Systems For Aseptic Urine Sampling And Methods Thereof

A catheter assembly comprising:

• a urinary catheter;
• drainage tubing;
• and
• a connector fluidly connecting the urinary catheter to the drainage tubing, the connector including a urine-sampling port having a thread with a left-handed thread pattern, a thread pattern in which a first lead has a lead diameter greater than a second lead, a thread pattern having more than two leads, or a left-handed thread pattern having more than two leads configured to mate with a complementary thread of a tip of a sampling-port access device, thereby ensuring proper mating of the urine-sampling port and the sampling-port access device for aseptic urine sampling.

A sampling-port access device comprising:

• a barrel;
• a hollow needle including a tip, the needle coaxially disposed within the barrel such that the tip of the needle is protected by the barrel;
• and
• a tip at an end of the barrel fluidly connected to the needle, the tip of the barrel having a thread with a left-handed thread pattern, a thread pattern in which a first lead has a lead diameter greater than a second lead, a thread pattern having more than two leads, or a left-handed thread pattern having more than two leads configured to mate with a complementary thread of a sampling port of another device, thereby ensuring proper mating of the sampling-port access device and the sampling port of the other device for aseptic sampling.
