Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a physiological sign monitoring method and monitoring equipment for fluid infusion. Background Art

[0002] When doctors are rehydrating patients, they often measure the patient's central venous pressure (CVP) to determine whether the patient has volume responsiveness and the risk of volume overload. CVP refers to the pressure in the right atrium and the thoracic segment of the superior and inferior vena cava. It can determine the comprehensive situation of the patient's blood volume, cardiac function and vascular tension, which is different from peripheral venous pressure.

[0003] Currently in clinical practice, monitors can only provide real-time measurement of CVP parameters. When rehydrating, doctors need to find CVP waveform data from a variety of parameter waveform information on the main monitoring interface of the monitor, and subjectively judge the changes in CVP during rehydration based on their own experience to decide whether to continue or stop rehydration, which is very inconvenient.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] The CVP2-5 principle is a commonly used judgment principle in clinical practice, that is, if 100-200 ml of fluid is quickly replenished within 10 minutes and the CVP increases by less than 2 mmHg, it indicates that the patient is volume responsive and fluid replenishment can continue. When the CVP increases between 2-5 mmHg, fluid replenishment needs to be suspended to observe whether CVP can recover. When the CVP increases by more than 5 mmHg, it indicates that the patient is at risk of volume overload and fluid replenishment should be stopped.

[0027] The following is a detailed description of the physiological sign monitoring method for fluid replacement in the present invention. It should be noted that the monitoring equipment mentioned in the present invention is not limited to monitors, but also includes invasive / non-invasive ventilators, anesthesia machines, defibrillators, nurse stations, central stations, etc. with monitoring functions.

[0028] See also Figure 1 , Figure 1 The flowchart of the physiological sign monitoring method for fluid infusion in this embodiment includes:

[0029] Step 101: Acquire central venous pressure monitoring data of a monitored subject during fluid infusion.

[0030] In this embodiment, the monitoring device can obtain the acquisition signal of the central venous pressure of the monitored object under fluid infusion through a measuring device connected to the human body. The monitoring device can convert the acquisition signal of the central venous pressure of the monitored object under fluid infusion into an electrical signal, and perform preprocessing such as interference suppression, signal filtering and amplification, and finally obtain the central venous pressure monitoring data of the monitored object under fluid infusion.

[0031] Central venous pressure is the pressure at the point where the superior and inferior vena cava enter the right atrium. It is measured through a catheter placed in the superior and inferior vena cava or right atrium. It reflects the right atrial pressure and is one of the main indicators for clinical observation of hemodynamics. In clinical practice, it is usually used as an indicator of fluid infusion rate and amount.

[0032] Step 102: Generate central venous pressure trend information based on central venous pressure monitoring data.

[0033] In this embodiment, after the monitoring device obtains the central venous pressure data of the monitored object under fluid infusion through a measuring device connected to the human body, since the central venous pressure monitoring data of the monitored object under fluid infusion usually changes continuously with the passage of time, the monitoring device can store the central venous pressure monitoring data of the monitored object under fluid infusion obtained within a preset time period, so as to obtain the central venous pressure trend information of the monitored object.

[0034] It should be noted that the central venous pressure trend information can display the monitoring data of the central venous pressure within a preset time period (eg, 30 minutes). Of course, it can also be set according to actual conditions, and there is no specific limitation.

[0035] Step 103: Display a dedicated tool interface for fluid replenishment in the main monitoring interface.

[0036] In this embodiment, the monitoring device may provide a main monitoring interface, and generate a special tool interface for displaying the fluid replenishment status of the monitored object on the main monitoring interface.

[0037] Usually, the main monitoring interface of conventional monitoring equipment will display various conventional physiological sign waveform information. Medical staff need to find the CVP data that needs attention from the complex information, so that medical staff cannot intuitively and efficiently obtain the data information they want to pay attention to when judging the fluid replenishment situation. In this embodiment, when medical staff need to pay attention to CVP data information, a fluid replenishment situation special tool interface is displayed in the main monitoring interface, and medical staff can intuitively obtain the desired CVP data information by observing the special tool interface. Specifically, the fluid replenishment situation special tool interface can pop up from the main monitoring interface after the user touches the CVP tool icon on the main monitoring interface.

[0038] For example, see Figure 2 , Figure 2 It is a hemodynamic monitoring interface for monitoring equipment. Figure 3 This is a schematic diagram of a dedicated tool interface for fluid infusion in an embodiment of the present application, wherein the user's operation instructions can be received on the hemodynamic monitoring interface, that is, the operation instructions for the 201 area "CVP 2-5 tool", and the following is generated and displayed: Figure 3 The dedicated tool interface for fluid replenishment is shown.

