US Patent 11937778 Apparatuses and methods for determining if an endoscope is contaminated

Apparatuses and method for determining if an endoscope is contaminated may include a sheath device to cover both the inside and outside of the endoscope. The sheath device may include a flexible tubular external sheath that extends over the endoscope to form an external protective barrier, a tubular internal sheath that extends within a lumen of the endoscope that forms an internal protective barrier, and a cap sealed to both the external sheath and the internal sheath, and a proximal sealing collar that is configured to allow the space between the endoscope and the external and/or inner sheaths to be pressurized to detect leaks indicating contamination.
