Abstract:
Objective:A practical length regulator of extended tube for microinjection pump was made and its clinical effect was observed. The method and basis were provided for the orderly management of various infusion pipelines in clinic.
Methods:The texture, inner diameter and color of the regulator are designed. Sixty patients who needed to use three or more lengthened tubes at the same time and were pumped through the same vein passage were randomly divided into two groups: the regulator group and the non-regulator group. 31 patients in the regulator group and 29 patients in the routine group were observed continuously for 3 days. During the study period, the number of tube shedding and the number of nursing errors were recorded. The average time required for the same dose of drugs to be pumped into the body was 10 ml/h, 25 ml/h and 50 ml/h, respectively. The average time spent by the nursing staff when the drugs were randomly changed or suspended was investigated in 52 cases. Staff satisfaction with its clinical application.
Results:The number of errors and tube shedding in the regulator group were 5 and 2 times respectively, and 34 and 9 times respectively in the routine group (P < 0.05). The time required for the regulator group to pump the same dose at the same rate was 295.33, 120.07 and 59.97 seconds, respectively. The time required for the conventional group was 294.63, 119.83 and 59.87 seconds, respectively, with no significant difference (P > 0.05). The average time needed for drug replacement or suspension was 47.05 seconds in the regulator group and 91.68 seconds in the routine group (P < 0.05). The satisfaction of the two groups was 84.98 and 94.5 respectively (P < 0.05).
Conclusion:Compared with the conventional group, the regulator group can reduce the workload of nurses without increasing the risk of clinical use. The regulator is a safe, reliable and convenient pump pipe management device for pumps.
