[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] To solve the problem that in the prior art, when transporting patients, there is a lack of monitoring of data such as the patient's heart rate, blood pressure, body temperature, and blood oxygen saturation, and it is impossible to timely judge the change of the wounded's condition, affecting the treatment effect, please refer to Figures 1 - 10 , the following technical solutions are provided in this embodiment: Integrated intelligent transfer stretcher for full - process monitoring and auxiliary triage of critically injured patients, including a stretcher main body 3.

On the upper surface of the stretcher main body 3, there is a sponge layer 13. On one side of the stretcher main body 3, a monitoring host 5 is installed. Inside the monitoring host 5, there is a storage battery 14. On the monitoring host 5, there are control buttons and an alarm. When the monitoring host 5 detects abnormalities in the body temperature, blood pressure, heart rate, and blood oxygen of the patient, an alarm signal is sent through the alarm. Both the first fixing belt 10 and the second fixing belt 11 are elastic bands. On the upper surface of one side of the stretcher main body 3, there is a head baffle 6, which is used to fix the head of the patient to prevent the patient from moving during transportation due to jolts, thus avoiding aggravating the patient's injury. At both ends of the stretcher main body 3, there are handles. During use, by rotating the crank 26, the adjusting screw 24 rotates, driving two groups of first support rods 23 to move along the adjusting screw 24 to adjust the height of the stretcher main body 3. Place the patient on the stretcher main body 3, and use the first fixing belt 10 and the second fixing belt 11 to fix the patient to prevent the patient from moving during transportation, accidentally falling, or affecting the injury, thus affecting subsequent treatment. When the stretcher main body 3 needs to be used alone, separate the stretcher main body 3 from the mounting frame 1, and then the stretcher main body 3 can be used alone. The transportation of the patient can be completed in areas where it is not convenient to move. At the same time, by separating the stretcher main body 3 from the mounting frame 1, the weight of the stretcher main body 3 can be reduced during use, making it more labor - saving when in use; It also includes a mounting frame 1. Inside the mounting frame 1, there is a card slot 12, and the clamping block 9 is movably installed in the card slot 12. On one side of the mounting frame 1 close to the monitoring host 5, there is a storage box 4. Inside the storage box 4, a blood oxygen and heart rate monitor 7 and a blood pressure monitoring cuff 8 are stored. The blood oxygen and heart rate monitor 7 and the blood pressure monitoring cuff 8 are connected to the monitoring host 5 through wires. On the front and back sides of the mounting frame 1, there are second fixing belts 11. On one side of the mounting frame 1, there is a through - hole to facilitate the handle on the stretcher main body 3 to pass through. On the lower surface of the mounting frame 1, a support mechanism 2 is fixed.

[0021] The support mechanism 2 includes a top support frame 21, a moving wheel body 22, a first support rod 23, an adjusting screw rod 24, a second rotating rod 25, a crank 26, a bottom support frame 27 and a second support rod 28. The top support frame 21 and the bottom support frame 27 are connected by the first support rod 23 and the second support rod 28. The first support rod 23 and the second support rod 28 are arranged crosswise. The tops of the first support rod 23 and the second support rod 28 are connected by the second rotating rod 25. Two second rotating rods 25 are provided, which are respectively arranged on the left and right sides of the adjusting screw rod 24. The top of the first support rod 23 is movably installed on the top support frame 27. The adjusting screw rod 24 horizontally penetrates through the centers of the top support frame 21 and the second rotating rod 25 and is rotatably installed on the top support frame 21. The crank 26 is arranged at the left end of the adjusting screw rod 24. The lower surface of the bottom support frame 21 is provided with the moving wheel body 22. The moving wheel body 22 is provided with an anti-slip mechanism 29. When in use, rotate the crank 26 to drive the adjusting screw rod 24 to rotate. By the rotation of the adjusting screw rod 24, the two second rotating rods 25 on the left and right move in opposite directions, and then the first support rod 23 and the second support rod 28 move, and then the stretcher body 3 realizes lifting and lowering.

[0022] The moving wheel body 22 includes an anti-slip wheel 221, a ratchet wheel 223 and a rotating shaft 222. The outside of the anti-slip wheel 221 is fixed with the ratchet wheel 223. The anti-slip wheel 221 is rotatably installed on the rotating shaft 222.

