Description

technical field [0001] The invention relates to the technical field of respiratory treatment devices, in particular to a clinical inhalation drug delivery device for respiratory medicine. Background technique [0002] With the progress of society, almost everyone has a car at home, but when a large number of cars flood the streets, the exhaust gas will also cause great pollution to the air, which will cause many people to have respiratory diseases. The medicine used when treating the respiratory tract often needs to be directly sprayed in the patient's respiratory tract, so that the patient can inhale in the respiratory tract by himself, so a special respiratory tract drug delivery device is needed. [0003] Patent CN201220165435.8 discloses a simple drug delivery device for the respiratory tract. This device is aimed at the current technology of administering medication to the respiratory tract or nasal cavity by directly dripping or spraying the drug into the nasal cavity ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned drug delivery device has some shortcomings: 1. The above-mentioned drug delivery device is not convenient to store the medicine in the device first, and then administer the drug. The tube is the same as the external drug delivery device for direct drug delivery, which is inconvenient to control the speed of drug delivery, and it is easy for the patient to choke during the drug delivery process, causing discomfort and reducing the practicability of the drug delivery device

2. The above-mentioned drug delivery device can only give one kind of drug alone, and it is not convenient to administer different kinds of drugs to the patient at the same time. If different drugs need to be given, the above-mentioned drug delivery device needs to be taken out from the patient's respiratory tract and then inserted into the patient's respiratory tract internally, causing repeated patient discomfort and reducing the practicality of the drug delivery device
