Description

Technical Field

[0001] The present invention relates to the technical field of infusion care, and in particular to an infusion device, and in particular to an intelligent infusion device and method. Background Art

[0002] Infusion therapy is one of the most common treatment methods in clinical practice. Pediatric care is more difficult than that for adults. Children have very poor self-control ability. When nurses give injections to children, they usually feel fear and do not cooperate with the nurses, crying, struggling, etc. In response to this phenomenon, nurses or caregivers will give children sufficient psychological comfort before infusion, and use toys or other methods to distract their attention in order to complete the puncture. Furthermore, since the infusion speed for children is slower, the entire infusion process is usually longer, and children are active and prone to impatience. Therefore, during the infusion process, children will unconsciously move or grab the infusion tube, which will lead to needle dislocation, leakage, bulging, and redness and swelling at the infusion site. Studies have shown that during intravenous infusion in children, the infusion leakage rate reaches 5.6% (Li Yundan & Zhang Li. (2019). Analysis of causes and nursing countermeasures for intravenous infusion leakage in children. Laboratory Medicine and Clinical (09), 1280-1281); the infusion site where leakage occurred during the infusion process showed local swelling and tenderness (Liao Jihong, He Dan, Meng Caiying & Yang Li. (2010). Analysis of causes and nursing countermeasures for peripheral intravenous infusion leakage in 46 critically ill patients. Chinese Journal of Misdiagnosis (23), 5693). In some cases, such as when the pediatric department is particularly busy, nurses usually adjust the drug drip rate according to experience or doctor's orders. At this time, the drip rate may not match the child's acceptance. Children cannot clearly express their discomfort or pain, so they are more likely to cry or move their bodies drastically.

[0003] CN109157708A discloses an infusion device specially used for children's infusion, which includes a fixing belt, a fixing box at one end of the fixing belt, two U-shaped channels inside the fixing belt, a fixing belt inside the U-shaped channel, a fixing device inside the fixing belt fixing box, and a fixing device that prevents the fixing belt from moving again by pressure, thereby ensuring that the needle will not fall when the child moves his arm. At the same time, an arm anti-slip and anti-squeezing device is provided below the fixing belt, and the arm anti-slip and anti-squeezing device is to reduce the friction of the fixing belt directly on the child's arm by using an air bag, and can also prevent the fixing from being too tight, thereby reducing the damage to the child's arm. Although the device can fix the child's hand to be infused in a specific position, it can only be used for hand infusion, not for intravenous infusion of other parts, and does not consider the problem that long-term fixation will increase the child's discomfort. Due to long-term fixation, the child's hand will cause it to struggle more strongly. When the child's hand is stuck in the air bag, the pressure of the local vein will increase and the blood return will be blocked, so the medicine in the infusion tube cannot be infused into the blood vessel.

[0004] CN113058100A discloses a child infusion accompanying system, which includes an Internet of Things and a control system, a cloud server, a client APP, an intelligent speaker, a liquid level detection alarm device, a liquid level detection device and a steering gear locking device. The Internet of Things and the control system include a main control chip, a liquid level detection circuit of a liquid storage bottle, an Internet of Things module, a power module, a liquid crystal display module, a steering gear drive circuit, a liquid level alarm circuit of a liquid storage bottle and a voice playback module, and the liquid level detection circuit of the liquid storage bottle and the liquid level detection device are electrically connected. During the process of child infusion, the child can interact with the set intelligent speaker and the liquid crystal display module to achieve the purpose of distracting the child's attention from the infusion. The accompanying system can reduce the resistance of the child's infusion, but during the infusion process, the child's activities may still cause the needle to fall out, for example, the infusion tube accidentally rubs against the clothes on the body and causes the needle to fall out of the blood vessel, but the needle is still on the back of the hand, which is easy to be ignored by the accompanying person.

[0005] In addition to the above, in the existing intravenous infusion treatment process, the tasks of medical staff are quite heavy, and many of the tasks are interference situations. A study used an intravenous infusion task observation form to record the execution and interference of intravenous infusion tasks in 240 shifts. The results showed that nurses performed 852 tasks in total, with a total time of 3,181.29 minutes, during which 1,487 interferences occurred, an average of 1 every 2.14 minutes, and the total interference time was 612.77 minutes, accounting for about 19.30% of the total task time (Shang Jing. (2022). Master's degree in research on the influencing factors of nurses' psychological load and safety performance in the context of intravenous infusion tasks (dissertation, Naval Medical University of the People's Liberation Army of China)). In pediatric nursing, children may experience exudation or swelling at the infusion site. Parents are worried and unable to judge the current situation. Once there is a situation, they send prompt information to the nurse station or go directly to the doctor. Under normal or non-emergency circumstances, this operation significantly increases the ineffective workload of medical staff. The prior art cannot accurately determine whether to send a prompt message to medical staff according to the exudation or swelling that occurs during infusion, or cannot distinguish what type of prompt message to send.

[0006] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0007] In terms of child infusion care, the prior art provides a variety of child-specific infusion devices or systems to solve problems such as needle slippage and leakage caused by children's restlessness and struggle. For example, the current infusion cabin has an overall structure of an arc-shaped structure with a cartoon shape. The infusion cabin reduces the difficulty of needle insertion and the number of movements during the infusion process by setting a cartoon shape to divert children's attention, thereby achieving the purpose of reducing the infusion extravasation rate and re-injection rate. However, during the infusion process, since children will carry out certain activities, exudation may still occur. The prior art cannot distinguish whether the exudation phenomenon stops after a small amount of exudation at the beginning or whether the needle slips due to the activities of the child during the infusion. It cannot provide effective reminders for specific situations, so invalid reminders or false alarms are prone to occur when monitoring the infusion process of children.

[0008] In view of the shortcomings of the prior art, the present invention provides an infusion device, which includes: a cabin providing an infusion space for a child; a monitoring unit arranged in the cabin for real-time collection of image data of the infusion site of the child; an output unit arranged in the cabin and / or at the medical end for issuing prompt information, and a processing unit respectively connected to the monitoring unit and the output unit. The processing unit controls the output unit to issue prompt information according to the drug leakage of the infusion site and / or the swelling of the infusion site reflected by the image data collected by the monitoring unit. The processing unit is configured to: when the image data initially collected by the monitoring unit reflects the occurrence of exudation at the infusion site and / or swelling at the infusion site, control the output unit to prompt the caregiver to bring the child's infusion site close to the monitoring unit for the first fine collection, wherein the processing unit is configured to: according to the swelling coverage and / or exudation volume reflected by the first finely collected image, control the output unit to issue prompt information to the caregiver in the cabin for the second fine collection and / or issue prompt information to the medical end to intervene in the infusion child.

[0009] Technical effect: This technical solution provides a closed or semi-closed cabin for children receiving infusion. On the one hand, the cabin as an infusion space can reduce the interference of the external environment on the infusion child during the infusion process, and reduce the anxiety and discomfort caused by environmental discomfort. On the other hand, the monitoring unit installed in the cabin can perform preliminary collection and fine collection respectively, reducing the probability of false alarms, centrally monitoring the infusion site of the child, and improving the accuracy and real-time nature of monitoring. The processing unit can timely control the output unit to prompt the caregiver or medical staff to intervene in the child to ensure the safety of the infusion process.

[0010] In particular, the monitoring unit in the cabin collects image data of the infusion site in real time. Since there is a certain distance between the infusion site and the monitoring unit when the child is receiving an infusion, and the infusion site of the child will move or shake, the initially collected image may have errors, for example, the collected image is suspected of exudation and / or swelling, or reflects the existence of exudation and / or swelling at the infusion site, but cannot be quantified. When the initially collected image is identified as exudation and / or swelling, the processing unit controls the output unit to first send a prompt message to the caregiver, reminding the caregiver to bring the child's infusion site close to the monitoring unit, and to perform the first fine image acquisition in a manner that keeps the infusion site still. The monitoring unit can capture subtle changes, such as the degree of skin swelling, the range of swelling coverage, the amount of exudate, and other data. The first fine image acquisition provides clear visual information, helping the processing unit to perform accurate image analysis and judgment, thereby improving the accuracy of monitoring. This setting can reduce the probability of the device issuing a false alarm. Compared with the defect of the prior art that information is sent to medical staff upon preliminary identification of suspected exudation and / or swelling, this technical solution can proceed to the next step after confirming the actual situation of the infusion site, and select the reminder objects and intervention measures in a targeted manner.

[0011] In addition, after the processing unit accurately obtains the information of the swelling coverage and / or the amount of exudate for the first time, it makes a judgment to confirm whether to wait for the preset time for the next fine image acquisition or directly notify the medical staff to intervene in the infused child. This setting can optimize the nursing process and reduce the ineffective work of medical staff while confirming the safety of the child. The present invention provides a highly automated, responsive, and risk-oriented monitoring system for the infusion process. The device effectively transmits key information to the caregivers and medical staff, and guides them to take appropriate monitoring and intervention measures in a timely manner through intelligent prompts and warnings, ensuring that the infusion process is safer and improving the overall nursing efficiency.

[0012] According to a preferred embodiment, the processing unit controls the output unit in the cabin and / or the medical end to send a prompt message or warning message according to the amount of exudate at the infusion site, the swelling coverage area and / or the titration rate of the infusion.

