Description

Technical Field

[0001] The present invention relates to the field of imaging technology, and in particular to an AI-assisted contrast agent leakage early warning analysis device and method. Background Art

[0002] In radiological diagnosis, contrast imaging is the process of taking in substances containing elements with high atomic numbers and then taking radiographs of the pre-diagnosed internal parts for medical diagnosis. Contrast imaging is the process of introducing substances with density inconsistent with that of the body through the digestive tract, respiratory tract, urogenital tract, blood vessels, etc. to the part to be examined, artificially creating a density difference in the examined part, and then using relevant contrast imaging equipment to observe the morphology and function of tissues and organs through this density difference, and finally obtaining a corresponding diagnostic report and conclusion. When performing contrast imaging on patients, contrast agents are needed. Contrast agents are chemicals injected or taken into human tissues or organs to enhance the effect of image observation. The density of these products is higher or lower than that of the surrounding tissues, and the contrast formed is displayed by certain instruments. In contrast injection, a high-pressure syringe is usually used to inject contrast agents into the vein. The contrast agents are generally injected into the patient's body through the peripheral vein at a rate of 1.5-8.0ml / s. During the intravenous injection of contrast agents, extravasation of contrast agents will cause certain stimulation to local tissues, and patients will experience symptoms such as pain and swelling. In severe cases, it can cause local tissue necrosis and even lead to limb dysfunction.

[0003] In the prior art, during the process of intravenous injection of contrast agent to patients, a wristband with multiple pressure sensors is worn to detect the swelling of the arm by pressure detection to detect whether the contrast agent has leaked. This existing method of detecting whether the contrast agent has leaked has at least the following shortcomings: once a leakage occurs when the contrast agent is just injected, it cannot be accurately detected. Only when the contrast agent leaks to a certain extent and causes the arm to swell can it cause pressure changes and be detected. The detection reaction is not sensitive enough. Moreover, when wearing a wristband with multiple pressure sensors, when the patient's arm moves, the local muscle bending and swinging will cause the pressure value detected by the pressure sensor to change, which is prone to false leakage alarms, affecting the normal work of doctors. It can be seen that the existing contrast agent leakage detection method is not accurate enough. To this end, we propose an AI-assisted contrast agent leakage early warning analysis device and method to solve the above problems. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides an AI-assisted contrast agent leakage warning analysis device and method, which can not only accurately determine whether there is leakage when the contrast agent is just injected, but also accurately determine whether there is leakage during the entire injection process, and thus can more accurately analyze and determine whether there is leakage during intravenous contrast agent injection, allowing medical personnel to detect contrast agent leakage early and accurately, which can greatly reduce the occurrence of medical accidents.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an AI-assisted contrast agent leakage warning analysis device, comprising a display, a contrast agent leakage warning analysis mechanism and a high-pressure injector, wherein the contrast agent leakage warning analysis mechanism comprises a bracelet, a main controller, an ultrasonic sensor, a temperature sensor and a pressure sensor, the main controller is fixedly mounted on the outer surface of the bracelet, the ultrasonic sensor, the temperature sensor and the pressure sensor are all fixedly mounted on the inner surface of the bracelet, the ultrasonic sensor is located between the temperature sensor and the pressure sensor, the main controller is electrically connected to the display through a transmission line, and the ultrasonic sensor, the temperature sensor and the pressure sensor are all electrically connected to the main controller.

[0008] Preferably, the inner surface of the bracelet is fixedly connected with a first female Velcro, and the outer surface of the bracelet is fixedly connected with a first child Velcro.

[0009] Preferably, there are multiple ultrasonic sensors, temperature sensors and pressure sensors, and the multiple ultrasonic sensors, multiple temperature sensors and multiple pressure sensors are distributed at equal intervals.

[0010] Preferably, a connecting rope is fixedly connected to the right side of the bracelet, a strap is fixedly connected to the left end of the connecting rope, a second mother Velcro is fixedly connected to the inner surface of the strap, and a second child Velcro is fixedly connected to the outer surface of the strap.

[0011] Preferably, the high-pressure injector comprises a high-pressure syringe, an infusion tube and an intravenous injection needle. The high-pressure syringe is filled with contrast agent, one end of the infusion tube is fixedly connected to the discharge end of the high-pressure syringe, and the intravenous injection needle is fixedly connected to the end of the infusion tube away from the high-pressure syringe.

[0012] Preferably, a control circuit board and a rechargeable battery are fixedly installed in the main controller, the rechargeable battery is electrically connected to the control circuit board, and a charging socket is provided on the right side wall of the main controller, and the charging socket is electrically connected to the rechargeable battery.

