By a waterproof bag of the present invention comprising an insulator electrode film or an insulator electrode sheet for low-frequency electric stimulation having an electrostatic capacitance of 0.36 nF/cm.sup.2 or greater, a cordless low-frequency electric stimulation device to which an energization permission sensor function and an underwater communication function are added can be used even in water or when bathing. A low-frequency electric stimulation device having a wireless charging function, an energization permission sensor function, an underwater communication function and the like is configured to have a waterproof structure, thereby implementing a waterproof-type low-frequency electric stimulation device. By dispersing fine particles of an inorganic oxide having a large relative permittivity by 10 to 70 vol % in a resin, a flexible insulator electrode film and an insulator electrode for low-frequency electric stimulation are implemented.

An electro-therapy device that generates a mixed electrical signal through electrodes, wherein the mixed electrical signal is a combination of at least two different frequencies, a first frequency having a first minimum and maximum microamp range and a second frequency having a different second minimum and maximum microamp range. The higher of the two frequencies is superimposed on the lower frequency, creating a current intensity window as an envelope along a profile of the lower frequency. The mixed electrical signal is automatically applied for a pre-determined period of time, and amplitude and/or duration and/or frequencies is varied according to a pre-set schedule.

Current cancer treatments such as surgery, radiation and chemotherapy have significant side-effects for the patients. New treatments are being developed to reduce these side-effects while giving doctors alternative methods to treat patients. This invention introduces a new method for treatment of malignant tumors including brain cancer, pancreatic cancer, lung cancer, and ovarian cancer. The method uses low-power RF wave to disrupt and kill cancer cells during mitosis resulting in shrinking the size of solid tumors. Direction of polarization of the electric field of the RF wave relative to the axis of division of the cancer cells has an impact on the ability of the RF wave in disrupting mitosis and killing the cancer cells. Since the orientation of the cancer cells in a tumor are random a method is needed to change the orientation of the applied RF wave spatially with time to maximize elimination of the cancer cells.

A delivery system for local drug delivery to a target site of internal body tissue is provided. The delivery system comprises a source electrode adapted to be positioned proximate to a target site of internal body tissue. A counter electrode is in electrical communication with the source electrode, and is configured to cooperate with the source electrode to form a localized electric field proximate to the target site. A reservoir is configured to be disposed such that the reservoir is capable of interacting with the localized electric field. The reservoir is configured to carry a cargo capable of being delivered to the target site when exposed to the localized electric field. Associated methods are also provided.

A multifunctional pillow, which is related to the field of medical healthcare, comprising: a cervical curve standard pillow (1), a control board (2), a magnetic therapy massage bar (11), a heating strip (12), an intermediate-frequency electrotherapy bar (13), an ultrasound therapy head (21), a negative ion generator (22), a music player (23), a health and sleep-aiding mask (24), and a microcontroller (25). The magnetic therapy massage bar (11), the heating strip (12), the intermediate-frequency electrotherapy bar (13) are arranged within the cervical curve standard pillow (1). The negative ion generator (22), the music player (23), and the microcontroller (25) are arranged on the control board (2). The multifunctional pillow relies on a cervical curve standard, effectively restores a distended cervical spine, and allows people to fall asleep as quickly as possible, to relax the head, and to restore physical strength in a quality sleep environment.

A system for delivering energy to an isolated part of a mammalian body includes an electrically powered patch and a self-supporting adhesive film. The patch has a major surface and comprises a matrix of at least one flexible, biocompatible material which is capable of conforming to the isolated body part. The self-supporting adhesive film has a first non-tacky surface arranged and configured for releasable attachment to the patch and a second tacky surface, opposite the first surface, for adhesive attachment to the isolated body part. The releasable attachment between the self-supporting adhesive film and the electrically powered patch has a lower strength than the adhesive attachment between the film and the isolated body part. Thus, during use the electrically powered patch is removable from the self-supporting adhesive film while leaving the self-supporting adhesive film adhered to the isolated body part.

Embodiments herein relate to medical devices and methods for using the same to treat cancerous tumors within a bodily tissue. A medical device system is included having at least one electric field generating circuit configured to generate one or more electric fields; control circuitry in communication with the electric field generating circuit, the control circuitry configured to control delivery of the one or more electric fields from the at least one electric field generating circuit; and two or more electrodes to deliver the electric fields to the site of a cancerous tumor within a patient. At least one electrode can be configured to be implanted. At least one electrode can be configured to be external. The control circuitry can cause the electric field generating circuit to generate one or more electric fields at frequencies selected from a range of between 10 kHz to 1 MHz.

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.

Methods and systems for non-invasive selective control of blood pressure are described. For example, noninvasive stimulation of the auriculotemporal nerve (on the surface of the ear) facilitates a decrease in blood pressure without a corresponding decrease in heart rate or breathing rate, as occurs in stimulation of the cervical vagus and trigeminal nerves. Such a therapy may be particularly beneficial during hypertensive crises or like events where the body naturally decreases heart rate and breathing rate to compensate for an increased blood pressure.

A bioelectrode includes a fitting member (1106) formed by an electrically insulating member fixed on a surface of a garment (1100) that comes in contact with a living body (1000), an electrode part (1101a) formed by a conductive member fixed on a surface of the fitting member (1106) that comes in contact with the living body (1000), a connector (1102a) fixed to the fitting member (1106) and configured to connect a bioelectric signal measurement device, a wiring line (1103a) fixed to the fitting member (1106) and configured to electrically connect the connector (1102a) and the electrode part (1101a), and an electrically-insulating insulating member (1105) configured to cover a portion within the surface of the wiring line (1103a) that comes in contact with the living body (1000).
