Description

Technical Field

[0001] This utility model relates to the field of diffusion cell technology, and in particular to a detachable diffusion cell for a drug transdermal testing instrument. Background Technology

[0002] In the field of drug development, research on the transdermal absorption performance of drugs is crucial. The transdermal drug testing instrument is a key device that simulates the process of drug penetration through the skin and can provide important data for drug formulation design, prescription optimization and efficacy prediction. As the core component of the transdermal drug testing instrument, the performance of the diffusion cell plays a decisive role in the accuracy and reliability of the test results.

[0003] The detachable diffusion cell for transdermal drug testing is assembled from multiple independent components, including a supply cell and a receiving cell. The supply cell holds the drug formulation to be tested, while the receiving cell collects the drug that has penetrated through a skin model or artificial membrane. Currently, to ensure the accuracy of transdermal drug testing, the diffusion cell requires good sealing. However, the detachable diffusion cell sacrifices ease of disassembly in pursuit of sealing. Existing solutions embed magnetic devices at the docking edges of the supply and receiving cells. These magnetic devices are made of high-performance permanent magnet materials and have strong magnetic attraction, allowing the magnetic devices to fit tightly and form a stable magnetic connection when the cells are docked. However, with increased use, the permanent magnet materials in the magnetic devices will age, and the microstructure inside the material will gradually change, leading to disordered magnetic domain arrangement and gradual decline in magnetic properties. This results in less stable docking and reduces the stability of the device connection. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a detachable diffusion cell for a transdermal drug testing instrument, which aims to improve the problem in the prior art where the permanent magnet material in the magnetic device ages with increasing use, resulting in insufficient stability during docking and reduced stability of the device connection.

[0006] As a further description of the above technical solution:

[0007] The cleaning mechanism includes two fixed columns, the bottom ends of which are fixedly connected to the middle of the rear side of the fixed base. A slider is slidably connected to the outer wall of each fixed column. Rotating columns are rotatably connected to the left and right sides of the front end of the outer wall of each slider. Gears are fixedly connected to the upper and lower ends of the outer walls of the two rotating columns. A fixed plate is fixedly connected to the front bottom of the slider. A motor is fixedly connected to the top of the fixed plate, and the output end of the motor is fixedly connected to the gear on the left side of the bottom. Clamping rings are fixedly connected to the middle of the outer walls of the two rotating columns. Cleaning sponges are fixedly connected to adjacent sides of the clamping rings. A fixed ring is fixedly connected to the rear outer wall of the slider. A threaded column is rotatably connected to the middle of the top of the fixed plate, and the inner wall of the fixed ring is threadedly connected to the outer wall of the threaded column.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the fixed base has mounting grooves on the left and right sides respectively, and handles are fixedly connected to the inner walls of the two mounting grooves respectively.

[0010] As a further description of the above technical solution:

[0011] The base is fixedly connected to four corners at its bottom with support columns, and foot pads are fixedly connected to the bottom of each of the support columns.

[0012] As a further description of the above technical solution:

[0013] The top right side of the fixed base is fixedly connected to a control button, and the top of the inner wall is rotatably connected to a control button.

[0014] As a further description of the above technical solution:

[0015] The top left and right sides of the fixed base are fixedly connected to fixed blocks, and ultraviolet lamps are fixedly connected to adjacent sides of the two fixed blocks.

[0016] As a further description of the above technical solution:

[0017] A sealing cover is provided on the top of the inner wall of the upper receiving pool, and a pull ring is fixedly connected to the top of the outer wall of the sealing cover.

[0018] As a further description of the above technical solution:

[0019] A sampling tube is fixedly connected to the front side of the outer wall of the lower receiving pool, and a sealing cap is provided on the front side of the inner wall of the sampling tube.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, during docking, the threaded block at the bottom of the upper receiving pool mates with the threaded groove 2 of the lower receiving pool to complete the initial connection. The fixing sleeve fitted on the outer wall of the upper receiving pool has an inner wall fixing post 1 that can rotate within the circular plate. With the buffer and auxiliary fixing of the spring, the connection between the upper and lower receiving pools is more stable, enhancing the stability and reliability of the device. During disassembly, first rotate the fixing sleeve to disengage it from the threaded groove 1, and then rotate the upper receiving pool to allow the threaded block to rotate out of the threaded groove 2, thereby achieving separation.

