Description

Technical Field

[0001] This invention relates to the field of medical emergency equipment and intelligent navigation technology, specifically to a vehicle-mounted intelligent positioning device for stroke emergency map and a system for ensuring timely access to medical care. Background Technology

[0002] Stroke (commonly known as apoplexy) is an acute cerebrovascular disease with rapid onset, rapid progression, and extremely high rates of disability and mortality. Clinical studies have shown that for every minute of delay in acute ischemic stroke, 1.9 million brain cells die; and for every 15 minutes of reduction in DNT (time from admission to thrombolysis), the patient's survival rate increases by 4%. Therefore, the core of stroke emergency care lies in "racing against time." The shorter the time from the onset of the disease to receiving effective treatment, the better the patient's prognosis.

[0003] Currently, stroke emergency care mainly relies on traditional emergency models, which have several drawbacks: First, the positioning accuracy is insufficient. Existing vehicle positioning systems mostly rely on conventional GPS navigation, which is easily affected by building obstructions and signal interference, making it impossible to accurately obtain the patient's real-time location and difficult to quickly connect to nearby medical institutions qualified to treat stroke. Second, the matching of emergency resources is lagging behind. Medical staff or family members need to manually search for nearby hospitals, making it difficult to quickly screen for stroke centers qualified to perform thrombolysis and thrombectomy, and also difficult to obtain information such as the hospital's real-time capacity and bed availability, which can easily lead to "going to distant hospitals instead of nearby ones" or "sending patients to the wrong hospitals." The situation of "being hospitalized" delays the opportunity for treatment; third, the timeliness of the entire medical process cannot be controlled. From the patient's onset of illness and call for emergency help, ambulance dispatch, and transport to the hospital's preparation for admission, there is a lack of effective linkage between each link. It is impossible to monitor the time spent in each link in real time, and it is also difficult to trigger the hospital's preparation process in advance, resulting in the superposition of pre-hospital delays and in-hospital delays; fourth, most of the existing emergency systems are designed for fixed scenarios, and there are few integrated devices adapted to vehicle-mounted mobile scenarios. There is a lack of seamless connection between positioning, maps, emergency data and hospital systems, which makes it difficult to meet the needs of dynamic positioning and real-time decision-making in vehicle-mounted emergency rescue.

[0004] While some stroke emergency maps and positioning systems exist, such as the stroke emergency thrombolysis map released by the Hangzhou Emergency Medical Center, which provides information on hospitals qualified for thrombolysis and thrombectomy, these systems largely rely on fixed terminals or mobile applications. They are ill-suited for dynamic vehicle-mounted scenarios and lack integration with vehicle-mounted emergency equipment. This prevents integrated management of positioning, triage, and transport, and the absence of a comprehensive time-efficiency control mechanism, hindering efforts to minimize treatment time. Therefore, developing an intelligent device and system that is adaptable to vehicle-mounted scenarios, offers accurate positioning, efficient resource matching, and ensures timely medical care throughout the entire process is crucial for addressing the current pain points in stroke emergency care. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted intelligent positioning device for stroke emergency map and a system for ensuring timely medical treatment, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The vehicle-mounted stroke emergency map intelligent positioning device includes a positioning module, a map module, a data transmission module, a control module, a display and interaction module, an emergency assistance module, and a power supply module, all installed in an emergency vehicle, and all modules work together. The positioning module adopts multi-source fusion positioning technology, including a GPS positioning unit, a Beidou positioning unit, and an auxiliary positioning unit; The map module has a built-in electronic map for stroke emergency care, pre-stores information on all medical institutions in the area that are qualified to treat stroke, updates road conditions, emergency lane distribution and AED device locations in real time, supports dynamic planning and real-time adjustment of emergency routes, and can simultaneously display the real-time location of vehicles and patients as well as the distribution of emergency resources within a 30-kilometer radius. The control module is the core of the device. It adopts an embedded processor and integrates a data processing unit, a logic decision-making unit, and a timeliness monitoring unit. The data processing unit performs noise reduction, integration, and analysis on various types of data. The power supply module adopts a dual power supply mode of vehicle power supply and backup power supply. The backup power supply is a high-capacity lithium battery with a capacity of ≥10000mAh, which can provide continuous power supply for ≥4 hours when the vehicle loses power.

[0007] A further improvement of the technical solution of the present invention is that the data transmission module adopts 5G+4G dual-mode communication technology and integrates Bluetooth and WiFi modules, which can realize data interaction with vehicle-mounted emergency equipment, medical staff handheld terminals and hospital reception systems, and realize the transmission of location data and patient vital sign data, as well as the reception of instructions and reception information.

[0008] A further improvement of the technical solution of the present invention is that: the display interaction module adopts a high-definition touch screen, which is installed in the cockpit and the medical cabin, and supports split-screen display. The cockpit display screen displays navigation, road conditions, positioning and warning information, while the medical cabin display screen displays patient vital signs, emergency map, hospital information and timely data; the display interaction module integrates a voice broadcast unit, which can broadcast positioning results, route guidance, hospital information and timely warnings in real time.

