Venous access device
A venous access device includes a hub and a bifurcated cannula. The hub includes a bifurcated connecting arm, a blood sampling arm connected to the bifurcated connecting arm, a fluid transfer arm connected to the bifurcated connecting arm, a blood sampling channel and a fluid transfer channel. The blood sampling channel passes through the blood sampling arm and the bifurcated connecting arm. The fluid transfer channel passes through the fluid transfer arm and the bifurcated connecting arm. The bifurcated cannula is coupled to the bifurcated connecting arm and includes a blood sampling lumen having a blood sampling port, a fluid transfer lumen having a fluid transfer port, and a dividing member separating the blood sampling lumen from the fluid transfer lumen. The blood sampling port is 2 mm to 20 mm proximal from the fluid transfer port. The blood sampling channel is fluidly connected to the blood sampling lumen, and the fluid transfer channel is fluidly connected to the fluid transfer lumen.

AUTOMATIC INVASIVE DEVICE FOR BODY
The present invention relates to an automatic invasive device for body and, more particularly, to an automatic invasive device for body comprising a body press unit capable of pressing a human body part to detect a puncturing position. The present invention also relates to an automatic invasive device for body comprising at least one of a rotatable probe unit, a vacuum tube driving unit, and a body contact material supply unit. The automatic invasive device for body according to the present invention comprises: a syringe needle unit support part that supports a syringe needle that enters the body; and a press unit (500) that presses the body that has a site to be subjected to an invasive procedure.
BLOOD SAMPLE OPTIMIZATION SYSTEM AND BLOOD CONTAMINANT SEQUESTRATION DEVICE AND METHOD
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.

Integrated Catheter System for Blood Draw at the Time of Placement and with Enabling Feature for Blood Draw During Indwell
An integrated peripheral intravenous (IV) catheter configured for blood draw both at the time of catheter placement and during catheter indwell. The peripheral IV catheter includes a catheter adapter having a catheter configured to be inserted into a patient's vasculature and a side inlet defining a fluid pathway into and out of the catheter. The peripheral IV catheter also includes a side port member having a main branch, the main branch including a distal end configured to couple the side port member to the side inlet of the catheter adapter and a connector portion accessible via a proximal end of the main branch. Additionally, the peripheral IV catheter includes a blood collection adapter removably and directly coupled to the connector portion of the side port member at the proximal end of the main branch. Furthermore, side pore member of the peripheral IV catheter may include a side branch.
Biological fluid collection and stabilization system
A biological fluid collection system that receives a sample and provides flow-through blood stabilization technology and a precise sample dispensing function for point-of-care and near patient testing applications is disclosed. A biological fluid collection system of the present disclosure is able to effectuate distributed mixing of a sample stabilizer within a blood sample and dispense the stabilized sample in a controlled manner. In this manner, a biological fluid collection system of the present disclosure enables blood micro-sample management, e.g., passive mixing with a sample stabilizer and controlled dispensing, for point-of-care and near patient testing applications.
Syringe for obtaining a target volume of blood
The present invention provides a syringe for obtaining a target volume of a liquid, in particular blood. The syringe provides a piston with a seal having a width that is identical to the volume line indicating the target full volume of the syringe. This offers a precise and an intuitive way for the end user to understand how much blood is recommended to be drawn from the patient. In exemplary embodiments these visual indicators have the same colour and a desired amount of interruptions of the line of the volume scale are provided.
