Pneumatic atomization dosing device

Abstract

The pneumatic atomization dosing device comprises an atomization end and a dosing end, an atomization tank is arranged at the atomization end, a first-stage nozzle is arranged at the bottom of the atomization tank, a first-stage air inlet is formed in the lower end of the first-stage nozzle, and a liquid spraying opening is formed in an outlet of the first-stage nozzle; a mist outlet is formed in the top of the tank body; an atomizing bottle and a liquid medicine bottle are arranged at the dosing end, and the liquid medicine bottle is connected with the liquid spraying opening of the tank body through a liquid medicine pipe; a second-stage nozzle is arranged at the bottom of the atomizing bottle, a second-stage air inlet is formed in the lower end of the second-stage nozzle, an atomizing opening is formed in an outlet of the second-stage nozzle and connected with the mist outlet of the tank body through an aerosol pipe, and a breathing opening is formed in the top of the atomizing bottle and connected with an oxygen mask; the first-stage air inlet is connected with a first-stage air inlet pipe, and the second-stage air inlet is connected with a second-stage air inlet pipe. The pneumatic atomization dosing device can reduce the influence of noise and is suitable for atomization treatment of children. In addition, medicine loss can be reduced, and medicine is saved.

Description

technical field [0001] The invention relates to a pneumatic atomization drug delivery device, which belongs to the technical field of atomization treatment equipment. Background technique [0002] Atomization inhalation therapy is to use an atomized device to disperse the drug into tiny droplets or particles, suspend it in the gas, and enter the respiratory tract and lungs to achieve the purpose of treating respiratory tract inflammation. Nebulization therapy is widely used in the treatment of children's respiratory diseases. In order to achieve the therapeutic effect, atomization treatment requires the droplets or particles to be refined to less than 10 microns. If the atomization effect is not good, it is difficult for the drug to enter the lungs with the gas. However, when used in children's treatment, the atomizing device is noisy, which can easily cause children's emotional anxiety and cannot maintain normal treatment. The noise of the atomizing device is generated by...

AI Technical Summary

Problems solved by technology

However, when it is used for the treatment of children, the noise of the atomizing device is loud, which can easily cause emotional anxiety in children and make it impossible to maintain normal treatment.

The noise of the atomization device is generated by high-pressure air flow. The higher the gas flow rate, the greater the noise, but the lower the gas flow rate, the better the atomization effect.

In addition, another problem with nebulization therapy is the large amount of drug loss. Only about 10% of the drug can be effectively deposited in the lungs. Most of the drug is discharged to the outside when exhaled, or deposited on the face, and it is easy to irritate the facial skin.
