Abstract

The present invention provides a spray device, which includes a capsule and a base suitable for installing the capsule; the capsule includes a nozzle, a first reagent cavity suitable for accommodating reagents, and a second reagent communicated with the first reagent cavity and the nozzle respectively. a cavity, and a first piston assembly located in the second reagent cavity; the base includes a connecting assembly adapted to magnetically connect the first piston assembly, a gas cavity in communication with the connecting assembly, and a second at least partially located in the gas cavity a piston assembly; the first piston assembly includes a first air passage; the connecting assembly includes a second air passage respectively communicating with the first air passage and the gas cavity; at least one of the first air passage and the second air passage is provided with a pressure valve; The second piston assembly is adapted to be pressed to compress the gas in the gas chamber and push the first piston assembly to move in a direction away from the connecting assembly; and further push the reagent in the second reagent chamber to move, so that the reagent flows from the second reagent chamber The body is ejected along the nozzle for deep non-invasive drug delivery.

Description

technical field [0001] The present invention relates to the technical field of spray devices. Background technique [0002] The blood-brain barrier is a natural barrier between the systemic circulation and the central nervous system. However, it also prevents many drugs from entering the central nervous system for therapeutic effects. Traditional drug delivery methods, such as transcranial in situ injection, subarachnoid injection, etc., are difficult to be widely used in clinical patients due to strong trauma and high technical requirements. [0003] A large number of clinical studies have found that the olfactory area of ​​the nasal cavity is a location where nerve cells are in direct contact with the surrounding environment, which makes it possible for drugs to escape the blood-brain barrier and enter the brain through the nasal cavity. At present, the existing nasal administration technology has been widely used. However, the existing nasal drug delivery devices either...