[0013] Technical effect: The amount of exudate and the area covered by swelling are important indicators for assessing whether there is an abnormality at the infusion site. These indicators can help detect abnormalities at the infusion site as early as possible. Further combined with the monitoring data of the titration rate, the device can help medical staff determine whether exudate and swelling are caused by improper dripping rate. In some special cases, due to individual differences in children, even if the nurse sets the titration rate for the child according to the theoretical prescribed value, some children's acceptance of some drugs does not match the current titration rate, so exudate or swelling occurs at the infusion site, and the child also feels uncomfortable. Combining the three indicators helps to analyze the cause of exudate or swelling in advance. When the titration rate is too fast, the liquid leaks into the surrounding tissues, causing swelling and exudate. At this time, the titration rate can be adjusted first and observed continuously; if it is caused by the needle coming out of the vein (the liquid medicine no longer flows into the vein, the pressure in the pipeline decreases, and the dripping rate slows down), the titration rate will slow down or stop. In this case, the needle needs to be removed and re-punctured. Therefore, the present invention can send out specific prompt information or warning information in a targeted manner, reduce the ineffective work of medical staff, and reduce the probability of re-puncture in children.

[0014] According to a preferred embodiment, the processing unit is configured as follows: when the amount of exudate reflected by the image data of the first fine collection is less than the exudate amount threshold, the swelling coverage area is less than the preset area threshold, and the titration rate of the infusion is within the preset speed range, the output unit in the control cabin sends a prompt message to the caregiver to perform a second fine collection at the first interval time.

[0015] Technical effect: After the present invention determines that there is exudate and swelling through preliminary collection, it can prompt the caregiver to bring the child's infusion site close to the monitoring unit for the first fine collection. This operation can quantify the amount of exudate and the swelling coverage area to determine the severity. Specifically, the collected data is compared with the exudate volume threshold and the swelling coverage area threshold, and the processing unit can evaluate the risk level of the current infusion site. If both are less than the corresponding threshold, it indicates that it is currently in a low-risk state and can be continuously observed. Once the monitored data shows any trend approaching or exceeding the threshold, the output unit can promptly issue an early warning to the caregiver and guide the next step, such as performing a second fine collection or directly notifying the medical staff. In the case of a second fine collection, the processing unit sets a reasonable first interval time to determine when to perform the second fine collection. The setting of this interval time allows the caregiver to monitor the infusion in an orderly manner without affecting the normal activities of the child. When all monitoring indicators are within the normal range, the output unit will not disturb the caregiver or medical staff for no reason. This setting can reduce unnecessary intervention and reduce the anxiety of the caregiver, while improving the efficiency of the use of medical resources.

[0016] On the other hand, after receiving the prompt information, the caregivers can pay more attention to the infusion process, and then respond immediately when any problems arise, thereby enhancing the overall quality of monitoring. In addition, the present invention promotes the accuracy of data acquisition for continuous monitoring by setting up an operation for the caregiver to perform a second fine collection of the infusion site after the first interval. At the same time, the processing unit can perform multi-dimensional analysis, such as calculating the rate of exudation and the speed of change of the swelling coverage area through the data collected twice. This is crucial to the safety of infusion for children, especially when medical staff are not present. In particular, the rate of exudation and the speed of change of the swelling coverage area reflected by the data collected twice can help doctors judge the progression of the child's disease and help doctors make correct medical decisions.

[0017] According to a preferred embodiment, the processing unit is configured to: control the output unit of the medical end to send a first warning message to the medical staff that the titration rate may be too fast when the second finely collected image data reflects an increase in the amount of exudate and an expansion of the swelling coverage area, and the titration rate of the infusion is within a preset speed range, compared to the amount of exudate and the swelling coverage area reflected by the first finely collected image data.

[0018] Technical effect: Through the image data collected in detail for the first and second times, the processing unit can accurately track the changes in the amount of exudate and the area covered by swelling. If the data collected for the second time reflects an increase in the amount of exudate and an expansion of the area covered by swelling, it indicates that the abnormal situation during the infusion process has intensified. At the same time, the processing unit does not rely solely on a single parameter to make a decision, but conducts a comprehensive analysis in combination with the current titration rate. Although the titration rate is within the preset speed range, the amount of exudate increases and the area covered by swelling increases at the infusion site. Therefore, the processing unit analyzes that it may be due to the excessive titration rate that causes the vein to be unable to withstand excessive liquid pressure and leakage occurs, and the expansion of the swelling coverage area further proves the severity of the exudate. According to the current severity, the processing unit analyzes that medical staff are required to come to handle it, that is, the output unit of the medical end is controlled to send the first warning information that the titration rate may be too fast to the medical staff. Medical staff can be informed of the abnormal situation during the infusion process at the first time, and they can quickly evaluate and make decisions, such as adjusting the titration rate or relocating the needle. The early warning function of the present invention significantly improves the response speed of medical staff and reduces the probability of infusion complications caused by exudate and swelling.

[0019] According to a preferred embodiment, the processing unit is configured as follows: when the image data of the second fine collection reflects that the amount of exudate and the area covered by swelling are unchanged compared to the amount of exudate and the area covered by swelling reflected by the image data of the first fine collection, and the titration rate of the infusion is within a preset speed range, the output unit in the control cabin sends a reminder message to the caregiver to perform a third fine collection at a second interval.

[0020] According to a preferred embodiment, the duration of the second interval is greater than the duration of the first interval.

[0021] Technical effect: When the data collected for the second time shows that these two indicators have not changed, it indicates that the infusion process is currently stable, and there is no new exudate or swelling. The processing unit can dynamically adjust the monitoring frequency according to the current monitoring results. By reducing unnecessary monitoring processes, the purpose of optimizing resource allocation is achieved, including reducing the workload of the accompanying person and the computing resource consumption of the device itself.

[0022] The length of the second interval is greater than that of the first interval, indicating that the processing unit can reasonably set the time interval for precise collection according to the stability of the infusion process. This setting not only ensures continuous monitoring of the infusion process, but also avoids overly frequent monitoring, reduces the workload of caregivers, and improves their participation and sense of responsibility in the infusion process.

[0023] According to a preferred embodiment, the processing unit is configured to: control the output unit of the medical end to send a second warning message to the medical staff that the needle has come out of the vein during the infusion process when the second finely collected image data reflects an increase in the amount of exudate and an increase in the area covered by swelling, while the titration rate of the infusion is lower than the lower limit of the preset speed, compared to the amount of exudate and the area covered by swelling reflected by the first finely collected image data.

[0024] Technical effect: The data collected for the second time showed that the amount of exudate and the area covered by swelling continued to expand, and the titration rate of the infusion was lower than the lower limit of the preset speed, indicating that the needle may have dislocated from the vein, causing the liquid to leak into the surrounding tissue. The processing unit transmits key information to medical staff through the output unit on the medical end. This efficient information transmission mechanism ensures that medical staff can promptly understand abnormal situations during the infusion process and respond immediately.

[0025] According to a preferred embodiment, the processing unit is configured to: when the amount of exudate reflected by the first finely collected image data is less than the exudate amount threshold, the swelling coverage area is greater than the preset area threshold, and the titration rate of the infusion is within the preset speed range, control the output unit of the medical end to send a third warning message to the medical staff that the child receiving the infusion may have an inflammatory reaction or an allergic reaction.

[0026] Technical effect: The first finely collected image data detected that the amount of exudate at the infusion site was less than the exudate threshold, but the swelling coverage area was greater than the preset area threshold. This combination may indicate that the child has an inflammatory reaction or an allergic reaction. During the infusion process, mechanical damage or inflammatory reaction affects the function of the lymphatic system, resulting in the inability of tissue fluid to return in time, causing local swelling; children's immune systems are sensitive and prone to allergic reactions to infusion drugs, materials, etc.; or when the infusion needle pierces the skin and enters the vein, the body may regard this as an invasion, thereby triggering a local inflammatory reaction. Although the amount of fluid exudation is not large, the swelling area will continue to expand. In this case, the processing unit will issue a precise early warning to ensure that medical staff can intervene and deal with the problem at an early stage to prevent the situation from further deteriorating.

[0027] According to a preferred embodiment, the processing unit is configured to: when the amount of exudate reflected by the first finely collected image data is greater than the exudate amount threshold, the swelling coverage area is greater than the preset area threshold, and the titration rate of the infusion is lower than the lower limit of the preset speed, control the output unit of the medical end to send a fourth warning message to the medical staff that the needle has come out of the vein during the infusion process and the exudate is serious.

[0028] Technical effect: The image data collected for the first time detected that the amount of exudate was greater than the exudate threshold, the swelling coverage area was greater than the preset area threshold, and the titration rate of the infusion was lower than the lower limit of the preset speed. The amount of exudate was greater than the exudate threshold, indicating that a large amount of infusion liquid had leaked into the surrounding tissues. The swelling coverage area was greater than the preset threshold, indicating that the exudate had caused a significant local reaction, which may be accompanied by symptoms such as pain and redness. The titration rate was lower than the preset speed lower limit, which may indicate that the infusion was obstructed, further proving that the needle had come out of the vein. These indicators together indicate that the needle may have come out of the vein and the liquid has leaked into the surrounding tissues, and the problem is more serious. A large amount of exudate may cause local tissue damage and the infusion drug does not achieve the expected effect. This immediate warning mechanism ensures that medical staff can be informed of abnormal conditions in the shortest time and take corresponding measures quickly. Especially during particularly busy periods, medical staff can go to the corresponding children to intervene according to the emergency situation, reducing the probability of medical accidents.

