Abstract
The present invention discloses a patient interface having an adaptive system, a respiratory mask and a cushion module adapted with the adaptive system. The adaptive system includes a forehead pressure diffusing portion, a cheek buffering portion and a connecting portion. The forehead pressure diffusing portion is disposed in a frame module. The cheek buffering portion is disposed in a cushion module. The connecting portion is positioned between the forehead pressure diffusing portion and the cheek buffering portion. The connecting portion is configured to transmit pressure between the forehead pressure diffusing portion and the cheek buffering portion. Thus, when a user wears a mask or other devices with the adaptive system, a force received by the face of the user could be automatically and appropriately distributed, further improving comfort of the wearer.
