Abstract
Patient interface devices (8) structured to deliver a flow of breathing gas to an airway of a patient include a member (16) structured to contact and adhere to a face of the patient responsive to the patient interface being donned by the patient, the member having a contact surface and an adhesive layer (34) provided on the contact surface.
Claims20
A patient interface device structured to deliver a flow of breathing gas to an airway of a patient, comprising:
- a member structured to contact and adhere to a face of the patient responsive to the patient interface device being donned by the patient, the member having a contact surface including a base region, an apex region located opposite the base region, a first side region, and a second side region located opposite the first side region, the member having an adhesive layer provided on the contact surface, wherein the adhesive layer has a pull-off strength limit value throughout the adhesive layer that is ≤40 kPa and an adhesive shear strength limit value throughout the adhesive layer that is ≤27 kPa, wherein a first thickness of the adhesive layer in the base region is ≥0.1 mm and ≤0.5 mm and wherein a second thickness of the adhesive layer in each of the apex region, the first side region and the second side region is ≥0.5 mm and ≤1.0 mm.
A patient interface device structured to deliver a flow of breathing gas to an airway of a patient, comprising:
- a nasal cushion structured to contact a nose of the patient and deliver the flow of breathing gas to the nose;
- an attachment member coupled to and surrounding at least a portion of the nasal cushion, the attachment member being structured to contact and adhere to a face of the patient responsive to the patient interface device being donned by the patient, the attachment member having a contact surface and an adhesive layer provided on the contact surface, wherein the adhesive layer has a pull-off strength limit value throughout the adhesive layer that is ≤40 kPa and an adhesive shear strength limit value throughout the adhesive layer that is ≤27 kPa, wherein a first thickness of the adhesive layer in a first region thereof is ≥0.1 mm and ≤0.5 mm and wherein a second thickness of the adhesive layer in a second region thereof is ≥0.5 mm and ≤1.0 mm.
