Description

Medical equipment system display method and medical equipment system

Technical Field

The invention relates to the field of medical equipment, in particular to a display method of a medical equipment system and the medical equipment system.

Background

Critical patients have the characteristics of complex illness state, multiple changes, multiple subjects, high-tech equipment application, human ethics related problems and the like, so that critical disease medicine is the product of the development and integration trend of medical branch subjects, and the integration simultaneously determines the requirements and challenges on the clinical thinking of ICU doctors, wherein the most prominent is comprehensive thinking. Namely, in a severe scene, doctors need to comprehensively analyze according to own clinical experience and logic reasoning, judge the current pathophysiological state of the patient and make proper clinical decisions in the face of pathophysiological indexes and parameters of different organs, different equipment, different means and different times.

When the quantitative analysis of cardiac function and circulatory function is carried out, the cardiac ultrasonic image and the cardiac ultrasonic measurement index are presented simultaneously with parameters such as ECG, blood pressure and the like, which is helpful for a clinician to evaluate from more dimensions.

When the capacity management is carried out, the capacity state and the capacity reactivity of the patient can be rapidly and conveniently judged through the heart-lung interaction. And various indications of cardiopulmonary interaction require the user to comprehensively analyze in combination with ultrasonic images and breathing machine parameters. For example, the change index of the internal diameter of the inferior vena cava along with expiration and inspiration is judged by the ventilation pressure waveform.

At present, physiological parameter information of ultrasonic diagnostic equipment, monitors and respirators are displayed on respective screens, and doctors need to manually export the respective information, manually align the information and perform relevant analysis. Time and effort are wasted. Is inconvenient for clinical scientific research.

This is explained in detail below by means of some examples.

The medical equipment system provided by the invention is positioned under a local area network or a wide area network during working, namely, all medical equipment of the medical equipment system can be connected through communication of the local area network or the wide area network. The medical device system includes a plurality of medical devices, some or all of which may be used to perform a display method of the medical device system. The following describes in detail the display method of the first medical device and the third medical device as execution subjects, respectively.

Embodiment one:

in this embodiment, the display method of the medical device system is applied to a first medical device of a plurality of medical devices of the medical device system, as shown in fig. 1 and 2, and includes the steps of:

step 1, the first medical device 10 displays additional information of a plurality of target medical devices. Specifically, the first medical device 10 receives a display instruction of additional information of a plurality of target medical devices, wherein the plurality of target medical devices are at least two of the plurality of medical devices except the first medical device 10. In this embodiment, the plurality of target medical devices are all medical devices except the first medical device 10 among the plurality of medical devices. The additional information of the plurality of target medical devices is used to identify attributes of the plurality of target medical devices. The additional information of the target medical device is used to uniquely identify the target medical device or the patient to which the target medical device belongs, e.g. the additional information may comprise a device identification and/or a patient identification. The device identification is used to identify the medical device, which may be a device ID, a device name, a device model number, etc. The patient identification is used to identify the patient, which may be a patient ID, patient name, patient room number, hospital bed number, etc. Additional information if a patient is identified, the additional information for a plurality of target medical devices for the patient is the same, and selecting one additional information selects each target medical device for the patient identified.

The first medical device 10 may comprise human-machine interaction means. The man-machine interaction device is used for carrying out man-machine interaction, namely outputting visual information and receiving input of a user. Input devices such as a keyboard, buttons, a mouse, a track ball and the like can be used for receiving the input of a user, and a touch screen integrated with a display can also be used; the output visual information can be a display. The display instruction of the additional information of the plurality of target medical devices may be triggered by a physical key or a virtual key of the input device. In this embodiment, the display instruction is automatically triggered after the first medical device 10 joins the local area network or the wide area network, that is, the medical staff can network the first medical device 10 through the input device, and automatically trigger the display instruction after networking, although other embodiments may also be manually triggered.

The first medical device 10 displays additional information of the plurality of target medical devices on a display interface of a display of the first medical device 10 in response to the display instruction. Wherein the additional information may be displayed in the form of text or icons. In this embodiment, the additional information of the plurality of target medical devices is optional as shown in a of fig. 3.

The first medical device 10 has communication connection authority to each medical device of the medical device system under the local area network or the wide area network, that is, the subsequent first medical device 10 can be in communication connection with any medical device in the medical device system. The first medical device 10 has a network setting interface, and the user calls out the network setting interface through a preset key, and the network setting interface displays a connection mode of a local area network or a wide area network for the user to select, where the connection mode is wired, wireless, and the like.

The first medical device 10 may obtain the additional information of the plurality of target medical devices via a local area network or a wide area network before displaying the additional information. There are various specific modes, and the following are three modes.

