Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oxygen delivery tubes, in particular to an oxygen delivery tube with a nasopharyngeal airway. Background Art
[0002] With the introduction of the concept of comfortable medical care, painless upper gastrointestinal endoscopic diagnosis and treatment has been widely used and promoted in clinical practice; the use of anesthetics or sedatives can reduce operational complications and increase patient comfort, but it is prone to airway obstruction, respiratory depression, hypoxemia, and even apnea. Especially in some obese patients, due to anatomical factors such as limited neck back extension and pharyngeal fat accumulation, anesthesia and sedation can cause severe hypoxemia, endangering the life and health of patients;
[0003] Currently, conventional nasal cannula oxygen therapy is used clinically to reduce the incidence of hypoxemia. However, this method cannot avoid hypoxemia caused by upper airway obstruction, and the upper airway obstruction often needs to be manually relieved during use. Methods for relieving upper airway obstruction include insertion of a nasopharyngeal airway, etc. Although the nasopharyngeal airway can relieve upper airway obstruction, it does not have the ability to supply oxygen and requires additional oxygen supply equipment.

[0009] An oxygen outlet is provided in the nasopharyngeal ventilation tube.
[0010] According to the utility model of an oxygen supply tube with a nasopharyngeal airway, the mounting head is used to connect the oxygen supply end of the oxygen supply tube to the oxygen supply device; the oxygen supply tube body is used to transport the oxygen in the oxygen supply device to the oxygen outlet through the oxygen supply tube body, and the oxygen outlet is arranged in the nasopharyngeal airway, and the nasopharyngeal airway is placed in the patient's body, so the oxygen transported to the nasopharyngeal airway will naturally enter the patient's body through the nasopharyngeal airway; at the same time, relevant clinical operations can be performed on the patient through the nasopharyngeal airway, so that the patient's nasopharyngeal airway can be opened. While preventing the patient's upper respiratory tract obstruction, it can also supply oxygen to the patient's body through the nasopharyngeal airway, and the oxygen outlet of the oxygen supply tube is fixed on the inner wall of the nasopharyngeal airway, which can reduce the damage to the patient's respiratory mucosa caused by the direct impact of the oxygen supply airflow; when in use, when the patient may have the risk of upper respiratory tract obstruction such as tongue prolapse, pre-oxygen anesthesia induction is performed, the nasopharyngeal airway is lubricated, and the nasopharyngeal airway is pushed down through the nasal cavity along the palatine bone plane to the posterior wall of the nasopharynx. After placement, the installation head is connected to the oxygen supply equipment for oxygen inhalation.
[0011] According to some embodiments of the present invention, an auxiliary fixing clip is further included, which is arranged on the oxygen supply tube body and is clamped to the oxygen supply tube body through a clamping ring. By setting the auxiliary fixing clip, when using the device, the auxiliary fixing clip is put on one ear of the patient, which can prevent the movement of the patient from causing the nasopharyngeal ventilation tube placed in the patient's body to be displaced along with the movement of the oxygen supply tube, thereby causing the nasopharyngeal ventilation tube to fall from the patient's body.
[0012] According to some embodiments of the utility model, a sealing rubber ring is provided at one end of the mounting head away from the oxygen supply tube body; since one end of the mounting head is connected to the oxygen supply outlet of the oxygen supply equipment, a sealing rubber ring is provided at the contact point between the mounting head and the oxygen outlet to ensure that oxygen leakage does not occur.

[0015] According to some embodiments of the utility model, the length of the nasopharyngeal ventilation tube is 15 cm, and the diameter of the nasopharyngeal ventilation tube is 6.0 mm-8.5 mm. In clinical practice, the diameter of the nasopharyngeal ventilation tube used by adult males is 7.5 mm-8.5 mm, and the diameter of the nasopharyngeal ventilation tube used by adult females is 6.0 mm-7.0 mm. Therefore, the diameter range of the nasopharyngeal ventilation tube designed by this device is 6.0 mm-8.5 mm, and the length of the nasopharyngeal ventilation tube generally used in clinical medicine is 15 cm.
[0016] According to the utility model, an oxygen delivery tube with a nasopharyngeal airway has the following beneficial effects:
[0017] (1) While relieving the patient's upper airway obstruction, the patient should be effectively supplied with oxygen through oxygen supply equipment and oxygen tubes to avoid the failure of the oxygen provided to be effectively exchanged with the patient due to upper airway obstruction;
[0018] (2) While relieving the patient's upper airway obstruction, the patient's upper airway secretions can also be suctioned through the nasopharyngeal airway, and the suction process will not interrupt the oxygen supply.
