Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a bus-based distributed extracorporeal circulation support continuous monitoring device. Background Art

[0002] Extracorporeal circulation, such as extracorporeal membrane oxygenation ECMO, is mainly used to provide continuous extracorporeal respiration and circulation to patients with severe cardiopulmonary failure in order to maintain the patient's life. During ECMO support, doctors generally need to closely monitor the core parameters of the equipment and the patient's blood parameters in order to adjust parameters such as the pump speed of the equipment and prevent complications, thereby improving the level of life support. The parameters that generally need to be focused on are the following: the pump speed of the equipment, the blood flow of the circulation loop, the pump front pressure, the membrane front pressure, the membrane back pressure, the pump pressure difference, the transmembrane pressure difference, the venous oxygen saturation, the arterial oxygen saturation, the hematocrit, the carbon dioxide output, the auxiliary circulation ratio, the circuit bubble alarm, the blood temperature, etc.

[0003] In existing monitoring devices, each sensor is connected to the device using a separate wire, resulting in the need to plug in more than a dozen aviation plugs on the device, which is extremely cumbersome and not portable, and is prone to incorrect connections. In addition, without the critical pump speed information, the various monitored values ​​cannot be effectively analyzed synchronously, and it is impossible to know whether changes in the patient's blood flow, oxygen saturation, etc. are caused by the patient's condition or by changes in the pump speed. In actual clinical use, doctors are required to look up the pump speed information on the duty record sheet and compare it with the monitored data, which increases the workload of medical staff.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0028] The following combination Figures 1-4 The specific structure of the bus-based distributed extracorporeal circulation support continuous monitoring device of the present invention is described.

[0029] like Figure 1 As shown, the bus-based distributed extracorporeal circulation support continuous monitoring device includes a monitoring device body 100 and multiple sensors 300. The monitoring device body 100 is electrically connected to the ECMO device 200. The multiple sensors 300 are arranged on the ECMO consumables pipeline 400. The multiple sensors 300 are connected in series to the first bus 500. The first bus 500 is electrically connected to the monitoring device body 100. The sensor 300 is used to detect the first parameter information of the blood in the ECMO consumables pipeline 400. The monitoring device body 100 is used to obtain the first parameter information and the second parameter information output by the ECMO device 200, and display the first parameter information and the second parameter information.

[0030] It should be noted that the first parameter information includes blood oxygen information or blood flow information. Of course, the specific type of the first parameter information is not limited to this and may also be other parameters. The second parameter information includes pump speed, blood flow, bubble value, and alarm information. Of course, the specific type of the second parameter information is not limited to this and may also be other parameters.

[0031] The bus-based distributed extracorporeal circulation support continuous monitoring device provided by the present invention connects multiple sensors 300 together by using a first bus 500. The sensors 300 are distributed sensor sites, and the number of sensors 300 can be increased or decreased as needed. When connecting, it is only necessary to connect the next sensor 300 to the previous sensor site through a first bus 500, effectively reducing the number of connecting lines, simplifying the circuit structure, and making operation more convenient. In addition, the monitoring device body 100 can obtain the first parameter information and the second parameter information output by the ECMO device 200, and display the first parameter information and the second parameter information. Medical staff can estimate and judge the patient's disease course based on the changing trends of these data. Because information such as pump speed and blood flow can be directly obtained and displayed, it is convenient for doctors to make quick judgments without having to look up information on the ECMO device 200 or paper nursing records, effectively improving the work efficiency of medical staff.

[0032] In addition, this bus-based distributed design has the following benefits: First, it offers high flexibility and scalability. In clinical applications, the specific conditions of different patients and the monitoring needs of doctors may vary. This monitoring device allows medical staff to flexibly adjust the number and type of sensors 300 based on actual needs by simply adding or removing corresponding sensor stations on the first bus 500, eliminating the need for complex rewiring and debugging of the entire monitoring device.

[0033] Second, data synchronization and accuracy are guaranteed. In critical care settings, time is of the essence. This device connects the sensors 300 to the monitoring device body 100 via a first bus 500, ensuring strict synchronization of primary parameter information (such as blood oxygenation and blood flow) and secondary parameter information (such as pump speed, bubble count, and alarm information) during transmission. Medical staff can intuitively observe changes in ECMO system operating parameters and patient blood physiological parameters at the same time. This synchronization provides a reliable basis for accurate clinical decision-making, avoiding misjudgments and treatment delays caused by data asynchrony. This effectively improves response speed to changes in the patient's condition and the targeting of treatment, further enhancing the effectiveness of extracorporeal circulation support therapy.

[0034] Third, system reliability and stability are improved. Traditional monitoring equipment uses numerous independent wires to connect the individual sensors 300, resulting in complex wiring and susceptibility to external electromagnetic interference and other factors, leading to unstable signal transmission and reduced data accuracy. However, the present invention utilizes a first bus 500 for connection, integrating multiple sensors 300 into an efficient and stable communication architecture, enhancing the signal transmission's anti-interference capabilities.