[0039] It can be understood that the dedicated tool interface for fluid replenishment can be a display area embedded in the main monitoring interface, or it can be suspended on the main monitoring interface; the dedicated tool interface for fluid replenishment may cover or not cover other content displayed on the main monitoring interface.

[0040] Step 104: Display central venous pressure trend information in the dedicated tool interface for fluid infusion.

[0041] In this embodiment, after the monitoring device displays the dedicated tool interface for fluid infusion on the main monitoring interface, the central venous pressure trend information of the monitored object can be displayed in the dedicated tool interface for fluid infusion. The central venous pressure trend information can include at least one of a central venous pressure trend table and a central venous pressure trend graph. It can be understood that in this embodiment, the central venous pressure trend graph of the monitored object displayed on the dedicated tool interface for fluid infusion is mainly used as an example for explanation.

[0042] Continue reading Figure 3 Interface 301 is the above-mentioned dedicated tool interface for fluid infusion, and interface 302 is a central venous pressure trend graph of the monitored object under fluid infusion during a preset time period.

[0043] Step 105: Based on the acquired new central venous pressure monitoring data, the central venous pressure trend information displayed in the dedicated tool interface for fluid infusion is refreshed.

[0044] In this embodiment, since the central venous pressure monitoring data of the monitored object changes in real time during the fluid infusion, after the central venous pressure trend information is displayed on the dedicated fluid infusion tool interface, the monitoring device continues to monitor the central venous pressure of the monitored object in real time through the measuring device, generates central venous pressure trend information, and refreshes the central venous pressure trend information displayed in the dedicated fluid infusion tool interface according to the newly generated central venous pressure trend information. In other words, the central venous pressure trend information in the dedicated fluid infusion tool interface always displays the central venous pressure trend information of the monitored object acquired within the latest period of time (e.g., within 30 minutes).

[0045] In order to assist medical staff in judging the fluid replacement situation, a fluid replacement baseline corresponding to the monitored object can be generated and displayed on the central venous pressure trend graph, and a numerical value corresponding to the fluid replacement baseline can also be set. For example, the measured value of the central venous pressure when the fluid replacement situation special tool interface is opened can be used as the numerical value corresponding to the fluid replacement baseline, or the numerical value corresponding to the fluid replacement baseline can be determined based on the configuration information input by the user.

[0046] It is understandable that after the fluid infusion baseline corresponding to the monitored object is generated and displayed on the central venous pressure trend graph, a first identification line and / or a second identification line can be generated and displayed on the central venous pressure trend graph, and the first identification line and the second identification line are associated with the fluid infusion baseline, and the value corresponding to the first identification line is smaller than the value corresponding to the second identification line, and the value corresponding to the fluid infusion baseline is smaller than the value corresponding to the first identification line. In other words, the first identification line and the second identification line are two identification lines set on the basis of the fluid infusion baseline. It is understandable that the values ​​corresponding to the first identification line and the second identification line can also be determined based on the configuration information input by the user. The following is combined with Figure 3 To explain:

[0047] See also Figure 3, 302 is a central venous pressure trend graph under fluid infusion of the monitored object, 303 is the fluid infusion baseline corresponding to the monitored object, 304 is a first identification line, and 305 is a second identification line, wherein the first identification line and the second identification line are associated with the setting of the fluid infusion baseline, for example, the value corresponding to the first identification line is the value corresponding to the fluid infusion baseline + 2mmHg, that is, 2mmHg is added to the value corresponding to the fluid infusion baseline; the value corresponding to the second identification line is the value corresponding to the fluid infusion baseline + 5mmHg, that is, 5mmHg is added to the value corresponding to the fluid infusion baseline. It can be understood that the values ​​corresponding to the fluid infusion baseline, the first identification line, and the second identification line can be set by the doctor or nurse according to the actual situation of the monitored object. The above is only an example and does not represent a limitation on the values ​​corresponding to the first identification line and the second identification line.

[0048] The following describes how to determine the fluid infusion status of the monitored subject through the central venous pressure trend information of the monitored subject, based on the fluid infusion baseline, and the first identification line and / or the second identification line.

[0049] The monitoring device can measure the measured value of the central venous pressure of the monitored object in real time through the measuring device, and determine that when the measured value of the central venous pressure of the monitored object exceeds the value corresponding to the first identification line, a first prompt information is generated; and / or determine that when the measured value of the central venous pressure of the monitored object exceeds the value corresponding to the second identification line, a second prompt information different from the first prompt information is generated. Wherein: the first prompt information includes notification information indicating that it is necessary to suspend the fluid infusion of the monitored object, and the second prompt information includes notification information indicating that it is necessary to terminate the fluid infusion of the monitored object.

