This document provides methods and materials for treating hypocapnia. For example, methods and materials for delivering CO.sub.2 to a mammal to treat hypocapnia or compensate for a reduced level of CO.sub.2 are provided.

Fluid delivery and measurement systems and methods are disclosed.

A gas vending system for health application, comprising: a healthy gas generator module, a control module, and a charging/payment module. The healthy gas generator module is used to generate a healthy gas. The control module is connected to the healthy gas generator module for monitoring the usage state of the healthy gas and generating a volume consumption signal for the healthy gas. The charging/payment module is connected to the control module for receiving the volume consumption signal for the healthy gas and then generating a toll after computing. The charging/payment module is adapted to accept cash or charging a debit card or credit card according to the toll.

A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber. When the valve is actuated, the aqueous solution flows from the reservoir through the internal chamber and into the reaction chamber. This flow washes the catalyst into the reaction chamber along with the aqueous solution. The solution and catalyst mix with the peroxide adduct and cause an oxygen-generating reaction.

Embodiments relate to systems and methods for therapeutic gas delivery for personal medical consumption. A hydrogen delivery system herein can include one or more electrolytic cores which use source water to carry out electrolysis-based reactions, and obtain free hydrogen (H2) gas which can be separated using a proton exchange membrane (PEM) or other filter for collection and delivery to a user. In aspects, the electrolytic core or cores can be constructed or scaled to produce a sufficient amount of hydrogen (H2) gas so that the user can ingest that gas directly, immediately, and/or in real-time or near real-time, without a need for storage of the gas. In aspects, the system can be portable, and configured with a vent port to eliminate oxygen (O2) gas that may accumulate during electrolytic reactions, and also a coalescer unit to reduce or eliminate water or water vapor from the output hydrogen (H2) gas.

The present disclosure relates to a medicament delivery device comprising a medicament receiving element, at least one fluid chamber having a fluid outlet configured to direct fluid vapour towards the medicament receiving element, a heating element for heating the fluid in the at least one fluid chamber. The device is configured such that, in use, the heating element heats the fluid in the at least one fluid chamber to at least partially evaporate the fluid so that the vapor pressure in the at least one fluid chamber increases until the fluid is expelled out of the at least one fluid chamber through the fluid outlet towards the medicament receiving element and entrains the medicament towards the patient's skin.

Embodiments of the invention provide swallowable devices, preparations, and methods for delivering drugs and other therapeutic agents within the GI tract. Particular embodiments provide a swallowable device such as a capsule for delivering drugs or other therapeutic agents (TA) into a wall of the GI tract such as the stomach or small intestine. The swallowable device comprises a sensor, a combustible propellant (CP) and a therapeutic agent preparation (TAP) comprising at least one TA. The sensor triggers the CP to ignite and propel the TAP into the wall of the GI tract in response to an external condition or change in external condition. Embodiments of the invention are particularly useful for orally delivering drugs or other TAs which are degraded within the GI tract and require parenteral injection.

An anti-explosion gas generator for health use is provided. The anti-explosion gas generator for health use includes an electrolysis device for electrolyzing water to produce a gas mixture of hydrogen and oxygen. The gas generator for health use further includes a gas mixing system coupled to the electrolysis device for receiving the gas mixture. The gas mixing system mixes the gas mixture with water vapor, an atomized medicine, a volatile essential oil or a combination thereof to produce a health gas. The health gas is provided for being inhaled by a user.

Method of generating an aerosol by means of an inhalation device for inhalation by a human or animal body, the method comprising providing liquid in the inhalation device, chemically generating gas bubbles in the liquid, bursting of the gas bubbles at the surface of the liquid, thereby generating an aerosol.
