M8120 Microdose double cannula

The microdose cannula is used together with the catheter, catheter cap, injection inner tube, locking nut and catheter. Stainless steel was used as the fluid drug delivery pipeline to directly bury it in the tissue to ensure biocompatibility. During long-term observation in animal experiments, the steel wire of the catheter cap was used to ensure that the tissue did not penetrate into the base hole; When drug administration is needed, pull out the sleeve cap to give drug or lower the electrode. If smaller flow rate is needed, the drug can be administered through the injection tube. In order to reduce the damage of implanted cannula to animals, we formulated the corresponding base main pipe size according to different body weights: rat 400um-650um, dog monkey 650um-800um.

In order to meet the user's demand for simultaneous injection of two kinds of drugs, a micro dose double cannula is developed, which can be used for bilateral implantation in the brain, and is suitable for the injection of two different or the same drugs at two different positions.
