Пожалуйста, помогите перевести.
extension of tubing

Выражение встречается в следующем контексте:
A collection of tubing and connectors that is used to establish an extension of tubing where the length of the tubing in a standard pressure monitoring tubing set is insufficient. It will have physical characteristics appropriate for preserving, to the extent possible, the waveform and fidelity of the measured pressure. This is a single-use device.
