[0016] By dividing the storage cavity, i.e., the area above the gel, into drug delivery areas, the drug can be accurately delivered to the divided drug delivery areas, thus avoiding the situation where the amount of drug is small at the edge of the gel when the drug is added, resulting in uneven drug delivery.

[0017] Preferably, reinforcing ribs for mounting the electrode layer are fixedly provided between the bottoms of the plurality of separators, and the plurality of reinforcing ribs are arranged at equidistantly decreasing intervals inwardly along the center of the dispersion cavity.

[0018] Through the above structure, the connection strength between the separators is enhanced, thereby improving the stability and rigidity of the entire structure.

[0034] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0035] Example 1 See also Figure 1-9 , this embodiment provides an electroosmotic drug delivery device for supplying drugs to the skin, which includes a device body 100, and the device body 100 includes a drug delivery module 110 and a power supply module 120; The power supply module 120 has a top, a bottom and a side, the drug delivery module 110 is arranged at the bottom of the power supply module 120, and a strap 330 is arranged at the side of the power supply module 120; The medication module 110 and the power supply module 120 are detachably assembled and matched through a locking mechanism 130 provided at the power supply module 120, and the medication module 110 and the power supply module 120 are electrically connected through a coupler interface assembly; The power supply module 120 can be used to drive the medication module 110 to operate. The medication module 110 is used to be laid on the medication area of ​​the patient. The strap 330 is used to cooperate with the patient.

[0036] When the present invention is in use, the drug administration module 110 at the device body 100 is covered on the patient's required drug administration area, and then the device is fixed to the patient's required drug administration area by the strap 330. Compared with the prior art, by setting the drug administration module 110 and the power supply module 120 as independent modular units, the two modules can be easily integrated into a whole, which not only enhances the structural flexibility and maintainability of the device, but also simplifies the user's operation process, making the assembly and disassembly process quick and convenient, avoiding the patient's need to deliver the drug at a designated position during drug delivery, poor flexibility, and wire connection, which is very easy to cause entanglement or pulling, affecting the drug delivery problem.

[0037] The locking mechanism 130 ensures a firm connection between the drug delivery module 110 and the power supply module 120, and effectively prevents accidental separation due to external factors such as patient activity, friction with clothing, etc. during use, thereby ensuring the continuity and stability of the electroosmotic drug delivery process.

[0038] In this embodiment, the power supply module 120 has a first shell, a device cavity 210 is formed in the first shell, a plurality of batteries 220 are arranged in the device cavity 210, and a charging port 410 and an adjustment panel 420 are arranged on the top of the first shell.

[0039] The adjustment panel 420 is used to adjust the parameters of the battery 220, such as voltage, current, etc., to adapt to different treatment needs and patient conditions.

[0040] The multiple batteries 220 configured in the device cavity 210 provide continuous and stable power support for the electroosmotic drug delivery device, while allowing the user to conveniently charge the battery pack 220 through the charging port 410 without removing the power supply module or looking for a specific charging device, thereby improving convenience of use.

[0041] In this embodiment, the locking mechanism 130 includes a connector 310 fixedly arranged at the side wall of the power supply module 120, and a connector seat 320 fixedly arranged at the corresponding side walls of the medication module 110 and the power supply module 120. The connector 310 and the connector seat 320 are snap-connected, and a downwardly opening slide groove 530 is formed at the bottom of the connector 310, and an insertion interface is formed on the inner wall of one side of the connector 310 along the length direction; A slider 610 cooperating with the slide groove 530 is formed at the top of the connecting seat 320, a socket 620 is provided at the top of the slider 610, and an installation cavity 810 connected to the slide groove 530 is provided at the top wall of the slide groove 530, and a locking assembly 540 for limiting the slider 610 is provided in the installation cavity 810.

