Description

Technical Field

[0001] This invention relates to the field of smart wristbands, and more particularly to a smart wristband data synchronization method and system for preoperative safety checks. Background Technology

[0002] In the medical field, preoperative safety checks are a crucial step in ensuring patient surgical safety and preventing medical errors. However, with the continuous advancement of medical information technology, traditional preoperative safety check methods have gradually revealed numerous problems, making it difficult to meet the demands of modern medicine for efficiency, precision, and safety.

[0003] Traditional preoperative safety checks rely primarily on manual procedures, with medical staff verifying patient identity and surgical information through verbal inquiries and comparison of paper medical records. This method is not only inefficient and time-consuming, but also prone to human error and oversight. Fatigue or lack of concentration among medical staff can lead to inaccurate information verification, potentially resulting in serious medical accidents such as incorrect surgical sites or patient identity confusion.

[0004] Traditional verification methods lack effective data recording and traceability mechanisms. Once a medical error occurs, it is difficult to quickly and accurately identify the root cause, failing to provide strong evidentiary support for handling medical disputes. Furthermore, during patient transfer, the lack of real-time information exchange and monitoring means cannot ensure that patients are transferred to the operating room at the correct time and according to the correct procedures, increasing surgical risks.

[0005] The existing preoperative safety check process requires medical staff to manually perform multiple steps, which is cumbersome and prone to human error and oversight. Furthermore, the lack of an automated verification mechanism prevents real-time multi-party verification, resulting in low efficiency and hindering the smooth progress of the surgery.

[0006] In unforeseen circumstances such as wristband reading failure, current technology lacks an effective emergency response mechanism, making it impossible to obtain the patient's core information in a timely manner to ensure the continuation of the surgery. Furthermore, the issues of post-emergency recovery and data synchronization remain unresolved, potentially impacting subsequent medical procedures.

[0007] Therefore, we propose a smart wristband data synchronization method and system for preoperative safety checks to address the above issues. Summary of the Invention

[0008] This invention provides a smart wristband data synchronization method and system for preoperative safety checks, which improves the accuracy of preoperative safety checks.

[0009] The first aspect of this invention provides a smart wristband data synchronization method for preoperative safety verification, the smart wristband data synchronization method for preoperative safety verification comprising: 1. a smart wristband data synchronization method for preoperative safety verification, characterized in that it is applied to a system including a wristband, a ward reader / writer, a transport reader / writer, and an operating room reader / writer, the smart wristband data synchronization method for preoperative safety verification comprising: The ward reader generates a first synchronization instruction including patient identity information, medical information and planned surgery information, and writes the first synchronization instruction into the storage chip of the wristband, so that the wristband enters the initialized state; During patient transport, the transport reader reads the wristband data in the initialized state, generates a transport verification record, and writes the transport verification record into the wristband, thus putting the wristband into the transport confirmation state. The operating room reader reads the data of wristbands in the transfer confirmation state at the entrance of the operating room and compares it with the surgical scheduling data to generate a surgical checklist. Before the surgical incision, the wristband is read to obtain the surgical checklist for joint verification. The handheld reading and writing device writes the confirmation result of the verification to the wristband, putting the wristband into a surgical ready state to authorize the start of the surgery.

[0010] Optionally, in a first implementation of the first aspect of the present invention, the method includes: obtaining a patient's identity data packet, medical data packet, and surgical plan data packet from a hospital information system; constructing a hierarchical data writing structure based on the identity data packet, medical data packet, and surgical plan data packet; the hierarchical data writing structure includes at least a read-only information layer that cannot be changed after writing, and an updatable information layer that allows verification information to be appended in subsequent processes; calculating and setting a data validity time window based on the current system time and the planned surgical time in the surgical plan data packet; encapsulating the hierarchical data writing structure, the data validity time window, and the ward terminal identifier representing the data source into a first synchronization instruction; writing different data layers in the first synchronization instruction into the corresponding physical storage blocks of the wristband storage chip, and performing readback verification on the data of each block after writing to generate a block write verification result; when the block write verification results of all physical storage blocks indicate that the data is complete, the ward reader writes a synchronization status flag representing the completion of initialization to the wristband, causing the wristband to enter the initialized state, which is subsequently read by the transport reader to determine whether to perform transport verification.

[0011] Optionally, in a second implementation of the first aspect of the present invention, the method includes: when the transport reader detects a wristband in the initialized state within its sensing range, reading all data of the wristband and generating a wristband data copy; obtaining the current system time and location identifier of the transport reader, and combining it with the wristband data copy to generate a verification factor; matching and verifying the verification factor with the pre-loaded patient transport task sheet to generate a matching verification result; when the matching verification result is a successful match, combining the verification factor and the matching verification result to form a transport verification record; appending the transport verification record to the verification log storage area specified by the wristband in a non-contact manner, and overwriting the synchronization status marker of the wristband, updating it to a transport confirmation status marker indicating the completion of the transport, thereby enabling the wristband to enter a transport confirmation state, which is subsequently used by the operating room reader as an admission condition for comparison.

[0012] Optionally, in a third implementation of the first aspect of the present invention, the transfer validity determination value is calculated using a matching logic formula. To ensure that patients are transferred within the correct time window: ; in, This is an indicator function; it is 1 when the wristband ID matches the task ID, and 0 otherwise. It is a step function; To schedule the surgery; The maximum allowable lead time for transit as preset by the system; Patient wristband ID; This is the transfer task order ID.

[0013] Optionally, in the fourth implementation of the first aspect of the present invention, if the matching verification result is a failure alarm, a transfer anomaly handling process is triggered: the cause of the failure alarm is analyzed, and an anomaly type identifier is generated, the anomaly type identifier including at least task order mismatch, patient identity doubt, or wristband data failure; according to the anomaly type identifier, a corresponding one is selected and activated from a variety of preset supplementary verification strategies; the activated supplementary verification strategy is executed, supplementary verification information is obtained, and it is compared again with the wristband data copy and the transfer task order to generate a supplementary verification result; if the supplementary verification result is successful, the supplementary verification result together with the anomaly type identifier is encapsulated into a supplementary verification record; the supplementary verification record is written into the verification log storage area of ​​the wristband, and the wristband status marker is updated accordingly to make it enter the transfer confirmation state.

