Abstract: A valve retainer for securely attaching a valve to a flexible tube of a medical device comprising a tubular body having tabs extending from one end of the retainer that are deflectable inwardly of the retainer to positions extending adjacent the inner surface of the retainer and the outer portion of the tube so that the tabs prevent withdrawal of the valve from the flexible tube.

Abstract: A method of making a suction catheter having grooves and suction holes in the grooves is disclosed which includes the step of clamping a tube to effect a bulge and moving a knife longitudinally of the tube to skive the outer portion of the bulge to form a groove after clamping pressures are removed. Holes are formed in the bottom walls of the grooves. Skiving apparatus is disclosed which includes a clamping device for positioning and bulging a tube adjacent one end, and a knife relatively movable longitudinally of the tube to skive the bulge.

Abstract: A medical tube connecting device which includes a tube connector and a security connection member for connecting a medical tube, such as a tracheal tube, to a slip-fit coupling adapter of gas supply equipment. The connector has slip-fit couplers for connection with the adapter and the tube, and a flange with a pair of diametrically opposed slots extending inwardly from its outer periphery. The security member is an elastic strap having opposed end enlargements. The strap, in use, extends around a portion of the coupling adapter and the ends of the strap are received in the flange slots with the enlargements maintaining the strap in place.
