s3: the pressure detection unit detects the pressure inside the storage cylinder (13), and when the pressure is smaller than or larger than a reference value of the pressure, the pressure regulation unit is automatically started to regulate the pressure inside the storage cylinder (13);
s4: when the pressure of the storage cylinder (13) is judged to be rapidly reduced according to signals transmitted by the pressure sensor, the pressure alarm unit is automatically started to alarm, and when the liquid level sensor detects that physiological saline solution exists in the storage cylinder (13), the leakage alarm unit is triggered.
9. The syringe storage device with the spiral pressure regulating function according to claim 8, wherein: the step S1 further includes the steps of:
a1: the syringe is filled with normal saline to block the needle head of the syringe, so that the normal saline in the syringe is prevented from flowing out under the action of high pressure, the normal saline can also have a certain cleaning effect, and then the syringe is placed into a sterile storage cylinder (13);
a2: parameters such as wall thickness, height and material of the injector are input into the system, so that the subsequent calculation of the reference value of the pressure intensity is facilitated.
10. The syringe storage device with the spiral pressure regulating function according to claim 9, wherein: the method for calculating the pressure reference value in step S2 includes:
in the formula: p is a reference value of the pressure, T is the temperature inside the storage cylinder (13), TOften timesIs standard room temperature, d is the wall thickness of the syringe, h is the height of the syringe, h1Delta is the coefficient of compression resistance of the material used for the syringe, based on the height of the base.
