Description

Throat mist device for preventing and treating throat edema
Technical Field
The utility model relates to the field of medical appliances, in particular to a throat mist sprayer for preventing and treating throat edema.
Background
Aerosol inhalation is a direct administration method using respiratory tract and lung as target organs, has the advantages of quick effect, high local drug concentration, less dosage, convenient application, less systemic adverse reaction and the like, and has been used as an important treatment means for respiratory system related diseases. While aerosol inhalation devices are drug delivery devices that convert a drug into an aerosol form and inhale through the oral (or nasal) cavity, for example, small-volume nebulizers are a special aerosol generating device that causes a drug solution or suspension to form an aerosol for inhalation by a patient and deposition in the respiratory tract and lungs for the purpose of treating a disease.
In addition, mechanical ventilation is a very important rescue treatment for intensive care units, and tracheal intubation can cause mechanical irritation of the throat and trachea, leading to inflammation and oedema of the throat and trachea, which is the most common complication of tracheal intubation, is the main cause of airway obstruction after extubation requiring re-intubation, and serious laryngeal oedema can also endanger patient life. Statistics of related researches show that more than 136 patients with cannulae for 24 hours are subjected to bronchoscopy 6 hours after tube drawing, 74 patients with laryngeal oedema with different degrees can occur, the incidence rate is 54%, and a common method for treating the laryngeal oedema is aerosol inhalation.
During invasive ventilation, the atomization inhalation device is connected with a breathing machine pipeline through a T-shaped pipe, and aerosol reaches the lung through an endotracheal tube pipeline by means of breathing of a patient to play a therapeutic role. However, since the opening of the tracheal cannula is positioned in the trachea and the airway is closed by the balloon in order to avoid air leakage, the atomized inhalation through the tracheal cannula cannot reach the epiglottis, and therefore, the prevention and treatment of the laryngeal edema cannot be performed. If the aerosol inhalation device is placed in the oral cavity, the airway is closed by the trachea cannula air bag, no gas flows, the aerosol medicine cannot directly reach the epiglottis position, and the fixed trachea cannula device needs to be withdrawn due to the large diameter of the mouth of the aerosol inhaler, so that the risk of falling off a pipeline exists.
The prior throat sprayer and the disposable atomization inhaler which are frequently used in the field all have respective defects: the throat sprayer achieves the aim of spraying medicine in a pneumatic mode, but the solution cannot form an aerosol form, and can only treat the part in the spraying range locally, and the mucous membrane of a patient is easy to damage; because the intubated patient does not have the action of inhaling, aerosol can not be inhaled into the airway through the buccal mouth, the face mask or the nasal insert, and the disposable atomization inhaler can not achieve the effect of preventing and treating the laryngeal edema of the intubated patient.
