Description

Technical Field

[0001] The utility model relates to the technical field of nasal oxygen tubes, in particular to a high-flow nasal oxygen tube for patients. Background Art

[0002] In the ICU ward, many patients have difficulty breathing and need to rely on oxygen supply equipment to assist in breathing. The existing high-flow nasal oxygen tube includes a bell mouth for connecting to the oxygen supply equipment, a nasal plug, and a connecting tube connecting the bell mouth and the nasal plug.

[0003] When using most of the conventional high-flow nasal oxygen cannulas, the nasal plug is directly inserted into the nose and the connecting tube is fixed around the patient's ears without protecting the patient's face and nose. Therefore, if the cannulas are directly inserted into the patient's nose and worn on the patient's head for a long time, it will cause discomfort to the patient, resulting in reduced comfort for the patient when using the cannulas. Moreover, when using the cannulas, the connecting tube is only connected to the connecting head without being effectively fixed. Therefore, when the patient's head swings, the connecting tube is easily separated from the connecting head. If the nursing staff fails to find out in time, it is easy to cause hypoxia in the patient, which may cause serious medical accidents. For this reason, we propose a high-flow nasal oxygen cannula for patients. Utility Model Content

[0031] Working principle:

[0032] When in use, first slide the two ends of the connecting tube 5 in the corresponding card slots 4 through the provided card blocks 6, so that the two ends of the connecting tube 5 enter the inner cavity of the connecting head 2 and the oxygen supply equipment respectively, so that the connecting tube 5 is preliminarily connected with the connecting head 2 and the oxygen supply equipment. After the preliminary connection is completed, the two vertical ends of the U-shaped positioning block 8 can be inserted into the inner cavity of the two slots 7, and the card blocks 6 are tightly connected with the card slots 4, so that the connecting tube 5, the connecting head 2 and the oxygen supply equipment can be doubly effectively fixed, which can prevent the patient's head from shaking during use, and the nursing staff will not find it in time, resulting in the patient's hypoxia and causing serious medical accidents. After the two ends of the connecting tube 5 are connected to the connecting head 2 and the external oxygen supply equipment, the device can be put on the head of the patient who needs to use it through the wearing ring 15. At the same time, after wearing it on the head of the patient in use, By using the soft ring 16 and the protective strip 17 made of rubber material, the wearing ring 15 can be protected when it is worn on the patient's head to prevent the wearing ring 15 from directly strangling the patient's head, thereby improving the patient's comfort during use. Then, the two nasal inlet tubes 10 are inserted into the patient's nose. After the two nasal inlet tubes 10 enter the patient's nose, the patient's nose can be protected to prevent the nasal inlet tubes 10 from directly entering the patient's nose, causing wear to the nose and causing discomfort to the patient; and by snapping the U-shaped mounting block 19 into the positive mounting groove 18, the lip protection pad 20 is connected to the circular ring 1, and the lip protection pad 20 can be fitted with the patient's lips after the two nasal inlet tubes 10 enter the patient's nose, thereby preventing the patient's lips from being crushed during use.