[0009] A further improvement of the technical solution of the present invention is that the emergency assistance module includes a vital signs collection unit, a condition assessment unit, and an emergency record unit. The vital signs collection unit is connected to the vehicle-mounted emergency equipment to collect data such as the patient's heart rate, blood pressure, blood oxygen saturation, and electrocardiogram. The condition assessment unit has built-in G-FAST and RACE scoring algorithms, which can quickly complete the assessment of the patient's condition level and stroke type. The emergency record unit automatically records the data of the entire emergency process to form an emergency record.

[0010] A further improvement to the technical solution of the present invention is that the medical institution information pre-stored in the map module includes hospital level, treatment capacity, real-time bed status, emergency equipment configuration, attending physician resources, hospital contact information and precise coordinates.

[0011] This invention also proposes a vehicle-mounted stroke emergency map intelligent positioning and medical treatment timeliness guarantee system based on the above-described device, comprising the following steps: Step 1: Device startup and positioning initialization. After the emergency vehicle starts, the positioning device starts automatically. The positioning module completes the positioning initialization and obtains the real-time location and driving status of the vehicle. The control module performs noise reduction processing on the positioning data, and the map module loads the emergency-specific map and updates the relevant data. Step 2: Patient information entry and condition assessment. Medical staff enter the patient's basic information through the display interaction module, collect the patient's vital signs data through the emergency assistance module, and use the condition assessment unit to complete the assessment of the condition level and stroke type. The assessment results are transmitted to the control module. Step 3: Intelligent positioning and emergency resource matching. The control module combines vehicle positioning data, patient assessment results and emergency resource data to accurately mark the patient's location, select suitable medical institutions and sort them according to the priority of transfer timeliness. Step 4: Dynamic route planning and transfer time management. The control module combines real-time traffic conditions to dynamically plan the optimal emergency route, monitors transfer time in real time, triggers an early warning if timeout occurs, and replans alternative routes. It also transmits relevant data to the remote dispatch center and the receiving hospital simultaneously. Step 5: Pre-hospital-in-hospital linkage and patient reception preparation. The control module transmits relevant patient information and estimated arrival time to the receiving hospital through the data transmission module, triggering the patient reception preparation process and enabling real-time communication between the on-board medical staff and the receiving hospital, as well as resource coordination with the remote dispatch center. Step 6: Confirmation of Admission and Timeliness Review. After the ambulance arrives, medical staff confirm the admission is completed. The control module records the admission time, the emergency assistance module organizes the emergency records and transmits them to the relevant database, and the device automatically updates the emergency resource data. Step 7: Device standby and maintenance. After the emergency treatment is completed, the device switches to standby mode, the vehicle power supply charges the backup power, medical staff perform routine checks on the device, and the map module automatically updates relevant data.

[0012] A further improvement of the technical solution of the present invention is that: in step 1, the positioning initialization response time is ≤10 seconds, and the map module synchronously updates real-time traffic conditions, distribution of emergency resources and AED device location; in step 3, the patient location marking error is ≤1 meter, and the screening range is medical institutions within a 30-kilometer radius that have the corresponding rescue capabilities.

[0013] A further improvement of the technical solution of the present invention is that: in step 4, the route planning time is ≤30 seconds, emergency channels and unobstructed road sections are prioritized, and congested, construction and traffic control sections are avoided; during the transfer process, the positioning module updates the timeliness data at least once every 30 minutes, and triggers voice and screen pop-up warnings simultaneously when there is an anomaly.

[0014] A further improvement of the technical solution of the present invention is that: in step 5, real-time voice and video communication between the vehicle-mounted medical staff and the receiving hospital is realized through 5G communication, and the remote dispatch center can coordinate with the transportation department to open green channels and coordinate with the hospital to increase the capacity to receive patients.

[0015] A further improvement of the technical solution of the present invention is that: in step 6, if an abnormality occurs in the timeliness of the emergency rescue process, the control module automatically generates an abnormality report and marks the cause of the abnormality; in step 7, the routine checks of medical staff include checks on the positioning module signal, data transmission status, and sensitivity of the emergency rescue assistance module.

