The Swivel Connector From Roscoe Connects Oxygen Tubing Typically Connected To A Cannula At One End And An Oxygen Source On The Other. Because It Rotates 360 Degrees, The Connector Helps Prevent Tubing From Tangling And Kinking. This Swivel Connector Is Perfect For Patients Who Move Frequently, As It Decreases Torqueing And Increases Mobility By Providing "swivel Action" Between Tubing. Made From Hard Plastic, The Connector Provides Maximum Safety, As It Prevents Tubing From Disrupting The Flow Of Oxygen. This Swivel Device Has 2 Male Ends, Both Ribbed For A Secure Grip And Leak-free Coupling, So A Cannula With A Female End Is Needed To Connect. This Is One Bag Of Connectors And There Are 50 Connectors In Each Bag. There Are No Hard Angles Or Corners On The Connector For Tubing To Get Caught On. The Entire Device Is All Rounded Edges And Gentle Angles. Universal Sized Conical Tips Can Be Easily Attached To Virtually All Oxygen Tubing And Cannulas. Compatible With Clear And Green-tinted Tubing. To Clean, Mix Equal Parts White Vinegar And Water Clean Using A Soft Cloth Or Sponge. Rinse With Water And Allow To Air Dry. Roscoe Mask And Tube Accessories Are Latex-free.
