Description

A pen-type nebulizer that can be used for nebulized inhalation

technical field

The utility model relates to a pen-type atomizer, in particular to a pen-type liquid-separating atomizer suitable for vaccine atomization.

Background technique

Nowadays, with the air pollution becoming more and more serious, coupled with the sudden cold and warm weather during the season transition, the number of patients with respiratory diseases has greatly increased. Nebulized inhalation administration can greatly slow down respiratory problems. The existing atomized drug delivery devices in the prior art mainly use the method of atomizing and inhaling to administer drugs, and it is necessary to instruct the subjects before administering the drug. Children and even many adults often suffer from inhalation and self-breathing. Improper frequency control greatly affects the inhalation and absorption of drug mist, which is very unfavorable for immunization or disease treatment. In addition, there may be a risk of cross-infection when inhaling while misting. The utility model relates to a pen-type atomizer, which can atomize medicinal liquid into a cup in advance and then inhale it into the body, which can prevent cross-infection, reduce cost, and have high inhalation and inoculation efficiency. At present, a treatment method for respiratory diseases is nebulized inhalation administration, which uses a nebulizer to disperse the liquid medicine into fine mist droplets, which are inhaled through the patient's nose or mouth, and the nebulized medicine directly acts on the target organ, which can Increase the local concentration of the drug to achieve the therapeutic effect. Nebulized inhalation has a very good therapeutic effect on bronchiolitis, asthmatic bronchitis, bronchial asthma, acute and chronic bronchitis, acute laryngitis, and acute pneumonia.

Atomized inhalation vaccine is a vaccine that is immunized by atomization inhalation. The so-called aerosol inhalation immunization means that the vaccine is atomized into tiny particles through a nebulizer, and these tiny particles enter the respiratory tract and lungs by breathing inhalation, stimulating mucous membranes. immunity.

The equipment and devices that realize this nebulized inhalation treatment and immunization are very important for the implementation and quality of treatment and immunization, and have received great attention from researchers. The existing atomized drug delivery devices in the prior art mainly use the method of atomizing and inhaling to administer drugs, and it is necessary to instruct the subjects before administering the drug. Children and even many adults often suffer from inhalation and self-breathing. Improper frequency control greatly affects the inhalation and absorption of drug mist, which is very unfavorable for immunization. In addition, for immunization, to prevent cross-infection, the part of the device that is inhaled by the subject should be disinfected or discarded after use. In view of the necessity of large-scale vaccination, it is an urgent problem to provide an atomized drug delivery device that can prevent cross-infection while reducing costs and has high inhalation vaccination efficiency.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a pen-type nebulizer, which can be used to generate medicine mist for inhalation by subjects to achieve therapeutic or immune effects.

Vaccinators do not need injections, but only need to inhale the vaccine into the respiratory tract and lungs through a pen nebulizer, so as to obtain the "triple protection" of mucosal immunity, cellular immunity and humoral immunity. Compared with the cellular immunity and humoral immunity formed by the injectable new crown vaccine, the vaccine for aerosol inhalation can induce mucosal immunity in the human body, preventing infection and blocking transmission at the first point of virus invasion.

Utilizing the atomizing pen of the utility model, the vaccine for atomizing inhalation can be inoculated with just one inhalation, which is safer and more convenient, and is suitable for popularization and use by large-scale crowds. At the same time, a dose of vaccine for aerosol inhalation only needs one-fifth of the dose of intramuscular injection, and the level of cellular immune response produced is equivalent to that of intramuscular injection, which means that the production capacity is indirectly increased by five times.

The purpose of the utility model is to solve the problems of cross-infection, high cost and low efficiency in the existing atomization device while misting and sucking. A pen-type nebulizer is provided. When medication is required, the medicinal solution can be atomized into the cup in advance and then inhaled into the body to achieve the purpose of treatment or immunization.
