The micro drug delivery sleeve is used in conjunction with a catheter, catheter cap, injection tube, locking nut, and catheter. Using stainless steel as the fluid delivery pipeline, it is directly buried in the tissue to ensure biocompatibility. During long-term observation in animal experiments, the steel wire of the catheter cap is used to ensure that the tissue does not seep into the base hole; When medication needs to be administered, remove the sleeve cap to administer medication or lower the electrode. If a smaller flow rate is required, administer medication through the injection tube. To reduce the damage to animals caused by implanted sleeves, we have developed corresponding base tube sizes based on different body weights: 400um-650um for mice and 650um-800um for dogs and monkeys.
To meet the demand of users for simultaneous injection of two types of drugs, a micro administration double tube has been developed, which can be used for bilateral implantation in the brain and is suitable for injecting two different or the same drugs at two different positions.
