[0002] In the medical field, especially for patients with respiratory diseases, those in intensive care, and those undergoing anesthesia or surgery, real-time monitoring of carbon dioxide levels is crucial. Traditional carbon dioxide monitoring devices often require separate consumables, are relatively complex to operate, and may not integrate well with nasal cannulas, causing inconvenience to medical staff and patients. Utility Model Content

[0004] The technical solution adopted by this utility model is as follows: a nasal oxygen cannula that can monitor carbon dioxide includes a main tube, a partition is provided inside the main tube, the partition divides the inside of the main tube into a closed oxygen supply chamber and a closed monitoring chamber, a first cannula and a second cannula are provided at intervals along the central axis of the main tube on the outside of the main tube, and an oxygen supply port and a monitoring port are respectively opened at both ends of the main tube.

[0005] Furthermore, the first conduit is disposed outside the oxygen supply chamber, and the first conduit is connected to the oxygen supply chamber.

[0006] Furthermore, the second conduit is positioned between the oxygen supply chamber and the monitoring chamber, and the second conduit connects the oxygen supply chamber and the monitoring chamber respectively.

[0007] Furthermore, the second conduit has a second partition inside, which divides the second conduit into a monitoring tube and an oxygen supply tube, and the second partition is connected to the first partition.

[0008] Furthermore, the length of the monitoring tube is greater than the length of the oxygen supply tube, and the length of the oxygen supply tube is shorter than the length of the conduit.

[0009] Furthermore, the monitoring tube is connected to the monitoring cavity, and the oxygen supply tube is connected to the oxygen supply cavity.

[0010] Furthermore, the oxygen supply port is connected to the oxygen supply device via a conduit, and the monitoring port is connected to the monitoring device via a conduit.

[0011] Furthermore, the diameter of the oxygen supply port is larger than the diameter of the monitoring port.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] By linking the first partition in the main tube and the second partition in the second conduit, it is possible to conveniently and in real time monitor carbon dioxide levels while providing oxygen to the patient. Furthermore, the length difference between the monitoring tube, the oxygen supply tube, and the first conduit prevents oxygen from interfering with carbon dioxide collection and improves the collection efficiency of carbon dioxide flow.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0022] like Figure 1-2As shown in -3-4, a nasal oxygen cannula that can monitor carbon dioxide includes a main tube 1. The main tube 1 is provided with a partition 2, which divides the interior of the main tube 1 into a closed oxygen supply chamber 3 and a closed monitoring chamber 4. The outer side of the main tube 1 is provided with a conduit 5 and a conduit 6 at intervals along the central axis of the main tube 1. The two ends of the main tube 1 are respectively provided with an oxygen supply port 7 and a monitoring port 8.

[0023] Among them, catheter 1 5 is located outside the oxygen supply chamber 3 and is connected to the oxygen supply chamber 3. Catheter 2 6 is located between the oxygen supply chamber 3 and the monitoring chamber 4. Catheter 2 6 is connected to the oxygen supply chamber 3 and the monitoring chamber 4 respectively. The length of the monitoring tube 10 is greater than the length of the oxygen supply tube 11, and the length of the oxygen supply tube 11 is shorter than the length of catheter 1 5. The monitoring tube 10 is connected to the monitoring chamber 4, and the oxygen supply tube 11 is connected to the oxygen supply chamber 3. The oxygen supply port 7 is connected to the oxygen supply device through a catheter. The monitoring port 8 is connected to the monitoring device through a catheter. The diameter of the oxygen supply port 7 is greater than the diameter of the monitoring port 8. Through the linkage of the partition 1 2 in the main tube 1 and the partition 2 9 in the catheter 2 6, it is possible to conveniently and in real time monitor the carbon dioxide level while providing oxygen to the patient. The length difference between the monitoring tube 10, the oxygen supply tube 11 and the catheter 1 5 prevents oxygen from interfering with the collection of carbon dioxide and improves the collection efficiency of carbon dioxide flow.

[0024] In practical use, the oxygen supply module continues to supply oxygen to the patient through the conduit 5 and oxygen supply tube 11, which are connected to the oxygen supply chamber 3. Exhaled gas enters the monitoring chamber 4 through the monitoring tube 10 and is then introduced into the monitoring module to accurately measure the carbon dioxide concentration in the patient's exhaled gas. By using a nasal oxygen cannula that can monitor carbon dioxide, medical staff can understand the patient's respiratory status and the expulsion of carbon dioxide in the body more timely and accurately. This helps to detect possible respiratory abnormalities, insufficient ventilation, or over-ventilation in the patient in a timely manner, so as to take corresponding measures for adjustment and treatment, improve the quality of medical care, and ensure the safety of the patient.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
