A drug delivery device with double nostrils for the respiratory tract

Abstract

The invention relates to a drug inhaler and particularly relates to a respiratory tract dual-naris dosing device. An air inhaling and exhausting pipe (3) is respectively arranged on two pipe orifices of a T-branch pipe, the third pipe orifice of the T-branch pipe is provided with a connection pipe (6), the lower end of the connection pipe is connected with the inner wall of a fat pipe (10), the lower end of the connection pipe forms a sphere (8), the moving space of the sphere in the fat pipe on the upper portion of an inverted cone pipe (12) which is arranged at the lower end of the fat pipe, a slim pipe (13) is arranged at the lower end of the inverted cone pipe (12), an air inlet and outlet pipe (11) is arranged on one side of the fat pipe, the lower portion of the slim pipe is in inserted connection with the upper end of a drug inhaling pipe (14), and the sphere is located in the inverted cone pipe. According to the respiratory tract dual-naris dosing device, drug powders are distributed in two nares by using the T-branch pipe and the air inhaling and exhausting pipe, the drug powders synchronously enter focus parts in the two nares from the drug inhaling pipe, the fat pipe and the T-branch pipe when the sphere in the fat pipe and the inverted cone pipe controls inhaling drugs, and during expiration, the sphere closes the inverted cone pipe communicated with the drug inhaling pipe to achieve the purpose of saving the drug powders without affecting breathing.

Description

【Technical field】 [0001] The invention relates to a drug inhaler, in particular to a drug delivery device with double nostrils for the respiratory tract. 【Background technique】 [0002] As we all know, respiratory disease is one of the diseases that Chinese residents are exposed to more in their daily life.