[0029] According to a preferred embodiment, before the infusion begins, the monitoring unit is also used to collect drug information of the child receiving the infusion, and the processing unit adaptively adjusts the preset speed range as a reference benchmark based on the drug information. At the same time, the drug information can also serve as a basis for changing the severity of the prompt information or warning information.

[0030] According to a preferred embodiment, the processing unit is configured to generate corresponding logs and store them in a database based on the swelling coverage and / or the amount of exudate reflected by the first finely collected image data and / or the second finely collected image data for subsequent analysis and reference.

[0031] Technical effect: The processing unit generates detailed log records (including key information such as swelling coverage and exudate volume) based on the first and / or second finely collected image data. Fine data collection and storage ensure the accuracy and completeness of the records, providing a solid foundation for subsequent analysis. The complete records can fully reflect the changes in swelling and exudate during each infusion process, providing rich data resources for long-term monitoring and analysis. Based on these data resources, medical staff and researchers can identify potential patterns and trends in the infusion process, such as the relationship between a certain drug or specific operation steps and swelling and exudate conditions, thereby optimizing the infusion process.

[0032] Secondly, by analyzing log data, medical institutions can continuously improve nursing plans and operating procedures. For example, they can identify situations where needle dislocation or severe exudation is likely to occur, and then provide targeted training for medical staff so that when these abnormal situations occur, medical staff can take appropriate preventive measures in a timely manner, thereby improving the overall quality of care.

[0033] In addition, detailed historical records enable medical staff to develop personalized treatment and care based on the specific circumstances of each child. For example, by analyzing the patient's past infusion records, it is possible to more accurately determine whether a treatment plan is suitable for the patient and optimize the treatment effect.

[0034] According to a preferred embodiment, the infusion device further comprises a temperature sensor for detecting the body temperature or the skin temperature of the infusion site.

[0035] According to a preferred embodiment, the amount of exudate and the swelling coverage area of ​​the infusion site can be reflected by the marking on the tape that fixes the needle.

[0036] Another aspect of the present invention provides an infusion method, which is implemented by the infusion system provided by the first aspect of the present invention, and the method includes the following steps: collecting image data of the infusion site of the child; controlling the output unit to issue a prompt message based on the drug leakage and / or swelling of the infusion site reflected by the image data collected by the monitoring unit.

[0037] The present invention provides an infusion device that is more suitable for children. The design of the cabin in the infusion device optimizes the infusion environment, making the infusion process for children private (privacy protection), entertaining and interesting. The cabin provides a certain degree of privacy for children, reducing the sense of uneasiness caused by children being exposed to the sight of others. The infusion stand in the cabin is easy to move, and the infusion position can be flexibly adjusted according to the range of activities of the children, reducing the restrictions on children due to infusion. Cartoon patterns, colorful design elements or interactive lights are added to the inner wall of the cabin. This design increases the fun of infusion, attracts children's attention, and reduces the behavior of children pulling the infusion tube due to fear or anxiety. At the same time, the device uses an intelligent infusion monitoring system to monitor the infusion process of children, promptly discover possible drug extravasation, improper drip rate, etc., reduce the extravasation rate and re-injection rate of children's infusion, and ensure the safety of children's infusion.

[0044] The following is a detailed description with reference to the accompanying drawings.

[0045] In the present invention, preliminary acquisition refers to the acquisition of images when there is a certain distance between the infusion site of the child receiving infusion and the monitoring unit 200, and the infusion site may be in an active state. Fine acquisition refers to the acquisition of images of the infusion site when the caregiver controls the infusion site of the child receiving infusion to be close to the monitoring unit 200 and keeps the infusion site still.

[0046] The exudate volume threshold, preset area threshold and preset speed range of the titration rate are critical values ​​set by the doctor based on the child's specific situation, clinical response and long-term work experience, and are used to determine whether it is necessary to send a prompt message or warning message.

[0047] For pediatric infusion, the specific titration rate will be determined based on the individual needs of the patient, the doctor's prescription and the specific medical condition. Generally speaking, the drip rate is measured in drops per minute (dpm), also referred to as the titration rate in the present invention. Children's fluid capacity and tolerance are different from those of adults. The following are some common drip rate ranges for children: the drip rate is calculated according to the child's weight, such as 4 to 6 ml of maintenance fluid per kilogram of body weight per hour; for newborns or patients who need to carefully control the fluid infusion rate (such as heart patients), only a few drops per minute.

[0048] Example 1

[0049] This embodiment provides an infusion device, which is particularly an infusion device for children. The device is particularly suitable for particularly busy periods of time in pediatrics, such as the annual flu season, the peak period of allergies, the peak period of infectious diseases, etc., when the number of children who get sick increases significantly. The closed or semi-closed infusion space formed by the cabin 100 in the children's infusion device can reduce the chance of infection. The intelligent monitoring and graded reminder / warning system composed of the monitoring unit 200, the processing unit 400 and the output unit 300 can not only ensure the safety of the infusion process, but also effectively reduce the workload of doctors and nurses in pediatric care.

[0050] The pediatric infusion device includes a cabin 100, a monitoring unit 200, an output unit 300 and a processing unit 400. Figure 1 As shown. Preferably, the cabin 100 can be set as a closed or semi-closed structure, which provides an infusion space for children. The interior of the cabin 100 is decorated as a childlike environment, and the inner wall of the cabin 100 is painted with colorful cartoon characters and backgrounds, such as bears, rabbits, superheroes, etc. Some soft dolls and plush toys are placed in the cabin 100. These toys can not only be played by children, but also distract their attention during the infusion process, so that they can remain calm and relaxed. Preferably, a plurality of interactive devices with cartoon characters are arranged in the cabin 100. For example, some clearly marked prompt devices are arranged at different positions in the cabin 100. When the caregiver is required to bring the child's infusion site close to the monitoring unit 200, these devices will emit brightly colored light signals or play gentle prompt sounds, so that the caregiver can quickly find the target location, such as Figure 4As shown. The prompt device is, for example, a cartoon doll that can make sounds or light up (such as a bear doctor or a superhero nurse) to guide the caregiver to accurately place the child's infusion site in the correct position to successfully complete the fine image acquisition. Preferably, the cabin 100 is also equipped with a simple interactive game device, such as a button-type music box or light show. When the child receiving the infusion presses the button, an interesting sound or light effect will be emitted to further attract their attention.

[0051] The monitoring unit 200 is disposed in the cabin 100, and is used to collect image data of the infusion site of the child in real time. The monitoring unit 200 is connected to the processing unit 400 for communication, so as to send the collected data to the processing unit 400. Specifically, the monitoring unit 200 is connected to the processing unit 400 by wire or wireless means, for example, by Ethernet, Wi-Fi, LTE / 5G, etc.

[0052] Preferably, the monitoring unit 200 can be a high-resolution camera. Preferably, at least two high-resolution cameras are arranged in the cabin 100. Preferably, three high-resolution cameras are arranged in the cabin 100. The three high-resolution cameras can cover the three main angles of the front, back and side of the infusion site respectively. This setting ensures that any changes and details of any angle can be captured, thereby improving the detection accuracy of drug leakage and swelling. Secondly, children may move during the infusion process, and accordingly, the position of the infusion site will change. The setting of multiple cameras can adapt to such changes and ensure that no matter how the infusion site moves, it can continue to monitor. Thirdly, multiple cameras can provide redundant data. If a camera fails or is blocked, other cameras can still continue to monitor. This setting improves the reliability and stability of the system in acquiring data. After the puncture stage, the normal infusion stage in which the drug drip rate is stable within the set range is entered. The monitoring unit 200 can transmit the collected images to the back-end processing system through the real-time video stream. The back-end processing system pre-processes the video stream and identifies and extracts the area of ​​the infusion site (for example, using U-Net or Mask R-CNN algorithm), and further compares the regional image of the infusion site captured in real time with the reference image under the normal infusion state to calculate the difference. When the difference exceeds the set threshold, it can be judged that the area has abnormal conditions such as exudation and swelling. Preferably, the processing unit 400 can be a computer system equipped in the central monitoring station of the hospital, which is used to identify and integrate the monitoring data. The processing unit 400 is connected to the output unit 300 in communication. Specifically, the processing unit 400 is connected to the output unit 300 by wired or wireless means, for example, by Ethernet, Wi-Fi, LTE / 5G, etc. The processing unit 400 sends a control instruction to the output unit 300, and the output unit 300 executes the instruction after receiving the instruction.

[0053] Preferably, the output unit 300 includes an output unit 300 disposed in the cabin 100 and / or an output unit 300 disposed at the medical end. Preferably, the output unit 300 disposed in the cabin 100 can be arranged near the high-resolution camera in the form of a doll-shaped speaker. Preferably, the output unit 300 disposed at the medical end can be a mobile device associated with the doctor or nurse responsible for the infusion of the child, such as a mobile phone, a smart watch, a pager, or a call bell of a nurse station.

