Description

Technical Field

[0001] The present invention relates to the field of infusion care technology, and specifically to an intelligent infusion system and method based on attention transfer, and more particularly to a children's infusion system based on a combination of virtual and real, especially for the injection process management of pediatric chemotherapy, antibiotics or other high-risk drugs. Background Art

[0002] For pediatric injection management, it is necessary to control the injection process of drugs that may precipitate during infusion, such as ceftriaxone, which is commonly used in pediatrics. As a commonly used antibiotic, for example, ceftriaxone sodium and sulbactam sodium for injection is a chemical drug (Ceftriaxone Sodium and Sulbactam Sodium for Injection, C18H18N807S32.0g and C8H11NO5S 1.0g). However, during the infusion of ceftriaxone, special attention should be paid to the precipitation problem, especially when it is mixed with calcium-containing solutions (such as calcium gluconate commonly used in pediatrics). This is because ceftriaxone sodium is an anion and can easily form insoluble precipitates with cationic calcium, causing the drug solution to become turbid. Drug solutions containing precipitates or particles cannot be used for intravenous injection or intravenous drip. Precipitation may cause serious adverse events or even death. In addition, ceftriaxone sodium also has incompatibility with many other drugs.

[0003] For pediatric injection management, some drugs also require control of the infusion rate and / or concentration (concentration can also be expressed as a function of the infusion rate), such as vancomycin, which is commonly used in pediatrics. Although it usually does not cause precipitation problems during infusion, as a glycopeptide antibiotic, vancomycin should be infused slowly in a diluted solution (2.5 to 5.0 mg / mL) for 60 minutes or longer, with a rate not exceeding 10 mg / minute to avoid possible infusion reactions. Methotrexate also requires strict monitoring of the infusion rate. If it is too fast (for example, due to the child's mistaken adjustment of the infusion set), calcium folinate is sometimes needed to be rescued in time to prevent drug toxicity (such as bone marrow suppression, hepatotoxicity, and nephrotoxicity).

[0004] For pediatric injection management, some drugs such as daunorubicin also require attention to children's mood swings while controlling the infusion rate and / or concentration. Although the solution viscosity of daunorubicin is low and it is not easy to deposit during the infusion process, it is highly irritating and the infusion rate needs to be strictly controlled to prevent local reactions. In particular, children have a low tolerance for pain and discomfort, so they may cry because of discomfort when receiving daunorubicin injections. While daunorubicin causes local pain or burning sensations in blood vessels and surrounding tissues, psychological factors also play a role in fueling the situation. This is because children are more sensitive to factors such as hospital environment and needle prickling. Coupled with the discomfort of the drug, it may cause mood swings, manifested as crying, and in severe cases, it may also cause adverse reactions such as nausea and vomiting, which will further cause anxiety among a large number of children in the pediatric infusion room, seriously affecting the work order.

[0005] Methotrexate is an important drug for the treatment of pediatric malignancies, especially in chemotherapy regimens for acute lymphoblastic leukemia (ALL). It is also commonly used to treat certain autoimmune diseases, such as childhood rheumatoid arthritis and psoriasis. Amphotericin B is also used in children with impaired immune function (such as leukemia, during cancer treatment, or after organ transplantation). Especially for children with severe fungal infections, amphotericin B may become the first choice or alternative treatment. However, these two drugs require the use of aluminum foil to wrap the infusion tube, or use light-proof materials to protect the stability of the drugs, especially during long-term infusions of pediatric drugs at a controlled infusion rate. However, the aluminum foil-wrapped infusion tube is likely to cause children to peel it off out of curiosity. Since photosensitive precipitation can affect the efficacy of the drug and even have infusion safety issues, it is necessary to pay attention to the behavior of children during infusion.

[0006] In addition, during the infusion process, the lying or sitting position of the child is also crucial to ensure the consistency and safety of the infusion drip rate, especially when the child receives the infusion in different positions or activities. If the drip rate is uneven and fluctuates frequently during the infusion process, it will cause the drug concentration entering the body to be too high or too low. For example, vancomycin and daunorubicin will be irritating and dangerous. When the infusion rate is too fast, it is easy to cause the blood volume to increase too quickly, thereby increasing the burden on the heart and leading to serious complications such as heart failure and pulmonary edema. Studies have shown that infused drugs will be adsorbed on the infusion set, so the drug concentration will change (Chen Shumin, Peng Zhuxian, Chen Ximin, Pang Yingjie & Chai Xiaoyuan. (2009). Study on regularly shaking the infusion bottle to ensure uniform concentration during intravenous insulin infusion. Hebei Medicine (13), 1675-1676). When the infusion speed is too slow, the drug molecules stay in the infusion tube for a longer time, increasing the possibility of deposition (Wang Xiaoran, Liu Chunli, Wang Ying & Chen Ji. (2017), Audit and management of intravenous drug drip speed based on JCI standards in intravenous drug preparation centers. Chinese Journal of Hospital Pharmacy (23), 2405-2409). Children are more sensitive to drug concentrations. Inappropriate increases in drug concentrations may cause changes in blood biochemistry, phlebitis, and increased stimulation to blood vessels, all of which need to be avoided by precisely controlling the drip rate.

[0007] CN212262052U discloses a remote monitoring device for an infusion pump, including an information acquisition module, an information processing and transmission device, an information display terminal, and a power module. The information acquisition module transmits the collected information to the information processing and transmission device for information processing and transmission to the information display terminal for display, so as to check the working condition of the infusion pump, and the power module provides working voltage for each working module; the information acquisition module includes a drip rate sensor, which is installed on the Murphy-type dropper of the infusion device, and the drip rate sensor is connected to the infusion pump and the information processing and transmission device through a wire, respectively. The information processing and transmission device transmits the drip rate of the infusion pump in each ward and the infusion condition of the medicine bottle to the upper computer through a wireless transmission module, and the medical staff can check the infusion condition of each ward in the office. Although the utility model can monitor the drip rate during infusion, it does not take into account the characteristics of children during infusion, such as the change of drip rate caused by children's hyperactivity and excessive emotions. If the nursing staff needs to check the situation every time the drip rate changes, it will significantly increase their workload.

[0008] CN118105576A discloses an intelligent monitoring infusion method and system, the method includes: determining the fluid replacement reminder data based on the drug dripping data fed back by the monitoring terminal; during the patient's infusion process, determining the abnormal infusion state and the abnormal type according to the infusion speed and the drug liquid strength; sending abnormal reminder data to the preset terminal according to the abnormal type or guiding the patient to adjust the state through the monitoring terminal; when the patient leaves the monitoring area during the infusion process, drawing the patient's movement route and predicting the moving destination according to the monitoring data; predicting the infusion data after the patient leaves the monitoring area according to the patient's disappearance time and the destination attribute, and displaying the fluid replacement reminder data or abnormal reminder data through the preset terminal. Although the invention can intelligently monitor the infusion process, it is also not suitable for monitoring the infusion process of children.

[0009] Unlike adult patients, children are often active and have great mood swings during infusion, and it is difficult for them to maintain the same posture for a long time. They may walk, squat, jump, etc. In some cases, the drip rate will return to normal after the children stop moving; in other cases, the drip rate will change even if the children are not active. The current infusion monitoring method will issue an alarm once it detects an abnormal infusion speed or drip rate, and it is unable to rule out invalid alarms, that is, it is unable to distinguish abnormal situations during the infusion process of children, and therefore it is unable to provide targeted early warning prompts.

[0010] In addition, there are many existing technical solutions for detecting the flow rate in the infusion tube, such as WO2007 / 130868, US6120475A and CN104258487A, all of which adopt non-invasive detection methods.

[0011] 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

[0012] In pediatric intravenous infusion care, it is very important for medical staff to correctly grasp the infusion speed of children. For adult patients without cardiopulmonary diseases, appropriately increasing the infusion speed does not have a significant impact on the patient's cardiopulmonary function. However, for children, their body tolerance, physical characteristics, physiological characteristics, etc. are very different from those of adults. If the infusion speed is too fast, it will cause a sharp increase in circulating blood volume and cause the blood drug concentration to rise too quickly (especially in the process of infusion of some drugs with narrow therapeutic index or large toxic effects, which is very unfavorable to children); and if the infusion speed is too slow, the treatment effect cannot be achieved. Although the children are accompanied by their parents during the infusion, the parents' cognitive level is limited and they cannot accurately judge whether the drip rate is too fast or too slow. Sometimes they will adjust the drip rate by themselves, which is obviously inappropriate. The number of medical staff in the pediatric department is limited and the workload is heavy. Medical staff cannot check on every child at any time. Even if the prior art discloses some infusion monitoring systems, these monitoring systems cannot distinguish whether medical staff are really needed to be present when the drip rate is abnormal during the child's infusion (such as child activities, mood changes, vasospasm, etc.), nor can they distinguish the urgency of the abnormal drip rate. Therefore, the current monitoring system will increase the ineffective work of medical staff, or frequently issue early warning prompts to cause panic among parents.

