[0002] ENT care is a series of health care and treatment auxiliary measures centered around the ears, nose, and throat, and is of great significance to maintaining human health. In the care and treatment of ENT diseases, ear canal medication is a common and important treatment method. At present, ear canal medication mainly adopts traditional methods such as dropper instillation, syringe injection, and cotton swab application. When using a dropper, it is difficult to accurately control the amount of medicine dripped in, and it is easy to administer too much or too little medicine, which not only affects the treatment effect, but may also cause adverse reactions due to drug overdose. Although syringe injection can control the amount of medicine to a certain extent, the operation process is relatively complicated and has high technical requirements for medical staff. If the force is not properly controlled during injection, it may cause damage to the ear canal. It is difficult to apply the medicine evenly inside the ear canal with a cotton swab, resulting in the medicine not being able to fully contact the lesion, reducing the utilization rate of the medicine and the treatment effect. For this reason, an ear canal drug delivery device for ENT care is proposed to solve the above problems. Summary of the Invention

[0017] The present invention achieves precise, quantitative drug delivery through the coordination of a drug squeezing device and a quantitative drug dispensing device. The drug squeezing roller squeezes the soft drug storage shell to squeeze out the drug, while the fixed volume of the quantitative drug cartridge ensures a consistent amount of drug is delivered to the drug delivery cartridge each time. This avoids the difficulty of controlling drug dosage with a dropper, which can lead to overdosing or underdosing, impacting treatment efficacy, and even causing adverse reactions, providing patients with more scientific and effective treatment.

[0018] The present invention utilizes a rotation-assisted device for squeezing and rotating the medicine applicator, enabling the medicine dispensing tube to automatically rotate during medication administration. When the medicine pusher pushes the medicine, the rotation drives the extrusion block to slide within the extrusion groove on the inner wall of the active rotating cylinder. The force of the specifically shaped groove wall causes the active rotating cylinder to rotate, which in turn drives the medicine dispensing tube to rotate, evenly applying the medicine to the ear canal wall. This solves the problem of traditional cotton swab application, which makes it difficult to evenly apply the medicine, resulting in insufficient contact with the lesion and low utilization rate, and better maximizes the efficacy of the medicine.

[0033] The medicine squeezing device 6 is provided on a side of the medicine storage housing 1 away from the dispensing / squeezing housing 2 and is detachable and used to squeeze the medicine in the medicine storage housing 11;

[0034] A quantitative medicine dispensing device 7 is provided in the dispensing cavity of the dispensing / extruding housing 2 and is used to quantify the medicine extruded each time;

[0035] The medicine extrusion rotation auxiliary device 8 is arranged in the rotation chamber of the material dispensing / medicine extrusion housing 2, and is used to realize the rotation of the medicine dispensing smear tube 3 when squeezing the medicine, so that the medicine dispensing smear tube 3 can be applied more evenly.

[0036] according to Figure 1 、 Figure 4 and Figure 5 As shown, the medicine squeezing device 6 includes a sealing card shell 12, a mounting push plate 13, a medicine squeezing roller 14 and a rotating rod 15. The medicine storage housing 1 is fixedly connected to the side of the material distribution / medicine squeezing housing 2 with a sealing card shell 12. The sealing card shell 12 is a detachable design. The inner wall of the sealing card shell 12 away from the material distribution / medicine squeezing housing 2 is movably connected with the medicine squeezing rod 5. One end of the medicine squeezing rod 5 extends into the inner cavity of the sealing card shell 12 and is fixedly connected to the mounting push plate 13. The mounting push plate 13 is fixedly connected to two sets of plates on both sides away from the medicine squeezing device 6. The medicine squeezing roller 14 is rotatably connected between the two sets of plates. The mounting push plate 1 On one side of 3, the upper and lower ends of the first set of plates are fixedly connected with a third set of plates, and the third set of plates are rotatably connected with a rotating rod 15. The detachable structure of the sealing card shell 12 facilitates the disassembly of the medicine storage shell 11 for medicine filling; when the medicine squeezing rod 5 is pushed, the installation push plate 13 is driven to move, so that the medicine squeezing roller 14 approaches the medicine storage shell 11. At the same time, the rotating rod 15 cooperates with the gear tooth transmission structure to allow the medicine squeezing roller 14 to rotate synchronously during the approach process. By using the roller extrusion method, the medicine can be squeezed out of the medicine storage shell 11 to the quantitative medicine dispensing device more evenly and efficiently, providing a basis for subsequent quantitative drug administration.

