AI Technical Summary
Existing nasal drug delivery equipment is mostly suitable for liquid drug preparations, and is not suitable for powder drugs. The liquid preparations are unstable and have high storage requirements, while the dry powder has good absorption effect but the equipment has poor sealing and is not convenient to fix on the head.
A nasal drug delivery device is designed, including a sealing assembly and a fixing assembly. The sealing assembly is threaded through the threaded connection of the A housing, the A threaded head and the B housing, combined with the rubber pad and the push rod piston system to achieve sealing and pushing out of the drug; the fixing assembly allows the device to be secured to the head through a combination of connecting rings, straps and Velcro.
The device protects the drug from contamination by strengthening its sealing properties, and reduces arm soreness or shaking caused by handheld devices by using fixed components, while filtering powder through a filter to prevent impurities from entering the nose.