[0013] In view of the shortcomings of the prior art, the present invention provides an intelligent infusion system based on attention transfer, which may include:

[0014] The VR suit device includes a head-mounted display and a motion capture piece placed on the hands. The VR suit device is used during the puncture stage when children are receiving an infusion, and it distracts children's attention in the form of game interactions.

[0015] The system preferably further comprises a first monitoring unit configured to monitor a drug drip rate during the child's infusion process.

[0016] The system preferably also includes a second monitoring unit, which is configured to monitor activity change information of the child during the infusion process.

[0017] The system preferably further comprises a third monitoring unit configured to monitor information on drug deposition or concentration changes in the infusion tube.

[0018] The system preferably further comprises a reminder unit configured to issue a reminder to the child's family and / or medical staff, and a central processing unit connected to the first monitoring unit, the second monitoring unit, the third monitoring unit and the reminder unit signal respectively, and the central processing unit is configured to:

[0019] After receiving the drug drip rate information "indicating the end of the puncture phase" from the first monitoring unit,

[0020] Based on the current drug dripping rate collected and provided by the first monitoring unit and the activity change information collected and provided by the second monitoring unit, the opening and closing state of the third monitoring unit is controlled, and the reminder unit is controlled to send reminder information to the child's family to manage the child's activities and / or send early warning information to medical staff to check the child's status, wherein the third monitoring unit is controlled to be turned on when the drug dripping rate exceeds the preset dripping rate range.

[0021] The drug drip rate information "characterizing the end of the puncture stage" is determined as follows: starting from a drip rate of zero, after the drip rate reaches a constant during a first time interval and the duration of the constant drip rate itself reaches a second time interval, the first monitoring unit determines the current drug drip rate information "after the duration of the constant drip rate reaches the second time interval" as the drug drip rate information "characterizing the end of the puncture stage".

[0022] To this end, the present invention provides that the central processing unit is configured to selectively control the third monitoring unit to monitor the first drug with a risk of precipitation, the second drug that requires precise control of the infusion speed, and the third drug that requires attention to the emotions of the infused patient. Preferably, during the infusion of the second drug and the third drug, the second monitoring unit selectively collects behavioral information related to the activities of the child at the corresponding infusion position. The first drug is, for example, Ceftriaxone, which may precipitate due to other reasons; the second drug is, for example, Vancomycin and Methotrexate, which may cause infusion reactions; and the third drug is, for example, Daunorubicin, which has a stimulating effect on blood vessels and surrounding tissues, and may cause local pain or burning sensation.

[0023] For the child at the corresponding infusion position, after the central processing unit receives (for example, confirmed or provided by the medical staff) the first drug, the second drug and the third drug, it controls the first monitoring unit to collect and provide the current drug drip rate related to the child at the corresponding infusion position and controls the second monitoring unit to collect and provide activity change information.

[0024] Only when the central processing unit analyzes and confirms that the current drug drip rate and / or activity change information related to the child at the corresponding infusion position reflects that the activity behavior of the child at the corresponding infusion position affects the drug drip rate, the central processing unit controls the opening and closing state of the third monitoring unit, especially turns on the third monitoring unit, and sends reminder information to the child's family to manage the child's activities at the corresponding infusion position and / or sends early warning information to medical staff to check the status of the child at the corresponding infusion position through the reminder unit.

[0025] In particular, when the drug dripping rate exceeds a preset dripping rate range, the third monitoring unit is controlled to be turned on, and in response to the concentration or deposition information provided by the third monitoring unit, the central processing unit selectively provides warning information and / or prompt information related to the drug type related to the child at the corresponding infusion position through the reminder unit.

[0026] The warning information and / or prompt information is provided by the central processing unit via the reminder unit in a manner related to the activity behavior of the child at the corresponding infusion position and / or in a manner related to the first drug with a precipitation risk, the second drug that requires precise control of the infusion rate, or the third drug that requires attention to the emotions of the infused patient.

[0027] In this technical solution, the third monitoring unit is a more expensive device in terms of hardware, and is also software that consumes computing power. Through the above setting of the present invention, it is not necessary to install and use the third monitoring unit for all infusion positions in the space capsule at the same time, but it can be selectively set up specifically for infusion positions with specific action risks and / or specific drug risks. On the one hand, this can greatly reduce the renovation cost of related pediatric outpatient clinics, and on the other hand, it can reduce the frequent alarms at the nurses' station. For a limited number of pediatric nurses, false alarms or unnecessary reminders mean that more patients in need of care may lose the opportunity to be treated, especially during seasonal diseases such as influenza, when limited resources need to be used as much as possible for more critically ill patients.

[0028] It should be noted that the system does not necessarily have to include all of these units to function. On the contrary, the system can completely rely on only one or several of the units to achieve various reasonable functions.

[0029] The hospital environment can easily cause children to feel uneasy. As far as infusion is concerned, children may develop a fear of infusion due to their anticipation of pain, fear of the unknown, or previous unpleasant medical experiences. Usually, when children are receiving infusion, parents or caregivers will restrain them (using physical strength to hold or stabilize the children, or using the hospital's hand fixation device) to prevent them from struggling, but this method will increase the tension, anxiety and fear of the children, and thus cause the children to resist more strongly. The present invention uses VR suit equipment to distract children during the puncture stage, and the head-mounted display provides an immersive environment for children. The motion capture parts placed on the hands allow children to trigger corresponding actions in the game (such as looking left and right with their eyes without moving their limbs, nodding up and down, and raising their heads, etc.) to perform interactive game actions, diverting their attention from the fear and discomfort of the puncture, and finally completing the puncture smoothly.

[0030] The technical solution provides a pediatric infusion system based on a combination of virtual and real, which can ensure smooth execution from the puncture stage to the end of infusion, and further reduce the situation of incorrect evaluation of the subsequent infusion management process due to unsmooth or unsuccessful puncture in the early stage.

[0031] According to a preferred embodiment, the central processing unit is configured as follows: when the drug drip rate is outside the preset drip rate range, and the activity change information reflects that the child changes from a sitting or lying position to a standing, walking, squatting and / or jumping activity state resulting in a redistribution of intravascular pressure, the control reminder unit sends a first reminder message to the child's family to let the child return to the original sitting or lying position.

[0032] According to a preferred embodiment, the central processing unit is configured as follows: after the reminder unit sends a first reminder message to the child's family to let the child return to the original sitting or lying position, if the drug drip rate has not returned to within the preset drip rate range, the control reminder unit sends a first warning message to the medical staff that the child's activities may cause the needle to dislodge.

[0033] Unlike adult patients, children are more active during the infusion process and pay less attention to the puncture site. They may not care about the loosening of the needle at the puncture site when they are active. Children may move more widely during activities, causing the needle to fall out. Even after they stop moving, the drip rate is still abnormal. In this case, medical staff need to check the child to confirm whether the needle is out and whether re-puncture is needed.

[0034] According to a preferred embodiment, the system also includes a timing unit connected to the central processing unit signal, the timing unit is used to time the time period when the drug dripping rate is outside the preset dripping rate range, and the central processing unit is configured to: when the drug dripping rate exceeds the preset dripping rate range and the duration exceeds the first time length, control the third monitoring unit to turn on to obtain drug deposition or concentration change information in the infusion tube.

[0035] According to a preferred embodiment, the central processing unit is configured to: when the drug deposition or concentration change information reflects the occurrence of drug deposition, concentration increase or concentration decrease in the infusion tube, the control reminder unit sends a second warning message to the medical staff that the infusion drug has been deposited or the drug concentration has changed.

[0036] According to a preferred embodiment, the central processing unit is configured to: when the drug dripping rate exceeds the preset dripping rate range, the duration of the drug dripping rate exceeding the limit exceeds the second time length, and the activity change information reflects that the child maintains a sitting or lying position, the control reminder unit sends a second reminder message to the child's family to turn off the infusion device, and at the same time sends a third warning message to the medical staff that the child may have vasospasm during the infusion process; wherein, before sending the third warning message, the central processing unit is also configured to perform the following operations:

[0037] S1) Determination of the state where the drug drip rate is 0: R d =0;

[0038] S2) Determine whether the child is in different activity states Different Activity = A change ∈A states ;

[0039] S3) controlling the reminder unit to send a fourth reminder message for checking the state of the infusion tube when the drug dripping rate is 0 and the child is in different activity states,

[0040] The drug drip rate is R d , the child's activity change information is A change , the set of different activity states is A states .

[0041] When there is no activity change in the child, but the drug drip rate exceeds the preset drip rate range, and the duration of the drug drip rate exceeding the preset drip rate range exceeds the second time length, the third warning message is issued to prompt the medical staff to take corresponding measures. This setting improves the safety of the infusion process, while avoiding frequent issuance of wrong warning messages to interfere with medical staff. Further, before issuing the third warning message, the central processing unit can also judge other situations that occur during the infusion process, such as the situation where the drug drip rate is 0 and the child is in different activity states. In this case, the reason why the drug drip rate exceeds the preset drip rate range may be that the state of the infusion tube caused by the child's own activities changes (the infusion tube is twisted, folded, etc.), and for this situation, the family members of the child can first check and organize the infusion tube by themselves. The central processing unit first excludes the situation that the family members can handle by themselves before issuing the third warning message, which greatly reduces the ineffective work of medical staff.

