Description

Patient monitoring system and patient parameter information display method

Technical field

[0001] The present application relates to the field of medical monitoring technologies, and in particular, to a patient monitoring system and a patient parameter information display method.

[0002]

BACKGROUND

[0004] A monitor can be used to analyze and display various physiological and/or psychological parameters measured by one or more sensors connected to a patient. These parameters can be displayed in waveform or numerical form, where the waveform can display the value of the parameter within a certain period of time, and the value can display the current monitored value. Thus, the doctor can monitor the patient's physical condition using the monitor and identify the alarm based on the measured parameters.

[0005] At present, for patients undergoing surgery or under anesthesia, a multi-parameter monitor is usually used to monitor the patient's routine physiological parameters such as blood pressure, heart rate, and blood oxygen, and display in a multi-parameter monitor. The screen displays the waveforms, values, trends and other information related to the monitored physiological parameters, and uses B IS (bispectral index), single parameter monitor, and NMT (neuromuscular transmission). The instrument monitors and displays the patient's consciousness and muscle relaxation status. The doctor's anesthesia status for anesthetized patients needs to be judged by reviewing the information on multiple monitors and combining experience. However, on the one hand, due to the large amount of information on multiple monitors, it is inevitable for doctors to choose the parameter information useful for judging the patient's anesthesia status. On the other hand, these useful monitoring information are scattered on different monitors, doctors. Inevitably, one by one, it is necessary to make a comprehensive judgment on the part of the parameter information that the doctor first needs to remember and the current parameter information. In addition, each monitor may be provided by a different manufacturer, and the display style of the parameters is inconsistent. In these cases, the doctor's judgment on the patient's anesthesia status will be affected to some extent. Therefore, the current monitor or monitoring system cannot directly and effectively help the medical staff to judge whether the patient's anesthesia status is appropriate.

[0006]

The data processing module 30 And display module 50. Each module is described in detail below, and a description of a patient parameter information display method corresponding to the patient monitoring system is explained by the description.

[0032] The parameter acquisition module 10 is configured to obtain a data signal indicative of the anesthesia state of the patient. Consciousness, pain and muscle relaxation are three important dimensions for clinically determining the patient's anesthesia. Among them, the data signals related to consciousness and muscle relaxation can be obtained by monitoring BIS parameters and NMT parameters, but there is no direct monitoring parameter for pain. The monitoring system in the embodiment obtains information on the pain dimension by monitoring changes in the patient's blood pressure and heart rate, and changes in hormone levels in the patient. Of course, in other embodiments, the data signal representing the anesthesia state of the patient can also be obtained by monitoring other relevant parameters or by monitoring other related parameters and related parameters involved in the three dimensions enumerated in this embodiment.

[0033] The data processing module 30 is configured to process the data signal acquired by the parameter obtaining module 10, and generate the visualized display data by the processed result, where the visualized display data includes dimension information of multiple dimensions representing the patient's anesthesia state, wherein each The dimension information of the dimensions includes parameter information indicative of at least one parameter of the patient's anesthesia state. Taking the information of the three dimensions of consciousness, pain and muscle relaxation as an example, the visual display data here includes the consciousness dimension information, the pain dimension information and the muscle pine dimension information, wherein the consciousness dimension information and the muscle pine dimension information contain parameters. For example, the BIS parameter and the NMT parameter, and the pain dimension information may include at least one of a blood pressure change parameter, a heart rate change parameter, a hormone level change parameter in the patient, and the like, and the user may select a parameter of the pain dimension information according to the need. Number And the type, of course, the parameters of the consciousness dimension information and the muscle relaxation dimension information may also be set to the number/category, or the number and type of each dimension parameter may be fixedly set in advance. The parameter acquisition module can respectively acquire data signals representing measurement information of a certain parameter from a plurality of parameter sensors, and can also obtain parameter measurement values from other monitors.

