[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0022] like Figure 1As shown, the present embodiment provides a nasal oxygen inhalation device suitable for the nasopharyngeal airway, comprising a nasal oxygen inhalation tube 1, a miniature artificial nose 2, a fixing device 3 and a temperature and humidity regulating device 4. The nasal oxygen inhalation tube 1 is a hollow long tube with a moderate hardness and softness, and is preferably made of medical polyvinyl chloride material, which can reduce its damage to the nasal mucosa and will not twist and fold in the body to cause stenosis of the lumen. Specifically, the nasal oxygen inhalation tube 1 comprises a first end 11 and a second end 12, and the first end 11 can be inserted into the nasopharyngeal airway, and the second end 12 is connected to the oxygen supply machine, so that oxygen can be supplied to the patient through the nasal oxygen inhalation tube 1 to relieve the problem of upper respiratory tract obstruction. However, the insertion of the nasal oxygen tube 1 will cause discomfort to the patient, resulting in complications such as nausea, vomiting, and nasal mucosal damage, and the patient is prone to problems such as dry nose and nasal pain when inhaling oxygen at a large flow rate. Therefore, it needs to be improved. Firstly, a miniature artificial nose 2 is arranged at the first end 11 of the nasal oxygen tube 1. The texture and structure of the miniature artificial nose 2 are close to those of the human nasal cavity, so that the damage to the mucosa of the nasopharyngeal airway when the nasal oxygen tube 1 is inserted can be effectively reduced, and the occurrence of complications can be reduced; secondly, the nasal oxygen tube 1 is placed in an ideal position and fixed by the fixing device 3, which can reduce the occurrence of complications such as nausea, vomiting, and aspiration, and improve the patient's use satisfaction. Specifically, the fixing device 3 includes a fixing clip 31 and a fixing bag 32. The fixing clip 31 can be movably mounted on the nasal oxygen tube 1 to adjust the insertion length of the nasal oxygen tube 1 according to the length of the patient's nasopharyngeal airway. The fixing bag 32 is connected to the fixing clip 31 and can be movably mounted on the outer wall of the nasal oxygen tube 1. After the fixing clip 31 is fixed, the fixing bag 32 is fixed to the nostril to prevent the nasal oxygen tube 1 from shifting or falling off, which affects the oxygen supply effect. It should be noted here that the inner diameter and length of the nasopharyngeal airway of different patients are not the same, so the selection of the thickness of the nasal oxygen tube 1 and the determination of the insertion length are very important. First, the appropriate thickness can ensure that the nasal oxygen tube 1 can be inserted into the nasopharyngeal airway, and prevent oxygen from being lost from the gaps in the nasopharyngeal airway and affecting the oxygen concentration; secondly, placing the nasal oxygen tube 1 in an ideal position and fixing it can reduce the occurrence of complications such as nausea, vomiting, and aspiration.Thirdly, the temperature and humidity of the input oxygen are adjusted by the temperature and humidity regulating device 4 to avoid complications such as dry nose and nasal pain when a large oxygen flow rate is input. Specifically, the temperature and humidity regulating device 4 is a closed bottle body, and a first through hole and a second through hole are provided at relative positions at the upper end of the closed bottle body, the first through hole is used to connect the second end 12 of the nasal oxygen inhalation tube 1, and the second through hole is used to connect the oxygen supply machine; liquid is stored in the closed bottle body for humidifying the oxygen flowing through; a thermometer is provided on the top of the closed bottle body for measuring the temperature in the closed bottle body, and the oxygen is input into the nasal oxygen inhalation tube 1 after passing through the temperature and humidity regulating device 4. The temperature and humidity regulating device 4 can heat and humidify the oxygen flowing through, ensuring that the patient is not prone to complications such as dry nose and nasal pain when inhaling oxygen at a large flow rate, and providing a comfortable medical experience while ensuring the safety of the patient; in addition, a control valve is provided in the temperature and humidity regulating device 4 for adjusting the oxygen flow and humidity.

[0023] Furthermore, a scale line is provided on the first end 11 of the nasal oxygen tube 1, so as to facilitate accurate adjustment of the insertion length of the nasal oxygen tube 1 and further reduce the occurrence of complications such as nausea and vomiting.

[0024] Furthermore, the fixing device 3 also includes a plurality of anti-pressure sore pads 33, which are made of rubber material. Spacer rings are arranged on the side walls of the fixing bag 32 to relieve pressure on the nasal cavity to prevent the risk of pressure sores in elderly patients, thin patients, etc. who use it for a long time.

[0025] When in use, according to the specific situation of the patient, choose a nasal oxygen tube of appropriate thickness, then fix the miniature artificial nose on the first end of the nasal oxygen tube, put the fixing device on the nasal oxygen tube, fix the second end of the nasal oxygen tube on the first through hole of the temperature regulating device, then insert the miniature artificial nose into the patient's nasopharyngeal airway, start the oxygen supply machine to supply oxygen to the patient, and solve the patient's hypoxia problem in time, then determine the insertion length of the nasal oxygen tube according to the patient's specific situation, position the fixing clip to the corresponding scale, and fix the fixing bag to the nose end to avoid shaking of the nasal oxygen tube during use, and adjust the temperature and humidity regulating device according to the patient's feelings during oxygen inhalation.

[0026] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be performed without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
