Patient interface systems

Abstract

A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the patient's nares; a pair of strips configured to be connected to opposite sides of the patient interface structure; and adhesive configured to secure the patient interface structure in sealing engagement with the patient's nares. The adhesive maybe provided on the strips, and the strips are configured to be adhered to sides of the patient's nose by the adhesive. Another patient interface system includes a first component including adhesive ona first side and hook or loop fastener material on a second side. The patient interface structure includes a second component including a corresponding loop or hook fastener material configured to engage the corresponding hook or loop fastener material of the first strip. A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure including a pair of nasal prongs or pillows configured to sealingly engage the patient's nares; and at least one spring configured to bias the nasal prongs or pillows outwards into engagement with the naresof the patient.

The present invention also relates to patient interface systems that may include one or more adhesives and / or patient interface positioning and / or support structures that support the patient interface in engagement with the patient. Background technique [0003] The use of positive airway pressure (PAP) to treat sleep-disordered breathing (SDB) such as obstructive sleep apnea (OSA) is disclosed in US Patent 4,944,310. Treatment with a PAP, which may be continuous positive airway pressure (CPAP), involves the use of a patient interface attached to the patient's face for sup...

AI Technical Summary

Problems solved by technology

However, patients may find it difficult to adapt to the current interface

For example, once a mask including a headgear and gas delivery hose is installed on a patient to provide the required seal, the patient may have difficulty falling asleep in a familiar, comfortable position

Although masks provide a seal and a defined pressure, patients may be reluctant to use a mask due to concerns about sleeping comfortably while wearing it

This can cause patients to forego treatment
