Dual purpose adapter
First Claim
1. A dual use adapter, comprising:
- a first tubular portion having at least one protrusion along an exterior surface; and
a second tubular portion, coaxially located with respect to the first tubular portion, having a first end within the first tubular portion and a second end external to the first tubular portion and having a stepped internal lumen forming the plurality of internal diameters;
the second tubular portion formed of a more pliable material than the first tubular portion.

Abstract
A connector is provided that can be used for both fluid aspirating applications and fluid introduction applications without a requirement for additional adapters. Direct connection to a vacuum tube or an enteral feeding connector can be possible without need of an additional rubber sleeve and/or an additional enteral feeding adapter. In one example, a first tubular portion has at least one protrusion along an exterior surface. A second tubular portion is also provided and coaxially located with respect to the first tubular portion. The second tubular portion has a first end within the first tubular portion and a second end external to the first tubular portion. The second tubular portion can have a stepped internal lumen forming the plurality of internal diameters and can be formed of a more pliable material than the first tubular portion. A method for forming a dual use adapter is also provided.
