Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0019] Such as Figures 1 to 3 The counting mechanism of a dry powder inhalation device shown is characterized in that it includes a first counting disc 71, a second counting disc 72 is provided outside the first counting disc 71, and a second counting disc 72 is provided outside the second counting disc 72. There is a driven disk 73 that can drive the second counting disk 72 to rotate. On the outside of the first counting disk 71, the first counting disk 71 is provided with one rotation and the driven disk 73 is driven once to make the second counting disk 72 The toggle tooth 723 whose value is sequentially changed once, the first counting disc 71 is connected with the drive head 44 on the sliding support mechanism 4 in the dry powder inhalation drug delivery system. During the outward movement of the sliding support mechanism 4 , the d...

Abstract

The invention discloses a counting mechanism of a dry powder suction device. The counting mechanism comprises a first counting disc, the first counting disc is sleeved with a second counting disc, the outer side of the second counting disc is provided with a driven disc which can drive the second counting disc to rotate, the outer side of the first counting disc is provided with stirring teeth which stir the driven disc every time the first counting disc rotates so as to sequentially convert numerical values on the second counting disc one time. The first counting disc is connected with a driving head on a sliding bracket mechanism in a dry powder suction drug delivery system. The counting device overcomes defects in the prior art, and is simple in structure, convenient to install and capable of effectively recording the dry powder suction drug delivery system drug delivery frequency.

Description

technical field [0001] The invention relates to a counting mechanism of a dry powder inhalation device. Background technique [0002] Dry powder inhaler, which is a micronized aerosol without propellant, refers to micronized drugs or carriers in the form of capsules, blisters or multi-dose reservoirs, using a special dry powder inhalation device. Preparations that are actively inhaled by the patient. As a dosage form for pulmonary administration, dry powder inhalation is clinically used to treat local lung diseases such as asthma, chronic obstructive disease, and cystic fibrosis. [0003] Due to its large absorption area and no hepatic first-pass effect, the pulmonary drug delivery route has attracted extensive attention in the field of drug delivery system research and development, and its clinical application has also developed from traditional local treatment of asthma to systemic disease treatment. Different from the general route of drug administration, pulmonary drug...