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1 Vehicle-mounted stroke emergency map intelligent positioning device This embodiment provides a vehicle-mounted intelligent positioning device for stroke emergency map, which is installed in an emergency vehicle, and its specific structure is as follows: The positioning module uses GPS+BeiDou dual-mode positioning, combined with a MEMS inertial navigation module and base station-assisted positioning, achieving a positioning accuracy of 0.8 meters. When satellite signals are interrupted, the inertial navigation module can achieve 35 minutes of positioning compensation through gyroscopes and accelerometers to ensure positioning continuity. The map module has a built-in electronic map for regional stroke emergency care, pre-stored with information on 20 hospitals in the area qualified to treat stroke, including 3 primary stroke centers, 8 secondary stroke centers, and 9 community hospitals qualified to perform thrombolysis. It also updates road condition information and the location of 120 AED devices in real time. The data transmission module adopts a 5G dual-mode communication module (supporting SA / NSA modes) with a transmission rate of ≥1Gbps. It also integrates Bluetooth 5.2 and WiFi 6 modules, enabling data interaction with devices such as vehicle-mounted defibrillator monitors and blood gas analyzers, with a latency of ≤10ms. The control module uses an STM32H743 processor, integrating data processing, logical decision-making, and timeliness monitoring functions. It presets standard time consumption for each stage of stroke emergency care: positioning response ≤10 seconds, route planning ≤30 seconds, mild stroke transport ≤30 minutes, and severe stroke transport ≤20 minutes. The display and interaction module uses a 10.1-inch high-definition touchscreen, with one in the cockpit and one in the medical cabin, supporting split-screen display. The voice broadcast unit uses a high-definition speaker to broadcast navigation guidance and warning information in real time. The emergency assistance module includes a vital signs acquisition device and a stroke rapid assessment terminal, which can collect eight vital signs data such as heart rate, blood pressure, and blood oxygen. It has a built-in G-FAST scoring algorithm and can complete the condition assessment within 10 seconds. The power supply module uses the vehicle's 12V power supply and has a backup lithium battery with a capacity of 12,000mAh, which can provide continuous power for 5 hours.

[0023] Example 2 Vehicle-mounted stroke emergency map intelligent positioning and medical treatment time guarantee system Based on the device of Embodiment 1, this embodiment provides a vehicle-mounted intelligent positioning and medical treatment timeliness guarantee system for stroke emergency maps, the specific steps of which are as follows: Step 1: Device Start-up and Positioning Initialization: After the emergency vehicle starts, the positioning device automatically starts, and GPS, Beidou, inertial navigation and base station assisted positioning units work synchronously to complete positioning initialization within 10 seconds, obtain the real-time position of the vehicle, and the driving speed is 0km / h. The positioning data is transmitted to the control module and noise reduction is completed; the map module loads a special map for stroke emergency and updates real-time traffic conditions and emergency resource data synchronously.

[0024] Step 2: Patient information entry and condition assessment: After receiving an emergency call, medical staff enter the patient information, collect the patient's vital signs using a vital signs acquisition device, and perform G-FAST scoring based on the patient's symptoms through the condition assessment unit to determine if it is a severe ischemic stroke, suspected LVO.

[0025] Step 3: Intelligent Positioning and Emergency Resource Matching: The control module receives vehicle positioning data and patient assessment results, and combines them with emergency resource data from the map module to filter for Level 1 stroke centers with thrombectomy qualifications within a 30-kilometer radius. Two hospitals are selected and sorted by "transfer time + DNT": Hospital A (8 km away, estimated transfer time 15 minutes, estimated DNT 20 minutes) and Hospital B (10 km away, estimated transfer time 20 minutes, estimated DNT 18 minutes). The optimal hospital is Hospital A (minimum transfer time + DNT 35 minutes). The matching result is simultaneously displayed on the medical cabin screen.

[0026] Step 4: Dynamic Route Planning and Transfer Time Management: The control module plans the optimal route based on real-time traffic conditions, prioritizing emergency lanes and avoiding congested sections. Navigation guidance is simultaneously displayed on the cockpit screen, with a voice announcement stating, "Heading to Hospital A, 8 kilometers in total, estimated arrival time 15 minutes." During the transfer, the positioning module updates the vehicle's location every 5 seconds, and the control module monitors the transfer time in real time. When the vehicle reaches 3 kilometers and encounters temporary traffic control, the control module replans an alternative route within 10 seconds, increasing the estimated transfer time by 3 minutes and triggering a voice warning: "Route congested, alternative route adjusted, estimated arrival time 18 minutes, please speed up." At the same time, the warning information is transmitted to the remote dispatch center.

[0027] Step 5: Pre-hospital-in-hospital coordination and patient preparation: The control module transmits patient information, condition assessment results, vital sign data, and estimated arrival time to Hospital A via 5G communication, triggering the patient preparation process. Hospital A reserves a thrombectomy bed, prepares thrombectomy equipment and a receiving medical team. Medical staff guide the onboard medical personnel in pre-operative preparation through video communication. The remote dispatch center coordinates with the transportation department to open a green channel for the ambulance.

[0028] Step 6: Patient Reception Confirmation and Timeliness Review: The ambulance arrives at Hospital A 17 minutes later. Medical staff confirm the patient reception is complete. The control module records the reception time, and the emergency assistance module automatically organizes the emergency records, including location records, route information, patient condition data, transport time of 17 minutes, hospital reception information, etc., and transmits them to the remote dispatch center and Hospital A's database. The transport time did not exceed the standard severe stroke transport time of ≤20 minutes, and there was no timeliness abnormality. The device automatically updates the bed status of Hospital A to "occupied" and synchronizes it to the map module.

[0029] Step 7: Device Standby and Maintenance: After the emergency rescue is completed, the device switches to standby mode, the vehicle power supply charges the backup lithium battery, medical personnel check the status of each module of the device to ensure that the positioning signal and data transmission are normal, the map module automatically updates the road conditions and emergency resource data, and the device maintenance is completed.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
