Obviously, the drawings described below are only some embodiments of the present invention.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] At present, the treatment of cardiovascular diseases faces a series of challenges in drug injection. Traditional cardiovascular drug injection methods often rely on manual operation by medical staff, which has problems such as low precision and large errors. Manual adjustment of injection speed and dosage is difficult to achieve precise control, which may lead to excessive or insufficient drug injection. This may affect the treatment effect for patients with cardiovascular diseases and may even bring risks due to inaccurate drug dosage.

[0036] In addition, traditional cardiovascular drug injection methods often lack effective means to monitor the patient's physiological state in real time. During the injection process, it is impossible to timely understand the changes in the patient's important physiological parameters such as blood pressure, heart rate, blood oxygen saturation, body temperature and respiratory rate, which makes it difficult for medical staff to adjust the treatment plan in time to adapt to the patient's physical condition changes; at the same time, traditional injection systems usually do not have remote monitoring and control functions, which limits the efficient use of medical resources. Doctors cannot understand the treatment situation and make adjustments in time when they are far away from the patients, which is not conducive to the comprehensive management of patients. Moreover, the operating interface of the traditional injection system may not be intuitive and convenient enough, which increases the difficulty of operation and workload of medical staff; further, there is a lack of effective measures to prevent misoperation, which can easily lead to adverse consequences due to misoperation.

[0037] Based on this, the embodiments of the present application provide a cardiovascular assisted injection method and system, which at least solves the problem that the existing cardiovascular drug injection is heavily dependent on manual operation of medical staff, and has the problems of low precision and large errors, thereby achieving the purpose of intelligent, scientific and high-quality injection.

[0038] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0039] First, according to the patient's normal physiological parameters, the drug injection parameters are set and the normal injection is started. Then, as the drug is injected into the patient's body, the patient's physiological parameters are collected in real time. Based on the patient's real-time physiological parameters and the preset patient's normal physiological parameters, the injection speed adjustment value is calculated using a scientific formula, and the injection speed is adjusted according to the injection speed adjustment value. In the above process, the wrong operation signal during the injection process is monitored in real time and the injection is locked at any time. The data generated during the injection process is visualized, safety monitored, and early warning reminders are provided. At the same time, the hospital information management system is connected to remotely monitor and control the injection process.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] In the first aspect, the present application first proposes a cardiovascular auxiliary injection method, see Figure 1 , the method comprising:

[0042] S1. Setting parameters based on human-computer interaction, wherein the parameters include preset normal physiological parameters of the patient and drug injection parameters;

[0043] S2. Start normal injection based on human-computer interaction, and the normal injection speed is the preset injection speed;

[0044] S3, collecting real-time physiological parameters of patients;

[0045] S4, calculating an injection speed adjustment value based on the patient's real-time physiological parameters and preset normal physiological parameters of the patient;

[0046] S5. Adjust the injection speed in real time based on the injection speed adjustment value.

[0047] A cardiovascular auxiliary injection method proposed in this embodiment, by setting parameters through a human-computer interaction interface and collecting various data by sensors for adjusting the injection speed, can flexibly adjust the drug injection amount according to the actual situation of the patient, and can accurately control the speed and dosage of drug injection, reduce the human errors that may be caused by heavy reliance on manual operation of medical staff, ensure that patients receive accurate drug treatment, and improve the treatment effect.

[0048] The following is attached to the instruction manual Figure 1-3 , and steps S1-S5 are used to describe in detail the specific implementation process of the above embodiment.

[0049] S1. Parameter setting is performed based on human-computer interaction, wherein the parameters include preset normal physiological parameters of the patient and drug injection parameters.

[0050] Medical staff will install the cardiovascular auxiliary injection system based on this injection method at the patient's bedside. After starting the cardiovascular auxiliary injection system, the system will first perform parameter initialization and self-test to ensure that each module and sensor is connected normally and in working condition. After the detection system is in a normal state, install the syringe to the injection unit of the system and check whether the injection drug is loaded correctly. Then, the medical staff will set the parameters through the human-computer interaction interface. The parameters mainly include the patient's preset normal blood pressure value, heart rate value, blood oxygen saturation value, body temperature value, respiratory rate value, etc., as well as the parameter settings for drug injection, such as the type of drug, injection speed and dosage, and then prepare for the injection.

[0051] S2. Normal injection is started based on human-computer interaction, and the normal injection speed is the preset injection speed.

