Technical Field

The present invention relates to an iontophoresis device, and more particularly, to a lightweight iontophoresis device using individual activation electrodes.

Background

Various iontophoresis devices are commercially available to improve the use of cosmetics or medical treatments by using electric power. For example, chinese patent application No. 200951261Y discloses a mask having a conductive mesh and an electrode patch. When the current of positive and negative ions is released, the positive and negative ions generated by the current are distributed on the conductive mesh layer of the ionic facial mask, and the active ingredients on the cosmetic facial mask are introduced into the skin through the ions which alternately run.

PCT patent WO2016016015a1 provides another embodiment, a support member for a mask comprising electrodes and a counter separated by an insulating zone. However, the current cannot be appropriately adjusted according to a specific skin region by the existing iontophoresis device, and thus a new device is required to realize a function of appropriately adjusting the current according to the specific skin region.

Detailed Description

Fig. 1 is a schematic view of a lightweight iontophoretic device 10 for the medical or cosmetic treatment of the skin. Iontophoresis device 10 is a mask in this embodiment, but iontophoresis device 10 can be any shape and can be used in any area of the body where treatment is desired. Iontophoresis device 10 includes support layer 20, electrode layer 30, control module 15, return electrode 25, connection cables 26,61, and connector 60. The support layer 20 may include a flexible, non-conductive material such as, but not limited to, a synthetic resin or a polymer. The electrode layer 30 may be bonded to the support layer 20 by gluing or lamination (lamination) techniques, in some embodiments, the electrode layer 30 may also be some conductive pattern made directly on the support layer 20 by printing, coating, sputtering or other patterning techniques.

Fig. 2 is a schematic diagram of the electrode layer 30 of fig. 1 in the embodiment. The electrode layer 30 may include a plurality of insulated electrodes 40. Each electrode 40 may include one or more branches having conductive points 50. Each electrode 40 may include the same or a different number of conductive dots 50. The number and location of the conductive dots 50 on each electrode 40 may be of different designs, and in some embodiments the number and location of the conductive dots 50 may depend on the underlying skin, muscle groups, acupoints, and/or other conditions. In other embodiments, one or more of the electrodes 40 may not require the conductive dots 50. Depending on the electrode pattern design, the electrodes 40 can apply ion introduction therapy directly to the face or other parts of the body.

Each electrode 40 is connected to control module 15 via connector 60 and cable 61, and control module 15 is electrically coupled to return electrode 25 via cable 26. The return electrode 25 is attached to other parts of the body, i.e. to parts that are not contacted by the iontophoretic device 10. The purpose of return electrode 25 is to complete the entire circuit from control module 15, via electrode 40, to conductive point 50, then through the body to return electrode 25, and finally back to control module 15.

The control module 15 is used to connect the electrode 40 with a voltage source or a current source. Each electrode 40 may or may not be connected to a power source for the purpose of performing medical or cosmetic iontophoresis therapy on only selected portions of the face or body. For example, as shown in fig. 2, when only the forehead portion requires treatment, only the rightmost electrode 40 (and attached conductive spot 50) may be energized. Any number of electrodes 40 may be energized at any particular time. Studies have shown, however, that turning on (energizing) one or a certain number of electrodes 40 at a time makes the therapy more effective, as this allows more flexibility in adjusting the current or voltage.

Regardless of the location of the iontophoresis device 10 on the body, the total impedance of the circuit may vary from electrode 40 to electrode due to a number of factors including skin moisture, the length of the circuit between the conductive site 50 and the return electrode 25. For example, the circuit impedance through the conductive dot 50 of the mark a is different from the circuit impedance through the conductive dot 50 of the mark B.

If all electrodes 40 are turned on simultaneously, the different impedances can make it difficult for the current to be accurately controlled, and some skin areas will receive more current than others, resulting in uneven treatment. Because the electrodes 40 in the iontophoresis device 10 can be individually turned on and controlled, impedance differences between different electrodes 40 can be compensated for, thereby bringing about a more uniform treatment. In addition, there may be times when only a particular skin region needs treatment or when the length of time that a particular skin region needs treatment is different, and the present device can achieve this by turning on only the electrodes 40 of that particular skin region. In some embodiments, different amounts of current may be applied to different skin regions as desired.

In some embodiments of fig. 3, the control module 15 includes at least one circuit 116 corresponding to each electrode 40, such that each electrode 40 can be individually turned on.

FIG. 4 is a schematic diagram of the circuit 117 of the control module 15 of FIG. 1 using the variable current source 1171 and/or the variable current source 1175 according to another embodiment. The variable current source 1171 is coupled between a power source and a first terminal of a fifth switch 1172, a second terminal of the fifth switch 1172 is coupled to a node 1173, the node 1173 is coupled to the one or more electrodes 40 through a cable 61 and a connector 60, a second terminal of the fifth switch 1172 is coupled to a first terminal of a sixth switch 1174, and a second terminal of the sixth switch 1174 is coupled to ground.

The circuit 117 may be connected to the return electrode 25 via a cable 26 and may include a variable current source 1175. The variable current source 1175 is coupled between a power source and a first terminal of the seventh switch 1176. A second terminal of the seventh switch 1176 is coupled to the node 1177, and the node 1177 is coupled to the cable 26. A second terminal of the seventh switch 1176 is further coupled to a first terminal of the eighth switch 1178, and a second terminal of the eighth switch 1178 is grounded.

In some embodiments of fig. 4, the control module 15 includes at least one circuit 117 corresponding to each electrode 40, so that each electrode 40 can be conducted separately.

In summary, the present invention provides a lightweight iontophoresis device that can be used to apply medical cosmetic treatments directly to the skin. The iontophoresis device may include an electrode layer having a plurality of individually conductive and insulated electrodes, each electrode including one or more branches having conductive points. The control module is used for independently connecting each electrode with a voltage or current source, and can provide medical cosmetic iontophoresis therapy for specific parts of the face or the body, thereby providing more effective treatment effect. The device can flexibly adjust the current or voltage so as to accurately select the current or voltage used when treating a specific skin area. In addition, since only a specific skin area is treated at a specific time, the current or voltage required is small, which may give a more pleasant experience to the user.