The first is that the first medical device 10 acquires additional information of the plurality of target medical devices from a central station (central monitoring station) connected to the first medical device 10 through a local area network or a wide area network. The central station is used for monitoring one or more patients, and can acquire data acquired by the ultrasonic imaging equipment, the bedside monitor and the like in real time or non-real time for summarized display, so that the central station has additional information of each medical equipment of the medical equipment system. It is very convenient and quick for the first medical device 10 to obtain additional information from the central station.

The second is that the first medical device 10 receives broadcast information transmitted by the plurality of target medical devices through the local area network or the wide area network, and acquires additional information of the plurality of target medical devices according to the broadcast information. Wherein the broadcast information carries additional information of the plurality of target medical devices. I.e. the target medical device broadcasts its additional information in a local or wide area network, from which the first medical device 10 obtains the additional information of the plurality of target medical devices.

The third is that the first medical device 10 is directly connected to the plurality of target medical devices, thereby acquiring additional information thereof from the respective target medical devices.

In this embodiment, under the triggering of the display instruction, the first medical device 10 displays a selection control of the additional information on the main interface, so that the user clicks to select the additional information.

Step 2, the first medical device 10 receives a first selection instruction for selecting among the additional information of the plurality of target medical devices; in response to the first selection instruction, a second medical device is determined and a communication connection of the first medical device 10 with the second medical device 20 is established, wherein the second medical device 20 is at least one of the plurality of target medical devices. The communication connection between the first medical device 10 and the second medical device 20 may be a wired connection or a wireless connection, and the wireless connection may adopt a wifi, bluetooth, 4 g/5 g mobile network or other communication modes. The user selects one or more pieces of additional information among the displayed pieces of additional information of the target medical devices, the additional information identifying the medical device, the target medical device identified by the selected additional information being identified as the second medical device 20, the additional information identifying the patient, the one or more pieces of target medical devices of the patient identified by the selected additional information being identified as the second medical device 20, i.e., the second medical device 20 may be one or more (two or more). In this embodiment, the additional information of one target medical device is selected as an example, and as shown in fig. 3, the selected additional information is: room2ICU-E, i.e. the user selects the individual medical devices (possibly only one or possibly more) of the patient with patient bed number ICU-E in ward number 2, and the first medical device 10 establishes a communication connection with the medical device of the patient.

Step 3, the first medical device 10 displays the medical data type of the second medical device 20 on the display interface for the user to select. Specifically, the first medical device 10 displays a switch icon of the medical data type of the second medical device 20 on the display interface, the switch icon being a virtual switch. After the user operates the input device to trigger the switch icon, an opening trigger instruction for the switch icon is sent, and the first medical device 10 receives the opening trigger instruction for the switch icon; in response to the on trigger instruction, the medical data type of the second medical device is displayed on the display interface, as shown in fig. 4, and specifically, a list of medical data types of the second medical device 20 may be displayed for selection by the user. Several types of medical data, ECG (electrocardiography), respiratory Waveform (respiratory waveform), RM (respiratory mechanics), IBP (invasive blood pressure), NIBP (non-invasive blood pressure), spO2 (pulse oximetry) and Temp (body temperature), are shown in fig. 4 for user selection, each medical data type being turned on or off by a virtual switch b, only RM being turned off in fig. 4, i.e. the user has selected the other 6 medical data types. The medical data type of the second medical device 20 may include the type of physiological parameter data collected by the bedside monitor, the type of ventilation parameter data collected by the ventilator, the anesthesia machine, and the type of medical data collected by the infusion pump.

Of course, in some embodiments, the switch icon may be replaced by a physical key, or the physical key and switch icon are not required, and instead the medical data type of the second medical device 20 is displayed in a normalized manner.

Step 4, the first medical device 10 receives a second selection instruction for selecting among the medical data types of the second medical device 20; in response to the second selection instruction, determining a target medical data type of the second medical device 20 and acquiring target medical data of the second medical device 20, wherein the target medical data is medical data corresponding to the target medical data type. That is, which medical data type is selected by the user, the selected medical data type is the target medical data type, and the first medical device 10 acquires medical data corresponding to the target medical data type. For example, with the user selecting the ECG, respiratory Waveform, IBP, NIBP, spO2 and Temp of FIG. 4, the first medical device 10 acquires these types of medical data.

In some embodiments, the first medical device 10 may display the medical data type of the second medical device 20 on the display interface, and the virtual switch b of at least a part of the medical data types is turned on, in other words, the first medical device 10 provides a default medical data type, and the user considers that the medical data type may not be selected as needed, and the first medical device 10 uses the default medical data type as the target medical data type of the second medical device 20 if not selected. If the default is not met, the user may modify the default medical data type by turning on and off the corresponding virtual switch b to determine the target medical data type for the second medical device 20 based on the default medical data type and the second selection instruction. The default medical data type may be fixed or may be pre-associated with the examination site to which the ultrasound image belongs (e.g., heart, lung, blood vessel, diaphragm, etc.), and may vary from examination site to examination site.

