Description of Nuclear Medicine Injection Protection Cart

The nuclear medicine injection protection cart—also known as a radiopharmaceutical injection trolley or lead-shielded injection station—is essential radiation protection equipment for nuclear medicine departments, PET/CT centers, and SPECT examination rooms. The lead shielding thickness is typically adjustable between 2 mm Pb and 50 mm Pb, depending on the energy of the radionuclides being handled; for instance, high-energy positron-emitting radionuclides require higher-density tungsten alloy or thicker lead layers. A large lead-glass viewing window (e.g., 200 mm × 250 mm) is incorporated to ensure the operator maintains a clear view of the injection process and the patient's reaction while remaining shielded. The unit is mounted on four heavy-duty, silent swivel casters, with at least two featuring independent locking brakes; this configuration ensures both mobility and absolute stability during injections, preventing accidental contamination or needlestick injuries caused by the cart sliding. Designed for the safe handling of highly active radioisotopes (such as 99mTc and 18F-FDG), the cart utilizes physical shielding to minimize ionizing radiation exposure for medical staff during dose preparation, injection, and transport, while simultaneously ensuring biosafety for patients and the environment.

Application of Nuclear Medicine Injection Protection Cart

PET/CT and SPECT examination rooms: Used for the final dose dispensing of 18F-FDG and 99mTc-labeled agents, as well as for intravenous administration to patients.

Radiotherapy wards: Used for the administration of therapeutic radiopharmaceuticals, such as Iodine-131.

Clean dispensing room: Certain smart shielded carts can dock with automated dispensing robots, enabling sterile transfer from non-clean areas to clean areas.

Standard Operating Procedure

Preparation Phase: Move the shielded cart to the designated operating position and lock the casters. Ensure the lead-glass viewing window is clean and unobstructed.

Medication Retrieval and Shielding: Retrieve the radiopharmaceutical using a dedicated lead canister or a tungsten alloy syringe shield, and place it on the cart's tray or in the designated holder.

Injection Procedure: Position yourself behind the radiation shield and observe through the lead-glass window; administer the injection using an extension tube or by directly holding the shielded syringe.

Waste Disposal: Dispose of used needles and empty vials directly into the puncture-resistant, leak-proof radioactive waste container integrated into the cart.

Cleaning and Disinfection: Upon completion of the procedure, wipe stainless steel surfaces with a medical-grade disinfectant to remove any potential surface contamination.
