Embodiment Construction

[0154] In general, the present invention relates to respiratory gas delivery and sampling systems, gas sampling systems, gas sampling interfaces, and gas sampling tips that can be used to sample exhaled and / or exhaled gas from a patient. A gas sampling system includes a respiratory gas monitor in fluid communication with a gas sampling interface that includes a gas sampling tip of the present invention. The gas sampling interface includes a gas sampling conduit, and the gas sampling end is located at the free end of the conduit. The gas sampling interface may be configured to allow selective positioning of the gas sampling tip at or in the patient's mouth or nostrils. The sampling tip includes at least one inlet for receiving exhaled or exhaled gas from the patient. The sampling tip may also be configured to include a shield or structure that helps prevent fluids, such as moisture or bodily fluids, from entering the sampling tip. Additionally or alternatively, the sampling t...

Abstract

There is provided a respiratory gas delivery and sampling system, a gas sampling system, a gas sampling interface and a gas sampling tip that may be used to sample exhaled and / or expired gases from apatient, particularly from a patient who is apnoeic and / or who is receiving high flow respiratory therapy. The gas sampling system comprises a respiratory gas monitor in fluid communication with the gas sampling interface, which comprises the gas sampling tip of the invention. The gas sampling interface comprises a gas sampling conduit and the gas sampling tip is located at a free end of the conduit. The gas sampling interface may be configured to allow the gas sampling tip to be selectively positioned at or in the mouth or a nare of the patient's nose.

Description

technical field [0001] The present disclosure generally relates to respiratory gas therapy. More specifically, the present disclosure relates to an interface for capturing exhaled and / or exhaled gases, such as carbon dioxide, near a patient's nose or mouth when respiratory gases are supplied to the patient by a respiratory apparatus. In use, the interface comprises or is typically fluidly connected to a gas sampling conduit which is fluidly connected to a respiratory gas monitor. This interface may be particularly useful when measuring exhaled and / or expired gases from a patient receiving a high flow of breathing gas. Background technique [0002] In a medical setting, it is common practice to monitor the concentration of gas exhaled and / or exhaled by a patient using a gas sampling system that includes a respiratory gas monitor connected to a gas sampling interface that includes a gas A sampling conduit for conveying exhaled and / or exhaled gas from a patient to a respirato...
