Design and application analysis of transport trolley for adjustable oxygen flow oxygen cylinders
摘要
Abstract
Objective To design an oxygen supply device for use in department of emergency intensive care unit(EICU)and department of critical care medicine during the transfer of critically ill patients,and to evaluate its clinical application effect.Methods Through the scenario-based design approach,opinions were solicited through interviews to design the oxygen transport trolley.The data was recorded by using the form-filling method for 58 medical staff during the process of transporting the portable cart equipped with a gas cylinder for adjustable oxygen flow in clinical settings.Record whether the oxygen trolley can be used independently,whether the oxygen cylinder has fallen off accidentally,the stability of the oxygen flow indicated by the oxygen flowmeter,the duration of the transfer,the incidence rate of abnormal events such as heart rate,blood pressure,breathing,and blood oxygen saturation during the transfer process and the outcome indicators for the overall satisfaction evaluation of the oxygen cart usage.Results A total of 58 transports were completed.The purposes were:12 times(20.7%)were for coronary computed tomography angioplasty(CCTA),2 times(3.4%)for magnetic resonance imaging(MRI),1 time(1.7%)for coronary angiography,and 43 times 74.1%)for other treatment areas.No adverse events occurred during the transfer process.All 58 medical staff(100%)were fully equipped with oxygen carts independently,and the average independent loading time was(16.68±0.84)seconds,no accidents occurred with the oxygen cylinders.The satisfaction rate for the use of the oxygen cart was 93.1%,the average total transfer time was(22.03±1.64)minutes.A total of 42 alarms occurred.Among them,19 alarms(45.2%)were due to inappropriate alarm range settings,11 alarms(26.2%)were caused by patients'movments on the bed,and 12 alarms(28.6%)were triggered by contact and conduction issues.There were no alarm cases due to design problems.Conclusions The transport trolley equipped with an adjustable oxygen flow oxygen cylinder has the advantages of easy operation,convenient carrying,no accidental detachment of the oxygen cylinder during transportation,and stable oxygen flow indication by the oxygen meter.This suggests that it can ensure stable oxygen supply for patients during transportation.The overall satisfaction of clinical medical staff with the use of the oxygen trolley is high.关键词