One end of the movable rod 291 is fixed on the pawl 298. The movable rod 291 is sleeved in the fixed rod 292, and the movable rod 291 and the fixed rod 292 are connected by the spring 293. The bottom of the fixed rod 292 is installed on the support plate 294. The bottom of the support plate 294 is installed on the extending end of the hydraulic rod 295. One end of the hydraulic rod 295 away from the support plate 294 is installed on the fixing plate 296. The fixing plate 296 is fixed on the anti-slip wheel 221. When the anti-slip wheel 221 moves clockwise, the pawl 298 contracts inward under the action of the spring 293, so that the anti-slip wheel 221 can move normally. When there is a situation where the anti-slip wheel 221 regresses on an uphill section, at this time the pawl 298 catches the ratchet wheel 223, so that the anti-slip wheel 221 can stop in place, and there will be no situation where the anti-slip wheel 221 regresses on the uphill section, resulting in the overturning of the stretcher body 3. When it is not necessary to prevent the anti-slip wheel 221 from slipping, start the hydraulic rod 295 and pull the support plate 294 backward, so that the pawl 298 leaves the ratchet wheel 223.

[0024] The monitoring host 5 internally includes a CPU controller, a data storage module, a data analysis module, and a data transmission module. Among them, the CPU controller respectively controls the blood oxygen and heart rate monitor 7, the blood pressure detector 81, and the body temperature detector 82 one by one. The data storage module collects the data detected by the blood oxygen and heart rate monitor 7, the blood pressure detector 81, and the body temperature detector 82 and stores them. The data analysis module analyzes the data stored in the data storage module and transmits the analysis results to the in-hospital system and the medical staff's mobile APP through the data transmission module, facilitating the medical staff to view the wounded's situation during the transfer process. The data transmission module specifically includes: Collect detailed monitoring data and analysis reports related to warnings, including the time of occurrence of abnormalities, duration, abnormal values, and trends; Format the warning information and related data, and send the warning information and detailed reports to the in-hospital system and the medical staff's mobile APP through the data transmission module. The medical staff give corresponding treatment plans based on the detailed reports, can timely judge the changes in the wounded's condition, and ensure the treatment effect of the wounded; The medical staff record the time of receiving the warning information and the response time, and track the response situation of the warning information and the changes in the wounded's condition.

[0025] On the inner side of the blood pressure monitoring cuff 8, there are respectively a blood pressure detector 81 and a body temperature detector 82. On one end of the outer side of the blood pressure monitoring cuff 8, there is a male surface of Velcro. On the inner side of the blood pressure monitoring cuff 8, away from one male surface of Velcro, there is a female surface of Velcro. The blood pressure detector 81 detects the blood pressure data of the wounded, and the body temperature detector 82 detects the body temperature of the wounded and transmits the detected data to the monitoring host 5.

[0026] The data analysis module specifically includes: Extract the stored data from the data storage module and perform feature analysis, and extract the evaluation features of heart rate, blood pressure, body temperature, and blood oxygen saturation data from the results of the feature analysis; Set the standard value thresholds corresponding to each evaluation feature, and compare the extracted evaluation features with the corresponding standard value thresholds; According to the comparison results, identify the abnormal features exceeding the thresholds, and mark the identified abnormal features, including marking the types of abnormalities; Analyze the data marked as abnormal to obtain the abnormal fluctuation index and its abnormal trend of heart rate, blood pressure, body temperature, and blood oxygen saturation data; Set the warning thresholds for the abnormal fluctuation index and its abnormal trend. When the abnormal fluctuation index and its abnormal trend exceed the warning thresholds, generate warning information.

[0027] Analyze the data marked as abnormal, specifically including: Using stream processing technology, the real-time data stream is divided into continuous time windows, and each time window contains data within a time period of a fixed time length; Within each time window, the collected data is calculated and analyzed in real time to detect the change trend of the data; According to the real-time values and change trends of heart rate, blood pressure, body temperature, and blood oxygen saturation, statistical methods are used to calculate the abnormal fluctuation indexes of heart rate, blood pressure, body temperature, and blood oxygen saturation data; According to the abnormal fluctuation indexes, analyze the deviation degree of heart rate, blood pressure, body temperature, and blood oxygen saturation data from the normal range; According to the deviation degree, output the abnormal fluctuation indexes and abnormal trends of heart rate, blood pressure, body temperature, and blood oxygen saturation data.

