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 container comprising:
a hub including 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; a first indicating element having a distal end attached to the distal end of the hub and a free proximal end extending into the cavity, the first indicating element forming a peripheral recess with the sidewall of the hub; and a second indicating element disposed in the cavity of the hub including an open proximal end, an open distal end and a body extending from the open proximal end to the open distal end, the body portion having an inside surface defining a hollow interior for enveloping the first indicating element to permit the body to enter the recess of the hub upon application of a distally directed force on the second indicating element, the inside surface defining a first diameter region, a second diameter region and a third diameter region, the second diameter region has a diameter that is greater than the diameter of the first diameter region and a diameter that is smaller than the diameter of the third diameter region.