[0014] Optionally, in a fifth implementation of the first aspect of the present invention, the method includes: the operating room reader reading all data of the wristband in the transfer confirmation state, and extracting the transfer verification record from the verification log storage area of ​​the wristband to generate a wristband data summary; obtaining the patient identity, surgery name, and surgical site information currently scheduled in the operating room from the surgical scheduling system to generate real-time surgical scheduling data; performing a multi-dimensional comparison between the patient identity and surgical information in the wristband data summary and the real-time surgical scheduling data to generate a difference comparison report; comparing the time information in the transfer verification record with a preset valid time threshold to verify the timeliness of the wristband data and generate a data timeliness status; verifying the continuity of the signature or verification chain of the data storage block during the process of writing to reading the wristband data to generate a data integrity status; and combining the difference comparison report, the data timeliness status, and the data integrity status to generate a surgical checklist.

[0015] Optionally, in the sixth implementation of the first aspect of the present invention, the following steps are included: the surgeon, anesthesiologist, and circulating nurse each use their respective handheld reading and writing devices to sequentially read the wristband and obtain a surgical checklist; each medical staff member independently confirms each item on the surgical checklist on their respective handheld reading and writing device, generating an independent confirmation signal; any one of the handheld reading and writing devices acts as a verification coordination node, receiving the independent confirmation signals sent from other handheld reading and writing devices, and converging all received independent confirmation signals with its own generated independent confirmation signal to generate a joint verification result; when the joint verification result shows that all required confirmation items have been independently confirmed by the three parties without error, the verification coordination node generates a verification pass instruction; the verification coordination node writes the verification pass instruction and the complete joint verification result as a surgical authorization marker into a designated state storage area of ​​the wristband, overwriting the previous state marker, so that the wristband enters a surgical ready state; the surgical ready state serves as a unique electronic credential for subsequent surgical equipment or recording systems to verify permissions before performing critical operations.

[0016] Optionally, in the seventh implementation of the first aspect of the present invention, an emergency verification process is triggered when any reading / writing device fails to read the wristband in a non-contact manner: the optical scanning unit of the handheld reading / writing device scans the visually encoded pattern printed on the surface of the wristband and decodes it to obtain core verification data; the handheld reading / writing device compares the core verification data with the scheduling data in the current operating room system to generate an emergency verification result; if the emergency verification result passes, the handheld reading / writing device generates an emergency verification certificate with a time limit; the emergency verification certificate is displayed on the screen of the handheld reading / writing device for the surgical team to verify and confirm; the emergency verification result and the generation record of the emergency verification certificate are uploaded to the operating room backend system to form an emergency verification log.

[0017] Optionally, in the eighth implementation of the first aspect of the present invention, after the emergency verification process is completed, a status recovery and record synchronization process is executed: the communication link status between the handheld reading and writing device and the wristband is monitored, and a communication recovery signal is generated when the communication link is detected to be available again; in response to the communication recovery signal, the handheld reading and writing device encapsulates the key confirmation information in the emergency verification log into a status update instruction; the status update instruction is written to the wristband to overwrite the previous status marker of the wristband, so that it is updated to the surgical ready state corresponding to the emergency verification result, and the physical state of the wristband is repaired; the handheld reading and writing device associates and binds the writing result of the status update instruction with the locally stored emergency verification log to generate a complete verification record; the complete verification record is uploaded to the operating room backend system to replace or supplement the previously uploaded emergency verification log to form a continuous surgical verification file.

[0018] A second aspect of this invention provides an intelligent wristband data synchronization system for preoperative safety verification. The system includes: an information module for the ward reader to generate a first synchronization instruction including patient identity information, medical information, and planned surgery information, and to write the first synchronization instruction into the wristband's storage chip, thus putting the wristband into an initialized state; a transport module for the transport reader to read the wristband data in the initialized state during patient transport, generate a transport verification record, and write the transport verification record into the wristband, thus putting the wristband into a transport confirmation state; a verification module for the operating room reader to read the wristband data in the transport confirmation state at the operating room entrance, compare it with surgical scheduling data, and generate a surgical verification list; and an authorization module for reading the wristband before surgical incision, obtaining the surgical verification list for joint verification, and having the handheld reader write the verification result into the wristband, thus putting the wristband into a surgical ready state to authorize the commencement of surgery.

[0019] Optionally, in a second implementation of the second aspect of the present invention, an emergency module is further included, which is used to trigger an emergency verification process when any reading / writing device fails to read the wristband in a contactless manner.

[0020] The mechanism of this invention is as follows: by using a wristband as a mobile data carrier rather than a simple identifier, patient information evolves synchronously with physical movement, thus solving the problem of information gaps. Beneficial effects: Setting a valid data time window, calculated and set according to system time and planned surgery time, ensures that wristband data is used within the valid time, avoids verification errors caused by expired data, improves the timeliness and reliability of data, and makes preoperative verification more scientific and reasonable; The transport reader combines wristband data, its own system time and location identifier to generate verification factors, and matches and verifies them with the pre-loaded transport task sheet. In this way, the legality and accuracy of patient transport are accurately confirmed, effectively preventing patient transport errors and ensuring patient safety during the transport process. By using matching logic formulas to calculate the validity value of patient transfer, the patient transfer is strictly controlled from the time dimension, ensuring that the patient is transferred to the operating room within the correct time window, which further reduces the risk of the transfer process and improves the standardization and safety of the entire medical process. When the matching verification fails, the system can quickly analyze the reason and select the corresponding supplementary verification strategy. It obtains supplementary verification information by comparing again. If it passes, it updates the wristband status to put it into the transfer confirmation status, providing an effective solution for possible problems during the transfer process. This avoids surgical delays or errors caused by abnormal transfer, and enhances the system's fault tolerance and stability. After the emergency verification process is completed, the system can monitor the status of the communication link. When it is restored to availability, the system encapsulates the key confirmation information in the emergency verification log into a status update instruction and writes it to the wristband. The wristband status is updated and a complete verification record is generated and uploaded to the backend system, ensuring the timely repair of the wristband status and the continuity of data recording, and providing complete archival support for subsequent medical operations and traceability.