[0028] Based on the data obtained by the data analysis module and combined with the data marked as abnormal, the following steps are used for analysis and calculation. The calculation steps include: Step 1: The CPU controller calculates the abnormal fluctuation index based on the data storage module, data analysis module, data transmission module, and formula (1): (1) Wherein, is the abnormal fluctuation index at time t, are the physiological parameter values collected in real time by the blood pressure detector 81, body temperature detector 82, and blood oxygen and heart rate monitor 7. t and t - k are time values, is the mean value of the clinical standard threshold (pre-stored in the database of the monitoring host 5 and called according to the age and gender of the wounded), is the preset clinical allowable fluctuation standard deviation, is the real-time weight coefficient input by the doctor during the initial triage and entered into the monitoring host 5, is the historical weight coefficient (pre-stored in the database of the monitoring host 5 and set and called according to the initial triage classification result), and T is the time window length; Step 2: The CPU controller calculates the abnormal trend warning index based on formula (2): (2) Wherein, is the abnormal trend warning index, is the adaptive adjustment coefficient, is the time index (each time window contains data within a time period of a fixed time length), is the abnormal fluctuation index at time Step 3: The CPU controller analyzes the abnormal fluctuation index and the abnormal trend warning index according to the preset warning decision logic. When or When any one exceeds the warning threshold, a warning message is generated, and first aid suggestions are pushed to the medical staff terminal through the data transmission module.

[0029] To facilitate an intuitive explanation of the above solution, it is elaborated through the following example: Suppose medical staff are using the intelligent transfer stretcher of the present invention to transfer a wounded person with a penetrating abdominal injury caused by a car accident: Transfer scenario background: Wounded person's condition: Systolic blood pressure continues to rise (from 120 mmHg to 160 mmHg) Device status: The blood pressure monitoring cuff 8 collects data every 30 seconds, and the monitoring host 5 analyzes it in real time Time window: Set T = 10 minutes (i.e., analyze the data trend in the most recent 10 minutes) In step one: Formula decomposition and clinical correspondence 1. Real-time anomaly detection Indicates that the current blood pressure is 40 mmHg higher than the standard value (μ = 120 mmHg), exceeding 2.67 times the standard deviation ( ) 2. Historical trend assessment Suppose the blood pressure values in the past 10 minutes are: 130, 135, 142, 148, 152, 155, 158, 160, 160, 160 (mmHg), then ; 3. Dynamic weight adjustment Initial moment When: , , 5 minutes later Seconds: , , mainly for acutely bleeding wounded persons, and more attention is paid to the continuous deterioration trend rather than the instantaneous value over time.

[0030] Therefore, when is greater than 2.5 (the preset threshold), the alarm of the monitoring host 5 is activated, and medical staff are required to timely judge the change in the wounded person's condition.

[0031] In step two: Formula decomposition and clinical correspondence 1. Suppose , it indicates that the patient's blood pressure is already at a dangerous level; 2. Suppose in the past Values: 1.1, 1.4, 1.8, 2.1, 2.5, 2.8, 3.0, 3.1, 3.2, 3.2, then , ; At this time, If it is greater than 2.5, it prompts the nurse to check the position of the blood pressure cuff, If it is greater than 0.8, the monitoring host 5 automatically pushes "Suspected internal bleeding, emergency CT examination is recommended".

[0032] The beneficial effects of the above solution are: 1. Real-time monitoring and accurate judgment By collecting physiological parameters such as blood pressure, body temperature, and blood oxygen in real time (such as ), and comparing them with the preset clinical standard thresholds and standard deviations , when the condition of the wounded appears abnormal, the abnormal fluctuation index and the abnormal trend warning index can be quickly calculated. This real-time data monitoring can help medical staff timely detect the fluctuations in the health status of the wounded and identify potential critical situations in advance.

