A case manager work terminal

Abstract

The application discloses a case manager work terminal. The terminal physically connects an audio and video evidence leaving module with a sealing glue and a secure clock chip. The chip generates a signed timestamp with a signature time stamp at the moment of evidence collection, which is bound with the physical data and card information as an evidence data package. The impedance of the power supply loop of the evidence leaving module, the opening of the anti-disassembly strip warehouse, the insertion and extraction of the physical module, and the in-place signal of the trolley locking part are detected to bind abnormal events and follow-up work order records. The evidence data package is subjected to a hash operation to obtain an evidence summary. The evidence is uploaded and charged through the trolley locking part electric contact when locking, and is locally cached for uploading when offline. The evidence data package is divided into evidence storage segments according to the follow-up process nodes. Each segment contains a previous segment hash and is signed by a chip internal non-directable hardware key. The signature value participates in the next segment hash calculation to form a segmented chain structure. The application is used for the credible storage and auditing of follow-up evidence chain, and does not involve medical judgment conclusion and medical treatment method.

Description

Technical Field

[0001] This invention relates to the field of medical follow-up service equipment and data processing technology, specifically to a portable case manager's workstation integrating structured scale entry, card reading, vital sign collection, audio and video evidence retention, and tamper-proof structure, as well as a method, system, and storage medium for processing follow-up service evidence data. This invention only collects, timestamps, and marks the physical signals and recorded data generated during the follow-up process; it does not output any medical judgment conclusions or involve any medical treatment methods. Background Technology

[0002] When case managers (follow-up nurses or members of the family doctor team) provide home visits, they need to simultaneously complete structured assessment questionnaire entry, identity and medical insurance card verification, vital sign collection, and audio / video evidence recording. Existing publicly available solutions have the following shortcomings: First, vital sign collection, card reading, and audio / video evidence recording are disclosed independently. For example, CN102117384A discloses a portable remote multi-parameter vital sign monitoring terminal that includes ECG, temperature, blood pressure, and blood glucose collection and audio / video, and GPS remote transmission; CN205649492U discloses a portable multi-vital sign data detection all-in-one machine; CN108618847A discloses a mobile health follow-up device including a cabinet, display device, and a pull-out medicine compartment; and CN218162653U... The mobile follow-up devices that can record video publicly include a recording module, main control unit, and memory card; secondly, the evidence videos are stored on ordinary memory cards, which can be re-recorded or replaced afterward, making the evidence chain unreliable; thirdly, there are no records of the use of seals and consumables, making it impossible to prevent unauthorized disassembly and replacement; fourthly, damage to the vital signs module requires the entire device to be returned to the factory, resulting in high maintenance costs for grassroots staff; fifthly, there is no unified charging, data synchronization, and locking structure between the portable terminal and the hospital cart, and the evidence data needs to be exported separately in offline mode when switching between the two modes, increasing the human intervention link; sixthly, service process data is centrally stored on the server side, and the data of each node of assessment, planning, execution, and follow-up under the same follow-up work order are stored independently, with no hash coupling relationship between nodes, and historical nodes can be rewritten individually without being detected.

[0003] The aforementioned prior publications disclosed individual features in vital sign collection, audio / video evidence retention, and card / identity card recognition, but no single document has disclosed a complete structure that integrates all four into a single shell and further achieves a reliable follow-up evidence chain and dual-form universality through tamper-proof sealing, physical binding of the evidence retention module and security clock chip, hot-swappable vital sign module, and trolley locking combination structure. Furthermore, no single document has disclosed a method for rolling the non-derivative hardware key signature value from the terminal's security chip into the hash of the next evidence storage segment, creating an unalterable coupled segmented chain evidence storage structure between each node segment. This invention aims to provide an integrated work terminal and evidence data processing solution for follow-up service processes that offers a reliable evidence chain, on-site module maintenance, and dual-form universality both inside and outside the hospital. Summary of the Invention

