English to Portuguese Science Medical: Pharmaceuticals radiopharmaceuticals

Os colegas sabem se existe um termo específico para traduzir a expressão "transport pig" (algumas vezes chamado "shipping pig") para o português? Sei que se trata de um dispositivo de transporte mas, ao invés de usar "dispositivo", gostaria de saber se há uma expressão mais específica, uma vez que eles são usados para transportar substâncias radioativas. Agradeço as sugestões!

Texto:

Transport pigs are commonly employed to transport the radiopharmaceutical agents, which are individual doses prepared for individual patients, to the treatment facility. At the treatment facility, data about each unit dose is entered into a facility computer either manually or through reading a bar code, floppy disk, or other similar data format, which may accompany or be on the transport pig or the radiopharmaceutical agent container.

As an example of the foregoing, in PET imaging, an injectable radiopharmaceutical agent such as, for instance, FDG (fluorodeoxyglucose) is fabricated in a cyclotron device at an outside nuclear medicine facility. Thereafter, the FDG is processed to be in a radiopharmaceutical form and is transferred in an individual dose container (i.e. container, bottle, syringe, etc.) and the container is loaded into a transport pig to prevent unnecessary radiation exposure to personnel, such as the radio-pharmacist, technician, and driver responsible for creation, handling, and transport of the FDG from the cyclotron site to the PET imaging site.