[0052] When the injection is ready, the medical staff starts the injection on the human-computer interface, and the system controls the injection unit to inject at the preset injection speed. The injection unit includes a high-precision motor, a precision transmission device, and a syringe. The motor rotates and transmits the power of its output shaft to the syringe through the precision transmission device, thereby accurately controlling the drug injection.

[0053] S3. Collect the patient's real-time physiological parameters.

[0054] As the drug is injected into the patient's body, the patient's physiological parameters may change. At this time, the patient's real-time physiological parameters are collected through the corresponding sensors for further data analysis. Specifically, the real-time physiological parameters collected include the patient's real-time blood pressure, heart rate, blood oxygen saturation, body temperature, and respiratory rate.

[0055] In order to ensure the accuracy of the real-time physiological parameter collection of the patient, preferably, a blood pressure sensor, a heart rate sensor, a blood oxygen saturation sensor, a body temperature sensor, and a respiratory rate sensor are used to collect the above-mentioned real-time physiological parameters of the patient.

[0056] There is no specific limitation on the specific sensor type and model when it is actually selected, as long as it can realize real-time and accurate collection of the above-mentioned physiological parameters of the patient.

[0057] In a preferred embodiment, the blood pressure sensor uses the principle of pressure sensing to measure the blood pressure value by detecting the pressure change in the arterial blood vessels. The heart rate sensor generally uses the method of photoelectric detection or electrocardiogram detection. The photoelectric heart rate sensor calculates the heart rate by emitting light of a specific wavelength to illuminate the skin and detecting the change of the reflected light; while the electrocardiogram heart rate sensor determines the heart rate by detecting the weak electrical signal generated by the electrical activity of the heart. The blood oxygen saturation sensor uses the photoelectric method to calculate the blood oxygen saturation by using the absorption difference of light of different wavelengths when passing through the tissue. When used specifically, it is clamped on the patient's fingers or earlobes, etc., and red light and infrared light are emitted, and the intensity of the reflected light is measured to determine the blood oxygen saturation. The body temperature sensor can be contact or non-contact. Contact sensors, such as thermistor sensors, obtain body temperature values ​​by measuring the temperature of the patient's body surface; non-contact sensors, such as infrared thermometers, estimate body temperature by detecting infrared rays emitted by the human body. The respiratory rate sensor measures the respiratory rate by detecting changes in chest or abdominal movement, or by using an airflow sensor to detect changes in respiratory airflow.

[0058] Blood pressure, heart rate, blood oxygen saturation, body temperature and respiratory rate are all important parameters for evaluating the health status of patients. Comprehensive consideration of these parameters can more accurately determine the patient's condition and treatment effect. This embodiment can comprehensively monitor the patient's physiological state in real time through the multiple sensors set up, providing richer information for cardiovascular disease injection and subsequent treatment.

[0059] S4. Calculate an injection speed adjustment value based on the patient's real-time physiological parameters and preset normal physiological parameters of the patient.

[0060] After the above physiological parameters of the patient are collected in real time, the patient's injection speed adjustment value is calculated according to a preset formula using the patient's real-time physiological parameters and the preset normal physiological parameters of the patient. For example, when the collected patient's blood pressure value suddenly rises, the appropriate injection speed adjustment value will be calculated according to the preset calculation formula, thereby reducing the injection speed to avoid further increase in blood pressure.

[0061] In a preferred embodiment, when calculating the injection speed adjustment value based on the above-mentioned real-time physiological parameters of the patient and the preset normal physiological parameters of the patient, the following formula is used to analyze and process the physiological data and automatically adjust the injection parameters.

[0062] V_adjust=k1×(B-B0)+k2×(H-H0)+k3×(S-S0)+k4×(T-T0)+k5×(R-R0)

[0063] Among them: V_adjust represents the injection speed adjustment value; B is the real-time blood pressure value, B0 is the preset normal blood pressure value; H is the real-time heart rate value, H0 is the preset normal heart rate value; S is the real-time blood oxygen saturation value, S0 is the preset normal blood oxygen saturation value; T is the real-time body temperature value, T0 is the preset normal body temperature value; R is the real-time respiratory rate value, R0 is the preset normal respiratory rate value; k1, k2, k3, k4, k5 are the adjustment coefficients corresponding to indicators such as blood pressure value, heart rate value, blood oxygen saturation, body temperature, respiratory rate, etc. The adjustment coefficients k1, k2, k3, k4, k5, etc. can be determined and optimized based on clinical experience data, a large amount of experimental data, and combined with machine learning and other methods.