[0042] Special drugs may be caused by daunorubicin, the third drug of the present invention, which has a stimulating effect on blood vessels and surrounding tissues and may cause local pain or burning sensation. This requires notifying the family members of the child and the medical staff to re-evaluate the type of medication and the consequences of adverse reactions. In addition, other injection conditions can also cause vasospasm, which may affect the distribution of the drug in the body. If the spasm occurs near the infusion site, the drug may not be evenly distributed throughout the body, affecting the therapeutic effect. Vasospasm may cause pain and discomfort, so children may move, adjust their position, or even pull the infusion tube or needle. Frequent changes in body position or self-activity can cause the drip rate of the infusion to be fast and slow, which is more detrimental to the body's absorption of the drug. When vasospasm occurs, medical staff may need to take measures to relieve the spasm, such as using vasodilators or local hot compresses. If the vasospasm is severe, it may be necessary to reselect the vein for puncture because the original puncture site may no longer be suitable for infusion.

[0043] According to a preferred embodiment, when the medical care end confirms before infusion that the drug related to the child at the corresponding infusion position is a first drug with a precipitation risk or a second drug that requires precise control of the infusion speed, the central processing unit generates the second warning information via the second reminder module; or

[0044] When the medical care end confirms before infusion that the drug related to the child at the corresponding infusion position is a third drug that requires attention to the patient's emotions, the central processing unit generates the third warning information via the second reminder module.

[0045] In this technical solution, the adverse effects that different types of drugs may cause during the infusion process are distinguished, and the second reminder module can specifically issue warning information with different meanings. Specifically, the first drug and the second drug may cause precipitation or concentration changes in the infusion drug, and the third drug may cause changes in the patient's mood. The central processing unit can distinguish the adverse effects that may be caused by different drugs and control the second reminder module to specifically issue warning information. On the one hand, it can reduce the probability of false alarms and reduce the ineffective work of medical staff; on the other hand, the difference in warning information allows medical staff to grasp the current situation of the child in advance and ensure the timeliness of intervention measures.

[0046] According to a preferred embodiment, another head mounted display of the VR set device acts as a first reminder module of the reminder unit, which is used to send reminder information to the family members of the child at the corresponding infusion position.

[0047] The benefit of this setting is that another head-mounted display that interacts with the first head-mounted display worn by the child can be used to prompt the child's family. On the one hand, when a situation that requires family members to handle arises during the infusion process, the prompt message can pop up a confirmation button that requires operation confirmation in the form of a prompt window to eliminate the conditions for generating warnings or prompts related to drug infusion and / or child behavior. Family members can interact with the child and keep abreast of possible accidents that may occur in the child. In addition, the child can interact with the parents during the infusion process, so that the child has a more friendly medical experience, and can go through the treatment process more easily, while also helping to reduce the workload of medical staff.

[0048] According to a preferred embodiment, the motion capture component of the VR suit device acts as a second monitoring unit associated with the child at the corresponding infusion position, and the motion capture component provides information about activity changes of the child at the corresponding infusion position to the central processing unit via the VR suit device.

[0049] When the motion capture device is worn on a specific part of the child's body, it can accurately track the child's position and movement. The functions of the motion capture device also include: fixing the body part (such as the hand) of the child for puncture; and having a built-in menu system to allow children to select and set operations in a virtual environment. When the motion capture device is designed as a cartoon shape that children like, the acceptance of the child wearing it is higher, which largely eliminates the fear of the child during the infusion process, and the child can have a good medical experience process. In particular, the design of the motion capture device makes it unnecessary to set up a second monitoring unit in the system of the present invention. In medical institutions with limited budgets, this setting can directly reduce the initial investment and maintenance costs. On the other hand, reducing the monitoring unit can simplify the potential failure points of the overall system, facilitate data collection and processing, avoid data redundancy, and improve data analysis efficiency. According to a preferred embodiment, the central processing unit selectively sets the monitoring mode for controlling the third monitoring unit according to the type of medicine provided by the medical end, wherein the medicine includes a first medicine with a risk of precipitation, a second medicine that requires precise control of the infusion rate, and a third medicine that requires attention to the emotions of the infused patient.

[0050] The third monitoring unit of the present invention starts working based on specific trigger conditions. Controlling the monitoring mode of the third monitoring unit according to the type of drug can improve the effectiveness and timeliness of monitoring. Controlling the on and off state of the third monitoring unit according to the difference in drug types can reduce the probability of false alarms or false reports. Specifically, the first drug has a risk of precipitation, the second drug requires precise control of the infusion rate, and the third drug may affect the patient's mood. For the first drug, it is particularly necessary to monitor its deposition. Drug deposition may lead to a decrease in the concentration of the drug entering the body, thereby affecting the treatment effect; if the deposited drug suddenly enters the body, it will cause the drug concentration in the blood to increase rapidly, which may cause shock or even life-threatening in severe cases.

[0051] The third monitoring unit does not need to run continuously. The system flexibly adjusts the monitoring strategy of the third monitoring unit according to real-time conditions, thereby improving the pertinence of monitoring activities. Under specific trigger conditions, the data collected by the third monitoring 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 monitoring 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.

[0052] According to a preferred embodiment, the second time length is greater than the first time length.

[0053] According to a preferred embodiment, the central processing unit is configured to control the reminder unit to send a third reminder message to the child's family to reduce the infusion rate when the drug drip rate exceeds the upper limit of a preset drip rate range.

[0054] According to a preferred embodiment, the first monitoring unit can also be used to obtain drug information of the infusion.

[0055] According to a preferred embodiment, the central processing unit is configured as follows: when the drug information collected by the first monitoring unit changes, the timing unit starts timing in a third time period, and within the third time period, the first monitoring unit stops collecting the drug dripping rate.

[0056] According to a preferred embodiment, the central processing unit is configured to automatically adjust the preset drip rate range according to the updated drug information to avoid misjudgment of drip rate changes and cause false alarms.

[0057] According to a preferred embodiment, the start time of the third time period is the time when the drug information collected by the first monitoring unit changes.

[0058] According to a preferred embodiment, the end time of the third time period is when the drug input into the puncture site is only the updated drug.

[0059] According to a preferred embodiment, the third time period is the time period during which the updated drug is mixed with the previous drug in the infusion tube and infused into the human body. When the drug is changed, the preset drip rate range is automatically updated to avoid false alarms caused by changes in drip rate under the influence of different drug properties (drug viscosity, solubility, stability and molecular size, etc.).

[0060] Preferably, the first prompt information to the parents can also include: the appropriate range of motion and body position during the infusion process, and how to correctly move and use the mobile infusion stand.

[0061] Technical effects:

[0062] The present invention focuses on the problem that children are more susceptible to toxic side effects, such as Ceftriaxone, which may precipitate due to other reasons. When this drug is combined with other drugs, there is a risk of precipitation causing serious problems; Vancomycin and methotrexate, which may cause infusion reactions, need to be strictly monitored for infusion speed. In the absence of parents or nurses, children's curiosity to adjust the infusion speed is an improper behavior that requires strict supervision; and Daunorubicin, which has a stimulating effect on blood vessels and surrounding tissues and may cause local pain or burning sensation, is one of the reasons why children are prone to crying during injection, which leads to chaos in the infusion room. This is also because children and adults have significant differences in psychology and physiology. In addition, children's blood vessels are smaller than those of adults, their blood vessel walls are thinner, and their tolerance to puncture and stimulation is lower; children's heart volume and blood pumping capacity are smaller than their weight, and children's kidney function is not fully developed, and their ability to clear drugs and liquids is limited; children have strong mobility, etc. During the infusion process, children will not stay still for too long, so the drip rate may change due to their activities. A drip rate that is too fast may cause the heart to be overloaded and cause heart failure; a drip rate that is too slow may cause the drug to settle in the infusion tube or change its concentration, or a drip rate that is too slow may not achieve the drug's effect; a drip rate that varies from fast to slow may cause uneven blood drug concentrations and affect the body's absorption of the drug.

[0063] In order to solve the above problems, the present invention proposes an intelligent infusion system based on attention transfer for the process of children's infusion. By comprehensively analyzing the information such as the change of drip rate, activity change, and drug concentration change in the infusion tube during the process of children's infusion, the system outputs targeted prompt information and / or warning information when the drip rate changes. The present invention can reduce the time for medical staff to patrol the ward on the basis of ensuring the safety of children's infusion process, so that they can manage more patients more efficiently; through targeted warning information, medical staff can respond to abnormal situations in time and reduce the occurrence of medical errors and complications. The present invention can also reduce the psychological pressure of family members. Through the system's automated monitoring and prompts, family members can reduce their continuous concerns about the children's infusion process and reduce the accidental risks caused by inadequate supervision. At the necessary moment, the information-patient feedback provided by the system enables family members to better understand the infusion status of the child, improve their understanding and participation in the treatment process, and enhance the family members' sense of participation.

