collection consumable is lower than a preset threshold, the system maintains the blocking state, and sends out an error prompt (such as continuous short beep) through the sense prompt component, the blood collection execution component is always kept mechanically locked and cannot perform blood collection operation, after the system enters a pre-authorized state, an operator slowly approaches the needle point of the blood collection execution component to a biological body surface (such as a macromolecule bionic skin model), the near field communication reading module continuously monitors the characteristic change of the coil load impedance, when the near field communication reading module detects that the distance between the needle point of the blood collection execution component and the biological body surface meets a millimeter-level distance condition for the first time (such as,) When the situation sensing processor immediately controls the electromagnetic driving lock pin to unlock the blood taking executing component so as to carry out one-time operation authorization on the blood taking executing component, at the moment, the sensory prompting component outputs an unlocking prompt, if the situation sensing processor exceeds a fixed effective time window (for example, 8 seconds) and still does not meet millimeter-level distance conditions under the pre-authorization state, or an operator moves the blood taking equipment away from the surface of a living body, the situation sensing processor automatically resumes the locking of the electromagnetic driving lock pin to the blood taking executing component and outputs an authorization timeout prompt, when the blood taking executing component is under the execution authorization state, the situation sensing processor simulates the operator to complete the blood taking action, judges that the blood taking action is completed by monitoring the stroke, the speed and the

In embodiment 4, the intelligent blocking type blood sampling safety control system and method based on identity verification interlocking are described with reference to fig. 1 to 4, as shown in fig. 1, firstly, an operator approaches the system, and synchronously reads the identity information of a patient and the identification of blood sampling consumable materials through a context sensing processor, the context sensing processor verifies the logic consistency of the identity information of the patient and the identification information of the consumable materials according to a matching rule, after the verification is passed, the system acquires entity characteristic data, and confirms the authenticity of the blood sampling consumable materials through the comparison of a near-field communication module and electromagnetic interaction characteristics, then, the system enters a pre-authorization state and sends out an authorization success prompt tone, the operator approaches a needle point to a millimeter-level distance from the surface of an organism, at the moment, the system monitors and releases a lock pin, sends out an unlocking prompt tone, and after the blood sampling action is completed, the system resumes locking and sends out a completion prompt tone.
As shown in FIG. 2, the horizontal axis in the graph represents time window (seconds) and the vertical axis represents system performance index (percentage), the four curves represent different performance indexes, namely operation success rate (solid circle mark), safety score (broken triangle mark), user satisfaction (broken square mark) and recommended value (broken diamond mark), as the time window increases, the operation success rate is gradually improved and tends to be stable, the safety score and the user satisfaction show certain fluctuation along with the increase of the time window, but the general trend is still upward, the recommended value is changed similarly to the operation success rate, the recommended value is closely related to the system performance, the graph reflects that the system performance is obviously improved along with the increase of the operation time, and the safety and the user experience are optimized.
As shown in fig. 3, the system synchronously receives and judges the logic consistency of three input information from the unique patient identity identifier, the unique consumable identity identifier and the operator identity identifier through the context-aware processor, the context-aware processor judges the matching rule based on the associated blood sampling task information on one hand, and performs entity consistency verification by combining the entity characteristic reference data on the other hand to ensure the physical authenticity of the blood sampling consumable, if the result of the judgment is matching, the context-aware processor triggers a lock pin releasing instruction so as to control the electromagnetic drive lock pin to release the locking of the blood sampling execution component, and if the judgment is not matching, the system maintains a locking state to prevent the subsequent operation.
As shown in FIG. 4, the graph takes the distance between the needle tip and the skin as a variable, the unit is millimeter (mm), the distance is reduced from 10mm to 0mm, the approaching distance of the blood sampling execution part in each stage in the process of approaching the skin is reflected, the unit is the detection accuracy, the unit is percentage (%), the distribution is from 10% to 100%, the recognition accuracy of the system to the state of approaching the needle tip to the skin is reflected, three detection curves representing different skin models are drawn in the graph, namely a standard skin model (solid line circle mark), a thick stratum corneum model (dotted line square mark) and a thin skin model (dot-line triangle mark), and the detection accuracy of the three models all shows an ascending trend as the distance between the needle tip and the skin is gradually reduced, particularly the thin skin model ascends most rapidly and reaches more than 80% within 4mm, and the whole thick stratum corneum model is slightly lower, so that the system has certain adaptability to different skin types.
Meanwhile, in the process of generating and comparing entity characteristic data, the dielectric properties of a rubber plug and the material of a vacuum tube are not directly involved in data processing by material names, but are indirectly reflected as response changes generated by the distribution of an antenna electromagnetic field by a carrier through the electromagnetic coupling characteristics of a near field communication reading module, when a near field communication tag is attached to different physical carriers, the local electromagnetic environment where the tag body is positioned is subjected to weak but measurable differences, and the entity characteristic data is the structural representation of a plurality of electrical parameters such as equivalent load impedance, coupling factors, resonant frequency fine tuning and the like of an antenna coil, wherein the entity characteristic data is the multi-dimensional original measurement results which are acquired by a reading module in the standard communication handshake process, and the core aim is to establish a traceable mapping path between a physical entity structure, namely dielectric interference, electromagnetic response, parameter disturbance and characteristic vector; and rubber stopper dielectric property or vacuum tube material are macroscopically consistent, but under millimeter space scale, the vacuum tube material is extremely sensitive to interference mode of near field high frequency magnetic field, for example, when silica gel, butyl rubber or multi-layer composite package is close to an antenna structure, equivalent inductance or circuit Q value can generate disturbance with the magnitude between micro ohm and tens of micro ohm, and in the same way, vacuum blood collection tubes with different wall thickness or surface coating can cause offset of dielectric resonance point due to shielding effect on coupling medium of label bottom layer, therefore, even if two labels are completely consistent in data layer, as long as there is microcosmic difference of attached entity structure, the collected entity characteristic data can also present distinguishable distribution characteristic in multidimensional characteristic space, the stored reference feature data is just based on that a plurality of historical batch blood sampling consumables are subjected to standardized attachment and reading conditions, a similarity threshold value is set through a representative entity response data set acquired, encoded and normalized by a near field communication module, only a data sample falling into a specified similarity confidence interval in the feature space is allowed to be regarded as a physical entity to be truly effective, and therefore systematic endogenetic verification of physical consistency of the blood sampling consumables is achieved on the premise that a radio frequency sensor or an optical detection component is not required to be additionally added, and the method belongs to an extension implementation mode known by a person of ordinary skill in the art.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
Finally, it should be noted that the above-mentioned embodiments are merely for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
