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, nonalcoholic fatty liver 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.

A surgical evacuation system having dual in-series large and small droplet filters is provided. The surgical evacuation system comprises a pump, a motor operably coupled to the pump, and a flow path fluidically coupled to the pump. the flow path comprises a first fluid filter configured to extract a large droplet in a fluid moving through the flow path and a second fluid filter configured to extract a small droplet in the fluid moving through the flow path. the first fluid filter is coupled in series with the second fluid filter. The first fluid filter is positioned upstream of the second fluid filter. An outlet port of the second fluid filter is coupled to an inlet port of a non-fluid filter.

The present invention provides a composition for prevention and/or improvement of pneumonia. More specifically, the present invention provides a composition for prevention and/or improvement of pneumonia and a symptom associated with pneumonia in a subject, comprising molecular hydrogen as an active ingredient.

The object of the invention is to provide a novel pharmaceutical composition for hypertension therapy that can be applied to a wide range of hypertensive patients.

According to the present disclosure, a gaseous pharmaceutical composition for improving hypertension comprising hydrogen gas is provided. The pharmaceutical composition according to the present disclosure can be used for improvement of a wide range of hypertension including essential hypertension.

Embodiments relates to an advance type of portable hydrogen ventilator, which mainly includes: main body, main battery, function board, electrolytic sheet, electrolytic cell and end cover; wherein the bottom of the main body is provided with a battery, the side is provided with a function key, and the top of the main body is closed by an end cover; one side of the function board is connected with a battery, the other side is connected with an electrolytic sheet, and the function board is provided with a function Key; the electrolytic piece is fixed on the main body and placed in an electrolytic cell; the top of the electrolytic cell is provided with a hydrogen filtering chamber. By fixing the electrolytic sheet on the main body, the utility model is convenient for disassembly and replacement, and the electrolysis process is better controlled through the cooperation of the function key and the function sheet. At the same time, the problem of electrolyte leakage is avoided; the utility model has the advantages of simple structure, high gas production quality, convenient operation and low cost.

A respiratory gas delivery system monitors gas flow over the course of a breath in real time and uses this parameter to simulate, in whole or part, the function of a reference respiratory gas delivery system, in particular structural features, particularly structural components of parts of the reference system, to overcome a structural limitation of the reference system.

A healthy gas generating system for generating healthy gas for inhalation by a user includes an electrolysis device, a gas mixing device, and a backfire barrier. The electrolysis device electrolyzes water to generate a gas with hydrogen. The gas mixing device includes a mixer and a vibrator for mixing the combination gas with an atomized gas to produce the healthy gas. The backfire barrier is configured on the output of the gas mixing device or the gas passage of receiving the combination gas to avoid the backflow of the gas.
