Economy Cuffed Endotracheal Tubes (Silicone) - 10.0-14.0mm. Silicone is the preferred material for endotracheal tubes. However, until now the cost was considered too high for use in many veterinary clinics. This is especially true on the larger sizes above 10mm. Endotracheal tube with inflatable cuff. Connector included. Lateral murphy eye at distal tip. Silicone is a soft material that conforms to body contours and is more comfortable for the patient. The soft distal tip lessens the chance for any airway tissue damage. Reusability. Intended to be used over and over again. Not Autoclavable though. Silicone resists deterioration better than PVC or red rubber. Transparent. See any blood and mucous if they develop. Radiolucent. Available in sizes 10, 11, 12 and 14mm. Other sizes available on request.
