Abstract
Description
Technical Field
[0001] This invention belongs to the field of adult incontinence care products and intelligent monitoring technology, specifically relating to an early warning control method, system and computer-readable storage medium for anti-self-removing adult diapers, and particularly to an early warning control method based on the cooperation of a reusable detection component and a replaceable disposable absorbent component, which jointly judges the waistband locking state, authorized unlocking state, waistband stress state and zone tearing state. Background Technology
[0002] Adult diapers are widely used in elderly care, post-operative care, incontinence care, and care for people with cognitive impairment. For some users with declining cognitive function, low behavioral cooperation, or high nighttime care needs, adult diapers may be pulled open, the waistbands torn, the side wings ripped, or forcibly removed after being worn. This leads to absorbency failure, contamination of the care environment, and increased workload for caregivers in checking and changing diapers. Therefore, incorporating status monitoring and remote reminder functions into adult diapers represents a direction for the intelligent development of care products.
[0003] Existing technologies already include solutions for detecting and triggering alarms when absorbent materials become loose or are removed. For example, prior art document CN101222892B discloses a method for detecting when absorbent materials become loose or fall off the body. This method can detect changes in the absorbent material relative to the body or a fixation system and generate an alarm signal when it becomes loose or falls off. It is suitable for care scenarios involving children or adults with incontinence or dementia. This type of technology can alert caregivers when absorbent materials fall off or become abnormally positioned, providing a certain level of care reminder.
[0004] However, existing solutions mostly focus on "alarms after loosening" or "alarms after status changes," failing to adequately consider the complex situations encountered in the actual use of adult diapers. First, caregivers may open the waistband or latches during normal diaper changes. If the system cannot recognize whether this operation is authorized care, false alarms are likely to occur during normal care. Second, some users do not directly open the waistband locking structure but instead bypass the latches and tear at the base of the waistband or the side edges; if only the latch opening / closing status is detected, it is difficult to promptly identify the torn area. Third, turning over, sitting up, clothing pulling, or caregiver movement may also cause short-term fluctuations in waistband pressure. If only tension threshold alarms are used, normal changes in body position may be misinterpreted as diaper loosening.
[0005] Furthermore, fixing the control module, communication module, power module, and various detection components all onto a disposable diaper would increase the cost per piece and cause the electronic components to be discarded along with the disposable item, which is not conducive to practical applications in daily continuous care scenarios. Therefore, a warning control method suitable for two-part adult diapers is needed, in which reusable detection components can handle authorization identification, force detection, latch status detection, control, and communication functions, while replaceable disposable absorbent components can handle absorption functions and low-cost zone tear sensing functions. The usability and targeting of the warning can be improved through connection confirmation, authorization time window, timing matching, zone tear judgment, and short-term fluctuation filtering. Summary of the Invention
[0006] The purpose of this invention is to provide a warning control method, system and storage medium for anti-self-removal adult diapers, so as to reduce the cost of disposable products while distinguishing between normal care unlocking, unauthorized removal and short-term force fluctuations.
[0007] To achieve the above technical objectives, the present invention provides the following technical solution. In a first aspect, the present invention provides a pre-warning control method for an anti-self-removal adult diaper, applied to an adult diaper. The adult diaper includes a reusable detection component and a replaceable disposable absorbent component. The reusable detection component includes an authorization trigger unit, a waistband force detection unit, a locking status detection unit, a control module, and a communication module. The replaceable disposable absorbent component includes a diaper body and a partition tear sensing unit. The reusable detection component is detachably connected to the replaceable disposable absorbent component, and reads the status of the partition tear sensing unit after connection. When the waistband locking structure of the adult diaper is unlocked by a dedicated unlocking tool, an authorization trigger signal is generated. The pre-warning control method includes:
[0008] S1. After the reusable detection component is connected to the replaceable disposable absorption component and the waistband locking structure is in a closed state, the initial tension of the waistband, the initial state of the buckle, the initial state of the partition tear sensing unit, and the corresponding reference time are collected and recorded.
[0009] S2. When an authorization trigger signal is detected, an authorization unlocking time window is generated, and within the authorization unlocking time window, the buckle status change signal and waist tension change signal are continuously collected.
[0010] S3. Perform timing matching on the authorization trigger signal, the latch status change signal and the latch opening signal. When the three meet the preset sequence and all fall within the authorization unlocking time window, it is determined to be normal nursing unlocking.
[0011] S4. When no authorized trigger signal is detected, or the buckle opening signal is earlier than the authorized trigger signal, or the authorized trigger signal, the buckle status change signal and the buckle opening signal do not meet the preset sequence, the unauthorized detachment behavior is judged based on the waist tension peak value, tension duration, buckle displacement and the state change of the partition tearing sensing unit.
[0012] S5. Based on the judgment result of unauthorized detachment behavior, filter the short-term force fluctuation, and after filtering, generate an early warning level according to the area corresponding to the partition tearing sensing unit, the peak waist tension and the buckle displacement, and send the early warning information to the nursing terminal through the communication module.
[0013] Specifically, in step S1, before entering the early warning monitoring, the control module detects the connection status between the reusable detection component and the replaceable disposable absorption component; when the connection status is detected to meet the preset connection conditions, the initial status of the partition tearing sensing unit is read; when the connection status does not meet the preset connection conditions, an installation abnormality prompt is output, and the unauthorized removal behavior judgment is suspended.
[0014] Specifically, the reusable detection component and the replaceable disposable absorption component are detachably connected by one or more of the following methods: snap-fit, plug-in, clamp, magnetic attraction, conductive contact crimping, or flexible ribbon cable plug-in; after connection, the control module reads the status of the partition tear sensing unit by contact conduction status, interface impedance, port level, or area encoding.
