Abstract
An access port for the introduction of a needle cannula tip into an IV tube set includes a rigid tubular housing and a resilient member disposed adjacent an inlet of the housing. The resilient member includes an axial perforation extending through the resilient member, and is normally closed by the resilient character of the resilient member. A depression is defined in a proximal face of the resilient member, and includes sidewalls extending between the proximal face and the axial perforation to guide the tip of the cannulated needle toward the perforation as the cannulated needle is introduced into the access port.
Claims12
An access port for the introduction of a needle cannula tip into a IV tube set comprising:
- a rigid housing including an inlet, an outlet, and a bore extending therebetween and defining a longitudinal axis of the access port;
- and
- a resilient member comprising:
- a distal face positioned adjacent the housing and covering the housing outlet;
- a proximal face opposite the distal face;
- an axial perforation extending through the resilient member, the axial perforation normally closed by the resiliency of the resilient member;
- and
- a depression defined in the proximal face, the depression including sidewalls extending between the proximal face and the axial perforation, the sidewalls including both an axial and radial component such that the sidewalls may serve to guide a cannulated needle tip toward the axial perforation.
A method of administering an injectable pharmaceutical through an IV access port, the method comprising the steps of:
- providing a needle cannula including a slanted cutting edge at a distal end of a tip member thereof, the tip member including an opening in fluid communication with a lumen extending through the needle cannula;
- providing the injectable pharmaceutical in a vial including a septum;
- providing a pre-pierced access port in fluid communication with an IV tube set, the access port defining a longitudinal axis and including a resilient member having a depression defined in a proximal face thereof, the depression including sidewalls having both an axial and radial component, and a distal-most region of the depression intersecting an axial perforation defined through the resilient member;
- penetrating the vial septum with the slanted cutting edge of the needle cannula and inserting the tip member into the injectable pharmaceutical;
- withdrawing the injectable pharmaceutical from the vial into the lumen extending through the needle cannula;
- withdrawing the tip member of the needle cannula from the vial;
- approximating the tip member of the needle cannula with the resilient member of the pre-pierced access port until the tip member abuts a sidewall of the depression;
- and
- advancing the tip member axially against the sidewall of the depression to guide the tip member radially toward the axial perforation.
A drug vial, comprising:
- a container having a first end with an orifice;
- and
- a resilient member comprising:
- a distal face positioned adjacent the first end of the vial;
- a proximal face opposite the distal face;
- an axial perforation extending through the resilient member;
- and
- a depression defined in the proximal face, the depression comprising sidewalls extending between the proximal face and the axial perforation.
