Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a precise anesthesia assisting device for emergency treatment of pre-hospital craniocerebral trauma. Background Art

[0002] In pre-hospital emergency care, the treatment of patients with craniocerebral trauma is particularly critical, and anesthesia management is directly related to the patient's life safety and subsequent treatment effects. Traditional emergency anesthesia methods for craniocerebral trauma often rely on the experience and judgment of medical staff, and determine the dosage of anesthetics by manually assessing the patient's height and weight. This method has many shortcomings.

[0003] First, the accuracy of manual assessment of patients' height and weight is limited. In actual operation, due to factors such as time pressure and complex environment, it is difficult for medical staff to accurately measure the height and weight of patients in a short period of time, which often leads to errors in the estimation of the amount of anesthetic drugs used.

[0004] Secondly, traditional anesthesia assistive devices usually require additional equipment or steps to obtain patient height and weight information, which not only increases the complexity of operation, but also reduces the portability and emergency response speed of the device. In emergency rescue and pre-hospital treatment scenarios, these deficiencies may directly affect the treatment effect of patients.

[0005] Finally, traditional anesthesia-assisted devices lack intelligent management and data analysis functions. In the medical field, data collection and analysis are crucial to improving treatment effects and medical quality. However, traditional anesthesia-assisted devices are often unable to perform intelligent analysis and processing of monitoring data, resulting in a large amount of valuable data resources being wasted.

[0006] In summary, the traditional emergency anesthesia method for craniocerebral trauma has many shortcomings in terms of accuracy, real-time monitoring, portability, emergency response speed, intelligent management and data analysis. Therefore, there is an urgent need for a precise anesthesia auxiliary device that can overcome these shortcomings to improve the treatment effect and medical quality of craniocerebral trauma patients. Summary of the invention

[0007] To solve the above problems, the present invention provides a precise anesthesia assisting device for emergency treatment of pre-hospital craniocerebral trauma, which is used to realize automatic measurement of patient height and weight information, precise calculation and adaptive adjustment of anesthetic dosage, and intelligent management and analysis of data through integrated monitoring components and intelligent controller design, thereby improving the overall performance and practicality of the device and providing strong guarantee for patient safety and medical quality.

[0008] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a precise anesthesia auxiliary device for emergency treatment of pre-hospital craniocerebral trauma, comprising a treatment bed, on which a fixed module, an anesthetic drug storage module for storing anesthetic agents and a drug delivery module are installed, the fixed module comprising a shell, the shell is installed on the top of the treatment bed, a protective layer is installed on the top of the shell, a plurality of installation slots are opened in the shell, and monitoring components are installed in the installation slots, the monitoring components comprising a pressure sensor, the pressure sensor is fixedly installed to the bottom of the installation slot, a spring is installed on the side wall of the installation slot, a support rod is provided on the spring sleeve, one end of the spring is fixedly connected to the side wall of the installation slot, and the other end of the spring is fixedly connected to the support rod, the pressure sensor signal is connected to a controller, and the controller is used to receive preset position information and pressure threshold of the pressure sensor;

[0009] When the controller receives the real-time pressure data monitored by the pressure sensor, the controller compares the initial pressure data of the pressure sensor with the real-time pressure data, and determines the patient's height information based on the comparison result and the preset position information of the pressure sensor;

[0010] At the same time, the controller determines the patient's weight information based on the comparison results of the real-time pressure data and the pressure threshold;

[0011] The controller calculates the actual amount of anesthetic agent required by the patient based on the obtained height information and weight information of the patient, and sends a drug administration instruction to the drug administration module based on the amount of anesthetic agent.

[0012] The technical principle of the above scheme is as follows: the fixed module is composed of a shell, a protective layer and an installation slot, which provides a stable installation environment for the monitoring component. The pressure sensor in the monitoring component can sensitively capture the pressure changes generated when the patient lies on the treatment bed through the design of springs and support rods. When the patient lies on the treatment bed, the distribution of his weight will cause the pressure on the pressure sensor to change. The controller can calculate the patient's height by comparing the real-time pressure data with the preset initial pressure data (representing the no-load state) and combining the position information of the pressure sensor (that is, the position of the installation slot). At the same time, the patient's weight can be estimated by comparing the real-time pressure data with the preset pressure threshold.