[0015] Specifically, the replaceable disposable absorbent component is provided with consumable identification information, which includes one or more of the following: identification resistor, conductive coding area, QR code, radio frequency identification tag or interface port code; in step S1, the control module reads the consumable identification information and calls the waist tension threshold, buckle displacement threshold, partition tearing identification rule or warning level rule corresponding to the type of replaceable disposable absorbent component based on the reading result.
[0016] Specifically, in step S2, the authorization trigger signal includes one or more of the following: an electrical connection signal, a magnetic induction signal, a pressure trigger signal, a radio frequency identification signal, or a proximity sensing signal triggered by a dedicated unlocking tool; when the duration of the authorization trigger signal reaches a preset authorization confirmation time and the signal strength or identification result meets the preset authorization conditions, the authorization unlocking time window is generated.
[0017] Specifically, the partition tear sensing unit is a conductive ink line, conductive fiber line, thin film conductive line, or conductive nonwoven fabric line disposed on the replaceable disposable absorbent assembly; the partition tear sensing unit includes at least two detection partitions corresponding to the waistband locking area, the waistband root area, and the diaper side wing edge area, and each detection partition corresponds to a different access port, identification resistance value, or area code.
[0018] Specifically, when the detection zone corresponding to the waistband base area or the side wing edge area of the diaper is disconnected, experiences a sudden change in resistance, changes in conduction status, or has an abnormal area coding, and no authorized trigger signal is detected, it is preferentially determined to be a tearing and detachment behavior that bypasses the waistband locking structure; when the detection zone corresponding to the waistband locking area changes status and there is an abnormal buckle displacement at the same time, it is determined to be a forced detachment behavior targeting the waistband locking structure.
[0019] Specifically, in steps S4 and S5, the unauthorized detachment behavior judgment and short-term force fluctuation filtering include:
[0020] When the peak waist tension exceeds the preset stretching threshold and the tension duration exceeds the preset duration, a stretching anomaly marker is generated;
[0021] When the latch displacement exceeds the unauthorized displacement threshold and is not in a normal care unlocking state, a latch abnormality flag is generated.
[0022] When the state of the partition tear sensing unit changes, a tearing anomaly marker is generated;
[0023] When there is only a pulling abnormality mark, and the tension duration does not exceed the preset filter time, and there are no locking abnormality mark or tearing abnormality mark, it is determined to be a short-term force fluctuation caused by changes in body position, nursing movement or occasional traction, and no unauthorized detachment warning is generated.
[0024] In a second aspect, the present invention also provides an early warning control system for anti-self-removing adult diapers, used to implement the early warning control method for anti-self-removing adult diapers described in the first aspect, the early warning control system comprising:
[0025] The connection and status acquisition module is used to execute step S1;
[0026] The authorization identification module is used to execute step S2;
[0027] The timing matching module is used to execute step S3;
[0028] The exception detection module is used to execute step S4;
[0029] The early warning output module is used to execute step S5.
[0030] Thirdly, the present invention also provides a computer-readable storage medium having a computer program or instructions stored thereon, wherein when the computer program or instructions are executed by a processor, the method for early warning control of anti-self-removing adult diapers described in the first aspect is implemented.
[0031] This invention employs a structure combining a reusable detection component and a replaceable disposable absorbent component. This allows the control module, communication module, power module, authorization trigger unit, waist force detection unit, and buckle status detection unit to be reused, while the zone tearing sensing unit is replaced along with the disposable absorbent component. This reduces the cost per use and minimizes the discarding of electronic components as consumables. In terms of control method, this invention first confirms the connection status of the two components and collects a baseline status. Upon detecting an authorization trigger signal, an authorization unlocking time window is generated. Normal care unlocking is determined by timing matching of the authorization trigger signal, buckle status change signal, and buckle opening signal. For cases where normal care unlocking conditions are not met, unauthorized detachment behavior is further determined by combining the waist tension peak, tension duration, buckle displacement, and zone tearing status change. Short-term force fluctuations are filtered out, thereby reducing false alarms caused by normal care and changes in body position. Simultaneously, it can output warning levels and tearing areas for timely handling by nursing staff. Attached Figure Description

[0036] The embodiments of the present invention will now be described with reference to the accompanying drawings. These embodiments are for illustrative purposes only and do not limit the scope of protection of the present invention. Without departing from the scope of the claims, those skilled in the art can adaptively adjust the form of the detection element, interface structure, threshold parameters, and communication method according to the adult diaper model, waist size, nursing scenario, and communication conditions.
[0037] I. Overall Structure
[0038] like Figure 1 As shown, this embodiment provides a pre-warning control method for anti-self-removal adult diapers, applied to adult diapers. The adult diaper includes a replaceable disposable absorbent component 1 and a reusable detection component 2. The replaceable disposable absorbent component 1 mainly undertakes absorption, adhesion, and low-cost tear state sensing functions; the reusable detection component 2 mainly undertakes authorization recognition, waist circumference force detection, buckle status detection, control calculation, communication, and power supply functions. Through this two-part structure, the control module, communication module, power supply module, and main detection elements can be reused, while the absorbent core, skin-friendly layer, leak-proof bottom layer, and low-cost partition tear sensing circuitry can be replaced along with the disposable absorbent component.
[0039] 1.1 Replaceable disposable absorbent components
[0040] The replaceable disposable absorbent assembly 1 includes a diaper body 11, an absorbent core 12, a consumable interface area 13, a consumable identification unit 14, and a zoned tear sensing unit 4. The diaper body 11 can adopt a structure commonly used in adult incontinence products, including a liquid-permeable surface layer, a diversion layer, an absorbent core 12, a leak-proof bottom layer, a waistband, and side wings. The absorbent core 12 is used to absorb urine or other excretory fluids, and its specific layered structure can be made of fluff pulp, superabsorbent polymer, composite absorbent paper, dust-free paper, or a combination thereof.
