Vibration mechanism of a dry powder inhalation device

technical field

The invention relates to a vibrating mechanism used for a quantitative feeding mechanism of a dry powder inhalation drug delivery system.

Background technique

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.

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 delivery requires a specific inhalation device to complete the dispersion, atomization and pulmonary delivery of the drug, and the inhalation device plays a key role in the pulmonary drug delivery system. At present, dry powder inhalation devices are mainly used as drug delivery devices. A dry powder inhalation device is a pulmonary drug delivery device that uses the patient's respiratory airflow or power device to aerosolize a certain amount of drug powder and deliver it to the lungs. Because of its simple use, easy portability, and good patient compliance, it is widely used in clinical practice.

detailed description

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

A vibrating mechanism of a dry powder inhalation device as shown in Figures 1 to 4 includes a vibrating plate 51, and the rear end of the vibrating plate 51 is provided with a button on the quantitative feeding mechanism 2 that can be moved when the vibrating plate 51 moves back and forth. The transmission plate 221 thus makes the quantitative feeding mechanism 2 vibrate the vibrating plectrum 53 for smooth blanking.

In the present invention, a clamping slot 52 is provided at the front end of the vibrating plate 51, and the vibrating plate 51 is clamped on the connecting boss 63 of the dustproof actuating cover 6 of the dry powder inhalation drug delivery system.

The quantitative feeding mechanism 2 in the present invention comprises a feeding seat 21, a material storage chamber 22 is provided on the upper end surface of the material supply seat 21, and a lower end that runs through the material supply seat 21 longitudinally is provided at the lower end of the storage room 22. The feed port 23 is provided with a discharge pipe 24 on the feed seat 21, and the rear end opening of the discharge pipe 24 runs through the feed seat 21 longitudinally, and a mounting is provided on the lower end surface of the feed seat 21. Groove 28, described feed opening 23 and discharge pipe 24 rear ends are respectively connected with installation groove 28, and in described installation groove 28, the quantitative chamber mechanism 25 that can quantitatively feed material to discharge pipe 24 is provided with, and described The transmission piece 221 is arranged on the left and right sides of the storage chamber 22 .

Quantitative chamber mechanism 25 described in the present invention comprises the quantitative chamber seat 251 that can slide, is provided with quantitative groove 252 on quantitative chamber seat 251, is provided with positioning groove 253 in described quantitative chamber seat 251 lower end surface, in described The positioning groove 253 is provided with a shrapnel 254 that can make the quantitative chamber seat 251 press against the lower end surface of the material supply seat 21 .

In the present invention, the quantitative chamber mechanism 25 is connected to the sliding support mechanism 4, the dust-proof actuation cover 6 is connected to the sliding support mechanism 4, and the vibration plate 51 is arranged on the dust-proof actuation cover 6 and the sliding support mechanism. between 4.

In the present invention, the sliding bracket mechanism 4 includes a sliding bracket 41, on which the accommodating groove 42 for installing the quantitative chamber 25 of the quantitative feeding mechanism 2 is provided on the sliding bracket 41, and on both sides of the sliding bracket 41 Connecting bracket arms 43 are respectively arranged on the top, and a driving head 44 capable of driving the counting mechanism 7 is arranged on one of the connecting bracket arms 43 , and a waist-shaped connecting hole 45 is provided in the connecting bracket arms 43 . A dust-proof actuating cover 6 is plugged into the waist-shaped connecting hole 45 .

During the use of the present invention, the dust-proof actuating cover 6 is pulled out from the housing 1 by hand, and the dust-proof actuating cover 6 drives the vibration mechanism 5 to move outward during the pulling-out process.
