[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3This utility model provides an embodiment of an ENT medication delivery device, comprising a housing 1, a threaded cylinder 2 fixedly connected to the upper surface of the housing 1, a spray pump 3 threadedly connected inside the threaded cylinder 2, the spray pump 3 being detachable by quick rotation, a suction tube 4 fixedly connected to the bottom end of the spray pump 3, allowing the user to extract the medication from inside the housing 1 by pressing the top of the spray pump 3 through the suction tube 4, the bottom end of the suction tube 4 penetrating through the housing 1, and a spray tube 5 fixedly connected to the left output end of the spray pump 3, allowing the medication extracted by the spray pump 3 to be sprayed out through the spray tube 5, so that the medication can accurately reach the patient's affected area. The above structure is a prior art in this field and will not be described in detail here. A storage cylinder 6 is provided inside the housing 1 for storing the medication.
[0034] Reference Figures 3-5 A fixed tube 7 is fixedly connected to the left side of the upper surface of the liquid storage cylinder 6. The medicine can be added into the interior of the liquid storage cylinder 6 through the fixed tube 7. The bottom end of the suction tube 4 passes through the fixed tube 7 into the interior of the liquid storage cylinder 6. The fixed tube 7 is rotatably connected to the center of the inner top surface of the outer shell 1 through the bearing 8. The liquid storage cylinder 6 is rotatably connected to the interior of the outer shell 1 through the cooperation of the fixed tube 7 and the bearing 8. At the same time, the liquid storage cylinder 6 and the outer shell 1 rotate eccentrically. The outer wall of the suction tube 4 is in contact with the inner wall of the liquid storage cylinder 6. A base plate 9 is fixedly connected to the bottom surface of the liquid storage cylinder 6. When the base plate 9 rotates, it can drive the liquid storage cylinder 6 to rotate synchronously. The upper surface of the base plate 9 is in contact with the bottom surface of the outer shell 1. The outer wall of the base plate 9 is provided with anti-slip texture 10. The anti-slip texture 10 can increase the friction between the base plate 9 and the user's arm and prevent slippage.
[0035] When the user needs to tilt the device, the base 9 can be rotated to drive the liquid storage cylinder 6 to rotate synchronously, so that the side of the liquid storage cylinder 6 away from the suction pipe 4 is away from the tilt direction, so that the liquid inside the liquid storage cylinder 6 is closer to the suction pipe 4, so that the device can still spray even when tilted at a negative angle or in a horizontal state, improving the adaptability of the device.
[0036] A limiting unit is provided above the chassis 9. The limiting unit includes a fixing rod 111, which is fixedly connected to the upper surface of the chassis 9. When the chassis 9 rotates, it can drive the fixing rod 111 to rotate synchronously. A fixing ring 112 is fixedly connected inside the outer shell 1. The fixing ring 112 is located directly above the fixing rod 111. Several rubber rods 113 are fixedly connected in a circular array on the bottom surface of the fixing ring 112. The bottom surface of the rubber rods 113 is higher than the upper surface of the fixing ring 112. The fixing ring 112 is located between adjacent rubber rods 113. In the gap, when the chassis 9 rotates and drives the fixed rod 111 to rotate synchronously, the fixed rod 111 needs to squeeze the rubber rod 113. It can only move after overcoming the yield strength of the rubber rod 113. When the liquid storage cylinder 6 is in a horizontal state or tilted at a small angle, the fixed ring 112 does not need to rotate. At this time, the rubber rod 113 will limit the fixed rod 111, so that the fixed rod 111 and the chassis 9 remain stable, reducing shaking and noise, improving the stability of the device during use and the user experience.
[0037] Reference Figure 1 and Figure 6 An annular shell 12 is fixedly connected to the upper surface of the chassis 9. When the chassis 9 rotates, it can drive the annular shell 12 to rotate synchronously. The cross-section of the annular shell 12 is L-shaped. A limiting ring 13 is fixedly connected to the outer wall surface of the outer shell 1. The annular shell 12 is rotatably connected to the outer side of the limiting ring 13. The annular shell 12 can rotate outside the limiting ring 13. At the same time, the limiting ring 13 can limit the movement of the annular shell 12, which can prevent the limiting ring 13 from moving downward. Thus, through the cooperation of the annular shell 12 and the limiting ring 13, the movement of the chassis 9 can be further limited, preventing the chassis 9 from shifting downward. This can improve the stability of the liquid storage cylinder 6 and the chassis 9. A triangular mark 14 is opened on the right side of the upper surface of the annular shell 12. The triangular mark 14 corresponds to the side of the liquid storage cylinder 6 away from the suction pipe 4. The user can accurately judge the position of the liquid storage cylinder 6 through the triangular mark 14, which can improve the efficiency of the device.
[0038] Working principle: When the user needs to use the drug delivery device horizontally or at a large angle, the base 9 can be rotated to rotate the liquid reservoir 6, so that the side of the liquid reservoir 6 away from the suction tube 4 is away from the tilt direction of the device. The user can accurately grasp the position of the liquid reservoir 6 through the triangular mark 14, improving the accuracy of the rotation of the liquid reservoir 6. At this time, after the drug delivery device is tilted, the liquid inside the liquid reservoir 6 can move towards the suction tube 4, so that the device can still be used for spraying when tilted at a negative angle or in a horizontal state, thus increasing the range of use of the device. When the user needs to use the drug delivery device vertically or at a small angle, the fixed ring 112 and the rubber rod 113 can limit the fixed rod 111 and the base 9, so that the base 9 and the liquid reservoir 6 can remain stable during use, reducing shaking and noise, and improving the user experience.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