[0064] The system allows children to maintain appropriate activities during infusion while ensuring infusion safety and improving the overall comfort of children. For drugs that require strict control of the drip rate, such as hypertonic solutions or irritating drugs, the system of the present invention can ensure that the drip rate changes remain within a safe range to avoid damage to the child's blood vessels or body. In addition, the system can provide personalized monitoring and early warning based on the infusion needs and reactions of different children. The system can record and analyze data during the infusion process, providing a basis for continuous improvement of infusion management and child care. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The following is a detailed description with reference to the accompanying drawings.

[0074] 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, such as Ceftriaxone, which may precipitate due to other reasons; Vancomycin and Methotrexate, which may cause infusion reactions; Daunorubicin, which has a stimulating effect on blood vessels and surrounding tissues and may cause local pain or burning sensation. In addition, the difference is also reflected in physiological, psychological and behavioral characteristics. Infusion time is usually longer, and children are usually more active than adults. It is difficult for them to remain still for a long time. Children may feel fear or anxiety during infusion, so their mood swings will be relatively greater during the entire infusion process. In addition, children and adults have different physical tolerance. Some adults feel that the drip rate is too slow and will speed up the drip rate of the infusion by themselves. Under normal circumstances, their bodies can withstand it and will not have obvious reactions; while children's physical tolerance is not as good as that of adults, and there are strict requirements for the dosage and drip rate of their infusion.

[0075] In order to reduce the psychological fear or anxiety of children during the infusion process, existing medical institutions usually provide children with some entertainment or relaxation areas, including dolls and toys for children to relax, and also play some music and videos. Although this design can properly divert the attention of children, during the infusion process, the activities of children will cause changes in the drug drip rate. For example, children may stand, walk, squat or even jump. These activities may cause changes in the pressure in the blood vessels and affect the venous return rate, and ultimately cause the drip rate to become faster or slower. Children's activities lead to an enhanced muscle pump effect, which may indirectly affect the venous return rate. If the blockage in the infusion line is cleared, the drip rate may suddenly increase. For example, when lying down, the pressure in the blood vessels is more evenly distributed, and the drip rate is usually more stable; when sitting, the pressure in the blood vessels is relatively stable, and the drip rate may be similar to that when lying flat; when walking, the muscle activity increases, which may promote blood return; when squatting, the pressure below the heart level increases more significantly, which may cause the drip rate to increase significantly, especially in the veins of the lower limbs. Uneven drip rate during infusion will affect the therapeutic effect of the drug. A dripping rate that is too fast will cause the blood drug concentration to rise too quickly, increasing the burden on the heart; a dripping rate that is too slow will not achieve the therapeutic effect and may even cause the drug to be deposited in the infusion tube. Therefore, the system of this embodiment is especially designed for children to change the dripping rate due to changes in body position or other activities during the infusion process. Although the traditional infusion system can monitor the abnormal situation of the dripping rate change, it cannot distinguish these abnormal situations, resulting in a large number of false alarms and increasing the workload of nursing staff.

[0076] Example 1

[0077] According to this embodiment, the intelligent infusion system based on attention transfer of the present invention is located in or integrated in the space capsule 600. The system is particularly an infusion system for children. The space capsule 600 provides an infusion environment for the children. Figure 4 and Figure 5 The central processing unit 500 can be integrated into the space capsule 600 and connected to the hospital information system HIS. The central processing unit 500 can also be integrated into the computer of the medical staff, or the central processing unit 500 can be set in a remote computer room and communicate via the signal link connection of the space capsule 600, such as Figure 6 shown.

[0078] According to this embodiment, the system includes a plurality of first monitoring units 100, a plurality of second monitoring units 200, a plurality of third monitoring units 300, a reminder unit 400 corresponding to each patient, and a central processing unit 500 for connecting and controlling the above units. Figure 1 and Figure 5 shown. Figure 4 and Figure 5Only one infusion site for one child is shown, but it is conceivable that a plurality of similar or identical infusion sites are provided in the infusion chamber in the form of a capsule 600 .

[0079] According to this embodiment, the pediatric infusion system of the present invention can include existing medical equipment such as infusion pumps, monitors, ventilators, anesthesia machines, etc. Specifically, the system can be used in conjunction with a medical equipment integration module such as Philips IntelliBridge EC10, can be connected to a hospital information system (HIS), transmit relevant data during the infusion process in real time, and support remote monitoring and early warning push.

[0080] In this embodiment, the child infusion system preferably integrates the above hardware into a closed or semi-closed intelligent infusion monitoring system in the form of a space capsule 600. The space capsule 600 has the function of automatic opening and closing. The space capsule 600 integrates a multimedia interactive screen, VR experience equipment, smart toys and dolls. An environmental control system (such as humidity, temperature regulator, etc.) is also designed in the space capsule 600 to create a comfortable and personalized infusion environment for children. The design of the temperature regulator at least provides an infusion environment with a suitable temperature for the child to avoid vasospasm in the child due to too low temperature. In view of the limited space of the space capsule 600, miniaturized and integrated medical equipment is designed to save space and provide efficient medical services. Preferably, an adjustable lighting system is provided in the space capsule 600. In the infusion area, an adjustable lighting design is used, which can be changed according to time, children's emotions and environmental needs. For example, soft blue or green light can bring a sense of tranquility, while bright yellow light can enhance the child's mental state. With the help of an intelligent control system, the brightness and color temperature of the light can be adjusted according to the different stages of the infusion process, helping children better adapt to the treatment process. The colors and patterns inside the Space Capsule 600 can be arranged according to the style that children like.

[0081] Preferably, the capsule 600-type pediatric infusion system includes a first reminder module 410 of the reminder unit 400. The reminder unit 400 may also include a first reminder module 410 for family members disposed in the capsule 600 and a second reminder module 420 for medical staff disposed at the medical end.

[0082] In some cases, although the drip rate has changed abnormally, such as a slow drip rate caused by a twisted infusion tube, this situation does not require a caregiver to come and check, and the family members can do it alone; while in some abnormal situations, such as vasospasm, medical staff need to go to the child for examination. Therefore, the reminder unit 400 of this embodiment includes a first reminder module 410 for issuing reminders to the child's family members, and a second reminder module 420 for issuing reminders to medical staff.

[0083] The first reminder module 410 is disposed in the space capsule 600 and establishes a data connection with the central processing unit 500 of the pediatric infusion system. The first reminder module 410 can be a cartoon-shaped speaker, or a voice playback module integrated into a display screen in the space capsule 600. Preferably, the first reminder module 410 can also be integrated into the smart terminal of the patient's family in the form of an APP.

[0084] The second reminder module 420 can be a smart phone, computer, pager, etc. on the medical staff side. The warning information can be presented in the form of text messages, voice, ringtones, etc.

[0085] Preferably, the space capsule 600 is provided with an intelligent infusion tube blockage alarm device, which can avoid tube blockage caused by the child's hyperactivity, thin blood vessels, etc. during the child's infusion process, and can issue a reminder in time to notify the patient's family or medical staff to deal with it in time.

[0086] Preferably, the system can introduce mechanical devices, such as an infusion pump with a self-regulating function, which can automatically adjust the infusion speed according to the physiological state of the child. At the same time, a comfortable infusion chair is designed, equipped with an adjustable backrest and footrest. When the child is infused, he lies in the infusion chair and wears a VR headset. The screen built into the glasses can play soothing animations or virtual reality scenes to help the child relax. The glasses have a built-in voice assistant, and the child can talk to the device through voice to get comfort and guidance. The assistant will give corresponding psychological support according to the child's emotional changes. The fixator is preferably detachably mounted on the handle of the infusion chair. The fixator can restrain the child's hands, which helps the nurse's puncture process. Preferably, the system is provided with a connecting belt. The connecting belt connects the child's head, upper limbs or hands to restrain the child, which is conducive to the nurse's puncture.

[0087] Example 2

[0088] Based on Example 1, this embodiment further provides a pediatric infusion system, especially a pediatric infusion system based on a combination of virtual and real, such as Figure 1 and Figure 4 This integrated intelligent system can ensure the safety of children's infusion from the waiting stage of puncture to the end of infusion, while improving the comfort of the infusion experience.

[0089] The system includes a VR set 800. According to the present invention, the VR set 800 can act as a second monitoring unit 200 in the space capsule 600. Figure 4 The VR suit 800 at the infusion site includes a head mounted display and a motion capture device worn on the hands.

