Medical device assembly

摘要

Medical device assemblies having a connection mechanism for securely connecting a hub to fluid storage containers in a luer slip relationship are described. An exemplary medical device includes a hub forming a cavity, a second indicating element disposed within the cavity that engages the hub. Additional features of the medical device include a second indicating element contoured to form a line contact with the hub. In a specific configuration, the hub includes a first indicating element attached to the hub and extending proximally into the cavity having a protrusion. In a more specific configuration, the medical device includes a fluid storage container that has an indication system for visually indicating optimal fluid-tight engagement of the hub and the fluid storage container.

主权项

1. A medical device for use with a fluid storage device comprising:
a hub comprising a sidewall having an inside surface defining a cavity, an open proximal end and a distal end having an opening therethrough in fluid communication with the cavity, the distal end further including a first indicating element extending proximally into the cavity from the opening; and means for indicating application of a force on the hub sufficient to result in fluid-tight engagement with a fluid storage device, the means comprising a hollow cylindrical body having a proximal end, a distal end and a tapered inside surface extending from the proximal end to the distal end that has a diameter that increases from the distal end to the proximal end forming at least two contact points with the first indicating element during application of the force on the hub.