Step 5, the first medical device 10 acquires medical data of the first medical device 10. The order of the steps in the above method is not limited, and may be before or after step 1, after step 2, after step 3, and the like, and may be before step 6.

Step 6, the first medical device 10 time-aligns the medical data of the first medical device 10 with the target medical data of the second medical device 20, and time-aligned displays the medical data of the first medical device 10 and the target medical data of the second medical device 20.

There are various ways to time align the data, and two ways are described below.

First, the first medical device 10 and the second medical device 20 communicate to obtain clock differences between them, and since the crystal oscillator of the first medical device 10 and the crystal oscillator of the second medical device 20 cannot be identical, clock differences between them, that is, clock differences between them, are generated due to the crystal oscillator. Further, the first medical device 10 adjusts the time of the target medical data of the second medical device 20 based on the clock of the first medical device 10, based on the clock difference, so that the medical data of the first medical device 10 and the target medical data of the second medical device 20 are time-aligned, that is, the medical data of both devices are time-synchronized. For example, the clock difference indicates that the clock of the second medical device 20 is 0.1 milliseconds faster, then the first medical device 10 may time align the medical data of the two devices by subtracting 0.1 milliseconds from the time of the target medical data.

Second, the first medical device 10 and the second medical device 20 communicate such that the second medical device 20 obtains a clock difference of both and adjusts the time of the target medical data of the second medical device 20 based on the clock of the first medical device 10 according to the clock difference, and transmits the time-adjusted target medical data of the second medical device to the first medical device 10, so that the medical data of the first medical device 10 and the target medical data of the second medical device 20 are time-aligned. For example, the first medical device 10 and the second medical device 20 communicate to obtain the clock difference between them, and the first medical device 10 transmits the clock difference to the second medical device 20. The second medical device 20 obtains the clock of the first medical device 10 according to the clock of the second medical device 20 and the received clock difference, and adjusts the time of the target medical data of the second medical device 20 based on the clock of the first medical device 10, such as stamping the target medical data with the time stamp of the clock of the first medical device 10, so that the target medical data is aligned with the medical data of the first medical device 10 in time, and then sends the target medical data to the first medical device 10. The target medical data received by the first medical device 10 is already synchronized in time with its own medical data.

After the two kinds of medical data are time-aligned, the first medical device 10 displays the medical data of the first medical device 10 and the target medical data of the second medical device 20 in time-aligned, that is, displays the medical data of itself and the target medical data in the same time coordinate system. Therefore, the user can see the medical data collected by at least two devices on the screen of one device, and each data is synchronous in time, so that the automatic integration and display of the medical data are realized, the degree of automation is high, and the medical staff can conveniently and rapidly master the comprehensive condition of the patient.

The scheme is particularly suitable for time alignment display of ultrasonic images and/or ultrasonic quantification indexes and physiological parameter data and/or ventilation parameter data. I.e. the first medical device may be an ultrasound imaging device and the second medical device may be a monitoring device (e.g. bedside monitor, central monitoring station, etc.), a ventilator, an anaesthetic machine or even an infusion pump, etc. The description will be given below taking an example in which the first medical device 10 includes an ultrasound imaging device, the medical data of the first medical device 10 includes an ultrasound image and/or an ultrasound quantification index, the second medical device 20 includes a monitoring device, and the target medical data of the second medical device 20 includes physiological parameter data and/or ventilation parameter data. Wherein the physiological parameter data may include at least one of an electrocardiographic waveform parameter, blood pressure, blood oxygen saturation, and impedance respiration. The ventilation parameter data may include at least one of airway pressure, airway flow, gas volume, tidal volume, and respiratory rate.

The medical data type of the second medical device 20 may include the type of physiological parameter data collected by the monitoring device, the type of ventilation parameter data collected by the ventilator, the anesthesia machine, the type of medical data collected by the infusion pump, etc.

In step 4, the first medical device 10 may specifically acquire the target medical data of the second medical device 20 in a variety of ways, which are illustrated below.

The second medical device 20 is at least one of a bedside monitor, a ventilator, an anesthesia machine, and an infusion pump for the patient, and the ultrasound imaging device may be directly connected to the at least one of the bedside monitor, the ventilator, the anesthesia machine, and the infusion pump to directly acquire the target medical data acquired by the medical devices.

Of course, the ultrasound imaging device may also be indirectly connected to at least one of the bedside monitor, the ventilator, the anesthesia machine, and the infusion pump through the central monitoring station, so as to acquire the target medical data acquired by these medical devices through the central monitoring station.

