Description

Technical Field

[0001] The present invention relates to the technical field of emergency equipment, and in particular to a cab rapid conversion emergency isolation and transportation system. Background Art

[0002] In the public health emergency and infectious disease prevention and control system, safe and efficient pathogen and case transport equipment is the core link to block the transmission chain. Although traditional ambulances can achieve basic isolation functions, their specialized design leads to high purchase costs and insufficient regional configuration density, making it difficult to cope with large-scale epidemic outbreaks or emergency needs in remote areas.

[0003] At present, the research and development of vehicle-mounted isolation devices is polarized. First, professional medical vehicles mostly adopt a fixed negative pressure cabin design, which has a high isolation level and can effectively block the spread of the virus. However, the modification cycle is long, and a lot of time and manpower costs are required. The purchase cost is high, and it is difficult to put it into use quickly in an emergency. In addition, the fixed negative pressure cabin occupies a large space in the vehicle, and the space utilization rate is low. When the vehicle is not transporting patients, the cabin space is idle and wasted seriously. Second, some simple isolation devices are mostly built with temporary enclosures made of PVC tarpaulins, which have a short deployment time and can be quickly built and put into use. However, its air tightness is poor, it cannot effectively prevent the escape of the virus, and the isolation effect is not good. More importantly, this type of simple device lacks intelligent control design, cannot monitor the environmental parameters and patient conditions in the isolation space in real time, has a high risk of cross infection, and is difficult to meet the stringent requirements of infectious disease prevention and control. In addition, this type of defect is particularly prominent in rural medical emergency response scenarios, because its own medical resources are limited, lack of professional isolation and transportation equipment, and simple temporary isolation facilities cannot guarantee transportation safety, which greatly affects the effective use of grassroots emergency management capabilities.

When the failure rate exceeds the corresponding threshold, generate a daily maintenance suggestion and store it in the daily inspection report.

[0043] The working principle and advantages of the present invention are as follows:

[0044] The emergency isolation transfer system with rapid cab conversion of the present invention has carried out modular transformation and integration using a double-row pickup truck. As a general transportation tool with a保有量 of over 20 million vehicles, the double-row pickup truck has the characteristics of strong mobility and excellent chassis bearing capacity, but has not been effectively integrated into the emergency medical equipment system for a long time. Based on this, this solution has developed a rapid conversion isolation system based on the double-row pickup truck, which can realize the function conversion between daily use and emergency isolation through modular transformation, enabling ordinary transportation tools to be transformed into professional isolation transfer equipment in a short time, and effectively solving problems such as uneven allocation of emergency supplies and lag in professional vehicle scheduling. This technology has significant practical value for improving the grass-roots emergency management ability, the emergency response ability of rural medical institutions, and reducing the cost of public health event disposal. The key points are as follows:

[0045] First, the modular isolation cabin design of this solution realizes the rapid functional conversion of double-row pickup trucks through a detachable assembly structure. The isolation plate is fixed through the fixing grooves on the inner side wall, top surface and bottom surface of the vehicle, so that the rear space of an ordinary pickup truck can be transformed into an independent isolation unit that meets the infectious disease prevention and control standards in a short time. Compared with the traditional negative pressure ambulance model that relies on the chassis modification of special vehicles, this solution makes full use of the pickup truck resources with a stock of more than 20 million vehicles, solving the pain point of insufficient equipment configuration in primary medical institutions. In addition, the application of this solution can enable vehicles to meet daily transportation needs and quickly convert into professional isolation and transportation equipment in public health emergencies, realizing the maximization of equipment utilization of "peace and war". Simulation tests show that the deployment efficiency of this modular system is more than 3 times higher than that of traditional mobile cabins, and is particularly suitable for emergency rescue scenarios in areas with inconvenient transportation such as mountainous areas and rural areas.