The display module 50 has at least one anesthesia status display area 51 for displaying the visual display data generated by the data processing module 30 in the area 51, i.e., displaying dimensional information indicative of a plurality of dimensions of the patient's anesthesia status. As each dimension of the plurality of dimensional information has corresponding parameters, the information of the three dimensions of consciousness, pain and muscle relaxation is taken as an example, wherein the consciousness dimension information includes BIS parameters, and the muscle relaxation dimension information includes NMT parameters. The pain dimension information includes a blood pressure (BP) change parameter, a heart rate (HR) change parameter, and a hormone level change parameter in the patient, so the display module 50 can display all of these parameters in the anesthesia state display area 51 accordingly. As shown in FIG. 3 (the two-dimensional graph is only an illustrative example, and is not intended to limit the actual measurement results of the present example, but is used to describe each dimension information that can be presented in the display module of the present embodiment), thereby The medical staff can be helped to determine if the patient's anesthesia is appropriate based on the information displayed. The display module 50 can be, for example, a touch or non-touch display or the like. Of course, the display module 50 can also be a display screen provided by the existing monitoring device, and in addition to the at least one anesthetic state display area 51, can also include data signals related to displaying conventional physiological parameters or other physiological parameters, including pulse rate and body temperature. The conventional display area 52 of respiratory rate or venous oxygen saturation, hemodynamics, etc., the anesthesia status display area 51 and the conventional display area 52 are independent of each other. As shown in FIG. 2, it can be specifically implemented by referring to related technologies of the existing monitor. The conventional display area 52 can be divided into a plurality of parallel sub-display areas according to the horizontal direction, and each sub-display area displays information of one parameter. In a specific embodiment, the anesthesia status display area 51 is located at the lower left corner of the monitor display screen, or at the center of the display screen, and in some cases, the anesthesia status display area 51 and the conventional display area 52 display information. Without overlapping, the anesthesia status display area 51 may be set to cover a portion of the regular display area 52 in some cases (in some cases, the entire monitor display screen may be regarded as a regular display area). Conversely, the anesthesia status display area 51 can also cover the entire screen or be displayed separately by another networked/associated monitor/monitoring system. By presenting parameter information that can characterize various dimensions of the anesthesia state in the anesthesia state display area 51, the medical staff can quickly view the parameter information of each dimension of the patient's current engraving, thereby quickly determining whether or not it is needed or how Take the next step.

[0035] This embodiment provides information on the anesthesia status of a patient by monitoring information indicative of the patient's anesthesia status from a plurality of dimensions such as consciousness, pain, and muscle relaxation, and displaying the dimensional information of each dimension and its respective parameters. A comprehensive organization and presentation from multiple dimensions helps to visually help medical staff determine whether the patient's anesthesia is appropriate.

[0036] The parameter monitoring module 10, the data processing module 30, and the display module 50 included in the patient monitoring system in this embodiment are only divided into three modules according to different functions, but the module is divided, The number, etc. can be set to a number of different settings depending on the situation. For example, the parameter obtaining module 10 may be various parameter modules of the plug-in type monitor or a parameter board inside the non-plug-in type monitor. The data processing module 30 may be a main control unit of the plug-in type monitor or a host of the monitor; the parameter acquisition module 10 may also be an interface of the monitor main control unit to obtain data signals transmitted from sensors or other monitors and networks; the parameter acquisition module 10 may also refer to a sensor that obtains the original sensing data signals, and the data processing unit may include One or more modules, as long as the raw sensory data signals are processed into visual parameter information that ultimately characterizes the patient's signs.

[0037] Embodiment 2:

[0038] As shown in FIG. 1 and FIG. 2, the patient monitoring system provided in this embodiment also includes a parameter acquisition module 10, a data processing module 30, and a display module 50 that are sequentially connected. The functional description of each module is described with reference to the description of the first embodiment. The following specifically describes how the display module comprehensively presents multi-dimensional information representing the anesthesia state of the patient. In addition, a patient parameter information corresponding to the patient monitoring system is described by the following description. Display method.

In this embodiment, each anesthesia state display area 51 included in the display module 50 has a plurality of sub-areas, the number of sub-areas is equal to the number of dimensions of the plurality of dimensions, and one sub-area corresponds to one dimension, and each sub-area displays corresponding Dimension information for dimensions. Taking the information of the three dimensions of consciousness, pain and muscle relaxation as an example, the dimensional information of the three dimensions of consciousness, pain, and muscle relaxation is displayed in the anesthesia state display area 51, and the anesthesia state display area 51 includes or divides. For the three sub-regions 511, 512, 513, as shown in FIG. 2, the three sub-regions are respectively used to display the consciousness dimension information, the pain dimension information and the muscle relaxation dimension information, wherein each dimension information includes at least one parameter corresponding to each, for example The consciousness dimension information includes BIS parameters, the muscle relaxation dimension information includes NMT parameters, and the pain dimension information includes BP variation parameters and HR variation parameters. These parameters are used to characterize the patient's anesthesia. In the present embodiment, the parameter characterizing the anesthesia state of the patient is one or a combination of physiological parameters and psychological parameters.

