Description

TECHNICAL FIELD

[0001] The utility model relates to oxygen bottle auxiliary card technical field, concretely is oxygen residual amount monitoring and prompting device. BACKGROUND

[0002] The traditional oxygen cylinder indicator can only display "empty" and "full" states, and cannot quickly identify the remaining oxygen amount and oxygen supply time. During patient in-hospital transfer handover, although a 4L small oxygen cylinder with larger oxygen capacity and more accurate flow rate is used, medical staff still cannot obtain the remaining oxygen information in the first time. Because the oxygen flow rate of patients is different, the available use time of the oxygen cylinder is also different, and medical staff need to rely on complex and difficult-to-remember conversion tables for calculation, which not only consumes time and effort, but also increases the risk of calculation errors and insufficient oxygen supply in emergency situations.

[0003] For example, the Chinese authorized patent "oxygen time conversion card capable of identifying oxygen residual amount" with publication number CN218512859U includes a fixed disc, a fixed block, a first turntable, and a second turntable. The end of the knob lever extending into the fixed disc is fixed with three sets of limiting blocks, and the end of the knob lever extending into the fixed disc is fixedly connected with a connecting spring. The oxygen time conversion card capable of identifying oxygen residual amount is provided with a knob lever. By rotating the knob lever, the knob lever will drive the first turntable and the second turntable to rotate, so that the first turntable and the second turntable are synchronously rotated. By pulling the knob lever to rotate, one set of limiting blocks will be separated from the limiting groove in the first turntable, so as to conveniently drive the second turntable to rotate, and another set will extend into the interior of the first turntable.

[0004] The above-mentioned prior art is used for prompting the residual amount of the oxygen cylinder, but due to the different corresponding flow rates of the oxygen cylinder under different pressures, it is difficult to intuitively understand the residual amount of the oxygen cylinder in actual work, thereby causing inconvenience to the staff, and therefore it does not meet the existing needs.
