A kind of nebulizing inhalation device for ventilator

technical field

The utility model relates to the field of medical equipment, in particular to an atomization inhalation device for a ventilator.

Background technique

Respiratory system diseases are mainly characterized by dyspnea, hypoxia, chest tightness and shortness of breath. Non-invasive ventilator is an effective instrument for clinical treatment of patients with respiratory system diseases. In addition to observing various parameters of the ventilator when using non-invasive ventilation, it is also necessary to do Good airway management must ensure that patients can cough and expectorate spontaneously during non-invasive ventilation, and keep the airway open. Therefore, while using non-invasive ventilators for patients, patients will also be treated with anti-inflammatory, asthma and phlegm reduction, and atomization inhalation. treat. However, there is currently no nebulizer inhaler that can be connected to a non-invasive ventilator in clinical practice, which brings treatment difficulties to some critically ill patients who cannot be weaned off, and increases the risk of poor sputum expectoration and airway blockage.

Some critically ill patients in the respiratory department need to use endotracheal intubation to keep the airway open, and use an invasive ventilator to assist breathing after intubation. However, after tracheal intubation, the normal humidification, heating, filtering and coughing functions of the upper respiratory tract will disappear, and the defense function will be weakened. Sputum crusts form on the respiratory tract, causing airway blockage, increasing sputum expectoration difficulties and hypoxia, causing or aggravating respiratory tract infections, leading to re-intubation. Therefore, it is very important to strengthen the airway care of patients with endotracheal intubation. Adequate and appropriate airway humidification can effectively reduce the complications of artificial airway and increase the success rate of weaning. However, there is no device for tracheal intubation atomization and inhalation at present. In the prior art, tracheal drops are usually used to humidify the airway. When using tracheal drops, the moisturizing liquid cannot be mixed with secretions and enters the airway with coughing. The liquid in the tract can further transfer the sputum to the small airways and lung lobes, which will aggravate the pulmonary infection, and the guidelines for airway humidification have clearly stipulated that airway drips are not recommended for airway humidification; The heated humidifier configured by the ventilator is difficult to meet the clinical humidification needs.