[0033] 2. Intelligent warning mechanism In this solution, when the abnormal fluctuation index or the abnormal trend warning index exceeds the preset threshold, the monitoring host 5 will automatically generate a warning message and push it to the medical staff terminal. This intelligent warning system not only depends on instantaneous values, but also combines historical data for trend analysis, more accurately reflecting the real health changes of the wounded. For example, if the blood pressure change shows a continuous deteriorating trend, the weight coefficient will be automatically adjusted, so that the algorithm can pay more attention to the long-term trend rather than short-term instantaneous fluctuations, further enhancing the adaptability and accuracy of the warning system.

[0034] 3. Dynamic adjustment and personalized monitoring The system automatically adjusts the monitoring weight coefficient according to the injury deterioration factor of the patient and the initial vital signs of the wounded. This dynamic adjustment makes the system not only applicable to the situations of different wounded, but also able to flexibly adjust the warning mechanism according to different injury stages. For example, for patients with acute bleeding, the system will pay more attention to monitoring the deterioration trend over time, avoiding over-reliance on a single instantaneous abnormal value, thus better meeting the clinical needs.

[0035] 4. Assisting medical staff in making decisions When the health condition of the wounded reaches the warning threshold, the system not only provides immediate warnings but also gives specific suggestions (such as "suspected internal bleeding, it is recommended to have an emergency CT examination"). This significantly improves the efficiency and accuracy of medical decision-making, especially in high-pressure and emergency medical environments, saving a large amount of decision-making time for medical staff and improving the treatment efficiency.

[0036] 5. Improve the safety of wounded transfer The intelligent transfer stretcher system of this solution can continuously monitor the vital signs of the wounded during the transfer process, ensuring that during the transfer, any changes in the wounded's condition can be promptly detected and responded to, avoiding medical omissions caused by failure to timely identify the deterioration of the condition, and greatly enhancing the safety during the transfer process.

[0037] 6. Reduce human errors Traditional monitoring relies on medical staff to judge the changes in the condition based on experience, which is easily affected by human factors (such as fatigue, lack of experience, etc.). However, this solution can significantly reduce human errors by automatically analyzing data, evaluating trends, and issuing warnings through algorithms, and ensure that each wounded person can receive timely and accurate monitoring and response.

The guiding upright column 36 is fixedly arranged at the top of the mounting frame 1; A secondary annular clamp 19 is movably arranged inside the arc-shaped support bracket one 18. A blind hole is formed at the bottom of the inner wall of the avoidance groove 16, and the bottom of the rubber rod 19 is movably installed in the blind hole at the bottom of the inner wall of the avoidance groove 16. The top of the rubber rod 29 sequentially passes through the avoidance groove 16, the arc-shaped groove 17, and the arc-shaped support bracket one 18 and is fixedly connected with the secondary annular clamp 19; A main annular clamp 34 is arranged inside the arc-shaped support bracket two 32, and a plurality of groups of stabilizing springs two 33 are used to connect the arc-shaped support bracket two 32 and the main annular clamp 34. The same rubber anti-slip ridges two 35 and rubber anti-slip ridges one 20 are arranged on one side of the main annular clamp 34 and the secondary annular clamp 19 that are close to each other.

[0039] A mounting vertical frame 38 is fixedly arranged at the top of the mounting frame 1. A first connecting rod 40 is rotatably connected inside the mounting vertical frame 38. A handle 37 is fixedly arranged at the top of the first connecting rod 40. The bottom of the first connecting rod 40 is rotatably connected with the mounting frame 1. A spiral thread 39 is arranged around the outer wall of the first connecting rod 40; The outer wall of the second arc-shaped support bracket 32 extends towards the direction close to the first connecting rod 40 to form a guide member 41, and gear teeth 43 are formed at the end of the guide member 41. A through groove 42 for passing through the guide post 36 is formed on the guide member 41, and the gear teeth 43 are engaged with the spiral thread 39 on the outer wall of the first connecting rod 40; The bottom of the second arc-shaped support bracket 32 extends downward to form an insertion rod 45, and a return spring 44 is sleeved on the insertion rod 45. The insertion rod 45 movably penetrates through the first arc-shaped support bracket 18.

