A portable respiratory drug delivery device

Abstract

The invention relates to the technical field of respiratory drug delivery devices, and discloses a portable respiratory drug delivery device. The invention realizes the extension of the capillary supply tube into the lower end flow channel by adjusting the depth and position of the lower end of the screw-in micro-channel mechanism of the drug-charging container. The adjustment of the length of the channel, and then adjust the flow resistance of the liquid medicine in the capillary supply tube, can well realize the adjustment of the atomization rate of the liquid medicine with different viscosities, achieve a better atomization effect, and ensure the atomization airflow The concentration of the traditional Chinese medicine liquid is in a better range to improve the therapeutic effect; the invention adopts the principle of the Venturi tube to realize the atomization of the medicinal liquid, which is stable and reliable, and has a long service life. When the air flow is sprayed, the negative pressure at the negative pressure chamber of the Venturi tube assembly makes the liquid medicine enter into the Venturi tube assembly through the capillary supply tube and the lower end channel of the micro-channel mechanism and form a mist, which can ensure the atomization treatment. Effect, improve respiratory drug delivery and energy.

Description

technical field [0001] The invention relates to the technical field of respiratory drug delivery devices, in particular to a portable respiratory drug delivery device. Background technique [0002] The general way to treat respiratory diseases is injection or oral medicine, but neither of these two methods can effectively treat patients with deep respiratory tract directly. In order to improve the treatment effect of patients, it is necessary to directly deliver medicine to the respiratory tract to achieve rapid treatment effect. . However, at present, the respiratory drug delivery device in the hospital generally installs the breathing mask on a special atomization device. This structure is relatively large, and it needs to go to the hospital for atomization every time. Atomization, however, due to the lack of power of the general atomizer, it is easy to have the problem of too fast or too slow atomization when using it, especially for liquid medicines with high viscosity ...

[0002] The general way to treat respiratory diseases is injection or oral medicine, but neither of these two methods can effectively treat patients with deep respiratory tract directly. In order to improve the treatment effect of patients, it is necessary to directly deliver medicine to the respiratory tract to achieve rapid treatment effect.

However, at present, the respiratory drug delivery device in the hospital generally installs the breathing mask on a special atomization device. This structure is relatively large, and it needs to go to the hospital for atomization every time. Atomization, however, due to the lack of power of the general atomizer, it is easy to have the problem of too fast or too slow atomization when using it, especially for liquid medicines with high viscosity or low viscosity. As a result, the concentration of the drug solution in the atomized airflow is either too high or too low, which affects the drug delivery effect.