[0022] 2. In this utility model, the bottom left gear is driven by a motor. Because the gears on the two rotating columns mesh with each other, the two rotating columns can rotate synchronously, driving the clamping ring and cleaning sponge to rotate. This allows the clamping ring to effectively hold the lower receiving pool, ensuring the stability of the cleaning operation. At the same time, when the threaded column rotates, the threaded engagement between the fixed ring and the threaded column allows the slider to slide on the second fixed column, driving the clamping ring and cleaning sponge to move up and down. This allows the cleaning sponge to clean the surface of the lower receiving pool from all directions. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a detachable diffusion cell for a transdermal drug testing instrument, comprising a fixed base 1, a lower receiving cell 3 disposed in the middle of the inner wall of the fixed base 1 as a key component for collecting liquid after drug penetration, a threaded groove 4 formed at the top of the lower receiving cell 3, a threaded groove 24 formed at the top of the inner wall of the lower receiving cell 3, a circular plate 5 fixedly connected to the outer wall of the threaded groove 4, and an upper receiving cell 6 disposed at the top of the outer wall of the lower receiving cell 3. Installation or removal of the upper receiving cell 6 from the lower receiving cell 3 can be achieved simply by rotating the upper receiving cell 6, ensuring a tight seal at the connection to prevent leakage of the test solution and affecting the test results. A threaded block 7 is fixedly connected to the bottom of the upper receiving cell 6, the outer wall of the threaded block 7 being threadedly connected to the inner wall of the threaded groove 24, and a fixed sleeve 8 is slidably connected to the bottom of the outer wall of the upper receiving cell 6, which can be installed or removed along with the upper receiving cell 6. The upper receiving pool 6 slides up and down during the unloading action. The inner wall of the fixed sleeve 8 is slidably connected to the left and right sides of the fixed column 9. The inner wall of the fixed column 9 is threadedly connected to the outer wall of the threaded groove 4. The bottom ends of the two fixed columns 9 are rotatably connected to the top of the inner wall of the circular plate 5. The bottom of the outer wall of the two fixed columns 9 is fixedly connected to the spring 10. When the upper receiving pool 6 is installed, the fixed column 9 slides upward in the fixed sleeve 8 and rotates around the circular plate 5. At the same time, the spring 10 connected to the bottom of the outer wall of the fixed column 9 is compressed. The elastic force of the spring 10 provides an additional preload force for the upper receiving pool 6, making the connection between the upper receiving pool 6 and the lower receiving pool 3 more stable and enhancing the structural stability of the entire diffusion pool. The bottom of the rear side of the fixed seat 1 is fixedly connected to the fixed plate 11. The middle of the rear side of the fixed seat 1 is provided with a cleaning mechanism 2, which is used to clean the outer wall of the lower receiving pool 3.

[0032] Specifically, the fixed base 1 serves as the basic support structure, providing a stable foundation for the entire system. The lower receiving pool 3 is located in the middle of the inner wall of the fixed base 1, and its top threaded groove 4 is fixedly connected to the circular plate 5, serving as a drug receiving and initial containment mechanism. The threaded block 7 at the bottom of the upper receiving pool 6 is threadedly connected to the threaded groove 4, achieving a stable connection between the upper receiving pool 6 and the lower receiving pool 3. This threaded connection facilitates the disassembly and installation of both, making it convenient for testing different drugs or for cleaning and maintenance of the equipment. The fixed sleeve 8 at the bottom of the outer wall of the upper receiving pool 6, and the fixed column 9 which is slidably connected to the left and right sides of the inner wall of the fixed sleeve 8, form an auxiliary fixing structure with the circular plate 5. The bottom end of the fixed column 9 is rotatably connected to the top of the inner wall of the circular plate 5, and the bottom of the outer wall is connected to a spring 10. When the upper receiving pool 6 is rotated for installation or disassembly, the fixed column 9 slides within the fixed sleeve 8 and is elastically acted upon by the spring 10, ensuring the stability of the upper receiving pool 6 during rotation and preventing it from detaching or being improperly installed due to accidental rotation, thus ensuring that the transdermal drug testing can be performed accurately and reliably.