[0064] After calculation by the above formula, the injection speed adjustment value V_adjust is obtained. If V_adjust is a positive value, it means that the injection speed needs to be increased; if it is a negative value, it means that the injection speed needs to be reduced. The increase / decrease of the injection speed can be adjusted by referring to the absolute value of V_adjust.

[0065] Different physiological parameters reflect different aspects of the patient's physical condition. The level of the patient's blood pressure directly reflects the strength of the patient's heart contractility. Increased blood pressure indicates that the heart has strong contractility, the stroke volume increases, and the pressure on the blood vessel wall is greater; conversely, decreased blood pressure may indicate weakened heart contractility. In addition, blood oxygen saturation can reflect the patient's cardiovascular status in real time. The heart is responsible for pumping blood to all parts of the body, and smooth blood circulation is the key to ensuring the blood's oxygen-carrying capacity. If there are problems with the cardiovascular system, such as heart failure, congenital heart disease, etc., it will affect the normal circulation of the blood, resulting in insufficient oxygen supply to some tissues and organs, which in turn affects blood oxygen saturation. In addition, the patient's heart rate, body temperature, respiratory rate and other indicators can directly reflect the patient's cardiovascular status.

[0066] The above formula for calculating the injection speed adjustment value can more accurately adjust the injection parameters by comprehensively considering the real-time values ​​and normal values ​​of multiple physiological parameters of the patient, thereby making the injection speed more in line with the actual needs of the patient and improving the accuracy and effectiveness of the treatment. In addition, since each patient's normal physiological values ​​and sensitivity to different parameters may be different, the algorithm can be personalized according to the patient's specific situation.

[0067] S5. Adjust the injection speed in real time based on the injection speed adjustment value.

[0068] After obtaining the adjusted injection speed value, the system sends the injection speed adjustment value to the injection unit, and the injection unit adjusts the injection speed of the drug accordingly according to the injection speed adjustment value. Specifically, the system sends the injection speed adjustment value to the injection unit through an instruction, and then the injection unit adjusts the motor speed and the transmission device action according to the instruction to achieve injection speed adjustment.

[0069] Specifically, by controlling the speed and direction of the motor, the movement speed and direction of the nut can be accurately adjusted, thereby achieving precise control of the injection speed and dosage. The power of the motor is transmitted through the meshing of a series of gears, changing the transmission ratio and the direction of movement, and finally driving the syringe for injection. The speed and accuracy of the injection can be adjusted according to different gear combinations. In specific implementation, it is preferred that it can be flexibly configured according to different application scenarios and requirements, so as to choose to transmit the power of the motor by setting two transmission methods, namely, screw drive or gear drive. Screw drive usually has higher precision and stability, and is suitable for situations where extremely high injection accuracy is required; gear drive may have higher load-bearing capacity and reliability in some cases.

[0070] Preferably, in order to prevent the influence of misoperation on the injection process, Figure 2 As shown, the above steps also include:

[0071] S01. Locking the injection operation based on the monitoring erroneous operation signal.

[0072] In the treatment of cardiovascular diseases, accurate drug dosage and injection speed are crucial. In order to prevent the impact of misoperation on the injection process, the above-mentioned injection unit is provided with an anti-misoperation locking device. The anti-misoperation locking device is usually connected to the control system of the injection unit. Under normal circumstances, when the medical staff performs the correct operation process, the locking device is in an unlocked state, allowing the injection unit to set parameters and operate. For example, when the medical staff sets the injection parameters through the human-computer interaction interface and prepares to start the injection, the system will determine whether the operation complies with the specification. If it does, the locking device will be unlocked to enable the injection unit to work normally; and when the system detects a signal that may be a misoperation, the locking device will immediately start and lock the injection unit to the injection action. Among them, the misoperation signal may include a wrong parameter (such as setting an injection speed that is too high or a wrong drug dosage) setting signal, an unexpected operation action (such as accidentally touching a key button during the injection process) signal, etc. Once these misoperation signals are detected, the locking device will prevent the injection unit from continuing to perform the wrong operation to ensure the safety of drug injection.

[0073] Based on the monitoring of the misoperation signal and locking the injection device based on the misoperation signal, it can effectively avoid the wrong drug injection caused by misoperation and reduce the potential risk of injury to the patient. The anti-misoperation locking device can ensure the accuracy of the injection process and provide additional safety for the patient, especially in a busy medical environment. Medical staff may make operational errors for various reasons. The locking device can prevent serious consequences at critical moments.

