Referring to fig. 1, fig. 1 is a schematic diagram of an embodiment of an interface displaying method for a medical monitoring device according to an embodiment of the present invention, including:

step 101, providing an operation guidance area and a parameter display area on a main monitoring interface of the medical monitoring equipment.

In this embodiment, when performing a PLR test, an operation guidance area and a parameter display area are provided on a main monitoring interface of a medical monitoring device, which is described below with reference to fig. 2:

referring to fig. 2, fig. 2 is a schematic view of a main monitoring interface of a medical monitoring device according to an embodiment of the present invention, in which a region 201 is an operation guidance region, and a region 202 is a parameter display region.

And 102, displaying prompt information in the operation guide area.

In this embodiment, the prompt information may be displayed in the operation guidance area of the main monitoring interface of the medical monitoring device, where the prompt information is used to instruct to adjust the placement state of the monitored object, and the placement state is a body position state used to display that the monitored object performs a PLR test, and may be specifically realized by adjusting an angle of a bed where the monitored object is located.

The prompt information may be, for example, the prompt information "Phase 1, Check that is at 45 ° after forward press contact" displayed in the area 201 in fig. 2, and the graphical display information, and the above description of the prompt information is not intended to be limiting, and it is needless to say that other prompt methods, such as prompt in the form of animation or voice, may be used.

It should be noted that the placement state of the monitored object includes a first state and a second state, after the prompt information is obtained, the prompt information may be displayed to the user, so that the user may adjust the placement state of the monitored object to the first state or the second state according to the prompt information, that is, the prompt information may be displayed to the user, and the user may adjust the bed angle of the monitored object according to the indication of the prompt information; the medical monitoring device may also control the bed associated with the medical monitoring device according to the prompt information, and adjust the bed to an angle corresponding to the first state or the second state, that is, the medical monitoring device may automatically adjust the bed angle of the monitored object based on the prompt information.

And 103, acquiring monitoring data of the physiological signs of the monitored object after the placement state is adjusted.

In this embodiment, when the PLR test is performed on the monitoring subject, the monitoring data of the physiological signs of the monitoring subject after the adjustment of the placement state can be acquired. Wherein, this monitoring data includes first monitoring data, second monitoring data and third monitoring data, and is specific:

when a monitored subject is in a first state, acquiring first monitoring data of physiological signs of the monitored subject in the first state;

when the monitored object is adjusted from the first state to the second state, acquiring second monitoring data of the physiological signs of the monitored object in the second state;

and when the monitored subject is adjusted from the second state to the first state, acquiring third monitoring data of the physiological signs of the monitored subject in the state that the second state is adjusted to the first state.

That is to say, during the PLR test, the initial placement state of the monitored subject is the first state, when the placement state of the monitored subject is adjusted to the first state, the physiological sign parameter of the monitored subject in the first state is recorded as the first monitoring data, when the placement state of the monitored subject is adjusted from the first state to the second state, the physiological sign parameter of the monitored subject in the second state is recorded as the second monitoring data, and when the placement state of the monitored subject is adjusted from the second state to the first state, the current physiological sign parameter of the monitored subject is recorded and determined as the third monitoring data.

It should be noted that the first monitoring data, the second monitoring data, and the third monitoring data are data within a preset time period obtained when the monitoring object is in the corresponding placement state, for example, the first monitoring data is data within two minutes when the monitoring object is in the first state, and the preset time period may also be set according to an actual situation.

It can be understood that after the prompt information is displayed in the operation guidance area of the main monitoring interface, the medical monitoring device can receive a starting instruction input by a user; in response to an initiating instruction, initiating data measurements of physiological signs while the monitoring subject is in a first state or a second state; or acquiring angle information of a bed associated with the medical monitoring equipment; when the angle information is determined to match the angle corresponding to the first state or the second state, data measurement of the physiological signs of the monitored subject is started.

In some embodiments, the first monitoring data, the second monitoring data, and the third monitoring data may be measured when the monitoring object is completely in the first state or the second state, or may be measured during the adjustment between the first state and the second state.

