Abstract
A flow control device with at least one flow channel in a housing that can contain an injection site and/or a pre-biased flow control diaphragm that is stabilized by a flexible contact member. Any flow channel, including that with an injection site, may include a plug acted upon by an external actuator, which can be self-sealing. The injection site with a flexible plug can be used for needleless infusion of fluids, or the flexible plug may be used with a needle for the conventional injection of fluid.