[0041] 1.1.1 Consumables Interface
[0042] The consumable interface area 13 is located on the waist, side, or other easily accessible position of the replaceable disposable absorbent assembly 1. The consumable interface area 13 is used for detachable connection to the detection interface 27 of the reusable detection assembly 2, enabling the reusable detection assembly 2 to read the status of the partition tear sensing unit 4. The consumable interface area 13 may include conductive contacts, flexible plug-in terminals, crimp terminals, conductive latches, magnetic positioning elements, or flexible cable ends. To ensure connection stability, the consumable interface area 13 may be provided with positioning holes, positioning grooves, crimping marks, or orientation-correcting structures to reduce assembly errors.
[0043] 1.1.2 Consumables Identification
[0044] The consumable identification unit 14 is used by the control module 24 to identify the type of the currently connected replaceable disposable absorbent assembly 1. The consumable identification unit 14 can use one or more of the following: identification resistor, conductive coding area, QR code, RFID tag, or interface port coding. Different models of replaceable disposable absorbent assemblies 1 can correspond to different waist circumference sizes, absorption levels, or circuit layouts of the partition tear sensing unit 4. Therefore, before entering formal monitoring, the control module 24 reads the consumable identification information and calls the corresponding waist circumference tension threshold, buckle displacement threshold, partition tear identification rule, and warning level rule.
[0045] 1.1.3, Zoned tearing sensor
[0046] The partition tear sensing unit 4 is disposed on the replaceable disposable absorbent assembly 1. It can employ conductive ink circuitry, conductive fiber circuitry, thin-film conductive circuitry, conductive non-woven fabric circuitry, or other breakage detection structures that can be replaced with the disposable absorbent assembly at low cost. The partition tear sensing unit 4 includes at least two detection partitions. Preferably, the partition tear sensing unit 4 includes a waistband locking area detection partition 41, a waistband base area detection partition 42, and a diaper side wing edge area detection partition 43. Each detection partition corresponds to a different access port, identification resistance value, or area code, enabling the control module 24 to identify the corresponding tear area when it detects a disconnection, a sudden change in resistance value, a change in conduction state, or an abnormal area code.
[0047] 1.2 Reusable detection components
[0048] The reusable detection component 2 has a detachable structure and can be configured as a small box, a flexible waistband, a clamp-type detection element, a waistband fastener, or a modular component that can be wiped clean and disinfected. The reusable detection component 2 includes an authorization trigger unit 21, a waistband force detection unit 22, a buckle status detection unit 23, a control module 24, a communication module 25, a power supply module 26, and a detection interface 27.
[0049] 1.2.1 Authorization Trigger Unit
[0050] The authorization trigger unit 21 generates an authorization trigger signal when the waist locking structure 3 is unlocked by a dedicated unlocking tool. The authorization trigger signal can be one or more of the following: an electrical connection signal, a magnetic induction signal, a pressure trigger signal, a radio frequency identification signal, or a proximity sensing signal. The authorization trigger signal indicates that the current unlocking action originates from a dedicated unlocking tool held or used by a caregiver, and is not an unauthorized removal action caused by the user pulling, prying, or tearing.
[0051] 1.2.2 Waist Circumference Stress Detection Unit
[0052] The waist circumference force detection unit 22 is used to detect changes in force on the waist circumference locking structure 3 or its adjacent area. The waist circumference force detection unit 22 can be a flexible thin-film pressure sensor, tensile strain sensor, piezoresistive sensing sheet, flexible resistive strip, or other flexible force detection components suitable for wearable scenarios. Since the waist circumference force detection unit 22 is located on the reusable detection component 2, it can use a more stable sensing element and does not need to be discarded with each diaper.
[0053] 1.2.3 Locking Status Detection Unit
[0054] The latch status detection unit 23 is used to detect changes in the state of the waistband locking structure 3. These changes include a closed state, a released state, an open state, or a displacement change state. The latch status detection unit 23 can employ a microswitch, a Hall element, a flexible conductive plate, a displacement trigger plate, or a proximity sensor. The latch status detection unit 23 is not required to output a high-precision continuous displacement value; in one embodiment, as long as it can distinguish between the locked, released, and open states, it meets the implementation requirements of this method. In another embodiment, the latch status detection unit 23 can output an approximate displacement amount for subsequent warning level determination.
[0055] 1.2.4 Control Module
[0056] The control module 24 can be a low-power microcontroller, a flexible circuit control unit, or a detachable detection controller. The control module 24 is connected to the authorized trigger unit 21, the waist circumference force detection unit 22, the buckle status detection unit 23, the communication module 25, the power supply module 26, and the detection interface 27. The control module 24 reads the status of the partition tear sensing unit 4 and the consumable identification unit 14 on the replaceable disposable absorbent assembly 1 through the detection interface 27, and executes the early warning control method of this embodiment.
[0057] 1.2.5 Communication Module
[0058] The communication module 25 can use Bluetooth, Bluetooth Low Energy, Wi-Fi, NB-IoT, LoRa, cellular communication, or near-field relay communication to send warning information to the nursing terminal 5. The nursing terminal 5 can be a nursing staff's mobile phone, a nurse station receiver, a nursing platform in an elderly care institution, a ward nursing terminal, or a home care reminder terminal. The power module 26 can be powered by a rechargeable battery, a button battery, a flexible battery, or an external charging interface. The housing of the reusable detection component 2 preferably has a waterproof, sweatproof, and easy-to-wipe surface so that it can continue to be used after the disposable absorption component is replaced.
