Abstract

The invention relates to a volume knob type dry powder storage and inhalation device. The device comprises a shell and a knob arranged at the top of the shell, the shell is internally provided with adrug measurement mechanism, a drug dropping mechanism and a drug inhalation mechanism which are arranged in sequence from top to bottom, and the knob is in transmission connection with the drug measurement mechanism. Compared with the prior art, the volumetric structure is adopted, and the device has a certain storage space for dry powder drugs, so that patients do not need to add drugs multiple times a day, and thus the time is saved; the counting function is provided, so that the patients can clearly know the residual amount of drugs in the device, the problem of wet oxidation of the drugs is avoided, the drugs can be stored for a long time, the troublesome operation of charging before each use of powdery drugs is avoided, and the problem that the dosage of each dosing is uncertain is avoided; the practicability is good, and convenience is brought to use. The device is simple in internal structure, small in overall volume, capable of carrying with patients conveniently and reducing the cost, and easy to put into production on a large scale.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a volume knob type dry powder storage and inhalation device. Background technique [0002] Pulmonary direct administration means that the powder drug directly reaches the lungs of the human body without passing through the digestive system of the human body. Due to the large absorption capacity of this technology and the absence of hepatic first-pass effect, its clinical application field has gradually developed from the traditional local treatment of asthma to the treatment of systemic diseases. Different from the general route of drug administration, pulmonary drug delivery requires the use of professional inhalation devices to complete the process of nebulization, dispersion and pulmonary delivery of drugs. A good inhalation device plays a non-negligible role in the process of pulmonary drug delivery. [0003] With the development of modern science and technology, powde...
