Description

Technical Field

[0001] This utility model relates to the field of ocular drug delivery technology, specifically a portable electronic atomizing drug delivery device that can reduce drug residue rate. Background Technology

[0002] Currently, when applying eye medication, the usual method is to drop the eye drops directly into the eye. However, it's difficult to aim the drops precisely at the eye, and improper application can easily cause contact with the eye. To reduce the hassle of applying eye medication, a nebulizer has been developed. This device atomizes the medication and delivers it directly to the eye, allowing for easy self-administration at home.

[0003] When administering medication to the eyes via nebulizer, medication residue remains inside the device after use, making it difficult to disassemble and clean. Over time, this can cause contamination inside the device, affecting its future use. Therefore, a portable electronic nebulizer that reduces medication residue is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a portable electronic atomizer that reduces drug residue, solving the problem of drug residue remaining inside the atomizer and causing internal contamination over time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable electronic nebulizer for reducing drug residue, comprising a drug delivery device housing and a drug tank located inside the drug delivery device housing.

[0011] Beneficial effects

[0012] This invention provides a portable electronic nebulizer for drug delivery that reduces drug residue. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model drives the trapezoidal block to move to the left by rotating the threaded rod, so that the trapezoidal block no longer squeezes the inclined plate. The inclined plate will fall out of the limiting groove and no longer block the limiting plate. Then, the medicine bottle is rotated to drive the threaded bottle mouth to rotate out of the liquid inlet. The limiting plate is pulled to drive the medicine tank to move and move the medicine tank out of the medicine dispenser shell. This makes it easy to disassemble the medicine tank and clean the inside of the medicine tank, reducing the residual rate of medicine inside the medicine dispenser.

[0014] (2) This utility model uses an integrated drug delivery device to directly target the drug solution atomized by the ultrasonic atomizing sheet to the eyes for treatment, making it more convenient to use and easier to carry. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a portable electronic atomizer for drug delivery that reduces drug residue, comprising a drug delivery device shell 1 and a drug tank 2 located inside the drug delivery device shell 1. A limiting plate 3 is fixedly connected to one side of the drug tank 2. One side of the limiting plate 3 penetrates through the drug delivery device shell 1 and extends to the outside of the drug delivery device shell 1. A rectangular opening adapted to the limiting plate 3 is provided on one side of the drug delivery device shell 1. A limiting mechanism 4 is provided at the lower part of the inside of the drug delivery device shell 1. A corresponding limiting mechanism 4 is provided at the bottom of the limiting plate 3. The device is equipped with a limiting groove 5. An ultrasonic atomizing plate 6 is fixedly installed on one side of the medicine tank 2 through an opening. The ultrasonic atomizing plate 6 is model TB-P20 and is electrically connected to the battery inside the drug delivery device housing 1. It is controlled by a control switch. A medicine bottle 7 is set at the top inside the drug delivery device housing 1. The bottom of the medicine bottle 7 is connected to a threaded bottle mouth 8. The top of the medicine tank 2 is provided with a liquid inlet 9 that matches the threaded bottle mouth 8. The other side of the drug delivery device housing 1 is provided with an installation port 10 that matches the ultrasonic atomizing plate 6.

[0023] It should be noted that when applying medication to the eyes via nebulization, the entire medication dispenser housing 1 should be oriented downwards, that is, the ultrasonic nebulizer 6 should be oriented downwards, and the medication in the medication tank 2 should be positioned above the ultrasonic nebulizer 6, so that any remaining medication can fully contact the ultrasonic nebulizer 6 and be completely atomized.

[0024] Furthermore, to facilitate the disassembly and cleaning of the medicine tank 2, the limiting mechanism 4 includes a threaded rod 41. One end of the threaded rod 41 is rotatably connected to one side of the inner cavity of the medicine dispenser shell 1 via a bearing. A trapezoidal block 42 is threaded onto the surface of the threaded rod 41. A first sliding groove 43 is provided at both the front and rear of the inner cavity of the medicine dispenser shell 1. The interior of the first sliding groove 43 is slidably connected to the trapezoidal block 42 via a slider. A second sliding groove 44 is provided on one side of the inner cavity of the medicine dispenser shell 1 and below the limiting plate 3. An inclined plate 45 adapted to the limiting groove 5 is slidably connected to the interior of the second sliding groove 44 via a slider.

[0025] Furthermore, in order to facilitate the compression and limiting of the medicine bottle 7, a threaded hole 11 is provided on the top of the medicine dispenser shell 1. A flip cover plate 12 is connected to the inside of the threaded hole 11, and a rubber pad 13 that is compatible with the medicine bottle 7 is fixedly connected to the bottom of the flip cover plate 12.

[0026] Furthermore, in order to facilitate the removal of the medicine bottle 7, a first magnet 15 is fixedly connected to the surface of the flip-top plate 12, and a second magnet 16 adapted to the first magnet 15 is fixedly connected to the top of the medicine dispenser shell 1 through an opening. The first magnet 15 and the second magnet 16 are attracted to each other by opposite poles.

[0027] Furthermore, to facilitate the installation of the liquid medicine tank 2, guide plates 14 are fixedly connected to the other side of the inner cavity of the drug delivery device shell 1, both above and below the liquid medicine tank 2.

[0028] When in use, the liquid medicine in the medicine bottle 7 enters the medicine tank 2 through the threaded bottle mouth 8. The ultrasonic atomizing plate 6 is activated by control, and the ultrasonic atomizing plate 6 atomizes the liquid medicine in the medicine tank 2 to perform atomized drug delivery treatment to the eyes.

[0029] When the medicine in the medicine bottle 7 is used up, the first magnet 15 and the second magnet 16 on the flip cover 12 are separated by rotating the flip cover 12, so that the rubber pad 13 is taken out of the medicine dispenser housing 1 along with the flip cover 12. Then, the medicine bottle 7 is rotated to drive the threaded bottle mouth 8 to rotate and rotate the threaded bottle mouth 8 out of the liquid inlet 9, so that the medicine bottle 7 can be taken out to add medicine. Then, the limiting plate 3 is pulled to the left, and the limiting plate 3 drives the medicine tank 2 to move out of the medicine dispenser housing 1 to clean the inside of the medicine tank 2 and reduce the residue of medicine inside the medicine tank 2.

[0030] Next, insert the cleaned medicine tank 2 between the two guide plates 14 inside the dispensing device housing 1, and rotate the threaded rod 41. The threaded rod 41 drives the trapezoidal block 42 to move. The inclined surface of the trapezoidal block 42 presses against the inclined surface of the inclined plate 45, pushing the inclined plate 45 to move upward, so that the inclined plate 45 is inserted into the limiting groove 5 to limit and fix the limiting plate 3. Then insert the medicine bottle 7 into the dispensing device housing 1, so that the threaded bottle mouth 8 rotates into the medicine tank 2 for easy use next time.
