A respiration promoting apparatus and a method for promoting respiration for coordinately stimulating a phrenic nerve of a patient for activating a diaphragm of the patient by a pulsating field that is produced by interference stimulation principles.

The invention relates to a high voltage source to be coupled to an electrode arrangement for a dielectric barrier discharge plasma treatment. It has a high voltage transformer device including a primary and secondary inductor coupled via a magnetic circuit. A feed circuit including a power capacitor, the power capacitor coupled with the primary inductor and a first controllable conductor in series. A controller is arranged to intermittent switching of the first controllable conductor in on- and off-states; and a second controllable conductor is coupled in parallel to the primary windings; the controller arranged to switch the second controllable conductor to a conducting on-state when the first controllable conductor is in an on-state to short the resonating current in the primary inductor.

The present disclosure is directed to a flexible transcutaneous nerve stimulation device for reducing urinary urgency. The devices described herein are designed to enable proper placement by a user to stimulate the user's tibial nerve, while maintaining user comfort and device functionality during wear.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

Provided is a switched capacitor-based electrical stimulation device which supplies a direct current (DC) power, detects a charging voltage charged in any one of a plurality of capacitors, controls the DC power supplied to a capacitor module to repeat a charging level and a resting level according to a charging pattern when the charging voltage is lower than a target voltage, and outputs an electric current to electrodes which contact a human body based on an output pattern.

Devices and methods for treating dry eye and other ophthalmic conditions are provided. The devices may be configured to be located in a patient's fornix. In one embodiment, a device includes a flexible substrate, an antenna disposed on a first side of the substrate, one or more electronic components disposed on the first side of the substrate, and a first electrode and a second electrode disposed on a second side of the substrate opposite the first side. Each of the first electrode and the second electrode comprises an electrode surface and a plurality of slots in the electrode surface defining a plurality of electrode prongs. The plurality of slots facilitate or promote near-field coupling between a transmitter and the antenna. The one or more electronic components are configured to provide electrical power to the first electrode and the second electrode.

Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a modular defibrillator architecture is described. A base unit provides a fully functional defibrillator. The functionality of the base unit can be supplemented by attaching an interface unit to the base unit or by connecting a smartphone the base unit. Such devices provide connectivity as well as a screen for displaying supplementary graphics and/or videos which are useful to support both emergency and maintenance & monitoring activities. In some embodiments a battery pack may also or alternatively be coupled to the base unit to prolong the unit's shelf life before recharging or replacement of its batteries is required. If necessary the base unit can be powered from a connected external device such as a mobile communication device.

The pain-relieving apparatus has a housing, a stimulating surface, user inputs, and a plurality of ports, such as a battery port and a transcutaneous electrical nerve stimulation (TENS) output connector. The stimulating surface may include a suction ring, vacuum apertures, vibration stimulators, a plate, heat and cold transducer elements, and medicinal holders to provide various approaches for relieving pain. The pain-relieving apparatus may also have a sound speaker for producing nerve stimulating sounds.