[0074] In a more preferred embodiment, Figure 3As shown, the above method also includes:

[0075] S00: Visualize, monitor and provide early warning for the data generated in S1-S5.

[0076] In order to enhance the intelligence and convenience of the above-mentioned cardiovascular assisted injection, the above-mentioned cardiovascular assisted injection method also includes visualizing the data involved in the above-mentioned steps S1-S5, monitoring abnormal data during the injection process and providing early warning reminders.

[0077] Specifically, the human-computer interaction interface is a high-definition touch screen, which is connected to the system controller to display the current injection parameters in real time, such as injection speed, dosage, remaining time, etc., as well as the patient's real-time physiological data obtained from various sensors, such as blood pressure, heart rate, blood oxygen saturation, body temperature and respiratory rate. In addition, medical staff can also set and operate parameters by touching the icons and menus on the screen, such as presetting normal physiological values ​​and drug injection parameters, adjusting injection speed, changing drug dosage, etc. The visual display of the above process through the high-definition touch screen provides an intuitive data display interface and operation interface, allowing medical staff to quickly and accurately obtain and set information, greatly improving the convenience of operation.

[0078] At the same time, during the above process, patient data (including real-time data collected by sensors) is continuously monitored, and an alarm is given through voice prompts when abnormal data appears. If the patient's physiological data is compared with the preset safety range and exceeds the preset range (such as high or low blood pressure, abnormal heart rate, blood oxygen saturation, body temperature and respiratory rate, etc.), an alarm will be immediately sounded through sound and light alarms to remind medical staff to deal with it in time. In addition, the operating status of the injection unit during the above process is monitored. If the injection is abnormal, such as syringe blockage, motor failure, etc., an alarm will be triggered to remind medical staff in time. Medical staff can also check the patient's physiological data and injection progress at any time through the human-computer interaction interface to ensure the safety of treatment.

[0079] When the injection reaches the preset dose or time, the injection unit automatically stops working. The sensor continues to monitor physiological data for a period of time to ensure that the patient's condition is stable. The system records the injection data and stores it for subsequent analysis and research.

[0080] By visualizing, monitoring and warning the data generated in the above process, the accuracy and safety of treatment are improved, the workload of medical staff is reduced, and changes in the patient's condition can be responded to in a timely manner. In addition, the sound and light alarms and prompts of the human-computer interaction interface can allow medical staff to quickly learn of abnormal problems so that they can respond quickly and take appropriate measures to adjust or handle faults, thereby reducing the occurrence of adverse events. In addition, human-computer interaction and alarm reminders can increase the confidence of medical staff and patients in the treatment process. Medical staff know that the system will remind them in time when problems occur, and patients can also experience a safer treatment environment.

[0081] In a more preferred embodiment, Figure 3 As shown, the above method also includes:

[0082] S02, realize remote monitoring and control of S1-S5 based on data interaction.

[0083] During the implementation of the cardiovascular assisted injection method, its corresponding system module can be connected to the hospital information management system to realize data interaction, thereby supporting the remote monitoring and control functions of the system. The cardiovascular assisted injection system establishes communication with the hospital information management system through a network connection, and uploads the collected patient physiological data (such as blood pressure, heart rate, blood oxygen saturation, etc.) and injection parameters (injection speed, dosage, etc.) to the hospital information management system in real time; at the same time, after the hospital information management system passes the authority authentication, it can also send instructions and data to the cardiovascular assisted injection system. For example, authorized doctors can remotely view the patient's treatment status through the information management system at the hospital terminal and adjust the injection parameters as needed. After these instructions are transmitted to the cardiovascular assisted injection system through the network, the system receives and executes these instructions, thereby realizing the remote control function. In addition, the hospital's medical staff can realize remote monitoring through the interface of the information management system, and observe the patient's physiological data changes and injection progress in real time. Through real-time uploaded physiological data, doctors can keep abreast of changes in patients' conditions and make more accurate diagnosis and treatment decisions. For example, when abnormal fluctuations occur in patients' physiological data, doctors can quickly take corresponding measures. Remote monitoring and control functions enable multidisciplinary medical teams to collaborate better and jointly provide patients with better treatment plans. At the same time, it also facilitates experts to conduct remote consultations and guidance on difficult cases.