[0013] Preferably, a heat dissipation hole is opened on the front inner wall of the main controller, and a dustproof net is fixedly installed in the heat dissipation hole.

[0014] A method for using the above-mentioned AI-assisted contrast agent leakage early warning analysis device includes the following steps:

[0015] S1: First, use the first mother Velcro and the first child Velcro to firmly bind the bracelet to the patient's arm, so that the bracelet is located next to the vein for contrast agent injection, and turn on the display, main controller, ultrasound sensor, temperature sensor and pressure sensor, and then pierce the skin of the patient's arm and insert it into the vein. Then, use the second mother Velcro and the second child Velcro to bind the strap to the patient's arm, wrap the infusion tube and fit it on the skin surface of the patient's arm, and then inject the contrast agent into the vein.

[0016] S2: When contrast agent injection just starts, since the ultrasonic sensor has not formed effective reference data at the beginning of injection, the temperature sensor can be used to monitor the temperature around the arm vein side during intravenous injection of contrast agent in real time, forming a temperature and time curve, which is displayed on the display. When contrast agent injection just starts, contrast agent leakage occurs. Since the vein is located on the surface of the arm, the extravasated contrast agent will cause the skin temperature around the arm to drop, especially near the extravasation point. When the extravasated contrast agent spreads to the temperature sensor, it will be detected by the temperature sensor and cause the temperature curve on the display to change, so that the contrast agent leakage can be accurately and quickly judged. At this time, medical staff should stop injecting contrast agent and make adjustments;

[0017] S3: When the contrast agent injection begins and continues normally, the flow rate of the blood mixed with the contrast agent in the vein is monitored in real time by using an ultrasonic sensor, and the change of the flow rate and time curve is obtained and displayed on the display. The pressure around the arm vein side during the intravenous injection of the contrast agent is monitored in real time by using a pressure sensor, and the change of the pressure and time curve is obtained and displayed on the display. By observing the change of the flow rate curve and the change of the temperature curve and the change of the pressure curve at the same time, it can be more accurately judged whether leakage occurs during the injection of the contrast agent, because after a period of normal injection, the temperature around the intravenous injection body surface will decrease to a certain extent due to the influence of the contrast agent in the vein, and the patient's arm movement and muscle stretching, squeezing and deformation will more or less affect the flow rate curve and the pressure curve. Closely observing and judging the change of the temperature curve, the flow rate curve or the pressure curve is not enough to accurately judge and analyze whether the contrast agent has leaked. Then, by combining the change of the flow rate curve, the observation of the temperature curve and the change of the pressure curve, it can be accurately judged whether the contrast agent injected intravenously has leakage, thereby greatly reducing the occurrence of medical accidents.

[0018] S4: After the intravenous injection of contrast agent is completed, remove the bandage first, then pull out the intravenous needle, and then remove the bracelet.

[0021] (1) The AI-assisted contrast agent leakage warning analysis device and method, by utilizing a contrast agent leakage warning analysis mechanism composed of a wristband, a main controller, an ultrasonic sensor, a temperature sensor and a pressure sensor, and in conjunction with the use of a display and a high-pressure injector, can not only accurately determine whether there is leakage at the beginning of contrast agent injection, but also accurately determine whether there is leakage during the entire injection process, and thus can more accurately analyze and determine whether there is leakage of intravenous contrast agent, allowing medical personnel to detect contrast agent leakage early and accurately, which can greatly reduce the occurrence of medical accidents.

[0022] (2) This AI-assisted contrast agent leakage warning analysis device and method, by using a strap, a second mother Velcro and a second child Velcro together, can tie the infusion tube to the arm during the intravenous injection of contrast agent. When the patient's arm moves, it can effectively prevent the intravenous injection needle from loosening, tilting and falling off, further ensuring the smoothness of the contrast agent injection.