The other bedside monitors can be connected with the infusion pump, the breathing machine or the anesthesia machine, so that physiological parameter data acquired by the infusion pump, the breathing machine or the anesthesia machine are displayed on the bedside monitors, ventilation parameter data acquired by the infusion pump, the breathing machine or the anesthesia machine are also displayed, therefore, the ultrasonic imaging equipment can also acquire physiological parameter data acquired by the bedside monitors, ventilation parameter data acquired by the breathing machine or the anesthesia machine are also acquired by the bedside monitors, and medical data acquired by the infusion pump are acquired.

The specific manner in which the first medical device 10 acquires the target medical data of the second medical device 20 is related to the network topology relationship between the medical devices, and may be acquired through the network, which is not limited in detail.

In step 5, the ultrasound imaging device acquires medical data of the ultrasound imaging device, for example, based on a user operation of the ultrasound imaging device, the ultrasound imaging device scans a target tissue of a patient to obtain an ultrasound image, and the ultrasound image may be a two-dimensional image (B-mode), an M-mode image, a Color mode image, a PW mode image, a CW mode image, a TDI mode image, a three-dimensional image, or the like. The ultrasonic imaging device further displays an ultrasonic image on a display interface of a display of the ultrasonic imaging device, so that a user can further manually measure the ultrasonic image to obtain an ultrasonic quantification index, in this embodiment, taking the ultrasonic quantification index obtained by automatically measuring the ultrasonic image into consideration of the real-time performance of data display as an example for explanation, so that the medical data of the first medical device 10 and the target medical data of the second medical device 20 in step 6 can be displayed in time alignment in real time, and the user can conveniently grasp the condition of the patient in real time. Specifically, when the ultrasonic imaging device displays an ultrasonic image, a menu bar corresponding to the ultrasonic image is also displayed, and the menu bar comprises a plurality of measurement items for a user to select. The user selects a measurement item that is desired to be automatically measured, i.e., issues a measurement instruction for at least one measurement item of the plurality of measurement items. And the ultrasonic imaging equipment receives a measurement instruction of at least one measurement item in the plurality of measurement items, and responds to the measurement instruction, and ultrasonic quantification indexes corresponding to the ultrasonic images are obtained through measurement. In some embodiments, the ultrasonic image of each section may be associated with a measurement item to be automatically measured in advance, and after the ultrasonic imaging device maps (scans) the ultrasonic image to obtain the ultrasonic image, the ultrasonic image may be automatically measured according to the measurement item associated with the section of the ultrasonic image in advance, so as to obtain the corresponding ultrasonic quantization index.

The ultrasound image may be an ultrasound image of the heart, an ultrasound image of the lungs, an ultrasound image of the blood vessels or an ultrasound image of the diaphragm, among others. The ultrasound quantification index derived from the ultrasound image of the heart includes at least one of chamber volume, chamber wall thickness, myocardial velocity, blood flow velocity time integral, volume per beat, cardiac output, and myocardial strain. Ultrasound quantification indicators derived from ultrasound images of the lungs include the number of B lines and/or the percentage of B lines. Ultrasound quantification indicators derived from ultrasound images of blood vessels include vessel inner diameter and/or vessel strain. Ultrasound quantification indicators derived from ultrasound images of the diaphragm include diaphragm displacement and/or diaphragm thickness thickening rate.

Taking an ultrasound image as an example of the heart for illustration, there are various methods for automatically calculating the ultrasound quantification index of the heart, and several methods are described below.

One is an image segmentation method based on deep learning: a database of heart ultrasound images and labels of target areas (e.g., left chambers) is pre-constructed. Each heart ultrasonic image marks the boundary range of the region of interest (such as the left chamber), the deep learning image segmentation method can select network models such as FCN, unet, segNet, deepLab and Mask RCNN, and the models are trained by using a constructed ultrasonic image database (training set). After training is finished, an image to be segmented is input, an image with the same size as the input image is output through a network, and if the image contains a target area (such as a left room), a specific boundary range of the target area (such as the left room) is output, such as an area surrounded by dots in fig. 5. The ultrasound imaging apparatus may calculate the left chamber volume based on the left chamber boundary according to a formula for clinically calculating the chamber volume, such as Simpson's method (Simpson's method).

The other image segmentation method is based on other machine learning, for example, the ultrasonic imaging device pre-segments an ultrasonic image through image processing methods such as threshold segmentation, snake, level set, graphCut and the like, and a group of candidate target structure boundary ranges are obtained in the ultrasonic image; then, extracting features of the area surrounded by the boundary range of each candidate target structure, wherein the traditional features such as PCA, LDA, HOG, harr, LBP, SIFT and the like can be extracted, and the features can also be extracted by a neural network; and then matching the extracted features with features extracted from the marked boundary ranges in the database, classifying by using a linear classifier, an SVM, a random forest or a neural network and other discriminators, and determining whether the current candidate boundary range contains a target area (such as a left room). The left chamber volume can be calculated according to the left chamber boundary according to a formula for clinically calculating the chamber volume, such as Simpson method.

