the longitudinal passage 110 and the connector passage 125 again referring to fig3 sealing ring 150 is disposed between the array of rings 132 and the open end 104 of the luer cleaner 100 the sealing ring 150 preferably has an internal diameter that is approximately the same as the external diameter of the luer 190 see fig1 to prevent fluid forced manually from the reservoir 168 within bulbous body 160 and into the longitudinal passage 110 from flowing out of the luer cleaner 100 between the luer and the body 108 of the cleaner 100 the sealing ring 150 is preferably constructed from kraton u2122 or other suitable flexible material so that the sealing ring 150 generally provides a seal around the luer when the luer is inserted into the luer cleaner 100 a cap 152 is disposed on the open end 104 of the luer cleaner 100 to retain the sealing ring 150 and the array of scrubber rings 132 within the luer cleaner 100 the cap 152 is preferably annular with a generally circular central opening 154 that is sized to allow the luer to be inserted therethrough the cap 152 is preferably fixedly connected to the body 108 such as with an adhesive although those skilled in the art will recognize that the cap 152 may be retained by other methods such as by interference fit or a threaded connection the closed end 106 of the luer cleaner 100 includes a generally bulbous body 160 constructed from kraton.
