Problems solved by technology

Forces that are too low can cause air leaks, defeating the purpose of the pressure support system, and causing skin discomfort and waking sleeping patients with unpleasant noises
Additionally, air can leak into the patient's eyes, causing eye irritation
The problems described above reduce patient tolerance and compliance with medical procedures utilizing face masks

Embodiment Construction

[0034] figure 1 The first embodiment of the patient interface device 10 is shown. For example, the patient interface device 10 can be used to treat obstructive sleep apnea (OSA). The patient interface device 10 includes a sealing assembly 12 and an attachment assembly 14. The sealing assembly 12 generally covers the nose and mouth of the patient 16 and delivers a flow of breathable gas to the patient 16. Alternatively, the sealing assembly 12 may cover the entire face or only the nose of the patient 16. In another alternative embodiment, the sealing assembly 12 may also include a cannula or pillow inserted into the nose of the patient 16.

[0035] The sealing assembly 12 is attached to the patient's face 18 using the attachment assembly 14. In this embodiment, the attachment assembly 14 includes a helmet strap 20 and a forehead support 22. The helmet straps 20 provide flexibility between the head of the patient 16 and the sealing assembly 12 and the forehead support 22, respe...

Abstract

The present invention relates to a patient interface device (10) comprising a sealing assembly (12) for delivering a flow of breathable gas to a patient (16),an attachment assembly (14) for attaching the sealing assembly (12) to a patient's face (18) and a force limitation unit (26)for limiting a force between the patient interface device(10) and the patient's face (18) to a maximum force when the patient interface device (10) is applied to the patient (16), the force limitation unit (26) comprising a first and a second coupling element (27, 28) constituting a self-releasing force-fitted coupling for transmitting the force from the first to the second coupling element (27, 28) and for interrupting the force-fit between said two coupling elements (27, 28) when the force exceeds the maximum force.

Description

Invention field [0001] The present invention relates to a patient interface device including a sealing assembly for delivering a flow of breathable gas to a patient and an attachment assembly for attaching the sealing assembly to the face of the patient. Background technique [0002] More and more patients suffer from obstructive sleep apnea or obstructive sleep apnea syndrome (OSA). OSA is usually caused by obstruction of the upper airway. It is characterized by repeated pauses in breathing during sleep and is usually associated with a decrease in blood oxygen saturation. These pauses in breathing (called apneas) usually last 20 to 40 seconds. The obstruction of the upper airway is usually caused by the reduced muscle tone of the body that occurs during sleep. The human airway consists of a collapsible wall of soft tissue, and thereby obstruct breathing during sleep. The tongue body tissue moves towards the back of the throat during sleep and thereby blocks the air passage. ...