[0054] The processing unit 400 is used to process the image data, and control the output unit 300 to send a prompt message according to the drug leakage at the infusion site and / or the swelling at the infusion site reflected by the data. According to a preferred embodiment, the processing unit 400 is configured to: when the image data initially collected by the monitoring unit 200 reflects drug leakage at the infusion site and / or swelling at the infusion site, control the output unit 300 to prompt the caregiver to bring the child's infusion site closer to the monitoring unit 200 information for the first fine collection. According to a preferred embodiment, the processing unit 400 is configured to: according to the swelling coverage and / or the amount of exudate reflected by the first finely collected image, control the output unit 300 to send a prompt message to the caregiver in the cabin 100 to perform a second fine collection and / or send a prompt message to the medical end to intervene in the infused child.

[0055] The processing unit 400 can control the output unit 300 in the cabin 100 and / or at the medical end to send out prompt information or warning information according to the amount of exudate at the infusion site, the swelling coverage area and / or the titration rate of the infusion.

[0056] According to a preferred embodiment, the child infusion device of this embodiment can complete the information prompt through the experience table (Table 1). Here, the specific operation process of the child infusion device is explained by taking the infusion monitoring of children aged 1 to 3 as an example. It should be understood that the data is schematic, and these thresholds should be adjusted according to the specific guidelines and clinical experience of the medical institution. In actual operation, doctors and nurses will judge whether it is necessary to adjust the infusion rate or take other measures according to the actual situation and reaction of the child.

[0057] Table 1

[0058]

[0059] A high-resolution camera (e.g., a camera with a high frame rate of 30fps or more) captures the data of the movement of the droplets in the infusion titration chamber (drip pot, drip bucket), and the monitoring unit 200 collects the data and sends the data to the processing unit 400. The processing unit 400 (e.g., a computer, a single-board computer) processes and analyzes the image or video data captured by the camera. Specifically, the processing unit 400 pre-processes the captured image or video data, such as denoising, contrast enhancement, etc., and then uses an image processing algorithm to detect the position and movement trajectory of the droplets. OpenCV and other open source computer vision libraries can be used for image processing and analysis.

[0060] The amount of exudate and the area covered by swelling at the infusion site can be reflected by the markings on the tape that fixes the needle, such as scales or other markings on the tape. Specifically, a high-resolution camera will capture the tape that fixes the needle and the surrounding area, including the scale markings and the infusion site; the processing unit 400 pre-processes the collected image, such as denoising, contrast enhancement, etc., to ensure that the scale markings are clear and visible; the processing unit 400 uses image recognition technology to identify and locate the scale markings on the tape 2. The processing unit 400 analyzes the distribution of exudate in the image and estimates the amount of exudate based on the scale range covered by the exudate (the wet area appears in different colors, such as brighter or darker). For example, if the exudate covers the range from scale 1 to scale 5, the processing unit 400 can calculate the amount of exudate based on the unit of the scale (such as each scale represents 0.1 ml). Similarly, the processing unit 400 detects the swelling area of ​​the infusion site and compares it with the scale mark; the processing unit 400 estimates the swelling coverage area by calculating the number of scales covered by the swelling area. For example, if the swelling area covers the range from scale A to scale D, the processing unit 400 can calculate the swelling coverage area according to the unit of the scale (such as each scale represents 1 square centimeter). Finally, based on the calculated amount of exudate and the swelling coverage area, the processing unit 400 controls the output unit 300 to issue a corresponding prompt message or warning message. The following is an example of identifying swelling at the infusion site, which generally includes image acquisition, image preprocessing, feature extraction, model training and recognition, analysis and prompting. Specifically, a high-resolution camera or a dedicated medical camera captures images of the infusion site in real time; after image acquisition, preprocessing (noise reduction, contrast enhancement, color correction) is performed to improve image quality and recognition accuracy; key features in the image are extracted through computer vision algorithms, including color changes (swollen sites usually show color changes different from normal skin, such as redness and swelling), shape changes (swollen sites may have abnormal bulges or extensions), and texture changes (texture analysis methods are used to identify changes on the skin surface); machine learning or deep learning models are used to identify swelling, and commonly used methods include convolutional neural networks (trained by a large amount of annotated image data, convolutional neural networks can learn to identify swelling features), support vector machines (combined with extracted image features for classification, identifying swelling areas), and integrated learning methods (combining the advantages of multiple models to improve recognition accuracy and robustness); by analyzing the identified swelling area, it is compared with a preset area threshold. If the preset area threshold is exceeded, the system will automatically generate a prompt message or warning message to notify medical staff to conduct further inspection or intervention. According to a preferred embodiment, the pediatric infusion device can realize real-time monitoring of the infusion site, continuously acquire image data and analyze it. Once exudation, swelling or other abnormal conditions are identified, the output unit 300 will immediately issue a prompt or alarm to ensure that medical staff can intervene in time.The analysis process of exudate volume, drug information identification and analysis, and swelling coverage area is the same as before and will not be given as an example here.

[0061] Figure 2 Schematic diagram of the working process of the pediatric infusion device provided in this embodiment.

[0062] According to a preferred embodiment, the processing unit 400 is configured as follows: when the amount of exudate reflected by the image data of the first fine collection is less than the exudate amount threshold, the swelling coverage area is less than the preset area threshold, and the titration rate of the infusion is within the preset speed range, the output unit 300 in the control cabin 100 sends a prompt message to the caregiver to perform a second fine collection at the first interval time.

[0063] The processing unit 400 is configured to perform the following operations:

[0064] If V1<V threshold And A1<A threshold And Q preset ≤Q≤Q max ,

[0065] but:

[0066] The output unit 300 in the control cabin 100 sends a prompt message to the caregiver to perform a second fine collection at Δt1.

[0067] Wherein, V1 represents the amount of exudate collected in the first detailed collection; A1 represents the swelling coverage area collected in the first detailed collection; Q represents the titration rate of infusion; V threshold Indicates the threshold value of exudate amount; A threshold Indicates the threshold of the swelling coverage area (preset area threshold); Q preset Indicates the lower limit of the preset speed range; Q max represents the upper limit of the preset speed range; Δt1 represents the first time interval.

[0068] In the image captured by the monitoring unit 200, the time point corresponding to the image of the first appearance of the wet area is defined as the start time of the exudation. That is, the image data initially collected reflects the occurrence of drug exudation at the infusion site. Similarly, in the image captured by the monitoring unit 200, the time point corresponding to the image of the first appearance of a color change or a specific contour change at the infusion site is defined as the time of swelling occurrence. That is, the image data initially collected reflects the occurrence of swelling at the infusion site. Generally speaking, if exudation occurs during the infusion process, it is usually accompanied by the occurrence of swelling (the skin becomes tight and bulging).

[0069] The amount of exudate and / or swelling reflected by the image data preliminarily collected by the monitoring unit 200 serves as a basis for whether to perform a detailed collection operation.

[0070] The time interval between the start time of exudation and / or the time of swelling occurrence and the next fine collection by the monitoring unit 200 can reflect the change of the exudation area (moisture degree) and / or the change of the swelling coverage area (swelling degree). Similarly, the time interval between different fine collection actions can reflect the change of the exudation area (moisture degree) and / or the change of the swelling coverage area (swelling degree).

[0071] The preset interval time period can be adaptively adjusted according to the type of medicine.

[0072] According to a preferred embodiment, the processing unit 400 is configured to: control the output unit 300 of the medical end to send a first warning message to the medical staff that the titration rate may be too fast when the second finely collected image data reflects that the amount of exudate has increased, the area covered by swelling has expanded, and the titration rate of the infusion is within a preset speed range, compared to the amount of exudate and the area covered by swelling reflected by the first finely collected image data.

[0073] The processing unit 400 is configured to perform the following operations:

[0074] If V2>V1 and A2>A1 and Q preset ≤Q≤Q max ,

[0075] but:

[0076] The output unit 300 of the medical terminal is controlled to send a first warning message to the medical staff that the titration rate may be too fast.

[0077] Among them, V2 represents the amount of exudate collected in the second time, and A2 represents the swelling coverage area collected in the second time. The meanings of other symbols are the same as before and will not be repeated here.

[0078] According to a preferred embodiment, the processing unit 400 is configured to: when the second finely collected image data reflects no change in the amount of exudate and the area covered by swelling compared to the amount of exudate and the area covered by swelling reflected by the first finely collected image data, and the titration rate of the infusion is within a preset speed range, the output unit 300 in the control cabin 100 sends a prompt message to the caregiver to perform a third fine collection at a second interval. According to a preferred embodiment, the length of the second interval is greater than the length of the first interval.

[0079] The processing unit 400 is configured to perform the following operations:

[0080] If V2=V1 and A2=A1 and Q preset ≤Q≤Q max ,

[0081] but:

[0082] The output unit 300 in the control cabin 100 sends a reminder message to the caregiver to perform the third detailed collection at Δt2.

[0083] Among them, Δt2>Δt1,

[0084] Δt2 represents the second time interval. The meanings of other symbols are the same as before and will not be repeated here.

