Description

Technical Field

[0001] The utility model belongs to the technical field of medical monitoring devices, and particularly relates to a closed sputum suction tube with an end-tidal carbon dioxide monitoring function. Background Art

[0002] In clinical surgical monitoring, end-tidal carbon dioxide, as a non-invasive monitoring technology, has been considered the sixth basic vital sign in addition to body temperature, respiration, pulse, blood pressure, and arterial oxygen saturation. Intraoperative end-tidal carbon dioxide monitoring can directly reflect the patient's respiratory rate and respiratory parameters. In the absence of other vital sign parameters such as blood gas, the observation of end-tidal carbon dioxide can directly know the patient's respiratory form and condition. It is the golden indicator for judging the patient's respiratory form. By measuring the end-tidal carbon dioxide concentration to reflect the patient's ventilation effect, ventilation abnormalities can be discovered in time to reduce the risk of respiratory depression.

[0003] The commonly used probe design for end-tidal carbon dioxide monitoring is currently fixed on the anesthesia threaded tube connector or the breathing filter of the pressure oxygen mask. It adopts an unconventional fixing method, which is inconvenient to use. The end-tidal carbon dioxide monitoring probe connected to the patient end often falls off, causing false alarms of the monitor, increasing misjudgments, and easily causing accidental damage to the device. In the prior art, the patent number is CN202223603560.5, the publication number is CN219595536U, and the patent name is a utility model patent for a multifunctional nasal catheter with end-tidal carbon dioxide collection. The nasal catheter is provided with an end-tidal carbon dioxide collection structure, but this type of structure is not suitable for being set on a suction tube, so it is necessary to combine the prior art for improved design.