[0037] Furthermore, two worms 16 are provided on the side of the rotating rod 15, and one end of the rotating shaft of the medicine squeezing roller 14 extends to the other side of the first set of plates and is fixedly connected to a turntable 19. The turntable 19 is transmission-connected to the worm 16. The two worms 16 rotate in opposite directions, and the two sets of medicine squeezing rollers 14 rotate in opposite directions. Gears 17 are fixedly connected to the upper and lower ends of the side of the rotating rod 15. A plurality of teeth 18 with equal spacing are fixedly connected to the inner wall of the sealing card shell 12 and the inner wall of the same side of the medicine storage shell 1 corresponding to the two pairs of plates in the third group. The teeth 18 and the gears are connected. The wheels 17 are meshed with each other. At the same time, a plurality of toggle posts arranged in an annular shape and at equal distances are fixedly connected to the turntable 19. The toggle posts can realize the rotation of the turntable 19 under the extrusion action of the inclined surface of the worm 16. The design of the above structure makes it possible to rotate the turntable 19 when the medicine squeezing rod 5 is pushed. The rotating rod 15 rotates under the meshing action of the gear 17 and the teeth 18, and then drives the medicine squeezing roller 14 to rotate in opposite directions through the transmission of the worm 16 and the turntable 19, thereby squeezing and taking medicine from the medicine storage shell 11. At the same time, the transmission relationship is cleverly utilized to ensure that the medicine squeezing roller 14 always maintains an effective squeezing state during the movement.

[0038] according to Figure 6As shown, a medicine squeezing groove is provided below the corresponding sliding groove in the inner cavity of the medicine storage shell 1, and a medicine pushing rod 20 is movably connected in the medicine squeezing groove, and the medicine pushing rod 20 is fixedly connected to the thumb pushing plate 4 through an extension plate, and a rotating transmission plate 21 is movably connected to one end of the sliding groove close to the material dispensing / medicine squeezing shell 2. The rotating transmission plate 21 is movably inserted into the side of the material dispensing / medicine squeezing shell 2 and extends to the inner cavity of the material dispensing / medicine squeezing shell 2 and is fixedly connected to a push rod 27. This structure realizes the linkage between the thumb pushing plate 4 and the medicine pushing rod 20 and the rotating transmission plate 21. When the thumb pushing plate 4 is operated, it can not only push the medicine pushing rod 20 to push the medicine, but also drive the push rod 27 through the rotating transmission plate 21, thereby providing power transmission for the operation of subsequent quantitative medicine dispensing device and medicine squeezing rotation auxiliary device.

[0039] according to Figure 1 and Figure 7 As shown, the quantitative medicine dispensing device 7 includes a connecting sleeve 22, a first mounting plate 23, a sealing baffle 24, a lifting block 25 and a quantitative medicine cartridge 26. The connecting sleeve 22 is fixedly connected to the inner wall of the medicine storage housing 1 on one side close to the dispensing / extruding medicine housing 2. The other end of the connecting sleeve 22 extends to the inner cavity of the dispensing / extruding medicine housing 2 and is fixedly connected to the first mounting plate 23. The first mounting plate 23 is fixedly connected to the inner wall of the dispensing / extruding medicine housing 2 on one side close to the medicine storage housing 1. A movable groove is provided on the front side of the first mounting plate 23. A lifting block 25 is movably connected to the upper side of the plate 23, and a quantitative medicine cartridge 26 is fixedly connected to the side of the lifting block 25 away from the medicine storage shell 1. A sealing baffle 24 is fixedly connected to the front side of the first mounting plate 23. The sealing baffle 24 is U-shaped and matches the quantitative medicine cartridge 26. By pressing the medicine dispensing button 10, the lifting block 25 and the quantitative medicine cartridge 26 are driven to move, and the fixed volume of the quantitative medicine cartridge 26 is used to achieve drug quantitative dispensing, and the sealing baffle 24 seals the quantitative medicine cartridge 26 when no quantitative medicine is taken, to prevent drug leakage and contamination.