[0022] This invention provides a smart wristband data synchronization method and system for preoperative safety checks, improving the accuracy of preoperative safety checks. The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0023] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1The smart wristband data synchronization method for preoperative safety verification in this invention is applied to a system including wristbands, ward readers, transport readers, and operating room readers. Examples include: 101. The ward reader generates a first synchronization command including patient identity information, medical information and planned surgery information, and writes the first synchronization command into the storage chip of the wristband in a non-contact manner, so that the wristband enters the initialized state. It is understood that the executing entity of this invention can be a smart wristband data synchronization system for preoperative safety verification, or it can be a terminal or a server; the specific implementation is not limited here. This embodiment of the invention will be described using a server as an example.

[0024] It should be noted that the patient, Mr. Zhang, needed emergency surgery for chronic appendicitis. In the inpatient ward, the nurse used a ward reader to initialize the wristband he was wearing.

[0025] The nurse entered or confirmed the following information for Mr. Zhang in the ward's computer system: Identification Information: Name "Zhang", Gender "Male", Age "45 years old", Medical Record Number "P20241120015", ID Number "31010119790101XXXX". Medical Information: Preliminary Diagnosis "Acute Appendicitis", Allergy History "Penicillin Allergy", Blood Type "O Rh Positive", Recent Vital Signs (Temperature "37.8℃"). Planned Surgery Information: Surgery Name "Laparoscopic Appendectomy", Scheduled Operating Room "Operating Room 3", Surgeon "Director Li", Anesthesia Method "General Anesthesia", Planned Surgery Time "December 10, 2025, 09:30". This information was then integrated to generate a structured "First Synchronization Instruction". The instruction may include not only the data mentioned above, but also the timestamp "2025-12-10 08:00:00", the operator (nurse ID "N202412"), and a checksum (to ensure data integrity).

[0026] The nurse brings a brand-new wristband close to the reader (usually within 5-10 centimeters). The wristband has a built-in RFID chip (a high-frequency chip conforming to the ISO15693 standard) or a similar contactless storage chip. It does not require a built-in battery and obtains power from the radio frequency signal emitted by the reader's antenna to complete communication.

[0027] The ward reader uses radio frequency signals to write all the data in the first synchronization command into the designated storage area of ​​the wristband chip in a non-contact manner. The entire process takes very little time (usually in the millisecond range). After successful writing, the reader may emit a beep or light up a green indicator to confirm. The wristband chip can be designed with multiple storage areas, each corresponding to different information blocks such as identity, medical, and surgical data, and appropriate access permissions can be set.

[0028] After the data is written, the system will write an "initialized" status value to a specific status flag on the wristband chip (changing the status flag from "00" inactive to "01" initialized). This means that the wristband has successfully loaded the patient's basic surgical information and is ready for subsequent transport. The nurse can use the reader again to check the wristband information to ensure that all data is accurate. The wristband display (if any) or reader interface will clearly display "Initialization Complete" or a similar message. At this point, the wristband officially enters the "initialized state," preparing for recognition and verification by the transport reader during the next stage of patient transport.

[0029] 102. During patient transport, the transport reader reads the data of the wristband in an initialized state in a non-contact manner, generates a transport verification record including the reading time and location, and writes the transport verification record into the wristband, so that the wristband enters the transport confirmation state. It should be noted that patient Zhang has completed wristband initialization and is scheduled to undergo a laparoscopic appendectomy at 9:00 AM on December 10, 2025. Transport nurse Li (employee number: N203802) used a handheld transport reader to perform the following operations: At 8:15 AM, Li, standing beside Zhang's bed, brought the transport reader close to Zhang's initialized wristband (approximately 5-10 cm away). The reader instantly (in milliseconds) read the data from the wristband chip using a non-contact method via a 13.56MHz high-frequency RFID signal. The data included: Patient identification information: Name "Zhang", Medical Record Number "P20241120015"; Medical information: Allergy history "Penicillin allergy", Blood type "O type Rh positive"; Planned surgery information: Surgery name "Laparoscopic appendectomy", Scheduled operating room "Operating Room 3".

[0030] The reader automatically generates a structured transport verification record. This record includes: Reading time: 2025-12-10 08:15:30; Reading location: automatically marked as "Room 302, Bed 1, General Surgery Ward, 9th Floor, East Wing, Inpatient Building" via the reader's built-in department location beacon or the hospital's indoor positioning system; Operator: automatically associated with the employee ID "N203802" of the logged-in nurse, Ms. Li. The core function of this record is to prove that the patient has been confirmed and transported by authorized personnel at a specific time and location.

[0031] After the record is generated, the transport reader encrypts and writes the complete transport verification record into a specific storage area ("transport log area") of the wristband chip through the same RFID channel. The entire process is completed within 1 second. Once the data is successfully written, the reader sends a command to the status flag bit of the wristband chip, updating it from "Initialized" (status value "01") to "Transport Confirmed" (status value "02"). The transport reader interface displays a message: "Transport record written successfully, wristband has entered transport confirmation state." Nurses can quickly verify the screen information to ensure the process is correct.

