Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a topical medication textile-based borneol gel applicator. Background Technology
[0002] Drug delivery devices are a type of medical device used to precisely deliver drugs to the site of action. They play an important role in healthcare and daily care. Their core function is to achieve precise control of drug dosage, stable delivery, and efficient action. Traditional drug delivery devices come in various forms. Electronically controlled drug delivery devices use sensors and microprocessors to achieve quantitative drug delivery, while manually squeezed drug delivery devices rely on human power to push the drug.
[0003] Check the power of the drug delivery device, the display screen, and all function buttons to ensure they are working properly. Confirm the sensor's working status. Select the appropriate syringe according to the doctor's order, draw up the required medication, and input parameters such as the drug delivery mode, infusion rate, and total dosage through the drug delivery device's control panel or connected terminal device. Connect the drug delivery device's output to the infusion tubing or injection needle. During the drug delivery process, observe the parameter changes, remaining medication, and operating status prompts on the drug delivery device's display screen in real time. After completing the drug delivery, turn off the drug delivery device and remove the syringe.
[0004] However, existing topical medication gel delivery methods mostly rely on electronic control or simple manual squeezing, which has many problems. Although electronically controlled dispensers can achieve quantitative dosage, the sensors are easily affected by environmental factors such as electromagnetic interference, humidity, and temperature changes, leading to decreased delivery accuracy or even equipment failure. Manual squeezing relies entirely on the operator's feel and experience, making it difficult to accurately control the dosage and resulting in large errors. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] This solves the problem of existing drug dosing and avoids the decrease in drug dosing accuracy caused by using sensors that are susceptible to environmental influences, thus improving the effectiveness of the device.
[0007] (II) Technical Solution
[0008] In view of the above-mentioned problems with quantitative drug administration, this utility model is proposed.
[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a topical medicine textile-based borneol gel applicator, comprising a body, two mirror-distributed rotating screws slidably connected to the inner wall of the body, a push plate threaded onto the outer wall of the rotating screws, an injection tube slidably connected to the inner wall of the push plate and engaging with the outer wall of the body, a circular plate fixedly connected to the outer wall of the injection tube and engaging with the inner wall of the body, two mirror-distributed circular sleeves slidably connected to the outer wall of the body, and a fitting groove provided on the outer wall of the body to facilitate the sliding connection of the injection tube to the outer wall.
[0010] As a preferred embodiment of the textile-based borneol gel applicator for external use according to this utility model, the inner wall of the device is provided with an installation groove to facilitate the sliding of the rotating screw. A drive motor is fixedly connected to the inner wall of the installation groove. A rotating shaft is fixedly connected to the output end of the drive motor. Two evenly distributed active bevel gears are fixedly connected to the outer wall of the rotating shaft.
[0011] As a preferred embodiment of the present invention, a textile-based borneol gel applicator for external use, wherein: the outer wall of the active bevel gear meshes with a driven bevel gear that is fixedly connected to the outer wall of the rotating screw; the inner wall of the body is fixedly connected with a plurality of evenly distributed guide posts that are slidably connected to the inner wall of the push plate; and the inner wall of the injection tube is slidably connected with a push rod that is slidably connected to the outer wall of the push plate.
[0012] As a preferred embodiment of the present invention, a textile-based borneol gel applicator for external use is provided, wherein: a movable groove is provided on the outer wall of the body to facilitate the sliding connection of a circular plate, an extrusion plate is slidably connected to the inner wall of the movable groove and is slidably connected to the outer wall of the circular plate, and an anti-slip pad is fixedly connected to the outer wall of the extrusion plate and is slidably connected to the outer wall of the circular plate.
[0013] As a preferred embodiment of the present invention, a textile-based borneol gel applicator for external use, wherein: two evenly distributed compression springs are connected between the outer wall of the compression plate and the inner wall of the moving groove; an operation panel is fixedly connected to the top of the device; and two mirror-distributed magnetic blocks are fixedly connected to the outer wall of the device.
