3D Cell suspension maintaining device of bio-material for bio 3D printer and method thereof

摘要

The cell suspension holding device for a biomaterial for a bio 3D printer according to the present invention is detachably coupled to a syringe-shaped syringe, slidingly coupled along the inner circumferential surface of the syringe inlet, and formed in the longitudinal direction of the syringe to prevent air from outside and air. A body having an air passage through which it can be communicated; A pipette fixture connected to the air passage and having an air outlet through which air communicates into the syringe, extending downward of the body, and having an outer diameter decreasing downwardly; A syringe fixing arm fixed to the syringe in a form protruding from the body in a direction perpendicular to the longitudinal direction of the syringe to surround the upper flange of the syringe; And a pipette that is coupled to the pipette fixture and has a hollow tube shape whose inner diameter decreases as it goes downward, and has a lower end disposed at the outlet of the syringe, wherein the biological material accommodated in the syringe is discharged to the lower side of the syringe. It is characterized in that it is configured to periodically apply an air pressure between a preset minimum pressure and a maximum pressure to the upper end of the air passage during the period during which the air passage is not.
