Compact type mixed gas breathing medical device using hydrogen as effective constituent

Abstract

The invention discloses a compact type mixed gas breathing medical device using hydrogen as an effective constituent. The device comprises a reactor and a mixing cavity. Solid metal hydride is filled in the reactor which is provided with a heat transferring medium return circuit. A gas outlet of the reactor is communicated with a hydrogen inlet of the mixing cavity through a pipeline. A valve is arranged on the pipeline between the gas outlet and the hydrogen inlet. The mixing cavity is further provided with a gas inlet and at least one gas outlet. Due to the fact that the reactor is provided, and the solid metal hydride arranged in the reactor is heated or cooled by the heat transferring medium return circuit, and the control of flow and concentration of the hydrogen prepared by the reactor is achieved. Meanwhile, the valve is arranged on the pipeline and used for controlling a switch of hydrogen supply. Further more, the hydrogen inlet of the mixing cavity and the gas inlets enable the hydrogen to be intensively mixed with other mixed gas in the mixing cavity, and therefore multicomponent mixed gas with therapeutical effect can be made continuously, safely and reliably by combining with the reactor, wherein the effective constituent of the multicomponent mixed gas is hydrogen.

Description

technical field [0001] The invention belongs to clinical auxiliary treatment equipment, and relates to a gas breathing medical device, in particular to a compact mixed gas breathing medical device with hydrogen as an active ingredient. Background technique [0002] As we all know, oxygen therapy has now become an important routine treatment method, and various types of oxygen supply technologies have also become very mature and have reached a high level of marketization; on the contrary, research on the clinical effects of other types of gases has started Later, reports on corresponding medical gas supply solutions are even rarer. [0003] Recent medical research shows (Zhang Wei, Cai Jianmei, Kang Zhimin, Sun Xuejun. Advances in Hydrogen Molecular Medicine Research. Journal of Second Military Medical University, 2009,30(10):1203-1205), hydrogen molecules have a weak reducing effect and are selective Strong, non-toxic and non-residual, it is an ideal antioxidant substance f...

Problems solved by technology

[0004] As mentioned above, the current ways of giving hydrogen mainly include breathing gaseous hydrogen and taking (or injecting) hydrogen solution. Although the input process of the latter is safe and reliable, it is difficult to produce on a large scale, and the hydrogen molecules are small and easy to store during storage. Escaping from the solution leads to leakage, causing safety hazards and reducing the therapeutic effect of the solution; moreover, hydrogen cannot be directly separated from the air like oxygen, because it is difficult to ensure low leakage during long-term storage , so it cannot meet the needs of clinical applications; at the same time, hydrogen is flammable and explosive, and it is difficult to guarantee the safety of hydrogen in the process of mixing with other gases (especially air or pure oxygen)