In one embodiment, the start instruction may be an operation instruction of the region 204 in fig. 2 by a user, and the operation of generating the start instruction at least includes one of a gesture operation, a sliding operation, a clicking operation, and a voice control operation, for example, when the user clicks the region 204, the medical monitoring device may receive the clicking operation, and then the clicking operation generates the start instruction, that is, the start instruction may be defined in advance, for example, the sliding operation is defined in advance to start data measurement of a physiological sign when the monitoring subject is in the first state or the second state (e.g., left sliding operation, right sliding operation, up sliding operation, down sliding operation, and the like), or the clicking operation triggers start of data measurement of the physiological sign when the monitoring subject is in the first state or the second state (e.g., operation of the clicking region 204 or operation of the double-clicking region 204, and the like), or, the gesture operation is defined to trigger the data measurement of the physiological signs when the monitored subject is in the first state or the second state (for example, the wrist or the arm is swung left, the wrist or the arm is swung right, for example, four fingers are operated in a retracting manner or three fingers are operated in a sliding manner, etc.), or the voice control operation is defined to trigger the data measurement of the physiological signs when the monitored subject is in the first state or the second state (for example, the voice which starts the data measurement of the physiological parameters of the monitored subject is received, that is, the data measurement of the physiological signs when the monitored subject is in the first state or the second state is triggered), which is only an example and does not represent a limitation on the operation of generating the start instruction.

It should be noted that, in response to a first operation instruction input by a user, the medical monitoring device may display a setting interface on the main monitoring interface, where the setting interface is used to set a preset time length, for example, may receive an operation of the user on the area 203 in fig. 2, and generate the first operation instruction according to the operation of the user on the area 203, and display the setting interface (not shown in fig. 2).

In one embodiment, the operation of generating the first operation instruction at least includes one of a gesture operation, a sliding operation, a clicking operation and a voice control operation, for example, when a user clicks on the area 203, the medical monitoring device may receive the clicking operation, and at this time, the clicking operation generates the first operation instruction, that is, the first operation instruction may be defined in advance, for example, a sliding operation triggering entering setting interface (e.g., a left sliding operation, a right sliding operation, a sliding up operation, a sliding down operation, etc.) is defined in advance, or a clicking operation triggering entering setting interface (e.g., an operation of the area 203 area of the single click area or an operation of the double click area 203, etc.) is defined, or a gesture operation triggering entering setting interface (e.g., a wrist or arm swinging to the left, a wrist or arm swinging to the right, a wrist or arm retracting operation with four fingers, or a, or defining the voice control operation as triggering the entry setting interface (for example, entering the setting interface when receiving a sound entering the setting interface), which is only an example and does not represent to limit the operation of generating the first operation instruction.

It should be noted that the physiological signs of the monitored subject include at least one of stroke volume, cardiac output, end-tidal carbon dioxide, arterial pressure, central venous pressure, stroke volume index, cardiac output index, and heart rate, and may also include other physiological sign parameters, which are not limited in particular.

And 104, displaying the monitoring data in the parameter display area.

In this embodiment, after obtaining the monitoring data of the physiological signs of the monitoring subject after adjusting the placement state, the medical monitoring device may display the monitoring data in a parameter display area, specifically, the parameter display area of the main monitoring interface of the medical monitoring device includes a first display area, a second display area, and a third display area, where the first display area is used for displaying the first monitoring data, the second display area is used for displaying the second monitoring data, and the third display area is used for displaying the third monitoring data. As shown in fig. 2, the region 2021 is a first display region, the region 2022 is a second display region, and the region 2023 is a third display region, in practical applications, the first monitoring data is displayed in the region 2021, the second monitoring data is displayed in the region 2022, and the third monitoring data is displayed in the region 2023 (specific monitoring data is not shown in fig. 2).

It can be understood that, the trend graph and/or the numerical information corresponding to the monitoring data is displayed in the parameter display area, which is described below with reference to fig. 3:

referring to fig. 3, fig. 3 is another schematic view of a main monitoring interface of a medical monitoring device according to an embodiment of the present invention, in which a trend graph corresponding to monitoring data is displayed in an area 301 of fig. 3, and numerical information corresponding to the monitoring data is displayed in an area 302 (the trend graph and the numerical information of the monitoring data of a monitoring object shown in fig. 3 are only for illustration and do not represent a limitation thereto).

