Inhaler, Respiratory Tract and Lung Model Device Integration for Sorting Flower-Shaped Particle Carriers

Abstract

The present invention provides an equipment integration of an inhaler for sorting flower-shaped particulate carriers, a respiratory tract and a lung model. The equipment integration mainly comprises an inhaler, respiratory tract model equipment, a respiratory segment curve particulate collector, lung model equipment, a lung model right curve particulate collector, a lung model left curve particulate collector, and a sucking pump. According to the technical scheme of the invention, the somatological equipment is creatively adopted and integrated with curve particulate collectors in accordance with the aerodynamics. Therefore, the capability of traditional equipment in separating particulates of different sizes is broken through. On the basis that particulates of different sizes can be sorted, flower shapes and particulates of other shapes can also be sorted. The equipment integration is particularly used for the separation of flower-shaped particulate carriers of dry powder inhalers in mixed particulates. The preparation process of medicine carriers is improved, and the practicability is higher.

Description

technical field [0001] The invention relates to a particle sorter, in particular to an inhaler for sorting flower-shaped particle carriers, respiratory tract and lung model equipment integration. Background technique [0002] The dry powder inhaler carrier is a tool for carrying drug molecules deep into the lungs. Based on the lung trachea structure and physical and chemical properties, the optimal size of the carrier is 1-5 microns, and the flower-shaped or rough spherical shape is preferred. Due to the limited precision of micro- and nano-preparation techniques, the particle carrier produced by crystallization, grinding or other methods often has a normal distribution in shape and size, and the produced particle carrier needs to be sorted. [0003] The prior art records a kind of "particle separator" (application number CN02815701.X), which uses electric field separation equipment to separate the dotted particles in the air.

Problems solved by technology

[0003] The prior art records a "particle separator" (application number CN02815701.X), which uses electric field separation equipment to separate the dotted particles in the air. (such as lactose), which are neutral and cannot be separated in an electric field

[0004] The prior art records a kind of "air flow particle sorter and fluidized bed reactor and its application" (application number CN201210420999.6), by changing the guide air outlet, according to the difference in the inertia of particles of different sizes, the particles are sorted out by wind force Large and small particles are better for size separation, but this method cannot separate particles with different shapes

[0005] The prior art records a "Jet Suction Particulate Material Wind Separator" (application number CN201010590628.3), which uses a tapered tube-type sorting pipeline to generate negative pressure to separate heavier particles from the airflow It is better for size separation, but it is also difficult to sort particles with different shapes.
