[0018] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it is understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
[0019] Referring to Figures 1-5 The present application provides an embodiment: a mouse nose dropper, comprising a pipe body 1, a liquid storage pipe 2 mounted on the pipe body 1; one end of the pipe body 1 is provided with a droplet 4, and a support table 8 is provided inside the pipe body 1, and a through hole 7 is further provided on the support table 8; one end of the liquid storage pipe 2 is attached to the support table 8 by the provided sealing gasket 5, and the sealing gasket 5 is provided with a liquid outlet hole 6, and the liquid outlet hole 6 is communicated with the through hole 7, so as to make the liquid in the liquid storage pipe 2 flow to the droplet 4.
[0020] In specific use, a pipette or dropper is used to take a fixed volume of OVA solution required for each nostril of the experimental mouse, the OVA solution is carefully injected into the liquid storage pipe 2, then the droplet 4 is fitted with the mouse nostril, and the liquid storage pipe 2 is driven to move until the liquid outlet hole 6 is communicated with the through hole 7, so as to make the liquid in the liquid storage pipe 2 flow to the droplet 4, and then the reagent in the liquid storage pipe 2 flows into the mouse nasal cavity, so as to complete the liquid dropping work. Wherein, when the mouse is dripped again, the required amount of medicament is poured into each nose dropper, then each nose dropper only drips one nostril, so that the amount of medicament dropped can be further stabilized.
[0021] Therefore, compared with the pipette, the required amount of nose dropping reagent is poured into the liquid storage pipe 2, and then dripped into the mouse nasal cavity through the droplet 4, so as to have the advantages of convenient operation and rapid and convenient liquid dropping, especially the quantitative liquid dropping, and the droplet is inserted into the nasal cavity, which can effectively solve the problems of insufficient liquid dropping and liquid outflow interfering with the test results.
[0022] Further, since the sealing gasket 5 is further provided with a shaft pin 11, and the liquid storage pipe 2 is rotatably installed on the support table 8 through the shaft pin 11, the liquid storage pipe 2 can rotate around the shaft pin 11 as the rotation center axis, so as to facilitate the smooth and reliable conduction of the liquid outlet hole 6 and the through hole 7; under normal circumstances, the liquid outlet hole 6 and the through hole 7 are in a non-conduction state.
[0023] Further, since the material of the shaft pin 11 is elastic rubber, and the length of the shaft pin 11 is less than the thickness of the support table 8, and the shaft pin 11 is contracted to make the sealing gasket 5 tightly press on the support table 8. Therefore, since the shaft pin 11 is elastic, the sealing gasket 5 can be tightly pulled on the support table 8 after the shaft pin 11 is contracted, so that the sealing gasket 5 and the support table 8 are relatively sealed to avoid the leakage of the droplet.
[0024] On the basis of the above scheme, since the end of the liquid storage pipe 2 away from the droplet orifice 4 is connected with the driving part 3, the liquid storage pipe 2 can be easily and conveniently rotated by the driving part 3, so that the droplet can quickly flow to the nasal cavity, to further improve the speed of the mouse nasal cavity droplet. In addition, the inside of the driving part 3 is a hollow structure, and the droplet can be further quickly discharged by extruding the driving part 3.
[0025] Further, the liquid storage pipe 2 is connected with the connecting hole 10 of the driving part 3 through the connecting part 9, so that the driving part 3 can be used to cover the liquid storage pipe 2 to prevent the leakage of the droplet after the driving part 3 is disassembled.
[0026] In addition, since the cross section of the connecting part 9 is a polygon, preferably, the cross section of the connecting part 9 is a hexagon. Therefore, the driving part 3 can be connected with the liquid storage pipe 2, and the driving part 3 can reliably rotate the liquid storage pipe 2.
[0027] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