The method for automatically calculating the cardiac ultrasound quantitative index can also be used for carrying out image processing methods such as threshold segmentation, morphological transformation, boundary extraction and the like based on the frequency spectrum images of PW and CW modes to obtain a blood flow velocity value. And further obtaining blood flow velocity time integral, each stroke volume, heart displacement and the like according to the blood flow velocity value.

In step 6, the medical data of the first medical device and the target medical data of the second medical device are displayed in time alignment, which may be that the ultrasound imaging device displays the ultrasound image, the curve of the ultrasound quantification index, and the curve of the physiological parameter data and/or the curve of the ventilation parameter data in time alignment according to the same time coordinate system. The time-aligned display of the medical data of the first medical device and the target medical data of the second medical device may be real-time-aligned display, or may be time-aligned display of data (such as historical medical data) of a certain time period. The display interface of the ultrasound imaging device may or may not display this time coordinate system, for example, a timeline. The curves of the ultrasonic quantification index and the curves of the physiological parameter data and/or the curves of the ventilation parameter data can share a time axis, for example, as shown in fig. 6-8, the curves are distributed sequentially from top to bottom, so that the abscissa (time) of each curve is the same, and a user can focus on the ordinate of each curve, thereby well mastering the comprehensive condition of the patient. This timeline may or may not be displayed (e.g., hidden) on the display interface.

As shown in fig. 6, the ultrasound imaging device display interface displays an ultrasound B image of the heart, a chamber volume curve c, a blood pressure waveform d, and an ECG waveform e. The display interface of fig. 7 shows an ultrasound B image, an M image, a chamber volume curve c and an ECG waveform e of the heart.

For another example, when displaying the blood vessel ultrasound image, the inside diameter of the blood vessel and the like are also displayed simultaneously.

The medical data of the first medical device and the target medical data of the second medical device at the same moment have a certain correlation, and can be used for judging the time alignment accuracy of the first medical device and the target medical data of the second medical device. Specifically, the first medical device obtains the accuracy of time alignment according to the ultrasound image and/or the ultrasound quantification index, and the physiological parameter data and/or the ventilation parameter data. For example, for an ultrasound image of the heart, the ultrasound image, the ultrasound quantization index, and part of physiological parameter data (such as ECG waveform) will change along with the change of the cardiac cycle, and the peaks and troughs thereof have a certain correspondence, so that the degree of synchronization of each data can be determined according to the correspondence, thereby obtaining the accuracy of time alignment.

That is, the user drags to which progress, and the display interface displays the ultrasound image, the curve of the ultrasound quantification index, and the curve of the physiological parameter data and/or the curve of the ventilation parameter data at the time corresponding to which progress; therefore, the user can not only see various data in real time, but also operate the man-machine interaction device to drag the playing progress bar h back, so that the previous ultrasonic image, the curve of the ultrasonic quantization index, the curve of the physiological parameter data and/or the curve of the ventilation parameter data and the like are seen.

Of course, the historical medical data may also be viewed in other manners, in an embodiment, the first medical device receives a review instruction for reviewing the historical data, and in response to the review instruction, obtains the historical medical data of the first medical device and the historical target medical data of the second medical device, for example, the display interface has a review virtual button, and the user triggers the review virtual button to send the review instruction for reviewing the historical data, so that the first medical device obtains the historical medical data of the first medical device and the historical target medical data of the second medical device from the memory. The specific process of performing time alignment and time alignment display on the two medical data is the same as the above embodiment, that is, the medical data of the first medical device in the above embodiment is changed to the historical medical data of the first medical device, and the target medical data is changed to the historical target medical data, and other processes are the same and are not described herein.

The user may also temporarily modify the medical data type of the second medical device displayed by the display interface. For example, the medical data type of the second medical device 20 is fixedly displayed on the display interface, and the user can perform reselection at any time through the human-computer interaction device. The first medical device receiving a third selection instruction to reselect among the medical data types of the second medical device; responsive to the third selection instruction, re-determining target medical data of the second medical device; the specific process of time-aligning the medical data of the first medical device with the target medical data of the second medical device, and time-aligning the medical data of the first medical device with the target medical data of the second medical device, where the specific process of time-aligning the two medical data and time-aligning the medical data is the same as that of the above embodiment, that is, the target medical data of the second medical device in the above embodiment is changed to the target medical data of the second medical device, and the other processes are the same and are not repeated herein.

In the embodiment shown in fig. 1, part of the steps may be omitted, and this will be described below by way of a second embodiment. In the second embodiment, a data display method of a medical device system is shown in fig. 10, and includes the following steps:

Step 1', the first medical device 10 displays additional information for a plurality of target medical devices. Specifically, the first medical device 10 receives a display instruction of additional information of a plurality of target medical devices; in response to the display instruction, additional information of the plurality of target medical devices is displayed on a display interface of the first medical device. The specific process is the same as step 1 of the first embodiment, and will not be described here.

