[0002] At present, spray technology has been widely used in the pharmaceutical industry. Using spray devices to spray various drugs on the oral cavity, nasal cavity and skin surface, it has a great effect on the absorption and efficacy of drugs. Taking the nasal spray device as an example, medical evidence shows that daily nasal cleaning can effectively relieve various rhinitis symptoms such as nasal congestion and runny nose, and can reduce the invasion of bacteria and allergens into the nasal cavity, thereby improving the immunity of the respiratory tract.

[0003] In the existing dual-power nasal spray device, in order to enable the medicine to reach the lesion site deeper and farther in the nasal cavity, the user needs to blow air through the mouthpiece to assist the spray of the medicine. However, this process will inevitably cause medicine contamination. Impurities and bacteria contained in the blown air may cause infection or deterioration of the lesion site in the nasal cavity, thereby affecting the treatment effect. Utility Model Content

[0004] The utility model aims to provide a mouthpiece structure of a dual-power nasal spray, which can at least filter the air blown into the nasal spray, improve the cleanliness of the gas, and avoid infection or deterioration of nasal lesions.

DETAILED DESCRIPTION

[0047] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0048] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0049] Conventional nasal spray devices use a pressing operation to enable the material supply unit 7 to deliver the material to the nasal airway of the subject through the nasal holder 8. However, the device has the disadvantages of short delivery distance and poor material dispersion effect.

[0050] See also Figure 8As shown, the dual-power nasal spray described in the present application is different from conventional nasal spray devices in that a mouthpiece structure is installed on the nasal spray shell (i.e., the target shell 5), and the mouthpiece 2 is used to blow air to provide auxiliary power for the delivery of the substance, thereby increasing the delivery distance and improving the effect of the dispersion of the substance. Of course, the mouthpiece structure can be installed on other devices that require pressurization or airflow assistance, which is not limited here.

[0053] The mouthpiece 2 is configured to the nose of the subject, and its material is preferably a flexible member, for example, the mouthpiece 2 is made of silicone, and can be bent to adapt to different people. In the present application, the mouthpiece 2 needs to be connected to the cover plate 1, and is installed on the target shell 5 through the cover plate 1, and the mouthpiece 2 has an air blowing channel for blowing gas into the target shell 5.

[0054] The water-absorbing layer 3 is arranged on the inner wall of the mouthpiece 2, and is used to absorb water vapor in the blowing channel, so that the internal environment of the blowing channel is in a relatively dry state, thereby avoiding the adhesion of impurities and the growth of microorganisms. In the present application, the water-absorbing layer 3 can be a water-absorbing resin layer, which has good water absorption and no toxic effects. Of course, the water-absorbing layer 3 can also be made of some other medical-grade water-absorbing materials, which is not limited here.

[0055] The filter 4 is arranged at the outlet of the mouthpiece 2, and is used to filter the gas blown into the target housing 5. In the present application, the filter 4 can be a filter element, a filter screen, etc., but the filtering accuracy of the filter 4 must be less than or equal to 0.1 mm, which is sufficient to filter most impurities or bacteria contained in the gas, thereby ensuring the purity of the gas and avoiding affecting the spray treatment effect.