[0004] The technical problem to be solved by this invention is: in the scenario of case managers visiting patients at home, to ensure that the audio and video evidence of the follow-up visit, as well as the vital signs and card data, are irreplaceable afterward, and that the chain of evidence is credible; to enable the vital signs module to be hot-swapped and maintained on-site; and to enable the portable terminal and the hospital cart to achieve unified charging, data synchronization and locking dual-mode switching, while forming an unalterable chain coupling between the process data of each process node under the same follow-up work order.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for processing evidence data in follow-up services is applied to a case manager's work terminal in a case manager's home follow-up scenario. The terminal includes an audio / video evidence module and a security clock chip physically secured with adhesive, a vital signs module insertion area for hot-plugging a vital signs acquisition module, an tamper-proof sealing compartment, and a trolley locking mechanism for locking with a follow-up trolley. The method includes: acquiring identity information and medical insurance card information collected by a dual-card reader module, and vital signs data measured by a vital signs acquisition module hot-plugged into the vital signs module insertion area. The vital signs data includes at least one of blood pressure and blood glucose data, or includes blood oxygen saturation data obtained by filtering and ratio calculation of transmitted or reflected light intensity signals collected by a photoelectric sensor; at the moment the audio / video evidence module acquires the follow-up audio / video data, the method further includes: The secure clock chip generates a timestamp with a digital signature and binds the timestamp, vital sign data, identity information, and medical insurance card information into an evidence data package. It detects the power supply circuit impedance of the audio / video evidence module, the opening event of the tamper-evident seal compartment, the insertion / removal event of the vital sign module's connector area, and the presence signal of the trolley's locking mechanism. It binds and records the type of any abnormal event, its corresponding timestamp, and the current follow-up work order number. It performs a hash operation on the evidence data package to obtain an evidence digest. When the presence signal is valid, the evidence digest is uploaded to the server for storage via the electrical contacts of the trolley's locking mechanism, and the follow-up trolley charges the terminal. When the presence signal is invalid, the evidence digest is cached locally on the terminal for later upload. When any link in the evidence chain is missing, the current follow-up record is marked as pending review.

[0006] The follow-up service evidence data processing method further includes: the evidence data package is divided into several evidence storage segments according to the follow-up process nodes, each evidence storage segment includes a node type, service data digest, hash value of the previous evidence storage segment and timestamp generated by the secure clock chip, forming a segmented chain structure; each evidence storage segment is signed by the hardware key of the writing operator, the hardware key is stored in the secure clock chip and cannot be exported, the signature is bound to the device identifier and the operator identifier, and the signature value of the signature participates in the hash calculation of the next evidence storage segment; hierarchical reading permissions are configured for the segmented chain structure according to the writer role; timestamp rewriting in reverse order, hash chain rewriting, and unauthorized writing where the hardware key does not match the writer role are detected, and when any of the above situations are detected, the abnormal segment is marked and locked for manual auditing.

[0007] A follow-up service evidence data processing system includes a dual-card reading module, a vital sign collection module, an audio and video evidence retention module, a security clock chip, an tamper-proof seal compartment, a trolley locking mechanism, and a processing unit. The audio and video evidence retention module is physically fixed to the security clock chip on the same circuit board via adhesive. The trolley locking mechanism includes a dovetail groove, electrical contacts, and an electromagnetic lock. The processing unit is configured to perform the steps of the aforementioned method.

[0008] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the aforementioned follow-up service evidence data processing method.

[0009] A case manager's work terminal includes a housing, a touch-sensitive questionnaire input module, a dual-card reader module, an audio / video evidence retention module, a secure clock chip, a vital signs module insertion area, an tamper-proof seal compartment, and a trolley locking mechanism. The audio / video evidence retention module is fixed to the secure clock chip on the same flexible circuit board with adhesive. Removing the audio / video evidence retention module disrupts the power supply circuit of the secure clock chip. The vital signs module insertion area consists of a guide groove, spring contacts, and a latch, forming a unified mechanical and electrical interface to allow for hot-swapping of the vital signs module. The tamper-proof seal compartment includes a roll-up seal, a cutting edge, and a micro switch for the compartment door. The trolley locking mechanism includes a dovetail groove, electrical contacts, and an electromagnetic lock to engage with the follow-up trolley for charging and data synchronization. The secure clock chip stores a non-exportable hardware key, which is used to generate the digital signature and sign each evidence retention segment. Beneficial effects

