Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable medical wristband and system that combines anti-tampering and easy-to-disassemble functions. Background Technology

[0002] In patient safety management at medical institutions, identification wristbands are an important verification tool. Currently, most wristbands are made of disposable materials and secured with buckles or locks, which presents significant shortcomings in management and use.

[0003] Regarding tamper prevention, the system primarily relies on the physical strength of the wristband, and its condition depends entirely on manual inspection, lacking automated monitoring and early warning systems, thus creating security blind spots. In terms of process management, wristband removal is typically just a simple physical cutting action, disconnected from patient discharge orders, settlement procedures, and other medical compliance processes, and without any system record. Furthermore, while the wristband's length is adjustable, the adjustment is arbitrary and lacks electronic recording, making it impossible to link to clinical causes or establish nursing traceability. Additionally, although some wristbands integrate QR codes or RFID tags, these are only used for identification; the wristband's physical status is completely isolated from the hospital's information system, making it not a manageable smart terminal.

[0004] Therefore, there is an urgent need for an intelligent management solution that can deeply integrate the physical state of the wristband with the information system to achieve status monitoring, authorized operation, and full traceability. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable medical wristband and system that combines anti-tampering and easy-to-disassemble functions, so as to overcome the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An adjustable medical wristband system that combines tamper-proof and easy-to-remove functions includes: The wristband terminal is equipped with independent machine-readable identification units and permanent identification units; the machine-readable identification units are circuit state-dependent identification chips. A disposable buckle is used to secure the wristband terminal in an adjustable tightness in a wearing state; wherein the physical integrity of the disposable buckle determines the on / off state of the chip's activation circuit. The mobile authorization terminal is used to read the machine-readable identifier unit and, upon successful reading, initiate an operation request related to the one-time lock; if reading fails, it reads the permanent identifier to obtain the identifier information of the wristband terminal and generates abnormal event information. A backend management server is used to receive and process the operation requests or abnormal event information. The backend management server includes: The authorization verification module is used to perform authorization verification on the operation request. The authorization verification includes verifying the operator's permissions and rule compliance, and only generates a permission instruction after the authorization verification is passed, authorizing the execution of the corresponding physical operation on the one-time lock. The anti-tamper monitoring module is used to monitor the reading status of the machine-readable identification unit and execute an early warning process when abnormal event information is detected.

[0007] Furthermore, the physical integrity of the one-time latch determines the on / off state of the activation circuit, which is achieved through the following structure: The wristband terminal has a first wire and a second wire pre-embedded inside, which are connected to the two ends of the chip, and the two ends of the wristband terminal are respectively provided with a plurality of corresponding adjustment holes; the ends of the first wire and the second wire are respectively connected to the first conductive part and the second conductive part at the adjustment holes at both ends of the wristband terminal. The disposable buckle has a first conductive layer and a second conductive layer on its circumferential surface that contacts the adjustment hole. The first conductive layer and the second conductive layer are respectively positioned corresponding to the first conductive part and the second conductive part. The first conductive layer and the second conductive layer are electrically connected through a connecting wire disposed inside the buckle. When the buckle is fully inserted and locked, its first conductive layer, internal connecting wires and second conductive layer form a conductive bridge, which electrically connects the first conductive part and the second conductive part of the wristband terminal, so that the first wire, chip, second wire and the conductive bridge of the buckle together form a conductive activation circuit. When the latch is physically damaged, causing the internal connecting wires to disconnect, the conductive bridge function fails and the activation circuit is disconnected.

[0008] Furthermore, the authorization verification includes verifying the operator's permissions and rule compliance, specifically: Disassembly authorization verification: In response to the disassembly request, verify the preset set of discharge compliance conditions; Adjust authorization verification, responding to adjustment requests, and verifying operation permissions and adjustment reasons.

[0009] Furthermore, the set of discharge compliance conditions for the disassembly authorization verification includes: the electronic discharge order has taken effect, medical expenses have been settled, and there are no pending medical order tasks. The adjustment reason is selected from a predefined reason list, which includes: patient edema, skin pressure discomfort, and preventative adjustment.

[0010] Furthermore, the authorization verification module is also configured as follows: After the adjustment authorization verification is passed, an adjustment event is recorded as in progress; and after receiving confirmation of adjustment completion from the mobile authorization terminal, the adjustment event status is updated to completed, and the latch replacement is recorded as complete. After the disassembly authorization verification is passed and the license instruction is generated, a disassembly event is recorded as authorized; and after receiving confirmation of disassembly completion from the mobile authorization terminal, the disassembly event status is updated to completed.

