[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 2 The utility model provides a technical solution: a nasal catheter that fits the face, comprising a nasal tube 1, a ventilation hose 2 and an oxygen inhalation head 3, the two ends of the nasal tube 1 are integrally formed with the ventilation hose 2, the side of the nasal tube 1 is provided with two oxygen inhalation heads 3 for inserting into the nasal cavity, and the oxygen inhalation heads 3 are arranged obliquely, and the end of the oxygen inhalation head 3 away from the nasal tube 1 is arranged in a spherical structure;

[0023] In specific implementation, by inserting the spherical end of the oxygen inhalation head 3 into the nasal cavity, it can play a role in buffering the compression of the nasal cavity and prevent the nasal cavity from being squeezed and painful. At the same time, the two oxygen inhalation heads 3 are tilted to clamp the nasal cavity and prevent the nasal catheter from slipping off.

[0024] See also Figure 5 and Figure 6 The nasal tube 1 is composed of an arched tube 101 and a straight tube 102, the arched tube 101 is located between the two straight tubes 102, one end of the oxygen inhalation head 3 is butted at the junction of the arched tube 101 and the straight tube 102, and the oxygen inhalation head 3 is connected to the nasal tube 1;

[0025] A guide ring 301 is fixed to one end of the oxygen inhalation head 3 that is plugged into the nasal tube 1. A crescent block 302 is arranged inside the guide ring 301. The lower edge of the guide ring 301 is blocked by the crescent block 302 to ensure that the normal oxygen absorption of the oxygen inhalation head 3 is not affected when water vapor flows along the lower wall surface inside the arch tube 101. A through hole 303 is provided between the guide ring 301 and the crescent block 302, and the guide ring 301 protrudes from the inner wall surface of the nasal tube 1.

[0026] In a specific implementation, an arched tube 101 is arranged between two straight tubes 102. When the ventilation hose 2 introduces oxygen, the oxygen is sent into the oxygen inhalation head 3 along the nasal tube 1. When the patient exhales, part of the exhaled gas will enter the nasal tube 1 along the oxygen inhalation head 3, so that the exhaled gas will produce water vapor when encountering the cold nasal tube 1. By fixing the guide ring 301 at the end of the oxygen inhalation head 3 and protecting the inner wall of the guide ring 301 by the crescent block 302, the flowing water vapor is prevented from passing through the through hole 303 into the oxygen inhalation head 3, thereby ensuring that the patient can inhale oxygen more smoothly.

[0027] See also Figure 1-Figure 4 The outer side of the ventilation hose 2 is provided with an anti-slip ring 4, and a viscose pad 5 is fixed on one side of the anti-slip ring 4; a cushion 6 for adhering to the face is provided on one side of the anti-slip ring 4, and the cushion 6 is made of silicone material, and a docking port 7 abutting against the viscose pad 5 is provided in the middle of one side of the cushion 6. By bonding the cushion 6 to the anti-slip ring 4 in different directions through the viscose pad 5, the angle of the cushion 6 can be changed to facilitate adaptation to the patient's face; a groove 8 is provided on the side of the cushion 6 away from the docking port 7, and the cushion 6 and the groove 8 constitute a suction cup structure.

[0028] During specific implementation, when the ventilation hose 2 is placed on the patient's face, the anti-slip ring 4 is put on the ventilation hose 2, and the adhesive pad 5 on one side of the anti-slip ring 4 is adhered to the docking port 7 on the surface of the cushion 6. The cushion 6 can be applied to the patient's face through the groove 8, so that the nasal catheter can fit more comfortably on the patient's face. The suction cup structure formed by the cushion 6 and the groove 8 can ensure that the cushion 6 has an anti-slip effect when applied to the face, making it convenient for the cushion 6 to fit closely to the face, and preventing the ventilation hose 2 from causing pressure marks on the face.

[0029] In summary, by inserting the spherical end of the oxygen inhalation head 3 of the nasal catheter into the nasal cavity and supplying oxygen through the ventilation hose 2, the ventilation hose 2 delivers oxygen into the nasal tube 1, and then the nasal tube 1 delivers oxygen along the oxygen inhalation head 3 into the patient's nasal cavity to provide oxygen supply care for the patient. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