[0040] Furthermore, one side of the first mounting plate 23 is fixedly connected to the connecting sleeve 22, and is provided with a corresponding through groove that is connected to each other. The upper side of the lifting block 25 is provided with a groove for the push rod 27 to move. The bottom of the lifting block 25 is fixedly connected with a connecting plate 28, and the lower end of the connecting plate 28 is fixedly connected to the medicine dispensing button 10. The push rod 27 can smoothly pass through the groove of the lifting block 25 when pushing the medicine, and at the same time, the action of pressing the medicine dispensing button 10 is accurately transmitted to the lifting block 25 and the quantitative medicine cartridge 26, ensuring that the quantitative medicine dispensing process is stable and reliable.

[0041] according to Figure 1 、 Figure 8 and Figure 9As shown, the medicine squeezing rotation auxiliary device 8 includes a first rotating cylinder 30, an active rotating cylinder 31, a limiting ring 33, a second return spring 34 and a medicine feeding connecting cylinder 36. The side surface of the medicine feeding cylinder 29 corresponds to the end away from the medicine storage shell 1 and is movably sleeved with the first rotating cylinder 30. The outer side surface of the first rotating cylinder 30 is movably sleeved with the active rotating cylinder 31. The end of the active rotating cylinder 31 away from the medicine storage shell 1 is fixedly connected to the medicine feeding connecting cylinder 36. The end of the medicine feeding cylinder 29 away from the medicine storage shell 1 and the medicine feeding connecting cylinder 36 are fitted with a leak-proof rubber ring. A second return spring 34 is movably sleeved in the inner cavity of a rotating cylinder 30, and the two ends of the second return spring 34 are respectively against the inner wall of the first rotating cylinder 30 and the inner wall of the active rotating cylinder 31. When the medicine pushing rod 20 pushes the first rotating cylinder 30 to move, the force generated by the extrusion block 32 sliding in the extrusion inner groove 35 on the inner wall of the active rotating cylinder 31 drives the active rotating cylinder 31 to rotate, thereby rotating the medicine delivery connecting cylinder 36 and the medicine discharging smear tube 3 to achieve uniform application of the medicine. After the operation is completed, the second return spring 34 resets the first rotating cylinder 30 to facilitate the next use.

[0042] Furthermore, a plurality of extrusion blocks 32 are fixedly connected to the side of the extrusion block 32 away from the medicine storage shell 1, and an extrusion inner groove 35 is provided on the inner wall of the active rotating cylinder 31. The extrusion inner groove 35 is composed of a plurality of identical and annular equidistantly distributed specific sliding grooves. The specific sliding groove is a rectangular straight groove in the upper half and an inclined V-shaped in the lower half. The multiple specific sliding grooves are connected, so that when the extrusion block 32 slides in it, the active rotating cylinder 31 forms a rotation action, and the outer side surface of the active rotating cylinder 31 is fixedly connected A limiting ring 33 is connected, and the limiting ring 33 is slidably engaged on the inner wall of the material dispensing / drug extrusion shell 2. The first rotating cylinder 30 extends out of the inner cavity of the active rotating cylinder 31 at one end close to the drug storage shell 1, and is fixedly connected to the push rod 27. Through the cooperation of the specially shaped extrusion inner groove 35 and the extrusion block 32, the linear motion of the push rod 27 is converted into the rotational motion of the active rotating cylinder 31. The limiting ring 33 ensures the stability and accuracy of the rotation of the active rotating cylinder 31, ensuring that the drug dispensing smear tube 3 can reliably realize the function of evenly applying the drug.

