Description

Technical Field

[0001] This utility model relates to the field of electroosmotic drug delivery technology, specifically to an electrode mechanism and an electroosmotic drug delivery device. Background Technology

[0002] Electroosmotic drug delivery is a drug administration method based on the principle of iontophoresis. It involves bringing a drug-containing gel into contact with the skin (dermis and mucous membranes) and applying an electric current, causing drug ions to migrate and be introduced into the skin or into the body via the skin. Electroosmotic drug delivery technology is widely used in various fields such as medicine and aesthetics due to its non-invasive nature and high drug delivery efficiency.

[0003] Existing electroosmotic drug delivery electrodes typically consist of at least two electrodes. When connecting the gel to the electrodes, the electrodes are often directly pasted or placed on the surface of the gel. Although this connection method is simple, considering the uniformity of the electric field, the installation positions of the two electrodes need to be calculated separately before pasting or placing them on the surface of the gel, which is a cumbersome operation.

An electrode is provided in each mounting slot. An electrode channel is formed between the two mounting slots.

[0006] The two mounting slots and the base layer sidewall respectively form a first connecting channel and a second connecting channel, and the first connecting channel and the second connecting channel are respectively provided with wires connected to the corresponding electrodes.

[0007] Preferably, the cross-sectional shape of the base layer perpendicular to the depth direction is circular, one mounting groove is integrally formed as a cylinder, and the other mounting groove is integrally formed as an annular column.

[0009] Preferably, the cross-sectional shape of the base layer perpendicular to the depth direction is polygonal, one mounting groove is integrally formed as a polygonal column, and the other mounting groove is integrally formed as a ring-shaped column with a polygonal cross-section.

[0010] Preferably, the bottom of the electrode has multiple contact points that extend downward into the gel.

[0011] Preferably, the contact point is formed by gradually narrowing from top to bottom at the connection point with the electrode.

[0027] Example 1

[0028] Please see Figure 1-4 This embodiment provides an electrode mechanism, which includes an electrode layer 100 disposed at the top of a gel. The electrode layer 100 includes a base layer 210. A downward-opening groove 220 is formed on the side of the base layer 210 corresponding to the gel. A barrier portion 230 is formed in the groove 220. The barrier portion 230 is an annular body formed by the inward reduction of the sidewall of the groove 220. The barrier portion 230 is used to divide the groove 220 into two mounting slots 240 with the same area. An electrode is provided in each mounting slot 240. An electrode channel is formed between the two mounting slots 240.

[0029] A first connecting channel 310 and a second connecting channel 320 are respectively formed between the two mounting grooves 240 and the side wall of the base layer 210. The first connecting channel 310 and the second connecting channel 320 are respectively provided with wires connected to the corresponding electrodes.

[0030] This invention integrates two or more electrodes into one unit, making it suitable for gels of different shapes and sizes. It also eliminates the need for position calculations before pasting or placing, resulting in simple and quick installation and improved installation efficiency.

[0031] In this embodiment, the cross-sectional shape of the base layer 210 perpendicular to the depth direction is circular, one mounting groove 240 is generally cylindrical, and the other mounting groove 240 is generally annular cylindrical.

[0032] In this embodiment, the cross-sectional shape of the base layer 210 perpendicular to the depth direction is annular, and the two mounting grooves 240 are both constructed as annular columns.

[0033] In this embodiment, the cross-sectional shape of the base layer 210 perpendicular to the depth direction is polygonal, one mounting groove 240 is generally formed as a polygonal column, and the other mounting groove 240 is generally formed as a ring-shaped column with a polygonal cross-section.

[0034] The above structure allows the electrode mechanism to be used for motor installation in accordance with different electric field distribution requirements, and it can also be used for installation on gel bodies of different shapes, greatly improving its applicability.

[0035] In this embodiment, the bottom of the electrode has multiple contact points 250 that extend downward into the gel.

[0036] The above structure allows the electrode to not only contact the gel at the top but also penetrate deep into the gel, increasing the contact area between the electrode and the gel, improving the connection strength between the electrode and the gel, enhancing the contact between the electrode and the drug delivery medium, and helping to transmit the electric field more effectively.

[0037] In this embodiment, the connection point 250 is formed by gradually narrowing from top to bottom at the connection point with the electrode.

[0038] The above structure allows for the selection of the shape of the contact point 250 inserted into the gel body according to requirements, thereby expanding its applicability.

[0039] In this embodiment, the base layer 210 is an insulating material.

[0040] The above structure can insulate the electrodes and prevent interference.

[0041] In fact, the base layer 210 is set as a single unit, eliminating the need for a separate backing layer or other connecting layers to connect the electrodes, thus saving materials.

[0042] In this embodiment, the mounting groove 240 has an opening and a bottom wall. The groove 220 is formed by gradually recessing from the opening outward along the depth direction to the bottom wall. The projection of the opening along the depth direction on the base layer 210 does not exceed the area where the bottom wall is located.

[0043] The above structure can improve the connection strength between the electrode and the mounting groove 240, and prevent the electrode from falling out of the mounting groove 240 when it is squeezed.

[0044] Example 2

[0045] Seen in Figure 4-8 This embodiment provides an electrode mechanism, which differs from Embodiment 1 in that: a plurality of blocking portions 230 are formed in the groove 220, the plurality of blocking portions 230 are used to divide the groove 220 into a plurality of mounting slots 240 with the same area, the number of mounting slots 240 is an even number, and an electrode channel is formed between adjacent mounting slots 240.

[0046] The above structure allows for adjustments to the number of electrodes as needed, and can also be adapted to the shape of the gel, thus improving the device's practicality.
