Abstract: A method of distributing educational content over a network is disclosed. Educational content is divided into topics and the topics are split into smaller educational units. Professionals reviewing the material for accreditation purposes choose particular units to study and are subject to minimum and maximum time parameters. The partitioning of educational topics allows advertisers to deliver episodic advertising over an extended time period.

Abstract: A medical connector adapted for placement between a catheter and a medical infusion or injection source includes a pair of interlocking half medical connector portions, one side of which attaches to the infusion source and the other side of which is coupled to the catheter connected to the patient and a locking mechanism for locking a medical connector portion to a medical fitting. The connection to the catheter and the infusion source can be via standard medical luer taper fittings, with or without specially designed locking mechanisms that prevent inadvertent disconnection. The medical connector itself is uniquely shaped and includes a raised surface feature and a recessed surface feature formed on the medical connector portions.