[0042] Through the snap-fit ​​connection between the connector 310 and the connector base 320, quick connection and separation between the medication module 110 and the power supply module 120 is achieved. At the same time, the slide groove 530 at the bottom of the connector 310 cooperates with the slider 610 at the top of the connector base 320 to provide a stable sliding guide between the medication module 110 and the power supply module 120. At the same time, the locking assembly 540 limits the connector base 320 to ensure stability and reliability after connection, effectively preventing the accidental separation of the two modules during use and ensuring the safe operation of the equipment.

[0043] In this embodiment, the locking assembly 540 includes a sliding plate 820 slidably disposed in the installation cavity 810, the sliding plate 820 is fixedly provided with a latch 830 that cooperates with the plug hole 620 along the axial direction of the installation cavity 810, a spring 840 for pressing the sliding plate 820 downward is fixedly provided between the sliding plate 820 and the installation cavity 810, the latch 830 movably passes through the top of the installation cavity 810, and a pressing member 850 is fixedly provided at one end thereof, and the pressing member 850 covers the top of the connecting member 310; The connecting member 310 and the connecting seat 320 have a first through slot 550 and a second through slot 630 at the top of the side away from the power supply module 120 respectively, and the pressing member 850 has a third through slot 860 corresponding to the first through slot 550, and the third through slot 860, the first through slot 550 and the second through slot 630 are commonly connected with a strap 330.

[0044] Through the above structure, the cooperation between the pin 830 on the sliding plate 820 and the socket 620 realizes a stable connection between the connector 310 and the connecting seat 320. At the same time, the spring 840 arranged between the sliding plate 820 and the mounting cavity 810 provides downward pressure for the pin 830, ensuring that the pin 830 can be firmly locked once inserted into the socket 620 without the need for additional locking steps, thereby simplifying the operation process and improving the accuracy and reliability of the connection.

[0045] In fact, the strap 330 and the connecting piece 310 are fitted together so that when the strap 330 is installed on the patient, the strap 330 drives the pressing piece 850 to be in close contact with the connecting piece 310, thereby preventing the locking assembly 540 from being disengaged from the limit of the connecting seat 320 and becoming loose due to shaking. At the same time, the entire locking and unlocking process is simple to operate.

[0046] Example 2 See Figure 1 This embodiment also provides an electroosmotic drug delivery device for supplying drugs to the skin, which differs from the embodiment 1 in that: the coupler interface assembly includes a coupler male seat 520 and a coupler female seat 440, wherein: A plurality of docking grooves 510 are formed at the power supply module 120 and the drug delivery module 110 and are recessed upward along the thickness direction of the power supply module 120 .

[0047] By setting the rotating engagement groove between the coupler male seat 520 and the coupler female seat 440, the two can form a stable rotating engagement when docked, thereby enhancing the stability of the connection between the medication module 110 and the power supply module 120 when receiving a pulling force in the axial direction. At the same time, the locking mechanism 130 is cooperated to further improve the connection stability between the medication module 110 and the power supply module 120 during use.

When the current generated by the storage battery 220 passes through the circuit, an electric field is generated between the gel body and the patient's skin, promoting the drug molecules to pass through the skin barrier and enter the body.

[0052] In this embodiment, a dispersion chamber 430 opening upward is formed at the top wall of the storage chamber 710, and a plurality of partitions 720 connected to the dispersion chamber 430 are equidistantly arranged along the circumferential outer wall of the dispersion chamber 430.

[0055] Through the above structure, the connection strength between the separators 720 is enhanced, thereby improving the stability and rigidity of the entire structure. At the same time, the reinforcing ribs 730 provide a stable support platform for the installation of the electrode layer 740. Due to the reinforcing effect of the reinforcing ribs, the reinforcing ribs can maintain the stable position of the electrode layer and prevent the electrode layer from shifting or deforming due to factors such as vibration and temperature changes, thereby ensuring the long-term stable operation of the device.

[0056] In this embodiment, a connecting tube 230 is axially provided at the power supply module 120 and passes through the top and bottom of the power supply module 120.
