Embodiment Construction

[0334] Various embodiments are described with reference to the figures. Throughout the drawings and the specification, like reference numerals may be used to designate the same or similar components, and redundant descriptions thereof may be omitted.

[0335] Connectors according to embodiments described herein are particularly suitable for use in respiratory systems such as CPAP or high flow breathing gas systems such as high flow systems for use in anesthesia procedures. Respiratory systems where the connector can be especially useful are CPAP, BiPAP, High Flow Therapy, Variations of High Flow Therapy, Low Flow Air, Low Flow O 2 Delivery, bubble CPAP, apnea high flow (ie high flow to the anesthetized patient), invasive ventilation and non-invasive ventilation. Additionally, connectors as described herein may be used in systems other than respiratory systems. Connectors according to embodiments described herein are particularly suited for use with pressure relief or regulat...

Abstract

The present invention relates to a pressure relief device and components thereof. A connector has a connector body with an inlet and an outlet defining a gas flow passage therebetween. The connector body has an overlap portion that is configured to overlap with a portion of a second connector when connected. An access passage extends through the overlap portion to the gas flow passage.

Description

technical field [0001] The present disclosure relates to pressure relief devices for medical systems for delivering gas to and / or from a patient, in particular flow and / or pressure compensating pressure relief devices, diaphragm components and connectors thereof. Background technique [0002] A breathing gas supply system provides gas for delivery to the patient. A breathing gas supply system typically includes a fluid connection between the gas supply and the patient. This can include the suction tube and patient interface. Such systems include many different components to ensure that the gas is properly delivered to the patient. Many parts are single-use parts that are disposed of after each use, while others are multi-use parts. In some cases, multiple use parts are preferred. In some cases, it is necessary to connect single-use components to multiple-use components. However, this can cause problems if the single-use and multi-use components are incorrectly or accide...
