    摘要: An apparatus to control blood flow through an intravenous catheter in accordance with the present invention may include a substantially resilient helical outer shell and an inner valve portion formed therein. The inner valve portion may be configured to open upon compressing the substantially resilient helical outer shell. In some embodiments, the inner valve portion may include mating portions that substantially align to provide fluid leakage therebetween. Compressing the substantially resilient helical outer shell by, for example, inserting a Luer device into a catheter adapter containing the substantially resilient outer shell, may cause the mating portions to misalign, thereby creating a fluid path.

    摘要: A medical access device provides needleless access to patient fluid lines such as intravascular catheters. A preformed crimp ring is attached around a septum and the top end of the housing of the medical access device. The crimp ring is configured to hold the septum in place. The septum provides access for a tubular portion of a medical device such as a male luer taper of a syringe. The crimp ring is then attached by mechanical attachment and/or chemical adhesion to the housing to minimize axial and rotational movement between the septum and the housing.
