A portable sprayer for ENT care

Abstract

The invention discloses a portable medicine sprayer for ear, nose and throat care, which comprises a stirring tank, a medicine delivery pipe and a medicine storage pipe. A threaded rod penetrating through the side wall of the medicine storage pipe is horizontally arranged at the middle position on one side of the push plate. A connecting pipe is installed on the side of the drug storage tube away from the threaded rod, and a liquid blocking ball is arranged in the middle of the connecting tube, and a sleeve is installed on the side of the connecting tube away from the drug storage tube horizontally. A drug delivery tube is arranged horizontally inside the drug storage tube, a stirring tank is installed on the side close to the connecting pipe at the top of the drug storage tube, and an adding port is arranged on the side close to the connecting pipe at the top of the stirring tank. In the present invention, by setting the liquid blocking ball inside the connecting pipe, when the liquid medicine flows too fast, the liquid blocking ball will be pushed to move toward the casing, so that the gap between the connecting pipe and the drug delivery tube becomes smaller, and the flow speed of the liquid medicine is slowed down. Prevent the speed of liquid medicine flow from accelerating, causing discomfort to the patient when spraying medicine.