[0013] Based on the patient's height and weight information, the controller uses a preset algorithm to calculate the actual amount of anesthetic drugs required by the patient. This calculation process takes into account the correlation between the dose of anesthetic drugs and the patient's weight and height, ensuring the accuracy and safety of anesthesia. Based on the calculation results, the controller sends precise dosing instructions to the dosing module to achieve automatic and quantitative dosing of anesthetic drugs.

[0014] The above scheme has the following beneficial effects:

[0015] 1. Compared with the prior art method of manually assessing the patient's height and weight to determine the dosage of anesthetic agents, this solution realizes automatic and accurate measurement of the patient's height and weight information through the pressure sensor and spring support structure integrated in the mounting slot, combined with the intelligent analysis of the controller. This not only improves the accuracy and efficiency of the measurement, but also reduces human errors, ensures the accurate calculation of the dosage of anesthetic agents, and thus improves the safety and effect of anesthesia.

[0016] 2. Compared with the traditional anesthesia assisting device which lacks real-time monitoring and adaptive adjustment functions, this solution can dynamically adjust the dosage of anesthetic agents according to the actual condition of the patient through the analysis of real-time pressure data by the controller. This adaptive capability enables the device to respond in time when the patient's condition changes, ensuring the stability of the anesthesia process and the safety of the patient.

[0017] 3. Compared with the traditional method that requires additional equipment or steps to obtain the patient's height and weight information, this solution directly integrates the monitoring component into the fixed module of the treatment bed, simplifies the operation process, and improves the integration and portability of the overall device. This not only facilitates the operation of medical staff, but also makes the device more suitable for emergency rescue and pre-hospital treatment scenarios, improving the speed and efficiency of emergency response.

[0018] 4. Compared with traditional anesthesia auxiliary devices that lack intelligent management and data analysis, this solution not only achieves accurate calculation of anesthetic dosage through intelligent analysis and processing of monitoring data by the controller, but also provides valuable data support for subsequent medical analysis and research. This intelligent feature not only improves the functionality and practicality of the device, but also provides a powerful tool for data analysis and decision-making in the medical field.

[0019] Furthermore, the drug administration module includes a metering pump and an infusion pipeline. The input end of the metering pump is connected to the anesthetic drug storage module, the output end of the metering pump is connected to the infusion pipeline, the metering pump is connected to the controller signal, and the metering pump is used to control the drug administration speed and dosage of the anesthetic agent according to the drug administration instructions of the controller.

[0020] Beneficial effects: The metering pump can accurately adjust the speed and amount of anesthetic drug administration according to the controller's administration instructions. This precise control ensures the stability and controllability of the anesthesia process, avoids the risk of too deep or too shallow anesthesia due to improper administration, and thus improves the safety of anesthesia and the comfort of the patient. Through the signal connection with the controller, the metering pump can automatically execute the administration instructions without manual adjustment by medical staff. This reduces human intervention and operation steps, reduces the difficulty of operation and the error rate, and also improves work efficiency. Since the metering pump can be flexibly adjusted according to the instructions of the controller, the drug administration module can adapt to the weight, height and anesthesia needs of different patients. This adaptability makes the device more flexible and reliable in dealing with different situations.

[0021] Furthermore, a flow sensor and a check valve are provided on the infusion pipeline. The flow sensor is used to monitor the real-time drug administration speed, and the check valve is used to prevent the anesthetic from flowing back during the drug administration process. The flow sensor is connected to the controller signal. The controller compares the real-time drug administration speed monitored by the flow sensor with the drug administration speed of the metering pump. If the comparison result is inconsistent, it is determined that the drug administration speed deviates from the preset value, and the controller adjusts the working state of the metering pump.

