Abstract
Abstract A luer cap for use on ports of medical devices such as cardiotomy reservoirs and blood sets. The cap comprises an outer wall (10) having a generally circular cross-sectional shape. An inner wall (12) and end wall (20) define an internal port receiving cavity (13). The inner wall (12) is threaded to mate with threads or a flange on a female luer port. The mating surfaces of the luer cap and the luer port can be sterilized through a hollow tubular portion (18), end wall (20), and outer wall (10) of the luer cap.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
In a medical device having a port comprising an annular wall, an axial bore defined within said annular wall, and thread engaging means carried by said annular wall, the improvement comprising, in combination: a cap mounted on said port, said cap comprising a circular sidewall having an inside wall surface; a hollow tubular portion disposed interior of said sidewall and defining an internal port-receiving cavity between and defining an internal port-receiving cavity between said tubular portion and the inside surface of said sidewall for receiving said annular wall of said port, said hollow tubular portion of said cap being disposed within the bore of said port when said annular wall of said port is received within said port-receiving cavity; said hollow tubular portion being closed at one end by an end wall and open to the atmosphere at the opposite end; and the inside surface of said cap sidewall carrying threads for engagement with the thread engaging means of said annular wall of said port.
Claim 2
Dependent Claim
165 words
