[0023] Please refer to Figure 1An embodiment of an extracorporeal circulation monitoring system 100 includes an extracorporeal circulation device 110, a first sensor group 120, a hub device 130, and a monitoring device 140. The first sensor group 120 is connected to the extracorporeal circulation device and is used to detect physiological parameters of the blood circuit of the extracorporeal circulation device 110, such as blood oxygen and temperature. The first sensor group 120 can collect temperature data by contacting the blood circuit of the extracorporeal circulation device 110, or it can collect pressure data by contacting the interior of the blood circuit. The hub device 130 is electrically connected to the first sensor group 120 and also electrically connected to the monitoring device 140. The hub device 130 receives the physiological parameters sent by the first sensor group 120 and sends these physiological parameters to the monitoring device 140. The hub device 130 can be electrically connected to the first sensor group 120 via wire or wirelessly, and it can also be electrically connected to the monitoring device 140 via wire or wirelessly.

[0024] The aforementioned extracorporeal circulation monitoring system 100 includes an extracorporeal circulation device 110, a first sensor group 120, a hub device 130, and a monitoring device 140. The first sensor group 120 is connected to the extracorporeal circulation device 110 and is used to monitor the physiological parameters of the blood circuit of the extracorporeal circulation device 110. The first sensor group 120 is electrically connected to the hub device 130, and the monitoring device 140 is also electrically connected to the hub device 130. The hub device 130 receives the physiological parameters sent by the first sensor group 120 and sends them to the monitoring device 140. Through the hub device 130, the physiological parameters collected by the first sensor group 120 can be sent to the monitoring device 140 in a timely manner. Furthermore, the transmission through the hub device 130 avoids the problem of long distances between the monitoring device and the extracorporeal circulation device, thereby improving the real-time monitoring performance. In addition, the monitoring device 140 and the first sensor group 120 are connected through the hub device 130, making the monitoring device 140 compatible with most CPB and ECMO systems, thus improving compatibility. The hub 130 also has a storage slot, which allows the sensor to be stored when it is not in use, making the structure simple and convenient.

[0025] In one embodiment, the first sensor group 120 includes a pressure sensor, a flow sensor, a bubble sensor, a temperature sensor, and a blood oxygen sensor, all of which are electrically connected to the hub 130. The flow sensor, bubble sensor, temperature sensor, and blood oxygen sensor can contact the outer surface of the blood passage of the extracorporeal circulation device 110 to monitor physiological parameters such as temperature and blood oxygenation. The pressure sensor contacts the fluid in the blood passage of the extracorporeal circulation device 110 to monitor its pressure. Thus, the first sensor group 120 can collect physiological parameters in real time and promptly transmit them to the monitoring device 140 via the hub 130. Furthermore, in one embodiment, the extracorporeal circulation monitoring system further includes a fixing component, which comprises a detachably connected first part and a second part. The pressure sensor includes a pressure sensing element and a pressure sensing area. The pressure sensing element is detachably connected to the blood circuit, and the pressure sensing area is located on the second part. A blood oxygen sensor and a temperature sensor are also located on the second part. When the blood circuit and the second part are connected through the first part, the pressure sensing element abuts against the pressure sensing area, and the blood oxygen sensor and temperature sensor abut against the outer surface of the blood circuit. Specifically, a through-hole is provided in the blood circuit of the extracorporeal circulation monitoring device. The surface of the pressure sensing element near the blood circuit has a protrusion that can pass through the through-hole, thereby contacting the fluid in the blood circuit and enabling real-time pressure monitoring. Because the pressure sensing element abuts against the pressure sensing area, the pressure sensor monitors the pressure and sends the monitored pressure value to the hub device 130. This method makes the connection and disconnection of the first sensor group of the pressure sensor from the blood circuit more convenient.

