Abstract:Objective To compare the effects of perfusion tube and pressure air gun on endoscopic channels drying by using the stripped endoscope model, so as to explore the application value of perfusion tube in endoscopic channels drying.Methods After the standard manual cleaning and disinfection process, the stripped endoscope model was randomly divided into group A and group B. Each group was subjected to 30 tests. Group A was injected with a perfusion tube, and group B was injected with a pressure air gun. The liquid residues in the endoscope tubes were observed visually and with a magnifying lens, and the time of thorough drying of the endoscope channels and the physical fatigue of the operators were compared between the two groups.Results The average drying time of the group A was (366.47 ± 75.74) s, the average drying time of the group B was (338.40 ± 65.81) s, there was no significant difference between the two groups (t = -1.53, P = 0.131). The fatigue degree of the group A was lower than group B (t = 16.79, P < 0.01).Conclusion There is no statistical difference in the air delivery time between the perfusion tube and the pressure air gun drying endoscopic tube, and the operator's physical fatigue is light when the perfusion tube is used, so it is recommended to use the perfusion tube drying endoscopic tube in clinic.
