Abstract: A portable sanitization device and associated systems and methods are disclosed herein. The device includes a fluid chamber containing a sanitizing fluid, a pump, and a spray nozzle configured to direct a pressurized fluid stream outwards from the device. The fluid chamber, the pump, and the spray nozzle can each be contained in a housing component of the device. The housing can have an anti-bacterial outer surface and an ergonomic design that aids convenience in using and/or discretely transporting the device. The pressurized fluid emitted from the device can be used to wash contaminants away from the user's groin region after using the restroom. In some embodiments, the device provides multiple pressure settings, allowing the user to adjust the pressure of the pressurized fluid stream based on the use, their comfort level, soil levels, and/or various other concerns.
