ABSTRACT:
An insulating sleeve retains heat in the plastic of a flexible plastic medical tube when the plastic of the medical tube is dielectrically heated by a radio frequency tubing sealer. The heat retained by the insulating sleeve permits additional melting of the plastic of the medical tube after a seal has been formed. The additional melting results in forming an easily tearable web between the segments of the medical tube in the same operation as the sealing operation. The medical tube is selectively sealed without forming the easily tearable web by using the radio frequency tubing sealer without the insulating sleeve.