[0032] 103. The operating room reader reads the data of the wristband in the transfer confirmation state in a non-contact manner at the entrance of the operating room, compares it with the surgical scheduling data, and generates a surgical checklist. It should be noted that the following embodiment specifically illustrates the complete process of how the operating room reader reads the wristband data, compares it with the surgical scheduling information, and generates a surgical checklist when the patient arrives at the operating room entrance (corresponding to step 103). The scenario continues from the previous example: Patient Zhang needs to undergo a "laparoscopic appendectomy".

[0033] At 8:45 AM, patient Zhang was transported to the operating room entrance by the transfer nurse. Operating room nurse Wang (employee number: N203805) held an operating room reader close to Zhang's wristband (approximately 5-10 cm away). The reader, based on high-frequency RFID technology (13.56MHz), instantly reads data from the wristband chip via radio frequency signals. The read information included: Patient identification information: Name "Zhang", Medical Record Number "P20241120015", ID Number "31010119790101XXXX". Medical information: Allergy history "Penicillin allergy", Blood type "O type Rh positive". Transfer verification record: Transfer time "2025-12-10 08:15:30", Transfer origin "9th floor, East Wing, General Surgery Ward, Room 302, Bed 1" (generated from step 102). At the same time, the reader automatically checks whether the wristband status flag is in "transfer confirmation status" (status value "02") to ensure process continuity.

[0034] The reader connects to the hospital's intranet (Wi-Fi) in real time to the surgical scheduling system, retrieving scheduling data for the current operating room (in this example, "Operating Room 3"). The system compares key fields: Patient matching: The medical record number "P20241120015" on the wristband matches the patient's medical record number corresponding to "Operating Room 3, 09:30 surgery" in the scheduling system. Time and procedure verification: The planned surgery time "09:30", the surgery name "laparoscopic appendectomy", and the surgeon "Director Li" all match the schedule. Anomaly handling: If the scheduling data does not match the wristband information (operating room error or time conflict), the reader will immediately trigger an audible and visual alarm and prompt a nurse for manual verification.

[0035] After successful verification, the system automatically generates a structured surgical checklist, which is displayed on the reader screen. The checklist integrates wristband data and scheduling information, including the following core items: Patient identity verification: name, medical record number, last four digits of ID card (displayed de-identified). Medical safety information: allergic drugs (highlighting "Penicillin allergy"), blood type, preoperative fasting status ("Fasted for 8 hours"). Surgical details: surgery name, operating room number, planned incision time, anesthesia method (general anesthesia), list of required instruments (laparoscopic kit). Team information: names of the surgeon, anesthesiologist, and circulating nurse. Transfer closed-loop verification: displays "Transfer confirmed, origin: Ward 302, Bed 1, time: 08:15:30", ensuring traceable handover.

[0036] After the list is generated, the system automatically records the operation time "2025-12-10 08:46:00" and the nurse's employee number "N203805", and updates the wristband status to "pending verification" (status value "03"), in preparation for the final preoperative verification in step 104.

[0037] 104. Before the surgical incision, medical staff use a handheld reading and writing device to read the wristband in a non-contact manner and obtain the surgical checklist for joint verification. The handheld reading and writing device writes the verification result into the wristband, putting the wristband into the surgical ready state and authorizing the start of the surgery.

[0038] It should be noted that patient Zhang has entered operating room three and is about to undergo a laparoscopic appendectomy.

[0039] Preoperative final verification and preparation: At 9:20 AM, the surgeon, Dr. Li, the anesthesiologist, Dr. Zhao, and the circulating nurse, Ms. Wang, gathered at the operating table. Nurse Wang held a handheld reader / writer (a PDA or tablet with RFID functionality), which was connected to the surgical anesthesia system in real-time via the hospital's wireless network. Wristband data reading: The nurse brought the handheld device close to Zhang's wristband (approximately 5 cm away). The device instantly read the data from the wristband chip using high-frequency RFID technology (13.56MHz). The read information included: Patient identification information: name, medical record number, and ID number. Medical information: allergy history (highlighting "penicillin allergy"), blood type, and preoperative vital signs. Surgical verification checklist: generated in step 103, including the surgery name, operating room, anesthesia method, instrument list, and transport verification record (transport time and location). Status verification: The device automatically verified the wristband's current status as "pending verification" (status value "03"), ensuring process continuity.

[0040] The three parties jointly verify and confirm the checklist. The verification process is as follows: The structured surgery checklist is displayed on the handheld device screen (as shown in Table 1 below). The medical staff and nurses verify each item by voice and check the boxes to confirm. Table 1

[0041] Anomaly Handling: If any item does not match (incorrect surgery name), the device will trigger an audible and visual alarm and lock the next operation, requiring re-verification. In this example, all items passed verification, and all three parties electronically signed on the device (nurse's employee number "N203805", doctor's Ukey authentication).

[0042] Status Update and Surgical Authorization: After verification, the handheld device encrypts and writes the structured confirmation result into the wristband chip, including: Verification Time: 2025-12-10 09:22:00. Participants: Li (surgeon), Zhao (anesthesiologist), Wang (nurse). Verification Result: All items are consistent. Wristband Status Update: The device sends a command to the wristband status flag, updating it from "Pending Verification" (status value "03") to "Surgery Ready" (status value "04"). This status signifies the completion of the entire safety verification process, and the system automatically unlocks the surgical authorization (allowing anesthesia induction and power-on of the surgical instrument cart). Record Synchronization: The confirmation result is synchronized to the hospital information system in real time, generating an unalterable electronic verification record for medical quality traceability.

[0043] Please see Figures 2 to 5 In this embodiment of the invention, the smart wristband data synchronization method for preoperative safety verification is applied to a system including wristbands, ward readers, transport readers, and operating room readers. Another embodiment includes: 201. The ward reader generates a first synchronization command including patient identity information, medical information and planned surgery information, and writes the first synchronization command into the wristband's storage chip in a non-contact manner, so that the wristband enters the initialized state. Specifically, the ward reader obtains the patient's identity data packet, medical data packet, and surgical plan data packet from the hospital information system; based on the identity data packet, medical data packet, and surgical plan data packet, a hierarchical data writing structure is constructed; the hierarchical data writing structure includes at least a read-only information layer that cannot be changed after writing, and an updatable information layer that allows verification information to be appended in subsequent processes; based on the current system time and the planned surgery time in the surgical plan data packet, a data validity time window is calculated and set; the hierarchical data writing structure, the data validity time window, and the ward terminal identifier representing the data source are encapsulated together into a first synchronization instruction; different data layers in the first synchronization instruction are written into the corresponding physical storage blocks of the wristband storage chip through near-field communication, and the data in each block is read back and verified after writing to generate a block write verification result; when the block write verification results of all physical storage blocks indicate that the data is complete, the ward reader writes a synchronization status flag indicating that initialization is complete to the wristband, so that the wristband enters the initialized state; this initialized state is subsequently read by the transport reader to determine whether to perform transport verification.

[0044] It should be noted that the scene took place in the general surgery ward at 7:30 AM. The nurse in charge was holding a ward reader / writer (model H-RDR-V3) and preparing to initialize the wristband for patient Zhang in bed 5, who was about to undergo laparoscopic cholecystectomy.

[0045] The ward reader connects to the hospital information system (HIS) via a wireless network. After a nurse scans a patient's bedside card, the reader automatically captures the following three core data packets: Identity data package: contains patient name "Zhang", hospital number "2023102505", gender "male", and age "45 years old".

[0046] Medical data package: includes blood type "A", allergy history "penicillin allergy (high-risk red mark)" and past medical history "hypertension".

[0047] Surgical plan data package: includes the name of the surgery "Laparoscopic cholecystectomy", the side of the surgery "None", the chief surgeon "Director Li", and the planned start time "2023-10-25 09:00".

[0048] The internal processor of the reader reorganizes the above information into a hierarchical data writing structure: Read-only information layer (locked area): mapped to sectors 4 to 8 of the wristband chip's storage area. This layer encapsulates the patient's identity (Zhang, hospital number) and key medical warnings (penicillin allergy). This data is locked after being written to prevent subsequent tampering. Updatable information layer (open area): mapped to sectors 9 to 12. This layer is initialized to a blank format, with reserved slots for "transfer verification" and "operating room check-in".

[0049] The time window and instruction encapsulation are set. The reader reads the current system time as 07:30 and combines it with the planned surgery time of 09:00. Using a built-in algorithm, the effective time window for the data is calculated to be "07:30 to 15:00" (covering preoperative preparation and the estimated surgery duration). Subsequently, the reader packages the above-mentioned layered data, time window, and local device code "WARD-SURG-03" together to generate the first synchronization instruction.

[0050] Write and readback verification: The nurse brings the reader close to the passive smart wristband (less than 5 cm away). The reader activates the wristband chip via a high-frequency signal: writing read-only data to sectors 4-8 and writing blank templates to sectors 9-12. Readback verification: After the write operation is completed, the reader immediately sends a read signal to read data from sector 4 of the wristband and performs a bit-level comparison with "Zhang Mou" in memory. If the comparison matches, the screen displays "Block write verification passed".

[0051] After confirming that all data sectors have been written correctly, the reader writes a specific hexadecimal status code to the wristband's status control area (sector 3), which represents "initialized status". At this time, the wristband screen or reader interface displays "Initialization successful, awaiting transfer". At this point, the wristband is electronically qualified to be recognized by the subsequent transfer reader, and its internal data is valid until 15:00, completing the transformation from an ordinary wristband to a pre-operative safety verification smart terminal.

[0052] 202. During patient transport, the transport reader reads the data of the wristband in an initialized state in a non-contact manner, generates a transport verification record including the reading time and location, and writes the transport verification record into the wristband, so that the wristband enters the transport confirmation state. Specifically, when the transport reader detects an initialized wristband within its sensing range, it reads all the data from the wristband and generates a data copy. It then obtains the current system time and location identifier of the transport reader and, combined with the wristband data copy, generates a verification factor. The verification factor is then matched against the pre-loaded patient transport task sheet to generate a matching verification result. The matching verification result includes a successful match or a failure alarm. When the matching verification result is a successful match, the verification factor and the matching verification result are combined to form a transport verification record. This transport verification record is appended to the designated verification log storage area of ​​the wristband in a contactless manner, overwriting the wristband's synchronization status marker and updating it to a transport confirmation status marker indicating the completion of the transport, thus putting the wristband into a transport confirmation state. This transport confirmation state is subsequently used by the operating room reader as an entry condition for comparison.

[0053] Furthermore, if the matching verification result is a failure alarm, the transfer anomaly handling process is triggered. The transfer anomaly handling process includes: analyzing the reason for the failure alarm and generating an anomaly type identifier; the anomaly type identifier includes at least task order mismatch, questionable patient identity, or wristband data failure; selecting and activating one of the preset supplementary verification strategies based on the anomaly type identifier; the supplementary verification strategies include obtaining information by scanning the QR code attached to the wristband or having the transfer personnel manually enter the verification code; executing the activated supplementary verification strategy, obtaining supplementary verification information, and comparing it again with the wristband data copy and the transfer task order to generate a supplementary verification result; if the supplementary verification result is successful, the supplementary verification result, together with the anomaly type identifier, is packaged into a supplementary verification record; the supplementary verification record is written to the verification log storage area of ​​the wristband in a contactless manner, and the wristband status marker is updated accordingly to put it into the transfer confirmation state.

[0054] It should be noted that the implementation time was advanced to 08:40 AM (the scheduled surgery time was 09:00 AM). Operating room transport worker Wang pushed a trolley, transporting patient Zhang, in bed 5, to the dedicated operating room elevator lobby. At this time, Wang used a T-PAD-Pro transport reader to perform the crucial "out-of-area-in-area" transfer verification on the patient's wristband.

[0055] Wristband Detection and Data Copy Generation: When the trolley enters the elevator hall, the transport reader automatically senses the patient's wristband at a distance of 30 centimeters. The reader quickly reads the read-only identity information (Zhang, 2023102505) in sectors 4-8 of the wristband and the "initialized" status flag in sector 3, and generates a wristband data copy in the device's memory.

[0056] Verification factor generation and formula validation reader obtains the current system time. =08:40) and location beacon =ELEV-SURG-03. The system combines the wristband data copy to generate a verification factor and matches it with the pre-loaded "Transfer Task Order (Task Number: TR-20231025-099)". During this process, the system uses a matching logic formula to calculate the transfer validity judgment value. To ensure that patients are transferred within the correct time window: ; in, This is an indicator function; it is 1 when the wristband ID matches the task ID, and 0 otherwise. This is a step function used to determine whether the time deviation is within the allowable range; The scheduled surgery time is 09:00. The system's preset maximum allowable lead time for transit is set to 45 minutes. Calculation results: ID matching successful (1), time difference is 20 minutes, less than the 45-minute threshold (1). Therefore... =1x1=1 (Validation passed).

[0057] Matching result processing and status update, due to =1, the system generates a "successful match" result. The reader immediately performs the following operations: build a record: package the verification factor (including time 08:40, location ELEV-SURG-03) with the "successful match" result to generate a 64-byte transit verification record.

[0058] Write to wristband: The reader appends the record to the "verification log storage area" of sector 9 of the wristband via the 13.56MHz frequency band. State flip: The reader simultaneously writes a new hexadecimal status code to sector 3, overwriting the original "initialized" flag, and officially updates the wristband status to "transfer confirmation status".

[0059] Anomaly simulation (backup strategy): Assuming that in the above steps, network latency causes the task order to fail to synchronize in a timely manner, resulting in a "failure alarm (task order mismatch)". The reader screen immediately turns red and vibrates. Transport operator Wang then activates the supplementary verification strategy: he clicks "Scan Code Verification" on the screen and uses the reader's camera to scan the QR code on the wristband surface. The device parses the offline encrypted verification code contained in the QR code and compares it locally with the wristband chip data. After successful comparison, the system generates a supplementary verification record with a "Manual Intervention" identifier, writes it to the wristband log area, and forcibly updates the status to "Transport Confirmation Status" to ensure that the surgical procedure is not interrupted by a simple network failure.

[0060] 203. The operating room reader reads the data of the wristband in the transfer confirmation state in a non-contact manner at the entrance of the operating room, compares it with the surgical scheduling data, and generates a surgical checklist. Specifically, the operating room reader reads all data from the wristband in the transfer confirmation state and extracts the transfer verification record from the wristband's verification log storage area to generate a complete wristband data summary; it obtains the patient's identity, surgery name, and surgical site information currently scheduled in the operating room from the surgical scheduling system to generate real-time surgical scheduling data; it performs a multi-dimensional comparison between the patient's identity and surgical information in the wristband data summary and the real-time surgical scheduling data, including at least identity matching comparison and surgical information consistency comparison, and generates a difference comparison report; based on the time information in the transfer verification record, it compares it with a preset valid time threshold to verify the timeliness of the wristband data and generates a data timeliness status; it verifies the continuity of the signature or verification chain of the data storage block from the time the wristband data is written to the time it is read, and generates a data integrity status; and it combines the difference comparison report, data timeliness status, and data integrity status to generate a surgical verification list including patient identity, surgical details, verification items, and various verification results.

[0061] It should be noted that the implementation time was 08:50 AM, which is 10 minutes after patient Zhang completed the transfer verification at the elevator entrance. The surgical trolley arrived at the entrance of operating room 3 (OR-03). The fixed operating room reader (device ID: OR-GATE-03) installed on the side of the door frame was automatically activated, and a strict "access qualification review" was carried out on the patient about to enter the room.

[0062] When the stretcher passes through the reader's sensing area, the device reads the wristband non-contactly. It identifies the "Transfer Confirmation Status" marker in sector 3, confirming that the patient has legally completed the transfer process. Subsequently, the reader retrieves the transfer verification record generated at 08:40 from the "Verification Log Storage Area" and reads the patient's identity and medical warning information from the "Read-Only Information Layer," generating a complete wristband data summary in local memory.

[0063] The reader immediately sends a request to the operating room's backend system to query the scheduling information for the current time period (09:00) of "OR-03," obtaining real-time surgical scheduling data. The device's internal processor performs a multi-dimensional comparison between the wristband data summary and the scheduling data, generating a difference comparison report. The specific comparison logic and results are shown in Table 2 below: Table 2

[0064] After comparing the information content, the reader performs a security logic check: Timeliness verification: The timestamp of the transport record is read as 08:40, and the current time is 08:50. The time difference between the two is 10 minutes. The system compares this with the preset "valid time threshold after transport" (set to 60 minutes). 10 minutes is much less than 60 minutes, so the data is determined to be in a "fresh" and valid state, generating a "valid timeliness" status code.

[0065] The device scans the hash verification chain of the wristband storage block to confirm that the data has not been bit-flipped or illegally tampered with since it was written to the ward, and generates an "integrity passed" status code.

[0066] Based on the above comparison report (full match), timeliness status (valid), and completeness status (passed), the operating room reader generates the final "Surgical Checklist" on the screen. This checklist is highlighted in green as "Access Passed" and automatically lists key items to be confirmed (identity, surgical procedure, site, allergy history). Simultaneously, the wristband is locked, awaiting further "three-way verification" by medical staff using a handheld device. If any comparison item does not match, the system will immediately issue an audible and visual alarm and refuse to generate the checklist.

