Definition of single and double tubing for micro drug administration

A micro drug delivery sleeve is a combination of cranial and cerebral administration: it includes a base, an injection tube, and a catheter cap. The head of the injection tube is upgraded and optimized to connect with the PE tube for more convenient, stable, and leak proof sealing. The injection tube is inserted into the base tube and fixed with a locking nut; After the administration is completed, replace the catheter cap and insert it into the base tube to facilitate the growth of new meat into the base tube. The base of the cranial combined drug delivery sleeve is implanted from both sides or one side of the skull to complete drug delivery or electrode placement functions. The injection tube is used for injection drug delivery. Different injection tubes are matched with the base, suitable for precise injection and administration of multiple drugs at the same position or different depth positions. At the same time, a micro drug delivery sleeve is used to improve experimental efficiency. Micro drug delivery sleeves are divided into micro drug delivery single sleeves and micro drug delivery double sleeves

Changsha Maiyue Biotechnology Co., Ltd. specializes in the use of micro drug delivery sleeves for animal brain administration. With the help of a stereotaxic device, the catheter is pre embedded in a specific brain area and can be administered to the brain multiple times over a long period of time through injection of the inner tube, allowing for brain administration while the animal is awake. Micro dose administration sleeves can avoid repeated brain tissue damage caused by repeated punctures. By embedding the sleeves, multiple repeated quantitative administrations can be achieved. Key values such as burial depth can be customized to achieve single or double tube micro administration.