[0040] The parameter information of each parameter includes a name of the parameter and one or a combination of a current monitoring value selected from the parameter, a parameter change trend of the parameter, and a normal abnormality indicator, that is, the parameter information includes a parameter. The current monitoring value of the name and parameter, or the parameter change trend including the parameter name and parameter, or include the parameter name and the normal abnormality indicator, or include the parameter name, the current monitoring value, and the parameter change trend, or include the parameter name and the current monitoring value. And normal abnormality indicators, or include parameter names, current monitoring values, parameter change trends, and normal abnormality indicators. The normal abnormality indicator indicates that the current monitoring value falls within the preset threshold corresponding to the parameter, and the identifier indicating that the characteristic parameter is normal is displayed, and the current monitoring value falls outside the preset threshold corresponding to the parameter. An identifier that identifies a parameter anomaly. The preset threshold may be an empirical value, and the system default setting or the system provides a human-computer interaction interface through which the user-entered custom value is received. The parameter name can be text in various languages, or it can be an icon or a schematic diagram, which can be concisely expressed in the meaning of the dimension, the measured value of the parameter in the dimension, the presentation form of the measured value on the real interface, and the like. In the case where the meaning of the dimension of the parameter can be clearly expressed, the parameter name may be omitted or not displayed.

[0041] In an embodiment, each sub-area may be dimension information that only displays the corresponding dimension in a text manner, and the sub-area 511 displays the consciousness dimension information including the BIS parameter as an example, and the text is directly in the sub-area 511. The mode presents related information about the BIS parameters, such as the currently monitored BIS parameter value, whether the monitored BIS parameter is normal or abnormal, and the like; other sub-areas are similar.

[0042] In another embodiment, each sub-area may also display the dimension information of the corresponding dimension only in a graphical manner, and still display the consciousness dimension information including the BIS parameter in the sub-area 511 as an example, and the sub-area 511 is directly in the sub-area 511. Graphically present information about BIS parameters, such as using a histogram and its varying height or length or width to reflect changes in the monitored values of the monitored BIS parameters, or using a histogram combined with different colors to reflect the monitored BIS Whether the parameters are normal, etc.; other sub-areas are similar.

[0043] In this context, the graphical manner includes at least one of a graphic and a combination of a graphic and a color and/or a pattern, that is, the graphic mode is a combination of graphics and color, or the graphic mode is a combination of graphics and graphics. , or graphically, the combination of graphics, colors, and graphics. The graphic can be, for example, a line, a column, a sector, a meter, a two-dimensional graph, one of a list, or any group thereof Hehe.

In this embodiment, each sub-area presents the dimensional information of the corresponding dimension in a textual manner and in a graphical manner. The information for each sub-area is presented in the same way. For example, as shown in FIG. 4, the sub-area 511 displays the consciousness dimension information including the BIS parameter, wherein the dimension name (awareness) of the dimension, the name of the parameter (BIS) included in the dimension, and the parameter are displayed in text form. The current monitored value (67), which is graphically represented, ie, the dimension is presented in a histogram, and the normal anomaly indicator of the parameter is presented in conjunction with the pattern (the intersection of the scribe lines in the illustration) The intersection of the scribe line indicates an abnormality, that is, the current monitoring value falls outside the preset threshold corresponding to the parameter 吋), and the preset threshold value 5114 may also be shown in the illustration (the preset threshold may also be referred to as a threshold line, a threshold value) The position of the mark) may of course not show the threshold (ie, the thick line corresponding to 5114 does not exist in the map); similarly, the sub-area 512 displays the muscle pine dimension information including the NMT parameter, wherein, Form shows the dimension name for this dimension

(muscle loosening), the name of the parameter contained in the dimension (NMT) and the current monitored value of the parameter (8), graphically showing the dimension, ie using the histogram to present the dimension, combined with the pattern (in the illustration The underlined part) presents a normal abnormality indicator of the parameter (the underlined part of the figure indicates an abnormality, that is, the current monitored value falls outside the preset threshold corresponding to the parameter), and the illustration may also show The position of the preset threshold 5124 may of course not be shown (ie, there is no thick line corresponding to 5124 in this map); the sub-area 513 shows two parameters (such as BP change parameter and HR change parameter). Pain dimension information, where the dimension name (pain) of the dimension, the names of the two parameters contained in the dimension (ΔΒΡ and AHR), and the current monitored values of the two parameters (+35 and +10) are displayed in text form , graphically showing the dimension, that is, using two histograms to present the two parameters contained in the dimension, and combining the patterns (the underlined part and the crossed line in the illustration) It presents the parameters of normal exception indicator