[0059] 1.3 Waistband Locking Structure
[0060] The waistband locking structure 3 can be mounted on the reusable detection component 2, or it can be formed jointly by the reusable detection component 2 and the replaceable disposable absorbent component 1. For example, the reusable detection component 2 can serve as a waistband locking fastener or locking clamp, connected to the waist patch or interface area of the disposable absorbent component 1; alternatively, a portion of the waistband locking structure 3 can be mounted on the disposable absorbent component 1, and another portion on the reusable detection component 2. The specific mechanical form of the waistband locking structure 3 can be fastening, insertion, clamping, magnetic assisted positioning, or other locking methods suitable for nursing products. This embodiment is not limited to a specific mechanical shape, as long as it can generate an authorized trigger signal when unlocked by a dedicated unlocking tool, and enable the control module 24 to recognize the change in the locking state.
[0061] II. Specific Implementation Plan for Early Warning and Control Methods
[0062] like Figure 2 As shown, the early warning control method for anti-self-removing adult diapers in this embodiment includes the following steps.
[0063] 2.1 S1 Connection Confirmation and Baseline Status Acquisition
[0064] After the reusable detection component 2 is connected to the replaceable disposable absorbent component 1 and the waistband locking structure 3 is in a closed state, the control module 24 collects and records the initial tension of the waistband, the initial state of the buckle, the initial state of the partition tear sensing unit 4, and the corresponding reference time.
[0065] Before entering formal early warning monitoring, the control module 24 first detects the connection status between the reusable detection component 2 and the replaceable disposable absorption component 1 through the detection interface 27. The connection status can be determined by contact continuity status, interface impedance, port level, insertion signal, or area code reading results. When the connection status meets the preset connection conditions, the control module 24 reads the initial state of the partition tearing sensing unit 4; when the connection status does not meet the preset connection conditions, the control module 24 outputs an installation abnormality prompt and suspends the execution of unauthorized removal behavior judgment.
[0066] For example, when the partition tear sensing unit 4 uses conductive circuits, the control module 24 can detect the loop impedance of each detection partition. If the loop impedance is within the preset effective range, the connection between the detection interface 27 and the consumable interface area 13 is considered reliable; if the impedance of any detection partition is open circuit or exceeds the preset range, it may indicate that the connection is not in place, the consumable interface is contaminated, the circuit is damaged, or the component model is incompatible. At this time, the control module 24 can send an installation abnormality prompt to the nursing terminal 5 through the communication module 25, or prompt the nursing staff to reinstall through the indicator light, buzzer, or vibration on the reusable detection component 2.
[0067] After the connection status is confirmed, the control module 24 reads the information from the consumable identification unit 14. If the consumable identification information corresponds to a preset model, the control module 24 calls the corresponding parameters. For example, the waist tension threshold and buckle displacement threshold of adult large-size diapers and adult medium-size diapers can be different; the layout of the partition tear-sensing circuit of daytime and nighttime diapers can also be different. If consumable identification fails, the control module 24 can use the default parameters or output a consumable identification error prompt, which needs to be confirmed by the caregiver before resuming monitoring.
[0068] When the waist locking structure 3 closes, the buckle state detection unit 23 detects that the waist locking structure 3 has changed from an open state to a closed state and sends a closed state signal to the control module 24. After receiving the closed state signal, the control module 24 collects waist force data within a preset stabilization period to determine the initial waist tension reference. The preset stabilization period can be 5 to 30 seconds. In one embodiment, the preset stabilization period is 10 seconds, and the waist force detection unit 22 collects waist tension data at a frequency of 5 to 20 times per second.
[0069] Control module 24 can determine the initial waist tension reference as follows:
[0070]
[0071] In the formula, As the initial tension reference for waist circumference, For the first time within the preset stable period The waist tension value collected this time. This represents the effective number of samples taken within a stable period. To reduce the impact of individual outlier samples on the baseline value, the maximum and minimum values can be removed first, and then the average of the remaining samples can be used as the initial waist circumference tension baseline.
[0072] Simultaneously, the control module 24 reads the initial state of the latch state detection unit 23 and records it as the initial state of the latch. If the latch state detection unit 23 can output a displacement value, the initial displacement position of the latch is recorded; if the latch state detection unit 23 only outputs a state quantity, the latch closing state is recorded as the initial state.
[0073] The control module 24 also reads the initial state of the partition tear sensing unit 4 through the detection interface 27. For conductive detection partitions, the initial state can be the conduction state and initial resistance value of each detection partition; for coded detection partitions, the initial state can be the area coding reading result of each detection partition; for port-type detection partitions, the initial state can be whether each port is connected. If any detection partition is in an abnormal state during the baseline acquisition stage, the control module 24 can output a consumable abnormality prompt to remind nursing staff to check whether the disposable absorbent component 1 is damaged or properly connected.
[0074] The function of S1 is to confirm the reliability of the connection between the two components and to establish a baseline for the current wearing status. Since different users have different waist sizes, wearing tightness, and diaper models, using an individualized baseline can reduce the error caused by fixed threshold judgments.
[0075] 2.2 Generation of S2 Authorization Unlock Time Window
[0076] When an authorization trigger signal is detected, the control module 24 generates an authorization unlocking time window and continuously collects the buckle status change signal and waist tension change signal within the authorization unlocking time window.
[0077] The authorization trigger signal is generated by the authorization trigger unit 21. The authorization trigger signal is associated with the action of the special unlocking tool to release the waist belt locking structure 3. When the caregiver uses the special unlocking tool to unlock the waist belt locking structure 3, the authorization trigger unit 21 generates the authorization trigger signal; when the user pulls, pries, or tears open the waist belt locking structure 3, a qualified authorization trigger signal is usually not generated.
