Description

technical field

[0001] The invention relates to the technical field of medical supplies, in particular to a fixed-point puncture drug delivery device and a drug delivery method for a preparation of stem cell exosomes. Background technique

[0002] The fixed-point puncture administration process of stem cell exosome preparations in the prior art requires the use of a drug delivery device. The ordinary syringe drug delivery device has a single function and cannot well meet the main needs of safety and stability. It is a problem to be solved to improve the design, improve its stable flow control ability and accurate measurement ability.

[0003] If a fixed-point puncture drug delivery device can be invented, the injection speed control can be realized during the injection process of the drug solution, and the real-time feedback on the injection amount information can solve the problem. For this reason, we provide a stem cell exosome The fixed-point puncture drug delivery devic...
