Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The existing medical monitoring equipment with the waveform diagram and the parameter diagram has a single display mode, and cannot switch or highlight one diagram, so that the reading of the parameters or the waveforms is greatly limited.

In one embodiment, as shown in fig. 1 and 5, an interface interaction method is applied to a specific medical monitoring, monitoring and detecting device, such as a ventilator, an anesthesia machine, etc., which can reflect the physiological status of a patient in real time, and such a device should be provided with an interactive screen capable of being controlled by touch, and can collect corresponding instructions generated by a user by touching a specific area. The method comprises the following steps:

s110, an initial trigger area is defined on the interactive screen, and whether a preset object touches the interactive screen of the medical monitoring device is monitored.

In a specific application scenario, as shown in fig. 5, the start trigger area is a virtual key of the value at the top of the screen.

The preset object can be set as a finger or other object with biological activity, so that the interaction screen can be changed according to the identification action only when the medical staff performs the action, and the occurrence of mistaken touch conditions (such as possible limb touch in the process of rescuing patients) is prevented. The touch pen can be set as an object with special electrical performance, such as a specific touch pen (capacitance pen) and the like, so that the false touch can be reduced, and the propagation of bacteria and viruses caused by touch can also be reduced.

And S120, if the occurrence of touch is monitored, displaying an interactive selection interface corresponding to the initial trigger area, wherein the interactive selection interface is provided with a plurality of independently partitioned content pages and a switching identification area capable of switching among the plurality of content pages.

In a specific application scenario, as shown in fig. 5, 2 main regions are set in the switching identification region, that is, a strip-shaped waveform diagram region mainly displaying a waveform diagram and a numerical value diagram region located below the strip-shaped display region and having multiple sets of real-time data. A defined switching identification area is arranged between the oscillogram area and the numerical graph area.

S130, monitoring whether the switching identification area is touched by a preset object or not, and if the switching identification area is touched, highlighting a target content page in a plurality of pages.

In a specific application scenario, the manner of highlighting may be a manner of increasing the display area of the extended target content page. Such as making the display area of the target content page significantly expanded compared to before selection; meanwhile, in a plurality of content pages arranged in an equal volume mode, the non-target content pages are reduced to form of thumbnail icons and the like, and the area of the initial state in the interactive selection interface is made.

While the display area is increased, it is preferable to expand the number of element contents in the displayed target content page by retrieving system/external data without enlarging the size of the elements in the target content page (e.g., increasing the font size of the data, etc.). For example, on a general-size display device of a current medical monitoring device, the total number of multiple displayed monitoring values generally does not exceed 45, and generally relates to a plurality of group data, so that the number of each displayed group data value is more limited, and especially for a scene in which a change trend of data before and after needs to be mastered, the number of the monitoring values is too small, which is not beneficial for medical staff to directly master the change trend of physiological parameters of a patient. After the display area of the content page is expanded, the increased area is used for displaying more data, so that medical staff can visually know the data change trend and further master the change trend of the physiological parameters of the patient.

By adopting the embodiment, medical staff can highlight the oscillogram or the parameter graph in the medical monitoring equipment through simple operation to obtain more comprehensive and more parameter quantity, so that the medical staff can directly and quickly master the current state and the change trend of the physiological and pathological parameters of the patient.

As shown in fig. 2, this embodiment includes the following steps as a preferred implementation:

step S210, monitoring whether a preset object touches an initial trigger area on an interactive screen;

step S220, if touch is monitored, displaying an interaction selection interface corresponding to the initial trigger area, wherein the interface is preset with a plurality of content pages and a switching identification area for switching the content pages;

and step S230, expanding the area of the target content page to cover other content pages.

In practical application scenarios, a display screen of a general clinical care monitoring device such as a monitor and a ventilator is limited by a use scenario, and needs to be limited to the periphery of a patient bed, and the size of the display screen is not too large, and meanwhile, in order for a medical care worker to be able to quickly view data of a display at a proper distance, the data that the medical care worker wants to see currently needs to be displayed as much as possible in a limited display area, so that the area of a target content page is enlarged as much as possible to display more related content.

The same as the application scenario of the previous embodiment, the interactive selection interface initially displayed in this embodiment includes two main content pages arranged up and down, which are respectively a oscillogram region and a parameter map region, and in a general scenario, the oscillogram mainly reflects periodic physiological parameters of a patient, such as respiration, heart rate, pulse, and the like; the parameter map displays real-time parameters such as blood oxygen and blood pressure, which have large variation amplitude with time. Therefore, in the embodiment of the invention, the parameter map is selected to be highlighted, the waveform map is hidden, and the parameter map area is highlighted, even if the parameter map area occupies the whole interactive selection page. In combination with the complete display area of one display screen in the foregoing embodiments, the display screen includes a plurality of interactive selection interfaces arranged in the form of bookmarks (or described as similar to arrangement of medical records), each interactive selection interface may include a plurality of content pages, a horizontally arranged tag mode may be selected at the top and/or bottom of the interface in the arrangement mode, and a vertically arranged tag mode may also be displayed on the left and/or right side of the interface, respectively, as required.

