Abstract

The embodiment of the invention provides a spraying device. The spraying device comprises a device shell, a capsule detachably installed on the device shell and a control module arranged in the device shell. The device shell comprises an outer cavity suitable for containing the capsule. The control module comprises a control joint at least partially exposed to the outer cavity; the capsule comprises a capsule shell suitable for containing a reagent, an ultrasonic atomization sheet arranged in the capsule shell, and an atomization sheet connector which is connected with the ultrasonic atomization sheet and is at least partially exposed out of the capsule shell; the atomizing sheet joint is suitable for being at least partially exposed in the outer cavity and is in contact connection with the control joint when the capsule is accommodated in the outer cavity; the control module is suitable for controlling the ultrasonic atomization sheet to work when the control connector is in contact connection with the atomization sheet connector so that the reagent can be sprayed out in a mist spraying mode after being atomized. The spraying device does not need to invade into the nasal cavity and can be repeatedly used.

Description

technical field [0001] The invention relates to a spray device. 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 to exert therapeutic effects while playing a barrier role. Traditional drug delivery methods, such as transcranial in situ injection and subarachnoid injection, 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 avoid the blood-brain barrier and enter the brain through the nasal cavity. At present, the existing nasal cavity drug delivery technology has been widely used. However, the existing nasal drug delivery devices ...
