Description

Disposable inhalation drug nebulizer

technical field

The invention relates to a novel disposable inhalation medicine nebulizer.

Background technique

Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases, and nebulization inhalation therapy uses the principle of gas jet to pass the drug solution through nebulizer and other atomization devices, and through the impact of water droplets, it becomes a fine mist Shaped particles, suspended in the gas, along with the patient's natural breathing, enter the respiratory tract and lungs through mouth and nose inhalation and deposit, so as to achieve the purpose of respiratory humidification or drug treatment. Its advantages are painless and rapid curative effect.

With atomized inhalation therapy, the smaller the sprayed aerosol particles of the liquid medicine, the more uniform the sprayed sprayed medicine liquid will be distributed on the mucosal surface, the better the dispersion effect, and the patient is easy to cooperate. The operation is simple, saves time, and also reduces the side effects of drugs.

Due to the simple structure of the existing liquid medicine atomizer, the atomization effect of spraying liquid medicine is greatly affected by the airflow generated during breathing. The liquid medicine particles are relatively large, which makes the recipient feel uncomfortable, accompanied by sensations such as pain and itching.

Contents of the invention

The technical problem to be solved by the present invention is how to overcome the above-mentioned defects of the prior art and provide a novel disposable inhalation medicine nebulizer.

In order to solve the above-mentioned technical problems, the novel disposable inhalation drug nebulizer includes a spray head and a base, wherein the spray head is sealed and connected to the base, and the inside of the base is provided with an atomizing core and a diversion nozzle, wherein the atomizing core is in the shape of Frustum-shaped, the upper end is provided with an atomizing beam, the diversion column extends into the atomizing core, and the inner wall of the end is tapered, and the spray head is equipped with a secondary atomization baffle, A spray head cover is arranged above the baffle.

With such a design, the atomizing core is designed in a conical shape, which fits more closely with the guide air column of the base to ensure that it is not easy to fall off when cleaning or adding liquid, and under the tapered channel, it instantly forms a trapezoidal vacuum, which will gradually increase with the air pressure. As the size increases, the power of the outlet also increases, driving the liquid medicine to be quickly broken up by the beam of the atomizing core, and hit the secondary atomization baffle, making the atomized particles more delicate while ensuring the atomization amount remains the same , so as to enhance the effect of treatment, so that the drug recipient can inhale the drug by breathing naturally, without pain and itching, and avoid discomfort to the drug recipient from causing resistance to the drug. After the diversion column extends into the atomizing core, the inner wall of the end is designed with a taper, which can reduce the loss of capacity, and ensure that when the low-pressure airflow passes through, the air pressure will gradually increase under the tapered channel, and a high-pressure vacuum will be formed instantly, especially in the When the central oxygen supply system of the hospital is under low pressure, usually when the air pressure is 2kg lower than normal, ensure that the nebulizer can also be used normally.

As an optimization, the middle part of the base is concave, and its cross-section is in the shape of ")(". This design makes it easy to hold.

As an optimization, several arc-shaped notches are provided on the lower edge of the base. Designed like this for easy placement.

As an optimization, the inner edge of the lower part of the spray head is provided with threads, and the outer edge of the upper part of the base is provided with a wire part matched with the threads, and the spray head and the base are screwed and connected through the thread and the thread parts. With such a design, the connection is firm and the airtightness is good.

As an optimization, the spray head is provided with a standard interface. This design makes it easy to adapt to general nebulizing masks.

The novel disposable inhalation medicine nebulizer has the advantages of simple structure, low cost, ingenious design and convenient use, and is suitable for hospital wards, household equipment and traveling.
