[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0021] This utility model provides a technical solution, please refer to Figure 1-3 :

[0022] An adjustable oral medication dispenser includes a medicine tube 1 with a nozzle 2 fixed thereto. Both the medicine tube 1 and nozzle 2 are made of transparent materials, making it easy to see the position of the gel medication inside the medicine tube 1 and nozzle 2. A cavity 3 is defined within the medicine tube 1, communicating with the interior of the nozzle 2. A piston 11 is slidably connected to the cavity 3, and a connecting rod 10 is fixed to the sidewall of the piston 11. An air hole 5 is defined in the medicine tube 1, connected to the cavity 3, and sealed by a sealing member. Furthermore, a position limiting member is provided on the medicine tube 1 for limiting the position of the piston 11. When the air hole 5 is sealed, pushing the connecting rod 10 causes the piston 11 to move within the cavity 3 until the piston 11 pushes the medication in the cavity 3, causing it to flow out of the nozzle 2. Example

[0023] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the closure includes an annular groove 4 provided on the medicine tube 1, and a chute 6 provided on the annular groove 4, a circular ring 7 slidably connected to the annular groove 4, and a slider 8 slidably connected to the chute 6 fixed to the circular ring 7, and an elastic sealing ring is provided on the portion where the circular ring 7 and the annular groove 4 are slidably connected. A protruding push block 9 is fixed to the circular ring 7, which can facilitate the movement of the circular ring 7 in the annular groove 4. When the circular ring 7 blocks the air hole 5, the air hole 5 can be closed, isolating the cavity 3 from the outside. When the piston 11 moves in the cavity 3, it squeezes the medicine in the cavity 3 to flow out from the medicine nozzle 2, thereby facilitating the administration of the medicine to the patient's pharynx. Example

[0024] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the limiting member includes a screw block 14 that is threadedly connected to the cavity 3, and a cover plate 15 that abuts the side wall of the medicine tube 1 is fixed to the screw block 14. The screw block 14 and the cover plate 15 are both slidably connected to the connecting rod 10. An end block 12 is fixed to the end of the connecting rod 10. A spring 13 is sleeved on the connecting rod 10, and one end of the spring 13 abuts the cover plate 15, and the other end abuts the end block 12. The elastic force of the spring 13 pushes the end block 12 away from the cover plate 15. After the screw block 14 is threadedly connected to the cavity 3, it can limit the piston 11 so that the piston 11 cannot escape from the cavity 3 when moving in the cavity 3.

[0025] In summary, when the applicator provided in this embodiment is used to apply medication to the patient's pharynx, the push block 9 is used to push the ring 7 until it blocks and seals the ring 7. The gel medication is squeezed into the cavity 3 of the medicine tube 1. The piston 11 is then inserted into the cavity 3, and the cover plate 15 is rotated to connect the screw block 14 to the cavity 3 through threads.

[0026] The medicine mouthpiece 2 is inserted into the patient's pharynx, and at this time the medicine mouthpiece 2 is located outside the patient's oral cavity. Since the medicine mouthpiece 2 is long, there is no need to worry that the medicine mouthpiece 2 cannot administer medicine to the patient's pharynx.

[0027] The end block 12 pushes the connecting rod 10 to move, which causes the piston 11 to move in the cavity 3. The piston 11 causes the medicine in the cavity 3 to flow out through the medicine nozzle 2 and into the patient's pharynx, thus completing the drug administration.

[0028] When piston 11 is unable to squeeze the medicine out of nozzle 2, end block 12 can be pulled to move piston 11 away from cavity 3 until piston 11 moves past pore 5. Push block 9 can then push ring 7 to move, exposing pore 5. Piston 11 can then be pushed until it abuts screw block 14. As piston 11 moves, ambient air fills cavity 3 through pore 5.

[0029] Push the ring 7 to move by the push block 9, so that the air hole 5 is closed again. Now, the piston 11 can be pushed to move again by the end block 12, until the piston 11 squeezes the medicine in the medicine mouth 2 out.

[0030] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