[0046] Second, the air purification system set up in this scheme can create negative pressure conditions for the isolation space, and realize air purification and renewal, which can build an isolation protection barrier while ensuring the breathing comfort of the isolated personnel. Secondly, the medical rescue system realizes the coordinated operation of equipment through parameter coupling control strategy, and dynamically adjusts the system parameters based on the real-time physiological state of the isolated personnel and the real-time environmental conditions in the isolation space. It can coordinately optimize the physical sensation of the isolated personnel while maintaining the isolation environment to meet the standards (such as meeting the medical negative pressure isolation environment standards) to ensure their riding comfort.

[0047] Third, the information linkage system set up in this plan can access regional medical resource data in real time, and by building a reception capacity evaluation model and dynamically calculating the weight index of each medical institution using the entropy method, it can objectively analyze multiple parameters such as the number of negative pressure wards and the rate of medical staff on duty, and objectively quantify the treatment capacity of each medical institution. Furthermore, combined with factors such as treatment capacity, time cost, and cost, medical institutions suitable for isolated personnel can be screened, which can quickly complete targeted and practical reference-valued transfer decisions, which will help optimize the matching of medical resources and improve transfer efficiency.

[0048] Fourth, the maintenance system set up in this scheme can intelligently complete the daily inspection and management of vehicles. Among them, by setting up the airtightness attenuation model, the initial leakage rate, aging coefficient and random disturbance parameters are comprehensively considered, and the airtightness status of the isolation space can be accurately and real-time monitored. Whether it is the slow aging of the vehicle in daily use or the airtightness abnormality caused by emergencies, it can be detected in time to effectively prevent the virus from spreading through air leakage and ensure the stability and reliability of the isolation effect. Secondly, by collecting historical operation data of the air purification system and medical rescue system, and using the LSTM model to predict the system failure rate, potential problems of the equipment can be discovered in advance. Once the failure rate exceeds the threshold, daily maintenance recommendations are immediately generated and stored in the inspection report, which can realize intelligent monitoring and preventive maintenance of the system operation, ensure the stable operation of the system during the transportation process, and help improve the reliability and safety of the entire emergency isolation and transportation system.

In this embodiment, the negative pressure detector can be installed on the inner wall of the vehicle in the rear space.

[0061] The medical rescue system is used to construct a medical environment, including a medical equipment group arranged in the rear space.

[0063] The isolation management system is used to monitor the operating status of the medical rescue system and the air purification system, as well as the physiological status of the isolated personnel in the rear space, and intelligently adjust the operating parameters of the medical rescue system and the air purification system.

[0064] When the isolation management system intelligently regulates the operating parameters of the medical rescue system and the air purification system, it regulates them according to a multi-parameter coupling regulation strategy; the multi-parameter coupling regulation strategy includes:

[0065] Construct isolation space parameter model: X(t) = [P(t), T(t), O(t), C(t)] T ;

[0066] Among them, P(t) is the pressure difference between the isolation space and the outside world, in Pa; T(t) is the temperature in the isolation space (obtained by installing a temperature sensor in the isolation space), in °C; O(t) is the blood oxygen saturation of the isolated person, in %; C(t) is the PM2.5 concentration in the isolation space (obtained by installing a gas sensor in the isolation space), in μg / m 3 ;

[0067] Set the control objective function:

[0068] Where, X ref =[-15, 22, 95, 10] T is the target state, where -15 is the target P(t) value, 22 is the target T(t) value, 95 is the target O(t) value, and 10 is the target C(t) value;

[0069] Q and R are both weight matrices, and Q = diag(0.5, 0.3, 1.0, 0.2), R = diag(0.1, 0.2);

[0071] Use rolling horizon to optimize and control input values:

[0072]

[0073] And set the constraints as:

[0074] Through the above settings, the system integrates four key parameters, namely pressure difference, temperature, blood oxygen and PM2.5 concentration, and constructs a four-dimensional control space. Compared with traditional single-variable PID control, the rolling time domain optimization mechanism of MPC can predict future disturbances (such as sudden changes in pressure difference caused by the opening of the car door) within a period of every 10 seconds, and adjust the fresh air volume and oxygen flow rate in advance, reduce pressure difference fluctuations, and adaptively adjust the fresh air volume and oxygen flow rate when the physiological conditions of the isolated personnel fluctuate, which helps to improve the breathing comfort of the isolated personnel.

