A liquid jet ejection device is provided. The liquid jet ejection device has a flexible lumen having an intake end positioned to be in fluid communication with a liquid source, and an output end distal from the intake end. A pump is coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end. A body structure extends from a handle and supports the output end of the flexible lumen, the body structure having a base form in which the output end of the flexible lumen is supported in a base pose relative to the handle, the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact.
