Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an ultrasonic conductivity coupling electrode patch. Background Art

[0002] Ultrasound-targeted transdermal drug delivery technology is the third major route of drug delivery after oral and parenteral administration. Physical methods such as ultrasound and electric pulses are important means of promoting transdermal drug penetration. For drugs to successfully penetrate the skin and deliver their therapeutic effects, the first step is to overcome the skin barrier and increase the permeability of the skin and tissue to the drug. Then, kinetic energy must be applied to the drug, causing it to move in the direction of energy transmission. To date, nearly all methods studied to enhance transdermal drug penetration, including chemical, physical, biological, and pharmaceutical methods, have focused on reducing or eliminating the barrier effects of the stratum corneum and increasing the kinetic energy required for drug entry.

[0003] Ultrasound and electric pulses are physical penetration enhancement methods that have been widely studied in recent years. Using ultrasound and electric pulses alone or in combination, they produce phonophoresis, electroporation, and iontophoresis. Ultrasound and electric field energy, applied in a specific manner to the skin, penetrates the stratum corneum, creating dense microscopic cracks that allow drug molecules to pass through, a process known as pore formation.

[0004] In Chinese invention patent application number 2009103032253, Weng Chunxiao disclosed a device for transdermal drug delivery (electroconophoresis, EPP) using superimposed ultrasound and electric fields. A Chinese patent application number 921060947 describes a device that synchronizes the output of ultrasound and medium-frequency electricity for transdermal drug delivery. The drug delivery function of these instruments and devices relies on a specially designed application system (treatment head or electrode) that is applied to the human body. This specialized application system achieves multiple energy outputs, drug loading and release, as well as fixation and isolation, ensuring smooth drug delivery. However, the aforementioned patents do not disclose the detailed structure of the application system.

[0005] In patent application number 002415259, Weng Chunxiao disclosed a treatment tip for an ultrasonic conductance transdermal drug delivery device. Furthermore, in patent application number 942485904, he disclosed a transdermal drug delivery patch with electrodes. The implementation of these two patents enables the combined effects of ultrasound and electric field iontophoresis to promote transdermal drug delivery.

[0006] There are a series of ultrasonic conductivity transdermal drug delivery system products on the market, such as ultrasonic conductivity meters and ultrasonic conductivity coupling electrode patch series products. In the past 20 years, according to market feedback and demand at different stages, the connection method between the output end treatment head of the ultrasonic transdermal drug delivery device and the disposable special consumable ultrasonic conductivity coupling electrode patch has been innovatively improved many times, including the original first-generation adhesive connection method, the second-generation mechanical positioning structure connection method ("Composite electrode of ultrasonic conductivity transdermal drug delivery device with positioning structure" utility model patent certificate number 1448418), the third-generation magnetic adsorption connection mode ("An ultrasonic transdermal drug delivery device with magnetic therapy electrode"). Conductivity meter" utility model patent certificate number 5052521), due to multiple innovations and changes, the current ultrasonic transdermal drug delivery devices (ultrasonic conductivity meter series) used on the market have multiple connection methods between the output end treatment head and the disposable special consumables (ultrasonic conductivity coupling electrode patch). All of them are in use, but the simultaneous existence of multiple modes requires customers to purchase multiple mode output treatment head accessories and disposable special consumables (ultrasonic conductivity coupling electrode patch) to match them. Improper management will also affect the normal treatment of patients and bring inconvenience and high costs to the procurement management, production management, and market management of manufacturers.