[0090] Virtual reality (VR) motion capture, used in conjunction with a spatial positioning system at the infusion site, can be used to track the child's hand at the corresponding infusion site. In the wearable glove or grip implementation, the motion capture component may be integrated with a gyroscope (for detecting the rotation and direction change of the holder in space, and providing angular velocity and direction information), an accelerometer (for measuring the linear acceleration of the holder to help determine its moving speed and direction), a magnetometer (for detecting the direction of the holder relative to the geomagnetic field, and providing spatial positioning information), an optical sensor (for receiving light signals emitted by an external tracking device), a camera (for capturing environmental information and assisting in six-degree-of-freedom tracking), a radio frequency sensor (for wireless communication, the holder communicates with an external tracking base station or sensor via RF), a built-in chip (including a microprocessor and / or a microcontroller for processing sensor data, executing algorithms, and communicating with external devices), a sensor fusion algorithm (for fusing data from different sensors to provide more accurate and stable motion capture), a battery, a wireless module (for wireless communication with external devices, such as Wi-Fi, Bluetooth or other proprietary wireless technologies), a tactile feedback motor (a built-in tactile feedback motor can provide vibration feedback to enhance the user experience), a touch sensor (for detecting the user's touch and pressing actions, such as buttons and touchpads), and other modules.

[0091] Preferably, the wearable motion capture device can include a stabilizing plate and a restraint belt. The stabilizing plate is divided into a hand support area and a wrist support area. The hand support area and the wrist support area are integrally connected by a smooth connecting section. The restraint belt includes a palm restraint belt and a wrist restraint belt. At least one end of the restraint belt is detachably connected to the hand support area or the wrist support area, and the restraint belt is connected to the stabilizing plate to stabilize the hand. At the same time, an anti-unlocking component is added to the connection area between the restraint belt and the stabilizing plate to prevent the child from unfastening it by himself. The restraint belt is divided into an anchoring end and a movable end. The anchoring end is fixedly connected to one side of the hand support area or the wrist support area. On the side of the hand support area or the wrist support area away from the anchoring end, a through loop is provided for the restraint belt to pass through. After the movable end of the restraint belt passes through the through loop, it can be turned over and flatly fixed to the surface of the restraint belt to ensure that the fixator stabilizes the child's hand. The setting of the restraint belt can expose the part to be punctured, so that the nurse can perform puncture. The appearance of the holder is preferably designed to be a cartoon shape or other game shape that children are interested in, such as a superhero shield, an airplane model, etc.

[0092] The sensors integrated in the motion capture device can accurately track the position and movement of the child's head, ensuring that the actions in the game are synchronized with the player's actual actions. By identifying the position of the child's head, the motion capture device can trigger the corresponding actions in the game, making the child feel immersive. The head-mounted display and motion capture device are connected to the computer or game console signal. The head-mounted display usually has a built-in menu system that allows the user (child) to select games, settings and scenes in the virtual environment, such as by eye movement. The motion capture device also allows children to use their free arms to play educational games such as chess and cards.

[0093] The VR set (800) is usually used in conjunction with a specific software platform, on which hospital administrators can browse, download and launch games. Sensors and tracking technology within the VR set (800) ensure that the signals of the head-mounted display and the fixture are synchronized to provide a seamless gaming experience.

[0094] According to a preferred embodiment, the picture in the head-mounted display can be synchronized to an external player (such as a display screen in a space capsule). For example, in the display settings of the computer, choose to mirror (copy) or extend the picture of the VR headset to an external player, or use special synchronization software or software provided by the VR system to ensure that the picture in the headset is transmitted to the external player in real time via a wireless network. This setting enables the nurse to see the real-time scene of the child's experience and select the appropriate puncture time point based on the real-time scene. The head-mounted display combines the motion capture of the fixture with the visual and audio effects in the game to enhance the child's sense of immersion, such as giving a reward video after winning a chess and card game.

[0095] In other cases, VR headsets are used to create a fun and interactive game world for children to help them divert their attention and reduce anxiety and discomfort. For example, a series of vivid animated game scenes (fantasy forests, mysterious underwater worlds, or space adventures, etc.) are designed. In these scenes, children can become brave explorers and complete various tasks in the form of intellectual quizzes to earn points and rewards. These points can be used to unlock more game props, characters, or scenes to stimulate their desire for exploration and curiosity.

[0096] For example, in board games that only require small movements of one hand, children can also receive virtual reward medals, which not only symbolize their achievements but also enhance their self-confidence. At the same time, the VR headset will interact with children through encouraging language, such as: "You are so great! Keep working hard, you are almost done", these positive feedback will make them feel supported and valued, and further reduce their tension. The VR headset has a built-in artificial intelligence system that can monitor children's emotional changes in real time, especially when they are crying, AI will recognize these emotions and respond in time. For example, when a child is detected crying, the system will immediately start the comfort mode and gently say to the child: "Baby, what do you like? Let's play together." To enhance the sense of immersion, the VR system can simulate the effect of a camera and provide functions such as mechanical stretching, picture enlargement, focus adjustment and sound adjustment. Children can control elements in the scene with simple gestures, such as enlarging a cute animal, or adjusting the brightness and sound of the picture, allowing them to fully immerse themselves in this virtual world.

[0097] The head-mounted display can be designed as a device similar to glasses or telescopes. The main function of this device is to prevent children from seeing the scene of venipuncture, thereby effectively diverting their attention. The device will be equipped with a high-definition display screen, which can present vivid animation content, such as the adventure story of "Small Head Father" and "Small Head Son" and the story of "Robinson Crusoe". In this story, Small Head Father and Small Head Son will embark on a journey full of fantasy and challenges together to explore the unknown world. Through their language and behavior, children will feel the power of courage and strength, encouraging them to face the upcoming venipuncture. In the animation, Small Head Father will experience various adventures with Small Head Son, such as climbing mountains, crossing foggy forests, and visiting the mysterious underwater world. Whenever faced with difficulties and challenges, Small Head Father will encourage Small Head Son with positive language, such as: "Don't be afraid, son, we can overcome any difficulties together" and "We are going to defeat the virus". These plots can not only inspire children's courage, but also help them understand that facing pain is not terrible, the key lies in a positive attitude and a brave spirit. In addition to animated stories, this device can also be equipped with soothing music and psychological suggestion functions, for example, for 10 minutes. When venipuncture begins, the device will play soft music, such as the natural sound of flowing water, birdsong, waves or other relaxing melodies. At the same time, some positive psychological hints will be displayed on the screen, such as "I am brave" and "I can do it", to help children relieve their inner tension. Parents can participate in this process and guide them to pay attention to the plot in the animation through interaction with their children. Parents can discuss the adventures of Mr. and Mr. with their children, share their own stories of courage, and enhance their children's self-confidence. At the same time, parents can give their children warm encouragement and support to enhance their children's sense of security.

[0098] In other cases, a rich audio and video library is embedded in the head-mounted display, and suitable cartoons and psychological suggestion contents are selected according to the different age stages of children (such as preschoolers and primary school students). For example, for preschoolers, educational interactive stories or game videos can be selected. These cartoons and psychological suggestion contents can be set to play in a loop to ensure that children can maintain their attention and interest even during a long infusion process and reduce their fear of the medical process. Relaxing interludes or interactive links can be added between each video to increase the fun. Multiple selection buttons are set on the edge of the head-mounted display, allowing children to easily select the content they want to watch. The device can adjust the telescopic length and width like a kaleidoscope to adapt to the vision and needs of different children. Through these designs, children can use the device more flexibly and enhance their sense of participation. The head-mounted display is equipped with an intelligent adjustment function that can automatically adjust the brightness according to changes in ambient light to ensure visual comfort. At the same time, the volume can also be adjusted to ensure that it is not too harsh or disturbing to the child's emotions. The clarity adjustment function ensures that children can watch high-definition animation content comfortably. The head-mounted display can intelligently switch modes according to the different states of the child. For example, if a child shows fear, the system will automatically push a relaxing and cheerful animation; if the child is quiet, it can switch to a quieter storyline to help them relax. The flexibility and intelligence of the system enable each child to have a personalized experience.

[0099] Preferably, the VR set (800) at the same infusion position includes two head-mounted displays that can interact with each other. Thus, in the case where the child is wearing a first head-mounted display, the first reminder module 410 of the reminder unit 400 of the space capsule 600 can also be another head-mounted display worn by the family of the child at the same infusion position. Alternatively, the first reminder module 410 integrated into the smart terminal of the family of the child in an APP manner can be loaded in a virtual reality manner on another head-mounted display that interacts with the first head-mounted display worn by the child. When the child wears the first head-mounted display and plays games such as chess and card puzzles in the space capsule 600, the family of the child can jointly execute the game through another head-mounted display that interacts with the first head-mounted display. When the central processing unit 500 executes an early warning or prompt related to drug infusion and / or child behavior, the prompt information or early warning information can be displayed via another head-mounted display that interacts with the first head-mounted display as the first reminder module 410. 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 a confirmation button pop up in the form of a prompt window requiring operation confirmation when the currently displayed content is paused, such as when a jointly executed game is paused, to eliminate the conditions for generating warnings or prompts related to drug infusion and / or child behavior.

[0100] The system's VR set (800) ensures comfort and enthusiasm during venipuncture and infusion. With the help of cartoons, psychological hints and humorous videos suitable for different age groups, children can not only receive treatment imperceptibly, but also enhance their sense of participation and security through interaction with their parents. This innovative treatment method will provide children with a more friendly medical experience, help parents and children get through the treatment process more easily, and also help reduce the workload of medical staff.

