Document Type and Number:
WIPO Patent Application WO/2024/061337
Kind Code:
A1
Abstract:
Provided is a nasal spray administration device, which is used together with an injection syringe. The nasal spray administration device comprises a nozzle and a syringe connector. A liquid collecting opening is formed in a distal end of the nozzle. The liquid collecting opening allows an interior and an exterior of the nozzle to be communicated. The syringe connector comprises a nozzle connecting part, and the nozzle is connected to the nozzle connecting part. A nozzle core is integrally formed at an end of a distal side of the nozzle connecting part of the syringe connector, and a flow channel is formed between an outer wall of the nozzle core and an inner wall of the nozzle. By means of the structure, the structure of the nasal spray administration device can be simplified easily, the molding precision of the nozzle core can be improved, and the relative position of the nozzle core and the rest part of the syringe connector is ensured to be fixed, so that the spraying effect is stabilized. The present invention further relates to a spraying system comprising the nasal spray administration device.
