Abstract: A tubular adapter and check valve for Luer fittings. The end of the adapter that receives the Luer fitting is expandable radially outwardly in a substantially uniform manner so that Luer fittings of all sizes are snugly received by the adapter.

Abstract: A ball valve device for controlling fluid flow has a stainless steel ball positioned in the lumen of an I.V. tube. The outer diameter of the ball is equal to the inner diameter of the I.V. tube, so that the outer surface of the ball establishes a fluid seal with the inner surface of the tube. A latex sheath surrounds the tube in the proximity of the ball to provide resilience and memory for the tube. Inserts are positioned in the lumen both upstream and downstream from the ball to hold the ball in position under the sheath. Each insert is formed with a lumen for fluid flow, and has a tapered surface adjacent to the ball, which prevents the ball from forming a seal with the insert.

Abstract: A flow regulator for liquid to be administered parenterally to a patient comprises a first member having a flow passage therein for the liquid and a second member arranged to be adjustably telescoped in the passage. The first and second members are constructed such that they can be telescopingly positioned to form a flow rate controlling channel which restricts the flow rate as a function of the length of the channel. The length of the channel is adjustable by changing the relative position of the first and second members. An adjustment force applied to the outside of the regulator is transmitted to the second member within the flow regulator for changing the channel length and therefore the flow rate. The flow regulator can include a drip chamber positioned immediately above the second member for convenient adjustment of the flow rate. Sealing against leakage of air into the flow regulator is attainable because the flow rate controlling second member is located entirely within the first member.

Abstract: The valve includes a housing with inlet and outlet members joined by a resilient flexible valve closure. An annular chamber that does not communicate with the inlet or outlet surrounds the valve closure. When a flow of fluid is desired through the valve closure, a pressurized fluid is introduced into the annular chamber to deform the valve closure enabling the closure to open. Reduction or elimination of the pressure for deforming the valve closure permits the valve closure to assume its normal closed position, thereby permitting a shut off of fluid flow. Variable flow rates can be accomplished by obtaining predetermined deformations of the valve closure corresponding to predetermined levels of the pressurizing fluid which cause such deformation.