The ultrasonic sensor 4 is located between the temperature sensor 5 and the pressure sensor 6. The main controller 3 is electrically connected to the display 1 through a transmission line 20. The ultrasonic sensor 4, the temperature sensor 5 and the pressure sensor 6 are all electrically connected to the main controller 3. The ultrasonic sensor 4 is used to detect the flow rate of the blood mixed with the contrast agent in the vein in real time, and form a flow rate and time curve, which can be displayed in the display 1. The temperature sensor 5 is used to monitor the temperature around the arm vein side when the contrast agent is injected intravenously, forming a temperature and time curve, which can also be displayed in the display 1. The pressure sensor 6 is used to monitor the intravenous injection of contrast agent in real time. The pressure around the arm vein side during the injection is formed into a pressure-time curve, which can also be displayed on the display 1. A control circuit board 16 and a rechargeable battery 17 are fixedly installed in the main controller 3. The rechargeable battery 17 is electrically connected to the control circuit board 16. A charging socket 18 is provided on the right side wall of the main controller 3. The charging socket 18 is electrically connected to the rechargeable battery 17. The rechargeable battery 17 can be charged by using an external charging line through the charging socket 18. The main controller 3, the ultrasonic sensor 4, and the temperature sensor 4 can be charged by using the rechargeable battery 17. The high-pressure injector comprises a high-pressure syringe 13, an infusion tube 14 and an intravenous injection needle 15. The high-pressure syringe 13 is filled with contrast agent. One end of the infusion tube 14 is fixedly connected to the discharge end of the high-pressure syringe 13. The intravenous injection needle 15 is fixedly connected to the end of the infusion tube 14 away from the high-pressure syringe 13. By using the high-pressure syringe 13, the infusion tube 14 and the intravenous injection needle 15 in combination, the contrast agent can be injected into the patient's vein to facilitate subsequent diagnosis.

[0033] In this embodiment, the inner surface of the bracelet 2 is fixedly connected with a first female Velcro 7, and the outer surface of the bracelet 2 is fixedly connected with a first child Velcro 8. By utilizing the adhesive cooperation of the first female Velcro 7 and the first child Velcro 8, the bracelet 2 can be securely tied to the arm of the patient who needs to inject contrast agent, thereby facilitating the detection of whether there is leakage during the injection process of the contrast agent.

[0034] In this embodiment, there are multiple ultrasonic sensors 4, temperature sensors 5 and pressure sensors 6, and the multiple ultrasonic sensors 4, multiple temperature sensors 5 and multiple pressure sensors 6 are distributed at equal intervals, which can improve the accuracy of arm monitoring results during intravenous injection of contrast agent.

[0035] In this embodiment, a connecting rope 9 is fixedly connected to the right side of the bracelet 2, a strap 10 is fixedly connected to the left end of the connecting rope 9, a second mother Velcro 11 is fixedly connected to the inner surface of the strap 10, and a second child Velcro 12 is fixedly connected to the outer surface of the strap 10. The connecting rope 9 is used to connect the strap 10 and the bracelet 2 together. By utilizing the adhesive cooperation of the second mother Velcro 11 and the second child Velcro 12, the strap 10 can be tied to the arm of the patient who needs to inject contrast agent and is located in front of the bracelet 2. Then, the strap 10 can be used to tie the infusion tube 14 at the front end of the intravenous injection needle 15 to the arm.

[0036] In this embodiment, a heat dissipation hole is opened on the front inner wall of the main controller 3, and a dustproof net 19 is fixedly installed in the heat dissipation hole. The provision of the heat dissipation hole can help dissipate heat inside the main controller 3. The dustproof net 19 can block and intercept external dust to prevent dust from entering the main controller 3.

[0037] In summary, when the AI-assisted contrast agent leakage warning and analysis device provided by the present invention is used, the bracelet 2 is first firmly tied to the patient's arm so that the bracelet 2 is located next to the vein for injecting contrast agent, the display 1, the main controller 3, the ultrasonic sensor 4, the temperature sensor 5 and the pressure sensor 6 are powered on, and then the intravenous needle 15 is inserted into the skin of the patient's arm and inserted into the vein, and then the bandage 10 is tied to the patient's arm, and the infusion tube 14 is wrapped and fits on the surface of the patient's arm skin to reinforce the infusion tube 14, and then the contrast agent can be injected into the vein. When the contrast agent injection is just started, the temperature sensor 5 is used to monitor the temperature around the arm vein side when the contrast agent is injected intravenously in real time, and a temperature and time curve is formed and displayed on the display 1. When the contrast agent is just injected, leakage occurs, and the extravasated contrast agent spreads to When the temperature sensor 5 is at the position where the contrast agent is, it will be detected by the temperature sensor 5 and cause the temperature curve in the display 1 to change, so that the contrast agent leakage can be accurately and quickly determined. When the injection starts normally and the injection continues, the ultrasonic sensor 4 is used to monitor the flow rate of the blood mixed with the contrast agent in the vein in real time, and the change of the flow rate and time curve is obtained and displayed on the display 1. The pressure sensor 6 is used to monitor the pressure around the arm vein side during intravenous injection of the contrast agent in real time, and the change of the pressure and time curve is obtained and displayed on the display 1. By observing the change of the flow rate curve and the change of the temperature curve and the change of the pressure curve at the same time, under the conditions of combining the change of the flow rate curve, the observation of the temperature curve and the change of the pressure curve, it can be more accurately determined whether the contrast agent injected intravenously has leakage, thereby greatly reducing the occurrence of medical accidents.
