When in use, the medicine feeding body can be plugged into the nasal cavity and carried by the nasal cavity, the use is convenient, the appearance is not influenced, and the medicine is easy to be inhaled quickly and sufficiently.

Description

Intranasal medicator

This utility model relates to a kind of doser, particularly a kind ofly carries out administration by nasal cavity, a kind of intranasal medicator of treatment disease.

General volatile medicine and some other medicine can carry out administration by nasal cavity, absorb by Nasal Mucosa Absorption or by pulmonary, enter blood, the treatment disease.Clinically, general nasal-cavity administration is most to be adopted medicine is directly splashed into or put into the cotton balls that nasal cavity or handle contain medicine, the sponge kind pharmaceutical carrier is directly filled in the nasal cavity, this administering mode medicine carries inconvenience, dosage is also inaccurate, it carries out administration by a kind of doser marketed drugs " BITONG ", this device comprises shell, the top has the administration body in a hole, and the base formation, its highly about 50mm, an interim part was filled in nasal cavity when this device used, a part outside, should not put into nasal cavity and surpass half an hour, can not fill in nasal cavity and portably use, will hold on the other hand all the time during administration, use inconvenience by nasal cavity, most is exposed at the nasal cavity outside, influence attractive in appearancely, use repeatedly, also unhygienic.

When will providing a kind of use exactly, the purpose of this utility model can insert nasal cavity fully, the intranasal medicator easy to use that can carry by nasal cavity at nasal cavity.

This utility model is finished like this: it comprises shell, administration body, base, it is external that shell is enclosed within administration, base joins with shell under the administration body administration body is placed in the closed cavity that shell and base form, shell and base sealing administration body, the administration body has the administration body cavity in being, foraminous structure on the wall, administration body and base be connected to flexible connection.

The utility model has the advantages that: the administration body can place nasal cavity, is carried by nasal cavity, about the administration body is upper and lower around ventilation, make medicine can be fast, the suction of capacity and make medicine all can play therapeutical effect within a certain period of time; Structure such as cannelure, screw thread makes shell and base good seal, makes the inefficacy of should not volatilizing of storage life medicine.Volume is little, places the nasal cavity outside can't see, and does not affect the appearance, and opening shell during use, that the administration body is filled in nasal cavity is easy to use, can once use, and sanitation and hygiene, ring buckle is double to be done drawer structure or has drag hook or pull handle or backguy.Make the administration body easily pull out nasal cavity, can not fall into respiratory tract, volume is little, and is simple in structure, and cost is low, is easy to produce.

The utility model will be further described below in conjunction with the drawings and specific embodiments:
