Description

Technical Field

[0001] The present invention belongs to the field of medical information technology, and in particular to an anesthetic medication management system with biometric recognition. Background Art

[0002] In modern medical practice, the management and control of anesthetic drugs relies on the experience and manual operation of doctors or anesthesiologists. The depth of anesthesia is usually regulated by manually adjusting the infusion rate and monitoring the patient's vital signs. Traditional anesthesia management systems mostly use basic monitoring equipment to monitor parameters such as blood pressure, heart rate, and oxygen saturation in real time. However, there are still many shortcomings in terms of drug safety and precise control of anesthesia depth.

[0003] First, the existing anesthetic drug management lacks an effective identity authentication mechanism, and mostly uses methods such as password input or fingerprint recognition, which are prone to identity information leakage or misidentification. It cannot meet the high security requirements for accurate identity verification of medical staff and patients during anesthesia operations, and it is difficult to effectively avoid medication errors caused by unauthorized operations or confusion of patient identities. Secondly, the assessment of anesthesia depth relies on a single parameter, fails to comprehensively consider the synergistic effects of EEG characteristics and hemodynamic parameters, and cannot fully reflect the patient's true anesthesia state, resulting in delayed or excessive medication adjustments and a large fluctuation range in anesthesia depth, affecting anesthesia quality and patient safety.

[0004] In addition, the medication decision-making process relies on manual adjustments by medical staff based on experience, and lacks an intelligent decision-making mechanism based on optimization algorithms. This not only increases the workload of medical staff, but also has low decision-making efficiency and is difficult to adapt to the rapid changes in patient status during surgery. Moreover, the safety protection mechanism of the existing system is mostly post-alarm, lacking real-time dynamic monitoring and active intervention of parameters such as drug dosage and patient vital signs. When drug overdose or abnormal patient vital signs occur, the medication operation cannot be frozen in time, posing a major safety hazard.

[0005] To this end, technicians in this field have proposed an anesthetic drug management system with biometrics, aiming to achieve precise and stable anesthesia depth control, thereby improving anesthesia safety and management efficiency, reducing operational errors and potential risks, and providing patients with a safer and more comfortable medical experience.

[0052] Figure 2 This is a flowchart of the anesthesia depth assessment unit of the present invention. DETAILED DESCRIPTION

[0053] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

By predicting the concentration changes and effects of drugs in patients, it can achieve personalized simulation of drug metabolism and improve the accuracy of medication prediction.

[0064] The decision algorithm unit is used to generate drug adjustment instructions based on preset rules and algorithms, combined with electronic anesthesia prescriptions, anesthesia depth assessment results and personalized drug metabolism and effect models, and preset safety boundary parameters.

[0065] As attached Figure 2 As shown, the anesthetic depth assessment unit also includes:

[0066] The EEG features were extracted based on the bispectral index and entropy index, and the EEG anesthesia index (AEI) was calculated using the following formula: t :

[0067]

[0068] Among them, B t is the bispectral index, the lower threshold is 40, the effective interval is [40,100], then the effective interval span is 60, E t Entropy index, its cutoff value is 90, the upper limit of the range is 100, ω1 and ω2 are the weight coefficients corresponding to the bispectral index and entropy index respectively;

[0070]

[0071] Among them, MAP t is the current mean arterial pressure, MAP base is baseline mean arterial pressure, HRV t is the current heart rate variability, HRV base is the baseline heart rate variability, λ is the blood pressure deviation penalty coefficient;

[0072] According to the AEI t and Circulation Stability Index (CSI) t , use the following formula to comprehensively assess the patient's anesthesia depth:

[0074] Among them, ADS tis the anesthesia depth assessment result, α and β are the weight coefficients corresponding to the EEG anesthesia index and circulatory stability index, respectively.

[0075] Taking the electronic anesthesia prescription as the initial benchmark, combined with the real-time anesthesia depth assessment results and the personalized drug metabolism and effect model, at each time step t, the optimal infusion rate sequence u(t),u(t+1),...,u(t+N-1) is obtained by solving the following optimization problem:

[0076]

[0077] Among them, E target is the target anesthesia depth obtained by electronic anesthesia prescription, ADS(t+k|t) is the future anesthesia depth predicted based on the information at time t, N is the prediction time domain, u(t) is the infusion rate at time t, represents the minimization of infusion rate variations, is the weight factor, k is the future time offset starting from time t;

[0085] The decision algorithm unit also presets safety boundary parameters, including upper and lower limits of drug dosage, dangerous thresholds of patient vital signs, and safe range of equipment operating parameters. When multi-source data reaches the safety boundary parameters, an early warning signal is generated and the current medication operation is frozen.

[0086] By solving optimization problems, the optimal infusion rate is obtained, and instructions for adding, reducing, or changing medications are generated. At the same time, when the data reaches the safety boundary, an early warning is issued and the operation is frozen, achieving accurate and safe medication adjustments.

[0087] The execution control module is used to send the drug adjustment instruction to the anesthetic drug infusion device for execution after the drug adjustment instruction is confirmed by biometric identification. The execution control module establishes a two-way communication connection with the anesthetic drug infusion device such as the intravenous infusion pump, micro-injection pump, and inhalation anesthesia machine, and also includes:

[0088] After receiving the medication adjustment instruction, the identity of the operating medical staff is verified through the biometric module;

[0089] According to the verified drug adjustment instructions, the anesthetic drug infusion device is controlled to perform dosage adjustment, infusion rate change or drug switching operations, and the infusion status data of the intelligent infusion pump is updated synchronously.

[0090] The drug adjustment instruction is sent to the anesthetic drug infusion device for execution after biometric secondary confirmation, and the infusion status data is updated to ensure the accurate execution of the medication instruction. The secondary identity verification further guarantees the operation safety, synchronizes the device status in real time, and realizes the closed-loop control of the medication process.

[0091] Example 2: This example is basically the same as the previous example, except that it further includes a human-computer interaction module, which is configured as follows:

[0092] Displays patients' real-time vital signs, anesthesia depth assessment results, electronic anesthesia prescriptions, and medication adjustment suggestions;

[0093] Receive manual intervention instructions from medical staff after biometric verification, and their manual intervention instructions take precedence over medication adjustment instructions generated by the decision-making module;

[0094] Record all medication operation logs and biometric verification information to form a traceable electronic audit trail.
