no. 1 approach

[0049] In the first embodiment, the dosing nozzle 11 and the dosing pump 12 in the dosing mechanism 1 and the suction head 21 and the circulation pump 22 in the circulation mechanism 2 are all fixed on the casing.

[0050] In this embodiment, the drug delivery nozzle 11 and the suction head 21 are set to be fixed relative to the housing 3, and the drug delivery nozzle 11 and the suction head 21 are arranged to be inserted into the drug delivery nozzle 11. When one nostril of the human body performs circular drug administration, the suction head 21 can be inserted into the other nostril for suction.

[0051] Specifically, such as Figure 1-Figure 3 As shown, the upper end of the housing 3 of the nasal circulation drug delivery device is provided with a first interface 31 and a second interface 32, and the lower end is provided with a first opening 33 and a second opening 34;

[0052] The drug delivery nozzle 11 is fixedly installed on the first interface 31, the drug delivery ...

no. 2 approach

[0064] In this second embodiment, refer to Figure 11 , the drug delivery pump 12 of the drug delivery mechanism 1 is installed in the housing 3, the drug delivery nozzle 11 is connected to one end of the second infusion pipeline 14 protruding from the outer side of the housing 3, Wherein the second infusion pipeline 14 is located at least part of the pipeline outside the housing 3 is flexible so that the drug delivery nozzle 11 can move relative to the housing 3; and / or,

[0065] The circulation pump 22 of the circulation mechanism 2 is installed in the housing 3, the suction head 21 is connected to one end of the first liquid return pipeline 23 outside the housing 3, wherein the At least a part of the first liquid return pipeline 23 outside the housing 3 is flexible so that the suction head 21 can move relative to the housing 3 .

[0066] The installation of the drug delivery pump 12 of the drug delivery mechanism 1 and the circulation pump 22 of the circulation mechanism 2...

Abstract

The invention provides a nasal cavity circulating drug delivery device. The nasal cavity circulating drug delivery device comprises a shell, a liquid storage tank, a drug delivery mechanism and a circulating mechanism, the interior of the liquid storage tank is divided into a stock solution storage cavity and a return liquid storage cavity, and a one-way valve is arranged between the stock solution storage cavity and the return liquid storage cavity; the dosing mechanism comprises a dosing spray head, a dosing pump, a first infusion pipeline and a second infusion pipeline, and liquid in the stock solution storage cavity is pumped to the dosing spray head by the dosing pump; the circulating mechanism comprises a suction head, a circulating pump, a first liquid return pipeline and a second liquid return pipeline, and liquid sucked by the suction head is pumped to the return liquid storage cavity by the circulating pump; a filter part is arranged in the return liquid storage cavity, and liquid sucked by the suction head is filtered by the filter part and then flows back to the stock solution storage cavity from the return liquid storage cavity through the one-way valve. According to the technical scheme provided by the invention, the effective staying time and the distribution space of the liquid medicine in the nasal cavity are improved through circular administration, medicine absorption is facilitated, and nasal cavity water inhaling and nasal cavity damage caused by water pressure are effectively prevented.
