ANTI-CONDENSATION SHEATH FOR BREATHING TUBE

摘要

A tube (10) which connects a patient connection (P) with a source (S) of a gaseous mixture used in patient ventilation is provided with a sheath (12) made from a transparent polymeric film laminate the greater part of which comprises vapour deposited aluminium. A central portion (13) of the sheath remains free of aluminium so that the accumulation of condensate in the tube (10) can be observed through the sheath (12) but the heat-reflective properties of the end regions of the sheath inhibit condensation in the tube (10).