[0040] To prevent the stretcher main body 3 from shaking on the mounting frame 1 when carrying a patient, the handle on the stretcher main body 3 is passed through the through hole formed by the first arc-shaped support bracket 18 and the second arc-shaped support bracket 32. Due to the gravity of the stretcher main body 3, the auxiliary annular hoop 19 will push several groups of rubber rods 29 downward and compress the first stabilizing spring 31, thereby providing a certain reverse supporting force. Then, the handle 37 is rotated to drive the first connecting rod 40 to rotate. Since the guide member 41 formed by the extension of the outer wall of the second arc-shaped support bracket 32 is provided with gear teeth 43 engaged with the spiral thread 39, at this time, the second arc-shaped support bracket 32 will move downward along the guide post 36. Furthermore, when the insertion rod 45 is inserted into the first arc-shaped support bracket 18, the main annular hoop 34 coincides with the handle on the stretcher main body 3 until several groups of second stabilizing springs 33 and the return spring 44 are compressed to the limit (that is, the handle 37 cannot be rotated anymore). At this time, it means that the auxiliary annular hoop 19 and the main annular hoop 34 completely hold the handle on the stretcher main body 3, and the settings of several groups of first rubber anti-slip ribs 20 and second rubber anti-slip ribs 35 further enhance the friction between the auxiliary annular hoop 19 and the main annular hoop 34 and the handle on the stretcher main body 3, thereby preventing the stretcher main body 3 from shaking on the mounting frame 1 when carrying a patient or the stretcher main body 3 slipping off the mounting frame 1 in case of an accident.

[0041] Working principle: When using the integrated intelligent transfer stretcher for full-course monitoring and auxiliary triage of critically injured patients of the present invention, according to Figures 1 - 7 , it includes the following steps: S1: Rotate the crank 26 to make the adjusting screw 24 rotate, drive the two first support rods 23 to move along the adjusting screw 24 to adjust the height of the stretcher main body 3, and stop after adjusting to the required height; S2: Place the wounded on the stretcher main body 3 and fix the wounded with the first fixing belt 10 and the second fixing belt 11; S3: Wear the blood oxygen and heart rate monitor 7 and the blood pressure monitoring cuff 8 on the fingers and arms of the wounded respectively, collect and monitor the heart rate, blood pressure, body temperature and blood oxygen saturation of the wounded, and transmit the collected and monitored data to the monitoring host 5; S4: The monitoring host 5 receives the collected and monitored data for storage, analyzes the stored data, and issues early warnings for abnormal results; S5: Transmit the analysis results to the in-hospital system and the mobile APP of medical staff. The medical staff record the time when the early warning information is sent and the response time, and track the response of the early warning information and the changes in the condition of the wounded.

[0042] In summary, for the integrated intelligent transfer stretcher for full-course monitoring and auxiliary triage of critically injured patients of the present invention, the wounded is placed on the stretcher main body 3, and the first fixing belt 10 and the second fixing belt 11 are used to fix the wounded, and the stretcher stabilizing assembly 15 is used to fix the stretcher main body 3 to prevent the wounded from moving, accidentally falling or affecting the injury condition during the transfer process, thereby affecting subsequent treatment. When the stretcher main body 3 needs to be used alone, the stretcher main body 3 is separated from the mounting frame 1, and the stretcher main body 3 can be used alone. The transfer of the wounded can be completed in areas where it is not convenient to move. At the same time, by separating the stretcher main body 3 from the mounting frame 1, the weight of the stretcher main body 3 can be reduced during use, making it more labor-saving. Through the anti-slip mechanism 29 provided, when the anti-slip wheel 221 shows a backward situation on an uphill section, the pawl 298 can catch the ratchet wheel 223, so that the anti-slip wheel 221 can stop in place, and the situation where the anti-slip wheel 221 rolls backward on the uphill section and causes the stretcher main body 3 to overturn will not occur, ensuring the anti-slip effect of the stretcher main body 3 and making it safer and more reliable during the transfer of the wounded. By monitoring and analyzing the condition of the wounded during the transfer process and transmitting the monitored data to the in-hospital system and the mobile APP of medical staff, medical staff can timely understand the injury condition of the wounded and judge the changes in the condition of the wounded, and give corresponding treatment plans, ensuring the treatment effect of the wounded.
