Mobile Therapy and Diagnosis Toilet

As part of the implementation of Radiopharmaceutical Therapy (RPT) treatments, particularly those involving radiopharmaceuticals labelled with ¹⁷⁷Lu, Nuclear Medicine departments may encounter constraints in the management and storage of long half-life radioactive waste. Indeed, as stipulated in the “Circular Letter on the Changes in the Conditions of Authorisation of Nuclear Medicine Departments by the ASN for the Possession and Use of Lutetium-177”, urinesamples must be collected from patients within at least six hours after administration of the radioactive drug, even if the department does not have a shielded room.

Lightweight and easy to manoeuvre, the mobile therapy toilet developed by Lemer Pax addresses this issue by combining a toilet mounted on a frame, eliminating the need for Nuclear Medicine departments to install dedicated decay tanks. Radioactive waste is collected in specialised bags placed inside a mobile container that provides radiation shielding equivalent to 6 mm of lead and 10 mm of plastic.

Focus on Therapy and Diagnosis Toilet:

• The main body of the toilet is made from smooth materials to facilitate disinfection and decontamination.

• Equipped with four wheels (including two rear wheels with brakes) and two handles, the lightweight rolling frame, made of painted, decontaminable aluminium, allows the mobile therapy toilet to be easily moved close to the patient or to a suitable area. Fitted with two pivoting armrests, the frame enables the patient to use their arms for improved ergonomics and support.

• Designed for quick, simple, and safe installation, the bag fitted to the toilet prevents contamination of the toilet bowl and enables the collection of all effluents produced by the same patient. Each bag is fitted with a leaktight sealing system and contains a solidifying gel or absorbent pad, allowing all liquids to be solidified

• The mobile container holds the bag beneath the toilet bowl. This container can be considered a shielded decay container on wheels, providing radiation protection equivalent to 6 mm of lead and 10 mm of plastic. At the end of the day, the shielded drum containing the bag is closed with a shielded lid equipped with a secure closure mechanism before being transported to the decay storage area.

• The shielded toilet seat on the toilet bowl helps keep the bag in place for the same patient. Lightweight, weighing only 3 kg, this toilet seat helps contain both odours and contamination throughout the patient’s treatment (up to 1 day).