[0011] Furthermore, the abnormal event information includes at least the identification information of the wristband terminal and the event type of the reading failure.

[0012] Furthermore, the execution of the early warning process specifically involves: receiving the abnormal event information, and based on the identification information of the abnormal event information, querying the system to see if there is a valid authorization record for disassembly or adjustment of the wristband terminal; if no authorization record exists, generating and issuing an unauthorized disassembly early warning message.

[0013] Furthermore, the permanent identifier is a visually readable identifier, which has unique identification information associated with the machine-readable identifier unit.

[0014] Another object of the present invention is to provide an adjustable medical wristband for use in the aforementioned adjustable medical wristband system that combines anti-tampering and easy-to-remove functions, comprising: The wristband terminal is adjustable in length and is equipped with a circuit state-dependent identification chip and a permanent identifier; A disposable buckle is used to secure the wristband terminal in an adjustable tightness while it is worn. The physical integrity of the one-time latch determines the on / off state of the chip's activation circuit.

[0015] Another object of the present invention is to provide a medical wristband management method for an adjustable medical wristband system that combines anti-tampering and easy-to-remove functions, comprising the following steps: Wearing and binding: Adjust the length of the wristband terminal and fasten it with a disposable buckle; read the machine-readable identification unit through the mobile authorization terminal, and send the patient information to the background management server after successful reading to complete the binding; In-hospital operation and monitoring: When an operation involving the wristband is required, the mobile authorized terminal attempts to read the machine-readable identification unit; if the reading is successful, an operation request related to the one-time lock is initiated to the back-end management server based on the obtained identification information of the wristband terminal; if the reading fails, the mobile authorized terminal reads the permanent identifier, obtains the identification information of the wristband terminal, generates and reports abnormal event information to the back-end management server, triggering the early warning process executed by the anti-tamper monitoring module; Authorized adjustment: When an adjustment request is initiated and verified by the background authorization verification module, the current one-time buckle is cut off according to the authorization, the length of the wristband terminal is adjusted, and a new one-time buckle is replaced and tightened again. The adjustment completion confirmation is sent to the background management server through the mobile authorization terminal. Authorized disassembly: After a disassembly request is initiated and verified by the backend authorization verification module, a permission instruction generated by the backend is obtained. The one-time lock is cut and the wristband is removed according to the permission instruction. The disassembly completion confirmation is sent to the backend management server through the mobile authorization terminal.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Automatic monitoring and early warning of tamper-proof status are achieved. This invention forcibly associates the activation of the wristband chip's circuitry with the physical integrity of the latch, ensuring that any unauthorized damage will immediately disable the chip. The system can automatically detect this anomaly by reading the status and trigger an early warning, thus transforming tamper-proofing from a reliance on manual inspection into an automatically monitored proactive security mechanism, eliminating security blind spots.

[0017] 2. Ensured compliance and electronic traceability of disassembly procedures. Physical disassembly actions were deeply integrated into the electronic medical process. Disassembly could only be executed after receiving an authorization command generated by the system after automatically verifying discharge compliance conditions. This made disassembly a necessary, verifiable, and fully recorded critical step in the medical safety closed loop, solving the problems of disassembly actions being disconnected from compliance procedures and lacking records.

[0018] 3. This invention achieves standardized management and traceable nursing care. It defines wristband adjustment as a standardized nursing procedure requiring system authorization and recording of clinical reasons. Each adjustment requires authorization and buckle replacement, and the completion of the operation must be confirmed in the system. This ensures that the adjustment behavior, reason, executor, and time are all electronically recorded, transforming arbitrary and unrecorded physical operations into traceable and manageable nursing records, thus improving the level of management precision.

