Semi-disposable ventilator breathing circuit tubing with releasable coupling

摘要

A coupler having a releasable compression fitting connects a length of tubing to a ventilator fitting. The compression fitting allows the tubing to be made of economical and re-usable materials that would otherwise be difficult to attach to a ventilator fitting. The coupler may have a conical end that can be directly attached to a ventilator fitting, or it may have a barbed end over which an elastomeric endpiece is attached, which in turn can be attached to a ventilator fitting. The tubing and coupler may be sterilized and re-used.
