UTERINE CATHETER

摘要

A uterine perfusion catheter has a side opening (5) close to its closed patient end (4). An elastic cuff (10) is attached to the shaft (1) just rearwardly of the patient end opening (5). An inflation lumen (3) opens into the cuff (10) at two locations (13 and 14) towards opposite ends of the cuff. A Y-connector (20) at the machine end of the shaft 1 makes connection to the bore (2) of the shaft and the inflation lumen (3). The cuff (10) is longer than the cervical canal (30) so that opposite ends (11 and 12) protrude from the internal and external os (32 and 33) and can be inflated to seal with both os.
