Description

Technical Field

[0001] The present disclosure relates to the field of medical management technology, and in particular to an anti-lost positioning communication warning system for hospitalized patients, a warning method, and electronic equipment. Background Art

[0002] As my country's population ages, cognitive impairment is on the rise. This condition not only severely impacts patients' daily lives but also places a heavy burden on their families and society. Due to impaired memory, judgment, and orientation, patients frequently wander off, posing a safety hazard.

[0003] Therefore, once an inpatient goes missing, it puts enormous pressure on the patient's family and medical staff. Currently, when an inpatient goes missing, hospitals mostly take emergency measures after the fact (such as calling the police to find the patient), but they are unable to take effective preventive measures in advance.

[0004] Although there are existing positioning devices for patients who are lost, for example, publication number CN216853989U provides an anti-lost wristband for special groups, including a mounting box and a GPS positioning system. A Bluetooth locator is provided inside the mounting box, and the Bluetooth locator is connected to the guardian's mobile phone signal through the GPS positioning system. Rotation grooves are provided on both sides of the mounting box, and the inner walls of the two rotation grooves are respectively connected to a first arc-shaped positioning plate and a second arc-shaped positioning plate by a torsion spring. A fixing belt is fixedly installed on the outer surface of the first arc-shaped positioning plate. This anti-lost wristband for special groups, by providing a mounting box, a Bluetooth locator and an identification plate, enables the lost patient to contact the guardian through passers-by by calling the number on the identification plate. On the other hand, the guardian can use his or her mobile phone and connect the Bluetooth locator through the GPS positioning system to locate the lost patient, making it easier to find the lost patient. However, this method mainly relies on GPS positioning, which can only see the patient's location, but cannot set and monitor the alarm range in advance based on the patient's cognitive dysfunction. In other words, it cannot allow the patient to move within his or her acceptable range, and does not take the patient's cognitive ability into consideration for monitoring. Therefore, its positioning alarm monitoring has limitations. Summary of the Invention

[0005] In order to solve the above problems, the present application proposes an anti-lost positioning communication warning system, warning method and electronic equipment for hospitalized patients.

[0019] According to M, R, E, R max From the inside to the outside, it is divided into several movable rings.

[0020] Furthermore, the boundary crossing warning conditions include:

[0021] Set the out-of-bounds signal attenuation model:

[0030] When the patient exceeds the first inner activity ring, a first-level warning is triggered;

[0031] The same applies to the rest.

[0032] Furthermore, the X σ Based on historical boundary crossing event data, its value is optimized through machine learning algorithms.

[0033] Furthermore, the system includes:

[0040] The medical end is used to read the patient's final Bluetooth location for location tracking when receiving the early warning forwarded by the hospital management platform.

[0053] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0054] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0055] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0056] Example 1

[0057] The mobile wearable device in this application is one of the following devices:

[0058] Bracelet, wristband or mobile terminal.

[0059] This application is preferably a wristband. The wristband can refer to existing Bluetooth positioning wristbands and their applications. However, its positioning warning refers to the following technical solutions:

[0060] like Figure 1 As shown, in one aspect, the present application proposes a hospitalized patient anti-lost positioning communication warning system, the system comprising:

[0061] A mobile wearable device 1, on which a Bluetooth module is integrated;

[0062] Bluetooth positioning base station, used to receive Bluetooth signals transmitted by the Bluetooth module and obtain the corresponding real-time signal strength RSSI real , Bluetooth signal and its real-time signal strength RSSI real Synchronize to the hospital management platform;

[0063] Hospital management platform, used to combine patients’ individual information and set their activity range max And configure the corresponding out-of-bounds warning conditions, when the real-time signal strength RSSI real If the boundary crossing warning conditions are met, the warning will be triggered;

[0064] The mobile wearable device communicates with the hospital management platform via Bluetooth through a Bluetooth positioning base station.

