Abstract: Provided are an anesthesia respiration apparatus, an anesthesia respiration gas path system, and an anesthetic gas path system, to exhibit a novel anesthesia respiration structure. In this structure, some channels are provided in an anesthesia main machine, and no long external pipeline or only a small number of long pipelines are required to meet demands of gas path connection, thereby reducing various potential safety hazards and inconvenience caused by excessive exposed long pipelines.

Abstract: An injection pump and an infusion pump are provided. Display areas of screen assemblies of the injection pump and the infusion pump extend from the left sides of the center lines of the front sides of pump doors to the right sides of the center lines. Widths of the display of the screen assemblies of screen assemblies are greater than the heights thereof. Or the widths of the screen assemblies of the screen assemblies are greater than or equal to 70% of the widths of the front sides of the pump doors. By using the modes above, the screen assembly may form a roughly elongate display area. At least part of the display area also possesses a touch function, so that some physical buttons used for inputting instructions can be omitted, ensuring that the display area is larger, presentation of more information is displayed, and viewing of users is facilitated.
