23 Jul Culture fluid gas/liquid and liquid/liquid exchanger for tissue engineering tissue bionic cultivation
Abstract
The invention discloses a culture fluid gas-to-fluid and fluid-to-fluid exchanger that is used for biomimetic tissue cultivation in tissue engineering, an inlet and an outlet of a circular culture fluid are arranged in the chamber of an exchanger shell, an inlet and an outlet of a fresh culture fluid are arranged on the shell, an inlet and an outlet that are used for the fresh culture fluid to pass through and for communicating a hydrophilic hollow fiber semi-permeable biomembrane bunch that implements fluid-to-fluid exchange of the circular culture fluid with the fresh culture fluid are arranged in the chamber, a gas outlet and a gas inlet are arranged on the shell, an inlet and an outlet that are used for gas to pass through and for communicating a hydrophobic hollow fiber semi-permeable biomembrane bunch that implements gas-to-fluid exchange of the circular culture fluid with the gas are arranged inside the chamber, and an airtight space is formed inside the chamber of the shell. Oxygen, carbon dioxide, the fresh culture fluid and the circular culture fluid can finish the gas-to-fluid and the fluid-to-fluid exchange and update inside the exchanger without opening the chamber, and the chamber is closed so as to ensure the pulse-typed circulation of the fresh culture fluid and the circular culture fluid and to support the biomimetic tissue cultivation in tissue engineering.