[0065] When using the wristband to carry out anti-lost positioning and early warning for hospitalized patients, the present invention integrates the individual information of the patient and sets the activity range R max And configure the corresponding out-of-bounds warning conditions, when the real-time signal strength RSSI real If the crossing warning conditions are met, the warning will be triggered. Therefore, it is no longer necessary to rely solely on the independently set electronic fence to locate, monitor and warn patients. Instead, the patient's individual information such as age, medical history, dementia score, etc. is considered to set the activity range R max Therefore, patients can carry out activities within their cognitive range, breaking the rigid fence regulations brought by traditional Bluetooth positioning and making its use more flexible.

[0066] Generally, after a wristband is removed by a patient, especially one with dementia, it will continue to be powered. This is not conducive to the hospital's electricity use and will cause damage to electronic equipment. The wristband will need to be frequently collected and charged or the battery replaced. (Generally, the Bluetooth location before power failure will be recorded by the platform, so we do not need to consider the position of the wristband after power failure. It is assumed that the patient puts the wristband down after removing it.) To solve the power consumption problem, we have also designed the following applications:

[0067] like Figure 2 As shown, the wristband integrates an MCU, an electromagnetic locking assembly, a power supply, and a Bluetooth module. The electromagnetic locking assembly includes a magnetic end 2 and an adsorption end. The positive power supply 3 and the negative power supply of the Bluetooth module are respectively arranged on the magnetic end 2 and the adsorption end. When the magnetic end 2 and the adsorption end are magnetically connected, the MCU activates the Bluetooth module. When the magnetic end 2 and the adsorption end are separated, the MCU disconnects the Bluetooth module. The wristband is magnetically connected via the electromagnetic locking assembly. When the relatively set magnetic end 2 and the adsorption end are attracted together, the wristband is closed. At this time, the positive power supply 3 and the negative power supply (relatively set) of the Bluetooth module are in contact and energized, and the MCU activates the Bluetooth module; otherwise, the power is disconnected and the Bluetooth module is disconnected. This way of wearing a wristband is simpler than wearing a traditional watchband, and it can manage power consumption, avoid continuous power consumption, and save the cost of charging or replacing batteries.

[0068] When it is implemented:

[0069] 1. Wearing a mobile wearable device (smart bracelet)

[0070] 1. Bluetooth module:

[0071] It uses low-power Bluetooth 5.1 chips (such as Nordic nRF52840) and supports AoA / AoD (angle of arrival / angle of departure) positioning technology, with positioning accuracy improved to ±1 meter.

[0072] Anti-disassembly detection can be integrated: the wearing status is double-verified through the optical heart rate sensor + accelerometer. If abnormal disassembly is detected (such as no skin contact signal for 30 seconds), the SOS alarm will be triggered immediately.

[0073] Individualized information collection:

[0074] The built-in NFC module automatically associates the medical record tags in the HIS system (such as dementia score, fall risk level) after scanning the patient's wristband ID, and dynamically adjusts the activity range threshold.

[0075] 2. Bluetooth positioning base station

[0076] Deployment strategy:

[0077] Base stations are deployed at key nodes such as ward corridors and ward entrances, with a density of one every 10 meters and an installation height of ≥2.5 meters (to avoid interference from human obstruction).

[0078] The base station supports frequency hopping multiple channels (FHSS) technology to automatically avoid Wi-Fi band conflicts (2.4GHz band interference).

[0079] Signal synchronization mechanism:

[0080] The base station uploads RSSI (signal strength) data to the hospital management platform in real time via Wi-Fi or LoRaWAN, with a transmission delay of ≤500ms.

[0081] 2. Dynamics of Individualized Activity Scope

[0082] Combined with the patient's individual information, set the activity range R max And configure the corresponding crossing warning conditions. The individualized electronic fence rule engine is designed as follows:

[0083] Furthermore, the R max The configuration is as follows:

[0084]

[0085] P base The default coverage radius of the Bluetooth positioning base station;

[0086] M is the patient's mobility score, which ranges from 0.5 to 1.5 and is dynamically calculated by the physician based on age and medical history;

[0087] R is the risk level coefficient 0.1-0.9, calculated based on the patient's dementia severity score;

[0088] E is the environmental interference factor, 1.0-2.0, which is adjusted according to the building structure and crowd density;

[0089] According to M, R, E, R maxFrom the inside to the outside, it is divided into several movable rings.

