A medicine delivery device for a nasal cavity

Abstract

A medicine delivery device for a nasal cavity comprises a medicine storage bottle body (2), a pump (3) arranged on the medicine storage bottle body (2) and a push button (4), wherein the bottom of theliquid storage cavity of the medicine storage bottle body (2) is a conical cavity or a conical mesa cavity, and the lower end of the liquid suction pipe head (6) located in the middle of the liquid storage cavity of the medicine storage bottle body (2) is adapted to the bottom of the liquid storage cavity of the medicine storage bottle body (2) for fully sucking the medicine liquid; the medicinestorage bottle body (2) is provided with a shell (1) capable of partially or completely wrapping the medicine storage bottle body (2), and the shell (1) and the medicine storage bottle body (2) are kept in a connected state when the shell (1) is opened to expose the medicine feeding part of the medicine storage bottle body (2). The liquid suction pipe head in the nasal cavity medicine delivery device of the invention can sufficiently absorb the medicinal liquid in the liquid storage chamber; and a housing is always connected with the medicine storage bottle body, and a child safety device is arranged on the housing to prevent contamination and avoid the waste of the medicine liquid caused by misoperation.

Description

technical field [0001] The invention relates to a packaging drug delivery structure for nasal cavity diseases, in particular to a nasal drug delivery device that can make full use of the drug solution and avoid pollution caused by detachment of the dust-proof cover. Background technique [0002] During the treatment of nasal cavity diseases, it is often necessary to spray some drugs into the nostrils, and some diseases need to be prevented by administration of nasal mucosa. Therefore need to design some nasal administration devices to accomplish this purpose. At present, most of the existing nasal spray device bottle designs on the market are cylindrical or molded flat bottles with a relatively large bottom area, which makes the suction tube unable to fully absorb the medicinal liquid at the bottom of the liquid storage bottle. Overfill to ensure correct dosing at the indicated number of doses. In addition, for the sake of sanitation, dust-proof covers will be installed, b...

AI Technical Summary

Problems solved by technology

At present, most of the existing nasal spray device bottle designs on the market are cylindrical or molded flat bottles with a relatively large bottom area, which makes the suction tube unable to fully absorb the medicinal liquid at the bottom of the liquid storage bottle. Overfill to ensure correct dosing at the indicated number of doses

In addition, for the sake of sanitation, a dust cover will be installed, but the existing dust cover can be easily opened or dropped, resulting in contamination of the nozzle and loss of liquid medicine

Another disadvantage of the existing dust cover is that it is separated from the bottle body, and it is easy to drop and lose when carrying it out, causing pollution

Most of the nozzle dust cover of the nasal spray device can be easily opened, and children can imitate the actions of adults to open the dust cover, resulting in pollution of the nasal spray nozzle and waste of liquid medicine, and even accidental ingestion