[0085] According to a preferred embodiment, the processing unit 400 is configured to: control the output unit 300 of the medical end to send a second warning message to the medical staff that the needle has come out of the vein during the infusion process when the second finely collected image data reflects an increase in the amount of exudate and an expansion in the area covered by the swelling, while the titration rate of the infusion is lower than the lower limit of the preset speed, compared to the amount of exudate and the area covered by the swelling reflected by the first finely collected image data.

[0086] The processing unit 400 is configured to perform the following operations:

[0087] If V2>V1 and A2>A1 and Q≤Q preset ,

[0088] but:

[0089] The output unit 300 of the control medical terminal sends a second warning message to the medical staff that the needle is out of the vein during the infusion process. The meaning of the symbols is the same as before and will not be repeated here.

[0090] According to a preferred embodiment, the processing unit 400 is configured to: when the amount of exudate reflected by the first finely collected image data is less than the exudate amount threshold, the swelling coverage area is greater than the preset area threshold, and the titration rate of the infusion is within the preset speed range, control the output unit 300 of the medical end to send a third warning message to the medical staff that the child receiving the infusion may have an inflammatory reaction or an allergic reaction.

[0091] The processing unit 400 is configured to perform the following operations:

[0092] If V1<V threshold And A1>A threshold And Q preset ≤Q≤Q max ,

[0093] but:

[0094] The output unit 300 of the control medical terminal sends a third warning message to the medical staff that the child receiving the infusion may have an inflammatory reaction or an allergic reaction. The meaning of the symbols is the same as before and will not be repeated here.

[0095] According to a preferred embodiment, the processing unit 400 is configured to: when the amount of exudate reflected by the first finely collected image data is greater than the exudate amount threshold, the swelling coverage area is greater than the preset area threshold, and the titration rate of the infusion is lower than the lower limit of the preset speed, control the output unit 300 of the medical end to send a fourth warning message to the medical staff that the needle has come out of the vein during the infusion process and the exudate is serious.

[0096] The processing unit 400 is configured to perform the following operations:

[0097] If V1>V threshold And A1>A threshold And Q<Q preset ,

[0098] but:

[0099] The output unit 300 of the control medical terminal sends a fourth warning message to the medical staff that the needle is out of the vein and the leakage is serious during the infusion process. The meaning of the symbols is the same as before and will not be repeated here.

[0100] According to a preferred embodiment, before the infusion begins, the monitoring unit 200 is also used to collect drug information of the child receiving the infusion, and the processing unit 400 adaptively adjusts the preset speed range serving as a reference benchmark based on the drug information. For example, the conventional titration rate of 0.9% sodium chloride injection (normal saline) is 10-20 drops / min (10-20 ml / h); the conventional titration rate of 5% glucose injection (glucose injection) is 5-10 drops / min (5-10 ml / h); the conventional titration rate of antibiotics (such as cephalosporins, penicillins) is 20-30 drops / min (20-30 ml / h); the conventional titration rate of electrolyte supplement solution (such as potassium chloride injection) is 10-20 drops / min (10-20 ml / h); the conventional titration rate of nutrient solution (such as fat emulsion injection, amino acid injection) is 1-2 ml / min; the conventional titration rate of chemotherapy drugs (such as cyclophosphamide, vincristine) is 20-60 drops / min (20-60 ml / h).

[0101] At the same time, drug information can also be used as a basis for changing the severity of prompt information or warning information. Some drugs may be more likely to cause swelling of the infusion site due to their irritation, allergic reactions and other problems. For example, penicillins and cephalosporins may sometimes cause local irritation or allergic reactions, resulting in redness and swelling of the infusion site; chemotherapy drugs such as vincristine and cyclophosphamide may cause local tissue damage due to their strong cytotoxicity; when transfusing blood or infusing plasma products, if a transfusion reaction occurs, it may cause symptoms such as redness, swelling, and fever at the infusion site. For different types of drug exudation and swelling of the infusion site during the infusion process, the emergency situation of medical treatment and medical staff are different. In some cases, only the nurse needs to change the infusion site; in other cases, a specialist is required to perform surgical intervention on the child. Therefore, according to the acquired drug information, the processing unit 400 can automatically adjust the severity of the prompt information or warning information to notify the medical staff who come to intervene in a targeted manner to avoid unexpected situations (such as infection, arrhythmia, etc.).

[0102] Preferably, after entering the cabin 100 , the nurse first aligns the information on the medicine bottle (bag) to be infused with the camera of the monitoring unit 200 to collect the medicine information.

[0103] According to a preferred embodiment, the processing unit 400 is configured to generate corresponding logs and store them in a database based on the swelling coverage and / or the amount of exudate reflected by the first finely collected image data and / or the second finely collected image data for subsequent analysis and reference.

[0104] According to a preferred embodiment, the children's infusion device also includes a temperature sensor, which is used to detect the body temperature or the skin temperature of the infusion site.

[0105] According to a preferred embodiment, the amount of exudate and the swelling coverage area of ​​the infusion site can be reflected by the marking on the tape that fixes the needle.

[0106] Example 2

[0107] This embodiment provides a specific structure of the cabin 100, and the contents repeated in the embodiment are not repeated. The cabin 100 includes an infusion stand 110, an infusion chair 130 (infusion bed), entertainment equipment and a monitoring unit 200, such as Figure 3As shown. Entertainment equipment such as some audio players. The infusion stand 110 includes a fixed base 111 and an infusion hanging rod 112 inserted into the fixed base 111. The infusion hanging rod 112 and the fixed base 111 can move relative to each other. Specifically, the infusion hanging rod 112 is a telescopic movable rod. A hook 114 is provided on the top of the infusion hanging rod 112, which is used to hang an infusion bottle or an infusion bag. A pulley 113 is provided under the fixed base 111, which is conducive to the adjustment of the infusion position. The overall structure of the cabin 100 can be an arc-shaped semi-enclosed structure. The inner wall of the cabin 100 is a cartoon background. The inner wall of the cabin 100 is provided with a buckle portion 115 for fixing the infusion tube 116, and this setting can reduce the probability of the infusion tube 116 being dragged. Preferably, three high-resolution cameras are respectively provided on the top of the cabin 100 with a cartoon background, and the infusion stand 110 is used as a fixed point, and the three high-resolution cameras are respectively installed directly above it (such as the top of the infusion stand 110), on the upper left and on the upper right. Preferably, the high-resolution camera shape can be designed to be the same or different cartoon shapes. A cartoon-shaped speaker (output unit 300) is installed on the inner wall of the cabin 100 for issuing prompt information. When the high-resolution camera is a different cartoon shape, the processing unit 400 controls the bear speaker to output prompt information including specific high-resolution camera shape information, so that the accompanying person can smoothly find the image capture direction when performing fine collection. Preferably, the cartoon-shaped camera is integrated with a flash. When the processing unit 400 sends a prompt information for fine collection to the accompanying person, the flash on the camera that collects the image emits a bright light, which is used to prompt the accompanying person to find the right direction. At the same time, the bright light it emits can also attract the attention of children. An LED light source 120 is provided on the upper part of the infusion stand 110, which provides a uniform and bright light source near the infusion stand 110, which is conducive to the high-resolution camera to accurately capture the titration rate. An infusion chair 130 is set next to the infusion stand 110. A storage slot 140 is provided next to the infusion chair 130, which is used to place cartoon toys.

[0108] Preferably, some clearly marked cartoon dolls are arranged at different positions on the inner wall of the cabin 100. These dolls can make sounds or light up to guide the caregiver to accurately place the child's infusion site in the correct position to successfully complete fine image acquisition.

[0109] The cabin 100 of this embodiment can bring children into a virtual entertainment world through sound, color, video, light changes, virtual scenes, etc. For example, soft music or natural sounds (birdsong, water flow, etc.) are used to distract the attention of children. The interior of the cabin 100 is mainly painted with warm and soothing colors, in which cameras, speakers and other equipment can be presented in cartoon images. Educational videos or cartoons suitable for children's age groups can also be played in the cabin 100. Use soft lights or adjustable two-way lighting systems to create a comfortable and peaceful environment. Virtual reality technology is used to provide children with an immersive entertainment experience. Children can wear VR helmets to participate in games or explore virtual environments. If the child likes space, a virtual scene of space exploration can be provided. These settings all help to attract the attention of children and make them relaxed, effectively diverting their attention from medical procedures. The cabin 100 adjusts the functions of various facilities in a timely manner according to the needs of the patient to alleviate the pain of intravenous puncture and infusion in children.

[0110] The small animals set in the infusion cabin 100 not only have a cute appearance, but also can play children's favorite music and videos. These small animals can play different content according to the age and preferences of the children, such as nursery rhymes, cartoons or educational videos. A control interface is set in the cabin 100, which allows parents to choose the content to be played according to the preferences and needs of the children, or to participate in interactive games with the children. Sound, light, audio and video, color, etc. divert the children's attention and further reduce the pain of intravenous puncture in children. The cabin 100 can sense the emotional changes of the children (such as crying), monitor the violent movement of the puncture site, etc. The cabin 100 is equipped with an advanced voice interaction system, which can actively communicate with the children when it detects crying, comfort and care for them, such as playing soothing voice messages, videos or asking questions to guide the children to participate in the interaction and divert their attention.

