International Classification:
A61M 532
US Classification:
604174, 604180, 128898
Abstract:
A sheath device comprises a substantially rigid elongated body adapted to receive a chest tube. The body includes a first end and a second end, flexible seal at the first end, and an air-impermeable flexible joint at the second end. A base having a first side and a second side is provided at the joint, wherein the first side is connected with the flexible joint and the second side includes an adhesive for securing the base to a patients chest. A method of preventing pneumothorax in a patient having a chest tube removed comprises attaching the sheath device to the patients chest at the time of the chest tube placement, later withdrawing the chest tube into the airtight chamber of the sheath, and sealing the sheath device. Removing the base and flexible joint of the sheath device from the body of the sheath device leaves an air-impermeable dressing on the patients chest.
