7. A syringe storage unit having a screw pressure regulating function as claimed in claim 6, wherein: the step S1 further includes the steps of:
a1: filling physiological saline into the syringe, blocking the needle head of the syringe, avoiding the physiological saline in the syringe from flowing out under the action of high pressure, and enabling the physiological saline to have a certain cleaning effect, and then placing the syringe into a sterile storage cylinder (13);
a2: the wall thickness, the height and the material parameters of the injector are input into the system, so that the subsequent calculation of the reference value of the pressure intensity is facilitated.
8. A syringe storage unit having a screw pressure regulating function as claimed in claim 7, wherein: the method for calculating the pressure reference value in the step S2 comprises the following steps:
wherein: p is the reference value of pressure, T is the temperature inside the storage cylinder (13), T Often times Is at standard room temperature, d is the wall thickness of the syringe, h is the height of the syringe, h 1 As a function of the base height of the device,the compression resistance coefficient of the material used for the syringe.