[0035] Fourth, it reduces medical costs and resource waste. From the perspective of medical resource management, the device's simplified circuit structure, reduced number of connecting wires, and improved operational convenience not only reduce the production and maintenance costs of the device itself, but also save hospitals a certain amount of costs in equipment procurement, installation and commissioning, and daily maintenance.

[0036] In one embodiment of the present invention, Figure 2 As shown, the sensor 300 includes a first bus interface 310, a second bus interface 320 and a detection device. The second bus interface 320 and the first bus interface 310 are both electrically connected to the first bus 500. The second bus interface 320 and the first bus interface 310 are electrically connected via the second bus; the detection device is electrically connected to the second bus. Specifically, Figure 2 As shown, the first bus interface 310 is electrically connected to the second bus interface 320 of the previous sensor 300 through a section of the first bus 500, and the second bus interface 320 is electrically connected to the first bus interface 310 of the next sensor 300 through a section of the first bus 500. One end of the second bus is electrically connected to the first bus interface 310, and the other end of the second bus is electrically connected to the second bus interface 320.

[0037] By adopting this connection method, the sensors 300 can be distributed on the bus, which greatly simplifies the wiring structure. Compared with the connection method in which each sensor 300 in the traditional monitoring equipment is independently connected to the monitoring equipment by a wire, the present invention connects multiple sensors 300 in series through a first bus 500, effectively reducing the number of connecting wires, reducing the complexity of line connections, avoiding line confusion and incorrect connection problems caused by a large number of independent wire connections, and improving the reliability and maintainability of the system. At the same time, this connection method is also highly flexible and scalable. In actual applications, medical staff can flexibly increase or decrease the number and type of sensors 300 on the bus according to the specific conditions and monitoring needs of different patients, without the need for complex rewiring and debugging of the entire monitoring system.

[0038] In one embodiment of the present invention, Figure 2As shown, the second bus includes a CAN bus 330 and a DC power bus 340. One end of the CAN bus 330 is electrically connected to the first bus interface 310, and the other end of the CAN bus 330 is electrically connected to the second bus interface 320. One end of the DC power bus 340 is electrically connected to the first bus interface 310, and the other end of the DC power bus 340 is electrically connected to the second bus interface 320. That is, the CAN bus 330 and the DC power bus 340 are both connected in parallel between the first bus interface 310 and the second bus interface 320, thereby electrically connecting the first bus 500 on both sides of the sensor 300 through the first bus interface 310, the second bus interface 320, the CAN bus 330, and the DC power bus 340. By connecting the CAN bus 330 and the DC power bus 340 in parallel between the first bus interface 310 and the second bus interface 320, not only signal transmission between the sensors 300 is achieved, but also a stable power supply is provided for the sensors 300. This arrangement effectively avoids interference caused by the mixing of signal lines and power lines, and improves the stability and accuracy of signal transmission.

[0039] In one embodiment of the present invention, Figure 2 As shown, the detection device includes a power module 350, a sensor probe 360, a signal conditioning and acquisition module 370 and an MCU 380. The power module 350 is electrically connected to the DC power bus 340. The power module 350 is used to draw power from the DC power bus 340, convert the input voltage, and then output the adjusted voltage to the sensor probe 360, the signal conditioning and acquisition module 370 and the MCU 380 to ensure that the above modules work stably.

[0040] The sensor probe 360 ​​is electrically connected to the DC power bus 340 and is used to detect first parameter information of the blood in the ECMO consumables circuit 400. The sensor probe 360 ​​is a blood oxygen saturation probe or a blood flow probe. Of course, the specific type of the sensor probe 360 ​​is not limited thereto and can also be other types of probes. The sensor probe type of each sensor 300 can be the same or different, depending on the specific condition of each patient and the monitoring requirements.

[0041] The signal conditioning and acquisition module 370 is electrically connected to the DC power bus 340 and the sensor probe 360. The signal conditioning and acquisition module 370 is used to collect, filter, amplify, and convert the signals output by the sensor probe 360 ​​into digital signals. Specifically, the sensor probe 360 ​​is used to convert the blood oxygen saturation or blood flow in the ECMO consumables pipeline 400 into an electrical signal. The electrical signal collected by the sensor probe 360 ​​is an analog signal. The signal conditioning and acquisition module 370 first collects the electrical signal output by the sensor probe 360, then filters the collected electrical signal, amplifies the filtered electrical signal, and finally converts the amplified electrical signal into a digital signal and sends it to the MCU 380. The MCU 380 is electrically connected to the DC power bus 340, the signal conditioning and acquisition module 370, the sensor probe 360, and the CAN bus 330. The MCU 380 is used to calculate the digital signal and send the calculated first parameter information to the monitoring device body 100 via the CAN bus 330.