Step 2', the first medical device 10 receives a first selection instruction for selecting among the additional information of the plurality of target medical devices; in response to the first selection instruction, the second medical device is determined and a communication connection of the first medical device 10 with the second medical device 20 is established. The specific process is the same as step 2 of the first embodiment, and will not be described here.

Step 3', time alignment based on the reference clock. A reference clock may be determined, wherein the reference clock is a clock of the first medical device or the second medical device or the other medical device; and then time aligned based on the reference clock. The specific modes can be varied, and two modes are exemplified below.

One is to align the times (e.g., clocks) of the first medical device and the second medical device. Specifically, the first medical device determines a reference clock, and the first medical device aligns the times of the first medical device and the second medical device according to the reference clock. For example, the first medical device 10 and the second medical device 20 communicate to obtain a clock difference between them, and the clock difference may specifically be a clock difference between two medical device crystal oscillators. If the reference clock is the clock of the first medical device, the second medical device 20 adjusts its own clock with the clock of the first medical device 10 as a reference, so that the time of the first medical device and the time of the second medical device are synchronized. If the reference clock is the clock of the second medical device, the first medical device adjusts the clock of the first medical device based on the clock of the second medical device, so that the time of the first medical device and the time of the second medical device are synchronized. If the reference clock is the clock of the other medical devices, the first medical device 10 and the second medical device 20 respectively communicate with the medical device where the reference clock is located, so as to obtain a corresponding clock difference, the first medical device adjusts the own clock based on the reference clock to synchronize the time of the first medical device and the reference clock, and the second medical device adjusts the own clock based on the reference clock to synchronize the time of the second medical device and the reference clock.

After the first medical device and the second medical device are time aligned based on the reference clock, medical data of the first medical device and medical data of the second medical device may be acquired. The medical data of the second medical device may be medical data associated with the medical data of the first medical device, for example, the medical data of the first medical device includes an ultrasound image, and the medical data of the second medical device may be different from one examination site to another in advance associated with an examination site (e.g., heart, lung, blood vessel, diaphragm, etc.) to which the ultrasound image belongs. Of course, the medical data of the second medical device may also be fixed. The specific process of acquiring the medical data of the first medical device and the medical data of the second medical device may be the same as step 5 and step 4, which are not described herein.

Another is to time align the medical data of the first medical device and the second medical device. Specifically, the first medical device acquires medical data of the first medical device and medical data of the second medical device, and time-aligns the medical data of the first medical device and the medical data of the second medical device according to the reference clock. For example, the first medical device adjusts the time of the medical data of the first medical device according to the clock difference between itself and the reference clock, and the second medical device adjusts the time of the medical data of the second medical device according to the clock difference between itself and the reference clock.

The time alignment based on the reference clock is substantially the same as that in the first embodiment, and will not be described here.

And 4', the first medical device displays the medical data of the first medical device and the medical data of the second medical device on a display interface of the first medical device in a time alignment mode. The specific process is the same as step 6 of the first embodiment, and will not be described herein.

In this embodiment, the first medical device is an ultrasound imaging device, and correspondingly, medical data of the first medical device is an ultrasound image and/or an ultrasound quantization index, and the ultrasound quantization index is an ultrasound quantization index corresponding to the ultrasound image; the second medical device is a central station or a monitor, and medical data of the second medical device is physiological parameter data and/or ventilation parameter data; this is the same as embodiment one, so that the ultrasound image and/or ultrasound quantization index, physiological parameter data and/or ventilation parameter data specifically include which, how to perform time alignment display, etc., and are the same as embodiment one, and will not be described here again.

The method comprises the steps that when the first medical device performs time alignment display on medical data of the first medical device and medical data of the second medical device on a display interface, acquisition time of the medical data of the second medical device is also acquired; and displaying a second medical event identifier at a designated position corresponding to the acquisition time according to the same time coordinate system of various medical data displayed on the display interface. Specifically, when the second medical device sends the medical data of the second medical device to the first medical device, the second medical event identifier is displayed at the designated position corresponding to the acquisition time according to the same time coordinate system, so that the user can be reminded conveniently.

in this embodiment, the medical device system includes a plurality of medical devices, wherein the plurality of medical devices includes an ultrasound imaging device and a third medical device. The display method of the medical device system is applied to a third medical device among the plurality of medical devices of the medical device system. As shown in fig. 11, the method includes the steps of:

step 1', the third medical device establishes a communication connection with the ultrasound imaging device. For example, the third medical device has a network setting interface, the user calls out the network setting interface through a preset key, and the network setting interface displays a connection mode of a local area network or a wide area network for the user to select, and the connection mode is wired, wireless or the like, so that communication connection with the ultrasonic imaging device is established.

