[Empirical Study on the Impact of Infusion Media on the Flow Rate of Infusion Pumps].

Objective: To investigate the impact of different infusion media on the flow rate of infusion pumps.

Methods: Ten infusion pumps were randomly selected and tested for infusion rates using deionized water, saline solution, glucose solution, and parenteral nutrition solution. The infusion flow rate was set at 30 mL/h, and the testing methodology conformed to the standards for the calibration and quality control of syringe pumps and infusion pumps.

[Hospital Networked Medical Equipment Safety Management].

With the continuous improvement and wide application of hospital information, more and more medical equipment is integrated into the hospital information systems, which brings new work contents and challenges for the traditional clinical engineers. This paper reviews and evaluates the current situation of networked medical equipment in the hospital. By applying the ISO 80001 and the MDS(Manufacturer Disclosore Statement for Medical Device Security), the paper puts forward the measures and suggestions for the security management of networked medical equipment.

[Research on the Clinical Alarm Management Mechanism Based on Closed-loop Control Theory].

This paper proposes a clinical alarm management system based on the theory of the closed loop control. The alarm management mechanism can be divided into the expected standard, improving execution rule, rule execution, medical devices with alarm functions, results analysis strategy and the output link. And, we make relevant application and discussion.

[Survey and Discussion on Ventilator Alarm Status in ICU].

Objectives: The article aims at survey and analysis on ventilator alarm status in pediatric hospital.

Methods: First, we design the statistical table of ventilator, and analyze the reliability of statistical table. Then we evaluate the effectiveness of the alarm.
