1. A urine-sampling system for aseptic urine sampling comprising:
a catheter assembly including 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 thread pattern in which;
a first lead has a lead diameter greater than a second lead, and
a lead pitch of the first lead or the second lead is a multiple of a pitch between adjacent crests or roots of the first lead and the second lead; and
a sampling-port access device including a barrel tip at an end of a barrel configured to fluidly connect the sampling-port access device to the urine-sampling port of the catheter assembly, the barrel tip also having the thread with the thread pattern in which the first lead has the lead diameter greater than the second lead,
wherein each of the barrel tip of the sampling-port access device and the urine-sampling port exclusively mates with the other of the barrel tip of the sampling-port access device and the urine-sampling port exclusive of a standard medical-industry fastening system, thereby ensuring proper mating of the barrel tip of the sampling-port access device and the urine-sampling port for aseptic urine sampling.