[0075] The information linkage system is used to exchange information with medical institutions, collect and analyze the reception intervals of medical institutions, screen out medical institutions suitable for isolated persons, and provide corresponding selection suggestions to vehicle drivers.

[0076] When the information linkage system collects and analyzes the reception intervals of medical institutions and selects medical institutions suitable for quarantined persons, the following steps are included:

[0077] Set the objective function: max[w 1 ·S j -w 2 ·D j +w 3 ·(1-C j / C max )];

[0080] Among them, D max is the maximum acceptable transit time; S min It is the minimum threshold of rescue capacity;

[0081] Set up the admission interval scoring model:

[0082] Among them, λ i is the indicator weight determined by entropy method; x ij is the original value of the i-th indicator of hospital j; x i,min and x i,max are the minimum and maximum values ​​of the ith indicator in all hospitals respectively; the indicator items include: number of negative pressure wards, remaining beds, number of P3 laboratories, number of infectious disease specialists, number of infectious disease specialist nurses, on-the-job rate of medical staff, and current remaining capacity.

[0083] Through the above settings, the formula system constructed by this system can achieve intelligent upgrades of medical resource matching and path planning through data-driven decision-making and dynamic balance of multiple objectives.

[0084] The maintenance system is used to detect the isolation effect when the isolation space is set up and there is no one in the isolation space; and to detect the operation of the system in the rear space and generate a daily inspection report.

[0085] When the maintenance system detects the isolation effect, it is detected based on the differential pressure decay method, including the following steps:

[0086] Set the airtightness decay model: Q(t) = Q 0 ·e -λt +∈(t);

[0087] Among them, Q 0 is the initial leakage rate, with the unit of m 3 / h, obtained by actual measurement and calibration; λ is the aging coefficient; ∈(t) is the random disturbance parameter, ∈(t)~N(0,0.02);

[0088] When Q(t)>0.3, generate an emergency airtight maintenance notice and push the notice to the vehicle driver;

[0089] When 0.1<Q(t)≤0.3, generate a daily airtight maintenance notice and store it in the daily inspection report;

[0090] When Q(t)≤0.1, generate an airtight maintenance normal notice and store it in the daily inspection report.

[0091] When the maintenance system detects the operation of the system in the rear space, it includes the following steps:

[0092] Collect the historical operation data of the air purification system and the medical rescue system, and use the LSTM model to predict the system failure rate. When the failure rate exceeds the corresponding threshold, generate a daily maintenance suggestion and store it in the daily inspection report.

[0093] The isolation management system, the information linkage system and the maintenance system can be integrated into the center console of the double-row pickup truck. Preferably, they can be linked with each device in the modular isolation cabin, the air purification system and the medical rescue system through a data acquisition module to collect their operation parameters, etc., for the isolation management system, the information linkage system and the maintenance system to call.

[0094] The interactive system is used for the interaction between the rear and front spaces of a double-row pickup truck, including a dual camera module and a secondary intercom located in the rear space, and a high-definition camera and a main intercom located in the front space; the dual camera module includes a main camera module installed on the inner wall of the vehicle in the rear space and a secondary camera module installed on the top surface of the rear space; the secondary camera module uses a fisheye lens. Specifically, the secondary intercom is installed in the rear space near the window; the main intercom is installed in a position that is easy for the driver to operate, and in this embodiment, it is installed above the center console. Optionally, the main intercom and the secondary intercom can be replaced with two-way intercoms, which are arranged on the isolation plate 1.

[0095] The interactive system enables effective interaction between the rear and front seats of the vehicle. By integrating advanced camera and intercom equipment, passengers in the front and back seats can communicate visually and verbally in real time, improving communication efficiency and riding experience.

