An apparatus and method for inactivating infectious organisms in human body are provided. The apparatus comprises a body having an elongated balloon shape with an open end; a disinfectant containing chlorine dioxide accepted in the body; and an activation module coupled to the body, the activation module includes a case having an opening capable of accommodating the body, an energy supply unit for supplying energy to the disinfectant to activate the chlorine dioxide and a controller for controlling the energy supply unit. The method comprises the steps of inserting the device into a vagina and controlling a degree of activation of the chlorine dioxide to inactive infectious organisms in the vagina by adjusting an intensity of the energy.

A pump device, a respiratory device and a method for providing a respiratory gas. A specially formed rotor and a corresponding pump chamber are used so that an approximately sinusoidal flow of an out-flowing fluid is possible. With the combination of two pump chambers with rotors driven in a 180° phase-shifted manner to one another, an almost constant flow can be created at a common outlet. In addition, the system is designed to be highly dynamic with simultaneously relatively low energy consumption.

A gas mixture apparatus includes a measurement control system, an activation system, a pressurized chamber with one or more gases, and a mixing chamber. A filter can be preattached to an outlet of the mixture apparatus, allowing excess gas to be discharged therethrough and then atmospheric air to be drawn into the mixture apparatus through the filter for creating a therapeutic gas mixture.

Embodiments of the present invention provide a device and a method for treating at least one of hypertension, pulmonary arteries, diabetes, obesity, heart failure, end-stage renal disease, digestive disease, urological disease, cancers, tumors, pain, asthma or chronic obstructive pulmonary disease by delivering an effective amount of a formulation to a tissue. In embodiments of the present invention, the formulation may include at least one of a gas, a vapor, a liquid, a solution, an emulsion, or a suspensions of one or more ingredients. In embodiments of the present invention, amounts of the formulation and/or energy are effective to injure or damage tissue, nerves, and nerve endings in order to relieve disease symptoms.

Devices, and methods for generating variable inhalable products (e.g., variable density, phase, and size products) are provided. Methods for treating or preventing a disorder in a subject using variable products generated by the devices are also provided herein. Additionally, inhalers and breathing systems comprising the devices are provided.

A mixed gas generating system with oxygen generator or breathing tube includes a hydrogen generator and an oxygen generator or a breathing tube. The hydrogen generator is configured to generate a hydrogen gas by electrolyzing water. The oxygen generator is configured to generate a first oxygen gas. The breathing tube is configured to receive a first oxygen gas from an oxygen supplying device. The hydrogen gas generated by the hydrogen generator is mixed with the first oxygen gas generated by the oxygen generator or provided by the breathing tube through a gas mixing tube or outputting the first oxygen gas to the hydrogen generator, so as to form a mixing gas for the user to inhale.

A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.

In accordance with various embodiments of the disclosed subject matter, an anti-choking apparatus is provided comprising a substantially hollow body comprising a first large cross section body region connected to a second large cross section body region via a small cross section body region; a plurality of auxiliary tubes coupled at respective first ends to respective portions of the body between the first large cross section body region and the small cross section body region, each of the auxiliary tubes having second ends with fans mounted thereat and configured to urge air through the auxiliary tubes and substantially hollow body; and a mouth tube couped at a first end to the small cross section body region and having a second end configured for insertion into an airway of a choking victim; wherein an airflow through the small cross section body region induces a pressure gradient within the mouth tube such that a reduced air pressure at the second end of the mouth tube exerts a force upon an obstruction within the airway.