[0010] The beneficial effects of this invention are manifested through quantifiable technical indicators: First, the timestamp of the retained audio and video is generated by the hardware security clock chip at the moment of acquisition and carries a digital signature. It is bound to the vital signs data, card information, and operator information in a unified whole. Subsequent replacement of any link requires simultaneously breaking the physical connection of the adhesive and the chip signature. The detection rate of evidence tampering is 100% after the hash is uploaded to the blockchain. Second, the audio and video evidence retention module and the security clock chip are physically fixed together by adhesive. Removal will destroy the power supply circuit of the clock chip. When the terminal is powered on, the impedance of the power supply circuit is checked. If the impedance is abnormal, the evidence retention function is locked. The anti-tamper linkage makes the cost of unauthorized removal of the evidence retention module significantly higher. The improvements include: Third, the vital signs module is hot-swappable via a unified mechanical and electrical interface, reducing the time for on-site replacement from approximately seven days (returning the entire unit to the factory) to less than thirty seconds. Fourth, the trolley locking mechanism allows for seamless switching between in-hospital charging and archiving and out-of-hospital portable use; locking immediately uploads and charges, while offline operation results in local caching, eliminating the need for manual export. Fifth, the tamper-proof seal compartment leaves a trace upon opening, and consumables are protected against unauthorized tampering. Sixth, the signature value of each process node's evidence storage segment rolls into the next hash segment; rewriting any historical node causes subsequent hash segments to break the chain. Combined with timestamp reversal and unauthorized write detection, historical nodes cannot be individually modified. These improvements are the result of technical enhancements brought about by the physical binding of the tamper-proof seal compartment, the evidence storage module, and the secure clock chip; the hot-swappable module interface; the trolley locking combination structure; and the segmented chain-like signature coupling relationship.

Specific implementation

[0020] Example 1 (Terminal Product Structure): As shown Figure 1 As shown, the housing (1) is made of ABS and PC alloy injection molding, with dimensions of 240 mm x 160 mm x 45 mm. The touch screen constitutes the touch measurement input module (2), with a size of 8 inches. The ID card reading area (11) and the medical insurance card reading area (12) of the dual card reading module (3) are arranged side by side 20 mm below the touch screen, with a spacing of 30 mm. The audio and video evidence module (4) is located on the top of the housing (1) and includes a camera (13) and a microphone (14). The audio and video evidence module (4) is fixed to the security clock chip (5) on the same flexible circuit board (15) by a sealing glue (10) (epoxy electronic glue), and the fixed area covers the power supply solder joint (16) of the security clock chip (5). Forcibly removing the audio and video evidence module (4) will tear the power supply circuit (17), and the security clock chip (5) will lose power. When the terminal is powered on again, it will check the impedance of the power supply circuit (17) of the security clock chip (5). If the impedance is abnormal, the evidence retention function will be locked and an alarm will be reported. Figure 2 As shown, the vital signs module insertion area (6) is located on the side of the housing (1), with two standard insertion positions. Each insertion position contains four spring contacts (19) (two power pins and two data pins) and an elastic latch (20). Guide grooves (18) are located on both sides of the insertion position to guide the insertion of the vital signs acquisition module (22). A micro switch (21) is connected in series with the linkage rod of the latch (20) to record insertion and removal events. Figure 4As shown, the tamper-evident seal compartment (7) is located at the rear of the housing (1), and includes a roll-up seal (23), a cutting edge (24), and a door micro switch (25). A door micro switch (25) is located at the pivot of the door (26). The opening event signal is connected to the terminal main control. The cutting edge (24) is used to cut off the pulled-out roll-up seal (23). Figure 5 As shown, the trolley locking part (8) is located at the bottom of the housing (1). The dovetail groove (27) is 40 mm wide and contains six electrical contacts (28) (two charging contacts, two data contacts, and two in-situ detection contacts) and an electromagnetic lock (29). When locked with the follow-up trolley (30), the follow-up trolley (30) charges the terminal and synchronizes the data through the electrical contacts (28). The electromagnetic lock (29) is controlled by the terminal master control.

[0021] Example 2 (Evidence Data Processing Method): As follows Figure 7 As shown, at the start of the follow-up, the dual-card reading module (3) reads the identity information and medical insurance card information and starts the audio and video evidence module (4); at the moment when the audio and video evidence module (4) collects the follow-up audio and video data, the security clock chip (5) generates a timestamp with a digital signature and binds the timestamp, vital sign data, identity information and medical insurance card information into an evidence data package (32). The vital sign data is measured by the vital sign acquisition module (22) that is hot-swappable to the vital sign module plug-in area (6), including at least one of blood pressure data and blood glucose data, or includes blood oxygen saturation data obtained by filtering and ratio calculation of the transmitted light intensity signal or reflected light intensity signal collected by the photoelectric sensor; the filtering and ratio calculation is completed by the filter ratio calculation circuit built into the blood oxygen module, first filtering out the DC component and ambient light interference, and then performing a ratio calculation on the AC component and DC component of the two light intensity signals. The terminal detects the abnormal impedance of the power supply circuit (17) of the audio and video evidence module (4), the opening of the anti-tamper seal compartment (7), the unauthorized insertion and removal of the vital signs module plug-in area (6), and the presence signal of the trolley locking part (8). It binds the event type, timestamp and the current follow-up work order number and records them and reports them immediately. The evidence data packet (32) is hashed to obtain the evidence digest. When the presence signal is valid, the terminal is locked with the follow-up trolley (30) through the trolley locking part (8), and the evidence digest is uploaded to the evidence storage server (31) through the electrical contact (28) and charged by the follow-up trolley (30). When the presence signal is invalid, the evidence digest is cached locally on the terminal and is to be uploaded. If any link in the evidence chain is missing, the follow-up record is marked as pending review. The difference between CN218162653U and simple video recording storage is that the evidence data is physically bound to the hardware timestamp and the anti-tamper event and cannot be replaced afterward.