[0050] Continue reading Figure 3 During the process of rehydration of the monitored object, the monitoring device can obtain the central venous pressure trend information of the monitored object in real time and display it in a trend chart on the dedicated tool interface for rehydration (see Figure 3 302) in the form of display, and the first identification line (see Figure 3 304) and the second identification line (see Figure 3 304) is also displayed in the dedicated tool interface for fluid infusion, and a prompt message may be issued according to the intersection of the measured value of the central venous pressure of the monitored object with the first identification line or the second identification line. The following is an example of the first identification line being the value corresponding to the fluid infusion baseline +2 mmHg and the second identification line being the value corresponding to the fluid infusion baseline +5 mmHg:

[0051] If the measured value of the central venous pressure of the monitored subject at the current moment exceeds the first marking line, that is, the measured value of the central venous pressure of the monitored subject at the current moment is higher than the value corresponding to the fluid infusion baseline + 2 mmHg, a first prompt message is issued, and the first prompt message prompts to suspend fluid infusion for the monitored subject;

[0052] If the measured value of the central venous pressure of the monitored object at the current moment exceeds the second identification line, that is, the measured value of the central venous pressure of the monitored object at the current moment is higher than the value corresponding to the fluid infusion baseline +5mmHg, a second prompt message is issued, and the second prompt message indicates to terminate fluid infusion for the monitored object.

[0053] It should be noted that, in addition to obtaining the central venous pressure monitoring data of the monitored object under fluid infusion, the monitoring device can also obtain the monitoring data of the physiological signs of the monitored object associated with the fluid infusion situation, and the physiological signs associated with the fluid infusion situation include at least one of heart rate, arterial pressure (Art), non-invasive blood pressure (NIBP), blood oxygen and blood perfusion index. Specifically, the displayed blood oxygen monitoring data can be a blood oxygen saturation trend graph, blood oxygen saturation measurement value, etc.

[0054] In addition, after monitoring the physiological sign monitoring data of the monitored object associated with the fluid replacement situation, the monitoring device can generate a waveform graph and / or numerical information corresponding to the physiological signs associated with the fluid replacement situation based on the physiological sign monitoring data associated with the fluid replacement situation, and display the waveform graph and / or numerical information corresponding to the physiological signs associated with the fluid replacement situation in the fluid replacement situation-specific tool interface, and refresh the waveform graph and / or numerical information corresponding to the physiological signs associated with the fluid replacement situation displayed in the fluid replacement situation-specific tool interface based on the acquired new physiological sign monitoring data associated with the fluid replacement situation.

[0055] Combine the following Figure 3 , taking the physiological signs associated with fluid replacement as heart rate and arterial pressure as examples, see Figure 3 , 306 is a heart rate trend graph of the monitored object under the condition of fluid repletion within a preset time period, and 308 is real-time numerical information of the heart rate of the monitored object under the condition of fluid repletion (for example Figure 3 307 is a trend graph of arterial pressure of the monitored object under the condition of fluid infusion within a preset time period, and 309 is real-time numerical information of arterial pressure of the monitored object under the condition of fluid infusion (for example Figure 3 Of course, there are also changes in the monitoring data of other physiological signs related to the fluid rehydration of the monitored subjects ( Figure 3 It is understood that the process of the monitoring device in monitoring the physiological characteristics of the monitored object and the fluid infusion situation is similar to the process of monitoring the central venous pressure monitoring data, which has been specifically described above and will not be repeated here.

[0056] It should also be noted that when the dedicated tool interface for fluid infusion displays at least a central venous pressure trend graph and / or a waveform graph corresponding to a physiological characteristic associated with the fluid infusion situation (the waveform graph includes a physiological sign simulation signal waveform graph and a physiological sign trend graph), it can also generate and display a timeline in the trend graph and / or the waveform graph in response to the user's operation on the dedicated tool interface for fluid infusion, and display the measured values ​​of the central venous pressure and / or the physiological sign associated with the fluid infusion situation at the time point corresponding to the timeline. It is understandable that the trend graph and the waveform graph are identified using the same coordinate system, and the time axes of the two are consistent. The following is an explanation of the response to the user's operation on the dedicated tool interface for fluid infusion:

[0057] The user operates on the display of the monitoring device, and the monitoring device generates corresponding operation instructions, and in response to the operation instructions, generates and displays a timeline in a trend graph and / or a waveform graph, and displays the measured values ​​of the central venous pressure and / or physiological signs associated with the fluid infusion situation at the time point corresponding to the timeline.

