What changed
The USPTO issued patent grant US12594412B2 to Becton, Dickinson and Company, conferring exclusive intellectual property rights for a flush syringe assembly featuring two integrated disinfection cups with absorbent materials, disinfectant/antimicrobial agents, peelable seals, threaded luer lock connections, and snap-fit interlocks for disinfecting medical connector access ports. The 19 granted claims define the enforceable scope of IP protection for this medical device innovation.
Medical device manufacturers and competitors should review the patent's claims scope to assess freedom-to-operate for developing similar fluid delivery and port disinfection systems. The patent creates enforceable exclusionary rights but does not impose compliance obligations on third parties—it restricts competitive use of the claimed invention without authorization from the patent holder.

The integrated disinfection unit includes a first cup and a second cup. The first cup having a chamber containing a first absorbent material, a first disinfectant or an antimicrobial agent in the first cup, and a first peelable seal. The second cup having a chamber containing a second absorbent material, a second disinfectant or an antimicrobial agent in the second cup, and a second peelable seal. A threaded connection is disposed on the bottom exterior surface of the first cup having threads that are sized and pitched to engage threads of a luer lock collar on the distal end of the syringe barrel to allow the first cup to be connected to the syringe assembly. The second cup and the syringe assembly are interlocked through interference fit or snap fit of the thumb press of the syringe and ledge of the second cup.