[0033] Reference Figure 1 , Figure 2 and Figure 5The cleaning mechanism 2 includes two fixed columns 201, the bottom ends of which are fixedly connected to the rear middle of the fixed base 1. A slider 202 is slidably connected to the outer wall of each fixed column 201, allowing the slider 202 to move up and down on the fixed columns 201. Rotating columns 203 are rotatably connected to the left and right sides of the front end of the outer wall of the slider 202, allowing the rotating columns 203 to rotate around their connection point with the slider 202, thereby driving the gear 204 and the clamping ring 207 to rotate. Gears 204 are fixedly connected to the upper and lower ends of the outer walls of the two rotating columns 203, respectively. The gears 204 are designed for transmission; through the meshing of the gears 204, power is transmitted to the rotating columns 203. A fixed plate 205 is fixedly connected to the bottom front side of the slider 202, and the top of the fixed plate 205 is fixed... A motor 206 is connected, serving as a power source. It is fixed to the front bottom of the slider 202 via a fixing plate 205. Its output end is connected to a gear 204. Starting the motor 206 will drive the gear 204 to rotate, which in turn will drive the rotating column 203 to rotate. The output end of the motor 206 is fixedly connected to the gear 204 on the bottom left side. Clamping rings 207 are fixedly connected to the middle of the outer walls of the two rotating columns 203 respectively. The clamping rings 207 are used to fix the cleaning sponge 208. When the rotating column 203 rotates, it drives the clamping rings 207 and the cleaning sponge 208 to rotate. The cleaning sponge 208 contacts the part that needs to be cleaned, thus achieving the cleaning function. The cleaning sponge 208 is fixedly connected to the adjacent side of the two clamping rings 207. A fixing ring 209 is fixedly connected to the rear side of the outer wall of the slider 202. A threaded column 210 is rotatably connected to the top center of the fixing plate 11. The inner wall of the fixing ring 209 is threadedly connected to the outer wall of the threaded column 210.

[0034] Specifically, the slider 202 can slide on the outer wall of the fixed column 201. Its front end is rotatably connected to the rotating column 203.

The output end of the motor 206 is connected to the gear 204 on the bottom left side to provide power to the rotating column 203. The middle part of the rotating column 203 is fixed with a clamping ring 207. The cleaning sponge 208 on one side of the clamping ring 207 can be used for cleaning. The fixed ring 209 fixed on the rear side of the slider 202 is threadedly connected to the threaded column 210 rotatably connected to the top of the fixed plate 11. Rotating the threaded column 210 can adjust the upper and lower position of the slider 202, thereby adjusting the cleaning position of the cleaning sponge 208. The motor 206 drives the gear 204 and the rotating column 203 to rotate, so that the cleaning sponge 208 can clean the target area.

[0035] Reference Figure 1 , Figure 2 and Figure 4The outer wall of the fixed base 1 has mounting slots 12 on the left and right sides respectively. The inner walls of the two mounting slots 12 are fixedly connected to handles 13. The handles 13 are firmly connected to the fixed base 1 through the mounting slots 12, which facilitates the user to carry, move or operate the entire device. The user can adjust the position of the device by holding the handles 13. The bottom of the fixed base 1 has four support columns 14 fixedly connected to each of the four corners. The bottom of the multiple support columns 14 is fixedly connected to the bottom pads 15. The support columns 14 installed at the bottom of the fixed base 1 provide stable support for the fixed base 1, so that the device can be placed stably on the ground or other flat surfaces. The top right side of the fixed base 1 is fixedly connected to a fixing block 16. The top inner wall of the fixing block 16 is rotatably connected to a control button 17. The fixing block 16 fixed to the top right side of the fixed base 1 is the mounting carrier of the control button 17. The control button 17 is rotatably connected to the top inner wall of the fixing block 16. The user can trigger the corresponding control function by rotating the control button 17.

