20130123573 | INTERIOR NEEDLE STICK GUARD STEMS FOR TUBES - Generally described herein are apparatus, systems and methods related to a stem insertable into the access port tubing for the prevention of fluid leaks. More particularly, the stem or stems may be larger than the interior diameter of the access port tubing thereby providing a fluid seal to keep the fluid within the access port tubing. However, these fluid seals might not be absolute and may still allow a certain degree of leakage. In one embodiment, by including barbs which further presses against the interior diameter of the access port tubing, the sealing of the fluid may be substantially improved. The stem itself, while impenetrable by a needle, may still allow for bend flexibility of the access port tubing by employing a ball and socket joint for connecting to a next stem. In this manner, fluid leak prevention is improved while retaining the mobility of the access port tubing. | 05-16-2013 |
