Abstract

A spraying drug delivery device comprises a sleeve, wherein an internal cavity is formed in the sleeve and can accommodate a needle cylinder of a syringe; and at least one spray nozzle, wherein the spray nozzles are arranged at the front end of the sleeve and communicate with the internal cavity of the sleeve. An axial direction of each spray nozzle forms an angle with an axial direction of the sleeve. A finger-pressure pinch plate may also be formed at or adjacent to the rear end of the sleeve. Two spray nozzles can also be arranged at the front end of the sleeve. The spraying drug delivery device can achieve full spraying of medicated liquid, uniform drug delivery and leakage prevention. The invention further relates to a spraying drug delivery system comprising the device.

Description

technical field [0001] The present application relates to a drug delivery device, especially a drug delivery device that can be used in conjunction with a syringe and deliver medicine to a human body in the form of a spray. Background technique [0002] Syringes are commonly used medical devices in the medical field, and are used to inject drugs into the human body for disease treatment, vaccine implantation and other operations. At present, there is a spray drug delivery device used in conjunction with a syringe on the market. After the liquid medicine is sucked into the syringe, the spray drug delivery device can be fitted to the syringe, and then the nozzle of the spray drug delivery device is aimed at the nasal cavity and oral cavity. Or other parts of the human body suitable for drug administration, by pushing the syringe, the drug solution is atomized and delivered to the human body. Compared with traditional syringe drug delivery, this spray drug delivery device can ...
