Description

Technical Field

[0001] The utility model relates to the technical field of nasal medication devices, in particular to a nasal therapeutic medication device. Background Art

[0002] The nose is the organ used by the human body for breathing. Since the air contains various microorganisms, the nose is easily infected with viruses during the process of breathing air, which can cause some nasal diseases. At this time, a nasal drug delivery device is needed for treatment.

[0003] After searching, the patent publication number CN212038575U discloses a nasal sustained-release drug delivery device, which solves the shortcomings of the prior art, such as the inconvenience of nasal sustained-release drug delivery and the complicated loading and changing of materials. It includes a nasal tube, the bottom of which is connected to a guide tube, and the end of the guide tube is provided with a nozzle through an intermediate plate, a material changing slot is provided on the nasal tube, and a sealing plate is hinged on one side of the material changing slot, a mother buckle is installed on the sealing plate, and a child buckle is provided on the other side of the material changing slot, a function plate is provided on the inner wall of the nasal tube, and a support spring is fixedly connected to the lower surface of the function plate. The utility model uses a nozzle with an isolation and disinfection sheath to perform sustained-release drug delivery to the nasal cavity, and the isolation protection is safe and reliable. The drug delivery is performed by pressing the linkage handle to resist the elastic force of the support spring and press the pressing plate downward, and the material changing and loading work is convenient, and the nasal drug delivery work can be performed sustainably.

[0004] However, this patent still has some shortcomings. This patent does not have a structure that can limit the nozzle. The stability of the nozzle after being inserted into the nasal cavity is poor. The nozzle is easy to fall out of the nasal cavity during operation, thus affecting the normal drug administration. There is no sealing structure between the nasal tube and the guide tube. After adding the medicine, part of the medicine is easy to flow out directly from the guide tube, resulting in waste of medicine.

[0005] To this end, we propose a nasal therapeutic drug delivery device. Utility Model Content