(The scribe line portion and the scribe line intersection portion indicate an abnormality, that is, the current monitoring value falls outside the preset threshold corresponding to the parameter 吋), and the position of the preset threshold value 5134 may also be shown in the illustration, of course. The threshold may not be shown (ie, there is no thick line corresponding to 5134 in this map). Other marking methods can also be used in the illustration. For example, the position of the current monitoring value is marked by a triangle, an arrow or other symbols on a histogram or a line, and the like, and then combined with the marked threshold line, can be displayed very intuitively. The patient is anesthetized. A person skilled in the art can also make corresponding modifications to the present embodiment by referring to the existing way of marking on the graphic. As shown in FIG. 4, three sub-regions 511, 512, and 513 form a spider web. In other examples, the three sub-regions may also be other patterns, such as the layered placement shown in FIG. 5, or juxtaposed (ie, rotated 90 degrees as shown in FIG. 5), or three dimensions forming a triangle. Ways and so on.

[0045] The pattern shown in FIG. 4 may also be replaced by a color or other pattern, and the pattern may also be replaced with, for example, a meter shape (as shown in FIG. 7), a fan shape (as shown in FIG. 6), and the like, each sub-area. The parameter information can be presented together with both columnar and two-dimensional coordinates. The specific implementation of the parameter information presentation of each parameter can be implemented by referring to the related related art. For example, the specific implementation of using the trend line (ie, two-dimensional coordinate map) or the table (ie, the list) to present the parameter change trend can refer to the existing monitor. Methods such as the presentation of an electrocardiogram. In the embodiment shown in FIG. 6, the monitoring system indicates the name or meaning of each dimension through a sector area, and indicates the parameter information of each dimension in combination with the histogram, and can also directly indicate the area size of the sector area. Information about the parameter values, and set the threshold line in the sector.

[0046] In the embodiment shown in FIG. 4, the sub-regions for displaying different dimensional information are substantially rotationally symmetrically distributed, and the rotation angle thereof is less than 180 degrees. Specifically, the three sub-regions 511, 512, and 513 are distributed in three. Divide a circle of three bisectors with a rotation angle of approximately 120 degrees. For the distribution relationship of multiple sub-areas, different changes can be made, for example, the center of the display area of the anesthesia state is still used as a base point for divergent arrangement, but the mutual angles and distances between the sub-areas can be set to be different from each other, for example, The two sub-regions are on the same horizontal line, and the remaining sub-regions are located between the two sub-regions and are perpendicular to the two. As the dimension decreases or increases, more corresponding changes can be made. Compared with the parallel arrangement of the sub-regions in Fig. 5, the rotationally symmetric arrangement is visually more intuitive to show that there is a certain internal relationship between the dimensions. In addition, in the embodiment corresponding to FIG. 4, the pain dimension has two parameters arranged side by side, and of course, the parameters of the dimension may be arranged side by side, and the arrangement manner is not limited to the vertical arrangement. It can be arranged in a lateral juxtaposition or a rotationally symmetric distribution.

[0047] In the present embodiment, multiple dimensions such as patient consciousness, muscle relaxation, and pain, and related parameters are comprehensively presented in a graphical manner to indicate the patient's current anesthesia status. The composite presentation consists of two levels. One of the levels is the presentation of anesthesia dimensions, in which multiple sub-regions corresponding to multiple dimensions are graphically represented (eg, three sub-regions correspond to the three dimensions of patient anesthesia, muscle relaxation and pain), and each anesthesia-related parameter is followed by clinical guidance. The difference in meaning is shown in the corresponding areas of patient consciousness, muscle relaxation and pain dimensions, and the like. Of course, the user can customize the number, name and each of the divided dimensions. The parameters contained in the dimension (see Example 3). Another level is the presentation of anesthesia parameters, such as the graphical representation of the anesthesia-related parameters, the size of the parameter monitoring values indicated by the histogram fill height, and the current parameter by the color or pattern of the histogram fill. Whether the status is normal or abnormal. Through this layered approach, a comprehensive indication of the anesthesia status allows the doctor to view the general information from the general information to the specific information, without having to dig through various related information to understand the current anesthesia status of the patient, and to improve the use of the monitoring system to a certain extent. And operability. For the embodiment, the identifier for distinguishing between the normal area and the abnormal area may be provided on the histogram, for example, the pattern of filling the histogram, the color block, and the like. In addition, the user may also customize the threshold of the parameter abnormality, or preset the threshold. It can also be set to the empirical value by default. The dimension name can be displayed next to the corresponding dimension information by text, icon, schematic, thumbnail, etc., or even the dimension name or the dimension information represented by the centralized display in the centralized display.