After the target content page is highlighted, the area of the whole interactive selection interface is completely occupied by the parameter map area except the switching identification area (at this time, the switching identification area is located at the edge of the target content page behind the expanded area). As shown in fig. 6, the number of parameters is significantly increased compared to before the handover.

As a preferred embodiment, the switching identification area 130 has an initial direction indicator (pointing to the upper side of the screen in fig. 8), as shown in fig. 5 and 6 and fig. 8. In practical use scenarios, the operational requirements for medical devices are as direct and intuitive as possible in order to meet emergency scenarios while reducing unnecessary contact. For example, a common household tablet personal computer has a complex multi-finger and multi-gesture operation mode, can realize various operations such as screen capture, switching, amplification and reduction, and the like, and although the achievable functions are more comprehensive, the operation is too complex, the multiple fingers are required to act simultaneously, the operation is time-consuming, the recognition success rate is limited, and sudden scenes such as rescue and the like which need to be directly fed back by one operation cannot be dealt with; in the case of dealing with infectious disease patients, it is also required to reduce the chance of people contacting medical instruments and equipment as much as possible, and to simplify the operation mode as much as possible. After the touch, the target content page 120 starts to move along the direction identified by the initial direction until the other content pages 110 in the interactive selection interface are covered. The switching identification area moves along with the edge of the target content page in the moving process, and the edge of the target content page is guaranteed to be always fixed before and after the target content page covers other content pages (the edge is an intersection line of the target content page and other content pages in the interactive selection interface).

By setting the icon of the initial direction identifier, the user can realize the function of highlighting (maximizing the target content page area) by directly touching at one time.

As shown in fig. 5 and 6 and fig. 8 and 9, consistent with the application scenario of the previous embodiment, the embodiment mainly includes the following steps:

s310, monitoring whether a preset object touches an initial trigger area on the interactive screen; s320, if touch is monitored, displaying an interaction selection interface corresponding to the initial trigger area, wherein the interface is preset with a plurality of content pages and a switching identification area for switching the content pages; s330, monitoring whether the preset object touches the switching identification area; the selected content page area is expanded to occupy all of the interactive selection interface.

Specifically, in step S340, after the target content page 120 starts to occupy the interactive selection interface, the initial direction identifier of the switching identification area 130 is changed to a direction opposite to the initial direction identifier; during the expansion of the target content page 120 and after the expansion is finished and other content pages 110 are covered, if the switching identification area 130 with the opposite direction identifier is touched, the target content page is returned to the initial position of the interactive selection interface.

In an application scene, after the switching identification area 130 is touched, the target content page 120 starts to move in the direction indicated by the initial direction identifier, and in the moving process, preferably, a certain delayed animation effect can be set; meanwhile, in the process from the beginning of the movement to the end of the movement (the target content page occupies all the interactive selection pages, or is limited to be described as that one edge of the selected content page moves to coincide with the edge of the interactive selection pages), and after the movement is finished (occupies the whole area), the direction of the initial direction mark in the switching identification area starts to display the opposite direction, as shown in the figure, an upward movement icon is displayed when the movement is started, and a downward icon is displayed during and after the movement is finished.

No matter at any stage after the movement starts, the icon with the mark in the opposite direction is touched, and the selected content page in the movement starts to move from the current position to the initial position until the selected content page returns to the initial position.

In an additional implementation scenario, after the initial position is restored, the direction indicator of the icon remains unchanged (still opposite to the initial direction indicator), and after the icon area is touched again, the selected waveform diagram area begins to occupy the interactive selection interface.

In an additional implementation scenario, in order to directly highlight the oscillogram region 110, the icon of the identification region may be switched to directly display the opposite sign direction at a regular touch (e.g. continuously touching 2 within a certain time period), and start to move along the sign direction until the area of the interactive selection interface is occupied. In the process of movement, the direction mark displays the opposite direction, and the direction mark can be folded back to the initial position at any time.

By the technical scheme of the embodiment, the initial state of the initial interactive selection interface can be returned at any time in the process of switching the content page, the medical staff can be ensured to operate at any time in the using process, and the initial interface with the most information can be quickly returned after the information to be acquired is returned, so that other current physiological parameters of the patient can be further comprehensively known.

In one embodiment, considering that the hardware of the display screen of such a medical device generally has only a single display function, before and after touching the switching recognition area, an identifier capable of identifying whether the touch is successful needs to be given. Preferably, the marking is performed by a change in transparency. Before touching, the translucent state may be preferred, and at the time of touching, the transparency is 100%, and after touching, the translucent state is restored.

