DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0017] Figure 1-Figure 2 Schematic diagram of the structure of an ECMO intelligent operation control system and working method proposed by the present invention; Figure 1 As shown, the ECMO system includes an ECMO monitoring unit, an ECMO control unit, and an ECMO execution unit; the input system includes a patient vital sign parameter unit and a patient treatment demand unit, and the ECMO system provides circulation and respiratory support to the patient; the input system receives the patient's vital sign parameters and treatment requirements, and the patient vital sign parameter unit and the patient treatment demand unit in the input system are input into the ECMO system. The purpose of design scheme and original data recording is achieved.

[0018] The ECMO monitoring unit includes a pressure sensor, a flow sensor, a temperature sensor and a blood oxygen monitor. The ECMO monitoring unit is used to monitor the patient's vital signs, blood oxygen and basic parameters of the device in real time, including blood pressure, temperature, blood oxygen and blood coagulation status, and the pressure and flow of the device.

[0019] The ECMO control unit calculates patient target data and designs treatment plans, controls the ECMO system, and enables automatic operation.

[0020] The ECMO execution unit includes a centrifugal pump, an oxygenator, and an infusion pump. The ECMO execution unit includes executing the ECMO system's treatment of the patient, including regulating the operation of the blood pump, oxygenator, and infusion pump.

[0021] The ECMO monitoring unit continuously monitors basic parameters in real time, especially the ECMO monitoring unit continuously monitors the patient's vital signs, blood oxygen and other parameters in real time.

[0022] The ECMO control unit compares the vital signs monitoring parameters with the target control parameters, generates corresponding control parameters based on the comparison results, and controls the execution unit to adjust the working parameters in real time.

[0023] The patient vital signs parameter unit includes patient temperature monitoring, patient blood pressure monitoring, patient respiratory rate monitoring and patient heart rate monitoring, and the patient treatment demand unit includes patient temperature correction, patient blood pressure correction, patient respiratory rate correction, patient blood volume correction and patient blood oxygen correction.

[0024] Figure 2 It is a flow chart of an ECMO intelligent operation control system and working method, such as Figure 2As shown, an ECMO intelligent operation working method includes the following steps: S1. Medical personnel input the patient's vital sign parameters and treatment requirements into the ECMO system through the vital sign parameter unit and treatment requirement unit in the input system. The ECMO control unit in the ECMO system calculates and designs a treatment plan based on the patient's actual parameters. This includes how the ECMO system adjusts its operating parameters, such as blood flow, oxygen supply, pump speed, etc., to ensure that the patient receives the best treatment effect. At the same time, the control unit will continue to monitor changes in the patient's vital signs and adjust the treatment plan in real time as needed to ensure the continuity and effectiveness of the treatment.

[0025] S2. The ECMO control unit in the ECMO system converts the designed treatment plan into the working parameters of the ECMO execution unit in the ECMO system, and then transmits the working parameters to the corresponding ECMO execution unit. The ECMO execution unit operates according to the actual parameters through the centrifugal pump, oxygenator and infusion pump; The ECMO control unit plays a core role. Once it designs a suitable treatment plan based on the patient's vital signs and treatment needs, and converts the plan into specific working parameters of the ECMO execution unit, the ECMO control unit transmits the precise working parameters to the corresponding ECMO execution unit. After receiving these parameters, the execution unit will immediately start operating according to these actual parameters.

[0026] The centrifugal pump will start to rotate according to the set speed, pushing the blood to circulate in the ECMO system; the oxygenator will inject oxygen into the blood according to the specified oxygen supply to ensure that the blood is fully oxygenated; the infusion pump will deliver necessary fluids into the system according to the set flow rate.

[0027] The ECMO execution unit can operate precisely according to the design of the ECMO control unit, providing patients with stable and effective extracorporeal respiratory and circulatory support. S3. When the ECMO system operates according to the set actual parameters, the ECMO monitoring unit in the ECMO system continuously monitors the actual parameter operation and the patient's vital signs through pressure sensors, flow sensors, temperature sensors and blood oxygen monitors, and transmits the monitoring data to the ECMO control unit.

[0028] Pressure sensor: used to monitor blood pressure in the ECMO system to ensure that it fluctuates within a safe range and to avoid damage to the patient due to excessive or low pressure.

[0029] Flow sensor: Measures blood flow through the ECMO system, a key indicator for evaluating system performance and patient circulation status. Stable flow is critical to maintaining the patient's vital signs.

[0030] Temperature sensor: monitors the temperature of the blood to ensure that it maintains a suitable temperature when entering the patient's body to avoid overheating or overcooling causing adverse effects on the patient.

[0031] Blood oximeter: Real-time measurement of oxygen saturation in the blood, which is an important indicator for evaluating the patient's oxygenation status and the oxygenation effect of the ECMO system.

[0032] In this embodiment, compared with the prior art, the effects of the invention are as follows: In this invention, the patient's vital signs, blood oxygen parameters and treatment requirements are input into the system through the input system, and the control system sets the ECMO system operating parameters according to the internal program, without the need for medical personnel to determine the system operating parameters through empirical judgment; Therefore, the present invention adopts an ECMO intelligent operation control system and working method of the above structure. During the operation of the ECMO system, the monitoring unit will continuously monitor the patient's vital signs and basic parameters of the equipment in real time, and then the control unit will compare the monitoring parameters with the target control parameters, and generate corresponding control parameters based on the comparison results, and control the execution unit in real time to adjust the working parameters. The system has relatively low requirements on the technical level of medical personnel, which is conducive to the popularization of the system and the relief of the work pressure of medical personnel.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