[0022] Beneficial effects: The setting of the flow sensor enables the controller to monitor the actual drug delivery speed in real time and compare it with the preset drug delivery speed of the metering pump. Once a deviation is found, the controller can quickly adjust the working state of the metering pump to ensure the stability and accuracy of the drug delivery speed. This real-time monitoring and adjustment mechanism greatly improves the controllability and safety of the anesthesia process. The addition of the check valve effectively prevents the backflow of anesthetic agents during the drug delivery process. This avoids drug waste, contamination, and possible patient discomfort or risks caused by backflow. The presence of the check valve ensures the unidirectional flow of anesthetic agents, further improving the safety and reliability of the drug delivery process. By comparing the real-time drug delivery speed monitored by the flow sensor and the drug delivery speed of the metering pump, the controller can promptly detect and handle abnormal conditions in the drug delivery system. This mechanism enhances the robustness and fault detection capabilities of the system, making the device more flexible and reliable in dealing with emergencies. Accurate drug delivery speed and measures to prevent backflow jointly optimize the patient's anesthesia experience and reduce the discomfort and complications that may be caused by improper drug delivery.

[0023] Furthermore, a temperature monitoring component is provided in the anesthetic drug storage module, and the temperature monitoring component includes a temperature sensor. The temperature sensor is used to monitor the storage temperature of the anesthetic agent in real time. The temperature sensor is connected to the controller signal. When the real-time temperature data monitored by the temperature sensor is not within the temperature threshold preset in the controller, the controller sends an alarm signal.

[0024] Beneficial effects: Real-time monitoring of the storage temperature of anesthetic agents through temperature sensors can ensure that the storage environment of anesthetic drugs is always in the best state, which helps to detect temperature abnormalities in time, so as to take corresponding measures to adjust and avoid the drug from becoming ineffective or deteriorating due to improper temperature. The temperature monitoring component can ensure that the drug is stored within the appropriate temperature range, thereby minimizing the risk of drug degradation or failure due to temperature fluctuations and improving the safety of drug use. At the same time, it can also avoid the loss or waste of drugs due to improper storage and reduce medical costs.

[0025] Furthermore, it also includes an early warning component, which includes an indicator light and a buzzer. The indicator light is used to emit different light signals, and the buzzer is used to emit different sound signals. Both the indicator light and the buzzer are connected to the controller signal. When the controller detects that any one of the real-time pressure data, real-time drug delivery speed and real-time temperature data is abnormal, the controller instructs the early warning component to send an alarm signal.

[0026] Beneficial effects: Through the two alarm modes of indicator light and buzzer, the attention of the operator can be quickly attracted when the controller detects any abnormality in the real-time pressure data, real-time drug delivery speed or real-time temperature data. This multiple alarm mechanism can ensure that abnormal situations are discovered in time, improve the response speed, and help to take measures to solve the problem quickly and prevent the situation from deteriorating. The indicator light can emit light signals of different colors, while the buzzer can emit sound signals of different tones or rhythms. These intuitive and easy-to-understand alarm signals enable operators to quickly identify the type and severity of the abnormality, so as to take targeted countermeasures and improve processing efficiency.

[0027] Furthermore, the treatment bed includes a bed board, the top of the bed board is fixedly connected to the bottom of the shell, a movable component is installed at the bottom of the bed board, the movable component includes a foldable bracket, the top of the foldable bracket is fixedly connected to the bottom of the bed board, and a roller with a braking function is installed at the bottom of the foldable bracket, and the roller is a universal wheel structure.

[0028] Beneficial effects: The foldable bracket installed at the bottom of the bed board combined with the universal roller with brake function allows the treatment bed to be easily moved in the ward, operating room or other medical facilities. This design greatly reduces the physical burden of medical staff in moving patients. The structure of the universal roller allows the treatment bed to turn flexibly and adapt to various complex medical environments, such as narrow corridors and corners. The brake device on the roller can quickly fix the bed when needed to prevent the treatment bed from moving uncontrollably, thereby ensuring the safety of the patient.

[0029] Furthermore, a display screen and an operation panel are installed on one side of the bed board. The display screen is used to display patient information, anesthetic dosage, drug administration speed and alarm signals after being processed by the controller, and the operation panel is used for medical staff to manually input patient information or adjust thresholds.

[0030] Beneficial effects: The display screen can display the patient information, anesthetic dosage, drug delivery speed and alarm signals processed by the controller in real time, providing medical staff with a clear and intuitive data view. This instant feedback mechanism helps medical staff quickly understand the patient's status and key parameters of the anesthesia process, so as to make accurate judgments and decisions. The operation panel allows medical staff to manually input patient information or adjust thresholds, which simplifies the operation process and improves work efficiency. Medical staff can flexibly adjust anesthesia parameters according to actual needs to ensure the personalization and accuracy of the anesthesia process. The integrated design of the display screen and the operation panel makes the treatment bed more modern and intelligent, and improves the overall quality of the medical environment.

