23 Jul Preparation device of tubular bracket for tissue engineering
Abstract
The utility model discloses a preparation device for an organization engineering-used tubular support, which comprises a base, as well as an inner tube and an outer tube arranged coaxially, and is characterized in that a positioning plug is coaxially sleeved at one end of the inner tube; a positioning hole is formed on the base; the positioning plug is in interference fit with the positioning hole; one end of the outer tube is a closed end; a sample adding hole is formed on the closed end; and the other end of the outer tube is an opening end which is coaxially sleeved on the positioning plug. The preparation device has the advantages that the structure is simple and the positioning is exact; since the positioning plug is in interference fit with the positioning hole, the fit length of the positioning plug and the positioning hole is larger than or equal to the fit length of the positioning plug and the out tube, so as to enable the inner tube to be positioned well on the base, thereby guaranteeing the vertical degree; the concentric degree between the inner tube and the outer tube can be exactly guaranteed after the outer tube is matched with the positioning plug; when tubular supports with different wall thicknesses are required to be made, the outer tube is only needed to be changed.
