Description

Ultrasonic atomization device for ventilator

technical field

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

Background technique

Atomization inhalation therapy refers to the use of a special atomization device to atomize the drug solution into tiny particles. The atomized drug particles enter the respiratory tract and lungs through inhalation and adhere to and disperse, producing a therapeutic effect locally in the lungs. Then the drug is absorbed by the human body to further play a role, so as to achieve the purpose of rapid, effective and non-invasive treatment. Among them, ICU patients often need atomization therapy for various reasons, especially for many patients with artificial airway for mechanical ventilation, because of asthma, thick sputum, and laryngeal edema, atomization is needed to help patients relieve the airway. Spasm relieves asthma, anti-inflammation reduces mucosal edema to prevent infection, thickens and dilutes sputum for easy removal, and unblocks the respiratory tract.

At present, the nebulizer fixed on the ventilator in the ICU ward mainly uses oxygen-driven atomization. On the one hand, the atomization efficiency of this method is not high, and on the other hand, the particle size of the atomized drug solution cannot be adjusted, so that the drug cannot be used. To achieve the best therapeutic effect, and most patients have 2~3 types of nebulized inhalation drugs, each drug has a different effect, the drug can only be added in stages, and the ventilator tube needs to be disconnected every time the drug is added The air leakage of the ventilator increases, and the tidal volume and minute ventilation are inaccurate, which leads to fluctuations in the patient's blood oxygen saturation and affects the therapeutic effect of the ventilator. In addition, there may be unattached liquid medicine particles in the exhaled gas of the patient. Due to the different media and pH of the medicine, the liquid medicine particles enter the ventilator along with the circuit, which may easily cause the filter membrane of the ventilator to be clogged, and even damage breathing. machine, shortening the service life of the ventilator.

Further, the liquid injection tube extends to the bottom of the liquid storage bottle, and the mouth of the liquid injection tube is provided with a sealing cap. This can ensure that when the liquid medicine is added, the end of the liquid injection tube remains in a liquid-sealed state, preventing oxygen from leaking from the liquid injection tube.

Further, a scale line is provided on the side of the liquid storage bottle.

Further, the hydrophobic filter membrane is detachably connected to the second air intake channel.

Further, both the liquid storage bottle and the water storage cup are transparent.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model uses ultrasonic waves to carry out adjustable atomization on the liquid medicine, especially for patients in the ICU, the therapeutic effect of the tiny particles of the medicine on the patient is better, so that the therapeutic effect of the medicine can reach the best, and the atomization efficiency is improved ;

2. The utility model is designed with a water collecting device, which prevents the non-attached medicine from returning to the ventilator in the exhaled gas of the patient, so as to avoid the damage of the medicine liquid to the ventilator;

3. The utility model has reasonable structure, convenient installation and disassembly, saves time and effort, can be used repeatedly, and has a long service life.