[0031] Furthermore, a life monitoring module is installed on the treatment bed, which is used to monitor the patient's real-time vital signs data. The life monitoring module includes a body temperature sensor, a heart rate monitor, a blood pressure monitor and a blood oxygen saturation monitor. The body temperature sensor, the heart rate monitor, the blood pressure monitor and the blood oxygen saturation monitor are all connected to the controller signal. The controller adjusts the dosage and administration speed of the anesthetic agent according to the real-time vital signs data.

[0032] Beneficial effects: The life monitoring module can monitor the patient's vital signs data such as body temperature, heart rate, blood pressure and blood oxygen saturation in real time, providing medical staff with instant and accurate patient status information. The controller automatically adjusts the dosage and administration speed of anesthetic agents based on these real-time data to ensure the accuracy and safety of the anesthesia process. By monitoring the patient's vital signs in real time, medical staff can promptly detect and deal with potential anesthesia risks, such as hypotension, arrhythmia, etc., thereby avoiding or reducing the occurrence of anesthesia complications. Automatically adjusting the dosage and administration speed of anesthetic agents helps maintain the stability of the patient's vital signs during anesthesia and improves the safety of anesthesia.

[0033] Furthermore, it also includes a wireless communication module, which is connected to the controller signal and is used to transmit the patient's vital signs data, anesthetic dosage, drug administration speed and alarm signals to the remote medical center in real time.

[0034] Beneficial effects: Through the wireless communication module, doctors can remotely monitor the patient's condition, reducing the time and workload of on-site inspections. At the same time, the transmission of real-time data also helps doctors make decisions faster and improve the efficiency of medical services. Through the wireless communication module, doctors can allocate medical resources more flexibly. For example, when there are a large number of patients or their conditions are serious, doctors can give priority to emergency situations to ensure the rational allocation and utilization of medical resources.

[0035] Furthermore, an auxiliary component is installed on the bed board, which includes a number of support frames and limb restraint belts, which are fixedly connected to both sides of the bed board, and the limb restraint belts are used to restrain the patient's limbs; it also includes a vomit collection component, which is detachably connected to one side of the bed board.

[0036] Beneficial effects: The design of the support frame provides additional support for the patient, especially during surgery or treatment, to ensure the patient's stable position and prevent accidental injuries caused by movement or turning over. The use of limb restraints can effectively restrain the patient's limbs and prevent them from making excessive actions in an unconscious or anesthetized state, such as scratching wounds, pulling out catheters, etc., thereby protecting the patient from injury. The vomit collection component can quickly and effectively collect the patient's vomit and prevent it from splashing onto the bed or the ground, thereby keeping the treatment environment clean and hygienic. The convenience and practicality of the vomit collection component can reduce the embarrassment and discomfort of patients when vomiting, and improve their comfort and satisfaction during treatment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The following is further described in detail through specific implementation methods:

[0048] Embodiment 1:

[0049] As attached Figures 1 to 5 As shown: A precision anesthesia auxiliary device for emergency treatment of pre-hospital craniocerebral trauma, including a treatment bed, the treatment bed includes a bed board 1, a moving component is installed at the bottom of the bed board 1, and the moving component includes a foldable bracket 2. The foldable bracket 2 not only firmly supports the bed board 1, but also facilitates folding and storage when not in use to save space. The top of the foldable bracket 2 is fixedly connected to the bottom of the bed board 1, and a roller 3 with a braking function is installed at the bottom of the foldable bracket 2. The roller 3 is a universal wheel structure. The design of the universal wheel roller 3 enables the treatment bed to be easily moved on various terrains, and the braking function ensures the stability of the treatment bed when needed to prevent accidental sliding.

