Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a universal nasopharyngeal ventilation tube. Background Art

[0002] Nasopharyngeal airways are mainly used for patients who have difficulty breathing due to tongue root retraction caused by various reasons, in order to keep the patient's airway open; they can also be used to remove oral and pharyngeal secretions in patients who have clenched jaws or cannot cooperate with oral suction for various reasons. However, for patients who need to keep the nasopharyngeal airway in place for a long time, the existing nasopharyngeal airway is prone to dry throat and nasopharyngeal discomfort after long-term use because the inhaled gas is not humidified. In winter, the cold gas does not properly warm the nasal mucosa, causing maladaptive shock to the patient, which is not conducive to the patient's recovery.

[0003] In addition, the main causes of snoring or obstructive sleep apnea syndrome are upper airway stenosis and tongue root fall. At present, the main clinical treatments for obstructive sleep apnea syndrome are wearing non-invasive ventilators and surgical treatment. Surgery is relatively traumatic and has limited effects, which is difficult for most patients to accept. The wearing of home non-invasive ventilators is relatively cumbersome, and patients are prone to abnormal leakage when changing their positions at night. Moreover, wearing them for a long time may cause facial discomfort, thus affecting the patient's sleep, psychology, and work status. Therefore, we specially propose a universal nasopharyngeal ventilation tube to solve the above problems. Summary of the invention

Compared with the traditional ventilation tube, the air entering the throat can be kept moist and warm through the air vent 30, and the air in the air chamber 60 is inflated to make the soft rubber outer tube 21 expand and deform outward, so that a gap is generated between the end of the cover 50 and the opening of the liquid storage tank 40, and then the medicine in the liquid storage tank 40 can be released to act on the nasal mucosa, so that the medicine can be delivered, which is more practical. In addition, the outward convex arch of the cover 50 can also play a preliminary role in positioning the soft rubber outer tube 21, while also ensuring comfort in use.

[0027] In this embodiment, multiple liquid storage tanks 40 and air chambers 60 are provided along the circumference of the soft rubber outer tube 21. The multiple liquid storage tanks 40 arranged circumferentially form a liquid storage unit. Multiple liquid storage units are provided along the length direction of the soft rubber outer tube 21 so that after inflation and opening the cover 50, the medicine can be released in the entire coverage area of ​​the soft rubber outer tube 21.
