Two channel Vascular Access Harness ™ for rats

The two channel VAH™ connects two independent fluid channels as simply as the standard VAH™ connects one. Uses include bile sampling, simultaneous infusion and blood sampling or simultaneous infusion and blood pressure measurement in rats. Connect 3Fr polyurethane catheters to the ports under the harness dome. Access the ports directly using the needle-free VAH6M injector for manual injections, sampling or flushing. Connect the KVAHD115T tether for continuous access to one channel through a swivel and intermittent access to the second channel through an injection port. Alternatively, connect the VAHD115T tether to a 375/D/22 swivel for continuous access to both channels. Cover the harness ports with the optional VAHD115CAP for protection while in transport or untethered. For bile sampling, attach bile duct and duodenal catheters to the harness then snap in the VAHD115L loop so that bile can flow naturally after surgery. To sample, disconnect the loop and attach a tether.