[0101] Example 3

[0102] In this embodiment, in addition to the various technical solutions of the aforementioned embodiments, the system of this embodiment may also include a plurality of first monitoring units 100 respectively used for different infusion positions, a plurality of second monitoring units 200 (for example, the motion capture components of the aforementioned embodiments), a plurality of third monitoring units 300, a reminder unit 400 respectively corresponding to each patient, and a central processing unit 500 for connecting and controlling the above units, such as Figure 1 and Figure 6 shown. Figure 4 and Figure 5 Only one infusion position for one child is shown, and it is conceivable that a plurality of similar or identical infusion positions are provided in the infusion chamber.

[0103] In this embodiment, the system can also include a space capsule 600, which provides an infusion environment for the child. Figure 4 and Figure 5 The central processing unit 500 can be integrated into the hospital information system. The central processing unit 500 can also be integrated into the computer of the medical staff. The central processing unit 500 can be set in a remote computer room such as Figure 4 shown.

[0104] In this embodiment, different from Figure 1 and Figure 6 The medical end having only the second reminder module 420 can also provide the central processing unit 500 with information about the currently infused drug, such as confirming the injection method by scanning a QR code. The central processing unit 500 loads the analysis logic suitable for the first drug, the second drug or the third drug according to the information about the currently infused drug provided by the medical end, such as Figure 3 As shown, the first monitoring unit 100 for each patient is set according to the information of the current patient and the currently infused drug, so as to monitor the first drug with precipitation risk, the second drug that requires precise control of the infusion speed, or the third drug that requires attention to the mood of the infused patient.

[0105] In this embodiment, the central processing unit 500 is connected to the first monitoring unit 100, the second monitoring unit 200, the third monitoring unit 300 and the reminder unit 400 by signal, for example, through wired connection such as Ethernet, SCSI, etc.; through wireless connection such as wireless network technology (Wi-Fi), ZigBee, LoRa, cellular network, etc., or through serial device connection converted into Ethernet signal to achieve remote access. After the first monitoring unit 100, the second monitoring unit 200 and the third monitoring unit 300 collect data, they can be processed locally or uploaded to the central processing unit 500 for processing by the central processing unit 500, such as Figure 2 and Figure 3 shown.

[0106] The first monitoring unit 100 is configured to monitor the drip rate of the drug during the infusion process of the child. The first monitoring unit 100 can be a camera, which recognizes the drip rate during the infusion process through an image. The camera is arranged in the space capsule 600. In order to avoid incomplete capture data due to occlusion and other reasons during the infusion process, multiple cameras can be arranged in the space capsule 600, for example, 3 or 4 cameras are installed. The number of cameras installed can be increased or decreased according to the size of the space capsule 600 and the number of infusion points, and there is no restriction here. The cameras can be located directly above the infusion area and on both sides of the infusion area to provide a comprehensive perspective to ensure that there are no blind spots. All cameras can record video data of the infusion process to provide information for medical records and subsequent analysis. Preferably, when the first monitoring unit 100 captures a privacy area involving the child, the system can encrypt the captured privacy data, and the privacy area can use image processing technology, such as blurring or blocking the privacy area, to ensure that only authorized medical staff can access it. The first monitoring unit 100 of this embodiment is a high-resolution camera, such as a CY-ZCH01 USB camera or other medical-grade camera. The first monitoring unit 100 can realize localized image processing by programming, such as using Python's OpenCV library, to read the image of the USB camera and perform image processing tasks, such as edge detection. In addition, the image captured from the camera is saved to a specified folder, which is very useful for recording the dripping situation during the infusion process. The camera usually uses image processing and machine vision technology to collect the dripping rate during the infusion. At least one camera in the first monitoring unit 100 captures images of infusion dripping at a sufficient frame rate; pre-processes the captured images, including adjusting contrast, brightness, denoising, and possible image sharpening to improve the recognizability of droplets in the image; applies an edge detection algorithm (such as a Canny edge detector) to identify droplet boundaries in the image; uses threshold segmentation, contour monitoring and other techniques to locate the position of the droplet; time-marks the image of each droplet to record the exact time when the droplet drips; calculates the dripping rate by analyzing the dripping frequency and time interval of the droplets in the continuous images. For example, if 60 drops of liquid drip per second, the dripping rate can be calculated accordingly; further applies a motion tracking algorithm to track the movement of the droplets in the continuous images to improve the accuracy of the dripping rate measurement; uses a machine learning model to identify and classify different types of dripping rate patterns to improve the ability to recognize changes in dripping rate; integrates the captured image data with the time data to form a detailed record of the infusion dripping rate; transmits the data captured by the camera to the computer or hospital information system at the medical end in real time to facilitate monitoring and management by medical staff, and the collected data can also be used by medical staff to analyze the infusion process and evaluate the treatment effect.

[0107] The second monitoring unit 200 is configured to monitor the activity change information of the child during the infusion process. In the present embodiment, the child's activity change information includes body position change information (such as sitting, lying, standing, walking, squatting, etc.) and other behavioral information (jumping, limb activities, etc.). The second monitoring unit 200 can be a body position monitoring belt. The body position monitoring belt is worn on the child, and has built-in motion and posture sensors to detect the child's body position and activity intensity, and transmit the data to the central processing unit 500. The body position monitoring belt can be worn on the waist, and has built-in multiple sensors, including accelerometers and gyroscopes, and sometimes even muscle electrical activity (EMG) sensors. These sensors work together to capture the movement and position changes of the child's body in different postures. By training the machine learning model, the body position monitoring belt can learn the characteristics of different postures and distinguish various body position changes of children. The body position monitoring belt has real-time data processing capabilities, can quickly analyze sensor data and update the child's body position information in real time. The data collected by the body position monitoring belt can be transmitted to the central processing unit 500 wirelessly, such as Wi-Fi. The body position monitoring belt can not only identify specific postures, but also assess the intensity of children's activities, such as the transition from light activity to vigorous exercise.

[0108] The third monitoring unit 300 is configured to monitor drug deposition or concentration change information in the infusion tube. Even if the drug is transparent, optical flow technology can still analyze the relative movement of pixels in the image sequence to help infer the flow pattern. Taking vancomycin infusion as an example, there is a certain relationship between its speed and concentration. Especially 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 common 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:

[0109] v(t)=C×Q(t)

[0110] 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).

[0111] Here, it is assumed that a 10 kg child requires an infusion of 15 mg / kg of Vancomycin, for a total dose of 150 mg at a drug concentration of 5 mg / mL.

[0112] If the target infusion time is 60 minutes, the total volume of drug is:

[0113] To ensure that the infusion is completed within 60 minutes, the volume rate Q(t) is:

[0114] The corresponding drug infusion rate is: v(t) = 5 mg / mL × 0.5 mL / min = 2.5 mg / min

[0115] In addition, based on the above relationship, the relationship between the infusion rate and concentration of Vancomycin can be expressed as:

[0116]

[0117] 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 treatment effects. For drugs such as methotrexate, if the concentration or dosage is too high (for example, due to a child's mistaken adjustment of the infusion pump), it is sometimes necessary to remind medical staff in the shortest possible time to give calcium folinate for rescue in time to prevent drug toxicity (such as bone marrow suppression, hepatotoxicity and nephrotoxicity).

[0118] Preferably, in this embodiment, the third monitoring unit 300 can be a camera with depth perception capability, such as Intel Real Sense D435i / D455, DF Robot dual-frequency 3D TOF depth camera sensor (model: CS20), Obi Zhongguang Gemini 330 series binocular 3D camera, Phab2 Pro depth camera, etc. The third monitoring unit 300 can be set on the infusion stand 700 in the space capsule 600. The infusion stand 700 uses a retractable rod, allowing medical staff to adjust the height of the infusion stand 700 according to the height of the child or the layout in the space capsule 600. The telescopic rod is designed with multiple adjustment points to meet different height requirements. The base of the infusion stand 700 is equipped with silent rollers, which is convenient for moving in the space capsule 600 and will not disturb the children when moving. The rollers can be locked to ensure that the infusion stand 700 is stable and motionless when in use. A depth perception camera is installed at a suitable position of the infusion stand 700 to ensure that its monitoring surface can cover the entire infusion tube. The position of the depth perception camera is adjustable, and the design allows the depth perception camera to photograph the infusion tube at different angles and distances. The depth perception camera has a built-in microprocessor that analyzes image data through an intelligent algorithm to detect drug deposition or concentration changes. Preferably, the infusion stand 700 is equipped with a touch screen that can display the monitored drug deposition or concentration change information and infusion status, allowing medical staff to view, operate and set. The corners of the infusion stand 700 are rounded to prevent collisions when the child moves in the capsule 600. Preferably, an emergency stop button is provided on the infusion stand 700 to immediately stop the infusion when an abnormality is detected.

