Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a transdermal electrotherapy and drug-assisted treatment device. Background Technology

[0002] Transcutaneous electrical stimulation (TES) technology currently holds significant clinical research value in treating various types of chronic pain and preventing postoperative complications. Conventional ETS devices typically work by attaching electrode units to corresponding acupoints on the patient, powering on the device, and setting relevant parameters (waveform, frequency, intensity) to output current and stimulate the acupoints. To improve efficacy, current technologies offer several methods combining ETS with medication. A common approach is to directly attach a medicated patch to the electrode unit. During use, the patch contacts the patient's skin, and the current released by the electrode unit is transmitted to the skin through the patch, simultaneously releasing the medication. While this method can promote transdermal drug absorption, the medicated patch can affect the current conduction efficiency, thus impacting the effectiveness of the ETS itself and limiting the synergistic effect of ETS and medication. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a transdermal electro-pharmacy synergistic therapy device that, while ensuring the effectiveness of electrostimulation itself, improves the transdermal absorption rate of drugs, thereby more effectively realizing the synergistic effect of electrostimulation and drugs, improving the synergistic therapeutic effect, and enabling the flexible replacement of different functional drug gels to meet the needs of personalized treatment.

[0004] The present invention includes a main unit and an electro-drug therapy unit electrically connected to the main unit. The electro-drug therapy unit includes an annular adhesive attachment, an annular electrode, a drug carrier tray, and a drug gel sheet. The annular adhesive attachment, the annular electrode, and the drug carrier tray are coaxially arranged. The annular electrode is fixed between the side of the drug carrier tray and the inner side of the annular adhesive attachment. The thickness of the drug carrier tray is less than the thickness of the annular electrode. A cavity for accommodating the drug gel sheet is formed between the inner side of the annular electrode and the surface of the drug carrier tray. When the drug gel sheet is placed in the cavity, the side of the drug gel sheet is in contact with the inner side of the annular electrode in the cavity area.

[0005] Furthermore, the electro-drug therapy unit also includes a heating module disposed in the annular electrode and / or drug carrier plate.

[0006] Furthermore, the heating module is embedded in the annular electrode, and the heating module is annular and coaxially arranged with the annular electrode.

[0007] Furthermore, the heating module includes a thermally conductive material and a heating element. The thermally conductive material is annular and embedded in an annular electrode, and the heating element is embedded in the thermally conductive material.

[0008] Furthermore, the electrotherapy unit also includes a temperature detection module, which is located inside or outside the ring electrode and is used to detect the skin surface temperature.

[0009] Furthermore, the transdermal electro-pharmacy synergistic therapy device also includes a connecting wire, one end of which is connected to the ring electrode, the heating module, and the temperature detection module, and the other end is provided with a plug. The main unit is provided with an interface that matches the plug, and the electro-pharmacy therapy unit is electrically connected to the main unit through the connecting wire.

[0010] Furthermore, the connecting wire has several core wires inside, each of which is shielded. The connecting wire is connected to the ring electrode, the heating module, and the temperature detection module through the corresponding core wires.

[0011] Furthermore, several electro-pharmacy therapy units and connecting lines are provided, with each individual electro-pharmacy therapy unit electrically connected to the main unit via a corresponding connecting line.

[0012] Furthermore, the annular adhesive attachment includes an outer ring body and an adhesive layer detachably disposed at one end of the outer ring body.

[0013] Furthermore, an isolation layer is provided between the inner side of the annular adhesive attachment and the outer side of the annular electrode, as well as between the inner side of the annular electrode and the side of the drug-carrying disk.

[0014] The beneficial effects of this invention are that when the electrotherapy unit is attached to the target acupoint, the annular electrode and the drug gel sheet can simultaneously adhere to the skin of the acupoint. The current can directly stimulate the acupoint through the annular electrode, ensuring the effectiveness of the stimulation itself. A portion of the current can also act along the inner side of the annular electrode in the concave area to the drug gel sheet, triggering an iontophoresis effect and improving the transdermal absorption rate of the drug. This more effectively achieves the synergistic effect of electrostimulation and drug delivery, thereby enhancing the synergistic therapeutic effect. Furthermore, the concave area formed between the inner side of the annular electrode and the surface of the drug-carrying plate facilitates the removal and replacement of the drug gel sheet, allowing for flexible use of different functional drug gel sheets to meet personalized treatment needs.

The main unit 1 is the control part of the treatment device, and the electrotherapy and drug delivery unit 2 is electrically connected to the main unit 1. The electrotherapy and drug delivery unit 2 includes an annular adhesive attachment 21, an annular electrode 22, a drug carrier tray 23, and a drug gel sheet 24. The annular adhesive attachment 21, the annular electrode 22, and the drug carrier tray 23 are coaxially arranged. The annular electrode 22 is fixed between the side of the drug carrier tray 23 and the inner side of the annular adhesive attachment 21. That is, the drug carrier tray 23, the annular electrode 22, and the annular adhesive attachment 21 are arranged sequentially from the inside to the outside, forming an annular layered structure. The thickness of the drug carrier tray 23 is less than the thickness of the annular electrode 22, and there is a height difference between the drug carrier tray 23 and the annular electrode 22, so that a cavity is formed between the inner side of the annular electrode 22 and the surface of the drug carrier tray 23. This cavity is used to accommodate the drug gel sheet 24, and when the drug gel sheet 24 is placed in the cavity, the side of the drug gel sheet 24 is in contact with the inner side of the annular electrode 22 in the cavity area.

[0020] In use, the medicated gel sheet 24 is embedded in the concave cavity, and the electrotherapy unit 2 is attached to the target acupoint with the medicated gel sheet 24 facing the acupoint skin via the annular adhesive attachment 21. The electrotherapy unit 2 is then electrically connected to the main unit 1. Based on the structure of the electrotherapy unit 2 of this invention, when attached to the target acupoint, the annular electrode 22 and the medicated gel sheet 24 can simultaneously adhere to the acupoint skin. Current can directly stimulate the acupoint through the annular electrode 22, ensuring the effectiveness of the stimulation itself. A portion of the current can also act along the inner side of the annular electrode 22 in the concave cavity area to the medicated gel sheet 24, triggering an iontophoresis effect and improving the transdermal absorption rate of the drug. This more effectively achieves the synergistic effect of electrostimulation and drug, thereby enhancing the synergistic therapeutic effect. Furthermore, the concave cavity formed between the inner side of the annular electrode 22 and the surface of the drug carrier plate 23 facilitates the disassembly and replacement of the medicated gel sheet 24, allowing for flexible use of different functional medicated gel sheets 24 to meet personalized treatment needs.

[0033] The electrotherapy unit 2 further includes a temperature detection module, which is disposed inside or outside the annular electrode 22 and located at the bottom of the annular electrode 22, separated from the annular electrode 22 by an insulating layer.