[0036] Specifically, the mounting slot 12 provides a mounting position for the mounting handle 13, making it convenient for users to move and operate the device. The handle 13 provides a convenient part for users to apply force. The support columns 14 at the four corners of the bottom of the fixed base 1 ensure the stability of the device and enable it to be stably positioned in the working position. The foot pads 15 at the bottom of the support columns 14 increase friction to prevent the device from sliding and also play a role in cushioning and protection. The component fixing block 16 fixed on the top right side of the fixed base 1 provides a mounting position for the control button 17. The control button 17 can rotate, and users can control the device, turn it on and off, by rotating it, making the device more stable and easier to operate during use.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Fixing blocks 18 are fixedly connected to the top left and right sides of the fixing base 1. Ultraviolet lamps 19 are fixedly connected to the adjacent sides of the two fixing blocks 18. Fixing blocks 18 serve to fix the ultraviolet lamps 19 and install them on the top left and right sides of the fixing base 1 to make the position of the ultraviolet lamps 19 stable. A sealing cover 20 is provided on the top of the inner wall of the upper receiving pool 6. A pull ring 21 is fixedly connected to the top of the outer wall of the sealing cover 20. The sealing cover 20 is used to seal the upper receiving pool 6 to prevent the leakage of substances in the upper receiving pool 6 or the entry of external impurities. A sampling tube 22 is fixedly connected to the front side of the outer wall of the lower receiving pool 3. A sealing cover 23 is provided on the front side of the inner wall of the sampling tube 22. The sampling tube 22 is connected to the lower receiving pool 3 and samples are taken out from the lower receiving pool 3 for detection and analysis.

[0038] Specifically, the ultraviolet lamps 19 installed on the top left and right sides of the fixed base 1 via the fixing block 2 18 can emit ultraviolet light to sterilize and disinfect the surrounding environment, ensuring the hygiene of the internal environment of the device. The sealing cover 20 on the top of the inner wall of the upper receiving pool 6 can prevent internal substances from leaking and external impurities from entering. The pull ring 21 makes it convenient for users to operate the sealing cover 20, making it easy to add or remove substances from the upper receiving pool 6. The sampling tube 22 on the front side of the outer wall of the lower receiving pool 3 provides a way to obtain samples from the lower receiving pool 3. The sealing cover 23 ensures the sealing of the sampling tube 22, preventing substance leakage and sample contamination.

[0039] Working principle: During use, the bottom threaded block 7 of the upper receiving pool 6 is threadedly connected to the threaded groove 24 at the top of the inner wall of the lower receiving pool 3, thus achieving the initial connection between the upper receiving pool 6 and the lower receiving pool 3. At the same time, a fixing sleeve 8 is fitted on the bottom of the outer wall of the upper receiving pool 6. The fixing posts 9 on the left and right sides of the inner wall of the fixing sleeve 8 are threadedly connected to the outer wall of the threaded groove 4, and the bottom ends of the two fixing posts 9 are rotatably connected to the top of the inner wall of the circular plate 5. The spring 10 at the bottom of the outer wall of the fixing posts 9 plays a certain role in buffering and auxiliary fixing. The connection between the upper receiving pool 6 and the lower receiving pool 3 is further stabilized by the fixing sleeve 8 and the fixing posts 9. When disassembly is required, first rotate the fixing sleeve 8 to remove it from the threaded groove 4, and then rotate the upper receiving pool 6 so that the threaded block 7 at the bottom of the outer wall of the upper receiving pool 6 rotates out of the threaded groove 24, thereby realizing the disassembly of the entire diffusion pool, the upper receiving pool 6 and the lower receiving pool 3, and facilitating the separation of each component.

[0040] Furthermore, the motor 206 is started, and its output end drives the bottom left gear 204 to rotate. Since the gears 204 on the two rotating columns 203 mesh with each other, the two rotating columns 203 will rotate synchronously, thereby driving the clamping ring 207 and the cleaning sponge 208 to rotate, so that the clamping ring 207 can clamp the lower receiving pool 3. At the same time, the threaded column 210 is rotated. Since the inner wall of the fixing ring 209 is threadedly connected to the outer wall of the threaded column 210, the slider 202 will slide on the outer wall of the two fixing columns 201, thereby driving the clamping ring 207 and the cleaning sponge 208 to move up and down along the direction of the fixing columns 201, so that the cleaning sponge 208 can clean the surface of the lower receiving pool 3 in all directions.

[0041] 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.