It should be noted that, after the first monitoring data, the second monitoring data, and the third monitoring data are obtained, the second monitoring data may be compared with the first monitoring data to obtain a first comparison result, where the first comparison result at least indicates a change percentage of the second monitoring data relative to the first monitoring data, and specifically, when the second monitoring data is compared with the first monitoring data, the comparison data selected from the second monitoring data is a maximum value of a physiological sign parameter in the second monitoring data (the maximum value may be set by a medical worker observing the second monitoring data, and may also be automatically set by a medical monitoring device); the selected contrast data in the first monitoring data is the monitoring data of the monitoring subject when the physiological sign parameters of the monitoring subject are kept stable in the first state, or the monitoring subject starts to test the physiological sign parameters to the average value in the time period when the physiological sign parameters of the monitoring subject are kept stable from the adjustment placement state of the monitoring subject in the first state (the monitoring data when the physiological sign parameters of the monitoring subject are kept stable can be set by observation of medical personnel, and medical monitoring equipment can also be set by itself according to the acquired first monitoring data, and is not limited specifically, and similarly, the monitoring subject starts to test the average value in the time period when the physiological sign parameters of the monitoring subject are kept stable from the adjustment placement state of the monitoring subject in the first state, and can be set like the above), and the contrast data can be defined as a baseline value. In the PLR test, the first comparison result mainly reflects the capacity reactivity state of the monitored subject.

It is understood that the medical monitoring device may also compare the third monitored data with the first monitored data to obtain a second comparison result, the second comparison result indicating at least a percentage change of the third monitored data relative to the first monitored data. In the process of comparing the first monitoring data with the third monitoring data, the manner of selecting the comparison data is similar to that of the first monitoring data (also selecting the physiological sign parameter when the physiological sign parameter is kept stable or the average value of the physiological sign parameter for comparison), which has already been described in detail above, and is not described again here. In the PLR test, the second comparison result can be used to determine whether the relevant physiological signs can be restored to the initial baseline value after the monitoring subject has changed the position status.

It should be noted that, when the parameter display area displays the trend graph corresponding to the monitoring data, the time line may be generated and displayed in the trend graph in response to the operation of the user in the parameter display area; and displaying the measured values of the physiological signs at the time points corresponding to the time lines.

After the monitoring data of the monitored object is obtained, the monitoring data may be transmitted to other devices associated with the medical monitoring device for display, or a print report may be generated based on the monitoring data and output to the printing device associated with the medical monitoring device for printing. The printed report can display a complete trend chart of the monitoring data in the PLR test process, and marks of the adjusting completion time of each placing state, a baseline mark (the baseline mark is contrast data obtained from the first monitoring data) and a maximum change time mark of the monitoring data.

In summary, it can be seen that, in the embodiment of the present invention, the PLR test process is graphically guided by using a method of prompting information in the operation guidance area of the main monitoring interface of the medical monitoring device, and the monitoring data of the physiological signs of the monitored object in the PLR test process is displayed in the parameter display area of the main monitoring interface, so that the medical staff can be helped to perform the PLR test on the monitored object, and the medical staff does not need to manually record the monitoring data, which can bring great convenience to the doctor.

The internal circuit of the parameter processing module is disposed in the housing, as shown in fig. 4, and includes at least two signal acquisition circuits 412 corresponding to physiological parameters, a front end signal processing circuit 413 and a main processor 415, where the signal acquisition circuits 412 may be selected from an electrocardiograph circuit, a respiration circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, and the like, these signal acquisition circuits 412 are respectively electrically connected to corresponding sensor accessories for electrically connecting to the sensor accessories 411 corresponding to different physiological parameters, and an output end thereof is coupled to the front end signal processor, a communication port of the front end signal processor is coupled to the main processor, and the main processor is electrically connected to an external communication and power interface (the main processor 415 and the external communication and power interface 416 may further include a power supply and battery management circuit 417). The various physiological parameter measuring circuits can adopt a common circuit in the prior art, a 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 measuring process of the physiological signal, and the parameters include but are not limited to: electrocardio, respiration, body temperature, blood oxygen, noninvasive blood pressure and invasive blood pressure parameters.
