Description

Technical Field

[0001] The present invention relates to the technical field of nasal sprayers, and in particular to a physiological saline nasal sprayer capable of improving the utilization rate of liquid medicine. Background Art

[0002] As a common medical device, saline nasal sprayer is widely used to relieve nasal dryness, clean the nasal cavity and assist in the treatment of respiratory diseases such as allergic rhinitis and colds. It atomizes saline and sprays it onto the nasal mucosa to moisturize, reduce inflammation and promote the discharge of secretions.

[0003] Currently, a Chinese invention with publication number CN106110453B discloses a saline nasal sprayer, comprising a main bottle, a pump, and a bottle cap. The pump is mounted on the main bottle and is used to extract liquid from the bottle. The bottle cap snaps into place with the main bottle to form a sealed receiving chamber, in which the pump is located. The pump includes a nozzle, which is provided with a bacterial filter membrane for preventing bacteria from entering the bottle. The pore size of the bacterial filter membrane is less than or equal to 0.22 microns.

[0004] Most existing saline nasal sprayers are fixed-dose designs, meaning the spray volume is constant each time it is triggered and cannot be dynamically adjusted according to the patient's disease stage or actual needs. For example, during the acute phase of the disease (such as severe nasal congestion or peak inflammation), patients often require a larger dose of saline to fully clean and moisten the nasal cavity. During the recovery period or when symptoms are mild, excessive spraying may lead to excessive moistening of the nasal mucosa or waste of medicine, or even cause discomfort. In addition, special populations such as children and the elderly have large differences in their tolerance to spray volume, making it difficult for a fixed-dose design to meet individualized treatment needs. Summary of the Invention

[0005] The purpose of the present invention is to provide a physiological saline nasal sprayer that improves the utilization rate of liquid medicine. Its advantage is that the dosage can be adjusted according to the patient's condition stage and different applicable populations, meeting the different usage needs of patients and avoiding drug waste.
