[0153] If the comparison matches, it means that the identity of the test tube sample 9 has been successfully verified;

[0154] If the comparison does not match, it means that the test tube specimen 9 is missing or missing, and the medical staff is reminded to re-collect the body fluid sample of the corresponding patient;

[0155] In this embodiment, after the identity of the comparison unit is verified, the activation unit is triggered to activate the sensing unit and the dose analysis unit, and the dose of the test tube specimen obtained by analysis is bound to the patient's identity;

[0165] The posture evaluation unit obtains the acceleration data of the three spatial axes measured by the accelerometer, and calculates the tilt index Angle according to the following formula:

[0166]

[0167] In the formula, a x is the acceleration component of the accelerometer on the X-axis, a y is the acceleration component of the accelerometer on the Y axis, a z is the acceleration component of the accelerometer on the Z axis;

[0168] If the tilt index Angle exceeds the deviation threshold safety allowed by the system setting, the interaction unit is triggered to prompt the administrator;

[0169] If the tilt index Angle is lower than the allowed deviation threshold safety set by the system, it means that the tilt angle of the test tube specimen 9 stored in the storage component is within a safe range, and there is no need to prompt the manager;

[0170] The system setting allows the deviation threshold safety to be set by the system or the administrator according to the actual situation. This is a technical means well known to those skilled in the art. Those skilled in the art can refer to relevant technical manuals to learn about the technology, so it will not be described in detail in this embodiment.

[0172] In this embodiment, the interaction unit may be disposed on the handle 3 of the storage box 1 or at a position that can be directly observed or released by the carrier or administrator;

[0173] Through the mutual cooperation between the safety monitoring module and the storage module, the stored test tube specimens 9 can be made safer, and the test tube specimens 9 can be prevented from spilling due to excessive tilting during storage or transportation, thereby ensuring that the entire system has the advantages of strong protection capability, good protection effect, high intelligence, and good specimen storage management effect.
