20230210422 · 2023-07-06 · ·

Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.

The enclosure can include the second seal portion comprising a split, septum seal. The enclosure can include a barrel in structural communication with the second seal portion. The device can include a constriction ring disposed around the barrel, the constriction ring interfacing with the second seal portion to limit movement of the split, septum seal.

Urological device including a valve retained in a urinary catheter
11678968 · 2023-06-20 · ·

A urological device includes a valve retained in a urinary catheter. The urinary catheter has a first portion that is insertable into a urethra and a second portion adapted to remain outside of the urethra when the first portion is inserted into the urethra. The valve has a closed configuration adapted to prevent urine from exiting the urinary catheter and an open configuration adapted to allow urine to flow through and exit the urinary catheter. The valve is adapted to move from the closed configuration to the open configuration in response to a hydrodynamic pressure of at least 750 mm H2O applied to the valve for at least 5 seconds.