[0067] 204. Before the surgical incision, medical staff use a handheld reading and writing device to read the wristband in a non-contact manner and obtain the surgical checklist for joint verification. The handheld reading and writing device writes the verification result into the wristband, putting the wristband into the surgical ready state and authorizing the start of the surgery.

[0068] Specifically, the surgeon, anesthesiologist, and circulating nurse each use their own handheld reading devices to sequentially read the wristband in a non-contact manner to obtain the surgical checklist. Each medical staff member independently verifies the patient's identity, surgical name, surgical site, and medical warning information on the surgical checklist on their respective handheld reading device, generating an independent confirmation signal including the confirmation time and operator identification. Any handheld reading device acts as a verification coordination node, receiving independent confirmation signals from other handheld reading devices and aggregating all received independent confirmation signals with its own generated independent confirmation signal to generate a joint verification result. When the joint verification result shows that all required confirmation items have been independently verified by all three parties, the verification coordination node generates a verification pass instruction. The verification coordination node writes the verification pass instruction and the complete joint verification result as a surgical authorization mark into the designated status storage area of ​​the wristband in a non-contact manner, overwriting the previous status mark and putting the wristband into a surgical ready state. The surgical ready state serves as the sole electronic credential for subsequent surgical equipment or recording systems to verify permissions before performing critical operations.

[0069] It should be noted that the scenario took place at 09:15 AM. At this time, patient Zhang had completed anesthesia induction and was draped in sterile sheets, and was in the "Time-Out" stage before the surgical incision. The chief surgeon, Dr. Li, the anesthesiologist, Dr. Wang, and the circulating nurse, Nurse Chen, each held a handheld H-Verify-Pro reader / writer device and gathered around the operating table to conduct a final three-way independent electronic verification.

[0070] Three medical staff simultaneously activated their handheld devices and brought them close to the patient's wristband (about 10 centimeters away). The devices read the "transfer confirmation status" in sector 3 of the wristband and the verification log in sector 9, and the "surgical checklist" generated in the previous step immediately popped up on the screen.

[0071] The three surgeons, each fulfilling their respective responsibilities, blindly checked the list on their respective devices: Chief Surgeon Li confirmed the patient was "Zhang," the surgical procedure was "laparoscopic cholecystectomy," and the surgical site markings were correct. Dr. Wang (Anesthesiologist) confirmed the "penicillin allergy" red warning had been addressed and the airway assessment was complete. Nurse Chen (Circulating Nurse) confirmed the integrity of the sterile instrument pack and the preparation of implants. After confirming everything was correct, the three almost simultaneously pressed the "Confirm Passed" virtual button on their respective devices. At this point, each device generated an independent confirmation signal with a timestamp and digital signature.

[0072] The system pre-sets the circulating nurse's handheld device (ID: DEV-NURSE-003) as the verification and coordination node for this operation. This device automatically receives confirmation signals from the surgeon's and anesthesiologist's devices via Bluetooth Low Energy and performs a convergence logic check against its own confirmation signal. The device screen displays the real-time convergence results in Table 3 below: Table 3

[0073] The verification and coordination node detects that all three parties' signals in the table are in the "signed" state, and the time difference is within the allowed synchronization window (30 seconds). The system determines that the "joint verification result" is passed. The coordination node then generates an encrypted verification pass command and transmits a high-frequency signal to connect to the wristband again: Write Authorization: Write the summary information confirmed by the above three parties to the wristband verification log area.

[0074] Status Update: A specific hexadecimal authorization code is written to the wristband status control area, overwriting the original "transfer confirmation" mark and officially activating the wristband to "surgery ready status".

[0075] With a long beep, the wristband screen turned green. At this moment, the operating room's intelligent surgical scalpel control console scanned the wristband, recognized the "surgery ready" authorization code, automatically unlocked the power, and permitted Director Li to perform the skin incision. The surgery officially began.

[0076] 205. When any reader fails to read the wristband non-contactly, an emergency verification process is triggered: Medical staff use the optical scanning unit of the handheld reader to scan the visually encoded pattern printed on the wristband surface and decode it to obtain the core verification data; the handheld reader compares the core verification data with the scheduling data in the current operating room system to generate an emergency verification result; if the emergency verification result passes, the handheld reader generates an emergency verification voucher with a time limit; the emergency verification voucher is displayed optically on the screen of the handheld reader for the surgical team to perform manual visual verification and confirmation; the emergency verification result and the generation record of the emergency verification voucher are uploaded to the operating room back-end system to form an emergency verification log; the emergency verification log is used for combined auditing with the regular verification records after the operation.

[0077] Specifically, after the emergency verification process is completed, the status recovery and record synchronization process is executed. The status recovery and record synchronization process includes: monitoring the status of the non-contact communication link between the handheld reader / writer and the wristband; when the communication link is detected to be available again, a communication recovery signal is generated; in response to the communication recovery signal, the handheld reader / writer encapsulates the key confirmation information in the emergency verification log into a status update instruction; the status update instruction is written to the wristband in a non-contact manner to overwrite the previous status marker on the wristband, updating it to the surgical readiness state corresponding to the emergency verification result, thereby completing the physical restoration of the wristband; the handheld reader / writer associates the writing result of the status update instruction with the locally stored emergency verification log to generate a complete verification record including the emergency process and the recovery process; the complete verification record is uploaded to the operating room backend system to replace or supplement the previously uploaded emergency verification log, forming a continuous surgical verification file that can be audited and has no status breakpoints.

[0078] It should be noted that the scenario took place at 09:16 AM. At this critical moment, just before the surgery was about to begin, circulating nurse Chen attempted to use a handheld reader (ID: DEV-NURSE-003) to read patient Zhang's wristband to confirm the surgery was ready. However, due to electromagnetic interference from the high-frequency electrosurgical unit next to the operating table, the reader displayed a "communication link interruption (RF_ERR_TIMEOUT)" message three times consecutively, failing to read the electronic data from the chip.

