Description

A targeted drug-based dosing device TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a targeted drug-based dosing device. BACKGROUND

[0002] The blood-brain barrier is a natural barrier between the systemic circulation and the central nervous system, which plays a barrier role to block pathogenic microorganisms and harmful substances from entering the brain. At the same time, it also hinders many drugs from entering the central nervous system through blood circulation to play a therapeutic role. Many current drug delivery methods, such as intracranial injection in situ, subarachnoid injection, and the like, and the current nasal drug delivery device are increasingly mature in terms of drug dispersion, transmission and distribution. From simple nasal cavity cleaning sprayer, nasal spray, to the application of ultrasonic atomization and osmotic pump in the nasal drug delivery device.

[0003] In the prior art, a targeted drug-based dosing device is disclosed in Chinese Patent No. CN219440377U. By setting a medicine storage barrel, a moving plate and a rubber cylinder, one end of the rubber cylinder is inserted into the nasal cavity, the push rod is pushed, the moving plate can move inside the medicine storage cylinder, so that the targeted drug inside the medicine storage cylinder is pushed out through the dosing channel, and at the same time, the moving plate extracts air at the bottom of the medicine storage cylinder, so that the refluxed drug in the nasal cavity enters the inside of the main body through the first recovery channel. The problem that the current drug delivery device does not have a reflux prevention part, directly communicates with the outside world, increases the possibility of drug contamination and deterioration, reduces the effective period of use of the drug, and the drug reflux easily leaks out, resulting in inaccurate drug delivery amount is solved.

[0004] However, the above-mentioned device still has the following problems in the implementation process: when the patient's nasal cavity is dosed, the sealing piston needs to be manually pushed to move, and the single injection amount is manually adjusted by observing the shell scale, which requires higher operation experience of medical personnel. In home nursing, nursing staff cannot master the injection amount of the drug in a short time, and single injection of too much drug often occurs, which not only causes waste of the drug, but also is not conducive to the recovery of the patient.

[0005] Therefore, we provide a targeted drug-based dosing device to solve the above-mentioned problems.