[0014] As a preferred embodiment of the present invention, a textile-based borneol gel applicator for external use is provided, wherein: the inner wall of the body is provided with an arc-shaped groove that facilitates the sliding connection of the outer wall of the circular sleeve; both sides of the outer wall of the circular sleeve are fixedly connected with sliding blocks; the inner wall of the arc-shaped groove is provided with a limiting groove that facilitates the sliding of the outer wall of the sliding block; and the outer wall of the circular sleeve is fixedly connected with a magnetic sheet that fits against the outer wall of the magnetic block.
[0015] The beneficial effects of this utility model are:
[0016] 1. After the drive motor starts, the rotating screw is precisely rotated through the transmission of the active bevel gear and the driven bevel gear, which in turn drives the push plate to move smoothly along the guide column. This mechanical transmission method is not affected by environmental factors such as electromagnetic interference, temperature changes, and humidity fluctuations, and avoids drug delivery deviations caused by sensor signal errors. With stable mechanical transmission, the displacement distance of the push plate can be precisely controlled, thereby accurately controlling the amount of gel extruded. Whether it is micro-dose administration or conventional dose administration, high-precision operation can be achieved, thereby improving the accuracy and reliability of drug delivery and improving the effectiveness of the equipment.
[0017] 2. Regarding the installation and fixation of the injection tube, the drug delivery device is designed with multiple stabilizing structures. When the injection tube is inserted, the circular plate squeezes the trapezoidal squeezing plate. Under the action of the squeezing spring, the squeezing plate drives the anti-slip pad to fit tightly against the circular plate, using friction to achieve initial fixation and provide basic stable support for the injection tube. At the same time, it pushes the circular sleeve to rotate along the arc groove until the magnetic plate on the outer wall of the circular sleeve and the magnetic block on the outer wall of the device are precisely fitted. The magnetic force further enhances the fixation effect. The dual fixation methods complement each other, avoiding possible shaking or collisions caused by external forces during use, preventing the injection tube from becoming loose or shifting, and ensuring that the injection tube remains stable during drug delivery.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] Example 1
[0027] Reference Figure 1-3 This is the first embodiment of the present invention, which provides a topical medication textile-based borneol gel applicator, including a body 1. The inner wall of the body 1 is slidably connected to two mirror-distributed rotating screws 10. The rotating screws 10 are high-precision screws used to drive a push plate 2 to move along a guide post 12. The outer wall of the rotating screws 10 is threadedly fitted with the push plate 2. The inner wall of the push plate 2 is slidably connected to an injection tube 3 that is engaged with the outer wall of the body 1. The outer wall of the injection tube 3 has a scale. The outer wall of the injection tube 3 is fixedly connected to a circular plate 4 that is engaged with the inner wall of the body 1. The outer wall of the body 1 is slidably connected to two mirror-distributed circular sleeves 6 that are slidably connected to the outer wall of the circular plate 4. The circular sleeves 6 are used to fix the position of the injection tube 3. The outer wall of the circular sleeves 6 is provided with a protruding plate. The outer wall of the body 1 is provided with a fitting groove to facilitate the sliding connection of the outer wall of the injection tube 3.
[0028] The inner wall of the machine body 1 is provided with a mounting groove to facilitate the sliding of the rotating lead screw 10. A drive motor is fixedly connected to the inner wall of the mounting groove. A rotating shaft 7 is fixedly connected to the output end of the drive motor. Two evenly distributed active bevel gears 8 are fixedly connected to the outer wall of the rotating shaft 7. The active bevel gears 8 are used to drive the driven bevel gear 9 to rotate.
[0029] The outer wall of the active bevel gear 8 is meshed with a driven bevel gear 9 which is fixedly connected to the outer wall of the rotating screw 10. The driven bevel gear 9 is used to drive the rotating screw 10 to rotate. The inner wall of the body 1 is fixedly connected with a plurality of evenly distributed guide posts 12 which are slidably connected to the inner wall of the push plate 2. The inner wall of the injection tube 3 is slidably connected with a push rod 5 which is slidably connected to the outer wall of the push plate 2. The push rod 5 is used to push the drug.