[0019] 4. Deep integration of the wristband's physical status with the information system was achieved. Through the hardware linkage between the chip and the locking mechanism, as well as the collaboration of the backend intelligent monitoring and authorization verification modules, the wristband was transformed from a simple identification carrier into an intelligent terminal capable of reflecting its own status (i.e., intact or malfunctioning) and requiring system authorization for key status changes, including disassembly and adjustment. Combined with backup visual identifiers, the reliability of status information collection was ensured, ultimately achieving system-wide monitoring of the wristband's entire lifecycle status, authorization-required operation, and full traceability.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0022] This embodiment provides an adjustable medical wristband system that combines anti-tampering and easy-to-disassemble functions, such as... Figure 1The diagram illustrates an intelligent solution that deeply integrates physical hardware and software management. The system includes a wristband terminal 100 worn on the patient's wrist, a disposable buckle 200 for securing the wristband terminal 100, a mobile authorization terminal 300 held by medical staff, and a back-end management server 400 deployed in the hospital's data center. The server connects to the mobile authorization terminal 300 and the hospital's existing information system (HIS) via a network, forming a complete closed loop for data processing and business control. This invention, through innovative hardware design, forcibly associates the electronic identification status of the wristband terminal 100 with the physical integrity of the disposable buckle 200, and utilizes the back-end management software system to electronically authorize, monitor, and record all operations involving changes in the buckle's status.

[0023] The main body of the wristband terminal 100 is made of medical-grade flexible material and has multiple sets of adjustment holes 103 to allow for length adjustment, thus accommodating different wrist circumferences and potential wrist swelling changes during hospitalization. The adjustment holes 103 are located at both ends of the wristband terminal 100, namely the starting end and the ending end, and are positioned correspondingly to form multiple fastening positions for adapting to different wrist circumferences. The adjustment holes 103 are used to cooperate with the disposable buckle 200, allowing for selection of different hole positions to accommodate different patient wrist circumferences.

[0024] Inside the wristband terminal 100, a circuit-state-dependent identification chip, serving as a machine-readable identification unit 101, is pre-embedded; a permanent identification 102 is provided on the outer surface of the wristband body. The circuit-state-dependent identification chip is implemented using a passive high-frequency RFID chip. This chip contains a crucial activation circuit, namely the chip's resonant antenna circuit, which pre-stores a globally unique identification code, i.e., the wristband ID. Whether the chip can be successfully activated and read by an external reader depends entirely on whether its internal activation circuit is in a conductive state.

[0025] The chip is embedded in the main body material of the wristband terminal 100 and has two electrical connection terminals. Starting from the first electrical connection terminal 104, a flexible first wire 105 is pre-embedded. This wire is laid along one side of the wristband body, and its end is connected to the first conductive part 106 on the inner wall of the adjustment hole 103 at the starting end of the wristband terminal 100. Similarly, starting from the second electrical connection terminal 107, a flexible second wire 108 is pre-embedded. This wire is laid along the other side of the wristband body, and its end is connected to the second conductive part 109 on the inner wall of the end adjustment hole 103 of the wristband terminal 100. In this embodiment, the first conductive part 106 and the second conductive part 109 are a ring-shaped conductive layer, i.e., a conductive ring.

[0026] The permanent identifier 102 is independent of the circuit state of the aforementioned chip and can be read under any circumstances, serving as a unique identifier for the wristband terminal 100. As a preferred embodiment, the permanent identifier 102 is a visually readable identifier, such as a QR code printed on the outer surface of the wristband terminal 100. The information encoded in this QR code is associated with or identical to an identifier stored in the chip, such as a wristband ID. In other embodiments, the permanent identifier 102 may also be a printed unique serial number, etc.

[0027] The disposable latch 200 comprises two interlocking and locking parts, which in this embodiment are a male connector 201 and a female connector 202, respectively. See below. Figure 3 The female connector 202 is initially inserted into the adjustment holes 103 at both ends of the wristband from the inner side of the wristband terminal 100, i.e., the side that contacts the wrist. The male connector 201 is subsequently inserted into the female connector 202 from the outer side of the wristband terminal and irreversibly locked to the female connector 202 by a one-way locking mechanism 203 at its front end, such as an elastic barb. This secures the wristband terminal 100 in a wearing state and prevents it from being pulled out by hand, providing basic physical anti-tamper protection. A key improvement of this invention lies in its electrical design. Two mutually insulated annular conductive areas are provided on the circumferential surface of the male connector 201 of the buckle, serving as the first conductive layer 204 and the second conductive layer 205, respectively. These two conductive layers are precisely designed so that, after the buckle is inserted into the wristband and locked, they can accurately correspond to the first conductive part 106 and the second conductive part 109 within the adjustment holes 103 at both ends of the wristband, respectively, achieving reliable electrical contact.

