[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] Taking healthy New Zealand big-eared white rabbits with a body weight of 2.0-2.5kg as the test object, the method for making the rabbit pulmonary blood vessel model is as follows:
[0030] 1) Prepare the skin at the marginal ear vein of the rabbit, then inject 10mL of air along the marginal ear vein, and kill the rabbit;
[0031] 2) Use a scalpel to dissect the rabbit along the midline, and keep the rabbit lung and heart tissue;
[0032] 3) Flush the excess blood with 0.9% normal saline until the lung and heart tissue turns light red;
[0033] 4) Place the lung and heart tissue on the tray, select the gel pen refill for the catheter, rinse the ink in the pen, insert it into the superior vena cava, aorta, and main bronchus respectively, and use medical sutures to ligate and fix it respectively. Such as figure 1 shown;
[0034] 5) Select 30g of denture base ...
