Portable pneumology department dosing device

Abstract

The invention relates to the technicalfield of pneumology department dosing devices, and discloses a portable pneumology department dosing device. By adjusting the spiral-in depth and position of thelower end of the micro channel mechanism of a charging container, adjustment ofthe length of a capillary supply pipe extending into the lower channel isachieved,thusthe flow resistance of medicine liquid in the capillary supply pipe isadjusted, the adjustment of the atomization rate of different viscosity medicine liquid can be well achieved, better atomization effect is achieved, it is guaranteedthat the concentration of the medicine liquid in atomized airflow is in a better range, and the treatment effect is improved; the principle of venturi tube is adopted to achieve the atomization effect on the medicine liquid, stability and reliability are achieved, the service life is long, when an air pump sprays air flow to the contraction section at the lower end of a venturi tube assembly, thenegative pressure effect at anegative pressure cavity of the venturi tube assembly makes the medicine liquid enter the venturi tube assembly through the capillary supply pipe and the lower channel ofthe micro channel mechanism and form a mist shape, the effect of atomization treatment can be ensured, and the dosing effect and energy of breathing are improved.

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.