[0058] It can be understood that the user's operation in the dedicated tool interface for fluid replenishment includes at least one of gesture operation, sliding operation, click operation and voice control operation. For example, when the user clicks on the display, the monitoring device can receive the click operation. At this time, the click operation generates an operation instruction. That is to say, the operation instruction can be defined in advance, such as defining in advance a sliding operation to display a timeline and a measurement value of a time point corresponding to the display timeline (such as a left slide operation, a right slide operation, an up slide operation and a down slide operation, etc.), or defining a click operation to display a timeline and a measurement value of a time point corresponding to the display timeline Values ​​(such as single-clicking the trend graph and / or waveform graph, double-clicking the trend graph and / or waveform graph, etc.), or defining gesture operations to display the timeline and the measured values ​​of the time points corresponding to the display timeline (such as swinging the wrist or arm to the left, swinging the wrist or arm to the right, such as four-finger pinching operations or three-finger swiping up operations, etc.), or defining voice control operations to display the timeline and the measured values ​​of the time points corresponding to the timeline (such as receiving the displayed sound to display the timeline and the measured values ​​of the time points corresponding to the timeline). The above is only an example and does not represent a limitation on the user's operations in the dedicated tool interface for fluid infusion.

[0059] To sum up, it can be seen that in the embodiments of the present invention, the monitoring device can monitor the central venous pressure monitoring data of the monitored object in real time during the process of fluid infusion for the monitored object, and generate central venous pressure trend information based on the central venous pressure monitoring data, and display it on the fluid infusion situation special tool interface. At the same time, the fluid infusion baseline and the first identification line and / or the second identification line are displayed in the fluid infusion situation special tool interface, and a prompt message is issued based on the intersection relationship between the measured value of the central venous pressure of the monitored object at the current moment and the first identification line and / or the second identification line, so as to assist the doctor or nurse in fluid infusion for the monitored object, which is used to improve the existing technology in which the doctor needs to watch and record the changes in the patient's central venous pressure parameters by himself when performing fluid therapy on the target object, and judge whether the fluid therapy needs to be terminated according to the parameter changes.

[0060] The above describes the embodiment of the present invention from the perspective of the physiological sign monitoring method for fluid infusion, and the following describes the embodiment of the present invention from the perspective of the monitoring device.

[0061] like Figure 4 As shown, a monitoring device is provided. The monitoring device has an independent shell, and a sensor interface area is provided on the shell panel, in which multiple sensor interfaces are integrated for connecting with external physiological sign sensor accessories 411. The shell panel also includes a small LCD display area, a display 419, an input interface circuit 422 and an alarm circuit 420 (such as an LED alarm area). The parameter processing module is an external communication and power supply interface for communicating with the host and taking power from the host. The parameter processing module also supports an external parameter module, and a plug-in monitor host can be formed by inserting the parameter module. As a part of the monitor, it can also be connected to the host through a cable. The external parameter module is an external accessory of the monitor.

[0062] The internal circuit of the parameter processing module is placed in the housing, such as Figure 4As shown, it includes a signal acquisition circuit 412 corresponding to at least two physiological parameters, a front-end signal processing circuit 413 and a main processor 415. The signal acquisition circuit 412 can be selected from an electrocardiogram circuit, a respiratory circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, etc. These signal acquisition circuits 412 are electrically connected to corresponding sensor accessories, respectively, and are used to be electrically connected to sensor accessories 411 corresponding to different physiological parameters. Its output end is coupled to the front-end signal processor, and the communication port of the front-end signal processor is coupled to the main processor. The main processor 415 is electrically connected to an external communication and power interface 416 (a power supply and battery management circuit 417 can also be included between the main processor 415 and the external communication and power interface 416). Various physiological parameter measurement circuits can adopt general circuits in the prior art. The front-end signal processor completes the sampling and analog-to-digital conversion of the output signal of the signal acquisition circuit, and outputs a control signal to control the measurement process of the physiological signal. These parameters include but are not limited to: electrocardiogram, respiratory, body temperature, blood oxygen, non-invasive blood pressure and invasive blood pressure parameters. The front-end signal processor can be implemented by a single-chip microcomputer or other semiconductor devices, or by ASIC or FPGA. The front-end signal processor can be powered by an isolated power supply, and the sampled data is simply processed and packaged before being sent to the main processor through the isolated communication interface. For example, the front-end signal processor circuit can be coupled to the main processor 415 through the isolated power supply and the communication interface 414. The reason why the front-end signal processor is powered by an isolated power supply is that the DC / DC power supply isolated by the transformer plays the role of isolating the patient from the power supply equipment. The main purposes are: 1. Isolate the patient, float the application part through the isolation transformer, and make the patient leakage current small enough; 2. Prevent the voltage or energy during the application of defibrillation or electric knife from affecting the boards and devices of the intermediate circuit such as the main control board (guaranteed by creepage distance and electrical clearance). The main processor completes the calculation of physiological parameters, and sends the calculation results and waveforms of the parameters to the host (such as a host with a display, a PC, a central station, etc.) through the external communication and power interface. The external communication and power interface 416 can be one or a combination of the local area network interfaces composed of Ethernet, Token Ring, Token Bus, and the fiber distributed data interface (FDDI) as the backbone network of these three networks. It can also be one or a combination of wireless interfaces such as infrared, Bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB. The external communication and power interface 416 can also be a combination of one or both of the wireless data transmission interface and the wired data transmission interface. The host can be any computer device such as the host of the monitor, an electrocardiograph, an ultrasonic diagnostic instrument, a computer, etc., and a monitoring device can be formed by installing the matching software.The host can also be a communication device, such as a mobile phone. The parameter processing module sends data to the mobile phone supporting Bluetooth communication through a Bluetooth interface to achieve remote transmission of data.

