3 Terminology and units of measurement

3:1 Limited pressure limitedpressure The rated maximum working pressure set by the electric gastric lavage machine, in kilopascals (kPa):

4 Overview

Electric gastric lavage machine (hereinafter referred to as gastric lavage machine) is a kind of medical equipment, suitable for various medical units, emergency centers, etc: Rescue gastric lavage: It is driven by electromagnetic pumps, etc:, through manual and automatic control of the internally set working pressure, flow rate, Fluid flushing volume, fluid absorption volume and other parameters can be used to achieve multiple cycles of sucking out the contents from the stomach and injecting flushing liquid into the stomach operate:

5 Metrological characteristics

5:1 Limiting pressure The absolute value of the limited pressure should be within the range of (57±10)kPa: 5:2 Changes in working pressure The working pressure change of the instrument is ±5kPa, but the maximum absolute value should not be greater than 67kPa: 5:3 Traffic When using oral intubation: it should not be less than 2:0L/min; When using a nasal cannula: it should not be less than 1:0L/min: 5:4 Self-controlled flushing volume and self-controlled suction volume For gastric lavage machines with automatic control, the volume of self-controlled flushing should not exceed 350mL/time, and the volume of self-controlled suction should not be large: At 450mL/time, the amount of self-controlled liquid absorption should be greater than the amount of self-controlled flushing, but not greater than 150mL/time: Note: The above terms are not used as the basis for judging eligibility, but are for reference only:
