Abstract

The invention relates to medical gas cylinder centralized supplying devices, in particular to an automatic medical gas switching over busbar device and a gas switching over device. To solve the technical problems in the prior art, the automatic medical gas switching over busbar device and the gas switching over device which are novel in structure, convenient to use and reliable are provided. The technical problems in the prior art are solved due to the designed automatic medical gas switching over busbar device. A medical gas cylinder of a left loop gas inlet assembly and a medical gas cylinder of a right loop gas inlet assembly can be automatically switched over to be used through the automatic gas switching over device. Various medical gases are provided for all medical gas using places through gas supplying loops.

Description

technical field [0001] The invention relates to a centralized supply device for medical gas cylinders, in particular to an automatic switching medical gas busbar device and a gas switching device. Background technique [0002] The currently used medical gas busbar devices have roughly the same structure. They all use double circuits to supply medical gas. The switching method is not easy to manage by manual switching, and it is switched by electromagnetic valve, and it will not work normally in case of power failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel structure, convenient and reliable automatic switching medical gas busbar device and gas switching device for the problems existing in the prior art. An automatic switching medical gas busbar device, through the gas switching device, realizes the automatic switching and supply of the gas of the medical gas cylinder of the left loop air intake c...