[0078] The authorization trigger signal can be an electrical connection signal, a magnetic induction signal, a pressure trigger signal, a radio frequency identification (RFID) signal, or a proximity sensing signal. For example, a dedicated unlocking tool can trigger the authorization trigger unit 21 to output an identifiable signal by approaching, inserting, pressing, or moving close to the reusable detection component 2. After receiving the authorization trigger signal, the control module 24 can first perform authorization confirmation. Authorization confirmation can include duration confirmation, signal strength confirmation, or identification result confirmation. When the duration of the authorization trigger signal reaches the preset authorization confirmation time, and the signal strength or identification result meets the preset authorization conditions, the control module 24 generates an authorization unlocking time window. If the authorization trigger signal is a short-term interference signal and the duration does not reach the preset authorization confirmation time, no authorization unlocking time window is generated.
[0079] The authorized unlocking time window is used to define the time range within which a normal nursing unlocking action should occur. The authorized unlocking time window can range from 3 seconds to 20 seconds. In one embodiment, the authorized unlocking time window is set to 10 seconds. A time window that is too short may lead to misjudgment if the caregiver's action is slightly slow; a time window that is too long may reduce the timeliness of identifying unauthorized behavior. Therefore, the authorized unlocking time window can be set according to the nursing scenario and the operation mode of the waistband locking structure 3.
[0080] Within the authorized unlocking time window, the control module 24 continuously collects the buckle status change signal and the waist tension change signal. The buckle status change signal is used to determine whether the waist locking structure 3 has changed from the locked state to the released state and whether it has entered the open state; the waist tension change signal is used to determine whether there is abnormal pulling during the unlocking process.
[0081] 2.3 Timing Matching of S3 Authorization Signal and Lock Status
[0082] The control module 24 performs timing matching on the authorization trigger signal, the latch status change signal, and the latch opening signal. When the three signals meet the preset sequence and all fall within the authorization unlocking time window, it is determined to be a normal care unlock.
[0083] like Figure 3 As shown, the typical timing sequence for unlocking during normal care is as follows: first, an authorization trigger signal is generated; then, a buckle state change signal appears; and finally, a buckle open signal appears. The buckle state change signal can be a signal indicating that the waistband locking structure 3 has changed from a locked state to a released state, or it can be a signal indicating that the buckle displacement has begun to change. The buckle open signal can be a signal indicating that the waistband locking structure 3 is fully open, or it can be a signal generated when the buckle displacement reaches the open threshold.
[0084] Let the authorized trigger signal be generated at time . The time when the latch status change signal is generated is The latch open signal is generated at the following time. The end time of the authorized unlocking time window is In one implementation, normal care unlocking requires the following conditions to be met:
[0085]
[0086] and:
[0087]
[0088] In the formula, The maximum permissible interval between the authorization trigger signal and the latch status change signal. This is the maximum allowable interval between the latch status change signal and the latch open signal. The above parameters can be set according to the waistband locking structure 3 and nursing operation habits. For example, It can be set to 3 seconds. It can be set to 5 seconds.
[0089] If the latch opening signal appears before the authorized trigger signal, it indicates that the waist belt locking structure 3 may have been pulled open or damaged without authorization, and the control module 24 will not determine it as normal nursing unlocking. If no latch status change signal appears for a long time after the authorized trigger signal appears, or no latch opening signal appears for a long time after the latch status change signal appears, it indicates that the current action does not conform to the normal nursing operation process, and the control module 24 will not determine it as normal nursing unlocking, but will enter the unauthorized disassembly behavior judgment.
[0090] The timing matching of S3 does not simply shut down the alarm after the authorized trigger signal appears. Instead, it requires that the authorized trigger, latch release, and latch opening occur in a preset sequence, all within the authorized unlocking time window. This prevents subsequent abnormal pulling behavior from being mistaken for normal nursing behavior if the authorized trigger unit 21 is accidentally triggered.
[0091] After a normal nursing unlock is determined, the control module 24 does not trigger a tearing warning, but can record the nursing release event. The nursing release event can include the authorization trigger time, latch opening time, disposable absorbent component type, and reusable detection component number. In application scenarios requiring nursing records, the nursing release event can be sent to the nursing terminal 5 or the nursing management platform via the communication module 25.
[0092] 2.4 Judgment of S4 Unauthorized Removal Behavior
[0093] When no authorized trigger signal is detected, or the buckle opening signal is earlier than the authorized trigger signal, or the authorized trigger signal, the buckle status change signal and the buckle opening signal do not meet the preset sequence, the control module 24 judges the unauthorized detachment behavior based on the waist tension peak value, tension duration, buckle displacement and the state change of the partition tearing sensing unit 4.
[0094] In this embodiment, unauthorized detachment is not determined by a single signal, but by a combination of factors including the force applied to the waistband, the status of the latches, and the state of tearing in the sectional area. This allows for the differentiation of different situations, such as changes in body position, nursing care movements, occasional traction, attempts to open the latches, and tearing the side wings to bypass the latches.
[0095] Control module 24 based on real-time waist tension relative to the initial tension benchmark of waist circumference The difference determines the amount of tension change:
[0096]
[0097] Within a continuous detection window, control module 24 determines the peak waist tension:
[0098]
[0099] In the formula, This represents the peak tension relative to the initial waist circumference tension baseline. If... If the pulling threshold is exceeded and the duration of exceeding the threshold reaches the preset duration, a pulling abnormality marker will be generated.
[0100] The preset tensile threshold can be set according to the model of the replaceable disposable absorbent component 1, the waistband material, and the wearer. For example, for a typical adult diaper sample, the preset tensile threshold can be set to 8N to 20N; the preset duration can be set to 0.5 seconds to 3 seconds. In one embodiment, the preset tensile threshold is 12N, and the preset duration is 1.0 second.