[0028] To further enhance tamper resistance, the first conductive layer 204 and the second conductive layer 205 are electrically connected within the buckle via an internal connecting wire 206. This internal connecting wire 206 is located at the male end 201 of the buckle, specifically within the end structure outside the wristband terminal 100 after wearing. This ensures that any meaningful cutting operation (cutting the male end 201) performed on the buckle to release the wristband will inevitably result in the internal connecting wire 206 being severed.

[0029] The activation circuit consists of the following parts connected in series, see [link to relevant documentation] Figure 2 Starting from the first electrical connection terminal 104 of the chip, the current flows through the first wire 105 to the first conductive part 106, then through contact conduction to the first conductive layer 204 of the latch, then through the connecting wire 206 inside the latch to the second conductive layer 205, then through contact conduction to the second conductive part 109 of the wristband, and finally through the second wire 108 back to the second electrical connection terminal 107 of the chip.

[0030] The physical integrity of the one-time latch 200 determines the on / off state of the activation circuit, which is achieved in the following ways: (1) Circuit conduction state, i.e., normal wearing. When the wristband is worn normally, select the adjustment hole 103 that fits the wrist, insert the one-time buckle 200 and lock it. During this process, the first conductive layer 204 and the second conductive layer 205 of the buckle will make reliable physical contact and electrical connection with the first conductive part 106 and the second conductive part 109 in the adjustment hole 103, respectively. At this time, the conductive layer of the buckle and its internal connecting wire 206 together form a conductive bridge, connecting the first wire 105 and the second wire 108 inside the wristband, thereby making the activation circuit conduction. The chip is in a state that can be normally sensed and read by the mobile authorized terminal 300.

[0031] (2) Circuit disconnection state, i.e., tamper protection trigger. When the latch is physically damaged, such as being cut by scissors, its internal connecting wire 206 will inevitably be cut. At this time, although the wires and conductive rings of the wristband may be intact, and the conductive layer of the latch may still be in contact with the conductive ring, the conductive bridge inside the latch is broken, and the entire series circuit forms an open circuit inside the latch, causing the activation circuit to be disconnected and the chip to immediately fail. Similarly, if the wristband body is cut, since the first wire 105 and the second wire 108 are respectively laid along both sides of the wristband, at least one of the wires will be broken, which will also cause the activation circuit to be permanently disconnected. In either case, the chip will be unreadable due to the incomplete circuit.

[0032] This design directly transforms the intuitive physical integrity breach event of a broken buckle or wristband into a clear, detectable status signal—whether the chip activation circuit is conducting—thus laying a solid hardware foundation for subsequent intelligent monitoring and early warning.

[0033] The mobile authorization terminal 300 serves as the user interface for medical personnel and is a smart mobile device with a dedicated application installed. It is used to read the machine-readable identification unit 101. If the reading is successful, based on the read identification information and the current business scenario, it initiates an operation request related to the disposable buckle 200 to the backend management server 400, such as a disassembly or adjustment request. If the reading fails, the mobile authorization terminal 300 prompts the user to read the permanent identification 102 on the wristband terminal 100, such as prompting the nurse to scan a QR code or enter a printed serial number. After successfully obtaining the identification information of the wristband terminal 100 carried by the permanent identification 102, the terminal generates an exception event message. This message includes at least the identification information of the wristband terminal 100 obtained through the permanent identification 102 and the event type of chip reading failure, and is immediately reported.

[0034] Preferably, the permanent identifier 102 is a visually readable identifier, such as a QR code. This visually readable identifier has unique identification information associated with the machine-readable identifier unit 101. When the mobile authorization terminal 300 cannot read the machine-readable identifier unit 101, it can automatically switch to scanning the visually readable identifier to obtain the identification information of the wristband terminal 100. This ensures that even if the main identifier chip completely fails, the tamper monitoring module can still accurately obtain the wristband's identity and trigger the warning process.

[0035] The backend management server 400 is the intelligent hub of the system, used to receive and process the operation requests or abnormal event information. The backend management server 400 includes an authorization verification module and an anti-tamper monitoring module, specifically including: (1) An authorization verification module is used to perform authorization verification on the operation request. The authorization verification includes verifying the operator's permissions, such as verifying login identity, and rule compliance. Only after the authorization verification is passed will a permission instruction be generated, authorizing the execution of the corresponding physical operation on the one-time lock 200. Verifying operator permissions and rule compliance specifically involves: Dismantling Authorization Verification: In response to a dismantling request, this module automatically calls an interface to retrieve and verify a pre-set set of discharge compliance conditions from the hospital's HIS system in real time. This set of conditions must include at least: the electronic discharge order has taken effect, medical expenses have been settled, and there are no pending medical orders. If all conditions are met, the verification passes.