[0022] Example 3 (System Deployment): As Figure 6As shown, the follow-up service evidence data processing system is deployed on the case manager's work terminal in Example 1. The processing unit (9) is connected to the contact measurement scale entry module (2), the dual card reading module (3), the vital signs collection module (22), the audio and video evidence retention module (4), the security clock chip (5), the tamper-proof seal compartment (7), and the trolley locking part (8), and executes the method steps of Example 2. The security clock chip (5) is a real-time clock security chip with temperature compensation. Its digital signature is generated by a non-derivative hardware key (35) in the chip. The digital signature is bound to the device identifier and the operator identifier. When the trolley locking part (8) is locked, it is locked by the electromagnetic lock (29) and sends an in-situ signal to the processing unit (9), triggering charging and data synchronization.

[0023] Example 4 (Segmented Chained Signature and Evidence Storage): For example... Figure 8 As shown, the evidence data packet (32) is divided into several evidence storage segments (33) according to the follow-up process nodes. The follow-up process nodes include four categories: assessment, planning, execution, and follow-up. The fields of each evidence storage segment (33) are node type, service data digest, front-end hash (34), and timestamp generated by the secure clock chip (5). The front-end hash (34) is taken from the overall hash value of the previous evidence storage segment (33). The segments are thus connected end to end to form a segmented chain structure. Each evidence storage segment (33) is signed by the hardware key (35) of the operator. The hardware key (35) is generated and stored in the secure clock chip (5) and cannot be exported. The signature is bound to the device identifier and the operator identifier, and the signature value of the signature participates in the hash calculation of the next evidence storage segment (33). That is, the front-end hash (34) of the next segment is obtained by hashing all the fields of this segment together with the signature value of this segment. Therefore, rewriting any historical evidence storage segment (33) will break the chain of the front-end hashes (34) of all subsequent segments. The system configures hierarchical reading permissions according to the writer's role, forming a three-level structure: family members read the summary, operators read the node certificate, and supervisors read the entire chain. It also detects timestamp rewriting, hash chain break rewriting, and unauthorized writing where the hardware key (35) does not match the writer's role. If any of the above situations are detected, the abnormal segment is marked and locked for manual audit. For example, if an operator attempts to rewrite a service record from three days ago, the difference between the timestamp of the new segment and the current value of the security clock chip (5) exceeds the threshold, and the insertion of this segment into the historical position causes the hash (34) of the preceding segments of subsequent segments to break, the system will mark the rewriting and chain break as abnormal. Data compliance and ethical design

[0024] The data processing in this implementation follows the following compliance and ethical requirements: the legal basis is the explicit authorization of the careee and the case manager under the follow-up service agreement and the principle of minimum necessity; the scope of collection includes identity information, medical insurance card information, vital sign data (blood pressure, blood oxygen, blood glucose) and follow-up audio and video evidence data, without collecting voice content recognition results, and without outputting any medical judgment conclusions or medical treatment plans; health data is de-identified locally and then transmitted encrypted, and the original evidence audio and video does not leave the terminal or upload to unauthorized nodes; the secure clock chip signature key is generated and stored on the terminal side and cannot be exported, and the hash value of the evidence data packet is stored on the blockchain; under the hierarchical reading permissions, family members can only read the summary, the handler can read the node certificate, and the supervisor can read the entire chain, and any reading request is verified by permissions and does not contain unauthorized amplification; this invention does not change any medical or nursing judgment conclusions, and the output is only the quantitative record data and evidence records of the follow-up process; the preset assessment scale and rule base do not contain any discriminatory labels based on region, gender, or age, and the rule settings meet the requirements of fairness and non-discrimination. The aforementioned minimum necessary requirements, hierarchical reading, and data leaving the domain design are implemented in accordance with Article 5 of the 2026 revised review guidelines.
