Description

A sliding multi-capsule dry powder inhalation device

technical field

The utility model relates to a sliding multi-capsule dry powder inhalation device.

Background technique

Since Charles Thiel's utility model inhaler in the mid-1950s, people have begun to use medical devices that deliver inhaled drug aerosols to patients in the treatment of asthma and chronic obstructive pulmonary disease.

Compared with oral administration and subcutaneous injection, inhalation administration has obvious advantages. Due to the large mucous membrane surface area of the human nasal cavity, bronchi and lungs, the human respiratory tract has a total of 23 bifurcations, and the adult alveolar surface area can be as high as 140 square meters. The alveolar wall is very thin and surrounded by a large number of capillaries. The drug particles can quickly pass through the alveolar mucosa tissue and directly enter the blood circulation. It has the advantages of no gastrointestinal degradation, no liver first-pass effect, small dose, quick onset, low toxicity and side effects, and is suitable for the delivery of biological macromolecules. Pulmonary inhalation drugs are the best treatment for lung diseases such as asthma and chronic obstructive pneumonia. In recent years, they have also been further expanded to treat systemic diseases, such as diabetes, with a huge market.

Existing inhalation devices include pressure metered dose inhaler (Pressurized Metered Dose Inhaler, pMDI), nebulizer (Nebulizer), dry powder inhaler (Dry Powder Inhaler, DPI) three forms. pMDI needs to use a propellant, although the environmentally friendly hydrofluoroalkanes that have no damaging effect on the atmospheric ozone layer are currently used as a propellant, it will still bring greenhouse effects; and when using pMDI, it is necessary to spray out the drug- Proper coordination of patient inhalation, otherwise inhalation efficiency is very low. Nebulizers are bulky, non-portable products generally suitable only for hospital or home use. DPI does not require a propellant; the drug dispersion is triggered by the patient's inspiratory airflow, and there is no synergistic effect; and the stability of biological macromolecules is higher in the dry powder state. Inhalation administration requires a high aerodynamic size of drug particles, and drug particles with an aerodynamic diameter of 0.5-5 microns can be effectively deposited in the lower respiratory tract and alveoli, thereby being effectively absorbed by the human body. Particles larger than 5 microns will be deposited in the mouth, throat and upper respiratory tract; while particles smaller than 0.5 microns, 90% will be exhaled with the patient's exhalation. However, the drug particle powder between 0.5-5 microns is usually easy to agglomerate, which requires formulation engineering technology and optimized design of inhalants to improve the dispersion of drug particles. An important parameter in evaluating the effectiveness of powdered medicaments during inhalation is the fine particle fraction (FineParticleFraction, FPF), which represents the proportion of the medicament ejected from the inhaler that has the opportunity to be deposited in the lungs. Typically, this fraction is defined as the fraction of particles in the medicament that have an aerodynamic diameter of less than 5 microns.

A dose of drug for inhalation is generally less than 50 micrograms, usually 25-50 micrograms. It is desirable that the doses drawn from the inhaler have a high degree of consistency, with the relative standard deviation (RSD) between doses not exceeding 5% for a predetermined dose of drug. Therefore, the existing method generally makes the medicine that needs to be inhaled into capsules.

Existing capsule dry powder inhalers are generally of single capsule type, which is inconvenient for users to use and replace once. However, several existing multi-capsule dry powder drug delivery inhalers also have relatively complicated structures and high production costs. It is relatively high, and it is difficult to inhale. At the same time, the existing multi-capsule dry powder inhaler also has poor moisture-proof effect. The method of use is complicated and it is inconvenient to fill capsules.

Therefore, the existing capsule dry powder inhaler needs to be further improved.