[0101] The buckle status detection unit 23 outputs the status or displacement of the waistband locking structure 3. When the buckle displacement exceeds the unauthorized displacement threshold and the current state is not in normal care unlocking state, the control module 24 generates a buckle abnormality flag. If the buckle status detection unit 23 only outputs a status value, a buckle abnormality flag is generated when the waistband locking structure 3 changes from the locked state to the released state or the open state without detecting an authorized trigger signal. If the buckle status detection unit 23 outputs a displacement value, the control module 24 compares the real-time displacement value with the initial displacement position of the buckle, and generates a buckle abnormality flag when the displacement difference exceeds the unauthorized displacement threshold.
[0102] When the zone tear sensing unit 4 is disconnected, experiences a sudden change in resistance, a change in conduction state, or an abnormal zone coding, the control module 24 generates a tearing abnormality flag. Since the zone tear sensing unit 4 is mounted on the replaceable disposable absorption assembly 1, it can be replaced along with the consumable using a low-cost conductive circuit. The zone tear sensing unit 4 does not need to be designed for long-term repeated use; it only needs to remain detectable during the current use of the disposable absorption assembly.
[0103] When the detection zone 42 at the base of the waistband or the detection zone 43 at the edge of the diaper side wings changes state and no authorized trigger signal is detected, the control module 24 prioritizes determining it as a tearing and detachment behavior that bypasses the waistband locking structure 3. This is because such behavior may not be achieved by opening the waistband locking structure 3, but rather by tearing open the diaper side wings or the base of the waistband. Relying solely on the locking status detection may not be able to identify such behavior in a timely manner.
[0104] When the detection zone 41 of the waistband locking area changes state and there is a buckle abnormality mark, the control module 24 determines that it is a forced disassembly behavior against the waistband locking structure 3.
[0105] In one implementation, the control module 24 determines whether unauthorized unloading behavior exists according to the following rules:
[0106] When an abnormal tearing mark is present, it is determined that there has been unauthorized removal behavior;
[0107] When there is an abnormal lock mark and the device is not in the normal care unlocking state, it is determined that there is an unauthorized removal behavior.
[0108] When there is a pulling abnormality mark, and at the same time there is a locking abnormality mark or tearing abnormality mark, it is determined that there is an unauthorized detachment behavior;
[0109] When only the abnormal tension marker exists, a short-term force fluctuation filtering process is initiated. If the abnormal conditions are still met after filtering, it is determined that there is unauthorized detachment behavior.
[0110] 2.5 S5 Short-Time Force Filtering and Graded Early Warning Output
[0111] Based on the judgment result of unauthorized removal behavior, the control module 24 filters the short-term force fluctuations, and after filtering, generates a warning level based on the area corresponding to the partition tearing sensing unit 4, the peak waist tension and the buckle displacement, and sends the warning information to the nursing terminal 5 through the communication module 25.
[0112] Adult diapers may be affected by various non-removal factors during actual use, such as the user turning over, sitting up, caregivers moving the body, clothing snagging, or contact with bed rails. These situations may cause a short-term increase in waist tension, but usually do not involve the opening of the buckle or changes in the state of the zone tearing sensing unit 4. Therefore, when the peak waist tension exceeds the preset tearing threshold, but the tension duration does not exceed the preset duration, and no buckle abnormality mark or tearing abnormality mark is generated, the control module 24 determines it as a short-term force fluctuation caused by changes in body position, caregiver movement, or occasional traction, and does not generate an unauthorized removal warning.
[0113] In one implementation, the control module 24 can also set an observation delay period. For example, after detecting a short-term tension peak, observation continues for 2 to 5 seconds. If no buckle abnormality mark or tearing abnormality mark appears during the observation delay period, the short-term stress event is discarded; if a buckle abnormality mark or tearing abnormality mark appears during the observation delay period, the unauthorized detachment behavior judgment is re-entered.
[0114] The control module 24 can classify the warning levels into three levels: alert, intervention, and emergency. The alert level indicates an abnormal force or a slight risk of detachment, but no clear opening or tearing has yet occurred. The intervention level indicates a more definite unauthorized detachment, such as detecting a buckle displacement exceeding the unauthorized displacement threshold when not in a normal care unlocking state. The emergency level indicates tearing, breakage, or multiple signal anomalies, such as detecting a disconnection, sudden resistance change, conduction status change, or area coding anomaly in any detection zone, or simultaneously detecting excessive waist tension and excessive buckle displacement.
[0115] The warning information may include the reusable detection component number, the type of replaceable disposable absorbent component, the warning level, the warning time, the buckle status, the tear area, the peak waist tension, and the communication status. For data scenarios that require simplified transmission, the communication module 25 may also send only the warning level, the tear area, and the component number, with detailed data stored in the control module 24 or the nursing terminal 5.
[0116] After receiving an alert, nursing terminal 5 can notify caregivers to check via sound, vibration, pop-up window, indicator light, or platform message. If nursing terminal 5 is connected to the elderly care institution's platform or ward nursing system, it can also write the alert information into the nursing record.
[0117] III. Examples
[0118] 3.1 Example 1: Connection Confirmation and Early Warning Control of Two-Part Adult Diapers
[0119] This embodiment uses a two-part adult diaper sample. The replaceable disposable absorbent assembly 1 includes a diaper body 11, an absorbent core 12, a consumable interface area 13, a consumable identification unit 14, and a zone tear sensing unit 4. The zone tear sensing unit 4 uses conductive ink circuitry to form three detection zones: a waistband locking area detection zone 41, a waistband base area detection zone 42, and a diaper side wing edge area detection zone 43. The three detection zones extend to the consumable interface area 13.