[0036] Adjustment Authorization Verification: In response to an adjustment request, in addition to verifying operation permissions, the reason for adjustment must be selected in the application interface. The reason for adjustment must be selected from a predefined list of reasons, such as patient edema, discomfort from skin indentation, or preventative adjustment. This process transforms arbitrary physical adjustments into standardized nursing procedures that require recording clinical reasons.

[0037] Only after all the above verifications pass will the authorization verification module generate a one-time, time-limited electronic license instruction and send it to the mobile authorization terminal 300, thereby authorizing medical personnel to perform corresponding physical operations, such as cutting, on the one-time lock 200. The cutting point 207 of the lock is located at one end of the male connector 201.

[0038] Furthermore, the authorization verification module is also configured as a full-process status tracker. After the adjustment authorization verification passes, an adjustment event is recorded in the system log as "in progress"; upon receiving confirmation of adjustment completion from the mobile authorization terminal 300, the adjustment event status is updated to "completed," and the latch replacement is recorded as complete. After the disassembly authorization verification passes and a license instruction is generated, a disassembly event is recorded as "authorization issued"; upon receiving confirmation of disassembly completion, the disassembly event status is updated to "completed." This achieves fully electronic traceability of all critical operations.

[0039] (2) The anti-tamper monitoring module is used to monitor the reading status of the machine-readable identification unit 101 and execute an early warning process when abnormal event information is detected. The early warning process includes: after receiving the abnormal event information, the module immediately parses out the identification information of the wristband terminal 100. Then, it queries the system database to see if there is a valid authorization record for disassembly or adjustment operation corresponding to the wristband terminal 100. If there is no authorization record, the module determines that the reading failure is very likely due to unauthorized operation, and then automatically generates and issues an unauthorized disassembly early warning message, which is pushed to the relevant responsible person in real time through the message system. This mechanism realizes 24 / 7 automatic monitoring and early warning of the wristband status.

[0040] This embodiment also provides a medical wristband management method for an adjustable medical wristband system that combines anti-tampering and easy-to-remove functions, comprising the following steps: Wearing and binding: Adjust the length of the wristband terminal 100 and fasten it with the disposable buckle 200; read the machine-readable identification unit 101 through the mobile authorization terminal 300, and after successful reading, send patient information to the background management server 400 to complete the binding; In-hospital operation and monitoring: When an operation involving the wristband is required, the mobile authorized terminal 300 attempts to read the machine-readable identification unit 101; if the reading is successful, based on the obtained identification information of the wristband terminal 100, an operation request related to the one-time lock 200 is initiated to the backend management server 400; if the reading fails, the mobile authorized terminal 300 reads the permanent identifier 102, obtains the identification information of the wristband terminal 100, generates and reports abnormal event information to the backend management server 400, triggering the early warning process executed by the anti-tamper monitoring module; Authorized adjustment: When an adjustment request is initiated and verified by the background authorization verification module, the current disposable buckle 200 is cut off according to the authorization, the length of the wristband terminal 100 is adjusted, and a new disposable buckle 200 is replaced and tightened again. The adjustment completion confirmation is sent to the background management server 400 through the mobile authorization terminal 300. Authorized disassembly: After a disassembly request is initiated and verified by the background authorization verification module, a permission instruction generated by the background is obtained. The one-time lock 200 is cut and the wristband is removed according to the permission instruction. The disassembly completion confirmation is sent to the background management server 400 through the mobile authorization terminal 300.

[0041] This embodiment also provides an adjustable medical wristband for the aforementioned adjustable medical wristband system that combines anti-tampering and easy-to-remove functions, comprising: The wristband terminal 100 has an adjustable length and is equipped with a circuit state-dependent identification chip and a permanent identification chip 102, the chip containing an activation circuit; A one-time locking buckle 200 is used to secure the wristband terminal 100 in an adjustable tightness while it is worn. The physical integrity of the one-time latch 200 determines the on / off state of the activation circuit.
