Abstract

The disclosure is directed to an example of a device configured to be in fluid communication with an article. The device includes an element configured to contact the article to form a variable compression interface between the element and the article. The device also includes a seal disposed on the element and at the variable compression interface. The seal is configured to reduce an amount of unwanted fluid leakage at the variable compression interface. An example seal includes a filter media configured to trap unwanted particles attempting to pass through the variable compression interface. In one example, the variable compression interface can be included within a heat and moisture exchange (HME) unit.

Description

Background technique [0001] Clinicians often use ventilators or breathing circuits to assist patients with breathing, or to otherwise treat respiratory conditions. Ventilators and breathing circuits provide mechanical assistance to patients who are struggling to breathe on their own and are used to deliver gases and medications. The breathing circuit may be coupled to or include a positive pressure source, such as a container with pre-compressed gas or a ventilator, to deliver pressurized gas flow to the patient's lungs. When the overpressure is released, the patient will exhale due to the elasticity of the lungs (in many devices the order may be reversed, ie the patient's attempt to exhale during the overpressure will cause the overpressure to release). Sometimes the breathing circuit can be a simple, manually operated bag-valve mask that fits over the patient's nose, mouth, or both. Some breathing circuits are more complex and may include a set of additional breathing comp...
