Abstract

The invention discloses a medicine delivery apparatus and medicine delivery method for an olfactory cleft region. The medicine delivery apparatus for the olfactory cleft region is characterized in that a pressurizing device is movably connected with a sprayer; the sprayer comprises an end cap portion, and one end of the end cap portion is connected with the pressurizing device while the other endof the end cap portion is connected with one end of a medicine storage chamber; the other end of the medicine storage chamber is connected with a soft nozzle. According to the technical scheme, the medicine storage chamber in the sprayer is separated from the pressurizing device and arranged at a position closest to the soft nozzle to enable medicines to be thoroughly delivered into the nasal cavity; further, repeated medicine adding can be performed by opening the end cap portion of the medicine storage chamber; in addition, the soft nozzle is arbitrarily changeable in shape and beneficial toextension into the nasal cavity (such as nasal vestibule) to realize medicine delivery in the olfactory cleft region.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of medical equipment, in particular to an olfactory cleft area applicator and drug delivery. Background technique [0002] Nasal diseases are relatively common diseases, and patients usually need to take medicine in the patient, or spray medicine into the nasal cavity for treatment. [0003] Due to the unreasonable design of the spray port or the unreasonable setting of the drug delivery device, the existing spraying device cannot break through the barrier of the nasal threshold, and the drug cannot be accurately sprayed to the designated position inside the nasal cavity. Especially for those who need to spray medicine into the deep part of the nasal cavity, such as the olfactory cleft area, the existing drug dispenser cannot meet the needs of users for spraying medicine. Contents of the invention [0004] The drug delivery device for the olfactory cleft area and the drug deliver...