Through the embodiment, the identification of successful touch is carried out by adopting the transparency, the existing display equipment can be directly utilized to the maximum extent, and only the software part needs to be modified. (vibration, sound, etc., the existing display device does not support, need to be modified hardware level)

In a daily use scene, if the false touch occurs, the user is required to perform the return operation after the false touch result occurs, that is, after the displayed content is completely switched, and the waiting time is long. In the present embodiment, an operation suspension confirmation process is given.

In this embodiment, after the touch is detected (the preset object touch in any of the foregoing scenes, such as the touch start triggering area and the switching identification area), it is monitored whether the predetermined object that has touched generates the sliding displacement beyond the preset range. Preferably, the preset range of the sliding displacement is a circle with a radius of 1cm, and after the touch occurs, if the touch is a false touch or a user repels to maintain the current page, the false touch can be determined by moving a finger or a capacitance pen which is already in a touch state to exceed 1cm, and the preset operation is cancelled.

In an actual application scenario, a corresponding page action may set a corresponding gradual animation, which is matched with the slide cancel operation described in this embodiment. When the initial trigger area and the switching identification area are touched, the label page (or the medical record card and other forms) corresponding to the initial trigger area starts to be displayed in a transparency mode. Similarly, when the switching identification area is touched, in addition to the reminding in the mode that the transparency is changed, the moving direction and/or moving trend animation of the target content page can be set to remind medical personnel that the switching identification area is touched at the moment, and the return to the initial state can be cancelled by sliding a finger or a capacitance pen and the like.

An embodiment, as shown in fig. 4, an interface interaction unit for controlling a display screen with an interaction function to interact and display, includes:

a first touch monitoring module 150 for monitoring whether the initial trigger area of the interactive screen is touched by the selected object; the module simultaneously monitors whether a switching identification area in an interactive selection interface corresponding to the initial trigger area is touched by a target object.

The control module 110, which is the touch monitoring module for communication, performs corresponding processing according to the monitoring result of the first touch monitoring module 150:

when the first touch monitoring module 150 monitors that the initial trigger area of the interactive screen is touched, the control unit displays a corresponding interactive selection interface in a specific form (the form of the label page or the medical record card) according to preset display content.

In the figure, in the interactive selection interface under the value, the default initial state is mainly divided into 4 areas, namely, an airway pressure Paw oscillogram area located above, three areas, namely, a positive end-expiratory pressure Peep, a mitral valve movement distance Mve and a lung compliance Cdyn, which are located below the oscillogram area in parallel, wherein in the three areas, in the initial state (shown together with the oscillogram area), the number of the positive end-expiratory pressures Peep is 15, the number of the mitral valve movement distances Mve is 20, and the number of the lung compliance Cdyn is 15.

After the interactive interface is displayed, the second touch monitoring module 160 works to monitor whether the switching identification area in the current interactive selection interface is touched for the second time, and after the touch, the three areas in the interface move upwards integrally to cover the oscillogram area. At this time, the number of the numerical end-of-breath positive pressures Peep displayed in the three regions was 21, the number of the mitral valve movement distance Mve was 28, the number of the lung compliance Cdyn was 21, and the observable number was 70. Through the scheme of this embodiment, can increase the numerical value display quantity in same screen by a wide margin, make things convenient for medical personnel to know the state of current disease fast directly perceived.

In an embodiment, the scenario of the embodiment is the same as that of the previous embodiment, and the communication module 120 and the storage module 130 are added on the basis of the original architecture.

The communication module 120 acquires data transmitted by external monitoring equipment, sensors, networks and other equipment in real time, transmits the data to the control module 110, is processed and arranged into a general data form/format in the unit by the control module 110, and transmits the processed and arranged data to the storage module 130 for storage, wherein the data includes positive end respiratory pressure Peep, mitral valve movement distance Mve, lung compliance Cdyn and airway pressure Paw waveform data applied in the embodiment.

In a real-time scenario, when the three areas of positive end-expiratory pressure Peep, mitral valve movement distance Mve and lung compliance Cdyn expand the display area (highlight) to the top of the screen in the interactive selection interface, the displayed data is retrieved from the storage module 130 by the control module 110.

As a preferred embodiment, when the control module 110 controls the interactive selection interface to switch the display data content, the airway pressure Paw waveform data, the positive end-expiratory pressure Peep, the mitral valve movement distance Mve and the lung compliance Cdyn are still collected, generated and stored by the control module 110, the communication module 120 and the storage module 130, and only the control module 110 adjusts the number and types of output display data according to the size of the screen and the display area. Through the technical scheme of this embodiment, can guarantee when switching the display content, still handle relevant data in real time, when needing to observe corresponding data again, direct output display can, save interrupt data display, restart the time of handling, guaranteed the continuity and the real-time nature of data display in medical care's process.