[0050] The bed board 1 of the treatment bed is equipped with a fixed module, an anesthetic drug storage module 9 for storing anesthetic drugs, and a drug delivery module, characterized in that the fixed module includes a shell 4, the top of the bed board 1 is fixedly connected to the bottom of the shell 4, and a protective layer 5 is installed on the top of the shell 4. In this embodiment, the protective layer 5 is composed of a gel pad. The protective layer 5 (gel pad) can effectively relieve the discomfort caused by the patient lying for a long time, and at the same time has a certain heat preservation effect, thereby improving the patient's comfort. A number of mounting slots 6 are provided in the shell 4, and monitoring components are installed in the mounting slots 6. The monitoring components include a pressure sensor, which is fixedly installed at the bottom of the mounting slot 6. The pressure sensor can accurately sense the pressure changes generated when the patient lies down. A spring 7 is installed on the side wall of the mounting slot 6, and the spring 7 is sleeved with a support rod 8. One end of the spring 7 is fixedly connected to the side wall of the mounting slot 6, and the other end of the spring 7 is fixedly connected to the support rod 8. The pressure sensor signal is connected to a controller, and the controller is used to preset the position information and pressure threshold of the pressure sensor. All pressure sensors form a grid, which can sense the pressure distribution at different positions.

[0051] When the controller receives real-time pressure data monitored by the pressure sensor, the controller compares the initial pressure data and the real-time pressure data of the pressure sensor, and determines the patient's height information based on the comparison result combined with the preset position information; at the same time, the controller sensor determines the patient's weight information based on the comparison result of the real-time pressure data and the pressure threshold; the controller calculates the actual amount of anesthetic required by the patient based on the obtained patient's height and weight information, and sends a drug administration instruction to the drug administration module based on the calculation result.

[0052] The drug delivery module includes a metering pump and an infusion pipeline. The input end of the metering pump is connected to the anesthetic drug storage module 9, the output end of the metering pump is connected to the infusion pipeline, and the metering pump is connected to the controller signal. The metering pump is used to control the drug delivery speed and dosage of the anesthetic agent according to the drug delivery instruction of the controller. A flow sensor and a check valve are provided on the infusion pipeline. The flow sensor is used to monitor the real-time drug delivery speed. The check valve is used to prevent the anesthetic agent from flowing back during the drug delivery process. The flow sensor is connected to the controller signal. The controller compares the real-time drug delivery speed monitored by the flow sensor with the drug delivery speed of the metering pump. If the comparison result is inconsistent, it means that the drug delivery speed deviates from the preset value, and the controller adjusts the working state of the metering pump.

[0053] A temperature monitoring component is provided in the anesthetic storage module 9, and the temperature monitoring component includes a temperature sensor, which is used to monitor the storage temperature of the anesthetic agent in real time to ensure that the anesthetic agent is stored within a suitable temperature range to avoid damage to the efficacy. The temperature sensor is connected to the controller signal, and when the real-time temperature data monitored by the temperature sensor is different from the temperature threshold in the controller, the controller will send an alarm signal.

[0054] A life monitoring module 11 is also installed on the treatment bed. The life monitoring module 11 is used to monitor the patient's real-time vital signs data in real time. The life monitoring module 11 includes a body temperature sensor, a heart rate monitor, a blood pressure monitor and a blood oxygen saturation monitor. The body temperature sensor, the heart rate monitor, the blood pressure monitor and the blood oxygen saturation monitor are all connected to the controller signal. The controller adjusts the dosage and administration speed of the anesthetic agent according to the real-time vital signs data.

[0055] A display screen 10 and an operation panel are installed on one side of the bed board 1. The display screen 10 is used to display patient information, anesthetic dosage, drug administration speed and alarm signals processed by the controller, and the operation panel is used for medical staff to manually input patient information or adjust thresholds.

[0056] The specific implementation process is as follows: Choose a safe and stable location to place the treatment bed, and ensure that there is enough space around for medical staff to operate. Place the patient on the treatment bed steadily, ensuring that the patient's body is in full contact with the gel pad. The soft material and thermal insulation effect of the gel pad can improve the patient's comfort and reduce the discomfort caused by lying for a long time. Manually enter the patient's basic information, such as name, age, and gender, through the operation panel so that the controller can perform subsequent data processing and analysis.

