ABSTRACT
Objective: The theory and repair summary of infusion pump were introduced to improve its maintenance and usage by taking SK-600I infusion pump as an example. Methods:With the cases from practical works including faults such as under-pressure alarm, bubble alarm, block alarms and rate accuracy problem, true or fault respectively, the principle, maintenance, attention issues, fault analyses and repairing methods of infusion pump were presented. Results:To help operators and technicians deal with all kinds of pump failures. Some advices on improving theSK-600I infusion pump design were provided. Conclusion: Infusion pump is a high intelligent medical device, but improper use, mechanical and electrical fault will put adverse impact on its application. Mastering the basic principles, summarizing practical experiences, strengthen operator training, can make better use of infusion pump.
