Drug delivery hubs are described herein. The drug delivery hub includes a hub housing, a reservoir, a nebulizer channel, and a gas channel. The hub housing defines a housing volume. The hub housing is configured to directly couple with a mask defining a patient cavity. The reservoir is disposed at least partially within the housing volume. The reservoir includes a reservoir volume configured to dispense a medicament. The nebulizer channel is in fluid communication with the reservoir volume and configured to be in fluid communication with the patient cavity when the hub is coupled with the mask. The gas channel is in fluid communication with the nebulizer channel. The gas channel is configured to direct a gas flow toward the patient cavity through the nebulizer channel, drawing a portion of the medicament from the reservoir through the nebulizer channel with the gas flow toward the patient cavity.

There are provided a gas supply apparatus and a gas supply method that are capable of supplying hydrogen gas of a highly accurate and stable hydrogen gas concentration to a body. A ventilator 100 that supplies oxygen-containing gas and hydrogen gas includes a hydrogen gas delivery unit 8 that delivers the hydrogen gas taken in to outside of the ventilator 100, and a control unit 22 that adjusts an amount of the hydrogen gas taken into the hydrogen gas delivery unit 8. The control unit 22 adjusts the amount of the hydrogen gas taken into the hydrogen gas delivery unit 8 based on a flow rate of the oxygen-containing gas.

An adapter for attachment to a medical application device includes an energy generating device and a distal tip for applying the energy generated to skin tissue. The adapter includes a substantially hollow body with a distal end portion and a proximal end portion. The proximal end portion is sized to mount on the distal tip of the energy generating device; the distal end portion is substantially open. The adapter further includes at least one through port extending from the proximal end portion to the open distal end portion of the adapter.

A blood treatment air purging system and method includes a level detector positioned and arranged to detect a low fluid level in a blood circuit indicating a high amount of air in the blood circuit; a blood pump operable with the blood circuit; a venous patient line of the blood circuit; and at least one blood circuit air vent valve, wherein the system and method are configured or programmed to (i) stop the blood pump, (ii) close the venous patient line, and (iii) open the at least one blood circuit air vent valve to atmosphere or a container when the low fluid level is detected, and (iv) run the blood pump to meter air through the at least one blood circuit air vent valve to atmosphere or the container.

A process and a metered dose inhaler, comprising: an air actuator comprising at least one inlet of liquefied gas (LG), at least one air outlet, at least one first LG-expanding volume and at least one second air-containing volume, the first and second volumes are effectively separated by means of a LG-blocking member; a container with an LG source; said container is in a fluid connection with said LG-expanding volume via the at least one LG inlet; The air actuator is facilitating a metered dose airflow by allowing the expansion of said LG in said at least one LG-expanding volume from its condensed liquid phase to its expanded gas phase. The expansion of said LG facilitates the compression of the air within said at least one air-containing volume, such that a metered dose LG-free air flow is inhalable via at least one air outlet.

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.

Surgical devices and methods described herein reduce the risk of surgical fires for patients receiving supplemental oxygen. Airflow with elevated concentrations of oxygen is drawn away from a surgical field when the tubing is fluidly connected to a suction source. Tubing may be strategically positioned at locations presenting risk of oxygen gas buildup, such as the nasofacial sulcus or bucco-facial sulcus. Apertures are present in the turbine wall to draw airflow away from the surgical field and into the tubing. Various embodiments are contemplated in which the tubing is used with a surgical mask or a surgical drape, and a method of use is provided.

A hydrogen-supplying breathable layer in the present disclosure comprises: a thin layer wrapping a hydrogen-producing formula inside, having an airtight outer side as well as an air-permeable inner side on which a plurality of micro pores are opened and featuring a monolayer or a composite layer; a hydrogen-producing formula wrapped inside the thin layer and not dissipated but absorbing moistures in air or liquid water for generation of hydrogen; hydrogen permeating a plurality of micro pores and released to skin and intra-corporal parts. The hydrogen-producing formula in the hydrogen-supplying breathable layer comprises metal peroxides (metal hydroxides or metal hydrides) and aluminum powders (or silica powders); the breathable layer is applicable to a dressing pack or other sanitary paraphernalia in daily lives for relieving non-bacteria inflammations and promoting health care effects.

A vented chest wound seal for a penetrating chest wound includes a flexible sheet including a top surface and a bottom surface, an adhesive hydrogel layer covering a portion of the bottom surface of the flexible sheet, and a plurality of vent channels. The adhesive hydrogel layer includes an inner perimeter and an outer perimeter, and the outer perimeter forms a continuous perimeter of hydrogel along a bottom surface of the flexible sheet. A plurality of vent channels, each including a first opening to a space inside of the inner perimeter, extend radially outward to an outer terminal end vent to the top surface of the flexible sheet. The outer terminal end is spaced apart from the outer perimeter of the adhesive hydrogel layer towards the central portion of the chamber.
