Ostomy bag preparation device

A method for preparing an ostomy bag system, comprising:

• aligning an elongated housing of a device with a diameter of a stoma of a subject, the elongated housing comprising at least one groove that extends at least a portion of a length of the elongated housing, and the device comprising:
• a cutting tool comprising a blade, the cutting tool at least partially surrounding a first portion of the elongated housing, wherein the at least one groove of the elongated housing is configured to receive the cutting tool to guide translation of the cutting tool along the elongated housing;
• a measurement guide at least partially surrounding a second portion of the elongated housing, wherein the at least one groove of the elongated housing is configured to receive the measurement guide to guide translation of the measurement guide along the elongated housing;
• a handle comprising a pinion inserted to an opening of the elongated housing, the handle operably coupled to the cutting tool by a first rack and to the measurement guide by a second rack, the first rack and the second rack disposed within the elongated housing;
• and
• a cutting base coupled to the elongated housing at an end of the cutting base, the cutting base comprising a first planar surface and a second planar surface opposite the first planar surface;
• engaging the handle to cause the cutting tool and the measurement guide to translate along the elongated housing such that each of the measurement guide and the cutting tool align with the diameter of the stoma;
• inserting the cutting base into an opening of an ostomy bag;
• and
• while the first planar surface of the cutting place receives the blade of the cutting tool, rotating the elongated housing to cut through an adhesive portion of the ostomy bag using the blade of the cutting tool.
