Abstract

Objective: to determine the resistance to degradation in saline solution for different moldable rings for ostomy, as well to confirm if there are any statistically differences between the resistance to degradation in Coloplast moldable rings (Col-2 and Col-4.2) vs. two moldable rings marketed by other manufacturers (Fab1 and Fab2).
Methods: the material object of the trial consisted in four models of moldable rings: Col-2 with 2 mm thickness, Col-4.2 with 4.2 mm thickness, and Fab1 & Fab2 4 mm thickness. The trial sample size was 10 units per type of system. The trials were conducted at the testing laboratory of the Biomechanical Institute, Valencia, using a universal testing machine INSTRON8874/511, under environmental conditions of temperature (23 ºC) and humidity (56%).
Results: the statistical analysis of results revealed statistically significant differences (p< 0.001) between the Coloplast samples (Col-2= 1.84 N and Col-4.2 = 1.97 N) and the samples from manufacturers 1 and 2 (Fab1= 0.90 N and Fab2= 0.92 N). No statistically significant differences were observed between the two Coloplast samples (p= 0.706) or between the two samples from the other two manufacturers (p= 0.917).
Conclusion: the two Coloplast samples presented significantly higher penetration strength values (twice higher) than the samples from the other two manufacturers; and therefore, higher resistance to degradation at six hours of being immersed in saline. However, no statistically significant differences were observed in terms of resistance to degradation between both Coloplast samples, regardless of the different thickness of the rings. This effect was due to measurements being conducted with 1mm penetrations.