[0048] Embodiment 3:

[0049] As shown in FIG. 8, the patient monitoring system provided in this embodiment is an improvement to the foregoing embodiment 1 or 2. Specifically, the system includes a parameter acquiring module 10, a data processing module 30, and a display module 50, which are sequentially connected. In addition, the setting module 70 is further configured to be connected to the data processing module 30 for automatically setting or setting according to the information to be displayed input by the user, the information to be displayed includes dimension information of a multidimensional dimension representing the anesthesia state of the patient, and each dimension Name, the number of parameters included in each dimension, and the parameter information corresponding to each parameter. The automatic setting here means that the presentation can be automatically organized according to the parameters currently monitored by the patient monitoring system, and the setting according to the user input can be divided by the user according to actual needs, for example, according to the system of the human body, and different parameters are divided according to the system. And through the aforementioned graphical presentation mode for comprehensive presentation.

[0050] In the first embodiment or the second embodiment, the system is equivalent to the default presence setting module, but the setting module automatically sets the information to be displayed, for example, only three dimensions of consciousness, muscle relaxation and pain are set, and in this embodiment, The setting module 70 can be set according to the needs of the user. It can be understood that the patient monitoring system provides a human-computer interaction interface for the user to input its settings. For example, as shown in FIG. 9, by the setting value area 519 provided on the anesthesia state display area 51 of the display module 50, the user can set the value. The locale is to be displayed. The implementation of the set value area and its association with the setting module 70 can be referred to known software desktop and background design methods, and will not be described in detail herein. [0051] In addition, in another embodiment, the setting module 70 may also be used to set the inter-turn length involved in the parameter change trend, and the inter-turn length may also be automatically changed according to the system, or may be performed by the user. definition.

[0052] Embodiment 4:

[0053] The patient monitoring system provided in this embodiment is an improvement to the foregoing embodiment one or two or three, and the improvement is that the system also provides an indication of the basic level of vital signs parameters of the patient before anesthesia, as shown in FIG. Each anesthesia state display area 51 further includes a reference value area 518 for displaying a vital sign parameter base level, which can be set by one of the following means or any combination thereof:

[0054] a) obtaining the mean value of the parameters within a period of time after the beginning of the monitoring is automatically used as the basic level of the vital signs of the patient before anesthesia;

[0055] b) the user can manually obtain a certain engraving vital sign parameter value as the basic level of the patient's vital signs before anesthesia;

[0056] c) The user can manually set the basic level value of the vital sign parameters before anesthesia.

[0057] This embodiment provides an indication of the basic level of the vital signs of the patient before anesthesia, and the graphical representation of the change trend of the anesthesia-related monitoring parameters after the patient is anesthetized, thereby helping the medical staff to intuitively Determine whether the patient's anesthesia parameters change trend and whether the anesthesia status is appropriate. In this embodiment, the basic level of vital sign parameters before anesthesia can be replaced with the vital sign parameters of the patient during anesthesia, or the basal level of vital signs before anesthesia and the vital signs of the patient during anesthesia.

[0058] It can be seen that in various embodiments of the present application, the anesthesia state is comprehensively presented through three dimensions, such as consciousness, pain, and muscle relaxation, and can be applied to various monitoring devices such as an anesthesia machine and a ventilator with monitoring functions, wherein There may be multiple parameters in a dimension or multiple dimensions to jointly characterize the state of the single dimension. For example, the pain dimension may contain at least two parameters such as HR variation parameters and BP variation parameters because it has no direct monitoring parameters; Presenting an anesthetic state, in one embodiment, a threshold line can be set on each of the parameter representation graphs (such as the histogram, gauge, pie chart, etc.), and/or current monitoring is displayed in each dimension direction. Value (such as marking the location of the parameter value on the histogram), and/or marking the current normal/abnormal condition of the dimensional parameter with a color or pattern based on the relationship to the threshold range, thereby providing an intuitive assessment of whether the patient's anesthesia is appropriate and anesthesia Parameter change trend, etc. Due to concentration in anesthesia The same area presents the parameter information of multiple dimensions, and the medical staff can quickly and effectively view the information to accurately determine the patient's anesthesia status.

[0059] The comprehensive anesthesia state presentation method of the monitoring system in the present application may further perform more specific implementation variants according to requirements, for example, the parameter values and threshold lines of each dimension may be automatically omitted according to the currently monitored patient state, only when The specific parameter information is displayed only when the status is abnormal, or only the parameter information of one of the dimensions is displayed. Other dimensions only retain the dimension name and the color indicating whether the current is normal, and the like, and are not described one by one.