[0119] Specific technologies for monitoring drug flow and deposition may include, for example: depth-sensing cameras can observe time-varying flow patterns and possible deposition areas by continuously capturing images and analyzing time series data; highlighting time-varying areas that may reveal drug flow and deposition information through background subtraction techniques; Fourier transforming image sequences to reveal periodic flow patterns or frequency characteristics of deposition; using machine learning models, especially deep learning, trained on large amounts of image data to recognize complex patterns, including the flow and deposition of transparent drugs; applying image enhancement techniques, such as contrast enhancement or edge enhancement, to highlight subtle changes in the flow of transparent drugs. Cameras with depth perception can obtain three-dimensional information on drug flow; conditional random fields (CRFs) can help analyze conditional dependencies in images and distinguish different areas even in the case of high transparency.

[0120] According to a preferred embodiment, the central processing unit 500 is configured to: control the opening and closing state of the third monitoring unit 300 according to the drug dripping rate collected by the first monitoring unit 100 and the activity change information collected by the second monitoring unit 200, and control the reminder unit 400 to send reminder information to the child's family to manage the child's activities and / or send early warning information to medical staff to check the child's status, wherein the third monitoring unit 300 is controlled to be turned on when the drug dripping rate exceeds the preset dripping rate range.

[0121] Assume the drug drip rate is R d , activity change information is A v , the open / closed state of the third monitoring unit 300 is S t The state of the reminder unit 400 sending reminder 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.

[0122] Specifically, the central processing unit 500 is configured to perform the following operations:

[0124]

[0125] S2 reminder unit 400 control logic:

[0126] When R d <R min To manage children's activities, send reminders to family members, and / or send warnings to medical staff:

[0127]

[0128] The control logic of the central processing unit 500 can be expressed as:

[0129] Control logic = {S t， S h , S m} by R d , A v and its threshold determination.

[0130] According to a preferred embodiment, the central processing unit 500 can perform prescribed operations according to the data experience table. Table 1 is an example.

[0131] Table 1

[0132]

[0133] During the infusion process, changes in the drug drip rate include slowing down, speeding up, and stopping. Changes in the child's activities include changes in body position and other behavioral changes. The third monitoring unit 300 is used to monitor drug deposition or concentration changes in the infusion tube. Drug precipitation is especially for ceftriaxone. Once precipitation occurs during injection, it means that a dangerous drug reaction may occur.

[0134] For this reason, the present invention also stipulates that the third monitoring unit 300 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. This is because the infusion rate is too slow, and the drug molecules may stay in the infusion tube for a long time, increasing the possibility of deposition. Some drugs may easily form crystals or precipitation (physical and chemical properties) in the infusion tube due to their physical and chemical properties such as molecular structure, solubility, and stability. When the infusion time is long, the contact time between the drug and the infusion tube increases, increasing the chance of deposition. In particular, high-concentration drug solutions are more likely to form deposits on the tube wall when the dripping rate is slow. If the infusion system is in a static state for a long time, drug molecules may be deposited in the low flow rate area, and the deposited drugs cannot enter the patient's body in time, reducing the treatment effect. Sediments may also become a hotbed for microbial growth, increasing the risk of infection. In addition, in the drug deposition area, the drug concentration is relatively high. If it suddenly enters the body, it may cause adverse reactions due to excessive local concentration.

[0135] According to a preferred embodiment, the central processing unit 500 is configured as follows: when the drug drip rate is outside the preset drip rate range, and the activity change information reflects that the child changes from a sitting or lying position to a standing, walking, squatting and / or jumping activity state resulting in a redistribution of intravascular pressure, the control reminder unit 400 sends a first reminder message to the child's family to let the child return to the original sitting or lying position.

[0136] Assume the drug drip rate is R d , activity change information is A v The state of the reminder unit 400 sending reminder information to the family is S h . 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; A stand : Indicates the state of a child standing; A walk : Indicates the state of children walking; A squat : Indicates the state of a child squatting; A jump : Indicates the state of children jumping; A seated : Indicates the sitting posture of the child; A lying : Indicates the state of a child lying down.

[0137] Specifically, the central processing unit 500 is configured to perform the following operations:

[0138] S1 drug drip rate status judgment:

[0139] Outside Range=(R d <R min )or(R d >R max )

[0140] S2 activity status judgment:

[0141] Activity State = A v ∈{A stand , A walk , A squat , A jump}

[0142] S3 reminder unit 400 control logic:

[0143] When the drug dripping rate is outside the preset range and the activity state reflects the child's activity change, the reminder unit 400 sends a first reminder message:

[0144]

[0145] The control logic of the central processing unit 500 can be expressed as:

[0146] Control logic = S h By R d and A v The state determines

[0147] Among them, S h =1 means sending the first prompt message to let the child return to the original sitting or lying position.

[0148] The preset drip rate range is the infusion titration rate range of a specific drug that meets medical standards as specified by the doctor's order. For example, the drip rate of a 5% glucose solution is specified to be 30 to 40 drops / minute. The drip rate of some chemotherapy drugs such as doxorubicin may be 1 to 2 drops / minute. The preset drip rate range can also be calculated based on the formula for the established infusion drip rate standard.

[0149] According to a preferred embodiment, the central processing unit 500 is configured as follows: after the reminder unit 400 sends a first reminder message to the child's family to let the child return to the original sitting or lying position, if the drug drip rate has not returned to within the preset drip rate range, the control reminder unit 400 sends a first warning message to the medical staff that the child's activities may cause the needle to dislodge.

[0150] Assume the drug drip rate is R dThe state of the reminder unit 400 sending reminder information to the family is S h The state of the reminder unit 400 sending the first warning information to the medical staff is S w . 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; First Alert: Indicates the status of sending the first reminder information to the family to let the child return to the original sitting or lying position.

[0151] Specifically, the central processing unit 500 is configured to perform the following operations:

[0152] S1 drug drip rate recovery status judgment:

[0155] First Alert=S h =1

[0156] S3 warning information status judgment:

[0157] After sending the first prompt message, if the drug dripping rate does not return to the preset range, the control reminder unit sends a first warning message to the medical staff:

[0158]

[0159] Among them, "if First Alert"∧ “Restored” means that the first prompt message has been triggered, but the drug drip rate has not been restored to the preset drip rate range.

[0160] The control logic of the central processing unit 500 can be expressed as:

[0161] Control logic = S w By S h and R d The state determines

[0162] Among them, S w =1 means that the first warning information that the child's activities may cause the needle to be dislodged is sent to medical staff.

[0163] According to a preferred embodiment, the system also includes a timing unit connected to the central processing unit 500 signal, and the timing unit is used to time the time period when the drug dripping rate is outside the preset dripping rate range. The central processing unit 500 is configured to: when the drug dripping rate exceeds the preset dripping rate range and the duration exceeds the first time length, control the third monitoring unit 300 to turn on to obtain drug deposition or concentration change information in the infusion tube.

[0164] Assume the drug drip rate is R d , the duration recorded by the timing unit is T, and the first time length is T threshold_1 , the opening and closing state of the third monitoring unit is S t . Set the following variables: R min : The lower limit preset value of the drug drip rate.

[0165] Specifically, the central processing unit 500 is configured to perform the following operations:

[0166] S1. Judgment of the state where the drug drip rate is lower than the lower limit:

[0167] Under Limit=R d <R min

[0168] S2. Duration judgment:

[0169] Duration Exceeded=T>T threshold_1

[0170] S3. The third monitoring unit 300 controls and determines:

[0171] When the drug dripping rate is lower than the lower limit of the preset range and the duration exceeds the first time length, the third monitoring unit 300 is controlled to start:

[0172]

[0173] The control logic of the central processing unit 500 can be expressed as:

[0174] Control logic = S t By R d and the state of T,

[0175] Among them, S t =1 indicates that the third monitoring unit 300 is turned on to obtain the information of drug deposition or concentration change in the infusion tube.

[0176] According to a preferred embodiment, the central processing unit 500 is configured to: when the drug deposition or concentration change information reflects the occurrence of drug deposition, concentration increase or concentration decrease in the infusion tube, the control reminder unit 400 sends a second warning message to the medical staff that the infusion drug has been deposited or the drug concentration has changed.

[0177] Assume that drug deposition or concentration change information is C v The state of the reminder unit 400 sending the second warning information to the medical staff is S w . Set the following variables: Sediment: indicates the state of drug deposition in the infusion tube; ConcentrationIncrease: indicates the state of drug concentration increase; ConcentrationDecrease: indicates the state of drug concentration decrease.

[0178] Specifically, the central processing unit 500 is configured to perform the following operations:

[0179] S1 Drug deposition or concentration change status judgment:

[0180] Change Detected = C v ∈{Sediment, Concentration Increase, ConcentrationDecrease}

[0181] S2 second warning information control logic:

[0182] When the drug deposition or concentration change information reflects the occurrence of drug deposition, concentration increase or concentration decrease, the control reminder unit sends a second warning message to the medical staff:

[0183]

[0184] The control logic of the central processing unit 500 can be expressed as:

[0185] Control logic = S w By C v The state determines

[0186] Among them, S w =1 means that a second warning message is sent to medical personnel that the infusion drug is deposited or the drug concentration has changed.

