PORT SEALING CARTRIDGE FOR MEDICAL VENTILATING AND ASPIRATING DEVICES

摘要

There is provided a port sealing cartridge that allows for insertion of a catheter or other medical device into an endotracheal tube and thence the patient's lungs through an available access port. The port sealing cartridge has a primary and a secondary seal or collar that sequentially provide a pressure seal as a medical device is inserted through them and into the system. An optional tethered dust cover may also be used on the proximal end of the port seal cartridge. The port seal cartridge may desirably be fitted with a quick-connection so that it may be easily removed, disposed of and replaced. The port seal may be used for access to a patient's lungs with a bronchoalveolar catheter, bronchoscope or other medical device for treatment or sampling of the respiratory tract.