[0111] When a crying child is detected, the child infusion device can promptly control the output unit 300 in the cabin 100 to play cartoons, and the characters in the cartoons can communicate with the child and comfort the child. Preferably, the output unit 300 in the cabin 100 can also be set as a display device (such as a display screen, a TV, a tablet, etc.). The display screen can be set at the top of the cabin 100, and the processing unit 400 can automatically control the display screen at the top of the cabin 100 to play cartoons or other videos. Family members can switch various cartoons or audio and video by themselves through the control interface. The control interface can also be used as a drawing board. The control interface receives voice commands from family members or children (such as "I want to draw") or directly clicks on the drawing option on the control interface, and the control interface automatically calls out the drawing board.

[0112] The cabin 100 is also equipped with heat preservation facilities, and the temperature can be adjusted manually or automatically.

[0113] During infusion, the nurse shows the drug to be infused toward the camera so that the device can capture drug information and obtain drug properties. The infusion stand 110 is equipped with sensors to monitor the infusion status, such as drip rate and remaining drug volume. The device can automatically adjust the drip rate based on the drug properties, that is, intelligently adjust the drip rate. After the liquid medicine in the current infusion bottle / bag is infused, the device can send an alarm instruction to the output unit 300.

[0114] During the infusion process for children, it is crucial to ensure the consistency and safety of the infusion drip rate, especially when the children need to receive infusion in different positions or activities. The infusion stand 110 has an adjustable telescopic rod, which can be adjusted to a suitable height according to the height of the child or family members, or the infusion hanging rod 112 can be removed. The infusion stand 110 can automatically adjust the height according to the position of the child, keep the infusion bottle / bag roughly consistent with the heart level of the child, and reduce the change in drip rate caused by the height difference.

[0115] The cabin 100 is provided with a door that can open and close automatically. When the patient's family members are resting, the door of the cabin 100 is automatically closed, leaving half of the space for the nurse to inspect the patient's condition. The camera in the cabin 100 can capture drug extravasation, the remaining amount in the infusion bottle / bag, etc.

[0116] Preferably, an intelligent restraint device is provided in the cabin 100 to reduce the risk of the needle being accidentally pulled out or pulled. When the intelligent restraint device detects that the needle has fallen off or the puncture site has moved violently, the output unit 300 issues an alarm.

[0117] Preferably, the pediatric infusion device can also evaluate the phlebitis of the child, which includes an artificial intelligence evaluation system and various sensors (skin temperature sensor, pressure sensor, etc.). The sensor collects the physiological parameters of the child's infusion site, the camera captures the image of the infusion site, and detects signs of phlebitis such as redness, swelling, and hardening through image recognition technology. The device has a built-in phlebitis grading standard, and the symptoms are graded according to the internationally accepted phlebitis assessment scale (such as the INS standard). The processing unit 400 can analyze the collected data in real time, automatically evaluate the severity of phlebitis, and issue early warnings to medical staff in a timely manner. According to the evaluation results of phlebitis, the processing unit 400 can intelligently output the corresponding treatment plan, such as adjusting the infusion speed, changing the drug or infusion site. The processing unit 400 can also analyze the historical data of children's infusion to identify the patterns and risk factors of phlebitis.

[0118] According to a preferred embodiment, the pediatric infusion device can identify and analyze the amount of liquid exudation, the exudation area, the nature of the exuded drug, the exudation time, the temperature of the skin at the exudation site, the skin color, the pain level, etc. Specifically, a high-precision sensor or image analysis technology is used to measure the volume of the exuded liquid. An algorithm is developed to estimate the exudation area through image recognition and track changes by comparing time series images. The time point when the exudation occurs is recorded and the speed and pattern of the exudation development are analyzed. A drug database is integrated to analyze the properties of the exuded drug, such as pH value, chemical composition, irritation, etc. An infrared thermal imager is used to monitor the skin surface temperature and quickly identify abnormal temperature areas. The skin temperature change trend is analyzed to evaluate the severity of the exudation and the inflammatory response. An algorithm is developed to identify skin color changes and distinguish between normal and abnormal color areas. Image processing technology is applied to improve the accuracy of color recognition and reduce ambient light interference. Physiological signals such as heart rate and blood pressure are analyzed to indirectly evaluate pain reactions; or facial expression recognition technology is used to evaluate the pain level of children. The device can combine the exudation volume, exudation area, drug properties, time, skin temperature, color and pain level to conduct a comprehensive assessment and generate a detailed risk assessment report to provide decision support for medical staff. When potential drug extravasation or complication risks are detected, the processing unit 400 controls the output unit 300 to immediately issue an alarm.

[0119] In some cases, the nurse forgets to remove the tourniquet, and the tourniquet is tied on the limb for a long time. Under the cover of clothes, no one finds it, which can easily lead to obstructed blood circulation and limb necrosis. Therefore, the pediatric infusion device is equipped with an intelligent reminder function. When the nurse punctures, a reminder to remove the tourniquet is issued. In addition, a pressure and time sensor can be embedded in the tourniquet to monitor the tightness and use time of the tourniquet in real time. The tourniquet is connected to the processing unit 400 of the hospital or the mobile device of the medical staff via Bluetooth or Wi-Fi. The timing starts from the time the tourniquet is tied. Once the safe use time is exceeded, the device automatically triggers a reminder. Preferably, the pediatric infusion device is set with multiple levels of reminders. When the safe use time is approaching, the medical staff is slightly reminded by the indicator light or vibration module on the tourniquet. If the primary reminder is not responded to, the processing unit 400 issues a reminder in the output unit 300 of the cabin 100 through an audio or visual signal. When there is no response for a long time, the processing unit 400 automatically sends an emergency notification to the mobile device or workstation of the nurse in charge.

[0120] In summary, the sound, light, audio, mechanical, artificial intelligence, temperature and humidity adjustment and other settings in the pediatric infusion device improve the comfort of the child's infusion, reduce the pain of the child during the infusion process, and reduce the re-injection rate and extravasation rate. The child can be infused in the cabin 100. The advanced voice interaction system equipped in the cabin 100 allows human-computer interaction (voice dialogue, etc.), and the display screen in the cabin 100 can play videos. In addition, during the infusion process, the child's limbs can be mechanically restrained to prevent him from pulling the infusion tube 116 or the needle. The automatically openable and closing door of the cabin 100 can ensure the privacy of the child and allow the nurse to inspect the child's condition.

[0121] Example 3

[0122] In pediatric injection management, the drug injection process during which precipitation may occur needs to be strictly controlled, as precipitation may lead to serious adverse events or even death. In addition, the infusion rate and / or concentration (concentration can also be expressed as a function of the infusion rate) need to be controlled to avoid possible infusion reactions, thereby preventing drug toxicity (such as bone marrow suppression, hepatotoxicity, and nephrotoxicity). At the same time, in the process of controlling the infusion rate and / or concentration, attention should also be paid to the child's emotional fluctuations and behavior during infusion.

[0123] In order to manage the infusion behavior, the present embodiment provides a pediatric infusion device with a VR set device, wherein the VR set device, such as a VR helmet, includes a head-mounted display and a motion capture piece worn on the hand. The motion capture piece on the hand allows the child to trigger corresponding actions in the game to interact with the game. Another head-mounted display of the VR set device acts as a module of the output unit 300, which is used to send prompt information to the family members of the child at the corresponding infusion position. Another head-mounted display that interacts with the first head-mounted display worn by the child can prompt the family members of the child.

[0124] In this embodiment, the motion capture device is used in conjunction with the spatial positioning system at the infusion position to track the child's hand at the corresponding infusion position. VR suits are usually used in conjunction with a specific software platform, on which hospital managers can browse, download and launch games. The sensors and tracking technology inside the VR suit ensure that the signals of the head-mounted display and the holder are synchronized to provide a seamless gaming experience.

[0125] In view of the shortcomings of the existing technology, the device, in addition to the VR set equipment, also includes a first acquisition unit, which is used to monitor the drug drip rate during the child's infusion process; a second acquisition unit, which is used to monitor the activity change information of the child during the infusion process; and a third acquisition unit, which is used to monitor the drug deposition or concentration change information in the infusion tube.

[0126] The specific configuration of the device of this embodiment is as follows: after receiving the drug dripping rate information of "puncture completion infusion rate information" from the first acquisition unit, according to the current drug dripping rate provided by the first acquisition unit and the activity change information provided by the second acquisition unit, the opening and closing state of the third acquisition unit is controlled, and prompt information for managing the child's activities is sent to the child's family through the output unit 300, or early warning information for checking the status of the child is sent to the medical staff. In particular, when the drug dripping rate exceeds the preset dripping rate range, the third acquisition unit will be activated.

[0127] The drug drip rate information of the "puncture completion infusion rate information" is determined as follows: starting from an infusion rate of zero, it reaches a constant rate after an initial stable stage, and after the duration of the constant rate reaches a continuous steady-state stage, the first acquisition unit determines the current infusion rate information after reaching the continuous steady-state stage as the "puncture completion stage infusion rate information".

[0128] For a child at a specific infusion position, after receiving the drug information confirmed or provided by the medical staff, the processing unit 400 controls the first acquisition unit to collect and provide the current drug drip rate related to the child at the corresponding infusion position, and controls the second acquisition unit to collect and provide activity change information.

