Latest Patents

One of Hasui's latest inventions is an electrode pad used for iontophoresis treatment. This invention addresses the issue of skin irritation, particularly cumulative skin irritation, caused by the transdermal administration of local anesthetics. The electrode pad is designed to provide relief from puncture pain and is safe for both single and repeated administrations. It consists of a base sheet, an electrode, an adhesive sheet with an opening exposing the electrode, and a medicament reservoir containing a local anesthetic. The design ensures that the inner peripheral surface of the adhesive sheet and the outer surface of the medicament reservoir do not come into contact with human skin, thereby reducing irritation.

Another significant patent is the iontophoresis patch, which features a donor gel and a reference gel that contact an external conductor, such as a patient's skin. This patch includes a donor portion with a gel containing a medical agent, a reference portion with a gel mounted with a current-carrying device, and an electrode film that supplies current to both gels. This innovative design enhances the effectiveness of iontophoresis treatments.
