[0064] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0065] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0066] Please refer to Figure 1 , Figure 1 This is a flow chart of an injection method for a nuclear medicine automatic injection device in some embodiments of the present application. The injection method for a nuclear medicine automatic injection device is used in a terminal device and includes the following steps:

[0067] S101, testing the syringe based on the debugging parameters, generating a test result, and calibrating the syringe based on the test result to obtain a calibrated syringe;

[0068] S102, matching the corresponding radiopharmaceutical based on the patient's nuclear medicine examination and treatment purpose;

[0069] S103, assessing the patient's physical condition based on the patient's basic information and determining an appropriate dose of radiopharmaceuticals for the patient;

[0070] S104, setting injection parameters based on the operation interface, establishing an intravenous channel, controlling the syringe to inject the radioactive drug based on the injection parameters, and monitoring radiation status information in real time;

[0071] S105: Monitor the radiation level based on the radiation status information, and send a radiation alarm according to the radiation level.

[0072] It's important to note that the parameters that need to be set on the nuclear medicine automated injection system's interface typically include drug dosage, injection rate, and injection time. The drug dosage is determined based on the patient's weight, age, condition, and specific examination or treatment requirements; the injection rate takes into account factors such as the nature of the drug, the patient's vascular condition, and tolerance; and the injection time is related to the drug dosage and injection rate. Proper settings ensure that the drug is accurately and safely delivered to the patient.

[0073] After the injection, the patient is required to remain in an observation area for a period of time, typically 30 minutes to an hour, so that medical staff can monitor the patient for any adverse reactions. This includes monitoring the patient's vital signs, such as temperature, pulse, respiration, and blood pressure, as well as any discomfort symptoms such as headache, nausea, vomiting, or rash. The injection site is also monitored for any delayed swelling, pain, or other abnormalities.

[0074] If a patient experiences an adverse reaction during the observation period, medical staff will promptly implement appropriate emergency measures based on the specific circumstances. For minor adverse reactions, such as mild dizziness or nausea, the patient can be kept quiet and given appropriate comfort and symptomatic treatment, such as drinking an appropriate amount of water and practicing deep breathing. For severe adverse reactions, such as anaphylactic shock or severe arrhythmia, emergency procedures will be immediately initiated, including cardiopulmonary resuscitation and anti-allergic treatment. Experts from relevant departments will be promptly notified for consultation and further treatment.

[0075] Please refer to Figure 2 , Figure 2 This is a flow chart of a syringe calibration method for an injection method of a nuclear medicine automatic injection device in some embodiments of the present application. According to an embodiment of the present invention, the syringe is tested based on the debugging parameters, the test results are generated, and the syringe is calibrated based on the test results to obtain a calibrated syringe, specifically including:

[0076] S201, check whether the various components of the syringe are working properly, whether the power supply is stable, and whether the various connection parts are loose or leaking;

[0077] S202, setting various parameters on the control interface of the automatic injector according to the patient's condition and injection requirements, including injection dose, injection speed and injection time;

[0078] S203, injecting a set amount of simulated drug or normal saline, and checking whether the injection dose and injection speed of the syringe meet the set injection condition information;

[0079] S204, if the set injection condition information is met, it is determined that the injection meets the test requirements and a test result is generated;

[0080] S205: If the set condition information is not met, deviation data is generated, and parameter calibration and component inspection and maintenance of the syringe are performed based on the deviation data.

[0081] It's important to note that various parameters, such as injection dose, injection rate, and injection time, are set on the automatic injection device's control interface based on the patient's condition and injection requirements. These parameters are typically adjusted based on the type of radiopharmaceutical, the patient's vascular condition, and the specific needs of the examination or treatment. For example, a slower injection rate may be required for some highly irritating radiopharmaceuticals to reduce vascular irritation.

[0082] Check that all components of the automated injection device are functioning properly, including the microinjection pump, push mechanism, sensor, and display. Ensure that the device's power supply is stable and that all connections are not loose or leaking. Also, check the device's radiation protection, such as the integrity of the lead glass protective sleeve and shielding, to ensure the safety of medical staff and patients.

[0083] Before formal use, calibrate and test the automatic injection device. By injecting a certain amount of simulated medication or saline, check the device's metering accuracy and injection speed stability. If any errors or abnormalities are found, make timely adjustments and repairs to ensure accurate and reliable drug delivery.

[0084] Please refer to Figure 3 , Figure 3 This is a flow chart for selecting radiopharmaceuticals for a nuclear medicine automatic injection device in some embodiments of the present application. According to an embodiment of the present invention, matching the corresponding radiopharmaceuticals based on the patient's nuclear medicine examination and treatment objectives specifically includes:

[0085] S301, obtaining the patient's medical records, and analyzing the patient's treatment plan and treatment goals based on the patient's medical records;

[0086] S302, establishing corresponding medical examination items based on the patient's treatment plan and treatment goals;

[0087] S303, screening radioactive drugs based on different medical examination items and analyzing the matching degree;

[0088] S304, determining whether the matching degree is greater than or equal to a set matching degree threshold;

[0089] S305: If it is greater than or equal to, select the current radioactive drug; if it is less than, reselect the radioactive drug.