[0187] An increase or decrease in drug concentration refers to a change in the concentration of a given drug relative to the order. For example, some drugs have poor in vitro stability and may be infused too slowly, degrading during the infusion process, ultimately resulting in a decrease in drug concentration. Deposition of the drug in the infusion line may also result in a change in local concentration. During the infusion process, the drug is mixed with other solutions, such as saline or glucose solutions, which may affect the final concentration of the drug.

[0188] According to a preferred embodiment, the central processing unit 500 is configured to: when the drug dripping rate exceeds the preset dripping rate range, the duration of the drug dripping rate exceeding the limit exceeds the second time length, and the activity change information reflects that the child remains in a sitting or lying position, the control reminder unit 400 sends a second reminder message to the child's family to turn off the infusion device, and at the same time sends a third warning message to the medical staff that the child may have vasospasm during the infusion process. According to a preferred embodiment, the second time length is greater than the first time length.

[0189] Assume the drug drip rate is R d , the duration is T, the second duration is T threshold_2 , the first time length is T threshold_1 , activity change information is A v The state of the reminder unit 400 sending the third warning information to the medical staff is S w . Set the following variables: R min : The lower limit preset value of the drug drip rate; Sit or Lie means that the child remains in a sitting or lying position.

[0190] Specifically, the central processing unit 500 is configured to perform the following operations:

[0191] S1 drug drip rate is lower than the lower limit of the state judgment:

[0192] Under Limit=R d <R min

[0193] S2 duration judgment:

[0194] Duration Exceeded=T>T threshold_2

[0195] S3 activity change status judgment:

[0196] Activity Valid = A V =Sit or Lie

[0197] S4 second prompt information and third warning information control logic:

[0198] When the drug dripping rate exceeds the preset dripping rate range, the duration exceeds the second time length and the child remains in a sitting or lying position, the control reminder unit sends a second reminder message to the family to turn off the infusion device, and at the same time sends a third warning message to the medical staff that the child may suffer from vasospasm during the infusion process:

[0199]

[0200] S5 time length relationship:

[0201] T threshold_2 >T threshold_1

[0202] The control logic of the central processing unit can be expressed as:

[0203] Control logic = S h and S w By R d , T,A V The state determines

[0204] Among them, S h =1 means sending a second reminder message to the child's family to close the infusion set; S w =1 means that the third warning information is sent to medical staff that vasospasm may occur during the infusion process of children.

[0205] According to a preferred embodiment, the central processing unit 500 is configured to control the reminder unit 400 to send a third reminder message to the child's family to reduce the infusion rate when the drug dripping rate exceeds the upper limit of the preset dripping rate range.

[0206] Assume the drug drip rate is R d , the upper limit of the preset drip rate range is R max The reminder unit 400 sends a third reminder message to the child's family to reduce the infusion rate. The patient's status is S t .

[0207] Specifically, the central processing unit 500 is configured to perform the following operations:

[0208] S1 drug drip rate exceeds the upper limit of the state judgment:

[0209] Above Limit=R d >R max

[0210] S2 third prompt information control logic:

[0211] When the drug dripping rate exceeds the upper limit of the preset dripping rate range, the control reminder unit sends a third reminder message to the child's family to reduce the infusion rate:

[0212]

[0213] The control logic of the central processing unit can be expressed as:

[0214] Control logic = S t By R d The state determines

[0215] Among them, S t =1 indicates that the third reminder message to reduce the infusion rate is sent to the child's family.

[0216] According to a preferred embodiment, the first monitoring unit 100 can also be used to obtain drug information of the infusion. Each time the nurse infuses the child, the infusion bottle or infusion bag containing the drug is displayed with the drug information (drug name, concentration, dosage, etc.) facing the first monitoring unit 100, and the first monitoring unit 100 collects the corresponding drug information.

[0217] According to a preferred embodiment, the central processing unit 500 is configured as follows: when the drug information collected by the first monitoring unit 100 changes, the timing unit counts in the third time period, and the first monitoring unit 100 stops collecting the drug drip rate in the third time period. The benefit of this setting is that after the child's infusion drug or the concentration of the infusion drug changes, the drip rate changes. If the system still uses the preset drip rate range of the previous drug as a reference standard, it will cause a false alarm. The time period when the first monitoring unit 100 stops collecting the drug drip rate can give the system buffer time to call up the preset drip rate range of the new drug.

[0218] Assume that the time when the drug information changes is t change , the length of the third time period T threshold_3 , the state of the timing unit is T c , the drug drip rate collection state of the first monitoring unit is S d .

[0219] Specifically, the central processing unit 500 is configured to perform the following operations:

[0220] S1 Drug information changes:

[0221] t change = Time t causes drug information to change

[0222] The timing of the S2 timing unit in the third time period:

[0223] At the time t when the drug information changes change After that, the timing unit starts timing, and the timing length is: T threshold_3

[0224]

[0225] S3 The first monitoring unit stops collecting the drug drip rate:

[0226] In the third time period, the first monitoring unit stops collecting the drug dripping rate:

[0227]

[0228] The control logic of the central processing unit 500 can be expressed as:

[0229] Control logic = T c and S d By change and the state of t,

[0230] Among them, S d =0 indicates that the first monitoring unit stops collecting the drug dripping rate.

[0231] According to a preferred embodiment, the central processing unit 500 is configured to automatically adjust the preset drip rate range according to the updated drug information to avoid misjudging the drip rate change and causing false alarms.

[0232] Let the updated drug information be I updated , the preset drip rate range is [R min , R max ], the new preset drip rate range is [R min_new , R max_new ], the current drug drip rate is R d , the false alarm state is E b .

[0233] Specifically, the central processing unit 500 is configured to perform the following operations:

[0234] S1 updates the status judgment of the preset drip rate range:

[0235] Adjust the preset drip rate range based on updated medication information:

[0236] [R min_new , R max_new ]=f(I updated )

[0237] Among them, f is a function, which means that according to the drug information I updated Process of updating the drip rate range.

[0238] S2 determines whether the current drug drip rate is within the new range:

[0239] Within New Range=R min_new ≤R d ≤R max_new

[0240] S3 false alarm status judgment:

[0241] When the current drug drip rate is within the updated preset drip rate range, avoid false alarms:

[0242]

[0243] The control logic of the central processing unit 500 can be expressed as:

[0244] Control logic = E b byI updated and R d The state determines

[0245] Among them, E b =0 means no prompt or warning information is issued to avoid false alarms.

[0246] According to a preferred embodiment, the start time of the third time period is the time when the drug information collected by the first monitoring unit 100 changes.

[0247] According to a preferred embodiment, the end time of the third time period is when the drug input into the puncture site is only the updated drug.

[0248] According to a preferred embodiment, the third time period is the time period during which the updated drug is mixed with the previous drug in the infusion tube and is infused into the human body.

[0249] The length of the third time period can be set according to the properties and concentration of the drug, for example, 30s, 45s, 60s, or 120s.

[0250] The advantage of setting the third time period is that when the previous infusion drug is different from the next infusion drug, the updated infusion drug will be mixed with the previous drug remaining in the infusion tube, so the drip rate will change. In this case, the drip rate may become faster or slower. Therefore, the setting of the third time period can avoid false alarms and increase the fear of children and their families; or avoid increasing the ineffective workload of nurses.

[0251] According to a preferred embodiment, the central processing unit 500 is configured as follows: when the drug drip rate is 0 and the activity change information reflects that the child is in different activities, the control reminder unit 400 sends a fourth prompt message to the child's family to check whether the infusion tube is folded or twisted, causing the infusion to be suspended.

[0252] Assume the drug drip rate is R d , the child's activity change information is A change , the set of different activity states is A states The state of controlling the reminding unit 400 to send the fourth reminder information to the child's family is S alert.

[0253] Specifically, the central processing unit 500 is configured to perform the following operations:

[0254] S1 drug drip rate is 0 state judgment:

[0255] Zero Drug Rate = R d =0

[0256] S2 Determination of children’s activity status:

[0257] Determine whether children are in different activity states:

[0258] Different Activity=A change ∈A states

[0259] S3 controls the condition for the reminder unit 400 to issue the fourth reminder information:

[0260] When the drug drip rate is 0 and the child is in different activity states, the control reminder unit sends a fourth reminder message to check the state of the infusion tube:

[0261]

[0262] The control logic of the central processing unit 500 can be expressed as:

[0263] Control logic = S alert By R d and A change The state determines

[0264] Among them, S alert =1 indicates that the fourth reminder message to check the infusion tube is sent to the child's family.

[0265] After receiving the prompt message to check the infusion tube, the family member checks and arranges the infusion tube of the child. If the dripping rate is restored, the reminder unit 400 will not continue to send the prompt message. If the dripping rate is still 0 after the arrangement, or the dripping rate is less than the lower limit of the preset dripping rate range, the central processing unit 500 controls the reminder unit 400 to send the medical staff an early warning message that the child needs to check.

[0266] It should be noted that the above-mentioned specific embodiments are exemplary, and those skilled in the art can combine them or come up with various solutions inspired by the disclosure of the present invention. Those skilled in the art should understand that the present invention specification and its drawings are illustrative and do not constitute a limitation on the claims.
