A central event in Elise Sørensen's life was caring for her sister, Thora, who underwent a colostomy operation. The primitive and inadequate colostomy appliances available at the time caused significant distress and embarrassment for Thora. This personal experience ignited Sørensen's desire to improve the quality of life for individuals with colostomies.

Witnessing her sister's discomfort and the limitations of existing colostomy care motivated Elise Sørensen to seek a more dignified and practical solution. The emotional toll on Thora and other patients likely drove her innovative spirit.
