Embodiment 1
[0009] Embodiment 1: the preparation of polycaprolactone (PCL) three-layer artificial blood vessel
[0010] Preparation of the inner layer of the artificial blood vessel: Weigh 2.0 g of PCL with a number average molecular weight of 80,000 and add it to 10 ml of chloroform, stir and dissolve at room temperature overnight to prepare a PCL solution with a concentration fraction of 20% (mass / volume). The inner layer of the artificial blood vessel was prepared by direct printing in a fume hood at room temperature. Install the 2.0mm diameter stainless steel receiving rod on the printer. Aspirate the PCL solution into the syringe, mount the syringe on the syringe pump, and position the syringe needle 2 mm above the metal receiving rod. Set the advance speed of the syringe pump to 2ml / h, the rotational speed of the receiving rod to 100rpm, the lateral movement speed to 0.2mm / sec, and the printing time to 2min. After the preparation, the receiving rod with the inner layer of the artif...
Embodiment 2
[0013] Embodiment 2: Preparation of poly L-lactide-caprolactone (PLCL) three-layer artificial blood vessel
[0014] Preparation of artificial blood vessel inner layer: Weigh 1.5g PLCL and add it into 10ml tetrahydrofuran solvent, stir and dissolve overnight at room temperature to prepare a PLCL solution with a concentration fraction of 15% (mass / volume). The inner layer of the artificial blood vessel was prepared by direct printing in a fume hood at room temperature. Install the 3.0mm diameter stainless steel receiving rod on the printer. Inhale the PLCL solution into the syringe and install it on the syringe pump. Place the needle of the syringe at a distance of 3.0mm above the metal receiving rod, set the advancing speed of the syringe pump to 3ml / h, the rotating speed of the receiving rod to 200rpm, and the lateral movement speed to 0.4mm / sec, the printing time is 1min, after the preparation is completed, the receiving rod with the inner layer of the artificial blood vess...
Embodiment 3
[0017] Embodiment 3: polylactide (PLA) three-layer artificial blood vessel preparation
[0018]Preparation of artificial blood vessel inner layer: Weigh 1.2g PLA and add it into 10ml dichloromethane, stir and dissolve overnight at room temperature to prepare a PLA solution with a concentration fraction of 12% (mass / volume). The inner layer of the artificial blood vessel was prepared by direct printing in a fume hood at room temperature. Install the 4.0mm diameter stainless steel receiving rod on the printer. Inhale the PLA solution into the syringe and install it on the syringe pump. Place the needle of the syringe at a distance of 3.0mm above the metal receiving rod, set the advancing speed of the syringe pump to 3ml / h, the rotating speed of the receiving rod to 200rpm, and the lateral movement speed to 0.4mm / sec, the printing time is 1min, after the preparation is completed, the receiving rod with the inner layer of the artificial blood vessel is vacuum-dried.