[0096] The present embodiment provides a cab rapid conversion emergency isolation and transfer system, which can realize the functional conversion between daily use and emergency isolation through modular transformation, so that ordinary transportation tools can be transformed into professional isolation and transfer equipment in a short time, and can effectively solve the problems of unbalanced allocation of emergency materials and delayed dispatch of professional vehicles. This solution has significant practical value in improving the emergency management capabilities at the grassroots level, the emergency response capabilities of rural medical institutions, and reducing the cost of handling public health incidents.

[0097] Embodiment 2

[0098] A cab rapid conversion emergency isolation and transportation system is provided, based on the first embodiment, with the following improvements.

[0099] When monitoring the physiological state of the isolated personnel in the back row, the isolation management system also calculates the abnormal index of the isolated personnel to provide timely warning of the abnormal physiological state of the isolated personnel:

[0100] Abnormal Index

[0101] Among them, μ HR The median of the normal range of resting heart rate for adults (60-100 bpm) is 75 bpm; HR is the standard deviation of the resting heart rate of adults, which is set to 12; HR(t) is the resting heart rate of the isolated person, which can be collected from the electrocardiograph of the medical equipment group; It is the high probability distribution area of ​​blood oxygen saturation in healthy people, and the value is 97%; is the standard deviation of blood oxygen saturation in healthy people, and its value is 2; S p O 2(t) is the blood oxygen saturation of the quarantined person, which can be obtained from the pulse oximeter (or blood oxygen clip) of the medical equipment group. α and β are weight coefficients. In this embodiment, they are respectively set to 0.6 and 0.4.

[0102] When A(t) > 3.0, a first-level warning is triggered. The joint information linkage system pushes an emergency reception notice to the nearest medical institution, sends a driving suggestion to the vehicle driver to go to the nearest medical institution, and the on-vehicle medical staff conducts emergency treatment.

[0103] When 2.0 < A(t) ≤ 3.0, a second-level warning is triggered, reminding the on-vehicle medical staff to observe the patient's status through the camera and ask about subjective symptoms for emergency treatment.

[0104] When 1.5 < A(t) ≤ 2.0, a third-level warning is triggered, increasing the environmental monitoring frequency (the vital sign sampling period changes from 60s to 10s).

[0105] A rapid cab conversion emergency isolation transfer system provided by this embodiment can effectively monitor and timely control the status of quarantined persons. By setting three-level warning thresholds, a scientific emergency response gradient is established, which can avoid excessive medical responses and ensure timely handling of high-risk situations; it helps to improve the medical safety guarantee level during the transfer process and realizes the optimal allocation of limited resources.

[0106] Embodiment III

[0107] A rapid cab conversion emergency isolation transfer system has the following improvements based on Embodiment I.

[0108] When the information linkage system collects and analyzes the reception intervals of medical institutions and screens out medical institutions suitable for quarantined persons, D in the objective function set j is the time cost, and the value of the time cost is preferably obtained based on the path planning algorithm (i.e., corresponding to h(n)).

[0109] The path planning algorithm is: h(n) = α·h distance +β·h traffic +γ·h crowd ;

[0110] Among them, h traffic is the real-time road traffic speed retrieved based on a map software (such as Amap API); h distance is the traffic distance from the vehicle's location to the selected medical institution retrieved based on the map software; h crowd is the population density on the traffic road from the vehicle's location to the selected medical institution retrieved based on the map software. α, β, and γ are weight coefficients, which are respectively set to 0.5, 0.3, and 0.2 in this embodiment.

[0111] The cab rapid conversion emergency isolation and transportation system provided in this embodiment fully considers multi-dimensional factors when measuring time costs, and can accurately measure the time costs of going to different medical institutions and make the best route planning. Moreover, in the consideration of multi-dimensional factors, the crowd density index is particularly considered, and relatively avoiding crowded sections is more suitable for emergency isolation and transportation scenarios.