[0129] Only when the processing unit 400 analyzes and confirms that the current drug dripping rate and / or activity change information reflects that the child's activity behavior affects the drug dripping rate, the processing unit 400 controls the opening and closing state of the third acquisition unit, especially opens the third acquisition unit, and sends a prompt message of managing the child's activities to the child's family through the output unit 300, or sends a warning message of checking the child's status to the medical staff. In particular, when the drug dripping rate exceeds the preset dripping rate range, the third acquisition unit will be activated. By analyzing the concentration or deposition information provided by the third acquisition unit, the processing unit 400 selectively provides warning information and / or prompt information of the drug type related to the child at the corresponding infusion position through the output unit 300. The warning information and / or prompt information are provided by the processing unit 400 through the output unit 300 according to the information related to the activity behavior and drug type of the child at the corresponding infusion position. For example, information related to the drug type includes drugs with precipitation risks, drugs that require precise control of the infusion rate, or drugs that require attention to the emotions of the infusion patient.

[0130] The third acquisition unit of the device is a relatively expensive device in terms of hardware, and it is also software that consumes computing power. Through the design of this embodiment, it is not necessary to install and use the third acquisition unit for all infusion positions in the cabin 100 at the same time, but it can be selectively set for infusion positions with specific action risks and / or specific drug risks. This not only reduces the renovation cost of the relevant pediatric outpatient clinics, but also reduces the frequent alarms at the nurse station. It should be noted that the device does not need to include all of these units to function, and various functions can be achieved with the help of only one or several of the units.

[0131] The pediatric infusion device provided in this embodiment can ensure smooth execution from the puncture stage to the end of infusion, especially by using the VR set equipment to distract children's attention during the puncture stage, further reducing the erroneous evaluation in the subsequent infusion management process due to unsmooth or unsuccessful puncture in the early stage.

[0132] When the medical care end confirms before infusion that the drug is a drug with a precipitation risk, requires precise control of the infusion speed, or requires attention to the mood of the infused patient, the processing unit 400 generates corresponding warning information through the information prompt module. In this embodiment, the adverse effects that may be caused by different types of drugs during the infusion process are distinguished, and the information prompt module specifically issues warning information with different meanings. Specifically, some drugs may cause precipitation or concentration changes in the infusion drugs, and other drugs may cause emotional changes in the children. The processing unit 400 can distinguish the adverse effects that may be caused by different drugs, and control the information prompt module to issue warning information in a targeted manner. This not only reduces the probability of false alarms and reduces the ineffective work of medical staff, but also distinguishes the warning information, so that medical staff can grasp the current situation of the children in advance and ensure that intervention measures are taken in time.

[0133] The processing unit 400 selectively sets the monitoring mode for controlling the third acquisition unit according to the drug type provided by the medical end, wherein the drugs include drugs with precipitation risks, drugs that require precise control of the infusion rate, and drugs that require attention to the emotions of the infused patient.

[0134] The third acquisition unit of the device of this embodiment starts working based on specific trigger conditions. Controlling the monitoring mode of the third acquisition unit according to the drug type improves the effectiveness and timeliness of monitoring. Controlling the opening and closing status of the third acquisition unit by different drug types can reduce the chance of false alarms or false reports. The third acquisition unit does not need to run continuously. The device of this embodiment flexibly adjusts the monitoring strategy of the third acquisition unit according to real-time conditions, thereby improving the pertinence of monitoring activities. Under specific trigger conditions, the data collected by the third acquisition unit is more relevant and practical, which helps to generate accurate historical records and assist in subsequent analysis and decision-making. Turning off the third acquisition unit when monitoring is not required can avoid redundant data collection and make data analysis more accurate. This setting not only optimizes the operating cost of the equipment, but also improves data quality, providing more reliable support for medical services.

[0135] This embodiment comprehensively analyzes the information such as the change in drip rate, activity change, and drug concentration change in the infusion tube during the infusion process of children, so that the device outputs targeted prompt information and / or warning information when the drip rate changes. There are significant differences between the infusion process for children and that for adults, mainly reflected in the fact that children are more susceptible to toxic side effects. For example, some drugs may produce precipitation when combined with other drugs, which may cause serious problems. It may also be necessary to strictly monitor the infusion rate. For example, in the absence of parents or nurses, children adjusting the infusion rate out of curiosity is an inappropriate behavior that requires strict supervision. In addition, some drugs may cause crying during the injection process of children. Such drugs may cause local pain or burning sensation, which may lead to chaos in the infusion room.

[0136] The device of this embodiment is located or integrated in the cabin 100, especially an infusion device for children. The cabin 100 provides an infusion environment for children. The processing unit 400 can be integrated in the cabin 100 and connected to the hospital information system HIS. The processing unit 400 can also be integrated in the computer of the medical side, or the processing unit 400 can be set in a remote computer room and communicate through the signal link of the cabin 100.

[0137] The device comprises a plurality of first collection units, a plurality of second collection units, a plurality of third collection units respectively used for different infusion positions, an output unit 300 corresponding to each patient respectively, and a processing unit 400 for connecting and controlling these units.

[0138] The device of this embodiment can ensure the safety of infusion for children from waiting for puncture, puncture stage to the end of infusion, while improving the comfort of infusion experience. The VR set of the device can serve as the second acquisition unit in the cabin 100, for example, the VR set at the infusion position includes a head-mounted display and a hand motion capture component. Preferably, the VR set at the same infusion position includes two head-mounted displays that can interact with each other. Thus, in the case where the child wears the first head-mounted display, the module of the output unit 300 of the cabin 100 can also be borne by another head-mounted display worn by the family of the child at the same infusion position. Alternatively, the information prompt module can be integrated into the smart terminal of the family of the child in an APP manner, and loaded into another head-mounted display that interacts with the first head-mounted display worn by the child in a virtual reality manner. When the processing unit 400 performs an early warning or prompt related to drug infusion and / or child behavior, the prompt information or early warning information can be displayed by another head-mounted display as an information prompt module. When the prompt information is displayed on another head-mounted display that interacts with the first head-mounted display, family members of the child at the same infusion position will see the prompt window with the current display content paused, and will be required to confirm the operation to eliminate the conditions for generating warnings or prompts related to drug infusion and / or child behavior.

[0139] In this embodiment, in addition to the aforementioned technical solutions, the device may also include a plurality of first acquisition units respectively used for different infusion positions, a plurality of second acquisition units (such as the aforementioned motion capture components), a plurality of third acquisition units, output units 300 corresponding to each patient, and a processing unit 400 for connecting and controlling these units.

[0140] In this embodiment, the medical end may also provide the processing unit 400 with information about the currently infused drug, such as confirming the method of injecting the drug by scanning a QR code. The processing unit 400 loads analysis logic suitable for different types of drugs (such as drugs with precipitation risk, drugs that require precise control of the infusion rate, or drugs that require attention to the emotions of the infused patient) based on the information about the currently infused drug provided by the medical end, and sets the first acquisition unit for each patient according to the information of the current patient and his currently infused drug, so as to monitor drugs with precipitation risk, drugs that require precise control of the infusion rate, or drugs that require attention to the emotions of the infused patient.

[0141] In this embodiment, the processing unit 400 is respectively connected to the first acquisition unit, the second acquisition unit, the third acquisition unit and the output unit 300 by signals, for example, through a wired connection such as Ethernet, SCSI, etc.; a wireless connection such as wireless network technology (Wi-Fi), ZigBee, LoRa, cellular network, etc.; or through a serial device connection converted into an Ethernet signal to achieve remote access.

[0142] The first acquisition unit is configured to monitor the dripping rate of the drug during the infusion process of the child. The first acquisition unit can be a camera, which recognizes the dripping rate during the infusion process through images. The number of cameras installed can be adjusted according to the space size of the cabin 100 and the number of infusion points.

[0143] The second acquisition unit is configured to monitor the activity change information of the child during the infusion process. In this embodiment, the child's activity change information includes body position information such as sitting, lying, standing, walking, squatting, and other behavioral information such as jumping, limb activities, etc. The second acquisition unit can be a body position monitoring belt, which can capture the movement and position changes of the child's body in different postures. The third acquisition unit is configured to monitor the drug deposition or concentration change information in the infusion tube. In pediatrics, the dosage and infusion rate of the drug need to be precisely controlled to ensure the effectiveness and safety of the drug. For example, in pediatric patients, the usual dose of Vancomycin is 10 to 15 mg / kg per kilogram of body weight, administered once every 6 to 8 hours. The concentration range is usually 5 to 10 mg / mL. In order to avoid intravenous irritation or other side effects, the concentration and infusion rate of the drug need to be strictly controlled. The infusion rate of Vancomycin is usually 10 mg / min, that is, 10 mg of the drug is injected per minute. The recommended infusion time is more than 60 minutes, especially at high concentrations, to reduce the risk of adverse reactions. This embodiment stipulates that the functional relationship between concentration and speed is as follows:

[0144] v(t)=C×Q(t),

[0145] The target infusion rate of Vancomycin is v(t) (unit: mg / min), the solution concentration is C (unit: mg / mL), and the infusion rate (volume) is Q(t) (unit: mL / min).