Step 2", the third medical device obtains the physiological parameter data and/or the ventilation parameter data of the target object, and displays the curve of the physiological parameter data and/or the curve of the ventilation parameter data on the display interface of the third medical device according to the same time coordinate system. The third medical device may be various types of medical devices such as a central monitoring station, a monitor, a ventilator, an anesthesia machine, an infusion pump, as well as various types of computers, mobile terminals, etc. The present embodiment is described by taking a central monitoring station as an example. Specifically, the third medical device acquires physiological parameter data and/or ventilation parameter data of a plurality of detection objects (such as a plurality of patients), for example, may acquire physiological parameter data of the plurality of patients from respective bedside monitors, and acquire ventilation parameter data of the plurality of patients from respective ventilators or anesthesia machines, and further display physiological parameter data overviews and/or ventilation parameter data overviews of the plurality of detection objects on a display interface of the third medical device. As shown in fig. 12, the physiological parameter data overview j includes brief information of physiological parameter data, and similarly, the ventilation parameter data overview includes brief information of ventilation parameter data. The third medical device receives a selection instruction for the target object, and in response to the selection instruction, displays a curve of physiological parameter data and/or a curve of ventilation parameter data of the target object according to the same time coordinate system on the display interface, which corresponds to displaying a detail view k of the target object in response to the selection instruction on the display interface, wherein the detail view k displays the curve of physiological parameter data and/or the curve of ventilation parameter data of the target object in the same time coordinate system. That is, after the user sees the data overview of the plurality of patients, and selects one patient, if the patient of 02 bed is selected, the display interface of the third medical device displays detailed data of the selected patient: the curves of the physiological parameter data and the ventilation parameter data are shown in a plurality of curves on the right side of fig. 12, so that a user can know the condition of a patient in detail, and the patient can be monitored better.

In this embodiment, as shown in fig. 12, the curves of the physiological parameter data and/or the curves of the ventilation parameter data are displayed according to the same time coordinate system, specifically, each curve shares a time axis, that is, the abscissa (time coordinate) of each curve is the same, and each curve is arranged from top to bottom, so that the comparison is convenient for the user.

Step 3", the third medical equipment acquires an ultrasonic image and/or an ultrasonic quantization index of the target object from the ultrasonic imaging equipment, wherein the ultrasonic quantization index is an ultrasonic quantization index corresponding to the ultrasonic image. The specific process of the ultrasonic imaging device scanning the target object to obtain an ultrasonic image and further measuring the ultrasonic image to obtain an ultrasonic quantization index is shown in the embodiment shown in fig. 1, and is not described herein. After the ultrasonic imaging device obtains the ultrasonic image and/or the ultrasonic quantization index, the ultrasonic image and/or the ultrasonic quantization index is sent to the third medical device.

And 4', acquiring the ultrasonic image of the target object and/or the acquisition time of the ultrasonic quantification index by the third medical equipment. The ultrasonic imaging device records the acquisition time when obtaining the ultrasonic image and/or the ultrasonic quantification index, so that the acquisition time is sent to the third medical device when sending the ultrasonic image and/or the ultrasonic quantification index to the third medical device. Of course, the third medical device may also take the time when the ultrasound image and/or the ultrasound quantification index is received as the acquisition time.

And 5', the third medical equipment displays the ultrasonic event identifier L at the designated position corresponding to the acquisition time according to the same time coordinate system, namely, displays the ultrasonic event identifier L on the detail view k. For example, when the third medical device detects that the ultrasonic imaging device sends the ultrasonic image and/or the ultrasonic quantification index of the target object under the acquisition time to the third medical device, the ultrasonic event identifier is displayed at the designated position corresponding to the acquisition time according to the same time coordinate system. In this embodiment, specifically, the third medical device displays the ultrasound event identifier L near the acquisition time according to the same time coordinate system. Thus, not only is an indication of the occurrence of an ultrasonic event, but also the approximate time it occurred.

The acquisition time may be a time or a time period, and if the time period is adopted, the designated position corresponding to the acquisition time may be a position corresponding to a start time, an intermediate time, an end time, and the like of the acquisition time. If the acquisition time adopts a time period, after the ultrasonic image and/or the ultrasonic quantization index are received and then the ultrasonic event identifier L is displayed, a new ultrasonic image and/or the ultrasonic quantization index may be received in the time period, and then the update identifier may be displayed so as to prompt the user that the ultrasonic image and/or the ultrasonic quantization index is updated. Specifically, when the third medical device detects that the ultrasonic imaging device sends the ultrasonic image and/or the ultrasonic quantization index of the target object updated at the acquisition time to the third medical device, the update identifier is displayed on the display interface.

The third medical device may also display physiological parameter data and/or ventilation parameter data corresponding to the acquisition time in the vicinity of the ultrasound event identification L, as shown by display box m in fig. 12. The method is convenient for a user to analyze various medical data of the acquisition time.

