Description

A partition type compressed air atomizer

technical field

The utility model relates to an atomizer, in particular to a cut-off air compression atomizer.

Background technique

Medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli, and chest cavity. Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lung deposition through inhalation, so as to achieve painless , The purpose of rapid and effective treatment. At present, the most widely used is the air compression atomizer, also called jet atomization, which is based on the principle of Venturi (Venturi) injection, using compressed air to form a high-speed airflow through a small nozzle, and the negative pressure generated drives liquid or other fluids. They are sprayed onto the barrier together, and splash around under the high-speed impact to make the liquid droplets become mist particles and spray out from the outlet pipe.

The existing air-compressed nebulizer includes a medicine cup, an atomizing device set in the medicine cup and a mask (or mouthpiece), and is connected with an air pressure device or an ultrasonic device through a catheter. Since the V-shaped funnel in the medicine cup is not strictly separated or divided into chambers, after different liquid medicines are poured into the same medicine cup, all the atomized liquids are mixed together passively. Due to the variety of combined medicines, some medicines may be passively mixed together. There are incompatibility after mixing. For example, drug administration to the respiratory tract often involves combined drugs (phlegm-reducing drugs and anti-asthma drugs, or hormone drugs in anti-asthma drugs combined with β-receptor agonists, etc.), such combined drugs directly When it is put into the existing air-compressed nebulizer medicine cup to mix and atomize together, the problem of in vitro failure often occurs, such as neutralization and hydrolysis reactions before the medicine liquid enters the human body, thereby reducing the risk of the medicine liquid entering the human body. The curative effect that can be achieved after absorption in the body, in severe cases, solid particles will be inhaled by the patient and cause serious consequences; but if sequential nebulization is used, each of the medicinal liquids with incompatibility is put into the nebulizer separately. Atomization, after the atomization is completed, the second medicinal liquid is put in until the last medicinal liquid is atomized. This method will increase the workload of medical staff, increase the cost of treatment, and delay the treatment time.

Utility model content

The purpose of the invention of the utility model is to provide a partitioned compressed air atomizer to address the disadvantages of the existing compressed air atomizer, which are not suitable for the atomization of combined medicines with incompatibility because the medicine cup is not cut off.

The baffle can divide the funnel into several independent units with openings, and each partitioned independent unit of the funnel can be filled with different liquid medicines, and then select the matching atomizing device and connect it to the air source tube. The nebulizer can work; the nebulizer can avoid the problem of in vitro failure after the incompatible medicinal liquid is mixed in the solution state, and at the same time save the treatment time and reduce the medical cost.

Preferably, the several baffles are evenly distributed in the funnel.

Preferably, the plurality of baffles includes four baffles.

Preferably, the baffle is integrally formed with the funnel, the tapered tube, and the medicine cup, which is convenient for processing and more reliable in structure.

Divider rib holes, the conical tube is provided with several slots along the busbar, the number of the slots is equal to the number of the baffle plate, the conical tube is adapted to the conical tube, and the slots can Fits the baffle.

When the groove on the conical tube is aligned with the baffle, the conical tube can be smoothly adapted to the conical tube of the funnel device. When the atomizer is working, the high-speed airflow passes through the air outlet of the conical tube, and the negative pressure generated The liquid in each partition is driven to flow out along the gap between the conical tube and the conical tube, and the high-speed airflow drives the liquid to spray on the two wings, forming mist-like particles under high-speed impact.

To sum up, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the partition type compressed air atomizer described in the utility model uses a baffle to partition the funnel, the partition parts are not connected to each other, and the partition can Different medicinal liquids with incompatibility are put into different funnel partitions respectively. When the compressed air reaches the atomization device, the compressed air flow can impact the medicinal liquid in each funnel partition into aerosol, which can be used by patients, thus avoiding the Some medicines with contraindications have the problem of failure in vitro after being mixed in the solution state; compared with using traditional nebulizers for sequential atomization, different medicines can be atomized at the same time at one time, which saves time. Reduced medical costs, easy to use.