[0090] It should be noted that the corresponding radioactive drug is selected by analyzing the patient's treatment plan to ensure that the radioactive drug is consistent with the patient's physical condition and treatment objectives.

[0091] According to an embodiment of the present invention, the patient's physical condition is assessed based on the patient's basic information to determine the appropriate dose of radiopharmaceuticals for the patient, specifically including:

[0092] Obtain the patient's basic information, including age, gender, weight, height, medical history, and allergy history;

[0093] Perform a comprehensive physical examination on the patient and obtain the examination results, including examination items such as cardiopulmonary function, liver and kidney function;

[0094] Evaluate the dose range of radioactive drug injections that patients should receive during nuclear medicine examinations or treatments based on the examination results;

[0095] The required dose of radioactive drug is calculated based on the patient's examination items, basic information of the patient and specific requirements of the examination or treatment. The required dose of radioactive drug is within the dose range of radioactive drug injection.

[0096] According to an embodiment of the present invention, injection parameters are set based on an operation interface, an intravenous channel is established, a syringe is controlled based on the injection parameters to inject the radioactive drug, and radiation status information is monitored in real time, specifically including:

[0097] Establish intravenous access between the patient and the syringe using a needle;

[0098] Based on the patient's basic information and specific requirements for examination or treatment, set the injection parameters on the operation interface. The injection parameters include drug dosage, injection speed and injection pressure;

[0099] The radioactive drug is injected based on the injection parameters of the syringe, and the radiation dose rate and radionuclide distribution information of the radioactive drug are collected in real time based on the radiation monitoring equipment to obtain radiation status information;

[0100] The radiation status information is transmitted to the operation interface in real time for display and processing.

[0101] It should be noted that the syringe containing the radioactive drug is installed in the automatic injection device and the syringe and injection tube are connected tightly and leak-free. At the same time, the relevant parameters of the syringe, such as the syringe stroke and piston movement speed, are calibrated and set according to the injection parameters set on the operation interface to ensure that the drug can be accurately delivered according to the preset dosage and speed.

[0102] After the automatic injection program is activated, the injection device drives the syringe's piston according to the set parameters, injecting the radiopharmaceutical into the patient's vein at a constant rate. During the injection process, the operator should closely observe the patient's reactions, such as any discomfort symptoms such as pain, dizziness, and nausea, as well as any abnormalities at the injection site, such as swelling or leakage. The operator should also monitor the operating status of the injection device to ensure proper operation. If any abnormality is detected, the injection should be stopped immediately and appropriate measures should be taken.

[0103] According to an embodiment of the present invention, monitoring the radiation level based on the radiation status information and sending a radiation alarm according to the radiation level specifically includes:

[0104] Acquire radiation status information, compare the radiation status information with the set radiation standard, and obtain the radiation level;

[0105] Set a radiation alarm threshold and determine whether the radiation level is greater than or equal to the set radiation alarm threshold;

[0106] If it is greater than or equal to, a warning message is generated and a radiation alert is sent based on the warning message;

[0107] If it is less than, it is determined that the radiation level is within a safe range.

[0108] It should be noted that during automated nuclear medicine injections, specialized radiation monitoring equipment, such as portable radiation dose rate meters and radionuclide imaging devices, is typically used to monitor radiation status in real time. These devices can be placed at key locations such as the injection site, around patients, and in radiopharmaceutical storage and handling areas to comprehensively and accurately monitor radiation levels.

[0109] Radiation monitoring equipment collects real-time information such as radiation dose rate and radionuclide distribution, and transmits this information to a central control system or user interface for display and processing. This information is analyzed to determine whether it exceeds preset safety thresholds and the trend of radiation dose changes. If an abnormal radiation status is detected, the system immediately issues an alarm, prompting the operator to take appropriate measures.

[0110] Radiation status information is automatically recorded, creating detailed monitoring data files. This data is crucial for assessing radiation safety, tracing the use of radiopharmaceuticals, and conducting quality control. Data records should include detailed information such as monitoring time, location, radiation dose rate, radionuclide type, and activity. These records must be stored long-term in accordance with relevant regulations for future reference and analysis.

[0116] The radiation level is monitored based on the radiation status information, and a radiation alarm is sent according to the radiation level.

[0117] It's important to note that the parameters that need to be set on the nuclear medicine automated injection system's interface typically include drug dosage, injection rate, and injection time. The drug dosage is determined based on the patient's weight, age, condition, and specific examination or treatment requirements; the injection rate takes into account factors such as the nature of the drug, the patient's vascular condition, and tolerance; and the injection time is related to the drug dosage and injection rate.