Step 6', the third medical device receives the operation instruction for the ultrasonic event identification, and the ultrasonic image and/or the ultrasonic quantification index of the target object are displayed on the display interface in response to the operation instruction for the ultrasonic event identification. For example, a window (shown as a U-View window in FIG. 12) may be displayed on the display interface, within which an ultrasound image and/or ultrasound quantification index of the target object is displayed. Therefore, the user can view the ultrasonic image and/or ultrasonic quantification index on the left side and view the physiological parameter data and/or ventilation parameter data on the right side, and the information comprehensive degree is high and is very convenient.

The ultrasound image of the target object may comprise a plurality of frames of ultrasound image frames, such as consecutive frames of ultrasound image frames. The third medical device can specifically control and play the multi-frame ultrasonic image frame in the window through the play key n, and display an ultrasonic quantization index corresponding to the multi-frame ultrasonic image frame. The ultrasonic quantization index corresponding to the multi-frame ultrasonic image frame may be an average value of ultrasonic quantization indexes of the multi-frame ultrasonic image frame, as shown in a U-View window of fig. 12, an ultrasonic B image and an ultrasonic M image are displayed, and a numerical value of the ultrasonic quantization index corresponding to the multi-frame ultrasonic image frame is displayed on the left side. Thus, the user can view and operate the dynamic ultrasonic image and the ultrasonic quantification index corresponding to the dynamic ultrasonic image.

The third medical device may further receive a freeze instruction for one of the plurality of ultrasonic image frames, for example, the user clicks the play key n to pause play, and in response to the freeze instruction, display physiological parameter data and/or ventilation parameter data corresponding to the one ultrasonic image frame in time alignment within a window, and specifically, may display a curve of physiological parameter data and/or a curve of ventilation parameter data corresponding to the one ultrasonic image frame in time alignment within the window, as shown by waveforms on M images in the window of fig. 12. The ultrasound quantization index corresponding to the one frame of ultrasound image frame may also be displayed in a window, as shown in the upper right corner of the window of fig. 12. Therefore, the user can see not only the ultrasonic image and ultrasonic quantification index of the patient but also the physiological parameter data and ventilation parameter data which are synchronous in time in the window, and the medical data collected by different equipment are high in integration degree and convenient to view. The time alignment display, that is, the time synchronization display, is the same as the first embodiment, and a detailed description thereof will be omitted.

The playing progress bar q can be displayed near the playing key n, the third medical device receives a dragging instruction for the playing progress bar q, and the ultrasonic image, the ultrasonic quantization index and the curve of the physiological parameter data and/or the curve of the ventilation parameter data are dynamically displayed in a linkage mode in response to the dragging instruction.

The third medical device may also display a thumbnail of the multi-frame ultrasound image frame within a window, as shown under play key n in fig. 12. The thumbnails of the multiple frames of ultrasonic image frames can be displayed in a sliding/dragging mode, namely, a user can slide/drag the thumbnails so that the ultrasonic image to which the wanted thumbnail belongs can be displayed, and the operation is very convenient.

The update identifier may also be displayed in a window, and when the third medical device receives an instruction for selecting the update identifier, that is, when the user selects (e.g. clicks on) the update identifier, the ultrasound image and/or the ultrasound quantization index of the target object are updated in the window, that is, a new ultrasound image and/or the ultrasound quantization index of the target object is displayed in the window, and the specific display manner and the specific content displayed are the same as the operation instruction for responding to the ultrasound event identifier, which will not be described herein.

If an operation instruction for identifying the ultrasonic event is received, the third medical device can also display an identification p of the acquisition time on the display interface, wherein the identification p of the acquisition time is represented according to at least one mode of characters, colors, lines and shapes. The mark p of the acquisition time may be displayed on any curve in the detail view k, may be displayed on a time coordinate axis of the time coordinate system, and may be displayed at any position of a straight line perpendicular to the time coordinate axis of the time coordinate system. In this embodiment, a line perpendicular to the time axis of the time coordinate system is used as the mark p of the acquisition time, as shown by the white line p in fig. 12, so that the point where the white line intersects the physiological parameter curve and the ventilation parameter curve is the acquisition time, and the user knows the physiological parameter value and the ventilation parameter value corresponding to the acquisition time by seeing the values corresponding to the intersection points, which is very convenient.

In summary, the technical scheme provided by the invention not only can integrate the medical data with clinical relevance among a plurality of medical devices, but also can time align and synchronously display each medical data, and the medical data is intensively displayed on a display interface in the same time coordinate system, thereby providing convenience for a clinician from the dimensions of data integration, display and the like, facilitating the clinician to evaluate the condition of the patient from more dimensions (ultrasound, physiological parameters, respiratory parameters and the like), and improving the working efficiency of the doctor.