[0146] Here, it is assumed that a 10 kg child needs to be infused with 15 mg / kg of Vancomycin, with a total dose of 150 mg and a drug concentration of 5 mg / mL.

[0147] If the target infusion time is 60 minutes, the total volume of drug is:

[0148]

[0149] To ensure that the infusion is completed within 60 minutes, the volume rate Q(t) is:

[0150]

[0151] The corresponding drug infusion rate is:

[0152] v(t)=5mg / mL×0.5mL / min=2.5mg / min,

[0153] In addition, based on the above relationship, the relationship between the infusion rate and concentration of Vancomycin can be expressed as:

[0154]

[0155] Here, by adjusting the infusion rate Q(t), the concentration C of the drug can be detected and adjusted to ensure a safe infusion rate. This is very important in clinical practice, especially for pediatric patients, to ensure the safety and effectiveness of the drug. If the infusion rate does not match the concentration, it may cause the drug to be infused too quickly or too slowly, causing side effects or poor therapeutic effects.

[0156] In this embodiment, the third acquisition unit may be a camera with depth perception capability. The third acquisition unit may be arranged on the infusion stand in the cabin 100, and a depth perception camera may be installed at a suitable position of the infusion stand to ensure that its monitoring range can cover the entire infusion tube.

[0157] The processing unit 400 is configured to: control the opening and closing state of the third acquisition unit according to the drug dripping rate collected by the first acquisition unit and the activity change information collected by the second acquisition unit, and send reminder information for managing the child's activities to the child's family or send early warning information to medical staff to check the child's status through the output unit 300. When the drug dripping rate exceeds the preset dripping rate range, the third acquisition unit will be activated.

[0158] In this embodiment, the drug dripping rate is set to R d , activity change information is A v , the opening and closing state of the third acquisition unit is S t The state of the output unit 300 sending the prompt information to the family is S h , the status of sending warning information to medical staff is S m . Set the following variables: R min : The lower limit preset value of the drug drip rate; R max : The upper limit preset value of the drug drip rate.

[0159] Specifically, the processing unit 400 is configured to perform the following operations:

[0160] S1 third acquisition unit control logic:

[0161]

[0162] S2 output unit 300 control logic:

[0163] When R d <R min To manage children's activities, send reminders to family members, and / or send warnings to medical staff:

[0164]

[0165] The control logic of the processing unit 400 can be expressed as:

[0166] Control logic = {S t , S h , S m} by R d , A v and its threshold determination.

[0167] During the infusion process, changes in the drug drip rate include slowing down, speeding up, and stopping. Information on changes in children's activities includes changes in body position and other behavioral changes. The third acquisition unit is used to monitor drug deposition or concentration changes in the infusion tube, especially for drugs that are prone to precipitation during infusion.

[0168] For this reason, this embodiment also provides that the third acquisition unit is particularly used to monitor the drug deposition or concentration change in the infusion tube when the drug dripping rate slows down or stops due to changes in the patient's activities. If the infusion rate is too slow, the drug molecules may stay in the infusion tube for a long time, increasing the possibility of deposition.

[0169] The preset drip rate range is the infusion titration rate range of a specific drug that meets medical standards and is prescribed by a doctor's order. The preset drip rate range can also be calculated based on a formula for a set infusion drip rate standard.

[0170] An increase in drug concentration or a decrease in drug concentration refers to a change in the concentration of a specified drug relative to the doctor's order. For example, some drugs have poor in vitro stability and may be dripped too slowly, degrading during the infusion process, ultimately resulting in a decrease in drug concentration. Deposition of drugs in the infusion tube may also lead to changes in local concentrations. During the infusion process, the drug mixes with other solutions, such as saline or glucose solutions, which may affect the final concentration of the drug. For this purpose, the present invention specifically defines as follows:

[0171] ●R(t) represents the change in drip rate at time t, which can be classified into (slow down), (speed up) or R(t)=0 (stop).

[0172] ●A(t) represents the information about the child’s activity changes, including changes in body position and other behavioral changes.

[0173] ●C(t) represents the drug concentration in the infusion tube at time t.

[0174] ●S(t) represents the drug deposition in the infusion tube at time t.

[0175] ●I(t) represents the irritation during drug injection.

[0176] In the dripping rate monitoring method according to this embodiment, the processing unit 400 detects whether R(t) deviates from the preset range [R min ,R max ]. If R(t)<R min or R(t)>R max , triggering further monitoring.

[0177] In the activity monitoring according to this embodiment, the processing unit 400 determines if A(t) leads to Or R(t)=0, the third acquisition unit is activated to monitor the drug deposition S(t) and drug concentration C(t).

[0178] In the concentration change monitoring according to this embodiment, the processing unit 400 monitors any deviation of C(t) from the prescribed concentration C prescribed situation, in which

[0179] C(t)>C prescribed Indicates potential deposition.

[0180] C(t) <C prescribed Indicates possible degradation or dilution.

[0181] In the deposition evaluation according to this embodiment, the processing unit 400 determines when When S(t) is measured, S(t) is evaluated to determine the risk of deposition due to drug molecules staying in the infusion tubing for too long.

[0182] The concentration fluctuation according to this embodiment can be considered the influence caused by mixing with other solutions (such as saline or glucose solution), which is expressed as:

[0183] C(t)=f(C drug , C solution , R(t), T(t))

[0184] Where f is a function that takes into account the interaction between the drug and other solutions and the dilution effect, and T(t) is the time factor that takes into account the change in drug stability over time.

[0185] In the irritation evaluation according to this embodiment, the change of I(t) is evaluated in the following manner, especially the serious irritation problem that may occur during drug injection:

[0186] I(t)=g(C drug , R(t), A(t))

[0187] where g is a function that takes into account the combined effects of drug concentration, drip rate, and children's activities on irritation.

[0188] The following are the specific algorithms for functions f and g:

[0189] Drug concentration fluctuation function f:

[0190]

[0191] Where λ is the degradation rate constant of the drug, R base Is the base drip rate.

[0192] This function indicates that the drug concentration will decay exponentially over time, taking into account the effects of drip rate changes and mixed solutions.

[0193] C drug ·e -λT(t) : Describes the decay of drug concentration over time. The drug may degrade during infusion, and the degradation rate is determined by λ. Exponential decay means that the drug concentration decreases gradually over time.

[0194] Adjust the concentration change to reflect the actual drip rate. base The ratio indicates the change of the current drip rate relative to the reference rate, which affects the actual drug delivery amount.

[0195] Indicates the dilution effect of the mixed solution on the drug concentration. If the drip rate is slowed down, the proportion of the mixed solution increases, resulting in a decrease in drug concentration.

[0196] Stimulus evaluation function g:

[0197]

[0198] Among them, α is the sensitivity coefficient of drug concentration to irritation, β is the influence coefficient of activity change on irritation, and A(t) is the standardized activity change information (such as 0 for no activity and 1 for high activity). Among them:

[0199] α·C drug : Evaluates the basic effect of drug concentration on irritation. The higher the concentration, the stronger the irritation, and α represents the sensitivity of the drug to irritation.

[0200] Reflects the effect of actual drip rate on irritation. An increase in drip rate means that the drug enters the body faster, which may increase irritation.

[0201] (1+β·A(t)): Considers the regulation of stimulation by children’s activities. Increased activity may lead to more stimulation, and β represents the degree of influence of activity on stimulation.

[0202] This function indicates that irritation increases linearly with drug concentration and drip rate, and adjusts for changes in activity. For example, when children are more active (A(t) is higher), irritation increases.

[0203] Specific examples of the application of drug concentration change f:

[0204] Assume that the degradation rate of a drug (such as an antibiotic) is λ = 0.01 (per minute), and the reference drip rate R base =1mL / min, the mixed solution is saline, and its concentration is C solution When the drip rate R(t) = 0.8 mL / min and the time t = 30 min, the drug concentration is:

[0205] C(t)=C drug ·e -0.01·30 0.8+C solution 0.2

[0206] Specific examples of the application of irritation assessment g:

[0207] Assume that the sensitivity coefficient of a drug (such as an antibiotic) is α=2, and the reference drip rate R base =1mL / min, the influence coefficient of activity change on irritation β=0.5.

[0208] At a drip rate of R(t) = 1.2 mL / min and a high activity level in children (assuming A(t) = 1), irritation:

[0209] I(t)=2·C drug 1.2 (1 + 0.5 1)

[0210] I(t)=2·C drug 1.2 1.5

[0211] I(t)=3.6·C drug

[0212] In this way, the concentration changes and irritation of drugs during children's infusion can be described and controlled more accurately, achieving safer and more effective injection management. For example, the following special situations can be considered:

[0213] Drug degradation (increase in λ): When the drug degradation rate is very high, the drug concentration decreases rapidly, and even if the drip rate is normal, the therapeutic effect may be insufficient.

[0214] The drip rate is too low or too high (R(t)<<R base or R(t)>>R base ): Too low: the drug concentration is severely diluted and the effect is reduced; too high: the drug enters the body quickly, increasing the risk of adverse reactions.

[0215] High activity level (A(t) = 1): Increased activity may result in a significant increase in irritation, especially at high drip rates.
