Meanwhile, the first air filter can also prevent germs existing in the carbon dioxide monitor from entering the patient body through the first catheter, so that the infection of the patient is caused. 2. The luer connector and the male connector are adopted to realize the direct connection between the carbon dioxide monitor, so that the direct connection is convenient and quick. 3. The luer connector female connector is adopted to realize connection with the carbon dioxide detection tube, so that the length of the carbon dioxide detection tube in production can be saved, the whole length is greatly shortened, and the production cost is reduced. 4. The effect of the first air filter being arranged close to the end-tidal carbon dioxide connector is to reduce the influence of the first air filter on the patient's expiration. 5. The second air filter is arranged in the second conduit and is used for filtering fine particles in the oxygen, so that the influence of the fine particles in the oxygen on a patient is reduced. 6. The second air filter is arranged in the second conduit close to the oxygen connecting joint, so that the influence of the second air filter on oxygen inhalation of a patient can be reduced to the greatest extent.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
An end-tidal carbon dioxide collection nasal oxygen cannula with filter as shown in fig. 1 includes a nasal aspirator 100 consisting of an end-tidal nasal cannula 110 and an end-tidal nasal cannula 120. The respiratory nasal tube and the oxygen inhalation nasal tube are not communicated. One end of the nose tube 110 extends into the nose of the patient, and the other end is connected with a first conduit 200, and an end of the first conduit, which is far away from the nose tube, is connected with an end-tidal carbon dioxide connector 300 to realize connection with a carbon dioxide detector. At the same time, a first air filter 400 is connected in the first conduit, which separates the patient at both ends of the first conduit from the capnography. After the gas exhaled by the patient passes through the first air filter 400, germs in the exhaled gas are filtered by the first air filter 400, so that the carbon dioxide monitor is prevented from being polluted. In contrast, when the patient inhales, the air entering the respiratory tract of the patient via the capnography and the first conduit is also filtered by the first air filter 400, thereby effectively preventing germs possibly existing in the capnography from entering the patient via the patient inhalation. At the same time, one end of the oxygen inhalation nasal tube 120 extends into the other nasal tube of the patient, while the other end of the oxygen inhalation nasal tube is connected with a second conduit 500, and the end of the second conduit far away from the nasal tube of the oxygen inhalation nasal tube is connected with an oxygen connecting joint 600 which can be detachably connected with an oxygen source. Preferably, the patient is mixed with fine particles in the oxygen during the oxygen inhalation process, and the influence on sensitive patients is great. To exclude this, a second air filter 700 is also connected to the second conduit 500. In order to reduce the influence of the second air filter on oxygen inhalation of the patient, the second air filter is disposed close to the oxygen connection joint 600.
In order to reduce the influence of the first air filter on the respiration of the patient, the first air filter 400 is disposed near the end tidal carbon dioxide connector 300. In addition, during long-term use, the air with the pathogenic agent repeatedly passes through the first air filter due to the patient's breathing, and thus the filtering effect of the first air filter is reduced. In order to reduce the economical burden of the patient while securing the effective filtering effect of the first air filter, the first air filter 400 is detachably coupled to the first duct 200. In particular, the first air filter may be in the form of a luer fitting or a cannula for detachable connection to the first conduit. When the first air filter is used for a certain time, which results in a reduced filtering capacity, the medical staff can perform the replacement of the first air filter.
It should be further noted that, to facilitate the direct connection with the capnometer, the end-tidal carbon dioxide connector 300 employs a luer male connector adapted to the capnometer.
Example 2
The difference between this embodiment and embodiment 1 is that the end-tidal carbon dioxide connector 300 is in the form of a female luer connector. The purpose of adopting this kind of joint structure is that a section of carbon dioxide detecting tube is often connected to the existing carbon dioxide monitor, and the free end of the carbon dioxide detecting tube adopts a male luer connector, so that in order to adapt to the carbon dioxide detecting tube, the terminal calling carbon dioxide connector 300 adopts a female luer connector. By the above-mentioned mode, the length of the first conduit 200 can be greatly shortened in the production process, thereby reducing the production cost.