[0090] R max The setting is based on the patient's M, R, and E, and no longer relies solely on the default coverage radius of the Bluetooth positioning base station. Therefore, the patient's activity range can be set in combination with the patient's hospitalization status and environment, and the activity limit can be set considering their cognitive ability. In addition, this department can set R according to the assessed M, R, and E. max From the inside to the outside, it is divided into several activity rings, such as Figure 3 As shown, the patient initially moves within the Level I activity ring. When they enter the Level I activity ring's warning boundary, an alarm is triggered. The platform sends a Level I warning to the patient's administrator's handheld PDA terminal, simultaneously displaying their location. A Level III warning indicates that the patient has left the monitoring range and is about to be lost.

[0091] This office also sets the optimization conditions for boundary crossing warning:

[0092] Furthermore, the boundary crossing warning conditions include:

[0093] Set the out-of-bounds signal attenuation model:

[0094] RSSI threshold =P0-10nlg(R max / d0)+X σ ,

[0095] RSSI threshold The preset Bluetooth signal strength threshold unit is dBm, which corresponds to the critical value of the signal strength at the boundary of the patient's activity range;

[0096] P0 is the Bluetooth module in R max The reference distance d0 within the range is usually the signal strength calibration value at 1 meter. The unit is dBm and is determined by on-site calibration.

[0097] n is the empirical value of the path loss exponent, reflecting the signal attenuation rate. The default value is 2.0-4.0 for indoor and 0.3-1.0 for outdoor.

[0098] X σ The unit of the environmental noise correction factor is dBm, which is used to compensate for multipath interference and is usually between -5 and 5 dBm. σ Based on historical boundary crossing event data, the value is optimized through machine learning algorithms;

[0099] Set the boundary crossing warning conditions when:

[0100] RSSI real ≤RSSI threshold ,

[0101] Determining that the patient exceeds the preset range of activity triggers an alert, including:

[0102] When the patient exceeds the first inner activity ring, a first-level warning is triggered;

[0103] The same applies to the rest.

[0104] This department adopts the cross-border signal attenuation model to measure the RSSI of the patient's Bluetooth signal in real-time tracking. real To make a judgment, in order to carry out the attenuation positioning warning of Bluetooth signal, this department carries out multi-level dynamic warning, combines the path loss index and the environmental noise correction factor to make the judgment of the out-of-bounds warning.

[0105] For each level of warning, the corresponding level of warning can be triggered according to the activity ring that crosses the boundary. Combined with the above cross-border warning conditions, the hierarchical warning mechanism can be refined, for example:

[0106] Level 1 warning (mild crossing of the border):

[0107] Condition: RSSI real ≤RSSI threshold and lasts ≤3 minutes;

[0108] Action: The bracelet vibrates and the LED flashes. The platform records the event but does not notify medical staff.

[0109] Level 2 warning (serious crossing of the border):

[0110] Conditions: Continuous crossing of the boundary for more than 3 minutes or a single crossing of the boundary distance exceeds 1.5R max ;

[0111] Action: Push the alarm to the nurse station screen and start camera linkage tracking (retrieve the ward surveillance video).

[0112] Anti-interference strategy dynamic calibration:

[0113] Base station signal calibration is automatically performed every morning: the baseline P0 value in the empty ward is measured and the path loss index n is updated (based on the average of the previous 7 days).

[0114] Furthermore, the system includes:

[0115] The medical end is used to read the patient's final Bluetooth location in the first activity ring for location tracking upon receiving the first-level warning forwarded by the hospital management platform; and the rest are similar;

[0116] The medical terminal is in communication connection with the hospital management platform.

[0117] The platform manages the medical devices (PDAs or EDAs) responsible for each patient. When a patient triggers an alert, it sends a corresponding level of alert notification to the medical staff responsible for that patient. It also sends Bluetooth location and out-of-bounds information, allowing medical staff to monitor the patient's location and out-of-bounds status in a timely manner.