[0042] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the shell includes a main shell 390, which is a rectangular parallelepiped. Of course, the shape of the main shell 390 is not limited to this and can also be other shapes. The main shell 390 is provided with a positioning groove, which forms a notch on one side of the main shell 390. The width of the positioning groove is slightly larger than or equal to the diameter of the ECMO consumables pipeline 400. Such size matching ensures that the ECMO consumables pipeline 400 can be stably clamped in the positioning groove, avoiding measurement errors caused by shaking or displacement of the ECMO consumables pipeline 400 during the detection process. The notch formed on the top of the main shell 390 provides a convenient operating interface for the installation and fixation of the ECMO consumables pipeline 400. Medical staff or equipment maintenance personnel can easily put in or take out the ECMO consumables pipeline 400. At the same time, the design of the notch also facilitates the cleaning or maintenance of the ECMO consumables pipeline 400 and the sensor probe 360 ​​when necessary. The sensor probe 360 ​​is embedded in the side wall of the positioning groove, and the sensor probe 360 ​​faces the ECMO consumable pipeline 400.

[0043] In one embodiment of the present invention, Figure 3 and Figure 4As shown, the housing also includes a cover 391, which is a rectangular plate that fits over the notch. One side of the cover 391 is hingedly connected to the main housing 390, and the other side of the cover 391 is provided with a latch. A latch is provided on one side of the main housing 390, and the latch engages with the latch. Of course, the connection between the cover 391 and the main housing 390 is not limited to this; other connection methods may also be used. The latching connection between the cover 391 and the main housing 390 not only facilitates operation but also ensures that the cover 391 remains stably closed during normal operation of the device, preventing it from loosening or opening due to accidental collisions or device vibrations, thereby protecting internal components from damage. The cover 391 can limit the ECMO consumables tubing 400 in the vertical direction, preventing measurement errors caused by shaking or displacement of the ECMO consumables tubing 400 during testing.

[0044] In one embodiment of the present invention, Figure 5 As shown, the monitoring device body 100 includes a main control circuit board and a display screen. The main control circuit board is electrically connected to the ECMO device 200, and the display screen is electrically connected to the main control circuit board. The display screen is used to display the first parameter information and the second parameter information. The main control circuit board obtains the first parameter information output by the sensor 300 and the second parameter information output by the ECMO device 200 via a first bus 500. The display screen is preferably a touch screen display, and is used to display the first parameter information and the second parameter information.

[0045] The monitoring device body 100 synchronously collects and records the first parameter information and the second parameter information. The display screen displays the patient's blood flow, pressure, blood oxygen saturation and other parameters in the form of tables, curves, etc. for medical staff to conduct comparative analysis. Medical staff no longer need to check the duty records to determine whether the changes in the patient's physiological parameters are caused by the patient's disease course or the change in pump speed.

[0046] The monitoring device body 100 divides the collected and calculated parameters into three categories. The first category is the key parameters obtained from the ECMO device 200 through the communication protocol, such as pump speed, blood flow, bubble alarm, other alarm information and other information; the second category is the parameters collected by the sensor 300 such as pump front pressure, membrane front pressure, membrane back pressure, venous oxygen saturation, arterial oxygen saturation, hematocrit, carbon dioxide excretion, blood temperature, etc.; the third category is the pump pressure difference, transmembrane pressure difference, auxiliary circulation ratio, etc. calculated by formula based on the above parameters. These parameters can be presented to medical staff in various ways such as graphics, curves, data lists, etc.

[0047] The display screen displays data on a consistent timeline, allowing doctors to estimate and assess the patient's course of illness based on these trends. Because information such as pump speed and blood flow is directly captured and displayed, doctors can make their assessments more conveniently and effectively, eliminating the need to consult ECMO equipment or paper nursing records.

[0048] In addition, the monitoring device body 100 can also calculate some calculated values ​​based on the information input by the doctor and the customized formula, according to the real values ​​collected and obtained, such as pump pressure difference (membrane front pressure-pump front pressure), transmembrane pressure difference (membrane front pressure-membrane back pressure), auxiliary circulation ratio (blood flow / theoretical cardiac output) and other information.

[0049] In one embodiment of the present invention, the monitoring device body 100 also includes a quick connector, and the main control circuit board is electrically connected to the ECMO device 200 through the quick connector. The quick connector is an aviation plug. Of course, the specific type of the quick connector is not limited thereto, and it can also be other types of quick connectors. The use of quick connectors significantly improves the connection efficiency and convenience of the detection equipment, reduces the operation time and workload of medical staff during the equipment connection process, and especially in emergency treatment situations, can ensure that the monitoring equipment is put into use in the shortest time, thereby gaining valuable treatment time for the patient. The design of the quick connector also enhances the versatility and compatibility of the equipment, enabling it to adapt to different models of ECMO equipment 200, further expanding the scope of application of the monitoring equipment. In addition, the stability of the quick connector helps to ensure the connection stability of the equipment during use, effectively reduces the risk of data transmission interruption or error due to loose connection, and ensures the continuity and accuracy of the monitoring data.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