[0030] During use, the drive motor in the mounting groove on the inner wall of the machine body 1 is started. The drive motor is a stepper motor to achieve high-precision drug delivery. The rotating shaft 7 at the output end of the drive motor starts to rotate, driving the two active bevel gears 8 fixed on its outer wall to rotate synchronously. The active bevel gears 8 and the driven bevel gears 9 on the outer wall of the rotating screw 10 mesh with each other. The rotation of the active bevel gears 8 drives the driven bevel gears 9 to rotate, which in turn drives the rotating screw 10 to rotate in the mounting groove.
[0031] When the screw 10 rotates, the push plate 2, which is threadedly connected to it, moves horizontally along the guide post 12 under the limiting action of the guide post 12. Since the push plate 2 is slidably connected to the push rod 5 on the inner wall of the injection tube 3, the movement of the push plate 2 pushes the push rod 5, thereby pushing out the gel in the injection tube 3. This avoids the use of sensors that are easily affected by external environmental interference, reduces drug administration errors caused by factors such as unstable signals and interference, and can accurately control the moving distance of the push plate 2, thereby accurately controlling the amount of gel extruded, and achieving a stable and accurate drug administration effect.
[0032] Example 2
[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the outer wall of the body 1 is provided with a movable groove that facilitates the sliding connection of the circular plate 4. The inner wall of the movable groove is slidably connected to an extrusion plate 11 that is slidably connected to the outer wall of the circular plate 4. The outer wall of the extrusion plate 11 is fixedly connected to an anti-slip pad 13 that is slidably connected to the outer wall of the circular plate 4. The anti-slip pad 13 is made of rubber and has particles on its surface to increase friction.
[0034] Two evenly distributed compression springs 14 are connected between the outer wall of the compression plate 11 and the inner wall of the moving groove. The compression springs 14 are used to push the compression plate 11. An operation panel is fixedly connected to the top of the machine body 1. Two magnetic blocks 15 that are distributed in a mirror image are fixedly connected to the outer wall of the machine body 1.
[0035] The inner wall of the body 1 is provided with an arc-shaped groove that facilitates the sliding connection of the outer wall of the sleeve 6. Sliding blocks 16 are fixedly connected to both sides of the outer wall of the sleeve 6. The inner wall of the arc-shaped groove is provided with a limiting groove that facilitates the sliding of the outer wall of the sliding block 16. A magnetic sheet 17 that fits against the outer wall of the magnetic block 15 is fixedly connected to the outer wall of the sleeve 6. The magnetic sheet 17 is used to fit against the magnetic block 15.
[0036] During use, when installing the injection tube 3, align the circular plate 4 on the outer wall of the injection tube 3 with the moving groove on the outer wall of the machine body 1 and insert it. During insertion, the circular plate 4 contacts the trapezoidal inclined surface of the extrusion plate 11. As the circular plate 4 goes deeper, the extrusion plate 11 is squeezed and compresses the extrusion spring 14 to move backward. When the circular plate 4 is fully inserted into the moving groove, the extrusion spring 14 returns to its original shape and pushes the extrusion plate 11 forward, so that the anti-slip pad 13 on the outer wall of the extrusion plate 11 fits tightly against the outer wall of the circular plate 4, and the injection tube 3 is initially fixed by friction.
[0037] At the same time, the protruding plate on the outer wall of the sleeve 6 is pushed to move along the arc groove, and the sliding block 16 on the outer wall of the sleeve 6 slides in the limiting groove to ensure the stability of the rotation of the sleeve 6. When the sleeve 6 rotates to a certain angle, the magnetic plate 17 on the outer wall of the sleeve 6 and the magnetic block 15 on the outer wall of the body 1 attract each other and stick together, and the sleeve 6 is further fixed by magnetic force. At this time, the injection tube 3 is sleeved on the inner wall of the sleeve 6, and the installation of the injection tube 3 is completed. This multiple fixing method not only ensures the convenience of the installation of the injection tube 3, but also ensures its stability during use, and prevents the injection tube 3 from loosening or shifting during drug administration. The operation is now complete.
[0038] The remaining structure is the same as that in Example 1.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