[0079] Faced with the RF reading failure, Nurse Chen immediately clicked the "Emergency Verification" button on the device screen. The device automatically shut down the RF module and activated the optical scanning unit. Nurse Chen scanned the high-density QR code printed on the wristband. The device completed decoding within 0.5 seconds, extracting the core verification data: patient ID "2023102505", name "Zhang Mou", and the encrypted original hash value "HASH-A7F2".

[0080] The handheld device decodes the patient's name and ID and performs a forced comparison with the locally cached "OR-03 Operating Room 09:00 Schedule". The system confirms that the scanned patient information is completely consistent with the schedule and generates an emergency verification result of "Pass". The device screen then displays the emergency verification certificate with a prominent orange background, including: "Emergency Passed: Zhang / Cholecystectomy / Valid for 15 minutes". The surgeon and anesthesiologist visually confirm the information is correct by looking at the certificate displayed on the screen and verbally announce, "Verification complete, we can begin." At this point, the device automatically uploads the emergency verification log, containing the fault code, scan time (09:17:05), and verification result, to the backend as the first phase of audit documentation.

[0081] At 9:20 AM, the electrosurgical unit was debugged and paused, and the electromagnetic environment returned to normal. The background process of the handheld device detected that the near-field communication link with the wristband had been restored and automatically generated a communication restoration signal. Based on the previous optical verification results, the device encapsulated a status update command in the background. Nurse Chen brought the device close to the wristband again, and the device silently wrote the authorization mark representing the "surgery ready status" into the wristband chip, overwriting the previous "transfer confirmation" status. This step ensured that the physical and electronic state of the wristband was resynchronized with the actual surgical progress, repairing the status gap caused by interference.

[0082] After confirming successful writing, the handheld device links the "record of successful optical verification" with the "record of successful physical status restoration," generating a complete verification record without any breaks. This record is uploaded to the operating room's backend system, automatically replacing the previous, sparse emergency log. The final audit file shows that the patient passed the emergency verification at 09:17 and completed the closed-loop restoration of the electronic status at 09:20, ensuring the rigor and consistency of the medical records.

[0083] The above describes the smart wristband data synchronization method for preoperative safety verification in embodiments of the present invention. The following describes the smart wristband data synchronization system for preoperative safety verification in embodiments of the present invention. Please refer to [link / reference]. Figure 6The embodiment of the intelligent wristband data synchronization system for preoperative safety verification in this invention includes: an information module 301, used by the ward reader to generate a first synchronization instruction including patient identity information, medical information, and planned surgery information, and write the first synchronization instruction into the storage chip of the wristband, so that the wristband enters an initialized state; a transport module 302, used by the transport reader to read the wristband data in the initialized state during patient transport, generate a transport verification record, and write the transport verification record into the wristband, so that the wristband enters a transport confirmation state; a verification module 303, used by the operating room reader to read the wristband data in the transport confirmation state at the entrance of the operating room, compare it with the surgical scheduling data, and generate a surgical verification list; and an authorization module 304, used to read the wristband before surgical incision, obtain the surgical verification list for joint verification, and the handheld reader writes the verification confirmation result into the wristband, so that the wristband enters a surgical ready state to authorize the start of surgery.

[0084] In another embodiment of the smart wristband data synchronization system for preoperative safety verification, an emergency module is also included to trigger an emergency verification process when any reading / writing device fails to read the wristband in a non-contact manner.

[0086] In the example, transmitter 401 modulates (e.g., analog-to-analog conversion, filtering, amplification, and up-conversion, etc.) the output sample and generates an uplink signal, which is transmitted via an antenna to the access network equipment. On the downlink, the antenna receives the downlink signal transmitted by the access network equipment. Receiver 402 modulates (e.g., filtering, amplification, down-conversion, and digitization, etc.) the signal received from the antenna and provides an input sample. In modem processor 405, encoder 406 receives service data and signaling messages to be transmitted on the uplink and processes (e.g., formatting, encoding, and interleaving) the service data and signaling messages.

Demodulator 409 processes (e.g., demodulates) the input sample and provides a symbol estimate. Decoder 408 processes (e.g., deinterleaving and decoding) the symbol estimate and provides decoded data and signaling messages to device 400. Encoder 406, modulator 407, demodulator 409, and decoder 408 can be implemented by a combined modem processor 405. These units perform processing according to the radio access technology adopted by the radio access network (e.g., LTE and other evolved systems access technologies). It should be noted that when device 400 does not include modem processor 405, the above-mentioned functions of modem processor 405 can also be performed by processor 403.

The complete verification record is uploaded to the operating room backend system to replace or supplement the previously uploaded emergency verification log, forming a continuous surgical verification file.

10. A smart wristband data synchronization system for preoperative safety verification, characterized in that, The smart wristband data synchronization system for preoperative safety checks includes: The information module is used by the ward reader to generate a first synchronization instruction including patient identity information, medical information and planned surgery information, and write the first synchronization instruction into the storage chip of the wristband, so that the wristband enters the initialized state; The transport module is used by the transport reader to read the wristband data in the initialized state during the patient transport process, generate a transport verification record, and write the transport verification record into the wristband, so that the wristband enters the transport confirmation state. The verification module is used by the operating room reader to read the wristband data in the transfer confirmation state at the entrance of the operating room, compare it with the surgical scheduling data, and generate a surgical verification list. The authorization module is used to read the wristband before surgical incision, obtain the surgical checklist for joint verification, and the handheld reading and writing device writes the confirmation result of the verification into the wristband, so that the wristband enters the surgical ready state and authorizes the start of the surgery.

11. The intelligent wristband data synchronization system for preoperative safety verification according to claim 10, characterized in that, It also includes an emergency module, which triggers an emergency verification process when any reader fails to read the wristband in a contactless manner.
