Problems solved by technology

For this kind of powder administration, many of them on the market are administered through hand-squeezed medicine bottles. The problem with this administration method is that firstly, the dosage cannot be controlled, and the powder cannot be dried at the same time, and the sealing effect is not good. Well, and there is no way to know exactly how much medicine is left in the bottle in case you need to buy a new one
Therefore, there are many factors affecting the successful drug administration, so the reliability is low

Description

technical field [0001] The invention relates to a medical product, in particular to a powder quantitative drug delivery device. Background technique [0002] Powder medicine refers to one or more medicines, which enter the respiratory tract in the form of dry powder or spray on the wound through a special drug delivery device. Powder is based on aerosol. A new dosage form developed based on the knowledge of body engineering. It is easy to use, does not contain propellant, the drug is in powder form, has good stability, less interference factors, and has the characteristics of targeting, quick effect, and small toxic and side effects. Therefore, it has been paid more and more attention by people. At present, powders also occupy quite a lot of pharmaceutical dosage forms on the market, such as: watermelon cream powder, Yunnan Baiyao powder, etc. For this kind of powder administration, many of them on the market are administered through hand-squeezed medicine bottles. The pr...
