Interaction between traction amounts and dispensing rates for the peristaltic finger smart pumps. The polyvinyl chloride (PVC) and polybutadiene (PB) infusion sets are stretched (0–3 cm) and attached to the infusion pump. Then, the dispensing time is measured at a dispensing rate of 100 mL/h. The time required to completely dispense 100 mL of solution, for all combinations of infusion sets and pumps, was significantly greater than the input time (P < 0.01, analysis of variance; mean ± SD, n = 5). The PVC and PB infusion set results were compared using a paired t-test (*P < 0.01). The results of Tukey-Kramer multiple comparisons are shown in Table 2