[0120] The reusable detection component 2 is a clamp-type waist circumference detection component, including an authorization trigger unit 21, a waist circumference force detection unit 22, a buckle status detection unit 23, a control module 24, a communication module 25, a power module 26, and a detection interface 27. The detection interface 27 is connected to the consumable interface area 13 via conductive contact crimping. The communication module 25 uses Bluetooth Low Energy and connects to the care terminal 5. The consumable identification unit 14 uses a resistor identification method; the control module 24 reads the identification resistor value through the detection interface 27 and calls the corresponding threshold parameter.
[0121] The control module 24 executes according to the following parameters: the preset stable period is 10 seconds; the waist tension sampling frequency is 10Hz; the authorization confirmation time is 0.5 seconds; the authorization unlocking time window is 10 seconds; the maximum allowable interval between the authorization trigger signal and the buckle status change signal is 3 seconds; the maximum allowable interval between the buckle status change signal and the buckle opening signal is 5 seconds; the preset tensile threshold is 12N; and the preset duration is 1.0 second.
[0122] The test was conducted using a waist circumference mannequin and a nursing staff member. The replaceable disposable absorbent component 1 was secured to the waist circumference mannequin in the normal wearing manner, while the reusable testing component 2 was clamped in the waist circumference locking area and pressed against the consumable interface area 13. Test events included the following six categories:
[0123] Category A: Component connection error. Detection interface 27 is not fully crimped into consumable interface area 13;
[0124] Category B: Normal care unlocking. Caregivers use specialized unlocking tools to open the waist belt locking structure 3;
[0125] Category C: Postural Change Simulation. Simulation of turning over, sitting up, or nursing care movements is achieved by swinging a mannequin or briefly pulling on clothing.
[0126] Category D: Unauthorized opening of the lock. The waistband locking mechanism 3 was pulled directly without using a dedicated unlocking tool.
[0127] Category E: Tearing the side wings without opening the latches. This involves tearing the edge of the diaper's side wings without opening the latches.
[0128] Category F: The base of the lumbar support tape was forcibly torn off. The base area of the lumbar support tape was torn off without using a dedicated unlocking tool.
[0129] Each type of event was tested 30 times, for a total of 180 tests. The judgment criteria are as follows: Type A events outputting an installation error message are considered correct; Type B events not triggering an unauthorized uninstallation warning are considered correct; Type C events being filtered and not triggering an unauthorized uninstallation warning are considered correct; Type D, E, and F events triggering corresponding warnings and identifying the corresponding error type are considered correct.
[0130] The test results are shown in Table 1.
[0131] Table 1 Test Results of Example 1
[0132]
[0133] As shown in Table 1, under the test conditions of this embodiment, the system can identify the component connection status before entering monitoring, and distinguish between normal care unlocking, short-term force fluctuations, and unauthorized detachment behavior after the two components are reliably connected. For side wing tearing and waist patch root tearing that bypasses the latch, the control module 24 can determine the tearing area based on the regional state change of the partition tearing sensing unit 4 and send corresponding warning information.
[0134] 3.2 Example 2: Parameter calling based on magnetic induction authorization and consumable identification
[0135] The difference between this embodiment and Embodiment 1 is that the authorization triggering unit 21 uses magnetic induction, and a magnetic component is installed in the dedicated unlocking tool; the consumable identification unit 14 uses interface port encoding to distinguish between adult medium and adult large replaceable disposable absorbent components 1. The control module 24 calls the corresponding threshold according to the read port encoding.
[0136] The adult medium-sized disposable absorbent component has a preset pull threshold of 10N, and the adult large-sized disposable absorbent component has a preset pull threshold of 14N; both have an authorization unlock time window of 8 seconds and a preset duration of 1.2 seconds.
[0137] The test events included normal care unlocking, simulated positional changes, unauthorized pulling of the buckle, lateral tearing, and tearing at the base of the lumbar patch. Each event was tested 20 times, for a total of 100 tests. The test results are shown in Table 2.
[0138] Table 2 Test Results of Example 2
[0139]
[0140] This embodiment illustrates that the authorization trigger signal is not limited to electrical connection. Magnetic induction can still be used to generate the authorization unlock time window and time sequence matching. When the consumable identification unit 14 is used to identify different types of disposable absorbent components, the control module 24 can call the corresponding parameters to adapt to different waist sizes and product models.
[0141] IV. Comparative Example
[0142] 4.1 Comparative Example 1: Two-part scheme without component connection status confirmation
[0143] The difference between this comparative example and Example 1 is that the control module 24 does not detect the connection status between the reusable detection component 2 and the replaceable disposable absorption component 1 before entering the early warning monitoring, nor does it read the initial state of the partition tear sensing unit 4. Instead, it directly enters the authorization recognition, force detection and abnormal judgment process after detecting that the waist locking structure 3 is closed.
[0144] Three types of installation anomalies were set up during the test: the first type was that the detection interface 27 and the consumable interface area 13 were not fully crimped; the second type was that the consumable interface area 13 had local contamination or increased contact resistance; the third type was that the replaceable disposable absorption component 1 had local breakage of its partition tear sensing unit 4 before installation. Each type of anomaly was tested 20 times, for a total of 60 times. If the system could prompt the installation anomaly before entering the formal unauthorized removal judgment, it was judged as correct handling; if the system misjudged the installation anomaly as a tearing anomaly during use, or failed to identify subsequent tearing events due to unreliable interface connection, it was judged as a false alarm or missed alarm.
[0145] The test results are shown in Table 3.
[0146] Table 3 shows the test results of Comparative Example 1.
[0147]
[0148] As shown in Table 3, without confirming the component connection status and reading the initial status, improperly connected interfaces, abnormal contact impedance, or initial damage to the disposable absorption component in the two-part structure can easily be mistaken by the subsequent warning process as tearing behavior during use, or result in unreliable reading of the partition tearing status signal. In contrast, Example 1 confirms the connection status, consumable identification information, and the initial status of the partition tearing sensing unit 4 before entering formal monitoring, which can alert to abnormalities during the installation stage and reduce the possibility of mixing installation abnormalities into the unauthorized removal judgment process.
