[0002] The pulmonary route has been widely studied for the diagnosis and treatment of pulmonary and extrapulmonary diseases, such as asthma, tuberculosis, emphysema, and bronchitis. Pulmonary and nasal administration are ideal routes of administration for the local treatment of pulmonary and nasal diseases. Currently, in animal experiments, most of the drugs are injected into the animal's mouth through gun tips and pipettes, but the traditional gun tips are hard and easy to damage the oral mucosa. In addition, due to the large diameter of the gun tip, the drug solution is dripped too quickly, resulting in too much drug solution remaining in the mouth and affecting the absorption of the drug solution. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, such as: currently, when conducting animal experiments, most of the time, the drug solution is injected into the animal's mouth through a gun tip and a pipette, but the traditional gun tip has a high hardness and is easy to damage the oral mucosa, and because the diameter of the gun tip is too large, the drug solution is dripped too quickly, resulting in too much drug solution remaining in the oral cavity, and affecting the absorption of the drug solution, and thus an oropharyngeal injection drug delivery tool is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Preferably, the upper surface of the sealing cover is fixedly connected to the exhaust pipe, the inner wall of the exhaust pipe is fixedly connected to a support ring, the upper surface of the support ring is fixedly connected to a spring, the upper surface of the spring is fixedly connected to a sealing ball, the surface of the sealing ball is fitted with a sealing ring, and the surface of the sealing ring is fixedly connected to the surface of the exhaust pipe.

[0010] Preferably, the inner diameter of the sealing ring is smaller than the diameter of the sealing ball, the diameter of the sealing ball is smaller than the inner diameter of the exhaust pipe, and the center of the sealing ring is located below the center of the sealing ball.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model arranges the flexible rubber gun head into a cone shape so that the flexible rubber gun head can be directly extended into the bottom position of the tongue root, and the hollow rubber ball at the bottom end of the flexible rubber gun head can prevent the animal tissue from being scratched by the flexible rubber gun head. At the same time, when the air groove on the medicine pusher is opened, the elastic air bag pushes the medicine liquid in the liquid storage rubber bag when it is restored, so that the animal can directly absorb the medicine liquid in the flexible rubber gun head into the lungs through the airflow generated by breathing, and then the medicine liquid can quickly enter the lungs, thereby reducing the residual amount of the medicine liquid in the oral cavity and improving the absorption efficiency of the medicine liquid.

[0013] The utility model is provided with an exhaust pipe, a support ring, a spring, a sealing ball and a sealing ring, wherein when a user squeezes the liquid storage rubber bag to squeeze the elastic airbag, a thrust of the air on the sealing ring causes a gap to be generated between the sealing ring and the sealing ring, and the air in the elastic airbag is discharged through the exhaust pipe; at the same time, after the air in the elastic airbag is discharged, a pulling force of the spring on the sealing ball causes the sealing ball to be in close contact with the sealing ring, and the air outside the elastic airbag cannot enter the elastic airbag, and further, the exhaust pipe, the support ring, the spring, the sealing ball and the sealing ring cooperate to facilitate the user to discharge the air in the elastic airbag.
