry can cause discomfort or cause air leakage, or both. By pressing the patient interface device (ie, mask components) very tightly against the face, air leakage can be eliminated at the expense of high pressure points (a process that causes erythema), thus reducing patient / mask compliance.

[0043] The aim of the present invention is to reduce the pressure generated on the face by utilizing a tailor-made process, which means that the pressure-maintaining function is obtained at leas...

Abstract

A cushion arrangement for a patient interface (for communicating with the nose or the nose and mouth of a patient) comprises a cushion and a shaping structure in contact with the cushion. The shaping structure comprises a thermo-shrink material, and the local dimension of the themo-shrink material determines a level of local compression or expansion of the cushion. The shaping structure enables the cushion to be customised for the end user.

Description

field of invention [0001] The present invention relates to a patient interface for delivering gas to and / or from the airway of a user and to a method of making the patient interface. The invention also relates to cushions for such patient interfaces. Background technique [0002] There are many situations where it is necessary or desirable to deliver a flow of breathing gas non-invasively to a patient's airway, ie, without catheterizing the patient's airway or surgically inserting an endotracheal tube into their esophagus. For example, it is known to ventilate a patient using a technique known as non-invasive ventilation. It is also known to deliver continuous positive airway pressure (CPAP) or variable airway pressure that varies with the patient's breathing cycle to treat medical conditions such as sleep apnea syndromes, especially obstructive sleep apnea (OSA ). [0003] Non-invasive ventilation and pressure support therapy involves placement of a patient interface dev...
