Embodiment Construction

[0016] It would be advantageous to provide a self-sealing needle-free connector that accommodates a male luer fitting that meets ISO standards while reducing the size of the connector and thus the fluid volume in the connector compared to conventional connectors.

[0017] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that embodiments of the invention may be practiced without some of the specific details. In other instances, well-known structures and techniques have not been shown in detail in order not to obscure the disclosure. In referenced figures, elements bearing the same reference number are identical or substantially similar. Reference numbers may be suffixed with a letter to indicate individual instances of a common element, whereas, in the absence of a suffix letter, such instances are generally desi...

Abstract

A female connector has a body with an internal cavity having a port and an internal surface. A collapsible valve is disposed within the internal cavity. The valve has a head with an external surface, wherein the head is in sealing contact with the internal surface of the internal cavity at a first location separated from the port so as to create a primary seal and at a second location proximate to the port so as to form a secondary seal when the female connector is not mated with a compatible male connector. The valve also has a neck coupled to the head proximal to the primary seal. The neck has a smiley cut. The valve also has a base portion coupled to the neck proximal to the smiley cut.

Description

[0001] Cross References to Related Applications [0002] Not applicable technical field [0003] The present disclosure relates generally to needleless connectors, and more particularly to a connector having a collapsible internal valve. Background technique [0004] Medical treatment often involves administering medical fluids, such as saline solutions or liquid medications, to a patient using an intravenous (IV) catheter connected to the Fluid sources such as IV bags. While the fitting typically includes an interconnectable male and female needleless connector with a "Luer taper" that conforms to the International Organization for Standardization (ISO) standard, some needleless The connector may not have a Luer tip. Certain connectors have self-sealing features to prevent fluid from leaking out of the attached tubing when the connector is separated from a mating connector. [0005] Figure 1A A conventional needleless connector 10 is shown having a collapsible inner va...