[0026] Please refer to Figure 2The cable management device 130 has storage slots 131 for storing sensors, such as sensors from the first sensor group, which can be stored in these slots when not in use. The number of storage slots 131 can be the same as the number of sensors in the first sensor group, and they correspond one-to-one, making the structure more compact and avoiding clutter. Furthermore, in one embodiment, a calibration element is provided at the bottom of the storage slots 131 for calibrating the sensors, especially the pulse oximeter sensor. Since the pulse oximeter sensor collects data optically, the calibration element can be a black sheet of paper to calibrate the pulse oximeter sensor and ensure its measurement accuracy. The housing of the cable management device 130 can be made of a waterproof and dustproof material. Additionally, the cables on the cable management device 130 can be flexible spring cables, flexible straight cables, or retractable cables with a housing, allowing the cable management device 130 to meet various distance requirements. It should be noted that the circuitry of the hub 130 can be built into the monitoring device, or the hub 130 can be a separate module, which makes it more convenient to use. The hub 130 is used primarily because the monitoring device is generally far from the extracorporeal circulation equipment. By using the hub 130, the problem of long and numerous connecting cables between the monitoring device and the extracorporeal circulation equipment can be avoided. The hub 130 allows the sensor cables on the extracorporeal circulation equipment to be directly connected to the hub 130 with a very short cable, while a single cable 132 from the hub 130 connects to the monitoring device 140, avoiding the clutter and other problems caused by multiple connections between the monitoring device and the extracorporeal circulation equipment.

[0027] Additionally, please refer to... Figure 2 The hub 130 has multiple ports 133 for electrical connection to sensors in the first sensor group. It should be noted that there is no one-to-one correspondence between the sensors in the first sensor group and ports 133. When a sensor in the first sensor group is connected to a port 133, the hub can automatically identify the sensor model. This design greatly improves the flexibility of cable management for medical personnel and shortens the startup time of the entire system setup. Furthermore, both the hub 130 and the monitoring device 140 are equipped with clamping devices, allowing them to be fixed to medical slide rails or medical rods for quick locking and unlocking.

[0028] As described above, the monitoring device in this extracorporeal circulation monitoring system is compatible with most CPB and ECMO systems. When the monitoring device is compatible with CPB, in one embodiment, the extracorporeal circulation monitoring system further includes a first gas flow sensor, a first carbon dioxide sensor, and an oxygen sensor. These sensors are all electrically connected to the monitoring device. The first gas flow sensor monitors the airflow of the input gas, while the first carbon dioxide sensor and oxygen sensor monitor the carbon dioxide and oxygen content in the gas in the input gas pipeline, respectively. Further, the first gas flow sensor, first carbon dioxide sensor, and oxygen sensor can be electrically connected to the monitoring device via a control device (such as an MCU). In one embodiment, the first gas flow sensor, first carbon dioxide sensor, and oxygen sensor are all located on the monitoring device; that is, they can be located on the back of the monitoring device, i.e., the side opposite the screen. This arrangement makes the entire system structure more compact.

[0029] In another embodiment, when the monitoring device is compatible with ECMO, the extracorporeal circulation monitoring system further includes a first gas flow sensor, a first carbon dioxide sensor, an oxygen sensor, a second airflow sensor, and a second carbon dioxide sensor. The first gas flow sensor, the first carbon dioxide sensor, and the oxygen sensor are all electrically connected to the monitoring device; the second airflow sensor and the second carbon dioxide sensor are respectively electrically connected to a hub. Specifically, the first gas flow sensor monitors the airflow of the input gas, and the first carbon dioxide sensor and the oxygen sensor monitor the carbon dioxide and oxygen content in the gas in the input gas pipeline, respectively. Further, the first gas flow sensor, the first carbon dioxide sensor, and the oxygen sensor can be electrically connected to the monitoring device via a control device (such as an MCU). In one embodiment, the first gas flow sensor, the first carbon dioxide sensor, and the oxygen sensor are all located on the monitoring device; that is, the first gas flow sensor, the first carbon dioxide sensor, and the oxygen sensor can be located on the back of the monitoring device, i.e., the side opposite the screen. This arrangement makes the entire system structure more compact.

[0030] In addition, the second airflow sensor and the second carbon dioxide sensor are used to measure the flow rate of the gas input to the human body and the corresponding carbon dioxide content, respectively. The second airflow sensor and the second carbon dioxide sensor can also be electrically connected to a hub via a control device (such as an MCU). In one embodiment, the extracorporeal circulation monitoring system further includes a support and a trolley, with the first sensor group mounted on the support and the second airflow sensor and the second carbon dioxide sensor mounted on the trolley, thus making the overall system structure more compact.

[0031] In one embodiment, all sensors mentioned in any of the above embodiments are labeled, such as each sensor in the first sensor group, the first gas flow sensor, the first carbon dioxide sensor, the oxygen sensor, the second airflow sensor, and the second carbon dioxide sensor, which can help doctors identify them in complex tangled cables. The label can be a tag or a color layer.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
