Description

Ventilator Oxygen-Driven Nebulization Drug Delivery Device

technical field

The invention relates to the technical field of medical machinery, in particular to an oxygen-driven atomized drug delivery device for a ventilator.

Background technique

Oxygen-driven nebulization inhalation is a kind of jet nebulization inhalation method, the amount of liquid medicine is small, the nebulization time is short, it can produce ideal aerosol volume and nebulized particles, and increase the settlement of aerosol particles in the lungs. Oxygen is the driving force, which can quickly spread the particles to the lower respiratory tract, and has a wide contact area with the airway, and its effect is direct. The existing atomization inhalation method is to hold the inhaler with the mouth, inhale through the mouth (medicine liquid), and exhale through the nose. The method is not suitable. In the acute stage of the onset, unaccustomed breathing methods will increase the patient's respiratory distress. In addition, because the respiratory state of patients with chronic type II respiratory failure is shallow and fast, the high respiratory rate and wind velocity increase the airway resistance virtually, and also increase the resistance of the nebulized drug liquid to diffuse and distribute in the airway. For patients with chronic type II respiratory failure, simple non-invasive ventilator-assisted ventilation can alleviate the discomfort and fear of patients in the acute stage, avoid damage to important organs caused by chronic long-term hypoxia, and relieve hypercapnia. symptoms, and at the same time achieve the purpose of fully resting the tired respiratory muscles, but cannot achieve the effects of anti-inflammatory, expectorant, and asthma-relieving. Simple nebulization inhalation therapy and non-invasive ventilator-assisted therapy cannot take into account the patient's breathing and curative effect problems, and there is currently no effective medical device to solve this problem.

Compared with the prior art, the present invention has the following advantages:

1. The oxygen-driven atomization device of the present invention is used in combination with a non-invasive ventilator, while taking into account the patient's breathing and curative effect, to achieve the purpose of atomized inhalation of medicinal liquid for local administration, and the ventilator can support the treatment of the patient; The oxygen flow required to drive the nebulizer aggravates the patient's hypercapnia;

2. On the premise of not breaking away from the ventilator, the oxygen atomization driver is used to administer the liquid medicine through the respiratory tract, which achieves the effect of less liquid medicine and short atomization time, increases the settlement of aerosol particles in the lungs, and makes the particles rapidly It spreads to the lower respiratory tract, has a wide contact area with the airway, and has a direct effect and local application;

3. Due to the support of the pressure of the non-invasive ventilator, the patient's respiratory muscles are well supported, which relieves the fatigue of the respiratory muscles. At the same time, with the help of the wind speed of the non-invasive ventilator, the medicinal liquid reaches the deep bronchi, effectively exerting the drug. The curative effect relieves the bronchial spasm, and the dry rales are significantly reduced; due to the compensation of the ventilator, the patient's respiratory muscles have been fully rested, and they can effectively cough up sputum;

4. The combined application of the oxygen-driven atomization device of the present invention and the non-invasive ventilator increases the patient's compliance.
