Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide collection, specifically a multi-purpose carbon dioxide collection nasal oxygen tube. Background Technology

[0002] End-tidal carbon dioxide (ETC) is a relatively new non-invasive detection technology that is increasingly used in surgical anesthesia monitoring. It is highly sensitive, monitoring not only ventilation but also circulatory function and pulmonary blood flow. It has become an indispensable routine monitoring method in anesthesia. Normal breathing must be ensured for effective ETC monitoring. The sampling process typically involves an oxygen delivery tubing, a carbon dioxide collection tubing, a nasal cannula, and connectors.

[0003] Existing technology, such as the carbon dioxide collection nasal oxygen tube disclosed in Chinese Patent Publication No. CN222110660U, includes a nasal oxygen tube, input and output pipes, and a mask; the input and output pipes include an oxygen delivery pipe for delivering oxygen and an output pipe for collecting carbon dioxide, which are independent and isolated from each other; the nasal oxygen tube includes a nasal oxygen pipe connected to the oxygen delivery pipe for delivering oxygen to the periphery of the nasal cavity or oral cavity, and a collection pipe connected to the output pipe for inserting into the nasal cavity to collect exhaled carbon dioxide; the outlet of the nasal oxygen pipe is located on the nasal oxygen tube.

[0004] Although existing sampling devices also use two sets of pipes for oxygen supply and carbon dioxide collection during the sampling process, the existing technology cannot easily limit the pipes during carbon dioxide sampling. Secondly, many patients breathe through their mouths while under anesthesia, and the existing technology does not effectively collect the exhaled air from the mouth. Or, the oral breathing in the existing technology is usually integrated with the nasal oxygen tube, and it cannot distinguish between the cavity and the nostrils during the sampling process.

[0007] By adopting the above technical solution, oxygen can be conveniently provided to patients, and carbon dioxide exhaled by patients can be collected through carbon dioxide collection tubing.

[0008] The present invention is further configured such that the oxygen inlet connector is an inner conical connector and the carbon dioxide connector is a Luer connector.

[0009] Preferably, the oxygen inlet connector can be easily connected to an external oxygen supply device, and the carbon dioxide connector can be connected to a carbon dioxide detector.

[0010] The present invention is further configured such that the oxygen supply pipe and the carbon dioxide collection pipe are firmly bonded together.