[0057] When the patient lies on the shell 4, the patient's own weight will produce downward pressure on the support rod 8, and this pressure will be transmitted to the pressure sensor at the bottom of the mounting groove 6. The pressure sensor can accurately sense this pressure change and convert it into an electrical signal for real-time monitoring. Since the pressure positions applied to the support rod 8 by different parts of the body will be different after patients of different heights lie down, the pressure sensor can capture these position differences. The controller receives real-time data from the pressure sensor and analyzes the spatial distribution of these data. In particular, it will look for the most edge position where the pressure change occurs. These edge positions usually correspond to the contact boundary between the patient's body and the shell 4, such as the edge of the head, foot or side. By identifying these edge positions and combining the preset shell 4 size and sensor layout, the controller can calculate the patient's height. For example, if the most edge position of the pressure change is located at one end of the sensor array, then the distance from this end to the other end (assuming that it represents the full length of the shell 4) minus a certain safety margin (considering that the patient may be fully stretched or the buffer area at the edge of the shell 4) can roughly estimate the patient's height.

[0058] At the same time, the controller will also compare the real-time pressure data with the preset pressure threshold to determine the patient's weight information. By comparing the real-time pressure data with the preset pressure threshold, the controller can determine the patient's weight information. For example, if the real-time pressure data exceeds a preset high pressure threshold, it may mean that the patient is heavy; if the real-time pressure data is lower than a preset low pressure threshold, it may mean that the patient is light. Once the controller obtains the patient's height and weight information, it can calculate the actual amount of anesthetic the patient needs based on this information. This calculation process takes into account the individual differences of patients and ensures the accuracy of anesthesia.

[0059] The calculation formula for the above anesthetic dosage is:

[0060] D=k×W 0.75 ×H

[0061] Among them, D is the dosage of anesthetic; W is the patient's weight (unit: kg); H is the patient's height (unit: m); k is a constant (this constant will be adjusted in actual application according to factors such as the type of anesthetic, the patient's age and physical condition).

[0062] Next, the controller will send a drug instruction to the drug delivery module based on the calculation results. The metering pump in the drug delivery module will adjust its working state according to the instructions to control the delivery speed and amount of the anesthetic. The flow sensor on the infusion line will monitor the delivery speed in real time and compare it with the delivery speed of the metering pump. If the comparison results are inconsistent, it means that the delivery speed deviates from the preset value. At this time, the controller will adjust the working state of the metering pump in time to ensure the accuracy of the delivery.

[0063] During the whole process, the temperature monitoring component in the anesthetic storage module 9 is also working continuously. The temperature sensor monitors the storage temperature of the anesthetic agent in real time and compares it with the temperature threshold in the controller. If the real-time temperature data does not match the temperature threshold, the controller will send an alarm signal to remind medical staff to deal with it in time.

[0064] In addition, the life monitoring module 11 also monitors the patient's vital signs data in real time, including body temperature, heart rate, blood pressure and blood oxygen saturation, etc., which will be transmitted to the controller for analysis and processing. If the controller detects any abnormal vital signs data, such as a fast heart rate, low blood pressure, etc., it will immediately sound an alarm and may adjust the dosage and administration speed of the anesthetic agent as needed. In the event of any emergency, medical staff should immediately take appropriate measures, such as stopping medication, performing cardiopulmonary resuscitation, etc., to ensure the safety of the patient.

[0065] During the whole emergency treatment process, the medical staff can keep track of the patient's status, the dosage of the anesthetic agent, the administration speed, etc. by observing the display screen 10 and the operation panel on the controller. If the patient information or threshold needs to be manually adjusted, it can also be input through the operation panel.

[0066] Finally, when the treatment is over, medical staff can easily fold the treatment bed by moving the components for next use. The design of the entire device fully considers practicality and portability, providing strong support for pre-hospital emergency treatment of craniocerebral trauma.

[0067] Embodiment 2:

[0068] The difference from Example 1 is that it also includes an early warning component (not shown in the figure), which includes an indicator light and a buzzer, the indicator light is used to send different light signals, the buzzer is used to send different sound signals, and the indicator light and the buzzer are both connected to the controller signal. When the controller detects that any one of the real-time pressure data, the real-time medication speed and the real-time temperature data is abnormal, the controller gives the early warning component an instruction to send an alarm signal. For example, red indicates serious abnormalities, yellow indicates minor abnormalities, etc. At the same time, the buzzer will also send different sound signals, such as a rapid alarm sound indicating a serious abnormality, an intermittent alarm sound indicating a minor abnormality, etc.