[0063] Wherein, the display 419 is configured to display information;

[0064] The memory 418 stores program instructions. When the main processor 415 executes the program instructions stored in the memory 418, the following method steps are implemented:

[0075] Alternatively, a numerical value corresponding to the fluid replenishment baseline is determined based on configuration information input by a user.

[0076] In one embodiment, the main processor 415 is further configured to implement:

[0077] A first identification line and / or a second identification line is generated and displayed in the central venous pressure trend graph, the first identification line, the second identification line are associated with the fluid infusion baseline, and the value corresponding to the first identification line is smaller than the value corresponding to the second identification line, and the value corresponding to the fluid infusion baseline is smaller than the value corresponding to the first identification line.

[0078] In one embodiment, the main processor is further configured to: generate a first prompt message when it is determined that the measured value of the central venous pressure of the monitored object exceeds the numerical value corresponding to the first identification line; and / or generate a second prompt message different from the first prompt message when it is determined that the measured value of the central venous pressure of the monitored object exceeds the numerical value corresponding to the second identification line.

[0079] In one embodiment, the first prompt information includes notification information indicating that it is necessary to suspend the fluid infusion for the monitored object, and the second prompt information includes notification information indicating that it is necessary to terminate the fluid infusion for the monitored object.

[0080] In one embodiment, the main processor 415 is further configured to: determine the value corresponding to the first identification line and the value corresponding to the second identification line based on configuration information input by a user.

[0081] In one embodiment, the main processor 415 is further configured to implement:

[0082] Acquiring physiological sign monitoring data of the monitored subject associated with the fluid infusion condition, wherein the physiological sign associated with the fluid infusion condition includes one or more of heart rate, arterial pressure, non-invasive blood pressure, blood oxygen, and blood perfusion index;

[0083] Generate a waveform graph and / or numerical information corresponding to the physiological sign associated with the fluid replacement situation based on the physiological sign monitoring data associated with the fluid replacement situation;

[0084] Displaying the waveform graph and / or numerical information corresponding to the physiological signs associated with the fluid replenishment condition on the fluid replenishment condition-specific tool interface;

[0085] Based on the acquired new physiological sign monitoring data associated with the fluid replacement situation, the waveform graph and / or numerical information corresponding to the physiological sign associated with the fluid replacement situation displayed in the fluid replacement situation dedicated tool interface is refreshed.

[0086] In one embodiment, when the dedicated fluid infusion tool interface displays at least a central venous pressure trend graph and / or a waveform graph corresponding to the physiological sign associated with the fluid infusion condition, the main processor 415 is further configured to implement:

[0087] In response to the user's operation in the dedicated tool interface for fluid infusion, a timeline is generated and displayed in the trend graph and / or waveform graph;

[0088] The measured values ​​of the central venous pressure and / or the physiological sign associated with the fluid replacement situation at the time point corresponding to the timeline are displayed.

[0089] To sum up, it can be seen that in the embodiments of the present invention, the monitoring device can monitor the central venous pressure monitoring data of the monitored object in real time during the process of fluid infusion for the monitored object, and generate central venous pressure trend information based on the central venous pressure monitoring data, and display it on the fluid infusion situation special tool interface.
