The present invention discloses a patient interface having an adaptive system. The adaptive system includes a forehead pressure diffusing portion (S1), a cheek buffering portion (S2) and a connecting portion (S3, 320). The forehead pressure diffusing portion (S1) is disposed in a frame module (300). The cheek buffering portion (S2) is disposed in a cushion module (100). The connecting portion (S3, 320) is positioned between the forehead pressure diffusing portion (S1) and the cheek buffering portion (S2). The connecting portion (S3, 320) is configured to transmit pressure between the forehead pressure diffusing portion (S1) and the cheek buffering portion (S2). Thus, when a patient 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.