[0069] The specific implementation process is as follows: When the controller detects that any of the real-time pressure data, real-time drug delivery speed and real-time temperature data is abnormal, the early warning component starts working. The indicator light emits different light signals, such as red for serious abnormalities and yellow for minor abnormalities. At the same time, the buzzer will also emit different sound signals, such as rapid alarm sounds for serious abnormalities and intermittent alarm sounds for minor abnormalities.

[0070] Medical staff should quickly determine the type and degree of abnormality based on the signal from the indicator light and buzzer, and take appropriate emergency treatment measures, such as checking the patient's position and posture, adjusting the drug administration speed and dosage, and checking the storage temperature of anesthetic drugs. In the event of serious abnormality or emergency, medical staff should immediately stop drug administration and perform emergency measures such as cardiopulmonary resuscitation to ensure the safety of the patient.

[0071] Embodiment 3:

[0072] The difference from Example 2 is that it also includes a wireless communication module, which is connected to the controller signal and is used to transmit the patient's vital signs data, anesthetic dosage, drug administration speed and alarm signals to the remote medical center in real time.

[0073] The specific implementation process is as follows: Ensure that the wireless communication module has been correctly installed inside the device and establishes a stable signal connection with the controller. Check the hardware connection and software configuration of the wireless communication module to ensure that it can work properly. According to the requirements of the telemedicine center, configure the network parameters of the wireless communication module, such as SSID (service set identifier), password, IP address, etc. Ensure that the wireless communication module can successfully connect to the specified wireless network or mobile communication network.

[0074] The controller collects the patient's vital signs data (such as body temperature, heart rate, blood pressure, blood oxygen saturation, etc.), anesthetic dosage, drug administration speed and other information in real time. The collected data is encapsulated into data packets, including source address, destination address, checksum and other information to ensure the integrity and reliability of the data. The wireless communication module sends the encapsulated data packets to the remote medical center through the wireless network. During the transmission process, the wireless communication module will select the best channel for data transmission to avoid interference with other devices.

[0075] Embodiment 4:

[0076] The difference from Example 3 is that an auxiliary component is installed on the bed board 1, and the auxiliary component includes a plurality of support frames 12 and limb restraint belts, which are fixedly connected to both sides of the bed board 1. The limb restraint belts are used to restrain the patient's limbs; the limb restraint belts should have a certain degree of elasticity and softness to adapt to patients of different body shapes and reduce discomfort during restraint. It also includes a vomit collection component (not shown in the figure), which is detachably connected to one side of the bed board 1.

[0077] The specific implementation process is as follows: fix the support frame 12 on both sides of the bed board 1 according to the preset position and angle. Ensure that the support frame 12 is stable and reliable, and can withstand the patient's weight and the force generated during movement. The design of the support frame 12 should take into account the patient's comfort and safety to avoid oppression or injury to the patient.

[0078] Fix the limb restraint belt to the support frame 12 on both sides of the bed board 1 to ensure that the restraint belt can firmly restrain the patient's limbs. When using the limb restraint belt, the tightness of the restraint belt should be adjusted according to the patient's specific situation and needs to ensure that it can limit the patient's range of motion without causing excessive restraint or harm to the patient. Medical staff should regularly check the fixation of the limb restraint belt and the patient's condition, and promptly detect and deal with any abnormal situation.

[0079] The vomit collection component is detachably connected to one side of the bed board 1 to ensure that the connection is firm and easy to disassemble and clean. The vomit collection component should have a certain capacity and sealing to prevent vomitus from overflowing or leaking. When the patient vomits, the medical staff should immediately turn the patient's head to one side of the vomit collection component so that the vomitus can be smoothly discharged into the vomit collection component. During the vomiting process, the medical staff should pay close attention to the patient's condition and the condition of the vomitus, and promptly detect and deal with any abnormalities. After the vomiting is over, the medical staff should clean up the vomitus in the vomit collection component in time and disinfect it to ensure that it can be maintained hygienic and safe the next time it is used.

[0080] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
