Embodiment Construction

[0015] figure 1 It is a sectional view of an air intake module installed on the integrated frame 30 . like figure 1 As shown, the body 11 of the intake module 10 is provided with a third air channel 12 , and the third air channel 12 occupies part of the length of the body 11 . The opening 26 of the third air passage is used as an air outlet, and is usually connected with a pressure reducing valve. The third air passage 12 is perpendicular to the two spaced apart first valve core chambers 13 and second valve core chambers 14 . The first spool chamber 13 is movably provided with a first spool 15 , and the second spool chamber 14 is movably provided with a second spool 16 . The first air passage 17 is communicated with the first air inlet 19 from the far end of the first spool chamber 13 relative to the third air passage 12, and the inlet 19 is usually used as an inlet of an alternate gas source; The far end of the second spool chamber 14 relative to the third air passage 12 ...

Abstract

The invention provides a gas inlet conversion device for an anaesthesia machine and the anaesthesia machine comprising the same. The gas inlet conversion device comprises a plurality of split gas inlet modules and an integrated frame, wherein the split gas inlet modules are detachably integrated on the integrated frame; each module provides a gas inlet pipeline of one gas source only; and the modules can be fixed on one integrated plate according to types and sequence matching of different gas sources. Therefore, the processing difficulty and the cost of the modules are reduced; meanwhile, different gas source modules of the anaesthesia machine can be matched at will.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an air intake conversion device for an anesthesia machine, and also relates to an anesthesia machine. Background technique [0002] When the anesthesia machine is working, the gas in the centralized gas source or the backup gas cylinder needs to be delivered to the patient. The so-called centralized gas source refers to a total gas supply source assembled in the hospital, which is transported to the terminals of each ward through pipelines. In order to avoid gas supply failure due to failure of the centralized gas source, hospitals are usually equipped with several backup gas sources in the form of gas cylinders, that is, spare gas cylinders. Therefore, the intake switching device of the anesthesia machine should be able to switch between different gas sources. Additionally, the anesthesia machine may need to be connected to multiple gas sources, such as oxygen, air, and nitrou...