[0043] The effect achieved by the entire mechanism is as follows: when using the device, the device can be operated by holding the drug storage shell 1 with one hand, placing four fingers in the holding groove 9, and placing the thumb on the thumb push plate 4 to facilitate the drug squeezing operation. Before using the device, first remove the sealing card shell 12 and take out the drug storage shell 11 from the drug storage shell 1. Since the drug storage shell 11 is made of soft material, it is convenient for subsequent drug squeezing operations. After filling the drug storage shell 11 with medicine, the drug storage shell 11 is rotated and fixed on the connecting sleeve 22, and then the sealing card shell 12 is re-fixed to its original position, and then the drug squeezing preparation stage can be entered.

[0044] When medication is to be squeezed out, the medication squeezing device 6 is first activated: the medication squeezing rod 5 is pushed, which drives the mounting push plate 13 to translate. During this translation, the rotating rod 15 on the front side of the mounting push plate 13 rotates due to the meshing of the gears 17 at the upper and lower ends with the teeth 18 on the sealing card shell 12 and the inner wall of the medication storage shell 1. As the rotating rod 15 rotates, the two worm gears 16 on its side drive the rotating disk 19 to rotate, and the two rotating disks 19 respectively drive the two medication squeezing rollers 14 connected to it to rotate in opposite directions. When the medication squeezing rollers 14 move toward the medication storage shell 11, the two medication squeezing rollers 14 squeeze it, utilizing the deformation characteristics of the soft medication storage shell 11 to squeeze out the medication inside. The medication enters the metering cartridge 26 through the connecting sleeve 22. Since the volume of the metering cartridge 26 is fixed, when the medication fills its inner cavity, the resistance increases, completing a quantitative medication extraction, ensuring that the amount of medication squeezed out each time is fixed.

[0045] After dispensing the drug in a fixed amount, the finger placed in the grip groove 9 presses the drug dispensing button 10, while the thumb squeezes the thumb push plate 4 to squeeze the drug. Specifically, when the drug dispensing button 10 is pressed, the button 10 presses upward against the lifting block 25 via the connecting plate 28, causing the lifting block 25 to move the metering cartridge 26 upward until it is flush with the drug delivery cartridge 29. At this point, the thumb rubs the thumb push plate 4, driving the drug push rod 20 to squeeze against the metering cartridge 26, pushing the drug in the metering cartridge 26 into the drug delivery cartridge 29. The drug dispensing button 10 is then released, and the connecting plate 28 returns to its original position under the action of the first return spring, completing the drug dispensing operation.

[0046] To ensure even medication application, continue rubbing the thumb push plate 4. This action drives the lower medicine push rod 20 further, pushing the medication in the medicine delivery barrel 29 toward the end of the medicine dispensing tube 3. Simultaneously, the medicine push rod 20, through the rotating transmission plate 21, drives the first rotating barrel 30 toward the inner cavity of the active rotating barrel 31. As the first rotating barrel 30 moves, the extrusion block 32 at its tail end slides within the extrusion groove 35 defined by the inner wall of the active rotating barrel 31. The extrusion groove 35 consists of a plurality of interconnected, circularly spaced, grooves, each with a rectangular upper portion and an inclined V-shaped lower portion. As the extrusion block 32 slides within the groove, the force exerted by the inclined V-shaped groove walls causes the active rotating barrel 31 to rotate. This rotation of the active rotating barrel 31 drives the medication delivery coupling barrel 36, which in turn rotates the medicine dispensing tube 3, which is connected to it. The medicine dispensing tube 3 rotates within the ear canal, evenly applying medication to the walls of the ear canal. After the operation is completed, the second return spring 34 drives the first rotating cylinder 30 to return to its original position under the action of elastic restoring force, preparing for the next medication. By repeating the above-mentioned operation of rubbing the thumb push plate 4, the medicine can be continuously evenly applied to meet the medication needs of ear canal care.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
