Abstract

The invention relates to the technical field of medical supplies, in particular to a stem cell exosome preparation fixed-point puncture administration device which comprises a cylinder, one end of the cylinder is in threaded connection with a cover, a power body penetrates through the cylinder, one end of the power body is fixedly connected with a rubber disc, and the end, back to the power body, of the rubber disc is in contact with a first spring. A corrugated pipe sleeves on the power body in the cylinder body, one end of the cover body is fixedly connected with a needle tube, a positioning cylinder is fixedly connected in the cover body, and one end of the needle tube extends into the positioning cylinder. The invention further discloses an administration method of the stem cell exosome preparation fixed-point puncture administration device. The structure design achieves the effect of continuous drug administration, a doctor repeatedly presses the power body, the stem cell exosome fluid in the administration device is continuously injected to a designated position, meanwhile, the main speed can be controlled, and discomfort brought to the human body due to too fast administration is avoided.

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...