[0149] 4.2 Comparative Example 2: Two-part scheme without partition tear sensing unit
[0150] This comparative example also adopts a two-part structure of reusable detection component 2 and replaceable disposable absorption component 1.
[0151] The difference between this comparative example and Example 1 is that the replaceable disposable absorbent assembly 1 does not have a partition tear sensing unit 4, nor does it have a corresponding waistband locking area detection partition 41, waistband base area detection partition 42, and diaper side wing edge area detection partition 43. The control module 24 only determines normal care unlocking and unauthorized removal based on authorized trigger signals, buckle status change signals, buckle opening signals, and waistband tension signals.
[0152] The test events included four categories: normal care unlocking, unauthorized pulling of the waistband locking structure, tearing the side edges of the diaper while bypassing the waistband locking structure, and tearing the base area of the waistband tape. Each category was tested 30 times, for a total of 120 tests. Normal care unlocking did not trigger an alarm, unauthorized pulling of the locking structure triggered an alarm, and side wing tearing and waistband tape tearing were identified as unauthorized removal actions and judged as correct. If side wing tearing or waistband tape tearing was not identified, or if abnormal areas were not output, it was judged as a missed detection or insufficient identification. The test results are shown in Table 4.
[0153] Table 4. Test results of Comparative Example 2
[0154]
[0155] As shown in Table 4, without the partition tear sensing unit 4, the system mainly relies on the buckle status and waistband tension for judgment. For actions involving directly pulling open the waistband locking structure 3, this scheme can still identify the issue to some extent through changes in the buckle status; however, for situations where the diaper's side wing edge or waistband tape is torn away from the waistband locking structure 3, if the tearing process does not cause significant buckle displacement, or if the waistband tension change is insufficient to continuously exceed the threshold, false alarms are likely to occur. Furthermore, this scheme cannot determine whether the tearing occurs in the waistband locking area, the waistband tape base area, or the diaper side wing edge area; the nursing terminal still needs to manually confirm the abnormal location after receiving the warning.
[0156] In contrast, in Embodiment 1, a partitioned tear sensing unit 4 is provided on the replaceable disposable absorbent assembly 1, and the waistband locking area detection partition 41, the waistband root area detection partition 42, and the diaper side wing edge area detection partition 43 correspond to different access ports, identification resistance values, or area codes, respectively. When any detection partition is disconnected, experiences a sudden change in resistance, changes in conduction status, or has an abnormal area code, the control module 24 can determine the tearing area based on the changed detection partition, and generate a corresponding warning level by combining the authorized trigger signal, the buckle status change signal, and the waistband tension signal.
[0157] As can be seen from the comprehensive embodiments and comparative examples, this implementation divides the adult diaper into a reusable detection component 2 and a replaceable disposable absorbent component 1. This allows the control module 24, communication module 25, power module 26, authorization trigger unit 21, waistband force detection unit 22, and buckle status detection unit 23 to be reused with the reusable detection component 2, while the diaper body 11, absorbent core 12, and low-cost partition tear sensing unit 4 are replaced with the replaceable disposable absorbent component 1. Therefore, it avoids the disposal of electronic components such as the control module, communication module, and power module with each diaper change, reducing the redundant configuration of high-value electronic components in disposable consumables.
[0158] In the early warning control process, this embodiment first detects the connection status between the reusable detection component 2 and the replaceable disposable absorbent component 1, and reads the consumable identification information and the initial state of the partition tear sensing unit 4. When the detection interface 27 is not properly connected to the consumable interface area 13, the contact impedance is abnormal, or the initial state of the partition tear sensing unit 4 is abnormal, the control module 24 first outputs an installation abnormality prompt and suspends the judgment of unauthorized removal behavior. This process can distinguish between installation stage abnormalities and tearing abnormalities during use, reducing false alarms and missed alarms caused by unreliable interface connections or initial damage to consumables.
[0159] During normal monitoring, the control module 24 generates an authorized unlocking time window after detecting an authorized trigger signal, and performs timing matching on the authorized trigger signal, the buckle status change signal, and the buckle opening signal. Only when all three satisfy a preset sequence and fall within the authorized unlocking time window is it considered a normal care unlock. If no authorized trigger signal is detected, the buckle opening signal precedes the authorized trigger signal, or the three do not satisfy the preset sequence, the control module 24 further determines whether unauthorized removal behavior exists based on the waist tension peak, tension duration, buckle displacement, and the state changes of the partition tearing sensing unit 4. This allows for the differentiation between normal diaper changing operations performed by caregivers using dedicated unlocking tools and the user's actions of pulling, bending, or tearing the diaper.
[0160] Furthermore, the zoned tear sensing unit 4 covers the waistband locking area, the base of the waistband tab, and the edge of the diaper side wings. For actions that bypass the waistband locking structure 3 and directly tear the base of the waistband tab or the edge of the side wings, even if the change in the locking state is not obvious, the control module 24 can still identify the tearing area based on the disconnection, sudden change in resistance, change in conduction state, or abnormal area coding of the corresponding detection zone. Combined with short-term force fluctuation filtering rules, this embodiment can also distinguish between short-term waistband tension peaks caused by turning over, sitting up, nursing movement, or occasional pulling and unauthorized removal behavior, thereby reducing unnecessary nursing reminders.
[0161] Therefore, this embodiment can realize connection confirmation, authorization identification, timing matching, unauthorized removal judgment, partition tearing identification, and graded warning output in a two-part adult diaper structure, and is suitable for scenarios such as home care, nursing home care, and incontinence care in wards.
