Drug delivery device for respiratory medicine department

Abstract

The invention relates to the technical field of medical instruments, in particular to a drug delivery device for the respiratory medicine department. The drug delivery device comprises a first drug storage tank, a connecting pipe is arranged on the first drug storage tank, and a handle and a drug inlet side door are arranged on the side wall of the first drug storage tank; the outer side of the first drug storage tank is provided with an inflator pump, the inflator pump is communicated with the first drug storage tank through an air inflation pipe, and a first disc, a second disc and a spray pipe are arranged in the first drug storage tank; a first through hole is formed in the second disc, a cover body is arranged at the end of the connecting pipe in a sleeving mode, and a bottom cover isarranged at the bottom of the first drug storage tank; a second through hole is formed in the bottom cover, the side wall of the second through hole is provided with a groove and a column-shaped hole, and a baffle is arranged in the second through hole; the side wall of the baffle is provided with an inserting block matched with the groove, and a column body matched with the column-shaped hole isfurther arranged on the side wall of the baffle; a second drug storage tank is arranged below the first drug storage tank. The technical scheme can overcome the defects that an existing drug deliverydevice for the respiratory medicine department is not uniform in drug delivery, and the drug storage amount is not easy to adjust to a certain degree.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug delivery device for respiratory medicine. Background technique [0002] Respiratory diseases include acute and chronic inflammation of the upper and lower respiratory tracts, respiratory allergic diseases, pleural diseases, foreign bodies in the respiratory tract, congenital malformations and lung tumors. Among them, acute respiratory infection is the most common, accounting for more than 60% of pediatric outpatient clinics, and the rate is higher in northern regions. Oral drug therapy, nebulization therapy, and drug spray therapy are commonly used clinically. The applicators for respiratory medicine provided by the prior art usually have the defects of uneven drug delivery and difficult adjustment of drug storage volume.
