Automatic excretion processing devices are assistive equipment that mechanically handle urine or feces for people who have difficulty reaching the toilet. This article explains the differences between urine-only models and those that handle both urine and feces, with product examples, long-term care insurance coverage and precautions.

What are automatic excretion processing devices?

These are urinal systems with automatic suction. They have larger capacities than ordinary urinals, and include urine-only models and models that handle both urine and feces. They are used when getting to or transferring onto the toilet is difficult. They can ease the person’s concern about burdening family members and reduce the assistance required of those changing diapers.

Products with feces-processing functions can be rented by people certified at care levels 4 or 5. Exceptions may apply when essential, so consult a care manager or specialist assistive-equipment adviser.

Automatic excretion processing devices: Points to note

Some products do not support side-lying use

Supported postures and angles vary by device and receiver. For side-lying use or when the person rolls over, check the instructions for supported postures and discuss use with the equipment representative.

Operating noise may be loud

Some people find the operating noise bothersome and have difficulty sleeping.

These devices are not intended to be worn continuously

Rolling over and sitting up are important. The device needs to be removed for activities such as sitting in a wheelchair, so it is used in combination with diapers.

They are not suitable for everyone

They may contribute to skin problems. Discuss use with healthcare or care professionals in advance.

Summary

Use during less active periods, such as nighttime, is recommended. Because the device restricts movement during the day, consider daytime use carefully.
